Abstract
Description
Technical Field
[0001] This application belongs to the field of cable construction technology, specifically relating to a self-locking device clamp. Background Technology
[0002] In the existing technology, during the setting up of power systems, it is often necessary to use wire clamps to fix cables. A wire clamp is a metal fitting used to connect cables and electrical equipment. It is mainly used to transmit electrical loads and bear certain mechanical loads. It is usually used for the connection of outgoing terminals of electrical equipment such as transformers, circuit breakers, instrument transformers, disconnect switches, and wall bushings.
[0003] In existing technologies, traditional equipment clamps have the drawback of not being able to achieve a self-locking function. In actual implementation, traditional equipment clamps present many inconveniences and safety hazards in many application scenarios. For example, in fields such as conveyor lines, pipeline installation, and power line maintenance, clamps need to maintain a connection state for a long time. The lack of a self-locking function will lead to accidental loosening of the clamps, causing serious dangers such as equipment shutdown, material leakage, and electric shock to personnel. Furthermore, because the clamps cannot self-lock, personnel need to frequently calibrate and adjust them during operation, which reduces work efficiency and increases labor intensity. Therefore, there is an urgent need to make improvements. Utility Model Content

[0024] Combination Figure 1-8The content shown further illustrates the technical solution provided in this application: a self-locking device clamp, including a lower clamping seat 1, an upper clamping seat 2 covering the lower clamping seat 1, and a self-locking mechanism 3 disposed between the lower clamping seat 1 and the upper clamping seat 2. When the upper clamping seat 2 covers the lower clamping seat 1, the self-locking mechanism 3 is used to restrict the upper clamping seat 2 from moving away from the lower clamping seat 1. The self-locking mechanism 3 includes a first locking piece 30 disposed on the upper clamping seat 2, a second locking piece 31 rotatably disposed on the lower clamping seat 1, and an elastic member 32 disposed between the second locking piece 31 and the lower clamping seat 1. The elastic member 32 is used to drive the second locking piece 31 to rotate towards the first locking piece 30, so that the second locking piece 31 engages with the first locking piece 30.
[0025] This application provides a self-locking device wire clamp, which includes a lower clamping seat, an upper clamping seat covering the lower clamping seat, and a self-locking mechanism disposed between the lower clamping seat and the upper clamping seat. The self-locking mechanism includes a first locking piece disposed on the upper clamping seat, a second locking piece rotatably disposed on the lower clamping seat, and an elastic member disposed between the second locking piece and the lower clamping seat. By providing the elastic member, the elastic member can drive the second locking piece to rotate towards the first locking piece, so that the second locking piece engages with the first locking piece, thereby restricting the upper clamping seat from moving away from the lower clamping seat, and finally realizing the self-locking function of the wire clamp. It can ensure that the wire clamp is in a connected state for a long time without the need for frequent calibration and adjustment by operators. It has the advantages of simple structure, convenient operation, saving labor costs, and easy promotion and implementation.
[0026] In this embodiment, the self-locking mechanism 3 further includes an engaging portion 38 on the first locking piece 30 and a toothed portion 33 on the second locking piece 31. When the elastic member 32 drives the second locking piece 31 to rotate closer to the first locking piece 30, the toothed portion 33 engages with the engaging portion 38 to restrict the upper clamping seat 2 from moving away from the lower clamping seat 1.
[0027] In this embodiment, the elastic element 32 includes a first elastic end and a second elastic end. The lower clamping seat 1 is provided with a first mounting hole 39, and the second locking piece 31 is provided with a second mounting hole 34. The first elastic end can be matched and extended into the first mounting hole 39, and the second elastic end can be matched and extended into the second mounting hole 34, so as to drive the second locking piece 31 to rotate towards the first locking piece 30.
[0028] In actual implementation, the elastic element is a torsion spring. The first elastic end of the torsion spring can be matched and extended into the first mounting hole, and the second elastic end of the torsion spring can be matched and extended into the second mounting hole. When the second locking piece rotates away from the lower clamping seat, the spring will undergo elastic deformation to drive the second locking piece to rotate towards the first locking piece, so that the second locking piece is engaged with the first locking piece, thereby realizing the self-locking function between the lower clamping seat and the upper clamping seat.
[0029] In this embodiment, a clamping station 4 for clamping cables is also included. The clamping station 4 includes a lower clamping groove 40 on the lower clamping seat 1 and an upper clamping groove 41 on the upper clamping seat 2. When the upper clamping seat 2 covers the lower clamping seat 1, the upper clamping groove 41 and the lower clamping groove 40 together form the clamping station 4.
[0030] In this embodiment, clamping teeth 42 are provided on the inner surface of the upper clamping groove 41 and / or the lower clamping groove 40.
[0031] In actual implementation, by setting clamping teeth, when the cable is clamped between the lower clamping seat and the upper clamping seat, the friction between the upper clamping seat, the lower clamping seat, and the cable can be increased, thereby effectively improving the clamping stability of the cable.
[0032] In the implementation of this embodiment, a flipping mechanism 5 is also provided between the upper clamping seat 2 and the lower clamping seat 1. The upper clamping seat 2 can be flipped towards the lower clamping seat 1 through the flipping mechanism 5 so that the upper clamping seat 2 covers the lower clamping seat 1.
[0033] In this embodiment, the flipping mechanism 5 includes a flipping shaft 50 disposed on the lower clamping seat 1 and a flipping groove 51 disposed on the upper clamping seat 2 at the position corresponding to the flipping shaft 50. The flipping shaft 50 can be matched and extended into the flipping groove 51 so that the upper clamping seat 2 rotates around the flipping shaft 50 toward or away from the lower clamping seat 1.
[0034] In the implementation of this embodiment, a fastening component 6 is also included, which is used to restrict the upper clamping seat 2 from moving away from the lower clamping seat 1.
[0035] In this embodiment, the fastening component 6 includes fastening holes 60 provided on both the upper clamping seat 2 and the lower clamping seat 1, and fasteners 61 that are matched and inserted into the fastening holes 60.
[0036] In actual implementation, the fastening hole is a threaded hole and the fastener is a fastening bolt. After the self-locking mechanism locks the upper clamping seat and the lower clamping seat, the fastening component can further limit the upper clamping seat to rotate away from the lower clamping seat, so as to further improve the locking stability of the upper clamping seat and the lower clamping seat.
[0037] This application provides a self-locking device wire clamp, which includes a lower clamping seat, an upper clamping seat covering the lower clamping seat, and a self-locking mechanism disposed between the lower clamping seat and the upper clamping seat. The self-locking mechanism includes a first locking piece disposed on the upper clamping seat, a second locking piece rotatably disposed on the lower clamping seat, and an elastic member disposed between the second locking piece and the lower clamping seat. By providing the elastic member, the elastic member can drive the second locking piece to rotate towards the first locking piece, so that the second locking piece engages with the first locking piece, thereby restricting the upper clamping seat from moving away from the lower clamping seat, and finally realizing the self-locking function of the wire clamp. It can ensure that the wire clamp is in a connected state for a long time without the need for frequent calibration and adjustment by operators. It has the advantages of simple structure, convenient operation, saving labor costs, and easy promotion and implementation.
