Detailed Description

The invention will be further described in detail with reference to the following examples:

example 1:

the vehicle body locking device shown in fig. 1 to 4 includes a locking bracket, a locking handle 9, and a chain unit; the locking support comprises a bottom plate 1, two parallel and symmetrical positioning plates 2 are arranged upwards on the bottom plate 1, a plurality of positioning holes 3 are arranged at equal intervals on the positioning plates 2, a fixing plate 4 parallel to the positioning plates 2 is arranged upwards on one side of the two positioning plates 2 on the bottom plate 1, and a plurality of limiting grooves 5 corresponding to the positioning holes 3 are formed in the fixing plate 4; the locking handle 9 comprises a cross rod, and an upper vertical rod and a lower vertical rod are respectively arranged at two ends of the cross rod; the chain unit comprises a ring chain 6 and a lock hook 7 arranged at the front end of the ring chain 6, and the rear end of the ring chain 6 is fixedly connected with the positioning hole 3 of the locking support through a lower vertical rod of a locking handle 9.

A plurality of liquid draining holes 10 are arranged between the two positioning plates 2 on the bottom plate 1; the lock hook 7 is connected with the front end of the loop chain 6 through a shackle 8; two ends of the locking bracket are provided with connecting plates 11 which are fixedly connected with the pry body 12, and the connecting plates 11 are provided with connecting holes for mounting connecting pieces; the front end of the locking hook 7 is provided with a hook part 7-1.

Example 2:

as shown in fig. 5, the front end of the latch hook 7 of the chain unit is provided with a bent portion 7-2; other features are the same as those of embodiment 1.

As shown in FIG. 6, when the invention works, the locking bracket is pre-installed on the pry body 12, and the connecting plates 11 at the two ends of the locking bracket are fixedly connected with the pry body 12 through connecting pieces; when the prying body 12 with the vehicle body 13 reaches the locking station, an operator hangs the lock hook 7 of the chain unit into the corresponding technical hole in the vehicle body 13, then tightens the rear end of the loop chain 6, selects the positioning hole 3 on the locking support which is matched with the loop chain 6, inserts the lower vertical rod of the locking handle 9 into the positioning hole 3 in which the loop chain 6 is parallel to the two positioning plates 2, presses the upper vertical rod of the locking handle 9 into the limiting groove 5 after rotating around the axis of the lower vertical rod through the cross rod, and finishes the locking operation.
