Description

Technical Field

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

[0002] A safe is a special container whose main function is to prevent theft through a complex combination of passwords and locking mechanisms. With the development of electronic locks, most existing safes are now electronic. Their working principle is that after the correct password is entered, the solenoid valve is energized, causing the armature to retract and releasing the mechanical limit on the bolt support. Then, rotating the handle drives the lever to rotate, which in turn moves the bolt support, causing the bolt to retract and unlocking the safe. Traditional levers consist of a dial and a pin. The dial is connected to the handle, and the pin is eccentrically fixed to one side of the dial, driving the bolt support to move. During unlocking, the lever needs to withstand a significant force. The dial and pin are usually connected by welding, riveting, or screws. Welding increases the connection strength of the lever, thus improving its load-bearing capacity, but the process is complex, requiring weld inspection after welding, resulting in high production costs. Riveting or screw connections have low structural strength, are prone to breakage and separation, and have poor load-bearing capacity. Therefore, improvements are necessary. Utility Model Content

Detailed Implementation

[0025] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0026] A simplified safe with a lever 34, such as Figures 1 to 6As shown, the device includes a cabinet body 1, a cabinet door 2, and a lock body 3. The cabinet door 2 is hinged to one side of the cabinet body 1. The lock body 3 is fixedly installed on the cabinet door 2. The lock body 3 includes a handle 31, a latch assembly 32, an electronic lock assembly 33, and a lever 34. The handle 31 is rotatably installed on the outside of the cabinet door 2. The handle 31 is connected to the lever 34, and the lever 34 is connected to the latch assembly 32. The electronic lock assembly 33 is in a limiting fit with the latch assembly 32. The lever 34 includes a connecting plate 341 and a lever plate 342. The lever plate 342 is formed on the outer edge of the connecting plate 341 to form an integral structure of the lever 34. The lever plate 342 is bent toward the latch assembly 32. The latch assembly 32 is provided with an unlocking groove 321. The outer end of the lever plate 342 is inserted into the unlocking groove 321 and slides with the unlocking groove 321. The connecting plate 341 is fixedly connected to the handle 31. Traditional paddles 34 employ a split structure, with the paddle lever connected to the dial via welding, riveting, or screwing. This results in a complex structure, cumbersome manufacturing process, high production costs, low structural strength, susceptibility to breakage, and poor reliability and stability. In contrast, the paddle plate 342 of this invention is formed on the connecting disc 341, creating an integrated paddle structure. This improves the structural strength of the paddle 34, prevents breakage, enhances load-bearing capacity, extends service life, and improves reliability and stability. During the production of the paddle 34, the sheet metal is stamped to obtain the paddle 34, and then the paddle plate 342 is bent using a bending process to complete the manufacturing. This simplifies the production process, eliminates the need for secondary assembly, improves production efficiency, and reduces production costs.

[0027] Specifically, the lever 342 includes a lever portion 3421 and a connecting reinforcement portion 3422. The first side of the connecting reinforcement portion 3422 is formed on the connecting plate 341, and the second side of the connecting reinforcement portion 3422 is integrally formed with the lever portion 3421. The lever portion 3421 inserts into and slides with the unlocking groove 321. The width D1 of the first side of the connecting reinforcement portion 3422 is greater than the width D2 of the second side, forming a trapezoidal connecting reinforcement portion 3422. The lever portion 3421 contacts and actuates the latch assembly 32, while the connecting reinforcement portion 3422 increases the connection area between the lever 342 and the connecting plate 341, preventing breakage between the lever 342 and the connecting plate 341, thereby improving the structural strength of the lever 32.

[0028] Specifically, a first side 3423 and a second side 3424 are provided between the first and second sides of the connecting reinforcement part 3422. The clamping leg α between the first side 3423 and the actuating part 3421 is smaller than the clamping leg β between the second side 3424 and the actuating part 3421. The first side 3423 is inclined to avoid the electronic lock assembly 33, thereby improving the structural compactness and reducing the volume of the lock body 3. The second side 3424 is inclined so that the actuating part 3421 moves closer to the center of the connecting reinforcement part 3422, thereby avoiding excessive eccentricity of the actuating part 3421 and making unlocking easier. Preferably, the clamping leg α is 140-160°, the clamping leg β is 162-182°, the width D1 is 20-30mm, and the width D2 is 5-10mm.

[0029] Specifically, the center of the connecting plate 341 has a D-shaped hole 3411 penetrating through it. Limiting connection holes 3412 are provided on both sides of the D-shaped hole 3411. The handle 31, facing the connecting plate 341, has a locking rod 311 and two limiting connection rods 312, respectively positioned on either side of the locking rod 311. The locking rod 311 is inserted into the D-shaped hole 3411, and the two limiting connection rods 312 are inserted into the two limiting connection holes 3412. The connecting plate 341 is connected to the D-shaped hole 3411 and the two limiting connection holes 3412 of the handle 31 via the locking rod 311 and the two limiting connection rods 312, forming a multi-point connection structure. This prevents the locking rod 311 from breaking due to single-point force when rotating the handle 31, improving reliability and stability.

[0030] Specifically, the cabinet door 2 is provided with at least one arc-shaped limiting groove 21. Any limiting connecting rod 312 passes through the arc-shaped limiting groove 21 and is inserted into the limiting connecting hole 3412, with the limiting connecting rod 312 engaging with the arc-shaped limiting groove 21. By limiting the handle 31 through the arc-shaped limiting groove 21, there is no need to set an additional limiting mechanism between the latch assembly 32 and the cabinet door 2, simplifying the structure and reducing costs. Alternatively, it can form a multiple limiting structure with the limiting mechanism between the latch assembly 32 and the cabinet door 2 to distribute the limiting force points, prevent the limiting mechanism from breaking, and improve reliability and stability.

[0031] Specifically, the two sides of the actuating part 3421 are bent upwards or downwards to form arc-shaped bends (not shown in the figure), and the arc-shaped bends abut against the inner wall of the unlocking slide 321. By forming arcs on both sides of the actuating part 3421 through the arc-shaped bends, and by contacting the inner wall of the unlocking slide 321 through the arc-shaped bends, the resistance during unlocking is reduced and the smoothness is improved.

[0032] Specifically, the lever 342 is located on the outer edge of the upper part of the connecting plate 341, and the unlocking slide 321 is vertically arranged, such as... Figure 3 As shown, in the locked state, the toggle switch 342 is set horizontally, as... Figure 4 As shown, the lever 342 is tilted in the unlocked state. The lever 342 is horizontal in the locked state. When unlocked, the side of the lever 342 is subjected to force, so that the direction of the force on the lever 342 and the connection line between the lever 342 and the connecting plate 341 are nearly perpendicular, so as to avoid the lever 342 bending during unlocking and locking, thereby reducing metal fatigue and improving reliability and stability.

[0033] Specifically, the bending angle of the lever 342 is 80° to 100°. Preferably, the bending angle of the lever 342 is 90°.

[0034] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
