Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a padlock that integrates key unlocking and password unlocking. Background Technology

[0002] Padlocks are a common type of lock, often used on doors, boxes, or cabinets. Existing padlocks typically consist of two parts: a lock body and a locking bar (U-shaped or straight). When in use, the locking bar is passed through and hooked onto two lugs (located on the door and door frame, or on two separate doors). Traditional padlocks are usually mechanical or combination locks. Mechanical locks use a key to move the locking pin inside the padlock, disengaging it from the locking bar to unlock.

[0003] The combination lock has a combination wheel mechanism. When in use, each combination wheel is rotated to the correct position (i.e., the combination is correct), and then the push rod on the combination wheel mechanism is used to push the lock pin to unlock. However, if the user forgets the combination, the lock cannot be opened, which is inconvenient to use. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a padlock that integrates key unlocking and password unlocking. It can realize two independent unlocking functions: key unlocking and password unlocking. If the user forgets the password, they can unlock the padlock with the key, making it more convenient to use.

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

[0006] A padlock integrating key unlocking and combination unlocking includes a housing, and a locking bar, a locking pin, a first elastic element, a lock cylinder mechanism, and a combination wheel mechanism disposed on the housing;

[0007] The locking pin is linearly and movably connected to the housing, and the first elastic element makes the locking pin and the locking rod always tend to remain in a locked state.

[0008] The lock cylinder mechanism has a free-spinning lock cylinder, an annular sleeve, and a knob. One end of the free-spinning lock cylinder has an eccentric block that abuts against the lock pin. The annular sleeve is sleeved on the outside of the free-spinning lock cylinder. The knob is located at the other end of the free-spinning lock cylinder. The knob is at least partially located outside the housing. The knob can drive the annular sleeve, the free-spinning lock cylinder, and the eccentric block to rotate synchronously around the rotation center line of the knob.

[0009] The combination wheel mechanism is located on one side of the lock cylinder mechanism. The combination wheel mechanism has a push rod and a second elastic element. The second elastic element makes the push rod always tend to move towards the annular sleeve. The annular sleeve has a first slot and a second slot arranged at intervals around its circumference. One end of the push rod is engaged in the first slot or the second slot so that the knob is kept in the current position. When unlocking, the knob or key drives the eccentric block to rotate, so that the eccentric block drives the lock pin to move.

[0010] By incorporating a lock cylinder mechanism and a combination wheel mechanism, the lock cylinder mechanism includes a free-spinning lock cylinder, a ring sleeve, and a knob. One end of the free-spinning lock cylinder has an eccentric lever that abuts against the lock pin. The ring sleeve is fitted onto the outside of the free-spinning lock cylinder, and the knob is located at the other end of the free-spinning lock cylinder, with at least a portion of the knob located outside the housing. The ring sleeve has circumferentially spaced first and second slots. The knob can drive the ring sleeve, the free-spinning lock cylinder, and the eccentric lever to rotate synchronously around the knob's rotation center line. The combination wheel mechanism includes a insertion rod and a second elastic element. The insertion rod engages with either the first or second slot, holding the knob in its current position. In use, the combination wheel is rotated to the correct position, and then the knob is rotated to move the insertion rod from the first slot to the second slot, thus unlocking the lock. If the combination is forgotten, the key can be inserted into the free-spinning lock cylinder to rotate the eccentric lever, directly unlocking the lock. This achieves two independent unlocking functions: key unlocking and combination unlocking. Users can unlock the lock with the key if they forget their combination, making it more convenient.

[0011] In one embodiment, one end of the insertion rod has a locking block, the locking block has an arc-shaped surface on the side facing the annular sleeve, the arc-shaped surface protrudes in the direction close to the annular sleeve, and the openings of the first locking groove and the second locking groove are both open outward along the radial direction of the annular sleeve.

[0012] In one embodiment, the curvature of the arc surface is 1.6 rad to 2.0 rad.

[0013] In one embodiment, the housing has a main body and a rear cover, with a first receiving groove, a second receiving groove, and a third receiving groove formed between the main body and the rear cover. The locking pin and the first elastic element are both disposed in the first receiving groove, the free-spinning lock cylinder and the annular sleeve are both disposed in the second receiving groove, one end of the eccentric lever extends into the first receiving groove and abuts against the locking pin, and the combination wheel mechanism is disposed in the third receiving groove. The second receiving groove has a notch on the side near the third receiving groove for inserting a rod.

