Description

A sealed installation structure for smart street lamp poles for the Internet of Things

Technical Field

The present invention relates to the field of smart street lamps, and in particular to a sealed installation structure of a smart street lamp pole for the Internet of Things.

Background technique

In the field of smart street lights, it is well known that different types of mounting structures are used to achieve the installation and fixation of smart street light poles. In the process of studying and implementing the installation and fixation of smart street light poles, researchers found that the mounting structures in the prior art have at least the following problems:

There are many parts involved, which makes disassembly and assembly complicated and cannot meet the needs of quick disassembly and assembly; the waterproof sealing performance is poor, and it cannot prevent liquid from penetrating into the interior of the installation structure along the lamp pole, and thus cannot meet the long-term waterproof sealing requirements of outdoor installation.

In view of this, it is necessary to develop a sealed installation structure for a smart street lamp pole for the Internet of Things to solve the above problems.

Summary of the invention

In order to overcome the problems existing in the above-mentioned installation structure, the technical problem to be solved by the present invention is to provide a sealed installation structure for a smart street lamp pole for the Internet of Things, which not only involves fewer parts and is easy to disassemble and assemble, but also has good waterproof performance and can meet the waterproof sealing requirements of long-term outdoor installation.

As for the installation structure, the sealing installation structure of the smart street lamp pole for the Internet of Things to solve the above technical problems of the present invention includes:

A mounting base is defined to form a mounting cavity, wherein the top of the mounting base is open to form a mounting opening communicating with the mounting cavity;

A holding member defining a holding cavity, the holding member comprising a docking section at least partially connected to the mounting cavity through the mounting opening and a holding section exposed from the mounting opening; and

A mating member surrounding at least a portion of the fastening member and the mounting base and defining a mating cavity, comprising an extrusion portion surrounding at least a portion of the holding section and a mating portion detachably surrounding at least a portion of the mounting base;

The outer diameter of the clamping section is in the shape of a truncated cone which gradually increases from top to bottom, and an extrusion surface which matches the outer periphery of the clamping section is formed on the inner periphery of the extrusion portion; at least two upper give-way grooves and at least two lower give-way grooves are radially arranged in the circumferential direction of the clamping member; the upper give-way grooves extend downward from the upper opening of the clamping member and penetrate the inner and outer side walls of the clamping member, and the lower give-way grooves extend upward from the lower opening of the clamping member and penetrate the inner and outer side walls of the clamping member, so that when the outer periphery of the clamping member is subjected to radial compressive force, elastic deformation can occur, so that the clamping member contracts radially to switch from a loose state to a clamping state; the mating member can slide up and down relative to the mounting base to switch between a locked state and an unlocked state, and when the mating member slides downward relative to the mounting base, the extrusion surface continuously applies the radial compressive force to the outer periphery of the clamping member.

Optionally, the upper give-way grooves are configured to be composed of at least one give-way subset, each give-way subset includes a pair of upper give-way grooves arranged adjacent to each other, the corresponding pair of upper give-way grooves in each give-way subset are spaced apart from each other to form a spacing space therebetween, and the corresponding spacing space in each give-way subset is aligned with a corresponding one of the lower give-way grooves.

In practice, it is found that the mating parts are prone to loosening during the long-term cooperation with the mounting base and the clamping parts, which leads to unstable installation of the lamp pole and broken sealing. In order to solve this problem, the sealing installation structure of the smart street lamp pole for the Internet of Things is further improved: a locking ring is formed on the outer periphery of the clamping part and located between the docking section and the clamping section, and the locking ring protrudes from the outer periphery of the clamping part and extends outward; a locking part is formed on the inner periphery of the mating part and located between the extrusion part and the mating part, and the locking part is a contoured structure adapted to the locking ring.

