Summary of the invention
Technical problem to be solved in the utility model is: a kind of unlatching-locking apparatus of tractor hood is provided, and this unlatching-locking apparatus is not only simple in structure, and convenient and reliable operation.
For solving the problems of the technologies described above, the technical solution of the utility model is: the unlatching-locking apparatus of tractor hood, the rear upper end and the hood support of tractor hood are hinged, it comprises the positioning plate that is fixed in tractor frame sidepiece front end, with the jam plate that is rotatably connected with described positioning plate, with the lock of captiveing joint with tractor hood; The top of described jam plate is provided with first open slot along horizontal expansion, and described jam plate has when rotating to be made described lock snap in the locked position of first open slot and make described lock break away from the open position of first open slot; With can make described jam plate go to the joystick of open position, described joystick has with described jam plate pivotally attached pin jointed end and is used for manned free end, position and the described positioning plate of described joystick between pin jointed end and free end is rotatably connected, and is provided with retracing spring between described positioning plate and described jam plate or the joystick.
As a kind of improvement, the top of described positioning plate is provided with upwardly extending second open slot, and the path of motion of described second open slot and described lock is suitable.
Improve as another kind, it also comprises the joystick guide piece that is fixed in described tractor frame, and described joystick guide piece is provided with guide groove, and the free end of described joystick stretches out described guide groove.
After having adopted technique scheme, the beneficial effects of the utility model are: because it comprises positioning plate that is fixed in tractor frame sidepiece front end and the jam plate that is rotatably connected with described positioning plate, with the lock of captiveing joint with tractor hood; The top of described jam plate is provided with first open slot along horizontal expansion, and described jam plate has when rotating to be made described lock snap in the locked position of first open slot and make described lock break away from the open position of first open slot; With can make described jam plate go to the joystick of open position, described joystick has with described jam plate pivotally attached pin jointed end and is used for manned free end, position and the described positioning plate of described joystick between pin jointed end and free end is rotatably connected, be provided with retracing spring between described positioning plate and described jam plate or the joystick, so in use, promote the free end of joystick, joystick is rotated with respect to positioning plate, the pin jointed end of joystick is stirred jam plate and is rotated, when going to the open position, lock breaks away from first open slot, thereby can open tractor hood, under the effect of retracing spring, described jam plate tends to locked position automatically; The tractor hood that closes, lock snaps in first open slot again, and at this moment, retracing spring makes jam plate chucking lock, makes it to be not easy to become flexible, thereby makes the locking of tractor hood very reliable.By above analysis as can be seen, the unlatching of tractor hood and locking operation are very convenient reliable.
Because the top of described positioning plate is provided with upwardly extending second open slot, the path of motion of described second open slot and described lock is suitable, second open slot is in the process of tractor hood of closing, play position-limiting action, so when offset appears in tractor hood, also can make lock snap in first open slot exactly, strengthen its reliability of service.
Because it also comprises the joystick guide piece that is fixed in described tractor frame, described joystick guide piece is provided with guide groove, and the free end of described joystick stretches out described guide groove, so, when promoting joystick, deflection can not occur, strengthen joystick and stirred the reliability that jam plate rotates.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the mounting structure scheme drawing of the utility model embodiment;
Fig. 2 is the enlarged drawing at A place among Fig. 1;
Fig. 3 is the right elevation of Fig. 2.
The specific embodiment
As shown in Figure 1, the rear upper end of tractor hood 1 and hood support 2 are hinged, and the top cover of tractor hood 1 is inboard and be fixed between the bearing 6 of driving engine and be hinged with gas spring 3, when unlatching-locking apparatus is in opening, gas spring 3 stretches, and tractor hood 1 is opened automatically; When closing tractor hood 1, gas spring 3 shrinks, and at this moment, unlatching-locking apparatus is in locking state.
As Fig. 2 and 3 common shown in, bolt clamp device 58 is fixed in tractor frame 4 sidepiece front ends with positioning plate 51, jam plate 52 is rotatably connected to by bolt connecting device 57 with positioning plate 51, lock 53 is captiveed joint with tractor hood 1.The top of jam plate 52 is provided with first open slot along horizontal expansion, and the top of jam plate 52 is provided with the oblique angle, is convenient to lock 53 and snaps in.When jam plate 52 rotates with respect to positioning plate 51, has the open position that can make described lock 53 snap in the locked position of first open slot and can make described lock 53 disengagings first open slot.The top of positioning plate 51 is provided with upwardly extending second open slot, and the path of motion of described second open slot and lock 53 is suitable.The opening part of second open slot of positioning plate 51 is provided with the oblique angle, and its effect also is to be convenient to lock 53 snap in.
Joystick 54 can make jam plate 52 rotate, joystick 54 has with described jam plate 52 pivotally attached pin jointed ends and is used for manned free end, joystick 54 is provided with the bearing pin 54a that is rotatably connected with positioning plate 51, bearing pin 54a is arranged on the position between pin jointed end and the free end, if bearing pin 54a is provided with the position near pin jointed end, and is then comparatively laborsaving.The pin jointed end of joystick 54 stretches out positioning plate 51, and positioning plate 51 is provided with corresponding deep-slotted chip breaker, is provided with retracing spring 56 between the pin jointed end of positioning plate 51 and joystick 54.Certainly, the pin jointed end of joystick 54 also can not stretch out positioning plate 51, as long as it can be hinged with jam plate 52, play the effect of stirring jam plate 52 and gets final product.Retracing spring 56 also can be arranged between positioning plate 51 and the jam plate 52, and its effect is, when opening, makes jam plate 52 trend locked positions, guarantees that jam plate 52 automatically resets; When locking state, make jam plate 52 chucking locks 53 be not easy to produce loosening.
