[0030] In order to make the purpose, technical scheme and advantage of the utility model embodiment clearer, the following will combine the drawings in the utility model embodiment, and clearly and completely describe the technical scheme in the utility model embodiment. The described embodiment is a part of the embodiment of the utility model, not all the embodiments.

[0031] Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the utility model.

[0032] Embodiment 1

[0033] With reference to Figures 1 to 4 The spring mounting assembly provided by the embodiment comprises a core body 1 and a sleeve 2 sleeved outside the core body 1, the core body 1 is movably connected with the sleeve 2, and the core body 1 can move back and forth in the sleeve 2.

[0034] A first opening 21 is formed in the side wall of the sleeve 2, and the first opening 21 is used for allowing the spring to enter the inside of the sleeve 2. The core body 1 comprises a first end portion 11 located inside the sleeve 2 and a second end portion 12 located outside the sleeve 2, and the first end portion 11 is provided with a pressing piece 13 used for abutting against the spring located inside the sleeve 2. As shown in Figure 2 and Figure 3 A spring mounting hole B is formed in the outer side wall of the cylinder body A, a vane C is inserted into the inner side wall of the cylinder body A, the position of the vane C corresponds to the position of the spring mounting hole B, a spring D is mounted in the spring mounting hole B, one end of the spring D is in interference connection with the inner wall of the spring mounting hole B, and the other end of the spring D abuts against the vane C. When the spring D is mounted, the sleeve 2 is aligned with the spring mounting hole B, the spring D is put into the inside of the sleeve 2 from the first opening 21, the second end portion 12 of the core body 1 is pushed by an external force, the first end portion 11 is urged to push the spring D forward, and finally the spring D is pressed into the spring mounting hole B, thereby completing the mounting of the spring D.

[0035] The spring mounting process is convenient to operate and has high installation efficiency, and the linear pushing of the first end portion 11 is not easy to generate a torsional force on the spring during the installation process, thereby reducing the risk of fracture of the spring during the installation process, reducing the reliability risk of the spring, and being beneficial to prolonging the service life of the compressor. Meanwhile, the spring mounting assembly has a simple structure and low production cost.

[0036] In some embodiments, the pushing force can be applied to the second end portion 12 by manual operation; in other embodiments, the pushing force can also be applied to the second end portion 12 by a driving cylinder or a driving motor.

[0037] In some embodiments, the pressing piece 13 comprises a plurality of pressing structures 131 uniformly distributed around the axis of the core body 1, the side wall of the sleeve 2 is provided with a through groove 22 corresponding to the position of the pressing structure 131, and the pressing structure 131 is inserted into the through groove 22. It can be understood that the plurality of pressing structures 131 are distributed around the axis of the core body 1 in a flower shape, and the pressing structure 131 protrudes from the side wall of the core body 1 and can be exposed outside the sleeve 2 through the through groove 22. It should be noted that in some embodiments, the first opening 21 and the through groove 22 can partially overlap, but this will not affect the normal use of the spring mounting assembly.

[0038] Since the spring is placed inside the sleeve 2 and moves inside the sleeve 2, which means that the diameter of the spring is smaller than the diameter of the sleeve 2, and the abutting structure 131 can be exposed outside the sleeve 2 through the through slot 22, which means that the size of the abutting structure 13 is larger than the size of the spring, so that it can ensure that there is a large enough contact area between the abutting structure 13 and the spring during the process of pushing the spring forward, effectively preventing the spring from being deflected or tilted during movement, thereby improving the stability of the spring during movement, and facilitating the improvement of the installation efficiency and quality of the spring.

[0039] As a further optimization, a guide inclined portion 1311 is formed at the position of the abutting structure 131 abutting against the spring. By providing the guide inclined portion 1311, when the spring is pushed into the spring mounting hole and the pushing force continues to be applied to the second end portion 12, the end of the spring abutting against the abutting structure 131 will move along the guide inclined portion 1311 and be deformed and expanded, thereby causing the spring to further interfere with the inner wall of the spring mounting hole, making the spring more stably connected to the spring mounting hole, and facilitating the improvement of the installation stability and firmness of the spring, thereby prolonging the service life of the compressor.

