Description

[0001] The present application belongs to the technical field of display connection equipment, and more specifically, relates to a lock, a locking structure and a display. Background Art

[0002] With the rapid development of science and technology, LED display screens, as an important tool for modern information display, are increasingly widely used, especially in large-scale events, exhibitions, performances and other occasions, the demand for rental of LED display screens has shown explosive growth. In order to meet this market demand, the installation speed and display effect of LED display screens have become key indicators of product competition.

[0003] At present, most of the LED display cabinets on the market are connected by edge locking, which is simple and fast, but it also exposes some problems in actual use. Some products only have a lock in the middle of one side. When multiple cabinets are spliced ​​together, due to insufficient locking points, it is easy to cause distortion between the cabinets, thus affecting the overall splicing effect and greatly reducing the display effect of the display.

[0022] Optionally, a second elastic member is further included, one end of the second elastic member is connected to the lock seat, and the other end of the second elastic member is connected to the external structure.

[0029] The present application provides a lock comprising a lock seat, a handle assembly, a lock body assembly and a linkage assembly. The lock seat is the main body of the lock, and is used to carry other components to ensure the stability of the overall structure. The handle assembly is rotatably connected to one side of the lock seat, and the user can hold and rotate it to realize the opening and closing operation of the lock. The lock seat is also connected to two, three or more lock body assemblies, and one end of each lock body assembly extends from the other side of the lock seat to the lock seat so as to cooperate with the lock hole or lock slot and other structures in the outside world to achieve a locking effect. By setting a plurality of lock body assemblies, the number of locking points between the displays is increased, and the problem of uneven force and unstable connection of the displays caused by too few locking points is effectively avoided, which greatly improves the connection safety and stability. Each lock body assembly has two working modes: locked state and unlocked state.

The linkage assembly is connected to the lock seat, and the linkage assembly is connected to the handle assembly.

The number and position of the lock holes correspond to the number and position of the lock body assembly, so that the lock body assembly on the lock can be connected to each lock hole accordingly. In the locked state, one end of the lock body assembly extends into the lock hole, and under the drive of the handle assembly, the lock body assembly is switched to the locked state to achieve a locked connection between the lock body assembly and the lock hole.

[0031] The present application provides a display, comprising the above-mentioned locking structure and at least two adjacent display frames. Among them, a lock hole is provided on one display frame, and a lock is connected to another adjacent display frame. When the two adjacent display frames are spliced, the lock on one display frame corresponds to the lock hole on the other display frame, and the lock body assembly extends into the lock hole. The user only needs to turn the handle assembly to switch the lock body assembly from an unlocked state to a locked state. In this process, a firm locking connection is formed between the lock body assembly and the lock hole, thereby realizing the connection of two adjacent display frames. Since the lock has a plurality of lock body assemblies spaced apart from each other, the number of locking points between two adjacent display frames is increased, which effectively avoids the problem of uneven force and unstable connection of the display caused by too few locking points, greatly improves the safety and stability of the display connection, and provides users with a more reliable and stable visual experience.

[0045] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0046] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0047] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0048] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0049] like Figures 1 to 3 As shown, the present application provides a lock that can form multiple locking points, has a better locking effect, and a more convenient locking process. It includes a lock base 1, a handle assembly 2, a lock body assembly 3, and a linkage assembly 4. The lock base 1 is used as the main body of the lock to carry other components and ensure the stability of the overall structure. The handle assembly 2 is rotatably connected to one side of the lock base 1, and the user can hold and rotate it to achieve the opening and closing operation of the lock. The lock base 1 is also connected to two, three or more lock body assemblies 3, and one end of each lock body assembly 3 extends out of the lock base 1 from the other side of the lock base 1, so that it can cooperate with the lock hole or lock groove and other structures in the outside world to achieve the locking effect. By setting a plurality of lock body assemblies 3, the number of locking points between the connected parts (such as displays) is increased, and the problem of uneven force and unstable connection of the display caused by too few locking points is effectively avoided, which greatly improves the connection safety and stability. Each lock body assembly 3 has two working modes: locked state and unlocked state. In the locked state, the lock body assembly 3 can be tightly connected to other displays to ensure a stable connection between them; in the unlocked state, the displays can be easily separated for easy disassembly and replacement. The linkage assembly 4 is connected to the lock seat 1, and the linkage assembly 4 is connected to the handle assembly 2. When the user turns the handle assembly 2, the linkage assembly 4 drives each lock body assembly 3 to achieve synchronous movement between the locked state and the unlocked state. This not only simplifies the locking process between the displays and improves the operating efficiency, but also ensures the coordination and consistency of the movement of each lock body assembly 3.

[0050] like Figures 1 to 3 As shown, in one embodiment of the present application, each lock body assembly 3 is arranged spaced apart from each other along a linear direction. It should be noted that the linear direction not only includes a straight direction, but can also be extended to a curved direction to meet the locking requirements in different scenarios. More specifically, in some cases, each lock body assembly 3 will be arranged spaced apart and balanced along the length direction of the lock seat 1, that is, a clear straight line trajectory. Such a layout not only ensures that each lock body assembly 3 can be stably fixed on the lock seat 1, but also makes the overall structure more compact and balanced. In other cases, when the shape of the lock seat 1 is designed to be arc-shaped, each lock body assembly 3 is arranged spaced apart along the arc direction of the lock seat 1. This curved layout not only fits the shape of the arc-shaped lock seat better, but also can layout the lock contacts in a two-dimensional direction compared to the linear layout, so that the locking effect and stability are better.

