Abstract
The invention relates to a leaking preventing structure. The leaking preventing structure comprises a hollow base of which the upper part is opened, and a sealing cover arranged on the base body; an inner check ring which is closely clung to the inner wall of the base body is annularly arranged on the inner side of the lower surface of the sealing cover; an outer check ring extends out from the lower part of the side edge part of the sealing cover; the side of the lower part of the outer check ring is annularly inwards overturned to form a clamping ring which is in rotating connection with the outer check ring; a clamping slot in match with the clamping ring is correspondingly formed in the outer wall of the base body. The leaking preventing structure has the advantages that 1) two seals are arranged, so that the sealing performance is superior to that of the traditional sealing mode; 2) the sealing structural form is that all parts are matched, and the inner seal and the outer seal are combined, so that the sealing performance can be effectively ensured; 3) the sealing surface is longer than that in the traditional structural form, and thus the sealing performance is effectively ensured; 4) a sealing pad is arranged on each combining surface so as to ensure the sealing performance of the leaking preventing structure.
Description
Technical field
The present invention relates to a kind of leakage proof structure, belong to technical field of sealing technology.
Background technique
In existing packing structure or cup body structure, generally all adopt be threaded, the conventional Placement such as buckle connection, its structure is simple, can be suitable in general use occasion.
But at some, higher occasion is required to sealability, above-mentioned Placement obviously can not meet seal request, and therefore each production firm devises various leakage proof structure, and general is all comparatively complicated, sealing surface is easily damaged, and its working life is shorter.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide that a kind of structure is simple, sealability fine, and can keep a kind of leakage proof structure of good seal performance for a long time.
The technical solution used in the present invention is for this reason: the matrix that the present invention includes upper opening hollow and the capping be arranged on matrix, and inside described capping lower surface, hoop is provided with the inner shield ring fitted tightly with matrix inwall; An outer back-up ring is stretched out in cover rim subordinate prolongation, the snap ring that outer back-up ring bottom hoop in-flanges is formed and outer back-up ring is rotationally connected, and described matrix outer wall corresponding position is provided with the draw-in groove coordinated with snap ring.
Inner shield ring and matrix inwall, outer back-up ring and matrix outer wall, between snap ring and draw-in groove, establish sealing gasket.
Advantage of the present invention is: 1) the present invention arranges two resealings, and its sealability of more traditional seal form improves greatly; 2) sealing configuration form of the present invention adopts the cooperation of each parts, the mode of sealing, external sealed dual combination in adopting, and sealability obtains effective guarantee; 3) the structural type sealing surface that the present invention is more traditional is longer, more effectively ensure that sealability; 4) what the present invention was last arranges sealing gasket on each mating face, ensure that sealability of the present invention.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
1 be matrix, 2 be capping in figure, 3 be inner shield ring, 4 be outer back-up ring, 5 be snap ring, 6 be draw-in groove, 7 for sealing gasket.
Embodiment
The matrix 1 that the present invention includes upper opening hollow and the capping 2 be arranged on matrix 1, inside described capping 2 lower surface, hoop is provided with the inner shield ring 3 fitted tightly with matrix 1 inwall; Extend under capping 2 edge part and stretch out an outer back-up ring 4, the snap ring 5 that outer back-up ring 4 bottom hoop in-flanges is formed and outer back-up ring 4 is rotationally connected, described matrix 1 outer wall corresponding position is provided with the draw-in groove 6 coordinated with snap ring 5.
Inner shield ring 3 and matrix 1 inwall, outer back-up ring 4 and matrix 1 outer wall, between snap ring 5 and draw-in groove 6, establish sealing gasket 7.
Interior sealing of the present invention refers to: the combination of inner shield ring 3 and matrix 1 inwall, longer in conjunction with the sealing surface formed, and ensure that sealability at first, and add sealing gasket 7 at its sealing surface place, first sealability is guaranteed simultaneously.
Adopt external sealed on the basis of the above: namely outer back-up ring 5 and matrix 1 outer wall form second, and then snap ring 5 and draw-in groove 6 form the 3rd road, and snap ring 5 draw-in groove 6 is while sealing, also plays the connection function of capping 2 and matrix 1; Moreover also respectively add sealing gasket in above-mentioned connecting part, guarantee sealability further.
In sum, the present invention adopts the form of three seals, and the sealing of each road is all linked with one another, and the liquid in matrix 1 does not exist the situation of leakage substantially.
Claims (2)
1. a leakage proof structure, is characterized in that, the matrix comprising upper opening hollow and the capping be arranged on matrix, and inside described capping lower surface, hoop is provided with the inner shield ring fitted tightly with matrix inwall; An outer back-up ring is stretched out in cover rim subordinate prolongation, the snap ring that outer back-up ring bottom hoop in-flanges is formed and outer back-up ring is rotationally connected, and described matrix outer wall corresponding position is provided with the draw-in groove coordinated with snap ring.
2. a kind of leakage proof structure according to claim 1, is characterized in that, inner shield ring and matrix inwall, outer back-up ring and matrix outer wall, establishes sealing gasket between snap ring and draw-in groove.
