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 for sealed pipe fittings 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 that metal tube is locked connection fast that are used for, and these clamp 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 of connection fast, these clamp are configured to by two calipers and two fixed supports, and two calipers are over against being provided with between two fixing support racks, and are hinged by rotating shaft and fixing support rack respectively; Caliper is binding clip above pin joint, and the pin joint below is respectively equipped with jaw for the pincers handle on the binding clip, and the both sides of 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.
Above-mentioned pincers handle is a Mechanical Driven, and machine power derives from electric energy or hydraulic pressure energy, is provided with during Mechanical Driven to drive tie point or drive acting surface on the pincers handle, is provided with back-moving spring between two calipers.
As further improvement, described rotating shaft is fixedly installed on the fixing support rack by slotted collar is set.
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, it is extremely convenient to use.In addition, the utility model adopts fixing support rack to be hinged with two calipers respectively, and the body damage has been avoided in the circular arc skew of carrying out when reducing jaw like this and clamp together.The utlity model has characteristics simple in structure, easy to use.
