Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example:
[0025] Please see Figure 1 - Figure 4 The buffer device of a car shock absorber in this embodiment includes a telescopic rod 1, a telescopic cylinder 2 slidably disposed at the lower end of the telescopic rod 1, a connector 4 disposed at the lower end of the telescopic cylinder 2, and an auxiliary head 5 disposed at the upper end of the telescopic rod 1.
[0026] A limiting cylinder 6 and an auxiliary cylinder 7 are sleeved on the outside of the telescopic rod 1. The limiting cylinder 6 and the auxiliary cylinder 7 are symmetrically distributed. A spring 3 is provided between the limiting cylinder 6 and the auxiliary cylinder 7. The spring 3 is sleeved on the outside of the telescopic rod 1.
[0027] In this embodiment, by connecting and fixing the connector 4 and the auxiliary head 5 to the outer connecting component, and under the telescopic combination of the telescopic cylinder 2 and the telescopic rod 1, and the elastic action of the spring 3, the device has the effect of normal buffering. Since the specific connection settings are all existing technologies, they are not described in detail in this embodiment.
[0028] While the limiting cylinder 6 and the auxiliary cylinder 7 provide limiting effects for the spring 3 from the top and bottom sides respectively, they also provide restrictions on its sides, ensuring that the sides and both ends are simultaneously limited, thereby improving its overall strength and preventing the traditional protective support method from being too one-sided and affecting the stability of its side use.
[0029] The limiting cylinder 6 is fixedly sleeved on the lower half of the outer side of the telescopic rod 1, and several flow holes 601 are provided through the bottom of the inner wall of the limiting cylinder 6;
[0030] The auxiliary head 5 has an external thread 501 on its outer side, and the auxiliary cylinder 7 has a fastening cap 8 on its upper end. The inner wall of the fastening cap 8 has an internal thread, and the fastening cap 8 is threadedly connected to the external thread 501 through the internal thread.
[0031] By fixing the limiting cylinder 6 to the lower half of the outer side of the telescopic rod 1, the spring 3 is limited from the bottom. Based on the threaded connection of the external thread 501, the fastening cap 8 is positioned, and the position of the fastening cap 8 is easily adjusted, so that the fastening cap 8 has the effect of position adjustment, and the spring 3 is limited from the top, thereby ensuring the stability of the upper, lower and side restriction of the spring 3. Based on the distance between the limiting cylinder 6 and the auxiliary cylinder 7, the spring 3 can be prevented from being damaged due to overload.
[0032] With the flow support of the flow hole 601, it achieves the effect of air circulation and guides the water flow to prevent it from accumulating inside the limiting cylinder 6 and causing corrosion.
[0033] The auxiliary head 5 has several positioning holes 502 on its outer side. The positioning holes 502 are evenly distributed in a ring and are also evenly distributed vertically.
[0034] The fastening cap 8 has several auxiliary holes 801 through it. The auxiliary holes 801 are evenly distributed in a ring, and the auxiliary holes 801 are connected to the positioning holes 502 through the positioning mechanism 9.
[0035] The positioning mechanism 9 consists of a telescopic component 901, a fastening bolt 902, and an auxiliary bolt 903. The fastening bolt 902 is threadedly connected to the inner wall of the positioning hole 502, and the auxiliary bolt 903 is threadedly connected to the inner wall of the auxiliary hole 801.
[0036] The telescopic assembly 901 is rotatably connected to a rotating head 9021 and an auxiliary rotating head 9031 at opposite ends. The rotating head 9021 is rotatably mounted on the upper end of the fastening bolt 902, and the auxiliary rotating head 9031 is rotatably mounted on the upper end of the auxiliary bolt 903.
[0037] Under the positioning connection of the positioning mechanism 9, it is simultaneously inserted and positioned with the auxiliary hole 801 and the positioning hole 502 to ensure that the fastening cap 8 and the auxiliary head 5 are connected and fixed on the side, preventing the fastening cap 8 from loosening due to shaking, and improving the stability and reliability of its threaded connection.
[0038] Specifically, by rotating the screw in the middle of the telescopic component 901, the distance between the screws on both sides is adjusted, and the fastening bolt 902 is positioned and fastened to the positioning hole 502, and the auxiliary bolt 903 is positioned and fastened to the auxiliary hole 801. Based on the length adjustment effect of the telescopic component 901 itself, and the rotation of the rotating head 9021 and the fastening bolt 902, and the rotation of the auxiliary rotating head 9031 and the auxiliary bolt 903, the positioning angle and positioning distance of the fastening bolt 902 and the auxiliary bolt 903 are adjustable, so that the positioning mechanism 9 can provide a connection and fixation effect for the fastening cap 8 and the auxiliary head 5 from multiple directions, ensuring the stability of the positioning of the fastening cap 8.
[0039] The rotation of the rotating head 9021 and the fastening bolt 902, and the rotation of the auxiliary rotating head 9031 and the auxiliary bolt 903 are set to existing methods such as bearings, which are sufficient to achieve the desired rotation effect.
