[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0036] 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.

[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 transmission link 10, a drive block 20, and a locking pin 30.

[0039] Please combine Figure 2-3 The transmission link 10 is provided with a rotating shaft 110 and can rotate around the rotating shaft 110. The first end 101 and the second end 102 of the transmission link 10 are located on both sides of the rotating shaft 110. The drive block 20 is rotatably connected to the first end 101. The locking pin 30 is rotatably connected to the second end 102. When the drive block 20 slides along the first direction, it can drive the locking pin 30 to slide along the second direction opposite to the first direction through the transmission link 10.

[0040] Specifically, the drive block 20 and the locking pin 30 are located on both sides of the transmission link 10, and are rotatably connected to the first end 101 and the second end 102 respectively through a hinge shaft. The rotating shaft 110 is located near the middle of the transmission link 10. The transmission link 10 can rotate around the rotating shaft 110, so that the drive block 20 and the locking pin 30 form a seesaw. When the drive block 20 slides in the first direction, it can drive the locking pin 30 to slide in the second direction opposite to the first direction through the transmission link 10. For example, when the drive block 20 slides downward (as shown by the dotted arrow in the figure), the locking pin 30 is lifted by the drive block 20 through the transmission link 10, so that the locking pin 30 slides upward (as shown by the dotted arrow in the figure), thereby locking and connecting the head end of the locking pin 30 with the lock body of another display screen lock.

[0041] When the display lock of this utility model is applied to the display frame, the locking pin 30 can be hidden inside the frame or extend outside the frame. When it extends outside the frame, it can be used to connect with the display lock of the adjacent screen, while when it is hidden inside the frame, it will not affect the placement of the screen and thus improve the security of the screen placement.

[0042] Furthermore, in other preferred embodiments of the present invention, the display screen lock further includes a housing 40, the transmission link 10, the drive block 20 and the locking pin 30 are all disposed in the housing 40, the side of the housing 40 is provided with a pivot hole 410 for the pivot 110 to pass through, and the housing 40 is provided with a first through hole 401 opposite to the end of the drive block 20 and a second through hole 402 opposite to the end of the locking pin 30.

[0043] Specifically, the housing 40 is used to enclose the transmission link 10, the drive block 20, and the locking pin 30. A pivot hole 410 is provided in the middle of the side of the housing 40, and the pivot 110 passes through the pivot hole 410 to connect the transmission link 10 to the housing 40. A first through hole 401 and a second through hole 402 are respectively provided on the side of the housing 40. The first through hole 401 is opposite to the end of the drive block 20 so as to apply a pushing force to the drive block 20 through the first through hole 401, while the second through hole 402 is opposite to the end of the locking pin 30 so that the end of the locking pin 30 can extend out of the housing 40.

[0044] Furthermore, in other preferred embodiments of the present invention, the housing 40 includes an outer shell 420 and a cover plate 430, and the first through hole 401 and the second through hole 402 are both disposed on the side of the outer shell 420 opposite to the cover plate 430;

[0045] The outer casing 420 is provided with a positioning post 440 on the side facing the cover plate 430, and the cover plate 430 is provided with a positioning hole 450 for the positioning post 440 to pass through.

[0046] Specifically, the outer casing 420 is a groove-shaped structure with its opening facing the cover plate 430. The transmission connecting rod 10, the drive block 20, and the locking pin 30 are disposed within the groove. The cover plate 430 is connected to the groove of the outer casing 420 by fasteners such as screws. The first through hole 401 and the second through hole 402 are disposed on the side of the outer casing 420 facing away from the cover plate 430. To facilitate the connection between the outer casing 420 and the cover plate 430, a positioning pin 440 is provided protruding from the side of the outer casing 420 facing the cover plate 430, and a positioning hole 450 is provided on the cover plate 430 for the positioning pin 440 to pass through.

[0047] In addition, in other preferred embodiments of the present invention, a spring 50 is also included. The spring 50 is disposed inside the outer casing 420, with one end abutting against the cover plate 430 and the other end abutting against the end of the drive block 20 away from the first through hole 401.

[0048] Specifically, the spring 50 is also disposed within the housing 420, positioned between the drive block 20 and the cover plate 430, with one end abutting against the cover plate 430 and the other end abutting against the end of the drive block 20 away from the first through hole 401. With this design, when a force greater than the elastic force of the spring 50 is applied to the drive block 20, the spring 50 is compressed, causing the drive block 20 to slide closer to the cover plate 430; when the force applied to the drive block 20 is removed, the drive block 20, under the elastic force of the spring 50, slides away from the cover plate 430 to return to its initial position.

