Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to a display screen lock. Background Technology

[0002] In venues such as stages and exhibitions, large display screens are generally required. However, excessively large screens are inconvenient to transport. The current solution is to use splicing locks to combine multiple screens into one large screen, thereby increasing the display size. However, current splicing locks typically lock adjacent screens by rotating the handle in one direction to a certain angle. To unlock, the handle is usually rotated in the opposite direction, which is inconvenient. Furthermore, in one of the locked or unlocked states, the handle protrudes outside the screen frame, adding to the overall size of the screen and hindering its transportation and use. Utility Model Content

[0003] In view of the above problems, embodiments of the present invention are proposed to provide a display lock that solves or at least partially solves the above problems.

[0004] This utility model embodiment provides a display screen lock, which includes a first locking member and a second locking member disposed opposite to each other on two adjacent display screen frames; The first locking component includes a handle, a disc, and a latch. The handle includes a first end and a second end, which are opposite to each other. The first end is connected to the disc. The latch is sleeved on the outer periphery of the disc, and the outer wall of the latch is provided with a latch portion. The second locking component includes a lock base, which has a lock groove with an opening facing away from the first locking component; Specifically, rotating the second end by a first threshold angle in a first direction away from the second locking member can cause the buckle to rotate via the disc, so that the buckle extends onto the lock seat; continuing to rotate the second end by a second threshold angle in the first direction can cause the disc to move the buckle away from the second locking member so that the buckle sinks into and tightens the lock groove.

[0005] Furthermore, the sum of the first threshold angle and the second threshold angle is 180 degrees.

[0006] Furthermore, the first locking member also includes a first pushing member and a first limiting member; The middle part of the first pusher is rotatably connected to the fastener and has a third end and a fourth end opposite to each other; The disc has a receiving hole, and the first limiting member is disposed in the receiving hole. The end of the first limiting member can extend out of the receiving hole and insert into the notch of the fastener and abut against the third end, or the end of the first limiting member can retract into the receiving hole under the push of the third end.

[0007] Furthermore, a first spring is provided inside the receiving hole, one end of the first spring abuts against the bottom of the receiving hole, and the other end of the first spring is sleeved on the end of the first limiting member that is away from the third end.

[0008] Furthermore, when the buckle extends to the lock seat, the fourth end will abut against the lock seat, and the second end will continue to rotate to make the first pusher rotate, thereby causing the third end to push the first limiting member to retract into the receiving hole.

[0009] Furthermore, the rotation of the disc is a non-centered rotation. After the first limiting member retracts into the receiving hole, the second end continues to rotate, and the disc can drive the buckle to move away from the second locking member.

[0010] Furthermore, the first locking member also includes a mounting base, a second pushing member, and a second limiting member. The mounting base has a mounting groove with an opening facing the second locking member. The disc, the latch, the second pushing member, and the second limiting member are all disposed in the mounting groove. The middle part of the second pusher is rotatably connected to the groove wall of the mounting groove. One end of the second pusher abuts against the outer wall of the buckle and the other end of the second pusher abuts against the second limiting member. When the disc drives the buckle to move away from the first locking member, the second pusher can push the second limiting member to move so that its end extends out of the mounting base. The lock seat has a first positioning hole on the side facing the mounting base, which can accommodate the end of the second limiting member.

[0011] Furthermore, a second spring is sleeved on the end of the second limiting member near the second pushing member. After the second pushing member releases its pushing force on the second limiting member, the second spring can drive the second limiting member to retract into the mounting base.

[0012] Furthermore, the first locking component also includes a third spring, which is disposed between the outer wall of the disc and the inner wall of the fastener, with its two ends connected to the disc and the fastener respectively. After the end of the second limiting member is inserted into the first positioning hole, the second end is rotated in the second direction opposite to the first direction. The disc drives the fastener to move closer to the second locking member. The fastener moves in the groove towards the opening. The end of the second limiting member disengages from the first positioning hole. Under the action of the third spring, the fastener rotates relative to the disc until the end of the first limiting member extends out of the receiving hole and inserts into the notch of the fastener. The second end is then rotated in the second direction. The disc drives the fastener to rotate, causing the fastener to retract into the mounting groove.

[0013] Furthermore, the mounting base is disposed within the support rod of the display screen frame, the handle is disposed on the surface of the support rod, the side of the support rod facing the handle is provided with a second positioning hole, and the second end is provided with a positioning pin that can extend into the second positioning hole.

