[0019] In some embodiments, the toggle member is provided with a snap-fitting protrusion, and the handle assembly is provided with a snap-fitting groove, and the snap-fitting groove is snap-fitted with the snap-fitting protrusion, so that the handle assembly drives the toggle member to rotate and the toggle member moves relative to the handle assembly.

[0020] In some embodiments, the locking rod body is provided with a displacement scale mark, which is used to indicate the current extension length of the locking rod body relative to the locking sleeve assembly, and the difference between two adjacent scales in the displacement scale mark is equal to the spacing between two adjacent positioning holes.

[0021] In some embodiments, the LED display screen arc lock further includes a resisting member and a resisting elastic member, wherein the resisting elastic member is abutted between the lock sleeve assembly and the resisting member to provide elastic force to the resisting member so that the resisting member has a tendency to move close to the rotating member;

[0027] In some embodiments, both the locking sleeve assembly and the locking rod assembly are hinged with a connecting seat, and the connecting seat can rotate around an axis in the second direction.

[0028] Compared with the above background technology, the arc lock of the LED display screen provided in the embodiment of the present application includes a lock sleeve assembly, a lock rod assembly, a handle assembly, a rotating member, a positioning assembly, a limiter and a reset elastic member. The lock rod assembly can move in the lock sleeve assembly along a first direction; the handle assembly is rotatably connected to the lock sleeve assembly and can rotate around a second direction axis perpendicular to the first direction; the rotating member is engaged with the lock rod assembly and can rotate around the second direction axis to drive the lock rod assembly to move, and there is a limiter groove on it; the positioning assembly is clamped with the handle assembly and is matched with the rotating member, and can be embedded in the lock rod assembly for positioning, and can also rotate with the handle assembly and move relatively along the second direction axis to release the positioning; the limiter is provided in the positioning assembly, and in the first rotation stage, it moves along the limiter groove to make the positioning assembly disengage from the lock rod assembly, and in the second rotation stage, it drives the rotating member to rotate; the two ends of the reset elastic member abut the positioning assembly and the lock sleeve assembly, providing elastic force to make the positioning assembly tend to be embedded in the lock rod assembly.

[0029] During the arc adjustment operation, the positioning assembly is driven to rotate by the handle assembly. In the first rotation stage of the positioning assembly, the limit member moves in the limit groove, and the limit member pushes the positioning assembly to disengage from the locking rod assembly to release the positioning of the locking rod assembly; when the limit member is blocked in the limit groove and cannot move relative to the rotating member, the positioning assembly enters the second rotation stage, the limit member pushes the rotating member to rotate, and the rotating member drives the locking rod assembly to move relative to the locking sleeve assembly, and adjusts the curvature of the LED display to the required curvature.

[0030] The LED display screen arc lock set in this way has at least the following beneficial effects:

[0031] By rotating the single-handed operation handle assembly, the entire arc adjustment process of "unlock → adjust → lock" can be achieved. The operation is simple, the adjustment is convenient, and the efficiency is high. Specifically, in the first rotation stage of the positioning assembly, the limiting member moves along the limiting groove, pushing the positioning assembly away from the locking rod assembly to achieve unlocking; in the second rotation stage of the positioning assembly, after the limiting member is blocked, it pushes the rotating member to rotate, driving the locking rod assembly to move to achieve arc adjustment; after releasing the handle, the reset elastic member automatically pushes the positioning assembly to re-embed into the locking rod assembly to complete locking. At the same time, the cooperation between the limiting groove and the limiting member forms a physical hard limit, which not only ensures that the handle assembly can only drive the locking rod assembly to move within the preset angle range defined by the limiting groove, solving the problem of excessive adjustment error in the traditional technology, but also the positioning assembly can only be separated from the locking rod assembly under the push of the limiting member, preventing accidental unlocking under misoperation. In addition, the reset elastic member provides a flexible pressure (elastic force) to the positioning assembly when locking, realizing the automatic locking operation by releasing the handle assembly after adjusting to the target arc, and also avoiding the deformation of the box body of the LED display screen or damage to the LED display screen caused by traditional hard locking.

