Among the figure: 1 expression shell block; 2 expression binding posts; 3 expression static contacts; 4 expression moving contacts; 5 expression movable contact springs; 6 expression supports; 7 expression Metal Ball; 8 expression sliding sleeves; 9 expression springs; 10 expression elevating levers; 11 expression buttons; 12 expression back-moving springs; 13 expression cage knobs; 14 expression snap closes; 15 expression stage clips; 16 expression cover plates; 17 expression locking press buttons; 18 expression holders; 19 expression self-locking steps; 20 expression lockholes.
Embodiment
The utility model will be further described below with reference to accompanying drawing and by embodiment.
As Fig. 1, shown in Figure 2, Dual-auto-lock electric power tool switch comprises shell block 1, elevating lever 10, button 11, cover plate 16, wherein button 11 is installed on elevating lever 10 upper ends, elevating lever 10 sleeves are in shell block 1, elevating lever 10 lower ends are provided with back-moving spring 12, cover plate 16 is entrenched on the shell block 1 by buckle, on shell block 1 and the cover plate 16 locking press button 17 is housed all, symmetrical two set of connections terminals 2 are housed in the shell block 1, support 6 that is connected with top one set of connections terminal respectively and the static contact 3 that is connected with below one set of connections terminal are equipped with in shell block 1 both sides, be equipped with movable contact spring 5 on the support 6, elevating lever 10 both sides are provided with the sliding sleeve 8 that withstands on the movable contact spring, spring 9 is housed in the sliding sleeve 8, and steel ball 7 is equipped with in the end; 17 of described locking press buttons are made of cage knob 13, snap close 14 and stage clip 15, wherein cage knob 13 is contained on the holder 18, snap close 14 1 ends are contained in the cage knob 13, and stage clip 15 is enclosed within on the snap close 14, snap close 14 other ends have can be chimeric with the self-locking step 19 on the elevating lever 10 lockhole 20.When press push button 11, elevating lever 10 drives down slippage of sliding sleeve 8, because the effect of spring 9, the steel ball 7 of sliding sleeve 8 ends has a pressure point to movable contact spring 5 all the time, when this pressure point during by the supporting point of movable contact spring 5 on support 6, movable contact spring is swung rapidly, and the moving contact on the movable contact spring is contacted with fixed contact on the static contact 3, makes the switch connection power supply.At this moment, if desired the energized state is locked, only need the cage knob on the locking press button 17 13 is pressed, the recess on the elevating lever 10 is stretched in cage knob 13 drive snap closes 14 ends, and self-locking step 19 on elevating lever 10 recesses is embedded in the lockhole 20 of snap closes 14 ends and, make switch keep "on" position elevating lever 10 lockings.When need unlock state, only need press the button 11, deviate from the lockhole 20 of the self-locking step 19 on the elevating lever 10 from the snap close 14, under the effect of stage clip 15, snap close 14 ends break away from the recess on the elevating lever 10, can make elevating lever 10 state that unlocks.When the external force on being applied to button 11 disappears, because the effect of back-moving spring 12, elevating lever 10 drives on the sliding sleeve 8 in reseting procedure and moves, when the pressure point of steel ball 7 on movable contact spring 5 during by the supporting point on the support 6, movable contact spring 5 swing rapidly makes the moving contact on the movable contact spring 5 separate with fixed contact on the static contact 3, thus deenergization.In the open and close process of this switch, steel ball 7 keeps friction with movable contact spring 5 all the time, because steel ball 7 smooth surfaces have characteristics such as coefficient of friction is little, wear-resistant, therefore can effectively alleviate the degree of wear between the switch element; And two set of connections terminals, 2 left-right symmetric are installed on the shell block 1, two groups of contacts are stressed evenly about in the open and close process, improve the stability of switch and the electrical property of switch greatly, and what adopt between dynamic and static contact is the mode of instantaneous break-make, arcing phenomenon between the contact is greatly reduced, thereby prolong the useful life of switch.And adopt buckle chimeric, not only convenient for installation and maintenance between cover plate 16 and the shell block 1, and can effectively reduce the waster rate of product, reduce production costs, but also reduced the staking process in the production process, raise labour productivity.In addition, be arranged on switch cover plate 16 and provide great convenience with 17 operators of locking press button on the shell block 1 for different customs.
