Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a password lock capable of switching working modes. Background Art

[0002] A combination lock is a type of lock that uses a series of numbers or symbols to open. Combination locks can be divided into: mechanical combination locks, digital combination locks, and so on.

[0003] The combination of a combination lock is usually just a permutation rather than a real combination. Some combination locks only use a turntable to rotate several discs or cams inside the lock; some combination locks rotate a set of dial rings with numbers engraved on them to directly drive the mechanism inside the lock.

[0004] In order to ensure personal privacy and personal property safety, people generally lock suitcases or cabinets at home. In order to increase the complexity of unlocking, mechanical password locks are usually used. The mechanical locks are locked by a password wheel, thereby increasing the difficulty of unlocking and ensuring its safety.

[0005] In the prior art, this type of lock composed of a mechanical lock and a password lock can usually be changed by operating the password lock, which is relatively arbitrary; the hidden danger is that during the unlocking process of the password lock, the password lock may be accidentally changed by entering the code change mode due to accidental touch.

[0006] For consumers who use it for personal use, this type of lock has a certain degree of instability. Utility Model Content

[0045] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0046] like Figure 1-9 As shown, the following embodiment discloses a password lock with switchable working modes.

[0047] Example 1

[0048] A password lock 300 capable of switching working modes, comprising:

[0049] A lock housing, which is formed by combining a panel 110 and a bottom housing 120 to form a housing having a lock cavity;

[0050] The mechanical lock 200 is arranged through the lock housing, and the rear end is connected with a lock plate 400 for locking with an external door cabinet; by turning the knob on the mechanical lock 200, the lock plate 400 is driven to rotate to unlock or lock;

[0051] The combination lock 300 includes a wheel set 320 and a lock rod 310. The lock rod 310 is arranged in the radial direction of the mechanical lock 200 and can lock the mechanical lock 200.

[0052] The combination lock 300 further includes a mode switching assembly 500, which includes at least an actuating component 510, a first end of which can be moved by an external force, and a stopper portion capable of accommodating the actuating component 510 is provided on the combination lock 300;

[0053] The actuating member 510 has at least two position states: a private mode and a public mode;

[0054] In the private mode, the actuating component 510 limits the position of the character wheel set 320, and the combination lock 300 cannot be changed;

[0055] In the public mode, the actuating member 510 is withdrawn from the combination lock 300, and the combination lock 300 can change the password.

[0056] The above is the basic solution of this embodiment.

[0057] Specific reference Figure 1 As shown, in this embodiment, the mechanical lock 200 passes through the lock housing, and the tail portion extends out of the lock housing, including a lock core and a lock sleeve, and a lock plate 400 is connected to the lock core; a plurality of blades are arranged in the lock core, so that the lock core and the lock sleeve can be locked and unlocked;

[0058] A key hole is provided on the front end surface of the lock core. Inserting a key can drive the blade to achieve locking and unlocking between the lock core and the lock sleeve.

[0059] At the same time, the combination lock 300 is arranged on one side of the mechanical lock 200. In this embodiment, it is arranged below the mechanical lock 200, and the lock rod 310 is perpendicular to the axis of the mechanical lock 200; the lock rod 310 can move along its own axis to achieve locking and unlocking with the mechanical lock 200;

[0060] The code change of the combination lock 300 is achieved by changing the position of the word wheel set 320 on the lock rod 310.

[0061] The specific connection structure and code changing method of the combination lock 300 and the mechanical lock 200 are consistent with those in the prior art and will not be described in detail here.

[0062] In this embodiment, a mode switching assembly 500 is further provided. When the mode switching assembly 500 is in the private mode, the second end of the actuating member 510 extends into the stopper portion to stop the movement of the character wheel set 320, so that the character wheel set 320 of the combination lock 300 cannot move along the lock rod 310 or rotate around its own central axis, thereby making it impossible to change the code. Figure 3 As shown;

[0063] When the mode switching assembly 500 is in the public mode, the actuating member 510 is not in contact with the combination lock 300, and the combination lock 300 is consistent with the conventional combination lock 300, and the code can be changed by moving or rotating the character wheel group 320. Figure 2 shown.

