Description

A fastening structure for electrical equipment cabinet doors

technical field

The invention relates to a fastening structure for cabinet doors of electrical equipment, belonging to the technical field of electrical equipment.

Background technique

General electrical equipment cabinets are necessary for various laboratories, test stations, and testing laboratories. This type of electrical equipment cabinet is equipped with a fastening mechanism on the cabinet door for test safety.

At present, the existing electrical equipment cabinets are equipped with traditional hook-type structures or card-type mechanisms.

The shortcoming of this mechanism is that fastening is unreliable, it is not fastened when it should be fastened, and it cannot be opened when it should be opened.

The doors of electrical equipment cabinets on ships often need to be opened frequently to operate internal equipment, or to quickly maintain and repair internal equipment. At the same time, the cabinet door needs to have shock and vibration resistance and shell protection.

Contents of the invention

The object of the present invention is to provide a fastening structure for electrical equipment cabinet doors, which can quickly open and quickly fasten the electrical equipment cabinet doors to meet the needs of the electrical equipment cabinet doors on ships that need to be frequently opened to operate the interior Equipment, or internal equipment that needs to be quickly maintained and repaired, and the cabinet door needs to have shock and vibration resistance and shell protection.

In order to achieve the above object, the technical solution of the present invention is: the device includes a nail cap 1, a first gasket 2, a spring 3, a second gasket 4, a clip 5, and an Ω-shaped fixing piece 6.

Among them, the nail body is in the shape of a screw, the cap is in the shape of a cylinder, and the cylinder surface is rolled with patterns to increase the friction when twisting by hand. A slot is opened on the top for a slotted screwdriver to twist.

The nail head is flat-headed and columnar, and a guide groove is cut in the middle of the nail head end.

The nail head is flat-headed and columnar, and a guide groove is cut in the middle of the end of the nail head. With the deepening of the guide groove, the guide groove rotates 90 degrees clockwise, and there is a positioning concave gap above the end of the guide groove. The nail body A groove is cut out in the middle ring, and the clamp is clamped to limit the movement of the second gasket to the direction of the nail head. There is a spring between the first gasket and the second gasket, and the first gasket is under the action of the spring force and The nail cap clamps the cabinet door wall together, and the fixing seat is fixed to the cabinet body with two screws, and there is a hole in the middle that matches the nail body, and there is a steel rod placed horizontally in the hole.

The beneficial effect of the present invention is: since the cabinet door of the electrical equipment on the ship needs to be frequently opened to operate the internal equipment, or the internal equipment needs to be quickly maintained and repaired, and the cabinet door needs to have shock resistance and vibration resistance and shell protection function, therefore, It has certain economic benefits and is worth promoting and using.

The technical solutions of the present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments.

Description of drawings

Fig. 1 is a schematic diagram of the structure of the fastening structure used for electrical equipment cabinet doors of the present invention;

Fig. 2 is the schematic diagram of the fastening structure Ω-shaped fixing sheet for the electrical equipment cabinet door of the present invention;

Fig. 3 is a schematic diagram when the fastening structure for the electrical equipment cabinet door of the present invention is closed;

Detailed ways

Referring to FIG. 1 , it is a schematic diagram of the fastening structure used for electrical equipment cabinet doors according to the present invention.

As shown in the figure, the nail cap is in the shape of a cylinder, and the surface of the cylinder is rolled with patterns to increase the friction force when twisting by hand. There is a slot on the top for twisting by a slotted screwdriver.

Referring to FIG. 2 , it is a schematic diagram of the Ω-shaped fixing piece of the fastening structure used for electrical equipment cabinet doors according to the present invention.

As shown in the figure, rotate the nail body by 90 degrees by turning the nail cap (clockwise or counterclockwise), so that the upper and lower notches on the nail body can be rotated to the horizontal direction, so that the original horizontal shape of the nail body will be pushed up. Open the upper and lower wings of the Ω-shaped fixing piece, and under the action of the two wings of the Ω-shaped fixing piece and the elastic force of the spring, the nail body will be automatically ejected, thereby achieving the purpose of quickly opening the cabinet door.

Referring to FIG. 3 , it is a schematic diagram of the fastening structure for electrical equipment cabinet doors of the present invention when it is closed.

As shown in the figure, when the cabinet door is closed, the nail head of the nail body enters the hole in the middle of the fixing seat of the cabinet body, and the horizontally placed steel rod in the hole is inserted into the guide groove at the end of the nail head. Rotate the nail body clockwise, so that the horizontally placed steel rod goes deep into the nail body along with the guide groove.

Referring to FIG. 4 , it is a schematic diagram of the opening of the fastening structure for electrical equipment cabinet doors of the present invention.

As shown in the figure, when the cabinet door needs to be opened, it is only necessary to rotate the nail body 90 degrees counterclockwise by twisting the nail cap, so that the steel rod placed horizontally in the fixing seat will exit the nail body along the guide groove through the rotation of the nail body. So as to achieve the purpose of quickly opening the cabinet door.

Although the present invention has been described with reference to the above-mentioned embodiments, those of ordinary skill in the art should realize that the above-mentioned embodiments are only used to illustrate the present invention, and it should be understood that various changes and modifications can be made in a broad sense. There is no departure from the present invention, so it is not intended as a limitation to the present invention. As long as it is within the spirit of the present invention, changes and deformations to the above-mentioned embodiments will fall within the protection scope of the claims of the present invention.
