Description
Technical Field
[0001] This utility model relates to the field of locking devices, and in particular to a bag lock. Background Technology
[0002] As people's living standards continue to improve, the frequency of travel is also gradually increasing. When traveling, people typically carry bags to carry their luggage. Bags are used to store clothing, personal care products, and souvenirs needed for the trip. To prevent theft, most bags on the market are equipped with locks. In existing locks, the rotating cover and locking ring are separate components. During locking, the locking ring needs to be engaged with the latch before the rotating cover is flipped and secured to the lock, making the locking ring and latch locked together. This is rather cumbersome to use. Summary of the Invention
[0003] In order to address the technical deficiencies mentioned in the background art, the purpose of this utility model is to provide a bag lock.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A bag lock includes a hook base, a lock base, and a lock cover; the hook base is provided with a latch, and the lock base is provided with a lock cylinder; the lock cover includes a press cover, a latch at one end of the press cover, and a fixing member below the press cover; the latch is engaged with the latch; one end of the fixing member near the latch is hinged to the lock base, and the other end of the fixing member is hinged to the other end of the press cover away from the latch; the lock cylinder is used to fix the fixing member.
[0006] By adopting the above technical solution, the press cover, locking mechanism, and fixing component are integrated into a single unit, making processing faster and assembly more convenient. The press cover and fixing component are hinged together. When locking, simply pressing down on the press cover simultaneously engages the locking mechanism in the hook and accurately aligns the fixing component with the lock cylinder, simplifying operation and increasing locking efficiency. Moreover, when opening is required, first unlocking the fixing component from the lock cylinder, then simply lifting the press cover easily separates the locking mechanism from the hook, opening both the press cover and the fixing component. This saves time and effort, ensures stable and reliable operation, facilitates operation, and reduces production costs.
[0007] Furthermore, the end of the lock seat connected to the fixing member is bent and has a connecting part. The fixing member has a first connecting shaft, which passes through the connecting part to form a hinged connection. The structure is simple, compact, and cost-effective.
[0008] Furthermore, a first torsion spring is sleeved on the first connecting shaft. One end of the first torsion spring abuts against the lower surface of the fixing member, and the other end of the first torsion spring abuts against the lower surface of the pressing cover. The first torsion spring can provide a force to push open the latch and the hook, making it easier to open the lock.
[0009] Furthermore, a second connecting shaft is provided below the other end of the fixing member. The second connecting shaft passes through the other end of the pressing cover and the other end of the fixing member in sequence to make the fixing member and the pressing cover hingedly connected. The structure is simple and easy to assemble.
[0010] Furthermore, the first connecting shaft, the second connecting shaft, and the locking element are offset in the height direction, with the height of the first connecting shaft being higher than the height of the second connecting shaft and the locking element. This can improve the stability of the locking, make the locking more secure, and prevent disengagement.
[0011] Furthermore, a second torsion spring is fitted onto the second connecting shaft. One end of the second torsion spring abuts against the lower surface of the fixing member, and the other end abuts against the upper surface of the lock seat. The second torsion spring provides an opening force to the fixing member and the pressing cover, allowing for faster and more convenient separation of the lock cylinder from the fixing member.
[0012] Furthermore, the fixing member has a recessed groove for the lock cylinder position, through which the lock cylinder passes. The adjacent sides of the recessed groove are spaced at different distances from the lock cylinder, facilitating rotation of the lock cylinder to open or lock the fixing member. The upper end of the lock cylinder has a keyhole, and one side of the lock cylinder protrudes a locking block for pressing against the upper surface of the fixing member, resulting in a more stable engagement. The pressing block has a keyhole corresponding to the recessed groove position. One end of the key passes through the keyhole and is inserted into the lock cylinder to drive the locking block to lock or move away from the fixing member, simplifying operation and making it more convenient to use.
[0013] Furthermore, the upper surface of the press cover is provided with a recessed mounting groove, which is used to attach labels, thus enhancing compatibility.
[0014] In summary, the beneficial effects of this utility model are as follows:
[0015] The press cover, latch, and fixing component in this invention are integrated into a single unit, making processing faster and assembly more convenient. The press cover and fixing component are hinged together. When locking, simply pressing down on the press cover simultaneously engages the latch in the hook and accurately aligns the fixing component with the lock cylinder, resulting in simple operation and higher locking efficiency. Furthermore, when opening is required, first unlocking the fixing component from the lock cylinder, then simply lifting the press cover easily separates the latch from the hook, opening both the press cover and the fixing component. This saves time and effort, ensures stable and reliable operation, is convenient to operate, and has low production costs. Attached Figure Description

[0027] A type of bag lock 1, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a hook base 2, a lock base 3, and a lock cover. The hook base 2 is provided with a latch 21, and the lock base 3 is provided with a lock cylinder 31. The lock cover includes a pressing cover 41, a latch 42 located at one end of the pressing cover 41, and a fixing member 43 located below the pressing cover 41. The latch 42 is engaged with the latch 21. The end of the fixing member 43 near the latch 42 is hinged to the lock base 3, and the other end of the fixing member 43 is hinged to the end of the pressing cover 41 away from the latch 42. The lock cylinder 31 is used to fix the fixing member 43.
