[0002] Currently, most door locks with key bolts have the lock beam mostly exposed outside the lock body. The lock beam of this type of lock is easy to pry and saw, 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 Therefore, this type of lock has been largely phased out in places with high security requirements, and has been replaced by concealed-beam locks with a short, thick, straight beam hidden inside the lock body, offering better anti-pry performance. However, existing concealed-beam locks still experience some problems in actual use.

[0003] For example, application number CN202323220595.5 discloses a metal concealed beam lock, including a lock body, a lock cylinder, and a lock beam. The lock body is a one-piece metal block with a core hole and a beam channel communicating with the core hole. The lock cylinder is installed in the core hole, and the lock beam is slidably installed in the beam channel from one side of the lock body. The lock tongue of the lock cylinder is movably connected to the lock beam. A pin hole is provided in the beam channel, and a spring pin is slidably installed in the pin hole. The spring pin is movably connected to the lock beam. This lock is convenient to use. In the case of existing concealed beam locks, the interlocking interface used for unlocking is mostly exposed. When theft occurs, thieves can easily insert tools into the interlocking interface to open the lock, which is not conducive to use.

[0004] To address the aforementioned problems, a concealed beam lock with an anti-vandalism mechanism is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a concealed beam lock with an anti-vandalism mechanism. By using this device, the problem of existing concealed beam locks being inconvenient to use is solved, as the unlocking interface is mostly exposed. In the event of theft, thieves can easily insert tools into the interface to open the lock.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concealed beam lock with an anti-vandalism mechanism, comprising a left lock body and a right lock body disposed on one side of the left lock body. A transmission knob is rotatably connected to the bottom of the left lock body, and a limit groove is formed at the bottom of the transmission knob.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0027] Combination Figures 1-4 A concealed beam lock with an anti-vandalism mechanism includes a left lock body 1 and a right lock body 2 located on one side of the left lock body 1. A transmission knob 11 is rotatably connected to the bottom of the left lock body 1. A limit groove 111 is formed at the bottom of the transmission knob 11. A knob 12 is detachably provided on the outside of the transmission knob 11. A lock cylinder 13 is rotatably connected to the inside of the left lock body 1. An arc block 131 is fixedly connected to one end of the lock cylinder 13. A connecting plate 21 is fixedly connected to the inside of the right lock body 2. A fixing block 22 is slidably connected to the connecting plate 21. The right lock body 2 is provided with a fixing mechanism, which serves to fix the arc block 131.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] To address the problem that in existing concealed beam locks, the unlocking interface is mostly exposed, making it easy for thieves to insert tools into the interface and open the lock in case of theft, which is inconvenient to use, this embodiment discloses the following technical solution, specifically as follows: Figures 1-4As shown, a rotating ring 112 is rotatably connected to the outer side of the transmission knob 11. The rotating ring 112 is slidably engaged with the knob 12. A limit block 121 is fixedly connected inside the knob 12. The limit block 121 is slidably engaged with the limit groove 111. A positive and negative threaded rod 113 is fixedly connected to one end of the transmission knob 11. Protective plates 114 are threaded to both ends of the positive and negative threaded rod 113. A fixing groove 132 is opened on one side of the arc block 131. The protective plate 114 is slidably connected to the inside of the left lock body 1. An arc groove 211 is opened on the connecting plate 21. A return spring 221 is fixedly connected to one end of the fixing block 22. One end of the return spring 221 is fixedly connected to the inside of the connecting plate 21. When it is necessary to protect the lock cylinder 13 on one side of the left lock body 1 during use, the knob 12 can be turned. The knob is fitted onto the outside of the rotating ring 112, causing the limiting block 121 inside the knob 12 to contact the limiting groove 111. Rotating the knob 12 causes the transmission knob 11 to rotate, which in turn causes the positive and negative threaded rod 113 to rotate. The positive and negative threaded rod 113 drives the two sets of protective plates 114 to move. At this time, the two sets of protective plates 114 are in contact, which can close one side of the lock cylinder 13. When the knob 12 is removed, in the event of theft, it will be difficult for the thief to find a tool that fits the limiting block 121. Furthermore, due to the self-locking function of the positive and negative threaded rod 113, conventional pry bars cannot move the protective plates 114, which significantly increases the difficulty of separating the left lock body 1 and the right lock body 2. This achieves the effect of protecting one side of the lock cylinder 13 and improves the security factor.

[0031] To address the issue that existing concealed beam locks often rely on a single locking structure, which can lead to the locking structure detaching during use and affecting usability, this embodiment also discloses the following solution: The fixing mechanism includes a magnet 23 fixedly connected to the top of the fixing block 22. A magnet 231 is detachably mounted on one side of the right lock body 2. Magnet 231 has opposite magnetic properties to magnet 23. When the user needs to lock both the left lock body 1 and the right lock body 2, the lock cylinder 13 is turned with a key. The lock cylinder 13 rotates the arc block 131, causing it to move into the right lock body 2 and into the arc groove 211 on the connecting plate 21. Inside, due to the rounded corners of the arc block 131 and the fixed block 22, the fixed groove 132 can rotate. Under the action of the return spring 221, the fixed block 22 moves into the interior of the fixed groove 132, thus fixing the arc block 131 and preventing it from moving out of the arc groove 211. When unlocking is required, the second magnet 231 can be used. The second magnet 231 is attached to one side of the right lock body 2. Under the action of magnetic force, the fixed block 22 moves and comes out of the interior of the fixed groove 132. At this time, the lock cylinder 13 can be rotated to unlock, thus achieving an additional fixing effect on the arc block 131 and improving the convenience of use.

[0032] Example 2:

[0033] This embodiment discloses another fixing method, which differs from Embodiment 1 and can improve the overall connection stability of the device. Please refer to the following for details. Figure 5 The fixing mechanism includes a locking block 24 fixedly connected to the top of the fixing block 22. A movable block 241 is detachably provided on the top of the right lock body 2. A contact rod 242 is fixedly connected to the bottom of the movable block 241. The contact rod 242 slides with the locking block 24. When unlocking is required, the contact rod 242 at the bottom of the movable block 241 can be extended into the interior of the right lock body 2. The contact rod 242 engages with the locking block 24, thereby moving the fixing block 22. After the fixing block 22 is moved out of the interior of the fixing groove 132, the lock cylinder 13 can be rotated to unlock.

[0034] Example 3:

[0035] This embodiment discloses another fixing method, which differs from Embodiments 1 and 2, and can improve the connection stability of the overall device. Please refer to the following for details. Figure 6The fixing mechanism includes a knob 25 rotatably connected to one side of the right lock body 2. A gear 251 is fixedly connected to the bottom of the knob 25, and a transmission rack 252 is meshed with one side of the gear 251. The transmission rack 252 is fixedly connected to the fixing block 22. When an unlocking operation is required, the knob 25 located on one side of the right lock body 2 can be rotated. The knob 25 drives the gear 251 to rotate, which in turn causes the transmission rack 252 to move. The transmission rack 252 drives the fixing block 22 to move, which in turn causes the fixing block 22 to move out of the fixing groove 132. Then the lock cylinder 13 can be rotated, so that the left lock body 1 and the right lock body 2 are separated, and the unlocking operation is realized.