[0049] Furthermore, in other preferred embodiments of the present invention, the locking pin 30 includes a locking body 310 and a driven block 320 connected together. The driven block 320 is disposed on the side of the locking body 310 facing away from the second through hole 402 and is rotatably connected to the second end 102. When the locking pin 30 slides along the second direction, the end of the locking body 310 away from the driven block 320 can extend out of the second through hole 402.

[0050] The locking pin 30 includes a locking body 310 and a driven block 320 connected together. One end of the driven block 320 is connected to the locking body 310, and the other end of the driven block 320 is rotatably connected to the second end 102 of the transmission link 10 through a hinge shaft. One end of the locking body 310 is a free end that can extend or retract into the second through hole 402, and the other end of the locking body 310 is a connecting end that is fixedly connected to the driven block 320. When the locking pin 30 slides along the second direction (as shown by the dotted arrow in the figure), the end of the locking body 310 away from the driven block 320 can extend out of the second through hole 402.

[0051] Furthermore, in other preferred embodiments of this invention, the end of the lock body 310 away from the driven block 320 is provided with a mushroom head (not shown in the figure); or,

[0052] The end of the lock body 310 away from the driven block 320 is provided with a locking pin 330 that is perpendicularly connected to the lock body 310.

[0053] Specifically, in one feasible embodiment of this utility model, the end of the lock body 310 away from the driven block 320 is provided with a mushroom head, the size of which is larger than the outer diameter of the lock body 310 at its lower end, and the matching display screen lock can be a gourd lock hole structure with the large and small lock holes connected together; in another feasible embodiment of this utility model, the end of the lock body 310 away from the driven block 320 is connected to the locking pin 330, the locking pin 330 and the lock body 310 form a cross shape at their ends, and the matching display screen lock can be a hook structure that can hook the locking pin 330 together.

[0054] In other preferred embodiments of this utility model, the driving block 20 and the locking pin 30 are provided with ball bearings (not shown in the figure) on their respective sides, and the inner wall of the housing 40 is provided with a groove (not shown in the figure) that can accommodate the ball bearings.

[0055] Here, since both the drive block 20 and the locking pin 30 need to reciprocate within the housing 40, in order to prevent misalignment during the sliding process and to facilitate precise alignment with the first through hole 401 and the second through hole 402, the drive block 20 and the locking pin 30 are provided with ball bearings on their respective sides that are far apart from each other. At the same time, the inner wall of the housing 40 is provided with a sliding groove, and the ball bearings extend into the sliding groove to provide a sliding track for the reciprocating sliding of the drive block 20 and the locking pin 30.

[0056] Additionally, please refer to Figure 4This is a partial three-dimensional structural diagram of a display screen frame provided by an embodiment of the present utility model. The display screen frame includes a first support rod 1 and any of the display screen locks 2 described in the above embodiments. The display screen lock 2 is disposed inside the first support rod 1. When the driving block 20 slides along a first direction close to the center of the frame, it can drive the locking pin 30 to slide along a second direction away from the center of the frame through the transmission link 10, so that the head end of the locking pin 30 extends out of the first support rod 1.

[0057] Specifically, the housing 40 of the display lock 2 is fixedly connected to the first frame rod 1 by screws or other connecting parts. When the drive block 20 slides along the first direction close to the center of the frame, the transmission link 10 can drive the locking pin 30 to slide along the second direction away from the center of the frame, so that the head end of the locking pin 30 extends out of the first frame rod 1. At this time, the locking pin 30 can be connected to the display lock on another display frame to complete the connection of the two display frames.

[0058] Furthermore, in other preferred embodiments of the present invention, the display screen frame further includes a second support rod 3 opposite to the first support rod 1, and the second support rod 3 is provided with a top column 31 that can push the drive block 20 to slide along the first direction;

[0059] The second support rod 3 is also provided with a connecting lock 4, which is a locking mechanism that forms a lock with the head end of the locking pin 30 when the head end of the locking pin 30 extends out of the first support rod 1.

[0060] Specifically, the first support rod 1 and the second support rod 3 are two opposing support rods on the display screen frame. To clearly illustrate the structure that solves the technical problem in this embodiment, the accompanying drawings of this embodiment only show a partial view of the display screen frame. When two display screen frames are spliced ​​together, the first support rod 1 of one display screen frame is opposite to the second support rod 3 of the other display screen frame and connected together by a display screen lock. The top post 31 is provided protruding from the second support rod 3. When the two display screen frames are spliced ​​together, the top post 31 can extend into the first through hole 401 of the display screen lock 2 to apply a pushing force to the driving block 20, thereby causing the head end of the locking post 30 to extend out of the first support rod 1. When the head end of the locking post 30 extends out of the first support rod 1, it can lock with the connecting lock 4 on the second support rod 3 to complete the connection of the two display screen frames.

