[0025] Example 1
[0026] See Figures 1 to 6 , an air-conditioning counterweight damping member, comprising an elastic member 1 and a counterweight member 2, the elastic member 1 having a first through hole 11 for connecting to a pipeline and a second through hole 12 for connecting to the counterweight member 2, the counterweight member 2 being inserted into the second through hole 12, and the elastic member 1 being sleeved on the pipeline where stress of the air-conditioning is concentrated. The number of counterweight members 2 can be one or more. In this embodiment, the number of counterweight members 2 is four, and the corresponding number of first through holes 11 is also four. The first through hole 11 of this embodiment is located at the center of the elastic member 1, while the second through holes 12 are evenly arranged in a circle around the periphery of the first through hole 11. The elastic member 1 can be made of a material with good elasticity, such as natural rubber, synthetic rubber, or soft PVC, and the material of the counterweight member 2 can be various metals, various alloys, or various metals and alloys with anti-corrosion treatment on the surface, or other materials such as cement.
[0027] The hardness of the elastic member 1 is 10-120 Shore A hardness, preferably 30 Shore A hardness, to achieve a better damping effect.
[0028] The first through hole 11 is a cylindrical through hole with an aperture A of 0-500 mm. The second through hole 12 is also a cylindrical through hole with an aperture F. The second through hole 12 can also be configured as another shape, such as a rectangular parallelepiped, and the shape of the corresponding counterweight 2 can also be adaptively adjusted to a rectangular parallelepiped.
[0029] The elastic member 1 of this embodiment is cylindrical, with an outer diameter of B, B>E+F, F is the aperture size of the second through hole 12, and the cross section of the elastic member 1 is as follows: Figure 2 As shown, E is the diameter of the circle formed by the line connecting the centers of the second through holes 12, and E>A+F.
[0030] The elastic member 1 of this embodiment is provided with a snap-in groove 13, which facilitates connecting the elastic member 13 to the pipeline where stress is concentrated. Figure 1 As shown, the size of the opening of the clamping slot 13 gradually increases from the inside to the outside, where the inside refers to the end adjacent to the first through hole 11 and the outside refers to the end away from the first through hole 11 .
[0031] The elastic member 1 of this embodiment has a fixing groove 14 on its periphery. The fixing groove 14 is used to bind the rolled strip to fix the elastic member 1 at the position of the fixing groove 14 to prevent the strap from falling off. Figure 3 As shown, the height of the fixing groove 14 is I, and the height of the elastic member 1 is G. In this embodiment, the fixing groove 14 is located in the middle of the elastic member 1. Therefore, G = 2*H + I, where H is the vertical distance from the upper or lower edge of the elastic member 1 to the edge of the fixing groove 14. The depth of the fixing groove 14 is J, where J < (BEF) / 2.
[0032] like Figure 4 As shown, the counterweight 2 of this embodiment is a cylindrical structure, but it can also be of other special-shaped structures. When a special-shaped structure is adopted, the second through hole 12 in the elastic member 1 needs to be changed to a special-shaped through hole of the same shape. The counterweight 2 can be a solid structure or a hollow structure, and a solid structure is preferred.
[0033] Figure 4 Where K represents the outer diameter of the counterweight 2. If the counterweight 2 is electroplated or painted, the K value represents the diameter including the electroplating layer and the paint layer. The counterweight 2 is preferably a galvanized steel column.
[0034] The height of the counterweight 2 is L. In this embodiment, L is greater than the height G of the elastic member 1. The upper and lower surfaces of the counterweight 2 extend beyond the upper and lower surfaces of the elastic member 1. Of course, the value of L can also be equal to or less than G. When the counterweight 2 is fixed, it can be completely located within the elastic member 1, or the upper and lower surfaces of the counterweight 2 can be flush with the upper and lower surfaces of the elastic member 1. Preferably, the height L of the counterweight 2 is the same as the height G of the elastic member.
[0035] In this embodiment, the end of the counterweight 2 is chamfered, which can be rounded or right-angled. The chamfer dimension M ranges from 0 to K / 2, where K is the diameter of the counterweight 2, preferably 0.5 to 3 mm.
[0036] The damping member of this embodiment was used in a test on the same air conditioner. First, the stress values of the intake pipe and exhaust pipe without the damping member of the embodiment were tested. The results are as follows: Figure 5 Then, a damping member of this embodiment was installed on the intake pipe and the exhaust pipe respectively, and the stress value was tested. The results are as follows: Figure 6 As shown, compared Figure 5 and Figure 6 It can be seen that after adding this damping component, the stress points greater than 12 MPa are significantly suppressed, and no shift of stress points or stress frequencies is caused.
[0037] Example 2
[0038] See Figure 7 The difference between the air conditioner counterweight damping member of this embodiment and the embodiment 1 is that: the elastic member 1 is provided with three third through holes 15, the number of which is four and is evenly arranged around the first through hole 11. The third through holes 15 are located between the second through hole 12 and the first through hole 11, and the aperture size of the third through holes 15 is N, where N is less than F. The third through holes 15 are used to reduce the damping value of the elastic member, and the number of the third through holes 15 can be one or more. Figure 7 As shown, O is the diameter of the circle formed by the line connecting the centers of the third through holes 15, and A+N<O<EF.
[0039] Example 3
[0040] See Figure 8 The difference between the air conditioner counterweight damping member of this embodiment and that of embodiment 1 is that the second through hole 12 and the third through hole 15 are holes with bosses at the ports, so the port diameter is smaller than the middle part diameter, the port diameter is greater than zero and less than N, and the height of the boss is greater than zero and less than G / 2.
[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
