Description

Technical Field

[0001] This disclosure relates to the field of display screen technology, and in particular to a display screen splicing device. Background Technology

[0002] With the rapid development of the LED industry, LED display rental has become extremely popular. Among them, splicing screens are large screens composed of multiple LED displays arranged in a matrix. They typically use cabinets to house the displays, and then connect adjacent cabinets to form a large screen. During the installation of rented products, workers need to quickly assemble multiple LED cabinets into a display for use, and then quickly disassemble the assembled display after the rental period. The assembly process requires locking devices, but traditional locking devices for securing the cabinets are cumbersome and complex to operate, completely failing to meet the efficiency and simplicity requirements of rental applications. Utility Model Content

[0037] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure. In the description of the embodiments of this disclosure, unless otherwise stated, " / " means "or", for example, A / B can mean A or B; "and / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone.

[0038] The terms "first" and "second" are used for descriptive purposes only and should not be construed as implying relative importance or implicitly indicating the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "multiple" means two or more.

[0039] In the installation process of existing rental products, most use ratchet quick-installation lock structures. Before locking, the lock head must be in a fixed position to engage the locking pin and latch, and then the handle must be rotated to lock. The disassembly and unlocking process after rental also requires releasing the handle to a fixed position and manually pulling out the locking pin to complete the unlocking action. In other words, locking and unlocking rental products require precise alignment of the lock head and latch, and installation requires one or more people, making the process cumbersome and inefficient. To achieve rapid installation and disassembly of rental products, reduce manpower, and improve operational convenience and installation efficiency, this disclosure proposes the following solutions, specifically including:

[0040] like Figures 1-6 As shown, this disclosure provides a display splicing device, including:

[0041] Multiple display screen housings 1, each display screen housing 1 including a first connecting beam 11 and a second connecting beam 12 arranged opposite to each other;

[0042] The quick-lock assembly 2 includes a lock plate 21 and a lock body 22; in any two adjacent display screen housings 1, the lock plate 21 is fixed to the first connecting beam 11 of one display screen housing 1, and the lock body 22 is fixed to the second connecting beam 12 of the other display screen housing 1.

[0043] The lock body 22 includes a locking pin 221 and a lock head 222 fixedly connected to one end of the locking pin 221. The first connecting beam 11 includes a first through hole 111 through which the locking pin 221 and the lock head 222 pass. The second connecting beam 12 includes a second through hole 121 through which the locking pin 221 and the lock head 222 pass.

[0044] The locking piece 21 includes an opening 211, which includes a first partition 2111, a second partition 2112, and a third partition 2113. The second partition 2112 and the third partition 2113 are located on both sides of the first partition 2111.

[0045] It should be noted that, as Figures 1-5 As shown, the above-mentioned display splicing device includes multiple display cabinets 1 for supporting multiple display screens. After splicing and fixing the multiple display cabinets, a large screen composed of multiple display screens can be obtained. Each display cabinet 1 includes a first connecting beam 11 and a second connecting beam 12 arranged opposite to each other. The first connecting beam 11 of one display cabinet 1 is spliced ​​and fixed with the second connecting beam 12 of another display cabinet 1. The display splicing device also includes a quick-lock assembly 2, which includes a locking plate 21 and a locking body 22. In any two adjacent display cabinets 1, the first connecting beam 11 of one display cabinet 1 is used to install the locking plate 21, and the second connecting beam 12 of the other display cabinet 1 is used to install the locking body 22. The locking plate 21 and the locking body 22 cooperate to achieve splicing and fixing of the two adjacent display cabinets 1. The lock body 22 includes a locking pin 221 and a lock head 222 fixedly connected to one end of the locking pin 221. The first connecting beam 11 includes a first through hole 111 at the position corresponding to the mounting of the lock plate 21, and the second connecting beam 12 includes a second through hole 121 at the position corresponding to the mounting of the lock body 22. Both the first through hole 111 and the second through hole 121 allow the locking pin 221 and the lock head 222 to pass through, so that the lock head 222 can reach the position to lock or unlock with the lock plate 21. The lock plate 21 includes an opening 211, which includes a first partition 2111 and a second partition 2112 and a third partition 2113 located on both sides of the first partition 2111.

