Description

Technical Field

[0001] The utility model relates to the field of safe production, in particular to a safe lock. Background Art

[0002] According to their functions, safes are mainly divided into fireproof safes and anti-theft safes, anti-magnetic safes, fireproof and anti-magnetic safes, and fireproof and anti-theft safes, etc. Most of the safes on the market are the first two. In order to improve the safety performance of the safe door, the lock does not lock the door bolt, but locks the transmission component of the door bolt. After unlocking, the door bolt can be unlocked by controlling the transmission component through an external handle. In the existing safe door bolt transmission component, locking is only based on the structure transmitted by the lock. The locked state of the safe can be released by destroying the lock tongue of the lock, and the safety performance is poor.

[0003] After searching, the Chinese patent publication number CN218029608U is found, which discloses a safe lock structure. The safe lock structure drives the worm to rotate through a driving motor, and the worm drives the gear to rotate, so that the gear drives the movable rod to move horizontally through the threaded rod to realize the opening and closing of the lock, and the gear cannot be driven to rotate by the movement of the movable rod. This avoids the lock rod being artificially pried into the shell from the outside to open and close the lock, greatly improving the safety of the lock.

[0004] However, the above patent requires multiple transmissions such as worm gears and threaded rods to open and close the lock, which takes a long time and results in a slow opening or closing speed of the safe. Utility Model Content

[0005] The purpose of the utility model is to provide a safe lock in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A safe lock includes a housing. Two mounting handles are fixedly connected to the top of the housing. A movable plate is slidably connected to the inner bottom wall of the housing. One side of the movable plate is fixedly connected to a mounting plate, and the other end of the mounting plate is fixedly connected to a lock rod. The lock rod is slidably connected within the wall of the housing.

[0024] The present utility model will be further described below in conjunction with the accompanying drawings:

[0025] As Figures 1 - 5 shown, a safe lock includes a housing 1. Two mounting handles 101 are welded to the top of the housing 1. The housing 1 is mounted on different safes through the mounting handles 101. A movable plate 201 is slidably connected to the inner bottom wall of the housing 1. A chute is provided on the inner bottom wall of the housing 1. A slider 2011 is fixedly connected to the bottom of the movable plate 201. The slider 2011 is slidably connected in the chute. A mounting plate 202 is fixedly connected to one side of the movable plate 201. The other end of the mounting plate 202 is fixedly connected to a lock rod 203. The lock rod 203 is slidably connected within the wall of the housing 1. A circular hole is provided on the side wall of the housing 1. A sponge ring 4 is provided within the circular hole. Lubricating oil is soaked in the sponge ring 4. The lock rod 203 passes through between the sponge rings 4. The lock rod 203 is lubricated through the sponge ring 4 to prevent the lock rod 203 from rusting and getting stuck. An avoidance groove is provided on the top of the movable plate 201. A mounting rod 301 is located within the avoidance groove.

[0026] A mounting rod 301 is fixedly connected to the inner bottom wall of the housing 1. A turntable 302 is rotatably connected to the mounting rod 301. A first driving rod 303 and a second driving rod 304 are provided above the turntable 302. The first driving rod 303 and the second driving rod 304 are long and straight thin plate shapes to prevent jamming. The first driving rod 303 and the second driving rod 304 are arranged vertically and staggered. Pressing handles 305 are fixedly connected to the mutually remote ends of the first driving rod 303 and the second driving rod 304. The pressing handles 305 are slidably connected within the wall of the housing 1.

[0027] A power assembly is provided between the first driving rod 303 and the second driving rod 304 and the turntable 302. The power assembly is used to drive the turntable 302 to rotate when the first driving rod 303 and the second driving rod 304 move relatively. The power assembly includes a first fixed column 306 and a second fixed column 307 inserted into the top of the turntable 302. The first fixed column 306 is respectively located on both sides of the first driving rod 303 and the second driving rod 304. The second fixed column 307 is located on the side of the first fixed column 306 close to the lock rod 203. Driving rings 308 are fixedly connected to the side walls of the first driving rod 303 and the second driving rod 304. The first fixed column 306 is located within the driving ring 308 fixedly connected to the first driving rod 303. The second fixed column 307 is located within the driving ring 308 fixedly connected to the second driving rod 304.

[0028] A driving component is arranged between the turntable 302 and the movable plate 201. The driving component is used to drive the movable plate 201 to move when the turntable 302 rotates. The driving component includes a limiting rod 309 inserted at the bottom of the turntable 302. The limiting rod 309 is eccentrically arranged. A limiting groove 310 is formed at the top of the movable plate 201. The limiting groove 310 is parallel to the mounting plate 202. The limiting rod 309 is slidably connected in the limiting groove 310.

[0029] Long strip-shaped through holes are formed in both the first driving rod 303 and the second driving rod 304. The mounting rod 301 passes through the through holes. Through the cooperation of the mounting rod 301 and the through holes, the moving distance of the first driving rod 303 and the second driving rod 304 is limited.

[0030] Working principle: When pressing the two pressing handles 305 inward or pulling the two pressing handles 305 outward, the pressing handles 305 drive the first driving rod 303 and the second driving rod 304 to move in opposite directions. The moving distance of the first driving rod 303 and the second driving rod 304 is limited by the mounting rod 301. The movement of the first driving rod 303 and the second driving rod 304 will drive the driving ring 308 to move. Since the first fixing column 306 and the second fixing column 307 are located inside the driving ring 308, when the two driving rings 308 move, the first fixing column 306 and the second fixing column 307 will drive the turntable 302 to rotate. The rotation of the turntable 302 will drive the limiting rod 309 to rotate. Restricted by the limiting groove 310, when the limiting rod 309 rotates, it will drive the movable plate 201 to drive the mounting plate 202 and the locking rod 203 to move, thereby realizing the opening and closing of the lock. The opening and closing of the lock can be realized by using the short-distance movement time of the pressing handle 305. It is not only labor-saving but also can avoid jamming, improving the speed of opening or closing the safe. The locking rod 203 is lubricated by the sponge ring 4 to avoid rusting of the locking rod 203.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