[0061] Furthermore, to make the connection between the two display screen frames more reliable, two display screen locks 2 are respectively installed near both ends of the first support rod 1. That is, a display screen lock 2 is provided at each end of the first support rod 1, and correspondingly, two connecting locks 4 are also provided at corresponding positions on the second support rod 3. The two connecting locks 4 and the two display screen locks 2 are connected together to ensure the reliability of the connection between the two display screen frames on this side.

[0062] Please combine Figure 5 This is an exploded three-dimensional structural diagram of a display screen frame provided in an embodiment of the present utility model. The connecting lock 4 includes a handle 41, a locking rod 42, and two locking grooves 43.

[0063] The two locking grooves 43 are respectively fixedly connected to the two ends of the locking rod 42 and are set in the second frame rod 3;

[0064] The handle 41 passes through the second frame rod 3 and is fixedly connected to the middle position of the locking rod 42, and can drive the locking rod 42 to switch between the locked position and the unlocked position.

[0065] When the locking rod 42 is rotated to the locked position, the locking groove 43 can be locked and connected with the locking pin 30; when the locking rod 42 is rotated to the unlocked position, the locking pin 30 can be disengaged from the locking groove 43.

[0066] Specifically, the handle 41 has a U-shaped structure, with its two ends passing through the second support rod 3 and fixedly connected to the locking rod 42. The ends of the locking rod 42 that are far apart from each other are respectively provided with a locking groove 43. By rotating the handle 41, the locking rod 42 can be rotated, thereby causing the two locking grooves 43 to rotate as well. When the locking rod 42 rotates to the first position, the locking groove 43 can be locked and connected with the locking pin 30, that is, this is the locked position. When the locking rod 42 rotates to the second position, the locking pin 30 can be disengaged from the locking groove 43, that is, this is the unlocked position. In other words, the handle can drive the locking rod 42 to switch between the locked position and the unlocked position.

[0067] In one feasible embodiment of this utility model, when the head end of the locking pin 30 is a mushroom head, the locking groove 43 is provided with a large lock hole and a small lock hole that are interconnected. The large lock hole can allow the mushroom head to pass through, while the diameter of the small lock hole is smaller than the diameter of the mushroom head.

[0068] In another feasible embodiment of this utility model, when the end of the lock body 310 away from the driven block 320 is provided with a locking pin 330 that is perpendicularly connected to the lock body 310, the lock groove includes a first groove, a second groove, and a lock hook. The first groove is provided on the lock hook for the lock body 310 to be inserted, and the second groove is located in the opening direction of the lock hook for the head end of the column and the locking pin to be inserted.

[0069] Furthermore, the connecting lock 4 also includes a limiting block 44 fixedly connected to the second frame rod 3;

[0070] One end of the handle 41 is opposite to the limiting block 44, and a plurality of limiting grooves 441 are provided on the side of the limiting block 44 facing the end;

[0071] A limiting rod 45 is also provided on the handle 41. One end of the limiting rod 45 is provided with a limiting post 451 that can be inserted into the limiting groove 441, and the other end of the limiting rod 45 is provided with a button 452 that drives the limiting post 451 to move.

[0072] Specifically, the limiting block 44 is fixedly connected to the second support rod 3 and is opposite to one end of the handle 41. The limiting block 44 is provided with the plurality of limiting grooves 441 on the side of the end facing the handle 41. The U-shaped handle 41 is provided with a limiting rod 45 on the side opposite to the limiting block 44. The middle part of the limiting rod 45 is rotatably connected to the handle 41 through a connecting shaft. The two ends of the limiting rod 45 are the button 452 and the limiting post 451, respectively. When the button 452 is operated, the limiting post 451 can be inserted into the limiting groove 441, thereby restricting the handle 41 from rotating relative to the second support rod 3. When the button 452 is operated, the limiting post 451 is disengaged from the limiting groove 441, thereby releasing the restriction of the limiting post 451 on the rotation of the handle 41 relative to the second support rod 3, allowing the handle 41 to resume rotation.

[0073] Furthermore, a torsion spring 46 is sleeved on the connecting shaft that rotatably connects the limiting rod 45 and the handle 41. The two ends of the torsion spring 46 are respectively connected to the limiting rod 45 and the handle 41. When the force of pressing the button 452 is greater than the elastic force of the torsion spring 46, one end of the limiting post 451 will tilt up, causing the limiting post 451 to disengage from the limiting groove 441, thereby releasing the limitation of the limiting post 451 on the rotation of the handle 41 relative to the second support rod 3. When the handle 41 is rotated to the preset position, the force of pressing the button 452 is removed, and one end of the limiting post 451 will re-insert into the limiting groove 441 under the action of the elastic force of the torsion spring 46, thereby restricting the rotation of the handle 41 relative to the second support rod 3.

[0074] 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.
