Obviously, the described embodiments are only some embodiments of the embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the embodiments of this utility model.

[0031] It should be noted that in the description of this utility model, if the terms "first" or "second" appear, they are only used for the convenience of describing different components or names, and should not be construed as indicating or implying a sequential relationship, relative importance, or implicitly specifying the number of technical features indicated. Therefore, a feature specified with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, if "and / or" appears throughout the text, it means that it includes three parallel solutions; taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B.

[0032] 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.

[0033] 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 first base plate 10, a second base plate 20, a connecting plate 30, and a locking rod 40.

[0034] Please combine Figure 2-5 The first base plate 10 and the second base plate 20 are disposed opposite to each other. The side of the second base plate 20 facing the first base plate 10 is provided with a protrusion 210, and the side of the first base plate 10 facing the second base plate 20 is provided with a groove 110 that can accommodate the protrusion 210.

[0035] The connecting plate 30 is located above the connection between the first base plate 10 and the second base plate 20, with one side connected to the first base plate 10 and the other side connected to the second base plate 20;

[0036] The locking rod 40 passes through the connecting plate 30 and is threadedly connected to the protrusion 210. The locking rod 40 is provided with an eccentric shaft 410 in the area within the connecting plate 30. The locking rod 40 drives the eccentric shaft 410 to rotate, thereby driving the second base plate 20 to move closer to or away from the first base plate 10.

[0037] Specifically, the first base plate 10 and the second base plate 20 are respectively provided with the groove 110 and the protrusion 210 on their two opposite sides. The protrusion 210 can be accommodated in the groove 110, thereby making the first base plate 10 and the second base plate 20 opposite to each other. One side of the connecting plate 30 covers the top of the first base plate 10 and is connected to it, and the other side covers the top of the second base plate 20 and is connected to it, so that the connecting plate 30 covers the top of the connection between the first base plate 10 and the second base plate 20. The end of the locking rod 40 has a thread, and the protrusion 210 of the second base plate 20 is provided with a thread. The locking rod 40 has a perforated hole, allowing its end to be inserted into the threaded hole and threadedly connected to the protrusion 210. The locking rod 40 is not of uniform diameter; instead, an eccentric shaft 410 is provided within the connecting plate 30. This eccentric shaft 410 can be considered as a partially arc-shaped protrusion on the outer periphery of the locking rod 40. When the locking rod 40 rotates, the inner wall of the perforation in the connecting plate 30 for the locking rod 40 to pass through presses against the eccentric shaft 410, causing the threaded end of the locking rod 40 to swing to a certain extent. This causes the locking rod 40 to move the second base plate 20 closer to or away from the first base plate 10. Figure 2 Move in the direction indicated by the middle arrow.

[0038] Please refer to Figure 4 , 5 When the display lock described in this embodiment of the present invention is applied to the connection of multiple display screens, one display lock is connected to the connection of four display screen frames 1. As shown in the figure, the blank area in the middle is a display screen frame that has been removed. The first base plate 10 is connected to two display screen frames 1 on one side of the joint by two locking fasteners, and the second base plate 20 is connected to the third display screen frame 1 on one side of the joint by one locking fastener. When the fourth display screen frame 1 (the blank area in the middle) needs to be removed, if the display lock described in this embodiment of the present invention is not used, due to the squeezing interference of the surrounding display screen frames 1, it is necessary to start from the outermost frame and remove them one by one until the middle frame is removed. Disassembling the frame in the blank area would be inefficient; however, when using the display screen lock of this embodiment, only the locking rod 40 needs to be rotated. The locking rod 40 drives the eccentric shaft 410 to rotate, thereby moving the second base plate 20 away from the first base plate 10, so that a certain gap appears between the first base plate 10 and the second base plate 20. That is, a certain gap appears at the joint of the display screen frame 1 connected to the first base plate 10 and the second base plate 20, thereby avoiding squeezing interference with the frame to be removed (the frame in the blank area in the middle), so that the frame in the blank area in the middle can be removed quickly, that is, screen removal in the middle.

[0039] Furthermore, in other preferred embodiments of the present invention, the end of the locking rod 40 away from the protrusion 210 is provided with a handle 420 capable of driving the locking rod 40 to rotate.

[0040] Specifically, the handle 420 is fixedly connected to the end of the locking rod 40 away from the protrusion 210. By rotating the handle 420, the locking rod 40 can be rotated, making it easier to rotate the locking rod 40.

