Embodiment Construction

[0024] The following is attached Figure 1~4 The present invention is described further:

[0025] Airbags can be divided into external airbags and built-in airbags according to the location of the airbags.

[0026] 1) Ensure the pressure balance inside and outside the sealed case

[0027] refer to figure 1 and figure 2 , comprising a sealed chassis 1 and an airbag 2, a ventilation pipeline 3 that traverses the casing of the chassis 1 and connects the inner cavity of the chassis 1 with the external environment outside the chassis 1 is provided in the casing of the chassis 1, said The reserved interface on the airbag 2 is connected to one end of the ventilation pipeline 3. The airbag 2 is in the shape of a long strip box, and a wing protrudes from each of the four corners of the airbag 2. The airbag 2 passes through the wing. The sheet is fixed on the inner wall of the cabinet 1 or the airbag 2 is fixed on the outer wall of the cabinet 1 .

[0028] The air bag 2 adjusts th...

Abstract

The invention discloses a sealing cabinet capable of balancing pressure in a self-manner, which is mainly used for guaranteeing to balance the pressure inside and outside the sealing cabinet, isolating the gas exchange inside and outside of the cabinet and protecting the internal members. The part of the prior art usually adopts a sealing cabinet mode, and when the device is in a live working condition in the high temperature environment or in the low temperature environment, an atmosphere pressure difference is generated between the inside and the outside of the sealing cabinet, so that the strength of the sealing cabinet and the pressure resistance levels of the film button, the liquid crystal display or other members are needed to be improved. The sealing cabinet disclosed by the invention employs a combination mode of an air bag to cooperating with a vent pipeline, and integrates the balance of the inside and the outside pressure of the sealing cabinet, and utilizes the temperature to change the pressure. The pressure acts on the gas and then enables the air bag to automatically inflate and deflate, which can automatically adjust the air pressure of the inside and outside of the sealing cabinet. The sealing cabinet which is capable of balancing pressure in the self-manner and is provided with a specially-produced air bag is characterized by sealing and waterproof, electromagnetic shielding, simple structure, and good versatility.

Description

technical field [0001] The invention belongs to the field of sealed chassis equipment, and in particular relates to a self-balancing pressure sealed chassis, which is mainly used to ensure the pressure balance inside and outside the sealed chassis, and at the same time isolate the gas exchange inside and outside the chassis, and prevent the wet and harmful gas from corroding and damaging the circuit board. Components, and play a protective role on membrane buttons, LCD screens, etc. Background technique [0002] At present, in order to improve environmental adaptability and enhance the performance of resistance to humidity and heat, mold, salt spray, and rain, some domestic communication equipment generally adopts a sealed chassis. When a communication device using a sealed chassis is powered on in a high-temperature or low-temperature environment, there will be a difference in atmospheric pressure between the inside and outside of the sealed chassis. The heat generated by ...
