[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas and is the heart of a refrigeration system. It sucks in refrigerant gas at low temperature and low pressure from the suction pipe, compresses it by driving a piston through the operation of an electric motor, and then discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle. To ensure stability during use or turnover, the compressor is fixed on a compressor mounting bracket.

[0003] Most of the existing compressor mounting brackets directly fix the compressor through bolts, but their seismic resistance is insufficient. When the compressor works in a vibrating state for a long time, it will affect the service life of the compressor. In addition, the existing compressor mounting brackets are not convenient for the disassembly and assembly of the compressor, and the seismic resistance is not adjustable, unable to meet the usage requirements of users. Therefore, a compressor mounting bracket with high seismic resistance is proposed to solve such problems. Summary of the Invention

A second spring is fixedly connected between the column and the second piston.

[0008] The upper machine rod includes a rotating steel pipe, on which uniformly distributed meshing teeth are inserted. At the bottom of the compressor main body, equally spaced tooth grooves are provided, and the tops of the meshing teeth at the top are engaged with the tooth grooves. A limiting rod is threadedly connected to the inner side of the rotating steel pipe, and the end of the meshing tooth located inside the rotating steel pipe is in smooth contact with the limiting rod.

[0009] As a further description of the above technical solution:

[0010] The column is fixedly installed on the mounting frame by bolts. The second piston includes a piston slider, and a sliding plate is fixedly connected to the bottom of the piston slider. The sliding plate is slidably connected to the inside of the column. An air vent hole is provided on the sliding plate, and a baffle is hinged inside the sliding plate with resistance. One side of the baffle extends to the inside of the air vent hole, and the top of the baffle penetrates and extends to the bottom of the sliding plate.

The end of the limiting rod away from the threaded portion is arc-shaped.

[0014] The top of the second spring is fixedly connected to the inner top wall of the column, the bottom of the column is fixedly connected to the sliding plate, a fan-shaped cavity is provided inside the sliding plate, the baffle is hinged inside the fan-shaped cavity, and the inside of the fan-shaped cavity is communicated with the air vent hole.

[0015] As a further description of the above technical solution:

[0016] The first spring is always in a compressed state, the second spring is always in a stretched state, and a sealing ring is installed between the bottom of the column and the mounting frame.

[0017] As a further description of the above technical solution:

[0018] An airtight core is fixedly installed on the column, and the airtight core is communicated with the inside of the column.

[0019] As a further description of the above technical solution:

[0020] Two vertical plates are integrally formed on the top of the mounting frame.

When the compressor main body is vibrated, the downward pressure is transmitted to the first piston through the ejector rod, driving the first piston to slide downward inside the inner pipe, compressing the air inside the inner pipe. At the same time, with the elastic force of the first spring, the vibration is buffered and consumed. When the second piston moves further downward, the anti-tensile elastic force of the second spring is enabled, and the air inside the column is compressed, further playing a damping and buffering effect, improving the anti-vibration function of the mounting frame for supporting the compressor main body.

[0025] In this solution, when the piston slider moves downward under pressure, it will drive the slide plate to move downward synchronously, thereby compressing the air at the bottom of the slide plate and expanding the volume between the top of the slide plate and the column. The pressure difference is used to further buffer and reduce the impact force, playing an anti-vibration role. The air holes facilitate the air circulation between the top and bottom of the slide plate. When the downward speed of the slide plate is too fast and the air circulation volume cannot meet the balance of the pressure difference, it plays a damping role. By rotating the baffle, the hole size of the air hole can be adjusted to control the circulation volume size to meet the shock absorption requirements, further improving the anti-vibration function of the anti-vibration rod for supporting the compressor main body, and the practicability is stronger.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention;

[0038] Please refer to Figures 1 to 9 , in the present invention, a compressor mounting frame with high anti-seismic function includes a mounting frame 1 and a compressor main body 4. An anti-seismic rod 2 is connected to the mounting frame 1. The top of the anti-seismic rod 2 is rotatably connected to an upper machine rod 3, and the bottom of the compressor main body 4 is connected to the upper machine rod 3;

