[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] like Figure 1 , Figure 2 A high-stability shock absorber shown comprises a base 1, a butterfly spring 3, a buffer layer 4 and an upper cover 5, wherein the butterfly spring 3 and the buffer layer 4 are respectively installed between the base 1 and the upper cover 5.
[0024] Specifically, if Figure 3 , Figure 4 As shown, the base 1 is a cylinder with a circular, rectangular, rounded rectangular or arc-edged rounded rectangular cross section. A mounting plate 11 is fixed on the right side of the base 1. Two mounting holes 111 are provided on the mounting plate 11. The base 1 is connected to the ground or the base of the equipment through the mounting holes 111. A cylindrical receiving groove 12 is provided at the center of the upper surface of the base 1, and a cylindrical lower positioning column 13 is fixed at the center of the bottom of the receiving groove 12. A sinking hole 15 is provided from bottom to top at the center of the lower surface of the base 1, and the sinking hole 15 passes through the upper surface of the lower positioning column 13. Among them, the inner diameter of the receiving groove 12 matches the outer edge diameter of the butterfly spring 3, and the outer diameter of the lower positioning column 13 matches the inner edge diameter of the butterfly spring 3.
[0025] like Figure 5 , Figure 6 As shown, the upper cover 5 is a shell with an opening at the bottom, and the shape of the inner wall of the upper cover 5 matches the shape of the side of the base 1. An upper positioning column 51 is fixed to the center of the inner top wall of the upper cover 5, and the outer diameter of the upper positioning column 51 matches the diameter of the inner edge of the butterfly spring 3. The upper positioning column 51 is connected to the top surface of the upper cover 5 through a frustum 52, thereby increasing the structural strength of the upper cover 5. An upper countersunk hole 53 is opened from top to bottom in the center of the upper cover 5, and the upper countersunk hole 53 passes through the upper and lower surfaces of the upper cover 5. The upper half of the upper countersunk hole 53 is provided with an upper internal thread 531, and the shock absorber is installed at the bottom of the device through the upper internal thread 531. The lower half of the upper countersunk hole 53 is provided with a lower internal thread 532, and the bolt is passed through the lower countersunk hole 15 and screwed with the lower internal thread 532 to achieve the connection between the upper cover 5 and the base 1.
[0026] like Figure 1-Figure 4As shown, the upper part of the side of the base 1 is indented to form a step 14, and the outer side of the step 14 is covered with an isolation layer 2, which is used to separate the base 1 from the upper cover 5 to avoid wear caused by direct friction between the base 1 and the upper cover 5, thereby extending the service life of the shock absorber. The isolation layer 2 can be made of nylon or polytetrafluoroethylene.
[0027] like Figure 1 , Figure 2 As shown, the outer edges of the two butterfly nuts 3 are connected to each other and sleeved between the upper cover 5 and the base 1, the inner edge of the butterfly nut 3 located on the upper side is sleeved on the outer side of the upper positioning column 51, and the inner edge of the butterfly nut 3 located on the lower side is sleeved on the outer side of the lower positioning column 13. The two butterfly springs 5 are interlocked and can withstand a large load with a small deformation, reducing the noise generated by the vibration of the equipment. At the same time, the butterfly springs 3 are limited in the horizontal direction by the upper positioning column 51, the lower positioning column 13 and the accommodating groove 12, which can prevent the spring from shaking and ensure the safe operation of the equipment.
[0028] like Figure 2 As shown, a buffer layer 4 is filled between the upper positioning column 51 and the lower positioning column 13. The buffer layer 4 is made of polyurethane. The setting of the buffer layer 4 can increase the damping coefficient of the shock absorber, increase the absorption of high frequencies, and improve the shock absorption effect at high frequencies.
[0029] like Figure 1-4 As shown, the lower surface of the base 1 is provided with a groove 16, and a shock-absorbing pad 6 made of rubber material is laid in the groove 16. The shock-absorbing pad 6 can play an auxiliary shock-absorbing role on the one hand, and can also cooperate with the isolation layer 2 to achieve the sealing between the upper cover 5 and the base 1 on the other hand, so as to avoid the influence of the external environment on the butterfly spring 3 and the buffer layer 4, and improve the weather resistance of the shock absorber.
