Description

Technical Field

[0001] The utility model relates to the technical field of spring shock absorbers, in particular to a spring shock absorber which is easy to install. Background Art

[0002] A spring shock absorber is a device that converts vibration mechanical energy into spring elastic potential energy. In the process of mutual conversion between mechanical energy and elastic potential energy, the friction between the connecting rods of the spring shock absorber generates chemical heat energy. After the heat energy is dissipated, the vibration is finally eliminated. However, the existing spring shock absorbers generally have the following technical problems in actual use scenarios:

[0003] It is relatively easy to assemble a mechanical device with a spring shock absorber directly from scratch. However, it is very inconvenient to add a spring shock absorber to a frame system that has been installed with a fixed distance. Because in the frame system with a fixed distance, in order to successfully dock with both ends of the spring shock absorber, the distance between the two ends must be adjusted. Either the distance between the frames must be reduced or expanded to fit the spring shock absorber, or the spring shock absorber must be stretched or compressed to fit the distance between the frame systems. Either way, it will cause inconvenience in the installation of the spring shock absorber.

[0004] Based on this, a spring shock absorber which is easy to install and can solve the above problems is proposed. Utility Model Content

[0023] Please combine Figure 1 As shown, the upper connecting rod mechanism includes two connecting plates 7 fixedly connected to the upper side of the limit sleeve 15, the two connecting plates 7 are distributed in a circular array, and the upper sides of the two connecting plates 7 are commonly fixedly connected with an upper connecting member 6. In this embodiment, the connecting member 6 is a double connecting plate structure with screw holes, which is suitable for fixing to a card-type connecting seat, and a nut abutment mechanism for positioning the threaded rod 3 is provided on one side of one of the connecting plates 7.

[0024] Please combine Figure 1 As shown, the nut abutment mechanism includes a positioning nut 8 threadedly sleeved with one of the connecting plates 7 , and the length of the positioning nut 8 is greater than the thickness of the connecting plate 7 .

[0025] Please combine Figure 2 As shown, the lower connecting rod mechanism includes four slots 12 opened on the inner wall of the limiting cylinder 2, and the four slots 12 are distributed in a circular array. The inside of the limiting cylinder 2 is provided with a movable slider mechanism sliding inside the slots 12.

[0026] Please combine Figure 2 and Figure 3As shown, the movable slider mechanism includes a slider 11 slidably connected to the inner side of the limiting cylinder 2. The slider 11 is a cylindrical structure. A plurality of blocks 13 are fixedly connected to the outer side of the slider 11. The plurality of blocks 13 are distributed in a circular array. Four blocks 13 are respectively paired with a plurality of slots 12. The blocks 13 are slidably connected to the inner side of the slots 12. A spring rod assembly that converts mechanical energy into spring elastic potential energy is provided on one side of the slider 11.

[0027] Please combine Figure 2 As shown, the spring rod assembly includes a connecting rod 9 fixedly connected to one side of the slider 11, a limiting hole 14 is provided at one end of the limiting cylinder 2, the limiting hole 14 is slidably connected to the connecting rod 9, a spring 10 is provided between the slider 11 and one end of the limiting cylinder 2 where the limiting hole 14 is provided, the spring 10 is sleeved in the outer space of the connecting rod 9, one end of the spring 10 is fixedly connected to one side of the slider 11, the other end of the spring 10 is fixedly connected to one side of the limiting cylinder 2 where the limiting hole 14 is provided, and one end of the connecting rod 9 is fixedly connected to the lower connecting member 1.

[0028] The implementation principle of a spring shock absorber that is easy to install in the embodiment of the present application is as follows: before docking with the anchors at both ends where the spring shock absorbers need to be installed, the staff first turns the handle 4 to adjust the position of the threaded sleeve 5 on the threaded rod 3 so that the lower connecting member 1 and the upper connecting member 6 can reach the two ends respectively, and then fix the lower connecting member 1 and the upper connecting member 6 to the anchors at both ends respectively through nuts. When the vibration source vibrates, the vibration is transmitted along the threaded rod 3, directly pushing the limit tube 2 to move. Regardless of whether the limit tube 2 moves upward or downward along the direction of the threaded rod 3, the slider 11 will move relatively along the slot 12, indirectly driving the spring 10 to deform, compress or elongate, thereby achieving the buffering effect of the spring 10.
