Description

Rocker switch

Technical field:

The utility model relates to a kind of switch that is used on the small household appliance, especially rocker switch.

Background technology:

Rocker switch is widely used on the small household appliance, its version has multiple, mainly form by a kind of structure of rocker switch at present by button, support, pedestal, contact bridge, middle-end, bent-up end, middle-end and bent-up end are fixed on the pedestal lower end, contact bridge places and forms seesaw on the middle-end, press contact bridge and can make it with bent-up end contact or separate, realize the closed and disconnected of circuit.Be placed in the button, button and pedestal are hinged, and the lower end of support is equipped with spring and gland, gland withstands on the contact bridge, presses the button support and rotates thereupon, can make gland be in the both sides that contact bridge is lifted up activity supporting point, under the effect of spring, achieve a butt joint and touch the location of bridge.Because support and button are movable parts, all have the gap between support and the pedestal and between button and the pedestal, can not waterproof and dustproof, in water enters pedestal, can cause and leak electricity or short circuit, use dangerous; In dust enters pedestal, easily make the support activity dumb, dust enters between contact bridge and the terminal, also can hinder contacting of contact bridge and terminal, causes loose contact.

The utility model content:

Can not waterproof and dustproof deficiency in order to overcome existing rocker switch, the utility model provides a kind of rocker switch, this rocker switch is waterproof and dustproof, have simple in structure, cost low and the water proof and dust proof good effectiveness.

The technical solution of the utility model is: this rocker switch comprises pedestal, middle-end, contact bridge and bent-up end, fixedly middle-end and bent-up end on the pedestal, contact bridge place on the middle-end and with middle-end for lifting up activity supporting point, pedestal top is connected with loam cake, cover and centring ring in being equipped with in the loam cake, in be placed in the centring ring and be hinged with centring ring, interior set upper side is spherical and has and the corresponding centre bore of last tops circular hole, be provided with sealing ring between interior cover and the loam cake, interior cover lower end is equipped with spring and gland, and gland withstands on the contact bridge.

The outside of described centring ring has the ear post of 2 symmetries, on the end face of ear post cylindrical bump is arranged, and centring ring is connected in the loam cake by described projection.

Be plugged with button in the centre bore of cover in described.

Described loam cake and pedestal clamping mutually.

The utlity model has following beneficial effect: owing to take such scheme, be provided with sealing ring between interior cover and the loam cake, interior cover is positioned to enclose with sealing ring and compresses, sealing ring cooperates with the spherical of interior set upper side, the better seal effect is arranged, can effectively stop water, dust etc. to enter in the pedestal, simple in structure, cost is low, and water proof and dust proof is effective.

Description of drawings:

Accompanying drawing 1 is a structure cutaway view of the present utility model;

Accompanying drawing 2 is exploded views of the present utility model.

1-loam cake among the figure, cover in the 2-pedestal, 3-, 4-button, 5-centring ring, 6-spring, 7-gland, 8-middle-end, 9-contact bridge, 10-bent-up end, 11-sealing ring, 12-ear post, 13-projection.

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

By Fig. 1 in conjunction with shown in Figure 2, this rocker switch comprises pedestal 2, middle-end 8, contact bridge 9 and bent-up end 10, fixedly middle-end 8 and bent-up end 10 on the pedestal 2, contact bridge 9 place on the middle-end 8 and with middle-end 8 for lifting up activity supporting point, pedestal 2 tops are connected with loam cake 1, cover 3 and centring ring 5 in being equipped with in the loam cake 1, interior cover 3 places in the centring ring 5 and with centring ring 5 and is hinged, interior cover 3 upper ends are spherical and have and the corresponding centre bore of loam cake 1 top circular hole, be provided with sealing ring 11 between interior cover 3 and the loam cake 1, interior cover 3 lower ends are equipped with spring 6 and gland 7, and gland 7 withstands on the contact bridge 9.In be provided with sealing ring 11 between cover 3 and the loam cake 1, interior cover 3 and sealing ring 11 are positioned and enclose 5 and compress, sealing ring 11 cooperates with the spherical of interior cover 3 upper ends, the better seal effect is arranged, can effectively stop water, dust etc. to enter in the pedestal 2, simple in structure, cost is low, and water proof and dust proof is effective.

By shown in Figure 2, the outside of described centring ring 5 has the ear post 12 of 2 symmetries, and cylindrical bump 13 is arranged on the end face of ear post 12, and centring ring 5 is connected in the loam cake 1 by described protruding 13.Centring ring 5 not only is convenient to install but also can compress interior cover 3 and sealing ring 11.

By shown in Figure 1, be plugged with button 4 in the centre bore of described interior cover 3.Button 4 is in the outside of loam cake 1, and the center has a pin that matches with the centre bore of interior cover 3, and is easy for installation.