Optionally, the outer periphery of the locking ring presents an alternatingly undulating outer wave-shaped structure, and the outer wave-shaped structure includes at least three circumferentially arranged outer valley portions; the outer valley portions are configured to be composed of at least one outer valley subset, each outer valley subset includes a pair of adjacently arranged outer valley portions, and the corresponding pair of outer valley portions in each outer valley subset defines an outer peak portion located therebetween; the outer peak portion has an outer diameter larger than that of the outer valley portion.

Optionally, each of the upper clearance grooves at least partially extends into the locking ring and divides the locking ring into at least two locking units at a corresponding outer peak.

Optionally, there is a smooth transition between the outer valley portion and the adjacent outer peak portion.

Optionally, the inner circumference of the locking portion presents an alternatingly undulating inner wave-shaped structure, and the inner wave-shaped structure includes at least three circumferentially arranged inner valley portions; the inner valley portion is configured to be composed of at least one inner valley subset, each inner valley subset includes a pair of adjacently arranged inner valley portions, and the corresponding pair of inner valley portions in each inner valley subset defines an inner peak portion located therebetween; the inner peak portion has an inner diameter larger than that of the inner valley portion.

Optionally, there is a smooth transition between the inner valley portion and the adjacent inner peak portion.

Optionally, the locking portion can rotate relative to the locking ring so that the locking ring switches between a released state and a clamped state; when the locking ring is in the released state, each outer valley portion is aligned with a corresponding inner valley portion, and each outer peak portion is aligned with a corresponding inner peak portion; when the locking ring is in the clamped state, each outer valley portion is aligned with a corresponding inner peak portion, and each outer peak portion is aligned with and conflicts with a corresponding inner valley portion.

It is further found in practice that, although when the locking ring is in the clamping state, each outer peak is aligned with and in conflict with a corresponding inner valley, so that the locking ring can further clamp the lamp pole clamped in the clamping cavity when receiving radial pressure, however, due to the smooth fit between the locking ring and the locking portion, the clamping state of the locking ring cannot be stably maintained, and it is easy to get out of the clamping state when subjected to any circumferential disturbance, so that the lamp pole cannot be further clamped. To solve this problem, the sealing installation structure of the smart street lamp pole for the Internet of Things is further improved: each of the upper clearance grooves extends into the locking ring and penetrates the locking ring at a corresponding outer peak, so that at least two limit grooves connected to the upper clearance grooves are formed on the outer periphery of the locking ring; during the rotation of the locking portion, the inner valley is at least partially immersed in the limit groove and its rotation trend is limited by the limit groove and terminated. Thereby, the clamping state of the locking ring can be maintained to a certain extent. At this time, to switch the locking ring from the clamping state to the releasing state, a slightly larger tangential force needs to be applied to the locking portion so that the inner valley portion passes over the tip of the corresponding limiting groove.

One of the above technical solutions has the following advantages or beneficial effects: in practice, in order to facilitate the insertion of the lamp pole into the clamping piece, the inner diameter of the clamping cavity of the clamping piece is often slightly larger than the outer diameter of the lamp pole, so that there is an adjustment gap between the clamping cavity and the lamp pole during the assembly process. However, after the assembly is completed, the existence of the adjustment gap will also lead to unstable installation of the lamp pole and poor sealing performance. In this solution, since the outer periphery of the clamping piece can be elastically deformed after being subjected to radial pressure, the clamping piece can shrink radially to switch from a loose state to a clamping state, so that when the clamping piece is in a loose state, it is convenient to insert and assemble the lamp pole. After the assembly is completed, the clamping piece is adjusted to the clamping state to eliminate the adjustment gap between the lamp pole and the clamping cavity, thereby improving the installation stability of the lamp pole and further improving the waterproof sealing, which can meet the waterproof sealing requirements of long-term outdoor installation.

Another technical solution among the above technical solutions has the following advantages or beneficial effects: since during the rotation of the locking portion, the inner valley portion is at least partially sunk into the limiting groove and its rotation tendency is restricted by the limiting groove and terminated, thereby preventing the mating part from loosening during long-term mating with the mounting base and the clamping part, and further preventing the unstable installation of the lamp pole and the broken seal.

