Description

Technical Field

[0001] The invention relates to the field of compressors, and in particular to a shock-absorbing support foot for a compressor and a compressor. Background Art

[0002] The compressor is a fluid machine that elevates low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. It inhales low-temperature, low-pressure refrigerant gas from the suction pipe, compresses it through the operation of the motor to drive the piston, and then discharges high-temperature, high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. The compressor vibrates when working and causes noise at the same time. In order to reduce this noise, a mounting plate is provided at the bottom of the compressor casing, and fixing bolts are welded on the mounting plate. The central through hole of the compressor vibration damping pad is inserted into the fixing bolts on the mounting plate, thereby flexibly connecting the compressor to the bottom plate of the air conditioner. When the compressor is running, the vibration damping pad can absorb the vibration of the compressor and reduce the outdoor noise of the air conditioner.

[0003] In order to ensure reliable welding of the compressor legs, the legs are usually moved from the bottom of the cylinder to the outer wall of the cylinder. The advantage is that the center of gravity of the compressor is lowered. The disadvantage is that different types of legs are required for different cylinder wall thicknesses. The thickness specifications are usually 2.8, 3.0, 3.2, and 3.5. Different legs have only slight differences in the distance between the center hole and the back plate, which can easily cause material mixing during mass production. Summary of the invention

[0004] The object of the present invention is to provide a shock-absorbing support foot for a compressor and a compressor to solve the above-mentioned problem.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A shock-absorbing support foot for a compressor, comprising an L support foot and a shock-absorbing pad, wherein the shock-absorbing pad is installed on the L support foot; One end of the L support leg is welded to the bottom end of the compressor, and the other end of the L support leg is provided with double eyelets. The vibration damping pad is provided with a connecting portion, and the connecting portion is inserted into the double eyelets of the L support leg.

[0006] Furthermore, the L-leg includes a back plate and a bottom plate, the back plate is connected to the bottom of the compressor outer wall by projection welding, and two eyelets are arranged on the bottom plate.

[0007] Furthermore, the vibration-damping pad includes a vibration-damping body, a boss and a through hole; the center of the vibration-damping body is provided with a through hole, and the periphery is provided with a plurality of bosses.

[0008] Furthermore, the top of the shock-absorbing body is a first boss and a second boss from top to bottom, and the connecting part is arranged between the first boss and the second boss; the upper surface of the second boss is a second boss plane, and when the connecting part is inserted into the double eyelets of the L-leg, the bottom plate is placed on the second boss plane.

[0009] Furthermore, the outer diameter of the connecting portion is a binocular structure.

[0010] Furthermore, the distance between the two center points of the double eyelets is a, 0.2≤a≤0.7; the center line of the double eyelets passes through the center of the compressor, and a marking line is set on the center line close to the center of one side.

[0011] Furthermore, the centers of the two eyes on the side of the connecting portion provided with the marking line coincide with the axis of the central through hole.

[0012] Furthermore, the distance between the centers of the double-eye structures of the outer diameter of the connecting part is b, b=a; a triangular mark is set in the direction of the line connecting the centers of the double-eye structures; when the vibration damping pad is assembled with the L-leg, when the wall thickness of the cylinder is thicker, the triangular mark is installed along the L-leg marking line away from the compressor body; when the wall thickness of the cylinder is thinner, the triangular mark is installed along the L-leg marking line close to the compressor body.

[0013] Furthermore, the back plate is arc-shaped, and the radius of the arc is R, and the radius of the outer peripheral wall of the compressor cylinder is r, satisfying r+0.5≤R≤r+2.

[0014] A compressor comprises the shock-absorbing support foot for the compressor.

[0015] Compared with the prior art, the present invention has the following technical effects: The invention has two components with double-eye structures, and can meet the connection requirements of compressors with different barrel wall thicknesses and air conditioner bottom plates through different installation directions. The specifications of the L-legs are greatly reduced. The invention realizes the effective connection of compressors with different barrel wall thicknesses and air conditioner bottom plates, and significantly reduces the specification requirements of the L-legs.

[0016] By providing double eye holes on the L-shaped support legs and a connection part on the vibration-damping pad that can be inserted into the double eye holes, the vibration-damping pad can be installed in an adjustable direction as needed. This design enables the same set of vibration-damping support legs to adapt to compressors with different cylinder wall thicknesses, without the need to design different support legs for each wall thickness, greatly improving the adaptability and flexibility of the product.

[0017] Since the shock-absorbing feet can be applied to compressors with various cylinder wall thicknesses, the number of L-foot specifications is greatly reduced. This not only simplifies production and inventory management, but also reduces manufacturing and procurement costs, which is particularly beneficial for large-scale production.

