[0027] See also Figure 1-3 As shown, a fixing clamp 14 assembly includes a fixing structure 1 and a mounting structure 3, wherein the fixing structure 1 is used to fix a structure to be fixed 1; the number of fixing structures 1 is set to at least two; a first vibration reduction structure 2 is arranged between two adjacent fixing structures 1; the mounting structure 3 includes a first mounting structure 313 and a second mounting structure 323; one of the two adjacent fixing structures 1 is a first fixing structure 111, and the other fixing structure 1 is a second fixing structure 121; the first fixing structure 111 is connected to the first mounting structure 313, the second fixing structure 121 is connected to the second mounting structure 323, and the first mounting structure 313 is slidably connected to the second mounting structure 323. In the present application, when the structure to be fixed 1 drives the first vibration reduction structure 2 to vibrate, the first mounting structure 313 and the second mounting structure 323 can slide within a certain range, which can effectively play a corresponding vibration reduction role. By arranging the first vibration reduction structure 2 between the two adjacent fixing structures 1, the structure to be fixed 1 fixed in the first fixing structure 111 and the second fixing structure 121 can be damped, and the damping effect is better. The first vibration reduction structure 2 is used for vibration reduction. It can be made of relevant materials with vibration reduction characteristics such as damping and rubber. It can meet relevant design requirements for different actual use environments, achieve relevant vibration reduction purposes from different aspects, improve the overall stability of the structure, and reduce the amplitude.

[0028] The present application also discloses some embodiments, wherein the first vibration reduction structure 2 includes an elastic member; the corresponding elastic member simultaneously generates elastic force in the direction of approaching two adjacent fixed structures 1; that is, the elastic member can be in a compressed state and simultaneously generate repulsive forces to both sides of the two adjacent fixed structures 1. The elastic member is a spring.

[0029] The present application also discloses some embodiments, in which the corresponding elastic members simultaneously generate elastic force in a direction away from two adjacent fixed structures 1, that is, the elastic members can be in an extended state and simultaneously generate a pulling force toward the middle of the two adjacent fixed structures 1. The elastic members have a larger deformation amount during actual use of vibration reduction, and can bear a wider range of elastic deformation.

[0030] The present application also discloses some embodiments, wherein the elastic member includes a first elastic member 21 and a second elastic member 22, wherein the corresponding first elastic member 21 generates elastic force in the direction close to two adjacent fixed structures 1 at the same time; and the corresponding second elastic member 22 generates elastic force in the direction away from two adjacent fixed structures 1 at the same time. The vibration of the fixed structure 1 will be directly transmitted to the mounting structure 3, and the most important intuitive manifestation is lateral vibration (small reciprocating shaking). The elastic member is to constrain and consume this part of energy. The two fixed structures 1 constrain only lateral movement. The first elastic member 21 and the second elastic member 22 have opposite constraining forces and can constrain each other to consume energy; the first elastic member 21 is a first spring, and the second elastic member 22 is a second spring. The first spring and the second spring extend from the first fixed structure 111 to the direction close to the second fixed structure 121. The number of elastic members can also be changed according to actual needs, such as one first elastic member 21 and one second elastic member 22, or two first elastic members 21, three or more second elastic members 22, etc.

[0031] The present application also discloses some embodiments, in which the number of the second elastic members 22 is set to two, the two second elastic members 22 are respectively arranged on both sides of the first elastic member 21, and the elastic force generated by the two second elastic members 22 is balanced with the elastic force generated by the first elastic member 21.

[0032] The present application also discloses some embodiments, in which the elastic forces generated by the first elastic member 21 and the second elastic member 22 are parallel to each other and in opposite directions. The elastic force of a single second elastic member 22 is smaller than the elastic force of the first elastic member 21, and the elastic forces of the two second elastic members 22 can offset each other with the elastic force generated by the first elastic member 21. That is, a larger repulsive spring in the middle provides repulsive force to the fixed clamps 14 at both ends, while the two smaller attraction springs on both sides provide attraction to offset the repulsive force formed by the repulsive springs to form a balance. When the pipeline vibrates, part of the vibration triggers the elastic force of the spring through the fixed clamp 14, which continuously offsets it, and what is reflected outside is the reduction of vibration. Rapid reduction of vibration can also ensure that the strain effect of stress on the pipeline is within the tolerance range of the pipeline, thereby ensuring reliable operation of the pipeline.