[0054] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] To enable those skilled in the art of this technology to better understand the solution of this application, the following further detailed description of this application will be given in conjunction with the accompanying drawings and specific embodiments.

[0056] The LED display screen arc lock provided by the embodiments of this application is used to adjust the arc of the LED display unit and fix the arc of the LED display unit. Among them, the LED display unit is composed of a plurality of mutually hinged LED display modules. By being mutually hinged, the angle between adjacent LED display modules can be changed, so that the LED display module can change the arc and achieve flexibility.

[0057] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown in, the LED display screen arc lock includes a lock sleeve assembly 10, a lock rod assembly 20, a handle assembly 60, a rotating member 30, a positioning assembly 40, a limiting member 50, and a reset elastic member 70.

[0058] The lock rod assembly 20 is movably embedded in the lock sleeve assembly 10, and the lock rod assembly 20 can move in the lock sleeve assembly 10 along a first direction. By moving the lock rod assembly 20 relative to the lock sleeve assembly 10, the protruding length of the lock rod assembly 20 relative to the lock sleeve assembly 10 is changed to adjust the arc of the LED display unit.

[0059] The handle assembly 60 is rotatably connected to the lock sleeve assembly 10. The handle assembly 60 can rotate around its own axis, and the axis is parallel to a second direction, and the second direction is perpendicular to the first direction.

[0060] Among them, the so-called first direction can be the X-axis direction as shown in Figure 1 , and the second direction can be the Y-axis direction as shown in Figure 1 .

[0061] The rotating member 30 is engaged with the lock rod assembly 20. The rotating member 30 can rotate around its own axis to drive the lock rod assembly 20 to move. The axis is parallel to the second direction, and a limiting groove 31 is provided on the rotating member 30.

[0062] The positioning assembly 40 is clamped to the handle assembly 60. The positioning assembly 40 is penetrated and matched with the rotating member 30. The positioning assembly 40 can be embedded in the lock rod assembly 20 to realize the positioning of the lock rod assembly 20. Moreover, the positioning assembly 40 can also rotate with the handle assembly 60 and move relatively along the axis of the second direction to release the positioning of the lock rod assembly 20.

[0063] The limiting member 50 is provided on the positioning assembly 40. The limiting member 50 is used to move along the limiting groove 31 in the first rotation stage of the positioning assembly 40 to disengage the positioning assembly 40 from the lock rod assembly 20. The limiting member 50 is also used to push the rotating member 30 to rotate in the second rotation stage of the positioning assembly 40, thereby driving the lock rod assembly 20 to move.

[0064] The reset elastic member 70 can be a reset spring. The two ends of the reset elastic member 70 respectively abut against the positioning assembly 40 and the lock sleeve assembly 10. The reset elastic member 70 is used to provide an elastic force so that the positioning assembly 40 has a tendency to embed into the lock rod assembly 20. In this way, it is beneficial for the positioning assembly 40 to automatically reset and embed into the lock rod assembly 20 after the handle assembly 60 is released after the arc adjustment is completed, realizing the repositioning of the lock rod assembly 20.

[0065] During the arc adjustment operation, the handle assembly 60 drives the positioning assembly 40 to rotate. In the first rotation stage of the positioning assembly 40, the limiting member 50 moves in the limiting groove 31, and the limiting member 50 pushes the positioning assembly 40 away from the lock rod assembly 20 to release the positioning of the lock rod assembly 20; when the limiting member 50 is blocked in the limiting groove 31 and cannot move relative to the rotating member 30, the positioning assembly 40 enters the second rotation stage, and the limiting member 50 pushes the rotating member 30 to rotate. The rotating member 30 drives the lock rod assembly 20 to move relative to the lock sleeve assembly 10, and adjusts the arc of the LED display screen to the required arc. When the target arc is adjusted, the handle assembly 60 is released. Under the action of the elastic force of the reset elastic member 70, the positioning assembly 40 embeds into the lock rod assembly 20 to realize the positioning of the lock rod assembly 20, thereby completing the arc adjustment operation of the LED display screen.

