Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigeration compressors, in particular to a clamp assembly and a rotor compressor. Background Art
[0002] A liquid reservoir is usually provided on the outside of the body of the rotary compressor, and the liquid reservoir needs to be connected and fixed to the body through a connector. A more common way is to use a clamp for a detachable connection. Since the compressor will vibrate during operation, directly using a clamp for a rigid connection is not conducive to vibration reduction.
[0003] In order to reduce the adverse effects of vibration, the rotary compressor will use clamps and washers at the same time. By putting them on the outer circle of the liquid reservoir and tightening them with screws, the fixed structure can prevent the compressor body from vibrating violently during the compression movement, thereby damaging the intake pipe and the liquid reservoir. The washers designed for conventional rotary compressors are basically annular structures, which need to be put on the liquid reservoir and then fixed with screws on the clamps. This washer structure is too simple and the shock-absorbing effect is not obvious. It cannot effectively prevent the clamp from loosening or relative displacement during long-term vibration. Summary of the invention
[0004] The utility model aims to provide a clamp assembly and a rotor compressor in view of the problems existing in the prior art.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A clamp assembly includes a clamp and an elastic gasket used in conjunction with the clamp; the clamp is an open structure, having a first connecting end and a second connecting end; the elastic gasket is also an open structure, having a first free end and a second free end, the outer periphery of the elastic gasket is provided with a receiving groove along the outer periphery length direction, the body of the clamp is arranged in the receiving groove, the first connecting end and the second connecting end respectively extend out of the receiving groove, and the circumferential length of the elastic gasket is not shorter than the circumferential length of the clamp.
[0007] The clamp assembly improves the structure of the elastic gasket and has better improvement effects in vibration reduction and assembly connection. When used in combination with the clamp, it can better fix the clamped object and prevent the clamped object from loosening or falling off due to vibration of the main equipment. The clamp assembly can be widely used in compressors of refrigeration equipment and refrigeration appliances.
[0008] The improvements of this elastic gasket exist in the following aspects at the same time. First, the elastic gasket is an open structure, which can be directly clamped on the fixed object, which is convenient for the installation of the elastic gasket. For the assembly of the liquid reservoir, it can reduce the assembly action of one ring and optimize the assembly process. Second, the receiving groove is set on its outer side, which can accommodate the main structure of the clamp inside the elastic gasket. This can not only increase the contact area between the vibration reduction support and the elastic support and improve the vibration reduction effect, but also form a limit on the upper and lower end faces of the clamp, which can greatly reduce the axial runout and displacement of the clamp, and the clamp is fixed more firmly. Third, its length can cover the entire main structure of the clamp, which will not allow the clamp to have a chance of direct contact with the fixed object, avoiding rigid contact. The connection method of this elastic gasket and the clamp assembly can optimize the vibration reduction while also playing a good noise reduction role.
[0009] The clamp and the elastic gasket are both open structures, which is very convenient for the matching connection and easy to assemble the entire clamp assembly. The first connecting end and the second connecting end can adopt two connection methods with different structures, and the first free end and the second free end can also be well adapted to the connecting ends of different structures to form vibration reduction protection respectively.
[0010] Furthermore, the circumferential length of the elastic gasket is longer than the circumferential length of the clamp, the first connecting end extends from the first free end of the elastic gasket, and the second connecting end extends from the side of the accommodating groove away from the second free end.
[0011] Furthermore, the first free end is tangent to the circumference of the elastic washer, and the second free end is an arc-shaped structure concentric with the circumference of the elastic washer.
[0012] Furthermore, the elastic gasket is a rubber gasket, and anti-slip layers are respectively provided on the inner side and the outer side of the rubber gasket, which can increase friction and reduce displacement or sliding caused by vibration.
[0013] Furthermore, the elastic gasket includes a ring wall, and an upper folded edge and a lower folded edge arranged on the upper and lower sides of the ring wall, and the upper folded edge, the lower folded edge and the ring wall form the accommodating groove; the width of the upper folded edge and the lower folded edge is greater than the thickness of the clamp, which can better accommodate the clamp, and the distance between the upper folded edge and the lower folded edge is not greater than the width of the clamp.
[0014] Furthermore, a plurality of elastic metal wires are distributed in the elastic gasket.
[0015] Furthermore, the first connecting end is hook-shaped, and the second connecting end is a connecting ear piece formed by bending. The connecting ear piece is provided with a connecting hole for connecting and fixing the clamp.
