Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4 The present embodiment provides a rust-proof password padlock, comprising a lock body 100, a lock beam 300 is rotatably inserted on the surface of the lock body 100, a first cavity 304 is defined inside the lock body 100, one end of the lock beam 300 extends to the inside of the first cavity 304 and is fixedly connected to a locking assembly for locking the lock beam 300, a third cavity 201 is defined inside the lock body 100, an oil nang 204 is provided in the inner cavity of the third cavity 201, an oil nang 204 is connected to the bottom of the oil nang 204 with an oil pipe 205, the other end of the oil pipe 205 extends to the inner cavity of the first cavity 304, a second cavity 500 is defined inside the lock body 100 and located on one side of the third cavity 201, a transmission column 200 is slidably connected to the inner cavity of the second cavity 500, one end of the transmission column 200 passes through the second cavity 500 and abuts against the surface of the oil nang 204, and the other end of the transmission column 200 passes through the second cavity 500 and extends to the outside of the lock body 100.
[0023] The utility model presses the transmission column 200 through the setting of the oil naan 204, drives one end of the transmission column 200 to move to one side, squeezes the oil naan 204, and injects the anti-rust oil in the oil naan 204 into the first cavity 304 through the oil pipe 205, thereby performing anti-rust treatment on the locking component in the first cavity 304 for locking the lock beam 300, thereby greatly improving the service life of the lock.
[0024] Specifically, a plurality of groups of code wheels 302 are rotatably sleeved on one end surface of the lock beam 300 located inside the first cavity 304, a blocking block 303 is fixedly installed in the inner cavity of the code wheel 302, and a vertically arranged slide groove 301 is opened on one end surface of the lock beam 300 located inside the first cavity 304. In the above design, the code wheel 302 is rotated to a corresponding position, so that the blocking block 303 in the inner cavity of the code wheel 302 is arranged in a straight line, thereby pulling the lock beam 300 upward, so that the inner cavity of the slide groove 301 on the surface of the lock beam 300 slides over the surface of the blocking block 303, thereby releasing the fixing of the lock beam 300.
[0025] Specifically, a guide plate 501 is fixedly sleeved on the surface of the transmission column 200 located in the second cavity 500, a spring 503 is sleeved on the surface of the transmission column 200 and located on one side of the guide plate 501, and the two ends of the spring 503 are respectively connected to the inner wall of the second cavity 500 and one side surface of the guide plate 501, and one end of the transmission column 200 is fixedly connected to a pressing plate 502, and the pressing plate 502 contacts the surface of the oil naan 204. The above design increases the contact area with the oil naan 204 through the setting of the pressing plate 502, and improves the pressing force on the oil naan 204.
[0026] Specifically, the top of the oil naan 204 is connected to a liquid adding pipe 203, one end of which passes through the lock body 100 and is threadedly connected to a sealing bolt 202. The above design, through the arrangement of the sealing bolt 202 and the liquid adding pipe 203, removes the sealing bolt 202, and flows into the inner cavity of the oil naan 204 through the liquid inlet of the liquid adding pipe 203, thereby facilitating the user to replenish oil, thereby extending the service life of the lock.
[0027] Specifically, a hinge 400 is connected to one side of the lock body 100, and a cover plate 401 is connected to the rotating end of the hinge 400. The above design prevents rainwater from entering the lock body 100 through the gap between the lock body 100 and the code wheel 302 through the arrangement of the cover plate 401.
[0028] Specifically, a damping shaft 403 is fixedly mounted on the surface of the lock body 100, and a fixing block 402 is fixedly connected to the rotating end of the damping shaft 403, and the surface of the fixing block 402 penetrates the cover plate 401, and one side of the fixing block 402 is in close contact with the outer surface of the cover plate 401. By setting the damping shaft 403 and the fixing block 402, the fixing block 402 is rotated around the damping shaft 403 to fix the cover plate 401, thereby ensuring that the cover plate 401 will not shake due to external forces.
[0029] Working principle: first rotate the fixing block 402 to flip the cover plate 401 upwards, then rotate the code wheel 302 in sequence, rotate the code wheel 302 to the corresponding position, so that the blocking block 303 in the inner cavity of the code wheel 302 is arranged in a straight line, thereby pulling the lock beam 300 upwards, so that the inner cavity of the slide groove 301 on the surface of the lock beam 300 slides over the surface of the blocking block 303, thereby releasing the fixation of the lock beam 300, and rotating the lock beam 300 to open the lock. During the operation, the transmission column 200 is pressed, driving the pressure plate 502 fixedly installed at one end of the transmission column 200 to move to one side, thereby squeezing the oil naan 204, and injecting the anti-rust oil in the oil naan 204 into the first cavity 304 through the oil pipe 205, thereby performing anti-rust treatment on the locking component in the first cavity 304 for locking the lock beam 300. When the anti-rust oil in the oil naan 204 is used up, remove the sealing bolt 202 and add oil to the oil naan 204 through the liquid filling pipe 203.
[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
