[0024] Example 1

[0025] Please refer to Figure 1-Figure 4 shown.

[0026] The utility model provides a cable fastening device, which mainly solves the problem that the cable fixing parts in the prior art are complicated to operate and have poor fixing effect when fixing the cable. In order to solve the above problems, the fixed clamp body 7, the movable clamp body 5 and the transmission assembly are all installed on a fixed base in the device; the fixed clamp body 7 is fixedly arranged relative to the movable clamp body 5; the movable clamp body 5 is slidably arranged relative to the fixed clamp body 7 through the transmission assembly, and a locking assembly is provided in the transmission assembly to lock the movable clamp body 5 relative to the fixed clamp body 7. After such arrangement, the distance between the fixed clamp body 7 and the movable clamp body 5 can be controlled by the transmission assembly according to actual needs, so as to fasten the cable to the fixed object and ensure the stability of the cable when it is fixed. The locking assembly can prevent the transmission assembly from starting privately, causing the device to fail to fix the cable. The above structure can simplify the cable fixing method of the existing structure, providing convenience for operators to install cables.

[0027] The fixed frame body provided in the utility model is fixed to the upper part of the fixed base by bolts, and a U-shaped clamping area is provided on the fixed frame body. When the movable clamp body 5 is driven by the transmission assembly, the movable clamp body 5 is at a certain distance relative to the fixed clamp body 7; a part of the movable clamp body 5 will be placed in the clamping area of ​​the fixed frame body to prevent the cable from slipping from the gap between the fixed clamp body 7 and the movable clamp body 5 due to the influence of external factors when the cable is clamped by the fixed clamp body 7 and the movable clamp body 5.

[0028] Furthermore, two baffles formed integrally therewith are provided on the side walls opposite to the movable clamp body 5 and the fixed clamp body 7, which can further prevent the cable from sliding down between the two.

[0029] In some technical schemes of the present utility model, the specific structure of the transmission assembly includes a mounting frame 3, a moving gear 9 and a rack 4. The rack 4 is arranged on the mounting frame 3 along the movement direction of the moving clamp body 5. A guide groove 10 is opened on the side wall of the fixed base along the movement direction of the moving clamp body 5. A guide bar 2 connected to the rack 4 is arranged in the guide groove 10; the moving gear 9 is rotatably arranged on the fixed base and then meshes with the rack 4. The mounting frame 3 is L-shaped, and the two sections of the mounting frame 3 are perpendicular to each other; the movable clamp body 5 is fixed to one section of the mounting frame 3 by bolts; in fact, the guide groove 10 is slidably set on the fixed base along the vertical direction, and the cross-section of the guide groove 10 is wedge-shaped, so that the problem of separation between the two can be avoided when the mounting frame 3 moves on the fixed base; the movable gear 9 is rotatably set on the fixed base through a pin shaft; in this way, the operator can rotate the movable gear 9 clockwise through a tool, and at this time, the rack 4 meshing with the movable gear 9 will move upward in the vertical direction, and at this time, the movable clamp body 5 will approach the fixed clamp body 7, and then fix the cable; in the opposite operation, the movable clamp body 5 will move in the direction away from the fixed clamp body 7, and then release the cable.

[0030] Furthermore, the rack 4 is welded to the mounting frame 3 .

[0031] In some technical solutions of the present utility model, the locking assembly is installed on a fixed base to lock the movable gear 9.

[0032] In some technical schemes of the present utility model, the locking assembly includes a locking frame 8, a lever 12 and a locking plate 14 installed on a fixed base, and a plurality of locking teeth 15 are arranged around the outer circumferential wall of the locking plate 14; the lever 12 is rotatably arranged on the locking frame 8, and the lever 12 is connected to the locking plate 14; a limiting hole adapted for the locking plate 14 begins to be provided on the end face of the moving gear 9, and a plurality of internal teeth 16 engaged with the locking teeth 15 are provided on the inner wall of the limiting hole. Such a setting can increase the friction between the locking teeth 15 and the limiting hole, thereby improving the locking ability of the structure to the moving gear 9. The two ends of the locking frame 8 are fixed to the fixing holes on the fixed base by bolts, and then the lever 12 is inserted into the plug-in hole on the top of the locking frame 8. A guide strip 2 is provided on the outer wall of the lever 12 along the axial direction of the lever 12, and the guide strip 2 is fixedly connected to the outer wall of the lever 12 by welding; in this way, the lever 12 can only be plugged in and out along its axial direction and cannot make circular motion in the plug-in hole; in this way, the locking ability of the device to the moving gear 9 can be improved.

[0033] In some technical solutions of the utility model, a limit spring 13 is sleeved on the lever 12 and abuts against the locking frame 8. In order to prevent the lever 12 from sliding off the locking frame 8, at least the locking ability of the locking plate 14 to the moving gear 9 fails.

[0034] In some technical solutions of the present invention, a plurality of locking teeth 15 are obliquely arranged on the outer circumferential wall of the locking plate 14, and the reverse extension line of the locking teeth 15 is tangent to the circumference of the locking plate 14. Such an arrangement can increase the friction between the locking teeth 15 and the limiting holes, thereby improving the locking ability of the structure to the moving gear 9.

[0035] With such arrangement, the locking plate 14 and the locking tooth 15 fixed on the locking plate 14 do not need to be inserted or pulled out of the limiting hole by the lever 12, and the moving gear 9 can be driven by professional tools to drive the moving clamp 5. And with such arrangement, the locking plate 14 and the locking tooth 15 will always provide locking force for the moving gear 9.

[0036] In some technical solutions of the utility model, an insulator 6 is rotatably arranged in the clamping area of ​​the fixed clamp body 7. Such an arrangement can protect the cable and prevent the large current of the cable from being transmitted to the fixed object through the fixed clamp body 7, thereby achieving the purpose of insulation.

[0037] In some technical solutions of the utility model, the clamping surface of the movable clamp body 5 is concave in an arc shape in a direction away from the fixed clamp body 7, and a plurality of protective rollers 11 are rotatably provided on the clamping surface of the movable clamp body 5. The protective rollers 11 are also made of insulating materials. When the protective rollers 11 cooperate with the insulator 6, they can guide the subsequent transmission and winding of the cable when the device does not tighten the cable, thereby increasing the practicality of the device.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
