Abstract

The utility model relates to a switch box. A box cover is provided with a protecting covering, one end of the protecting covering is hinged with the box cover, the other end of the protecting covering is provided with a straight hook which is vertical to the edge of the covering, and the edge of the straight hook is restricted of the position by the lower bottom edge of an elastic press-button on the box cover when in a closed position. The rotation center of the elastic press-button is lower than the lower bottom edge for restricting positions, and the elastic press-button is connected with the bottom of the box cover into a whole through two bevel edges. The utility model has the advantages of simple structure, less connecting fittings, easy and convenient closing and opening, beautiful appearance, etc. and is suitable for various switch boxes, especially for various cabinets, cases and boxes for electric appliances and other similar situations.

Description

Switch-box

The utility model relates to the casing that protective cover is housed on the case lid, and concrete is a kind of switch-box, is particularly suitable for being applied to distribution box and similar site thereof.

Various electrical equipment combinations need be installed in cabinet, case, the box, have case lid that it is sealed outside it, the operating knob of electrical equipment, switch etc. generally expose to outside the case lid, need it be covered with protective cover for reasons such as safety sometimes, for example a kind of light distribution box, its operating knob need to cover with transparent shield.Protective cover and case lid be connected with various ways, prior art exists part more, structure is numerous and diverse, uses deficiencies such as inconvenience.

The purpose of this utility model provides the switch-box that protective cover is housed on a kind of case lid, and the joint construction of its protective cover and case lid is reasonable, and is simple in structure, and part reduces, the closed unlatching conveniently easily.

Used technical scheme: switch-box of the present utility model, formed by casing and case lid,

A. on the case lid protective cover is housed, an end and the case lid of protective cover are hinged, and the other end has the straight hook of vertical flaring, and the crochet of this straight hook is spacing by the position-limited edge institute that goes to the bottom of the elastic button on the case lid when make position.

B. the center of rotation of elastic button is lower than its position-limited edge of going to the bottom, and its size makes that when the elastic button pressurized rotates its position-limited edge of going to the bottom moves simultaneously outside center of rotation, and its external shift quantity is greater than the crochet width of the straight hook of protective cover.

C. elastic button is connected with at the bottom of the case lid by two hypotenuses that point to the case lid inner chamber.

The connection elastic button of present technique and the hypotenuse of case lid system forms for twice by 135 ° of angle inverse bendings, and connecting hypotenuse in elastic button described in the preferred plan and bending is to make with the plastic monoblock pressure injection with case lid.

Switch-box of the present utility model, its protective cover has been realized intended purposes with being connected of case lid, have simple in structure, part is few, closed and open advantages such as easy and convenient, good looking appearance, be applicable to various switch cubicles, case, box and other similar site.

Now in conjunction with the accompanying drawings with preferred embodiment:

Fig. 1 is the embodiment that the utility model is applied to a kind of light distribution box.

Fig. 2 is the A-A cross section of Fig. 1.

Fig. 3 is the vertical view of Fig. 2, has only drawn some.

Fig. 4 is the oblique view of local parting of B-B, the C-C scope of Fig. 3.

Fig. 5 is the schematic diagram of the utility model in make position, local expression.

The same Fig. 5 of Fig. 6 shows the enable possition.

Switch-box of the present utility model is made up of casing 1, case lid 2 and is seen Fig. 1, electric appliance component 3 is housed in it, upper surface at case lid 2 is equipped with protective cover 4, one end of protective cover 4 is seen Fig. 2 with bearing pin 5 and case lid 2 are hinged, and protective cover can be upspring automatically with torsion spring 6, the end in addition of protective cover has the straight hook 7 of vertical flaring to be integral with protective cover, straight hook 7 has crochet 8, position to honest hook 7 on case lid 2 is provided with elastic button 9, this button is connected in the bottom surface of case lid by two hypotenuses 10 that point to the case lid inner chamber.In preferred plan, described hypotenuse 10 is to form by twice of 135 ° of forward and reverse bending of angle to see that Fig. 4, hypotenuse 10 can use riveted joint, welding to be connected with case lid, and preferred plan is that hypotenuse 10 is made of one together with elastic button 9, case lid 2.

Fig. 5 is the schematic diagram of protective cover when being positioned at make position, and this moment, the hypotenuse 8 of straight hook 7 of protective cover 4 was spacing by 11 of the position-limited edges of going to the bottom of elastic button 9.

Fig. 6 is the schematic diagram of protective cover when being positioned at the enable possition, this moment, elastic button 9 pressurizeds rotated, because the center of rotation 12 of elastic button 9 is lower than its position-limited edge 11 of going to the bottom, when elastic button 9 rotates, its position-limited edge 11 of going to the bottom outwards moves, and when external shift quantity during greater than the width of the crochet 8 of the straight hook 7 of protective cover, the suffered position-limiting action of straight hook disappears, protective cover 4 pops up under the effect of hinged torsion spring 6 automatically, and the operating knob of electrical equipment 3 is exposed.

In most preferred embodiment, protective cover 3 usefulness transparent plastics are made, and are made of one with straight hook 7.Case lid 2, hypotenuse 10, elastic button 9 usefulness plastics are manufactured, and make one with mold injection.

Claims

1. a switch-box is made up of casing and case lid, it is characterized in that:

C. elastic button is connected with at the bottom of the case lid by the hypotenuse of case lid inner chamber between two fingers.

2. switch-box according to claim 1 is characterized in that: two hypotenuse systems of the sensing case lid inner chamber of described elastic button are by 135 ° of angles, and forward and reverse bending forms for twice.

3. switch-box according to claim 1 is characterized in that: described elastic button and bending connect hypotenuse and case lid system makes with the plastic monoblock pressure injection.
