[0033] The utility model provides a lock structure that allows users to lock and unlock the lock structure simply by operating a handle and a button, without the need for additional tools. This greatly simplifies the operation process and improves efficiency. The handle assembly and the snap assembly are both connected to the main body via fasteners, making the entire lock structure compact and small in size, making it easy to install and use in limited spaces. It also reduces material usage and reduces costs. In the locked state, the first limiting portion tightly abuts the first mating portion, and the elastic member applies a continuous force to the first limiting portion toward the first mating portion, ensuring the stability and reliability of the lock structure and effectively preventing accidental unlocking or loosening. Example

[0034] The present invention provides a locking structure. Figures 1 to 5 As shown, it includes: a main body 10, the main body 10 includes a first mounting portion 110 and a second mounting portion 120; a handle assembly 20, the handle assembly 20 includes a handle member 210 and a first fastener 220, the handle assembly 20 is connected to the first mounting portion 110 via the first fastener 220, the handle member 210 can move around the first fastener 220 toward the second mounting portion 120, and the handle member 210 includes a first matching portion 2110; a snap assembly 30, the snap assembly 30 includes a button member 310, a second fastener 320 and an elastic member 330, the snap assembly 30 is connected to the second mounting portion 120 via the first fastener 220, the button member 310 can move around the second fastener 320 toward the handle member 210, and the button member 310 includes a first limiting portion 3110;

[0035] In the locked state, the first limiting portion 3110 abuts against the first matching portion 2110 , and the elastic member 330 applies a force to the first limiting portion 3110 toward the first matching portion 2110 .

[0036] It is understandable that due to the use of fasteners and elastic members 330, the lock structure 1 can maintain good stability and durability during repeated use, reducing wear and damage caused by frequent operation. The lock structure 1 can be adjusted and optimized according to different application scenarios and needs, and is widely used in various occasions requiring quick locking and unlocking, such as electronic equipment, vehicles, furniture and other fields. In situations where safety must be guaranteed, such as child safety locks and anti-theft locks, the lock structure 1 can provide a reliable locking function, effectively preventing unauthorized access or operation, and improving overall safety.

[0037] More specifically, the handle assembly 20 may be symmetrically provided with a handle member 210 and a first fastener 220 on both sides. Thus, since the handle member 210 and the first fastener 220 are symmetrically arranged on both sides of the handle assembly 20, the user can operate from either or both sides. The bilaterally symmetrical structure makes the handle assembly 20 more balanced when subjected to force, reducing the deflection or instability that may be caused by unilateral operation. This is crucial for ensuring the stability and reliability of the locking structure 1 during long-term use. Due to the even distribution of force, excessive wear on individual components is reduced, thereby extending the service life of the locking structure 1. In addition, the fasteners arranged on both sides also provide additional fixing points, enhancing the stability of the overall structure.

[0038] like Figure 2 As shown, more specifically, the first mounting portion 110 and the second mounting portion 120 may be arranged on different surfaces of the main body 10. Placing the first mounting portion 110 and the second mounting portion 120 on different surfaces of the main body 10 respectively can make more effective use of space and avoid mutual interference or occupying too much space on the same plane. By dispersing the mounting parts on different surfaces of the main body 10, the force points can be dispersed, and the pressure concentration on a single surface can be reduced, thereby enhancing the structural strength and stability of the entire locking structure 1. This design helps to prevent deformation or damage caused by uneven force. Different installation environments have different requirements for the layout of the locking structure 1. The first mounting portion 110 and the second mounting portion 120 are respectively placed on different surfaces of the main body 10, so that the locking structure 1 can more flexibly adapt to diverse installation requirements, such as horizontal installation, vertical installation or inclined installation.

[0039] like Figure 1 and Figure 3 As shown, the handle 210 further includes a second mating portion 2120, which is U-shaped or has another identical or similar shape. More specifically, the handle 210 further includes a stopper 2130, and the main body 10 is provided with a second stopper 140 that mates with the stopper 2130. The handle 210 further includes a gripping portion 2140, which is provided at one end of the handle 210.

