Description

Technical Field

[0001] This utility model relates to the field of wire clamps, and in particular to anti-loosening wedge wire clamps. Background Technology

[0002] Wedge clamps are fastening tools commonly used in the installation of power, communication and other lines. They are mainly used to connect cables or wires by clamping the cable with a wedge-shaped structure to ensure a firm and reliable connection.

[0003] When clamping cables, the cable is passed through the clamping plate, and then the wedge block is moved to insert into the clamping plate. The wedge block and the clamping plate then work together to clamp the cable. A fixing bolt is then used to pass through the clamping plate, and a nut is threaded onto the fixing bolt surface to fix the clamping plate in position. This is how the wedge clamp is used. However, during use, the wedge block is prone to shifting under force, causing loosening between the wedge block and the cable. This reduces the clamping force of the wedge block, thus affecting the effectiveness of the wedge clamp. Utility Model Content

[0004] The technical problem this utility model aims to solve is that when the wedge block is in use, it is easily moved by force, which causes loosening between the wedge block and the cable, resulting in a reduction in the clamping force of the wedge block on the cable, thus affecting the performance of the wedge clamp.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an anti-loosening wedge clamp, including a clamp plate, a fixing bolt on one side of the clamp plate, a nut threaded into one side of the fixing bolt, a wedge block inserted inside the clamp plate, and an anti-loosening device on one side of the clamp plate, wherein the anti-loosening device limits the wedge block by means of a limiting block.

[0006] Preferably, the anti-loosening device includes a placement frame, a limiting block, and a spring. The placement frame is disposed on one side of the clamping plate, and the limiting block is inserted into one side of the placement frame to limit the wedge block. The two ends of the spring are respectively connected to the placement frame and the limiting block to drive the limiting block to reset.

[0007] Preferably, an auxiliary component is provided on one side of the placement rack to block the position of the limiting block.

[0008] Preferably, the auxiliary component includes an auxiliary block that passes through the placement frame and is located on one side of the limiting block to block the position of the limiting block.

[0009] Preferably, the magnet is placed on the side of the placement rack near the auxiliary block, and the iron block is placed on the side of the auxiliary block near the magnet, so as to attract the magnet.

[0010] Preferably, a telescopic rod is sleeved inside the spring, and the two ends of the telescopic rod are respectively connected to a limiting block and a placement frame to restrict the shape of the spring.

[0011] Preferably, the anti-loosening device includes a drive bolt, which is threadedly inserted into the placement frame. One side of the drive bolt is rotatably connected to the limiting block to drive the limiting block to move.

[0012] Preferably, the placement rack has an inclined groove on the side near the limiting block, and the inclined groove area on the side of the limiting block near the placement rack is provided with a stabilizing plate, and one side of the stabilizing plate is slidably connected to the sliding groove on the surface of the placement rack.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] By using an anti-loosening device, a limiting block can be used to restrict the position of the wedge block, preventing it from easily moving under force during use, which could cause loosening between the wedge block and the cable, and reduce the clamping force of the wedge block on the cable, thereby improving the performance of the wedge clamp.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Example 1,

[0026] Figures 1 to 4 The anti-loosening wedge clamp shown includes a clamping plate 1, a fixing bolt 2 on one side of the clamping plate 1, a nut 3 threaded into one side of the fixing bolt 2, a wedge block 4 inserted inside the clamping plate 1, and an anti-loosening device 5 on one side of the clamping plate 1. The anti-loosening device 5 limits the wedge block 4 through a limiting block 52. When clamping a cable, the cable is passed through the clamping plate 1, and then the wedge block 4 is moved to insert into the clamping plate 1. The wedge block 4 and the clamping plate 1 then cooperate to clamp the cable. At this time, the anti-loosening device 5 is used to limit the wedge block 4. Then, the fixing bolt 2 is used to pass through the clamping plate 1, and the nut 3 is threaded onto the surface of the fixing bolt 2 to fix the position of the clamping plate 1, and then the wedge clamp is used.

[0027] Figures 1 to 4 The anti-loosening device 5 shown includes a placement frame 51, a limiting block 52, and a spring 53. The placement frame 51 is set on one side of the clamping plate 1, and the limiting block 52 is inserted on one side of the placement frame 51 to limit the wedge block 4. The two ends of the spring 53 are connected to the placement frame 51 and the limiting block 52 respectively to drive the limiting block 52 to reset.

[0028] Figures 1 to 4As shown, before the wedge block 4 is inserted into the clamping plate 1 to clamp and fix the cable, the limiting block 52 is moved so that the limiting block 52 moves inside the placement frame 51, and the limiting block 52 drives the spring 53 fixed on one side to compress. Then, when the wedge block 4 is inserted into the clamping plate 1 to clamp and fix the cable, the wedge block 4 will pass through the limiting block 52, and then the limiting block 52 is released, so that the spring 53 fixed to the placement frame 51 and the limiting block 52 resets, thereby driving the limiting block 52 to limit the position of the wedge block 4, preventing the wedge block 4 from moving under force, which would cause the wedge block 4 and the cable to become loose. By using the anti-loosening device 5, the position of the wedge block 4 is restricted, preventing the wedge block 4 from easily moving under force during use, which would cause the wedge block 4 and the cable to become loose, and thus reduce the clamping force of the wedge block 4 on the cable, thereby improving the use effect of the wedge clamp.

