Description

Positive pressure explosion-proof cabinet

technical field

The utility model relates to the field of explosion-proof cabinets, in particular to a positive pressure explosion-proof cabinet.

Background technique

At present, the positive pressure electrical control cabinet in the explosion-proof industry adopts the bolt 7 connection method between the cabinet body 1 and the door panel 2 to achieve the sealing effect, so as to ensure the slight positive pressure inside the cabinet body 1 during normal operation. Its sealing structure is shown in Figure 1. This structure increases the difficulty of the production process both in the sheet metal production process and the cabinet assembly process, reduces production efficiency, and is inconvenient for later maintenance of the equipment; the opening and closing of the door panel 2 is inconvenient; in addition, the complex structure also increases the cost of the product .

Utility model content

Purpose of the utility model: Aiming at the problems existing in the prior art, the utility model provides a positive pressure explosion-proof cabinet, which can reduce the difficulty of opening and closing the door panel and facilitate installation and maintenance on the basis of ensuring a slightly positive pressure environment inside the cabinet.

Technical solution: The utility model provides a positive pressure explosion-proof cabinet, including a cabinet body, a door panel, a lock bar, a lock buckle and a sealing strip, the cabinet body has a bent edge, and the lock bar is fixed on the edge of the door panel , and the handle of the lock lever is located on the outside of the door panel, the rod of the lock lever is located on the inside of the door panel, the sealing strip is fixed on the inside of the door panel, and the lock catch is fixed on the bending edge After the cabinet body is locked with the door panel, the rod is nested and locked with the lock buckle, and the other end of the bent edge is tightly pressed against the sealing strip.

Preferably, the lock bar is fixed on the door panel by a clip spring, and the clip spring is located inside the door panel.

Preferably, the bending edge is a right-angle bending edge. The right-angle bent edge is convenient for fixing the buckle, and it is convenient for pressing the sealing strip.

Further, the edge of the door panel has a hem. The design of the folding edge makes the seamless connection between the door panel and the cabinet body seen from the appearance of the explosion-proof cabinet, which is more beautiful.

Preferably, the folded edge is a right-angle folded edge. The right-angle folding edge makes the outer surface between the door panel and the cabinet body flush, which is more beautiful.

Beneficial effects: the cabinet body and the door panel in the utility model are fixed through the nested locking of the lock rod and the lock buckle, and then fixed by pressing between the bending edge of the cabinet body and the sealing strip, so that the inside of the cabinet can be kept slightly Positive pressure environment, when it is necessary to open the door panel or lock it with the cabinet body, it can be realized by gently rotating the handle of the lock lever. Compared with the bolt connection in the prior art, it can ensure the slight positive pressure environment in the cabinet On the basis of reducing the difficulty of opening and closing the door panel, it is convenient for installation and maintenance.

detailed description

Below in conjunction with accompanying drawing, the utility model is introduced in detail.

This embodiment provides a positive pressure explosion-proof cabinet, as shown in Figures 2 to 5. It has a right-angled bending edge 11, and the lock catch 4 is fixed on one side of the bending edge 11. The locking lever 3 is composed of a handle 31 and a rod 32. The locking lever 3 passes through the edge of the door panel 2 and is fixed on the door panel 2 through a snap spring 6. , and the handle 31 is located on the outside of the door panel 2, and the rod 32 is located on the inside of the door panel 2. For the sake of aesthetics, a right-angled hem 21 is provided on the edge of the door panel 2, and the sealing strip 5 is fixed on the inside of the door panel 2. When the body 1 is locked, push the handle 31 to insert the rod 32 of the lock rod 3 into the lock 4 and rotate and lock it. Sealing, so that a slight positive pressure environment is formed in the cabinet body 1. When the door panel 2 needs to be opened, just rotate the handle 31 in the opposite direction.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly, and not to limit the protection scope of the utility model. All equivalent transformations or modifications made according to the spirit of the utility model shall fall within the protection scope of the utility model.
