Description

Technical Field

[0001] This utility model relates to the field of safe technology, and in particular to a novel safe. Background Technology

[0002] In existing safe latch unlocking mechanisms, the pure linkage transmission scheme is widely used. This scheme typically involves turning the handle directly to drive the linkage, which in turn drives the latch to complete the insertion and extraction action, thus opening and closing the lock. However, pure linkage transmission has the following drawbacks: 1. Linkage transmission is mostly a flexible hinge structure, resulting in large transmission gaps, low motion accuracy, and after long-term use, it is prone to transmission deviation due to stress deformation, leading to problems such as latch jamming and misalignment with the latch hole, affecting the normal opening and closing of the lock; 2. Linkage transmission has low efficiency, with large losses and uneven force distribution during force transmission, high operating resistance when turning the handle, and a tendency to experience dead points, resulting in poor ease of use. Summary of the Invention

[0003] The purpose of this invention is to provide a new type of safe to solve the problems mentioned in the background section.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A novel safe includes a first cabinet body, a door shell hinged to the first cabinet body, a door panel fixedly connected to one outer wall of the door shell, a first fixing rod fixedly connected inside the door shell, a rack slidably connected to the top of the first fixing rod, a gear meshing with the rack, a connecting shaft fixedly connected to the gear, a handle fixedly connected to the connecting shaft, and the handle hinged to the door shell, a connecting plate fixedly connected to the rack, a connecting rod fixedly connected to the connecting plate, and the connecting rod slidably connected to the door panel, a plurality of pins fixedly connected to the connecting rod, and a socket fixedly connected to the first cabinet body at the position corresponding to the pins, the socket having a socket hole.

[0005] Preferably, a mounting base is fixed through the door panel at the position corresponding to the socket, and a through hole is opened on the mounting base at the position corresponding to the plug hole. A sleeve is sleeved on the pin, and the sleeve is conductively fixed on the mounting base.

[0006] Preferably, a second fixing rod is fixedly connected inside the door shell and fixedly connected to the door panel. A sliding groove is provided on the second fixing rod, and the connecting rod is slidably connected in the sliding groove.

[0007] Preferably, a second cabinet is fixedly connected inside the first cabinet.

[0008] Preferably, limit posts are provided on both sides of the rack, and the limit posts are fixedly connected to the first fixed rod.

[0009] Preferably, a combination lock is fixedly connected inside the door shell, a combination dial is fixedly connected to the door shell, the combination dial is driven to the input end of the combination lock, a lock tongue is driven to the output end of the combination lock, a bent plate is fixedly connected to the connecting plate, and a through groove is opened on the bent plate at the position corresponding to the lock tongue.

[0010] Preferably, a hinge is fixedly connected to the door shell, and the hinge is fixedly connected to the first cabinet.

[0011] This utility model provides a novel safe with the following advantages: This utility model uses a gear to drive a rack, which in turn drives a connecting rod, thereby controlling the insertion and removal of the pin on the connecting rod. Compared to existing pure linkage transmission structures, this results in smaller transmission gaps and higher motion precision. It avoids the pin jamming and alignment deviation problems caused by deformation in pure linkage transmissions, ensuring the pin smoothly and accurately disengages or inserts into the socket. Furthermore, the gear and rack transmission is more efficient than pure linkage transmission, with more direct and uniform force transmission, making operation easier when turning the handle and effectively reducing the operating resistance and dead-point force problems of pure linkage transmissions. Simultaneously, the combined structure of the gear and rack is more stable, has better resistance to deformation than pure linkages, exhibits less transmission precision decay after long-term use, and has a longer service life. Overall, the transmission reliability and user experience are significantly improved compared to existing pure linkage transmission solutions. Attached Figure Description

A socket 11 is fixedly connected at the position of the cabinet. The socket 11 has a socket hole 12. The door shell 2 and the door panel 22 constitute the cabinet door. The first fixing rod 23 is used to support the rack 25. The handle 28 is used to facilitate the rotation of the connecting shaft 27. The connecting shaft 27 is used to drive the gear 26. The gear 26 is used to drive the rack 25. The rack 25 drives the connecting rod 215 through the connecting plate 29, thereby driving the pin 216 on the connecting rod 215. The pin 216 cooperates with the socket hole 12 on the socket 11 to lock the cabinet door onto the first cabinet body 1. A mounting base 218 is fixedly fixed through the door panel 22 at the position corresponding to the socket 11. The mounting base 218 has a through hole 219 at the position corresponding to the socket hole 12. A sleeve 217 is sleeved on the pin 216. 7. A through hole 219 is fixed to the mounting base 218, which is used to accommodate the socket 11. The through hole 219 is used to avoid the pin 216. The sleeve 217 is used to guide the pin 216. A second fixing rod 220 is fixedly connected inside the door shell 2 and is fixedly connected to the door panel 22. A sliding groove 221 is provided on the second fixing rod 220, and the connecting rod 215 is slidably connected in the sliding groove 221. The second fixing rod 220 is used to connect the door shell 2 and the door panel 22, and the sliding groove 221 is used to accommodate the connecting rod 215. A second cabinet 3 is fixedly connected inside the first cabinet 1. The second cabinet 3 is used to classify and store items. Limiting posts 24 are provided on both sides of the rack 25, and the limiting posts 24 are fixedly connected to the first fixing rod 23. Position post 24 is used to limit the rack 25; a combination lock 212 is fixedly connected inside the door shell 2, and a combination disc 214 is fixedly connected to the door shell 2. The combination disc 214 is driven to the input end of the combination lock 212, and a lock tongue 213 is driven to the output end of the combination lock 212. A bending plate 210 is fixedly connected to the connecting plate 29. A through groove 211 is opened on the bending plate 210 at the position corresponding to the lock tongue 213. The combination disc 214 is used to input the password.

[0017] Working principle: When using this utility model, after entering the correct password by turning the combination dial 214, the combination lock 212 can be unlocked, allowing the bolt 213 to disengage from the through groove 211, thereby releasing the lock on the folding plate 210. At this time, the handle 28 can be turned, which drives the gear 26 via the connecting shaft 27. The gear 26 drives the rack 25 to slide along the first fixed rod 23. The rack 25 drives the connecting rod 215 via the connecting plate 29. The connecting rod 215 slides in the groove 221 on the second fixed rod 220, and the pin 216 on the connecting rod 215 slides in the sleeve 217 accordingly. When the slide reaches the end of the slide groove 221, the pin 216 disengages from the socket 12, thereby releasing the lock between the mounting base 218 and the socket 11. The handle 28 can be pulled outward to open the cabinet door. The door shell 2 and the door panel 22 constitute the cabinet door. The hinge 21 is used to achieve the hinge between the first cabinet body 1 and the cabinet door. The limiting post 24 is used to limit the rack 25. The through hole 219 is used to avoid the pin 216. The second cabinet body 3 is used to classify and store items. The combination dial 214 and the combination lock 212 are common knowledge in the field, so their principles and structures will not be described in detail.