[0041] Furthermore, in other preferred embodiments of this utility model, the connecting plate 30 is provided with a through hole 310 on the side away from the first base plate 10, and a connecting post 320 is provided in the through hole 310. The end of the connecting post 320 near the second base plate 20 is threadedly connected to the second base plate 20.

[0042] The end of the connecting post 320 away from the second base plate 20 has a gap 330 with the through hole 310.

[0043] Here, the connecting plate 30 has a plurality of through holes 310 on the edge away from the first base plate 10. Each through hole 310 is provided with a connecting post 320. The end of each connecting post 320 near the second base plate 20 is threadedly connected to the second base plate 20. The end of the connecting post 320 away from the second base plate 20 is movable within the through hole 310. That is, there is a gap 330 between the end of the connecting post 320 away from the second base plate 20 and the through hole 310. The existence of the gap 330 ensures that the second base plate 20 can reciprocate relative to the connecting plate 30.

[0044] Furthermore, in other preferred embodiments of this utility model, the second base plate 20 is provided with a bead 220 on the side facing the connecting plate 30, and the connecting plate 30 is provided with a receiving groove (not shown in the figure) on the side facing the second base plate 20 to accommodate the bead 220.

[0045] Here, the ball bearing 220 and the receiving groove are respectively provided on the contact surface of the second base plate 20 and the connecting plate 30. The receiving groove can accommodate the ball bearing 220. Specifically, the ball bearing 220 is provided on the side of the second base plate 20 facing the connecting plate 30, and the receiving groove is provided on the side of the connecting plate 30 facing the second base plate 20. When relative sliding occurs between the second base plate 20 and the connecting plate 30, the ball bearing 220 can sink into the receiving groove to provide direct feedback.

[0046] Furthermore, in other preferred embodiments of this utility model, a plurality of screws 120 are arranged along the edge of the first base plate 10 facing the second base plate 20 to detachably connect the first base plate 10 and the connecting plate 30 together.

[0047] Specifically, the multiple screws 120 pass through the first base plate 10 and are positioned at the edge facing the second base plate 20, and are connected to the connecting plate 30 above it. Alternatively, the multiple screws 120 can be considered to be arranged along the outer edge of the groove 110. This design can ensure the reliability of the connection between the first base plate 10 and the connecting plate 30, and prevent the first base plate 10 from shifting along with the locking rod 40.

[0048] Furthermore, in other preferred embodiments of this utility model, the display screen lock further includes a locking fastener 50;

[0049] The first base plate 10 is provided with two locking fasteners 50, the second base plate 20 is provided with one locking fastener 50, and the three locking fasteners 50 are respectively located at the vertices of a right triangle.

[0050] Here, the four display screen frames 1 are generally arranged in a grid pattern, as shown in the figure. The first base plate 10 covers the side of the two display screen frames 1 on the left that faces away from the display screen and is fixedly connected by two locking fasteners 50. The second base plate 20 covers the side of the display screen frame 1 on the lower right that faces away from the display screen and is fixedly connected by one locking fastener 50. The display screen frame 1 on the upper right is not fixed by locking fasteners 50 because it needs to be removed. Thus, the three locking fasteners 50 are located at the vertices of a right triangle, thereby fixing the three display screen frames 1 that do not need to be removed together to ensure the overall stability of all display screen frames.

[0051] Furthermore, in other preferred embodiments of this utility model, the locking member 50 includes:

[0052] The base 510 has a mounting cavity 5101 and a positioning hole 5102 communicating with the mounting cavity 5101. The outer surface of the base 510 is provided with a slot 5103. The base 510 is fixedly connected to the first base plate 10 or the second base plate 20. The first base plate 10 or the second base plate 20 is provided with a through hole 5104 corresponding to the positioning hole 5102.

[0053] Handle 520;

[0054] A rotary lock head 530 is rotatably installed in the mounting cavity 5101. The handle 520 is fixedly connected to the rotary lock head 530 so that the handle 520 is rotatably installed relative to the base 510. The rotary lock head 530 is also provided with a bayonet 5301, which is correspondingly provided with the positioning hole 5102.

[0055] A locking lock 540 is installed on the handle 520. The locking lock 540 is provided with a locking head 5401 that cooperates with the locking slot 5103.

