[0019] 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.

[0020] Please refer to Figure 1 This is an exploded three-dimensional structural diagram of a display screen lock provided by an embodiment of the present utility model. The display screen lock includes a first locking member 10 and a second locking member 20. The first locking member 10 and the second locking member 20 are fixedly connected to two adjacent display screen frames. For example, the first locking member 10 is fixedly connected to the left side of the display screen frame of an LED display screen by screws, while the second locking member 20 is fixedly connected to the right side of the display screen frame of an LED display screen adjacent to the aforementioned LED display screen by screws.

[0021] Please combine Figure 2-4 The first locking member 10 includes a handle 110 and a hook 120. The hook 120 includes a connecting end 1201 and a locking hook 1202 away from the connecting end 1201. The handle 110 includes a first end 1101 and a second end 1102 opposite to each other. The first end 1101 is connected to the connecting end 1201. The second locking member 20 includes a lock seat 210. The lock seat 210 has a lock groove 2101 with an opening facing away from the first locking member 10. Rotating the second end 1102 by a threshold angle in a first direction away from the second locking member 20 can cause the locking hook 1202 to extend onto the lock seat 210. Continuing to rotate the second end 1102 by the threshold angle in a second direction opposite to the first direction can cause the locking hook 1202 to sink into the lock groove 2101.

[0022] Specifically, the handle 110 and hook 120 of the first locking member 10 are disposed on the side of the display frame. The handle 110 is generally elongated and includes a first end 1101 and a second end 1102 opposite to each other. The first end 1101 can be regarded as a fixed end, while the second end 1102 is a free end that can rotate around the first end 1101. The hook 120 is generally arc-shaped. One end is the connecting end 1201 connected to the first end 1101. This connection can be direct or indirect. The end away from the connecting end 1201 is the locking hook 1202, which is used to connect with the second locking member 20. The locking seat 210 is disposed on the side of the adjacent display frame opposite to the first end 1101. It has a locking groove 2101 with an opening facing away from the first locking member 10. That is, the opening direction of the locking groove 2101 is towards the center of the display frame where it is located.

[0023] When in use, i.e., when the left and right LED displays need to be connected together, by rotating the second end 1102 by a threshold angle in the first direction away from the second locking member 20, the threshold angle can be set according to the specifications of the display lock, which is generally 90 degrees. This can drive the locking hook 1202 to extend above the locking base 210. Then, continue to rotate the second end 1102 in the second direction, which is opposite to the first direction. This can be understood as rotating the second end 1102 back. The angle of rotation is also the threshold angle, which can be understood as the second end 1102 returning to its position before the first rotation. However, after the rotation, it can drive the locking hook 1202 into the locking groove 2101 to connect the first locking member 10 and the second locking member 20 together, thereby completing the locking connection between the left and right LED displays.

[0024] In this embodiment, when locking, rotating the second end 1102 by a threshold angle in a first direction away from the second locking member 20 allows the locking hook 1202 to extend onto the locking seat 210. Continuing to rotate the second end by the threshold angle in a second direction opposite to the first direction allows the locking hook 1202 to sink into the locking groove 2101, thus completing the locking process. The entire process can be completed simply by rotating the handle 110, making the structure simple and easy to operate. Furthermore, the handle can fit snugly against the display frame in both locked and unlocked states, which is more conducive to the transportation and use of the display screen.

[0025] Furthermore, in other preferred embodiments of the present invention, the display screen lock further includes a transmission component 30, wherein the first end 1101 is connected to one end of the transmission component 30 via a first rotating shaft 301, and the other end of the transmission component 30 is connected to the connecting end 1201.

[0026] Here, the handle 110 and the hook 120 are indirectly connected, that is, the transmission member 30 is added between them; specifically, the first rotating shaft 301 is provided on the first end 1101. When the second end 1102 rotates relative to the first end 1101, the first rotating shaft 301 can rotate accordingly, thereby driving the transmission member 30 to rotate as well. The other end of the transmission member 30 is connected to the connecting end 1201 of the hook 120, so that the rotation of the transmission member 30 can drive the hook 120 to rotate, so that the lock hook 1202 can extend onto the lock seat 210 and sink into the lock groove 2101 to complete the locking.

[0027] Furthermore, in other preferred embodiments of this utility model, the display lock further includes a tension spring 40; The transmission component 30 is provided with a second rotating shaft 302 at one end away from the connecting end 1201, and the connecting end 1201 is also provided with a third rotating shaft 303; The two ends of the tension spring 40 are respectively connected to the second rotating shaft 302 and the third rotating shaft 303. When the locking hook 1202 is inserted into the locking groove 2101, the tension spring 40 is stretched.

