Including for installing vacuum cavity that is fixed and placing paster, the guide holder installed in vacuum cavity side both sides, installed in true
The pressure release component of cavity body side.A plurality of pressure holes are set in vacuum cavity side wall, are provided with each pressure hole
A plurality of binding posts.Due to easily losing heart between the pressure hole and binding post, if vacuum cavity needs sealing so that sealing
Time is long, causes the sealing of whole vacuum cavity poor.Because each pressure hole needs on vacuum chamber are mutually right
The binding post answered realizes sealing function so that multiple binding posts is needed, so as to cause to increase processing cost.
【Utility model content】
In view of this, technical problem to be solved in the utility model is to provide a kind of with sealing is improved, and reduces and adds
Work cost, there is the vacuum sealing device of decompression.
Solving above-mentioned technical problem for this, the technical scheme in the utility model uses a kind of vacuum sealing device, its
Including vacuum cavity, the guide holder installed in vacuum cavity both sides, the pressure release component on the side arm of vacuum cavity one, installation
Vacuum meter on another side arm of vacuum cavity, it is provided with a side wall of the vacuum cavity for improving sealing and decompression
The vacuum seal structure of function.
Further limited according to technical characteristics, the vacuum cavity includes cavity drain pan, on cavity drain pan
The cover plate in face, the sealing strip between cover plate surrounding and cavity drain pan upper end inwall surrounding.
Further limited according to technical characteristics, the vacuum seal structure includes being arranged in vacuum cavity side wall
Strip groove, a plurality of interior pressure holes being arranged inside strip groove, the bar shaped sealing plate inside strip groove, if
The sealing ring being placed between interior pressure hole and bar shaped sealing plate.
Further limit, be provided with the bar shaped sealing plate a plurality of mutual with interior pressure hole according to technical characteristics
Corresponding outer pressure hole.
Further limited according to technical characteristics, the sealing ring is made up of the ring washer of indent evagination.
The utility model advantageous effects：It is used to improve sealing and subtracts because is provided with a side wall of the vacuum chamber
The vacuum seal structure of function is pressed, the vacuum seal structure includes the strip groove being arranged in vacuum cavity side wall, set
A plurality of interior pressure holes, the bar shaped sealing plate inside strip groove inside the strip groove, be arranged at interior pressure hole with
Sealing ring between bar shaped sealing plate.Because the sealing ring is made up of the ring washer of indent evagination.It is described during work
Sealing ring back side precision is fitted in interior air pressure internal surface of hole, and sealing ring is positive together with the accurate fitting of outer pressure hole so that outer
The air pressure on boundary be can only enter in vacuum cavity, and the air pressure of vacuum cavity can not be to leaking so that positive and negative air-pressure is kept apart, and is prevented
Positive and negative air-pressure is mixed, and reaches decompression.At the same time, it is also prevented from the air pressure inside vacuum cavity to leak, so as to improve
The sealing property of vacuum cavity.Compared with binding post in the prior art, the utility model also has described vacuum seal structure
There is the advantages of reducing processing cost.
With reference to the accompanying drawings and examples, the technical solution of the utility model is described in further detail.
【Brief description of the drawings】
Fig. 1 is the stereogram of vacuum sealing device in the utility model；
Fig. 2 is the three-dimensional exploded view of vacuum sealing device in the utility model；
【Embodiment】
In order that technical problem to be solved in the utility model, technical scheme and beneficial effect are clearer, clear, with
Under in conjunction with the accompanying drawings and embodiments, the utility model is further elaborated.It is it should be appreciated that described herein specific real
Example is applied only to explain the utility model, is not used to limit the utility model.
It refer to shown in Fig. 1 and Fig. 2, illustrate a kind of vacuum sealing device with reference to embodiment, it includes vacuum cavity,
Guide holder 1 installed in vacuum cavity both sides, the pressure release component 2 on the side arm of vacuum cavity one, installed in vacuum cavity
Vacuum meter 3 on another side arm, it is provided with a side wall of the vacuum cavity for improving the true of sealing and decompression
Empty sealing structure.
The vacuum cavity includes cavity drain pan 4, the cover plate 5 above cavity drain pan 4, installed in the surrounding of cover plate 5
With the sealing strip 6 between the upper end inwall surrounding of cavity drain pan 4.The vacuum seal structure includes being arranged in vacuum cavity side wall
Strip groove 7, be arranged at a plurality of interior pressure holes 8 in the inside of strip groove 7, the bar shaped installed in strip groove 7 inside seals
Plate 9, the sealing ring 10 being arranged between interior pressure hole 8 and bar shaped sealing plate 9.It is provided with the bar shaped sealing plate 9 a plurality of
With interior pressure hole 8 mutually corresponding outer pressure hole 11.The sealing ring 10 is made up of the ring washer of indent evagination.
During installation, described bar shaped sealing plate 9 is arranged on inside strip groove 7, and the described back part of sealing ring 10 is split
