Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning box units, in particular to a box assembly suitable for positive and negative pressure working conditions. Background Art

[0002] Whether they are frame structures or frameless structures, the air conditioning box units currently on the market all install the box panels from the outside in. This installation method works very well under negative pressure conditions because, under negative pressure conditions, the external air pressure is greater than that inside the box, forming an inward pressure difference. This pressure difference helps the box panels fit tightly with the box body, allowing the box panels installed from the outside in to better resist the pressure of the external air, thereby achieving a better sealing effect. However, when encountering positive pressure conditions, under positive pressure conditions, the air pressure inside the box body is greater than that outside, forming an outward pressure difference. This pressure difference makes the box panels more susceptible to outward thrust, resulting in an increase in the gap between the box panels and the box body, reducing the sealing effect, and can only be tightened by screws. The greater the pressure, the worse the tightening and sealing effect. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 4 , a box assembly suitable for positive and negative pressure working conditions, including an outer plate assembly 1, a positive pressure section connecting frame assembly 2, a negative pressure section connecting frame assembly 3 and an intermediate connecting frame assembly 7;

[0023] The outer panel assembly 1 comprises a plurality of outer panels with fixing members mounted on one side at both ends;

[0024] The positive pressure section connection frame assembly 2 includes a plurality of positive pressure section connection frames with L-shaped front and side sections;

[0025] The negative pressure section connection frame assembly 3 includes a plurality of negative pressure section connection frames with rectangular front and side sections;

[0026] The intermediate connecting frame assembly 7 includes a plurality of intermediate connecting frames with rectangular front and side sections;

[0027] The surfaces of the positive-pressure section connecting frame, the negative-pressure section connecting frame and the intermediate connecting frame are all provided with mounting holes matched with the fixing parts.

[0028] When the device is in use, it can be assembled into a box form suitable for positive pressure conditions or negative pressure conditions by selecting corresponding components according to the working conditions. For example, in positive pressure conditions, one side of the outer panel mounting fixture faces inward and is embedded in the inner side of the positive pressure section connecting frame, and the connection is completed through the fixture and the mounting hole. The position of the middle section is achieved by embedding the middle connecting frame into the groove formed by the corresponding two fixtures and the outer panel. In negative pressure conditions, one side of the outer panel mounting fixture faces outward, so that the negative pressure section connecting frame is placed in the cavity formed by the corresponding two fixtures and the outer panel, and the connection is completed through the fixture and the mounting hole. The position of the middle section is achieved by embedding the middle connecting frame into the groove formed by the corresponding two fixtures and the outer panel, which solves the problem that the current box structure can only be used for negative pressure conditions, and the tightness and sealing effect are poor in positive pressure conditions.

[0029] In this embodiment, the positive pressure section connecting frame, the negative pressure section connecting frame and the intermediate connecting frame all include a frame outer shell and a foam body 6 inside the frame outer shell, and the frame outer shell is formed by combining foam boards.

[0030] In this embodiment, the fixing member includes a nail sleeve 4 installed on the side of the outer panel and a screw 5 provided on the nail sleeve 4, and the connection with the foam body 6 is completed by the screw 5.

[0031] In this embodiment, the surface of the nail sleeve 4 is provided with double-sided adhesive PE and sealing soft glue.
