The locking member is sleeved inside the connecting base and rotatably connected to it. One end of the locking member extends into the through hole, and a locking portion is provided at the end of the locking member near the through hole. The other end of the locking member has a threaded hole, and an adjusting member is provided within the threaded hole. The outer surface of the adjusting member has a threaded structure. The adjusting handle is sleeved on the end of the connecting base away from the locking plate base and is fixedly connected to the locking member via the adjusting member. The adjusting member rotates to adjust the distance between the adjusting handle and the connecting base.

[0008] Furthermore, the adjusting handle is provided with a recessed receiving groove on the side near the locking plate base, the connecting base is sleeved in the receiving groove, and a stop member is also provided in the receiving groove. The stop member is rotatably connected to the adjusting handle, and one end of the stop member extends to the position of the connecting base and contacts the outer surface of the connecting base, while the other end of the stop member is located outside the receiving groove.

[0009] Furthermore, the stop member includes a handle portion, a connecting portion, and a stop portion. One end of the handle portion is fixedly connected to one end of the connecting portion, and the other end of the handle portion extends outward from the receiving groove in a direction away from the connecting base. The connecting portion is rotatably connected to the adjusting handle, and the other end of the connecting portion is fixedly connected to one end of the stop portion. The other end of the stop portion extends in the direction of the connected base and contacts the outer surface of the connecting base.

[0010] Furthermore, a first limiting member is provided on the outer surface of the connecting base, and a second limiting member is provided on the stop portion at a position corresponding to the first limiting member, the second limiting member cooperating with the first limiting member to lock together.

[0011] Furthermore, the first limiting member is a first tooth, which is vertically arranged circumferentially along the outer surface of the connecting base, and the second limiting member is a second tooth, which meshes with the first tooth.

[0012] Furthermore, the locking device also includes a positioning baffle, which is disposed on the side of the stop member near the locking plate base, and the positioning baffle is fixedly connected to the adjusting handle.

[0013] Furthermore, the number of through holes is at least two, and the number of locking devices is the same as the number of through holes.

[0014] Furthermore, the inner wall of the connecting base is provided with an internal thread structure, and the outer surface of the locking member is provided with an external thread structure that matches the internal thread structure, and the locking member is threadedly connected to the connecting base.

[0015] Furthermore, the locking member has an internal hollow structure, and the locking part is disposed within the hollow structure of the locking member.

[0016] Furthermore, the locking part includes a locking boss, the number of which is at least two, and a gap is provided between adjacent locking bosses.

[0017] By employing the above technical solution, the present invention provides a finely adjustable LED display quick-release lock, which has at least the following beneficial effects:

[0018] 1. The adjustable LED display quick-release lock provided in this application embodiment has a locking component. One end of the locking component near the base of the locking plate has a locking part, and the other end of the locking component has a threaded hole. An adjusting component is installed in the threaded hole. The adjusting handle is fixedly connected to the threaded hole on the locking component through the adjusting component. When the adjusting component is rotated, since the adjusting component is threaded to the threaded hole, the adjusting component can drive the adjusting handle to move linearly, so as to change the distance between the adjusting handle and the locking component. This avoids the locking part on the locking component from developing a gap between itself and the display screen in the locked state due to wear during use, thereby improving the locking firmness, preventing the display screen from falling off, and improving safety.

[0019] 2. The adjustable LED display quick-release lock provided in this application embodiment is provided with a lock plate base, on which a through hole is provided. A locking device is fixedly connected at the through hole position. The locking device includes a connecting base, a locking member and an adjusting handle. When the adjusting handle is rotated, it drives the locking member to rotate, thereby locking the display screen by the locking part on the locking member. This reduces the difficulty of single-person splicing, is convenient and quick to operate, saves time and effort, and improves assembly efficiency.

