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.
