Description

Technical Field

[0001] This invention relates to the field of connection and fixing technology, and particularly to fixing structures and compressors. Background Technology

[0002] As a crucial component of rotary compressors, the liquid receiver is typically fixed to the compressor housing using a U-shaped bracket, clamps, rubber pads, etc., welded to the housing. Usually, two parallel clamps connect the liquid receiver simultaneously, one above the other. This connection method is not only inconvenient to use, but also results in the two clamps acting independently without forming a mutually restraining structure. Consequently, the shock absorption effect is poor, the strength is low, and the liquid receiver is prone to excessive vibration or loosening under the influence of compression vibration. Summary of the Invention

[0003] To address the problems of inconvenient connection and poor fixation of liquid reservoirs, this invention proposes a fixing structure that utilizes an adjustable clamp structure to combine two clamp structures together, which not only facilitates connection but also improves shock absorption and fixation performance.

[0004] The technical solution adopted in this invention is to design a fixed structure, including two fixed support members located on one side of the object to be fixed and an adjustable support member located on the other side of the object to be fixed. The two fixed support members and the adjustable support member are respectively connected by clamps, the clamps surround the object to be fixed, and the adjustable support member has a top pressure part that can be extended and adjusted toward the object to be fixed.

[0005] In some embodiments, the adjustable support includes a connecting part fixedly connected to the clamp, a sliding sleeve is provided on the connecting part, the pressing part includes a telescopic rod slidably fitted in the sliding sleeve, and a locking mechanism is provided between the telescopic rod and the sliding sleeve, the locking mechanism enabling the telescopic rod and the sliding sleeve to be temporarily fixed in relative position.

[0006] In some embodiments, the locking mechanism includes a plurality of insertion holes extending along the length of the sliding sleeve and a positioning rod that can be inserted into the insertion holes. The telescopic rod is provided with a positioning hole corresponding to the insertion hole. The positioning rod passes through both the insertion hole and the positioning hole to fix the position of the telescopic rod relative to the sliding sleeve.

[0007] In some embodiments, the telescopic rod has locking portions at both ends to prevent the telescopic rod from sliding out of the sliding sleeve.

[0008] In some embodiments, the sliding sleeve is provided with several guide holes in its circumferential direction, and a guide rod is slidably fitted in the guide holes, with both ends of the guide rod connected to the locking part.

[0009] In some embodiments, an elastic strip opposite to the top pressure portion is connected between the two fixed supports, the elastic strip having an arch shape toward the top pressure portion.

[0010] In some embodiments, the two fixing supports include saddle-shaped buffer portions, each including a fitting portion that matches the contour of the surface of the object being fixed, the fitting portion having a buffer layer that supports the surface of the object being fixed.

[0011] In some embodiments, the two fixed supports are further connected to clamps located on both sides of the adjustable support, the clamps being used to tighten the fixed object.

[0012] In some embodiments, the clamp includes an inner ring and an outer ring, and a shock-absorbing spring is supported between the inner ring and the outer ring. The shock-absorbing spring is a cylindrical spring, and the length direction of the cylindrical spring is arranged along the arc length direction of the gap between the inner ring and the outer ring.

[0013] In some embodiments, the two ends of the cylindrical spring are fixedly connected to the clamp. From the end of the cylindrical spring toward the middle, three adjacent elastic coils of the cylindrical spring are arranged in a group, and the included angle between the three elastic coils in each group is 20-40°, 80-100°, and 45-65° respectively.

[0014] In some embodiments, the clamp includes two opposing locking arms, one end of which is detachably connected to the fixed support and the other end of which is connected to the housing support.

[0015] In some embodiments, the locking arm includes an inner plate and an outer plate relative to the object being fixed, and a shock-absorbing spring is provided between the inner plate and the outer plate. The shock-absorbing spring is a cylindrical spring, and the length direction of the cylindrical spring is arranged along the length direction of the gap between the inner plate and the outer plate.

