[0002] A bag lock is a type of lock accessory installed on bags. Its function is to lock closed bags to prevent them from being accidentally opened or stolen.

[0003] The bag has a frame on both sides of the opening. The outer side of the frame is rounded and raised. The frame can increase the strength of the edge of the bag opening and facilitate the installation of the bag lock. The bag lock currently used includes a first mounting base, a second mounting base, and a lock plate. One end of the lock plate is hinged to the first mounting base, and the other end of the lock plate is the locking end. The second mounting base is provided with a locking structure for locking the locking end of the lock plate.

[0004] The existing technology has a hinged structure at the end of the lock plate that is not compact enough. It relies on the lock plate's hook to be inserted into the lock hole for locking. In the event of a collision or heavy drop of the bag, the lock hook is prone to breakage, which affects safety. Summary of the Invention

[0005] In view of the above-mentioned technical problems, the present invention provides a lifting-type luggage lock.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A lifting-type luggage lock is provided, including a lock housing, a locking mechanism, an unlocking component, a lock plate, and a swing block. The lower end of the swing block is hinged to the lock housing, and the upper end of the swing block is hinged to the middle of the lock plate. A lock hook is provided at the front end of the lock plate.

[0008] When unlocking, the entire lock plate swings forward around the swing block as the pivot to lift relative to the lock housing; when locking, the entire lock plate swings backward around the swing block as the pivot and lies against the lock housing.

[0009] The locking mechanism holds the lock plate in place; after the correct command is input into the locking mechanism, external force can be used to unlock the lock plate.

[0010] Specifically, the top of the lock case is provided with a positioning groove, and the lock plate is provided with a positioning protrusion. When locked, the positioning protrusion is embedded in the positioning groove.

[0011] Specifically, the swing block includes a first rod and a second rod installed on opposite sides of the lock plate; and / or: the upper end surface of the swing block is provided with a rounded corner and a flat part, which guides the lock plate to move when it swings, and the flat part abuts against the lock plate when it is unlocked, so that the lock plate posture is the same as the posture when it is locked.

[0012] Specifically, the lock housing is provided with a stop groove to limit the swing amplitude of the lock plate, and the swing block abuts against the groove wall in the unlocked state; and / or: the hinge shaft between the swing block and the lock housing is provided with a spring so that the lock plate automatically rises after the restriction is released.

[0013] Specifically, the lock plate is shaped like a square, with a clearance groove in the middle.

[0014] Specifically, the locking mechanism includes a locking element, a limiting block, a key assembly, and a password assembly. In the locked state: the locking element is locked onto the lock plate, and the limiting block is in the locked position, restricting the movement of the locking element; when the correct key is inserted into the key assembly or the correct password is entered into the password assembly as the correct instruction, the limiting block can be moved to the unlock position to release the restriction on the locking element. External force operates the unlocking element to move the locking element and release the restriction on the lock plate.

[0015] Specifically, the locking component is equipped with a locking pin, and the lock plate is equipped with a lock hole. In the locked state, the locking pin is inserted into the lock hole, and in the unlocked state, the locking pin is disengaged from the lock hole.

[0016] Specifically, the locking element and the limiting block are slidably mounted on the lock housing, and their sliding directions are perpendicular to each other; the locking element is provided with a first stop post, and the limiting block is provided with a second stop post. In the locked state, the first stop post is aligned with the second stop post, and in the unlocked state, the first stop post is offset from the second stop post.

[0017] Specifically, the top of the lock housing is integrally formed with an assembly platform, which is embedded in the clearance groove when locked. The unlocking component is a button set on the assembly platform. The button has a push part, and the locking component has an unlocking slope that matches the push part. When the button is pressed down with external force, the push part can slide along the unlocking slope, thereby driving the locking component to slide in a perpendicular direction to unlock.

[0018] Specifically, the key assembly includes a lock cylinder rotatably mounted in the button, with a lever at the bottom of the lock cylinder. Rotating the lock cylinder can drive the lever to move the limit block to the unlock position; and / or: the combination assembly includes multiple combination wheels, multiple code-changing wheels, a knob, and a linkage plate.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] This embodiment provides a lifting-type luggage lock, such as... Figures 1 to 7As shown, it includes a lock housing 1, a locking mechanism 2, an unlocking component 3, a lock plate 4, and a swing block 5. The lower end of the swing block 5 is hinged to the lock housing 1 via a pivot, and the upper end of the swing block 5 is hinged to the middle of the lock plate 4 via a pivot. The front end of the lock plate 4 is provided with a lock hook 41 for hooking the opening and closing side of the bag.