[0039] The anti-seismic rod 2 includes a column 21. An inner tube 24 is integrally formed inside the column 21. A jacking rod 22 is slidably connected inside the inner tube 24. The bottom end of the jacking rod 22 is fixedly connected to a first piston 23 that is slidably connected to the inner wall of the inner tube 24. A second piston 25 located at the bottom of the first piston 23 is slidably connected inside the inner tube 24. A first spring 26 is fixedly connected between the first piston 23 and the second piston 25. A second spring 27 is fixedly connected between the column 21 and the second piston 25;

[0040] The upper machine rod 3 includes a rotating steel pipe 31. Uniformly distributed meshing teeth 32 are inserted through the rotating steel pipe 31. Tooth grooves 41 arranged at equal distances are formed at the bottom of the compressor main body 4. The top of the meshing teeth 32 at the top is meshed with the tooth grooves 41. A limiting rod 33 is threadedly connected inside the rotating steel pipe 31, and the other end of the meshing teeth 32 contacts the limiting rod 33.

[0041] In the present invention, by rotating the stepped limiting rod 33 inside the rotating steel pipe 31, the supporting height of the limiting rod 33 for the top engaging teeth 32 is adjusted. The top engaging teeth 32 fall due to gravity and a part of the protruding part is recovered, thus acting as the teeth of a gear to engage with the tooth grooves 41 at the bottom of the compressor main body 4. Since the rotating steel pipe 31 is rotatably connected to the top rod 22, it is convenient for the user to push the compressor main body 4 onto the mounting frame 1, and with the anti-seismic rod 2 as a support, the limiting rod 33 is inserted into the inside of the rotating steel pipe 31, and the engaging teeth 32 are pushed out to fit against the inner wall of the tooth groove 41, thus changing the engagement to a clamping connection, restricting the rotation of the upper machine rod 3 and the movement of the compressor main body 4, and completing the fixation of the compressor main body 4. When the compressor main body 4 is vibrated, the downward pressure is transmitted to the first piston 23 through the top rod 22, driving the first piston 23 to slide downward inside the inner pipe 24, compressing the air inside the inner pipe 24. At the same time, with the elastic force of the first spring 26, the vibration is buffered and consumed. When the second piston 25 moves further downward, the anti-tensile elastic force of the second spring 27 is enabled, and the air inside the upright column 21 is compressed, further achieving a damping and buffering effect, improving the anti-seismic function of the mounting frame 1 for supporting the compressor main body 4.

[0042] Please refer to Figure 1 , 2 , 3 and 6, wherein: The upright column 21 is fixedly installed on the mounting frame 1 through bolts. The second piston 25 includes a piston slider 251. The bottom of the piston slider 251 is fixedly connected to a slide plate 254. The slide plate 254 is slidably connected to the inside of the upright column 21. Vent holes 252 are formed in the slide plate 254. A baffle 253 is hinged inside the slide plate 254 with resistance. One side of the baffle 253 extends to the inside of the vent hole 252. The top of the baffle 253 penetrates and extends to the bottom of the slide plate 254.

[0043] In the present invention, when the piston slider 251 is pressed and moves downward, it will drive the slide plate 254 to move downward synchronously, thus compressing the air at the bottom of the slide plate 254 and expanding the volume between the top of the slide plate 254 and the upright column 21. The impact force is further buffered and reduced by using the pressure difference, playing an anti-seismic role. The vent holes 252 facilitate the air circulation between the top and bottom of the slide plate 254. When the downward speed of the slide plate 254 is too fast and the air circulation volume cannot meet the balance of the pressure difference, it plays a damping role. By rotating the baffle 253, the hole size of the vent hole 252 can be adjusted to control the circulation volume size to meet the shock absorption requirements, further improving the anti-seismic function of the anti-seismic rod 2 for supporting the compressor main body 4, and the practicability is stronger.

