Abstract
The utility model relates to an inside and outside air pressure equalizer of an environment climate box. The inside and outside air pressure equalizer of the environment climate box is characterized by comprising an equalizer barrel body, an air inlet cap, an air outlet cap and a vent hole, wherein an air inlet and an air outlet are formed in two ends of the equalizer barrel body respectively, the air inlet cap is arranged at the inner side of the air inlet through hinge overturning, the air outer cap is arranged at the outer side of the air inlet through hinge overturning, and the vent hole is formed in the middle of the equalizer barrel body. The inside and outside air pressure equalizer of the environment climate box has a scientific and reasonable structure design, has the good box body sealing property, is free from test sample damage, can adjust the inside and outside air pressure to be equalized and is easy to realize, and therefore, the inside and outside air pressure equalizer has the high innovativeness.
Description
Technical field
The utility model belongs to packaging test apparatus field, particularly a kind of amblent air temperature case inside and outside air pressure balance device.
Background technology
Amblent air temperature case is a kind of cold and hot thermostatic equipment of high accuracy with illumination, humidification function, for user provides a desirable artificial climate experimental enviroment.At packaging field, can simulate local weather and test the performance of packing case or packing container, thereby reach certain transport, storage demand.But, in the process of testing at environment for use case, it is found that, amblent air temperature case is in the time carrying out high low temperature and damp heat test, and box house air pressure can be greater than or less than standard pressure, can make equipment expand when internal pressure is excessive, damages the sealing of casing; And hyperbaric environment also can be damaged to some extent to the sample of testing.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide that a kind of design science is reasonable, box body tightness good, not destructive test sample, can regulate inside and outside air pressure balance, be easy to the amblent air temperature case inside and outside air pressure balance device realized.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of amblent air temperature case inside and outside air pressure balance device, it is characterized in that: formed by balancer ladle body, air inlet cover, air-out lid and air vent, two ends at balancer ladle body are shaped with respectively air inlet and air outlet, overturn air inlet cover be installed by hinge in inner side at air inlet, overturn capping be installed out by hinge in outside at air inlet, described air vent is formed on the middle part of balancer ladle body.
Advantage of the present utility model and good effect are:
1. this amblent air temperature case inside and outside air pressure balance device, when use, is connected air vent with amblent air temperature box body, when casing internal pressure is during higher than pressure outside, air-out lid is opened automatically; When casing internal pressure is during lower than pressure outside, air inlet cover is opened automatically.Realize thus supplementing of climate box internal gas, finally reach the effect of test air pressure internal and external equilibrium, avoided because of the uneven amblent air temperature case causing of air pressure and test specimen damage problem.
2. the utility model scientific structure design is reasonable, have advantages of box body tightness good, not destructive test sample, can regulate inside and outside air pressure balance, be easy to realize, be a kind of amblent air temperature case inside and outside air pressure balance device with higher innovation.

Fig. 2 is the cutaway view of Fig. 1.
Description of reference numerals:
1-balancer ladle body, 2-air vent, 3-air-out lid, 4-hinge, 5-air inlet, 6-air inlet cover, 7-air outlet.
Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, the utility model is described in further detail.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of amblent air temperature case inside and outside air pressure balance device, its innovation is: be made up of balancer ladle body 1, air inlet cover 6, air-out lid 3 and air vent 2, be shaped with respectively air inlet 5 and air outlet 7 at the two ends of balancer ladle body, inner side at air inlet is provided with air inlet cover by hinge 4 upsets, overturn capping be installed out by hinge in outside at air inlet, air vent is formed on the middle part of balancer ladle body.
When use, air vent is connected with amblent air temperature box body, when casing internal pressure is during higher than pressure outside, air-out lid is opened automatically; When casing internal pressure is during lower than pressure outside, air inlet cover is opened automatically.Realize thus supplementing of climate box internal gas, finally reach the effect of test air pressure internal and external equilibrium.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: not departing from the spirit and scope of the utility model and claims, various replacements, variation and amendment are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
