Abstract
The utility model discloses a kind of seal arrangement of through hole, aim to provide a kind of easy to use, effectively can realize the seal arrangement of workpiece through-hole sealing.It comprises two O RunddichtringOs; The handpiece of the vertical used through hole of one band, in the through hole that workpiece just can be stretched in lower end and lower end surface is provided with the first end difference of one of them O RunddichtringO of suit; One head under, run through the snap bolt of described vertically used through hole, its head just can stretch in the through hole of workpiece, and the upper-end surface of head is provided with the second end difference of another O RunddichtringO of suit; Be screwed in the nut on snap bolt; And the spacer be set on the first end difference and the second end difference; Two described O RunddichtringOs are positioned at the two ends up and down of spacer; The through-hole wall gluing, sealing with workpiece is realized by tightening nut extruding O RunddichtringO.The through hole sealing that the utility model is applicable to that through hole face area is little, end face non-bolt hole or end face are black skin uses.
Description
Technical field
The utility model relates to the performing leak test technical field of through hole, especially relates to a kind of seal arrangement of through hole.
Background technique
The sealing relating to through hole is needed, to carry out performing leak test to workpiece in a lot of industry.Traditional method uses the tapped hole of workpiece itself, compresses end face seal through hole with pressing plate and rubber pad.But the end face unthreaded hole of some workpiece, some face area is less, and sealing place position is compact, is not suitable for thread mill drilling, and the workpiece end face also had is black skin, is not suitable for sealing with end face.
Summary of the invention
The utility model overcomes shortcoming of the prior art, provides a kind of easy to use, effectively can realize the seal arrangement of workpiece through-hole sealing.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of seal arrangement of through hole, comprising:
Two O RunddichtringOs;
The handpiece of the vertical used through hole of one band, in the through hole that workpiece just can be stretched in lower end and lower end surface is provided with the first end difference of one of them O RunddichtringO of suit;
One head under, run through the snap bolt of described vertically used through hole, its head just can stretch in the through hole of workpiece, and the upper-end surface of head is provided with the second end difference of another O RunddichtringO of suit;
Be screwed in the nut on snap bolt; And
Be set in the spacer on the first end difference and the second end difference;
Two described O RunddichtringOs are positioned at the two ends up and down of spacer; The through-hole wall gluing, sealing with workpiece is realized by tightening nut extruding O RunddichtringO.
Preferably, the external wall cross-section of described handpiece is circular.
Preferably, the external wall cross-section of described handpiece is oval.
Preferably, the bottom of described handpiece outer wall is provided with one and can be overlapped on annular flange on the through hole end face of workpiece.
Compared with prior art, the utility model tool has the following advantages:
(1) structure of the present utility model has an entirety of one's own, and before nut is not tightened, O RunddichtringO is free state, and the radial dimension of device bottom is less than the through hole that need seal, and easily can put into through hole.When O type circle to arrive in hole behind appropriate location, hold with a hand stop gripping member fastening nut, make the extrusion of O RunddichtringO, external diameter swells, and fits tightly with through-hole wall the sealing realized through hole.When having sealed after test completes, then unscrew nut, O RunddichtringO is returned to original position, and device easily can exit through hole, and whole process is to through hole hole wall not damaged.
(2) the utility model is when spatial position is limited, directly seals the aperture of through hole, and the mounting or dismounting of whole device are convenient, and sealing is reliable, can Reusability, operates simple and easy.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the enlarged view of part A in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 and Figure 2 shows that the specific embodiment of seal arrangement of through hole, comprising: two O RunddichtringOs 4; The handpiece 3 of the vertical used through hole of one band, in the through hole that workpiece 10 just can be stretched in lower end and lower end surface is provided with the first end difference 6 of one of them O RunddichtringO 4 of suit; One head under, run through the snap bolt 2 of described vertically used through hole, its head just can stretch in the through hole of workpiece 10, and the upper-end surface of head is provided with the second end difference 7 of another O RunddichtringO 4 of suit; Be screwed in the nut 1 on snap bolt 2; And the spacer 5 be set on the first end difference 6 and the second end difference 7; Two described O RunddichtringOs 4 are positioned at the two ends up and down of spacer 5; Extrude O RunddichtringO 4 by tightening nut 1 and realize the through-hole wall gluing, sealing with workpiece 10.
The external wall cross-section of described handpiece 3 is preferably convenient to hand-held for circular or oval.The bottom of described handpiece 3 outer wall is provided with one can be overlapped on annular flange on the through hole end face of workpiece 10, can realize the restriction that sealing device hermetic unit puts into lead to the hole site axial depth.
Structure of the present utility model has an entirety of one's own, and before nut is not tightened, O RunddichtringO is free state, and the radial dimension of device bottom is less than the through hole that need seal, and easily can put into through hole.When O type circle to arrive in hole behind appropriate location, hold with a hand stop gripping member fastening nut, make the extrusion of O RunddichtringO, external diameter swells, and fits tightly with through-hole wall the sealing realized through hole.When having sealed after test completes, then unscrew nut, O RunddichtringO is returned to original position, and device easily can exit through hole, and whole process is to through hole hole wall not damaged.The utility model, when spatial position is limited, directly seals the aperture of through hole, and the mounting or dismounting of whole device are convenient, and sealing is reliable, can Reusability, operates simple and easy.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
