The locking member 34 is connected to the key cylinder 33 and rotates synchronously, and the locking member 34 has a locking position abutting against the rear side of the connection beam 51 to lock the display module main body 21 on the connection beam 51, and an unlocking position avoiding the connection beam 51 to enable the display module main body 21 to be separated from the cabinet 50. The interference piece 35 is rotatably sleeved on the key cylinder 33, the interference piece 35 and the locking piece 34 are arranged at intervals along the axial direction of the key cylinder 33, and the interference piece 35 has an interference position located on the front side of the connecting beam 51 to jack up the display module main body 21 and an avoidance position staggered from the connecting beam 51. The elastic linkage is provided between the locking member 34 and the interference member 35; wherein, when the locking member 34 is in the unlocking position, the interference member 35 is brought to the interference position by the elastic linkage member; when the lock member 34 rotates from the unlock position to the lock position, the interference member 35 rotates from the interference position to the escape position.

With the solution of the present embodiment, the locking member 34 is connected to the key cylinder 33 and rotates synchronously. The lock member 34 has a lock position abutting against the rear side of the connection beam 51 to lock the display module main body 21 on the connection beam 51, and an unlock position avoiding the connection beam 51 to enable the display module main body 21 to be separated from the cabinet 50. When operating from the front side of the LED display module 10, the tool 61 is used to drive the lock core 33 to rotate to lock the display module main body 21 on the connection beam 51 or separate the display module main body 21 from the cabinet 50. When operating at the rear side of the LED display module 10, the locking member 34 is directly driven to rotate to lock the display module main body 21 on the connection beam 51 or separate the display module main body 21 from the cabinet 50. The interference member 35 is rotatably sleeved on the key cylinder 33. And the interference piece 35 is arranged at an interval with the locking piece 34 along the axial direction of the key cylinder 33, and the interference piece 35 has an interference position located at the front side of the connection beam 51 to jack up the display module main body 21 and a relief position provided in a staggered manner from the connection beam 51. The elastic linkage piece is arranged between the locking piece 34 and the interference piece 35, so that the locking piece 34 drives the interference piece 35 to switch between an interference position and an avoidance position through elasticity or linkage; wherein, when the locking member 34 is in the unlocking position, the interference member 35 is brought to the interference position by the elastic linkage member; when the lock member 34 rotates from the unlock position to the lock position, the interference member 35 rotates from the interference position to the escape position. In-process on box 50 is installed to LED display module assembly 10 of LED display device, when locking piece 34 is in the unblock position, under the effect of elastic linkage piece elasticity, interference piece 35 is located the front side of tie-beam 51 in order to jack up display module assembly main part 21 for LED display device's front surface unevenness reminds operating personnel to drive lock core 33 in order to lock display module assembly main part 21 on tie-beam 51, avoids the emergence of missing the locking phenomenon. At this time, the tool 61 is used to drive the lock cylinder 33 to rotate or directly drive the locking member 34 to rotate, so that the locking member 34 is in the locking position, and under the action of linkage of the elastic linkage member, the interference member 35 rotates along with the locking member 34, the interference member 35 can be in the avoiding position, at this time, there is no interference between the LED display module 10 and the box 50, and since the interference member 35 is located in the avoiding position staggered from the connecting beam 51, the LED display device can be fixed on the box 50 and the front surface of the LED display device is flat. When the LED display module 10 needs to be removed from the box 50, the lock core 33 or the lock member 34 is driven to switch the lock member 34 from the lock position to the unlock position, and at this time, the interference member 35 rotates from the avoidance position to the interference position. However, since the LED display module 10 is not yet removed from the cabinet 50, the interference arm 352 abuts against the connection beam 51 of the cabinet 50 by the elastic link. When the LED display module 10 is removed from the box 50, after the locking member 34 moves forward a distance along with the display module main body 21, the side surface of the connecting beam 51 does not block the interference member 35, and the interference arm 352 rotates to the front side of the connecting beam 51 under the elastic force of the elastic linkage member, so that the interference member 35 is in the interference position. Therefore, the technical scheme of this embodiment has solved LED display module assembly among the correlation technique effectively and has installed the problem that the lock is missed to appear on the box through the tool to lock easily.

It should be noted that, the interference piece 35 is located at the avoiding position except the interference position, and the process of rotating the interference piece 35 from the interference position to the avoiding position can be realized by the above-mentioned linkage of the elastic linkage piece, and the locking piece 34 can drive the interference piece 35 to rotate together, or can be realized by a manual mode. Moreover, in the embodiment, the locking member 34 is in the shape of a handle, which facilitates the direct operation of the operator from the rear side of the LED display module 10 to lock the display module main body 21 on the connecting beam 51 or separate the display module main body 21 from the box 50.

