Description

Anti-theft lock for agriculture machine vehicle

The utility model relates to the automobile-used anti-money lock of a kind of agricultural machinery, is specially adapted to the agricultural machinery motor tricycle.

Along with Rural Economic Development improves constantly, the rural area uses motor tricycle more and more, also get more and more and lose the car phenomenon, cause very big economic loss and misery to the peasant, people had once developed some burglary-resisting installations for this reason, such as installing safety lock additional, preparation chain etc., but, still have to be pounded and ruined car phenomenon steathily because these equipment are firm inadequately.

The purpose of this utility model is exactly that the agricultural machinery anti-theft lock for vehicle that uses on a kind of novel agricultural machinery motor tricycle is provided at above-mentioned situation.

The purpose of this utility model is achieved like this, utilize the structural principle of existing safety lock to adopt new form of structure, promptly adopt the double structure form of the two tongues of twin-lock to manufacture with steel plate, the tapered end of one of them lock (dead bolt) is to be assemblied on shell one side, be set with holddown spring outward, tapered end is slided by cone control, another slide block of the locking restriction of the active receiving of cone.

The utility model structure uniqueness, sturdy and durable, theftproof performance is good, and is safe and reliable, easy to use.

Below in conjunction with accompanying drawing structure of the present utility model is elaborated.

Accompanying drawing is a structure chart of the present utility model.

As seen from the figure, structure of the present utility model is on inwall one side of shell 1 gathering sill 6 to be housed, be equipped with tapered end 2(or claim dead bolt by gathering sill is other), tapered end is two parts of mutual socket, tapered end is set with spring 3 outward, on the shell 1 inwall opposite side corresponding with tapered end with nut 12, gland 10 and nut 11 are equipped with screw rod 13 and swivel nut 9, handle 14 is housed on the screw rod 13, screw rod 8 is housed in the swivel nut 9, cone 4 is housed on the screw rod 8, pilot pin 5 and block 7 are arranged on the cone 4, cone 4 can be slided along gathering sill 6 front and back by pilot pin, thereby tapered end 2 is stretched out in the outer or withdrawal shell of shell, realize the purpose of lock car, be the security reliability of guaranteeing to lock, in the shell inboard that the screw rod 13 one side steel bodies that have handle 14 are done insurance lock body 15 is housed also, and fixed and limited by the dead bolt 21 on the 16 pairs of lock bodies of fixed head in the shell 1, screw rod 19 is housed on the dead bolt 21, screw end head has nut 20, slide block 18 is housed on the screw rod 19, and location-plate 17 is contained on the shell, and screw rod 19 passes in the hole, garden from the location-plate, screw rod 19 is fixed, and whole lock is sealing state.

The situation of installing and using of the present utility model is, the shell of lock is welded on the front fork under the direction handgrip, the lock shell is manufactured by the steel plate of 5 millimeters thick, be sealing one integral body, tapered end (dead bolt) the 2nd is manufactured with crude steel spare, so sturdy and durable, pound not bad not coming out, have good anti-theft effect, when needs lock car, be rotated counterclockwise handle 14, conehead 4 moves right, make tapered end 2 stretch out the lock shell up and down, stop that handlebar freely rotates, key is inserted in the lock body 15 again, be rotated counterclockwise, screw rod 19 promotes slide block 18 and moves right, and overlaps with block 7, reaches the effect that stops handle to rotate.The car direction can not freely be rotated, and also just can't advance, if turning handle by force, screw rod 13 is destroyed, and the ordinary circumstance lock of just not opening plays antitheft effect; In the time of need unblanking, key is inserted in the lock body 15, turn clockwise, slide block 18 is slided left screw rod 19 and block 7 breaks away from, rotary handle 14 again, screw rod 8 is being with cone 4 to left movement, and tapered end 2 is subjected to the pressure of spring 3 and in the lock housing of withdrawing, directional lever freely rotates and reaches the purpose of unblanking with car.

From the above, the utility model has been owing to adopted steel plate to do shell, and is welded under the direction handgrip; become one with car; and the two tongues of lock core employing twin-lock, thereby not only firm but also insure, no key is difficult to open; if lock is smashed; car also be cannot say for sure complete, and the auto theft people does not reach required purpose, thereby uses the utility model especially effectively to prevent to steal car; protect car owner's interests greatly, had remarkable social benefit and popularizing value.
