Abstract
The utility model provides a kind of vacuum sealing device, including the fastener and sealing bolt being oppositely arranged, the strip groove that one section of cross section is semicircle shape is provided on the lateral surface of the fastener right part, the strip groove that one section of cross section is semicircle shape is provided on the medial surface of the sealing bolt left part, two strip grooves are corresponding and one section of synthesis is cylindric, and the cylindrical pin being adapted is welded in the strip groove of the fastener.A kind of vacuum sealing device provided by the utility model solve the problems, such as vacuum sealing device due to thread seal is tightened and compressing member is as fastening nut rotates, while efficiently reduces the problem of seal fitting is more, and later maintenance workload increases.
Description
Technical field
The utility model is related to sealing devices, and in particular to a kind of vacuum sealing device.
Background technology
Traditional sealing element is one stainless steel ring of addition between compressing member and silicon rubber, to ensure in clamp nut pressure
During tight silicon rubber, due to compressing member rotation, silicon rubber will not rotate therewith.But this mode is due to user's later stage
When safeguarding dismounting, stainless steel ring easily comes off loss, usually can not be used again, influences the production of client.
Utility model content
For the drawbacks described above and problem of the prior art, technical problem to be solved in the utility model is vacuum sealing dress
Put due to thread seal is tightened and compressing member with fastening nut rotate the problem of.
In order to achieve the above object, the utility model provides following technical solution：
A kind of vacuum sealing device, including the fastener and sealing bolt being oppositely arranged, outside the fastener right part
The strip groove that one section of cross section is semicircle shape is provided on side, one section of horizontal stroke is provided on the medial surface of the sealing bolt left part
Section is the strip groove of semicircle shape, and two strip grooves are corresponding and synthesize one section of cylindric, strip of the fastener
The cylindrical pin being adapted is welded in groove.
In above-mentioned technical proposal, a diameter of 3mm of the pin, length 5mm, the right end of the pin and fastener
Right side is concordant.
A kind of vacuum sealing device provided by the utility model solve vacuum sealing device since thread seal is tightened and
Compressing member with fastening nut rotate the problem of, while efficiently reduce that seal fitting is more, and later maintenance workload increases again
Problem.

Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model is clearly and completely described,
Obviously, the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Based on this practicality
Embodiment in novel, the every other reality that those of ordinary skill in the art are obtained without creative efforts
Example is applied, shall fall within the protection scope of the present invention.
As shown in Figs. 1-5, include the fastener that is oppositely arranged and close as a kind of vacuum sealing device shown in embodiment
Bolt is sealed, the strip groove that one section of cross section is semicircle shape, sealing bolt left part are provided on the lateral surface of fastener right part
Medial surface on be provided with one section of cross section be semicircle shape strip groove, two strip grooves it is corresponding and also synthesis one section of cylinder
Shape is welded with the cylindrical pin being adapted in the strip groove of fastener.Efficiently solve the problems, such as sealing locking, simultaneously
Pin will not come off because of dismounting, reduce the workload of client's installation maintenance, ensure that the work continuity in later stage.
A diameter of 3mm of pin in present embodiment, length 5mm, the right end of pin are concordant with the right side of fastener.
The above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, in the technical scope that any one skilled in the art discloses in the utility model, variation can be readily occurred in
Or replace, it should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be described with power
Subject to the protection domain of profit requirement.
