Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
The fork truck emergency stop switch of false-touch prevention as shown in Figures 1 to 6, including bottom and button 1, button 1 are equipped with locking device, lock
Determine device include lock-button 2, interior 3, limited wall 6, linkage mechanism and locking pin 5, button 1 includes side wall, in button 1 is fixed on
Platform 3 and with interior 3 synchronizing movings, limited wall 6 is sheathed on outside side wall, and side wall and limited wall 6 are equipped with lock hole 60, lock-button 2
It issues and is equipped with extending column 21, extending column 21 follows 2 synchronizing moving of lock-button, and interior 3 equipped with movable for 21 axis of extending column
Telescopic chute 31, extending column 21 make locking pin 5 be actively located in two lock holes 60 with lock-button 2 up and down through linkage mechanism
In.
As shown in Figure 4 and Figure 5, linkage mechanism includes lever 4, driving protrusion 210 and driven protrusion 50, and 4 middle part of lever is turned over
Turn to be connected in interior 3, the both ends of lever 4 are equipped with driving shifting chute 41 and driven shifting chute 42, and driving protrusion 210, which is fixed on, prolongs
Column 21 is stretched, 5 inner end of locking pin is fixed in driven protrusion 50, and protrusion 210 and driven protrusion 50 is driven to be located in respective shifting chute.
As shown in figure 4, when lock-button 2 is in pop-up state, locking pin 5 is in the state of pop-up, and locking pin 5 is inserted into limit
Position wall 6 and 1 side wall of button lock hole 60 in so that button 1 can not relative limit wall 6 relatively move, button 1 pushing after
It can not move, therefore press 1 edge position of button at this time, emergency stop switch will not stop the running of machine.
As shown in figure 5, and when user press middle part lock-button 2 when, lock-button 2 drives successively extending column 21 and drive
Protrusion 210 moves down, and lever 4 drives end to be pressed down, and the driven end of lever 4 is then upturned, while driving locking pin 5
Driven protrusion 50 moves inward along driven shifting chute 42, at this time the abjection out of lock hole 60 of locking pin 5,1 side wall of button and
Limitation between limited wall 6 is released from so that 1 side wall relative limit wall 6 of button can move, and pressing button 1 at this time can make
It obtains entire button 1 to move down, until shown in Fig. 6.
