Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of drag chains, and in particular relates to a plastic drag chain which is easy to assemble and disassemble. Background Art
[0002] Drag chains are products used to protect cables and hoses attached to mechanical equipment from entanglement, twisting and damage during operation. On most drag chains, two detachable connecting covers are often used to connect the left and right chain plates. The most common way to connect the detachable connecting covers and chain plates of plastic drag chains is by snap-on connection.
[0003] The connection structure of the chain plates on both sides of the existing drag chain is two detachable connection covers per section. Therefore, when disassembling and assembling, a single chain section needs to disassemble and assemble the connection cover twice. This may be inconvenient for some smaller drag chains to be disassembled and assembled in a narrow equipment installation space. The connection method between the detachable connection cover and the chain plate of the plastic drag chain is usually a snap connection. However, when disassembling, a tool such as a flat-blade screwdriver or a screwdriver is required to assist in disassembly at the snap connection, which is easy to cause damage or damage to the drag chain parts themselves. Utility Model Content
[0004] In order to solve the problems raised in the above background technology, the utility model provides a plastic drag chain which is easy to disassemble and assemble, and has the characteristics of being easy to use and reducing damage to parts.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plastic drag chain that is easy to disassemble and assemble, comprising a left chain plate and a right chain plate, an inner connecting plate is provided on one side of the left chain plate, a right chain plate is provided on one side of the inner connecting plate, a connecting cover plate is provided on the upper end between the left chain plate and the right chain plate, rear clamping shafts are symmetrically provided on both sides of the connecting cover plate, a wing plate is provided on one side of the rear clamping shaft, a front clamping shaft is provided on one side of the wing plate, a boss inclined surface is symmetrically provided on the upper end of the surface of the left chain plate, a front clamping hole is provided inside one end of the boss inclined surface, and a rear clamping hole is provided inside the other end of the boss inclined surface.
[0006] Preferably, the upper ends of the corresponding sides of the right chain plate and the left chain plate are also provided with a boss inclined surface, a front clamping hole and a rear clamping hole.
[0007] Preferably, a support block is provided at the bottom end of one side of the boss slope, and an abutment block is provided at the bottom end of the wing plate corresponding to the boss slope.
[0008] Preferably, one end of the rear clamping shaft and the front clamping shaft is provided with a tapered surface.
[0009] Preferably, the upper end surface of the boss slope is flush with the upper end surface of the left link plate.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] The utility model provides a detachable connection cover plate at one end, and its disassembly and assembly is relatively convenient, requiring less man-hours, and no screwdriver or screwdriver is required. Disassembly and assembly can be completed by knocking with a small wooden hammer, thereby reducing the probability of scratches and damage to parts, improving the convenience of using the drag chain, saving human resources, and reducing disassembly and assembly costs.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-4 The utility model provides the following technical solutions: a plastic drag chain that is easy to disassemble and assemble, comprising a left chain piece 1 and a right chain piece 3, an inner connecting plate 2 is arranged on one side of the left chain piece 1, a right chain piece 3 is arranged on one side of the inner connecting plate 2, a connecting cover plate 4 is arranged on the upper end between the left chain piece 1 and the right chain piece 3, rear clamping shafts 5 are symmetrically arranged on both sides of the connecting cover plate 4, a wing plate 6 is arranged on one side of the rear clamping shaft 5, a front clamping shaft 7 is arranged on one side of the wing plate 6, a boss inclined surface 8 is symmetrically arranged on the upper end of the surface of the left chain piece 1, a front clamping hole 9 is arranged inside one end of the boss inclined surface 8, and a rear clamping hole 10 is arranged inside the other end of the boss inclined surface 8.
[0019] Specifically, the upper ends of the right link plate 3 and the left link plate 1 corresponding to each other are also provided with a boss inclined surface 8 , a front locking hole 9 and a rear locking hole 10 .
[0020] By adopting the above technical solution, it is ensured that the connecting cover plate 4 is installed firmly and stably, thereby improving the stability of the single chain link assembly.
[0021] Specifically, a support block is disposed at the bottom end of one side of the boss slope 8 , and an abutment block is disposed at the bottom end of the wing plate 6 corresponding to the boss slope 8 .
[0022] By adopting the above technical solution, it is ensured that the wing plate 6 is supported after being installed in place, thereby playing a protective role.
[0023] Specifically, one end of the rear clamping shaft 5 and the front clamping shaft 7 is provided with a tapered surface.
[0024] By adopting the above technical solution, it is convenient to insert the rear clamping shaft 5 and the front clamping shaft 7 into the front clamping hole 9 and the rear clamping hole 10, thereby improving the installation efficiency.
[0025] Specifically, the upper end surface of the boss slope 8 is flush with the upper end surface of the left link plate 1 .
[0026] By adopting the above technical solution, it is ensured that the connecting cover plate 4 can be flush with the upper ends of the left chain plate 1 and the right chain plate 3 after installation without protruding, thereby improving the quality of equipment use.
[0027] Working principle and use process of the utility model: When the utility model is used, when assembling a single chain link of the plastic drag chain, firstly attach the wing plates 6 on both sides of the connecting cover plate 4 in the length direction to the boss inclined surfaces 8 on the inner sides of the left chain plate 1 and the right chain plate 3, and then pre-insert the front clamping shaft 7 into the front clamping hole 9 at an oblique angle, and gently tap the rear end edge of the connecting cover plate 4 along the length direction of the chain plate with a small wooden hammer or a rubber hammer, so that the front clamping shaft 7 on both sides of the connecting cover plate 4 is completely inserted into the front clamping hole 9, and at the same time, the wing plates 6 slide into the gap between the two groups of boss inclined surfaces 8, and the rear clamping shaft 5 is then clamped into the inside of the rear clamping hole 10, and the assembly of the single chain link is completed;
[0028] When disassembling, use a small wooden hammer to knock the front end edge of the connecting cover plate 4 at an oblique angle. As the wing plate 6 moves along the boss inclined surface 8 and gradually slides out of the gap, the rear clamping shaft 5 and the front clamping shaft 7 also slide out of the rear clamping hole 10 and the front clamping hole 9 to the pre-installed position, and finally the connecting cover plate 4 can be pulled out by hand, ensuring the convenience of disassembly and assembly of the connecting cover plate 4, saving human resources, reducing working hours, and no need to use a screwdriver or screwdriver, reducing the probability of scratches and damage to parts.