[0028] Specifically, the transmission component 30 has a groove-shaped structure, and the tension spring 40 is disposed in the receiving groove of the transmission component 30. A second rotating shaft 302 is provided at one end of the receiving groove away from the connecting end 1201, and one end of the tension spring 40 is connected to it. A third rotating shaft 303 is provided on the connecting end 1201 of the hook 120, and the other end of the tension spring 40 is connected to it. When the locking hook 1202 is inserted into the locking groove 2101, the tension spring 40 is in a stretched state, thereby fixing the locking hook 1202 tightly in the locking groove 2101, effectively improving the locking connection firmness between the two LED displays and preventing relative shaking between the two LED displays.

[0029] In addition, in other preferred embodiments of the present invention, a fourth rotating shaft 304 is provided on the transmission member 30 on the side of the second rotating shaft 302 and the third rotating shaft 303 facing the first rotating shaft 301.

[0030] Specifically, the fourth pivot 304 is located between the second pivot 302 and the third pivot 303, but on the side facing the first pivot 301, that is, on the side close to the locking hook 1202. In this way, when the handle 110 is not rotated, that is, when locking is not performed, the hook 120 is restricted, preventing it from rotating towards the second locking member 20 and extending out of the display frame body, which is beneficial for the packaging and transportation of the LED display.

[0031] Furthermore, in other preferred embodiments of this utility model, the display lock further includes a mounting base 50, which is fixedly connected to the display frame opposite to the second locking member 20. The mounting base 50 has a mounting groove 501, the connecting end 1201 is disposed in the mounting groove 501, and the locking hook 1202 can be hidden in the mounting groove 501 or extend out of the mounting groove 501; The handle 110 is located on the side of the mounting base 50 away from the display screen frame, and the first end 1101 passes through the mounting base 50 and is connected to the connecting end 1201.

[0032] In the above embodiments, the first locking member 10 and the transmission member 30 can be considered as being directly mounted on the display screen frame. In this embodiment, the mounting base 50 can be considered as the mounting base for the first locking member 10 and the transmission member 30. Specifically, the mounting base 50 is fixedly connected to the display screen frame opposite to the second locking member 20 by screws or the like. A mounting groove 501 is provided on the side facing the second locking member 20. The connecting end 1201 of the hook 120 is disposed within the mounting groove 501. The locking hook 1202 can be hidden by rotating the hook 120. The handle 110 is located within or extends beyond the mounting slot 501. Being hidden within the mounting slot 501 can be considered the unused state (unlocked state) of the display screen lock, while being extended beyond the mounting slot 501 can be considered the used state (locked state). The handle 110 is located on the side of the mounting base 50 facing away from the display screen frame. By setting the first rotating shaft 301 at the first end 1101, the first rotating shaft 301 can pass through the mounting base 50 and connect to the connecting end 1201, thereby completing the transmission connection between the handle 110 and the hook 120.

[0033] Furthermore, in other preferred embodiments of the present invention, the mounting base 50 is provided with a first positioning hole 510 on the side facing the second locking member 20, and a first positioning pin 2102 is provided in the locking groove 2101, the first positioning pin 2102 being able to slide within the locking groove 2101; When the locking hook 1202 is inserted into the locking groove 2101, the front end of the first positioning pin 2102 will be squeezed out of the locking groove 2101 by the locking hook 1202 and inserted into the first positioning hole 510.

[0034] Specifically, the first positioning hole 510 is provided on the side of the mounting base 50, that is, the side facing the second locking member 20; the first positioning pin 2102 is provided in the lock groove 2101, which can slide back and forth in the direction close to the first locking member 10 and away from the first locking member 10. When the lock hook 1202 is inserted into the lock groove 2101, the front end of the first positioning pin 2102 will be squeezed out of the lock groove 2101 by the lock hook 1202 and inserted into the first positioning hole 510, so as to achieve precise positioning between the first locking member 10 and the second locking member 20, and prevent misalignment between the two from affecting locking.

[0035] In addition, in other preferred embodiments of the present invention, the locking groove 2101 is provided with a through hole 2103 opposite to the first positioning hole 510, a spring 2104 is sleeved on one end of the first positioning pin 2102 near the mounting base 50, and a boss 2105 is provided on one end of the first positioning pin 2102 away from the mounting base 50. The two ends of the spring 2104 abut against the boss 2105 and the hole wall of the through hole 2103, respectively; The boss 2105 is provided with a guide post 2106, and the wall of the through hole 2103 is provided with an elongated hole 2107 for the guide post 2106 to pass through and slide back and forth.