[0046] This disclosure rationally designs the shape of the opening 211 of the lock plate 21 according to the shape of the lock head 222, so that the opening 211 has a certain margin for the lock head 222 to pass through. Thus, during the installation of the rental product, the locking and unlocking of the display screen cabinet 1 can be quickly achieved without precise alignment of the lock head 222 and the opening 211 of the lock plate 21. This improves the convenience of operation and installation efficiency, and enables single-person, one-handed operation, reducing manpower.

[0047] like Figures 3-5As shown, the sum of the dimensions of the first partition 2111, the second partition 2112, and the third partition 2113 along the first direction is greater than or equal to the length of the lock head 222; the dimension of the first partition 2111 along the second direction is greater than the width of the lock head 222 and less than the length of the lock head 222; the maximum dimension of the second partition 2112 and the third partition 2113 along the second direction is greater than the dimension of the first partition 2111 along the second direction, so that the lock head 222 can deflect at a preset angle relative to the first direction in the opening 211;

[0048] The first direction is the direction determined by the line connecting the geometric centers of the first partition 2111, the second partition 2112, and the third partition 2113, and the second direction is perpendicular to the first direction.

[0049] Specifically, in order to achieve locking and unlocking without precise alignment of the lock plate 21 and the lock head 222, the opening 211 of the lock plate 21 and the lock head 222 of this disclosure must at least satisfy the following relationship:

[0050] (1) The sum of the dimensions of the first partition 2111, the second partition 2112 and the third partition 2113 along the first direction is greater than or equal to the length of the lock head 222. This setting ensures that the lock head 222 can pass smoothly through the opening 211 of the lock plate 21 and cooperate with the side of the lock plate 21 away from the lock body 22, so as to lock the lock head 222 and the lock plate 21. It also ensures that the lock head 222 can smoothly disengage from the lock plate 21 when unlocking.

[0051] (2) The dimension of the first partition 2111 along the second direction is greater than the width dimension of the lock head 222 and less than the length dimension of the lock head 222. This setting ensures that the lock head 222 can pass smoothly through the opening 211 of the lock plate 21. Secondly, it ensures that after the lock head 222 passes through the opening 211 of the lock plate 21 and rotates at a certain angle, it can lock with the side of the lock plate 21 away from the lock body 22, and will not cause the lock head 222 to detach from the opening 211 of the lock plate 21.

[0052] (3) The maximum dimensions of the second partition 2112 and the third partition 2113 along the second direction are greater than the dimension of the first partition 2111 along the second direction. With this configuration, the lock head 222 does not need to be precisely aligned with the opening 211 of the lock plate 21. When the lock head 222 is deflected by a preset angle relative to the first direction, it can still pass through the opening 211 of the lock plate 21, thereby locking the lock head 222 and the lock plate 21. Similarly, when unlocking is required, the lock head 222 does not need to be precisely aligned with the opening 211 of the lock plate 21. When rotated to a preset angle with the first direction, the lock head 222 and the lock plate 21 can also be unlocked. Here, the first direction is the direction determined by the line connecting the geometric centers of the first partition 2111, the second partition 2112, and the third partition 2113, and the second direction is perpendicular to the first direction.

[0053] It should be noted that during the locking process where the lock head 222 passes through the opening 211 of the lock plate 21 and rotates at a certain angle, the rotation angle is usually greater than the aforementioned preset angle to ensure that the lock head 222 does not disengage from the opening 211 of the lock plate 21. Preferably, the optimal locking state is achieved when the length direction of the lock head 222 is rotated to be perpendicular to the first direction. That is, the length direction of the lock head 222 forms a 90° angle with the length direction of the opening 211. Figures 3-5 As shown, in one possible implementation, the second partition 2112 and the third partition 2113 are symmetrical about the first partition 2111. Since the shape of the opening 211 matches the shape of the lock head 222, the shape of the opening 211 is also symmetrical when the outer contour of the lock head 222 is axially symmetrical. It can be understood that when the outer contour of the lock head 222 is not axially symmetrical, the shapes of the second partition 2112 and the third partition 2113 of the opening 211 can be symmetrical or not.

