Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in fig. 1, a cable protection and guide device 10 according to an embodiment of the present invention is shown, in which the cable protection and guide device 10 is formed by overlapping and rotatably connecting a plurality of link plates 100 in sequence. Referring to fig. 2 and 3, each link plate 100 includes: a plate body 110 and a side plate 120. The plate body 110 is provided at both ends thereof with coupling pins 111 and coupling holes 112, respectively. The side plates 120 are connected to two sides of the plate body 110, a cable accommodating space 130 is formed between the plate body 110 and the two side plates 120, the side plates 120 are inclined relative to the plate body 110, and an included angle between the side plates 120 and the plate body 110 is an obtuse angle. Wherein the connecting pin 111 of any one link plate 100 is relatively rotatably connected with the connecting hole 112 of another adjacent link plate 100.
It is understood that the side plates 120 are positioned at both sides of the plate body 110, and serve to support the plate body 110. As shown in fig. 3, the side plate 120 is inclined with respect to the plate body 110, and an included angle between the side plate 120 and the plate body 110 is an obtuse angle, the side plates 120 on both sides are inclined in a direction away from each other from the plate body 110 to the placing plane, so that when the link plate 100 is placed on the placing plane, an inclined side plate 120 exists between the plate body 110 and the placing plane, so that a vehicle or a person who needs to pass through the link plate 100 can get on the plate body 110 from the side plate 120 and slide to the placing plane from the side plate 120 on the other side, and difficulty in crossing the link plate 100 is reduced.
Referring to fig. 2 and 3, a supporting plate parallel to the plate body 110 may be connected to one end of the side plate 120 contacting the placing plane, and a plurality of reinforcing plates are connected between the supporting plate and the side plate 120 to increase the strength of the side plate 120, so as to prevent the side plate 120 from being broken due to excessive weight bearing of the link plate 100 in the process of protecting the cable a, so that the cable a cannot be protected. The side plate 120 may have a plurality of opening grooves uniformly distributed therein, and the opening grooves are located in the gap between the side plate 120 and the plurality of reinforcing plates. The grooves are opened to reduce the molding difficulty of the side plate 120, so that the wall thickness of the side plate 120 is uniform in the molding process.
It is understood that the cable receiving space 130 serves to store the cable a such that the cable a is interposed between the placing plane and the link plate 100 and is covered by the plate body 110 and the side plates 120, thereby serving to protect the cable a. The cable a is laid in the cable housing space 130 in the same direction as the extending direction of the plate body 110 toward both ends where the connection pins 111 and the connection holes 112 are provided.
It is understood that the respective link plates 100 are identical in structure, and the coupling pin 111 of any one link plate 100 is relatively rotatably coupled with the coupling hole 112 of another adjacent link plate 100. That is, the connection pin 111 may be inserted into the connection hole 112 and be rotatably engaged with the connection hole 112. Preferably, the hole diameter of the connection hole 112 and the shaft diameter of the connection pin 111 are equal.
It is understood that any two connected link plates 100 may be connected in a straight state or a bent state as shown in fig. 1. Here, the straight state and the bent state refer to states of the cable a stored in the cable storage space 130, and states represented between the two link plates 100 may correspond to the straight state and the broken state, respectively.
It is understood that the coupling holes 112 and the coupling pins 111 have central axes perpendicular to the plate body 110 and are respectively located at both ends of the plate body 110. Preferably, referring to fig. 4, the central axes of the connecting hole 112 and the connecting pin 111 are on a central symmetrical section, the central symmetrical section is perpendicular to the plane of the plate body 110, and the two side plates 120 are symmetrically disposed on two sides of the central symmetrical section.
In the above solution, the two ends of the link plates 100 are respectively provided with the connecting pin 111 and the connecting hole 112 to realize that the adjacent link plates 100 can be relatively rotatably connected, so that the cable protection and guide device 10 formed by sequentially connecting a plurality of link plates 100 can be applied to the bending state of the cable a to be applied to corners and corners, thereby reducing the dead angle of the cable a and ensuring the safe operation of the cable a to a greater extent.
Referring to fig. 2 and 3, in a specific arrangement, one end of the plate body 110, at which the connecting pin 111 is disposed, is in an arc-shaped structure with a radius of R1 and is concentric with the connecting pin 111, a first circular groove 113 with a radius of R3 and concentric with the connecting hole 112 is formed on one end surface of the plate body 110, at which the connecting hole 112 is disposed, and R3 is greater than or equal to R1.
It is understood that the first circular groove 113 may be opened on the upper surface of the plate body 110, or may be opened on the lower surface of the plate body 110. Referring to fig. 3, when the first circular groove 113 is opened on the upper surface of the plate body 110, the connecting pin 111 of another link plate 100 may be inserted into the connecting hole 112 from the upper surface of the plate body 110 to the bottom, and when the connecting pin 111 is inserted into the connecting hole 112, the plate body 110 of another link plate 100 is located above the plate body 110. When the first circular groove 113 is opened at the lower surface, the connecting pin 111 of the other link plate 100 may be inserted into the connecting hole 112 from the lower surface of the plate body 110 from the bottom up, and when the connecting pin 111 is inserted into the connecting hole 112, the plate body 110 of the other link plate 100 is located below the plate body 110.