[0064] In this embodiment, the code changing method is that the actuating component 510 limits the movement of the character wheel set 320 on the locking rod 310, so that the character wheel 322 and the character wheel core 321 of the character wheel set 320 cannot be separated, thereby preventing the code changing.

[0065] Specifically, the mode switching assembly 500 further includes an operating component 520 , a first end of the operating component 520 extends out of the lock housing for manual operation, and a driving structure is provided between the second end and the actuating component 510 to push the actuating component 510 .

[0066] Specific reference Figure 4 As shown, the operating component 520 extends out of the lock housing and is provided with an operating portion, and the user operates the operating component 520 by driving the operating portion; when the operating component 520 moves, the actuating component 510 is driven, so that the actuating component 510 extends into the actuating portion to limit the character wheel set 320.

[0067] Preferably, the operating portion in this embodiment is configured as a strip-shaped operating groove 521 , and the operating component 520 is movable by rotation. The user rotates the operating component 520 with the aid of a tool, so that the operating component 520 drives the actuating component 510 .

[0068] Since the operating component 520 is rotatable, the rotation needs to be converted into linear movement of the actuating component 510. The specific implementation method of this embodiment to solve this problem is as follows: the first end of the operating component 520 is formed with a driving head 522, and the driving head 522 is provided with a driving part 522.1; the first end of the actuating component 510 is provided with a contact part that cooperates with the driving part 522.1.

[0069] Preferably, the driving portion 522.1 is a threaded driving surface provided on the driving head 522; the abutting portion is an abutting surface 511 matched with the threaded surface;

[0070] The driving part 522.1 rotates under the action of external force, pushing the abutting part toward one side of the combination lock 300.

[0071] The part on the threaded driving surface closest to the abutment surface 511 is set as a high point, and the other end is set as a low point; for the same point on the abutment surface 511, in the initial state, the low point is in contact with the part, and as the operating component 520 rotates, the position of the point in contact with it gradually rises until the high point reaches the part, and since the high point is closer to the combination lock 300 in the horizontal direction, the abutment surface 511 is pushed toward the side of the combination lock 300, that is, the actuating component 510 is pushed toward the side of the combination lock 300.

[0072] Preferably, in this embodiment, the stopper portion is located at the side of the word wheel set 320 close to the lock core and close to the first word wheel 322 to limit the axial movement of the word wheel set 320 .

[0073] Reference Figure 5 As shown, when changing the code of the combination lock 300, the word wheel set 320 is unlocked, so that the word wheel 322 and the word wheel core 321 of the word wheel set 320 are in a separable state, and at the same time, the spring at the bottom of the combination wheel pushes the word wheel core 321 toward the head side of the lock rod 310, that is, toward the side of the combination lock 300, so that the word wheel core 321 is disengaged from the word wheel 322; at this time, the word wheel 322 can rotate freely under the action of external force to change the code;

[0074] In this embodiment, the stopper is arranged at the head of the lock rod 310 and is located at the side of the first character wheel set 320. When the second end of the actuating member 510 is located at the stopper, its end stops the character wheel core 321, and the spring at the tail of the combination lock 300 cannot push the character wheel core 321 out of the character wheel 322, thereby preventing the character wheel 322 from rotating freely and failing to change the code.

[0075] Preferably, refer to Figure 5 As shown, a cut surface is provided on the head of the locking rod 310 , and the second end of the actuating portion can extend into the cut surface to contact and stop the locking rod 310 .

[0076] When the lock needs to be switched from private mode to public mode, the operating component 520 is rotated to rotate the driving part 522.1 as well. To achieve automatic withdrawal of the actuating part, in this embodiment, a reset component is further provided on the actuating component 510, and the reset component holds the actuating component 510 toward the side away from the lock core.

[0077] Preferably, in this embodiment, the reset component is a reset spring 530. When the actuating component 510 is not supported by the driving head 522, the reset spring 530 resets and pushes the actuating component 510 outward, so that the actuating component 510 escapes from the stop position.

[0078] In this embodiment, in order to avoid the interference of the reset spring 530 with the combination lock 300, an abutment block 600 is provided at the head of the lock rod 310, and the reset spring 530 is supported between the abutment block 600 and the actuating member 510. Figure 7 shown.