[0014] In the technical solution provided by this utility model embodiment, the display screen lock includes a first locking member and a second locking member disposed opposite to each other on two adjacent display screen frames. The first locking member includes a handle, a disc, and a fastener. The handle includes a first end and a second end opposite to each other. The first end is connected to the disc, and the fastener is sleeved on the outer periphery of the disc. The outer wall of the fastener has a fastening portion. The second locking member includes a lock seat with a lock groove opening facing away from the first locking member. Rotating the second end by a first threshold angle in a first direction away from the second locking member can cause the fastener to rotate through the disc, so that the fastening portion extends onto the lock seat. Continuing to rotate the second end by a second threshold angle in the first direction can cause the disc to move the fastener away from the first locking member, so that the fastening portion sinks into and tightens the lock groove, thus completing the locking. Locking can be completed simply by moving the handle in one direction, making the structure simple and the operation convenient. Moreover, the handle can fit against the display screen frame in both the locked and unlocked states, which is more conducive to the transportation and use of the display screen.

[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 2-5 The first locking member 10 includes a handle 110, a disc 120, and a fastener 130. The handle 110 includes a first end 1101 and a second end 1102, which are opposite to each other. The first end 1101 is connected to the disc 120. The fastener 130 is sleeved on the outer periphery of the disc 120, and the outer wall of the fastener 130 is provided with a fastening portion 1301. The second lock member 20 includes a lock base 210, which has a lock groove 2101 with an opening facing away from the first lock member 10; Specifically, rotating the second end 1102 by a first threshold angle in a first direction away from the second locking member 20 can cause the buckle 130 to rotate via the disc 120, so that the buckle portion 1301 extends onto the lock seat 210; continuing to rotate the second end 1102 by a second threshold angle in the first direction can cause the disc 120 to move the buckle 130 away from the second locking member 20 so that the buckle portion 1301 sinks into and tightens the lock groove 2101.

[0022] Specifically, the handle 110 is fixedly connected to the disc 120 via a rotating shaft, and the fastener 130 is sleeved on the outer periphery of the disc 120. Rotating the handle 110 can drive the disc 120 to rotate, thereby driving the fastener 130 to rotate, so that the fastener portion 1301 located on the outer wall of the fastener 130 rotates to the lock seat 210 of the second lock 20, specifically extending into the lock groove 2101. Continuing to rotate the handle 110, the disc 120 can drive the fastener 130 to move away from the second lock 20, so that the fastener portion 1301 can be completely inserted into the bottom of the lock groove 2101 and tighten the lock groove 2101, thus completing the locking operation between the first lock 10 and the second lock. In this embodiment, both rotations of the handle 110 are in one direction (the first direction away from the direction of the second locking member 20), which can be regarded as a continuous rotation operation. That is, locking can be completed by simply moving the handle in one direction. The structure is simple and the operation is convenient. Moreover, the handle can fit on the display frame in both the locked and unlocked states, which is more conducive to the transportation and use of the display.

[0023] Furthermore, in other preferred embodiments of this utility model, the sum of the first threshold angle and the second threshold angle is 180 degrees, meaning that rotating the handle 110 180 degrees can lock or unlock the device. This design ensures that the handle 110 can fit snugly against the display frame in both the locked and unlocked states, which is beneficial for the transportation and use of the display screen.

[0024] Furthermore, in other preferred embodiments of the present invention, the first locking member 10 further includes a first pushing member 140 and a first limiting member 150; The middle part of the first pusher 140 is rotatably connected to the buckle 130, and has a third end 1401 and a fourth end 1402 opposite to each other; The disc 120 is provided with a receiving hole 1201, and the first limiting member 150 is disposed in the receiving hole 1201. The end of the first limiting member 150 can extend out of the receiving hole 1201 and insert into the notch of the fastener 130 and abut against the third end 1401, or the end of the first limiting member 150 can retract into the receiving hole 1201 under the push of the third end 1401.

[0025] Here, in the initial state where the first locking member 10 is not connected to the second locking member 20, the end of the first limiting member 150 is able to extend out of the receiving hole 1201 and be inserted into the notch of the fastener 130, so that the disc 120 and the fastener 130 can rotate together. That is, by rotating the handle 110, the disc 120 can be driven to rotate, which in turn drives the fastener 130 to rotate. At this time, the first pushing member 140 also rotates with the fastener 130. After the fastener 130 rotates a certain angle, the fourth end 1402 of the first pushing member 140 abuts against the lock seat 210, so that the end of the first limiting member 150 is pushed and squeezed back into the receiving hole 1201 by the third end 1401 of the first pushing member 140, so that the disc 120 and the fastener 130 can rotate relative to each other.

