Abstract
The utility model relates to a pressure clamp used for the connection of large sized pipe fittings. Two handles are respectively hinged on a connecting plate through a respective handle shaft; the front ends of the handles are respectively hinged with a half annular jaw; an annular rib is arranged in the jaw; the intersecting part of the handles is provided with an inner positioning pin roller and an outer positioning pin roller; the insides of the tail sections of the handles are provided with symmetrical force application inclined planes.
Description
The utility model relates to a kind of Pressure clamp, especially for the clamp of large scale plastic-aluminum pipe fitting connection.
Compare with coating steel pipe, cast iron pipe in view of plastic-aluminum pipe, pvc pipe and to have long, free of contamination characteristics of life-span, country has formally hereinafter banned use of coating steel pipe, cast iron pipe, replaces with plastic-aluminum pipe, pvc pipe.The Aluminium-plastic pipe joint connector that uses is the screw thread ferrule-type compression joint at present, promptly utilizes nut that a slightly flexible brass band distortion and realization pipe are connected.But this kind connected mode poor reliability is in the environment of especially big in the temperature difference, vibration.If force pipe fitting to form annular tongue, firmly connect with pipe joint with the annular pincers, then the reliable rows problem can solve, but common clamp can't produce enough pincers power.
The purpose of this utility model provides a kind of large sized fittings of can forcing and forms the clamp of annular tongue with pipe joint.
Two handles of the utility model clamp are hinged on the joint cover with separately Handle axis respectively; Each hinged one semi-circular jaw of handle front end has annular ridge in the jaw; Positioning roller and outside fix roller in the handle infall is provided with; Handle afterbody inboard is provided with the application of force inclined-plane of symmetry.
For the pipe fitting that makes clamp adapt to different tube diameters connects, be provided for changing the fixture block of jaw diameter in the described jaw.
Have the dowel hole that connects in hydraulic test on the described joint cover.
Change between the described handle and be provided with back-moving spring.
Earlier semi-circular jaw is relayed outward into pipe fitting in use, close up again.The roller pushing tow handle afterbody inboard of hydraulic tool is provided with the application of force inclined-plane of symmetry, utilize the boosting function of inclined-plane and lever, make jaw produce the power of three times sensing caliber, make the overcoat metallic sheath of pipeline connecting parts produce groove, cause the flexible pipe that connected to produce elasticity and plastic deformation and undergauge reaches the effect fastening, sealing that connects.
The utility model has the advantages that the principle of utilizing inclined-plane and lever, it is big that reinforcement effect obviously clamps power; Simple on the structure, compact, can satisfy large-sized plastic-aluminum pipe fitting connection request; Dependable performance.
Further specify the utility model below in conjunction with accompanying drawing:
Fig. 1 is the utility model front view
Fig. 2 is the view after Fig. 1 removes joint cover
Fig. 3 is the annexation figure of joint cover and Handle axis
With reference to accompanying drawing: two handles 2 of the utility model clamp are hinged on the joint cover 1 with separately Handle axis 4 respectively, and Handle axis 4 links to each other with trip bolt 9 by back-up ring 8 with joint cover 1; Each hinged one semi-circular jaw 5 of handle front end has annular ridge in the jaw 5; Positioning roller 6 and outside fix roller 11 in the handle infall is provided with; Handle 2 afterbody inboards are provided with the application of force inclined-plane 10 of symmetry.
For the pipe fitting that makes clamp adapt to different tube diameters connects, be provided for changing the fixture block of jaw diameter in the described jaw.
Have the dowel hole 12 that connects in hydraulic test on the described joint cover.
Change between the described handle and be provided with back-moving spring 7.Play pretension and closed at any time effect.
Earlier with semi-circular jaw 5 outer relaying, close up again in use into pipe fitting.The roller pushing tow handle 2 afterbody inboards of hydraulic tool are provided with the application of force inclined-plane 10 of symmetry, utilize the boosting function of inclined-plane and lever, make jaw produce the power of three times sensing caliber, make the overcoat metallic sheath of pipeline connecting parts produce groove, cause the flexible pipe that connected to produce elasticity and plastic deformation and undergauge reaches the effect fastening, sealing that connects.
The utility model has structurally adopted the form of two rotating shafts, two anchor points, a pair of joint cover, fixture block and handle one.When the pincers open and close, the thorny separately arbor rotation of two handles, and under the constraint of joint cover, locate, guarantee the involutory accuracy of jaw in two positions of open and close by two positioning rollers.
