DETAILED DESCRIPTION
[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0029] Reference Figure 1-3 A parallel groove wire clamp includes a base 1, two groups of clamping blocks 2 slidably installed on the top of the base 1, an arc-shaped cover plate 3 slidably installed between the clamping blocks 2, and a fastening rod 4 passing through the base 1 and the arc-shaped cover plate 3. Two groups of pressing blocks 32 are fixedly installed at the bottom of the arc-shaped cover plate 3. The two sides of the pressing blocks 32 and the clamping blocks 2 are slidably installed through inclined sliders 33 and inclined sliding grooves 22.
[0030] Reference Figure 5-6 , a sliding layer 13 is installed on the base 1, two groups of plane sliding grooves 16 are opened on the top of the sliding layer 13, and a plane slider 23 is fixedly installed on the bottom of the clamping block 2, and the plane slider 23 and the plane sliding groove 16 slide in cooperation with each other. Through the cooperation and sliding of the plane slider 23 and the plane sliding groove 16, it is convenient for the clamping block 2 to open and close and adjust the position, and clamp or unfold the cable. Two groups of wire grooves 11 are opened on the base 1, and a bearing block 12 is fixedly installed on the top of the wire groove 11 on the base 1, and a closing plate 21 that cooperates with the bearing block 12 is fixedly installed on one side of the clamping block 2. The wire groove 11 is closed by the closing plate 21 and the bearing block 12, and the cable is closed and clamped. A threaded through-hole 31 is opened on the arc cover plate 3, and the inclined sliding groove 22 is opened and installed on the side of the clamping block 2. Through the setting of the threaded through-hole 31, it is convenient for the fastening rod 4 to limit and fix the base 1 and the arc cover plate 3.
[0031] Reference Figure 4 , the top and bottom of the fastening rod 4 are both installed with threaded parts 41, and nuts 42 are threadedly installed on the threaded parts 41. The top and bottom of the fastening rod 4 are limited and fixed by the nuts 42. Two groups of through holes 14 are opened on the base 1, and a hexagonal limiting groove 15 is opened at the bottom of the base 1 at the position of the through holes 14. The nut 42 at the bottom is limited by the hexagonal limiting groove 15 to prevent the nut 42 from loosening. The arc-shaped cover plate 3 is pressed down to make the clamping block 2 slide to both sides, thereby forming a closed state with the base 1 to clamp and position the cable, and the closing plate 21 and the bearing block 12 cooperate to close the wire groove 11, and the cable is closed and clamped, without causing extrusion and clamping to the cable itself, reducing the deformation of the cable, thereby avoiding excessive extrusion affecting its use.
[0032] Working principle: First, disassemble the fastening rod 4, slide the arc cover plate 3, make the lower pressing block 32 slide out from between the clamping blocks 2, slide one set of clamping blocks 2 to one side, place the cable from the top position of the wire trough 11 into the wire trough 11, operate the clamping block 2 on the other side in the same way, and prevent the cable from entering the wire trough 11, then slide the lower pressing block 32 between the clamping blocks 2, and as the lower pressing block 32 slides down, the two sets of clamping blocks 2 slide to both ends, so that the clamping block 2 and the base 1 are in a closed state. The fastening rod 4 is passed through the base 1 and the arc-shaped cover plate 3, and the bottom of the fastening rod 4 is threadedly installed by the nut 42. After the installation is completed, the fastening rod 4 is pulled up to make the nut 42 fit into the hexagonal limit groove 15 and fixed. Finally, the top nut 42 is threadedly fixed on the top of the fastening rod 4 to increase the fastening between the arc-shaped cover plate 3 and the base 1. At the same time, the tighter the nut 42 is fixed, the stronger the extrusion effect between the clamping block 2 and the base 1 is, thereby ensuring the clamping effect of the cable.
