DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Please refer to Figs. 1-3 The utility model provides a kind of technical scheme: a kind of two-sided lock point's plug-in open type ball lock cylinder structure, it include: shell 1 and key body 4, the inside of shell 1 is equipped with lock cylinder body 2, the top of lock cylinder body 2 is equipped with keyhole 3, key body 4 is inserted into keyhole 3;

[0026] The surface of key body 4 is provided with sawtooth bar 5, the middle of lock cylinder body 2 is equipped with through slot 6, the inside of through slot 6 is provided with upper movable block 7 and lower movable block 8, the inner wall of upper movable block 7 is equipped with first fixed block 9, the inboard of lower movable block 8 is equipped with second fixed block 10, the side of upper movable block 7 and lower movable block 8 is equipped with first protrusion 11 and second protrusion 12 respectively, the inboard of shell 1 is equipped with notch 13, movable spring 14 is arranged between first protrusion 11 and second protrusion 12, notch 13 is symmetrically equipped in the two sides of shell 1, notch 13 and shell 1 are integrally formed structure between, the first protrusion 11 of side of upper movable block 7 and the second protrusion 12 of side of lower movable block 8 are symmetrically arranged, upper movable block 7, first fixed block 9 and first protrusion 11 are integrally formed structure, lower movable block 8, second fixed block 10 and second protrusion 12 are integrally formed structure, the first fixed block 9 of inboard of upper movable block 7 and the second fixed block 10 of inboard of lower movable block 8 are symmetrically arranged on the same side of key body 4, upper movable block 7, lower movable block 8 and the through slot 6 of lock cylinder body 2 form telescopic structure, through slot 6 is evenly equipped with multiple groups along the vertical direction of lock cylinder body 2, the inside of each group of through slot 6 is symmetrically equipped with upper movable block 7 and lower movable block 8, key body 4 penetrates the hollow slot in the middle of upper movable block 7 and lower movable block 8, upper movable block 7, lower movable block 8 and the notch 13 of shell 1 inner wall are matched.

[0027] In the implementation, when the lock is opened, the corresponding key body 4 is inserted into the key hole 3, so that the serrated strips 5 on the side of the key body 4 are in abutment with the first fixed blocks 9 and the second fixed blocks 10 on the inner walls of the upper movable blocks 7 and the lower movable blocks 8. When the key body 4 is inserted, the protruding portions of the serrated strips 5 on the side of the key body 4 will respectively press the first fixed blocks 9 and the second fixed blocks 10, so that the first fixed blocks 9 and the second fixed blocks 10 move towards each other. The first fixed blocks 9 are installed on the inner side of the upper movable blocks 7, and the second fixed blocks 10 are installed on the inner side of the lower movable blocks 8. Therefore, the mutual approaching movement of the first fixed blocks 9 and the second fixed blocks 10 will cause the upper movable blocks 7 and the lower movable blocks 8, which are designed to be staggered, to move towards each other and be retracted into the lock body 2 along the through grooves 6 of the lock body 2. When the upper movable blocks 7 and the lower movable blocks 8 move towards each other, the first protrusions 11 on one side of the upper movable blocks 7 and the second protrusions 12 on one side of the lower movable blocks 8 will also move towards each other, thereby pressing the movable springs 14 between the first protrusions 11 and the second protrusions 12. Repeating the above steps will cause the upper movable blocks 7 and the lower movable blocks 8 in the remaining three groups of lock bodies 2 to be retracted into the through grooves 6 of the three groups of lock bodies 2. At this time, the upper movable blocks 7 and the lower movable blocks 8 are not in abutment with the notches 13 on the inner side of the shell 1, thereby achieving the effect of unlocking.

[0028] When locking is needed, the key body 4 is pulled out of the key hole 3 in the lock body 2. At this time, the first fixed blocks 9 and the second fixed blocks 10 on the inner walls of the upper movable blocks 7 and the lower movable blocks 8 are not pressed by the serrated strips 5 on the side of the key body 4. Then the movable springs 14 will reset and push the first protrusions 11 and the second protrusions 12 to move to both sides. When the first protrusions 11 move, they will drive the upper movable blocks 7 to move to one side, and the second protrusions 12 will drive the lower movable blocks 8 to move to the other side. The upper movable blocks 7 and the lower movable blocks 8 will move out of the through grooves 6 of the lock body 2 and be in abutment with the notches 13 on the inner side of the shell 1. At the same time, the upper movable blocks 7 and the lower movable blocks 8 in the remaining three groups of lock bodies 2 will also move out of the through grooves 6 of the lock body 2. They are limited by the notches 13 on the inner side of the shell 1, thereby achieving the effect of locking. Since the upper movable blocks 7 and the lower movable blocks 8 move to both sides respectively, the lock body 2 has a structure with two locking points.

[0029] Referring to Figs. 1-3It can be known that, in use, only the key body 4 is inserted into the lock core body 2, so that the serrated strips 5 on the side of the key body 4 extrude the first fixed block 9 and the second fixed block 10, and drive the upper movable block 7 and the lower movable block 8 to retract into the through slot 6 of the lock core body 2, and the first protrusion 11 and the second protrusion 12 extrude the movable spring 14, so as to realize the unlocking function, on the contrary, after the key body 4 is pulled out, under the action of the movable spring 14, the first protrusion 11 and the second protrusion 12, the upper movable block 7 and the lower movable block 8 will move out of the lock core body 2, so as to realize the locking function, which is convenient for the user to operate, and since the entire lock core body 2 does not need to be rotated, friction between the lock core body 2 and the shell 1 is avoided, so as to increase the service life of the lock core body 2.

[0030] In summary, the plug-in and open type ball lock core structure with two-sided locking points only needs to insert the corresponding key body 4 into the lock core body 2 through the key hole 3, and make the upper movable block 7 and the lower movable block 8 retract into the inside of the lock core body 2, so as to realize the unlocking function, on the contrary, after the key is pulled out, the movable spring 14 pushes the upper movable block 7 and the lower movable block 8 to butt joint into the notch 13 of the shell 1, so as to realize the locking function, which is the use feature of the plug-in and open type ball lock core structure with two-sided locking points, and the contents not described in detail in the description belong to the prior art known to the person skilled in the art.

[0031] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
