DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0023] like Figures 1 to 4 As shown, a spring-type tensioning rigging for automobiles comprises a hook 1, a first buffer spring 2 sleeved on the outside of the hook 1 and a mounting shell 3 on the outside of the first buffer spring 2, a connecting structure 4 is installed below the mounting shell 3 by bolts, a plug-in assembly 5 is arranged below the connecting structure 4, and a steel cable 6 is plugged in the middle of the plug-in assembly 5;

[0024] The connecting structure 4 includes a connecting seat 401, and a mounting cavity 402 matching the mounting shell 3 is provided at the connection between the connecting seat 401 and the mounting shell 3. Two symmetrically arranged bearing plates 403 are fixedly installed below the connecting seat 401, and a mounting plate 404 is slidingly installed in the middle of the bearing plate 403. A sliding groove matching the mounting plate 404 is provided at the connection between the bearing plate 403 and the mounting plate 404, and the sliding groove is provided on the bearing plate 403. A fixing rod 405 is passed through the middle of the mounting plate 404, and one end of the fixing rod 405 is threadedly connected to the mounting seat 406, and the plug-in component 5 is arranged inside the mounting seat 406. Embodiment 2

[0025] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0026] One end of the fixing rod 405 away from the mounting seat 406 is rotatably mounted on the bottom end surface of the connecting seat 401 through a bearing, and a thread is arranged on the outer side of the fixing rod 405. The mounting plate 404 and the fixing rod 405 are threadedly connected. A second buffer spring 7 is sleeved on the outer side of the fixing rod 405. One end of the second buffer spring 7 is fixedly mounted on the bottom end surface of the connecting seat 401, and the other end is fixedly mounted on the mounting plate 404. The threaded connection between the fixing rod 405 and the mounting plate 404 can realize the rotation of the fixing rod 405. When the fixing rod 405 is rotated, the mounting plate 404 will slide inside the slide groove and squeeze the second buffer spring 7. After the rotation is completed, a locking hoop can be sleeved on the outer side of the fixing rod 405 to fix the fixing rod 405. In this way, by squeezing the second buffer spring 7, the spring pressure of the spring-type tightening rigging during use can be adjusted.

[0027] The plug-in assembly 5 includes a pull plate 501, and both ends of the inner side of the pull plate 501 are fixedly installed with an insertion rod 502. The outer side of the insertion rod 502 is sleeved with a compression spring 503. One end of the compression spring 503 is fixedly installed on the inner side of the pull plate 501, and the other end is fixedly installed inside the mounting seat 406. The plug-in assembly 5 can be connected by pulling the pull plate 501, and pulling the insertion rod 502 and the compression spring 503 through the pull plate 501, and then the insertion rod 502 can be used to plug and fix the steel cable 6.

[0028] A fixing groove 8 matching the insertion rod 502 is provided at the connection between the steel cable 6 and the insertion rod 502, and the fixing groove 8 is provided on the steel cable 6. One end of the insertion rod 502 passes through the steel cable 6, and one end of the insertion rod 502 extends to the other end of the mounting seat 406. The fixing groove 8 can facilitate the insertion and fixation of the steel cable 6 by the insertion rod 502, thereby achieving the insertion and fixation effect of the steel cable 6.

[0029] Working principle: First, the mounting shell 3 is fixed on the connecting seat 401 by bolts, and then one end of the steel cable 6 is inserted into the interior of the mounting seat 406. Before insertion, the pull plate 501 is pulled so that the pull plate 501 drives the insertion rod 502 and the compression spring 503 on the outside of the insertion rod 502 to separate from the interior of the mounting seat 406. When the steel cable 6 is inserted into the interior of the mounting seat 406, the pull plate 501 is released so that the compression spring 503 rebounds back to the insertion rod 502, and the insertion rod 502 passes through the fixing groove 8 of the steel cable 6, and at this time, the insertion rod 502 will extend to the other side of the mounting seat 406. The steel cable 6 is fixed to achieve a detachable installation effect of the steel cable 6, and then the other end of the steel cable 6 is installed inside another set of mounting seats 406. During use, the fixing rod 405 is rotated, and when the fixing rod 405 is rotated, the mounting plate 404 will slide inside the slide groove and squeeze the second buffer spring 7. After the rotation is completed, a locking hoop can be sleeved on the outside of the fixing rod 405 to fix the fixing rod 405. In this way, by squeezing the second buffer spring 7, the spring pressure of the spring-type tightening rigging during use can be adjusted.
