Description

The agricultural three-wheel transporter lock

The utility model is about lock, particularly about the invention of agricultural three-wheel transporter lock.

Present agricultural three-wheel transporter does not have special anti-theft device, under unserviced situation, just car can be pushed away away with manpower, very easily loses.

The purpose of this utility model provides a kind of simple and easy, special-purpose lock easily, is loaded on the preceding screw of agricultural three-wheel transporter check mechanism fixed head, with key operated and locking.

For achieving the above object, the utility model adopts following technical scheme: this lock is made up of lock body, lock bridge, lock core; Lock core is fixed on the lock body; One end of cylindrical helical body and lock core are fixedly connected and are integral, and its other end is close to lock bridge; Spring one end is fixed on the lock bridge, and the other end is fixed on the lock body; Installing plate is fixed on the lock body outside.

This lock is installed in the preceding screw of agricultural three-wheel transporter check mechanism fixed head.During locking, lock bridge stretches out, and pins braking thick stick plate axle.

This lock simple installation, rational in infrastructure, convenient and practical, in case locking is difficult for lock is opened with external force, the insurance theftproof is good.

Below in conjunction with accompanying drawing the utility model is described in further detail:

The sectional view of front view when Fig. 1 is this lock unlatching.

The sectional view of vertical view when Fig. 2 is this lock unlatching.

Right view when Fig. 3 is this lock unlatching.

The sectional view of front view when Fig. 4 is this lock locking.

The sectional view of vertical view when Fig. 5 is this lock locking.

As shown in Figure 1 and Figure 2, this lock is made up of lock body 6, lock bridge 5, lock core 12.Screw 24 joins lock core 12 and cushion block 11 together, and is porose 10 on the cushion block 11, by these hole 10 usefulness screws cushion block 11 and lock body 6 joined together.One end of cylindrical helical body 9 is fixedly connected by screw 14 and lock core 12 and is integral, and its other end is close to lock bridge 5.Spring leaf 25 1 ends are close to cylindrical helical body 9, and the other end passes the hole 23 on the lock core 12.One end of spring 15 is fixed on the lock bridge 5 by screw 17, pad 16, and the other end is fixed on the lock body 6 by bolt 26, nut 27.Porose 7 on the baffle plate 8, hole 21, hole 22 are fixedly connected baffle plate 8 and lock body 6 sides by hole 7 usefulness screws; By hole 21, hole 22, with screw with plate washer 8 be fixedly connected above the lock body 6.Cylinder 20 is fixed on the lock bridge 5 by hole 18 usefulness screws and lock body 6 cylinder 19 that has been fixedly connected; Spring leaf 2 is walked around post 20, and the other end is blocked by cylinder 19.Installing plate 1 is fixedly connected with lock body 6 by bolt 3, nut 4.

During locking, key 13, lock core and cylindrical helical body rotate simultaneously, thereby promote the protruding lock body of an end of lock bridge, and when the other end was close to plate washer, this lock was in latched position, as Fig. 4, shown in Figure 5.During unlatching, key 13, lock core and cylindrical helical body rotate simultaneously, and lock bridge rebounds under the elastic force acting in conjunction of spring 5 and spring leaf 2, and this lock is in the enable possition, as shown in Figure 1 and Figure 2.Can be in unlatching or lock-out state by this lock of perception by spring leaf 25.

This lock is installed in the preceding screw of agricultural three-wheel transporter check mechanism fixed head by installing plate.During locking, lock bridge stretches out, and pins braking thick stick plate axle.