Another technical solution among the above technical solutions has the following advantages or beneficial effects: due to the setting of the limit groove, the clamping state of the locking ring can be maintained to a certain extent. At this time, to switch the locking ring from the clamping state to the release state, it is necessary to apply a slightly larger tangential force to the locking part so that the inner valley portion passes over the tip of the corresponding limit groove, so that the clamping state of the locking ring can be stably maintained to a certain extent.

Example 1

FIG. 1 to FIG. 4 show an embodiment 1 of the present invention. In combination with FIG. 1 to FIG. 2 , it can be seen that the sealing installation structure 1 of the smart street lamp pole for the Internet of Things includes:

A mounting base 11 defining a mounting cavity 112, wherein the top of the mounting base 11 is open to form a mounting opening 111 communicating with the mounting cavity 112;

A holding member 13 defining a holding cavity 139, which has a docking section 137 at least partially connected to the mounting cavity 112 through the mounting opening 111 and a holding section 135 exposed from the mounting opening 111; and

A mating member 12 surrounding at least a portion of the fastening member 13 and the mounting base 11 and defining a mating cavity 124, comprising an extrusion portion 121 surrounding at least a portion of the holding section 135 and a mating portion 125 detachably surrounding at least a portion of the mounting base 11;

The outer diameter of the clamping section 135 is in the shape of a truncated cone which gradually increases from top to bottom, and the inner periphery of the extrusion portion 121 is formed with an extrusion surface 1211 which matches the outer periphery of the clamping section 135; at least two upper clearance grooves 133 and at least two lower clearance grooves 134 are radially arranged in the circumferential direction of the clamping member 13; the upper clearance grooves 133 extend downward from the upper opening 131 of the clamping member 13 and penetrate the inner and outer side walls of the clamping member 13, and the lower clearance grooves 134 extend from the lower opening 131 of the clamping member 13 to the inner and outer side walls of the clamping member 13; The opening 132 extends upward and penetrates the inner and outer side walls of the clamping member 13, so that when the outer periphery of the clamping member 13 is subjected to radial compressive force, it can be elastically deformed, so that the clamping member 13 contracts radially to switch from a loose state to a clamped state; the mating member 12 can slide up and down relative to the mounting base 11 to switch between a locked state and an unlocked state, and when the mating member 12 slides downward relative to the mounting base 11, the extrusion surface 1211 continuously applies the radial compressive force to the outer periphery of the clamping member 13.

In practice, in order to facilitate the insertion of the lamp pole into the clamping piece, the inner diameter of the clamping cavity of the clamping piece is often slightly larger than the outer diameter of the lamp pole, so that there is an adjustment gap between the clamping cavity and the lamp pole during the assembly process. However, after the assembly is completed, the existence of the adjustment gap will also lead to unstable installation of the lamp pole and poor sealing performance. In the present solution, since the outer periphery of the clamping piece can be elastically deformed after being subjected to radial pressure, the clamping piece can shrink radially to switch from a loose state to a clamping state, so that the lamp pole can be easily inserted and assembled when the clamping piece is in the loose state. After the assembly is completed, the clamping piece is adjusted to the clamping state to eliminate the adjustment gap between the lamp pole and the clamping cavity, thereby improving the installation stability of the lamp pole and further improving the waterproof sealing, which can meet the waterproof sealing requirements of long-term outdoor installation.

