DETAILED DESCRIPTION

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The terms "comprising" and "having," and any variations thereof, in the specification, claims, and drawings of this application are intended to cover without excluding other terms. The words "a" or "an" do not exclude the presence of multiples. Unless otherwise stated, "multiple" means two or more (including two), and similarly, "multiple sets" means two or more (including two sets).

[0023] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this application. For example, in the description of this application, terms such as "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0024] Furthermore, the descriptions of directions such as the X direction, Y direction, and Z direction used to explain the operation and construction of the components in this embodiment are not absolute but relative. Although these directions are appropriate when the components are in the positions shown in the figure, they should be interpreted differently when these positions change to correspond to the changes.

[0025] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, "connection" or "linkage" in mechanical structures can refer to a physical connection, such as a fixed connection, a detachable connection, or an integral connection. In addition to referring to a physical connection, "connection" or "linkage" in circuit structures can also refer to an electrical connection or a signal connection. For example, it can be a direct connection, i.e., a physical connection, or an indirect connection through at least one intermediate component, as long as the circuit is connected. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0027] This application provides a compressor pipeline connection structure, including a connection compartment 1: a first pipe 2 is fixedly connected to the side wall of the connection compartment 1, and a second pipe 3 is provided inside the connection compartment 1. A positioning ring 4 is fixedly connected to the outer wall of the second pipe 3. A pair of limiting grooves 5 are provided on the side wall of the connection compartment 1, and a limiting block 6 is provided inside the limiting groove 5. The pair of limiting blocks 6 are fixedly connected to the side wall of the positioning ring 4. A locking block 7 passes through the side wall of the pair of limiting grooves 5. A transmission block 8 is fixedly connected to the side wall of the pair of locking blocks 7 that are far apart. L-shaped blocks 9 are fixedly connected to the two side walls of the connection compartment 1. A spring 10 is fixedly connected between the inner wall of the transmission block 8 and the L-shaped block 9. A locking groove 11 matching the locking block 7 is provided on the side wall of the pair of limiting blocks 6.

[0028] In the technical solution of this application embodiment, the L-shaped block 9 is covered by the cover shell 12 to prevent the L-shaped block 9 from being pushed accidentally. The cover shell 12 is fitted on the L-shaped block 9. The top and bottom of the connecting chamber 1 are provided with annular grooves 13 that match the cover shell 12. The sealing performance between the positioning ring 4 and the connecting chamber 1 is improved by the sealing rubber ring 14. The inner wall of the positioning ring 4 is provided with the sealing rubber ring 14.

[0029] In the technical solution of this application embodiment, the sealing performance between the second pipe 3 and the connecting chamber 1 is improved by the sealing tube 15. The second pipe 3 is provided with the sealing tube 15, which is fixedly connected to the inner wall of the connecting chamber 1. Anti-slip texture is provided on the outer wall of a pair of cover shells 12, and a pair of limiting blocks 6 are symmetrically arranged about the central axis of the positioning ring 4.

[0030] Working principle: In use, the second pipe 3 is inserted into the connecting chamber 1, and the limiting block 6 is inserted into the limiting groove 5. Then, the inclined surface of the limiting block 6 pushes the locking block 7 to move until the locking block 7 moves to one side of the slot 11. The spring 10 pulls the transmission block 8 to move, and the transmission block 8 drives the locking block 7 to move until the locking block 7 is inserted into the slot 11, thereby fixing the positioning ring 4 and the second pipe 3. Then, the cover shell 12 is put on the L-shaped block 9 and inserted into the annular groove 13 to prevent the transmission block 8 from being pushed accidentally. During the use of the second pipe 3, the sealing rubber ring 14 improves the sealing between the positioning ring 4 and the connecting chamber 1, and the sealing tube 15 improves the sealing between the second pipe 3 and the connecting chamber 1, thereby improving the connection sealing between the first pipe 2 and the second pipe 3. When it is necessary to disassemble the second pipe 3, pull out the cover shell 12, pull the transmission block 8, and the transmission block 8 drives the locking block 7 to disengage from the slot 11, thereby pulling out the second pipe 3.
