Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of damping shock absorbers, in particular to a shock absorber damping control device. Background Art
[0002] Damping shock absorbers are important mechanical devices with widespread applications in numerous fields. They primarily utilize damping materials or specialized damping structures to dissipate vibration energy, thereby reducing vibration, lowering noise, and improving equipment stability. For example, in a car's suspension system, damping shock absorbers can cushion the impact of uneven road surfaces, making the driving experience more comfortable while protecting other vehicle components from excessive vibration. In industrial equipment, large motors and fans are prone to vibration during operation. Damping shock absorbers installed in their bases and other locations can effectively suppress vibration transmission, preventing equipment failures and shortened service life due to excessive vibration, thereby ensuring smooth and orderly production.
[0003] Existing dampers have a fixed damping rebound effect during use and cannot be adjusted later. When a damper with a different rebound effect is needed, the damper must be replaced, which is inconvenient. Regarding structural parameters such as the spring wire diameter, the number of effective coils, and the mid-diameter of the spring, the thicker the wire diameter, the fewer effective coils, and the smaller the mid-diameter, the "harder" the spring will be, and the rebound and tension will also change accordingly. This application addresses these spring characteristics and designs a damping shock absorber that can adjust the tension of the damping spring. Utility Model Content

[0027] The utility model provides a technical solution:
[0028] Example 1
[0029] Combine Figures 1 to 6 A shock absorber damping control device includes a damper body 3, an outer ring of the damper body 3 is sleeved with a damping spring 31, the upper and lower sides of the damper body 3 are fixedly connected with mounting heads 4, the outer ring of the mounting head 4 is provided with a connecting mechanism 1, and the outer side of the connecting mechanism 1 is provided with a locking mechanism 2.
[0030] The connecting mechanism 1 includes a rotating assembly 11 and a positioning assembly 12 . The rotating assembly 11 is arranged on the outer ring of the mounting head 4 , and the positioning assembly 12 is arranged on the outer ring of the rotating assembly 11 .
[0031] The rotating component 11 includes a cam 1101, which is fixedly connected to the outer ring of the mounting head 4. The outer ring of the cam 1101 is rotatably connected to a turntable 1102. The turntable 1102 is rotatably connected to the outer ring of the damper body 3. The turntable 1102 is fixedly connected to the upper and lower sides of the damping spring 31. The positioning component 12 includes a cam 1201, which is fixedly connected to the outer ring of the cam 1101. The bottom of the upper cam 1201 is fixedly connected to a fixing rod 1202.

The bottom of the fixing rod 1202 is fixedly connected to a slider 1204. The slider 1204 is slidably connected to the sleeve 1203.
[0032] Furthermore: the turntables 1102 on the upper and lower sides are rotatably connected to the outer ring of the cam 1101 and are fixedly connected to the upper and lower sides of the damping spring 31. When the damping device is in use, the staff can adjust the tension of the damping spring 31 by rotating the turntables 1102 on the upper and lower sides to adjust the rebound force of the damping spring 31, thereby achieving the control of the rebound effect when the damping device is in use, increasing the applicable scope of the damping device when in use, and making the operation simple and convenient for the staff to use. At the same time, the setting of the positioning component 12 positions the damper body 3 as a whole, so that the damper body 3 will not rotate during the telescopic operation, so that the damper body 3 will not reduce the conduction of force due to rotation, resulting in a reduction in the shock-absorbing effect, thereby increasing the stability of the damper body 3 when the damping structure is in use.
[0033] Example 2
[0034] See Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 and Figure 7 , and on the basis of Example 1, it is further obtained that the locking mechanism 2 includes a supporting component 21, an adjusting component 22 and a locking component 23, the supporting component 21 is arranged on the outside of the rotating component 11, the adjusting component 22 is arranged inside the supporting component 21, and the locking component 23 is arranged on the inside of the adjusting component 22.
[0035] The support assembly 21 includes a fixed arm 2101, which is fixedly connected to the outer ring of the mounting head 4. A fixed box 2102 is fixedly connected to the inner side of the fixed arm 2101, and the fixed box 2102 is arranged on the outer side of the turntable 1102. A reinforcing rod 1 2103 is fixedly connected to the inner side of the fixed arm 2101, and the reinforcing rod 1 2103 is fixedly connected to the outer ring of the convex plate 1101. A reinforcing rod 2104 is fixedly connected to the inner side of the fixed arm 2101, and the reinforcing rod 2104 is fixedly connected to the outer side of the convex plate 1101 and is located at the outer ring position of the mounting head 4. The adjustment assembly 22 includes a fixed cylinder 2201, which is fixedly connected to the outer side of the fixed box 2102, and the fixed cylinder The inner ring of 2201 is rotatably connected to the threaded shaft 2202, and the outer side of the threaded shaft 2202 is fixedly connected to the torsion disk 2203. The locking assembly 23 includes a rectangular barrel 2301, which is threadedly connected to the outer ring of the threaded shaft 2202, and the outer side of the rectangular barrel 2301 is fixedly connected to a slide 2302, which is sleeved on the outer ring of the threaded shaft 2202. The slide 2302 is slidably connected to the inner ring of the fixed box 2102, and the outer ring of the rectangular barrel 2301 is sleeved with a positioning sleeve 2303. The positioning sleeve 2303 is fixedly connected to the outer ring of the turntable 1102, and the rectangular barrel 2301 passes through the positioning sleeve 2303 and is clamped in the cam 1101.
[0036] Furthermore: the slide 2302 passes through the positioning sleeve 2303 and is engaged in the cam 1101 to complete the positioning of the cam 1101 and the turntable 1102, so that the turntables 1102 on the upper and lower sides are fixed to the cam 1101, thereby improving the stability of the device during use, so that the turntable 1102 will not rotate due to external force, ensuring that the tension of the damping spring 31 is maintained after adjustment, and at the same time, the staff only needs to rotate the torsion disk 2203 to control the rectangular screw barrel 2301 to move inward or outward, so that the staff can lock the rotating turntable 1102, and can also unlock the turntable 1102 and the cam 1101, so as to facilitate the subsequent control of the rotation of the turntable 1102 to adjust the tension of the damping spring 31. The operation is simple and convenient for the staff to use.
[0037] In actual operation, when this device is used, when it is necessary to adjust the rebound force of the damping spring 31, the staff first rotates the torsion disk 2203 on one side of the upper and lower sides, and the rotation of the torsion disk 2203 drives the threaded shaft 2202 to rotate, and the rotation of the threaded shaft 2202 drives the rectangular screw barrel 2301 on that side to move outward, and the rectangular screw barrel 2301 moves outward and retracts into the fixed box 2102 to release the connection with the convex plate 1101 and the turntable 1102, and then repeats the above operation until all the rectangular screw barrels 2301 on this side are retracted into the fixed box 2102, and then the staff uses a tool to insert the positioning sleeve 2303 to toggle the turntable 110 2 rotation. At this time, pay attention to the need. When it is necessary to increase the rebound tension of the damping spring 31, it is necessary to rotate the turntable 1102 to follow the direction of the damping spring 31. At this time, the damping spring 31 retracts inward and the inner diameter is reduced while the number of turns is increased. Conversely, the turntable 1102 is rotated in the opposite direction until the turntable 1102 is rotated to the appropriate position. At this time, the staff rotates the torsion disk 2203 to drive the rectangular barrel 2301 to move inward. At this time, the rectangular barrel 2301 moves inward through the positioning sleeve 2303 and is clamped inside the outer side of the convex plate 1101. At this time, the locking of the turntable 1102 is completed, and the adjustment of the tension and rebound force of the damping spring 31 is completed.
