Description

Technical Field

[0001] The invention relates to a lock, in particular to a concealed beam lock capable of being opened in two ways with a password key. Background Art

[0002] Currently, door locks with lock noses mostly use locks in which the lock beam is mostly exposed outside the lock body. The lock beam of this type of door lock is easy to pry and saw, and has poor security performance. Therefore, this type of door lock has been basically eliminated in some places with high security performance requirements. It has been replaced with a concealed beam lock with a short, thick straight beam hidden inside the lock body, which has better anti-pry performance (such as the structure shown in the metal concealed beam lock application No. 202323220595.5. The concealed beam lock with this structure uses a key to open the lock cylinder, releasing the lock tongue of the lock cylinder from locking the lock beam. At this time, the lock tongue disengages from the locking groove, pulls the outer end of the lock beam outward, and the spring pin pops out and enters the limit groove, and the metal concealed beam lock is fully opened).

[0003] However, in some special occasions, the hidden beam lock of the above structure is not applicable, such as in a vault or a bank, or some places with a high level of confidentiality, where multiple people are required to unlock the door at the same time to prevent risks. Because the applicant has changed the structure of the above-mentioned hidden beam lock, and combined it with the existing mechanical password lock on the market (name: a multi-purpose rotary knob password lock, application number: 202422805299X, its working principle is: when the correct password is entered into the dial ring, the protrusion of the lock bar will be opposite to the unlocking notch on the lock plate so that the lock bar has space to move, and the reset spring can push the lock bar to move, and the protrusion of the lock bar will be embedded in the unlocking notch on the lock plate, and the lock bar will push the lock rod to rotate and the lock tongue will extend from the second through hole, thereby unlocking; when locking, just rotate the dial ring to make the outer arc wall of the lock plate squeeze the protrusion to make the lock bar move in the opposite direction, and the lock bar will pull the lock rod to rotate and retract the lock tongue from the second through hole to achieve locking.) to form a double-opening hidden beam lock, so that one person can keep the key and the other person can keep the password. Two people need to be present at the same time to unlock, and use the key and password to unlock, thereby improving security and reducing risks. Summary of the Invention

The embodiments of the present disclosure may be performed independently of each other, or may be performed together in a mutually dependent relationship.

[0032] Reference Figures 1 to 7The present invention discloses a concealed beam lock capable of double opening with a password key, comprising a lock body 1, a lock beam 2 arranged in the lock body 1, a key lock core 3, and a mechanical password core 4. The lock body 1 comprises a base 5 and an upper cover 6. The mechanical password core 4 comprises a rotatable lock rod 28. The key lock core 3 is provided with a paddle 7. The mechanical password core 4 and the key lock core 3 are both installed in the lock body 1 by screws according to the prior art, so the specific structure is not described in detail. The upper cover 6 is provided with a password hole, and the dial wheel 8 of the mechanical password core 4 protrudes from the upper cover 6 through the password hole. The lock body 1 is provided with an elastic member 1 9 and an elastic member 2 1. 0, and is hinged with a lever 11 and a lever 2 12, the lever 11 is provided with a card block 13, the lever 2 12 is provided with a card block 2 14, and the lock beam 2 is provided with a card slot 15, the lever 11 can be rotated under the toggle of the lock rod 28 to make the card block 13 disengage from the card slot 15; the lever 2 12 can be rotated under the toggle of the paddle 7 to make the card block 2 14 disengage from the card slot 15, the elastic member 1 9 can push the lever 11 to rotate to make the card block 13 engage in the card slot 15; the elastic member 2 10 can push the lever 2 12 to rotate to make the card block 2 14 engage in the card slot 15.

[0033] The principle of the above structure is that when the correct password is input into the dial ring 8, the lock bar 27 will move and push the lock rod 28 to rotate, so that the push lever 11 rotates, thereby driving the card block 13 to disengage from the card slot 15; at this time, the lock cannot be unlocked, and the key needs to be inserted into the key lock cylinder 3 to rotate the key lock cylinder 3, and the key lock cylinder 3 drives the paddle 7 to rotate. When the paddle 7 rotates, it pushes the lever 2 12 to rotate, thereby driving the card block 2 14 to disengage from the card slot 15, at this time, the user can pull out the lock beam 2 to unlock. If you want to lock, first insert the lock beam 2, and then rotate the dial ring 8, the lock bar 27 will reset, and at this time the elastic member 1 9 can push the lever 1 11 to rotate and make the card block 13 snap into the card slot 15; then make the key lock cylinder 3 rotate and reset, and the elastic member 2 10 can push the lever 2 12 to rotate and make the card block 2 snap into the card slot 15. Of course, the above can also be done with the key first and then with the password.