[0044] Please refer to Figure 4 and Figure 5, wherein: uniformly distributed T-shaped grooves 34 are formed in the rotating steel pipe 31, the meshing teeth 32 are inserted into the inner sides of the T-shaped grooves 34, the limiting rod 33 is provided with a first stepped portion, a second stepped portion, a third stepped portion and a threaded portion, and one end of the limiting rod 33 away from the threaded portion is arc-shaped.

[0045] In the present invention, by screwing the limiting rod 33 into the inner side of the rotating steel pipe 31, the meshing teeth 32 are squeezed into the T-shaped grooves 34, and the detachment of the meshing teeth 32 from the rotating steel pipe 31 is avoided. The extrusion degree of the meshing teeth 32 can be adjusted by the provided first stepped portion, second stepped portion and third stepped portion, so as to facilitate the user to adjust and use.

[0046] Please refer to Figure 3 and Figure 6 , wherein: the top of the second spring 27 is fixedly connected to the inner top wall of the column 21, the bottom of the column 21 is fixedly connected to the sliding plate 254, a fan-shaped cavity 255 is formed inside the sliding plate 254, the baffle 253 is hinged inside the fan-shaped cavity 255, and the inside of the fan-shaped cavity 255 is communicated with the ventilation hole 252.

[0047] In the present invention, when the sliding plate 254 moves downward, the elastic force of the second spring 27 is used to buffer the pressure of the downward movement of the sliding plate 254, and at the same time provide power for the reset of the sliding plate 254. The fan-shaped cavity 255 is based on the moving space of the baffle 253, which facilitates the baffle 253 to block the ventilation hole 252 and control the through-hole size of the ventilation hole 252. When the column 21 is disassembled, the user can operate on the penetrating part of the baffle 253, which facilitates the user's use.

[0048] Please refer to Figure 3 , wherein: the first spring 26 is always in a compressed state, the second spring 27 is always in a stretched state, and a sealing ring is installed between the bottom of the column 21 and the mounting frame 1.

[0049] In the present invention, the compression of the first spring 26 and the stretching of the second spring 27 are used to buffer and store the downward impact force, so as to facilitate the reset of the shock-resistant rod 2, thereby playing a shock-resistant role for the compressor main body 4.

[0050] Please refer to Figures 1 to 3 , wherein: an airtight core 28 is fixedly installed on the column 21, and the airtight core 28 is communicated with the inside of the column 21.

[0051] In the present invention, through the airtight core 28, it is convenient for the user to supplement air into the inside of the column 21, so as to play a shock-resistant role by using the damping effect of air pressure, and avoid the influence of insufficient air inside the column 21 on the damping effect of the shock-resistant rod 2.

[0052] Please refer to Figure 1, wherein: Two vertical plates 11 are integrally formed on the top of the mounting frame 1. A resisting rod 12 is inserted through each of the two vertical plates 11. A third spring 13 is fixedly connected between the resisting rod 12 and the vertical plate 11. The opposite ends of the two resisting rods 12 are in contact with the compressor main body 4.

[0053] In the present invention, the vertical plates 11 on both sides of the mounting frame 1 can limit the movement range of the compressor main body 4. At the same time, through the elastic force of the third spring 13, the resisting rod 12 is extended to contact the compressor main body 4, further fixing and restricting the compressor main body 4, and at the same time playing an earthquake-resistant effect on the side of the compressor main body 4 to meet the earthquake-resistant requirements.

[0054] Please refer to Figure 1 , wherein: The resisting rod 12 is provided with an external thread, and the vertical plate 11 is provided with an internal thread matching the external thread.

[0055] In the present invention, by providing an external thread on the resisting rod 12 and an internal thread matching it, the resisting rod 12 can be rotationally fixed on the vertical plate 11, which is convenient for releasing the restriction on the compressor main body 4 when disassembling and assembling the compressor main body 4, so as to facilitate the user to disassemble and assemble the compressor main body 4 and improve work efficiency.