[0066] With such a setting, by rotating the handle assembly 60 with one hand, the entire arc adjustment process of "unlock → adjust → lock" can be realized. The operation is simple, the adjustment is convenient, and the efficiency is high. Specifically, in the first rotation stage of the positioning assembly 40, the limiting member 50 moves along the limiting groove 31 and pushes the positioning assembly 40 away from the lock rod assembly 20 to realize unlocking; in the second rotation stage of the positioning assembly 40, after the limiting member 50 is blocked, it pushes the rotating member 30 to rotate, driving the lock rod assembly 20 to move to realize arc adjustment; after the handle is released, the reset elastic member 70 automatically pushes the positioning assembly 40 to re-embed into the lock rod assembly 20 to complete locking. At the same time, the cooperation between the limiting groove 31 and the limiting member 50 forms a physical hard limit, which not only ensures that the handle assembly 60 can only drive the lock rod assembly 20 to move within the preset angle range defined by the limiting groove 31, solving the problem of excessive adjustment error in the traditional technology, but also the positioning assembly 40 needs to be pushed by the limiting member 50 to be separated from the lock rod assembly 20 to prevent accidental unlocking under misoperation. In addition, the reset elastic member 70 provides a flexible pressure (elastic force) to the positioning assembly 40 during locking, realizing the automatic locking operation by releasing the handle assembly 60 after adjusting to the target arc, and also avoiding the deformation of the box body of the LED display screen or damage to the LED display screen caused by traditional hard locking.

[0067] Please refer to Figure 4 、 Figure 5 and Figure 6The lock rod assembly 20 includes a lock rod body 21 and a positioning member 22. In order to facilitate the engagement between the lock rod body 21 and the rotating member 30, the lock rod body 21 is provided with a rack 211 engaged with the rotating member 30, and the rotating member 30 is provided with a gear portion 33 engaged with the rack 211, and the gear portion 33 is accommodated in the lock rod body 21; the positioning member 22 is connected to the lock rod body 21 through a fastener, and the positioning member 22 is accommodated in the lock rod body 21. In this way, the positioning member 22 is embedded in the positioning assembly 40 to achieve the purpose of positioning the lock rod body 21.

[0068] Specifically, the positioning member 22 can be a positioning plate structure, and the positioning member 22 is provided with positioning holes 221 spaced apart along the first direction. The spacing between two adjacent positioning holes 221 can be set to be the same. After the arc adjustment is completed, the positioning assembly 40 is embedded in the positioning hole 221 to limit the movement of the locking rod body 21, thereby achieving the purpose of positioning the locking rod body 21.

[0069] Please also read Figure 9 and Figure 10 The positioning assembly 40 includes a positioning pin 41 and a toggle member 42. The positioning pin 41 passes through the rotating member 30, and the positioning pin 41 is provided with an embedding end 411 that matches the positioning hole 221. The embedding end 411 is an embedding end 411 with a certain taper, so that the tip of the embedding end 411 can be smoothly embedded in the positioning hole 221; the toggle member 42 is connected to the positioning pin 41, and is used to drive the positioning pin 41 to disengage from the positioning hole 221 to release the positioning of the lock rod body 21.

[0070] In order to facilitate the connection between the toggle member 42 and the positioning pin 41, the toggle member 42 is provided with an axial connection hole, and the positioning pin 41 is interference fitted in the connection hole to achieve synchronous movement of the toggle member 42 and the positioning pin 41 during the arc adjustment process.

[0071] To facilitate installation of the resetting elastic member 70 , an annular protrusion is provided at one end of the toggle member 42 close to the positioning member 22 . One end of the resetting elastic member 70 abuts against the inner side of the annular protrusion, and the other end abuts against the inner wall of the lock sleeve assembly 10 .

[0072] In this way, when the handle assembly 60 drives the toggle member 42 to rotate, under the cooperation of the limit member 50 and the limit groove 31, the limit member 50 pushes the positioning pin 41 out of the positioning hole 221 to release the positioning of the locking rod body 21. In the process of releasing the positioning, the reset elastic member 70 accumulates elastic potential energy; continue to rotate the handle assembly 60, the limit member 50 drives the rotating member 30 to rotate, and the rotating member 30 drives the locking rod body 21 to move relative to the locking sleeve assembly 10, so as to achieve the purpose of arc adjustment. After the arc adjustment is completed, release the toggle member 42, and the elastic potential energy accumulated by the reset elastic member 70 is released, so that the positioning pin 41 automatically resets and embeds into the positioning hole 221, thereby realizing the repositioning of the locking rod body 21.

