Description
Technical Field
[0001] This utility model relates to the field of cable production technology, specifically to a tension clamp. Background Technology
[0002] With the continuous development of the power industry, the requirements for the stability and safety of power transmission are becoming increasingly stringent. In overhead power lines, tension clamps are crucial hardware used to secure cables to power towers to withstand cable tension. Traditional tension clamps suffer from insufficient clamping force during use, which not only affects the stability and safety of power transmission but also increases maintenance costs and workload. Therefore, a new type of tension clamp is needed to solve the problems of traditional tension clamps and improve the stability and safety of power transmission. The tension clamp of this invention was developed in response to this technological background. Utility Model Content
[0003] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a tension clamp, comprising: a hanging plate for connecting the overall device to a supporting structure such as a power tower; a fixing block, the outer wall of which is rotatably connected to the outer wall of the hanging plate; a clamping device, comprising a clamping block and a stabilizing structure, the outer wall of which is slidably connected to the inner wall of the fixing block; a stabilizing device, the outer wall of which is slidably connected to the inner wall of the fixing block; the stabilizing structure comprises an arc-shaped piece, the outer wall of which is slidably connected to the inner wall of the clamping block, a friction plate fixedly connected to the outer wall of the arc-shaped piece, a support rod and a support spring fixedly connected to the side of the arc-shaped piece near the clamping block, the outer wall of which penetrates the support spring and extends to both sides.
[0004] Preferably, the inner wall of the clamping block is provided with a fixing groove and a sliding hole, and the bottom of the clamping block is provided with a stabilizing groove.
[0005] Preferably, the outer wall of the arc-shaped piece is fixedly connected to the fixing groove by a support spring, and the outer wall of the support rod is slidably connected to the sliding hole.
[0006] Preferably, the stabilizing device includes a stabilizing upright, the outer wall of which is slidably connected to the inner wall of the fixing block, a stabilizing crossbar fixedly connected to the side wall of the stabilizing upright, a stabilizing block fixedly connected to the outer wall of the stabilizing upright, and a stabilizing spring fixedly connected to the bottom of the stabilizing block.
[0007] Preferably, the inner wall of the fixing block is provided with a stabilizing hole, a first locking groove and a second locking groove, and the stabilizing rod passes through the stabilizing hole and the stabilizing spring.
[0008] Preferably, the outer wall of the stabilizing block is slidably connected to the inner wall of the fixing block, the stabilizing block matches the stabilizing groove, and both the fixing block and the clamping block adopt a wedge-shaped structure. The wedge-shaped structure design of the fixing block and the clamping block makes the contact increasingly tight during the insertion process, which can effectively squeeze the clamping block and make the clamping block tightly press the internal cable.
[0009] The beneficial effects of this utility model are as follows:
[0010] 1. The wedge-shaped structure design of the fixing block and clamping block in this utility model ensures increasingly tight contact during insertion, effectively squeezing the clamping block and firmly pressing it against the internal cable, thus increasing the clamping force on the cable. The stabilizing structure in the clamping device further enhances the cable fixing effect. The support spring tightly presses the arc-shaped plate against the cable, and the friction plate on the arc-shaped plate is in close contact with the cable. The friction between the two effectively restricts the movement of the cable, improving the stability of the cable fixing.
[0011] 2. This utility model, by setting a stabilizing device, has a stabilizing block in the stabilizing device that, under the action of a stabilizing spring, inserts into the stabilizing groove when the clamping block is inserted into the fixing block, thus locking the clamping block and preventing it from loosening or falling out during use. This further improves the stability of the tension clamp, thereby ensuring the stability and safety of power transmission. When it is necessary to remove the clamping block, the stabilizing block can be disengaged from the clamping block by pulling down the stabilizing pole or rotating it. This design makes the tension clamp more stable. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose. Example
[0020] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a tension clamp, comprising: a hanging plate 1 for connecting the overall device to a supporting structure such as a power tower; a fixing block 3, the outer wall of which is rotatably connected to the outer wall of the hanging plate 1; a clamping device 4, which includes a clamping block 41 and a stabilizing structure 42, the outer wall of which is slidably connected to the inner wall of the fixing block 3; a stabilizing device 5, the outer wall of which is slidably connected to the inner wall of the fixing block 3; the stabilizing structure 42 includes an arc-shaped piece 421, the outer wall of which is slidably connected to the inner wall of the clamping block 41, a friction piece 422 fixedly connected to the outer wall of the arc-shaped piece 421, a support rod 424 and a support spring 423 fixedly connected to the side of the arc-shaped piece 421 near the clamping block 41, the outer wall of which passes through the support spring 423 and extends to both sides.