[0056] Working principle:

[0057] When installing the compressor main body 4: Rotate the restricting rod 33 inside the rotating steel pipe 31. When the first stepped portion of the stepped restricting rod 33 contacts the meshing teeth 32, the meshing teeth 32 at the top can be completely received inside the T-shaped groove 34 and the rotating steel pipe 31, keeping the outer surface of the rotating steel pipe 31 without protrusions, which is convenient for placing the compressor main body 4 on the outer surface of the rotating steel pipe 31 and adjusting the position of the tooth groove 41 at the bottom of the compressor main body 4 corresponding to the meshing teeth 32. Then screw in part of the restricting rod 33 so that its second stepped portion contacts the meshing teeth 32 at the top, and let the meshing teeth 32 at the top extend from the T-shaped groove 34 and mesh with the tooth groove 41 correspondingly, thereby positioning and restricting the compressor main body 4, which is convenient for the user to push the compressor main body 4 and keep the compressor main body 4 from shifting and misaligning during the pushing process;

[0058] When fixing the compressor main body 4: Fully screw the limiting rod 33 into the inner side of the rotating steel pipe 31, make the third stepped portion of the limiting rod 33 contact the meshing teeth 32, and completely push out the top of the meshing teeth 32 from the T-shaped groove 34, so that the top of the meshing teeth 32 is completely inserted into the inner side of the tooth groove 41 and fits against the inner wall of the tooth groove 41, filling the movement margin of the meshing drive, thereby restricting the movement of the compressor main body 4 on the rotating steel pipe 31. With the anti-seismic rod 2 as a support, insert the limiting rod 33 into the inner side of the rotating steel pipe 31, push out the meshing teeth 32 to fit against the inner wall of the tooth groove 41, thus changing the meshing to a clamping connection, restricting the rotation of the upper machine rod 3 and the movement of the compressor main body 4, and completing the fixation of the compressor main body 4. When the compressor main body 4 is vibrated, the downward pressure is transmitted to the first piston 23 through the ejector rod 22, driving the first piston 23 to slide downward inside the inner tube 24, compressing the air inside the inner tube 24. At the same time, with the elastic force of the first spring 26, the vibration is buffered and consumed. When the second piston 25 moves further downward, the anti-tensile elastic force of the second spring 27 is enabled, as well as the compression of the air inside the upright column 21, further achieving a damping and buffering effect. When the piston slider 251 is pressed and moves downward, it will drive the slide plate 254 to move downward synchronously, thereby compressing the air at the bottom of the slide plate 254 and expanding the volume between the top of the slide plate 254 and the upright column 21. Using the pressure difference to further buffer and reduce the impact force, playing an anti-seismic role. The air vent 252 facilitates the air circulation between the top and bottom of the slide plate 254. When the downward speed of the slide plate 254 is too fast and the air circulation volume cannot meet the balance of the pressure difference, it plays a damping role. By rotating the baffle 253, the hole size of the air vent 252 can be adjusted to control the circulation volume size to meet the shock absorption requirements, further improving the anti-seismic support effect of the anti-seismic rod 2 on the compressor main body 4, with stronger practicability, and improving the anti-seismic effect of the mounting frame 1 on the support of the compressor main body 4;

[0059] When disassembling the compressor main body 4: Unscrew a part of the limiting rod 33, make the second stepped portion of the limiting rod 33 contact the meshing teeth 32 at the top, change the connection relationship between the meshing teeth 32 and the tooth groove 41 from plug-in to meshing, so that the compressor main body 4 can move relative to the rotating steel pipe 31, facilitating the pushing of the compressor main body 4. When it is about to be detached, the limiting rod 33 can be unscrewed again to make the first stepped portion contact the meshing teeth 32, and the meshing teeth 32 can be retracted, so that the compressor main body 4 and the rotating steel pipe 31 lose the restriction, and thus the compressor main body 4 can be removed. Compared with the traditional manual handling for fine adjustment, it can more labor-saving and worry-free disassemble and assemble the compressor main body 4 on the mounting frame 1, improving the installation and use efficiency of the compressor main body 4, with novel structure and convenient operation to meet the usage requirements of users.

[0060] The above are only the preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