[0040] As you can understand, the handle 210 is provided with a limiter 2130, while the main body 10 has a second limiter 140 that mates with the limiter 2130. This restricts the range of movement of the handle 210 in a specific direction, preventing excessive movement or misoperation. The cooperation between the limiter 2130 and the second limiter 140 ensures the stability and accuracy of the handle 210 during opening and closing. This reduces the risk of damage caused by improper operation and increases the service life of the locking structure 1. Furthermore, the limiter design provides users with clear operational feedback, enhancing operational convenience and reliability.

[0041] Among them, the limiting member 2130 can be a limiting column. The first fastener 220 and the second fastener 320 are both pins or other components that can perform the same or similar functions. More specifically, the elastic member 330 can be a torsion spring or a tension spring. The limiting column, as the limiting member 2130, can accurately limit the position and range of the handle member 210 during movement through its specific shape and size. The limiting column can ensure that the handle member 210 does not exceed the predetermined movement trajectory during operation, thereby preventing damage or misoperation caused by excessive movement. In addition, the limiting column and the second limiting portion 140 (such as a limiting groove or limiting hole) on the main body 10 are tightly matched, further improving the stability and safety of the locking structure 1. The pin serves as a fastener, which passes through the holes or grooves on the handle assembly 20 and the main body 10 to firmly connect the two together. The pin has the advantages of simple structure, easy installation, and reliable connection. In the lock structure 1, the use of pins as fasteners ensures a secure connection between the handle assembly 20 and the main body 10, preventing them from loosening or falling off. Pins are also easy to maintain and replace, reducing maintenance costs and time. Torsion springs or tension springs serve as elastic members 330, providing the lock structure 1 with the necessary elasticity and restoring force. In the locked state, they exert a certain force on the button member 310 or the handle member 210 to maintain the stability of the locked state; during the unlocking process, they provide a restoring force, allowing the button member 310 or the handle member 210 to smoothly return to their initial position. Torsion springs and tension springs are both commonly used elastic elements with advantages such as small size, high strength, and long life. Using one of these two elastic members 330 in the lock structure 1 ensures that the lock structure 1 has stable elasticity and restoring force during the locking and unlocking processes, thereby improving the reliability and durability of the lock structure 1. At the same time, they also simplify the design and production process of the lock structure 1, reducing manufacturing costs.

[0042] like Figure 1 and Figure 2As shown, more specifically, the main body 10 further includes a receiving portion 130 adapted to the handle member 210, and the receiving portion 130 is provided on one side of the second mounting portion 120. It will be understood that the provision of the receiving portion 130 allows the assembled handle member 210 to be flush with the main body 10 in the locked state and not protrude from the surface of the main body 10. The main body 10 not only includes the first mounting portion 110 and the second mounting portion 120, but also has an additional receiving portion 130 adapted to the handle member 210 provided on one side of the second mounting portion 120. This receiving portion 130 is designed to tightly accommodate the handle member 210 (especially when the handle member 210 is in the locked state), making it flush or almost flush with the surface of the main body 10, thereby preventing the handle member 210 from protruding from the surface of the main body 10.

[0043] In this way, the handle 210 is flush with the main body 10 when locked, avoiding an abrupt appearance and making the entire lock structure 1 look neater and more beautiful. Because the handle 210 does not protrude from the surface of the main body 10, users are less likely to accidentally touch it during daily use, thereby reducing the risk of unlocking the lock structure 1 due to misoperation. The accommodating portion 130 provides a safe "safe haven" for the handle 210. When the lock structure 1 is not in use, the handle 210 can be hidden within the accommodating portion 130, reducing direct contact with the external environment and thus reducing the risk of damage caused by scratches, collisions, etc. The provision of the accommodating portion 130 makes the lock structure 1 more compact in overall layout, saving space. This is very beneficial in situations where the lock structure 1 needs to be installed in a limited space. When the user operates the lock structure 1, since the handle 210 is flush with the main body 10, it is easier to find and grasp the handle 210 for operation. At the same time, since the risk of accidental touch and the protrusion of the handle 210 are reduced, the overall user experience will also be improved.

[0044] Compared with the prior art, the lock structure 1 provided in the embodiment of the present invention allows the user to lock and unlock the lock structure 1 by simply operating the handle 210 and the button 310, without the need for additional tools. This greatly simplifies the operation process and improves efficiency. The handle assembly 20 and the snap assembly 30 are both connected to the main body 10 via fasteners, making the entire lock structure 1 compact and small in size, making it easy to install and use in a limited space. This also reduces the use of materials and reduces costs. In the locked state, the first limiting portion 3110 is in close contact with the first matching portion 2110, and the elastic member 330 applies a continuous force toward the first matching portion 2110 to the first limiting portion 3110, ensuring the stability and reliability of the lock structure 1 and effectively preventing accidental unlocking or loosening. Example

[0045] Based on the same concept, an embodiment of the present invention further provides a power box 2, comprising the locking structure 1 of any one of the first embodiments.

