Description

Technical Field

[0001] This utility model relates to the field of electrical fittings technology, and more specifically to a universal torque energy-saving parallel groove clamp. Background Technology

[0002] Parallel groove clamps are used for connecting small- to medium-section aluminum stranded wires or steel-cored aluminum stranded wires, as well as steel stranded wires of overhead lightning protection wires, in positions where they are not subjected to tension. They are also used for jumper connections on non-straight-line towers. Electrical engineering materials (fittings) for connecting conductors are mainly used in power line engineering.

[0003] Reliable power supply is a crucial indicator of a power supply company's capability, reflecting the degree to which it meets users' electricity demands and serving as an important criterion for evaluating power quality. The reliability of line equipment is a significant factor affecting power supply reliability, and the performance of the numerous parallel cable clamps operating in urban and rural power grids directly impacts reliable power supply. Low reliability of these clamps necessitates increased inspection frequency and shorter maintenance cycles, leading to higher operating costs for power supply companies. Furthermore, faults or accidents involving these clamps can cause widespread power outages and threaten the safety of urban and rural residents.

[0004] Existing parallel groove clamps require hammering to firmly insert the wedge into the locking pin during use. This method makes it difficult to control the stress between the wedge and the locking pin, making it inconvenient to use. Utility Model Content

[0005] One advantage of this utility model is that it provides a universal torque energy-saving grooved clamp. It is a modification of the conventional wedge-type grooved clamp, which changes the installation method. It no longer requires hammering, but uses bolt tightening for installation. During the bolt tightening process, the wedge is pressed and pushed to move slowly inward, gradually increasing the stress and fixing it firmly. When replacing, it can be removed and reused simply by unscrewing the bolt.

[0006] To achieve at least one of the above advantages of this utility model, this utility model provides a universal torque energy-saving grooved clamp, including a locking pin and a wedge block disposed detachably inside the locking pin. The back of the locking pin is provided with a through threaded hole, and the wedge block is provided with an inclined groove at the position corresponding to the threaded hole. A movable block is disposed movably inside the inclined groove, and a bolt is disposed in the threaded hole by screwing in. The other end of the bolt passes through the threaded hole and extends into the inclined groove, abutting against the bottom surface of the movable block.

[0007] According to one embodiment of the present invention, one end of the locking pin is a wide opening for inserting a wedge, the other end of the locking pin is a narrow opening for locking the wedge, and the two inner sides of the locking pin are provided with a first arc-shaped groove.

[0008] According to one embodiment of the present invention, one end of the wedge is a narrow end, the other end of the wedge is a wide end, and a second arc-shaped groove is provided on both sides of the wedge.

[0009] According to one embodiment of the present invention, the top of the inclined groove is provided with a first inclined surface, the top of the moving block is provided with a second inclined surface with the same inclination angle as the first inclined surface, and the lower part of the moving block is a horizontal surface.

[0010] According to one embodiment of the present invention, an elliptical groove is provided on the horizontal surface to limit the range of movement of the bolt end. Attached Figure Description

[0020] This utility model provides a universal torque energy-saving parallel groove clamp, including a locking pin 1 and a wedge 2 detachably disposed inside the locking pin 1. The back of the locking pin 1 has a through-hole 13. The wedge 2 has a groove 23 corresponding to the groove 13. A movable block 24 is movably disposed inside the groove 23. A bolt is screwed into the groove 13, with the other end of the bolt penetrating the groove 13 and extending into the groove 23, abutting against the bottom surface of the movable block 24. One end of the locking pin 1 is... The wide opening 11 for inserting the wedge 2, the other end of the locking pin 1 is the narrow opening 12 for locking the wedge 2, and the two inner sides of the locking pin 1 are provided with a first arc-shaped groove; one end of the wedge 2 is a narrow end 22, the other end of the wedge 2 is a wide end 21, and the two sides of the wedge 2 are provided with a second arc-shaped groove; the top of the inclined groove 23 is provided with a first inclined surface, the top of the moving block 24 is provided with a second inclined surface with the same inclination angle as the first inclined surface, and the lower part of the moving block 24 is a horizontal surface; an elliptical groove 25 is provided on the horizontal surface to limit the range of movement of the bolt end.

[0021] The first embodiment of this utility model is as follows:

[0022] A universal torque energy-saving parallel groove clamp includes a locking pin 1 and a wedge 2 detachably disposed inside the locking pin 1. One end of the locking pin 1 is a wide opening 11 for inserting the wedge 2, and the other end of the locking pin 1 is a narrow opening 12 for locking the wedge 2. The two inner sides of the locking pin 1 are provided with a first arc-shaped groove. One end of the wedge 2 is a narrow end 22, and the other end of the wedge 2 is a wide end 21. The two sides of the wedge 2 are provided with a second arc-shaped groove. The first groove and the second groove form a circular groove for accommodating stranded wire. In use, the stranded wire is first placed into the first groove of the locking pin 1, and then the wedge 2 is firmly inserted into the first groove and the second groove to couple, thus completing the installation.

[0023] The locking pin 1 has an opening on its front side and a through-hole 13 on its back side. A groove 23 is provided on the wedge block 2 at a position corresponding to the groove 13. The groove 23 extends along the insertion direction of the wedge block 2. A first inclined surface is provided at the top of the groove 23. A movable block 24 is movably disposed inside the groove 23. A second inclined surface with the same inclination angle as the first inclined surface is provided at the top of the movable block 24. The lower part of the movable block 24 is horizontal. Due to the coupling of the first and second inclined surfaces, the movable block 24 can move within the first inclined surface. The inclined surface moves, and a bolt is screwed into the threaded hole 13. The other end of the bolt passes through the threaded hole 13 and extends into the inclined groove 23, abutting against the bottom surface of the moving block 24. When in use, when the bolt is screwed into the inclined groove 23, the bolt will abut against the bottom surface of the moving block 24 and push it. Since the moving block 24 cannot move laterally, the wedge 2 will move relative to it, thus slowly moving towards the square of the narrow opening 12 and gradually locking it. At the same time, it can also play a locking role. When replacing, it can be removed and reused simply by unscrewing the bolt.

[0024] To ensure that the moving block 24 does not come off, an elliptical groove 25 is provided on the horizontal surface to limit the range of movement of the bolt end. This not only allows the bolt to enter the groove smoothly, but also prevents the moving block 24 from accidentally coming off during the bolt screwing process.

[0025] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0026] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