As shown in fig. 2, 3 and 4, when two adjacent link plates 100 are connected, the connecting pin 111 of the other link plate 100 is inserted into the connecting hole 112, and at this time, the first circular groove 113 functions to place the end of the plate body 110 of the other link plate 100, at which the connecting pin 111 is disposed, in the first circular groove 113, to reduce a height difference caused when the two adjacent connecting plates are connected.
It will be appreciated that the end of the plate body 110 of the other link plate 100, at which the connecting pin 111 is disposed, is also positioned in the first circular groove 113 to ensure that the connecting pin 111 and the connecting hole 112 can be rotated with each other without being restricted by the non-grooved portion of the plate body 110. Therefore, R3 is not less than R1. Preferably, R3 is equal to R1, so that when two adjacent link plates 100 are connected, the side wall of the first circular groove 113 with the radius R3 is in contact with the circular arc-shaped structure with the radius R1 at the end of the plate body 110 of the other link plate 100 where the connecting pin 111 is provided, thereby limiting the plate body 110 of the other link plate 100 to a certain extent and reducing the wobbling between the two link plates 100 even if the connecting pin 111 and the connecting hole 112 are in clearance fit.
It is understood that, for convenience of processing, the connection between the side wall of the first circular groove 113 and the side plates 120 at both sides may be provided with a transition arc.
By forming the first circular groove 113 on the surface of the plate body 110 at the end where the connecting hole 112 is formed, when two adjacent link plates 100 are connected, the end of the plate body 110 of another link plate 100 where the connecting pin 111 is formed is disposed in the first circular groove 113, so as to reduce the height difference caused when two adjacent link plates are connected.
With reference to fig. 2, fig. 3 and fig. 4, in a specific installation manner, an end of the plate body 110 where the connection hole 112 is disposed is in an arc-shaped structure with a radius of R2 and concentric with the connection hole 112, an end surface of the plate body 110 where the connection pin 111 is disposed is provided with a second circular groove 114 with a radius of R4 and concentric with the connection pin 111, and R4 is greater than or equal to R2.
It is understood that the second circular groove 114 may be formed on the upper surface of the plate body 110, or may be formed on the lower surface of the plate body 110. When the second circular groove 114 is opened on the upper surface of the plate body 110, the connecting pin 111 may be inserted into the connecting hole 112 from the bottom to the top of the lower surface of the plate body 110 of the other link plate 100, and when the connecting pin 111 is inserted into the inside of the connecting hole 112, the plate body 110 of the other link plate 100 is located above the plate body 110. Referring to fig. 4, when the second circular groove 114 is opened on the lower surface of the plate body 110, the connecting pin 111 may be inserted into the connecting hole 112 from the top to the bottom of the upper surface of the plate body 110 of another link plate 100, and when the connecting pin 111 is inserted into the connecting hole 112, the plate body 110 of another link plate 100 is located below the plate body 110.
As shown in fig. 2, 3 and 4, when two adjacent link plates 100 are connected, the connection pin 111 is inserted into the connection hole 112 of the other link plate 100, and at this time, the second circular groove 114 functions to place the end of the plate body 110 of the other link plate 100, at which the connection hole 112 is provided, in the second circular groove 114, to reduce a height difference caused when the two adjacent link plates are connected.
It will be appreciated that the end of the plate body 110 of the other link plate 100, at which the coupling hole 112 is provided, is also positioned in the second circular groove 114 to ensure that the coupling pin 111 and the coupling hole 112 can be rotated with each other without being restricted by the non-grooved portion of the plate body 110. Therefore, R4 is not less than R2. Preferably, R4 is equal to R2, so that when two adjacent link plates 100 are connected, the side wall of the second circular groove 114 with the radius R4 is abutted against the circular arc-shaped structure with the radius R2 at the end of the plate body 110 of the other link plate 100 where the connecting hole 112 is provided, thereby limiting the plate body 110 of the other link plate 100 to a certain extent, and reducing the wobbling between the two link plates 100 even if the connecting pin 111 and the connecting hole 112 are in clearance fit.
It is understood that, for convenience of processing, the junction between the side wall of the second circular groove 114 and the side plates 120 on both sides may be provided with a transition arc.
By forming the second circular groove 114 on the surface of one end of the plate body 110 where the connecting pin 111 is provided, when two adjacent link plates 100 are connected, the end of the plate body 110 of another link plate 100 where the connecting hole 112 is provided is placed in the second circular groove 114, so as to reduce the height difference caused when two adjacent link plates are connected.
Referring to fig. 4, in a specific configuration, the first circular groove 113 and the second circular groove 114 are alternatively located on two opposite surfaces of the plate body 110, and the depth of the first circular groove 113 and the depth of the second circular groove 114 are equal to the thickness of the plate body 110.
Specifically, as shown in fig. 4, when the first circular groove 113 is located on the upper surface of the plate body 110, the second circular groove 114 is disposed on the lower surface of the plate body 110, so that the first circular groove 113 and the second circular groove 114 can simultaneously play a role in reducing a height difference caused when two adjacent connecting plates are connected.
