[0002] A compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas. When the compressor is working, it will generate a lot of noise, which affects people around. Existing silencers for compressors generally use shock absorption to reduce noise.

[0003] Chinese patent document CN 217652879 U discloses a silencer for a compressor, which includes a box body, a shock absorbing structure is provided at the inner bottom end of the box body, a compressor is provided at the top of the shock absorbing structure, an air intake pipe is provided on the left side of the top of the compressor, an exhaust pipe is provided on the right side of the top of the compressor, and a silencer pipe is provided at the end of the exhaust pipe.

[0004] Although the above-mentioned document can silence the compressor by means of shock absorption, in actual use, when the shock absorption mechanism of the device encounters an unstable device, it is easy to cause the compressor to tilt, the shock absorption effect to deteriorate, and even cause damage to the compressor. To address the above problems, we propose a silencer for a compressor. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problem that the shock absorbing mechanism in the prior art is not stable enough and easily causes the compressor to tilt.

[0006] In order to solve the above technical problems, the utility model provides a compressor silencer

[0007] In one embodiment of the utility model, it includes a housing, and a shock absorbing mechanism for shock absorbing the compressor;

[0008] The bottom wall of the inner surface of the shell is provided with two grooves 1, and two sliders are slidably installed on the inner surfaces of the two grooves 1, a damper is fixedly installed on one side of the slider, a spring 1 is wound and installed on the outer surface of the damper, and a connecting rod 1 is hinged on the upper part of the slider; the upper ends of the four connecting rods 1 are hinged to a support plate;

[0009] A stabilizing mechanism is fixedly mounted on the bottom wall of the inner surface of the shell, an upper end of the stabilizing mechanism is fixedly mounted on the bottom surface of a support plate, a compressor assembly is arranged on the upper side of the support plate, and both sides of the support plate are slidably connected to a limiting mechanism.

[0010] In one embodiment of the utility model, the stabilizing mechanism includes a telescopic rod, which is fixedly mounted on the bottom wall of the inner surface of the shell, and the telescopic rod located at the lower part is provided with a sliding groove, and the inner surface of the sliding groove is slidably connected with a pipe sleeve, and the outer surface of the pipe sleeve is hinged with four connecting rods 2, and the upper ends of the four connecting rods 2 are hinged to the bottom wall of the support plate.

[0013] In an embodiment of the present utility model, the limit block is slidably mounted on the inner surface of the second groove.

[0014] In one embodiment of the utility model, the compressor assembly includes a guard plate, and grooves three are formed on both sides of the guard plate.

[0015] In one embodiment of the utility model, the limit block is slidably mounted on the third inner surface of the groove.

[0016] The above technical solution of the utility model has the following advantages compared with the prior art:

[0017] The utility model discloses a silencer device for a compressor, which first supports the compressor through a shock absorbing mechanism, reduces the vibration amplitude of the compressor when the compressor is working, and further reduces the contact area with other components of the device, and reduces noise by reducing the vibration amplitude of the compressor. During the movement of the device, the compressor can be prevented from being skewed by the telescopic rod in the stabilizing mechanism.

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1 to 6 As shown, a compressor silencer of the utility model comprises a housing 1 and a shock absorbing mechanism 2 for shock absorbing the compressor;

[0029] The bottom wall of the inner surface of the housing 1 is provided with two grooves 11, and two sliders 21 are slidably installed on the inner surfaces of the two grooves 11, a damper 23 is fixedly installed on one side of the slider 21, and a spring 22 is wound and installed on the outer surface of the damper 23, and a connecting rod 24 is hinged on the upper part of the slider 21; the upper ends of the four connecting rods 24 are hinged to the support plate 4;

[0030] A stabilizing mechanism 3 is fixedly mounted on the bottom wall of the inner surface of the shell 1, and the upper end of the stabilizing mechanism 3 is fixedly mounted on the bottom surface of a support plate 4. A compressor assembly 5 is arranged on the upper side of the support plate 4, and limiting mechanisms 6 are slidably connected to both sides of the support plate 4.

[0031] In order to achieve the purpose of shock absorption of the support plate 4 and the compressor fixed on the support plate 4, when the compressor applies pressure to the support plate 4, the support plate 4 will evenly distribute the pressure to the four connecting rods 24 at the lower end of the support plate 4. Since the bottom surface of the support plate 4 is hinged to the four connecting rods 24, the lower ends of the four connecting rods 24 are hinged with sliders 21, and the sliders 21 can slide on the inner surface of the groove 11. Therefore, when the support plate 4 provides downward pressure to the connecting rods 24, the connecting rods 24, the support plate 4 and the sliders 21 rotate, and the sliders 21 slide along the inner surface of the groove 11. A damper 23 and a spring 22 are connected to one side of the slider 21, which can slow down the sliding of the slider 21, thereby achieving the purpose of buffering and shock absorption of the compressor. By reducing the vibration generated by the compressor during operation, the generation and propagation of noise during operation can be effectively reduced.

[0032] During the transportation of the device, the compressor may have a tendency to move laterally, resulting in uneven force on the connecting rod 24 in the shock absorbing mechanism 2, so that the shock absorbing mechanism 2 is stuck or the compressor collides with the inner wall of the device. The stabilizing mechanism 3 can make the compressor and the support plate 4 move only vertically; the limiting mechanism 6 can make the compressor more convenient to install in the device and fix the compressor on the support plate 4.

