The side of the gear sleeve 23 is provided with two first movable grooves 24 arranged oppositely. The gear sleeve 23 is installed in the mounting groove 13. One end of the outer lock rotating shaft 21 extends into the gear sleeve 23. The outer lock rotating shaft 2 1 extends out of the lock body 10 from the circular hole 14, the ball 50 is movably accommodated in the first movable groove 24, a boss 22 is provided on the outer lock rotating shaft 21, the gear sleeve 23 can rotate relative to the lock body 10, and the outer lock rotating shaft 21 can rotate relative to the gear sleeve 23. When the outer lock rotating shaft 21 is rotated, the ball 50 is pushed into the first displacement groove 11 through the boss 22. At this time, half of the ball 50 is accommodated in the first displacement groove 11, and the other half is accommodated in the first movable groove 24, so that the gear sleeve 23 is locked, and the gear sleeve 23 can no longer rotate relative to the lock body 10. The lock core for the sliding door with a ball stop lock also includes a safety switch 25 and a switch spring 42. The safety switch 25 is provided with a second displacement groove 26, and the lock body 10 is also provided with a second movable groove 12. One end of the switch spring 42 is in contact with the safety switch 25, and the other end of the switch spring 42 is in contact with the side wall of the lock body 10. Pressing the safety switch 25 squeezes the switch spring 42 to contract, and the second displacement groove 26 can be connected to the second movable groove 12. The lock core for the sliding door with the ball stop lock also includes an inner lock rotating shaft 27, and the gear sleeve 23 is installed between the outer lock rotating shaft 21 and the inner lock rotating shaft 27 and is simultaneously engaged and connected with both; the lock core for the sliding door with the ball stop lock also includes two eagle-shaped lock hooks 28, and the eagle-shaped lock hooks 28 are provided with mounting rotation holes 29, and the lock body 10 is also provided with a perforated mounting shaft 17, and the perforated mounting shaft 17 passes through the mounting rotation hole 29, and the eagle-shaped lock hooks 28 can rotate with the perforated mounting shaft 17 as the rotation center. The lock core for the wave ball stop lock sliding door also includes a first drive link 31, a second drive link 33, and a positioning shaft 37. The first drive link 31 and the second drive link 33 are both meshed and connected with the gear sleeve 23. The first drive link 31 and the second drive link 33 are both provided with a limiting groove 34. The perforated mounting shaft 17 passes through the limiting groove 34. The positioning shaft 37 is fixedly installed on the first drive link 31 and the second drive link 33.The ball ball stop lock for sliding door lock core also includes a connecting screw 55, and the connecting screw 55 is fixedly mounted on the screw of the first driving link 31 or the second driving link 33. The lock body 10 is provided with a positioning guide groove 16, and the eagle-shaped lock hook 28 is provided with an L-shaped groove 30, and the end of the positioning guide groove 16 is a groove 18, and the positioning shaft 37 passes through the L-shaped groove 30 and extends into the positioning guide groove 16.
[0030] In this embodiment, the circular hole 14 is an assembly hole for the lock body 10 and the outer lock rotating shaft 21. The inner diameter of the circular hole 14 matches the outer diameter of the outer lock rotating shaft 21. The other end of the outer lock rotating shaft 21 is installed in the inner control of the gear sleeve 23. The ball 50 is installed in the first movable groove 24 and rotates axially with the gear sleeve 23. When the gear sleeve 23 rotates to a certain angle and reaches the lock hook working position and stops rotating, the ball 50 just stays on the lock body 1 0, at this time, the gear sleeve 23 cannot rotate, but the outer lock rotating shaft 21 can still rotate a certain angle in the gear sleeve 23, and the outer lock rotating shaft 21 is provided with a boss 22 that can push the wave ball 50 out, and there is a locking point on the boss 22. If the outer lock rotating shaft 21 continues to rotate, the boss 22 will push the wave ball 50 into the first displacement groove 11 of the lock body 10, and the outer lock rotating shaft 21 will also reach the stop rotation point and cannot continue to rotate. At this time, the wave ball 50 in the first movable groove 24 simultaneously blocks the gear sleeve 23 and the lock body 10, that is, half of the wave ball 50 is in the first movable groove 24 on the gear sleeve 23, and the other half of the wave ball 50 is in the first displacement groove 11 of the lock body 10, so that the two become a whole, and mechanical external force cannot cause the two to rotate and separate. Only by using a key to rotate the outer lock rotating shaft 21 and turn the boss 22 on the outer lock rotating shaft 21 to a certain angle, the ball 50 can leave the first displacement groove 11. The inner lock rotating shaft 27 is axially coupled with the outer lock rotating shaft 21 by a step, so the inner lock rotating shaft 27 can also be rotated by a key, thereby driving the outer lock rotating shaft 21 to rotate, and the boss 22 on the outer lock rotating shaft 21 leaves the first displacement groove 11 of the lock body 10, thereby realizing the unlocking function.
