[0002] Safes are protective containers used to store valuables, documents, and other important items, and are widely used in homes, businesses, and financial institutions. Locks, as a crucial component of safes, need to provide reliable locking while ensuring stable connection and smooth operation during frequent opening and closing. Traditional safe locks often employ simple pivot or snap-fit ​​connections, with locking mechanisms primarily relying on a single rotation or pressing action.

[0003] However, in actual use, traditional locks often have the following shortcomings at the connection with the safety box: the connection of existing locks usually relies only on screws, rivets or single shafts for fixation. The lock lacks a precise limiting fit structure when rotating. When the lock is used under repeated rotation or external force, the shaft is prone to loosening or falling off, resulting in an unstable connection between the lock and the box, thus affecting the locking performance of the safety box.

[0004] Therefore, existing safety box locks still have significant shortcomings in terms of limit protection and other aspects. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a lock and safety box for use in safety boxes. The lock and safety box structure of this invention can improve connection stability and limiting accuracy while ensuring rotational flexibility, thereby achieving reliable locking and long-term durability of the safety box.

The fixing block is provided with a slot. The fixing block is fixedly connected to the first connecting member, and a through connection gap is formed between the fixing block and the first connecting member. The connection gap is used to accommodate the limiting block. One end of the limiting block is fixedly connected to the first connecting member, and the other end of the limiting block is provided with a limiting protrusion on the side near the fixing block. The limiting protrusion extends into the slot, and a connecting and fixing space is formed between the limiting protrusion and the slot.

[0018] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0019] This utility model provides a lock for a safety box. By setting a rotating connection part that cooperates with a fixed block and a limiting block, the first connecting member forms multi-point support when connected to the safety box. The limiting block is provided with a limiting protrusion that extends into the slot of the fixed block to form a limiting constraint. It can automatically limit the lock when it rotates to a predetermined angle, effectively preventing the lock from loosening or falling off during rotation. At the same time, it prevents excessive rotation from causing structural displacement or damage, and ensures that the locking action is accurate and in place.

[0020] This utility model provides a lock for a safety box. By setting a connection gap between the fixed block and the limiting block, it not only provides the limiting block with room to move, but also buffers the mechanical stress during operation, reduces wear and impact, and extends the overall service life of the lock.

[0021] This utility model provides a lock for a safety box.

[0029] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the present invention. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0030] Example 1

[0031] like Figure 1-2 As shown, this utility model provides a lock for a safety box, including a first connecting member 1 and a second connecting member 2. The first connecting member 1 is connected to the second connecting member 2 via a rotating shaft 3. The second connecting member 2 is provided with a pressing buckle plate, which is fastened to the safety box. Rotating connecting portions 4 are provided on both sides of the end of the first connecting member 1 away from the second connecting member 2, and the first connecting member 1 is connected to the safety box via the rotating connecting portions 4. The rotating connecting portion 4 includes a fixing block 401 and a limiting block 402. The fixing block 401 is provided with a slot 401. 1. The fixing block 401 is fixedly connected to the first connector 1, and a through connection gap is formed between the fixing block 401 and the first connector 1. The connection gap is used to accommodate the limiting block 402. One end of the limiting block 402 is fixedly connected to the first connector 1, and the other end of the limiting block 402 is provided with a limiting protrusion 4021 on the side near the fixing block 401. The limiting protrusion 4021 extends into the slot 4011, and a connection fixing space is formed between the limiting protrusion 4021 and the slot 4011.

[0032] The lock for a safety box provided by this utility model includes a first connecting member 1 and a second connecting member 2, which are hinged together by a rotating shaft 3. In use, the second connecting member 2 can rotate relative to the first connecting member 1 under the drive of the rotating shaft 3. When the second connecting member 2 is pressed, it engages with the safety box's locking mechanism, thus achieving the locking function. When released, the latch is released, and the lock is unlocked, allowing the box to be opened. The rotating shaft connection ensures smooth and stable opening and closing with minimal operating force. The tight engagement between the lock and the safety box improves locking stability and anti-loosening performance, effectively preventing the safety box from accidentally opening during transportation or vibration.