[0033] The present application also discloses some embodiments, in which the elastic member is connected to both the first mounting structure 313 and the second mounting structure 323. That is, when the elastic member vibrates, it can drive the first mounting structure 313 and the second mounting structure 323 to slide relative to each other. The fixing hooks at both ends of the elastic member are fixed to the relevant fixing columns and tightened with bolts to prevent slipping, and the convex and concave grooves on the inner fixing clamp 14 are designed to constrain the overall movement to be maintained along the axial direction of the spring to avoid torsional fracture of the pipeline. The present application achieves vibration reduction on the pipeline connecting the vibration source components of the whole machine and other components. The multiple vibration isolation design of this fixing clamp 14 reduces the vibration transmission between different components of the whole machine to a minimum, thereby achieving the design purpose of reducing the vibration value and ensuring the normal, reliable, efficient and safe operation of the unit.

[0034] The present application also discloses some embodiments, in which a first groove 311 is provided on the first mounting structure 313, and a second groove 321 is provided on the second mounting structure 323. The notches of the first groove 311 and the second groove 321 are arranged opposite to each other to form a mounting cavity, and an elastic member is arranged in the mounting cavity. The first groove 311 has a first opening, and the first opening is arranged adjacent to the notch of the first groove 311. A first cover body 41 is provided on the first groove 311, and the first cover body 41 is arranged on the first opening. The first cover body 41 is detachably connected to the first mounting structure 313, such as by a hook connection; the second groove 321 has a second opening, and the second opening is arranged adjacent to the notch of the second groove 321. A second cover body 42 is provided on the second groove 321, and the second cover body 42 is arranged on the second opening. The second cover body 42 is detachably connected to the second mounting structure 323, such as by a hook connection.

[0035] The present application also discloses some embodiments, in which the first mounting structure 313 is partially located in the second groove 321, a guide structure 312 is provided on the first mounting structure 313, a guide rail 322 is provided on the inner wall of the second groove 321, the guide structure 312 is movably provided on the guide rail 322, and the guide rail 322 extends in a direction away from the first mounting structure 313. The guide rail 322 is a slide groove, which is provided on the side wall of the second groove 321, and the guide structure 312 is a protrusion, which is adapted to the slide groove, and the concave-convex matching of the slide groove is used to realize the operation constraint, and the spring with appropriate stiffness is selected and used to ensure that when the transverse pipeline vibrates, the two inner fixing clamps 14 of the fixing clamp 14 can be constrained within a certain range without worrying about the instability of the structure, and by maintaining the transverse buffering of the vibration of the vibration-reducing fixing clamp 14, the stability of the overall structure is constrained to enhance the strength and reduce the amplitude. The guide rail 322 structure with concave-convex matching has a stronger advantage in the transverse limit of the overall structure, and can improve the stability of the fixed structure 1 during the vibration reduction process.

[0036] The present application also discloses some embodiments, in which the first mounting structure 313 is disposed on the outer peripheral wall of the first fixing structure 111 and extends in a direction approaching the second fixing structure 121 .

[0037] The present application also discloses some embodiments, in which the second mounting structure 323 is arranged on the outer peripheral wall of the second fixed structure 121 and extends in the direction close to the first fixed structure 111. In this way, the length of the fixed structure 1 of the present application can be set longer in the axial direction to better fix the structure to be fixed 1. The installation conditions of the device of the present application are less restricted, and different models (different structural designs or matching suitable second vibration reduction structures 15) can be developed to match various pipelines. It has strong environmental adaptability and life, and is very suitable for current related vibration reduction designs.

[0038] The present application also discloses some embodiments, wherein the fixing structure 1 comprises a fixing clamp 14 and a second vibration-damping structure 15, wherein the fixing clamp 14 is clamped outside the second vibration-damping structure 15; a fixing hole 13 is provided on the second vibration-damping structure 15, and the fixing hole 13 is used to install the structure to be fixed 1. The second vibration-damping structure 15 and the fixing clamp 14 are connected in a concave-convex manner, and the second vibration-damping structure 15 is made of rubber. When the rubber is cast, a relevant boss is designed on the mold, and a hole is opened on the fixing clamp 14. When installed, the boss of the second vibration-damping structure 15 is installed in the hole on the fixing clamp 14, so as to achieve a fixed constraint effect, prevent the rubber from sliding, and indirectly play an effect of constraining the longitudinal movement of the pipeline.