[0031] In this embodiment, the safety switch 25 is designed with a stop structure. In the initial state of this stop structure, a notch groove 56 on the gear sleeve 23 blocks one side of the ball 50, and the other side of the ball 50 hits the solid surface of the safety switch 25. In this way, the gear sleeve 23 cannot rotate due to the obstruction of the ball 50, and the safety switch plays the role of a safety protection lock hook. When the safety switch 25 is pressed, the switch spring 42 is squeezed, and the second displacement groove 26 on the safety switch 25 is aligned with the second movable groove 12 on the lock body 10. At this time, if the gear sleeve 23 is rotated, the ball 50 can be squeezed and moved into the second displacement groove 26 of the safety switch 25. The gear sleeve 23 is not blocked by the ball 50 and can rotate smoothly, thereby driving the connecting rod to move, realizing the function of the eagle-shaped lock hook 28 of the door lock rotating outward and locking the buckle plate. When the door lock is opened again and the lock hook 28 is reset, the gear sleeve 23 is also reset to the original state. At this time, the safety switch 25 is pushed against the side of the lock body 10 under the elastic force of the switch spring 42. The second displacement groove 26 on the safety switch 25 is pushed out of the second movable groove 12 by the spring thrust. At the same time, the ball 50 is squeezed into the second movable groove 12 by the side of the safety switch 25. The notch groove 56 on the gear sleeve 23 cannot rotate because of the obstruction of the ball 50. There is a notch groove 56 on the gear sleeve 23 for the ball 50 to block. When the safety switch 25 is bounced to the free state by the spring, the ball 50 just supports the notch groove 56. Therefore, the gear sleeve 23 cannot rotate. In addition, the notch groove 56 plays a positioning role when assembling the lock body parts. The assembly is more accurate.
[0032] This ball-stop lock for sliding doors is mainly used on sliding doors, especially on balcony sliding doors. Figure 7As shown, the ball ball stop lock for sliding door is fixed on the sliding door 60 by screws, and is fixedly installed on the indoor side. A D-shaped handle 61 is generally installed indoors. An external handle 62 is first installed on the outdoor side of the door. The external handle 62 passes through the hole of the ball ball stop lock for sliding door with a hole to install the rotating shaft 17 through a screw 63a, and the locking screw 63a is tightened to the screw column 62a of the external handle 62. The D-shaped handle 61 is connected to the screw hole 53 of the lock core by a connecting screw 63b, and the transverse screw is tightened. The D-shaped handle 61 is fixed to the lock body and the external handle 62 is fixed to the sliding door 60. A buckle plate 65 is fixedly installed on the side of the door frame 64 by two screws, and the lock hook hooks the buckle plate 65 lock tongue when the lock is closed. A push-twist 61a is provided on the D-shaped handle 61, and the push-twist 61a and the connecting screw 55 are linked together through a linkage design. Push the push button 61a upward, one of the driving links moves upward, pushes the lock hook, and finally pushes one lock hook out of the lock body 10. The other driving link moves downward, and also pushes the other lock hook, and finally pushes the other lock hook out of the lock body 10, so that the two lock hooks can be linked to lock the buckle plate 65. After the lock hook locks the buckle plate 65, the best state is that the lock hook cannot move when the lock hook is pushed. Even when such a lock is locked without a key, it is very difficult to pry open the door lock outdoors. That is to say, it is required to use a key to unlock the door outdoors. The design of the L-shaped groove of the lock hook of the present invention realizes the self-locking function. The push button link 66 is connected to the connecting screw 55 assembled with the first driving link 31, and the connecting screw 55 drives the first driving link 31 to move. After the positioning shaft 37 on the first driving link 31 pushes the lock hook to lock, it moves to a limited position. If the lock hook is pulled by force, the positioning shaft 37 will be displaced into the groove 18 of