[0073] In some embodiments, the toggling member 42 is provided with a clamping protrusion 421, and the handle assembly 60 is provided with a clamping groove 61. The clamping protrusion 421 is movably fitted in the clamping groove 61 so that the handle assembly 60 drives the toggling member 42 to rotate and the toggling member 42 moves relative to the handle assembly 60.

[0074] That is to say, through the clamping cooperation between the clamping protrusion 421 and the clamping groove 61, while transmitting the torque of the handle assembly 60 to the toggling member 42, the toggling member 42 can also axially move relative to the handle assembly 60, so as to achieve the purpose of unlocking.

[0075] To facilitate accurately controlling the length that the lock rod body 21 extends relative to the lock sleeve assembly 10, the lock rod body 21 is provided with a displacement scale mark 212. The displacement scale mark 212 is used to indicate the current length that the lock rod body 21 extends relative to the lock sleeve assembly 10. The difference between two adjacent scales in the displacement scale mark 212 is equal to the distance between two adjacent positioning holes 221.

[0076] Please refer to Figure 5 、 Figure 6 and Figure 8 , the LED display arc lock further includes a pressing member 80 and a pressing elastic member 90. The pressing elastic member 90 is abutted between the lock sleeve assembly 10 and the pressing member 80 to provide an elastic force to the pressing member 80, so that the pressing member 80 has a tendency to move closer to the rotating member 30.

[0077] For this reason, the rotating member 30 is provided with pressing holes 32 evenly distributed in the circumferential direction. The pressing member 80 is in positioning cooperation with the pressing holes 32. Among them, the pressing member 80 is in a spherical shape, the pressing holes 32 are round holes, and the pressing elastic member 90 is a pressing spring.

[0078] In this way, when adjusted to the required arc, the pressing member 80 rotates from the previous pressing hole 32 to the next pressing hole 32, and a predetermined sound and a predetermined sense of force will be generated, so as to provide feedback of sound and strength to the operator.

[0079] At the same time, the lock rod body 21 is configured to extend one unit scale of the displacement scale mark 212 relative to the lock sleeve assembly 10 when the pressing member 80 passes between two adjacent pressing holes 32. In this way, it is convenient to further accurately control the length that the lock rod body 21 extends relative to the lock sleeve assembly 10.

[0080] Please refer to Figure 7The limiting groove 31 may be a combined spiral groove. Specifically, the limiting groove 31 includes a first spiral groove 311 and a second spiral groove 312. The first spiral groove 311 and the second spiral groove 312 both have a first position and a second position. The first spiral groove 311 and the second spiral groove 312 are connected at the first position. When the limiting member 50 is in the first position, the positioning assembly 40 is embedded in the locking rod assembly 20. When the limiting member 50 is in the second position, the positioning assembly 40 is separated from the locking rod assembly 20. Of course, the limiting member 50 is specifically a limiting bead.

[0081] It should be noted that the first position is the highest point of the first spiral groove 311 or the second spiral groove 312 , and correspondingly, the second position is the lowest point of the first spiral groove 311 or the second spiral groove 312 .

[0082] In this way, when the locating pin 41 is embedded in the locating hole 221, the limit member 50 is located at the highest point position of the first spiral groove 311 or the second spiral groove 312. As the toggle member 42 enters the first rotation stage, the limit member 50 moves along the spiral groove from the highest point position to the lowest point position. When the limit member 50 reaches the lowest point position, the locating pin 41 disengages from the locating hole 221 to achieve unlocking. Thereafter, the toggle member 42 enters the second rotation stage. Since the limit member 50 is blocked at the lowest point position of the spiral groove and cannot continue to rotate relative to the rotating member 30, it can only push the rotating member 30 to rotate together to achieve the movement of the locking rod body 21. After the arc adjustment is completed, the toggle member 42 is released, and the locating pin 41 is reset under the elastic force of the reset elastic member 70 and is re-embedded in the other locating holes 221. At this time, the limit member 50 returns to the highest point position along the spiral groove from the lowest point position.