[0034] As shown in the figure, the base 5 is provided with a beam hole 16 and a bottom hole 17 that passes through the beam hole 16. The clamping block 13 and the clamping block 2 14 are both located in the bottom hole 17, and when locked, the clamping slot 15 can be located in the bottom hole 17 and clamped with the clamping block 13 and the clamping block 2 14. The base 5 is provided with a bottom hole 2 18, and the bottom hole 2 18 is provided with a core shaft 19. The lever 1 11 and the lever 2 12 are both provided with an axial hole hinged to the core shaft 19. When the upper cover 6 and the base 5 are tightened by screws, the upper cover 6 can prevent the lever 11 and the lever 2 12 from escaping from the axial hole.

[0035] As shown in the figure, the lever 11 is provided with an extension plate 20 and a protrusion 21 perpendicular to the extension plate 20. The locking rod 28 can push the protrusion 21 to rotate the lever 11. Due to the position and structure of the mechanical code core 4, the lever 11 needs to be provided with the extension plate 20 and the protrusion 21 in order to be pushed by the locking rod 28.

[0036] The lever 12 is provided with an end rod 22, and the paddle 7 can push the end rod 22 to rotate the lever 12. The end rod 22 is located in the bottom hole 18. Due to the position and structure of the key lock cylinder 3, the lever 12 needs to be provided with an end rod 22 in order to be pushed by the paddle 7.

[0037] As shown in the figure, the end of the lever 11 is provided with a mounting hole 1, the elastic part 19 is a spring, the elastic part 19 is installed in the mounting hole 1, and one end of the elastic part 19 is against the mounting hole 1, and the other end of the elastic part 19 is against the bottom hole 17; the end of the lever 2 12 is provided with a mounting hole 2, the elastic part 2 10 is a spring, the elastic part 2 10 is installed in the mounting hole 2, and one end of the elastic part 2 10 is against the mounting hole 2, and the other end of the elastic part 2 10 is against the bottom hole 17. The installation of the spring is achieved through the above structure.

[0038] As shown in the figure, the lever 11 and the lever 2 12 each include a protrusion 23 provided at one end, an end rod 22 provided on the protrusion 23 of the lever 2 12, and a protruding plate 24 provided at the other end. The lever 11 and the lever 2 12 are concave in shape, and the clamping block 13 and the clamping block 2 14 are provided on the corresponding protruding plates 24. The above structure makes full use of the space inside the lock body 1 and avoids the limitation of the sinking groove 25.

[0039] As shown in the figure, a clutch mechanism is provided between the lever 11 and the lever 2 12 so that the lever 11 and the lever 2 12 can rotate separately or as a whole, thereby realizing single opening by key or password, or double opening by key and password; the clutch mechanism includes a locking screw (not shown in the figure), and the lever 11 and the lever 2 12 can be fixed together by the locking screw.

[0040] The base 5 of the hidden beam lock has a recess 25 for accommodating the lock nose on the door. In order to facilitate the adjustment of the clutch mechanism, the present application provides a tool hole (not shown in the figure) at the bottom of the recess 25, and a screw hole is provided on the lever 11, and a through hole 26 is provided on the lever 2 12. The tool hole is opposite to the screw hole and the through hole 26, and the locking screw can be inserted into the through hole 26 through the tool hole and cooperate with the screw hole, thereby locking the lever 11 and the lever 2 12 as a whole. When the lock is unlocked with a key or a password, whether the locking rod 28 pushes the lever 11 or the paddle 7 pushes the lever 2 12, both the lever 11 and the lever 2 12 can be rotated at the same time, so that the card block 13 and the card block 2 14 are both out of the card slot 15, so that either the key or the password can be achieved. If both the key and the password are to be achieved, it is only necessary to use a tool to loosen and remove the locking screw. The tool is generally a screwdriver with a magnetic head. The above structure is simple and does not take up space.

[0041] The above is a detailed introduction to a concealed beam lock that can be opened with a password key in two ways provided in an embodiment of the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
