Description

Technical Field

[0025] Example 1

[0026] Please refer to Figure 1-Figure 3 shown.

[0027] The present application provides an adjustable cable fastener, which mainly solves the problem that when the existing hangers use buckles and bolts to fix the cables, the cables are easily moved and the fixings are pulled by external factors. In the long run, the cables are easily damaged, and the equipment fixing the cables is also easily damaged; it is not convenient for later maintenance; the present structure installs the components such as the clamp 5, the mounting base 4, the locking assembly and the limit assembly for fixing the cables based on the fixed clamp 3, so as to ensure the stability of the present structure when in use; the set fixed clamp 3 is cylindrical, and its material is steel or aluminum profile among metals, and the mounting base 4 is installed on the end of the fixed clamp 3 by bolts or welding; a clamp 5 is provided on the mounting base 4 through a pin shaft, and a torsion spring (not shown in the figure) is sleeved on the pin shaft to abut against the mounting base 4 and the clamp 5. The free end of the clamp 5 extends outward after passing through the mounting base 4, and a locking component for locking the clamp 5 is provided on the mounting base 4. The above structure can select a suitable clamping force to clamp the cable according to the number and size of the cables, so as to avoid the problem that the outer layer of the cable is damaged due to excessive clamping force applied by the clamp 5 to the cable. A limiting component for preventing the cable from moving is provided in the space enclosed by the clamp 5 and the mounting base 4. The limiting component set after the cable is fixed by the above structure can move within a limited range with the fluctuating cable in the fixed area formed by the clamp 5 and the mounting base 4, so as to reduce the impact force of the cable on the clamp 5 and the mounting base 4, and avoid the problem that the clamp 5 fails in its clamping ability under the pulling of the cable.

[0028] In some technical solutions of the utility model, the clamp 5 and the mounting base 4 are both arc-shaped, and the inner arc surface of the clamp 5 is opposite to the inner arc surface of the mounting base 4. When the clamp 5 and the mounting base 4 are matched, the annular area formed can increase the clamping area of ​​the device, improve the clamping ability of the device for large-diameter cables, and the free end of the clamp 5 passes through the mounting base 4 and then extends outward to increase the movement space of the clamp 5, thereby increasing the adaptability of the device.

[0029] In some technical schemes of the utility model, a toothed belt 9 is provided on the side wall of the clamp 5 facing away from the mounting base 4, and a sliding sleeve 6 slidably connected to the clamp 5 is installed on the side wall of the mounting base 4; a mounting opening is opened on the outer wall of the sliding sleeve 6, and a lever 7 is rotatably provided in the mounting opening, and one end of the lever 7 placed in the sliding sleeve 6 is provided with a half tooth 14 engaged with the toothed belt 9; a locking component for locking the half tooth 14 is provided on the sliding sleeve 6. The toothed belt 9 is formed integrally with the outer arc surface of the clamp 5 by welding; the sliding sleeve 6 has a notch, which is connected to a slide groove adapted to the clamp 5 and opened on the mounting base 4, and the slide groove is opened along the circumference of the clamp 5; in this way, the movement space of the clamp 5 on the mounting base 4 can be guaranteed; the adaptability of the device is improved; the lever 7 and the half teeth 14 set on the lever 7 are rotatably set in the mounting opening, and the lever 7 can be rotated according to actual needs to adjust the position relationship of the clamp 5, and different clamping forces can be applied to different cables. After the half teeth 14 in the above structure are locked by the locking assembly, the clamp 5 is not easy to be displaced from the mounting base 4, thereby improving the fixing ability of the structure to the cable, and preventing the problem of failure of the clamping force of the fixing mechanism due to the movement of the cable.

[0030] In some technical solutions of the utility model, the locking assembly includes a locking rod 8, an internal threaded hole threadedly connected to the locking rod 8 is provided on the outer wall of the sliding sleeve 6, and a plurality of locking holes 15 adapted to the locking rod 8 are provided on the end surface of the half tooth 14. The lever 7 arranged in the sliding sleeve 6 is rotatably installed in the installation hole provided in the sliding sleeve 6 through a pin, and then the half tooth 14 is welded to the end of the lever 7 placed in the sliding sleeve 6; by rotating the lever 7 in this way, the toothed belt 9 arranged on the clamp 5 and the half tooth 14 can be meshed with each other, and the clamp 5 can be driven to move closer to the mounting base 4 on the mounting base 4, so as to clamp the cable; or the clamping effect can be released by moving away from each other; the locking rod 8 arranged in the internal threaded hole can be screwed into the internal threaded hole and partially embedded in the locking hole 15 by a wrench or other components, so as to fix the half tooth 14.

[0031] In some technical solutions of the utility model, the limiting assembly includes two limiting plates 11, and guide members 10 are installed on the side walls opposite to the clamp 5 and the mounting base 4, and the two limiting plates 11 are respectively connected to the two guide members 10. One of the limiting plates 11 is provided with two limiting blocks 13, and the other limiting plate 11 is provided with a guide groove adapted to the limiting blocks 13, so that the cable placed between the two limiting plates 11 can be prevented from sliding out due to external factors, which is not conducive to the above-mentioned components to protect the cables.

[0032] Furthermore, the guide 10 is a spring with good rigidity and flexibility. The guide 10 is fixedly connected to the limit plate 11, the clamp 5 and the mounting base 4 by buckles and bolts. With the above arrangement, in the initial state, when the cable is not swinging, the guide 10 is compressed in the vertical direction or horizontal direction (affected by the installation position). When the cable swings, the guide 10 can swing in multiple directions in space. The number of guides 10 connected to the same limit plate 11 is at least 2.

[0033] In some technical solutions of the present utility model, flexible plates 12 are provided on the opposite side walls of the limiting plate 11. The flexible plates 12 are rubber plates that can increase the friction between the limiting plate 11 and the cable, and can also protect the cable to avoid hard contact between the limiting plate 11 and the cable.

[0034] In some technical solutions of the utility model, a steering member is rotatably provided on the fixed base 3 , the steering member is connected to the mounting base 4 , and a self-locking member 2 which is self-locking with the mounting base 4 is provided on the steering member.

[0035] The self-locking member 2 is a sleeve, which is sleeved on the fixed card seat 3 and the steering member, and the self-locking member 2 is threadedly connected with the fixed card seat 3 and the steering member respectively. The steering member is a sleeve-shaped steel pipe body; the fixed card seat 3 is cylindrical, and the fixed card seat 3 is rotatably set in the steering body 1. The self-locking member 2 is threadedly connected with the fixed card seat 3 and the steering member to achieve the fixation of the two, and the steering body 1 is fixed to the object to be fixed by expansion screws or clamps. Through the above structure, this structure can provide installation and fixation in multiple directions when clamping and fixing cables.