[0026] In addition, in other preferred embodiments of the present invention, a first spring 1202 is provided in the receiving hole 1201. One end of the first spring 1202 abuts against the bottom of the hole of the receiving hole 1201, and the other end of the first spring 1202 is sleeved on the end of the first limiting member 150 that is away from the third end 1401.

[0027] Specifically, in the initial state where the first locking member 10 is not connected to the second locking member 20, under the elastic force of the first spring 1202, the end of the first limiting member 150 away from the first spring 1202 will extend out of the receiving hole 1201 and be inserted into the notch of the fastener 130, thereby enabling the disc 120 and the fastener 130 to rotate together.

[0028] Furthermore, in other preferred embodiments of this utility model, when the buckle portion 1301 extends to the lock seat 210, the fourth end 1402 will abut against the lock seat 210, and the second end 1102 will continue to rotate to make the first pusher 140 rotate, thereby causing the third end 1401 to push the first limiting member 150 to retract into the receiving hole 1201.

[0029] Specifically, after the first pusher 140 rotates a certain angle with the fastener 130, the fourth end 1402 of the first pusher 140 abuts against the lock seat 210. If the second end 1102 continues to rotate at this time, the first pusher 140 will continue to rotate, thereby causing the third end 1401 to continue to push the first limiting member 150 and squeeze its end back into the receiving hole 1201. At this time, the rotation between the disc 120 and the fastener 130 stops, and instead the disc 120 and the fastener 130 rotate relative to each other.

[0030] Furthermore, in other preferred embodiments of this utility model, the rotation of the disc 120 is a non-centered rotation. After the first limiting member 150 retracts into the receiving hole 1201, the second end 1102 continues to rotate, and the disc 120 can drive the buckle 130 to move away from the second locking member 20.

[0031] Specifically, the rotating shaft connecting the handle 110 and the disc 120 is not located at the center of the disc 120. After the first limiting member 150 retracts into the receiving hole 1201 and releases the disc 120 and the buckle 130 from rotating together, the second end 1102 continues to rotate. Because the disc 120 rotates outside the center, it will move away from the second locking member 20, which will cause the buckle 130 to move away from the second locking member 20. This allows the buckle 1301 to be completely inserted into the bottom of the locking groove 2101 and tighten the locking groove 2101 to prevent the first locking member 10 and the second locking member 20 from shaking after they are connected.

[0032] Furthermore, in other preferred embodiments of the present invention, the first locking member 10 further includes a mounting base 160, a second pushing member 170, and a second limiting member 180. The mounting base 160 has a mounting groove 1601 with an opening facing the second locking member 20. The disc 120, the buckle 130, the second pushing member 170, and the second limiting member 180 are all disposed in the mounting groove 1601. The middle part of the second pusher 170 is rotatably connected to the groove wall of the mounting groove 1601. One end of the second pusher 170 abuts against the outer wall of the buckle 130, and the other end of the second pusher 170 abuts against the second limiting member 180. When the disc 120 drives the buckle 130 to move away from the first locking member 10, the second pusher 170 can push the second limiting member 180 to move so that its end extends out of the mounting base 160. The lock seat 210 is provided with a first positioning hole 2102 on the side facing the mounting base 160, which can accommodate the end of the second limiting member 180.

[0033] In the above embodiments, the components of the first locking member 10 can be considered as being directly mounted on the display screen frame. However, in this embodiment, the mounting base 160 can be considered as the mounting base for the other components of the first locking member 10. The mounting base 160 is fixedly connected to the display screen frame opposite to the second locking member 20, and has a mounting groove 1601 on its side facing the second locking member 20. The disc 120, the latch 130, the second pusher 170, and the second limiting member 180 are all located within the mounting groove 1601. As the first locking member 130 moves away from the second locking member, one end of the second pushing member 170 is pushed and squeezed by the outer wall of the latch member 130, which in turn pushes and squeezes the second limiting member 180 at the other end, so that the second limiting member 180 moves closer to the second locking member 20 and its end extends out of the mounting base 160 and is inserted into the first positioning hole 2102 of the lock base 210, thereby achieving precise positioning between the first locking member 10 and the second locking member 20 and preventing misalignment between them from affecting locking.