[0054] Continue to refer to Figures 3-5 The preset angle is 0°-20°, such as 0°, 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, etc., with no specific limitation. Figure 3 As shown, the angle between the length direction of the lock head 222 and the first direction is 0°, allowing the lock head 222 to pass smoothly through or disengage from the opening 211 of the lock plate 21. Figure 4 As shown, when lock head 222 is opposite Figure 3 After rotating the position counterclockwise by a certain angle, the length direction of the lock head 222 forms an angle with the first direction, allowing the lock head 222 to pass smoothly through or disengage from the opening 211 of the lock plate 21. For example... Figure 5 As shown, when lock head 222 is opposite Figure 3 After the position is rotated clockwise by a certain angle, the length direction of the lock head 222 also has an angle with the first direction. At this time, the lock head 222 can be smoothly passed through or disengaged from the opening 211 of the lock plate 21.

[0055] like Figure 6 As shown, the lock body 22 also includes a lock seat 223, a first sleeve 224, a second sleeve 225, and an elastic element 226;

[0056] The lock seat 223 is fixedly installed on the second connecting beam 12 of the display screen housing 1. One end of the first sleeve 224 is fixedly connected to the lock seat 223, and the other end passes through the second through hole 121.

[0057] The first sleeve 224 is sleeved on the outside of the second sleeve 225 and is slidably connected to the second sleeve 225;

[0058] Locking pin 221 passes through the first sleeve 224 and the second sleeve 225 and is threadedly connected to the second sleeve 225;

[0059] A first limiting part 2241 is provided inside the first sleeve 224 near the second connecting beam 12, and a second limiting part 2251 is provided on the side of the second sleeve 225 near the second connecting beam 12. An elastic element 226 is sleeved inside the first sleeve 224, with one end connected to the first limiting part 2241 and the other end connected to the second limiting part 2251. It is used to provide a force for the second sleeve 225 to disengage from the first sleeve 224 when the lock head 222 is locked with the lock plate 21.

[0060] Specifically, refer to Figure 6 , combined Figure 1 The first sleeve 224 includes a first connecting part 2242 and a second connecting part 2243 that are connected to each other. The first connecting part 2242 is located at one end of the second connecting part 2243 near the second connecting beam 12. The outer diameter of the first connecting part 2242 and the second connecting part 2243 are the same, and the inner diameter of the first connecting part 2242 is smaller than the inner diameter of the second connecting part 2243, so as to form a first stepped surface, i.e., a first limiting part 2241, at the connection between the first connecting part 2242 and the second connecting part 2243. The second sleeve 225 includes a third connecting portion 2252 and a fourth connecting portion 2253 connected to each other. The third connecting portion 2252 is located at the end of the fourth connecting portion 2253 near the second connecting beam 12. The inner diameters of the third connecting portion 2252 and the fourth connecting portion 2253 are the same, while the outer diameter of the third connecting portion 2252 is smaller than the inner diameter of the fourth connecting portion 2253, so as to form a second stepped surface, i.e., a second limiting portion 2251, at the connection between the third connecting portion 2252 and the fourth connecting portion 2253. One end of the elastic member 226 is connected to the first stepped surface, and the other end is connected to the second stepped surface. The locking pin 221 passes through the first sleeve 224 and the second sleeve 225 and is threadedly connected to the second sleeve 225. When the lock head 222 is locked with the lock plate 21, the elastic element 226 is in a compressed state, providing the second sleeve 225 with a force to disengage from the first sleeve 224. This allows the lock head 222 to be automatically disengaged from the lock plate 21 by the second sleeve 225 when it rotates to the corresponding position during the subsequent unlocking process. In other words, the lock head 222 can be automatically released without manual pulling, which effectively solves the problem of precise alignment required during operation. This truly enables single-person, single-hand operation, improves operational efficiency, and enhances product competitiveness.