[0028] The press cover 41, latch 42, and fixing member 43 are integrated into a single unit, making processing faster and assembly more convenient. The press cover 41 and fixing member 43 are hinged together. When locking, simply pressing down on the press cover 41 simultaneously engages the latch 42 within the hook 21 and accurately aligns the fixing member 43 with the lock cylinder 31, simplifying operation and increasing locking efficiency. Furthermore, when opening, first unlocking the fixing member 43 from the lock cylinder 31, then simply lifting the press cover 41 easily separates the latch 42 from the hook 21, opening both the press cover 41 and the fixing member 43. This saves time and effort, ensures stable and reliable operation, and reduces production costs. The other ends of the press cover 41 and fixing member 43 are spaced vertically for easy opening.
[0029] In some embodiments, please refer to Figure 3 , Figure 5 The lock base 3 is bent at one end and has a connecting part 32 at the other end connected to the fixing member 43. The fixing member 43 has a first connecting shaft 44, which passes through the connecting part 32 for hinged connection. The structure is simple, compact and cost-effective.
[0030] Preferably, a first torsion spring 45 is sleeved on the first connecting shaft 44. One end of the first torsion spring 45 abuts against the lower surface of the fixing member 43, and the other end of the first torsion spring 45 abuts against the lower surface of the pressing cover 41. The first torsion spring 45 can provide a force to push open the locking member 42 and the hook 21, making it easier to open the latch. When in the locked state, the first torsion spring 45 is in an elastically compressed state, and only a small force is needed to separate the hook 21 from the locking member 42. The locking member 42 is designed as a rod-shaped structure, which facilitates locking into the hook groove of the hook 21.
[0031] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 5 A second connecting shaft 46 is provided below the other end of the fixing member 43. The second connecting shaft 46 passes through the other end of the pressing cover 41 and the other end of the fixing member 43 in sequence so that the fixing member 43 and the pressing cover 41 are hinged together. The structure is simple and easy to assemble.
[0032] Please refer to Figure 3 The first connecting shaft 44, the second connecting shaft 46, and the locking piece 42 are offset in the height direction. The height of the first connecting shaft 44 is higher than the height of the second connecting shaft 46 and the locking piece 42, which can improve the stability of locking, make locking more secure, and prevent disengagement.
[0033] Preferably, a second torsion spring 47 is fitted onto the second connecting shaft 46. One end of the second torsion spring 47 abuts against the lower surface of the fixing member 43, and the other end of the second torsion spring 47 abuts against the upper surface of the lock seat 3. The second torsion spring 47 can provide an opening force to the fixing member 43 and the pressing cover 41, allowing for faster and more convenient separation of the lock cylinder 31 from the fixing member 43.
[0034] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 5The fixing member 43 has a recessed groove 431 for the lock cylinder 31. The lock cylinder 31 passes through the recessed groove 431. The distances between the two adjacent sides of the recessed groove 431 and the lock cylinder 31 are different, which facilitates rotating the lock cylinder 31 to open or lock the fixing member 43. The upper end of the lock cylinder 31 has a lock hole, and one side of the lock cylinder 31 has a protruding locking block for pressing against the upper surface of the fixing member 43, which makes the locking more stable. The pressing block 33 has an insertion hole 411 for inserting the key 5 at the position corresponding to the recessed groove 431. One end of the key 5 passes through the insertion hole 411 and the lock hole and is inserted into the lock cylinder 31 to drive the locking block to lock the fixing member 43 or move away from the fixing member 43. The operation is simple and more convenient.
[0035] In some embodiments, please refer to Figure 1 The upper surface of the press cover 41 is provided with a recessed mounting groove 412, which is used for attaching labels and has better compatibility. Specifically, two mounting grooves 412 are provided on both sides of the socket 411.
[0036] The lock base 3 is fixed to the open side of the bag, and the hook base 2 is located on the other open side. In the unlocked state, the press cover 41, the fixing member 43, and the lock base 3 are hinged together, with the locking member 42 located on the inner side of the end of the press cover 41. The press cover 41, fixing member 43, and lock base 3 are arranged in a Z-shape. When locking is required, pressing down the press cover 41 simultaneously engages the locking member 42 in the hook 21, aligns the recess 431 of the fixing member 43 with the lock cylinder 31, inserts the key 5, and rotates the lock cylinder 31, causing the press block 33 on the lock cylinder 31 to abut against the upper surface of the fixing member 43, thus fixing the other end of the fixing member 43 and the press cover 41 to the lock base 3. To unlock, the key 5 is reversed to open the press block 33 and the fixing member 43. Pulling up the other end of the fixing member 43 causes the press cover 41 to rotate, bringing out the locking member 42 and separating it from the hook 21, making unlocking easier.
