Abstract
The utility model relates to a switch of an electric tool. The utility model is composed of a casing, a handle rack, a swing rack, a spring fossa seat, a cone spring, a pin shaft, a handle, a screw, a pressing sheet, a positioning cover, a rubber pad, a spring, a movable contact rack, a wiring terminal, a pin line screw, a supporting seat, a static contact rack, etc. When the utility model is used, the handle which is operated can cause contacts of the movable contact rack and the static contact rack to be quickly contacted or disconnected with each other; thus, the electric tool can be switched on, or the breaking current of the electric tool can be realized. The utility model has the advantages of flexible operation, small contact resistance, long service life, etc. The utility model is suitable for various electric tools.
Description
The utility model relates to a kind of electric tool switch, belongs to a kind of contact contact instantaneous operation switch.
In the existing electric tool,,, there are shortcomings such as contact resistance is big, easily heating, rated current is low, the life-span is short because contact is the resilient sheet-like structure though some switch has the instantaneous operation structure.Though the switch that has is the contact contact, owing to adopt the wriggling structure, actuating speed is relevant with operating parts, does not have instantaneous operation, and underaction during operation influences its service behaviour.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art the electric tool switch that a kind of actuating is flexible, the life-span is long is provided.
Electric tool switch provided by the utility model, has housing (1), handle frame (2), swing span (3), spring nest seat (4), awl spring (5), bearing pin (6), handle (7) and be fixed on clamping piece (9) on the housing (1) by screw (8), location lid (10), valve rubber (11) and be located at binding post (16) and locking wire screw (17) on the housing (1), wherein be provided with the moving contact frame (13 that compresses by spring (12) in the groove of swing span (3) lower end, 14), also be provided with the bearing (18 of swinging in the cross rest frame (3) in the housing (1), 19) be fixed on screw (15) and decide contact frame (20 on the binding post (16), 21).
Following accompanying drawing has provided an embodiment of the present utility model:
Fig. 1 is the utility model structural representation.
Fig. 2 is STRUCTURE DECOMPOSITION figure of the present utility model.
Among the figure: (1) expression housing; (2) expression handle frame; (3) expression swing span; (4) expression spring nest seat; (5) expression awl spring; (6) expression bearing pin; (7) expression handle; (8) expression screw; (9) expression clamping piece; (10) expression location lid; (11) expression valve rubber; (12) expression spring; (13), (14) expression moving contact frame; (15) expression screw; (16) expression binding post; (17) expression locking wire screw; (18), (19) bearing; (20), (21) decide the contact frame.
The utility model will be further described below in conjunction with accompanying drawing (embodiment).
According to Fig. 1, Fig. 2, the utlity model has a housing (1), handle (7) is contained on the handle frame (2) with bearing pin (6), handle frame (2) is by clamping piece (9) and location lid (10), valve rubber (11) is fixed on the housing (1), be provided with spring nest seat (4) in the housing (1), awl spring (5), swing span (3), bearing (18,19), moving contact frame (13,14) and decide contact frame (20,21), swing span (3) is placed on bearing (18,19) on, spring nest seat (4) and awl spring (5) are placed in the groove on the swing span (3), moving contact frame (13,14) be pressed in the groove of swing span (3) lower end with spring (12), decide contact frame (20), (21) be fixed on the binding post (16) on the housing with screw (15).During operation, the direction of pulling by joystick (7), make swing span (3) swing, because the elastic force effect of spring (12), contact on the moving contact frame (13,14) is promptly contacted with contact on deciding contact frame (20), (21) or disconnect, finish to be switched on or switched off action in moment, thereby realize that electric tool is connected or the purpose of breaking current.Because the utility model has adopted the instantaneous operation structure of contact contact, it is little therefore to have a contact resistance, is difficult for heating, and the life-span is long, advantages such as flexible operation.
Claims (1)
1, a kind of electric tool switch, comprise housing (1), handle frame (2), swing span (3), spring nest seat (4), awl spring (5), bearing pin (6), handle (7) and be fixed on clamping piece (9) on the housing (1) by screw (8), location lid (10), valve rubber (11), be located at binding post (16) and locking wire screw (17) on the housing (1), be fixed on by screw (15) and decide contact frame (20 on the binding post (16), 21) and be fixed on the bearing (18 of the swinging in the cross rest frame (3) in the housing, 19), it is characterized in that being provided with the moving contact frame (13 that compresses with spring (12) in the groove of swing span (3) lower end, 14).
