Description

Technical Field

[0001] This utility model relates to the field of helmet locks and related technologies, specifically to a locking and positioning structure that prevents jamming. Background Technology

[0002] The locking mechanism is a purely mechanical locking device. Its core function is to physically position the helmet after the user places it in the basket or designated location, using an L-shaped guide plate or guide rib to ensure that the helmet's locking hole and locking pin are precisely aligned. Then, the user can manually press, rotate, or pull the handle or lever of the lock to directly drive the locking tongue or locking pin to overcome the spring resistance and accurately insert it into the locking hole or slot at the bottom of the helmet, thus completing the physical locking.

[0003] With the increasing popularity of electric bicycles and shared electric bicycles, helmets and their anti-theft locks have emerged to ensure riding safety and convenience for users. Currently, most helmet locks on the market, especially those used in shared vehicles and private electric bicycles, use a mechanical locking tongue inserted into a pre-set hole at the bottom of the helmet for locking.

[0004] However, these locks face a common and thorny problem in practical applications: due to long-term parking and use in outdoor environments, the lock's keyhole, bolt, and internal transmission mechanism are completely exposed to natural conditions. Dust, mud, sand, tiny impurities, rainwater, and dew in the air can easily penetrate the lock body through gaps in the keyhole. These foreign objects accumulate in the bolt's sliding track, gear meshing surfaces, or spring return mechanism, solidify due to moisture, and may even cause metal parts to rust. When the user performs locking or unlocking operations again, these intruding impurities significantly increase the resistance to mechanical movement, hindering the normal extension and retraction of the bolt, thus causing the lock body to jam, move slowly, or even completely seize and fail. This jamming problem caused by external environmental pollution not only seriously affects the user experience and reduces the reliability and lifespan of the lock, but also poses a risk to the helmet's anti-theft function. Therefore, an anti-jamming locking and positioning structure is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-jamming locking structure, which improves the smoothness of locking operation and solves the problem that dust, mud, sand, tiny impurities, rainwater, and dew in the air can easily enter the lock body through the gaps in the keyhole during use. These foreign objects can accumulate and solidify in the sliding track of the bolt, the gear meshing surface, or the spring return mechanism, and may even cause corrosion of metal parts. When the user performs locking or unlocking operations again, these intruding impurities will significantly increase the resistance to mechanical movement, hindering the normal extension and retraction of the bolt, thus causing serious problems such as lock body jamming, sluggish operation, or even complete jamming and failure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A locking and positioning structure to prevent jamming includes a lock body and a lock cylinder. The lock body has a locking structure inside and a protective structure on its outer wall. The protective structure includes a fixed protective cover fixedly connected to the bottom of the lock body, a movable protective cover movably connected to the top of the lock body, a sealing frame fixedly connected to the bottom of the movable protective cover, mounting seats fixedly connected to both the front and rear sides of the movable protective cover, a connecting rod fixedly connected to the bottom of the mounting seat, fixed seats fixedly connected to both the front and rear sides of the fixed protective cover, two locking springs fixedly connected inside the fixed seats, locking rods fixedly connected to opposite ends of the two locking springs, and locking balls fixedly connected to opposite ends of the two locking rods.

[0007] Furthermore, the locking structure includes a rotating shaft located at the bottom of the lock cylinder, a gear fixedly connected to the outer peripheral wall of the rotating shaft, two toothed plates slidably connected inside the lock body, an adjusting rod fixedly connected to the opposite side of each of the two toothed plates, a lock head fixedly connected to the end of the adjusting rod away from the toothed plate, and elastic locking blocks fixedly connected to the top and bottom of the lock head.

[0008] Furthermore, the gear and the toothed plate mesh with each other, the lock cylinder is located inside the lock body, and the rotating shaft is rotatably connected inside the lock body.

[0009] Furthermore, the top and bottom of the adjusting rod are fixedly connected to limit slides, and the lock body has a slide groove inside. The limit slide is slidably connected inside the slide groove, and the size of the limit slide is adapted to the slide groove.

[0010] Furthermore, the sealing frame is movably connected to the top of the fixed protective cover, and the fixed protective cover and the movable protective cover enclose the lock body. Rectangular through holes are provided on both the left and right sides of the fixed protective cover.

[0011] Furthermore, the mounting base has a slot inside, and the connecting rod is inserted into the slot, with the connecting rod being adapted to the size of the slot.

[0012] Furthermore, both sides of the connecting rod are provided with arc-shaped grooves, and the locking ball is engaged inside the arc-shaped groove, with the size of the locking ball matching that of the arc-shaped groove.

[0013] Furthermore, the fixed base has two movable slots inside, and the locking spring, locking rod and locking ball are all connected to the movable slots by sliding grooves.

[0014] Compared with the prior art, this utility model provides an anti-jamming locking and positioning structure, which has the following beneficial effects: This anti-jamming locking and positioning structure uses a lock cylinder, rotating shaft, gears, toothed plate, and adjusting rod to move two lock heads. The two lock heads are inserted into the helmet to fix it in place for anti-theft purposes. The lock body is wrapped by a fixed protective cover, a movable protective cover, and a sealing frame, which greatly reduces the impact of external factors on the lock cylinder. The fixed protective cover and the movable protective cover are locked together by a connecting rod, a locking spring rod, and a locking ball, which improves the stability of the movable protective cover installation. This not only achieves the anti-jamming effect but also facilitates the positioning and fixing of the helmet. Attached Figure Description