[0034] Furthermore, in other preferred embodiments of the present invention, a second spring 1801 is sleeved on the end of the second limiting member 180 near the end of the second pushing member 170. After the second pushing member 170 releases the pushing force on the second limiting member 180, the second spring 1801 can drive the second limiting member 180 to retract into the mounting base 160.

[0035] Specifically, the second spring 1801 is sleeved on the end of the second limiting member 180 near the second pushing member 170. When the first locking member 10 and the second locking member 20 are not locked, after the second pushing member 170 releases the pushing force on the second limiting member 180, the end of the second limiting member 180 away from the second pushing member 170 can retract into the mounting base 160 under the action of the second spring 1801, so that the display screen will not be restricted by the second limiting member 180 or damaged by the lamp board or lamp beads during the disassembly and assembly process.

[0036] Furthermore, in other preferred embodiments of the present invention, the first locking member 10 further includes a third spring 190, which is disposed between the outer wall of the disc 120 and the inner wall of the fastener 130, and its two ends are respectively connected to the disc 120 and the fastener 130. After the end of the second limiting member 180 is inserted into the first positioning hole 2102, the second end 1102 is rotated in the second direction opposite to the first direction. The disc 120 drives the fastener 130 to move closer to the second locking member 20. The fastener portion 1301 moves in the groove direction within the locking groove 2101. The end of the second limiting member 180 disengages from the first positioning hole 2102. Under the action of the third spring 190, the fastener 130 rotates relative to the disc 120 until the end of the first limiting member 150 extends out of the receiving hole 1201 and inserts into the notch of the fastener 130. The second end 1102 is continued to rotate in the second direction. The disc 120 drives the fastener 130 to rotate, causing the fastener portion 1301 to retract into the mounting groove 1601.

[0037] During unlocking, the second end 1102 is rotated in the second direction, opposite to the locking direction (first direction). The disc 120 reverses direction, causing the latch 130 to move closer to the second locking member 20. The latch portion 1301 moves towards the opening of the lock groove 2101. The second limiting member 180 retracts into the mounting base 160 under the action of the second spring 1801. Simultaneously, the latch 130 rotates relative to the disc 120 under the action of the third spring 190. Then, the fourth end 1402 of the first pushing member 140 is no longer subject to the lock base 210. When squeezed, the third end 1401 of the first pusher 140 loses its pushing and squeezing effect on the first limiting member 150, thereby causing the end of the first limiting member 150 to extend out of the receiving hole 1201 and insert into the notch of the fastener 130, so that the disc 120 and the fastener 130 can rotate together. Then, the second end 1102 is rotated in the second direction, and the disc 120 drives the fastener 130 to rotate, causing the fastener part 1301 to retract into the mounting groove 1601, thus completing the unlocking between the first lock member 10 and the second lock member 20, and enabling the two to be completely separated.

[0038] Furthermore, in other preferred embodiments of the present invention, the mounting base 160 is disposed within the support rod 30 of the display screen frame, the handle 110 is disposed on the surface of the support rod 30, the side of the support rod 30 facing the handle 110 is provided with a second positioning hole 301, and the second end 1102 is provided with a positioning pin 1103 that can extend into the second positioning hole 301.

[0039] Specifically, the mounting base 160 is fixedly connected to the frame 30 by screws, the handle 110 is disposed on the surface of the frame 30, and is fixedly connected to the disc by a pivot passing through the frame 30 and the mounting base 160. The second positioning hole 301 is disposed on the side of the frame 30 facing the handle 110. Generally, a second positioning hole 301 is provided on each side of the pivot of the handle 110. The two second positioning holes 301 are respectively used for the positioning pin 1103 at the second end 1102 position in the unlocked state and the locked state to be inserted to fix the handle 110, thereby preventing the handle 110 from being accidentally rotated.

[0040] It is conceivable that the locking seat 210 of the second locking member 20 is also connected to the support rod 30 of the other display frame by screws; in addition, by setting at least two first locking members 10 and second locking members 20 on the support rod 30, as shown by the dotted arrow in the figure, the reliability of the assembly connection between the two display frames can be effectively improved by locking the two pairs of first locking members 10 and second locking members 20 together.

[0041] 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.
