The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0031] like Figure 1 and Figure 2 As shown, in the first aspect, an embodiment of the present application provides a pipe crimper 1, which includes a pipe crimping plate body 11, a first connecting plate portion 12 and a second connecting plate portion 13, and can quickly and accurately fix the pipeline, thereby reducing the labor burden and improving the installation and fixing efficiency.

[0032] Here, the tube pressing plate body 11 is suitable for enclosing the outlet tube cavity with a fixed foundation such as a mounting bracket, and the pipeline is fixed in the outlet tube cavity by using the tube pressing plate body 11. The first connecting plate part 12 and the second connecting plate part 13 are respectively arranged at opposite ends of the tube pressing plate body 11, and the first connecting plate part 12 and the second connecting plate part 13 are suitable for connecting and fixing with the fixed foundation, so that the tube pressing device 1 is fixed on the fixed foundation.

[0033] Here, the plane where the first connecting plate portion 12 is located is located between the top of the tube pressing plate body 11 and the second connecting plate portion 13. In this way, the first connecting plate portion 12 is closer to the top of the tube pressing plate body 11, so that the first connecting plate portion 12 is located at a higher position, and the second connecting plate portion 13 is farther away from the top of the tube pressing plate body 11, so that the second connecting plate portion 13 is located at a lower position, so that the first connecting plate portion 12 and the second connecting plate portion 13 form a high and low setting structure, thereby making the tube pressing device 1 have a differentiated setting structure with different heights at both ends.

[0034] In this way, when the pipe crimper 1 is fixed to a fixed foundation such as a mounting bracket, the first connecting plate portion 12 and the second connecting plate portion 13 have different structures at the connection portion corresponding to the fixed foundation; only in a specific installation posture can the first connecting plate portion 12 and the second connecting plate portion 13 be connected and fixed on the fixed foundation, and the pipe crimper 1 and the fixed foundation can thus be fixedly connected, so the first connecting plate portion 12 and the second connecting plate portion 13 are easy to quickly and accurately align on the fixed foundation, thereby avoiding the problem of installation misalignment. Compared with the related art, the pipe crimper 1 provided in the embodiment of the present application can quickly and accurately realize pipeline fixation, thereby reducing the labor burden and improving the efficiency of installation and fixation.

[0035] The structure of the tube pressing plate body 11 can be determined according to actual needs, and the embodiments of the present application do not limit this. In some embodiments, the tube pressing plate body 11 can have a first flat plate portion 111, an arc-shaped plate portion 112, and a second flat plate portion 113 arranged in sequence, and the first flat plate portion 111, the arc-shaped plate portion 112, and the second flat plate portion 113 can be enclosed to form a through groove cavity. Here, the end of the first flat plate portion 111 away from the arc-shaped plate portion 112 can be connected to the first connecting plate portion 12, and the end of the second flat plate portion 113 away from the arc-shaped plate portion 112 can be connected to the second connecting plate portion 13.

[0036] In some examples, the arc-shaped plate portion 112 may have a semicircular structure. In some examples, the first flat plate portion 111 and the second flat plate portion 113 may be arranged in parallel, and the extension length of the first flat plate portion 111 is less than the extension length of the second flat plate portion 113; that is, the second flat plate portion 113 extends to the side of the plane where the first connecting plate portion 12 is located away from the arc-shaped plate portion 112. In this way, it is possible to ensure that the height position between the first connecting plate portion 12 and the second connecting plate portion 13 has a different arrangement structure.

[0037] The connection and fixing method between the first connecting plate portion 12 / the second connecting plate portion 13 and the fixed base can be determined according to actual needs, and can adopt connection and fixing methods such as bolt connection, pin connection, and clamping, etc., which are not limited in the embodiments of the present application. In some embodiments, the first connecting plate portion 12 can be provided with a connecting through hole 121, and fasteners such as bolts and pins can pass through the connecting through hole 121 and be fastened to the fixing hole 31 on the fixed base, and the second connecting plate portion 13 can be suitable for clamping with the clamping groove 32 on the fixed base.