When the depth of the first circular groove 113 and the second circular groove 114 is equal to the thickness of the plate body 110, when two adjacent link plates 100 are connected, the depth of the first circular groove 113 and the second circular groove 114 can reduce the thickness of the two plate bodies 110 stacked to be consistent with the thickness of a single plate body 110, so that when two adjacent link plates 100 are connected, the plate bodies 110 of the two link plates 100 can be kept horizontal and consistent in height, and the inclination of the plate bodies 110 caused by the height inconsistency when a plurality of link plates 100 are connected is avoided.
It is understood that one end of the plate body 110, at which the connection pin 111 is disposed, has a circular arc-shaped structure with a radius of R1 concentric with the connection pin 111, and one end of the plate body 110, at which the connection hole 112 is disposed, has a circular arc-shaped structure with a radius of R2 concentric with the connection hole 112. The arc-shaped structure with the radius of R1 and the arc-shaped structure with the radius of R2 are respectively disposed at two ends of the plate body 110, and respectively matched with the first circular groove 113 and the second circular groove 114, but the two are not directly matched. However, when the difference between R1 and R2 is large, when two link plates 100 are connected, the first circular groove 113 or the second circular groove 114 will have a large area not to be matched with another link plate 100, thereby creating a large area on the surface of the plate body 110 not flush with the plate body 110 of the non-grooved portion, which may affect other objects passing through the surface of the plate body 110. Thus, in one particular arrangement, R1 ═ R2.
Referring to fig. 2 to 5, in a specific arrangement, the plate body 110 is provided with a plurality of limiting holes 115, and the limiting holes 115 are uniformly distributed in a concentric circle shape along the connecting pin 111 or the connecting hole 112.
Limiting holes 115 are formed around the connecting pin 111 and the connecting hole 112. The plurality of stopper holes 115 are uniformly distributed in the circumferential direction concentrically along the connecting pin 111 or in the circumferential direction concentrically along the connecting hole 112. When the direction in which two adjacent link plates 100 are coupled is fixed, the same stopper pin may pass through the stopper hole 115 around the coupling pin 111 and the stopper hole 115 around the coupling hole 112 of the other link plate 100, so that the two coupled link plates 100 are not rotated with each other.
It can be understood that the greater the number of the position-limiting holes 115, the more precise the angle at which the two connected link plates 100 can be fixed after being rotated. As shown in fig. 5, the number of the connection holes 112 and the stopper holes 115 around the connection pin 111 may be set to 12, and the angle between each adjacent stopper holes 115 may be 30 degrees.
Referring to fig. 2, in a specific arrangement, a partition plate 140 is connected to a bottom surface of the plate body 110, and the cable accommodation space 130 is uniformly divided by the partition plate 140.
It is understood that the partition plate 140 is interposed between the plate body 110 and the placement plane, which uniformly divides the cable housing space 130 so that a plurality of sets of cables a can be organized to pass through small spaces in the cable housing space 130. The number of the partition plates 140 is not fixed, and may be set to be single or plural according to the requirement. Referring to fig. 2, in the present embodiment, the number of the partitions 140 is two, and the two partitions 140 divide the cable accommodation space 130 into three small spaces uniformly.
It is understood that the partition plate 140 is interposed between the plate body 110 and the placing plane, and it may also serve as a support for the plate body 110, which may increase the strength of the plate body 110 to some extent. Thus, in one particular arrangement, the link plate 100 is of a flexible material. The link plate 100 may be made of flexible material such as plastic, rubber, etc.
Referring to fig. 5, in a specific arrangement, the two side plates 120 are provided with inclined edges 121 at ends close to the connecting pin 111, and the outer end faces of the inclined edges 121 are located on a plane passing through the central axis of the connecting pin 111.
It can be understood that the angle at which the two link plates 100 can be relatively turned is subject to the maximum width of the relative rotation center of the two link plates 100 when the adjacent link plates 100 are connected. The rotation centers of the two link plates 100 are central axes of the connection pins 111. The maximum width of the relative rotation center of the link plate 100 is controlled by the width and the inclination angle of the side plates 120.
It can be understood that, when the two link plates 100 are relatively rotated, the angle at which the side plates 120 at the inner sides of the two link plates 100 are abutted is the maximum angle at which the two link plates 100 can be relatively rotated. When the width and the inclination angle of the two side plates 120 are determined, one ends of the two side plates 120 near the connecting pin 111 may be set as the inclined sides 121 to increase the angle at which the two link plates 100 can be relatively rotated to a greater extent.
With continued reference to fig. 5, in a specific arrangement, the inclined sides 121 of the two side plates 120 are symmetrically arranged, and the angle between the planes of the outer end faces of the inclined sides 121 is 0-30 °.
It will be appreciated that when the angle between the planes of the outer end faces of the inclined edges 121 is 0 deg., the angle of rotation between the two side plates 120 is minimized. When the angle between the planes of the outer end faces of the oblique sides 121 is 30 °, the rotatable angle between the two side plates 120 is the largest, 120 ° as shown in fig. 5.