In the correlation technique, because LED display module assembly is inhaled the structure through a plurality of magnetism and is installed on the box, because striking, high temperature, magnetic field influence, long-time reasons such as lead to ageing, there is the demagnetization hidden danger in magnet for LED display module assembly has the risk of dropping from the box.

In order to solve the above problem, as shown in fig. 1 to 9, the display module main body 21 of the present embodiment is mounted on the connecting beam 51 through a plurality of magnetic attraction structures 41. When locking piece 34 is in the unblock position, inhale LED display module assembly 10 magnetism to box 50 on, under the effect of elastic linkage piece, interfere 35 and be in and interfere the position, because interfere 35 this moment and be located the front side of tie-beam 51, with LED display module assembly 10 jack-up for LED display device's front surface unevenness reminds personnel to drive lock core 33 in order to lock display module assembly main part 21 on tie-beam 51, avoids the emergence of miss-lock phenomenon. At this time, the tool 61 is used again to drive the lock cylinder 33 to rotate or directly drive the locking piece 34 to rotate, so that the locking piece 34 is located at the locking position, and under the linkage action of the elastic linkage piece, the interference piece 35 is located at the avoiding position, at this time, the LED display module 10 is magnetically attracted onto the box body 50, and because the interference piece 35 is located at the avoiding position which is staggered with the connecting beam 51, the LED display device can be magnetically attracted onto the box body 50, and the front surface of the LED display device is flat. Because the locking piece 34 can lock the display module main body 21 on the connecting beam 51, the LED display module 10 can not fall off the box body 50 when the magnetic attraction fails, and the occurrence of a missing lock phenomenon can be avoided due to the arrangement of the interference piece 35. Therefore, the technical scheme of this embodiment has solved effectively that LED display device among the correlation technique uses magnetism to inhale the structure and when installing LED display module assembly on the box, LED display module assembly has the problem of the risk that drops from the box.

As shown in fig. 5 to 12, the interference member 35 includes a rotating sleeve 351 sleeved outside the lock cylinder 33 and an interference arm 352 connected to an outer side wall of the rotating sleeve 351, a first end of the elastic link member is connected to the locking member 34, and a second end of the elastic link member is connected to the interference arm 352. The LED display module 10 of the LED display device is mounted on the box 50 by using the magnetic attraction structure 41, and when the LED display module 10 needs to be removed from the box 50, the locking core 33 or the locking member 34 is driven to switch the locking member 34 from the locking position to the unlocking position, and at this time, the interference member 35 rotates from the avoiding position to the interference position. However, since the LED display module 10 is not yet removed from the housing 50, the interference arm 352 abuts against the connection beam 51 of the housing 50 by the elastic link. When the LED display module 10 is removed from the box 50, and the locking member moves forward with the LED display module 10 for a certain distance, the side surface of the connecting beam does not block the interference member 35, and the interference arm 352 rotates to the front side of the connecting beam 51 under the elastic force of the elastic linkage member, so that the interference member 35 is in the interference position. When attracting LED display module assembly 10 again to box 50 on, be in the position of interfering by interference piece 35, can jack-up LED display module assembly 10, realized the self-checking, play the guard action, avoid the emergence of miss-lock phenomenon.

The torsion spring 36 acts to allow the locking member 34 to develop a torsional force relative to the interference member 35, facilitating the interlocking engagement of the locking member 34 with the interference member 35 as the locking member 34 rotates. Meanwhile, the torsion spring 36 occupies a smaller space on the rear side of the LED display module 10, so that the LED display module 10 is more compact. In addition, the torsion spring 36 can keep the positions of the locking member 34 and the interference arm 352 relatively fixed without being subjected to an external force, in order to magnetically attract the LED display module 10 to the box 50, the locking member 34 first performs an operation of rotating from the unlocked position to the locked position, and in the process of rotating the locking member 34 from the unlocked position to the locked position, the locking member 34 drives the torsion spring 36 to rotate and enables the torsion spring 36 to interlock the interference arm 352, the interference arm 352 rotates along with the torsion spring 36, the interference arm 352 can rotate from the interference position to the avoidance position, and there is no interference between the LED display module 10 and the box 50, so that the LED display module 10 is magnetically attracted to the box 50.