[0038] When fixing the pipe crimper 1 on the fixed base, the installer can firstly clamp the second connecting plate portion 13 and the clamping groove 32 on the fixed base, and then align the connecting through hole 121 on the first connecting plate portion 12 and the fixing hole 31 on the fixed base, and connect and fix them by fasteners. Since the structural differences between the first connecting plate portion 12 and the second connecting plate portion 13, the fixing hole 31 and the clamping groove 32 are relatively obvious, the installer can quickly determine the correspondence between the first connecting plate portion 12 / the second connecting plate portion 13 and the fixing hole 31 / the clamping groove 32, and then quickly and accurately realize the alignment installation of the pipe crimper 1 on the fixed base, effectively avoiding the problem of installation misalignment, thereby reducing the labor burden and improving the installation and fixing efficiency.

[0039] like Figures 1 to 4 As shown, in the second aspect, an embodiment of the present application provides a pipeline structure, which includes a connecting pipeline 2, a pipeline support 3 and a pipe pressing device 1 provided in any of the above embodiments. The first connecting plate portion 12 and the second connecting plate portion 13 are respectively connected and fixed to the pipeline support 3, and the pipe pressing plate body 11 and the pipeline support 3 enclose a pipe cavity, and the connecting pipeline 2 is arranged by passing through the pipe cavity. The pipeline structure has the above-mentioned pipe pressing device 1, so that the pipeline can be fixed quickly and accurately, thereby reducing the labor burden and improving the installation and fixing efficiency.

[0040] In some embodiments, the pipe support 3 may be provided with a fixing hole 31 and a card slot 32. Here, the first connecting plate portion 12 may be provided with a connecting through hole 121, and fasteners such as bolts and pins may be passed through the connecting through hole 121 and connected and fastened with the fixing hole 31, and the second connecting plate portion 13 may be clamped in the card slot 32. Since the structural differences between the first connecting plate portion 12 and the second connecting plate portion 13, the fixing hole 31 and the card slot 32 are relatively obvious, the installer can quickly and accurately align the first connecting plate portion 12 and the fixing hole 31, and the second connecting plate portion 13 and the card slot 32, respectively, and then quickly and accurately realize the alignment installation of the pipe crimper 1 on the fixed base, effectively avoiding the problem of installation misalignment, thereby reducing the labor burden and improving the installation and fixing efficiency.

[0041] The structure of the connecting pipeline 2 can be determined according to actual needs, and this embodiment of the present application does not limit this. Figure 5 As shown, in some embodiments, the connecting pipeline 2 may include a return pipe 21 and an exhaust pipe 22. The return pipe 21 is configured to be connected to the suction end of the compressor 4, and the end of the return pipe 21 away from the compressor 4 may be connected to the evaporator; the exhaust pipe 22 is configured to be connected to the exhaust end of the compressor 4, and the end of the exhaust pipe 22 away from the compressor 4 may be connected to the condenser 5.

[0042] Here, a bend section may be provided at one end of the return air pipe 21 and / or the exhaust pipe 22 adjacent to the compressor 4. In some examples, a bend section, i.e., a first bend section 211, is provided at one end of the return air pipe 21 adjacent to the compressor 4, while no bend section is provided at one end of the exhaust pipe 22 adjacent to the compressor 4. In other examples, a bend section, i.e., a second bend section 212, is provided at one end of the exhaust pipe 22 adjacent to the compressor 4, while no bend section is provided at one end of the return air pipe 21 adjacent to the compressor 4. In still other examples, a bend section, i.e., a first bend section 211, is provided at one end of the return air pipe 21 adjacent to the compressor 4, and a bend section, i.e., a second bend section 212, is also provided at one end of the exhaust pipe 22 adjacent to the compressor 4. Here, the above-mentioned bend section may be directly connected to the intake end / exhaust end of the compressor 4.

[0043] Here, the curved pipe section has a curved pipe structure and can form a planar shock-absorbing structure. On the one hand, the curved pipe structure can increase the damping of the fluid flowing therein and reduce the kinetic energy of the fluid, thereby achieving the purpose of reducing dynamic vibration; on the other hand, the curved pipe structure can increase the stiffness and vibration resistance of the return air pipe 21 and reduce the vibration caused by the impact of fluids such as gaseous refrigerants. Here, the structural form of the curved pipe structure of the curved pipe section can be determined according to actual needs, and can adopt types such as U-shaped, serpentine, spiral, etc., which are not limited in the embodiments of the present application.

