Description

Technical Field

[0001] The utility model relates to the technical field of drag chains, in particular to a drag chain with a positioning and plugging function. Background Technique

[0002] A drag chain, also known as a cable protection drag chain, is a device that binds cables or wires or pneumatic tubes and hydraulic tubes to facilitate their rotation and movement. It is composed of flexible unit links spliced together, and its appearance is similar to a tank chain, consisting of many unit links, and the links rotate freely between them.

[0003] Since the structures on both sides of the current drag chain are very similar, during the assembly process, workers need to carefully observe the form of the drag chain. During this process, it is very easy for workers to install it in the wrong position and prone to misinstallation problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a drag chain with a positioning and plugging function, which overcomes the deficiencies of the prior art and effectively solves the problem of easy misinstallation of the drag chain.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A drag chain with a positioning and plugging function includes a drag chain assembly. Symmetrically distributed side plate members are arranged inside the drag chain assembly, and bosses are arranged on the outer walls of one sides of the two side plate members. A first convex block and a second convex block are respectively fixedly connected to the outer walls of the two bosses. An insertion port one and an insertion port two are respectively opened on the outer walls of one sides of the two side plate members, and positioning grooves are respectively opened on the outer walls of the other sides of the two side plate members.

[0007] Preferably, the outer diameter dimension of the first convex block is smaller than the dimension of the second convex block, and the inner diameter dimension of the insertion port one is smaller than the outer diameter dimension of the insertion port two.

[0008] Preferably, cutouts are opened on the outer walls of the first convex block and the second convex block, and the included angle of the cutouts is greater than the inner angles of the insertion port one and the insertion port two.

[0009] Preferably, the size of the boss is adapted to the size of the positioning groove, and the sizes of the bosses on the two side plate members are inconsistent.

[0010] Preferably, the side plate member includes an outer plate and an inner insertion plate, and the positioning groove is opened on the outer wall of the outer plate, and the boss is arranged on the outer wall of the inner insertion plate.

[0011] Preferably, a top plate connecting member is fixedly connected between the tops of the two side plate members.

[0012] Preferably, a bottom plate connecting member is fixedly connected between the bottoms of the two side plate members, and an arc-shaped groove is formed in the outer wall of the bottom of the bottom plate connecting member.

[0013] Preferably, a wire threading opening for restraining cables is provided inside the drag chain assembly among the side plate member, the top plate connecting member and the bottom plate connecting member.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. For the drag chain with a positioning and plugging function in this design, the bosses on each side plate member can be matched with the corresponding positioning grooves. Since the sizes of the two bosses are inconsistent, during the assembly process, if the installation is reversed, the bosses cannot be inserted into the positioning grooves, eliminating the possibility of reverse installation and saving the time for manual observation.

[0016] 2. For the drag chain with a positioning and plugging function in this design, two bosses with inconsistent sizes are additionally added to the two bosses with different sizes. The first boss and the first plugging opening, and the second boss and the second plugging opening correspond to each other in pairs, playing a role of rapid positioning and further reducing the difficulty during assembly.

[0017] 3. For the drag chain with a positioning and plugging function in this design, since the sizes of the bosses and the bosses on the side plate members on both sides are inconsistent, it is more conducive for workers to observe and install. When the assembly is correct, there will be no gap, preventing the drag chain from being installed reversely, which is very easy to identify and is easy to assemble.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Embodiment 1. Refer to Figures 1-4 , a drag chain with a positioning and plugging function, including a drag chain assembly 1. Symmetrically distributed side plate members 2 are arranged inside the drag chain assembly 1, and bosses 3 are arranged on the outer walls of one sides of the two side plate members 2.

[0025] In this embodiment, the boss 3 on each side plate member 2 can be matched with the corresponding positioning groove 8. Since the sizes of the two bosses 3 are inconsistent, during the assembly process, if the installation is reversed, the boss 3 cannot be inserted into the positioning groove 8, eliminating the possibility of reverse installation and saving the time for manual observation.

[0026] Embodiment 2. Refer to Figures 1-2 , a drag chain with a positioning and plugging function. A first convex block 4 and a second convex block 6 are respectively fixedly connected to the outer walls of one sides of the two bosses 3, and a first insertion port 5 and a second insertion port 7 are respectively formed in the outer walls of one sides of the two side plate members 2.

[0027] In this embodiment, two convex blocks with inconsistent sizes are additionally added to the two bosses 3 with different sizes. The first convex block 4 and the first insertion port 5, and the second convex block 6 and the second insertion port 7 correspond to each other in pairs, playing a role of rapid positioning and further reducing the difficulty during assembly.

[0028] Embodiment 3. Refer to Figure 3 , a drag chain with a positioning and plugging function. Positioning grooves 8 are formed in the outer walls of the other sides of the two side plate members 2.

[0029] In this embodiment, since the bosses 3 and the convex blocks on the two side plate members on both sides have inconsistent sizes, it is more conducive for workers to observe and install. When the assembly is correct, there will be no gap, preventing the drag chain from being installed in reverse, being very easy to identify, and facilitating assembly.

[0030] Refer to Figures 1-2 , the outer diameter of the first convex block 4 is smaller than the size of the second convex block 6, and the inner diameter of the first insertion port 5 is smaller than the outer diameter of the second insertion port 7.

[0031] Refer to Figures 1-2 , notches 9 are formed in the outer walls of the first convex block 4 and the second convex block 6, and the included angle of the notch 9 is larger than the inner angles of the first insertion port 5 and the second insertion port 7.

[0032] Refer to Figure 1 And Figure 3 , the size of the boss 3 is adapted to the size of the positioning groove 8, and the sizes of the bosses 3 on the two side plate members 2 are inconsistent.

[0033] Reference Figures 1-3 , the side plate member 2 includes an outer plate 10 and an inner inserted plate 11, and the positioning groove 8 is formed on the outer wall of the outer plate 10, and the boss 3 is provided on the outer wall of the inner inserted plate 11.

[0034] Reference Figures 1-3 , a top plate connecting member 12 is fixedly connected between the tops of the two side plate members 2, a bottom plate connecting member 13 is fixedly connected between the bottoms of the two side plate members 2, and an arc-shaped groove 14 is formed on the outer wall of the bottom of the bottom plate connecting member 13. A wire threading port 15 for binding cables is provided inside the drag chain assembly 1 among the side plate member 2, the top plate connecting member 12 and the bottom plate connecting member 13.

[0035] Working principle: The drag chain assembly 1 is mainly composed of a top plate connecting member 12, a bottom plate connecting member 13 and two side plate members 2. The sizes of the bosses 3 on each side plate member 2 are different, but they can all be matched with the corresponding positioning grooves 8. Therefore, during the assembly process, at the same time, each boss 3 has a bump with a different size. Since the bump one 4 and the insertion port one 5, and the bump two 6 and the insertion port two 7 correspond to each other in pairs, if the installation is reversed, the boss 3 and the bump cannot be inserted into the corresponding positioning groove 8 and insertion port, solving the problem of reverse installation.
