DETAILED DESCRIPTION

[0020] In order to clearly illustrate the specific implementation method, structure and effect of the present invention, an embodiment is provided and described as follows with the accompanying drawings:

[0021] The directions "front", "rear", "up", "down", "left", "right" and so on involved in the present invention are only for the convenience of understanding. The present invention is not limited to these directions, but can be adjusted according to actual conditions. In the present invention, the insertion direction of the first movable folding piece 51 into the lock body 10 (i.e., the Y-axis direction) is the up-down direction, the insertion direction of the key 70 (i.e., the Z-axis direction) is the left-right direction, and the rotation direction of the locking sleeve 12 (i.e., the X-axis direction) is the front-back direction.

[0022] See also Figures 1 to 6 The utility model provides a folding lock, which has a lock body 10, a folding sheet set 50 and an assembly 60. The folding sheet set 50 has a first movable folding sheet 51, a second movable folding sheet 53 and a plurality of middle folding sheets 52 connected to each other. The second movable folding sheet 53 is connected to the lock body 10 through the assembly 60. The plurality of middle folding sheets 52 can be in a folded or unfolded state, and the first movable folding sheet 51 has an insertion portion 511 that can be inserted into or pulled out of the lock body 10 to form the folding lock in a locked state or an unlocked state, wherein the second movable folding sheet 53 can rotate around the rotating axis of the assembly 60.

[0023] See also Figure 2 The lock body 10 has a locking structure 11 disposed in a sleeve assembly, the locking structure 11 includes a locking sleeve 12 and a lock core 13, one end of the locking sleeve 12 is connected to a rotating shaft 13a of the lock core 13 through an actuator 14, the lock core 13 has a lock hole 13b for a key 70 to be inserted, the lock hole 13b is arranged along a Z-axis direction, when the key 70 is rotated, the locking sleeve 12 can rotate back and forth along the X-axis direction simultaneously with the rotating shaft 13a.

[0024] The end of the locking sleeve 12 away from the lock core 13 is provided with an insertion portion 121, which is a groove provided on the side wall of the locking sleeve 12, and a locking block 511a is convexly provided on the wall of the insertion portion 511 of the first movable folding piece 51. When the first movable folding piece 51 is inserted, the insertion portion 121 allows the locking block 511a to be inserted into the locking sleeve 12 to form a locking member 511a. Figure 4 Unlocked state shown.

[0025] See also Figure 5 When the user turns the key 70 to rotate the shaft 13a forward, the locking sleeve 12 rotates forward at the same time, so that the locking block 511a enters and fits against the inner wall surface of the locking sleeve 12, and the first movable folding piece 51 cannot be pulled out to form a locked state.

[0026] In an embodiment of the utility model, the sleeve group includes an inner sleeve 21, a first outer sleeve 22 and a second outer sleeve 23. The locking sleeve 12 and the lock core 13 are arranged in the inner sleeve 21. The first outer sleeve 22 is sleeved on the outside of the inner sleeve 21 from the left side, and the second outer sleeve 23 is sleeved on the outside of the inner sleeve 21 from the right side, so that the sleeve group covers the locking sleeve 12 to improve the structural strength of the folding lock. The locking sleeve 12 limits the movement of the locking block 511a of the plug-in portion 511 of the first movable folding piece 51. Through the setting of the sleeve group, the locking sleeve 12 is limited to only rotate forward and backward, so that the first movable folding piece 51 will not be easily damaged or pulled out when it is in the locked state of the folding lock.

[0027] The inner sleeve 21 and the first outer sleeve 22 are both provided with openings 214, 221 corresponding to the insertion portion 121. The openings 214, 221 and the insertion portion 121 are arranged along the Y-axis direction. When the user wants to insert the first movable folding piece 51 into the lock body 10, the first movable folding piece 51 is inserted upward from the bottom of the lock body 10 into the openings 214, 221 and the insertion portion 121.

[0028] In addition, the side wall of the inner sleeve 21 is further provided with a slot 213, and the slot 213 is coaxially arranged with the openings 214 and 221. When the first movable folding piece 51 is inserted, a portion of the upper end of the plug-in portion 511 is restricted in the slot 213, and a portion of the lower end of the plug-in portion 511 is located in the openings 214 and 221. The slot 213 is mainly used to limit the movement of the plug-in portion 511, so that the first movable folding piece 51 can be more stably positioned in the inner sleeve 21, thereby improving the convenience of use.

[0029] Further, the assembly 60 has a fixing portion 61 and a connecting portion 62, the connecting portion 62 is extended downward from the fixing portion 61 along the Y-axis direction, and the second outer sleeve 23 and the inner sleeve 21 have corresponding insertion holes 231, 211, which are arranged along the Y-axis direction, for the fixing portion 61 of the assembly 60 to be inserted upward along the Y-axis direction into the insertion holes 231, 211 and fixed in the lock body 10. In the embodiment of the utility model, the fixing portion 61 is fixed to the outer shell of the lock core 13.

[0030] In addition, the inner sleeve 21 also has a fixing groove 212 coaxially arranged with the insertion hole 211. When the fixing portion 61 of the assembly 60 is inserted, a portion of the upper half of the fixing portion 61 is confined in the fixing groove 212, and a portion of the lower half of the fixing portion 61 is confined in the insertion hole 211. The fixing groove 212 and the clamping groove 213 are located at the left and right ends of the side wall surface of the inner sleeve 21, which are far away from each other.

[0031] When the user wants to pull the first movable folding piece 51 out of the lock body 10, in addition to turning the insertion portion 121 of the locking sleeve 12 to align with the openings 214 and 221 of the sleeve assembly, the user also needs to unfold the plurality of middle folding pieces 52 of the folding piece assembly to form a Figure 6 The state shown in the figure is to facilitate the first movable folding piece 51 to be pulled out from the lock body 10. This feature improves the overall strength of the folding lock and can more effectively prevent it from being damaged by malicious persons.

[0032] Further explanation, the folding lock of the utility model also has an outer shell 32 sleeved on the outside of the first outer sleeve 22, and an end cover 31 sleeved on the outside of the second outer sleeve 23. The outer shell 32 and the end cover 31 are both provided with an opening 321 and 311 for inserting the first movable folding piece 51 and the assembly 60 into the lock body 10, respectively. The outer shell 32 and the end cover 31 serve as a protective structure to prevent the sleeve assembly from being damaged. In addition, the end cover 31 has a key hole 31a for inserting the key 70 into the lock cylinder 13.

[0033] The utility model uses the locking sleeve 12 to limit the movement of the locking block 511a of the plug portion 511 of the first movable folding piece 51 to form a locked state or an unlocked state, and uses the sleeve assembly as a reinforcement structure to limit the locking sleeve 12 to only rotate forward and backward, thereby strengthening the overall structural strength, making the folding lock not easily damaged, and achieving a better anti-theft effect.