[0016] The compressor includes a liquid receiver, which is fixed to the compressor by the aforementioned fixing structure.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Adjusting the tightness of the reservoir by adjusting the extension and retraction of the top pressure part also facilitates the insertion of the reservoir into the clamp and then quickly fixing it. The adjustable support allows the two clamps to be connected together, which helps to resist radial and circumferential vibrations simultaneously without affecting the fixation.

[0019] 2. The rotary compressor receiver vibration damping and fixing device designed in this invention fixes the receiver with a saddle bracket and a locking arm, which can not only prevent the compressor body and the receiver from vibrating together and ensure operational stability, but also effectively suppress the radial and circumferential vibration of the receiver in the compressor housing, reducing the difficulty of layout caused by large vibration of the compressor piping.

[0020] 3. The saddle bracket of the rotary compressor receiver vibration damping and fixing device designed in this invention has good rigidity, and the installation modal frequency of the receiver is much greater than the rotational frequency and double frequency of the ordinary compressor, which effectively avoids the resonance problem of the receiver. Therefore, it is also suitable for the vibration damping and fixing of the receiver of high speed compressors. Attached Figure Description

[0032] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments, and the following embodiments do not limit the invention covered by the claims. Furthermore, not all combinations of the features described in the embodiments are necessary for the inventive solution.

[0033] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0034] Example 1

[0035] The vibration and noise of rotary compressors mainly originate from two aspects: exhaust vibration and mechanical vibration. Vibration and noise caused by airflow impact can be controlled through silencers, while vibration reduction and noise reduction of the compressor body are generally achieved through vibration-damping rubber pads. The receiver, as a crucial component of a rotary compressor, is typically fixed to the compressor housing using a U-shaped bracket, clamps, rubber pads, etc., to reduce its circumferential vibration. However, due to insufficient rigidity of the U-shaped bracket structure in the circumferential direction, the receiver's fixation is poor, and the lack of effective vibration damping measures means that the receiver's swaying in the circumferential direction is not effectively suppressed, easily leading to problems such as receiver outlet pipe cracking and excessive compressor piping vibration.

[0036] Existing patent CN218955227U discloses a liquid receiver connection device. This device adds a damping spring at the rotating joint to reduce vibration in the conventional liquid receiver fixing method, and can be used in combination. The damping mechanism of this technical solution is simple, the damping effect is not obvious, and the added rotating and adjustable bracket has poor reliability. Existing patent CN105402129A discloses a compressor liquid receiver clamp bracket, which is rigidly fixed to the compressor by the bracket, which helps to solve the strain problem of the L-shaped tube at the bottom of the liquid receiver. However, the liquid receiver vibrates with the compressor as a whole, which increases the difficulty of compressor piping.

[0037] As a crucial component of rotary compressors, the liquid receiver is typically fixed to the compressor housing using a U-shaped bracket, clamps, rubber pads, etc., welded to the housing. Usually, two parallel clamps connect the liquid receiver simultaneously, one above the other. This connection method is not only inconvenient to use, but also results in the two clamps acting independently without forming a mutually restraining structure. Consequently, the shock absorption effect is poor, the strength is low, and the liquid receiver is prone to excessive vibration or loosening under the influence of compression vibration.

[0038] To address the problems of inconvenient connection and poor fixation of liquid reservoirs, this invention proposes a fixing structure that utilizes an adjustable clamp structure to combine two clamp structures together, which not only facilitates connection but also improves shock absorption and fixation performance.

[0039] like Figure 1 ,2 As shown, the fixing structure 1 is used to fix the liquid reservoir 21 of the rotary compressor 2 and reduce vibration and noise radiation. The fixing structure includes two fixed supports on one side of the liquid reservoir and an adjustable support on the other side of the liquid reservoir. The two fixed supports and the adjustable support are connected by clamps, which surround the liquid reservoir. The adjustable support has a top pressure portion that can be adjusted to extend or retract toward the liquid reservoir. This allows for adjustment of the tightness of the liquid reservoir by adjusting the extension or retraction of the top pressure portion, and also facilitates the insertion of the liquid reservoir into the clamps for quick fixing. The adjustable support connects the two clamps together, which helps to resist radial and circumferential vibrations simultaneously without affecting the fixation.

