Description
Technical field
The present invention relates to a kind of rapid pipe joint, refer to a kind of rapid pipe joint that can conveniently make, reduce cost, maintain fast, reduce fault and can use safely especially.
Background technique
Please cooperate referring to as shown in Figure 9; Rapid pipe joint 70 of the prior art generally is used for the linking of pipeline and is provided with a body 71, a positioning seat 72, a valve seat 73 and a frame 74; Wherein this body 71 is that a hollow cylinder and an end are in order to be connected with an air compressor (figure does not show); The other end of this positioning seat 72 and this body 71 be screwed and outside spaced surface be equipped with a plurality of sheathed holes 721; In each sheathed hole 721, be provided with a positioning bead 722; This valve seat 73 is located in this body 71 and is provided with the suction port 731 that is connected with body 71 inside, and this frame 74 is sheathed on the outer surface of this positioning seat 72 movably and leans with each positioning bead 722, and this frame 74 is provided with one and the pushing clamping spring 741 that leans of this body 71 in inside;
Yet though existing rapid pipe joint 70 can provide the effect on a quick connecting pipe road, existing rapid pipe joint 70 not only during fabrication; Must make this body 71 and this positioning seat 72 respectively; Can increase relatively and make required cost and time, and when assembling, then must this body 71 be screwed togather assembling with this positioning seat 72, quite inconvenient; In addition; The body 71 and the positioning seat 72 of existing rapid pipe joint 70 screw togather the place, after long-time use, are easy to generate the situation of gas leak, not only can't carry out the connection of pipeline exactly and can hide danger;
Moreover, though existing rapid pipe joint 70 can combine with a tool joint pin (figure does not show) through the mode of each positioning bead 722 slip, use transmission and the use of carrying out gas; But when using the back desire that this tool joint pin and existing rapid pipe joint 70 are separated, need move this frame 74, each positioning bead 722 and this tool joint pin are separated and remove the buckle state with hand push; And then tool joint pin can from existing rapid pipe joint 70, be ejected, but in the process that ejects, because this valve seat 73 still is in the state of ventilation; Therefore, the impulse force of pressurized gas can quicken both separation, and this moment is not if firmly catch the pipe that is connected with tool joint pin; Then this pipe may produce the situation of disorderly getting rid of because of the impulse force of pressurized gas, and then causes the phenomenon of injuring the operator, so; When existing rapid pipe joint 70 is separated with tool joint pin, can receive the influence of gas and the defective that has wink to hold to wash open, not only cause the inconvenience of work; Also hiding danger, improvements are in addition really being arranged.
Summary of the invention