[0014] In one embodiment, both the first and second receiving slots are located on the rear cover. The password wheel mechanism is connected to the rear cover by a first screw. The first receiving slot opens upward to form an installation opening. A baffle is provided at the installation opening. The baffle is connected to the rear cover by a second screw.

[0015] In one embodiment, a limiting structure is provided between the lock cylinder mechanism and the third receiving groove, the limiting structure restricting the knob from rotating between unlocking and locking.

[0016] In one embodiment, the limiting structure includes an arc-shaped groove and a limiting block, wherein one of the arc-shaped groove and the limiting block is disposed on the third receiving groove and the other is disposed on the lock cylinder mechanism.

[0017] In one embodiment, the knob has a non-circular boss that protrudes radially outward on its circumference.

[0018] In one embodiment, the outer circumferential wall of the knob is provided with a plurality of raised strips or protrusions.

[0019] In one embodiment, the annular sleeve is integrally formed with the knob.

[0020] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, by setting a lock cylinder mechanism and a combination wheel mechanism, the lock cylinder mechanism has a free-spinning lock cylinder, a ring sleeve, and a knob. One end of the free-spinning lock cylinder has an eccentric block that abuts against the lock pin. The ring sleeve is sleeved on the outside of the free-spinning lock cylinder, and the knob is located at the other end of the free-spinning lock cylinder. The knob is at least partially located outside the housing. The ring sleeve has a first slot and a second slot arranged at intervals around its circumferential direction. The knob can drive the ring sleeve, the free-spinning lock cylinder, and the eccentric block to rotate synchronously around the rotation center line of the knob. The combination wheel mechanism has a rod and a second elastic element. The rod engages with the first slot or the second slot to keep the knob in its current position. In use, by rotating the combination wheel on the combination wheel mechanism to the correct position and then rotating the knob, the rod is moved from the first slot to the second slot to unlock. If the combination is forgotten, the key can be inserted into the free-spinning lock cylinder to drive the eccentric block to rotate and unlock directly. This allows for two independent unlocking functions: key unlocking and password unlocking. Users can unlock the door with the key if they forget their password, making it more convenient.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] like Figure 1-8 As shown, in the first embodiment, the present invention discloses a padlock that integrates key unlocking and password unlocking, including a housing 10, and a lock rod 20, a lock pin 30, a first elastic element 11, a lock cylinder mechanism 40, and a password wheel mechanism 50 disposed on the housing 10.

[0040] The locking pin 30 is linearly and movably connected to the housing 10 in the left-right direction. The first elastic element 11 makes the locking pin 30 and the locking rod 20 always tend to maintain a locked state. The first elastic element 11 is a return spring, and the locking rod 20 is a U-shaped locking rod 20.

[0041] The lock cylinder mechanism 40 has a free-spinning lock cylinder 41, an annular sleeve 42, and a knob 43. The annular sleeve 42 and the knob 43 are separately arranged. One end of the free-spinning lock cylinder 41 has an eccentric lever 411 that abuts against the locking pin 30. The annular sleeve 42 is sleeved on the outside of the free-spinning lock cylinder 41. The knob 43 is located at the other end of the free-spinning lock cylinder 41. The knob 43 is at least partially located outside the housing 10. The knob 43 can drive the annular sleeve 42, the free-spinning lock cylinder 41, and the eccentric lever 411 to rotate synchronously around the rotation center line of the knob 43. The front side of the housing 10 is provided with a through hole 12. The other end of the free-spinning lock cylinder 41 extends out of the through hole 12. The part of the free-spinning lock cylinder 41 extending out of the through hole 12 is connected to the knob 43.

[0042] The combination wheel mechanism 50 is located on one side of the lock cylinder mechanism 40. The combination wheel mechanism 50 and the lock cylinder mechanism 40 are distributed vertically. The structure of the combination wheel mechanism 50 is existing technology. The combination wheel mechanism 50 has a plug rod 51 and a second elastic element (not shown). The second elastic element is a return spring. The second elastic element makes the plug rod 51 always tend to move towards the annular sleeve 42. The annular sleeve 42 has a first slot 421 and a second slot 422 arranged circumferentially. One end of the plug rod 51 is engaged in the first slot 421 or the second slot 422 so that the knob 43 is kept in the current position. When unlocking, the knob 43 or the key drives the eccentric block 411 to rotate, so that the eccentric block 411 drives the lock pin 30 to move. It should be noted that when unlocking with the key, during the process of the key driving the eccentric block 411 to rotate, the knob 43 and the annular sleeve 42 remain stationary.

