Abstract
The utility model relates to a side-wall automatic negative pressure sealable tank. The utility model is characterized in that a side wall of a tank cover is provided with a groove, and the inner part of the groove is movably embedded with a one-way ventilating valve. The one-way ventilating valve is composed of a piano type sealing pressing block, a sealing air plug buckle and a reset compressed spring, wherein the bottom part of the piano type sealing pressing block is fixed with a hollow guide rod. The piano type sealing pressing block penetrates through a ventilating hole at the center of arranged at the bottom of the groove via the hollow guide rod, wherein the sealing air plug buckle is fixedly connected with the hollow guide rod. When the tank cover is pressed towards a tank body, the piano type sealing pressing block is pressed inwards and the sealing pressing block and the hollow guide rod drive the sealing air plug buckle to displace inwards. The air plug buckle eliminates the sealing on the ventilating hole at the bottom of the groove and the surrounding side wall of the groove, and the air in the tank can be exhausted outwards via the ventilating hole. When the sealing pressing block is loosened, the sealing pressing block is reset under the action of the compressed spring. The ventilating hole at the bottom of the groove and the surrounding side wall of the groove are sealed by the sealing air plug buckle again. When the tank cover is needed to be opened without pressing the sealing pressing block, the inner cavity of the tank body is in a negative pressure state and then the tank cover can not be easily opened, which facilitates keeping the sealing effect. Compared with the prior art, the utility model has the advantages of simpler and more reasonable structure, faster and more convenient assemblage and use and very ideal sealing effect.
Description
Technical field
The utility model relates to a kind of airtight container, a kind of specifically side wall type automatic negative pressure sealing jar.
Background technology
The airtight container jar is of a great variety, but existing sealable tank all is to cooperate (have or screw togather by screw thread) with the tight socket of tank body opening by cover, article in the jar and outside air are intercepted to reach sealing purpose, this the most common also be that the most original hermetically-sealed construction exists a lot of problems: seal degree is not ideal enough, outside air infiltrates in the jar easily, and is fashionable by the cover cover at tank body in addition, not only a jar interior air fails to discharge, partly be compressed in the jar on the contrary, cause sealing effectiveness poor.In order to overcome above-mentioned defective, China Patent No. is that 95246337.7 " a kind of vacuum seal jar " and another patent No. are that 97223830.1 " vacuum seal jar " all done very big improvement to sealing effectiveness, but above-mentioned two hermetically-sealed constructions that patent adopted are all comparatively complicated, as above-mentioned first kind vacuum seal jar, its hermetically-sealed construction is by placing a check valve and a supporting cylinder barrel thereof on jar central seam through hole to constitute, wherein check valve is by spool, valve gap constitutes, valve gap is actively socketed on the guide rod of spool, spool also is provided with boss and cooperates with the seam through hole of cover, wherein cylinder barrel is again by cylinder body, parts such as piston rod and piston combine, the sealable tank of this patent will could be extracted jar interior gas out and reach certain vacuum seal effect in use through the interoperation of cylinder barrel and check valve, and for example above-mentioned second kind vacuum seal jar, its hermetically-sealed construction also is to place the cover central top, and used parts comprise the seal cover cap that is installed on the lid, exhaust flange, vent plug, composition such as seal ring and pump bowl thereof.Though the airtight container of above-mentioned two patents has certain vacuum sealing function effect, used parts are many, complex structure, produce trouble is installed also, and behind the sealing member senile abrasion, also be difficult to guarantee permanent vacuum seal, extraneous air infiltrates in the jar easily.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thus design a kind of simple and practical, assembling easily, side wall type automatic negative pressure sealing jar easy to use.
The utility model is realized with following technical scheme: this negative pressure sealing jar still comprises tank body and cover, it is characterized in that being provided with a groove at the sidewall of cover, bottom portion of groove central authorities offer an air extractor vent, activity is embedded a unidirectional connection for bbreather pipe is installed in groove, this unidirectional connection for bbreather pipe is to seal briquetting by the piano type that a valve body is used, play sealing vent plug that spool uses and buckle and rise stage clip (pressure spring) composition of the usefulness that resets, wherein: the bottom that piano type is sealed briquetting has been fixed with the hollow guide rod that valve rod is used, and be installed in the air extractor vent of bottom portion of groove by hollow guide rod activity (wearing), wherein play the sealing vent plug that spool uses and buckle captive joint (socket) on hollow guide rod, when desiring to open and close operation, with cover the time toward the outer bead pressing (fit) of tank body, inwardly push piano type with the finger that grasps cover and seal briquetting, sealing briquetting drives sealing vent plug together with its hollow guide rod and buckles and move inward (displacement), vent plug is buckled and is removed bottom portion of groove air extractor vent and the sealing of cell wall all around thereof, air in jar will pass through the outside exhaust of this air extractor vent, after cover is put in place by pressing, loosen piano type and seal briquetting, seal briquetting and under the effect of stage clip elastic force, reset, the bottom portion of groove air extractor vent and all around the sealed again vent plug of cell wall buckle sealing.When piano type not being sealed that briquetting is inwardly pushed and will open cover the time, tank inner chamber can be in (or being tending towards) negative pressure state trend, make cover be difficult at will be opened easily, thereby the sealing effectiveness that can keep sealable tank, and in the time will opening cover, need only inwardly cover can be opened easily by the pressure seal mouth briquetting.
In the above-mentioned technical solution, the lateral surface design of sealing briquetting in described piano type causes few assisted ventilation slotted eye, helps more smooth and easy export-oriented exhaust when the pressing cover.
In the above-mentioned technical solution, seal the bottom (four angles) of briquetting in described piano type and also can design the backstop pin that leads and locate usefulness, backstop foot length 1 should be shorter than the length L of hollow guide rod, the effect of design backstop pin is inwardly to push sealing briquetting smoothly, and can control and push distance.
In the above-mentioned technical solution,, and can collude mutually that overlap joint cooperates with the jag shape elasticity on the mounting rod that plastic cement system sealing vent plug is buckled is protruding at the described draw-in groove that connects symmetry before and after on the hollow guide rod that the sealing vent plug buckles there being design that is used for fixing.
In above-mentioned technical solution, the outside face that described piano type is sealed briquetting is to make the geomery that matches with cover sidewall notches outer degree of lip-rounding shape, and also can further make and the corresponding to arcuate structure of cover circular arc sidewall.
In above-mentioned technical solution, the air extractor vent of described cover sidewall notches bottom center is the structure (as being the air extractor vent of making " cross " shape ventilating groove hole) that is designed to have at least an assisted ventilation slotted eye.
Compare with the sealable tank of prior art, structure of the present utility model is advantages of simple more, and assembling is used more convenient and quick, and sealing effectiveness is also very good.
