[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This specific embodiment is an H-type wire clamp with a protective device, and its structural diagram is shown below. Figures 1 to 5As shown, the device includes an upper clamp 1, a lower clamp 2 below the upper clamp 1, and a fixing mechanism 3 installed on the inner side of each of the upper clamp 1 and the lower clamp 2. A protective mechanism 4 is installed on the outer side of each of the upper clamp 1 and the lower clamp 2. The fixing mechanism 3 includes an insert component 31, which is installed on the inner side of each of the upper clamp 1 and the lower clamp 2. The insert component 31 includes a preset groove 311, which is located in the upper middle part of the lower clamp 2. A fixing block 312 is fixedly installed at the bottom of the preset groove 311. An insert block 313 is fixedly installed in the middle of the bottom end of the upper clamp 1, and an insert groove 314 is opened in the lower middle part of the insert block 313. The middle dimension of the insert groove 314 opened in the lower part of the insert block 313 is the same as the outer dimension of the fixing block 312. The mounting block 313 is fitted with first slots 32 on both sides, and second slots 33 are provided on both sides inside the preset slot 311. A stabilizing and limiting component 34 is jointly installed inside the fixing block 312 and on one side of the lower wire clamp 2. The stabilizing and limiting component 34 includes a sliding groove 341, which is symmetrically arranged on both sides of the middle of the fixing block 312. A guide block 342 is slidably provided in the middle of the sliding groove 341, and a return spring 343 is connected to the rear end of the guide block 342. A locking block 344 is fixed above the guide block 342. The end size of the locking block 344 matches the internal opening size of the first slot 32 and the second slot 33. A special-shaped block 345 is fixed inside the locking block 344. A movable opening is provided in the middle of one side of the fixing block 312 and the lower wire clamp 2. A movable guide slot 346 is provided, and a guide rod 347 is movably inserted into the middle of the movable guide slot 346. One end of the guide rod 347 is connected to a movable shaft 348, and the outer end of the movable shaft 348 is connected to a threaded block 349. A threaded bracket 3410 is fixed on the outer wall of the middle part of one side of the lower wire clamp 2. The threaded bracket 3410 and the threaded block 349 are threadedly connected, and the threaded block 349 is movably connected to the guide rod 347 through the movable shaft 348. In use, the personnel first place the wires in the placement slots on both sides of the lower wire clamp 2, and then align and snap the inner insert block 313 of the upper wire clamp 1 into the preset slot 311 provided on the inner side of the lower wire clamp 2 to form an insert state. Then, the guide rod 347 is taken out and follows the lower wire clamp 2 and the fixed block. The guide slot 346 on the same side of 312 is inserted into the center. During the insertion of the guide slot 346 into the fixing block 312, it will contact the three pairs of symmetrical irregular blocks 345 in sequence. Under the pressure of the guide slot 341, the guide block 342 and the elasticity of the return spring 343, the three pairs of irregular blocks 345 will move to both sides, thereby protruding from the corresponding slots on both sides of the fixing block 312. Then, they will be inserted into the first slot 32 and the second slot 33 on both sides of the preset slot 311 of the insert block 313 in sequence. Then, the personnel will thread the threaded block 349 connected to the guide rod 347 by the movable shaft 348 to the center of the threaded bracket 3410 on one side of the lower wire clamp 2. This will achieve stable installation of the upper and lower wire clamps, which is portable and practical.

[0029] The protective mechanism 4 includes a fixed frame 41, which is located on the outside of the upper clamp 1 and the lower clamp 2. An airflow frame 42 is fixed above the multiple fixed frames 41. A rotating rod 43 is installed in the middle of the fixed frame 41, and a driving rod 44 is provided around the rotating rod 43. The fixed frame 41 and the airflow frame 42 are connected, and an airflow groove is provided around the airflow frame 42. When the H-shaped clamp composed of the upper clamp 1 and the lower clamp 2 is put into use, the driving rod 44 in the middle of the airflow frame 42 on the outside of each clamp can rotate adaptively with the airflow under the movement of the rotating rod 43, thereby warning birds in the air and preventing birds from lingering on the clamp, thus providing a certain degree of safety for the clamp and the wire.

[0030] Working principle: During use, the operator first places the wires in the placement slots on both sides of the lower wire clamp 2. Then, the inner mounting block 313 of the upper wire clamp 1 is aligned and inserted into the preset slot 311 on the inner side of the lower wire clamp 2 to form an embedded state. Subsequently, the guide rod 347 is taken out and inserted into the middle of the movable guide slot 346 on the same side as the lower wire clamp 2 and the fixing block 312. During the insertion into the fixing block 312, it will contact the three pairs of symmetrical irregular blocks 345 in sequence. Under the pressure, the three pairs of irregular blocks 345 will move to both sides in conjunction with the sliding groove 341, the guide block 342, and the elasticity of the return spring 343, thereby protruding from the corresponding slots on both sides of the fixing block 312. Then, they are inserted in sequence. The first slot 32 and the second slot 33 on both sides of the pre-set slot 311 are respectively provided on the two sides of the insert block 313. Then, the personnel will thread the threaded block 349 connected to the guide rod 347 by the movable shaft 348 to the middle of the threaded bracket 3410 on the side of the lower clamp 2. This can achieve stable installation of the upper and lower clamps, which is portable and practical. In addition, when the H-type clamp composed of the upper clamp 1 and the lower clamp 2 is put into use, the driving rod 44 in the middle of the airflow frame 42 on the outer side of each clamp can rotate adaptively with the airflow under the movement of the rotating rod 43, thereby warning birds in the air and preventing birds from staying on the clamp for too long, thus providing a certain degree of safety for the clamp and the wire.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
