[0030] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the utility model.

[0031] As shown in Figures 1-4 The utility model provides a polygonal rubber damper for fan, including rubber spare body 1;

[0032] The rubber spare body 1 is in polygonal cone structure, is equipped with two internal thread bushings 2 in the through hole in the middle part and its longitudinal interval;

[0033] First bolt 3 is arranged at the small head top end of rubber spare body 1, and it is connected internal thread bushing 2 into rubber spare body 1;

[0034] Second bolt 4 is arranged at the big head bottom end of rubber spare body 1, and it is connected another internal thread bushing 2 into rubber spare body 1;

[0035] The working principle and beneficial effects of the above-mentioned embodiments are as follows:

[0036] The utility model fan will produce vibration and impact force in the running process, and the damper absorbs the vibration of the fan through the elastic deformation of the polygonal rubber spare body 1, reduces the vibration amplitude of the fan, thereby protecting the fan equipment and the surrounding structure;

[0037] The mounting mode of the above-mentioned damper is that the first bolt 3 is screwed through the fan and an internal thread bushing 2 in the rubber spare body 1, and the second bolt 4 is screwed through the fan mounting seat and another internal thread bushing 2 in the rubber spare body 1, which can ensure the good connection between the damper and the fan;

[0038] The vibration and impact force generated by the utility model fan during operation are absorbed by the elastic deformation of the rubber spare body 1, and the high elasticity and viscoelastic properties of the rubber material can effectively reduce the vibration amplitude; the polygonal cone structure of the rubber spare body 1 provides good stability, so that it can remain stable when bearing pressure and reduce displacement caused by vibration; the first bolt 3 and the second bolt 4 are connected with the internal thread bushing 2 in the rubber spare body 1 respectively, which ensures the firm connection between the damper and the fan, transmits the necessary force between the fan and the damper, and allows the rubber spare body 1 to deform within a certain range to absorb vibration.

[0039] In one embodiment,

[0040] A plurality of sets of concentric rubber rings 5 are provided at the bottom end of the rubber part body 1 and protrude outward from the bottom end surface of the rubber part body 1. The rubber rings 5 are designed as an integral structure with the rubber part body 1 or are combined by adhesion. The structure of the rubber rings 5 reduces the contact surface with the fan mounting seat. Since the rubber material may creep under long-term pressure, it may adhere to the contact surface, thereby reducing the adhesion problem caused by the large contact surface and facilitating subsequent maintenance and replacement work.

[0041] In one embodiment,

[0042] The first round corner is provided at the polygonal peripheral sharp corner of the rubber part body 1, and the second round corner is provided at the intersection between the top end and the periphery. The first round corner is smaller than the second round corner.

[0043] Through the rounding treatment, stress can be dispersed, and material fatigue and crack caused by stress concentration can be reduced.

[0044] In one embodiment,

[0045] The rubber part body 1 is a hexagonal cone. Compared with other polygonal structures (such as quadrilateral or pentagonal), the hexagonal structure is more stable in geometry. The hexagonal structure provides more support points and symmetry, which helps the rubber part body 1 to maintain the stability of the shock absorber when bearing pressure.

[0046] In one embodiment,

[0047] A spacer 6 and a spring washer 7 are connected to the contact end of the first bolt 3 and the rubber part body 1. The spacer 6 contacts the rubber part body 1, and the diameter of the spacer 6 is greater than the top end surface of the rubber part body 1. The spring washer 7 maintains the pre-tightening force of the first bolt 3, prevents the bolt from loosening due to vibration, and ensures that the connection between the shock absorber and the fan is always firm. The spacer 6 can completely cover the top end surface of the rubber part body 1, providing more uniform pressure distribution.

[0048] In one embodiment,

[0049] The first bolt 3 and the second bolt 4 are hexagonal head bolts, which are convenient for quick installation using common hand tools.

[0050] In one embodiment,

[0051] The taper of the rubber part body 1 is 5°. A 5° taper means that the rubber part body 1 gradually increases from the top end to the bottom. This gradual contact can more evenly distribute pressure and reduce local stress concentration.

[0052] In summary,

[0053] The utility model discloses a polygon rubber shock absorber for fan, the vibration and impact force produced when fan is running are absorbed through the elastic deformation of the rubber part body, and the high elasticity and viscoelasticity characteristics of the rubber material can effectively reduce the vibration amplitude.

[0054] The polygon cone structure of the rubber part body provides good stability, so that it can keep stable when bearing pressure and reduce displacement caused by vibration.

[0055] The first bolt and the second bolt are connected with the internal thread bushing in the rubber part body respectively, so as to ensure the firm connection between the shock absorber and the fan, transfer the necessary force between the fan and the shock absorber, and allow the rubber part body to deform within a certain range to absorb vibration.
