Abstract
The utility model relates to calipers, in particular to a caliper jaw used for the quick locking connection of metal pipe fittings. Both sides of the jaw are respectively provided with polygon mouths or circular mouths, and an annular groove with an arc-shaped cross section is arranged in the middle of the jaw. When the caliper jaw is used, a pipe is inserted into a connecting end, then the jaw is clamped at the connecting end and is crimped at the inner side and the outer side of the arc-shaped annular groove at one time to realize the quick connection of the pipe fittings, and the use is very convenient. The jaw has a simple structure and is convenient to use.
Description
Technical field
The utility model relates to a kind of clamp, relates in particular to a kind of clamp jaw that metal tube is locked connection fast that is used for.
Background technology
Conventional pipelines and connector thereof are threaded usually or plough groove type connects; Be connected firmly for reaching, tight, non-leakage purpose, generally need reprocess pipe fitting end, promptly open hinge screw thread or open channels at the port of pipe fitting so that be connected, so just damaged, weakened the intensity of pipe fitting end with internal thread or groove.For this reason, when producing pipe fitting, because ridge and groove have the certain height or the degree of depth, the wall thickness of pipe fitting just need be reserved as the surplus of machining screw tooth or groove, these cause the whole wall thickness of pipe fitting to be much higher than the size that real fluid pressure sets, it is actual needed wall thickness, design limiting just because of syndeton, require processed pipe fitting that certain intensity will be arranged, promptly certain wall thickness will be arranged, in addition, pipe fitting during fabrication, tube material is wasted in a large number, and this has increased material cost virtually, has raised the market price of product.
Chinese invention patent (application number: 200610017854.6 applyings date: 2006-05-20) disclose a kind of thin-wall metal pipe quick-locking connection structure, it comprises pipe fitting joint, body, sealing ring, external compression nut and roof pressure ring, the inwall of pipe fitting joint link reaches the outer shoulder hole in the body that is disposed with by the lining, shoulder hole in bulge loop groove and the roof pressure ring, the link end arranged outside of pipe fitting joint has the screw thread external tapping, the link tube wall protuberance of body forms a circle pushing tow bulge loop, the sheathed roof pressure ring of body is arranged on pipe fitting joint the inside, and locks body fast and be connected with pipe fitting joint to be set on external compression nut on the body.This structure tension, compression strength height, good seal performance is mainly used in feedwater, drinking water industry or liquid and carries industry.But the number of spare parts that relates to of this structure is many, and this has also increased production cost.
For this reason, the applicant has invented a kind of metal tube syndeton (applying for a patent simultaneously) of locking fast, this structure is made up of pipe joint and pipe, described pipe joint comprise body and link, described pipe is plugged in the link, inner ring at link is provided with the arc cannelure, is provided with the sealing ring that is used to seal pipe and link inwall in the arc cannelure, and link adopts polygon or the circular mouth of pressing respectively in the arc cannelure inboard and the outside.This structure is after pipe is inserted into link, as long as can realize promptly that with the crimping in the outside the quick of pipe fitting is connected in arc cannelure inboard at link, it is extremely convenient to use.This structure has simple in structure, and is easy to use, and anti-pulling and sealing property be characteristics preferably all, reduced production cost simultaneously again.
Summary of the invention
The purpose of this utility model provides a kind of clamp jaw that metal tube is locked connection fast that is used for, and the clamp with this jaw can realize fast that the locking of metal tube connects, and has characteristics simple in structure, easy to use.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
Be used for metal tube and lock the clamp jaw of connection fast, the both sides of this jaw are respectively equipped with polygon mouth or circular port, and the centre of jaw is provided with the annular groove that the cross section is a circular arc.
As further improvement, a side of above-mentioned jaw is the polygon mouth, and opposite side is a circular port.
As further improvement, be provided with the changeover portion circular port between above-mentioned polygon mouth and the annular groove.
As further improvement, above-mentioned polygon mouth is the regular hexagon mouth.
When using, pipe is inserted into link after, the jaw pincers can be realized promptly that with the crimping in the outside the quick of pipe fitting is connected at link in that the arc cannelure is inboard, use and conveniently.The utlity model has characteristics simple in structure, easy to use.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made a detailed explanation.
As shown in Figure 1 and Figure 2 be used for the clamp that metal tube is locked connection fast, these clamp are made of two calipers 1 and two fixing support racks 2, two calipers 1 are over against being provided with between two fixing support racks 2, and be hinged by rotating shaft 3 and fixing support rack 2 respectively, rotating shaft 3 is fixedly installed on the fixing support rack 2 by slotted collar 4 is set.Caliper 1 is binding clip 5 above pin joint, and the pin joint below is respectively equipped with jaw 7 for pincers handle 6 on the binding clip 5.As shown in Figure 3, Figure 4, a side of jaw 7 is a regular hexagon mouth 9, and opposite side is a circular port 10, and the centre of jaw 7 is provided with the annular groove 11 that the cross section is a circular arc, is provided with changeover portion circular port 12 between regular hexagon mouth 9 and the annular groove 11.
Above-mentioned pincers handle 6 is a Mechanical Driven, and machine power derives from electric energy or hydraulic pressure energy,, be provided with on the handle 6 to drive tie point 8 or drive between 13, two calipers 1 of acting surface at pincers during Mechanical Driven and be provided with back-moving spring.
Certainly above-mentioned clamp are a kind of mode, and jaw of the present utility model can be arranged on the clamping apparatus of various deformation mode.
The quick syndeton of locking of metal tube as shown in Figure 5, this structure is made up of pipe joint and pipe, described pipe joint comprises body and link, described pipe is plugged in the link, inner ring at link is provided with the arc cannelure, is provided with the sealing ring that is used to seal pipe and link inwall in the arc cannelure.Crimping clamps together to pipe connecting structure to adopt the utility model, and forming respectively in arc cannelure both sides and pressing mouth, the pressure mouth of arc cannelure inboard is that regular hexagon is pressed mouth, and the pressure mouth of arc ring slot outside is the circular mouth of pressing.