[0036] When unlocking, the lock plate 4 swings forward around the swing block 5 as a pivot, thus raising it relative to the lock case 1 (e.g., Figure 2 (as shown); When locked, the lock plate 4 swings backward around the swing block 5 as the pivot and rests downward against the lock housing 1 (as shown). Figure 1 (As shown). The locking mechanism 2 holds the locking plate 4 in place; after the correct command is input into the locking mechanism 2, external force can be used to operate the unlocking component 3 to release the restriction on the locking plate 4.

[0037] Specifically, the top of the lock housing 1 is recessed and formed with a positioning groove 11, and the lock plate 4 is provided with a positioning protrusion 42. When locked, the positioning protrusion 42 is embedded in the positioning groove 11, so that the lock plate 4 and the lock housing 1 fit more tightly when locked, and are not easy to loosen laterally.

[0038] Specifically, the swing block 5 includes a first rod 51 and a second rod 52 installed on opposite sides of the lock plate 4, resulting in a more stable symmetrical structure. The upper surface of the swing block 5 is provided with a rounded corner 53 and a flat section 54. When the lock plate 4 swings, it abuts against the rounded corner 53 for guidance, making the switching between the two positions of the lock plate 4 smoother. In the unlocked state, the flat section 54 abuts against the lock plate 4, thus making the lock plate 4's posture the same as in the locked state. It can be seen in the figure that in both states, the lock plate 4 is basically parallel to the top of the lock case 1.

[0039] Specifically, the lock housing 1 is provided with a stop groove 12 to limit the swing amplitude of the lock plate 4. In the unlocked state, the swing block 5 abuts against the groove wall of the stop groove 12, and the lock block rotates approximately 90° from the locked state to the unlocked state. The hinge shaft between the swing block 5 and the lock housing 1 is provided with a spring so that after the locking mechanism 2 releases the restriction on the lock plate 4, the lock plate 4 automatically rises to unlock.

[0040] Specifically, the lock plate 4 is U-shaped, with a clearance groove 43 in the middle.

[0041] Specifically, the locking mechanism 2 includes a locking member 21, a limiting block 23, a key assembly 25, and a combination lock assembly 26. In the locked state: the locking member 21 engages with the lock plate 4, and the limiting block 23 is in the locked position, restricting the movement of the locking member 21; specifically, the locking member 21 is provided with a locking pin 211, and the rear end of the lock plate 4 is provided with a lock hole 44. In the locked state, the locking pin 211 is inserted into the lock hole 44. When the correct key is inserted into the key assembly 25 or the correct combination lock is entered into the combination lock assembly 26 as the correct instruction, the limiting block 23 can be moved to the unlock position to release the restriction on the locking member 21. An external force operates the unlocking member 3 to move the locking member 21 to release the restriction on the lock plate 4, that is, the locking pin 211 disengages from the lock hole 44.

[0042] Specifically, the locking member 21 and the limiting block 23 are slidably installed on the lock housing 1, and their sliding directions are perpendicular to each other; the locking member 21 is provided with a first stop post 22, and the limiting block 23 is provided with a second stop post 24. In the locked state, the first stop post 22 is aligned with the second stop post 24, and in the unlocked state, the first stop post 22 is offset from the second stop post 24.

[0043] Specifically, the top of the lock housing 1 is integrally formed with an assembly platform 13, which is embedded in the clearance groove 43 when locked. The unlocking component 3 is a button set on the assembly platform 13. The button is provided with a cylindrical pushing part 31, and the locking component 21 is provided with an unlocking slope 212 adapted to the pushing part 31. When the button is pressed down with external force, the pushing part 31 can slide along the unlocking slope 212, thereby driving the locking component 21 to slide and unlock in a perpendicular direction.

[0044] Specifically, the key assembly 25 includes a lock core 251 rotatably mounted in the button. A lever 252 is located at the bottom of the lock core 251. After inserting the correct key, the lock core 251 rotates, causing the lever 252 to move the limit block 23 to the unlock position. The combination lock assembly 26 includes multiple combination wheels 261, multiple dialing wheels 262, a knob 263, and a linkage plate 264. The combination wheels 261 and dialing wheels 262 are rotatably mounted on the lock housing 1. The knob 263 is rotatably mounted on the lock housing 1 and connected to the linkage plate 264. The linkage plate 264 corresponds to each dialing wheel 262. A recessed-convex interlocking structure is provided between the outer side of the dialing wheel 262 and the linkage plate 264. After entering the correct combination, the linkage plate 264 moves laterally, thereby rotating the knob 263. The knob 263 then moves the limit block 23 to the unlock position.

[0045] In practice, reset springs are provided at the linkage plate 264, the unlocking component 3, the locking component 21, and the limiting component, so that they are elastically in the corresponding positions.
