Description

Technical Field

[0001] This utility model relates to the field of luggage lock technology, specifically to a swing-lock luggage lock. Background Technology

[0002] Zippered suitcases often feature a combination lock, used to lock the two zipper pins together. A prior art example of a combination lock for zippered suitcases can be found in prior patent 201520039304.9. This patent's combination lock includes a hook and a combination lock assembly, which comprises a combination wheel, a combination lock bushing, and a combination lock shaft. The combination lock shaft slidably passes through the combination lock bushing. When the combination is correct, the combination lock shaft has room to slide, allowing other components within the lock to move, thus unlocking the lock. Because the combination lock shaft and the combination lock bushing are in slidable contact, there is sliding friction between them. Overcoming this friction during the unlocking process requires effort.

[0003] The inventors then developed a zipper case combination lock disclosed in Chinese patent document CN207499638U, comprising a housing, a lock hook, a transmission assembly, and a combination lock assembly within the housing. The lock hook is rotatably connected to the housing. The housing also contains an anti-slip block that can swing relative to the housing. The transmission assembly has a stop latch. When the combination is incorrect, the anti-slip block is partially positioned within the stop latch, preventing the transmission assembly from moving and thus restricting the rotation of the lock hook, keeping it locked. When the combination is correct, the anti-slip block swings away from the stop latch, allowing the transmission assembly to move without restricting the lock hook's rotation, at which point the lock hook can rotate to unlock. This design eliminates the need for sliding between the dial wheel and axle to unlock the combination lock, thus reducing effort during the unlocking process.

[0004] The existing lock hook is rotatably connected to the housing, and the anti-rotation block is used to limit the rotation of the lock hook to keep the combination lock in the locked state. The anti-rotation block is provided with a connecting shaft and a actuating part, which extends radially outward from the side wall of the connecting shaft. The transmission rod is provided with a transmission protrusion for actuating the actuating part. During the sliding of the transmission rod, the transmission protrusion actuates the actuating part of the anti-rotation block to make the anti-rotation block rotate to not obstruct the rotation of the lock hook, so that the lock hook can rotate to unlock.

[0005] The actuating block of the anti-rotation swing block is located at the end of the connecting shaft. The rotating shaft of the anti-rotation swing block is horizontally placed. When rotating laterally, it relies on the transmission protrusion at the end of the transmission rod to laterally abut against the actuating part. Its stability needs to be further improved. Summary of the Invention

[0006] In view of the above-mentioned technical problems, the present invention provides a swing-type locking bag lock.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0009] The transmission assembly includes a pusher, a transmission seat, and a rigid anti-rotation swing block, which is hinged in the housing and can swing up and down; it also includes an elastic element that applies a spring force to the anti-rotation swing block so that the anti-rotation swing block swings upward to limit the rotation of the lock hook and achieve locking.

[0010] The pusher and the transmission seat are slidably mounted on the housing. When an external force pushes the pusher, it can overcome the force of the elastic element through the transmission seat and drive the anti-rotation swing block to swing downward, thereby releasing the anti-rotation swing block from restricting the rotation of the lock hook and realizing unlocking.

[0011] Specifically, the top of the anti-rotation block is provided with a guide slope, and a stop surface is provided at the adjacent position of the guide slope; the locking hook is provided with a guide arc surface and a locking surface. In the unlocked state, the guide arc surface and the guide slope surface cooperate to abut against each other. During the process of the locking hook rotating from the unlocked position to the locked position, the guide arc surface presses downward against the guide slope surface until the guide arc surface passes the guide slope surface, and then the locking surface cooperates to abut against the stop surface to restrict the rotation of the locking hook.

[0012] Specifically, the anti-rotation swing block is provided with a first rotating shaft and a second rotating shaft. The first rotating shaft is located at the end of the anti-rotation swing block and is hinged to the housing. The transmission seat is provided with an unlocking groove. The second rotating shaft is embedded in the unlocking groove so that when the transmission seat slides laterally, the anti-rotation swing block swings downward by abutting the second rotating shaft through the unlocking groove.

[0013] Specifically, the two second rotating shafts are symmetrically arranged on opposite sides of the anti-rotation swing block; the transmission seat is provided with two unlocking grooves corresponding to the two second rotating shafts.

[0014] Specifically, the transmission seat is provided with a receiving groove, the anti-rotation swing block is located in the receiving groove, and the unlocking inclined groove is located on the side wall of the receiving groove.

