Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, in particular to an LED display screen box assembly lock. Background Art

[0002] LED display screens are made up of multiple identical unit boxes and are used to display various information such as text, images, and videos. With the changes in site environments and people's growing demand for visual entertainment, the application scenarios of LED display screens are constantly improving, and the demand for multi-angle curved display screens has basically become normalized.

[0003] To achieve flexible angle adjustment for LED displays, current technology primarily relies on arc locks and angle blocks. The angle block connection solution offers greater freedom in angle selection. By replacing angle blocks with different angles, the angle between adjacent cabinets can be easily changed to meet diverse angle requirements. However, replacing angle blocks is a relatively cumbersome process, requiring multiple steps and time.

[0004] The angle of traditional arc locks is fixed at the beginning of the design and cannot be changed at will. This means that once the angle of the arc lock is set, it can only be spliced ​​within the set angle range and the angle cannot be adjusted beyond this range. In addition, the angle accuracy formed by the arc lock may not be high enough to meet high-precision requirements. At the same time, when dealing with internal and external arcs with a large angle range, the arc lock often has difficulty taking into account both, which limits its application scenarios. Therefore, there is a need for an assembly lock that can easily adjust the angle and has a large angle range. Utility Model Content

[0030] The utility model provides a LED display box assembly lock, such as Figure 1 and Figure 2 As shown, it includes a first component 1 and a second component 2 respectively provided on two adjacent boxes and connected to each other. The first component 1 includes a lock column 11 and a lock ring 12. The lock column 11 passes through the lock ring 12. The lock ring 12 is provided with a plurality of lock holes 121. The inclination angle between each lock hole 121 and the lock column 11 is different.

[0031] The second component 2 includes a lock buckle 21 that matches and connects with the lock hole 121 .

[0032] The present invention connects two adjacent LED display boxes through a first component 1 and a second component 2. The locking ring 12 of the first component 1 has multiple locking holes 121 with different inclination angles. The locking buckle 21 of the second component 2 can be selectively connected to different locking holes 121, thereby realizing a variety of splicing angles between the two assembled boxes. At the same time, the locking column 11 passes through the locking ring 12. The user rotates the locking ring 12 to a preset angle through the locking column 11 to achieve angle adjustment between the assembled boxes. The operation is simple and quick.

[0033] Specifically, in order to achieve the angle adjustment between the LED display boxes, the utility model sets a first component 1 and a second component 2 at the opposite ends of the box. Figure 1 , Figure 1 The diagram in the figure shows the structure of two boxes connected together. Figure 1 It can be seen that box A is spliced ​​with the second component 2 of box B through the first component 1.

[0034] Furthermore, the first component 1 includes a locking post 11 and a locking ring 12. The locking ring 12 is provided with multiple locking holes 121 with different inclination angles. The locking holes 121 of box A are connected to the locking buckles 21 of box B, thereby firmly connecting box A and box B. At the same time, the locking post 11 passes through the locking ring 12, allowing the locking ring 12 to rotate with the rotation of the locking post 11. The user can select the locking hole 121 with the desired inclination angle and connect it to the locking buckle 21 by rotating the locking post 11. This method is simple and quick to operate, providing user convenience.

[0035] It should be noted that, because the purpose of the present invention is to select different lock holes 121 for connection with the lock buckle 21, and to achieve splicing of two boxes at different angles, in order to ensure the stability of the connection between the two boxes, the plane where the lock hole 121 is located and the plane where the lock buckle 21 is located need to fit together. Therefore, the inclination angle between each lock hole 121 and the lock column 11 is different, which means that the plane where each lock hole 121 is located is not consistent with the inclination angle of the axis of the lock column 11, and each lock hole 121 is perpendicular to the plane where it is located. Not all lock holes 121 are in the same vertical plane, and the opening direction of the lock hole 121 is inclined at a different angle to the vertical plane. At the same time, to ensure the connection between the first component 1 and the second component 2, the lock column 11 must be in vertical contact with the box.

[0036] In one embodiment, the locking ring 12 includes an inner tube disposed in the center and an outer frame disposed outside the inner tube. The inner tube is connected to the outer frame via a fixing frame. A locking sleeve 13 is disposed at one end of the locking column 11 and the other end passes through the inner tube.

[0037] In this embodiment, the lock ring 12 consists of an inner tube and an outer frame. The inner tube is located at the center of the lock ring 12 and is a core component of the lock ring 12 structure. It provides support and serves as a channel for the movement of the lock column 11. The rotation of the entire lock ring 12 is based on the central axis of the inner tube. The outer frame is located outside the inner tube and together with the inner tube, it forms the main structure of the lock ring 12.

