Abstract
The invention discloses a through hole sealing device which is convenient to use and can effectively seal a workpiece through hole. The device comprises two O-type sealing rings, a handheld element provided with a vertical through hole, a round-headed bolt, a nut and a spacer, wherein the lower end of the handheld element can extend into the workpiece through hole, and the lower end face of the handheld element is provided with a first step portion sleeved with one O-type sealing ring; the head portion of the round-headed bolt is downward and penetrates through the vertical through hole, the head portion of the round-headed bolt can extend into the workpiece through hole, and the upper end face of the head portion is provided with a second step portion sleeved with the other O-type sealing ring; the nut is screwed on the round-headed bolt; the first step portion and the second step portion are sleeved with the spacer; the two O-type sealing rings are located on the upper end and the lower end of the spacer respectively; attachment and sealing of the inner wall of the workpiece through hole are achieved due to the fact that the nut is screwed and extrudes the O-type sealing rings. The through hole sealing device is suitable for sealing through holes with small end face areas and without bolt holes or through holes with blank faces as end faces.
Description
Technical field
The present invention relates to the performing leak test technical field of through hole, especially relate to a kind of seal arrangement of through hole.
Background technique
Need to relate to the sealing of through hole in a lot of industries, to workpiece is carried out to performing leak test.Traditional method is to use the tapped hole of workpiece itself at the through hole end face of need sealing, compresses end face through hole is sealed with pressing plate and rubber pad.But the end face of some workpiece is unthreaded hole around, and some face area is less, and sealing place position compactness, is not suitable for thread mill drilling, and the workpiece end face also having is black skin, is not suitable for sealing with end face.
Summary of the invention
The present invention has overcome shortcoming of the prior art, provides a kind of easy to use, can effectively realize the seal arrangement of workpiece through-hole sealing.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of seal arrangement of through hole, comprising:
Two O RunddichtringOs;
One band is vertically used to the handpiece of through hole, and lower end just can be stretched in the through hole of workpiece 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 described snap bolt of being vertically used to through hole, its head just can stretch in the through hole of workpiece, and the upper-end surface of head be provided with suit another O RunddichtringO the second end difference;
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; By screwing, nut extruding O RunddichtringO is realized and the through-hole wall gluing, sealing of workpiece.
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 an annular flange that can be overlapped on the through hole end face of workpiece.
Compared with prior art, tool of the present invention has the following advantages:
(1) structure of the present invention 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 needs sealing, can easily put into through hole.When O type circle arrives in hole behind appropriate location, grip stop gripping member fastening nut with hand, make the extrusion of O RunddichtringO, external diameter swell, fits tightly with through-hole wall the sealing realizing through hole.After having sealed test and completing, then unscrew nut, O RunddichtringO is returned to original position, and device can easily exit through hole, and whole process is to through hole hole wall not damaged.
(2) in the situation that the present invention being limited in spatial position, the aperture of through hole is directly sealed, the mounting or dismounting of whole device are convenient, and sealing is reliable, can Reusability, operate simple and easy.
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of one embodiment of the invention;
Fig. 2 is the enlarged view of A part in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not paying the every other embodiment who obtains under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 and Figure 2 shows that the specific embodiment of seal arrangement of through hole, comprising: two O RunddichtringOs 4; One band is vertically used to the handpiece 3 of through hole, and lower end just can be stretched in the through hole of workpiece 10 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 described snap bolt 2 of being vertically used to through hole, its head just can stretch in the through hole of workpiece 10, and the upper-end surface of head be provided with suit another O RunddichtringO 4 the second end difference 7; Be screwed in the nut 1 on snap bolt 2; And be set in the spacer 5 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; Push the through-hole wall gluing, sealing of 4 realizations of O RunddichtringO and workpiece 10 by screwing nut 1.
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 walls is provided with an annular flange that can be overlapped on the through hole end face of workpiece 10, can realize the restriction that sealing device hermetic unit is put into lead to the hole site axial depth.
Structure of the present invention 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 needs sealing, can easily put into through hole.When O type circle arrives in hole behind appropriate location, grip stop gripping member fastening nut with hand, make the extrusion of O RunddichtringO, external diameter swell, fits tightly with through-hole wall the sealing realizing through hole.After having sealed test and completing, then unscrew nut, O RunddichtringO is returned to original position, and device can easily exit through hole, and whole process is to through hole hole wall not damaged.The in the situation that the present invention being limited in spatial position, the aperture of through hole is directly sealed, the mounting or dismounting of whole device are convenient, and sealing is reliable, can Reusability, operate simple and easy.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