[0020] 3. The adjustable LED display quick-release lock provided in this application embodiment includes a stop component, which comprises a handle, a connecting part, and a stop part. The connecting part is approximately V-shaped and has a connecting through hole. A connecting shaft is provided in the receiving groove. The connecting part is sleeved on the outer surface of the connecting shaft through the connecting through hole, and the connecting part is rotatably connected to the connecting shaft. The handle is fixedly connected to one end of the connecting part, and the stop part is fixedly connected to the other end of the connecting part. When the handle is turned, the handle can rotate around the connecting through hole as the center. The handle drives the stop part to rotate around the connecting through hole in a circle, thereby causing the stop part to contact or separate from the outer surface of the connecting base, thereby preventing or allowing the rotation of the adjustment handle to improve the safety of use.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This application provides a finely adjustable LED display quick-release lock for connecting adjacent displays. It addresses the problem in the prior art where the locking components are prone to wear during use, resulting in gaps in the locking components when locked, thus preventing the display from being locked and posing a risk of the display falling and creating a safety hazard. The following will describe the details in conjunction with the accompanying drawings.

[0034] Please see Figure 1 , Figure 1 This is a three-dimensional structural diagram of the adjustable LED display quick-release lock provided in this application embodiment. As can be seen from the figure, the adjustable LED display quick-release lock provided in this application embodiment mainly includes a locking plate base 100 and a locking device 300. One side of the locking plate base 100 contacts the display screen, and the locking device 300 is located on the other side of the locking plate base 100. The locking plate base 100 is used to support the locking device 300 and connect adjacent display screens. The locking device 300 is used to fix the display screens, thereby enabling the display screens to be spliced.

[0035] For example, please refer to Figure 1 And see Figure 2 , Figure 2This is a schematic diagram of the adjustable LED display quick-release locking plate base 100 provided in this embodiment. As can be seen from the diagram, the locking plate base 100 is generally a square plate structure. A through hole 200, which is circular, is provided on the side of the locking plate base 100. A locking device 300 is fixedly connected to the corresponding position of the through hole 200, and the locking device 300 locks the display screen through the through hole 200. It is understood that the locking plate base 100 can also be circular or other shapes that facilitate assembly; the shape of the locking plate base 100 is not limited here.

[0036] For further information, please refer to the following: Figure 2 As shown in the diagram, there are four through holes 200, each positioned at one of the four corners of the locking plate base 100. There are also four locking devices 300, which are fixedly connected to the corresponding positions of the four through holes 200. This facilitates simultaneous locking of the displays around the assembly connection points, reducing the number of locks required, lowering costs, and improving work efficiency. It is understandable that there could also be two through holes 200, with the same number of locking devices 300, to lock two adjacent displays. Of course, the number of through holes 200 can also be set to multiple to meet different installation requirements.

[0037] For further information, please refer to the following: Figure 2 As can be seen from the figure, the locking plate base 100 is also provided with positioning holes. The positioning holes are located at the center of the locking plate base 100. The positioning holes are circular through holes. Four through holes 200 are distributed on the circumference of the positioning holes to lock the four locking devices 300. Positioning elements are provided on the inner wall of the positioning holes. The positioning elements cooperate with the positioning devices on the display screen to perform positioning, so as to position the locking plate base 100 during installation and improve installation efficiency.

[0038] For example, please refer to Figure 1 And see Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the adjustable LED display quick-release locking device 300 provided in an embodiment of this application. Figure 4This is an exploded view of the adjustable LED display quick-release locking device 300 provided in this application embodiment. As shown in the figure, the locking device 300 mainly includes a connecting base 301, a locking member 302, and an adjusting handle 303. The connecting base 301 is a hollow circular cylindrical structure, with one end fixedly connected to the side of the locking plate base 100 away from the display screen. The hollow structure of the connecting base 301 corresponds to the through hole 200 on the locking plate base 100. The locking member 302 is also a circular cylindrical structure, fitted inside the hollow structure of the connecting base 301. The locking member 302 is rotatably connected to the connecting base 301 and can move linearly within the connecting base 301. The inner diameter of the through hole 200 is larger than the outer diameter of the locking member 302, allowing the locking member 302 to move into the through hole 200. A locking part 3021 is provided at one end of the locking member 302 near the locking plate base 100, used to lock the display screen. A threaded hole 3023 is provided at the other end of the locking member 302, containing an adjusting component. The adjusting component is a circular cylindrical structure with a threaded structure on its outer surface, and is threadedly connected to the threaded hole 3023. An adjusting handle 303 is fixedly connected to the threaded hole 3023 on the locking member 302 via the adjusting component. The adjusting handle 303 drives the locking member 302 to rotate, thereby locking the display screen with the locking part 3021 on the locking member 302. When in use, rotating the adjusting component causes the adjusting component to be threaded into the threaded hole 3023. This allows the adjusting component to drive the adjusting handle 303 to move linearly, thereby changing the distance between the adjusting component and the locking part 302. This prevents the locking part 3021 on the locking part 302 from developing a gap between itself and the display screen in the locked state due to wear during use, thus improving the locking firmness, preventing the display screen from falling off, and enhancing safety.

