Description
Technical field
The utility model is related to pneumatic demoulding field, more particularly to a kind of pneumatic demoulding connecting assembly.
Background technology
The construction materials such as concrete test block, building block are typically all that shaping is poured with concrete, mortar mold.For the ease of
Concrete pressure-testing block is stripped, before concrete cast, in die trial one layer of machine oil of brush, but after concrete formation, or be side
Body, or be cylinder, the inner chamber of whole embedded die trial, the difficulty of the demoulding is than larger.
Different mold releasability modes is different, but a certain degree of damage and demoulding efficiency can be all caused to building block mostly
But, the new stripper mode of the pneumatic demoulding was engendered in recent years, and general this stripping means are therefore connect connecing for air pump
Head, is inserted on the stomata of mold bottom, is then pressed inwardly into air pressure, to reach the effect of the demoulding.
But there is the situation departed from gas replenishment process in the existing pneumatic demoulding, joint, with valve to the safety of operating personnel
In the presence of certain hidden danger.
Utility model content
The purpose of this utility model is to provide a kind of pneumatic demoulding connecting assembly, which solves but the existing pneumatic demoulding,
There is the condition problem departed from gas replenishment process with valve in joint.
Above-mentioned technical purpose of the present utility model technical scheme is that：

State and anticreep groove be provided with the step where the inner side of stop part, opening and the stop part of the valve form axial lock road,
The joint coordinates with the axial grafting in lock road, and the joint and valve inwall rotatable engagement, is provided with and hinders on the joint
The shaft shoulder that stopper inner surface is axially abutted, the end of the joint is provided with the resilient key coordinated with anticreep groove.
Using said structure, when needing to carry out the pneumatic demoulding to concrete, joint is accessed and abutted from lock road
To step, then swivel joint is until resilient key falls into anticreep groove, due to the anti-work of the air pressure butt joint during the demoulding
Firmly vertical in step plane, stop part blocks joint and departed from vertically, if joint departs from, can only circumferentially rotate first,
And resilient key limits circumferentially rotating for joint, security of the joint when inflation is used is fully ensured that, it is to avoid it was being used
Jumped out in journey because circumferentially rotating Er Congsuo roads；In addition, it is vertical with the reaction force direction of air pressure butt joint to circumferentially rotate direction, bullet
Property pin is not influenceed by air pressure amount of force, and the intensity requirement to resilient key is relatively low.
More preferably：The anticreep groove is arranged on the circumferential middle part of stop part.
Using said structure, anticreep groove is at middle part so that after docking the shaft shoulder just with stop part coordinate, stability compared with
It is high.
More preferably：The anticreep groove is two, and is symmetrical arranged.
Using said structure, two anticreep groove stress are symmetrical, and stability is more preferable.
More preferably：Spacing between the inner surface and step of the stop part gradually subtracts from two ends to centre
It is small, and middle part is provided with flush end
Using said structure, it butt joint can be stepped up during rotation, increase its sealing.
More preferably：Mounting hole is provided with the joint, the resilient key includes shank and pre-compressed spring, shank
Coordinate with mounting hole grafting, the pre-compressed spring is arranged between mounting hole and shank.
Using said structure, shank is stopped with mounting hole, makes it circumferential spacing more preferable.
More preferably：The shank is set into multi-diameter shaft, and the aperture of the mounting hole is provided with prevention multi-diameter shaft and slided
The baffle ring gone out, the baffle ring is threadedly coupled with mounting hole, and the small shaft portion of the multi-diameter shaft of the shank passes through baffle ring.
Using said structure, baffle ring can prevent shank from coming off, and the baffle ring of threaded connection also causes the installation of shank more
It is convenient.
More preferably：Handle is provided with the joint, the end of the shank towards pre-compressed spring is provided with drawing
Silk, the wire drawing passes through the bottom hole of mounting hole and is controlled by handle.
Using said structure, handle more easily can be controlled to shank, due to shank under conventional sense it is circumferential
It is not bound by, wire drawing pulls the power also very little needed for shank.
In summary, the utility model has the advantages that：
1st, axial limiting is carried out with limiting section butt joint, it is circumferential spacing with resilient key butt joint progress, fully ensure that and connect
The security of head in use；
2nd, with wire drawing control shank movement, it can not be limited by distance and shank is controlled, control is flexible.
