As shown in Figure 1 and Figure 2, this utility model provides a kind of steel pipe inner wall quick seal coupling, including handle 1, bearing pin 2, Tapered sleeve 8, fixing card lobe 9, polyurethane O are fixed in movable inner core 3, sealing Glais ring 4, spring 5, shell 6, sealing O a7, rear end Type circle 10, inner core connecting rod 11, sealing O b12, front end tapered sleeve 13, elastic spring 14 and test specimen steel pipe 15, handle 1 one end leads to Crossing bearing pin 2 to be connected with shell 6, when snap joint is for docking, handle 1 and shell 6 are in horizontal linear, when pressing down on handle 1 After, handle 1 rotates 90 ° and realizes fast sealing and fix, and movable inner core 3 is connected with shell 6, seals Glais ring 4 and is arranged on activity On the outer wall of inner core 3, movable inner core 3 can be effectively improved exist by being provided with sealing Glais ring 4 on the outer wall of movable inner core 3 Sealing in moving process, spring 5 one end is connected with movable inner core 3, and spring 5 other end is connected with shell 6, before docking Spring 5 is in compressive state by movable inner core 3 extruding, when promotion movable inner core 3 is moved by the rear spring 5 of docking, and then realizes Snap joint is docked with target, seals O a7 and is arranged on the inwall of shell 6, and inner core connecting rod 11 is through rear end fixed cone Set 8 is connected with movable inner core 3, and rear end is fixed tapered sleeve 8 and is connected with shell 6, and polyurethane O 10 is arranged on the side of fixing card lobe 9 On wall, rear end is fixed tapered sleeve 8 and is connected with front end tapered sleeve 13 through fixing card lobe 9, and fixing card lobe 9 is arranged on shell 6 and inner core Between connecting rod 11, it is possible to be effectively improved the anti-skidding anticreep performance of snap joint, improve the ability bearing pressure of snap joint, poly- Urethane O 10 is arranged on the sidewall of fixing card lobe 9, and tapered sleeve 8 and outer fixed by inner core connecting rod 11 through front end tapered sleeve 13, rear end Shell 6 is connected with movable inner core 3, seals O b12 and is fixed on the edge of front end tapered sleeve 13, and tight loop 14 is arranged on inner core connecting rod 11 with the seam crossing of front end tapered sleeve 13, test specimen steel pipe 15 is connected with fixing card lobe 9.
Preferably, fixing card lobe 9 is made up of the tool threaded card lobe of pintongs, six lobes or eight lobes, fixing card lobe 9 with after The fixing tapered sleeve 8 of end and front end tapered sleeve 13 one end that contacts is tapered structure.
Preferably, front end tapered sleeve 13 is pyramidal structure, and realizes in steel pipe with inner core connecting rod 11 and sealing O b12 Wall seals.
Preferably, the sidewall of movable inner core 3 it is provided with and seals the fixing groove that Glais ring 4 matches, connecting with shell 6 Touch.Inner core connecting rod 11 through sealing O b12, tapered sleeve 8 is fixed in front end tapered sleeve 13, elastic spring 14, fixing card lobe 9, rear end, Shell 6, spring 5 are connected with movable inner core 3, pull front end tapered sleeve 13, are fixed the taper of tapered sleeve 8 by front end tapered sleeve 13 and rear end Structure promotes fixing card lobe 9 to expand outwardly, it is achieved to test specimen steel pipe 15 inwall tensioner.
This utility model has the advantage that with good effect: owing to using technique scheme so that this snap joint The principle using handle extruding achieves a butt joint fastening, when being plumbness by handle by horizontal pressing, utilizes the bounce-back of spring to make With realizing front end tapered sleeve and rear end fixed the extruding fastening of tapered sleeve, so utilize front end tapered sleeve and rear end fix tapered sleeve realize right Fixing card lobe outwardly against, and then realize docking of snap joint and steel pipe, it is achieved the rapid abutting joint of snap joint, and general Fixing card lobe is arranged in the middle of inner core connecting rod and test specimen steel pipe, it is possible to be greatly improved the fastness of snap joint, it is to avoid quickly connect The slippage of head.
The work process of this example:
As it is shown in figure 1, handle 1 and movable inner core 3 are in level, now movable inner core 3 will under the pressure of handle 1 Extruding spring 5, now spring 5 is in compressive state, will promote inner core connecting rod when movable inner core 3 is in compressive state 11 move, owing to inner core connecting rod 11 is displaced outwardly so that tapered sleeve 8 and is fixed in front end tapered sleeve 13, rear end to the direction away from shell 6 Be in natural relaxation state between fixing card lobe 9, under the effect of polyurethane O 10, make fixing card lobe 9 to contract, this Time snap joint be in open mode.
As in figure 2 it is shown, press down on handle 1 so that it is during with movable inner core 3 in 90 ° of angles, after being pressed due to handle 1 With the Distance Shortened of movable inner core 3, in turn result in movable inner core 3 and move to handle 1 direction under the effect of spring 5, due to work Motion and then the drive inner core connecting rod 11 of dynamic inner core 3 move to shell 6 direction, and extruding rear end is fixed by the motion of inner core connecting rod 11 Tapered sleeve 8 and front end tapered sleeve 13 realize relative motion, owing to what tapered sleeve 8 contacted with fixing card lobe 9 with front end tapered sleeve 13 fixed in rear end End face is inclined design, fix tapered sleeve 8 in rear end and time front end tapered sleeve 13 carries out relative motion by realize to fixing card lobe 9 to Outer extruding, and then realize the fixing, owing to fixing card lobe 9 is arranged on inner core connecting rod 11 and shell 6 of snap joint and target steel pipe Between, utilize inner core connecting rod 11 and shell 6 to provide support force for fixing card lobe 9, it is possible to increase the stability of snap joint, and For when in steel pipe, pressure is bigger, due in steel pipe during pressure outside, pressure will promote inner core connecting rod 11 to move to shell 6 direction Dynamic, will further fixing card lobe 9 be extruded during inner core connecting rod 11 moves, it is achieved fix the further of card lobe 9 Fastening such that it is able to be prevented effectively from the appearance of snap joint and steel pipe slippage situation, substantially improve common snap joint and bear The shortcoming that pressure is little and service life is low.
Above embodiment of the present utility model has been described in detail, but described content be only of the present utility model preferably Embodiment, it is impossible to be considered for limiting practical range of the present utility model.All according to this utility model application range made equal Deng change and improvement etc., within all should still belonging to patent covering scope of the present utility model.
