[0019] See also Figures 1 - 4The utility model provides a technical solution: a lock body safety tongue locking device, including a lock body plate 1, a locking rod 1 2, a locking rod 2 3, a lock plate 4, a lock tongue 5, a sealing gasket 501, a ball 502, a spring 503, a limiting groove 504, a placement hole 505, an inclined groove 506 and a fixing plate 6, a locking rod 1 2 and a locking rod 2 3 are arranged on the top of the lock body plate 1, a locking plate 4 is arranged on the left side of the surface of the lock body plate 1, a lock tongue 5 is arranged on the right side of the surface of the lock body plate 1, and a locking rod 1 2 and a locking rod 2 3 are arranged on the top of the lock body plate 1. A 2 is connected to the lock tongue 5, and the upper locking rod 3 is connected to the lock plate 4. Placement holes 505 are provided on the left and right sides of the lock tongue 5, and a spring 503 is placed inside the placement hole 505. The other end of the spring 503 is in contact with the ball 502. A limiting groove 504 is provided at the end of the placement hole 505, and a sealing gasket 501 is placed at the end of the placement hole 505. An inclined groove 506 is provided on one side of the sealing gasket 501. Fixed plates 6 are provided on the left and right sides of the surface of the lock body plate 1.

[0020] As the first embodiment of the utility model: a card slot is provided at the bottom of the inner side of the placement hole 505, and the inner side of the card slot is connected to the other end of the spring 503. This design plays a role in fixing the top spring 503 to prevent the spring 503 from shaking inside the placement hole 505. The inner side of the limiting groove 504 matches the outer side of the sealing gasket 501. The surface of the limiting groove 504 is provided with a plurality of internal threads. The surface of the sealing gasket 501 is penetrated with a plurality of bolts, and the bolts are meshed with the plurality of internal threads provided on the surface of the limiting groove 504. This design plays a role in sealing the spring 503 and the ball bearing. The function of 502 is that the inside of the inclined groove 506 is in contact with the outside of the ball 502, and this design makes it convenient for the ball 502 to be stuck in the inside of the lock frame. The sealing gasket 501 is made of brass. This design can extend the service life of the sealing gasket 501. The length of the spring 503 is equal to the length of the placement hole 505. The diameter of the inside of the placement hole 505 is larger than the diameter of the ball 502. This design makes it convenient for the ball 502 to bounce up and down inside the placement hole 505. The inside of the placement hole 505 is polished to a smooth surface. This design reduces the friction between the ball 502 and the inside of the placement hole 505.

[0021] As a second embodiment of the present utility model: first, the lock body plate 1 is vertically placed on one side of the door panel, and the surface of the fixing plate 6 is passed through a plurality of studs to fix it to the door panel. Then, the lock frame is taken and fixed to one side of the door frame, and then the lock frame is matched with the lock tongue 5 and the lock plate 4 provided on one side of the lock body plate 1. After the lock body plate 1 and the door panel are fixed, the upper locking rod 2 drives the lock tongue 5 to move toward the inside of the lock body plate 1 by turning the door handle. At this time, the door panel and the door frame are overlapped, and the door handle is released to make the lock tongue 5 bounce into the inside of the lock frame. The balls 502 placed in the placement holes 505 provided on the left and right sides of the lock tongue 5 are bounced up under the action of the spring 503, so that the spring 503 pushes the balls 502 to contact with the inside of the lock frame, so that the lock tongue 5 can be inserted into the lock frame. The interior of the door panel will not produce a slight shake. Multiple bolts inserted through the surface of the sealing gasket 501 are engaged with multiple internal threads opened on the surface of the limiting groove 504. At this time, the spring 503 and the ball 502 will not be separated from the interior of the placement hole 505, which is conducive to the bouncing of the ball 502 back and forth inside the placement hole 505. At this time, through the action of the spring 503, the ball 502 will contact all the inclined grooves 506 of the sealing gasket 501, so the ball 502 can dock with the inside of the lock frame. This design enables the spring 503 placed inside the placement hole 505 to push the ball 502 to move to the inside of the lock frame, so that the ball 502 can contact the inside of the lock frame, so that the safety tongue 5 will not shake inside the lock frame.
