Abstract
The present invention relates to one and suppress inflator joint mechanism, comprise the second joint, described second joint inside is provided with circular groove, rubber ring is placed with in described circular groove, the internal face of described circular groove has internal thread: also comprise the first joint, described first joint inside is formed with step, the outer peripheral surface being positioned at step has the outside thread be connected with screw-internal thread fit, and be positioned at the first joint bottom and be provided with dovetail groove, described first joint screws in the second joint, and in dovetail groove mounting spring, the bottom of described first joint abuts with rubber ring; The through hole through pipe is provided with in the middle part of described second joint and the first joint.The present invention is rational in infrastructure, easy and simple to handle, suppressing joint, reducing and suppressing operation, cutting down finished cost, increase work efficiency by making straight tube.
Description
Technical field
The present invention relates to and suppress inflator technical field, especially one suppresses inflator joint mechanism.
Background technique
At present, suppress inflator and be widely used, in use, whether usual needs inspection leaks gas, when suppressing, when encountering connecting tube and being straight tube, in prior art, common way on straight tube, welds a female adapter, because pressure causes greatly pipeline to push away when conveniently suppressing.But, the shortcoming of the method is that operation is more numerous and diverse, it needs straight tube to lengthen a rear welding female adapter, after then having suppressed, also joint will be cut off, and need straight tube to polish smooth, under so multiple operation, pipe to a certain extent can be impaired, distortion, and therefore pipe and the direct weld seam of end socket also can may ftracture, cause product leakage.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of and rational in infrastructure suppresses inflator joint mechanism, thus increase work efficiency, simplify and suppress operation, reduce costs.
The technical solution adopted in the present invention is as follows:
One suppresses inflator joint mechanism, comprises the second joint, and described second joint inside is provided with circular groove, is placed with rubber ring, the internal face of described circular groove has internal thread in described circular groove; Also comprise the first joint, described first joint inside is formed with step, the outer peripheral surface being positioned at step has the outside thread be connected with screw-internal thread fit, and be positioned at the first joint bottom and be provided with dovetail groove, described first joint screws in the second joint, and in dovetail groove mounting spring, the bottom of described first joint abuts with rubber ring; The through hole through pipe is provided with in the middle part of described second joint and the first joint.
Further improvement as technique scheme:
The height a of described second joint is 80mm, described second joint open internal thread the degree of depth be b be 30mm.
Beneficial effect of the present invention is as follows:
The present invention is rational in infrastructure, easy and simple to handle, suppressing joint, reducing and suppressing operation, cutting down finished cost, increase work efficiency by making straight tube.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, the first joint; 2, step; 3, dovetail groove; 4, spring; 5, rubber ring; 6, circular groove; 7, the second joint.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the present embodiment suppress inflator joint mechanism, comprise the second joint 7, second joint 7 inside and be provided with circular groove 6, be placed with rubber ring 5 in circular groove 6, the internal face of circular groove 6 has internal thread; Also comprise the first joint 1, first joint 1 inside is formed with step 2, the outer peripheral surface being positioned at step 2 has the outside thread be connected with screw-internal thread fit, and be positioned at the first joint 1 bottom and be provided with dovetail groove 3, first joint 1 screws in the second joint 7, and the bottom of mounting spring 4, first joint 1 abuts with rubber ring 5 in dovetail groove 3; The through hole through pipe is provided with in the middle part of second joint 7 and the first joint 1.
The height a of the second joint 7 is 80mm, the second joint 7 open internal thread the degree of depth be b be 30mm.
In actual fabrication process, first do one and suppress mould, doing one, to have internal thread second joint 7, second joint 7 length a be 80mm, and the depth of internal thread b that opens is 30mm, then in the second joint 7, makees a circular groove 6, inserts rubber ring 5 in this circular groove 6; Then make first joint 1 supporting with the second joint 7 again, in the dovetail groove 3 of the first joint 1 head, place a spring 4, the first joint 1 and the second joint 7 are linked together.
In practical work process, when straight tube is suppressed, straight tube is stretched in the through hole opened in the middle part of this first joint 1 and the second joint 7, then the first joint 1 and the second joint 7 are constantly tightened, because have spring 4 in the first joint 1, spring 4 props up rubber ring 5, makes it can not be moved in the vertical direction, and being constantly screwed into due to the first joint 1, rubber ring 5 is inwardly expanded, thus constantly compress straight tube, play fastening effect at this point, so just can suppress.Its structure is simple, ensures to suppress reliable operation, easy to use.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