Referring to Figure 2, the upper give-way groove 133 is configured to be composed of at least one give-way subset, each give-way subset includes a pair of upper give-way grooves 133 arranged adjacent to each other, the corresponding pair of upper give-way grooves 133 in each give-way subset are spaced apart from each other to form a spacing space therebetween, and the corresponding spacing space in each give-way subset is aligned with a corresponding one of the lower give-way grooves 134. Thereby, when the extrusion surface 1211 continuously applies the radial compressive force to the outer periphery of the clamping member 13, the side wall of the clamping section 135 can rotate inwardly around the root of the upper giveway groove 133 so as to realize the radial contraction of the clamping section 135 and thus clamp the lamp pole, and at the same time, the side wall of the docking section 137 can rotate inwardly around the root of the lower giveway groove 134 so as to realize the radial contraction of the docking section 137 and thus clamp the lamp pole. In addition, since the corresponding interval space in each giveway subset is aligned with a corresponding lower giveway groove 134, that is, the upper giveway groove 133 is neither connected to nor aligned with the lower giveway groove 137, the structure of the clamping member is prevented from being damaged due to the expansion and extension of the upper giveway groove 133 and/or the lower giveway groove 137 during the radial contraction of the clamping member, thereby improving the durability of the clamping member.

In practice, it is found that the mating parts are prone to loosening during the long-term cooperation with the mounting base and the fastening parts, which leads to unstable installation of the lamp pole and broken seal. To solve this problem, the sealing installation structure of the smart street lamp pole for the Internet of Things has been further improved:

2 and 3 , a locking ring 136 is formed on the outer periphery of the fastening member 13 and is located between the docking section 137 and the clamping section 135 , and the locking ring 136 protrudes from the outer periphery of the fastening member 13 and extends outward; a locking portion 122 is formed on the inner periphery of the mating member 12 and is located between the extrusion portion 121 and the mating portion 125 , and the locking portion 122 is a contoured structure adapted to the locking ring 136 .

As a further improvement, the outer periphery of the locking ring 136 presents an alternating undulating outer wave-shaped structure, and the outer wave-shaped structure includes at least three circumferentially arranged outer valley portions 1361; the outer valley portions 1361 are configured to be composed of at least one outer valley subset, each outer valley subset includes a pair of adjacently arranged outer valley portions 1361, and the corresponding pair of outer valley portions 1361 in each outer valley subset is defined to form an outer peak portion 1362 located therebetween; the outer peak portion 1362 has an outer diameter larger than that of the outer valley portion 1361.

As a further improvement, referring to FIG. 3 and FIG. 4 , each of the upper clearance grooves 133 at least partially extends into the locking ring 136 and divides the locking ring 136 into at least two locking units at a corresponding outer peak 1362 .

As a further improvement, the outer valley portion 1361 and the adjacent outer peak portion 1362 have a smooth transition.

As a further improvement, the inner circumference of the locking portion 122 is an alternatingly undulating inner wave-shaped structure, and the inner wave-shaped structure includes at least three circumferentially arranged inner valley portions 1221; the inner valley portions 1221 are configured to be composed of at least one inner valley subset, each inner valley subset includes a pair of adjacent inner valley portions 1221, and the corresponding pair of inner valley portions 1221 in each inner valley subset is defined to form an inner peak portion 1222 located therebetween; the inner peak portion 1222 has an inner diameter larger than that of the inner valley portion 1221.

As a further improvement, referring to FIG. 4 and FIG. 5 , the inner valley portion 1221 and the adjacent inner peak portion 1222 have a smooth transition.

