The drag chain convenient for wire installation comprises a first side plate 10 and a second side plate 20 which are arranged at intervals, a first cover plate 30 and a second cover plate 40 which are connected between the first side plate 10 and the second side plate 20, and a first connecting mechanism 50 and a second connecting mechanism 60 which are respectively arranged between the first side plate 10 and the second side plate 20 and between the first cover plate 30 and the second cover plate 40. It is conceivable that a whole drag chain comprises a plurality of drag chains convenient for wire installation, each drag chain is connected with the adjacent drag chain through a rotating shaft, so that the adjacent drag chains can rotate to adapt to different application occasions and use states. Only one of the drag chains for facilitating the wire installation is taken as an example to illustrate the structure and the working principle.

The first side plate 10 and the second side plate 20 have the same structure and function, and only the first side plate 10 is taken as an example for description. The first side plate 10 includes a body 11, and two connecting plates 12 disposed at two ends of the body 11. The body 11 can be made of metal or plastic and has a plate-like structure, the size of which is set according to the actual needs, such as the size of the whole drag chain. The two connecting plates 12 are respectively used for connecting with adjacent drag chains, so that one of the two connecting plates 12 is provided with a through hole, and the other connecting plate is provided with a pivot. When a plurality of first side plates 10 are connected together, the pivot of one connecting plate 12 is inserted into the through hole of the other connecting plate 12, so that the rotary connection is realized. The first and second side plates 10 and 20 are spaced apart in parallel, so that the first and second cover plates 30 and 40 are disposed between the first and second side plates 10 and 20 and at both sides thereof, respectively.

The first and second cover plates 30, 40 also have the same structure and function, and only the first cover plate 30 is taken as an example for description. The first cover plate 30 is a plate-shaped structure and is disposed between two of the connecting plates 12 to prevent the first cover plate 30 from blocking two adjacent connecting plates 12 when they rotate. Since the first and second side plates 10 and 20 are disposed in parallel, the first and second cover plates 30 and 40 are also disposed in parallel.

The first connecting mechanism 50 is disposed between the first side plate 10 and the first cover plate 30, and likewise, it will be appreciated that the first connecting mechanism 50 is also disposed between the first side plate 10 and the second cover plate 40. Here, the structure and the operation principle of the first connecting mechanism 50 disposed between the first side plate 10 and the first cover plate 30 will be described by way of example only. The first connecting mechanism 50 includes a clamping structure 51 disposed on the first side plate 10, and a plug structure 52 disposed on the first cover plate 30. The first cover 30 and the first side plate 10 are fixedly connected by the first connecting mechanism 50. The clamping structure 51 comprises a clamping groove 511 arranged on the first side plate 10, two insertion blocks 512 arranged in the clamping groove 511 at intervals, and a clamping hook 513 arranged in the clamping groove 511. The engaging groove 511 is disposed between the two connecting plates 12, and the depth of the engaging groove along the arrangement direction of the first and second covers 30 and 40 is equal to the thickness of the first cover 30. Meanwhile, the width of the clamping groove 511 is equivalent to that of the first cover plate 30, so that when the first cover plate 30 is clamped into the clamping groove 511, a flush state can be achieved. The two insertion blocks 512 are arranged at intervals and at the bottom of the clamping groove 511, and the height thereof can be set according to actual needs, such as the size of the whole drag chain. The clamping hook 513 is also arranged at the bottom of the clamping groove 511 and is arranged at an interval with the two insertion blocks 512. The height of the clamping hook 513 is greater than that of the insert block 512, and the height is equivalent to the thickness of the first cover plate 30. The clamping hook 513 has a hook 514, and the hook 514 faces the insert block 512, but the whole clamping hook 513 is spaced from two insert blocks 512. The inserting structure 52 includes an inserting groove 521 disposed on the first cover 30, and a clamping hole 522 for clamping the clamping hook 513. The inserting groove 521 and the clamping hole 522 are arranged at intervals to respectively insert the inserting block 512 and the clamping hook 513. The clamping hole 522 is a step hole, namely a step, and when the clamping hook 513 is inserted into the clamping hole 522, the clamping hook 513 is hooked on the step of the clamping hole 522. The size of the snap hook 513 in the direction perpendicular to the arrangement direction of the first and second cover plates 30, 40 is equal to the minimum distance between the two insertion blocks 512, so that the snap hook 513 can be deformed back and forth, and the abutting force can be improved to the maximum extent. After the plug 512 is inserted into the insertion groove 521, it can provide a certain abutting force to prevent the clamping hook 513 from deforming when stressed, so as to improve the connection stability and strength between the first cover 30 and the first side plate 10.