[0038] A locking sleeve 13 is provided at one end of the locking post 11, and the other end extends through the inner tube. The locking sleeve 13 facilitates the user to rotate the locking post 11, which drives the inner tube to rotate, and the locking hole 121 also rotates with the outer frame and inner tube. The fixing bracket is used to connect the inner tube and outer frame to ensure the relative position between them is stable.

[0039] In one embodiment, if Figure 3 and Figure 4 As shown, the outer frame includes a plurality of interconnected inclined surfaces 122 . The inclined angles between each inclined surface 122 and the locking column 11 are different, and the locking hole 121 is provided on the inclined surface 122 .

[0040] The inclined surface 122 is a surface with a certain inclination angle relative to the vertical plane. The outer frame is composed of multiple such inclined surfaces 122 connected to each other, forming a complex and multi-faceted structure. Each inclined surface 122 is connected to each other and is connected to the inner tube through a fixing frame.

[0041] from Figure 3 The lock hole 121 is formed by forming an opening on the inclined surface 122, which is connected to the lock buckle 21 of the second component 2. The locking mechanism between the lock buckle 21 and the lock hole 121 can be the engagement of a hook and a protrusion, the compression of a spring, etc. By designing the inclined surface 122 in different ways, when the lock hole 121 on the inclined surface 122 is connected to the lock buckle 21, the two boxes can be spliced ​​at a corresponding angle.

[0042] For example, if the angle between a certain inclined surface 122 and the vertical plane on which the lock cylinder 11 is located is 5° and the opening is facing downward, that is, when viewed from the thickness direction of the box body, the inclined surface 122 is inclined 5° from top to bottom in a direction away from the lock cylinder 11. When the lock hole 121 on the inclined surface 122 is connected to the lock buckle 21, the internal angle between the two boxes is 175°.

[0043] In one embodiment, referring to Figure 4 A limiting block 111 is provided at one end of the lock column 11 away from the lock sleeve 13 , and a first limiting groove 123 matching the limiting block 111 is provided at one end of the inner tube away from the lock sleeve 13 .

[0044] from Figure 4 It can be seen that the limit block 111 is a protrusion or projection on the lock column 11, and its shape and size match the first limit groove 123 on the inner tube. The function of the limit block 111 is to limit the movement range of the lock column 11 in the inner tube and prevent the lock column 11 from having unnecessary movement with the lock ring 12 when not needed.

[0045] A first limiting groove 123 is provided at the edge of the inner tube facing away from the locking sleeve 13. The function of the first limiting groove 123 is to receive and accommodate the limiting block 111, thereby limiting the movement of the lock cylinder 11 within the inner tube and ensuring that the lock cylinder 11 can properly engage the lock ring 12 when needed. When the user lifts the lock cylinder 11 upward, the limiting block 111 will be trapped in the first limiting groove 123, thereby limiting the movement between the lock cylinder 11 and the lock ring 12. When the user rotates the lock cylinder 11, the lock ring 12 is also driven. Compared to traditional arc locks, the present utility model uses the first limiting groove 123 in conjunction with the limiting block 111 to drive the lock ring 12, which is simple to operate.

[0046] In one embodiment, a stopper 112 is provided at one end of the lock cylinder 11 away from the lock sleeve 13. The connection between the first assembly 1 and the housing requires the stopper 112, which prevents the lock cylinder 11 from completely separating from the housing while allowing the lock cylinder 11 to rotate freely within the housing.

[0047] In one embodiment, if Figure 5 As shown, the box body is provided with a lock slot 3 for accommodating the lock ring 12 , and the lock slot 3 includes an upper shell 31 and a lower shell 32 provided on the upper and lower sides of the lock ring 12 .

[0048] The lock slot 3 consists of an upper shell 31 and a lower shell 32, which together provide a space for the lock ring 12. The shape and size of the lock slot 3 must match the lock ring 12 to ensure that the lock ring 12 can rotate freely within it. The lock ring 12 is located within the lock slot 3. The lock post 11 connects the lock ring 12 and the upper and lower shells of the lock slot 3 in series, allowing the lock ring 12 to rotate within the lock slot 3 and move along the length of the lock post 11, while also restricting the lock ring 12 from moving left and right within the lock slot 3. This helps prevent the lock ring 12 from moving unnecessarily when not needed, thereby improving the stability and safety of the first assembly 1.

