Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drag chain testing machines, in particular to a wire drag chain testing machine with an anti-slip structure. Background Art
[0002] With the development of science and technology and the continuous advancement of industrial technology, the use of wires is increasing day by day. Wires are usually rope-like cables composed of several or several groups of conductors, with at least two conductors in each group twisted together. Wires are often bent by external forces when in use. For example, wires used in logistics conveying systems and cranes will be repeatedly bent and pulled by repetitive actions, which requires the use of a drag chain tester for testing.
[0003] Some equipment on the market generally has a through slot in the center of the drag chain, which can accommodate at least one wire to be tested. Since the through slot can accommodate multiple wires, multiple wires can be tested at one time, which has high work efficiency. The length of the drag chain is adjustable, and users can choose the length of the drag chain according to actual conditions.
[0004] However, in actual use, when the above-mentioned equipment is performing reciprocating testing, its wires will often be bent and then stretched, causing the wires to rub against the inside of the drag chain, which will easily damage the outer surface of the wires and cause inaccurate test data. In view of this, we propose a wire drag chain testing machine with an anti-slip structure. Utility Model Content
[0005] The utility model aims to provide a wire drag chain testing machine with an anti-drop structure to solve the problems raised in the above background technology.

[0010] Preferably, the size of the pressing piece is matched with the size of the mounting groove, and the pressing piece is arranged inside the mounting groove, which can make the pressing piece move well inside the mounting groove.
[0011] Preferably, the distance between the bottom of the fixing block and the bottom of the inner wall of the drag chain is adapted to the size of the wire, and the fixing blocks are evenly distributed on the inner wall of the drag chain in a curved drive array, which can better limit the wire inside the drag chain.
[0012] Preferably, the other end of the drag chain is fixedly connected to the top of the fixing member, and one end of the clamping block passes through one side of the drag chain to the inside of the clamping slot, which enables the clamping block to well limit the limiting member.
[0013] Preferably, a limiting groove is provided at the bottom of the limiting member, and an anti-slip member is fixedly connected to the inner wall of the limiting groove.
[0014] Preferably, the anti-slip member is composed of a protrusion and a breathing elastic member, and the anti-slip member is evenly distributed on the inner wall of the limiting groove in a circular array.
[0015] Compared with the prior art, the utility model provides a wire drag chain testing machine with an anti-slip structure, which has the following beneficial effects:
[0016] 1. The wire drag chain testing machine with an anti-slip structure places the wires inside the drag chain to prevent the wires from being damaged by excessive friction during use of the equipment. The pressing block is subject to the elastic force of the spring to limit the wires in the groove provided at the bottom of the pressing block, and the inner wall of the groove at the bottom of the pressing block is provided with convex strips, so that the wires can be better limited. At the same time, the outer surface of the groove at the bottom of the pressing block is provided with rounded corners, so that the wires will not be worn when passing through the bottom of the pressing block, so that the wires can fit well with the inner wall of the drag chain when the equipment is in use, so that the wires will not be damaged by excessive friction.
[0017] 2. The wire drag chain testing machine with an anti-slip structure, in order to better limit the position of the wire inside the drag chain, the limiting piece is clamped on the outer surface of the wire near the end, and then the clamping block is clamped into the inside of the clamping slot, so that the wire is limited and the wire can be clamped in the inside of the limiting slot at the same time, so that the anti-slip piece can contact the outer surface of the wire. The anti-slip piece is composed of a protrusion and an arc-shaped elastic piece, which makes the bottom of the arc-shaped elastic piece contact with the outer surface of the wire. The arc-shaped elastic piece can better fit the outer surface of the wire, thereby increasing the friction between the anti-slip piece and the outer surface of the wire so that the wire can be better limited.
