Abstract
The utility model relates to a joint mechanism for a pressuring and inflating device. The joint mechanism comprises a second joint, wherein an annular groove is formed inside the second joint, a rubber ring is placed in the annular groove, and an internal thread is arranged on the inner wall surface of the annular groove. The joint mechanism further comprises a first joint, wherein a step is formed inside the first joint, an external thread connected with the internal thread in a matching manner is arranged on the outer circumferential surface of the step, a trapezoidal groove is formed in the lower part of the first joint, the first joint is screwed in the second joint, a spring is arranged in the trapezoidal groove, the bottom of the first joint supports against the rubber ring, and through holes penetrating through a pipe are formed in the middles of the second joint and the first joint. The joint mechanism is reasonable in structure and convenient and simple to operate; the joints are pressed by manufacturing a straight pipe, the pressing procedure is reduced, the processing cost is lowered, and the work efficiency is improved.
Description
Technical field
The utility model relates to suppresses inflator technical field, especially a kind of inflator joint mechanism of suppressing.
Background technique
At present, suppress inflator and be widely used, in use, conventionally need check whether to leak gas, when suppressing, when encountering connecting tube and be straight tube, in prior art, common way is on straight tube, to weld a female adapter, while conveniently suppressing, because pressure causes greatly pipeline, pushes away.But, the shortcoming of the method is that operation is more numerous and diverse, it welds a female adapter after straight tube need to being lengthened, and after then having suppressed, also joint will be cut off, and need straight tube to polish smooth, under multiple operation so, 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.
Model utility content
The applicant is for the shortcoming in above-mentioned existing production technology, a kind of rational in infrastructure inflator joint mechanism of suppressing is provided, thereby increases work efficiency, and simplifies and suppresses operation, reduces costs.
The technological scheme that the utility model adopts is as follows:
An inflator joint mechanism, comprises the second joint, and described the second joint inside is provided with circular groove, in described circular groove, is placed with rubber ring, on the internal face of described circular groove, has internal thread; Also comprise the first joint, described the first joint inside is formed with step, be positioned on the outer peripheral surface of step and have the outside thread being connected with screw-internal thread fit, and be positioned at the first joint bottom and be provided with dovetail groove, described the first joint screws in the second joint, and in dovetail groove mounting spring, the bottom of described the first joint and rubber ring butt; Described the second joint and the first joint middle part are provided with the through hole through pipe.
Further improvement as technique scheme:
The height a of described the second joint is 80mm, and the degree of depth of described the second internal thread that joint leaves is that b is 30mm.
The beneficial effects of the utility model are as follows:
The utility model is rational in infrastructure, easy and simple to handle, by making straight tube, suppresses joint, reduces and suppresses operation, cuts down finished cost, and increases work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
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, embodiment of the present utility model is described.
As shown in Figure 1, the present embodiment suppress inflator joint mechanism, comprise that the second joint 7, the second joint 7 inside are provided with circular groove 6, in circular groove 6, be placed with rubber ring 5, on the internal face of circular groove 6, have internal thread; Also comprise the first joint 1, the first joint 1 inside is formed with step 2, be positioned on the outer peripheral surface of step 2 and have the outside thread being connected with screw-internal thread fit, and be positioned at the first joint 1 bottom and be provided with dovetail groove 3, the first joint 1 screws in the second joint 7, and at bottom and rubber ring 5 butts of interior mounting spring 4, the first joints 1 of dovetail groove 3; The second joint 7 and the first joint 1 middle part are provided with the through hole through pipe.
The height a of the second joint 7 is 80mm, and the degree of depth of the second joint 7 internal thread of opening is that b is 30mm.
In actual fabrication process, first do one and suppress mould, doing one, to have internal thread the second joint 7, the 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, in this circular groove 6, inserts rubber ring 5; Then do again one with supporting the first joint 1 of the second joint 7, the spring 4 of the interior placement of dovetail groove 3 at the first joint 1 head, links together the first joint 1 and the second joint 7.
In practical work process, when straight tube is suppressed, straight tube is stretched in the through hole of this first joint 1 and the second joint 7 middle parts opening, 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, and it can not be moved on above-below direction, and being constantly screwed into due to the first joint 1, rubber ring 5 is inwardly expanded, thereby constantly compress straight tube, play fastening effect at this point, so just can suppress.It is simple in structure, guarantees to suppress reliable operation, easy to use.
More than describing is to explanation of the present utility model, is not the restriction to model utility, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
