Description

Technical Field

[0001] The utility model relates to the technical field of insulation clamps, in particular to a quick insulation clamp for communication cables. Background Art

[0002] The cable is manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups.

[0003] The cables need to be clamped during the installation process to guide the installation of the cables. Ordinary clamps, such as clamps, require tools or cable clamps when removing the cables later, such as the public (announcement) number CN203176545U. Similar cable clamps require multiple nuts to be rotated on the screw to adjust the inner diameter of the clamped area. The clamping time is long and the efficiency is low. Therefore, it is necessary to develop a communication cable quick insulation clamp. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation methods disclosed below.

[0031] Secondly, the utility model is described in detail with the schematic diagram. When describing the implementation mode of the utility model in detail, for the convenience of explanation, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the utility model. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included, and the rotation between components should be connected through bearing sleeves or bearing seats to reduce the friction between the two when rotating.

[0032] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] See also Figure 1-Figure 7 , shows a schematic diagram of the structure of a communication cable quick insulation clamp implementation method of the utility model, please refer to Figure 1-Figure 7 , a communication cable quick insulation clamp is introduced in detail.

[0034] A communication cable quick insulation clamp comprises a bottom plate 100, two ends of the bottom plate 100 are symmetrically rotated with rotating rods 110, the rod body of the rotating rod 110 is provided with side clamping plates 120, and the area surrounded by the bottom plate 100 and the two side clamping plates 120 is used to clamp the cable;

[0035] The front and rear side walls of the bottom plate 100 are provided with mounting frames 200 staggered up and down, and the side walls of the mounting frames 200 are rotatably provided with transverse linkage rods 210, and the rod bodies of the two linkage rods 210 on the same side of the front and rear are respectively provided with mutually meshing gears 220, and the front and rear ends of the rotating rod 110 are both provided with first worm gears 230, and the rod bodies of the linkage rods 210 are provided with first worm gears 240 meshing with the first worm gears 230 near the rotating rod 110;

[0036] A driving rod 300 is rotatably provided in the middle of the front and rear side walls of the bottom plate 100 , a second worm gear 310 is provided on the rod body of the linkage rod 210 located on the upper layer near the driving rod 300 , and a second worm 320 meshing with the second worm gear 310 is provided on the rod body of the driving rod 300 .

[0037] Furthermore, when the two side clamps 120 clamp the two sides of the cable, the upper ends of the two side clamps 120 do not touch. When in use, the device needs to clamp a cable of suitable diameter to avoid the side clamps 120 being unable to continue to rotate toward one side of the cable after the upper ends of the two side clamps 120 touch during use. It should be noted that in actual applications, the devices of different sizes can be produced. The devices are selected according to the diameter of the clamped cables, and when clamping the cables, the angle between the side clamps 120 and the bottom plate 100 is not greater than 60°.

[0038] Furthermore, insulating pads are provided on the top of the base plate 100 and on the side of the side clamping plate 120 close to the base plate 100, and the surface of the insulating pads is provided with anti-slip grooves, which improves the friction force when the base plate 100 and the two side clamping plates 120 clamp the cables, thereby improving the stability during installation.

[0039] Furthermore, the front and rear side walls of the base plate 100 are respectively provided with a hollow storage shell 330, and the inner cavity of the storage shell 330 is used to store the mounting frame 200, the linkage rod 210, the gear 220, the first worm gear 230, the first worm 240, the driving rod 300, the second worm gear 310 and the second worm 320, so as to avoid the components being directly exposed to the outside, thereby protecting the components.

[0040] Furthermore, the front end of the driving rod 300 extends and rotates to penetrate the front side wall of the storage shell 330, and a knob 340 is provided at the front end of the driving rod 300, so that the driving rod 300 can be driven to rotate from the outside through the knob 340.

[0041] Furthermore, a mounting plate 350 is provided on a side of the storage shell 330 away from the bottom plate 100 , and a mounting hole 360 ​​is opened on the mounting plate 350 , and the device can be conveniently installed at a desired position by screws adapted to the mounting hole 360 ​​.

[0042] Furthermore, the lead angle of the first worm 240 is smaller than the equivalent friction angle between the meshing teeth of the first worm wheel 230, so that the mechanism has self-locking properties and can achieve reverse self-locking, that is, only the first worm 240 can drive the first worm wheel 230, but the first worm wheel 230 cannot drive the first worm 240, so that when the two side clamps 120 clamp the cable, a stable angle will be maintained.

[0043] During specific use, the device is first installed in the desired position by means of screws adapted to the mounting holes 360, and the cable to be fixed is placed on the top of the base plate 100, with the two side clamps 120 located on both sides of the cable. The user then drives the drive rod 300 to rotate by means of the knob 340, and drives the upper linkage rod 210 to rotate by means of the second worm gear 310 and the second worm 320, and causes the lower linkage rod 210 to rotate in the opposite direction by means of the two meshing gears 220, and then drives the two rotating rods 110 to rotate in the opposite direction at the same time by means of the first worm 240 and the first worm gear 230, so that the two side clamps 120 rotate toward both sides of the cable at the same time, press the cable laterally, and achieve clamping of the cable. In addition, since the first worm gear 230 and the first worm 240 have self-locking properties, when the two side clamps 120 clamp the cable, they will maintain a stable angle, and the cable can be quickly removed without tools in the later stage.

[0044] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