[0040] In the present embodiment, the number of abutting structures 131 is three, and the three abutting structures 131 are distributed in a triangular manner. In this way, it is not only beneficial to improve the abutting stability between the abutting structure 131 and the spring and ensure the installation quality, but also can control the production cost and improve the production benefit.

[0041] The spring mounting assembly of the present embodiment completes the installation of the spring through the cooperation of the core and the sleeve, effectively improving the installation efficiency of the spring, thereby improving the production efficiency, and reducing the reliability risk of the spring during installation, which is beneficial to prolong the service life of the compressor. At the same time, the overall structure of the spring mounting assembly is simple, and the production cost is low; by penetrating the abutting structure into the through slot, the stability of the spring during movement can be improved, and the installation efficiency and quality of the spring can be improved; by providing the guide inclined portion, the connection stability between the spring and the spring mounting hole can be improved, which is beneficial to prolong the service life of the compressor.

[0042] Embodiment 2

[0043] As a further optimization of embodiment 1, referring to Figures 5 to 6 , the sleeve 2 is provided with a second opening 23 and a third opening 24 at opposite ends, respectively, the second opening 23 abuts against the spring mounting hole, and the core 1 penetrates the third opening 24. During spring installation, the core 1 is pushed by external force to push the spring through the second opening 23 and into the spring mounting hole.

[0044] As a further optimization, the second opening 23 is formed with a guide protrusion 231 extending outward along the length direction of the sleeve 2, and the guide protrusion 231 is configured to extend into the interior of the spring mounting hole. It should be noted that the guide protrusion 231 is formed by extending the inner edge of the second opening 23 outward along the length direction of the sleeve 2, so that the outer edge of the second opening 23 can abut against the outside of the spring mounting hole, and the guide protrusion 231 can extend into the interior of the spring mounting hole. The guide protrusion 231 can guide the spring into the spring mounting hole, which is conducive to improving the spring mounting efficiency. Moreover, the position where the guide protrusion 231 extends into does not reach the position where the spring is connected to the spring mounting hole in an interference fit, so it will not interfere with the connection between the spring and the spring mounting hole, and the installation quality can be ensured.

[0045] In some embodiments, the second end portion 12 is provided with a pushing piece 14 configured to abut against the third opening 24. On the one hand, the provision of the pushing piece 14 can facilitate manual operation and improve the spring mounting efficiency. On the other hand, by abutting the pushing piece 14 against the third opening 24, the pushing depth of the core 1 can be limited, so that the core 1 is prevented from being pushed in too deeply and damaging the spring, and the installation quality and production quality can be ensured.

[0046] In some embodiments, the core 1, the abutting piece 13, and the pushing piece 14 can be integrally formed or can be separate structures.

Through the cooperation of the first guide structure 15 and the second guide structure 25, the core 1 can move linearly in a direction without rotating and deviating inside the sleeve 2, so that the core 1 will not generate a torsional force on the spring during the spring mounting process, the installation quality of the spring is improved, the reliability risk of the spring is further reduced, and the service life of the compressor is prolonged.

[0049] As one of the embodiments, the first guide structure 15 is a strip-shaped guide groove, and the second guide structure 25 is a strip-shaped protrusion, and the strip-shaped protrusion is slidingly connected in the strip-shaped guide groove. Through the cooperation of the strip-shaped protrusion and the strip-shaped guide groove, it can be ensured that the strip-shaped protrusion slides in the strip-shaped guide groove during the entire spring mounting process, so that the core 1 moves linearly in a direction during the entire spring mounting process, which is conducive to further ensuring the installation quality.

[0050] In the embodiment, the number of the first guide structures 15 is three, the three first guide structures 15 are in triangular distribution, and the number and distribution of the second guide structures 25 are matched with those of the first guide structures 15. Thus, the cooperation stability between the first guide structures 15 and the second guide structures 25 is improved, the stability of the spring mounting process is improved, and the mounting quality and the production quality are improved.