[0039] The present application also discloses some embodiments, in which the fixing clamp 14 includes a first clamp body and a second clamp body that cooperate with each other to have a clamping function, the first clamp body and the second clamp body are detachably connected, and the mounting structure 3 is connected to the first clamp body in an integral manner. The detachable design can be reused within the allowable range of material fatigue strength, is easy to install, and achieves vibration reduction of the vibration source module on the transmission path; in response to the adverse consequences caused by stress, the present application can perform relevant reductions when the pipeline is deformed by force, and protect the pipeline to work normally under relevant requirements. The fixing clamp 14 is made of metal material. The present application adopts a mixed design of metal and rubber, which can be used efficiently in various harsh environments such as high humidity, high salt fog, high dust, etc., and achieves high reliability vibration reduction requirements. The first clamp body and the second clamp body can be connected by a snap. The first clamp body and the second clamp body are respectively provided with a first through hole and a second through hole, and the pin 7 passes through the first through hole and the second through hole to fasten the first clamp body and the second clamp body together. Both ends of the pin 7 can be locked by a locking clip 6, one end of the locking clip 6 is locked with the first end of the pin 7, and the other end of the locking clip 6 is locked with the second end of the pin 7, so that the balance constraint of the force in the actual work of the spring can be achieved.

[0040] The present application also discloses some embodiments, and the structure to be fixed 1 is a pipeline structure. In the present application, pipeline vibration can be reduced, stress and strain can be reduced, elastic parts and rubber vibration reduction structures are combined with the limiters in various places, and the pipeline is constrained by rubber vibration reduction to prevent the pipeline from sliding when the unit is running, so as to ensure that the spring structure can play a corresponding vibration reduction role. Due to the rubber material, it can also maintain a certain elasticity to reduce the vibration between pipelines; through the tension spring and repulsion spring of the spring vibration reduction module, a vibration reduction is achieved when the vibration source module is working. Its "guide rail 322 design" strengthens the stability of the neat structure and enhances the constraint effect on the basis of its vibration buffer. The design integrates the comprehensive vibration reduction design of rubber and spring units, which can reduce the transmission of vibration in the pipeline and reduce the resonance between pipelines, and finally achieves the vibration reduction effect for the pipeline, reduces the amplitude, reduces stress and strain to ensure the normal operation of the whole machine.

[0041] The second vibration reduction structure 15 is made of rubber, and the second vibration reduction structure can be a vibration pad. The main function of the rubber vibration reduction design and the elastic member vibration reduction structure is to reduce the vibration of the fixed pipeline through the elastic deformation inside the fixing clamp 14 when it is subjected to force vibration, thereby ensuring the safety of the pipeline and reducing the transmission of vibration in the pipeline. The pipeline is stabilized at a certain position through the friction between the second vibration reduction structure 15, i.e., the fixing rubber, and the pipeline. When the refrigeration device is running, when the relevant vibration is transmitted from the upper component to the next component through the copper tube, its vibration can be reduced through the structure of the present application. The second vibration reduction structure 15, i.e., the material characteristics of the fastening rubber itself can buffer the relevant vibration, and the unbuffered part drives the relevant fixing clamp 14 to vibrate. At this time, the spring unit inside the fixing clamp 14 will consume this part of the vibration energy, promoting the rapid reduction of vibration step by step. This related vibration limited to the fixing clamp 14 has a limiting effect on the actual vibration amplitude of the pipeline, which can effectively reduce the amplitude, restore the pipeline vibration as soon as possible, and curb the vibration transmission of the pipeline. The second vibration-damping structure 15 includes a first vibration-damping rubber and a second vibration-damping rubber, which enclose a fixing hole 13 .

[0042] The mounting structure 3 of the present application is also made of metal; that is, except for the second vibration reduction structure 15 which is made of rubber, all other parts are made of metal. The present application has a better lifespan guarantee than traditional pure rubber and plastic products. The specific installation method of the present application is to clamp the fixing clip 14 outside the second vibration reduction structure 15, that is, to connect the first clip body and the second clip body, and then cover the first opening with the first cover body 41, and cover the second opening with the second cover body 42.

[0043] According to an embodiment of the present application, a heat exchange system is provided, including a fixing clamp assembly, wherein the fixing clamp assembly is the above-mentioned fixing clamp assembly. The heat exchange system may be a refrigeration device or a heat pump system.

[0044] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.
