Description

Technical Field

[0001] This utility model relates to a lock assembly, and more particularly to a rotary lock. Background Technology

[0002] Luggage locks are locks specifically designed for luggage, backpacks, handbags, and other luggage products. The lock consists of two parts: a male buckle and a female buckle. The male buckle and female buckle are installed on the main body and the lid of the luggage, respectively. When the male buckle and female buckle are installed together, the lid of the luggage can be tightly closed on the main body.

[0003] Traditional luggage locks typically use magnetic or snap-on mechanisms. For magnetic locks, the male and female snaps don't always fit securely, allowing the lid to open accidentally and items to be lost. Furthermore, the magnetic mechanism can fail over time, preventing the snaps from locking properly. Snap-on locks, on the other hand, have a complex structure, making assembly difficult and reducing production efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a rotary lock to address the shortcomings of existing technologies.

[0005] A rotary lock includes a lock sleeve and a lock cylinder. The lock cylinder is freely detachable from the lock sleeve. The lock sleeve has a mating hole and a guide hole. The guide hole is located on the outer periphery of the mating hole and communicates with the mating hole in the horizontal direction. The lock cylinder includes a handle, a first adjusting seat, a second adjusting seat, a base, a bottom plate, a limiting rod, and a spring. The handle, the first adjusting seat, the second adjusting seat, the base, and the bottom plate are sequentially distributed along the installation direction of the lock sleeve and the lock cylinder. The first adjusting seat can be adjusted synchronously with the handle. The limiting rod passes through the second adjusting seat and is installed in the first adjusting seat. On the seat, the two ends of the spring respectively abut against the limiting rod and the second adjusting seat, so that the first adjusting seat and the second adjusting seat are tightly fitted. The first adjusting seat has several locking protrusions on the side near the second adjusting seat, and the second adjusting seat has several locking grooves on the side near the first adjusting seat. The shape of the locking grooves corresponds to the locking protrusions. During the rotation of the handle, the locking protrusions on the first adjusting seat retract from the initial locking groove and lock into another locking groove. When the lock sleeve and the lock cylinder are installed together, the handle passes through the guide hole of the lock sleeve and rotates, so that the handle and the guide hole are misaligned.

[0006] In one embodiment, the first adjusting seat has a stop block on the side near the second adjusting seat, and a locking protrusion is connected to the stop block. The locking protrusion is connected to the side of the stop block near the second adjusting seat, and the locking protrusions are evenly spaced around the axis of the first adjusting seat.

[0007] In one embodiment, the side of the locking protrusion facing away from the stop block is planar, thus forming a bottom plane. The cross-sectional outline of the locking protrusion gradually increases in size from the bottom plane toward the stop block, thereby forming a sloping guide surface on the outer periphery of the locking protrusion.

[0008] In one embodiment, the locking sleeve includes a main body, a washer, and a first locking screw that fixes the washer to the main body. The main body includes a limiting plate and a connecting ring connected to the limiting plate. During assembly, the washer fits against the connecting ring, and the washer and the limiting plate are spaced apart and arranged opposite each other. The first locking screw passes through the washer and is installed on the connecting ring.

[0009] In one embodiment, the mating hole and the guide hole both penetrate the limiting plate, the connecting ring and the gasket, and there are two guide holes, which are arranged opposite to each other.

[0010] In one embodiment, the lock cylinder further includes a second locking screw, a third locking screw, and a fourth locking screw. The handle is fixed to the first adjusting seat by the second locking screw, the second adjusting seat is fixed to the base by the third locking screw, and the base is fixed to the bottom plate by the fourth locking screw.

[0011] In one embodiment, the base includes a main body and a plurality of docking posts connected to the main body. The docking posts are disposed on the side of the main body near the bottom plate. The fourth locking screw passes through the bottom plate and is fixed to the docking posts of the base. The bottom plate and the main body are arranged opposite to each other and form a gap.

[0012] In one embodiment, the first adjusting seat is further provided with a positioning groove, which passes through the inner side of the locking protrusion and extends into the middle of the stop block. The first adjusting seat is further provided with a screw hole with internal threads at the bottom of the positioning groove. The limiting rod includes a limiting block, a connecting rod and a connecting head connected in sequence. The connecting head is provided with external threads corresponding to the screw hole. The connecting head of the connecting rod is installed on the screw hole of the first adjusting seat by threads.

