Description

Technical Field

[0001] This utility model relates to the field of compressor pipeline connector technology, and in particular to a compressor connection structure that facilitates interface docking. Background Technology

[0002] In compressor systems, the reliability and ease of piping connection directly affect the operating efficiency and safety of the equipment.

[0003] Traditional compressor piping connection methods mainly include welding, flange connection, and threaded connection. Although welding provides a strong connection, the operation requires specialized equipment and technicians, and disassembly is difficult during later maintenance, which can easily damage the piping. Flange connection relies on a large number of bolts for fastening, the installation process is cumbersome and time-consuming, and there is a risk of reduced sealing performance due to loose bolts. Utility Model Content

[0004] The purpose of this invention is to provide a compressor connection structure that facilitates interface docking, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution, which includes a connecting body, wherein a plurality of mounting slots are provided on the connecting body, and an anti-retraction component is provided in each mounting slot, and a pair of top-pressure nuts are symmetrically arranged on the connecting body.

[0006] As a preferred embodiment of this utility model, the connecting body includes a connecting pipe, and abutment rings are symmetrically arranged on both sides of the inner wall of the connecting pipe. A sealing ring is provided on the outer wall of each abutment ring. A ring of clamping flaps is provided on both sides of the connecting pipe. Anti-slip teeth are provided on the inner wall of each clamping flap. Several clamping flaps are conical.

[0007] As a preferred embodiment of the present invention, the anti-retraction component includes a lifting spring disposed in the mounting groove, a stop block disposed at the top of the lifting spring, and an anti-detachment plate disposed at the bottom front end of the stop block.

[0008] As a preferred embodiment of this utility model, a baffle is provided on the opening of each mounting slot, and the baffle is located directly above the anti-detachment plate.

[0009] As a preferred embodiment of this utility model, spiral patterns are symmetrically arranged on the outer walls of both sides of the connecting pipe, and the two top-pressing nuts are respectively spirally arranged on the two spiral patterns.

[0010] As a preferred embodiment of this utility model, the outer wall of the top-pressure nut is provided with anti-slip texture.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: When using this utility model, simply insert the pipe into the connecting pipe and manually tighten the top nut to simultaneously complete the clamping and fixing. A single person can operate it in just a few minutes, which greatly shortens the installation time compared to the traditional method. When disassembling, press the stop block to loosen the nut in the opposite direction, avoiding the high costs and safety hazards caused by repeated disassembly and assembly of bolts or welding, significantly improving maintenance efficiency and reducing manpower and equipment wear and tear.

[0012] This utility model uses a mechanical limiting structure consisting of a stop block and a lifting spring. After the top-pressing nut is in place, it automatically pops out to form a rigid block. Even in extreme environments where the compressor vibrates at high frequency and the temperature changes cause the material to expand and contract, it can still physically limit the rotation of the nut, effectively avoiding safety accidents such as pipe detachment and leakage caused by loose nuts.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0016] like Figure 1-4 As shown, the present invention proposes a compressor connection structure that facilitates interface docking. It includes core components such as a connection body 1, an anti-loosening component 2, and a top pressure nut 3. The components work together to achieve quick connection and anti-loosening function of the pipeline. The connecting body 1 is composed of a connecting pipe 10, which is a hollow cylindrical structure. Its interior serves as a channel for pipe connection. Abutment rings 11 are symmetrically arranged on both sides of the inner wall of the connecting pipe 10, and a sealing ring 12 is fitted on its outer wall. The sealing ring 12 is made of high elastic silicone material and is tightly fitted to the outer wall of the abutment ring 11 by interference fit. When the compressor delivery pipe and the equipment delivery pipe are inserted into both ends of the connecting pipe 10, the pipe port can be tightly abutted with the sealing ring 12 to form a sealing barrier and effectively prevent fluid leakage. A ring of clamping petals 13 is provided on both sides of the connecting pipe 10, which are evenly distributed in a cone shape at the port. Each clamping petal 13 has anti-slip teeth on its inner wall. Spiral patterns 15 are symmetrically machined on the outer walls of both sides of the connecting pipe 10. Two top-pressure nuts 3 are respectively connected to the two spiral patterns 15 by threads. Anti-slip patterns 30 are provided on the outer wall of the top-pressure nuts 3, which makes it easy for operators to tighten the nuts by hand and improves the convenience of operation. Several mounting slots 14 are provided on the wall of the connecting pipe 10. Each mounting slot 14 is provided with an anti-retraction component 2. The anti-retraction component 2 includes a lifting spring 20 and a stop block 21. The lifting spring 20 is vertically installed at the bottom of the mounting slot 14 and has a certain pre-compression amount, which can provide an upward lifting force for the stop block 21. An anti-detachment plate 22 is integrally formed at the front end of its bottom. The width of the anti-detachment plate 22 is greater than the width of the slot opening of the mounting slot 14, which is used to prevent the stop block 21 from completely detaching from the mounting slot 14. A baffle 16 is fixedly installed at the slot opening of each mounting slot 14. The baffle 16 is located directly above the anti-detachment plate 22, which can limit the maximum upward movement of the stop block 21 and at the same time protect the anti-retraction component 2 from dust and foreign object intrusion.

[0017] First, insert the compressor's delivery pipe and the equipment's delivery pipe ports into the two ends of the connecting pipe 10 respectively, ensuring that the pipe ports are tightly abutted against the sealing ring 12 inside the connecting pipe 10. The sealing ring 12 is made of elastic silicone material, and forms an initial seal when the pipe is inserted through an interference fit, providing a basic leak-proof guarantee for subsequent connections. Subsequently, manually turn the top pressure nut 3 clockwise along the spiral 15. The top pressure nut 3 moves forward by means of the thread transmission principle. When the front end of the top pressure nut 3 contacts several clamping plates 13, radial pressure is applied to the clamping plates 13 through the inner surface, causing the clamping plates 13 to retract inward at the same time, tightly clamping and fixing the inserted delivery pipe. The inner side of the clamping plates 13 is provided with anti-slip teeth, which can increase the friction with the outer wall of the pipe and ensure a stable connection. After the top-pressure nut 3 continues to move forward and exceeds several mounting slots 14 on the connecting pipe 10, the stop block 21 hidden in the mounting slot 14 pops out of the slot under the action of the lifting spring 20. The stop block 21 mechanically limits the movement in the counterclockwise direction, making it difficult to loosen, thus achieving the anti-loosening function. If disassembly is required, simply use a tool to press the stop block 21 back into the mounting slot 14, and the top-pressure nut 3 can be unscrewed smoothly to complete the pipe separation. The whole process is convenient to operate and takes into account both the needs of quick connection and reliable anti-loosening.
