Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of automobile cab Locking Device, can have that structure is simple, flexible adjustment, easy to operate feature, and connection reliability is higher, improves automobile safety performance under steam.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of automobile cab Locking Device, comprise: pressure plate and the lock dog be arranged on described pressure plate, stops, hydraulic actuating cylinder and signal switch, the top of described hydraulic actuating cylinder is positioned at immediately below described stops one end, and promote described stops by described hydraulic actuating cylinder top and swing, described lock dog is fixed with the first pull back spring, described stops is fixed with the second pull back spring, described stops swings and can withstand on below described lock dog, the connecting rod be connected on described signal switch is provided with between described signal switch and described first pull back spring.
In a preferred embodiment of the present invention, be articulated and connected by rivet between described lock dog and described pressure plate, and described first pull back spring is fixed on the rivet of this hinged place, lock dog return can be made rapider.
In a preferred embodiment of the present invention, be articulated and connected by rivet between described stops and described pressure plate, and described second pull back spring is fixed on the rivet of this hinged place, stops return can be made rapider.
In a preferred embodiment of the present invention, be bolted to connection between described signal switch and described pressure plate.
In a preferred embodiment of the present invention, described pressure plate is also provided with multiple locating dowel pin.
In a preferred embodiment of the present invention, the surface of described lock dog and described stops all has projection.
The invention has the beneficial effects as follows: the present invention is by rationally arranging the relative position of lock dog and stops, when stops is rotated to below lock dog, stops can be pinned, achieve the object of device to operator's compartment locking, adopt lock dog to realize switching on and off signal switch to the extruding of connecting rod with withdrawing simultaneously, be quick on the draw, without unnecessary consumption.
Accompanying drawing explanation
Fig. 1 is the present invention's structural representation in a preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, pressure plate, and 2, lock dog, 3, stops, the 4, second pull back spring, 5, hydraulic actuating cylinder, the 6, first pull back spring, 7, signal switch, 8, connecting rod, 9, locating dowel pin.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention has:
A kind of automobile cab Locking Device, comprise: pressure plate 1, lock dog 2, stops 3, hydraulic actuating cylinder 5 and signal switch 7, locating dowel pin 9 is provided with above the left side of described pressure plate 1, , for limiting the rotational steps of lock dog 2, above the right side of described pressure plate 1, below is equipped with locating dowel pin 9, for limiting the rotational steps of stops 3, the V-shaped shape of described lock dog 2, and be hingedly mounted on by rivet on the left of pressure plate 1 in vee-block center, described lock dog 2 can rotate around this rivet, described stops 3 is in shape, and be hingedly mounted on the right side of pressure plate the center of Z-shaped piece by rivet, described stops 3 can rotate around this rivet, thus by the locking of the implement device that cooperatively interacts between stops 3 and lock dog 2, described hydraulic actuating cylinder 5 is fixed on pressure plate 1 by the mode of bolt, and the top of described hydraulic actuating cylinder 5 is right against the below of described lock dog 2 left-hand end,
The right-hand end of described lock dog 2 has protruding 10, and in the hinged place of lock dog 2, first pull back spring 6 is installed, one end of first pull back spring 6 pushes down described protruding 10, the other end pushes down the locating dowel pin 9 being fixed on top on the right side of pressure plate 1, when lock dog 2 rotates, protruding 10 limiting steering pins 9, make the first pull back spring 6 produce returning elastic; The both sides of the hinged place of described stops 3 have protruding 10, and in the hinged place of stops 3, second pull back spring 4 is installed, second pull back spring 4 one end becomes hook-shaped, for catching on the locating dowel pin 9 being positioned at pressure plate 1 lower right-hand side, the other end pushes down the projection 10 on the left of described only 3 pieces of intersections, when stops 3 rotates, protruding 10 turn to the locating dowel pin 9 being positioned at pressure plate 1 lower right-hand side, make the second pull back spring 4 produce returning elastic;
Described signal switch 7 is bolted on the edge on the left of pressure plate 1, and between signal switch 7 and the first pull back spring 6, there is the connecting rod 8 be connected on described signal switch 7, described connecting rod 8 is subject to the extruding of described first pull back spring 6 and withdraws to realize switching on and off of described signal switch 7.
Further illustrate, present invention is disclosed a kind of automobile cab Locking Device, its specific works principle is: when automobile cab falls after rise, stops 3 pushed down by briquetting on operator's compartment, make stops 3 do left-hand revolution, rotate to when contacting with lock dog 2, lock dog 2 does clickwise, until when stops 3 rotates to lock dog 2, lock dog 2 and stops 3 keep lockup state, when needs are unblanked, open the hydraulic oil of the hydraulic actuating cylinder 5 be fixed on pressure plate 1, the front end upwards jack-up of hydraulic actuating cylinder 5, when top is to forcing lock dog 2 to continue clickwise during lock dog 2, stops 3 continues to do left-hand revolution and withdraws gradually with lock dog 2, along with lock dog 2 rotate the connecting rod 8 to being positioned in the middle of lock dog 2 and signal switch 7 time, stops 3 and lock dog 2 are thoroughly withdrawn, under the effect of the second pull back spring 4, the rapid cw return of stops 3 is until locating dowel pin 9 place, meanwhile connecting rod 8 presses to signal switch 7 by the extruding of lock dog 2, thus connection signal opens 7 passes, hydraulic actuating cylinder 5 quits work, under the effect of the first pull back spring 6, lock dog 2 is conter clockwise return rapidly, thus realize unblanking.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification sheets of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
