The adsorption structure is used as a connecting device, is widely applied to fixing objects in daily life, and is fixed at a position preset by a user through the adsorption effect of the adsorption structure. Among them, when the user uses the adsorption structure to fix the object, the demand for the adsorption structure is diversified. The most common application of the adsorption structure is a sucker hook, and a sucker part is used for adsorbing a smooth wall or glass; another application is to fix a sucker, and the suction part of the sucker is used for sucking and fixing other objects.

In the prior art, when an object is fixed at a preset position of a user by an adsorption structure, the adsorption structure realizes a fixing effect by using natural adsorption; the natural adsorption realizes that the fixation is easily influenced by external force, so that the object is loosened, deviated or falls off relative to the adsorption structure, and particularly, when the adsorption surface is dirty, the object is more easily fallen under the action of the external force. In addition, under the condition of normal adsorption, when the user takes the object fixed on the adsorption structure down, the user is also required to overcome the adsorption effect of the adsorption structure, and the object is inconvenient to take down.

For solving the above-mentioned problem, this patent provides an adsorption structure, solves current adsorption structure and can not fix the object steadily and be not convenient for take off the object problem of being fixed in adsorption structure.

For the purpose of understanding, specific embodiments of the present embodiments are described below in detail with reference to the accompanying drawings.

Referring to fig. 1, as shown, an adsorbing member 100 is used for adsorbing other objects; the absorption member 100 forms a first cavity 110 with an opening, and the opening of the first cavity 110 is used for forming a sealing structure with the surface of other objects; a negative pressure mechanism 200, the negative pressure mechanism 200 having a second cavity 210 for generating negative pressure, the second cavity 210 being in communication with the first cavity 110; an actuating mechanism 300 for actuating the negative pressure mechanism 200; a release mechanism 400 for balancing the pressure in the first chamber 110 with the atmospheric pressure, so that the adsorbing member 100 releases the adsorbed object.

In this embodiment, the adsorbing member 100 is used for adsorbing other objects; the absorption member 100 forms a first cavity 110 with an opening, and the opening of the first cavity 110 is used for forming a sealing structure with the surface of other objects; a negative pressure mechanism 200, the negative pressure mechanism 200 having a second cavity 210 for generating negative pressure, the second cavity 210 being in communication with the first cavity 110; an actuating mechanism 300 for actuating the negative pressure mechanism 200; a release mechanism 400 for balancing the pressure in the first chamber 110 with the atmospheric pressure, so that the adsorbing member 100 releases the adsorbed object. The negative pressure mechanism 200 generates negative pressure through the second cavity 210, so that the adsorption piece 100 generates negative pressure adsorption, and the negative pressure adsorption has better adsorption effect than natural adsorption; secondly, the adsorbing member 100 forms a first cavity 110 with an opening, and because the first cavity 110 forms a sealing structure with the surface of another object, the pressure and the atmospheric pressure of the first cavity 110 can be kept different from the external pressure and the atmospheric pressure, so that the adsorbing member 100 can be stably and stably adsorbed on the surface of another object; in addition, the second cavity 210 is communicated with the first cavity 110, and the negative pressure mechanism 200 can adjust the negative pressure adsorption strength of the adsorption member 100 by adjusting the negative pressure strength of the second cavity 210; the actuating mechanism 300 and the releasing mechanism 400 respectively control the absorption and release of the absorption structure, and a user can autonomously control the absorption and release of the absorption structure during use.

It should be noted that the adsorption element 100 and the common adsorption element 100 have different adsorption effects, so the structure of the adsorption element 100 is different from that of the common adsorption element 100, and the adsorption element 100 needs to satisfy the communication between the first cavity 110 and the second cavity 210, so as to achieve the negative pressure adsorption effect. The embodiment of the present application is not limited to the above-mentioned specific implementation of the suction member 100, and for the convenience of understanding, the embodiment of the present application provides two preferred implementations, including the first implementation in which the suction member 100 is the suction cup 120. In the second embodiment, the adsorbing member 100 is a sealing ring.

For the sake of understanding, the two modes are described in detail below with reference to the accompanying drawings.

First, the suction member 100 is a suction cup 120

Referring to fig. 1 and 6, as shown in the figure, the suction member 100 is configured as a suction cup 120, and a through hole 130 communicating with the second cavity 210 is formed at the bottom of the suction cup 120.