[0056] Specifically, the base 510 has an arc-shaped outer surface, and the mounting cavity 5101 at its center is a through-hole circular inner hole. The positioning hole 5102 of the base 510 is located at the bottom of the base 510. The base 510 is fixedly connected to the first base plate 10 or the second base plate 20 by screws or other connecting parts. The first base plate 10 or the second base plate 20 is provided with through holes 5104 corresponding to the positioning hole 5102, and the extension direction of the slots 5103 on the outer surface of the base 510 is consistent with the axial direction of the mounting cavity 5101, and they are spaced apart on the outer surface of the base 510. The front end of the handle 520 is provided with a U-shaped groove. After the rotary lock head 530 is installed in the mounting cavity 5101, the U-shaped groove wall of the handle 520 is fixedly connected to the two ends of the rotary lock head 530 by screws, so that the handle 520 can drive the rotary lock head 530 relative to the base. The handle 520 is rotated. The locking lock 540 is installed on the handle 520. One end has a locking head 5401 that engages with the slot 5103, and the other end is a button 5402 that extends out of the handle 520. When the rotating lock head 530 needs to be rotated, the handle 520 is held while the button 5402 is pressed, causing the button 5402 to move the locking head 5401 away from the slot 5103, thus unlocking the handle 520 from the base 510. When the locking head 5401 re-engages with the slot 5103, the handle 520 is locked, and the locking lock 540 needs to be pressed again to unlock it. The locking fastener 50 has a simple structure and is practical and convenient. During operation, the locking and unlocking of the handle 520 can be completed through the cooperation between the locking lock 540, the base 510, and the handle 520. The overall components are few, and each part is installed with a small number of screws, making maintenance more convenient and quick.

[0057] Furthermore, in other preferred embodiments of this utility model, a plurality of the slots 5103 are spaced apart on the outer surface of the base 510; and the latch 5301 extends along the outer wall of the rotary lock head 530. The latch 5301 has a large end 53011 and a small end 53012. When the latch head 5401 engages with the slots 5103 respectively, the small end of the latch 5301 is aligned with the positioning hole 5102 to keep the handle 520 in the locked position, or the large end of the latch 5301 is aligned with the positioning hole 5102 to keep the handle 520 in the unlocked position.

[0058] Specifically, in one feasible implementation, the slots 5103 are at least one spaced apart, and the latches 5301 extend along the outer wall of the rotary lock head 530. The latches 5301 have a large end 53011 and a small end 53012. The large end 53011 and the small end 53012 cooperate with the mushroom-shaped locking post on the display frame 1. The large end 53011 allows the mushroom-shaped locking post to pass freely, while the small end 53012 prevents the mushroom-shaped locking post from passing through, thus forming a lock. When the locking head 401 of the locking lock 540 engages with the slots 5103, the small end 5301 of the latches 5301... 2. Align the handle 520 with the positioning hole 5102 to keep the handle 520 in the locked position, or align the large end 53011 of the latch 5301 with the positioning hole 5102 to keep the handle 520 in the unlocked position. On the other hand, the slot 103 used to keep the handle 520 in the unlocked position can also be omitted. In another feasible embodiment, at least three slots 5103 can be set, so as to realize at least three states: locked state, unlocked state, and intermediate state. For example, the locking state can be divided into multiple levels by adjusting the depth of each slot 5103 according to the required degree of locking. The multiple levels of slots 5103 can be set continuously. Thus, this utility model can be configured with multiple positions. Based on the overall utility model concept, this utility model can be configured with multiple positions. For example, each time it is rotated by a certain preset angle, the locking component 50 of this utility model will be in a certain position state. This can be used to achieve a more complex state or to extend or modify the technology to improve the locking force. All of these are within the protection scope of this utility model.

[0059] Furthermore, in other preferred embodiments of this utility model, the locking lock 540 and the handle 520 are connected by a rotating shaft 5403, and a return spring 5404 is provided on the rotating shaft 5403.

[0060] Specifically, the pivot 5403 is positioned between the button 5402 and the latch 5401, thus forming a lever between the button 5402 and the latch 5401. When the button 5402 is pressed, the latch 5401 will be lifted, thereby releasing the lock between the handle 520 and the base 510. The reset spring 5404 can assist in the reset of the button 5402, making operation more convenient and also facilitating the locking of the latch 5401.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, and not to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
