It is mainly used for corner, connection and terminal connections in the power system to fix the conductor or lightning conductor on the insulator. The design of the strain clamp aims to withstand the full tension of the conductor or lightning conductor.
[0003] In the actual use process of the existing strain clamps, the clamps are prone to loosen due to the swinging of the conductor by the wind, resulting in the shaking of the bolts. Over time, in extreme weather, the strain clamps are likely to break away from the conductors, causing power failure problems. Therefore, it is necessary to provide a strain clamp to make the nut more stably fixed in the required position and the overall structure more firm and reliable. Summary of the Utility Model

[0007] A strain clamp body;
[0008] A reinforcement component, the reinforcement component includes a pressing plate, a limiting column, a limiting plate, a connecting column and a supporting plate;
[0009] The pressing plate is attached to the outer surface of the nut of the strain clamp body, the limiting column is fixed on the outer surface of the strain clamp body, the limiting plate is fixed on the outer surface of the pressing plate, the limiting column is located inside the limiting plate, the supporting plate is fixed on the outer surface of the limiting plate, there are two groups of supporting plates in total, and the connecting column is movably connected to the inside of one end of the supporting plate and the limiting column.
[0010] Further, a connecting rod is movably connected to the inside of the other end of the supporting plate, and the outer surface of the connecting rod is fixed to the outer surface of the connecting column.
[0011] Further, a connecting shaft is fixed on the outer surface of the connecting column, and a rotating block is rotatably connected to the outer surface of the connecting shaft.
[0012] Further, limiting grooves are formed inside one end of the support plate and inside the limiting posts, and the shape of the limiting grooves is the same as that of the rotating blocks.
[0013] Further, a limiting assembly is further included, and the limiting assembly includes a support frame, a guide rod, and a limiting block;
[0014] Wherein, the support frame is fixed on the upper surface of one end of the support plate, the guide rod is movably connected inside the support frame, the limiting block is fixed on the lower surface of the guide rod, and the limiting block is located inside the rotating block.

[0016] Compared with the prior art, the advantages of the present utility model are as follows:
[0017] First, in the present utility model, through the provided reinforcement assembly, when the strain clamp body is installed at the required position, the limiting plate is aligned with the limiting post, a downward pressing force is applied to the pressing plate, so that the lower surface of the pressing plate fits with the nut of the strain clamp body, the limiting plate passes through the limiting post, and then the connecting column is inserted into the support plate. The inner part makes the connecting rod fit with the outer surface of the support plate. Under the action of the connecting shaft, a rotating force is applied to the rotating block, so that the protruding position of the rotating block is directly below the support frame. This scheme makes the nut more stably fixed at the required position, and the overall structure is more firm and reliable.
[0018] Second, based on the first beneficial effect, when it is necessary to insert the connecting column, an upward force is applied to the guide rod to make the spring in a compressed state. When the protruding position of the rotating block is directly below the support frame, the force applied to the guide rod is cancelled. Under the elastic force of the spring, the limiting block moves downward after being released from the force, so that the limiting block is inserted into the rotating block. This scheme can stably fix the rotating block at the required position, thereby making the connecting column stably fixed inside the support plate and the limiting post.

[0032] Strain clamp body 11;
[0033] Reinforcement component, the reinforcement component includes a pressing plate 21, a limit post 22, a limit plate 23, a connecting post 25, and a support plate 29;
[0034] The pressing plate 21 is attached to the outer surface of the nut of the strain clamp body 11. The limit post 22 is fixed on the outer surface of the strain clamp body 11. The limit plate 23 is fixed on the outer surface of the pressing plate 21. The limit post 22 is located inside the limit plate 23. The support plate 29 is fixed on the outer surface of the limit plate 23. There are two groups of support plates 29 in total. The connecting post 25 is movably connected to one end of the support plate 29 and the inside of the limit post 22, and the other end is movably connected to the inside of the support plate 29. The connecting rod 24 is fixed to the outer surface of the connecting post 25;
[0035] The pressing plate 21 is used to limit the nut, so that the thread is more stably fixed at the required position. The limiting column 22 is used to receive and install the limiting plate 23, so as to fix the pressing plate 21 to the required position. The connecting column 25 is used to be fixed inside the support plate 29 and the limiting column 22, so as to stably fix the limiting plate 23 outside the limiting column 22;
[0036] A connecting shaft 26 is fixed on the outer surface of the connecting column 25, and a rotating block 27 is rotatably connected to the outer surface of the connecting shaft 26;
[0037] The connecting shaft 26 is used for the rotating block 27 to rotate on its surface, and the rotating block 27 is used to limit the connecting column 25 inside the support plate 29 and the limiting column 22;
[0038] Limiting grooves 28 are provided inside one end of the support plate 29 and the limiting column 22, and the shape of the limiting grooves 28 is the same as that of the rotating block 27;
[0039] The limiting grooves 28 are used for the connecting column 25 to pass through the inside of the support plate 29 and the limiting column 22;
[0040] When the strain clamp body 11 is installed at the required position, align the limiting plate 23 with the limiting column 22, apply a downward pressing force to the pressing plate 21, so that the lower surface of the pressing plate 21 fits the nut of the strain clamp body 11. The limiting plate 23 passes through the limiting column 22, and then insert the connecting column 25 into the inside of the support plate 29, so that the connecting rod 24 fits the outer surface of the support plate 29. Under the action of the connecting shaft 26, apply a rotating force to the rotating block 27, so that the protruding position of the rotating block 27 is directly below the support frame 31;
[0041] This step makes the nut more stably fixed at the required position, and the overall structure is more firm and reliable.
[0042] Please refer to Figures 1 - 4 As shown, based on the above-mentioned Embodiment 1, this embodiment further includes a limiting component, and the limiting component includes a support frame 31, a guide rod 32 and a limiting block 33;
[0043] Among them, the support frame 31 is fixed on the upper surface of one end of the support plate 29, the guide rod 32 is movably connected inside the support frame 31, the limiting block 33 is fixed on the lower surface of the guide rod 32, and the limiting block 33 is located inside the rotating block 27;

[0046] The spring 34 is used to spring the limit block 33 back to its original position. The protective frame 35 is used to wrap the spring 34 to prevent the spring 34 from being exposed to the wind and sun, which may affect the normal performance of the spring 34;
[0047] When it is necessary to insert the connecting column 25, an upward force is applied to the guide rod 32, so that the spring 34 is in a compressed state. When the protruding position of the rotating block 27 is directly below the support frame 31, the force applied to the guide rod 32 is cancelled. Under the elastic force of the spring 34, the limit block 33 moves downward after being free of force, so that the limit block 33 is inserted into the rotating block 27;
[0048] This step can stably fix the rotating block 27 at the required position, so that the connecting column 25 is stably fixed inside the support plate 29 and the limit column 22.
