Description

Technical Field

[0001] This utility model relates to the field of locking mechanism technology, and in particular to a double-opening lock mechanism. Background Technology

[0002] A roof box is a storage device installed on the roof of a car, effectively expanding the vehicle's luggage storage space. With the improvement of people's living standards and the diversification of travel needs, users are increasingly demanding higher levels of safety, convenience, and stability from roof boxes. During use, roof boxes typically require the use of locks to securely fasten them to the roof to ensure stability and reliability while driving, preventing them from loosening or falling off.

[0003] However, most of the locks used in existing roof boxes adopt a one-way locking structure, which usually relies on only one side of the slider or latch for fixation. The number of locking points is limited, and the force distribution is uneven. Especially when the vehicle is moving, the road is bumpy, or the items are vibrating, there is a risk of loosening, displacement, or even falling off. In actual use, locking and unlocking often need to be operated separately on the left and right sides, which is cumbersome and inefficient, and not conducive to fixing large items or items that need to be frequently disassembled. In addition, some existing structures lack effective linkage and limit mechanisms, and the movement of the slider is uncontrolled, which can easily lead to excessive displacement or poor engagement. This not only reduces the locking accuracy but also accelerates the wear of components, affecting the overall stability and service life. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a double-opening lock mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-opening lock mechanism includes a lock body and a connecting buckle. An insertion frame is fixedly installed on one side of the top of the lock body. The lower end of the connecting buckle is slidably inserted into the insertion frame. A sliding cavity is provided inside the lock body. A left slider is slidably installed on the left side of the sliding cavity, and a right slider is slidably installed on the right side. A locking component is provided between the left slider and the connecting buckle. A driving component installed inside the lock body is provided below the left side of the left slider. The driving component is used to move the left slider horizontally. A transmission component is provided between the left slider and the right slider to realize the reverse linkage between the left slider and the right slider.

[0007] Preferably, the locking assembly includes a locking groove formed at the lower end of the connecting buckle, and a locking head fixedly installed above the right end of the left slider, wherein the locking head is adapted to the shape and position of the locking groove.

[0008] Preferably, the drive assembly includes a rotating head rotatably mounted inside the lock body, the rotating head having a keyhole inside, a connecting seat fixedly connected to the lower left end of the left slider, and the upper end of the rotating head being rotatably connected to the connecting seat via a rotating connector.

[0009] Preferably, the transmission assembly includes a gear rotatably mounted inside the lock body, the gear being meshed with a rack located below the right end of the left slider and above the left end of the right slider.

[0010] Preferably, the right slider has a horizontally designed sliding groove on its left side, and one end of the gear drive shaft is located in the sliding groove.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] 1. This application achieves linkage through the engagement of left and right sliders with gears, enabling simultaneous reverse movement of the sliders at both ends when the key is rotated, thus achieving bidirectional locking or unlocking. Compared to a unidirectional locking structure, the double-opening design is more stable when securing large items such as suitcases, locks faster, and reduces the hassle of multiple operations.

[0013] 2. In this application, the locking head and locking groove are precisely matched to ensure reliable locking. The sliding groove's limiting design for the gear drive shaft effectively prevents excessive movement of the right slider, ensuring structural durability and locking accuracy. In long-term use, the combination of limiting and linkage reduces wear and extends the lock's lifespan.

[0014] 3. In this application, both the lock body and the connecting buckle can be bolted to the roof beam or other locations, offering strong adaptability. The insertion frame guides the insertion, and locking or unlocking is achieved simply by turning the key, requiring no complex tools and allowing for quick and convenient operation, making it especially suitable for outdoor travel and frequent loading / unloading scenarios.

[0015] In summary, this double-opening locking mechanism combines the advantages of bidirectional synchronous locking, high-precision limiting, and convenient installation and operation. It not only improves locking efficiency but also ensures structural stability and durability, maintaining a safe and reliable fixing effect in various installation environments.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1 to 4 A double-opening lock mechanism includes a lock body 1 and a connecting buckle 2. The lock body 1 is usually fixedly installed on the roof beam or other places where the device needs to be installed by bolts. The connecting buckle 2 is fixedly installed on the four corners of the trunk or other places where the device needs to be installed by bolts. An insertion frame 3 is fixedly installed on one side of the top of the lock body 1. The lower end of the connecting buckle 2 is slidably inserted into the insertion frame 3 and has a locking groove 11. The locking groove 11 is horizontally designed.

[0023] The lock body 1 has a sliding cavity 10 inside. A left slider 5 is slidably installed on the left side of the sliding cavity 10, and a right slider 6 is slidably installed on the right side. A locking head 4 is fixedly installed on the upper right end of the left slider 5. The locking head 4 is adapted to the shape and position of the locking groove 11, so that the locking head 4 can be inserted into the locking groove 11 to limit and fix the connecting buckle 2 as it moves with the left slider 5. A rotating head 8 is rotatably installed inside the lock body 1 on the lower left side of the left slider 5. The rotating head 8 has a keyhole inside. After the user inserts the key, the rotating head 8 can be rotated by rotating the key. A connecting seat 9 is fixedly connected to the lower left end of the left slider 5. The upper end of the rotating head 8 is rotatably connected to the connecting seat 9 through a rotating connector, so that the rotating head 8 drives the left slider 5 to move horizontally back and forth while rotating.

[0024] Both the left slider 5 and the right slider 6 have racks at their closest ends. A gear 7 is located between the upper and lower racks. The gear 7 is rotatably mounted inside the lock body 1 and meshes with the upper and lower racks respectively, allowing the upper and lower racks to move horizontally in opposite directions. To limit the movement distance of the right slider 6, a horizontally designed sliding groove 12 is provided on the left side of the right slider 6, and one end of the gear 7's drive shaft is located in the sliding groove 12.

[0025] In operation, the lock body 1 is first fixedly installed at the location where the device is needed, such as on a roof beam, using bolts or similar means. Then, the connecting buckle 2 is inserted into the insertion frame 3. Subsequently, the operator inserts the key into the rotating head 8. The rotation of the rotating head 8 drives the left slider 5 to move to the left. As the left slider 5 moves, the locking head 4 moves synchronously, thus allowing the locking head 4 to insert into the locking groove 11 to limit and fix the connecting buckle 2. At the same time, with the cooperation of the gear 7 and the rack, the right slider 6 moves to the right. When it is necessary to unlock the device, the operator simply rotates the key in the opposite direction to make the rotating head 8 rotate in the opposite direction.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