Referring again to FIG. 3 and FIG. 4 , the locking portion 122 can rotate relative to the locking ring 136 so that the locking ring 136 switches between a release state and a clamping state; when the locking ring 136 is in a release state, each outer valley portion 1361 is aligned with a corresponding inner valley portion 1221, and each outer peak portion 1362 is aligned with a corresponding inner peak portion 1222; when the locking ring 136 is in a clamping state, each outer valley portion 1361 is aligned with a corresponding inner peak portion 1222, and each outer peak portion 1362 is aligned with and conflicts with a corresponding inner valley portion 1221. Therefore, when the locking ring 136 is in a clamping state, since each outer peak portion 1362 is aligned with and conflicts with a corresponding inner valley portion 1221, the locking ring 136 will further clamp the lamp pole clamped in the clamping cavity when receiving a radial pressure force, further improving the installation stability and waterproof sealing performance of the lamp pole. In a preferred embodiment, the mating portion 125 is threadedly connected to achieve a detachable connection with the mounting base 11, so that during the screwing-in process, the mating piece 12 can not only descend relative to the mounting base 11, but also enable the extrusion surface 1211 to continuously apply the radial compressive force to the outer periphery of the clamping section 135 of the clamping piece 13 during the descending process, thereby forcing the clamping piece 13 to radially clamp the lamp pole inserted therein, and after the screwing-in to a certain extent, the mating piece 13 is continued to be rotated so that each outer peak portion 1362 is aligned with and contacts with a corresponding inner valley portion 1221, so that the lamp pole can be further clamped, thereby further improving the installation stability and waterproof sealing.

In practice, it is further found that, although when the locking ring 136 is in the clamping state, each outer peak 1362 is aligned with and conflicts with a corresponding inner valley 1221, so that the locking ring 136 can further clamp the lamp pole clamped in the clamping cavity when receiving radial pressure, however, due to the smooth fit between the locking ring 136 and the locking portion 122, the clamping state of the locking ring 136 cannot be stably maintained, and it is easy to be out of the clamping state by any circumferential disturbance, so that the lamp pole cannot be further clamped. In order to solve this problem, the sealing installation structure of the smart street lamp pole for the Internet of Things is further improved: each of the upper give way grooves 133 extends to the locking ring 1 36 and penetrates the locking ring 136 at a corresponding outer peak 1362 so that at least two limiting grooves 1363 connected to the upper giving way groove 133 are formed on the outer periphery of the locking ring 136; during the rotation of the locking portion 122, the inner valley portion 1221 is at least partially immersed in the limiting groove 1363 and its rotation trend is restricted by the limiting groove 1363 and terminated, so that the clamping state of the locking ring 136 can be maintained to a certain extent. At this time, in order to switch the locking ring 136 from the clamping state to the release state, it is necessary to apply a slightly larger tangential force to the locking portion 122 so that the inner valley portion 1221 passes over the tip of the corresponding limiting groove 1363.

Example 2

FIG. 1 and FIG. 2 also show Embodiment 2 of the present invention. The difference between Embodiment 2 and Embodiment 1 is that:

In the loosened state, the inner diameter of the holding cavity 139 is larger than the outer diameter of the lamp pole, and a distance is provided between the bottom of the upper clearance groove 133 and the top of the lower clearance groove 134 to form a sealing area, in which at least one inner sealing ring 138 is arranged axially. The inner sealing ring 138 is at least partially made of a soft and/or flexible material, so that the inner sealing ring 138 can seal the inserted lamp pole. For example, the inner sealing ring 138 can be made of, but not limited to, rubber and/or rubber-like materials, or, as long as the inner sealing ring 138 performs the functions described herein, it can be of any structure.

Example 3

FIG. 1 and FIG. 2 also show embodiment 3 of the present invention. The difference between embodiment 3 and embodiment 1/embodiment 2 is that:

A first sealed space 123 is formed between the lower surface of the locking ring 136 and the end of the installation opening 111, and a first sealing ring 123 is disposed in the first sealed space 123. The first sealing ring 123 is at least partially made of a soft and/or flexible material, so that the first sealing ring 123 can seal between the lower surface of the locking ring 136 and the end of the installation opening 111. For example, the first sealing ring 123 can be made of, but not limited to, rubber and/or rubber-like materials, or, as long as the first sealing ring 123 performs the functions described herein, it can be of any structure.