[0043] One end of the insertion rod 51 has a locking block 52. The side of the locking block 52 facing the annular sleeve 42 has an arc-shaped surface 521. The arc-shaped surface 521 protrudes towards the annular sleeve 42. The openings of the first locking groove 421 and the second locking groove 422 are both open outward along the radial direction of the annular sleeve 42. By setting the arc-shaped surface 521, and utilizing the guiding effect of the arc-shaped surface 521, when the knob 43 drives the annular sleeve 42 to rotate, the opening edge of the first locking groove 421 or the second locking groove 422 slides into contact with the arc-shaped surface 521. The locking block 52 is subjected to the radial outward pressure of the annular sleeve 42, causing the insertion rod 51 to overcome the elastic force of the second elastic element and move away from the annular sleeve 42. This facilitates the locking block 52 to enter and exit the first locking groove 421 or the second locking groove 422, thereby making the knob 43 rotate smoothly and easy for the user to operate.

[0044] The arc of the arc surface 521 is 1.6 rad to 2.0 rad, preferably 1.7 rad. The formula for calculating the arc is: arc = arc length / radius. With an arc of 1.6 rad to 2.0 rad, the locking block 52 has good locking stability with the first locking slot 421 or the second locking slot 422, so that the locking block 52 has both good guiding function and locking stability.

[0045] The housing 10 has a main body 101 and a rear cover 102. A first receiving groove 13, a second receiving groove 14, and a third receiving groove 15 are formed between the main body 101 and the rear cover 102. The locking pin 30 and the first elastic element 11 are both disposed in the first receiving groove 13. The free-spinning lock cylinder 41 and the annular sleeve 42 are both disposed in the second receiving groove 14. One end of the eccentric lever 411 extends into the first receiving groove 13 and abuts against the locking pin 30. The combination wheel mechanism 50 is disposed in the third receiving groove 15. The second receiving groove 14 has a notch 141 for inserting the rod 51 to extend into on the side near the third receiving groove 15. The through hole 12 is disposed on the front side of the main body 101 and is directly opposite the second receiving groove 14.

[0046] The first receiving groove 13 and the second receiving groove 14 are both provided on the rear cover 102. The combination wheel mechanism 50 is connected to the rear cover 102 by a first screw. The first receiving groove 13 opens upward to form an installation port 131. A baffle 16 is provided at the installation port 131. The baffle 16 is connected to the rear cover 102 by a second screw. By providing the first receiving groove 13 and the second receiving groove 14 on the rear cover 102, connecting the combination wheel mechanism 50 to the rear cover 102 by a first screw, and connecting the baffle 16 to the rear cover 102 by a second screw, the locking pin 30 and the first elastic element 11 can be inserted into the first receiving groove 13 through the installation port 131. Thus, during production and assembly, the locking pin 30, the first elastic element 11, the lock cylinder mechanism 40, and the combination wheel mechanism 50 can be pre-assembled onto the rear cover 102. Then, the rear cover 102 is connected and fixed to the main body 101 to complete the assembly, which is convenient.

[0047] A limiting structure is provided between the lock cylinder mechanism 40 and the third receiving groove 15. The limiting structure restricts the knob 43 from rotating between unlocking and locking. By setting the limiting structure, the knob 43 is restricted from rotating between unlocking and locking, thereby facilitating the user to unlock and lock.

[0048] The knob 43 rotates at an angle of 90 degrees between unlocking and locking. The included angle between the first slot 421 and the second slot 422 is 90 degrees. When the knob 43 rotates from 0 degrees to 90 degrees, the insertion rod 51 moves from the first slot 421 to the second slot 422.

[0049] The limiting structure includes an arc-shaped groove 142 and a limiting block 423. One of the arc-shaped groove 142 and the limiting block 423 is located on the third receiving groove 15, and the other is located on the lock cylinder mechanism 40. For example, the arc-shaped groove 142 is located on the inner wall of the receiving groove, and the limiting block 423 is located on the lock cylinder mechanism 40. During assembly, the limiting block 423 is located in the arc-shaped groove 142. Specifically, the limiting block 423 can be located on the free-spinning lock cylinder 41, the annular sleeve 42, or the knob 43. Preferably, the limiting block 423 is located on the annular sleeve 42, and at least one limiting block 423 is provided. When the knob 43 rotates, the limiting block 423 moves along the arc-shaped groove 142. When the limiting block 423 abuts against the inner wall of one end of the arc-shaped groove 142, the knob 43 stops rotating. It can be understood that the positions of the arc-shaped groove 142 and the limiting block 423 are interchangeable.