[0033] The first connecting piece 1 is mounted on the safety box via the rotating connecting part 4. The fixing block 401 has a slot 4011, which cooperates with the limiting block 402. One end of the limiting block 402 is fixed to the first connecting piece 1, and the other end has a limiting protrusion 4021. The protrusion is embedded in the slot 4011 of the fixing block. Together, they form a connecting and fixing space, thereby preventing the lock from rotating excessively or falling out of the installation position. This structure makes the rotating connection of the lock more stable, preventing loosening or displacement during frequent opening and closing. The cooperation between the limiting protrusion 4021 and the slot 4011 realizes the automatic limiting function, ensuring the precise rotation angle of the lock and avoiding damage to the mechanism due to excessive rotation.

[0034] Meanwhile, since a through connection gap is formed between the fixing block 401 and the first connecting member 1, after the rotating connecting part 4 at one end is engaged with the safety box, the limiting block 402 deforms and bends inward, and then engages the rotating connecting part 4 at the other end with the safety box. Since one end of the limiting block 402 is connected to the first connecting member 1, the deformed limiting block 402 returns to its original shape after the engagement is completed, which facilitates installation and disassembly, and can absorb some of the impact force during operation, thus improving overall durability.

[0035] Furthermore, in another embodiment, an arc-shaped support plate 101 is provided between the two rotating connecting parts 4. The arc-shaped support plate 101 has a plurality of first protrusions 102, which are matched and connected to the safety box. By providing an arc-shaped support plate 101 between the two rotating connecting parts 4, with a plurality of first protrusions 102 on its outer surface, the first protrusions 102 engage with the grooves of the safety box during installation, thereby forming an arc-shaped contact surface support between the lock and the box body. This disperses the force during lock operation and prevents deformation of the connecting parts caused by single-point force. The snap-fit ​​between the first protrusions 102 and the safety box body improves the stability of the lock, making it less prone to loosening or shifting when subjected to external forces or during long-term use, and enhancing the bonding strength and impact resistance between the lock and the box body.

[0036] Furthermore, in another embodiment, the second connecting member 2 includes an integrally connected locking part 201, connecting part 202, and pressing part 203. A fixing groove is provided between the locking part 201 and the connecting part 202, and the fixing groove is matched and connected to the rotating shaft 3. The second connecting member 2 is integrally formed by the locking part 201, the connecting part 202, and the pressing part 203. The locking part 201 cooperates with the latch part of the safety box and is connected to the rotating shaft 3 through the fixing groove to realize the rotational opening and closing action. When the user presses the pressing part 203, the connecting part 202 drives the locking part 201 to rotate, so that the locking part fits against the latch position of the safety box, realizing locking. This integrated structure reduces the number of parts, makes the overall strength of the lock higher, and makes assembly simpler. The cooperation between the fixing groove and the rotating shaft 3 ensures that the locking action is smooth and reliable, and the operation is convenient and labor-saving, improving the user experience and structural stability of the lock.

[0037] Furthermore, in another embodiment, the end of the first connector 1 connected to the rotating shaft 3 extends inward, i.e., the first connector 1 is C-shaped. The inward extension of the end of the first connector 1 connected to the rotating shaft 3 forms a C-shaped structure, which can cover part of the area of ​​the second connector 2. The C-shaped opening structure provides support and protection for the rotating shaft when the lock rotates, and limits its rotation direction, increasing the overall coverage and torsional resistance of the lock, effectively preventing the rotating shaft from bending or falling off during use, and improving anti-pry and anti-vibration performance.

[0038] Furthermore, in another embodiment, the connecting portion 202 protrudes outward, and a plurality of reinforcing ribs are fixed inside the connecting portion 202. The reinforcing ribs extend to the pressing portion 203. The reinforcing ribs include a first reinforcing rib 2021 and a second reinforcing rib 2022. The first reinforcing rib 2021 is parallel to the second reinforcing rib 2022, and the width of the second reinforcing rib 2022 is smaller than the width of the first reinforcing rib 2021. The width of the second reinforcing rib 2022 is ≤5mm.

[0039] The connecting part 202 protrudes outward to enhance the operating space of the lock. Multiple reinforcing ribs 2021 and 2022 are set inside. The first reinforcing rib 2021 and the second reinforcing rib 2022 are arranged in parallel and extend to the pressing part 203 to form an internal skeleton structure to improve the overall rigidity, share local stress, effectively prevent the lock from deforming under external force or frequent pressing, and improve the load-bearing capacity and structural stability. At the same time, through the force distribution of the two reinforcing ribs of different widths, the impact resistance and durability are further enhanced, ensuring that the lock does not loosen or deform during long-term use.