[0061] Continue to refer to Figure 6The lock body 22 also includes a guide block 227. The outer wall of the second sleeve 225 is provided with a guide groove 2254 extending along a third direction. The guide block 227 passes through the side wall of the lock seat 223 and the first sleeve 224 and is slidably connected to the guide groove 2254. The third direction is the axial direction of the second sleeve 225.

[0062] Through the cooperation of guide block 227 and guide groove 2254, the guide block 227 moves up and down in guide groove 2254 during the sliding process of the first sleeve 224 and the second sleeve 225. This guides the first sleeve 224 and the second sleeve 225 during the sliding process, and also improves the overall structural stability of the lock body 22, preventing internal structural shaking during operation. It should be noted that guide block 227 can be an M3×6 countersunk screw.

[0063] Continue to refer to Figure 6 The lock body 22 also includes a ratchet 228, a button 229, and a handle 230;

[0064] The handle 230 is located at the end of the second sleeve 225 away from the lock seat 223 and is fixedly connected to the lock pin 221; the ratchet 228 is sleeved at the end of the second sleeve 225 away from the lock seat 223.

[0065] The handle 230 includes a first mounting part 2301, and a button 229 is rotatably mounted on the first mounting part 2301. The button 229 has a first position and a second position. When the button 229 is in the first position, the button 229 is engaged with the ratchet 228; when the button 229 is in the second position, the button 229 is disengaged from the ratchet 228.

[0066] Specifically, such as Figure 6 As shown, when the handle 230 is turned to lock, the handle 230 drives the locking pin 221 to rotate. The second sleeve 225 is fixedly connected to the handle 230. During the rotation of the locking pin 221, it engages with the internal thread of the second sleeve 225 to achieve the final locking state of the lock head 222 and the locking plate 21. To prevent the handle 230 from rotating back, this embodiment of the disclosure provides a button 229. During the rotation of the handle 230, the button 229 is always engaged with the ratchet 228. After locking, the button 229 and the ratchet 228 cooperate to prevent the handle 230 from rotating back. At this time, the button 229 is in the first position. When unlocking is required, the button 229 can be pressed. At this time, the button 229 disengages from the ratchet 228, and the handle 230 can be rotated in the opposite direction. After rotating to the correct position, it automatically rebounds to unlock. At this time, the button 229 is in the second position. It should be noted that the handle 230 and the locking pin 221 can be fixedly connected by countersunk screws.

[0067] Continue to refer to Figure 6The button 229 includes a pressing part 2291 and a stop part 2292 connected to each other, and the stop part 2292 includes a first through hole 2293;

[0068] The first mounting part 2301 passes through the first through hole 2293 and is rotatably connected to the stop part 2292. The stop part 2292 engages with the convex teeth of the ratchet 228 and is used to stop the handle 230 when the lock head 222 is locked with the lock plate 21.

[0069] The pressing part 2291 is used to switch the button 229 between the first position and the second position.

[0070] Specifically, such as Figure 6 As shown, when the pressing part 2291 of button 229 is not pressed, button 229 is in the first position. At this time, the stop part 2292 engages with the convex teeth of ratchet 228 to lock handle 230. When the pressing part 2291 of button 229 is pressed, button 229 is in the second position. At this time, the stop part 2292 disengages from the convex teeth of ratchet 228 to release handle 230 for easy unlocking.

[0071] Continue to refer to Figure 6 The stop portion 2292 also includes a second through hole 2294, inside which a torsion spring 2295 is disposed. One end of the torsion spring 2295 is connected to the wall of the second through hole 2294, and the other end is connected to the inner wall of the handle 230, for providing a force for the button 230 to switch from the second position to the first position. By providing the torsion spring 2295, after the pressing portion 2291 is released, the button 229 can automatically return to the state of engaging with the ratchet 228, preventing the handle 230 from rotating freely, and improving installation accuracy and stability.

[0072] Continue to refer to Figure 6 The handle 230 has a clearance groove 2302 on its side wall, and the stop part 2292 passes through the clearance groove 2302 and is rotatably connected to the first mounting part 2301. It can be understood that the clearance groove 2302 has space for the button 229 to move, so as to smoothly realize the pressing and restoring of the pressing part 2291.
