Referring to fig. 1 to 7, there is illustrated a slide lock type key mainly including: buckle body track 1, lock body 2 and lock core 3, wherein:

referring to fig. 1, the buckle track 1 includes a first slide bar 14 and a second slide bar 15 parallel to each other, and the upper ends of the first slide bar 14 and the second slide bar 15 are connected by a connecting portion 16, and the lower ends of the first slide bar 14 and the second slide bar 15 are connected by the connecting portion 16, so as to form a ring-shaped buckle track 1. The connecting portion 16 may have an arc shape or a linear shape. It should be understood that the above is to divide the buckle track 1 into a plurality of parts for convenience of description, and therefore, the buckle track 1 may be a unitary structure, that is, a metal round bar may be bent into a structure as shown in the buckle track 1 in fig. 1.

Referring to fig. 2 and 3, the first sliding rod 14 is shown to have an opening 4 (i.e. the first sliding rod is formed by removing a section), the second sliding rod 15 has a longitudinal first limiting groove 5 on its inner side wall surface, the first limiting groove 5 is located on the opposite side of the opening 4, the bottom surface of the first limiting groove 5 extends from the inner wall surface of the second sliding rod 15 to the inside of the sliding rod in an inclined manner, and the top surface of the first limiting groove 5 is a horizontal surface, so that the third round ball 12 can enter or exit from the first limiting groove 5.

Referring to fig. 4 to 7, the lock body 2 has a circular passage 17 longitudinally distributed on both left and right sides, and the circular passage 17 penetrates through the lock body 2. The first sliding rod 14 and the second sliding rod 15 are round rods and are located in the round channels 17, so that the lock body 2 is sleeved on the first sliding rod 14 and the second sliding rod 15 and can slide up and down along the sliding rods under the pushing of fingers, and the opening 4 is opened or sealed.

Furthermore, a sliding groove 6 parallel to the first sliding rod 14 and the second sliding rod 15 is formed in the surface of the lock body 2, and the sliding groove 6 longitudinally penetrates through the lock body 2. The left and right inner walls of the sliding groove 6 are both arc structures 19 protruding outwards, so as to form a sliding rail for the lock cylinder 3 to slide. Besides, the left and right inner walls of the sliding groove 6 are both outward-protruding rectangular or ">" shaped structures, which have similar functions to the circular arc-shaped structures, and mainly can connect the lock cylinder 3 in the sliding groove 6 and can slide up and down along the sliding groove 6.

And a second limiting groove 7 and a first channel 8 with flush bottom surfaces are respectively formed in the left inner wall and the right inner wall of the sliding groove 6, and the height of the second limiting groove 7 is greater than that of the first channel 8. The left side wall and the right side wall of the lock cylinder 3 are both groove structures 20 corresponding to the convex arc-shaped, rectangular or '>' shaped structures, so that the left side wall and the right side wall of the lock cylinder 3 are respectively connected with the left inner wall and the right inner wall of the sliding groove 6 in a sliding manner.

The outer surface of the lock core 3 is an arc surface protruding outwards so that fingers can push the lock core. A second channel 9 which transversely penetrates through is formed in the lock cylinder 3, the height of the second limiting groove 7 is larger than that of the second channel 9, and the first channel 8 and the second channel 9 are the same in height. The length of the lock cylinder 3 is the same as that of the sliding groove 6, when the lock cylinder 3 is completely positioned in the sliding groove 6, the second channel 9 is communicated with the upper part of the second limiting groove 7, and the first channel 8 is positioned below the first channel 8. A first round ball 10 is arranged between the second channel 9 and the first limiting groove 5, a second round ball 11 and a third round ball 12 are arranged in the second channel 9, and the diameter of the third round ball 12 is larger than the width of the first channel 8. The first round ball 10 and the second round ball 11 are connected by a horizontally arranged elastic part 13 so as to define the relative position between the first round ball 10 and the second round ball 11. The first round ball 10, the second round ball 11 and the third round ball 12 are all steel balls, and the elastic part 13 is a metal spring. It should be understood that the first channel 8 and the second channel 9 may be circular channels or square channels, and the main important function is to provide the proper horizontal movement of the round balls therein.

In addition, referring to fig. 8, the left and right sides of the lock body 2 may also be arc-shaped grooves 18, such as semicircular grooves, etc., and the first sliding bar 14 and the second sliding bar 15 are round bars which are located in the arc-shaped grooves 18, so that the lock body 2 can slide along the sliding bars.

Referring to a-c in fig. 9, the operation principle of the slide lock type key is as follows: referring first to a in fig. 9, which is a state that the lock body 2 closes the opening 4 on the first slide bar 14, at this time, the first round ball 10 is located at an interface between the second channel 9 and the first limit groove 5, and during the process that the lock cylinder 3 moves up and down along the slide groove 6, the first round ball 10 always moves up and down along the second channel 9 under the constraint of the first channel 8. The second ball 11 is always located in the first channel 8. The third round ball 12 plays a role in limiting the lock cylinder 3 to continue moving upwards at the interface of the first channel 8 and the second limiting groove 7, the process of the up-and-down movement of the lock cylinder 3 is summarized, and the third round ball 12 is switched back and forth between the first channel 8 and the interface of the first channel 8 and the second limiting groove 7.

When the opening 4 needs to be opened, as shown in b in fig. 9, the lock cylinder 3 is moved downward first, and when the lock cylinder 3 moves downward along the sliding slot 6 until the first channel 8 and the second channel 9 are aligned, the lock cylinder 3 cannot move downward continuously due to the limitation of the bottom of the second limiting slot 7 on the first round ball 10. Then the lock body 2 is pushed to move downwards, the first limit groove 5 with the inclined bottom surface is matched under the pushing of the wall surface of the right side wall of the lock body 2, the third round ball 12 at the interface of the first channel 8 and the second limit groove 7 is pressed into the second channel 9, the limit of the third round ball 12 on the lock body 2 is removed, the lock body 2 can continue to move downwards along with the lock cylinder 3, and the opening 4 is opened (refer to c in fig. 9).

When the opening 4 needs to be closed (refer to c in fig. 9, b in fig. 9, and a in fig. 9 in sequence), the lock body 2 is pushed upwards to the opening 4, then the lock cylinder 3 is pushed upwards, the right portion of the third round ball 12 enters the interface between the first channel 8 and the second limiting groove 7 under the pushing of the right side surface of the lock cylinder 3, and when the lock cylinder 3 continues to move upwards until the first round ball 10 reaches the top surface of the second limiting groove 7 and is clamped, the lock cylinder 3 cannot continue to move upwards. Meanwhile, the third round ball 12 is limited at the interface of the first channel 8 and the second limiting groove 7 under the action of the wall surface of the right side wall of the lock core 3, so that the lock body 2 cannot move upwards continuously, and the lock body 2 can seal the opening 4.

Finally, it should be understood that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention. Although the present invention has been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without inventive work are still within the scope of the present invention.