[0051] like Figures 1 to 3As shown, in one embodiment of the present application, the linkage assembly 4 includes a driving member, a linkage member, and a transmission member corresponding to the number of lock body assemblies 3. The driving member is connected to the handle assembly 2, and when the user turns the handle assembly 2, the driving member will rotate accordingly. The transmission member is directly connected to the corresponding lock body assembly 3, and the function of the transmission member is to effectively transfer the power on the driving member to the lock body assembly 3, thereby driving the lock body assembly 3 to move between the locked state and the unlocked state. The linkage member is connected between the driving member and the transmission member, which not only transmits the power on the driving member to each transmission member, but also ensures that each transmission member can move synchronously. This synchronous movement mechanism ensures the coordination and consistency of each lock body assembly 3 during the opening and closing process, thereby improving the stability and reliability of the entire lock system.

[0052] like Figures 1 to 3 As shown, in one embodiment of the present application, the driving member is a driving gear 41, the transmission member is a transmission gear 42, and the linkage member is a rack 43. The driving gear 41 and the transmission gear 42 are both meshed with the rack 43 for transmission, and the rack 43 is movably connected to the lock seat 1. When the user rotates the handle assembly 2, the driving gear 41 rotates accordingly, and the rotation of the driving gear 41 drives the rack 43 to slide in the linear direction in the lock seat 1. Because each transmission gear 42 is also meshed with the rack 43, the sliding of the rack 43 can drive each transmission gear 42 to rotate synchronously. In order to reduce the unit load on the rack 43, the number of the racks 43 is two, which are respectively meshed with the left and right sides of the driving gear 41. This double-sided meshing design not only enhances the stability of the structure, but also effectively disperses the pressure on the meshing teeth, thereby extending the service life.

[0053] In other embodiments of the present application, the driving member and the transmission member may also be in the form of a pulley or a sprocket. These options can also achieve the transmission of power, and each has its own unique advantages. For example, the pulley has the characteristics of smooth transmission and low noise, while the sprocket has the advantages of high transmission efficiency and strong carrying capacity. The corresponding linkage member is a belt or a chain, which cooperates closely with the pulley or sprocket to jointly complete the task of power transmission.

[0054] like Figures 1 to 3As shown, in one embodiment of the present application, the lock body assembly 3 includes a lock body fixing part 31 and a lock body movable part 32. The lock body fixing part 31 is connected to the lock seat 1, serving as the installation base of the lock body movable part 32 and providing support for the lock body movable part 32. The lock body movable part 32 is used to realize the opening and closing operation of the lock. The transmission gear 42 is connected to the lock body movable part 32. When the transmission gear 42 rotates under the drive of the rack 43, the lock body movable part 32 is driven to perform a corresponding rotation action so that the lock body movable part 32 switches between the locked state and the unlocked state. The lock body assembly 3 can be specifically a lock cylinder, a lock sleeve, a lock tube, etc. The lock body movable part 32 can be specifically a lock bar. The lock body movable part 32 can rotate or move on the lock body fixing part 31. When the transmission gear 42 rotates, the lock body movable part 32 is driven to rotate. In practical applications, the specific form of the lock body fixing part 31 can be flexibly selected according to actual needs. For example, it can be a common lock cylinder form, or a lock sleeve or lock tube structure. The lock body movable part 32, as the direct executor of the lock opening and closing action, can specifically be a lock rod or the like.

[0055] like Figures 1 to 3 , Fig.10 As shown, in one embodiment of the present application, the lock body fixing member 31 includes a threaded hole, and the lock body movable member 32 includes a threaded portion 321 and a lock portion 322. The lock portion 322 is in the shape of an elongated strip, that is, the length dimension of the lock portion 322 is greater than the width dimension. When the lock portion 322 is in the unlocked state, the long side of the lock portion 322 is parallel to the long side of the lock hole 6, so that the lock portion 322 can pass through the lock hole 6. When the lock portion 322 is in the locked state, the long side of the lock portion 322 is staggered with the long side of the lock hole 6, so that the lock portion 322 cannot be withdrawn from the lock hole 6. The lock body movable member 32 is movably connected to the threaded hole, and the threaded portion 321 is threadedly connected to the threaded hole. According to the characteristics of the threaded connection, when the transmission gear 42 rotates, the lock body movable member 32 can not only rotate in the threaded hole, but more importantly, due to the spiral structure of the thread, the lock body movable member 32 can also move in the threaded hole along the axial direction. This unique movement mode enables the lock head portion 322 to not only achieve circumferential offset locking when connected to the lock hole 6, but also to pull the lock hole 6 toward the lock body fixing part 31 through axial tension to achieve a tighter locking, thereby enhancing the stability and reliability of the locking.

