Description

Technical Field

[0001] The utility model relates to the field of limit clamps, in particular to a limit clamp for facilitating the maintenance of cables. Background Art

[0002] At present, the Chinese utility model with the publication number of CN212726405U discloses a new type of cable clamp for quick clamping, especially related to the technical field of cable clamps. An arc-shaped plate is arranged inside the clamping groove, a clamping plate is arranged inside the arc-shaped frame, a connecting seat is fixed at the upper end of the clamping plate, a lead screw is rotatably connected to the upper end of the connecting seat, the upper end of the lead screw penetrates through the arc-shaped frame and is in threaded connection with the arc-shaped frame, and an upper arc-shaped plate is fixed on the inner wall of the clamping plate. For this new type of cable clamp for quick clamping, by placing the leaky cable into the clamping groove and then rotating the lead screw, the clamping plate can be driven to move, so that the clamping plate and the clamping groove cooperate to clamp the leaky cable, and the operation is more convenient; when the clamping plate moves towards the base, the limiting rod will be driven to insert into the side cavity, so that the sliding rod will drive the lower arc-shaped plate to move, and the lower arc-shaped plate and the upper arc-shaped plate cooperate to quickly clamp the leaky cable, solving the problem that the clamping speed of the current cable clamp is slow, resulting in a slow overall installation work.

[0003] Although the existing limit clamps can press the cable through the clamping plate and the clamping groove, there are still other problems in the use process. For example, the position of the cable cannot be moved after being fixed. Since the clamp is directly fixed on the wall with screws during installation, when the position of the clamp is deviated after being fixed, it is necessary for personnel to remove the clamp and re-drill holes for fixing, which is cumbersome and complex. Moreover, it is not convenient to quickly place and remove the cable. The cable needs to pass through the center of the clamp after being placed. When the cable needs to be removed for maintenance, it is necessary to separate the clamping plate from the clamping groove. During the outward movement of the clamping plate, it is necessary to use tools to rotate the lead screw, reducing the maintenance efficiency of personnel for the cable. To solve the above problems, we propose a limit clamp for facilitating the maintenance of cables. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a limit clamp for facilitating the maintenance of cables, which solves the problems that the existing limit clamps are not convenient to adjust the height of the cable and are more cumbersome when placing, removing and maintaining the cable.

[0005] The above technical object of the utility model is achieved by the following technical solutions: A limit clamp for facilitating the maintenance of cables, including a fixed frame, a fixed frame is provided with a fixed frame on one side, a threaded rod is welded to the side of the fixed frame close to the fixed frame, and the other end of the threaded rod penetrates and extends into the interior of the fixed frame. The surface of the threaded rod is threadedly connected with a fixing nut. A sliding groove is opened on one side of the fixed frame, a limiting U-shaped plate penetrates through one side of the fixed frame, two through grooves are opened on one side of the fixed frame, an arc-shaped groove is opened inside the limiting U-shaped plate, and a fixing plate is welded inside the limiting U-shaped plate. A limiting spring is bolted between one side of the fixing plate and the fixed frame through a spring fixing piece.

[0006] Adopting the above technical solution, it can have a height adjustment function, the number of clamps can be increased or decreased according to the situation, reducing the burden of repeated and multiple punching for personnel.

[0009] The utility model is further arranged as follows: An installation hole is opened on the other side of the fixed frame.

[0010] Adopting the above technical solution, through the setting of the installation hole, it is convenient for personnel to fix the fixed frame on the wall with screws.

[0011] The utility model is further arranged as follows: A pulling plate is welded to the other side of the limiting U-shaped plate.

[0012] Adopting the above technical solution, through the setting of the pulling plate, it is convenient for personnel to pull the limiting U-shaped plate outwards.

[0013] The utility model is further arranged as follows: A rubber pad is bonded to the surface of the arc-shaped groove inside the limiting U-shaped plate.

[0014] Adopting the above technical solution, through the setting of the rubber pad, the cable can be protected to avoid damage to the insulating sleeve of the cable when the limiting U-shaped plate is pressed.

[0015] The utility model is further arranged as follows: The threaded rod and the fixing nut are both made of stainless steel.

[0016] With the above technical solution, the threaded rod and the fixing nut have the characteristics of high strength, low density, and excellent corrosion resistance.

[0017] The present utility model is further configured such that: the limiting spring is made of carbon spring steel.

[0018] With the above technical solution, the limiting spring has the characteristics of excellent mechanical properties, good anti-spring reduction performance, low-temperature resistance, and corrosion resistance.

[0019] In summary, the present utility model has the following beneficial effects:

[0020] 1. In the present utility model, first, the fixing frame is fixed at the designated position with screws. After the fixing frame is fixed, the fixing frame is picked up. After the fixing frame is picked up, the fixing nut is screwed onto the left end of the surface of the threaded rod. Then, the threaded rod is placed in the sliding groove and slides downward. When the fixing frame slides down to an appropriate height, the fixing nut is tightened. Finally, other fixing frames are placed in turn. It can have a height adjustment function, can increase or decrease the number of clamps according to the situation, and reduces the burden of repeated and multiple punching by personnel.

[0021] 2. In the present utility model, by grasping the pull plate and pulling it outward, when the pull plate is pulled outward, it will drive the limiting U-shaped plate and the fixing plate to move outward. When the fixing plate moves, it will press the limiting spring into a contracted state. When the pull plate is pulled out to the end, the cable is inserted through the arc-shaped groove in the limiting U-shaped plate. Finally, the hand holding the pull plate is released. Since the pull plate has elasticity, after the pull plate returns to its original position, it will drive the limiting U-shaped plate to clamp the cable, which is convenient for personnel to place and take the cable for maintenance, has simple and convenient operation, improves the work efficiency of personnel, and has high practicability.
