Abstract
The utility model discloses a control switch of electric tools, which comprises a electric control switch, a motherboard(5), a handle(6), and a limited frame(11), wherein, the electric control switch is composed of a switch(4), a button(7), and a reset spring(10), the limited frame(11) is fixed on the motherboard(5), the upper limit arresting pin(8) which be fixed on the handle(6) goes through the limited frame(11), the handle(6) is hinged with the motherboard(5) through a pin roll (9), the handle(6) is provided with a self lock arrangement to prevent wrong operation, the self lock arrangement is composed of a push button(1), a sliding block(3), and a sliding block reset spring(2), the limited frame(11) is provided with a self lock step(12), which coordinate with the self lock arrangement; the handle(6) is provided with a reinforcement(13), the sliding block(3) is arranged under the reinforcement(13). The use of the above structure resolves the problems which exist in the original switch, such as high coordinating precision, great frictional resistance, inconvenient operation; the utility model has the advantages of reasonable structure, convenient operation, high reliability, easy process, and long service life.
Description
One, technical field
The utility model relates to a kind of electric switch, the power control switch that uses on particularly a kind of electric tool.
Two, background technology
Present its base plate of electric tool control switch and lift are connected by being fixed on the bearing pin on the base plate and the straight trough of lift, and resetting of lift realizes that by the back-moving spring that is horizontally set between base plate and the lift its auto-lock function is realized by the groove on the limitting casing; During use, at first need the horizontal applied thrust of armrest, the lift integral body of switch is moved to the left, and make upper arresting pin on the lift break away from groove on the limitting casing, exerting pressure downwards then makes the switch closure conducting; After applied pressure was eliminated, the lift of switch was under the switch action of reset spring, and lift upwards resets, and under the effect of back-moving spring, moved after the lift integral body and resetted, and returned to self-locking state.Above working method exists following drawback: the one, and back-moving spring elastic force is excessive, requires lift thrust left excessive, operation inconvenience; Too small as back-moving spring elastic force configuration, will produce the lift self-locking instability that resets, easily cause self-locking malfunctioning.The 2nd, the quality of fit between lift and each parts requires height, has increased the production difficulty, is unfavorable for controllable quality.The 3rd, the motion that directly rubs of the straight trough of lift and button, lift and lock shaft, resistance is big, useful life is short.
Three, summary of the invention
For overcoming the technical deficiency of above-mentioned existence, problem to be solved in the utility model provide a kind of operate light, reliability is high, the electric tool control switch of handling ease.The technical solution adopted in the utility model is to comprise electric-controlled switch, base plate, lift and limitting casing, electric-controlled switch is made up of switch body, button and back-moving spring, limitting casing is fixed on the base plate, the upper arresting pin that is fixed on the lift passes limitting casing, lift is by bearing pin and base plate hinged, lift is provided with the self-locking device of false action-proof, and the self-locking step is set on the limitting casing, and this step matches with self-locking device; Self-locking device is made up of slip push button, slide block and slide block back-moving spring, the slip push button is fixedlyed connected with slide block, the slide block back-moving spring is arranged in the slide block, and the horizontal bar that reaches on one end and the lift in the slide block contacts, and the slip push button can slide on the respective slot of lift; Lift is provided with reinforcement, and slide block is arranged on the below of reinforcement; Slide block cooperates with step on the limitting casing.After adopting said structure, solved former switch and had quality of fit height, big, the unhandy problem of frictional resistance; Have rational in infrastructure, light, the advantages such as reliability is high, handling ease, long service life of operation.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, embodiment
Shown in Figure 1, specific embodiments for a kind of electric tool control switch of the utility model, it comprises electric-controlled switch, base plate 5, lift 6 and limitting casing 11, electric-controlled switch is by switch body 4, button 7 and back-moving spring 10 are formed, limitting casing 11 is fixed on the base plate 5, the upper arresting pin 8 that is fixed on the lift 6 passes limitting casing 11, lift 6 is hinged by bearing pin 9 and base plate 5, lift 6 is provided with the self-locking device of false action-proof, self-locking device is by slip push button 1, slide block 3 and slide block back-moving spring 2 are formed, slip push button 1 is fixedlyed connected with slide block 3, slide block back-moving spring 2 is arranged in the slide block 3, the horizontal bar 14 that reaches on one end and the lift 6 in the slide block 3 contacts, and slip push button 1 can slide on the respective slot 15 of lift 6; Self-locking step 12 is set on the limitting casing 11, and this step 12 matches with slide block 3; Lift 6 is provided with reinforcement 13, and slide block 3 is arranged on the below of reinforcement 13.
During operation, with the moving push button 1 of the right sliding of hand, slip push button 1 moves to right, and fixedly connected with it slide block 3 moves right together, slide block back-moving spring 2 storage power, and the self-locking step 12 that slide block 3 breaks away from the limitting casings 11, this moment, switch possessed on-condition; The downward then application of force, lift 6 rotates around bearing pin 9, drives button 7 simultaneously and moves downward, and the dynamic and static contact in the switch body is closed contact conducting under the control of button 7.After external force disappears, lift 6 integral body move upward under the elastic force effect of back-moving spring 10, when the upper arresting pin on the lift 68 is run into the upper ledge of limitting casing 11, slide block back-moving spring 2 in the slide block 3 stretches and releases energy, make slide block 3 and slip push button 1 return to reset condition, slide block 3 moved on on the self-locking step 12 of limitting casing 11 and entered self-locking state this moment.
