DETAILED DESCRIPTION

[0023] 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.

[0024] Example 1: This example provides a JXD wedge-type parallel groove clamp that is easy to adjust. Figure 1-4 Specifically, it includes a groove shell 1, a long threaded nail 14, and an L-shaped plate 17. A rectangular block 11 is fixedly provided at the bottom of the groove shell 1. A slide groove 12 is opened in the rectangular block 11. A threaded hole 13 is opened at one end of the rectangular block 11. The long threaded nail 14 is threadedly connected with the threaded hole 13. A slider 15 is fixedly provided at the end of the long threaded nail 14. A limit plate 16 is fixedly provided on the long threaded nail 14. The long threaded nail 14 is rotatably connected to one end of the L-shaped plate 17. The other end of the L-shaped plate 17 is fixedly connected to a wedge block 18. First arc grooves 19 are provided on both sides of the wedge block 18. The groove shell 1 is C-shaped, and the groove shell 1 is normally open upward. Second arc grooves 111 are formed on the inner walls of both sides of the groove shell 1, and a plurality of anti-slip strips 112 are provided in the second arc grooves 111.

[0025] A pair of first arc grooves 19 are respectively located on the oblique sides of the wedge block 18, the long threaded nail 14 passes through the slide groove 12, the L-shaped plate 17 is located between the limit plate 16 and the head of the long threaded nail 14, the long threaded nail 14 passes through the L-shaped plate 17, the slider 15 is cylindrical, the slider 15 is in contact with the inner wall of the slide groove 12, the long threaded nail 14 passes through the limit plate 16, and the long threaded nail 14 passes through the slide groove 12.

[0026] In the specific implementation process, Figure 1 and Figure 2 As shown, firstly, the long threaded nail 14 is turned counterclockwise, and the long threaded nail 14 is rotated outward through the threaded hole 13 to extend, and the long threaded nail 14 drives the L-shaped plate 17 to move backward through the limit plate 16, and the L-shaped plate 17 drives the wedge block 18 to move backward until it moves to the rear end, and the limit block 21 supports the limit groove 22 so that it can no longer move backward, and the wire is passed through the gap between the parallel groove housing 1 and the wedge block 18, so that the wire is located between the first arc groove 19 and the second arc groove 111, and the long threaded nail 14 is turned clockwise. The long threaded nail 14 moves into the slide groove 12 through the threaded hole 13, and the long threaded nail 14 drives the wedge block 18 to move forward through the L-shaped plate 17, so that the gap between the first arc groove 19 and the second arc groove 111 becomes smaller and smaller until the wire is tightly clamped. Through the coordinated use of the long threaded nail 14, the L-shaped plate 17, the slide groove 12, the slider 15 and the limit plate 16, the entire wedge-shaped parallel groove wire clamp can be easily disassembled and can be used directly without assembly when in use.

[0027] Embodiment 2: In Embodiment 1, there is still the problem that the height of the air compressor bracket is fixed and cannot be adjusted. Therefore, based on Embodiment 1, this embodiment also includes:

[0028] A support bar 2 is fixed inside the parallel groove shell 1, and limit blocks 21 are fixed on both sides of the support bar 2. A limit groove 22 is provided at the bottom of the wedge block 18. The middle part of the limit groove 22 is T-shaped and the two ends are straight. The support bar 2 is fitted with the inner wall of the limit groove 22. The limit block 21 is located in the T-shape in the middle of the limit groove 22 and slides back and forth. The support bar 2 is located at the center of the parallel groove shell 1, and the limit block 21 is located in the middle and rear part of the support bar 2.

[0029] In the specific implementation process, Figure 3 and Figure 4 As shown, when the wedge block 18 moves forward and backward, the limit block 21 and the limit groove 22 can limit the movement to prevent displacement during the clamping process. The limit block 21 and the limit groove 22 can also make the wedge block 18 always move forward and backward on the support bar 2 without falling off, thus preventing the trouble of reassembly. Through the coordinated use of the support bar 2, the limit block 21 and the limit groove 22, the wire can be kept in the middle when being compressed, so that the clamping force on both sides is the same, and there will be no situation where one side is tight and the other side is loose.

[0030] Specifically, the working principle and operation method of the utility model are as follows:

[0031] Step 1: Prepare the wedge-shaped parallel groove wire clamp before use. Twist the long threaded nail 14 counterclockwise, and the long threaded nail 14 rotates outward through the threaded hole 13 to extend. The long threaded nail 14 drives the L-shaped plate 17 to move backward through the limit plate 16. The L-shaped plate 17 drives the wedge block 18 to move backward until it moves to the rear end, and the limit block 21 presses against the limit groove 22 so that it can no longer move backward.

[0032] Step 2: After the preparation work is completed, it can be brought to the site for installation. The wire is passed through the gap between the parallel groove housing 1 and the wedge block 18, so that the wire is located between the first arc groove 19 and the second arc groove 111. The long threaded nail 14 is turned clockwise, and the long threaded nail 14 moves into the slide groove 12 through the threaded hole 13. The long threaded nail 14 drives the wedge block 18 to move forward through the L-shaped plate 17, so that the gap between the first arc groove 19 and the second arc groove 111 becomes smaller and smaller, until the wire is tightly clamped;

[0033] 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.
