The conductive bearing base (9) and two electrode slices (7) are fixed in the bottom case by a connector column (8). The case cover (4) is covered on the bottom case (5). A rocker arm (12) with the two arms there of arranged a magnetic body (3) is installed at the back side of the case cover (4) by a pin. A spring (11) is arranged inside the rocker arm (12). The button (2) with the magnetic body (3) at both ends is installed at the surface of the case cover (4) by a pin. A power on and off mechanism is arranged at the bearing base (9) and the rocker arm (12) there between. The utility model provides the advantages of simple structure, convenient using, water proof and explosion prevention. The utility model can be widely applied in flammable and explosive situations such as factory, mine, gas station etc, or wet situations such as kitchen, bathroom etc.

Description

The waterproof anti-explosion switch

Technical field: the utility model relates to a kind of mains switch, relates in particular to a kind of mains switch with anti-riot water-proof function.

Background technology: at present, traditional mains switch mostly is Open architecture greatly, owing to there are not its most of electric elements of obturator to be directly exposed in the air, therefore cause easily in the environment of humidity, many water and gets an electric shock or short circuit accident, and is very dangerous; Simultaneously, traditional mains switch is easy to generate arc light or spark in the course of the work, and the various injury accidents of Chan Shenging happen occasionally therefrom, especially can not be applicable to inflammable and explosive occasion; In addition, traditional mains switch usually causes the loose contact of each electrical pickoff because its most of live components is subjected to erosion, the oxidation of air easily, has reduced reliability of products and useful life.

Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of waterproof anti-explosion switch that can use in the many water of humidity, multiple environment such as inflammable and explosive.

To achieve these goals, the utility model by the following technical solutions: it comprises end box, lid, button, electrode slice and bearing; The bearing and the two cube electrode sheets of conduction are fixed in the end box by binding post, lid covers hermetically on end box, the rocking arm that two arms are provided with magnet is installed in the back side of lid by bearing pin, and the inside of rocking arm is provided with spring, and the button that two is provided with magnet is installed in the surface of lid by bearing pin; Between bearing and rocking arm, be provided with power on/off mechanism.

Described power on/off mechanism is by being installed in conduction lever on the bearing, being inserted in the rocking arm and the driving lever of length of spring compressed being constituted; Bearing is that an end is provided with screw thread, the other end is the rod shaped structure of bulb; Described power on/off mechanism is that an end is installed on the bearing, the other end is inserted in the rocking arm and with the conduction driving lever of length of spring compressed; Bearing is that an end is provided with the block structure that screw rod, the other end are provided with the ball-type pit; Be fixed with panel on the lid.

Compared with the prior art, the utility model is owing to all be enclosed in end box in by lid all live components, thereby overcome the defective that the conventional power source switch can not use in humidity many water, multiple environment such as inflammable and explosive, avoided effectively causing getting an electric shock, the generation of accident such as short circuit because of making moist; In addition, because all live components are all isolated with air, can not cause major accidents such as blast or fire even if therefore in use produce spark or arc light yet; Simultaneously, each electrical pickoff also can not be subjected to the erosion and the oxidation of air, therefore improved greatly each electrical pickoff contact stabilization and reliability, prolonged useful life of product.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of another embodiment of the utility model.

Among the figure: panel 1 button 2 magnets 3 lids 4 end box 5 driving levers 6 electrode slices 7 binding posts 8 bearings 9 conduction levers 10 springs 11 rocking arms 12 conduction driving levers 13

Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

Embodiment 1, and as shown in Figure 1: box 5 internal fixation in the end have three binding posts 8, and are airtight between each binding post 8 and the end box 5; It is that two cube electrode sheets 7 are fixed on the binding post 8 of bearing 9 both sides symmetrically by screw on the binding post 8 in the middle of bearing 9 that bulb is rod shaped structure is fixed on by screw thread that one end is provided with screw thread, the other end.Lid 4 is fixed on the end box 5 and the box mouth is airtight, and the rocking arm 12 of T font is installed in the back side of lid 4 by bearing pin, and its two arm is provided with magnet 3, its inside is provided with spring 11; The button 2 that two is provided with magnet 3 is installed in and corresponding lid 4 surfaces, rocking arm 12 positions by bearing pin.Be provided with power on/off mechanism between bearing 9 and the button 2, this mechanism is inserted in the rocking arm 12 and with spring 11 compressions and the driving lever 6 that the other end contacts with conduction lever 10 constitutes by being provided with the ball-type positioning pit and being installed in conduction lever 10, an end on the bearing 9 by this hole.

Embodiment 2, the utility model can also adopt structure shown in Figure 2: promptly changing bearing 9 into an end under the constant situation of basic structure is that screw rod, the other end are provided with the block structure of ball-type pit, and to adopt an end be that bulb shape, both sides are provided with the conduction driving lever 13 that the contact is decussate texture and substitute driving lever 12 and conduction lever 6 as power on/off mechanism; The end that conduction driving lever 13 is provided with bulb is installed in the pit of bearing 9, the other end inserts in the rocking arm 12 and with spring 11 compressions.

For attractive in appearance, in above-mentioned two embodiment, also can on lid 4, fix a panel 1.

The utility model both can be used as single control switch and had used, and can be used as double control switch again and used.