[0079] In this embodiment, in order to prompt the user of the rotation position, a limiting groove 121.1 is set on the inner wall of the bottom shell 120, and a limiting protrusion 523.1 cooperating with the limiting groove 121.1 is provided on the operating part 520. The limiting protrusion 523.1 rotates with the operating part 520 and is limited in the limiting groove 121.1.

[0080] Reference Figure 6 As shown, in this embodiment, a limit plate 121 is provided on the shell seat, and the limit plate 121 is fixed to the shell seat by screws; a limit groove 121.1 is provided on the limit plate 121, and is an arc-shaped groove; a rotation groove is provided on the inner wall of the limit plate 121, and the arc-shaped groove is connected with the outer periphery of the rotation groove;

[0081] At the same time, a rotating ring 523 is provided on the operating member 520, and a limiting protrusion 523.1 is connected to the outer periphery of the rotating ring 523;

[0082] During assembly, the rotating ring 523 is embedded in the rotating groove, and the limiting protrusion 523.1 is located in the limiting groove 121.1. The rotation range of the limiting protrusion 523.1 is only within the range of the limiting groove 121.1, thereby limiting the rotation range of the operating component 520.

[0083] Example 2

[0084] This embodiment is an improvement made on the basis of the embodiment 1, and its purpose is to provide a code-finding structure for the embodiment 1. The specific implementation method is as follows: it also includes a code-finding component, and the code-finding component includes a code-finding key 710 with a ratchet and a code-finding plate 720. The code-finding plate 720 is provided with a driving cam to drive the code-finding plate 720 to rotate.

[0085] Reference Figure 8 As shown, a code-finding groove 323.1 is provided on the character wheel assembly 320, and a ratchet on the code-finding key 710 can extend into the code-finding groove 323.1; the user drives the code-finding plate 720 to rotate the code-finding key 710, thereby turning the ratchet into the code-finding groove 323.1 or abutting against the character wheel assembly 320; at this time, the character wheel 322 is rotated, and the code-finding groove 323.1 also rotates. When the code-finding groove 323.1 rotates to the position where the ratchet abuts, the ratchet is stuck in the code-finding groove 323.1, and the character wheel 322 cannot continue to rotate.

[0086] In this embodiment, an operating block 721 is provided on the back of the code-finding plate 720 and extends out of the shell seat for human operation, and the code-finding plate 720 moves in a straight line. In order to convert the straight-line movement of the code-finding plate 720 into the rotation of the code-finding key 710, the end surface along the moving direction of the code-finding protrusion 722 is set as an inclined surface, and a shift block 711 is provided on the code-finding key 710 to contact the inclined surface and be driven by the inclined surface.

[0087] When the code-finding plate 720 moves, the inclined surface contacts the shift block 711, generating an inclined driving force on the shift block 711. The separation of the driving force pushes the shift block 711 downward. At the same time, the code-finding key 710 is hinged on the lock shell, so the code-finding key 710 rotates, causing the pawl to rotate toward the side of the character wheel assembly 320.

[0088] The structure of the code-finding key 710 and the installation method thereof with respect to the lock housing are consistent with those in the prior art and will not be described in detail herein.

[0089] To ensure the stability of the character wheel set 320, in this embodiment, the character wheel set 320 includes a character wheel core 321 and a character wheel 322 sleeved on the character wheel core 321. The character wheel core 321 is also limitedly sleeved with a character wheel 322 sleeve, and the code search groove 323.1 is located on the character wheel 322 sleeve.

[0090] Reference Fig. 9 As shown, the character wheel core 321 and the character wheel 322 are limitedly connected by convex points. At the same time, the inner circle of the character wheel 322 set is provided with a limit point 323.2, and the character wheel core 321 is provided with a notch 321.1. The character wheel 322 set and the character wheel core 321 are limitedly connected by the limit point 323.2 and the notch 321.1; when the character wheel 322 is turned, the character wheel core 321 and the character wheel 322 set are driven to rotate together; when changing the code, the character wheel core 321 and the character wheel 322 are separated, so that the character wheel 322 can rotate alone.

[0091] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
