Description
Technical field
The present invention relates to the jockey of agricultural machinery power traction, be specifically related to a kind of quick lower link and hang butt hook.
Background technology
The power traction of agricultural machinery is directly connected to the quality of farming efficiency, it is insecure and cause fault such as unhook that clamping easily takes place in operation process the suspension butt hook of existing agro-farming machinery power traction, and its complex structure, dismounting, the installation exercise operation is loaded down with trivial details, influenced the operating efficiency of agro-farming machinery greatly.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple in structure, dismounting, easy for installation, operation efficiently fast lower link hang butt hook.
Hang butt hook for solving the problems of the technologies described above a kind of quick lower link of the present invention, comprise that the top is provided with the butt hook main body of pressing plate, described butt hook main body below is provided with synanche, and described butt hook main body also is built-in with lock shaft; Described pressing plate one end is provided with " V " shape stopper slot; Described butt hook main body top is provided with the straight pin corresponding with " V " shape stopper slot; Described straight pin is connected with " V " shape stopper slot; The stage casing of described pressing plate is provided with cylindrical towing pin, and described cylindrical towing pin is connected with lock shaft one end, and the other end side of described lock shaft is provided with concave surface; The lock shaft stage casing also is built-in with spring; The other end of described pressing plate fixedly has built-in stage clip and be provided with handle above pressing plate by rivet.
The present invention realizes the axle bush clamping by tilting lock shaft upper and lower displacement in the butt hook main body and loosens.The lower end of lock shaft is provided with the concave surface that matches with axle bush outer ring arc near synanche one side, lock shaft by pressing plate compress press down after, the built-in spring of lock shaft can compress the lock shaft concave surface and the axle bush outer ring is spacing; The upper end of lock shaft is connected with the pressing plate stage casing by cylindrical towing pin.During operation by tension and compression plate on the handle, when moving on pressing plate one end, its stage casing by cylindrical towing pin drive that lock shaft moves up, the straight pin that arranges on the butt hook main body slides into the other end at " V " of pressing plate shape stopper slot one end; Move the built-in stage clip of fixing by rivet in the rear fender on the lock shaft and become the tensioning shape, the spring that arranges in the lock shaft becomes compressive state.
After moving on the lock shaft, the synanche opening of butt hook main body below increases, and axle bush can be filled in easily from the synanche opening part.Press down pressing plate by handle again, on the pressing plate fixing built-in stage clip suppress downwards reset, spring reset that lock shaft is built-in; Lock shaft presses down under built-in stage clip and spring acting in conjunction and is spacing, and straight pin resets in " V " shape stopper slot simultaneously.Lock shaft reaches that concave surface and the axle bush outer ring of its lower end compresses behind the lock position, effectively limits the axle bush slippage.Behind lock shaft and the axle bush locking, the common prevention lock shaft under the compressing of the spring that lock shaft is put within it and the built-in stage clip of pressing plate is to top offset, axle bush efficiently in synanche spacing preventing come off.
The present invention is simple in structure, easy to operate, can realize dismounting and the maintenance of its synanche internal axle bushing fast, significantly improves work efficiency.
Description of drawings
Fig. 1 is lockup state schematic diagram of the present invention;
Fig. 2 is open mode schematic diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2; A kind of quick lower link hangs butt hook, comprises that the top is provided with the butt hook main body 1 of pressing plate 9, and described butt hook main body 1 below is provided with synanche 11, and described butt hook main body 1 also is built-in with lock shaft 6; Described pressing plate 9 one ends are provided with " V " shape stopper slot 2; Described butt hook main body 1 top is provided with the straight pin 3 corresponding with " V " shape stopper slot 2; Described straight pin 3 is connected with " V " shape stopper slot 2; The stage casing of described pressing plate 9 is provided with cylindrical towing pin 5, and described cylindrical towing pin 5 is connected with lock shaft 6 one ends, and the other end side of described lock shaft 6 is provided with concave surface 12; Lock shaft 6 stage casings also are built-in with spring 7; The other end of described pressing plate 9 fixedly has built-in stage clip 4 and be provided with handle 13 above pressing plate 9 by rivet 8.
Embodiment one
As shown in Figure 1, synanche 11 openings of the present invention increase, and insert axle bush 10 backs and realize lockup state by lock shaft tilting in the butt hook main body 16 to bottom offset.Lock shaft 6 moves down the openings get smaller of back synanche 11, and simultaneously lock shaft 6 lower end concave surfaces 12 coincide with the axle bush 10 outer ring cambered surfaces of inserting, and axle bush 10 is spacing to connect operation.Concrete operations are as follows:
Synanche 11 openings of the present invention are inserted axle bush 10 after increasing fast below synanche 11.The staff presses down pressing plate 9 by handle 13 again, its middle part drive was passed through the lock shaft 6 of connecting pin 5 connections to bottom offset when pressing plate 9 pressed down, lock shaft 6 is behind bottom offset and location, it is further spacing that lock shaft 6 built-in springs 7 compress lock shaft 6, reset downwards to compress by the fixing built-in stage clips 4 of rivet 8 simultaneously and guarantee that lock shaft 6 lockings, pressing plate 9 press down the state of the straight pin 3 that arranges on the back clevis main body 1 when being reset to locking of the present invention in " V " shape stopper slot 2.The openings get smaller of lock shaft 6 synanche 11 behind the bottom offset, the concave surface 12 that lock shaft 6 lower ends arrange is superimposed and spacing with the axle bush 10 outer ring cambered surfaces of inserting, realize lock shaft 6 lockings by compressing of spring 7 and built-in stage clip 4, axle bush 10 can not come off behind the locking in synanche 11 but can rotate to adapt to the operation needs in synanche 11.The staff pulls by the connection of axle bush 10 can realize high-efficient homework.
Embodiment two
As shown in Figure 2, the present invention realizes the open mode of synanche 11 to top offset by tilting lock shaft 6 in the butt hook main body 1.The opening that moves back synanche 11 on the lock shaft 6 increases, and axle bush 10 can be inserted wherein.Concrete operations are as follows:
The staff upwards lifts tension and compression plate 9 by handle 13, and to top offset, lock shaft 6 is subjected to displacement its built-in spring 7 of back and is pressed into compressive state by the lock shaft 6 of connecting pin 5 connections in its middle part drive when lifting on the pressing plate 9; Pressing plate 9 draws simultaneously upwards lifting, the state that the straight pin 3 that upwards draws and lifts setting on pressurized, the butt hook main body 1 by rivet 8 fixing built-in stage clips 4 it on slides into the present invention in " V " shape stopper slot 2 when opening; The opening of lock shaft 6 synanche 11 behind the top offset increases, and can carry out next step operation.
The present invention's like product relatively in the past has advantages such as simple in structure, easy to operate, and its dismounting, installation exercise are convenient and swift, axle bush 10 synanche 11 in spacing firmly.