[0046] like Figure 5 As shown, the power supply box 2 of the present embodiment can be provided with a locking structure 1 at each end of the power supply box 2. It is understood that the power supply box 2 can also be provided with a locking platform 21, the shape and size of which are adapted to the second limiting portion 140 of the locking structure 1. In this way, when the locking structure 1 is in the locked state, the locking platform 21 can also limit the second limiting portion 140.

[0047] The power box 2 of the present embodiment incorporates the locking structure 1 described in any one of the first embodiments into its structure. This means that the closing and locking mechanism of the power box 2 adopts an efficient and reliable locking method, ensuring the stability and safety of the power box 2 in the closed state.

[0048] In order to further optimize the locking effect of the power box 2, a locking structure 1 can be provided at each end of the power box 2. This double locking structure not only improves the sealing performance of the power box 2, but also increases the stability of its structure, making the power box 2 less likely to open when subjected to external force.

[0049] Furthermore, the power supply box 2 may be provided with latching platforms 21. The shape and size of these latching platforms 21 are carefully designed to mate with the second stopper 140 of the latch mechanism 1. When the latch mechanism 1 is locked, the latching platforms 21 cooperate with the second stopper 140, providing an additional retaining effect. This further enhances the stability and reliability of the locked state of the power supply box 2 and prevents unlocking due to accidental collision or vibration.

[0050] It can be understood that the double lock design and the cooperation between the buckle platform 21 and the second limiting portion 140 make the power box 2 have a higher sealing performance in the closed state, effectively preventing the intrusion of external factors such as dust and moisture. The limiting effect of the double lock structure 1 and the buckle platform 21 jointly improves the overall stability of the power box 2, so that it can maintain a stable closed state in various usage environments. The stable locking mechanism reduces the risk of accidental opening of the power box 2, thereby protecting the safety of the internal components and circuits of the power box 2. When using the power box 2, users can complete the opening and closing operations more easily and quickly, while enjoying a safer and more reliable use experience. Example

[0051] Based on the same concept, an embodiment of the present invention further provides an LED display screen, comprising a power box 2 , wherein both sides of the power box 2 are respectively provided with a locking structure 1 of any one of the items in the first embodiment.

[0052] LED displays are typically composed of multiple, modular display units (such as unit display panels or unit display cabinets). These units are connected together to form a complete display. Furthermore, LED displays typically require a control system to drive and display images.

[0053] In the embodiment of the present invention, the power box 2 is an important component of the LED display screen and is responsible for providing a stable power supply to the display screen. In order to improve the stability and safety of the power box 2, a locking structure 1 can be provided on each side of the power box 2 in this embodiment.

[0054] It can be understood that the lock structure 1, through its unique locking mechanism, can ensure the stability of the power box 2 in the closed state. Even when subjected to external force, the power box 2 can remain tightly closed to prevent damage to internal components and circuits. The operation of the lock structure 1 is usually simple and quick. The user only needs to press or rotate it lightly to open and close the power box 2. This design not only improves work efficiency but also reduces the difficulty of operation. The stable locking mechanism reduces the risk of accidental opening of the power box 2, thereby protecting the power supply system and circuit safety inside the power box 2. This helps prevent display screen failures caused by power supply interruptions or short circuits. The design of the lock structure 1 takes into account the needs of power boxes 2 of different models and specifications. By adjusting the size and shape of the lock structure 1, it can be adapted to power boxes 2 of different sizes and shapes, thereby improving the versatility and adaptability of the lock structure 1.

[0055] The robust design of the power box 2 helps improve the overall performance stability of the LED display and reduce display failures caused by power supply issues. By preventing the power box 2 from accidentally opening, the locking mechanism 1 enhances the safety of the LED display during use and reduces the risk of electrical accidents. The convenient operation and secure locking mechanism enhance the user experience and increase user satisfaction with the LED display.

[0056] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
