[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0038] Please refer to Figure 1 This is an exploded three-dimensional structural diagram of a display screen lock provided in an embodiment of the present utility model. The display screen lock includes a locking rod 10, two locking grooves 20, and a handle 30.

[0039] Please combine Figure 2-4 The display screen lock is used to connect with the locking pin 40, wherein the two locking slots 20 are respectively fixedly connected to the two ends of the locking rod 10; the handle 30 is fixedly connected to the middle position of the locking rod 10, and can drive the locking rod 10 to switch between the locked position and the unlocked position; wherein, when the locking rod 10 rotates to the locked position, the locking slot 20 can be locked and connected with the locking pin 40, at which time the free end 310 of the handle 30 protrudes from the plane where the locking pin 40 and the locking rod 10 are located; when the locking rod 10 rotates to the unlocked position, the locking pin 40 can be disengaged from the locking slot 20.

[0040] Here, the locking rod 10 and the two locking slots 20 at its ends are generally made of metal and are connected by an integral structure or by welding. Alternatively, they can be connected in a sleeve-like manner as shown in the figure, but they cannot rotate relative to each other; instead, they can rotate together. This is mainly achieved by rotating the locking rod 10, which in turn drives the locking slots 20 to rotate. Specifically, the handle 30 is fixedly connected to the middle position of the locking rod 10. Applying a certain rotational force to the handle 30 can drive the locking rod 10 to rotate, further driving the locking rod 10 to rotate the locking slots 20 at both ends. The rotation of the locking rod 10 has a certain amplitude, defined here as the locked position and the unlocked position, meaning the locking rod 10 can move between the locked position and the unlocked position. When the locking lever 10 is rotated between the locked and unlocked positions under the action of the handle 30, the connection between the locking groove 20 and the locking pin 40 changes accordingly. Specifically, when the locking lever 10 is rotated to the locked position, the locking groove 20 can be locked to the locking pin 40, thus completing the locking connection between the two LED displays. When the locking lever 10 is rotated to the unlocked position, the locking pin 40 can disengage from the locking groove 20, thus completing the separation between the two LED displays.

[0041] In this embodiment of the utility model, by rotating the handle 30 once, the locking rod 10 is driven to switch between the locked position and the unlocked position, thereby enabling the locking grooves 20 at both ends of the locking rod 10 to simultaneously lock or unlock with the corresponding two locking pins 40, which greatly speeds up the LED display splicing speed.

[0042] Additionally, the handle 30 includes a free end 310 and a connecting end 320. The connecting end 320 is inserted into the locking rod 10 to form a fixed connection. The free end 310 is the end away from the locking rod 10 and is used for hand gripping and applying rotational force. The display screen lock is applied to an LED display screen. When the locking rod 10 is rotated to the locked position, that is, when two adjacent LED display screens are connected together, the free end 310 of the handle 30 protrudes from the plane where the locking post 40 and the locking rod 10 are located. In other words, the free end 310 of the handle 30 protrudes from the plane where the LED display screen is located. In a preferred embodiment, the handle 30 and the plane where the LED display screen is located form a 30-degree angle. At this time, the handle 30 has a certain gripping space, which facilitates the handling and other operations of the LED display screen.

[0043] Furthermore, when the locking rod 10 is rotated to the unlocked position, the free end 310 of the handle 30 is located on the side of the locking rod 10 away from the locking post 40, and the handle 30 is entirely hidden in the plane where the locking post 40 and the locking rod 10 are located.

[0044] Specifically, when the locking rod 10 is rotated to the unlocked position, the free end 310 of the handle 30 is rotated to the side of the locking rod 10 away from the locking post 40. At this time, the handle 30 is hidden in the plane where the LED display screen is located. At this time, the two LED display screens can be separated from each other. In other words, after the LED display screens are separated from each other, the handle 30 of a single LED display screen can be attached to the frame of the LED display screen to minimize the thickness of the LED display screen frame, thereby facilitating the storage and packaging of a single LED display screen.