[0040] The adjustable support includes a connecting part that is fixedly connected to the clamp, and a sliding sleeve is provided on the connecting part. The pressing part includes a telescopic rod that is slidably fitted in the sliding sleeve. A locking mechanism is provided between the telescopic rod and the sliding sleeve. The locking mechanism can temporarily fix the relative position of the telescopic rod and the sliding sleeve, thereby fixing the telescopic rod through the locking mechanism.

[0041] like Figure 5 , 6 As shown in Figure 7, the locking mechanism includes several fixing holes arranged along the length of the telescopic rod and a positioning rod that can be inserted into the fixing holes. The sliding sleeve is provided with a socket corresponding to the fixing hole. The positioning rod passes through both the socket and the fixing hole to fix the position of the telescopic rod relative to the sliding sleeve. Different sockets are different positions, and the positioning rod is firmly positioned with the socket.

[0042] The telescopic rod has locking portions at both ends to prevent it from sliding out of the sliding sleeve. The clamp includes two opposing locking arms, one end of which is detachably connected to the fixed support to facilitate the installation of the liquid reservoir, and the other end is connected to the housing support.

[0043] The sliding sleeve is provided with several guide holes in its circumference. A guide rod slides in the guide holes and is connected to the locking part at both ends. In this embodiment, there are four guide holes, and each locking arm end is connected to one of the guide holes, which makes the fixation firm and has a good guiding effect on the extension and retraction of the telescopic rod.

[0044] like Figure 8 , 9As shown in Figure 10, an elastic strip is connected between the two fixed supports, opposite to the top pressure portion. The elastic strip has an arch shape facing the top pressure portion, and the arched portion provides elastic clamping for the reservoir. The elastic strip is a leaf spring 114. The two fixed supports include saddle-shaped buffer portions, each including a fitting portion that matches the surface contour of the reservoir. The fitting portion has a buffer layer supporting the surface of the reservoir, thus providing a certain buffering and shock absorption effect for the reservoir. The saddle-shaped buffer portion is a saddle bracket 11, including an upper saddle bracket 111 and a lower saddle bracket 112. The upper saddle bracket 111 and the lower saddle bracket 112 are metal parts. The left concave surface of the saddle bracket 11 is welded and fixed to the rotary compressor 2. The adjustable support 12 is fixed to the end of the locking arm in the locking arm 132. The locking arm 132 and the saddle bracket 11 are fixed by welding, riveting, or detachable connection. The buffer layer is a rubber pad 115, which is bonded to the upper saddle bracket 111 and the lower saddle bracket 112 via a metal-rubber vulcanization process. The leaf spring 114 is fixed to the upper saddle bracket 111 and the lower saddle bracket 112 by welding or riveting through pads 113 at both ends. The saddle bracket 11 is tightly fitted to the liquid reservoir 21 through the rubber pad 115 and secured by the locking arm 132. The leaf spring 114 provides initial elasticity to the liquid reservoir 21, and to a certain extent, the leaf spring 114 and the rubber pad 115 can also reduce the radial vibration amplitude of the liquid reservoir on the compressor housing. In the saddle-type support 11, 111 is the upper saddle-type support, 112 is the lower saddle-type support, 113 is a pad, 114 is a leaf spring, and 115 is a rubber pad; in the upper saddle-type support 111, 1111 is a stiffening plate, and 1112 is a bending plate. In the saddle-type support, the angle of the fan-shaped area on the side that contacts the liquid reservoir 21 is A.