[0036] Specifically, a through hole 2103 penetrating the lock seat 210 is provided at the bottom of the lock groove 2101. The first positioning pin 2102 is disposed in the through hole 2103, one end of which abuts against the lock hook 1202 in the lock groove 2101, and the other end extends out of the lock seat 210 and is inserted into the first positioning hole 510. The diameter of the first positioning pin 2102 is not uniform; it is thinner at the end near the first lock member 10 and thicker at the end away from the first lock member 10, thus forming the boss 2105 at the junction of the two. The spring 2104 is sleeved on the end near the mounting base 50, that is, on the thinner end of the first positioning pin 2102, so that the two ends of the spring 2104 abut against the boss 2105 and the hole wall of the through hole 2103, respectively. In addition, in the The boss 2105 is vertically provided with the guide post 2106, and the wall of the through hole 2103 is provided with the elongated hole 2107 for the guide post 2106 to pass through and slide back and forth. The elongated hole 2107 provides a sliding track for the reciprocating sliding of the guide post 2106. When the locking hook 1202 is inserted into the locking groove 2101, the first positioning pin 2102 extends its front end out of the through hole 2103 under the pressure of the locking hook 1202 and inserts into the first positioning hole 510. When the locking hook 1202 is dislodged from the locking groove 2101, the first positioning pin 2102 retracts back into the through hole 2103 under the elastic force of the spring 2104, that is, it is dislodged from the first positioning hole 510, so that the first locking member 10 and the second locking member 20 can be separated.

[0037] Furthermore, in other preferred embodiments of the present invention, a second positioning hole (not shown in the figure) is provided on the side of the mounting base 50 facing the handle 110, and a second positioning pin 1103 is provided at the second end 1102 that can extend into the second positioning hole.

[0038] Specifically, the second positioning pin 1103 and the second positioning hole are respectively provided on the surfaces of the handle 110 and the mounting base 50 that are in contact with each other. The second positioning pin 1103 can be inserted into the second positioning hole, thereby connecting the handle 110 and the mounting base 50 together and fixing the handle 110, thus preventing the handle 110 from being accidentally rotated.

[0039] In addition, in other preferred embodiments of the present invention, the second lock member 20 further includes a first guide member 220. The first guide member 220 is disposed on the lock seat 210 and has an arc-shaped guide surface 2201 facing away from the opening direction of the lock groove 2101. The arc-shaped guide surface 2201 is used to guide the movement trajectory of the lock hook 1202 as it enters the lock groove 2101 on the lock seat 210.

[0040] Specifically, the first guide member 220 is disposed on the lock seat 210, and its tail end is located at the opening of the lock groove 2101. The arc-shaped guide surface 2201 is located on the side of the first guide member 220 facing away from the opening of the lock groove 2101. When the hook 120 rotates, the lock hook 1202 can move along the arc-shaped guide surface 2201, so that it can slide accurately and quickly into the lock groove 2101 to complete the locking. This means that the arc-shaped guide surface 2201 of the first guide member 220 plays a role in accurately and quickly guiding the movement trajectory of the lock hook 1202 sliding into the lock groove 2101 on the lock seat 210.

[0041] Furthermore, in other preferred embodiments of the present invention, the second lock member 20 further includes a second guide member 230, the second guide member 230 including a guide head 2301 and a torsion spring 2302. The guide head 2301 is disposed at one end of the first guide member 220 opposite to the opening direction of the lock groove 2101. The guide head 2301 includes a mounting shaft 2303 that can be inserted into the lock seat 210 and a guide portion 2304 that forms a threshold angle with each other. The torsion spring 2302 is sleeved on the mounting shaft 2303, and the two support arms of the torsion spring 2302 are respectively inserted into the lock seat 210 and one of the guide portions 2304.

[0042] Specifically, a groove is provided on the lock seat 210 at the tail end of the first guide member 220, and the guide head 2301 is disposed in the groove. The torsion spring 2302 is sleeved on the mounting shaft 2303 and placed in the groove. The two support arms of the torsion spring 2302 are respectively inserted into the groove wall and one of the guide parts 2304, thereby enabling the guide head 2301 to rotate to a certain extent within the groove. When locking, the second end 1102 is rotated in the first direction to extend the hook 120. The locking hook 1202 slides along the arc-shaped guide surface 2201 of the first guide member 220 on the lock seat 210. After sliding out of the arc-shaped guide surface 2201, it contacts the first guide portion 2304 of the guide head 2301, pushing the guide head 2301 to rotate. After the locking hook 1202 moves between the two guide portions 2304, the second end 1102 is rotated in the second direction. The locking hook 1202 slides towards the lock groove 2101, contacts the second guide portion 2304 of the guide head 2301, and pushes the guide head 2301. When rotated, the locking hook 1202 passes the second guide portion 2304 of the guide head 2301 and enters the locking groove 2101 to complete locking. When unlocking is required, the second end 1102 is rotated in the first direction to make the locking hook 1202 slide out of the locking groove 2101. After sliding out of the locking groove 2101, it will abut against the second guide portion 2304 of the guide head 2301. At this time, rotating the second end 1102 in the second direction will cause the locking hook 1202 to slide out of the lock seat 210 along the arc-shaped guide surface 2201 and return to its original position, so that the first locking member 10 and the second locking member 20 can be separated to complete unlocking.

[0043] 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.