[0018] The design of the vibration-damping pad, especially the bosses and through-holes on it, helps absorb and disperse the vibration generated by the compressor during operation, thereby improving the stability and durability of the entire system. The double-eye structure connection further enhances this vibration-damping effect because it allows for more precise adjustment of the position and angle of the vibration-damping pad to achieve the best vibration-damping effect.

[0019] The double eye holes on the L-leg and the connection part on the vibration-damping pad are designed with marking lines or triangular marks, which provide clear guidance for installation. During the installation process, you only need to select the appropriate installation direction according to the cylinder wall thickness of the compressor and align the marks, which greatly simplifies the installation process and improves installation efficiency and accuracy.

[0020] In summary, this technical solution, through innovative design and clever assembly methods, achieves wide adaptability of the shock-absorbing feet to compressors with different cylinder wall thicknesses, while improving the shock-absorbing effect, installation efficiency, reliability and safety, and optimizing space utilization. These technical effects together constitute the core value of this technical solution, bringing significant benefits to manufacturers and users of compressors and air conditioners.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Example 1, please refer to Figure 1 The present invention provides a shock-absorbing support foot for a compressor, comprising an L support foot 1 and a shock-absorbing pad 2, wherein the shock-absorbing pad 2 is installed on the L support foot 1; One end of the L support leg 1 is welded to the bottom of the compressor, and the other end of the L support leg 1 is provided with double eyelets 121. The vibration damping pad 2 is provided with a connecting portion 231, which is inserted into the double eyelets 121 of the L support leg.

[0026] The purpose of the present invention is to provide a shock-absorbing support foot for a compressor, both parts of which have a double-eye structure, and can meet the connection between compressors with different cylinder wall thicknesses and air conditioner bottom plates through different installation directions, greatly reducing the specifications of the L support foot.

[0027] Embodiment 2, as Figure 1 As shown, in order to reduce the transmission of operating noise of the compressor to the air conditioner casing, a mounting plate 4 is provided at the bottom of the casing, and fixing bolts 5 are welded on the mounting plate 4. The central through hole 21 of the compressor vibration damping pad is inserted into the fixing bolts 5 on the mounting plate, thereby flexibly connecting the compressor and the air conditioner base plate together. like Figure 1-5 As shown, the center hole 121 of the compressor support foot 1 is inserted into the first and second boss connecting parts 231 of the vibration-damping pad 2, and the bottom plate 12 of the support foot is placed on the second boss plane 2221, completing the connection between the compressor and the vibration-damping pad. When the compressor is running, the vibration-damping pad 2 can absorb the vibration of the compressor and reduce the outdoor noise of the air conditioner.

[0028] like Figure 1 ,2 In order to ensure reliable welding of the support legs of the compressor shown in 3, the support legs are usually moved from the bottom 31 of the cylinder to the outer peripheral wall 32 of the cylinder. The advantage is that the center of gravity of the compressor is lowered. The disadvantage is that different types of support legs are required for different cylinder 3 wall thicknesses. The thickness specifications are usually 2.8, 3.0, 3.2, and 3.5. In addition, different support legs 1 have only slight differences in the distance between the center hole 121 and the back plate 11, which is easy to cause mixing in mass production.

[0029] like Figure 2-5 As shown, the compressor L-support leg 1 and the vibration-damping pad 2 both have a double-eye structure, and through different installation directions, the compressor with different cylinder 3 wall thicknesses can be connected to the air conditioner bottom plate. This structure greatly reduces the specifications of the L-support leg 1.

[0030] like Figure 2 and Figure 3 The compressor L-support leg 1 shown is composed of two parts, a back plate 11 and a bottom plate 12, wherein the back plate 11 is connected to the outer peripheral wall of the compressor cylinder 3 by projection welding, and there is a pair of eyelets 121 on the bottom plate 12 of the L-support leg, which is connected with the shock-absorbing pad 2 in cooperation.

[0031] like Figure 4 and Figure 5 The vibration damping pad 2 for the compressor shown in the figure has a through hole 21 in the center and a plurality of bosses 22 on the periphery. The connecting portion 231 between the first boss 221 and the second boss 222 is inserted into the double eye holes 121 of the above-mentioned L-leg. The bottom plate 12 of the L-leg is placed on the second boss plane 2221, and the connecting portion 231 is also a double eye structure.

[0032] like Figure 2 and Figure 3 The compressor shown has an L-shaped support leg 1, and the centers of the two eyelets 121 are O and O' respectively, and the distance between them is a, then 0.2≤a≤0.7.

