In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The utility model provides an automatically controlled box 1000 can improve control element's installation effectiveness. The embodiment of the utility model provides a to improve transformer 2000's installation effectiveness and exemplify the structure of automatically controlled box 1000.

As shown in fig. 1-12, an embodiment of the present invention provides an electrical control box 1000, wherein a cassette 1200 is fixedly disposed in a box body 1100 of the electrical control box 1000, the cassette 1200 includes a first clamping arm 1210 and a second clamping arm 1220 that are fixedly connected to each other, the first clamping arm 1210 and the second clamping arm 1220 are disposed opposite to each other and form a clamping groove 1230 for clamping a wing plate 2100 therebetween; notch 1231 aperture of draw-in groove 1230 can be adjusted, that is, the aperture of notch 1231 can increase or reduce as required, can make pterygoid lamina 2100 block smoothly to the draw-in groove 1230 when notch 1231 increases the state, can prevent pterygoid lamina 2100 from deviating from in draw-in groove 1230 when notch 1231 reduces the state.

The embodiment of the utility model provides an in, notch 1231 aperture adjustment can set up to initiative implementation, and the aperture of artificial active control notch 1231 promptly, when needs installation transformer 2000, the initiative is with notch 1231 aperture increase, and then goes into pterygoid lamina 2100 card to the draw-in groove 1230 in, after pterygoid lamina 2100 card goes into draw-in groove 1230 and targets in place, the initiative is reduced notch 1231 aperture to restriction pterygoid lamina 2100 deviates from draw-in groove 1230. In addition, can also set up notch 1231 aperture adjustment as passive implementation, when needs installation transformer 2000, pterygoid lamina 2100 struts notch 1231 and then makes notch 1231 aperture increase, and pterygoid lamina 2100 is gone into to draw-in groove 1230 and is put in place after, and notch 1231 aperture automatic recovery reduces in order to restrict pterygoid lamina 2100 to deviate from draw-in groove 1230.

Therefore, when the transformer 2000 is installed, the installation of the corresponding position of the wing plate 2100 can be completed only by clamping the wing plate 2100 into the clamping groove 1230, and the installation station space of the screwdriver is not required to be reserved for the structural arrangement of the clamping seat 1200, so that the installation efficiency is obviously improved, the installation space is also saved, and the structural compact design of the electronic control box 1000 is facilitated.

Specifically, the connection mode of cassette 1200 and box 1100 can adopt multiple forms, one is to block solid arm 1210 with first card and be connected with box 1100 fixed connection, another is to block solid arm 1220 with the second card and be connected with box 1100 fixed connection, the other is to block solid arm 1210 with the second card and be connected with box 1100 fixed connection simultaneously with first card and be fixed arm 1220, and then realize the fixed connection of cassette 1200 and box 1100, these several kinds of connection modes are all in the protection scope of the utility model.

The embodiment of the utility model provides an in, set notch 1231 aperture adjustment to passive implementation, it is specific, first card solid arm 1210 has elasticity, and when the installation transformer, pterygoid lamina 2100 props notch 1231 by oneself big until pterygoid lamina 2100 stretches into to draw-in groove 1230 and targets in place, and first card solid arm 1210 is located the position self return of notch 1231 position department and carries out spacingly at this position department to pterygoid lamina 2100, and then with pterygoid lamina 2100 card solid in draw-in groove 1231. It should be noted that, after the wing plate 2100 extends into the slot 1231 to a certain position, the end of the wing plate 2100 is located at the position of the notch 1231 along the depth direction of the slot 1231 (i.e. the moving direction of the wing plate 2100 into the slot 1231), because the first locking arm 1210 has elasticity, the notch 1231 has a clamping effect on the wing plate 2100 at the position, that is, the wing plate 2100 and the wall surface of the notch 1231 are in interference fit, and the interference range can be selected to be 0.3mm-1.0 mm.

It should be noted that the elasticity of the first locking arm 1210 means that the elasticity of at least the portion of the first locking arm 1210 located at the position of the notch 1231. In this embodiment, as shown in fig. 1 to 12, the first fastening arm 1210 is an integral structure and has elasticity, so as to adjust the opening of the notch 1231; although not shown, in addition to the above, the embodiment of the present invention may also provide other elastic structures only at the position of the notch 1231 of the first fastening arm 1210, for example, an elastic buckle (e.g., an elastic structure at the opening and closing position of the umbrella) is provided at the position of the notch 1231 of the first fastening arm 1210.

With reference to fig. 7-12, in the embodiment of the present invention, the position of the first fastening arm 1210 at the position of the notch 1231 has a limiting protrusion 1211, and the limiting protrusion 1211 extends toward the direction close to the second fastening arm 1220 and protrudes out of the inner wall of the first fastening arm 1210; after the wing plate 2100 is clamped in the slot 1230 in place, as shown in fig. 7, 8, 10 and 11, the lower end surface of the limiting protrusion 1211 abuts against the upper side wall of the wing plate 2100, so as to prevent the wing plate 2100 from being separated from the slot 1230, thereby limiting the position above the wing plate 2100; when the transformer 2000 needs to be detached from the electrical control box 1000, the first fastening arm 1210 is slightly pulled hard at the position of the notch 1231 to increase the opening of the notch 1231, so that the wing plate 2100 is separated from the clamping groove 1230, and the mounting and the detachment are convenient and labor-saving.
