To meet the demands of urban power grid construction projects, the demand for related supporting equipment is also increasing, with tension clamps, which are frequently used in power grids, being one of the many power grid accessories.

[0003] In the existing technology, the tie rods used in the bundled tension clamps are all fixed by the threaded connection of nuts. However, during the maintenance of the bundled tension clamps, the nuts are small and easy to lose, which makes it impossible to lock the tie rods in place. Summary of the Invention

[0004] The purpose of this utility model is to provide a bundled tension clamp to solve the problem mentioned in the background art, where the tie rods used in the bundled tension clamp are all fixed by a nut thread connection. However, during the maintenance of the bundled tension clamp, the nuts are small and easily lost, making it impossible to lock the tie rods in place.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bundled tension clamp, comprising a pull plate, with connecting cylinders fixedly connected to both ends of the pull plate, an annular groove being formed on the inner wall of the connecting cylinder at one end, an adjusting nut being rotatably connected to the rear end of the connecting cylinder through the annular groove, and a connecting ring being fixedly connected to one end of the adjusting nut near the connecting cylinder, and the connecting ring being rotatably connected within the annular groove.

[0006] Preferably, the outer diameter of the connecting ring is larger than the inner diameter of the connecting cylinder.

[0007] Preferably, a pull rod is provided on the outer side of the pull plate, and the pull rod passes through the connecting cylinder and is threadedly connected to the adjusting nut.

[0008] Preferably, the upper and lower ends of the pull plate are provided with wire clamps. The wire clamps include a cover and a base. The cover has two first wire clamping grooves. The base has a second wire clamping groove located opposite to the first wire clamping grooves. A limiting groove is provided between the two first wire clamping grooves. A limiting block is fixedly connected between the two second wire clamping grooves. The limiting block is movably connected in the limiting groove. Several anti-slip blocks are fixedly connected to the surfaces of the first and second wire clamping grooves.

[0009] Preferably, the cover is made of aluminum.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "front," "rear," "inner," "outer," "vertical," and "horizontal," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figure 1-3This is a schematic diagram of a preferred embodiment of the present invention for a bundled tension clamp. In this embodiment, the bundled tension clamp includes a pull plate 1, with connecting cylinders 2 fixedly connected to both ends of the pull plate 1. An annular groove 21 is formed on the inner wall of the connecting cylinder 2 at one end. An adjusting nut 4 is rotatably connected to the rear end of the connecting cylinder 2 through the annular groove 21. A connecting ring 41 is fixedly connected to the end of the adjusting nut 4 near the connecting cylinder 2, and the connecting ring 41 is rotatably connected within the annular groove 21. The outer diameter of the connecting ring 41 is larger than the inner diameter of the connecting cylinder 2, which ensures that the adjusting nut 4 is difficult to detach from the annular groove 21 during rotation. At the same time, the adjusting nut 4 is installed in the connecting cylinder 2 by means of temperature difference. Combined with the structural design of the present invention, by embedding one end of the adjusting nut 4 inside the connecting cylinder 2, the adjusting nut 4 is ensured not to be lost after disassembly from the pull rod 5, effectively solving the problems mentioned in the background art.

[0023] In this embodiment, a pull rod 5 is provided on the outer side of the pull plate 1, and the pull rod 5 passes through the connecting cylinder 2 and is threadedly connected to the adjusting nut 4. This structural design allows the adjusting nut 4 to be threadedly connected to the pull rod 5 by rotating the adjusting nut 4, thereby driving the pull plate 1 to move horizontally and adjusting the base 32 and the cover 31 by pushing and driving them to engage.

[0024] In this embodiment, the upper and lower ends of the pull plate 1 are provided with wire clamps 3. The wire clamps 3 include a cover 31 and a base 32. Two first wire clamping grooves 311 are formed on the cover 31, and a second wire clamping groove 321 is formed on the base 32 at a position opposite to the first wire clamping grooves 311. By forming a limiting groove 312 between the two first wire clamping grooves 311 and fixing a limiting block 322 between the two second wire clamping grooves 321, and by movably connecting the limiting block 322 in the limiting groove 312, the problem that the two wire clamping grooves are still easy to shift relative to each other during the tightening process of the fixing nuts used to fix the cover 31 and the base 32 is solved. By fixing a number of anti-slip blocks 33 on the surfaces of the first wire clamping grooves 311 and the second wire clamping grooves 321, the cable is effectively prevented from falling off after being clamped.

[0025] In this embodiment, the cover 31 is made of aluminum. This design reduces resistance during current conduction and increases current conduction capability.

[0026] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