[0029] Figures 1 to 4 An auxiliary component 54 is provided on one side of the placement rack 51 to block the position of the limiting block 52. The auxiliary component 54 includes an auxiliary block 541, which passes through the placement rack 51 and is located on one side of the limiting block 52 to block the position of the limiting block 52. When the limiting block 52 is in use, the auxiliary block 541 passes through the placement rack 51 and is located at the upper end of the limiting block 52 to prevent the limiting block 52 from moving away from the wedge block 4, thus keeping the limiting block 52 in a position that limits the wedge block 4. When the limiting block 52 is not in use, the auxiliary block 541 is located on the side of the limiting block 52 away from the spring 53 to block the limiting block 52 and prevent the limiting block 52 from being reset by the spring 53.

[0030] Figures 1 to 4 The magnet 542 is positioned on the side of the placement frame 51 near the auxiliary block 541, and the iron block 543 is positioned on the side of the auxiliary block 541 near the magnet 542 to attract the magnet 542. When using the auxiliary block 541, the magnet 542 fixed on one side of the placement frame 51 attracts the iron block 543 fixed on the same side, making the auxiliary block 541 more stable to use. A telescopic rod 55 is fitted inside the spring 53. The two ends of the telescopic rod 55 are connected to the limiting block 52 and the placement frame 51, respectively, to restrict the shape of the spring 53. By fitting the telescopic rod 55 inside the spring 53 and fixing its two ends to the limiting block 52 and the placement frame 51, the shape of the spring 53 is restricted, preventing the spring 53 from bending under force and affecting its reset function.

[0031] Working principle: When clamping the cable, the cable is passed through the clamping plate 1, and then the wedge block 4 is moved to insert into the clamping plate 1. The wedge block 4 and the clamping plate 1 cooperate to squeeze and clamp the cable. At this time, the anti-loosening device 5 is used to limit the wedge block 4. Then, the fixing bolt 2 is used to pass through the clamping plate 1, and then the nut 3 is threaded onto the surface of the fixing bolt 2 to fix the position of the clamping plate 1. Then the wedge cable clamp is used. Before the wedge block 4 is inserted into the clamping plate 1 to clamp and fix the cable, the limiting block 52 is moved so that the limiting block 52 moves inside the placement frame 51 and causes the limiting block 52 to compress the spring 53 fixed on one side. When the wedge block 4 is inserted into the clamping plate 1 to clamp and fix the cable, the wedge block 4 will pass through the limiting block 52 and then release the limiting block 52, causing the spring 53 fixed to the placement frame 51 and the limiting block 52 to reset, thereby causing the limiting block 52 to limit the position of the wedge block 4 and prevent the wedge block 4 from moving under force, which would cause the wedge block 4 and the cable to become loose. By using the anti-loosening device 5, the position of the wedge block 4 is restricted, preventing the wedge block 4 from moving under force during use, which would cause the wedge block 4 and the cable to become loose, and thus reduce the clamping force of the wedge block 4 on the cable, thereby improving the use effect of the wedge clamp.

[0032] Example 2,

[0033] Figures 5 to 6 The anti-loosening device 5 shown includes a drive bolt 56, which is threadedly inserted into the placement frame 51. One side of the drive bolt 56 is rotatably connected to the limiting block 52 to drive the limiting block 52 to move. The placement frame 51 is fixed to the upper end of the clamping plate 1. The drive bolt 56 is threadedly inserted into the placement frame 51, and one side of the placement frame 51 is rotatably connected to the limiting block 52. Then, the drive bolt 56 rotates to move the limiting block 52 to one side of the placement frame 51, and moves the limiting block 52 to the side of the wedge block 4 to limit the position of the wedge block 4.

[0034] Figures 5 to 6 The placement frame 51 shown has an inclined groove on the side near the limiting block 52. The limiting block 52 has a stabilizing plate 58 in the inclined groove area on the side near the placement frame 51. One side of the stabilizing plate 58 is slidably connected to the sliding groove 57 on the surface of the placement frame 51. By fixing the stabilizing plate 58 to one side of the limiting block 52 and sliding the stabilizing plate 58 in the sliding groove 57 on the surface of the placement frame 51, the movement trajectory of the limiting block 52 is restricted, so that the limiting block 52 can move more stably.

[0035] Working principle: The placement frame 51 is fixed on the upper end of the clamping plate 1. The drive bolt 56 is threaded into the placement frame 51, and one side of the placement frame 51 is rotatably connected to the limiting block 52. Then the drive bolt 56 rotates to drive the limiting block 52 to move on one side of the placement frame 51. At this time, the stabilizing plate 58 slides in the sliding groove 57 on the surface of the placement frame 51 to limit the movement trajectory of the limiting block 52. Then the limiting block 52 is moved to the wedge block 4 to limit the position of the wedge block 4.