[0013] In one embodiment, the second adjusting seat is further provided with a through hole, which penetrates the second adjusting seat along the main axis direction. In addition, the second adjusting seat has an adjusting groove on the side facing away from the first adjusting seat. The through hole passes through the adjusting groove, and the connector of the connecting rod passes through the adjusting groove and the through hole. The outer diameter of the connecting rod is smaller than the outer diameter of the limiting block. The two ends of the spring elastically abut against the bottom of the limiting block and the adjusting groove, respectively, and the spring compresses the limiting block of the connecting rod.

[0014] In one embodiment, the card slots are evenly spaced around the through holes.

[0015] The beneficial effects of this rotary lock are as follows: By setting a handle, a first adjusting seat, and a second adjusting seat on the lock cylinder, the first adjusting seat can be adjusted synchronously with the handle. Furthermore, a guide hole is set on the lock sleeve. When the lock sleeve and lock cylinder are installed together, the handle passes through the guide hole of the lock sleeve and rotates, so that the handle and the guide hole are misaligned, thereby fixing the lock sleeve and lock cylinder together. During the rotation of the handle, the locking protrusion on the first adjusting seat exits from the initial locking groove and locks into another locking groove, effectively preventing the handle from rotating arbitrarily. This utility model can achieve a stable installation between the lock sleeve and the lock cylinder. Moreover, the overall structure is simple, effectively reducing product costs and improving production efficiency. Attached Figure Description

[0028] Please see Figures 1 to 8 This utility model provides a rotating lock, including a lock sleeve 10 and a lock cylinder 20. The lock cylinder 20 can be freely installed and removed from the lock sleeve 10. During assembly, the lock sleeve 10 is installed on the bag cover, and the lock cylinder 20 is installed on the bag body. Through the cooperation of the lock cylinder 20 and the lock sleeve 10, the bag cover is closed on the bag body.

[0029] The locking sleeve 10 includes a main body 11, a washer 12, and a first locking screw 13 that fixes the washer 12 to the main body 11. The main body 11 includes a limiting plate 111 and a connecting ring 112 connected to the limiting plate 111. During assembly, the washer 12 and the connecting ring 112 are in contact, with a certain distance between the washer 12 and the limiting plate 111 and they are arranged opposite each other. The first locking screw 13 passes through the washer 12 and is installed on the connecting ring 112. When the locking sleeve 10 is installed on the bag cover, the bag cover has a first assembly hole corresponding to the shape of the connecting ring 112.

[0031] The lock cylinder 20 includes a handle 21, a first adjusting seat 22, a second locking screw 23, a second adjusting seat 24, a base 25, a third locking screw 26, a base plate 27, a fourth locking screw 28, a limiting rod 29, and a spring 210. The handle 21, the first adjusting seat 22, the second adjusting seat 24, the base 25, and the base plate 27 are distributed sequentially along the installation direction of the lock sleeve 10 and the lock cylinder 20.

[0032] The handle 21 is fixed to the first adjusting seat 22 by a second locking screw 23. The second adjusting seat 24 is fixed to the base 25 by a third locking screw 26. The base 25 is fixed to the base plate 27 by a fourth locking screw 28. The limiting rod 29 passes through the second adjusting seat 24 and is mounted on the first adjusting seat 22. The two ends of the spring 210 abut against the limiting rod 29 and the second adjusting seat 24 respectively, keeping the first adjusting seat 22 and the second adjusting seat 24 in a tight fit. The handle 21 can be rotated for adjustment, and during the rotation of the handle 21, the first adjusting seat 22 is adjusted synchronously.

[0033] The first adjusting seat 22 has a stop block 221 and a plurality of locking protrusions 222 connected to the stop block 221 on the side of the second adjusting seat 24. The locking protrusions 222 are connected to the side of the stop block 221 near the second adjusting seat 24. The locking protrusions 222 are evenly spaced around the axis of the first adjusting seat 22. The side of the locking protrusions 222 facing away from the stop block 221 is flat, thus forming a bottom plane 223. The cross-sectional outline of the locking protrusions 222 gradually increases in size from the bottom plane 223 toward the stop block 221, thereby forming a sloping guide surface 224 on the outer periphery of the locking protrusions 222. In this embodiment, the number of locking protrusions 222 is four.

