Description

Technical Field

[0001] This utility model relates to a lock, and more particularly to a concealed beam lock that incorporates a mechanical combination. Background Technology

[0002] Currently, most door locks with lock noses use locks where the lock beam is mostly exposed outside the lock body. The lock beam of this type of lock is easily pried or sawed, resulting in poor security. Therefore, this type of lock has been largely phased out in places with high security requirements, and has been replaced by concealed locks with a short, thick straight beam hidden inside the lock body, offering better anti-pry performance (such as the structure shown in application number 202323220595.5 for a metal concealed lock). In this type of concealed lock, a key is used to open the lock cylinder, releasing the lock bolt from the lock beam. The bolt then disengages from the locking groove, and the outer end of the lock beam is pulled outwards until the spring pin pops out and enters the limiting groove, fully opening the metal concealed lock.

[0003] However, in some special situations, the concealed beam lock with the above structure is not suitable, such as in vaults or banks, or in some places with high security levels, where multiple people need to unlock the lock at the same time to prevent risks. Because the applicant has modified the structure of the aforementioned concealed beam lock and combined it with an existing mechanical combination lock on the market (name: a multi-purpose rotary combination lock, application number: 202422805299X, whose working principle is: when the correct combination is entered on the dial ring, the protrusion of the lock bar will be aligned with the unlocking notch on the lock plate, thus allowing the lock bar to move. The return 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. The lock bar will push the lock rod to rotate, causing the bolt to extend from the second through hole, thereby unlocking. When locking, simply rotating the dial ring will cause the outer arc wall of the lock plate to press against the protrusion, which will cause the lock bar to move in the opposite direction. The lock bar will pull the lock rod to rotate, causing the bolt to retract from the second through hole, thus locking.) to form a double-opening concealed beam lock. This allows one person to keep the key and another person to keep the combination. Both people need to be present at the same time to unlock, using the key and combination to unlock, thereby improving security and reducing risk. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a hidden beam lock that combines mechanical password.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A concealed beam lock incorporating a mechanical combination includes a lock body, a lock beam disposed within the lock body, a key lock cylinder, and a mechanical combination core. The mechanical combination core includes a rotatable lock rod. The key lock cylinder is characterized by having a paddle; the lock body contains a first elastic element, a second elastic element, and a first lever and a second lever hinged together; the first lever has a locking block; the second lever has a locking block; and the lock beam has a locking groove. The first lever can rotate under the action of the lock rod, causing the first locking block to disengage from the locking groove; the second lever can rotate under the action of the paddle, causing the second locking block to disengage from the locking groove; the first elastic element can push the first lever to rotate, causing the first locking block to engage in the locking groove; and the second elastic element can push the second lever to rotate, causing the second locking block to engage in the locking groove.

[0007] The lock body includes a base and a top cover.

[0008] The base is provided with a beam hole and a bottom hole 1 that communicates with the beam hole. Both the first and second locking blocks are located in the bottom hole 1, and when locked, the locking groove can be located in the bottom hole 1 and engage with the first and second locking blocks.

[0009] The base is provided with a second bottom hole, and a spindle is provided in the second bottom hole. Both lever one and lever two are provided with shaft holes that are hinged to the spindle.

[0010] The lever is provided with an extension plate and a protrusion perpendicular to the extension plate. The locking rod can push the protrusion to make the lever rotate.

[0011] The lever two is provided with an end rod, and the paddle can push the end rod to make the lever two rotate. The end rod is located in the bottom hole two.

[0012] The first lever has a mounting hole at its end. The first elastic element is a spring. The first elastic element is installed in the mounting hole, with one end of the first elastic element abutting against the mounting hole and the other end abutting against the bottom hole. The second lever has a mounting hole at its end. The second elastic element is a spring. The second elastic element is installed in the mounting hole, with one end of the second elastic element abutting against the mounting hole and the other end abutting against the bottom hole.

[0013] Both lever one and lever two include a protruding post at one end and a protruding plate at the other end, and the locking block one and the locking block two are disposed on the corresponding protruding plates.

[0014] A clutch mechanism is provided between lever one and lever two, so that lever one and lever two can rotate separately or rotate as a whole.

[0015] The clutch mechanism includes a locking screw, and lever one and lever two can be fixed together by the locking screw.

[0016] The beneficial effects of this utility model are as follows: This utility model installs a mechanical combination lock core into the lock body, and hinges a lever one and a lever two within the lock body. Lever one has a locking block one; lever two has a locking block two, and a slot is provided on the lock beam. The lever one is rotated by the locking rod of the mechanical combination lock core, and lever two is rotated by the paddle of the key lock core. This allows locking blocks one and two to disengage from the slot simultaneously or sequentially, thus unlocking the lock. This combines a concealed beam lock with a mechanical combination lock, allowing one person to keep the key while another person keeps the combination. Both people need to be present at the same time to unlock the lock, using both the key and the combination, thereby improving security and reducing risk. Attached Figure Description