[0049] In one embodiment, if Figure 6 As shown, the upper and lower housings 31 and 32 each have a post hole for accommodating the lock post 11. One end of the lock post 11 is fitted with a locking sleeve 13, while the other end passes through the post hole in the upper housing 31, the inner tube, and the post hole in the lower housing 32. The lock post 11 passes through the post holes in the upper and lower housings 31 and 32, connecting the lock ring 12 to the upper and lower parts of the housing. It's important to note that the post holes in the upper and lower housings 31 and 32 must be precisely aligned and sized to match the lock post 11. This ensures that the lock post 11 can pass smoothly through the post holes and remains stable when needed.

[0050] In one embodiment, the column hole of the lower shell 32 is a lower column hole 321, and a second limiting groove 322 matching the limiting block 111 is provided on the side of the lower shell 32 facing away from the limiting portion 112. The second limiting groove 322 is provided at the end of the lower column hole 321 facing the locking ring 12.

[0051] The shape and size of the second limiting groove 322 must match the limiting block 111 on the lock post 11 to ensure that the limiting block 111 can be accurately engaged. Under the action of gravity, the limiting block 111 on the lock post 11 will be stuck in the second limiting groove 322, locking the lock post 11 to the lower housing 32 and preventing it from rotating. To rotate the lock, the lock sleeve 13 is lifted, and the limiting block 111 will move out of the second limiting groove 322. The lock post 11 is free from the restraint of the lower housing 32, and the user can rotate the lock sleeve 13 and lock post 11. Because the lock post 11 is connected to the lock ring 12, rotating the lock post 11 will cause the lock ring 12 to rotate within the lock groove 3, thereby unlocking or locking the lock. After completing the unlocking or locking operation, the user can release the lock sleeve 13. Under the action of gravity, the limiting block 111 will reengage the second limiting groove 322, securing the lock post 11 within the lower housing 32, and the lock will return to the locked state.

[0052] In one embodiment, if Figure 6As shown, the upper housing 31 has an upper post hole 311. A dial gauge 312 is provided on the side of the upper housing 31 facing the lock sleeve 13. The dial gauge 312 is located outside the upper post hole 311 and is arranged in a circular shape with the upper post hole 311 as the center. The dial gauge 312 provides a user with a reference for the rotation angle of the lock post 11, allowing the user to accurately control the unlocking or locking state of the lock.

[0053] The lock sleeve 13 is located at one end of the lock cylinder 11 and is exposed outside the lock slot 3. The user rotates the lock cylinder 11 by operating the lock sleeve 13. Because the degree scale 312 is located on the side of the upper housing 31 facing the lock sleeve 13, the user can easily observe the scale on the degree scale 312 while operating the lock sleeve 13, thereby accurately controlling the rotation angle of the lock cylinder 11.

[0054] In one embodiment, the locking sleeve 13 has two opposite ends respectively provided with a first end 131 and a second end 132 protruding outwards. The first end 131 has an observation hole disposed above the degree scale 312 .

[0055] The lock sleeve 13 is an operating component on the lock cylinder 11, typically located at one end of the lock cylinder 11 and exposed outside the lock slot 3. The lock sleeve 13 has a first end 131 and a second end 132 at opposite ends, respectively, which protrude outward, making the lock sleeve 13 easier for the user to hold and operate.

[0056] The viewing hole is located above the degree scale 312 so that the user can directly observe the scale on the degree scale 312 through the viewing hole. In this way, when the user operates the lock sleeve 13, the user can conveniently observe the rotation angle of the lock cylinder 11, thereby more accurately controlling the unlocking or locking state of the lock.

[0057] The process of using the present invention is as follows: first, the user lifts the lock sleeve 13, and the limit block 111 of the lock column 11 opens the second limit groove 322, but is still stuck in the first limit groove 123. At this time, the lock column 11 can drive the lock ring 12 to rotate, thereby realizing the unlocking or locking operation.

[0058] The user observes the scale on the degree meter 312 through the viewing hole on the lock sleeve 13 to determine the current rotation angle of the lock cylinder 11. Then, the user rotates the lock sleeve 13 to a predetermined angle as needed, and the inclined surface 122 on the lock cylinder 11 corresponding to the predetermined angle is rotated to a position where the lock slot 3 faces the second component 2.

[0059] Then, the user puts down the lock sleeve 13, and under the action of gravity, the limiting block 111 will be locked into the second limiting groove 322 again, fixing the lock cylinder 11 in the lower shell 32, and the lock returns to the locked state.

[0060] Finally, align the lock hole 121 of the first component 1 with the lock buckle 21 of the second component 2 to connect them, so that the two boxes can be spliced ​​at different angles.

[0061] The above embodiments are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
