DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, the present utility model provides a technical solution: an adjustable suspension clamp, including the main body 1 of the suspension clamp and a limiting component for fixing the wire. The limiting component includes limiting blocks 21 respectively arranged on both sides inside the main body 1, a limiting opening 22 opened on one side of the limiting block 21, a moving frame 23 fixedly connected to one side of the limiting block 21, a screw rod 24 connected to the moving frame 23, a fixed disk 25 fixedly connected to the outer side of the screw rod 24, a plurality of card slots 26 arranged in a circular pattern on the outer side of the fixed disk 25, fixed blocks 27 respectively fixedly connected to both sides of the main body 1, a moving opening 28 opened at the top of the fixed block 27, a clamping rod 29 connected to the moving opening 28, a fixed ring 30 fixedly connected to the outer side of the clamping rod 29, a first spring 31 fixedly connected to the top of the fixed ring 30, and a protection component for protecting the wire. The screw rod 24 is rotatably connected to the main body 1, and the screw rod 24 is screwed to the moving frame 23. The wire can pass through the main body 1. By pulling the clamping rod 29 to disengage it from the card slot 26, the fixed disk 25 and the screw rod 24 can be released. Rotating the screw rod 24 can drive the moving frame 23 to move, and then drive the limiting block 21 to move. The two limiting blocks 21 can position and fix wires of different sizes. The clamping rod 29 can be snapped into the card slot 26 under the push of the spring, locking the screw rod 24, thereby preventing the limiting block 21 from moving away from the wire and preventing the wire from moving, resulting in wire wear and improving the fixing performance of the wire. On both sides inside the main body 1, there are respectively fixedly connected with anti-rotation rods 51. One end of the anti-rotation rod 51 is fixedly connected with a limiting plate 52. The anti-rotation rod 51 passes through the moving frame 23 and is slidably connected to the moving frame 23. The anti-rotation rod 51 can limit the movement of the moving frame 23, preventing the moving frame 23 from rotating synchronously with the screw rod 24 and ensuring the lateral movement stability of the moving frame 23 and the limiting block 21. On both sides inside the moving opening 28, there are respectively opened with protection grooves 71. On both sides of the clamping rod 29, there are respectively fixedly connected with protection plates 72. The protection plates 72 are slidably connected to the protection grooves 71. The clamping rod 29 can drive the protection plates 72 to move, and the protection plates 72 can prevent the clamping rod 29 from rotating, thereby protecting the first spring 31 and preventing the first spring 31 from being damaged by rotation. One end of the screw rod 24 is fixedly connected with a twisting plate 81, and the other end of the screw rod 24 is fixedly connected with a baffle plate 82. The twisting plate 81 can facilitate driving the screw rod 24 to rotate, facilitating fixing or releasing the wire. The baffle plate 82 can limit the moving distance of the moving frame 23, preventing the moving frame 23 from disengaging from the screw rod 24. On the outer side of the twisting plate 81, there are a plurality of concave openings 91 arranged in a circular pattern. The concave openings 91 can facilitate gripping, and then facilitate driving the twisting plate 81 to rotate and conveniently controlling the position of the limiting block 21.
[0024] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5, the protective component includes an elastic groove 41 formed on one side inside the limiting opening 22, a ejector rod 42 disposed in the elastic groove 41, a second spring 43 fixedly connected to one end of the ejector rod 42, and a positioning plate 44 fixedly connected to the other end of the ejector rod 42. The ejector rod 42 is slidably connected to the elastic groove 41, and the positioning plate 44 can contact the wire. Due to the presence of the wire, the positioning plate 44 can drive the ejector rod 42 to move. The ejector rod 42 can compress the second spring 43 to deform it. By utilizing the elasticity of the second spring 43, the wire can be restricted and fixed, and at the same time, the wire can be elastically protected to prevent the wire from being damaged. Limiting grooves 61 are respectively formed on both sides inside the limiting opening 22. Limiting rods 62 are respectively fixedly connected to both sides of the positioning plate 44. The limiting rods 62 are slidably connected to the limiting grooves 61. The positioning plate 44 can drive the limiting rods 62 to slide in the limiting grooves 61, which can limit the moving distance of the positioning plate 44, and thus prevent the second spring 43 from being damaged after excessive deformation.
[0025] Working principle: During operation, pass the wire through the main body 1, and then the clamping rod 29 can be pulled to make the clamping rod 29 move. The clamping rod 29 moves out of the current clamping groove 26. At the same time, the clamping rod 29 can drive the moving ring to move. The moving ring moving can compress the first spring 31 to deform it. At this time, the screw rod 24 is released. The twisting plate 81 can be rotated. The twisting plate 81 can drive the screw rod 24 to rotate. The screw rod 24 rotating can drive the moving frame 23 to move. The moving frame 23 moving can drive the limiting block 21 to move. The limiting block 21 moving can contact the wire. At the same time, the positioning plate 44 also contacts the wire. The positioning plate 44 will move in the reverse direction. The positioning plate 44 moving in the reverse direction can drive the ejector rod 42 to move. The ejector rod 42 moving can cause the second spring 43 to deform. The thrust generated by the deformation of the second spring 43 can push the positioning plate 44 to fix the wire. The wire can be stably fixed by using the limiting block 21 and the positioning plate 44. Then release the clamping rod 29. The first spring 31 resetting can drive the clamping rod 29 to snap into the clamping groove 26, which can lock the screw rod 24 to prevent the screw rod 24 from rotating, and thus improve the fixing effect on the wire. The above is the entire working process of the device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