[0083] It should be noted that, during the process of unlocking and relocking the positioning pin 41, the limiting member 50 only moves in one spiral groove in both positive and negative directions. The purpose of setting another spiral groove is that when the limiting member 50 is at the highest point of the first spiral groove 311 or the second spiral groove 312, the operator can rotate the toggle member 42 in both clockwise and counterclockwise directions. For example, when rotating in the clockwise direction, the limiting member 50 moves from the highest point to the lowest point along the first spiral groove 311, and when rotating in the counterclockwise direction, the limiting member 50 moves from the highest point to the lowest point along the second spiral groove 312.

[0084] In some embodiments, the lock sleeve assembly 10 includes a first slide cover 11 and a second slide cover 12, which are combined to form a sliding track, and the lock rod assembly 20 slides under the guidance and limiting action of the sliding track. In this way, the movement of the lock rod body 21 relative to the lock sleeve assembly 10 can be guided and limited during the arc adjustment process, thereby ensuring the stability of the movement of the lock rod body 21.

[0085] In addition, the second sliding cover 12 is provided with a mounting groove 121 and a through hole 122. The mounting groove 121 is located inside the through hole 122. The rotating member 30 is installed in the mounting groove 121. The through hole 122 communicates with the mounting groove 121 in the second direction. The positioning assembly 40 passes through the through hole 122.

[0086] In this way, the rotating member 30 can rotate in the mounting groove 121, which is beneficial to protecting the rotating member 30 and ensuring the adjustment accuracy and service life of the adjustment module.

[0087] In some embodiments, locking sleeve assemblies 10 are respectively connected to both ends of the handle assembly 60. The second sliding cover 12 is provided with a rotating connection protrusion 123, and the handle assembly 60 is provided with a rotating connection groove 62. The rotating connection protrusion 123 is embedded in the rotating connection groove 62 so that the handle assembly 60 can rotate relative to the second sliding cover 12.

[0088] In this way, the entire LED display screen arc lock has an I-shaped structure. During the arc adjustment operation, the positioning assemblies 40 at the upper and lower ends are driven to rotate by the handle assembly 60. In the first rotation stage, the limiting member 50 pushes the positioning assembly 40 away from the corresponding lock rod assembly 20 to achieve unlocking. In the second rotation stage, the limiting member 50 pushes the rotating member 30 to rotate, and the rotating member 30 drives the lock rod assembly 20 to move relative to the corresponding locking sleeve assembly 10, and adjusts the arc of the LED display screen to the required arc. When the target arc is adjusted, the handle assembly 60 is released. Under the elastic force of the reset elastic member 70, the positioning assembly 40 is embedded in the corresponding lock rod assembly 20 to reposition the lock rod assembly 20, thereby completing the arc adjustment operation of the LED display screen.

[0089] In addition, connection seats 100 are hinged to both the locking sleeve assembly 10 and the lock rod assembly 20, and the connection seats 100 can rotate around an axis parallel to the second direction.

[0090] Specifically, the LED display screen box body includes a left side frame assembly and a right side frame assembly. The number of LED display screen arc locks is also two, namely the left LED display screen arc lock and the right LED display screen arc lock. Among them, the left and right ends of the LED display unit are respectively connected to the left side frame assembly and the right side frame assembly. One end of the left LED display screen arc lock is connected to the left side frame assembly through the connection seat 100, and the other end can be connected to the middle central control box assembly through the connection seat 100. One end of the right LED display screen arc lock is connected to the right side frame assembly through the connection seat 100, and the other end can be connected to the middle central control box assembly through the connection seat 100.

[0091] Working principle: First, install two LED display arc locks on the LED display box body. During the arc adjustment operation, just turn the handle assembly 60 with one hand. In the first rotation stage, the lock rod assembly 20 is switched from the locked state to the unlocked state. In the second rotation stage, the lock rod assembly 20 moves relative to the lock sleeve assembly 10 to achieve arc adjustment.