[0034] In addition, the first adjusting seat 22 is also provided with a positioning groove 225, which passes through the inner side of the locking protrusion 222 and extends into the middle of the stop block 221. The first adjusting seat 22 is further provided with a screw hole 226 with internal thread at the bottom of the positioning groove 225.

[0035] The second adjusting seat 24 is provided with a plurality of slots 241 on the side of the first adjusting seat 22. The shape of the slots 241 corresponds to the positioning protrusions 222. The second adjusting seat 24 is also provided with a through hole 242. The through hole 242 passes through the second adjusting seat 24 along the main axis direction. The slots 241 are evenly spaced around the through hole 242. In addition, the second adjusting seat 24 is provided with an adjusting groove 243 on the side of the second adjusting seat 24 facing away from the first adjusting seat 22. The through hole 242 passes through the adjusting groove 243.

[0036] The limiting rod 29 includes a limiting block 291, a connecting rod 292 and a connecting head 293 connected in sequence. The outer diameter of the connecting rod 292 is smaller than the outer diameter of the limiting block 291. The connecting head 293 is provided with an external thread, which corresponds to the screw hole 226.

[0037] The base 25 includes a main body 251 and a plurality of docking posts 252 connected to the main body 251. The docking posts 252 are disposed on the side of the main body 251 near the bottom plate 27.

[0038] During assembly, the second locking screw 23 passes through the first adjusting seat 22 and is fixed to the handle 21; the third locking screw 26 passes through the base 25 and is fixed to the second adjusting seat 24; and the fourth locking screw 28 passes through the base plate 27 and is fixed to the mating post 252 of the base 25. The base plate 27 and the main body 251 are positioned opposite each other and form a gap. The spring 210 is sleeved around the connecting rod 292. The connector 293 of the connecting rod 292 passes through the adjusting groove 243 and the through hole 242 and is threaded onto the screw hole 226 of the first adjusting seat 22. The two ends of the spring 210 elastically abut against the limiting block 291 and the bottom of the adjusting groove 243, respectively. The spring 210 presses against the limiting block 291 of the connecting rod 292, causing the connecting rod 292 to press against the first adjusting seat 22, thereby ensuring a tight fit between the first adjusting seat 22 and the second adjusting seat 24. By rotating the first adjusting seat 22 with handle 21, when the locking protrusion 222 is aligned with the slot 241, the spring 210 presses the connecting rod 292 and the first adjusting seat 22, causing the locking protrusion 222 to lock into the slot 241. During further rotation, the locking protrusion 222 exits from the slot 241 through the inclined guide surface 224.

[0039] When the lock cylinder 20 is installed with the bag body, the bag body is provided with a second assembly hole for installation with the lock cylinder 20. The docking post 252 of the base 25 passes through the second assembly hole, and the main body 251 and the bottom plate 27 of the base 25 are respectively locked at the openings on both sides of the second assembly hole.

[0040] When the lock sleeve 10 and the lock cylinder 20 are installed together, the handle 21 of the lock cylinder 20 passes through the guide hole 15 of the lock sleeve 10 and extends out of the lock sleeve 10. The first adjusting seat 22 and the second adjusting seat 24 extend into the mating hole 14. When the handle 21 is rotated, the handle 21 is misaligned with the guide hole 15. The lock sleeve 10 limits the handle 21 in the unlocking direction. The locking protrusion 222 exits from the initial locking groove 241 and locks into another locking groove 241.

[0041] The beneficial effects of this rotary lock are as follows: By setting a handle 21, a first adjusting seat 22, and a second adjusting seat 24 on the lock cylinder 20, the first adjusting seat 22 can be adjusted synchronously with the handle 21. Furthermore, a guide hole 15 is set on the lock sleeve 10. When the lock sleeve 10 and the lock cylinder 20 are installed together, the handle 21 passes through the guide hole 15 of the lock sleeve 10 and rotates, so that the handle 21 and the guide hole 15 are misaligned, thereby fixing the lock sleeve 10 and the lock cylinder 20 together. During the rotation of the handle 21, the locking protrusion 222 on the first adjusting seat 22 exits from the initial locking groove 241 and locks into another locking groove 241, effectively preventing the handle 21 from rotating arbitrarily. This utility model can achieve a stable installation between the lock sleeve 10 and the lock cylinder 20. Moreover, the overall structure is simple, effectively reducing product costs and improving production efficiency.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