In this embodiment, the suction member 100 is configured as a suction cup 120, and a through hole 130 communicating with the second cavity 210 is formed at the bottom of the suction cup 120. The suction cup 120 is made of a flexible material, so that when the first cavity 110 and the surface of another object form a sealing structure, the sealing structure has good sealing performance, the pressure and the atmospheric pressure in the first cavity 110 are kept unchanged, and secondly, the suction cup 120 can be adsorbed on different contact surfaces, such as a spherical surface and a concave surface; the bottom of the suction cup 120 forms a through hole 130 communicated with the second cavity 210, so that the adsorption effect of the adsorption piece 100 is not affected, and meanwhile, the requirements of the first cavity 110 and the second cavity 210 can be met.

Second mode, the absorption member 100 is a sealing ring

Referring to fig. 1 and 6, as shown, the absorbing member 100 is a sealing ring (not shown), and a first cavity 110 is formed inside the sealing ring; the absorption structure is provided with a through hole 130 located inside the sealing ring, and the through hole 130 communicates the first cavity 110 and the second cavity 210.

The sealing ring is low in manufacturing cost, meanwhile, due to the elasticity of the sealing ring, when the adsorption piece 100 realizes negative pressure adsorption, the sealing ring is extruded by the adsorption structure and other objects, so that no gap exists between the adsorption piece 100 and the surfaces of the other objects, a sealing structure is formed between the first cavity 110 and the surfaces of the other objects, and meanwhile, the through hole 130 formed in the inner side of the sealing ring meets the requirement for communicating the first cavity 110 with the second cavity 210.

It should be noted that the adsorption member 100 of the adsorption structure generates a negative pressure adsorption effect, and is realized by communicating the first cavity 110 with the second cavity 210, and the second cavity 210 generates a negative pressure; there are various ways to generate negative pressure in the second cavity 210, for example, the inverter provides negative pressure, and the negative pressure power converter generates negative pressure; the embodiment of the present application is not limited to the specific implementation of the second cavity 210 for generating the negative pressure, and the embodiment of the present application provides a preferred implementation for understanding.

Referring to fig. 1, as shown, the negative pressure mechanism 200 includes a cylinder 220 and a driving mechanism 230 for driving the cylinder 220; the cylinder 220 is connected to the second chamber 210 to generate negative pressure in the second chamber 210 when the cylinder 220 is operated.

In the present embodiment, the negative pressure mechanism 200 includes a cylinder 220 and a driving mechanism 230 that drives the cylinder 220; the cylinder 220 is connected to the second chamber 210 to generate negative pressure in the second chamber 210 when the cylinder 220 is operated. The air cylinder 220 can generate negative pressure in the second chamber 210 under the driving of the driving mechanism 230, secondly, since the air cylinder 220 is driven by the driving mechanism 230 to work, a user can control whether the air cylinder 220 works or not by controlling the driving mechanism 230 to start or stop, so as to meet the requirements of different situations, and in addition, the air cylinder 220 has good sealing performance, so that the pressure of the first chamber 110 and the atmospheric pressure can be kept stable and unchanged when the extracted gas is stored in the air cylinder 220.

It should be noted that, there are various implementation manners of the driving manner of the driving mechanism 230, for example, manual driving, the structure of the air cylinder 220 needs to be matched with the driving manner of the driving mechanism 230, and meanwhile, the strength of the negative pressure generated by the driving mechanism 230 driving the air cylinder 220 to the second cavity 210 needs to reach the negative pressure strength required by the negative pressure adsorption effect, and the specific implementation manners of the driving mechanism 230 and the air cylinder 220 that meet the above requirements are not limited in this application embodiment, and this application embodiment provides a preferred implementation manner for facilitating understanding.

Referring to fig. 1, as shown in the figure, the driving mechanism 230 is configured as a motor 231, and an output rotating shaft of the motor 231 is connected with a crank 232; the cylinder 220 includes a cylinder body 221, a piston 222, and a piston rod 223; the crank 232 is used for connecting and driving the piston rod 223, so that when the negative pressure mechanism 200 works, the motor 231 drives the piston 222 to reciprocate through the crank 232, thereby pumping out the gas in the second chamber 210.

In this embodiment, the driving mechanism 230 is configured as a motor 231, and an output rotating shaft of the motor 231 is connected with a crank 232; the cylinder 220 includes a cylinder body 221, a piston 222, and a piston rod 223; the crank 232 is used for connecting and driving the piston rod 223, so that when the negative pressure mechanism 200 works, the motor 231 drives the piston 222 to reciprocate through the crank 232, thereby pumping out the gas in the second chamber 210. Adopt the motor 231 drive, can be through the working method who sets up motor 231 for cylinder 220 works as required in fact, thereby second cavity 210 stably produces the negative pressure that satisfies negative pressure intensity, and secondly, motor 231 drive does not need user's manual drive, and the user of being convenient for uses, and simultaneously, cylinder 220 adopts piston 222 and piston rod 223, can make cylinder 220 do piston 222 motion under the drive of actuating mechanism 230, so that second cavity 210 produces the negative pressure and can bear high-pressure atmospheric pressure.