[0045] Furthermore, in other preferred embodiments of this utility model, the head end of the locking pin 40 is a mushroom head 410;

[0046] The lock groove 20 is provided with a large lock hole 210 and a small lock hole 220 that are interconnected. The large lock hole 210 allows the mushroom head 410 to pass through, while the diameter of the small lock hole 220 is smaller than the diameter of the mushroom head 410.

[0047] Specifically, such as Figure 4 As shown, a mushroom head 410 is provided at the end of the column of the locking pin 40. The diameter of the mushroom head 410 is larger than the outer diameter of its lower end column, thus making the locking pin 40 form a shape that is larger at the top and smaller at the bottom. Two locking holes, one large and one small, are opened on the surface of the locking groove 20. These are referred to as the large locking hole 210 and the small locking hole 220, respectively. The large locking hole 210 and the small locking hole 220 are connected to each other to form a gourd shape. The large locking hole 210 allows the mushroom head 410 to pass through, while the diameter of the small locking hole 220 is smaller than the diameter of the mushroom head 410, meaning that the mushroom head 410 cannot pass through the small locking hole 220. The mushroom head 410 is inserted into the large keyhole 210. Rotating the locking rod 10 causes the locking groove 20 to rotate, causing the pillar 40 to sink into the small keyhole 220. The mushroom head 410 is then blocked by the small keyhole 220 within the locking groove 20, thus completing the locking connection between the locking groove 20 and the locking pillar 40. When unlocking is required, simply rotate the locking rod 10 in the opposite direction to rotate the locking groove 20, causing the pillar 40 to return to the large keyhole 210, allowing the mushroom head 410 to be easily removed.

[0048] Furthermore, in other preferred embodiments of this invention, the groove wall of the lock groove 20 gradually decreases in size from the small lock hole 220 to the large lock hole 210.

[0049] Specifically, the wall thickness of the groove near the small keyhole 220 is greater than that near the large keyhole 210. That is, the groove wall of the lock groove 20 gradually increases from the large keyhole 210 to the small keyhole 220. With this design, when the mushroom head 410 switches from the large keyhole 210 to the small keyhole 220, the mushroom head 410 will move towards the handle 30 to tighten the mushroom head 410 and prevent the two LED displays from shaking after the connection is completed.

[0050] In addition, in other preferred embodiments of the present invention, the locking pin 40 includes a pin body 401 and a locking pin 402 that is perpendicularly connected to the pin body 401.

[0051] The locking groove 20 includes a first groove 201, a second groove 202, and a locking hook 203. The first groove 201 is provided on the locking hook 203 for the insertion of the column 401. The second groove 202 is located in the opening direction of the locking hook 203 for the insertion of the head end of the column 401 and the locking pin 402.

[0052] Specifically, the locking pin 402 is vertically connected to the end of the column 401 to form a cross-shaped locking pin 40; the corresponding locking groove 20 includes a locking hook 203, the middle position of the locking hook 203 is slotted to form the first groove 201, the size of the first groove 201 is large enough for the column 401 to be inserted into it, the opening direction of the locking hook 203 is the second groove 202, the size of the second groove 202 is large enough for the head end of the column 401 and the locking pin 402 to be inserted into it, and when the head end of the column 401 and the locking pin 402 are inserted into the second groove 202... Then, rotating the locking rod 10 causes the locking groove 20 to rotate, so that the column 401 passes through the first groove 201, while the locking pin 402 is blocked by the locking hooks 203 on both sides of the first groove 201 in the second groove 202, thereby completing the locking connection between the locking groove 20 and the locking pin 40. When unlocking is required, simply rotate the locking rod 10 in the opposite direction to rotate the locking groove 20, so that the column 401 comes out of the first groove 201, and the head end of the column 401 and the locking pin 402 can be easily removed from the second groove 202.

[0053] Furthermore, in other preferred embodiments of this invention, the thickness of the locking hook 203 gradually increases from the head end to the rear end.

