Description

Technical Field

[0001] The utility model relates to the field of torque locking connection devices, in particular to an anti-loosening torque locking connection device. Background Art

[0002] The torque locking connection device is a connection device widely used in the fields of electricity, communications, machinery, etc. Its main function is to ensure the tightness and stability between the connected parts through torque locking. The torque locking connection device is also a device that uses the torque principle for tightening and connecting. By rotating fasteners such as bolts or nuts, a certain torque is applied to generate sufficient clamping force between the connecting parts, thereby achieving tightening and connection. The torque locking connection device can adapt to connecting parts of different sizes and shapes to meet diverse connection needs.

[0003] After searching, a torque locking connection device with publication number CN208014911U is found, which specifically discloses a torque locking connection device, including a main body and at least one clamping bolt, including a first connecting part and a second connecting part, the second connecting part is located on one side of the first connecting part, the first connecting part includes a round through hole and a waist hole, the waist hole is located on one side of the round through hole, the second connecting part includes at least one clamping screw hole and a wire insertion hole, the wire insertion hole and the clamping screw hole are perpendicularly intersected, the clamping bolt is detachably arranged in the clamping screw hole, the bolt head of the clamping bolt includes a first bolt head and a second bolt head, the first bolt head is located at the lower end of the second bolt head, the maximum force torque at the connection between the first bolt head and the second bolt head is 20~25N·m, the torque locking connection device has a simple structure and is easy to use. The transformer output terminal and the distribution wire are connected through the main body, and the installation position can be adjusted by selecting the round through hole or the waist hole. The distribution wire is clamped by the clamping bolt, and the clamping bolt is provided with two bolt heads and a breaking torque to prevent damage to the wire due to excessive compression.

[0004] During use, the existing torque locking connection device only clamps the wire through the interference of the bolt and has no anti-loosening method. Therefore, when the two ends of the wire are dragged, the wire will be positionally offset in the torque locking connection device, causing the clamped wire to loosen. In the above-mentioned comparative case, the torque locking connection device also lacks an anti-loosening method. This not only affects the normal use of the wire under long-term use, but also may cause the wire and the torque locking connection device to become disconnected if the loosening is too large.

[0005] Therefore, it is necessary to invent an anti-loosening torque locking connection device to solve the above problems. Utility Model Content

[0006] The utility model aims to provide an anti-loosening torque locking connection device, which realizes, through the embedded groove, torsion spring, bottom anti-loosening splint, stud bolt, upper anti-loosening splint, hexagonal nut and half-moon clamping plate, that when the two ends of the wire are dragged, the wire fastened by the bottom anti-loosening splint and the upper anti-loosening splint can reduce the influence on the internal wire, strengthen the installation force of the torque locking connection device on the wire, and in this way, the two ends are tightened and pressed by the internal half-moon clamping plate, so that the wire is doubly locked inside the torque locking connection device, achieving the purpose of preventing loosening, ensuring the normal use of the wire, and reducing the wire and torque locking connection device. The effect of reducing the probability of disconnection, etc. is to solve the problem in the prior art that during use, the torque locking connection device only clamps the wire by the interference of the bolt, and there is no method to prevent loosening. In this way, when dragging occurs at both ends of the wire, the wire will be positionally offset in the torque locking connection device, thereby causing the clamped wire to loosen, etc., and the torque locking connection device in the above-mentioned comparative case also lacks a method to prevent loosening. This not only affects the normal use of the wire under long-term use, but also causes the wire and the torque locking connection device to become disconnected if the loosening is too large.

[0007] In order to achieve the above-mentioned object, the present utility model provides the following technical solutions: an anti-loosening torque locking connection device, comprising a locking connection body, a body for assisting the connection of wires;

[0014] Preferably, the number of the transverse anti-slip grooves is set to be multiple, and the multiple transverse anti-slip grooves are distributed at equal intervals on the semi-lunar clamping plate.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. The utility model is provided with an embedded groove, a torsion spring, a bottom anti-loosening splint, a stud bolt, an upper anti-loosening splint, a hexagonal nut and a half-moon clamping plate. When using the torque locking connection device, first twist the hexagonal nut on the stud bolt to expand the distance between the bottom anti-loosening splint and the upper anti-loosening splint, allowing the wire to pass through the locking connection body, and then twist the hexagonal nut.

In addition, the tightening of the two ends and the compression of the internal half-moon clamping plate allow the wire to be doubly locked inside the torque locking connection device, achieving the purpose of preventing loosening, ensuring the normal use of the wire, and reducing the probability of disconnection between the wire and the torque locking connection device.

[0017] 2. The utility model is provided with a torque locking bolt, a half-moon clamping plate, a tightening nut, an anti-slip gasket, an internal threaded sleeve and a transverse anti-slip groove. When the torque locking connection device is used, multiple groups of transverse anti-slip grooves are provided inside the half-moon clamping plate, which enhances the friction force when the half-moon clamping plate contacts the outside of the wire, and also improves the clamping force of the half-moon clamping plate itself. At the same time, when the torque locking bolt is torqued, the tightening force of the torque locking bolt is increased by tightening the nut and the anti-slip gasket, reducing the local loosening caused by slipping of the torque locking bolt inside the locking connection body. To a certain extent, the tightened torque locking bolt can also reduce the probability of the wire loosening inside the locking connection body. BRIEF DESCRIPTION OF THE DRAWINGS