Alternatively, there are various ways to realize the crank 232, for example, a connecting rod that is the same as the axial direction is arranged on the outer side surface of a disc connected with the rotating shaft of the motor 231, or a crankshaft formed by extending the rotating shaft of the motor 231 twice and bending the rotating shaft in opposite directions by 90 degrees, or a crank similar to a single-cylinder diesel engine, etc., as long as a structure that converts the circular motion of the rotation of the motor 231 into the reciprocating linear motion can be realized, which can be collectively referred to as the crank 232 in the present application.

It should be noted that, the starting mechanism 300 starts the negative pressure mechanism 200, so that the timing of the suction structure generating the negative pressure suction effect is freely determined by the user, and therefore, the starting mechanism 300 needs to be provided with a switch device, so that when the user needs to use the suction structure to generate the negative pressure suction effect, the starting mechanism 300 starts the negative pressure mechanism 200 to achieve the requirement. The switch-type device provided in the actuating mechanism 300 is not limited in the embodiments of the present application, and for convenience of understanding, the embodiments of the present application provide a preferred implementation.

Referring to fig. 1, as shown in the figure, the actuating mechanism 300 is configured as a mechanical switch 310, and the actuating portion 311 of the mechanical switch 310 is at least partially located outside the surface of the suction structure.

In this embodiment, the actuating mechanism 300 is configured as a mechanical switch 310, and the actuating portion 311 of the mechanical switch 310 is at least partially located outside the surface of the suction structure. The starting mechanism 300 is provided with a mechanical switch 310, so that the user can freely determine the time when the suction structure generates the negative pressure suction effect, and meanwhile, the action part 311 of the mechanical switch 310 is arranged on the surface, so that the user can conveniently operate the mechanical switch 310, and the mechanical switch 310 is conveniently matched with the suction piece 100.

It should be noted that, the user operates the mechanical switch 310 to activate the negative pressure mechanism 200, so that the adsorption structure generates the negative pressure adsorption effect, therefore, the mechanical switch 310 is a component that the user often operates when using the adsorption structure, and the user needs to simplify the way of using the component, so that when using the adsorption structure, the user only needs to contact the adsorption structure with another object tightly, and then the adsorption structure can be adsorbed to another object under the negative pressure. The embodiments of the present application are not limited to the specific implementation of simplifying the use of the mechanical switch 310, and provide a preferred implementation for understanding.

Referring to fig. 1, as shown in the figure, the action portion 311 of the mechanical switch 310 is located inside or beside the adsorbing member 100, and the action direction of the mechanical switch 310 is in the same direction as the opening of the adsorbing member 100, so that when the adsorbing structure is close to the adsorbed object, the action portion 311 is pressed by the adsorbed object to activate the negative pressure mechanism 200.

In this embodiment, the operation portion 311 of the mechanical switch 310 is located inside or beside the absorption member 100, and the operation direction of the mechanical switch 310 is in the same direction as the opening of the absorption member 100, so that when the absorption structure is close to the absorbed object, the operation portion 311 is pressed by the absorbed object to activate the negative pressure mechanism 200. The action part 311 of the mechanical switch 310 is located inside or beside the adsorption piece 100, and the action direction of the mechanical switch 310 is in the same direction as the opening of the adsorption piece 100, so that the negative pressure mechanism 200 can be started after the user tightly contacts the adsorption structure with other objects, the adsorption of the adsorption structure on other objects under negative pressure is realized, the user does not need to independently operate the mechanical switch 310, and the mode of using the mechanical switch 310 is simplified.

It should be noted that, in the adsorption process, the other objects to be adsorbed are loosened due to the external force, so that the adsorption structure needs to adsorb the other objects under negative pressure after being in close contact with the other objects, and when the other objects to be adsorbed are loosened in the adsorption process, the negative pressure mechanism 200 may be restarted to make the adsorption structure adsorb the other objects tightly. The embodiments of the present application are not limited to the specific implementation that meets the above requirements, and provide a preferred implementation for understanding.