[0050] The knob 43 has a non-circular boss 431 protruding radially outward on its circumference; the non-circular boss 431 makes it convenient for the user to rotate the knob 43 to unlock or lock by holding the non-circular boss 431.

[0051] like Figure 9-13 As shown, in the second embodiment, the difference from the first embodiment is that the locking pin 30 is linearly and movably connected to the housing 10 in the vertical direction, the locking rod 20 is a straight locking rod 20, the combination wheel mechanism 50 and the lock cylinder mechanism 40 are distributed in the horizontal direction, the annular sleeve 42 and the knob 43 are integrally formed, and the outer circumferential wall of the knob 43 is provided with a plurality of protrusions 432 or protrusions. The protrusions 432 extend along the axial direction of the knob 43, and when the knob 43 is rotated, the protrusions 432 play an anti-slip role.

[0052] The baffle 16 is not provided at the mounting port 131. One end of the locking pin 30 extends upward through the mounting port 131. The second receiving groove 14 is provided on the main body 101. The second receiving groove 14 penetrates the front outer wall of the main body 101 to form the through hole 12. The password wheel mechanism 50 is connected to the main body 101 by a third screw.

[0053] How to use this utility model:

[0054] Unlocking with a key: After inserting the key into the idle lock cylinder 41, rotate the key so that the key drives the eccentric lever 411 and the locking pin 30 to move in sequence. The locking pin 30 disengages from the locking rod 20 to unlock. When locking, the locking pin 30 and the locking rod 20 remain engaged under the elastic force of the first elastic element 11.

[0055] Unlocking with Password: In the locked state, the locking block 52 engages in the first slot 421. After the password on the password wheel mechanism 50 is correctly adjusted, turn the knob 43 clockwise. The knob 43 drives the idle lock cylinder 41, the ring sleeve 42, and the eccentric lever 411 to rotate. The eccentric lever 411 drives the lock pin 30 to move. The lock pin 30 disengages from the lock rod 20, thus unlocking the device. When the ring sleeve 42 rotates, it presses against the arc-shaped surface 521 on the locking block 52, causing the locking block 52 to drive the insertion rod 51 to overcome the elastic force of the second elastic element and move away from the ring sleeve 42. After the locking block 52 disengages from the first slot 421, it enters the second slot 422. When the locking block 52 engages with the second slot 422, it is in the unlocked state. When locking, turn the knob 43 counterclockwise, and the locking block 52 re-engages in the first slot 421.

[0056] In summary, this utility model has significant advantages and beneficial effects compared with the prior art. Specifically, by setting a lock cylinder mechanism 40 and a combination wheel mechanism 50, the lock cylinder mechanism 40 has a free-spinning lock cylinder 41, an annular sleeve 42, and a knob 43. One end of the free-spinning lock cylinder 41 has an eccentric lever 411 that abuts against the locking pin 30. The annular sleeve 42 is sleeved on the outside of the free-spinning lock cylinder 41, and the knob 43 is located at the other end of the free-spinning lock cylinder 41. The knob 43 is at least partially located outside the housing 10. The annular sleeve 42 has a first slot 421 and a second slot 422 arranged circumferentially. The knob 43... The ring sleeve 42, the free-spinning lock cylinder 41, and the eccentric lever 411 can be driven to rotate synchronously around the rotation center line of the knob 43. The combination wheel mechanism 50 has a rod 51 and a second elastic element. The rod 51 engages with either the first slot 421 or the second slot 422 to keep the knob 43 in its current position. In use, by rotating the combination wheel on the combination wheel mechanism 50 to the correct position and then rotating the knob 43, the rod 51 is moved from the first slot 421 to the second slot 422 to unlock. If the combination is forgotten, the key can be inserted into the free-spinning lock cylinder 41 to rotate the eccentric lever 411 to unlock directly. This realizes two independent unlocking functions: key unlocking and combination unlocking. If the user forgets the combination, they can unlock with the key, making it more convenient to use.

[0057] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