[0039] Furthermore, please combine Figure 2 and Figure 3 And see Figure 5 , Figure 5 This is a schematic diagram of the adjustable LED display quick-release lock adjustment handle 303 provided in this application embodiment. As can be seen from the figure, the adjustment handle 303 includes a fixing part 3032 and an operating part 3033. The fixing part 3032 has a recessed receiving groove 3031 on the side facing the lock plate base 100. The receiving groove 3031 includes a top wall and side walls extending downward around the perimeter of the top wall. The bottom opposite the top wall is an open structure. During assembly, the connecting base 301 and the locking member 302 enter the receiving groove 3031 through the open structure at the bottom of the receiving groove 3031.

[0040] For further information, please refer to the following: Figure 2 and Figure 3As can be seen from the figure, the locking device 300 also includes a stop 304, which is rotatably connected to the adjusting handle 303. One end of the stop 304 extends to the connection position and contacts the outer surface of the connecting base 301, while the other end of the stop 304 extends to the outside of the receiving groove 3031 in a direction away from the connecting base 301. The stop 304 is used to prevent the driving locking member 302 of the adjusting handle 303 from rotating.

[0041] For specific details, please refer to... Figure 2 and Figure 3 And see Figure 6 , Figure 6 This is a schematic diagram of the adjustable LED display quick-release lock stop 304 provided in this application embodiment. As shown in the figure, the stop 304 includes a handle portion 3041, a connecting portion 3042, and a stop portion 3043. The connecting portion 3042 is approximately V-shaped and has a connecting through hole. A connecting shaft is disposed within a receiving groove 3031, and the connecting portion 3042 is rotatably connected to the connecting shaft within the receiving groove 3031 through the connecting through hole. One end of the handle portion 3041 is fixedly connected to one end of the connecting portion 3042, and the other end of the handle portion 3041 extends away from the connecting base 301 to the outside of the receiving groove 3031 and continues to extend along the direction of the operating portion 3033 of the adjustment handle. One end of the stop portion 3043 is fixedly connected to the other end of the connecting portion 3042, and the other end of the stop portion 3043 extends towards the connecting base 301 and contacts the outer surface of the connecting base 301. When in use, the handle is turned so that the handle part 3041 rotates around the connecting through hole, thereby driving the stop part 3043 to rotate around the connecting through hole. This causes the stop part 3043 to contact or separate from the outer surface of the connecting base 301, thereby preventing or allowing the rotation of the adjustment handle 303.

[0042] For example, please refer to Figure 2 and Figure 3 And see Figure 7 , Figure 7 This is a schematic diagram of the adjustable LED display quick-release lock connecting base 301 provided in the embodiment of this application. In order to improve the blocking effect, a first limiting member 3011 is provided on the outer surface of the connecting base 301, and a second limiting member 305 is provided on the blocking part 3043 at a position corresponding to the first limiting member 3011. The second limiting member 305 and the first limiting member 3011 cooperate with each other to block.

[0043] Specifically, the first limiting member 3011 is a first tooth, which is vertically arranged along the outer surface of the connecting base 301. The second limiting member 305 is a second tooth, which meshes with the first tooth. The second tooth and the first tooth cooperate to stop the movement.