Referring to fig. 1, as shown in the figure, the mechanical switch 310 is configured as a bidirectional start switch, and the mechanical switch 310 is used for turning on and starting the negative pressure mechanism 200 when the action part 311 is pressed and released, so as to automatically start the negative pressure mechanism 200 when the suction object is loosened.

In the present embodiment, the mechanical switch 310 is provided as a bidirectional activation switch, and the mechanical switch 310 is used to turn on and activate the negative pressure mechanism 200 when the action portion 311 is pressed and released, so as to automatically activate the negative pressure mechanism 200 when the suction object is loosened. The mechanical switch 310 is set as a bidirectional starting switch, and when the action part 311 is pressed or released, the negative pressure mechanism 200 is started, so when other objects to be adsorbed are loosened, the action part 311 of the mechanical switch 310 is released, and the negative pressure mechanism 200 is started, so that the adsorption structure can tightly adsorb other objects; therefore, the requirement that the adsorption structure is in close contact with other objects when the adsorption structure is required to adsorb other objects is met, the requirement that the adsorption structure is in loose contact with other adsorbed objects is met, the negative pressure mechanism 200 is automatically started to tightly adsorb other objects in the adsorption structure, and finally, before a user releases the adsorbed objects through the release mechanism 400, the adsorbed objects are stably and stably adsorbed on the adsorption structure.

It should be noted that, when the suction structure is in close contact with another object, the requirement for the mechanical switch 310 to start the negative pressure mechanism 200, and when the other object being sucked is loose, the requirement for the mechanical switch 310 to start the negative pressure mechanism 200 is realized by the action portion 311 of the mechanical switch 310 being pressed or released and cooperating with a component of the mechanical switch 310, and the specific implementation manner in which the action portion 311 of the mechanical switch 310 being pressed or released and cooperating with a component of the mechanical switch 310 to realize the requirement is not limited in this embodiment of the application.

The first embodiment.

Referring to fig. 2, as shown in the figure, the actuating portion 311 is provided with a rack 311a, and the mechanical switch 310 further includes a micro switch 313 and a gear 312 engaged with the rack 311 a; since the gear 312 is provided with a convex portion 312a on the circumference thereof, and the convex portion 312a is used to trigger the microswitch 313 when the operation portion 311 operates, so as to activate the negative pressure mechanism 200, the negative pressure mechanism 200 can be activated by the pressing of the convex portion 312a and the microswitch 313 when the gear 312 swings in both the forward and reverse directions.

In this embodiment, the operating portion 311 is provided with a rack 311a, and the mechanical switch 310 further includes a micro switch 313 and a gear 312 engaged with the rack 311 a; a convex portion 312a is provided on the periphery of the gear 312, and the convex portion 312a is used to trigger the microswitch 313 when the operation portion 311 operates, so as to activate the negative pressure mechanism 200. The rack 311a of the operating unit 311 drives the gear 312 engaged with the rack 311a to operate the gear 312; since the rack 311a and the gear 312 are used, when the operating part 311 is pressed or released, the convex part 312a on the circumference of the gear 312 moves to the micro switch 313, and the convex part 312a triggers the micro switch 313, so that when the suction structure is in close contact with other objects, the mechanical switch 310 starts the negative pressure mechanism 200, and when the other objects are loosened, the mechanical switch 310 also starts the negative pressure mechanism 200.

Example two.

In this embodiment, the mechanical switch 310 is a travel switch 314, and the travel switch 314 is used for activating the negative pressure mechanism 200 when the action portion 311 reaches a preset position. When the action part 311 moves to a specific position of a preset stroke, the stroke switch 314 starts the negative pressure mechanism 200, and meanwhile, the specific position is set on two reciprocating strokes of the action part 311, so that when the action part 311 moves to one specific position, the stroke switch 314 starts the negative pressure mechanism 200, and therefore when the adsorption structure is in close contact with other objects, the mechanical switch 310 starts the negative pressure mechanism 200, and when the adsorbed other objects are loosened, the mechanical switch 310 also starts the negative pressure mechanism 200.

In the process that the adsorption structure adsorbs other objects, the other objects continue to extrude the moving part which moves to the specific position, so that the moving part moves to the stroke end; when the moving part moves to the stroke end, the negative pressure mechanism 200 stops working.

It should be noted that, when the action part reaches the preset position, the mechanical switch is required to start the negative pressure mechanism, and when the action part does not reach the preset position, the mechanical switch is required to close the negative pressure mechanism; the embodiment of the present application is not limited to the specific implementation for achieving the above requirement, and for convenience of understanding, the embodiment of the present application provides a preferred implementation.