[0056] like Figures 1 to 3 ,as well as Figure 8 and Fig. 9 As shown, in one embodiment of the present application, the handle assembly 2 includes a handle body 21 and a limiting structure 22. The handle body 21 is the main component operated by the user. The handle body 21 includes a rotating shaft portion 211, and the driving gear 41 is connected to the rotating shaft portion 211; it should be noted that the rotating shaft portion 211 and the handle body 21 can be an integrated structure, and for easy disassembly and maintenance, the rotating shaft portion 211 and the handle body 21 can also be a split structure.

[0057] The limiting structure 22 includes a limiting member 221, a clamping member 222 and a first elastic member 223. The limiting member 221 is fixedly connected to the lock seat 1. The limiting member 221 has a plurality of limiting protrusions arranged in sequence. The limiting member 221 is specifically a limiting gear, and the limiting protrusion is a limiting tooth on the limiting gear. The plurality of limiting protrusions provide a plurality of reliable abutting points for the clamping member 222. The clamping member 222 is connected to the handle body 21 in a hinged manner, so that it can rotate flexibly and form an effective clamping connection with the limiting protrusion. When the clamping member 222 is clamped with the limiting protrusion, the limiting structure 22 will form an effective limit on the handle body 21 to ensure that it remains stable when it does not need to rotate. When the user applies force to rotate the clamping member 222 and separate it from the limiting protrusion, the limiting effect of the limiting structure 22 on the handle body 21 will be released, and the handle body 21 will resume flexible rotation.

[0058] In this process, one end of the first elastic member 223 is connected to the handle body 21, and the other end is connected to the clamping member 222. The first elastic member 223 provides a stable elastic support for the clamping member 222. In this way, when the external force disappears, the clamping member 222 can automatically reset under the elastic force of the first elastic member 223, and form a clamping contact with the limiting protrusion, so as to accurately limit the handle body 21 to a predetermined position. In actual use, the user only needs to lightly press the clamping member 222 to separate it from the limiting protrusion, and then the handle body 21 can be easily rotated to the desired position. When the handle body 21 is rotated to the desired position, the clamping member 222 is released, and it will automatically clamp with the limiting protrusion under the action of the first elastic member 223, ensuring that the handle body 21 stays stably in the predetermined position.

[0059] like Figures 1 to 3 As shown, in one embodiment of the present application, a second elastic member 5 is further included, one end of the second elastic member 5 is connected to the lock seat 1, and the other end of the second elastic member 5 is connected to the external structure. In actual application, when the lock body movable member 32 is locked with the lock hole 6, the lock body movable member 32 will generate axial pulling force. After the pulling force is transmitted to the lock seat 1, if this pulling force is not effectively buffered and limited, it may cause strain to the lock seat 1, the lock hole 6 and even the external components. Therefore, through the elastic buffering effect of the second elastic member 5, when the lock body movable member 32 generates a large pulling force, the second elastic member 5 can be elastically deformed, and the lock seat 1 will move relative to the external structure, thereby playing a role in adjusting the pulling force, so that the pulling force on the lock body movable member 32 is always kept within a safe range.

[0060] like Figures 4 to 6As shown, the present application provides a locking structure, including a lock hole 6 and the lock in the above-mentioned embodiment. The number and position of the lock holes 6 correspond to the number and position of the lock body assembly 3, so that the lock body assembly 3 on the lock can be connected to each lock hole 6 accordingly. In the locked state, one end of the lock body assembly 3 extends into the lock hole 6, and under the drive of the handle assembly 2, the lock body assembly 3 is switched to the locked state to achieve the locked connection between the lock body assembly 3 and the lock hole 6. Similarly, under the drive of the handle assembly 2, the lock body assembly 3 is switched to the unlocked state, so that one end of the lock body assembly 3 can be withdrawn from the lock hole 6, completing the unlocking of the lock hole 6 and the lock. Since the locking structure of the present application has the lock in the above-mentioned embodiment, it also has the advantages of the lock in the above-mentioned embodiment.

[0061] like Figures 4 to 6 As shown, the present application provides a display, including the locking structure in the above embodiment and at least two adjacent display frames 7. Among them, the lock hole 6 is provided on one display frame 7, and the lock is connected to another adjacent display frame 7. When the two adjacent display frames 7 are spliced, the lock on one display frame 7 corresponds to the lock hole 6 on the other display frame 7, and the lock body assembly 3 extends into the lock hole 6. Next, the user only needs to turn the handle assembly 2 to switch the lock body assembly 3 from the unlocked state to the locked state. In this process, a firm locking connection is formed between the lock body assembly 3 and the lock hole 6, thereby realizing the connection of two adjacent display frames 7. Since the lock has a plurality of lock body assemblies 3 spaced apart from each other, the number of locking points between the two adjacent display frames 7 is increased, which effectively avoids the problem of uneven force and unstable connection of the display caused by too few locking points, greatly improves the safety and stability of the display connection, and provides users with a more reliable and stable visual experience. Since the display of the present application has the locking structure in the above embodiment, it also has the advantages of the locking structure in the above embodiment.

[0062] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