[0021] The inner wall of the clamping block 41 is provided with a fixing groove 412 and a sliding hole 413. The bottom of the clamping block 41 is provided with a stabilizing groove 414. In order to prevent the cable from loosening, the stabilizing structure 42 in the clamping device 4 will once again play a stabilizing role for the cable. At this time, the support spring 423 is fixed on the fixing groove 412. The support spring 423 tightly presses the arc-shaped piece 421 against the cable. The friction piece 422 on the arc-shaped piece 421 is also pressed against the cable. The friction between the two effectively restricts the movement of the cable. In order to stabilize the arc-shaped piece 421, a support rod 424 is fixedly connected to the outer wall of the arc-shaped piece 421. The support rod 424 slides inside the sliding hole 413.
[0022] The outer wall of the arc-shaped piece 421 is fixedly connected to the fixing groove 412 by the support spring 423, and the outer wall of the support rod 424 is slidably connected to the sliding hole 413.
[0023] The stabilizing device 5 includes a stabilizing pole 52, the outer wall of the stabilizing pole 52 is slidably connected to the inner wall of the fixing block 3, a stabilizing crossbar 54 is fixedly connected to the side wall of the stabilizing pole 52, a stabilizing block 51 is fixedly connected to the outer wall of the stabilizing pole 52, and a stabilizing spring 53 is fixedly connected to the bottom of the stabilizing block 51.
[0024] The inner wall of the fixing block 3 is provided with a stabilizing hole 31, a first locking groove 32, and a second locking groove 33. The stabilizing rod 52 passes through the stabilizing hole 31 and the stabilizing spring 53. In order to prevent the wire clamping block 41 from loosening or falling out during use, the stabilizing block 51 in the stabilizing device 5 can be effectively inserted into the stabilizing groove 414 under the action of the stabilizing spring 53 during the insertion of the wire clamping block 41 into the fixing block 3, thereby achieving the effect of locking the wire clamping block 41. When the wire clamping block 41 needs to be pulled out, the stabilizing rod 52 is pulled down, so that the stabilizing rod 52 slides in the stabilizing hole 31. At the same time, the stabilizing crossbar 54 slides in the first locking groove 32. Then, the stabilizing rod 52 is rotated, so that the stabilizing crossbar 54 is locked in the second locking groove 33. At this time, the stabilizing block 51 is disengaged from the wire clamping block 41, so that the wire clamping block 41 can be pulled out, which is convenient for the next step of work.
[0025] The outer wall of the stabilizing block 51 is slidably connected to the inner wall of the fixing block 3. The stabilizing block 51 matches the stabilizing groove 414. Both the fixing block 3 and the clamping block 41 adopt a wedge-shaped structure.
[0026] Working principle:
[0027] In use, the mounting plate 1 is fixed to the power tower by fastening bolts. The end of the mounting plate 1 away from the power tower is rotatably connected to the fixing block 3. Then, the cable is placed inside the clamping device 4, and the clamping device 4 is inserted into the fixing block 3. Since both the fixing block 3 and the clamping block 41 in the clamping device 4 are wedge-shaped structures, the contact between the fixing block 3 and the clamping block 41 will become tighter and tighter during the insertion process, thereby squeezing the clamping block 41. The clamping block 41 squeezes the cable inside, which plays a role in stabilizing the cable.
[0028] To prevent the cable from loosening, the stabilizing structure 42 in the clamping device 4 will again stabilize the cable. At this time, the support spring 423 is fixed on the fixing groove 412. The support spring 423 tightly presses the arc-shaped plate 421 against the cable. The friction plate 422 on the arc-shaped plate 421 is also pressed against the cable. The friction between the two effectively restricts the movement of the cable. In order to stabilize the arc-shaped plate 421, a support rod 424 is fixedly connected to the outer wall of the arc-shaped plate 421. The support rod 424 slides inside the sliding hole 413.
[0029] To prevent the wire clamping block 41 from loosening or coming off during use, the stabilizing block 51 in the stabilizing device 5 can be effectively inserted into the stabilizing groove 414 under the action of the stabilizing spring 53 during the insertion of the wire clamping block 41 into the fixing block 3, thereby achieving the effect of locking the wire clamping block 41. When the wire clamping block 41 needs to be pulled out, the stabilizing upright 52 is pulled down, causing the stabilizing upright 52 to slide in the stabilizing hole 31. At the same time, the stabilizing horizontal bar 54 slides inside the first locking groove 32. Then, the stabilizing upright 52 is rotated, causing the stabilizing horizontal bar 54 to be locked inside the second locking groove 33. At this time, the stabilizing block 51 is disengaged from the wire clamping block 41, allowing the wire clamping block 41 to be pulled out, facilitating the next step of the work.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
