Hose clamping device

Abstract

The invention relates to a hose clamping device, comprising a hose joint. The clamping device is characterized in that: the clamping device also comprises an inner cone nut and a pipe bolt matched with each other; a big-aperture end of the inner cone nut is a screw-in end, and a small-aperture end corresponding to the big-aperture end is the tail end of the inner cone nut; an inner thread of the inner cone nut is a tapered thread; the thread small diameter A of the tail end of the inner cone nut is slightly more than the outer diameter of a hose; more than two strip openings parallel to a central shaft are uniformly distributed at a threaded end of the pipe bolt in the circumferential direction of a pipe wall; the inner diameter C of a central hole of the pipe bolt is slightly more than the outer diameter of the hose. The clamping device is safe, practical, simple in structure, good in service performance, excellent in economic benefit and extensive in application, can be made of metal material or nonmetal material, can be widely used in all aspects of production, life, industry and agriculture, and can produce good economic benefit and social benefit.

Description

technical field [0001] The invention relates to a hose clamp, in particular to a hose clamping device. Background technique [0002] As we all know, regardless of vehicles, equipment or daily life, whether it is used to transport liquid or gas, whether it is used under normal pressure or under high pressure, the use of hose clamping devices abounds, with a large amount of use and a wide range of applications The vastness is self-evident. And the existing hose clamping device, the structure is simple and crude, such as the connection at the household gas pipeline interface is tightened with a metal wire, and the compressed gas output hoses such as the nozzles used for cleaning on the factory site or the anti-aircraft spray guns are clamped with U-shaped clamp screws. , to varying degrees, there are problems such as inconvenient loading and unloading, poor sealing safety performance, sharp corners and corners that are easy to scratch personnel or damage hoses; the structure i...

Problems solved by technology

And the existing hose clamping device, the structure is simple and crude, such as the connection at the household gas pipeline interface is tightened with a metal wire, and the compressed gas output hoses such as the nozzles used for cleaning on the factory site or the anti-aircraft spray guns are clamped with U-shaped clamp screws. , to varying degrees, there are problems such as inconvenient loading and unloading, poor sealing safety performance, sharp corners and corners that are easy to scratch personnel or damage hoses; the structure is complex

As disclosed in PCT patent application 02825291.8 (publication number CN1605005A), see Fig. 1, Fig. 2, and as described in application number 01802897.7 (publication number CN1420975A, authorized announcement number CN1187550C), see image 3 , Figure 4 On the one hand, its structure is complicated, usually it must be made of all metal, and the processing cost is high. On the other hand, special tools are required for its installation or disassembly, which is troublesome and unsightly. If the hose is hard, it is difficult to install; at the same time, The above two structures also have the problem of insufficient clamping force for high-pressure pipes with high internal pressure.

Scratch-prone when used on fuel guns such as gas stations or construction sites
