DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 4 An adjustable damper includes a damper body 1 and two pin heads 2. The inner walls of both ends of the damper body 1 are provided with annular grooves 6. An annular block 7 is welded to one side of the pin head 2, and the annular block 7 is slidably connected to the annular groove 6. A sliding column 9 is installed on one side of the annular block 7. The insides of both ends of the damper body 1 are provided with first sliding grooves 8, and the sliding column 9 is slidably connected to the first sliding grooves 8. Limiting plates 11 are installed on the top and bottom of the sliding column 9. A plurality of threaded grooves 16 are provided inside the limiting plates 11. The damper Two threaded holes 17 are provided at both ends of the body 1, and a screw 18 is connected to the inner thread of the threaded hole 17, and the screw 18 is plugged into the thread groove 16. The screw 18 is turned to move it out of the thread groove 16, and then the staff pulls the two pin heads 2 to both sides respectively to make the slide column 9 gradually move out of the first slide groove 8 until the damper is extended to the required length, and then reverses the screw 18 to insert it into the thread groove 16 at the corresponding position, so that the length of the damper can be adjusted and fixed, which is convenient for precise installation.

[0024] In the present utility model, it should be noted that the top and bottom of the damper body 1 are provided with limit grooves 10, and the limit plate 11 is slidably connected to the limit groove 10. Through the coordinated use of the limit plate 11 and the limit groove 10, the slide column 9 can stably move along the first slide groove 8, avoiding the slide column 9 from rotating during the movement, which makes the subsequent fixation time-consuming and labor-intensive. A circular hole 12 and a second slide groove 13 are provided inside the slide column 9, and a disc 15 is slidably connected in the second slide groove 13. A round rod 14 is fixed to one side of the disc 15 by bolts, and the round rod 14 passes through the circular hole 12 and is fixed to the inner wall of the damper body 1, and the circular hole 12 is connected to the second slide groove 13. The movement of the sliding column 9 changes the relative position of the disc 15 therein. The disc 15 can limit the distance that the sliding column 9 moves, so as to prevent the sliding column 9 from completely moving out of the first sliding groove 8 and affecting the use effect of the device. A pin seat 3 is provided on the outer side of the pin head 2, and a pin shaft 4 is installed between the pin seat 3 and the pin head 2, so as to facilitate the installation of the device on an external object. A connecting disk 5 is welded at the connection between the pin head 2 and the annular block 7, and the connecting disk 5 can limit the position of the damper body 1. A gasket 19 is sleeved on the outer side of the screw 18, and the gasket 19 is in contact with the outer wall of the damper body 1, and the gasket 19 can make the connection between the screw 18 and the damper body 1 tighter and more stable.

[0025] Working principle: When the damper needs to be extended, first turn the screw 18 to move it out of the threaded groove 16, then the staff pulls the two pin heads 2 to both sides respectively, so that the slide column 9 gradually moves out of the first slide groove 8, and the limit plate 11 moves along the limit groove 10 until the damper is extended to the required length, then reverse the screw 18 to insert it into the threaded groove 16 at the corresponding position, so that the length of the damper can be adjusted and fixed, which is convenient for the precise installation of the damper.