[0044] In some examples, a first curved pipe section 211 may be provided at one end of the return pipe 21 adjacent to the compressor 4, and a second curved pipe section 212 may also be provided at one end of the exhaust pipe 22 adjacent to the compressor 4; here, the plane where the first curved pipe section 211 is located and the plane where the second curved pipe section 212 is located may be vertically or angled. Based on the above vertical or angled setting relationship, two planar shock absorbing structures with vertical or angled inclinations may be provided, thereby increasing the stiffness of the connecting pipe 2 in multiple directions, thereby achieving a vibration reduction effect in multiple directions.

[0045] like Figure 5 and Figure 6As shown, in some examples, the plane where the bend section is located can be parallel or perpendicular to the tangent of the rotating circle of the compressor 4. Here, the tangent of the rotating circle of the compressor 4 is perpendicular to a characteristic plane, the characteristic plane is perpendicular to the plane where the bend section is located, and the rotation center axis of the compressor 4 is located on the characteristic plane. In this way, the force direction of the end of the return pipe 21 / exhaust pipe 22 adjacent to the compressor 4 is consistent or substantially consistent with the running direction of the compressor 4, which can reduce the impact of the vibration of the compressor 4 on the pipeline section, thereby reducing the risk of forced damage to the pipeline, thereby improving the reliability and stability of the connecting pipeline 2.

[0046] In some examples, the plane where the bend section is located can be parallel to the central axis of rotation of the compressor 4. By setting as above, it can be better ensured that the force direction of one end of the return air pipe 21 / exhaust pipe 22 adjacent to the compressor 4 is consistent or basically consistent with the running direction of the compressor 4, thereby reducing the influence of the vibration of the compressor 4 on the pipe section. Exemplarily, the plane where the bend section is located can be parallel or perpendicular to the tangent of the rotation circle of the compressor 4, and the plane where the bend section is located can be parallel to the central axis of rotation of the compressor 4, which can better ensure that the force direction of one end of the return air pipe 21 / exhaust pipe 22 adjacent to the compressor 4 is consistent or basically consistent with the running direction of the compressor 4, thereby reducing the influence of the vibration of the compressor 4 on the pipe section.

[0047] In some examples, the connecting pipeline 2 may include an evacuation and charging needle valve 23, which is disposed on the return air pipe 21. During the production stage of the equipment where the pipeline structure is located, the evacuation and charging needle valve 23 may be used to evacuate the air in the connecting pipeline 2 and to fill the connecting pipeline 2 with refrigerant; and during the operation stage of the equipment where the pipeline structure is located, the evacuation and charging needle valve 23 may be used to fill and supplement the connecting pipeline 2 with refrigerant.

[0048] like Figure 7 As shown, in some examples, the connecting pipeline 2 includes an evacuation process branch pipe 24, one end of which is connected to the pipe section of the exhaust pipe 22 close to the condenser 5, and the other end is blocked after the evacuation process is completed. During the production stage of the equipment where the pipeline structure is located, the evacuation process branch pipe 24 can be used to quickly evacuate the air in the connecting pipeline 2; and after the evacuation process is completed, the end of the evacuation process branch pipe 24 away from the exhaust pipe 22 can be blocked by plugging, welding sealing, etc. to avoid refrigerant leakage.

[0049] like Figures 1 to 7As shown, in the third aspect, an embodiment of the present application provides an air conditioner, which includes a compressor 4, a condenser 5, an evaporator, a throttle and a pipeline structure provided by any of the above embodiments, and the compressor 4, the condenser 5, the evaporator and the throttle are connected through the above-mentioned connecting pipeline 2. The type of air conditioner can be determined according to actual needs, and can be, for example, a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, an energy storage air conditioner, etc., which is not limited in the embodiment of the present application. The air conditioner has the above-mentioned pipeline structure, so that the pipeline can be fixed quickly and accurately, thereby reducing the labor burden and improving the installation and fixing efficiency.

[0050] In some embodiments, the compressor 4 may be configured with an integrally arranged liquid storage tank 41 . Here, the return air pipe 21 may be connected to the liquid storage tank 41 .

[0051] The pipe squeezer, pipeline structure and air conditioner provided in the embodiments of the present application are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. At the same time, for those skilled in the art, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as limiting the present application.
