Description

Technical Field

[0001] This utility model relates to the field of display splicing technology, and in particular to a fast splicing lock for LED displays. Background Technology

[0002] Display splicing is a technology that combines multiple display units to achieve large-size, high-resolution images. It is widely used in various fields such as monitoring and dispatching, conference presentations, and advertising.

[0003] In existing technology, a steel wire rope lock is used when splicing displays. This lock consists of a mounting bracket, a steel wire rope, and a lock. In use, the steel wire rope is looped around the component to be locked, inserted into the lock, and then pulled out and tightened from the other end of the lock. The steel wire rope is automatically locked by the lock, thus securing the relevant components of the display screen. However, in actual use, when disassembling the spliced ​​display screen, the tension of the display screen causes the steel wire rope to tighten, requiring the user to exert considerable force to pull the lever to unlock the steel wire rope, causing inconvenience to the disassembly process. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a quick-connect locking mechanism for LED displays to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a quick-connect locking mechanism for LED displays, including a mounting frame. A constraint frame is fixedly connected to one side of the mounting frame, and a movable seat is inserted into the constraint frame. Both the constraint frame and the movable seat are non-circular structures. An unlocking rod is rotatably connected to the mounting frame and threadedly connected to the movable seat. A steel wire rope is fixedly connected to the outer end of the movable seat. A locking frame is provided at the other end of the mounting frame. A conical cavity is formed inside the locking frame, and a collar is provided inside the conical cavity. A spherical groove is formed on the side of the collar, and a friction ball that can make local displacement is provided inside the spherical groove. A movable groove is formed on the side of the locking frame, and a lever fixedly connected to the collar is provided at the movable groove. An end cap is provided at the end of the locking frame, and a spring is provided on the end cap. Both the locking frame and the end cap have through holes through which the steel wire rope can pass.

[0007] The above technical solution works as follows: When the lock needs to be disassembled, the unlocking lever is rotated. Under the constraint of the constraint frame, the unlocking lever causes the moving seat to shift. The movement of the moving seat causes one end of the wire rope to loosen partially, allowing the collar to move. Then, by holding the relevant display screen structure and moving the lever, the collar moves, and the friction ball loses the constraint of the conical cavity, making partial outward displacement within the spherical groove, thus unlocking the wire rope. The wire rope can then be pulled to remove it from the lock frame, thus disassembling the lock.

[0008] Preferably, in any of the above embodiments, the mounting frame includes an arc-shaped portion in the middle and horizontal portions at both ends of the arc-shaped portion, and the constraint frame and the locking frame are respectively disposed on the two horizontal portions.

[0009] The above technical solution employs an arc-shaped structure in the middle of the mounting frame to better adapt to fixed foundations such as circular columns. The two horizontal sections facilitate the installation of the constraint frame and locking frame.

[0010] Preferably, the end of the wire rope is provided with a tapered connector, and the end of the unlocking rod is fixedly connected with a rotating handle.

[0011] The above technical solution allows for easy insertion of the connector at the end of the wire rope into the locking frame. A handle is provided at the end of the locking bar for easy rotation by the user.

[0012] Preferably, in any of the above solutions, a limiting groove is provided in the constraint frame, and a limiting block located in the limiting groove is fixedly connected to the side of the movable seat.

[0013] The above technical solution uses a limiting groove and a limiting block to constrain the moving seat, which can prevent the moving seat from displacing in other directions and also prevent the moving seat from completely detaching from the constraint frame.

[0014] Preferably, one end of the mounting bracket is fixedly connected to a connecting sleeve, and the locking frame is threadedly connected to the connecting sleeve.

[0015] The above technical solution involves using a connecting sleeve to connect the locking frame and the mounting bracket. When needed, such as when pulling the wire rope to lock it, the locking frame can be rotated to adjust its extension length from the connecting sleeve, thereby tightening the wire rope. This way, during the final stage of tightening, there is no need to pull the wire rope, avoiding excessive stress on the wire rope and discomfort to the hand.

[0016] Preferably, in any of the above schemes, there are at least three friction balls that are evenly arranged circumferentially on the collar.

[0017] The above technical solution involves multiple friction balls that apply frictional constraints to the wire rope from different directions, making the locking mechanism more secure when tightened.

[0018] Preferably, in any of the above solutions, the locking frame has movable grooves on both sides, and the outer side of the lever has rough texture.

[0019] The above technical solution utilizes two movable slots and two levers to facilitate the user's rotation of the locking frame. The textured surfaces on the levers effectively increase friction when the user grips the device, preventing slippage.

[0020] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. This LED display screen features a quick-connect locking mechanism. Through a structure including a constraint frame, a movable base, an unlocking rod, a steel wire rope, a locking frame, and a conical cavity, the locking mechanism works as follows: When the locking mechanism needs to be disassembled, rotating the unlocking rod, constrained by the constraint frame, causes the movable base to shift. This movement loosens one end of the steel wire rope, allowing the collar to move. Then, by holding the relevant display screen structure and moving the lever, the collar moves, and the friction ball, freed from the conical cavity's constraint, shifts outward within the spherical groove, unlocking the steel wire rope. The steel wire rope can then be pulled out of the locking frame, thus disassembling the locking mechanism. Even if the steel wire rope becomes taut during use, it can be loosened by rotating the unlocking rod, making disassembly even more convenient.

[0021] 2. This LED display screen features a quick-connect locking mechanism. The limiting groove and limiting block constrain the moving seat, preventing displacement in other directions and avoiding complete detachment from the constraint frame. A connecting sleeve connects the locking frame to the mounting bracket. When needed, such as when tightening the steel wire rope, the locking frame can be rotated to adjust its extension length from the connecting sleeve, thus tightening the steel wire rope. This allows for a final tightening stroke without pulling the steel wire rope, preventing excessive stress on the rope and potential hand strain.