[0016] Another scheme provided by the utility model is: a rotary compressor with the above-mentioned clamp assembly, the rotary compressor includes a compressor body, the outer wall of the compressor body is provided with a liquid reservoir bracket, the compressor body is connected to the liquid reservoir through an air intake pipe, and the liquid reservoir is detachably connected to the liquid reservoir bracket through the clamp assembly; the elastic gasket is tightly attached to the outer periphery of the liquid reservoir, the first connecting end is hooked with one end of the liquid reservoir bracket, and the second connecting end is connected to the other end of the liquid reservoir bracket by bolts.
[0017] Compared with the prior art, the beneficial effects of the utility model are as follows: 1. The clamp assembly improves the structure of the elastic gasket, thereby having a better improvement effect in vibration reduction and assembly connection. When used in combination with the clamp, it can better fix the clamped object and prevent the clamped object from loosening or falling off due to the vibration of the main equipment. It can be widely used in compressors of refrigeration equipment and refrigeration appliances; 2. When the clamp assembly is used to fix the liquid reservoir of the refrigeration compressor, during the operation of the compressor, the negative impact of the compressor vibration on the fixed connection of the liquid reservoir can be significantly reduced, the probability of abnormal connection of the liquid reservoir is reduced, the clamp is not easy to deviate, and the damage caused by vibration to the intake and intake pipes and the liquid reservoir is basically avoided, and the service life of the compressor parts is extended. 3. The elastic gasket is of an open structure and can be directly clamped on the fixed object, which is convenient for the installation of the elastic gasket. For the assembly of the liquid reservoir, one ferrule assembly action can be reduced, thereby optimizing the assembly process; 4. The accommodating groove is arranged on the outer side of the elastic gasket, so that the main structure of the clamp can be accommodated in the elastic gasket, which not only increases the contact area between the vibration-damping support and the elastic support and improves the vibration-damping effect, but also forms a limit on the upper and lower end faces of the clamp, which can greatly reduce the axial runout and displacement of the clamp, and the clamp is fixed more firmly; it can also cover the main structure of the entire clamp, so that the clamp will not be in direct rigid contact with the fixed object, which can optimize the vibration reduction and also play a good noise reduction role.

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. Embodiment 1:
[0026] like Figure 1 to Figure 3 As shown, a clamp assembly includes a clamp 1 and an elastic gasket 2 used in conjunction with the clamp 1; the clamp 1 is an open structure, having a first connecting end 101 and a second connecting end 102; the elastic gasket 2 is also an open structure, having a first free end 201 and a second free end 202, the outer periphery of the elastic gasket 2 is provided with a receiving groove 3 along the outer periphery length direction, the body of the clamp 1 is arranged in the receiving groove 3, the first connecting end 101 and the second connecting end 102 respectively extend out from the receiving groove 3, and the circumferential length of the elastic gasket 2 is not shorter than the circumferential length of the clamp 1.
[0027] The clamp assembly improves the structure of the elastic gasket 2, thereby achieving better improvement in vibration reduction and assembly connection. When used in combination with the clamp 1, it can better fix the clamped object and prevent the clamped object from loosening or falling off due to vibration of the main equipment. The clamp assembly can be widely used in compressors of refrigeration equipment and refrigeration appliances.
[0028] For example, when the clamp assembly is used to fix the liquid reservoir of a refrigeration compressor, during the operation of the compressor, the negative impact of the compressor vibration on the fixed connection of the liquid reservoir can be significantly reduced, and the probability of abnormal connection of the liquid reservoir can be reduced, thereby improving the overall performance of the compressor.
[0029] The improvements of the elastic gasket 2 are in the following aspects: first, the elastic gasket 2 is an open structure, which can be directly clamped on the fixed object, which is convenient for the installation of the elastic gasket. For the assembly of the liquid storage device, the assembly action of one ferrule can be reduced, and the assembly process is optimized; second, the receiving groove 3 is arranged on its outer side, which can accommodate the main structure of the clamp 1 in the elastic gasket 2, which can not only increase the contact area between the vibration reduction support and the elastic support and improve the vibration reduction effect, but also form a limit on the upper and lower end faces of the clamp, which can greatly reduce the axial runout and displacement of the clamp, and the clamp is fixed more firmly; third, its length can cover the main structure of the entire clamp 1, which will not allow the clamp 1 to have a chance to directly contact the fixed object, avoiding rigid contact. The connection method of the elastic gasket 2 and the clamp 1 can optimize the vibration reduction while also playing a good noise reduction role.
[0030] The clamp 1 and the elastic gasket 2 are both open structures, which is very convenient for the matching connection and easy to assemble the entire clamp assembly. The first connecting end 101 and the second connecting end 102 can adopt two connection methods with different structures, and the first free end 201 and the second free end 202 can also be well adapted to the connecting ends of different structures to form protection respectively.