[0015] Specifically, the elastic element is an upward-facing spring arm that abuts against the anti-rotation swing block.

[0016] Specifically, the spring arm is integrally formed into the shell, and the spring arm is tilted upwards to abut the bottom of the anti-rotation swing block.

[0017] Specifically, a torsion spring is installed at the lock hook so that the lock hook automatically rotates to the unlocked position after the anti-rotation swing block releases its restriction on the lock hook.

[0018] The beneficial effects of this utility model are:

[0019] This utility model discloses a swing-type lock for bags. Compared with the prior art, the anti-rotation swing block is hinged to the housing and swings up and down. When the transmission seat slides, it pushes the anti-rotation swing block downward to swing and unlock, making the transmission more stable. Attached Figure Description

[0032] 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.

[0033] This embodiment describes a swing-lock bag lock, such as... Figures 1 to 6 As shown, it includes a long strip-shaped housing 1, inside which are provided a lock hook 2, a transmission component 3 and a password component 4. The housing has two lock holes 11, and the two lock hooks 2 are rotatably connected to the corresponding lock holes 11 inside the housing 1.

[0034] The transmission assembly 3 includes a pusher 31, a transmission seat 32, and a rigid anti-rotation swing block 33. The anti-rotation swing block 33 is horizontally placed and hinged inside the housing 1 and can swing up and down.

[0035] The bag lock also includes an elastic element 12 that applies a spring force to the anti-rotation swing block 33, so that the anti-rotation swing block 33 keeps swinging upward to limit the rotation of the lock hook 2 and achieve locking. Figure 5 The posture shown.

[0036] In this embodiment, the pusher 31 and the transmission seat 32 are slidably mounted on the housing 1 along the length of the housing 1. Only after the correct password is entered into the password component 4 can external force push the pusher 31. This external force pushes the pusher 31, which, via the transmission seat 32, overcomes the force of the elastic element 12 and causes the anti-rotation swing block 33 to swing downwards. This releases the anti-rotation swing block 33 from restricting the rotation of the lock hook 2, thus unlocking the lock. Figure 6 The lock hook 2 is shown in the figure. A torsion spring (not shown) is provided at the lock hook 2 so that after the anti-rotation swing block 33 releases its restriction on the lock hook 2, the lock hook 2 automatically rotates to the unlocked position.

[0037] Specifically, the top of the anti-rotation swing block 33 is provided with a guide slope 331, and a stop surface 332 is provided at the adjacent position of the guide slope 331; the lock hook 2 is provided with a guide arc surface 21 and a locking surface 22. In the unlocked state, the guide arc surface 21 cooperates with the guide slope 331 to abut against it. During the process of the lock hook 2 rotating from the unlocked posture to the locked posture, the guide arc surface 21 presses downward against the guide slope 331 until the guide arc surface 21 passes over the guide slope 331, and then the locking surface 22 cooperates to abut against the stop surface 332 to restrict the rotation of the lock hook 2.

[0038] Specifically, the anti-rotation swing block 33 is provided with a first rotating shaft 333 and a second rotating shaft 334. The first rotating shaft 333 is located at the end of the anti-rotation swing block 33 and is hinged to the housing 1. The transmission seat 32 is provided with an unlocking groove 321. The second rotating shaft 334 is embedded in the unlocking groove 321 so that when the transmission seat 32 slides laterally, the anti-rotation swing block 33 swings downward by abutting the second rotating shaft 334 through the unlocking groove 321.

[0039] Specifically, the two second rotating shafts 334 are symmetrically arranged on opposite sides of the anti-rotation swing block 33; the transmission seat 32 is provided with two unlocking grooves corresponding to the two second rotating shafts 334.

[0040] Specifically, the transmission seat 32 is provided with a receiving groove 322, the anti-rotation swing block 33 is located in the receiving groove 322, and the unlocking inclined groove 321 is located on the side wall of the receiving groove 322.

[0041] Specifically, the elastic element 12 is an upward-facing spring arm that abuts against the anti-rotation swing block 33. The spring arm is integrally formed into the housing 1, and the spring arm is tilted upward to abut against the bottom of the anti-rotation swing block 33. In practice, as a non-preferred option, a torsion spring can be provided at the first rotating shaft 333 to keep the anti-rotation swing block 33 in an upward swinging trend.
