Description

Technical Field

[0001] This utility model relates to the field of laboratory piping installation technology, and in particular to a quick-installation interface structure for laboratory piping systems. Background Technology

[0002] Laboratories are core locations for scientific research, teaching, and industrial innovation, and their design and management must balance safety, functionality, flexibility, and sustainability. The installation of piping systems is a crucial component of laboratories, used to transport waste gases and liquids generated within them.

[0003] In existing technologies, pipes need to be connected using appropriate connectors during installation. However, the existing interface structures are inconvenient to install and disassemble, inefficient, and not conducive to later maintenance.

[0004] Therefore, we propose a quick-installation interface structure for laboratory piping systems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as inconvenient installation and disassembly of interface structures, low efficiency, and difficulty in later maintenance, and to propose a quick-install interface structure for laboratory piping systems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-install interface structure for a laboratory piping system includes:

[0008] A connecting pipe, wherein multiple annularly distributed conical clamping blocks are fixed at both ends of the connecting pipe, and the outer circumferential surface of the clamping blocks is provided with external threads;

[0009] Two connecting sleeves are fitted onto the outer wall of the connecting pipe, and the inner wall of the connecting sleeves is provided with internal threads that mate with the threaded clamping block.

[0010] An adjusting sleeve is rotatably connected to the outer wall of the connecting pipe, and the inner wall of the adjusting sleeve is provided with internal threads;

[0011] Two sliding sleeves are slidably connected to the outer wall of the connecting pipe. The outer wall of each sliding sleeve has an external thread that mates with the thread of the adjusting sleeve, and symmetrically arranged positioning grooves are formed on the outer wall of each sliding sleeve.

[0012] The protective mechanism includes a first connecting shell and a second connecting shell that are detachably sleeved on the outside of the connecting pipe. The inner walls of the first connecting shell and the second connecting shell are fixedly provided with insert plates that are inserted into the positioning groove.

[0013] The connecting sleeve is rotated to drive the clamping block to retract radially to clamp the pipe, the adjusting sleeve is rotated to drive the sliding sleeve to move axially to abut against the connecting sleeve, and the insert plate cooperates with the positioning groove to restrict the sliding sleeve from retracting.

[0014] As a further improvement to the above technical solution:

[0015] The first connecting shell has buckles on both sides, and the second connecting shell has annular blocks on both sides that engage with the buckles. The inner walls of both ends of the connecting tube have mounting grooves. One inner wall of the mounting groove has a first sealing ring, and the inner wall of the circumference has a second sealing ring. The inner wall of the sliding sleeve has a sliding groove. The outer wall of the connecting tube is fixed with a slider that slides in cooperation with the sliding groove. The inner walls of both sides of the positioning groove have rubber plates that are in interference contact with the insert plate. The outer walls of both the connecting sleeve and the adjusting sleeve have anti-slip grooves. The taper angle of the clamping block is 5°-15°. The first sealing ring is made of fluororubber, and the second sealing ring is made of silicone rubber. The mating surface between the buckle and the annular block has an elastic damping layer. The end of the insert plate is wedge-shaped, and the gap between it and the opening of the positioning groove is less than 0.5mm.

[0016] In this application, during assembly, one end of the connecting pipe is inserted into the mounting groove, causing one end of the connecting pipe to abut against the first sealing ring, and the outer wall of the connecting pipe to abut against the second sealing ring. Then, the connecting sleeve is rotated using a tool, causing the connecting sleeve and the clamping block to be threaded together. Due to the different thicknesses on both sides of the clamping block, the clamping block can be contracted to clamp and fix the connecting pipe. Then, the adjusting sleeve is rotated using a tool. Guided by the slider and the slide groove, the adjusting sleeve drives the sliding sleeve to move along the direction of the slide groove, causing the sliding sleeve to abut against the connecting sleeve for initial positioning to prevent the connecting sleeve from loosening. Then, the insert plate and the positioning groove are aligned, and the first connecting shell and the second connecting shell are fitted onto the outside of the connecting pipe, so that the buckle and the annular block align. The first connecting shell and the second connecting shell provide protection for the connecting pipe and related structures. At the same time, the insert plate can limit the sliding sleeve to prevent it from sliding, and then limit the connecting sleeve again to achieve a double limiting effect, preventing the sliding sleeve from loosening and ensuring the stability of the overall structure.

[0017] Beneficial effects: In this utility model, the quick-installation interface structure of the laboratory piping system, through the setting of multiple structures such as connecting sleeve, adjusting sleeve and sliding sleeve, allows people to quickly assemble and disassemble the pipes, making the operation simple and convenient and improving work efficiency.

[0018] In this utility model, the quick-installation interface structure of the laboratory piping system, through the setting of multiple structures such as adjusting sleeve, sliding sleeve and insert plate, can double limit the connection sleeve, ensuring the stability of the structure and preventing the structure from loosening;

[0019] In this utility model, the quick-install interface structure of the laboratory piping system, through the setting of multiple structures such as the first connecting shell, the second connecting shell and the insert plate, can provide protection for the connecting pipe and related structures, and avoid them from being impacted by external forces.

[0020] This invention allows for quick and easy assembly and disassembly of pipes, simplifying operation and improving work efficiency. It also provides double-limiting for the connecting sleeve, ensuring structural stability and preventing loosening. Furthermore, it protects the connecting pipe and related structures from external impacts. Attached Figure Description
