Definitions

• the present disclosure relates to locks, in particular to a folding lock which is difficult to be damaged.
• Folding locks are favored by many cyclists because of their small size and portability.
• a disadvantage of folding locks is that their simple structure makes it easy for malicious individuals to use tools to damage the lock body, causing the folding lock to lose its anti-theft effect.
• the purpose of the present disclosure is to provide a folding lock, in particular a folding lock that is difficult to be damaged.
• a folding lock comprises a lock body having a locking structure disposed within a sleeve assembly.
• the locking structure comprises a locking sleeve and a lock core connected to each other.
• the lock core drives the locking sleeve to rotate back and forth along an X-axis direction.
• the locking sleeve has an insertion portion at one end remote from the lock core.
• the sleeve assembly comprises at least two sleeves each having an opening corresponding to the insertion portion, and the openings and the insertion portion are arranged along a Y-axis direction.
• the lock core has a keyhole arranged along a Z-axis direction; a folding plate assembly having a first movable folding plate, a second movable folding plate, and a plurality of intermediate folding plates connected to each other, wherein the first movable folding plate has an insertion protrusion inserted upward along the Y-axis direction into the insertion portion; and a connecting assembly having one end fixed inside the lock body and the other end connected to the second movable folding plate.
• the sleeve assembly includes an inner sleeve, a first outer sleeve, and a second outer sleeve.
• the locking structure is disposed within the inner sleeve, and the first outer sleeve and the second outer sleeve are simultaneously sleeved over the outer side of the inner sleeve.
• lock body further comprises an outer casing sleeved over the outer side of the first outer sleeve, and an end cap sleeved over the outer side of the second outer sleeve.
• both the inner sleeve and the first outer sleeve both have an opening corresponding to the insertion portion, and the inner sleeve has a side wall with a retaining groove that is coaxially arranged with the openings.
• the second outer sleeve and the inner sleeve have corresponding insertion holes arranged along the Y-axis direction for the connecting assembly to be inserted into the lock body.
• the inner sleeve further has a fixing groove coaxially arranged with the insertion hole for fixing the connecting assembly.
• the connecting assembly has a fixing portion and a connecting portion.
• the connecting portion extends downward along the Y-axis direction from the fixing portion.
• the fixing portion is inserted upward along the Y-axis direction through the insertion holes and fixed inside the lock body.
• both the outer casing and the end cap have an opening.
• the up-down direction is the insertion direction (i.e., the Y-axis direction) of the first movable folding plate 51 into the lock body 10
• the left-right direction is the insertion direction (i.e., the Z-axis direction) of the key 70
• the front-rear direction is the rotation direction (i.e., the X-axis direction) of the locking sleeve 12.
• a folding lock comprising a lock body 10, a folding plate assembly 50, and a connecting assembly 60.
• the folding plate assembly 50 comprises a first movable folding plate 51, a second movable folding plate 53, and a plurality of intermediate folding plates 52 connected to each other.
• the second movable folding plate 53 is connected to the lock body 10 through the connecting assembly 60.
• the plurality of intermediate folding plates 52 can be in a folded or unfolded state, and the first movable folding plate 51 has an insertion protrusion 511 that can be inserted into or pulled out of the lock body 10 to form a locked state or an unlocked state of the folding lock, wherein the second movable folding plate 53 can rotate around the axis of rotation of the connecting assembly 60.
• the lock body 10 has a locking structure 11 disposed within a sleeve assembly 20.
• 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 rotational shaft 13a of the lock core 13 via a connecting piece 14.
• the lock core 13 has a keyhole 13b for inserting a key 70, and the keyhole 13b is arranged along a Z-axis direction.
• the key 70 When the key 70 is rotated, it causes the locking sleeve 12 to rotate back and forth along the X-axis direction together with the rotational shaft 13a.
• the locking sleeve 12 has an insertion portion 121 at one end remote from the lock core 13.
• the insertion portion 121 is a groove formed in the side wall of the locking sleeve 12.
• the wall surface of the insertion protrusion 511 of the first movable folding plate 51 has a protruding lock block 511a.
• the insertion portion 121 allows the lock block 511a to be inserted into the locking sleeve 12, forming the unlocked state as shown in FIG. 4 .
• the sleeve assembly 20 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 disposed within the inner sleeve 21.
• the first outer sleeve 22 is sleeved over the outer side of the inner sleeve 21 from the left side
• the second outer sleeve 23 is sleeved over the outer side of the inner sleeve 21 from the right side, so that the sleeve assembly 20 covers the locking sleeve 12 to increase the structural strength of the folding lock.
• the locking sleeve 12 is restricted to rotate only back and forth, preventing the first movable folding plate 51 from being easily damaged and pulled out in the locked state of the folding lock.
• Both the inner sleeve 21 and the first outer sleeve 22 have openings 214 and 221 corresponding to the insertion portion 121.
• the openings 214 and 221, and the insertion portion 121, are arranged along the Y-axis direction.
• the side wall of the inner sleeve 21 has a retaining groove 213 coaxially arranged with the openings 214 and 221.
• the upper portion of the insertion protrusion 511 is restricted within the retaining groove 213, and the lower portion of the insertion protrusion 511 is positioned within the openings 214 and 221.
• the main purpose of the retaining groove 213 is to limit the movement of the insertion protrusion 511, allowing the first movable folding plate 51 to be more stably positioned within the inner sleeve 21 to improve usability.
• the connecting assembly 60 has a fixing portion 61 and a connecting portion 62, and the connecting portion 62 extends downward along the Y-axis direction from the fixing portion 61.
• the second outer sleeve 23 and the inner sleeve 21 have corresponding insertion holes 231 and 211 arranged along the Y-axis direction, to allow the fixing portion 61 of the connecting assembly 60 to be inserted upward along the Y-axis direction through the insertion holes 231 and 211 and fixed inside the lock body 10.
• the fixing portion 61 is fixed to the outer casing of the lock core 13.
• the inner sleeve 21 also has a fixing groove 212 coaxially arranged with the insertion hole 211.
• the fixing groove 212 and the retaining groove 213 are positioned on the extreme left and right sides of the side wall of the inner sleeve 21.
• the folding lock of the present disclosure further has an outer casing 32 sleeved over the outer side of the first outer sleeve 22, and an end cap 31 sleeved over the outer side of the second outer sleeve 23.
• the outer casing 32 and the end cap 31 both have openings 321 and 311, respectively, for the first movable folding plate 51 and the connecting assembly 60 to be inserted into the lock body 10.
• the outer casing 32 and the end cap 31 serve as protective structures to prevent the sleeve assembly 20 from being damaged.
• the end cap 31 has a keyhole 31a for inserting the key 70 into the lock core 13.
• the locking or unlocking state is achieved by restricting the movement of the lock block 511a of the insertion protrusion 511 of the first movable folding plate 51 with the locking sleeve 12.
• the sleeve assembly 20 serves as a reinforcing structure by limiting the locking sleeve 12 to rotate only back and forth, which increases the overall structural strength, makes the folding lock difficult to be damaged, and achieves a better anti-theft effect.