Example 4

FIG. 1 and FIG. 2 also show Embodiment 4 of the present invention. The difference between Embodiment 4 and Embodiment 1/Embodiment 2/Embodiment 3 is that:

The inner diameter of the installation cavity 112 is the same as or slightly larger than the outer diameter of the lamp post, and the inner diameter of the installation opening 111 is the same as or slightly larger than the outer diameter of the docking section 137 in the loose state, so that a shoulder 1111 is formed between the bottom of the installation opening 111 and the top of the installation cavity 112, and a sealing gasket 113 is embedded in the shoulder 1111, and a second sealing ring 114 is provided between the sealing gasket 113, the bottom of the docking section 137, and the inner side wall of the installation opening 111. The second sealing ring 114 is at least partially made of a soft and/or flexible material, so that the second sealing ring 114 can seal the sealing gasket 113, the bottom of the docking section 137, and the inner side wall of the installation opening 111. For example, the second sealing ring 114 can be made of, but not limited to, rubber and/or rubber-like materials, or, as long as the second sealing ring 114 performs the functions described herein, it can be of any structure.

In the embodiment shown in Figure 2, the outer periphery of the sealing gasket 113 is formed with a lower sealing slope 1131 that gradually expands outward from top to bottom, the bottom outer periphery of the docking section 137 is formed with an upper sealing slope 1371 that gradually contracts from top to bottom, and the second sealing ring 114 is arranged between the upper sealing slope 1371, the lower sealing slope 1131 and the inner side wall of the installation port 111.

In the embodiment shown in FIG. 2 , a counterweight base 116 is integrally formed at the bottom of the mounting base 11 . The outer diameter of the counterweight base 116 is greater than the outer diameter of the mounting base 11 so that a limiting shoulder 1161 is formed therebetween.

Example 5

FIG1 also shows Embodiment 5 of the present invention. Embodiment 5 differs from Embodiment 1/Embodiment 2/Embodiment 3/Embodiment 4 in that:

A guide sealing strip 1351 is provided on the outer periphery of the clamping section 135 and is arranged on both sides of the upper give way groove 133. The guide sealing strip 1351 starts from the top of the clamping section 135 and extends downward along the side of the clamping section 135 to a corresponding outer valley portion 1361. When the extrusion portion 121 is fitted onto the clamping section 135, the guide sealing strip 1351 fits tightly with the inner periphery of the extrusion portion 121, so that liquids such as water can flow into the first sealed space 123 through the outer valley portion 1361 under the guidance of the guide sealing strip 1351. At the same time, a drainage hole leading to the outside can be opened in the first sealed space 123 so that liquids such as water can be discharged.

Example 6

FIG5 also shows Example 6 of the present invention. The difference between Example 6 and Example 1/Example 2/Example 3/Example 4/Example 5 is that:

At least part of the tip of the inner valley portion 1221 is rotatably connected with a guide wheel 1223, and at least part of the outer peripheral surface of the guide wheel 1223 protrudes from the tip of the inner valley portion 1221, so that not only the friction between the inner valley portion 1221 and the outer valley portion 1361 is transformed from sliding friction to rolling friction, thereby improving the smoothness of the adjustment of the matching member 12, but also during the rotation of the locking portion 122, when the inner valley portion 1221 is at least partially immersed in the limiting groove 1363, the exposed part of the guide wheel 1223 is just matched to the limiting groove 1363. In the position groove 1363, the rotation tendency of the locking part 122 is limited by the position groove 1363 and terminated, so that the clamping state of the locking ring 136 can be maintained to a certain extent. At this time, to switch the locking ring 136 from the clamping state to the release state, it is necessary to apply a slightly larger tangential force to the locking part 122 so that the inner valley part 1221 passes over the tip of the corresponding position groove 1363. The existence of the guide wheel 1223 can prevent the position groove 1363 from being worn out prematurely due to sliding friction, resulting in the premature loss or loss of its position limiting ability. In the embodiment shown in Figure 5, the guide wheel 1223 is rotatably connected to the inner valley part 1221 through the rotating shaft 1223'.
