Abstract
The utility model relates to a low pressure hose larynx hoop, including the strap, strap one end is first connecting portion, the strap other end is the second connecting portion, and open the second connecting portion has the rectangle through-hole, first connecting portion width is less than the through-hole width, and first connecting portion pass the through-hole, larynx hoop internal diameter is less than the hose external diameter, and first connecting portion are in the through-hole, first connecting portion and second connecting portion end kickup, the end is opened there is the centre gripping hole, the beneficial effects of the utility model are that: the hose clamp pre-tightened by the spring material is convenient to install, high in efficiency and reliable through the clamping hole.
Description
Technical Field
The invention relates to a hose clamp, in particular to a low-pressure hose clamp.
Background
The hose clamp is used as a soft and hard pipe connecting element in a large amount in engineering machinery and low-pressure systems, can be connected with pipelines of a cooling liquid and an air inlet and exhaust system, and is widely applied to hydraulic systems. The T-shaped hose clamp is generally composed of components such as a strap, an anti-loosening spring, a tensioning bolt and the like, and has the defects of high manufacturing requirement, high cost, poor manufacturability, inconvenient installation and maintenance and incapability of convenient and quick installation especially in places with narrow space.
Disclosure of Invention
The invention aims to solve the problems of high manufacturing cost and inconvenient installation of the low-pressure hose clamp.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a low pressure hose hoop, includes the strap, strap one end is first connecting portion, the strap other end is the second connecting portion, and second connecting portion open has rectangular through-hole, first connecting portion width is less than the through-hole width, and first connecting portion pass the through-hole, the hose hoop internal diameter is less than the hose external diameter, and first connecting portion are in the through-hole, first connecting portion and second connecting portion end kickup, and the end is opened there is the centre gripping hole.
The strap is made of spring steel material; the hose is favorable for pre-tightening the hose with the inner diameter of the hose hoop smaller than the outer diameter of the hose.
Anti-loosening holes are uniformly formed in the hoop, and the number of the anti-loosening holes is more than or equal to 1; the anti-loosening hole clamps the hose to form a bulge to play a role in loosening.
The upward bent part of the end head of the second connecting part comprises the front end of the through hole, so that the hose clamp can form a smooth round surface.
The diameter of the anti-loosening hole is larger than one half of the width of the strap, so that the formed anti-loosening hole is formed.
Compared with the prior art, the invention has the following beneficial effects: the hose clamp pre-tightened by the spring material is convenient to install, high in efficiency and reliable through the clamping hole.
Drawings
FIG. 1 is a schematic view of a low pressure hose throat;
in the figure: 1. strap, 2, first connecting portion, 3, second connecting portion, 4, centre gripping hole, 5, locking hole, 6, through-hole.
Detailed Description
The technical scheme of the utility model a low pressure hose clamp is further explained below with accompanying drawings and embodiment, including strap 1, 1 one end of strap is first connecting portion 2, the strap other end is second connecting portion 3, and second connecting portion 3 is opened there is rectangle through-hole 6, first connecting portion 2 width is less than through-hole 6 width, and first connecting portion 2 passes through-hole 6, the hose clamp internal diameter is less than the hose external diameter, and first connecting portion 2 is in through-hole 6, first connecting portion 2 and 3 end upscrooks of second connecting portion, and the end is opened there is centre gripping hole 4, and strap 1 evenly opens there is anti-loosening hole 5.
The hose clamp base body is preferably formed by blanking spring steel, wherein the first connecting part 2 is narrow, the second connecting part 3 and the strap 1 keep the same width, a through hole 6 is formed in the second connecting part 3, the first connecting part 2 can smoothly penetrate through the through hole 6 in the second connecting part 3, clamping holes 4 are formed in two ends of the first connecting part 2 and the second connecting part 3 respectively, and a certain number of anti-loosening holes 5 are formed in the periphery of the strap 1; after blanking, the throat hoop is rolled into a circular ring shape, and a clamping hole 6 is compressed by using snap spring pliers or other self-made tools during installation, so that the first connecting part 2 moves in the through hole 6 of the second connecting part 3, and the inner diameter of the throat hoop is enlarged for installation; the hose hoop is tightened automatically by the aid of the spring pretightening force after installation, the anti-loosening holes 5 on the circumference of the hose hoop interact with the hose to compress the corresponding parts of the hose to deform and sink into the anti-loosening holes 5 when the pretightening force of the hose hoop is tightened, anti-loosening and axial and radial relative movement limiting are achieved to complete connection of the hose and the hard pipe, meanwhile, the first connecting portion 2 is arranged in the through hole 6 of the second connecting portion 3, the minimum size of the hose hoop is guaranteed, and the hose hoop is convenient to install in a small space.