In this embodiment, the LED display module 10 of the LED display device is mounted on the box 50 by using the magnetic attraction structure 41, and when the LED display module 10 needs to be removed from the box 50, the lock core 33 or the locking member 34 is driven to switch the locking member 34 from the locking position to the unlocking position, and at this time, the interference member 35 rotates from the avoiding position to the interference position. However, since the LED display module 10 is not yet removed from the cabinet 50, the interference arm 352 abuts against the connection beam 51 of the cabinet 50 by the torsion spring 36. When the LED display module 10 is removed from the cabinet 50, the interference arm 352 rotates to the front side of the connection beam 51 under the continued action of the torsion force of the torsion spring 36, and the interference piece 35 is maintained at the interference position. When the LED display module 10 is magnetically attracted to the box body 50, the interference piece 35 is located at the interference position, so that the LED display module 10 can be jacked up, and the phenomenon of lock missing is avoided. Wherein the locking member 34 has a detent bead 324 that is in detent engagement so that the locking member 34 does not move out of the unlocked position under the torque of the torsion spring 36.

As shown in fig. 5 to 12, the interference member 35 further includes a first driving block 353 connected to an outer side wall of the rotating sleeve 351, the first driving block 353 is spaced apart from the interference arm 352, and the locking member 34 includes a locking arm 342 and a second driving block 341 provided on a side of the locking arm 342 facing the rotating sleeve 351. The lock arm 342 has a lock position for locking the display module main body 21 to the connection beam 51 and an unlock position for separating the display module main body 21 from the cabinet 50. The interference arm 352 has a larger size extending in the radial direction of the rotating sleeve 351 than the first driving block 353, so that the first driving block 353 is not located at the front side of the connection beam 51 when the interference member 35 rotates, thereby not affecting the mounting of the LED display module 10 on the cabinet 50.

In this embodiment, the second driving block 341 is in driving engagement with the first driving block 353, so that the driving force applied by the second driving block 341 to the first driving block 353 is greater than the torsion force applied by the torsion spring 36 to the interference arm 352, so that when the locking member 34 rotates from the unlocking position to the locking position, the interference member 35 can be driven to rotate from the interference position to the avoiding position. Like this, because on LED display module assembly 10 will inhale the magnetism to box 50, there is great magnetic attraction between the two, when locking piece 34 switched to the locked position by the unblock position, the first driver block 353 rotation of interference piece 35 of second driver block 341 drive of locking piece 34 not only can overcome above-mentioned magnetic attraction, can also link torsional spring 36 and rotate together around lock core 33 to make interference piece 35 rotate. In this way, the interference member 35 can be quickly rotated from the interference position to the avoidance position in driving engagement of the first driving block 353 and the second driving block 341.

In the present embodiment, the center line of the first driving block 353 is disposed at 90 ° to the center line of the interference arm 352 on the orthographic projection plane in the axial direction of the sleeve 351 of the interference piece 35. Of course, in embodiments not shown in the figures, the center line of the first drive block 353 may also be disposed at 80 °, 83 °, 85 °, 87 °, 93 °, or 95 ° to the center line of the interference arm 352.

And a hollow through hole in a shape like a Chinese character 'kou' is enclosed between the two adjacent partial cross beams and the two adjacent partial longitudinal beams. The lock arm 342 is connected to the key cylinder 33 by a screw and rotates synchronously, and the lock arm 342 has a lock position for locking the display module main body 21 to the cross member and an unlock position for separating the display module main body 21 from the cross member.

As shown in fig. 3, 4 and 10 to 12, the key cylinder 33 includes a key disc 331 rotatably disposed at the key seat 32 and a core rod 332 penetrating the key disc 331, and a front portion of the core rod 332 is provided with a front operation hole 333. When operating from the front side of the LED display module 10, the tool 61 is used to extend into the front operating hole 333 to drive the lock core 33, so that the lock member 34 rotates to achieve locking of the display module main body 21 on the connection beam 51 or separation of the display module main body 21 from the cabinet 50. The rear of the core 332 is in anti-rotation engagement with the locking member 34 to allow the plug 33 to rotate simultaneously and angularly with the locking member 34.

In this embodiment, the display module main body 21 is provided with an avoiding hole corresponding to the front operation hole 333, and the tool 61 extends into the front operation hole 333 through the avoiding hole to drive the lock cylinder 33 to rotate. The display module assembly main part includes the backshell and sets up the lamp plate module at the backshell front side, and the lock seat setting of tool to lock is in the rear side of backshell, dodges the hole including setting up the first hole section on lamp plate module and the second hole section of setting on the backshell, and first hole section and second hole end intercommunication set up, and use tool 61 is passed through first hole section and second hole end and is stretched into preceding handle hole 333 in order to drive lock core 33 and rotate.
