In the using process of the structure, a cavity needs to be formed in the door body, all the above-mentioned components except the locking plate 1 need to be arranged in the cavity, the fixedly arranged limiting disc 2, the guide disc 3 and the limiting block 4 need to be fixed on a bracket on the inner wall of the cavity of the door body, the inner side surface of the door needs to be provided with a waist hole annular opening with the shape consistent with that of the limiting ring groove 8, the force application shaft 9 extends out of the opening, the end part of the force application shaft is provided with a rotating handle, the manual operation consists in rotating the rotating handle to enable the force application shaft 9 to rotate while conducting periodic revolution under the guiding of the limiting ring groove 8 and the inner teeth 11, the purpose of the rotation is to enable the shifting rod 14 to be extruded on the shifting piece 15 to enable the sliding block 5 to transversely slide, the revolution aims to change the height position to switch the shifting rod 14 to the sliding block 5 for shifting, and aims to enable the unidirectional movement of the force application shaft 9, can also increase a ratchet between twist grip and the application of force axle 9 for twist grip can only drive application of force axle 9 when just corotating and rotate, can not produce the drive effect during the reversal, and specific function process can see below:

as shown in fig. 1 and 2, in order to gradually insert the latch 6 into the lock hole 7, the force application shaft 9 is rotated counterclockwise, the driving gear 12 moves downward along the internal teeth 11 during counterclockwise rotation, and simultaneously, the dial 13 gradually presses the paddle 15 on the right side of the slider 5 at the height position during rotation, but the slider 5 is limited laterally and then the slider 5 moves rightward, the latch 6 on the right side of the slider 5 is inserted into the lock hole 7, fastening is completed, the force application shaft 9 moves downward along with the driving gear 12, the height position of the dial 13 also lowers to the position of the second slider 5, then the dial 14 just rotates along with the dial 13 and then abuts against the right paddle 15 of the second slider 5 and presses rightward, so the latch 6 on the slider 5 at the height position is also inserted into the lock hole 7, after that, each time the force application shaft 9 moves down to a position, the poking rod 14 pushes the poking piece 15 out of the position to the right, and the process of sequentially inserting the bolt 6 into the lock hole 7 from top to bottom is realized, because the process is completed one by one, the manual operation is not very difficult, the continuity of the whole process is good, the operability is simple, all the movements are actually generated after the force application shaft 9 rotates in the anticlockwise direction, and the driving element is only the force application shaft 9, so the structure is simple.

As shown in fig. 3 and 4, each lock tongue 6 needs to be retreated from the lock hole 7 before the door is opened, the design skillfully utilizes a circulation mode to realize the retreating process, the force application shaft 9 continues to rotate anticlockwise, the driving gear 12 continues to step along with the internal teeth 11, only at this time, the step path is changed from top to bottom to top, the dial plate 15 pushes the left-side dial plate 15 after the dial plate 13 rotates, so that the left-side dial plate 15 is leftwards moved to drive the slide block 5 to move leftwards, the lock tongue 6 retreats from the lock hole 7 after the slide block 5 moves leftwards, the same force application shaft 9 sequentially passes through the left-side dial plate 15 to shift the slide block 5 leftwards in the gradually rising process, and each lock tongue 6 retreats from the respective lock hole 7 to complete the separation.

Before implementation, except design and calculation, simulation experiments and entity experiments are needed as necessary, the transverse distance between the two shifting pieces 15, the length of the shifting rod 14 and the transverse distance between the left side and the right side of the limiting ring groove 8 are well debugged, and the structure can be smoothly realized as long as the three numerical values are well controlled.

By adopting the form of the internal teeth 11, the motion track of the driving gear 12 is always positioned in the kidney-shaped hole, so the space utilization rate is higher, the cavity of the door body can be opened smaller, and the strength of the door body cavity is smaller, so that the door body cavity is better.