[0045] like Figure 3 , 4 As shown, the structural features of the saddle bracket 11 give it excellent installation rigidity: the upper saddle bracket 111 and the lower saddle bracket 112 are symmetrical structures, as are the locking arms 132 connected to them, and the distance between them is at least half the height of the reservoir; taking the upper saddle bracket 111 as an example, the angle A of the fan-shaped area on the side that is in contact with the reservoir 21 is 100-130°; and the saddle bracket stiffeners 1111 are arranged in a trapezoidal layout to support the end of the bent plate 1112. Therefore, the installation modal frequency of the reservoir is much greater than 300Hz, avoiding the resonance problem of the reservoir. Similarly, the device of the present invention is also suitable for vibration reduction and fixation of the reservoir of high-speed compressors.

[0046] The adjustable support component includes a main block 121 and a sliding block 122. The sliding block 122 can be assembled to the guide rod 1211 inside the main block 121 through the guide hole 1221. The sliding block 122 can slide freely within the main block 121 to adjust its position. A bolt 124 can be riveted to the main block 121 through the insertion hole 1222 and the fixing hole 1212 of the main block 121. A locking part 1213 is fixed to the guide rod 1211, forming the adjustable support component 12. The rubber pad 123 is joined to one end face of the main block 121 using a metal-rubber vulcanization process. In the adjustable support component 12, 121 is the main block, 122 is the sliding block, 123 is the rubber pad, and 124 is the bolt. In the main block 121, 1211 is the guide rod, 1212 is the fixing hole, and 1213 is the locking part. In the sliding block 122, 1221 is the guide hole, and 1222 is the insertion hole.

[0047] The two fixed support members are also connected to clamps located on both sides of the adjustable support member. The clamps are used to tighten the liquid reservoir, clamp and fix it, and improve the buffer stiffness.

[0048] The clamp includes a concentric inner ring 1313 and an outer ring 1311, both of which are elastic metal plates. A shock-absorbing spring 1312 is supported between the inner and outer rings. The shock-absorbing spring is a cylindrical spring, and its length is along the arc length of the gap between the inner and outer rings, thereby improving the clamp's elasticity and providing better shock absorption performance. 1311 is a semi-circular elastic plate, 1312 is an elastic ring, and 1313 is a rubber pad. Within the semi-circular elastic plate 1311, the angle between the first or last elastic ring and its adjacent elastic ring is B, the angle between the second and third elastic rings is C, and the angle between the third and fourth elastic rings is D. R is the radius of the semi-circular locking arm 13 when it clamps the liquid reservoir 21, which is also the radius of the liquid reservoir 21.

[0049] Both ends of the cylindrical spring are fixedly connected to the clamp. From the ends of the cylindrical spring towards the center, three adjacent elastic coils are arranged sequentially as a group. The included angles between the three elastic coils in each group range from 20-40°, 80-100°, to 45-65°. This angle arrangement better complements the clamp's vibration damping function. The placement angle B between the first or last elastic coil and its adjacent elastic coil is 20-40°; the placement angle C between the second and third elastic coils is 80-100°; the placement angle D between the third and fourth elastic coils is 45-65°, and subsequent elastic coils are arranged and fixed sequentially according to the angles specified for the second, third, and fourth elastic coils. The above angles represent the angle ranges of the semi-circular clamp 131 under static, stretched, and bent working states.

[0050] The locking arm includes an inner plate 1321 and an outer plate 1322 relative to the liquid reservoir. A shock-absorbing spring is provided between the inner plate and the outer plate. The shock-absorbing spring is a cylindrical spring, and its length direction is along the length direction of the gap between the inner plate and the outer plate, thereby improving the elasticity of the clamp and providing better shock absorption performance. 1321 and 1322 are inclined elastic plates, 1323 is an elastic ring, 1324 is a rubber pad, and 13211 has fixing holes on the inclined elastic plate.