[0022] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] like Figures 1-3 As shown, this utility model includes a mounting frame 1. A constraint frame 2 is fixedly connected to one side of the mounting frame 1. A movable seat 3 is inserted into the constraint frame 2. Both the constraint frame 2 and the movable seat 3 are non-circular structures. An unlocking rod 4 is rotatably connected to the mounting frame 1. The unlocking rod 4 is threadedly connected to the movable seat 3. A steel wire rope 5 is fixedly connected to the outer end of the movable seat 3. A locking frame 6 is provided at the other end of the mounting frame 1. A conical cavity 7 is opened in the locking frame 6. A collar 8 is provided in the conical cavity 7. A spherical groove is opened on the side of the collar 8. A friction ball 9 that can be partially displaced in the spherical groove is provided in the spherical groove. A movable groove 10 is opened on the side of the locking frame 6. A lever 11 that is fixedly connected to the collar 8 is provided at the movable groove 10. An end cap 12 is provided at the end of the locking frame 6. A spring 13 is provided on the end cap 12. Both the locking frame 6 and the end cap 12 have through holes through which the steel wire rope 5 can pass.

[0028] Example 1: The mounting frame 1 includes an arc-shaped section in the middle and horizontal sections at both ends of the arc-shaped section. The constraint frame 2 and the locking frame 6 are respectively set on the two horizontal sections. The end of the wire rope 5 is provided with a connector with a tapered structure, and the end of the unlocking rod 4 is fixedly connected with a handle.

[0029] Specifically: The mounting bracket 1 features an arc-shaped structure in the middle to better fit fixed foundations such as circular columns. The two horizontal sections facilitate the installation of the constraint frame 2 and the locking frame 6. The connector at the end of the wire rope 5 allows for easy insertion into the locking frame 6. A handle is provided at the end of the locking rod 4 for easy rotation by the user.

[0030] Example 2: A limiting groove is provided in the constraint frame 2, and a limiting block located in the limiting groove is fixedly connected to the side of the movable seat 3. A connecting sleeve 14 is fixedly connected to one end of the mounting bracket 1, and the locking frame 6 is threadedly connected to the connecting sleeve 14.

[0031] Specifically: The limiting groove, in conjunction with the limiting block, constrains the movable seat 3, preventing it from shifting in other directions and also preventing it from completely detaching from the constraint frame 2. The connecting sleeve 14 connects the locking frame 6 to the mounting bracket 1. When needed, such as when pulling the wire rope 5 for locking, the locking frame 6 can be rotated to adjust its extension length from the connecting sleeve 14, thus tightening the wire rope 5. This allows for the final stage of tightening without pulling the wire rope 5, preventing excessive stress on the wire rope and hand discomfort.

[0032] Example 3: There are at least three friction balls 9 evenly arranged on the collar 8. Movable grooves 10 are provided on both sides of the locking frame 6, and rough texture is provided on the outer side of the lever block 11.

[0033] Specifically, multiple friction balls 9 exert frictional constraints on the wire rope 5 from different directions, making the lock more secure when tightened. Two movable grooves 10, in conjunction with two levers 11, provide convenience for the user to rotate the lock frame 6. The rough texture on the levers 11 effectively increases the friction when the user holds the lock, preventing slippage.

[0034] The working principle of this utility model is as follows: S1. When in use, pass the steel wire rope 5 around the part to be locked, then insert it into the locking frame 6. Pull the steel wire rope 5 out from the other end of the locking frame 6 and tighten it. The steel wire rope 5 is automatically locked by the locking buckle, thereby fixing the relevant parts of the display screen. S2. When it is necessary to disassemble the lock, rotate the unlocking lever 4. Under the constraint of the constraint frame 2, the unlocking lever 4 drives the moving seat 3 to move. The movement of the moving seat 3 causes one end of the wire rope 5 to loosen partially, allowing the collar 8 to gain some movement space. Then, hold the relevant display screen structure and move the toggle block 11 to move the collar 8. The friction ball 9 loses the constraint of the conical cavity 7 and moves partially outward in the spherical groove, unlocking the wire rope 5. Then, the wire rope 5 can be pulled to pull it out of the lock frame 6, thus disassembling the lock.

[0035] Compared with the prior art, the present invention has the following advantages: 1. This LED display screen features a quick-connect locking mechanism. Through a structure including a constraint frame 2, a movable base 3, an unlocking rod 4, a steel wire rope 5, a locking frame 6, and a conical cavity 7, when the lock needs to be disassembled, rotating the unlocking rod 4 causes the movable base 3 to shift under the constraint of the constraint frame 2. This movement of the movable base 3 loosens one end of the steel wire rope 5, allowing the collar 8 some room to move. Then, by holding the relevant display screen structure and moving the lever 11, the collar 8 moves, and the friction ball 9 loses the constraint of the conical cavity 7, shifting outward within the spherical groove, thus unlocking the steel wire rope 5. The steel wire rope 5 can then be pulled out of the locking frame 6, achieving lock disassembly. Even if the steel wire rope is tightened during use, it can be loosened by rotating the unlocking rod 14, making disassembly more convenient.

[0036] 2. The LED display screen features a quick-connect locking mechanism. The limiting groove, in conjunction with the limiting block, constrains the movable seat 3, preventing displacement in other directions and avoiding complete detachment from the constraint frame 2. The locking frame 6 is connected to the mounting bracket 1 using the connecting sleeve 14. When needed, such as when tightening the steel wire rope 5, the locking frame 6 can be rotated to adjust its extension length from the connecting sleeve 14, thus tightening the steel wire rope 5. This allows for a final tightening stroke without pulling the steel wire rope 5, preventing excessive strain on the hand.