[0033] like Figure 2 and Figure 3 The compressor shown has an L-shaped support leg 1, and the center O and O' of the double eyelet 121 are connected by a line 0-0'. There is a mark 14 on the connecting line, and the mark line can be rectangular or circular.

[0034] The compressor L-support foot back plate 11 is arc-shaped, and the arc radius is R. The back plate is connected to the outer peripheral wall of the compressor cylinder 3 by projection welding. If the outer wall radius is r, then r+0.5≤R≤r+2.

[0035] like Figure 4 and Figure 5 The compressor vibration damping pad 2 shown in the figure has a connecting portion 231 of the first peripheral boss 221 and the second boss 222 with the same outer diameter as a double-eye structure, with centers A and A' respectively. There is a through hole 21 in the center of the vibration damping pad 2, and the center A of the double eyes of the connecting portion 231 coincides with the axis of the central through hole 21.

[0036] As shown Figure 4 and Figure 5 In the compressor vibration damping pad 2 shown, the distance between the centers A and A' of the double-eye structure of the outer diameter of the connecting portion 231 is b, and b=a.

[0037] As shown Figure 4 and Figure 5 In the compressor vibration damping pad 2 shown, a triangle mark 24 is required on the side close to A' of the connecting part 231, where the line connecting the centers A and A' of the double-eye structure of the outer diameter of the connecting part 231 is connected.

[0038] like Figure 6 The compressor shown uses an L-support leg 1 and a vibration-damping pad 2. When the vibration-damping pad 2 is assembled with the L-support leg 1, when the wall thickness of the cylinder 3 is relatively thick, the triangular mark 24 is installed along the L-support leg mark line 14, away from the compressor body; like Figure 7 The compressor shown in the figure uses an L-shaped support leg 1 and a vibration-damping pad 2. When the vibration-damping pad 2 is assembled with the L-shaped support leg 1, the cylinder 3 When the wall thickness is thin, the triangle mark 24 is installed along the L-leg mark line 14, close to the compressor body.

[0039] By welding fixing bolts on the mounting plate and inserting the central through hole of the vibration damping pad into the fixing bolts, a flexible connection between the compressor and the air conditioner base plate is achieved. This connection method can effectively isolate and absorb the vibration generated when the compressor is running, thereby reducing the transmission of noise to the air conditioner casing and improving user comfort.

[0040] The L-shaped support feet and vibration-damping pads are designed as double-eye structures, which allow them to be installed in different directions to meet the connection requirements of compressors with different cylinder wall thicknesses and the air conditioner base plate. This design greatly improves the adaptability and flexibility of the product and reduces the trouble of replacing different types of support feet due to different cylinder wall thicknesses.

[0041] Traditionally, different types of legs are required for different cylinder wall thicknesses. However, this embodiment uses a double-eye structure and a specific assembly method to achieve the same specification of L legs and vibration-damping pads to meet the needs of different cylinder wall thicknesses, thereby significantly reducing the types of leg specifications and reducing production and management costs.

[0042] There are marking lines or triangular marks on the L-shaped feet and vibration-damping pads, which provide clear guidance for installation. During installation, you only need to select the appropriate installation direction according to the wall thickness of the cylinder and align the marks, which greatly improves installation efficiency and accuracy.

[0043] The back plate of the L-leg is connected to the outer wall of the compressor barrel by projection welding. This connection method has high strength and stability, which can effectively support the compressor and prevent it from shaking. At the same time, the boss and connection design of the vibration-damping pad also enhance the stability of the entire structure, making the compressor more stable during operation.

[0044] The compact design of the L-feet and vibration-damping pads makes them an efficient use of space, especially inside air conditioners where space is limited. This design helps reduce the size and weight of the entire system, improving energy efficiency and environmental performance.

[0045] Precise design and manufacturing ensure that the L-legs and vibration-damping pads can firmly connect the compressor and the air conditioner base plate and maintain a stable connection under long-term operation and vibration environments. This helps improve the reliability and durability of the entire air conditioning system and reduce failures and accidents caused by loose or failed connections.

[0046] In summary, the technical solution described in Example 2 achieves multiple technical effects such as reducing noise transmission, improving adaptability and flexibility, reducing the size of the legs, improving installation efficiency and accuracy, enhancing structural stability, optimizing space utilization, and improving reliability and durability through innovative design and ingenious assembly methods. These technical effects together constitute the core value of this embodiment, bringing significant benefits to manufacturers and users of compressors and air conditioners.

[0047] Embodiment 3, the present invention further provides a compressor, which comprises the aforementioned compressor L-support foot 1 and vibration-damping pad 2.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
