Abstract
The utility model relates to a portable expansion connection tube device which is composed of an expansion tube gun body, a front end cap, an expansion tube head, a front handle, a back handle and a high pressure hose. The portable expansion connection tube device is characterized in that a movable cylinder body is sheathed in the expansion tube gun body; a piston is sheathed in the movable cylinder body. When one end of the movable cylinder body is stressed by liquid pressure, the movable cylinder body can move in the expansion tube gun body along the direction of acting force, and the piston is static in the expansion gun body and moves corresponding to the cylinder body. Liquid is pushed and pressed to generate liquid pressure for increasing the pressure by multiple times to act on the expansion tube head after the acting surface of the piston is changed and cut. The utility model has the advantages that the length of the expansion tube gun body is reduced; the volume and the weight of the portable expansion connection tube device are reduced; the portable expansion connection tube device has simple structure and convenient manufacture and is suitable for working in the working condition of narrow environment.
Description
The utility model relates to a kind of expanded joint technology that is widely used in pipe tube sheets such as heat exchanger, condensate cooler, boiler, particularly portable expanded joint pipe unit.
Use at present the expand tube rifle to adopt the piston segmentation to become on the extending direction of pressure position to cut and realize pressure multiplier, this structure makes expand tube rifle body long especially, and volume is big, and weight also greatly and use inconvenience.
The purpose of this utility model is to provide that a kind of length is short, volume is little, lightweight expand tube rifle.
Technical solution of the present utility model:
A kind of portable expand tube rifle is made up of expand tube rifle body, drive end bearing bracket, expand tube head, front hand grip, back handle, high-pressure hose.It is characterized in that being set with a mobile cylinder body in the expand tube rifle body, be set with a piston in the mobile cylinder body.When mobile cylinder body one end liquid body pressure is done the time spent, it moves in expand tube rifle body along force direction, piston is motionless in the expand tube body, the movement of cylinder block but it relatively moves, and it becomes a section acting surface pusher press liquid generation fluid pressure and realizes that pressure multiplier acts on the expand tube head.
Advantage of the present utility model is, has shortened the length of expand tube rifle body, has reduced volume, has alleviated weight, and simple in structure, is convenient to processing, use small and exquisite flexibly, be applicable to the narrow environment of condition of work under and work.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1, a kind of portable expand tube rifle is made up of expand tube rifle body 1, drive end bearing bracket 2, expand tube head 3, front hand grip 4, back handle 5, high-pressure hose 6.Drive end bearing bracket 2 spins with expand tube rifle body 1, and drive end bearing bracket 2 has an axially extending bore, and an end communicates with expand tube rifle body 1 inner chamber, and the other end is connected with expand tube head 3.Half through hole is arranged on the RADIAL of drive end bearing bracket 2, and an end communicates with axially extending bore, and the other end is connected with high-pressure hose 6 by a check valve 10.Front hand grip 4 is fixed on drive end bearing bracket 2 outward flanges, and back handle 5 is fixed on the outward flange of expand tube rifle body 1, and a circle hole shape cavity 12 is arranged in the expand tube rifle body 1, and accent place and drive end bearing bracket 2 spin, and the bottom, chamber has a through hole 11 to be connected with high-pressure hose 6.Be set with a mobile cylinder body 7 in the cavity 12 mutually movingly, a circle hole shape cavity 8 is arranged in the mobile cylinder body 7, the accent place is set with a piston 9, each other movingly towards drive end bearing bracket 2 in the cavity 8.One axially extending bore is arranged on the piston 9, and an end communicates with axially extending bore on the drive end bearing bracket 2, and the other end communicates with the circle hole shape cavity 8 of mobile cylinder body 7, and it is return port that the RADIAL of an end piston 9 of forward end cap 2 has a through hole.After the through hole of high-pressure hose 6 internal pressure liquid by expand tube rifle body 1 enters cavity, promote cylinder body 7 and move along the pressure action direction in cavity 12, through hole, drive end bearing bracket 2 through holes by piston 9 after the liquid supercharging after the change of 7 ends of mobile cylinder body cuts in the compressing cavity 8 act on the expand tube head 3.Liquid during return in another root high-pressure hose 6 makes mobile cylinder body 7 returns at the bottom of opening the axially extending bore of check valve 10 by drive end bearing bracket 2, chamber that the piston axially extending bore acts on mobile cylinder body 7 by radially half through hole on the drive end bearing bracket 2, prepares to remake next action.
Claims (3)
