Description

Technical Field

[0001] This utility model relates to the field of gripper technology, and in particular to a self-locking quick-release gripper. Background Technology

[0002] Bolts, with their simple structure and low cost, have become widely used connecting components in power transmission lines. Because transmission lines are located outdoors, complex weather conditions can cause vibrations, expansion, or contraction, leading to loose bolts and creating safety hazards. Bolts are crucial for the safe and reliable operation of power transmission lines.

[0003] Currently, bolt tightening of transmission lines is still mainly done manually under live-line conditions. In high-altitude, high-voltage, and harsh environments, manual operation is inefficient. Furthermore, due to the widespread use of ultra-high voltage power grids and multi-circuit towers, voltage levels are getting higher and higher, and the distance between phases is getting closer and closer, making manual live-line operation extremely dangerous. Utility Model Content

[0004] The purpose of this invention is to provide a self-locking quick-release clamp, which aims to solve the problem of low efficiency in existing power transmission line bolt fastening methods.

[0005] To achieve the above objectives, this utility model provides a self-locking quick-release gripper, including a base, a release element, a latch, two torsion springs, and two grippers. The release element is installed on one side of the base, the latch is slidably connected to the base and located on the side of the base near the release element, the two grippers are rotatably connected to the base and located on the base, and the two torsion springs are installed on the side of the base near the grippers.

[0006] The base has two mounting screw holes, both of which are located at the bottom of the base.

[0007] The release element includes a button and a protrusion. The button is slidably connected to the base and located on one side of the base. The protrusion is fixedly connected to the button and located on the button.

[0008] The release component further includes a spring, which is fixedly connected to the button and the base, and is located between the base and the button.

[0009] The latch has a groove and a second spring. The groove is located on the latch, and the second spring is fixedly connected to the latch and the base, and is located between the base and the latch.

[0010] This utility model discloses a self-locking quick-release clamp. The base provides installation conditions for the release element, the latch, the two torsion springs, and the two clamps. When a tubular object needs to be clamped, the base is moved closer to the tubular object, and the two clamps rotate towards the tubular object until they reach a preset angle. At this point, the latch holds the two clamps, thus fixing the tubular object in place. When it needs to be removed, the release element is pressed, which moves the latch away from the clamps, releasing the clamps from their position. The rebound force of the two torsion springs resets the clamps, releasing them from their position on the tubular object. This solves the problem of low efficiency in existing power transmission line bolt fastening methods. Attached Figure Description

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] Please see Figures 1-3 This utility model provides a self-locking quick-release gripper, including a base 1, a release member, a latch 2, two torsion springs 3 and two grippers 4. The release member is installed on one side of the base 1. The latch 2 is slidably connected to the base 1 and is located on the side of the base 1 near the release member. The two grippers 4 are rotatably connected to the base 1 and are located on the base 1 respectively. The two torsion springs 3 are respectively installed on the side of the base 1 near the grippers 4.

[0018] In this embodiment, the base 1 provides installation conditions for the release member, the latch 2, the two torsion springs 3, and the two grippers 4. When it is necessary to clamp the tubular object, the base 1 is moved towards the side closer to the tubular object. The two grippers 4 are rotated towards the side closer to the tubular object until the two grippers 4 rotate to a preset angle. At this time, the latch 2 holds the two grippers 4, and the tubular object can be fixed by the two grippers 4. When it is necessary to remove it, the release member is pressed. The release member drives the latch 2 to move away from the grippers 4, releasing the restriction on the two grippers 4. The rebound force of the two torsion springs 3 resets the two grippers 4, and the two grippers 4 release the restriction on the tubular object, thereby solving the problem of low efficiency of the existing power transmission line bolt fastening method.

[0019] Furthermore, the base 1 has two mounting screw holes 5, both of which are located at the bottom of the base 1.

[0020] In this embodiment, the fixture can be installed on a preset device through the two mounting screw holes 5, and the two mounting screw holes 5 are universal screw holes.

[0021] Furthermore, the release element includes a button 6 and a protrusion 7. The button 6 is slidably connected to the base 1 and located on one side of the base 1. The protrusion 7 is fixedly connected to the button 6 and located on the button 6.

[0022] In this embodiment, pressing the button 6 can move the protrusion 7, and the movement of the protrusion 7 can move the latch 2.

[0023] Furthermore, the release element also includes a spring 8, which is fixedly connected to the button 6 and the base 1, and is located between the base 1 and the button 6.

[0024] In this embodiment, the button 6 can be reset by the rebound force of the spring 8.

[0025] Furthermore, the latch 2 has a slanted groove 9 and a second spring 10. The slanted groove 9 is located on the latch 2, and the second spring 10 is fixedly connected to the latch 2 and to the base 1, and is located between the base 1 and the latch 2.

[0026] In this embodiment, the inclined groove 9, in conjunction with the protrusion 7, can drive the latch 2 to move, and the latch 2 can be reset by the rebound force of the spring 10.

[0027] When a tubular object needs to be clamped, the base 1 is moved closer to the tubular object. The two grippers 4 are then rotated closer to the tubular object until they reach a preset angle. At this point, the latch 2 holds the two grippers 4 in place, thus securing the tubular object. When it needs to be removed, the button 6 is pressed. The button 6 moves the protrusion 7 within the inclined groove 9. The protrusion 7 moves the latch 2 away from the grippers 4, releasing the restriction on the two grippers 4. The rebound force of the two torsion springs 3 resets the two grippers 4, thus releasing the restriction on the tubular object. This solves the problem of low efficiency in existing power transmission line bolt fastening methods.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