[0033] Reference Figure 4 As shown, in one embodiment of the utility model, the stabilizing mechanism 3 includes a telescopic rod 31, and the telescopic rod 31 is fixedly mounted on the bottom wall of the inner surface of the shell 1. The telescopic rod 31 located at the lower part is provided with a slide groove 311, and the inner surface of the slide groove 311 is slidably connected with a pipe sleeve 32, and the outer surface of the pipe sleeve 32 is hinged with four connecting rods 2 33 around it, and the upper ends of the four connecting rods 2 33 are hinged to the bottom wall of the support plate 4.

[0034] In order to allow the support plate 4 to only be able to move vertically, the lower end of the telescopic rod 31 is connected to the bottom wall of the inner surface of the shell 1, and the upper end of the telescopic rod 31 is connected to the bottom wall of the support plate 4, and the upper ends of the four connecting rods 2 33 are hinged to the bottom wall of the support plate 4, and the lower ends of the four connecting rods 2 33 are hinged to the pipe sleeve 32, and the pipe sleeve 32 slides in the sliding groove 311 opened at the lower part of the telescopic rod 31. Since the four connecting rods 2 33 are all hinged to the pipe sleeve 32, the pipe sleeve 32 can only slide vertically along the telescopic rod 31, and the pipe sleeve 32 will move with the four connecting rods 2 33 at the same time, so the four connecting rods 2 33 can keep the support plate 4 stable when it moves vertically. When the support plate 4 tends to tilt, the connecting rod 2 33 cooperates with the pipe sleeve 32 to keep it stable without tilting.

[0035] The shock absorbing mechanism 2 will support the support plate 4 before the telescopic rod 31 , and the telescopic rod 31 has no force acting on the support plate 4 .

[0036] Reference Figure 5 to Figure 6As shown, in one embodiment of the utility model, grooves 41 are provided on both sides of the support plate 4, a limiting rod 61 is slidably installed on the inner surface of the groove 41, a spring 62 is wound and installed on the outer surface of the limiting rod 61, one end of the limiting rod 61 is fixedly connected to a limiting block 63, and the limiting block 63 is slidably installed on the inner surface of the groove 41, and the compressor assembly 5 includes a guard plate 51, grooves 52 are provided on both sides of the guard plate 51, and the limiting block 63 is slidably installed on the inner surface of the groove 52.

[0037] In order to fix the compressor, groove three 52 is opened on the guard plate 51 on both sides of the compressor. When installing the compressor, the groove three 52 is placed on the support plate 4 opposite to the limit block 63. During the placement process, the bottom plate of the compressor will first touch the inclined surface of the limit block 63. Under the action of pressure, the compressor squeezes the inclined surface of the limit block 63, which will drive the limit block 63 to move. During the movement of the limit block 63, the limit rod 61 will be pushed to slide. The limit rod 61 is slidably installed on both sides of the support plate 4. During the movement of the limit rod 61, the spring two 62 will be stretched. When the bottom wall of the compressor is placed on the support plate 4, the horizontal height of the bottom wall of the groove three 52 is lower than the bottom surface of the limit block 63. Under the action of the spring two 62, the limit block 63 will be bounced into the inside of the groove three 52, and the compressor will be fixed on the support plate 4, avoiding displacement of the compressor when it moves during work. The structure of the mechanism is simple, which is conducive to the rapid installation and disassembly of the compressor.

[0038] Working principle: First, place the groove three 52 vertically on the support plate 4 corresponding to the limit block 63. During the placement process, the compressor will first press the limit block 63 to keep it away from the compressor and stretch the spring two 62. When the horizontal height of the bottom wall of the groove three 52 on the compressor guard plate 51 is higher than the bottom surface of the limit block 63, the rebound force of the spring two 62 will push the limit rod 61 and then drive the limit block 63 to slide into the groove three 52, thereby fixing the compressor.

[0039] When the compressor is installed in the device for moving, the compressor and the support plate 4 may be skewed due to inertia and lateral traction. When the support plate 4 tends to tilt, the four connecting rods 2 33 on the bottom surface of the support plate 4 will jointly transfer the force generated by the tilt to the pipe sleeve 32. The pipe sleeve 32 will concentrate the force of the four connecting rods 2 33 and release it on the telescopic rod 31. Since the pipe sleeve 32 can only move vertically, the stabilizing mechanism 3 can keep the support plate 4 balanced, and then keep the compressor balanced without tilting.

[0040] When the compressor is working or the device is moved, the compressor and the support plate 4 apply pressure to the connecting rod 24. Due to the action of the stabilizing mechanism 3, the support plate 4 is pressed vertically downward, so the pressure can be evenly distributed on the four connecting rods 24. The four connecting rods 24 simultaneously disperse the force to the slider 21 connected at the lower end. The slider 21 slides in the groove 11 under the action of pressure. During the sliding process, the spring 22 and the damper 23 work together to slow down the sliding of the slider 21, thereby achieving the effect of shock absorbing the support plate 4 and the compressor.

[0041] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention of the utility model.
