Description

Technical Field

[0001] The utility model relates to the technical field of cable fixing clamps, in particular to a cable fixing clamp for a large-section cable tunnel. Background Art

[0002] As a common transmission medium, cables are often used to transmit signals between different electrical equipment and are increasingly widely used in power engineering. However, in the specific installation process, in order to facilitate installation, cables are often required to be neatly arranged and multiple cables must be bundled and fixed to avoid scattering.

[0003] In the prior art, traditional cable fixing clamps mostly use bolts to connect the clamps on both sides together to achieve the effect of clamping and fixing the cables. However, this method requires the use of disassembly tools every time during installation and disassembly, which is very inconvenient. In addition, each time the installation bolts need to be disassembled, thread slippage is likely to occur, affecting the fixing effect. Therefore, the utility model proposes a cable fixing clamp for a large-section cable tunnel. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a large-section cable tunnel cable fixing clamp is proposed. By setting a locking mechanism, a movable ring and a spring, the threaded rods on both sides are inserted into the notch, and the lower end of the clamping ring is against the upper end of the second fixed plate in cooperation with the spring and the movable ring, so as to realize locking of the first clamping plate and the second clamping plate. This locking method does not require the use of tools, and the installation and disassembly process is convenient. At the same time, the limiting mechanism can quickly limit the second fixed plate during installation, thereby improving the locking accuracy and thus improving the installation efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The cable fixing clamp of a large-section cable tunnel comprises a first fixing plate and a second fixing plate, the upper end of the first fixing plate is fixedly connected to the first clamping plate, the lower end of the second fixing plate is fixedly connected to the second clamping plate matching the first clamping plate, the upper end of the first fixing plate is provided with two locking mechanisms for locking the first clamping plate and the second clamping plate, the locking mechanism comprises a mounting block fixedly connected to the upper end of the first fixing plate, the upper end of the mounting block is provided with a groove, a rotating rod is rotatably connected between the inner walls at both ends of the groove, a rotating block is fixedly sleeved on the rotating rod, the end of the rotating block is fixedly connected to a threaded rod, a nut is threadedly connected to the threaded rod, and a clamping ring is rotatably connected to one end of the nut close to the mounting block, and a limiting mechanism for limiting the second fixing plate is provided at the upper end of the first fixing plate.

[0007] Preferably, the limiting mechanism comprises four limiting rods distributed in a rectangular shape and fixedly connected to the upper end of the first fixing plate, and the second fixing plate is provided with four limiting holes matched with the limiting rods.

[0008] Preferably, notches are provided at both ends of the second fixing plate, and the two notches are matched with the threaded rods on both sides.

[0009] Preferably, a torsion spring is provided at the rotation connection between the two rotation rods and the inner wall of the groove on the same side.

[0010] Preferably, the ends of the two threaded rods are fixedly connected with fixing blocks, and the two fixing blocks are circular in design.

[0011] Preferably, a moving ring is slidably sleeved on each of the four limiting rods, and the lower ends of the four moving rings are elastically connected to the upper end of the first fixed plate via a spring.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By setting a locking mechanism, a movable ring and a spring, the limit rod is inserted into the limit hole, the lower end of the first fixed plate squeezes the movable ring to shrink the spring, and after the first clamping plate and the second clamping plate clamp the cable, the threaded rods on both sides are reset to the vertical direction and inserted into the notch, and cooperate with the spring and the movable ring. The lower end of the clamping ring is against the upper end of the second fixed plate to lock the first clamping plate and the second clamping plate. This locking method does not require the use of tools and the installation and disassembly process is convenient.

[0014] 2. By setting a limiting mechanism, during installation, multiple limiting rods are inserted into the limiting holes to achieve rapid limiting of the second fixing plate, thereby improving the locking accuracy and thus improving the installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0021] Reference Figure 1-4 A cable fixing clamp for a large-section cable tunnel includes a first fixing plate 1 and a second fixing plate 9. The upper end of the first fixing plate 1 is fixedly connected with a first clamping plate 8, and the lower end of the second fixing plate 9 is fixedly connected with a second clamping plate 12 that matches the first clamping plate 8. Notches 10 are provided at both ends of the second fixing plate 9. The two notches 10 are matched with the threaded rods 2 on both sides. The width of the notch 10 is greater than the diameter of the threaded rod 2, so that the threaded rod 2 can smoothly enter the notch 10, and the width of the notch 10 is smaller than the diameter of the clamping ring 3. The distance between the first clamping plate 8 and the second clamping plate 12 can be controlled by adjusting the position of the nut, so that cables of different quantities or sizes can be bundled.

[0022] In the utility model, the upper end of the first fixed plate 1 is provided with two locking mechanisms for locking the first clamping plate 8 and the second clamping plate 12, and the locking mechanism includes a mounting block 14 fixedly connected to the upper end of the first fixed plate 1, and a groove 17 is provided at the upper end of the mounting block 14, and a rotating rod 15 is rotatably connected between the inner walls at both ends of the groove 17, and a rotating block 13 is fixedly sleeved on the rotating rod 15, and a threaded rod 2 is fixedly connected to the end of the rotating block 13, and a nut is threadedly connected to the threaded rod 2, and the nut is rotatably connected to the end of the nut near the mounting block 14. There are clamping rings 3, and both clamping rings 3 are provided with anti-slip sleeves made of rubber, which can improve the anti-slip effect when pressed tightly to prevent loosening and falling off when clamped. The rotating connection between the two rotating rods 15 and the inner wall of the groove 17 on the same side is provided with a torsion spring 16, which can ensure the reset of the threaded rod 2. In the initial state, the threaded rod 2 is in a vertical state. The ends of the two threaded rods 2 are fixedly connected with fixed blocks 4, and the two fixed blocks 4 are both circular in design. The fixed blocks 4 can limit the movement of the nut to prevent the nut from moving away from the threaded rod 2.

[0023] In the utility model, a limiting mechanism for limiting the second fixed plate 9 is provided at the upper end of the first fixed plate 1, and the limiting mechanism includes four limiting rods 5 distributed in a rectangular shape and fixedly connected to the upper end of the first fixed plate 1, and four limiting holes 11 cooperating with the limiting rods 5 are opened on the second fixed plate 9, and movable rings 6 are slidably sleeved on the four limiting rods 5, and the lower ends of the four movable rings 6 are elastically connected to the upper end of the first fixed plate 1 by springs 7, and the movable rings 6 and the springs 7 can support the second fixed plate 9.

[0024] When the utility model is used, multiple limiting rods 5 are inserted into multiple limiting holes 11 to realize quick positioning of the second fixing plate 9, thereby improving the accuracy and convenience of installation. At this time, the lower end of the second fixing plate 9 squeezes the moving ring 6 to move it downward, and the spring 7 is squeezed and contracted. After bundling multiple cables, the threaded rods 2 on both sides are turned to the vertical direction, and the threaded rods 2 are inserted into the notches 10. The nuts are rotated to move on the threaded rods 2, driving the clamping ring 3 to move, and adjusting the clamping ring 3 to a suitable position. At this time, the spring 7 and the moving ring 6 cooperate with the clamping ring 3 to lock the second fixing plate 9, and no tools are needed, which is very convenient.

[0025] During disassembly, press the second fixed plate 9 downward to squeeze the movable ring 6 downward and squeeze the spring 7 to contract. At this time, the upper end of the second fixed plate 9 is separated from the lower end of the clamping ring 3. Rotate the threaded rods 2 on both sides so that the two threaded rods 2 leave the notch 10 to complete the disassembly.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
