Technical Field
[0001] The utility model relates to the technical field of shared bicycle accessories, in particular to a shared bicycle lock that can be oiled regularly. Background Art
[0002] Bicycle locks can easily become stuck over time due to environmental factors and frequency of use. Over time, dust, dirt, and rust accumulate inside the lock cylinder. These impurities increase friction, making unlocking difficult. Especially in humid or inclement weather, the lock cylinder is susceptible to corrosion, further exacerbating the problem. If not addressed promptly, this condition can completely prevent the lock cylinder from rotating, impacting use and even preventing the lock from being unlocked. This is particularly true in shared bike scenarios, where shared bikes are used much more frequently than personal bikes. Frequent locking and unlocking by a large number of users increases wear and tear on the lock's interior. Accumulated dust and dirt quickly build up, increasing friction between the lock cylinder and the lock body, making it more susceptible to jamming. Furthermore, shared bikes are constantly outdoors, exposed to a variety of weather conditions. Natural factors like rain, snow, and mud accelerate rust and corrosion. Compared to personally owned bikes, locks on shared bikes corrode and wear more quickly, making the lock cylinder more susceptible to jamming.
[0003] Patent application number CN202322762903.0 discloses a rainproof bicycle lock, specifically comprising a lock and a waterproof device. The lock is a conventional bicycle lock, wherein a ring of protrusions is provided below the outer side of the lock's keyhole, and a ring of grooves is provided above the protrusions. The waterproof device is provided in the groove. The waterproof device comprises a fixed block and a rainproof sheet. The fixed block is a circular protrusion with a notch, and its size matches the size of the groove, allowing it to snap into the groove. The rainproof sheet is adhered above the fixed block. The rainproof sheet has a pocket structure, and a connecting block is sewn at its lower edge. The connecting block is glued to the groove with strong glue, and the size and shape of the connecting block are the same as those of the notch of the fixed block. The utility model provides a waterproof device on the bicycle lock. When the bicycle is locked, the waterproof device can be placed in the keyhole to prevent rainwater from falling into the keyhole and avoid rust, thus meeting people's needs. Although the rainproof structure is optimized, the problem of the lock cylinder getting stuck is not solved. Utility Model Content

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0039] To prevent the lock cylinder from getting stuck or becoming jammed, it's essential to regularly lubricate the lock mechanism. Lubricant effectively penetrates the lock cylinder, removing accumulated dirt and rust while forming a protective film that reduces friction and corrosion. This not only maintains smooth lock cylinder operation and extends the life of the lock, but also ensures smooth unlocking in an emergency, enhancing safety. Therefore, regular lubrication is not only essential for lock maintenance but also ensures convenience and safety during cycling.
[0040] Refer to the attached Figure 1 To the attached Figure 8 As shown, it is particularly noted that Figure 7The dotted lines in the figure represent the deeper first slide groove 501 and the third slide groove 401. A shared bicycle lock that can be oiled regularly includes a lock body 1, a lock pin 2 and a locking mechanism. The locking mechanism includes a locking pin 3. The locking pin 3 can be downwardly absorbed into the locking recess 201. The locking recess 201 is provided with a vertical limiting sliding surface 2011 corresponding to the locking pin 3. The limiting sliding surface 2011 has a smooth surface, which is convenient for the locking pin 3 to disengage from the locking recess 201 when moving upward. The locking pin 3 includes a horizontal rod 301 protruding outward, and the horizontal rod 301 is supported by a support arm 4. The support arm 4 is connected to a sliding tooth plate 5 on the side away from the locking pin 3. The sliding tooth plate 5 is meshed with a first gear 601. The first gear 601 is provided on the output shaft 602 of the first motor 6. The back of the sliding tooth plate 5 is provided with a first slide groove 501, and the back plate 7 A first protruding rib 701 protrudes from the first chute 501, allowing the first chute 501 to reciprocate up and down on the first protruding rib 701. An oil tank 8 is provided at the top of the first protruding rib 701. An oil outlet 801 is provided at the bottom of the oil tank 8, corresponding to the surface of the first protruding rib 701. An air inlet 802 is provided at the top of the oil tank 8, which is blocked by a plug 9. When the plug 9 is removed from the air inlet 802, air enters the oil tank through the air inlet 802, exerting pressure on the oil in the oil tank 8. The lubricating oil in the oil tank 8 flows out of the oil outlet 801 and onto the surface of the first protruding rib 701. The lubricating oil coating the surface of the first protruding rib 701 reduces friction with the sliding tooth plate 5, thereby better controlling the unlocking and locking tasks. The plug 9 is controlled by a second motor 10 to insert or remove the plug.
[0041] In the shared bicycle lock, an oil tank 8 storing lubricating oil is optimized in design, and a blocking plug 9 that can be pulled out from the oil tank 8 is designed. The blocking plug 9 is inserted into the oil tank 8 to block the oil tank, which is in a vacuum state. Furthermore, when the oil in the oil tank 8 is used up, the oil tank installation window 704 is opened on the back plate 7 to replace the oil tank 8. When the blocking plug 9 is pulled out from the oil tank 8, air enters the oil tank 8 from the air inlet. By utilizing the air pressure difference, the lubricating oil flows out from the oil outlet 801 and flows to the connection between the first slide groove 501 and the first protruding rib 701, lubricating the first slide groove 501 and the first protruding rib 701, reducing the friction between the first slide groove 501 and the first protruding rib 701, so that the first slide groove 501 and the first protruding rib 701 can slide smoothly, better control the unlocking and locking tasks, and protect the lock at the same time, extending the service life of the lock.
[0042] At the same time, a third slide groove 401 is recessed on the side of the support arm 4 facing the back plate 7. The third slide groove 401 is slidably connected with the third protruding rib 703. A guide channel 13 is designed between the third slide groove 401 and the first slide groove 501 to guide the lubricating oil flowing into the first slide groove 501 into the third slide groove 401. The guide channel 13 includes an inlet 1301 and an outlet 1302. The inlet 1301 is provided at the top of the sliding tooth plate 5, and the outlet 1302 is connected with the third slide groove 401. The lubricating oil flows from the inlet 1301 into the guide channel 13, passes through the guide channel 13, and finally flows to the third slide groove 401 and the three protruding ribs 703 through the outlet 1302, thereby lubricating and protecting the third slide groove 401 and the three protruding ribs 703.
[0043] The blocking plug 9 is arranged on the side of the vertical plate 901 facing the oil tank 8, and convex strips 902 are provided on both sides of the vertical plate 901. The outer shell of the oil tank 8 is provided with a protruding limiting slide 803 corresponding to the convex strips 902. The convex strips 902 are inserted into the limiting slide 803 and can slide in a limited position, thereby limiting the movement of the entire vertical plate 901, thereby ensuring that after the blocking plug 9 is pulled out from the air inlet hole 802, it can be smoothly reinserted into the air inlet hole 802 under the control of the second motor 10, so as to prevent excessive outflow of lubricating oil.
[0044] The top of the vertical plate 901 is connected to the top sliding tooth plate 11, and the top sliding tooth plate 11 is engaged with the second gear 1001. The top sliding tooth plate 11 is recessed into one end toward the back plate 7 and is provided with a second sliding groove 1101. The back plate 7 is protruded with a second protruding rib 702 to match the second sliding groove 1101. The second sliding groove 1101 is plugged into the second protruding rib 702.
[0045] The one-way sliding distance of the protruding strip 902 is greater than the length of the plug 9 extending into the air inlet 802 .
[0046] A sealing ring 12 is provided at the connection between the air inlet 802 and the plug 9 and on the side facing the inner cavity of the oil tank 8.
