Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.

As shown in fig. 1-2, an airtightness testing device comprises bottle bodies 5, and further comprises a main accommodating box 1 and independent cavities 15 arranged in the main accommodating box 1 in an array manner for accommodating a plurality of bottle bodies 5, wherein a sealing plate 3 is arranged at the top of the main accommodating box 1 in a sliding manner, the sealing plate 3 is driven to seal the independent cavities 15 simultaneously, a liquid sump 11 is arranged at the bottom of the main accommodating box 1, the independent cavities 15 are communicated with the liquid sump 11 through bent pipes 2 arranged at the bottoms of the independent cavities 15, and the first end of each bent pipe 2 is positioned below the liquid level in the liquid sump 11. Through a plurality of independent chambeies 15 that the main 1 interior array of holding box set up, can place a plurality of bottle bodies 5 simultaneously in independent chamber 15 and detect, the shrouding 3 that utilizes the main top of holding box 1 is driven and is closed a plurality of independent chamber 15 simultaneously, thereby make independent chamber 15 form inclosed cavity, if bottle body 5 leaks gas this moment, then the gas of leaking is discharged in the liquid storehouse 11 through return bend 2, because of the first end of return bend 2 is located below the liquid level in the liquid storehouse 11, consequently can the bleb in the liquid storehouse 11, thereby be convenient for the staff judges which bottle body 5 gas leakage, thereby realized carrying out the gas tightness under the condition of not entrying to a plurality of bottle bodies 5 and detecting.

Specifically, the sealing plate 3 in the above technical solution is driven to seal the plurality of single cavities 15, and the driven mode may be pushing by a hydraulic cylinder, or gear matching with a motor and steel rope pulling; or may be driven in a manner known to those skilled in the art.

As shown in fig. 1, as the utility model discloses further provide a technical scheme, in order to make that shrouding 3 can be accurate hold case 1 to main sealing, main top of holding case 1 has seted up a plurality of guide slots 17, and a plurality of guide pillars 32 through the setting of shrouding 3 bottom slide respectively and set up in a plurality of guide slots 17 to accurate messenger shrouding 3 seals the open-top that mainly holds case 1.

Further, in order to make shrouding 3 push down when main case 1 that holds, can hold case 1 to main and carry out better sealing, the side channel 16 has been seted up to the main top case mouth that holds case 1, and the bottom of shrouding 3 is provided with bellying 31, and when shrouding 3 was driven and is pushed down, and this moment and bellying 31 laminate in the bottom of side channel 16 to hold case 1 to main and carry out better sealing.

Further, in order to make things convenient for quick place bottle body 5 in only chamber 15, the symmetry is provided with curved surface side platform 14 in only chamber 15 respectively, place in only chamber 15 through bottle body 5, bottle body 5 slides along curved surface side platform 14 this moment, and finally fall to the rack 13 that sets up respectively between two curved surface side platforms 14, when utilizing rack 13 to support bottle body 5, can avoid bottle body 5 to block up the gas outlet of only chamber 15 bottom simultaneously, thereby make the gas of bottle body 5 leakage discharge to liquid storehouse 11 through return bend 2.

Specifically, in order to observe the bubbles generated by the bent pipe 2, one side wall of the liquid tank 11 is a transparent tempered glass plate 12, and the transparent tempered glass plate 12 can be used for clearing the bubbles generated by each bent pipe 2.

Further, since water is stored in the liquid tank 11, the main storage tank 1 is made of a stainless steel plate in order to reduce the problem of rusting of the main storage tank 1.

Further, in order to strengthen the sealed effect of shrouding 3 to every single chamber 15, there is sealed rubber circle 4 bottom and single 15 accent one side in chamber of limit groove 16 respectively fixed mounting, when shrouding 3 pushes down in main containing box 1, every single chamber 15 is independent and sealed respectively this moment to every does not influence each other between the chamber 15 alone.

Furthermore, the bent pipe 2 is a glass pipe, and the inner diameter of the glass pipe is 0.2-0.5mm, so that the gas in the single cavity 15 is accelerated to be discharged into the liquid bin 11 by reducing the pipe diameter of the glass pipe as much as possible.

Specifically, return bend 2 is the L type to the first end that makes return bend 2 can be close to transparent toughened glass board 12, so that the staff observes the end of giving vent to anger of return bend 2.

More specifically, because bottle body 5 can produce certain striking when falling to rack 13 on, in order to avoid damaging the bottom of bottle body 5 when striking, the activity is provided with the cotton pad of buffering respectively on the rack 13, and the cotton pad of buffering has fine gas permeability simultaneously to make the gas that bottle body 5 leaked can see through the cotton pad of buffering.

The working principle is as follows: through placing a plurality of bottle bodies 5 in only chamber 15, utilize the main shrouding 3 that holds the top of case 1 to be driven and seal a plurality of chamber 15 alone simultaneously, thereby make alone chamber 15 and form inclosed cavity respectively, if bottle body 5 leaks gas this moment, then the gas of leakage passes through return bend 2 and discharges in the liquid storehouse 11, because of the first end of return bend 2 is located below the liquid level in liquid storehouse 11, consequently can form the bubble in the liquid storehouse 11, thereby be convenient for the staff judges which bottle body 5 leaks gas, through setting up a plurality of chamber 15 alone can avoid bottle body 5 because of soaking water later stage needs the stoving scheduling problem.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
