Description

Air switch

Technical Field

The utility model relates to an air switch.

Background

At present, air switches are widely used, a plurality of air switches are generally arranged inside an air switch box at the same time, and the air switches are sealed in a box cover through the air switch box and a box cover arranged outside the air switch box. In the prior art, a box cover of an air switch box is hinged with limiting grooves on two sides of a groove on the box body through limiting blocks on two sides of the box cover, and the connecting mode is not firm and is easy to fall; and when changing or wiring the air switch in the box, the lid that lifts can't be fixed, can only increase the state that the staff opened and kept the lid this moment, has increased labour's use, leads to the use convenience poor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to the above-mentioned defect among the prior art, provide an air switch that box cover can keep the open mode.

In order to realize the purpose of the utility model, the utility model adopts the following technical scheme:

the utility model provides an air switch, includes box body, lid, set up the electric circuit in the box body, the twist grip of setting on the box body, one side of lid articulates on the box body, the lid can cover the twist grip around articulated department, be equipped with the spring that lets the lid keep the open mode between the articulated side of lid and the box body, the offside of the articulated side of lid is provided with first hook portion, be provided with the fastener on the box body, the fastener is including second hook portion, first, second hook portion hooks each other when the lid covers the twist grip.

Furthermore, the utility model discloses still provide following subsidiary technical scheme:

the hinged side of the box cover is hinged with the box body through a spring hinge, and the spring is arranged in the spring hinge.

The fastener further comprises a connecting rod and a button, one end of the connecting rod is connected with the box body, and the button and the second hook portion are respectively arranged on two sides of the other end of the connecting piece.

The hinged side and the opposite side of the box cover are perpendicular to the surface of the box body covered when the box cover covers the rotating handle.

The first hook part and the second hook part are laterally protruded on the box cover or the buckling piece, and the back-to-back hooked parts of the first hook part and the second hook part are arc surfaces.

Compared with the prior art, the utility model has the advantages that: the utility model discloses an air switch's lid is difficult to fall, and the convenience just can keep the open mode for a long time to open the lid, improves convenience and the security of its use.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the present invention, taken in conjunction with the accompanying drawings and the detailed description, is given in a non-limiting manner.

As shown in fig. 1, the air switch comprises a box body 1, a box cover 2, an electric circuit arranged in the box body, and a rotating handle 3 arranged on the box body, wherein one side of the box cover 2 is hinged on the box body 1, a spring for keeping the box cover in an open state is arranged between the hinged side of the box cover and the box body, and the hinged side opposite side and the cover body are fixed with each other when the box cover 2 covers the rotating handle 3.

The hinged side of the box cover 2 is hinged with the box body 1 through a spring hinge 4, and a spring 10 in the spring hinge 4 enables the box cover 2 to be kept in an open state when external force is not applied. As shown in fig. 3, a first hook 5 is provided to protrude outward at the opposite side of the hinge side of the box cover 2. The box body 1 is provided with a buckling piece 6, the buckling piece 6 comprises a connecting rod 7 with one end vertically connected with the box body 1, the two sides of the other end of the connecting rod 7 are respectively provided with a second hook part 8 and a button 9, wherein the second hook part 8 is arranged in a protruding mode towards the box cover 2, and the button 9 is arranged in a protruding mode in the opposite direction. In order to enable the first hook part 5 and the second hook part 8 to be hooked and flicked more smoothly, the hooked parts of the first hook part 5 and the second hook part 8 are set to be cambered surfaces. As shown in fig. 2, when the cover 2 is coupled to the side of the hinge 4 and the first hook 5 is provided, when the cover 1 covers the handle 3, the cover 2 is perpendicular to the covered side of the case 1, and the cover 2 is more easily coupled to the hinge 4 than a conventional cover.

The utility model discloses a lid 2 passes through spring hinge 4 to be installed on box body 1, opens lid 2 repeatedly also and is difficult to fall. When the box cover 2 covers the rotating handle 3, the first hook part 5 and the second hook part 8 are hooked with each other; when changing the components and parts in the box body 1 or when the wiring, press button 9 and drive second hook portion 8 and loosen, make first hook portion 5 break away from with second hook portion 8, lid 2 receives the elastic force effect to bounce, and lid 2 makes lid 2 keep the state of opening owing to the effort of spring in the spring hinge 4, convenient operation.
