Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described, and the illustrative examples invented at this and explanation are for explaining the present invention, but not as a limitation of the invention.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, a kind of electric brake knife-like switch, including housing, push-pull bar 10, flexible electricity cylinder 7, crossbeam 12, emergent pull bar 4, housing includes procapsid 1 and back casing 2, lower housing portion middle position is provided with flexible electricity cylinder 7, being provided with plug 18 bottom flexible electricity cylinder 7, described plug 18 top is provided with jump ring 17, and jump ring 17 is fastened with the piston rod of flexible electricity cylinder 7.Push-pull bar 10 slides up and down and is arranged in flexible electricity cylinder 7, push-pull bar 10 bottom and jump ring 17 card dress.Push-pull bar 10 top is provided with push-and-pull ring 3, is provided with baffle ring 13 below described push-and-pull ring 3, is installed with crossbeam 12 in the middle part of push-pull bar 10, and crossbeam 12 is slidably mounted in two vertical chutes 9, and two described vertical chutes 9 are separately mounted to enclosure interior both sides.Being set with uprighting spring 14 and lower uprighting spring 15 on push-pull bar 10, described upper uprighting spring 14 upper end contacts with baffle ring 13 lower surface, and upper uprighting spring 14 lower end contacts with crossbeam 12 upper surface.Lower uprighting spring 15 upper end contacts with crossbeam 12 lower surface, and lower uprighting spring 15 lower end contacts with the step surface of push-pull bar 10 bottom.Before and after crossbeam 12, the most uniform internal both sides of four slotting tools 16, procapsid 1 and back casing 2 that are provided with, both sides are separately installed with four sockets 5, and corresponding with the slotting tool 16 on crossbeam 12 respectively.Both sides, crossbeam 12 top are separately installed with a snap-action 11, snap-action 11 is slidably fitted with slide block 20, described slide block 20 one end is rotatablely equipped with pulley 19, and slide block 20 other end is provided with crossed strip 23, and two pulleys 19 contact with each other with enclosure interior both sides respectively.Middle position, enclosure interior both sides is respectively arranged with upper hopper chute 21 and gliding groove 22.It is internal that emergent pull bar 4 is slidably mounted on push-pull bar 3, and emergent pull bar 4 lower end is fitted in jump ring 17 top.
Being respectively arranged with electricity cylinder lug 6 outside procapsid 1 and back casing 2, described electric cylinder lug 6 is connected with the electric wire 8 of enclosure interior respectively, and described electric wire 8 is connected with flexible electricity cylinder 7.Upper hopper chute 21 and gliding groove 22 are semicircle, and match with the external diameter of pulley 19.When emergent pull bar 4 is pressed downward against jump ring 17, described push-pull bar 10 is disconnected with the piston rod of flexible electricity cylinder 7.
The operation principle of the present invention is: the present invention is in use, mainly by jump ring 17, the piston cylinder of push-pull bar 10 with flexible electricity cylinder 7 is connected, when flexible electricity cylinder 7 does not works, two pulleys 19 lay respectively in two upper hopper chutes 21, now the slotting tool 16 on crossbeam 12 contacts with the socket 5 on housing respectively, i.e. the present invention is now in closure state；When the piston rod downward actuation of flexible electricity cylinder 7, push-pull bar 10 is driven to move downward by jump ring 17, push-pull bar 10 drives upper uprighting spring 14 and lower uprighting spring 15 to compress, when the pressure of upper uprighting spring 14 and lower uprighting spring 15 reaches to a certain degree, time i.e. more than the pressure of the crossed strip 23 in two snap-actions 11, two pulleys 19 quickly skid off from two upper hopper chutes 21, and slide down in gliding groove 22, now the slotting tool 16 on crossbeam 12 departs from the socket 5 on housing, i.e. the present invention is now in off-state；Occur when there being fortuitous event, when flexible electricity cylinder 7 cannot work, emergent pull bar 4 can be pressed downward against, thus the piston rod of jump ring 17 with push-pull bar 10 and flexible electricity cylinder 7 is departed from from card dress state, will the piston rod of push-pull bar 10 and flexible electricity cylinder 7 depart from, pull push-pull bar 10 now by push-and-pull ring about 3, crossbeam 12 can be driven to realize contacting and disengaging of slotting tool 16 and socket 5, i.e. realize quickly disconnecting and Guan Bi of the present invention.
