Detailed implementation mode

[0016] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0017] As Figures 1-4 shown, the present invention provides a drag chain that can be installed with wires on the side, including a plurality of chain links connected end to end. The chain links include a first side plate 1 and a second side plate 2 that are symmetrically distributed and parallel to each other. The top of the first side plate 1 is hinged with a cover plate 3. One end of the cover plate 3 is connected to the second side plate 2 through a first buckle 4. The first buckle 4 includes a first U-shaped elastic buckle 41. One end of the first U-shaped elastic buckle 41 is fixedly connected to the bottom of the cover plate 3. A limit projection 42 is provided on the outer surface of the other end of the first U-shaped elastic buckle 41. An upwardly open first groove 43 is provided at the top of the second side plate 2. A limit card slot 44 adapted to the limit projection 42 is provided on one side of the first groove 43. The bottom of the first side plate 1 is provided with a bottom plate 5 perpendicular to the first side plate 1. One end of the bottom plate 5 is connected to the second side plate 2 through a second buckle 6. A receiving space for accommodating pipelines is formed between the first side plate 1, the second side plate 2, the cover plate 3 and the bottom plate 5.

[0018] As Figures 1-3 shown, one end of the cover plate 3 is detachably installed on the upper part of the second side plate 2 through the first buckle 4. Specifically, the cover plate 3 drives the first U-shaped elastic buckle 41 to fall into the first groove 43. The limit projection 42 on the other end of the first U-shaped elastic buckle 41 will fall into the limit card slot 44, and the limit projection 42 is fixed in the limit card slot 44, so that the cover plate 3 is fixed to the upper part of the second side plate 2. The other end of the cover plate 3 can rotate around the hinge point above the first side plate 1. The bottom of the second side plate 2 and one side of the bottom plate 5 are detachably connected through the second buckle 6. When in use, the first U-shaped elastic buckle 41 at one end of the cover plate 3 can be disengaged from the first groove 43 to meet the front installation of the pipeline. At the same time, the upper and lower parts of the second side plate 2 can be respectively removed from the cover plate 3 and the bottom plate 5 to realize the side installation of the pipeline.

[0019] A disassembly hole 45 communicating with the limit card slot 44 is provided on the second side plate 2.

[0020] As Figure 1 and Figure 3 shown, by inserting a tool such as a screwdriver into the disassembly hole 45, the limit protrusion 42 is disengaged from the limit card slot 44, facilitating the removal of the first U-shaped elastic buckle 41 from the first groove 43, which provides convenience for disassembling the cover plate 3.

[0021] A limit groove 7 is provided at the bottom of one end of the bottom plate 5 close to the second side plate 2. A limit plate 8 integrally formed with the second side plate 2 and adapted to the limit groove 7 is provided at the lower part of the second side plate 2. The second buckle 6 includes a second groove 61 with a downward opening and provided on the limit groove 7. Second U-shaped elastic buckles 62 are installed on both sides in the second groove 61. One end of the second U-shaped elastic buckle 62 is fixedly connected to the second groove 61. A clamping protrusion 63 with a triangular cross-section is provided at one end of each of the second U-shaped elastic buckles 62. The clamping protrusions 63 on the two second U-shaped elastic buckles 62 are arranged oppositely. A clamping block 64 with a quadrilateral cross-section is connected to the limit plate 8 through a clamping plate. The clamping block 64 penetrates into the gap between the two clamping protrusions 63, and the clamping block 64 is fixed by the two clamping protrusions 63.

[0022] As Figure 4 shown, the second side plate 2 and the bottom plate 5 are fixed together by the second U-shaped elastic buckle 62, the clamping protrusion 63 and the clamping block 64. Specifically, the clamping block 64 passes through the gap between the two clamping protrusions 63. During the installation or disassembly process, the clamping protrusion 63 is squeezed by the clamping block 64, and the two clamping protrusions 63 move away from each other, increasing the gap between the two clamping protrusions 63, so as to meet the requirement for the clamping block 64 to enter or exit. After the clamping block 64 enters or exits from the gap between the two clamping protrusions 63, under the elastic action of the second U-shaped elastic buckle 62, the gap between the two clamping protrusions 63 returns to its original state. Without being driven by an external force, the clamping block 64 is always located in the gap between the two second U-shaped elastic buckles 62; under the action of the first buckle 4 and the second buckle 6, the second side plate 2 can be disengaged from the cover plate 3 and the bottom plate 5, which facilitates the installation of pipelines from the side in the case of a narrow installation space and provides convenience for the installation of pipelines.