[0032] Reference Figures 1 to 7This utility model discloses a concealed beam lock incorporating a mechanical combination, comprising a lock body 1, a lock beam 2 disposed within the lock body 1, a key lock cylinder 3, and a mechanical combination cylinder 4. The lock body 1 includes a base 5 and a top cover 6. The mechanical combination cylinder 4 includes a rotatable locking rod 28. The key lock cylinder 3 is provided with a lever 7. Both the mechanical combination cylinder 4 and the key lock cylinder 3 are installed in the lock body 1 using existing technology via screws, therefore their specific structures are not detailed. The top cover 6 has a combination hole, and the lever ring 8 of the mechanical combination cylinder 4 protrudes from the top cover 6 through the combination hole. The lock body 1 is provided with an elastic element 1 9 and an elastic element 2 1. 0. The lock beam 2 is hinged with lever 11 and lever 22. Lever 11 is provided with a locking block 13, and lever 22 is provided with a locking block 24. The locking beam 2 is provided with a locking groove 15. Lever 11 can rotate under the action of locking rod 28, causing locking block 13 to disengage from the locking groove 15. Lever 22 can rotate under the action of lever 7, causing locking block 24 to disengage from the locking groove 15. Elastic element 19 can push lever 11 to rotate, causing locking block 13 to engage in the locking groove 15. Elastic element 20 can push lever 22 to rotate, causing locking block 24 to engage in the locking groove 15.

[0033] The principle of the above structure is that when the correct password is entered into the dial ring 8, the lock bar 27 will move and push the lock rod 28 to rotate, causing the push lever 11 to rotate, thereby causing the locking block 13 to disengage from the slot 15. At this time, the lock cannot be unlocked yet. The key lock cylinder 3 needs to be inserted to make the key lock cylinder 3 rotate. The key lock cylinder 3 drives the lever 7 to rotate. When the lever 7 rotates, it pushes the lever 12 to rotate, thereby causing the locking block 14 to disengage from the slot 15. At this time, the user can pull out the lock beam 2 to unlock. If the lock is to be locked, the lock beam 2 is inserted first, and then the dial ring 8 is rotated. The lock bar 27 will be reset. At this time, the elastic element 9 can push the lever 11 to rotate, causing the locking block 13 to engage in the slot 15. Then the key lock cylinder 3 is rotated to reset. The elastic element 10 can push the lever 12 to rotate, causing the locking block 14 to engage in the slot 15. Of course, the above can also be used to unlock with the key first and then unlock 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 first locking block 13 and the second locking block 14 are both located in the bottom hole 17. When locked, the slot 15 can be located in the bottom hole 17 and engage with the first locking block 13 and the second locking block 14. The base 5 is provided with a bottom hole 18, and a spindle 19 is provided in the bottom hole 18. The first lever 11 and the second lever 12 are both provided with shaft holes that are hinged to the spindle 19. When the upper cover 6 and the base 5 are locked together with screws, the upper cover 6 can prevent the first lever 11 and the second lever 12 from coming out of the shaft holes.

[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 make the lever 11 rotate. Due to the limitation of the position and structure of the mechanical key 4, the lever 11 needs to be provided with an extension plate 20 and a protrusion 21 in order to be pushed by the locking rod 28.

[0036] The lever 12 is provided with an end rod 22. The paddle 7 can push the end rod 22 to make the lever 12 rotate. The end rod 22 is located in the bottom hole 18. Due to the limitation of 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 lever 11 is provided with mounting hole 1, the elastic element 9 is a spring, the elastic element 9 is installed in mounting hole 1, and one end of the elastic element 9 abuts against mounting hole 1, while the other end of the elastic element 9 abuts against bottom hole 17; the end of lever 12 is provided with mounting hole 2, the elastic element 2 10 is a spring, the elastic element 2 10 is installed in mounting hole 2, and one end of the elastic element 2 10 abuts against mounting hole 2, while the other end of the elastic element 2 10 abuts against bottom hole 17. The spring is installed through the above structure.

[0038] As shown in the figure, both lever 11 and lever 12 include a protruding post 23 at one end, an end rod 22 on the protruding post 23 of lever 12, and a protruding plate 24 at the other end. Lever 11 and lever 12 are U-shaped. The locking block 13 and the locking block 24 are disposed on the corresponding protruding plate 24. The above structure makes full use of the internal space of the lock body 1 and avoids the restriction of the recess 25.

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

[0040] The base 5 of the concealed beam lock has a recessed groove 25 to accommodate the lock lug on the door. To facilitate the adjustment of the clutch mechanism, a tool hole (not shown in the figure) is provided at the bottom of the recessed groove 25. Lever 11 has a screw hole and lever 22 has a through hole 26. The tool hole is directly opposite the screw hole and the through hole 26. The locking screw can be inserted into the through hole 26 through the tool hole and cooperate with the screw hole, thereby locking lever 11 and lever 22 into one unit. When unlocking with a key or combination, whether the lock rod 28 pushes lever 11 or the lever 7 pushes lever 22, lever 11 and lever 22 can be rotated simultaneously, thereby disengaging the locking blocks 13 and 24 from the locking slot 15. This allows for single-key or combination unlocking. To achieve double-key and combination unlocking, simply 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 much space.

[0041] The above provides a detailed description of a concealed beam lock incorporating a mechanical combination lock, as provided in the embodiments of this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
