Description
Technical field
The present invention relates to the tractor hood technical field, particularly relate to a kind of device that is used to open and lock tractor hood.
Background technology
In order to safeguard the motor that is installed on tractor hood inside, often need open tractor hood.Most tractor hood, its rear upper end and hood support are hinged, then at its front lower ends and tractor frame with being threaded, when opening hood, at first nut is connected and takes apart, when closing hood, again with nut screwing clamping, it is very inconvenient to operate.
Summary of the invention
Technical problem to be solved by this invention 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, technical scheme of the present invention is: the unlatching-locking apparatus of tractor hood, the rear upper end and the hood support of tractor hood are hinged, it comprises the limiting plate that is fixed in tractor frame sidepiece front end, with the jam plate that is rotatably connected with described limiting plate, with the lock of fixedlying connected 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 enable possition of first open slot; With can make described jam plate go to the control stick of enable possition, described control stick has with the hinged hinged end of described jam plate and is used for manned free end, position and the described limiting plate of described control stick between hinged end and free end is rotatably connected, and is provided with back-moving spring between described limiting plate and described jam plate or the control stick.
As a kind of improvement, the top of described limiting plate is provided with upwardly extending second open slot, and the movement locus of described second open slot and described lock is suitable.
Improve as another kind, it also comprises the control stick guiding device that is fixed in described tractor frame, and described control stick guiding device is provided with gathering sill, and the free end of described control stick stretches out described gathering sill.
After having adopted technique scheme, the invention has the beneficial effects as follows: because it comprises limiting plate that is fixed in tractor frame sidepiece front end and the jam plate that is rotatably connected with described limiting plate, with the lock of fixedlying connected 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 enable possition of first open slot; With can make described jam plate go to the control stick of enable possition, described control stick has with the hinged hinged end of described jam plate and is used for manned free end, position and the described limiting plate of described control stick between hinged end and free end is rotatably connected, be provided with back-moving spring between described limiting plate and described jam plate or the control stick, so in use, promote the free end of control stick, control stick is rotated with respect to limiting plate, the hinged end of control stick is stirred jam plate and is rotated, when going to the enable possition, lock breaks away from first open slot, thereby can open tractor hood, under the effect of back-moving 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, back-moving 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 limiting plate is provided with upwardly extending second open slot, the movement locus 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 the position skew appears in tractor hood, also can make lock snap in first open slot exactly, strengthen its dependability.
Because it also comprises the control stick guiding device that is fixed in described tractor frame, described control stick guiding device is provided with gathering sill, and the free end of described control stick stretches out described gathering sill, so, when promoting control stick, deflection can not occur, strengthen control stick and stirred the reliability that jam plate rotates.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the mounting structure schematic diagram of the embodiment of the invention;
Fig. 2 is the enlarged drawing at A place among Fig. 1;
Fig. 3 is the right view 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 motor and be hinged with air spring 3, when unlatching-locking apparatus is in opening, air spring 3 stretches, and tractor hood 1 is opened automatically; When closing tractor hood 1, air 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 limiting plate 51, jam plate 52 is rotatably connected to by bolt connecting device 57 with limiting plate 51, lock 53 is fixedlyed connected 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 limiting plate 51, has the enable possition 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 limiting plate 51 is provided with upwardly extending second open slot, and the movement locus of described second open slot and lock 53 is suitable.The opening part of second open slot of limiting plate 51 is provided with the oblique angle, and its effect also is to be convenient to lock 53 snap in.
Control stick guiding device 55 is fixed in tractor frame 4, and described control stick guiding device 55 is provided with gathering sill, and the free end of control stick 54 stretches out described gathering sill and is provided with handle.
During use, promote the free end of control stick 54, control stick 54 rotates around bearing pin 54a, its hinged end is stirred jam plate 52 and is rotated, and when jam plate 52 went to the enable possition, lock 53 broke away from first open slot, tractor hood 1 is opened automatically under the effect of air spring 3, at this moment, under the effect of back-moving spring 56, jam plate 52 is the trend locked position automatically; The tractor hood 1 that closes is because the effect of second open slot of limiting plate 51 also can make lock 53 snap in first open slot of jam plate 52 exactly even occur at tractor hood 1 under the situation of position skew.Under the effect of back-moving spring 56, jam plate 52 chucking locks 53 make it to be not easy to become flexible, thereby make the locking of tractor hood very reliable.