[0031] Furthermore, the circumferential length of the elastic washer 2 is longer than that of the clamp 1, the first connection end 101 extends from the first free end 201 of the elastic washer, and the second connection end 102 extends from the side of the receiving groove 3 slightly away from the second free end 202 (for example, extending from a position 30-50 mm away from the end of the second free end). Such a structure can better clamp and fix the object to be connected while playing a role in vibration reduction and protection.
[0032] Furthermore, the first free end 201 is tangent to the circumference of the elastic gasket 2 itself, and the second free end 202 is an arc-shaped structure concentric with the circumference of the elastic gasket 2, that is, it is a part of itself.
[0033] The first connection end 101 is hook-shaped, and the second connection end 102 is a connection ear piece formed by bending. The connection ear piece is provided with a connection hole 7.
[0034] Through the arrangement of the above structure, the first free end 201 can well allow the hook-shaped first connecting end 101 to extend from its receiving groove, and the second free end 202 can better approach the object to be engaged, and after assembly, it is as close to the first free end 201 as possible to form a nearly closed loop (actually not closed); the bent second connecting end 102 can more conveniently connect screws, bolts and other connecting parts.
[0035] In some embodiments, the elastic gasket 2 is a rubber gasket, and an anti-slip layer is provided on the inner side and the outer side of the rubber gasket respectively.
[0036] The anti-slip layer can be arranged in the receiving groove or its annular peripheral wall, and can be an anti-slip pattern formed by rolling, or an array of small dot-shaped protrusions; it can form a greater friction force between the clamp and the clamp to avoid relative movement between the clamp and the elastic gasket due to vibration, and can also increase the friction between the clamped object to avoid relative movement of the elastic gasket.
[0037] Furthermore, the elastic gasket 2 includes a ring wall 4, and an upper folded edge 5 and a lower folded edge 6 arranged on the upper and lower sides of the ring wall 4, and the upper folded edge 5, the lower folded edge 6 and the ring wall 4 form the accommodating groove 3; the width of the upper folded edge 5 and the lower folded edge 6 is greater than the thickness of the clamp 1, and the distance between the upper folded edge 5 and the lower folded edge 6 is slightly smaller than the width of the clamp 1.
[0038] By using the wider upper folded edge and the wider lower folded edge, the clamp can be completely wrapped, so that the clamp is difficult to be separated from the accommodating groove during long-term vibration.
[0039] In some embodiments, the thickness of the clamp is 0.8-2 mm, preferably 1 mm; the width of the clamp is 8-15 mm, preferably 10 mm; the wall thickness of the elastic gasket is 1.5-3 mm, preferably 2 mm; the depth of the accommodating groove is 3-5 mm, preferably 3.2 mm.
[0040] In some embodiments, a plurality of elastic metal wires are distributed in the elastic gasket 2. The elastic metal wires can be respectively in the upper hem and the lower hem, which can enhance the strength and toughness of the upper hem and the lower hem, so that the accommodating groove has a good limiting effect. Embodiment 2:
[0041] Another solution provided by the utility model is: Figure 4 and Figure 5As shown, a rotary compressor with the above-mentioned clamp assembly, the rotary compressor includes a compressor body 8, the outer wall of the compressor body 8 is provided with a liquid reservoir bracket 11, the compressor body 8 is connected to the liquid reservoir 10 through the intake and exhaust pipes 9, the liquid reservoir 10 is detachably connected to the liquid reservoir bracket 11 through the clamp assembly; the elastic gasket 2 is tightly attached to the outer periphery of the liquid reservoir 10, the first connecting end 101 is hooked with one end of the liquid reservoir bracket 11, and the second connecting end 102 is connected to the other end of the liquid reservoir bracket 11 through a bolt 12.
[0042] Through the above connection, the upper half of the liquid reservoir 10 can be well clamped and fixed on the liquid reservoir bracket 11. During the assembly process, there is no need to insert the elastic gasket 2 and the clamp 1 into the liquid reservoir 10 from top to bottom, and they can be directly clamped from the outer wall, which improves the efficiency of compressor production; the connected clamp 1 can be well limited. During the operation of the compressor, there is rarely any relative displacement between the clamp 1, the elastic gasket 2 and the liquid reservoir 10. The clamp 1 is not easy to deviate, and the vibration reduction and noise reduction effect is excellent. Damage to the intake pipe and the liquid reservoir due to vibration is basically avoided, and the service life of the compressor parts is longer.
[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
