Description

A kind of pipe clamp

Technical field

The fixing device that a kind of pipe is connected with pipe, particularly a kind of pipe clamp for being fixed on tube outer diameter.

Background technology

The fixing device that traditional pipe is connected with pipe, usually steel plate punched are into pipe clamp circular Zhou Changwei at two Termination sets the fixing hole of adjustment screw, pipe clamp is fastened outer tube on inner pipe by tightening screw.In order to be able to enable pipe clamp to have The fastening of effect, specially designs and leaves corresponding adjustment distance, i.e. pipe clamp and do not have the full whole circle of bag completely, for pipe clamp after fastening On the space that reserves of two terminations, the measure taken be on the circle in this space plus one with pipe clamp width it is identical, More than the auxiliary pipe clamp of one piece of supplement of gap lengths, to ensure that the whole part of pipe is stuck comprehensively.This traditional pipe clamp Defect is that the clamp molded with steel plate punched will leave more tailing, and these tailings will share each pipe clamp Cost in, along with the cost of auxiliary pipe clamp, totle drilling cost is relatively high.The another pipe clamp for being fixed on rubber tube, by By the pressure of pipe clamp branch elasticity can be lost in rubber tube is long-term, therefore phenomenon that pipe clamp loosens occurs, it is necessary to regular inspection Maintenance.

Number of patent application equally proposes that " existing hose clamp is cold in heat expansion for 201120159801.4 " hose clamp " Diameter change, influence clip fastening force are easily caused under contracting or vibration ".This explanation prior art is implicitly present in solution of being so eager Certainly the problem of, but the technical scheme either in structure and operation is upper or not ideal enough of the actual solution of the invention.

Number of patent application is equally proposed " at the opening outside prior art circumference for 201220413906.2 " seamless clip " It is vacancy, such clip used time has the shortcomings that easily to reveal." inventive technique scheme adds a kind of auxiliary pipe clamp, Really the problem of existing also is solved, but this structure complicates simple pipe clamp, do not increase an auxiliary pipe clamp just, Supervisor's card is also complicated, the increase that cost may be at double, and the hollow-core construction of square tube card also have impact on the fastening force of supervisor's card, category In the technique effect of one " giving one's enemy a wife and lose one's soldiers as well ".

The content of the invention

For above-mentioned problem, a kind of simple in construction, processing technology of the object of the invention offer is simple, no waste mine production It is raw, without the auxiliary pipe clamp being independently arranged, can adjust automatically pipe clamp elasticity pipe clamp.

The technical scheme is that, a kind of pipe clamp, mainly by pipe clamp 1, auxiliary pipe clamp 3, two fixing ends 2, adjustment spiral shells The composition such as silk, sets fixing hole 5 in fixing end 2, and pipe clamp is that a steel wire has been coiled into after fixing end 2 and generates two strands of steel wires and be coiled into pipe The girth of card, fixing hole 5 is located in its fixing end 2, and two terminations of steel wire are coiled into auxiliary tube card 3 respectively and end 4 is constituted separately One fixing end 2, fixing hole 5 is located on auxiliary pipe clamp 3 and end 4.

The positive effect of the present invention is to aid in pipe clamp and pipe clamp（Supervisor's card）Integration, and be coiled into by a steel wire Structure is extremely simple, is adapted to the modern times omnipotent machining of spring, not only technique is simple, production efficiency is high, does not produce tailing, because This this greatly reduce the cost of unit pipe clamp；Pressure of the pipe clamp increase pipe clamp to the unit area of institute's fixing pipe is made of bifilar steel wire Power is good using this pipe clamp engineering reliability；Auxiliary pipe clamp is designed to that spring structure can freely be adjusted according to actual conditions Length；The auxiliary pipe clamp of spring structure can also automatically adjust the tightness of pipe clamp, it is ensured that the connection of such as rubber tube is all the time Keep normal stationary state；The pipe clamp made of spring steel wire is flexible, and tradition is suffered from either assembling or after fixed The advantage that pipe clamp can not have；The fixing end of pipe clamp is rounded, and no corner is not only goodlooking, is also easy to hurt sb.'s feelings；Due to than tradition Pipe clamp material is saved much, therefore can manufacture pipe clamp using stainless steel steel wire, is applicable and is installed under the harsh environments such as water pipe Equipment on, it is than traditional zinc-plated pipe clamp certainly more superior, and everything effect all middle is obtained from simple in construction.

Specific embodiment

Pipe clamp is that a steel wire is coiled into from middle-end（In order to describe convenient narration, the omnipotent machining of spring since middle-end Program is not so）Naturally produce fixing hole 5 after fixing end 2, fixing end 2 be converted into during one it is vertical with pipe clamp circle Fixing end 2.Two strands of steel wires that fixing end 2 comes out are coiled into after the corresponding girth of pipe clamp, and wherein steel wire a termination is coiled into The auxiliary pipe clamp 3 of spring, the profile of auxiliary pipe clamp 3 of spring have with the corresponding radian of pipe clamp circle, can be its design Under slightly biased, the endoporus of pipe clamp 3 is so aided in because being more than screw diameter, therefore auxiliary pipe clamp 3 can keep this radian and be consolidated Fixed pipe closely fits.Two strands of steel wires that similarly fixing end 2 comes out are coiled into after the girth of pipe clamp, the steel wire of another termination It is coiled into drawing spring-like（Gapless, about two circle left and right）End 4 is formed, its front end face fits together with the auxiliary rear end face of pipe clamp 3 Constitute another fixing end 2（A diameter gauge of wire size bigger than the diameter of end 4 for pipe clamp 3 is aided in, center line is on the lower side）, Similarly fixing end 2 is being converted into a fixing end 2 vertical with pipe clamp circle during.Spring-like auxiliary pipe clamp 3 hole and Draw the hole of the end 4 of spring-like to communicate, constitute one and form the fixing hole 5 of another fixing end 2.When fixed screw passes through two Individual fixing end 2, being rotated by screw makes pipe clamp be fixed on tube surface, aids in the spring-like of pipe clamp 3 to be pressed as distance reduces Contracting, so aids in pipe clamp 3 to fill up the adjustment distance that two fixing ends 2 are reserved under the random length in this space, it is ensured that Pipe clamp in 360 degree of scopes is in clamping connection pipe.When caused pipe diameter reduces caused by pipe deformation or other factorses, aid in The spring-like of pipe clamp 3 can automatically adjust the elasticity of pipe clamp according to the change of diameter all the time.