the lock body 10. Thereby, the rotation of the lock hook is blocked in the reverse direction. Pushing the push button 61a downward will cause the door to move in the opposite direction, thus realizing the function of opening the lock body 10. After pushing the push button 61a upward, we need a locking function, that is, the door lock can only be opened with a key even in the room, and the push button 61a cannot be pushed. Therefore, the lock body 10 is designed with the function of locking the lock body 10 with internal and external locks. Customers can choose the internal lock or the external lock according to their own needs, or the unlocking function is required for both the internal and external locks, that is, the lock hook is locked, and the lock hook cannot be driven by pushing the connecting rod. The present invention couples the rotating shaft of the external lock 67a with the rotating shaft of the internal lock 67b after rotating a certain angle. At the same time, the rotating shaft of the external lock 67a and the gear sleeve are also designed with axial steps, and they can only contact after rotating a certain angle. In this way, it can be ensured that both the internal and external locks have a certain degree of freedom. After closing the locking lock, it is necessary to reverse 180 degrees to pull out the key. At this time, the gear sleeve is still positioned in a locked state.
[0033] Furthermore, a torsion spring fixing hole 32 is provided on the first driving connecting rod 31, and the ball stop lock sliding door lock core also includes an elastic torsion spring 38. A fixing column 15 is also provided on the lock body 10, and the elastic torsion spring 38 is sleeved on the fixing column 15, and the end of the elastic torsion spring 38 is inserted into the torsion spring fixing hole 32.
[0034] In this embodiment, the elastic torsion spring 38 is a 130-degree torsion spring, which can help push the first driving connecting rod 31, so that the user can save more effort and feel more comfortable when driving the first driving connecting rod 31.
[0035] Furthermore, the lock body 10 is provided with a first through slot 19 and a second through slot 20, the safety switch 25 passes through the second through slot 20, and the eagle-shaped lock hook 28 can pass through the first through slot 19. The first driving connecting rod 31 and the second driving connecting rod 33 are both provided with a toothed edge 36, and the toothed edge 36 is meshed with the gear on the gear sleeve 23.
[0036] In this embodiment, the gear sleeve 23 can drive the first driving connecting rod 31 and the second driving connecting rod 33 by rotating.
[0037] Furthermore, the ball ball stop lock for sliding door lock core also includes a cover plate 39, and the cover plate 39 is fixedly arranged above the lock body 10. The cover plate 39 is provided with a first through hole 40, a second through hole 41 and a third through hole 51, the inner lock head rotation shaft 27 passes through the outer surface of the cover plate 39 from the first through hole 40, and the holed installation shaft 17 passes through the outer surface of the cover plate 39 from the second through hole 41. The screw hole for installing the first drive connecting rod or the second drive connecting rod has a boss shaft 52, and the boss shaft 52 passes through the third through hole 51. The connecting screw 55 is fixed to the screw hole of the first drive connecting rod or the second drive connecting rod. The hole on the push button connecting rod is sleeved on the connecting screw 55, so as to realize the function of the push button pushing the connecting rod and driving the lock hook.
[0038] In this embodiment, the cover plate 39 covers the entire lock body 10 and is fixed to the lock body by screws passing through the screw holes of the lock cover. At the same time, the boss shaft on the connecting rod moves longitudinally in the third through hole 51. When the lock hook is locked, the boss shaft 52 on the driving connecting rod is clamped in the third through hole 51 of the lock cover when the lock hook is pried back, thereby enhancing the precision of the lock body, increasing the stability of the internal structure, and effectively ensuring the strength of the lock body.
[0039] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