[0040] like Figure 3-5As shown, this utility model provides a safety box, including two locks for the safety box, and also includes a lower box body 5, an upper box body 6, a handle 7 and a latch 8. The upper box body 6 is hinged to the lower box body 5, the handle 7 is provided on the lower box body 5, both locks are rotatably connected to the upper box body 6 and are provided at both ends of the handle 7, and the latch 8 is provided between the lower box body 5 and the upper box body 6.

[0041] Two locks are symmetrically arranged at both ends of the handles 7 on both sides of the lower box. The locking part 201 cooperates with the latch 8 on the upper box to achieve bidirectional locking of the box. When the user unlocks the locks on both sides at the same time and lifts the handle, the security box can be opened, further improving the anti-theft performance and operational stability.

[0042] Furthermore, in another embodiment, the upper housing 6 is provided with four mounting protrusions 601, and every two mounting protrusions 601 are used to connect a lock. On the side of the two mounting protrusions 601 that are close to each other, there is a connecting protrusion 602. The connecting protrusion 602 is connected between the limiting protrusion 4021 and the slot 4011 to form a connecting and fixing space.

[0043] Four mounting protrusions 501 are provided on the lower housing 5, with two protrusions for each lock. The connecting protrusions 502 between adjacent mounting protrusions are embedded in the connecting and fixing space formed by the limiting protrusions 4021 and the slots 4011, so as to realize the stable locking and positioning of the lock and the housing. This achieves the rapid positioning and stable installation of the lock, ensuring the installation accuracy and reliability of the lock without the need for additional fasteners. The cooperation between the connecting protrusions 602 and the limiting structure allows the lock to remain fixed when subjected to vibration or impact, improving the overall shock resistance and safety of use.

[0044] Furthermore, in another embodiment, a latching block 603 is provided between the two mounting protrusions 601, and the top of the latching block 603 is provided with a plurality of second protrusions 604, which engage with the first protrusion 102. The engagement of the two protrusions of the housing and the lock achieves bidirectional limiting of the lock, further enhancing the lock's resistance to loosening, preventing displacement of the lock under vibration or external force, and improving the stability and reliability of the assembly.

[0045] Furthermore, in another embodiment, the bottom of the buckle 603 extends away from the upper housing 6, and the locking portion 201 of the second connector 2 abuts against the bottom of the buckle 603. The bottom of the buckle 503 extends away from the upper housing 6, forming a limiting surface that contacts the locking portion 201. When the locking portion 201 rotates to the locked position, its bottom abuts against the buckle 503, thereby limiting its continued rotation and achieving the closing and locking of the safety box. The above structure makes the locking action more precise and reliable, prevents the locking portion from rotating excessively or misaligning, and improves the sealing and anti-vandalism performance of the safety box. Furthermore, in another embodiment, shoulder strap connecting structures 9 are provided on both sides of the upper housing 6. The shoulder strap connecting structures 9 are used to connect shoulder straps, further increasing the applicable scenarios of the safety box.

[0046] Working principle:

[0047] This utility model provides a lock for a safety box. In use, a first connecting member 1 is movably connected to a second connecting member 2 via a rotating shaft 3, forming a rotatable lock body structure. When the user presses the pressing part 203, the second connecting member 2 rotates around the rotating shaft 3, causing its locking part 201 to press tightly against the locking part of the safety box, thus achieving the locking operation and ensuring that the safety box is in the closed state. After the pressing part 203 is lifted, the second connecting member 2 returns to its original position and moves away from the locking part of the safety box, thereby achieving the unlocking function. Rotating connecting parts 4 are provided on both sides of the first connecting member 1, and the lock and safety box are stably rotated and installed through this structure on both sides. Specifically, the rotating connection part 4 is composed of a fixed block 401 and a limiting block 402. The fixed block 401 is provided with a slot 4011, and the limiting block 402 is provided with a limiting protrusion 4021. The limiting protrusion 4021 is inserted into the slot 4011 and forms a connection and fixing space. The connecting protrusion 502 on the safety box is inserted into the connection and fixing space formed by the limiting protrusion 4021 and the slot 4011. Through this structure, the first connecting piece 1 and the safety box are effectively limited and buffered during rotation, preventing the lock from loosening due to frequent rotation or force, while improving the stability and service life of the connection.
