Description

Technical Field

[0001] The utility model relates to the technical field of air compressor accessories, in particular to a high-temperature resistant metal hose for an air compressor with a protective structure. Background Art

[0002] Metal hoses are very important accessories in air compressors. Most of the lines inside air compressors are installed in metal hoses to protect the lines and prevent them from high temperature corrosion.

[0003] Most of the metal hoses inside existing air compressors are installed directly. Although the metal hoses can protect the lines, the metal hoses themselves lack corresponding protective structures, which causes the outer peripheral side of the metal hoses to be easily corroded when the air compressor is working, affecting the normal use of the air compressor. Therefore, an air compressor high-temperature resistant metal hose with a protective structure is needed to solve the above-mentioned problems. Utility Model Content

[0006] As a further solution of the utility model: the telescopic structure includes a groove, a telescopic rod and a spring, there are multiple grooves and they are symmetrically opened on the side surfaces of each group of semicircular rings close to each other, the telescopic rod is arranged between two symmetrical grooves, the top end of the telescopic rod is fixedly connected to the top of the inner wall of the groove located above, the bottom end of the telescopic rod is fixedly connected to the bottom of the inner wall of the groove located below, the spring is movably sleeved on the surface of the telescopic rod, the top end of the spring is fixedly connected to the top of the inner wall of the groove located above, and the bottom end of the spring is fixedly connected to the bottom of the inner wall of the groove located below.

[0007] As a further solution of the utility model: when the spring is not subjected to external force, the semicircular ring is just sleeved on the surface of the mounting ring.

[0008] As a further solution of the utility model: slots are provided on the top surface and the bottom surface of the installation ring, and plugs that can be inserted into the corresponding slots are fixedly connected to the inner walls of each of the two semicircular rings.

[0009] As a further solution of the utility model: a pull ring is fixedly connected to the middle part of the outer wall of each semicircular ring.

[0010] By adopting the above technical solution, compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model provides a plastic tube which is sleeved on the metal hose. The plastic tube can provide all-round protection for the outer peripheral side of the metal hose, and the retractable semicircular ring can make the plastic tube more convenient to disassemble. The specific operation is to insert the metal hose body into the plastic tube, pull apart each group of semicircular rings, and then sleeve the two groups of semicircular rings on the surfaces of two mounting rings respectively.