[0051] The inner plate also has a rubber pad 1324, which is bonded to the inner plate 1321 by a metal-vulcanization process. The fixing hole 13211 of the inner plate 1321 engages with the slider 122 through the opening of the guide hole 1221. When the slider 122 is inserted into the main block 121 and the clamp 131 tightens the liquid reservoir 21, the radius of the arc is R. Similarly, R is also the radius of the circular cross-section of the liquid reservoir.

[0052] The initial lengths of clamp 131 and locking arm 132 are respectively half the circumference of the liquid reservoir's circular cross-section. Perimeter of a 1 / 4 circular cross section 60-85%. When the locking arm 132, in conjunction with the adjustable support 12 and the saddle bracket 11, fixes the liquid reservoir to the compressor, the clamp 131 has an initial tensile deformation, that is, the initial deformation length of the clamp 131 is 1 / 2 the circumference of the circular cross-section of the liquid reservoir. The initial deformation length of the locking arm 132 is 15-40% of the perimeter of the reservoir's circular cross-section. At 15-40%, the reservoir vibration damping and fixing device 1 has sufficient rigidity to achieve the fixing effect. The clamping force of the locking arm 132, combined with the rigidity of the saddle bracket 11, can avoid the problem of excessive circumferential swing of the reservoir in the compressor housing under conventional clamp conditions.

[0053] The rotational vibration of the compressor is transmitted to the liquid receiver through the bracket. The radial and circumferential vibration of the liquid receiver in the compressor housing can be effectively reduced by the locking arm 132. These leaf springs, semi-circular elastic plates, inclined elastic plates, elastic rings and rubber pads can all absorb the vibration energy of the liquid receiver.

[0054] The inclined elastic plates 1321 and 1322 of the aforementioned locking arm 132 can slide and adjust with the sliding block 122 of the adjustable support 12, changing the initial deformation of the claw-shaped locking arm 132, that is, adjusting its stiffness. This can achieve consistency in stiffness between the semi-circular locking arm 131 and the claw-shaped locking arm 132, avoiding the problem of unsatisfactory vibration reduction effect caused by asynchronous force when the split vibration damping elastomers work together.

[0055] The rotary compressor receiver vibration damping and fixing device designed in this invention fixes the receiver with a saddle bracket and a locking arm, which can not only prevent the compressor body and the receiver from vibrating together and ensure operational stability, but also effectively suppress the radial and circumferential vibration of the receiver in the compressor housing, reducing the difficulty of layout caused by large vibration of the compressor piping.

[0056] The saddle bracket of the rotary compressor receiver vibration damping and fixing device designed in this invention has good rigidity, and the installation modal frequency of the receiver is much greater than the rotational frequency and second harmonic of a typical compressor, which effectively avoids the resonance problem of the receiver. Therefore, it is also suitable for the vibration damping and fixing of the receiver of high-speed compressors.

[0057] This invention designs a vibration damping and fixing device for a rotary compressor receiver. It uses a claw-type locking arm, supplemented by a semi-circular locking arm, to suppress vibration in the receiver. The claw-type locking arm, through an adjustable support, ensures uniform stiffness among the vibration damping components, fully utilizing their damping capabilities. This patent discloses a vibration damping and fixing structure for a rotary compressor receiver. A saddle-type bracket provides limiting, while the locking arm provides damping and fixing, achieving both radial and circumferential vibration damping of the receiver. The locking arm designed in this invention consists of an elastic plate and elastic rings, with the elastic rings arranged alternately at a certain angle, effectively performing vibration damping under tension and bending conditions. The adjustable support allows for adjustment of the stiffness of the claw-type locking arm, which, combined with the semi-circular locking arm, enhances the effect and achieves uniform stiffness through the use of various elastic straps. The saddle-type bracket structure designed in this invention has excellent rigidity. The saddle-type bracket fits the receiver at a specified wrapping angle, and, in conjunction with the locking arm, provides fixing and constraint, balancing installation stiffness and vibration damping performance.
