Description

Technical Field

[0001] The utility model relates to the field of spring dampers, in particular to a spring damper with an adjustable buffering function. Background Art

[0002] A spring damper, also known as a buffer or shock absorber, is a device used to control the movement of an object. It is mainly composed of springs, pistons, tube shells, fillers and other components, among which the spring is the core component, which absorbs energy and produces a damping effect through its deformation.

[0003] Existing spring dampers cannot automatically adjust the damping coefficient, which means that they have poor adaptability under different working conditions or load conditions. When the working conditions change (such as vibration frequency, amplitude or load increase), these spring dampers cannot provide the best buffering effect and lack flexibility.

[0004] Therefore, it is necessary to invent a spring damper with an adjustable buffering function to solve the above problems. Utility Model Content

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1-5 A spring damper with an adjustable buffering function is shown, comprising a base 1 for supporting the spring damper;

[0027] The telescopic sleeve 3 and the telescopic rod 6 are arranged above the base 1. The two side surfaces of the base 1 are provided with mounting grooves 2. The telescopic sleeve 3 and the telescopic rod 6 are provided with first springs 7 outside. The first springs 7 are used for buffering. A support plate 8 is provided above the telescopic rod 6. Connecting frames 9 are provided on both sides of the support plate 8.

[0028] The adjusting mechanism 10 is arranged inside the connecting frame 9 and is used to adjust the damping coefficient. The bolt head 1001 is driven to rotate by a tool. When the bolt head 1001 rotates, the screw rod 1002 is driven to rotate. Then, the screw rod 1002 is driven to rotate to drive the adjusting plate 1003 and the supporting plate 8 to squeeze the telescopic rod 6 and the first spring 7 outside the telescopic sleeve 3, thereby adjusting the damping coefficient.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the outer surface of the telescopic sleeve 3 is provided with an external thread 4, and the outer sleeve of the telescopic sleeve 3 is provided with a tightening ring 5. The tightening ring 5 on the outside of the telescopic sleeve 3 is rotated by a tool. When the tightening ring 5 rotates, the first spring 7 is squeezed. This method can also adjust the damping coefficient.

[0030] like Figure 1 , Figure 4 and Figure 5As shown, the adjustment mechanism 10 includes a bolt head 1001 and an adjustment plate 1003. The bolt head 1001 is arranged on one side above the connecting frame 9. A screw rod 1002 is fixedly installed below the bolt head 1001. The outside of the screw rod 1002 is movably connected with an adjustment plate 1003, which drives the bolt head 1001 to rotate and drives the screw rod 1002 below to rotate. The screw rod 1002 rotates the adjustment plate 1003 outside the screw rod 1002 and the support plate 8 on one side, thereby squeezing the first spring 7 to realize the adjustment buffer function.

[0031] like Figure 5 As shown, a slide bar 1004 is movably connected to one side of the inner side of the adjustment plate 1003, and the slide bar 1004 is fixed inside the connection frame 9. The slide bar 1004 is arranged so that the adjustment plate 1003 is more stable when moving.

[0032] like Figure 2 and Figure 4 As shown, the adjustment plate 1003 is fixedly connected to the support plate 8, the outer dimensions of the adjustment plate 1003 match the inner dimensions of the connecting frame 9, and the inner dimensions of the adjustment plate 1003 match the outer dimensions of the connecting frame 9, thereby improving stability during movement.

[0033] like Figure 1 and Figure 4 As shown, the connecting frame 9 is internally slidably connected to a support seat 11, and the support seat 11 is fixedly connected to the base 1. A second spring 12 is provided inside the connecting frame 9, and the second spring 12 is located between the support seat 11 and the support block 1005. Multiple groups of second springs 12 act as a buffer between the support seat 11 and the connecting frame 9.

[0034] The practical working principle of the present invention is as follows: first, the entire base 1 is installed at the required position, and then according to the damping coefficient of the required adjustment buffer, a tool is used to drive the bolt head 1001 to rotate. When the bolt head 1001 rotates, it drives the screw rod 1002 to rotate, and then the screw rod 1002 is rotated, thereby driving the adjustment plate 1003 and the support plate 8 to squeeze the telescopic rod 6 and the first spring 7 outside the telescopic sleeve 3, so as to adjust the buffer. At the same time, a wrench can also be used to rotate the tightening ring 5 outside the telescopic sleeve 3. When the tightening ring 5 rotates, the first spring 7 is squeezed. This method can also adjust the buffer. Finally, after the adjustment is completed, the equipment is installed on the support plate 8. In this way, the use process of the spring damper with adjustable buffer function is completed.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
