Description

Technical Field

[0001] The utility model relates to the technical field of electric power hardware, in particular to an anti-theft UT wire clamp. Background Art

[0002] The electric poles on the transmission lines are usually provided with a plurality of inclined steel strands, one end of which is fixed to the middle of the electric pole, and the other end is fixed to the ground through a UT wire clamp, so as to ensure that the electric pole remains upright and does not tilt when subjected to external force. Patent application number 97209257.9 discloses an anti-theft UT wire clamp, which is provided with a notch on the side wall of the U-shaped screw rod head suitable for the nut to be compressed and deformed therein. When in use, the nut 5 is screwed to the notch, and then the nut 5 is flattened along the notch with a hydraulic pliers, so as to achieve the purpose of anti-theft. However, at this time, the nut 3 can be screwed in the direction of the notch, and it is possible that an idle person will loosen the nut 3, thereby loosening the steel strand, causing the electric pole to tilt when subjected to external force. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an anti-theft UT wire clamp in view of the above-mentioned technical deficiencies.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: an anti-theft UT wire clamp, including a U-bolt, a wire clamp body sleeved on the U-bolt, a first nut and a second nut threadedly connected on the U-bolt, a concave platform is provided on the side of the second nut away from the wire clamp body, and also includes a retaining ring, a threaded hole is provided on the retaining ring and is threadedly connected to the U-bolt, the retaining ring can be located in the concave platform and its height is not greater than the depth of the concave platform, the outside of the retaining ring does not contact the side wall of the concave platform, the retaining ring is provided with a socket, and a pin is slidably connected in the socket, and when the outer end of the pin is flush with the side of the retaining ring away from the wire clamp body, it cannot be further inserted into the socket.

[0005] Preferably, the insertion hole is a through hole, and the height of the pin is equal to the height of the retaining ring.

[0006] Preferably, the insertion hole is a blind hole, and the height of the pin is equal to the depth of the insertion hole.

[0007] Preferably, the retaining ring is truncated cone-shaped.

[0008] Preferably, the second nut is located on a side of the first nut away from the clamp body.

[0009] Preferably, the device further comprises a gasket, which is sleeved on the outside of the U-bolt and located on a side of the wire clamp body close to the first nut.

[0010] Compared with the prior art, the utility model has the following advantages: a recess is provided on the second nut, and the retaining ring threadedly connected to the U-bolt can completely enter the recess and press against the bottom surface of the recess; the retaining ring is also provided with an insertion hole and a pin inserted therein; when the pin is completely knocked into the insertion hole, the outer end of the pin is flush with the side of the retaining ring away from the wire clamp body; at this time, the retaining ring completely located in the recess is difficult to be twisted, so that the second nut cannot be twisted toward the side where the retaining ring is located, and it is basically impossible to be loosened by idle people, and it cannot be removed from the U-bolt.

[0014] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0015] Specific implementation method: Combination Figure 1-2As shown, an anti-theft UT wire clamp includes a U-bolt 1, a wire clamp body 2 is sleeved on the U-bolt 1, the wire clamp body 2 includes a wedge sleeve and a wedge, and a first nut 4 and a second nut 5 are threadedly connected to the U-bolt 1. The second nut 5 is provided with a recessed platform on the side away from the wire clamp body 2, and also includes a retaining ring 6, the retaining ring 6 is provided with a threaded hole and is threadedly connected to the U-bolt 1, the retaining ring 6 can be located in the recessed platform and its height is not greater than the depth of the recessed platform, the outside of the retaining ring 6 does not contact the side wall of the recessed platform, the retaining ring 6 is provided with a socket 61, and a pin 7 is slidably connected in the socket 61, and the pin 7 is preferably tightly matched with the socket 61 so that it will not be relative to the socket 6 under the action of gravity. 1 slides, when the retaining ring 6 is turned, a part of the pin 7 is exposed outside the insertion hole 61, so that the retaining ring 6 can be completely screwed into the concave platform and pressed against the bottom surface of the concave platform by moving the pin 7. After the retaining ring 6 presses against the bottom surface of the concave platform, the pin 7 can be completely knocked into the insertion hole 61. When the outer end of the pin 7 is flush with the side of the retaining ring 6 away from the wire clamp body 2, it cannot be further inserted into the insertion hole 61, so that this side of the retaining ring 6 is a plane, so there is no force, and it is not easy to rotate the retaining ring 6. After the position of the wire clamp body 2 on the U-bolt 1 is adjusted, the retaining ring 6 is completely screwed into the concave platform and pressed against the bottom surface of the concave platform. At this time, the second nut 5 cannot be screwed to the side where the retaining ring 6 is located, and it is basically impossible to be loosened by an idle person, and it cannot be removed from the U-bolt 1.

[0016] As an embodiment of the present application, the socket 61 is a through hole, and the height of the pin 7 is equal to the height of the retaining ring 6. When the retaining ring 6 is pressed against the bottom surface of the recess, the pin 7 is completely knocked into the socket 61 and its outer end is flush with the side of the retaining ring 6 away from the wire clamp body 2.

[0017] As another embodiment of the present application, the socket 61 is a blind hole, the height of the pin 7 is equal to the depth of the socket 61, and after the pin 7 is completely knocked into the socket 61, its outer end is flush with the side of the retaining ring 6 away from the wire clamp body 2.

[0018] Preferably, the retaining ring 6 is in a truncated cone shape, and the end with a smaller diameter is close to the bottom surface of the recess. The diameter of the bottom surface with a smaller diameter should be slightly larger than the outer diameter of the threaded hole, so that the contact area between the inner end of the retaining ring 6 and the bottom surface of the recess is smaller, thereby preventing the retaining ring 6 from rotating together when the second nut 5 is rotated.

[0019] Preferably, the second nut 5 is located on a side of the first nut 4 away from the wire clamp body 2. In this case, the first nut 4 and the second nut 5 can be tightened first, and then the retaining ring 6 can be tightened.

[0020] Preferably, the device further comprises a gasket 3, which is sleeved on the outside of the U-bolt 1 and located on a side of the wire clamp body 2 close to the first nut 4, so that the wire clamp body 2 is not easily scratched when the first nut 4 is rotated.

[0021] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