[0054] Specifically, the thickness of the groove wall near the root of the locking hook 203 is greater than the thickness of the groove wall away from the root of the locking hook 203. That is, the thickness gradually increases from the head end to the rear end of the locking hook 203. With this design, when the head end of the column 401 and the locking pin 402 are inserted into the second groove 202 and the locking rod 10 is rotated to drive the locking groove 20 to rotate, the head end of the column 401 and the locking pin 402 will move towards the handle 30 to tighten the locking column 40 and prevent the two LED displays from shaking after the connection is completed.

[0055] Furthermore, in other preferred embodiments of the present invention, the display screen lock further includes a housing 50 and a locking mechanism 60;

[0056] The locking rod 10 and the locking groove 20 are both disposed inside the housing 50. The handle 30 passes through the housing 50 and is fixedly connected to the locking rod 10. The housing 50 is provided with a through hole 510 opposite to the locking groove 20 for the locking pin 40 to pass through.

[0057] The locking mechanism 60 includes a pusher 610, a limiting rod 620, and a spring 630. The pusher 610 and the limiting rod 620 are fixedly connected. One end of the spring 630 abuts against the limiting rod 620, and the other end of the spring 630 abuts against the housing 50.

[0058] The locking rod 10 is provided with a locking hole (not shown in the figure) for the end of the limiting rod 620 away from the spring 630 to be inserted.

[0059] Specifically, the housing 50 includes a bottom groove 501 and multiple cover plates 502 covering the bottom groove 501. The locking rod 10 and the locking groove 20 are both disposed in the bottom groove 501. A notch 503 is provided on the side wall of the bottom groove 501 for the handle 30 to pass through, so that the handle 30 can pass through the housing 50 and be fixedly connected to the locking rod 10. A through hole 510 is provided at the position opposite to the locking groove 20 in the bottom groove 501. The through hole 510 is used for the locking pin 40 to pass through and connect with the internal locking groove 20.

[0060] A base 504 for mounting the locking mechanism 60 is provided on the side of the bottom groove 501 opposite to the through hole 510. The limiting rod 620 is mounted on the base 504. The pusher 610 is fixedly connected to the side of the limiting rod 620 opposite to the base 504. The spring 630 is sleeved on the limiting rod 620. One end of the spring 630 abuts against the limiting rod 620, and the other end of the spring 630 abuts against the housing 50. By pushing the pusher 610, the limiting rod 620 can be driven to reciprocate. When the pusher 610 is pushed to overcome the elastic force of the spring 630 and slide away from the locking rod 10, the end of the limiting rod 620 away from the spring 630 can disengage from the locking hole of the locking rod 10. At this time, the lock between the locking rod 10 and the housing 50 is released, and the locking rod 10 can rotate. When the locking rod 10 rotates to a preset position, the limiting rod 620 slides towards the locking rod 10 under the push of the spring 630, so that the end of the limiting rod 620 away from the spring 630 can be inserted into the locking hole of the locking rod 10, thereby completing the lock between the locking rod 10 and the housing 50. At this time, the locking rod 10 cannot rotate.

[0061] Furthermore, in other preferred embodiments of this utility model, a positioning bead (not shown in the figure) is provided on the locking rod 10, and a first positioning hole and a second positioning hole are provided on the inner wall of the housing 50.

[0062] When the locking rod 10 is rotated to the locking position, the positioning ball is inserted into the first positioning hole;

[0063] When the locking rod 10 is rotated to the unlocked position, the positioning ball is inserted into the second positioning hole.

[0064] Here, the inner wall of the housing 50 is provided with first and second positioning holes at different positions, and the locking rod 10 is provided with corresponding positioning beads. The rotational position of the locking rod 10 within the housing 50 is marked by the positioning beads entering the positioning holes at different positions. Specifically, when the locking rod 10 rotates to the locked position, the positioning beads are inserted into the first positioning hole, and when the locking rod 10 rotates to the unlocked position, the positioning beads are inserted into the second positioning hole.

[0065] Additionally, please combine Figure 5This is a schematic diagram of the connection structure of two display screen frames provided in an embodiment of the present utility model.