The second connecting mechanism 60 is disposed between the second side plate 20 and the first cover plate 30, and likewise, it will be appreciated that the second connecting mechanism 60 is also disposed between the second side plate 20 and the second cover plate 40. Here, the structure and the operation principle of the second connecting mechanism 60 disposed between the second side plate 20 and the first cover plate 30 are only described as an example. The second connecting mechanism 60 includes a pivot structure 61 disposed on the second side plate 20, a pivot hole structure 62 disposed on the first cover plate 30, and a latch 63 for fixing the pivot structure 61 and the pivot structure 62. The rotating shaft structure 61 includes a mounting groove 611 disposed on the second side plate 20, two rotating shafts 612 disposed at intervals in the mounting groove 611, and a slot 613 disposed between the two rotating shafts 612. The structure and size of the mounting groove 611 are the same as those of the clamping groove 511, and the mounting groove 611 includes two opposite side walls 6111 and a bottom 6112 connected between the two side walls 6112. The two rotating shafts 612 are respectively disposed on the two side walls 6111 of the mounting groove 611 and spaced from the bottom 6112 of the mounting groove 611, so as to facilitate the insertion of the pivot structure 62 in the gap between the rotating shaft 612 and the bottom of the mounting groove 611. The arrangement direction of the two rotating shafts 612 is perpendicular to the arrangement direction of the first and second cover plates 30, 40 and the first and second side plates 10, 20. The slot 613 is disposed on the bottom 6112 of the mounting groove 611 and between the two rotating shafts 612. To improve fault tolerance, the slot 613 is a slot structure. The pivot structure 62 includes a semi-circular slot 621 passing through the shaft 612, and a through hole 622 passing through the semi-circular slot 621. The semicircular groove 621 faces away from the first and second side plates 10 and 20 along the opening direction of the radial opening, that is, the opening direction of the semicircular groove 621 and the first and second side plates 10 and 20 are respectively located at two sides of the first cover plate 30. Due to the semi-circular groove 621, the wall thickness of the semi-circular groove 621 is reduced, so that the gap between the rotating shaft 612 and the bottom of the mounting groove 611 can be inserted. In order to prevent the rotation shaft 612 from easily sliding out of the semi-circular groove 621, the central angle of the semi-circular groove 621 is greater than 180 degrees. Also, therefore, the semi-circular groove 621 has a leading edge to lead the shaft 612. The through hole 622 is formed along the radial direction of the semi-circular groove 621, i.e., penetrates through the semi-circular groove 621, and is aligned with the insertion groove 613, so as to facilitate the insertion of the pin 63. The latch 63 has a T-shaped structure, and includes a rod 631 inserted into the through hole 622 and the slot 613, and a cover 632 disposed at one end of the rod 631. In order to fix the relative position between the rod 631 and the through hole 622 and the slot 613, the rod 631 should be in interference fit with the through hole 622 and the slot 613. The plunger 631 is provided with two opposite depressions 633. When the latch 63 is inserted into the slot 613, the free ends of the two shafts 612 abut against the pits 633, so as to further fix the latch 63. Since the pin 63 is inserted into the through hole 622 of the semicircular groove 621 of the first cover 30 and the slot 613, after the pin 63 is inserted into the slot 613, the first and second covers 30 and 40 cannot rotate, so that the first cover 30 can be ensured to be perpendicular to the first side plate 10, and the whole drag chain is prevented from being scattered due to unfolding. Meanwhile, after the plug 63 is inserted into the slot 613, the cover plate 632 covers the rotating shaft 612 and also covers the opening of the semicircular groove 621.

In use, the inner side of the drag chain for easy wire installation can be opened when needed, that is, the first cover plate 30 is opened, as shown in fig. 5, at this time, the pin 63 in the second cover plate 40 is inserted into the slot 613, and the pin in the first cover plate 30 is pulled out from the slot 613. When the outer side is required to be opened, the second cover plate 40 on the outer side is opened, as shown in fig. 6, the latch 63 in the second cover plate 40 is pulled out from the slot 613, and the latch 63 in the first cover plate 30 is inserted into the slot 613. When the wire harness or the pipe is installed in the drag chain, the pins 63 of the first and second cover plates 30 and 40 are inserted into the slots 613, so as to fix the first and second cover plates 30 and 40, as shown in fig. 7.

Compared with the prior art, the drag chain convenient for wire installation provided by the utility model has the advantages that through the structural design of the first and second connecting mechanisms 50 and 60 for connecting the first and second side plates 10 and 20 and the first and second cover plates 30 and 40, the first cover plate 30 or the second cover plate 40 can be opened to place a wire harness or a pipeline in the drag chain, so that the wire harness or the pipeline is prevented from penetrating into the drag chain in a penetrating manner. Specifically, before the wire harness and the pipe are not threaded, the plug pin 63 is not inserted into the slot 613, so that the clamping hook 513 and the clamping hole 522 can be disengaged from each other by a tool such as a straight screwdriver, each of the first cover plate 30 and the second cover plate 40 can rotate around the rotating shaft 612 to open the drag chain, and the wire harness or the pipe can be placed into the drag chain, thereby reducing labor intensity and improving working efficiency. After the wiring harness or the pipeline is placed in the drag chain, the clamping hook 513 is firstly hooked into the clamping hole 522, and due to the matching of the insertion block 512 and the insertion groove 521, the bonding strength between the first cover plate 30 and the second cover plate 40 and the first side plate 10 and the second side plate 20 can be improved, the bonding strength of the clamping hole 522 can be ensured, and the clamping hook 513 is prevented from being separated from the clamping hole 522. The bolt 63 is inserted into the slot 613 through the through hole 622, so that the engagement hook 513 is prevented from being disengaged from the engagement hole 522, and the rotation shaft 612 is prevented from being disengaged from the semi-circular groove 621, thereby achieving the purpose of stability and reliability.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