[0023] First rotation grooves 9 are provided on the outer side surfaces of one ends of the first side plate 1 and the second side plate 2. Connecting rotating shafts 10 are provided in the first rotation grooves 9. Second rotation grooves 11 are provided on the outer side walls of the other ends of the first side plate 1 and the second side plate 2. Connecting holes 12 adapted to the connecting rotating shafts 10 are provided on the second rotation grooves 11. The connecting rotating shafts 10 on the same link are located at the same end of the link. The connecting holes 12 on the same link are located at the same end of the link. The connecting rotating shaft 10 on the upper side surface of any link cooperates with the connecting hole 12 on the adjacent link.

[0024] As Figure 1 shown, when the link sections are connected, the second rotating slots 11 on the adjacent rear link sections cooperate with the first rotating slots 9, and the connecting rotating shaft 10 is rotatably installed in the connecting holes 12 on the rear link sections, so that the link sections can rotate around the connecting rotating shaft 10.

[0025] The first sector-shaped sliding grooves 13 and the first sector-shaped sliding blocks 14 are respectively arranged on the first rotating slots 9, and the second sector-shaped sliding grooves 15 and the second sector-shaped sliding blocks 16 are respectively arranged on the second rotating slots 11. The first sector-shaped sliding block 14 at the front end rotates along the connecting rotating shaft 10 in the second sector-shaped sliding groove 15 on the adjacent rear link section, and the second sector-shaped sliding block 16 at the rear end rotates along the connecting rotating shaft 10 in the first sector-shaped sliding groove 13 on the adjacent front link section.

[0026] As Figure 1 shown, in this embodiment, for the convenience of description, the two link sections are divided into a front link section and a rear link section in the direction of the length of the drag chain. During installation, the second sector-shaped sliding block 16 on the rear link section is installed in the first sector-shaped sliding groove 13 on the front link section, and at the same time, the first sector-shaped sliding block 14 on the front link section is installed in the second sector-shaped sliding groove 15 on the rear link section, so that the second sector-shaped sliding block 16 rotates around the connecting rotating shaft 10 in the first sector-shaped sliding groove 13, and the first sector-shaped sliding block 14 rotates around the connecting rotating shaft 10 in the second sector-shaped sliding groove 15, restricting the rotation angle between the link sections.

[0027] Principle of use: When installing the pipeline from the front and it is necessary to open the cover plate 3, insert a tool similar to a screwdriver into the disassembly hole 45, so that the limit protrusion 42 is disengaged from the limit card slot 44, and the cover plate 3 can be opened; if it is necessary to open the second side plate 2 from the side due to narrow installation space, the second side plate 2 is detached from the cover plate 3 and the bottom plate 5 respectively. During specific disassembly, insert a screwdriver into the disassembly hole 45, the end of the screwdriver pushes the limit protrusion 42 to disengage from the limit card slot 44, and then apply a downward force to the second side plate 2, so that the clamping block 64 at the bottom of the second side plate 2 disengages from the gap between the two second U-shaped elastic buckles 62, and the second side plate 2 can be detached, facilitating the installation of the pipeline from the side. After the pipeline is installed, hold the second side plate 2 and install it from bottom to top. The clamping block 64 squeezes the clamping protrusion 63 upward and moves backward, so that the clamping block 64 passes through the gap between the two clamping protrusions 63. After the clamping block 64 passes through, the two clamping protrusions 63 return to their original state to limit the clamping block 64 in the gap between the two second U-shaped elastic buckles 62. At the same time, the first groove 43 moves upward, so that the first U-shaped elastic buckle 41 falls into the first groove 43. As the first groove 43 continues to move upward, the limit protrusion 42 falls into the limit card slot 44 for fixation, realizing the installation of the second side plate 2.

Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar means to replace them, but they will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