[0044] Furthermore, the locking device 300 includes a positioning baffle 400, which is fixedly connected to the open position of the receiving groove 3031. After assembly, the positioning baffle 400 closes a part of the receiving groove 3031, and the positioning baffle 400 is located on the side of the stop member 304 near the locking plate base 100, so that the positioning baffle 400 can prevent the stop member 304 from falling off, thereby improving the safety of use.

[0045] For example, please refer to [the document / reference]. Figure 7 The connecting base 301 has an internal hollow structure, and an internal thread structure is provided on the inner wall of the hollow structure. The outer surface of the locking member 302 is provided with an external thread structure that matches the internal thread structure. The locking member 302 is threadedly connected to the connecting base 301 through the cooperation of the external thread structure and the internal thread structure. In use, rotating the locking member 302 causes the external thread structure on the outer surface of the locking member 302 to cooperate with the internal thread structure on the inner wall of the connecting base 301, converting the rotational motion of the locking member 302 into linear motion. This allows the locking member 302 to move linearly within the hollow structure of the connecting base 301, thereby changing the height of the locking part 3021 on the locking member 302, and thus locking is achieved through the locking part 3021.

[0046] For example, please refer to Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the first angle structure of the locking member of the adjustable LED display quick-release lock provided in the embodiment of the application. Figure 9 The second angle structure diagram of the locking member of the adjustable LED display quick-release lock provided in the application embodiment shows that the locking member 302 is a hollow circular columnar structure, and the locking part 3021 is disposed on the inner wall of the hollow structure of the locking member 302.

[0047] Specifically, the locking part 3021 includes locking bosses 3022, with at least two locking bosses 3022 arranged circumferentially along the inner wall of the locking member 302, and a gap is provided between adjacent locking bosses 3022. In use, the connecting device on the display screen passes through the gap between adjacent locking bosses 3022, thereby facilitating assembly and disassembly.

[0048] The adjustable LED display quick-release lock provided in this application embodiment includes a locking member 302. One end of the locking member 302 near the lock plate base 100 has a locking portion 3021, and the other end has a threaded hole 3023. An adjusting component is disposed within the threaded hole 3023. An adjusting handle 303 is fixedly connected to the threaded hole 3023 on the locking member 302 via the adjusting component. Rotating the adjusting component, due to its threaded connection to the threaded hole 3023, allows the adjusting component to drive the adjusting handle 303 to move linearly. The distance between the adjusting handle 303 and the locking member 302 is changed, thereby preventing the locking part 3021 on the locking member 302 from creating a gap between it and the display screen in the locked state due to wear during use, improving the locking firmness, preventing the display screen from falling off, and improving safety. The adjustable LED display quick-release lock provided in this application embodiment is provided with a locking plate base 100, on which a through hole 200 is provided, and a locking device 300 is fixedly connected at the position of the through hole 200. The locking device 300 includes a connecting base 301, a locking member 302, and an adjusting handle 303. When the adjustment handle 303 rotates, it drives the locking member 302 to rotate, thereby locking the display screen with the locking part 3021 on the locking member 302. This reduces the difficulty of single-person splicing, makes operation convenient and quick, saves time and effort, and improves assembly efficiency. The adjustable LED display quick-release lock provided in this application embodiment is equipped with a stop member 304, which includes a handle part 3041, a connecting part 3042, and a stop part 3043. The connecting part 3042 is approximately V-shaped and has a connecting through hole. A connecting shaft is provided in the receiving groove 3031. 2. The connecting part 3042 is rotatably connected to the connecting shaft through the connecting through hole. The handle part 3041 is fixedly connected to one end of the connecting part 3042, and the stop part 3043 is fixedly connected to the other end of the connecting part 3042. When the handle part 3041 is turned, the handle part 3041 can rotate around the connecting through hole. The handle part 3041 drives the stop part 3043 to rotate around the connecting through hole, thereby causing the stop part 3043 to contact or separate from the outer surface of the connecting base 301, thereby preventing or allowing the rotation of the adjusting handle 303, so as to improve the safety of use.

[0049] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
