a base;

The present application further provides a LED module, including:

a support;

the display screen is fixed on the bracket;

the switch lock is arranged at one end of the central control box and used for fixing or detaching the central control box from the bracket.

Above-mentioned switch lock that provides is through rotationally locating the base with first closure and second closure to when accuse box locking is on the support in with, need promote earlier the promotion portion so that the opening part of second closure chucking on promotion portion just can realize the fixed of accuse box and support in. When the central control box needs to be detached from the support, the second locking piece needs to be pressed first to enable the first locking piece to be separated from the opening on the pushing portion, so that the central control box can be separated from the support, and the problem that locking is not firm due to the fact that a spring is weak due to locking of a single spring is solved.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1 and 2, the present application provides an LED module 100, which includes a bracket 10 and a display screen (not shown) disposed on the bracket 10. The stand 10 is used to face a display screen in a designated direction to display a specific image and video information.

It should be noted that the above-described support 10 may be applied to the outside of a building wall for advertising purposes, or in special cases such as a high-speed rail station for displaying the arrival information of a specific high-speed rail. But obviously, the method is not limited to the method and can be applied to other occasions needing to use the display screen.

Further, in the display screen, in order to monitor the information displayed on the display screen and install the flat cable of the circuit, etc., the LED module 100 further includes a central control box 20. Wherein, well accuse box 20 detachably locates the one side that support 10 deviates from the display screen to when the display screen shows, hide well accuse box 20, thereby increase the visual effect of seeing the shadow.

It should be noted that, when the traditional central control box 20 is used, the central control box 20 is usually connected to the bracket 10 through a spring, and the spring will be fatigued after being used for a long time, so as to cause the problem that the central control box 20 is loose or not fixed firmly, and therefore, the LED module 100 further includes a switch lock 30, and the switch lock 30 is disposed at one end of the central control box 20, and is used for fixing or detaching the central control box 20 from the bracket 10.

Referring to fig. 3-5, the switch lock 30 includes a base 31, and a first locking member 32 and a second locking member 33 rotatably disposed on the base 31. Further, the first locking element 32 includes a pushing portion 321, a rotating portion 322 and a locking portion 323, which are connected to each other, and the pushing portion 321 has an opening 3211, and the rotating portion 322 is rotatably disposed on the base 31. Further, the second locking element 33 is disposed opposite to the opening 3211, so that the pushing portion 321 can be clamped or released in the opening 3211 to fix or detach the console box 20 and the rack 10. According to the scheme, the first locking piece 32 and the second locking piece 33 are arranged at the same time, and the central control box 20 is fixed or detached on the support 10 through the clamping fit of the first locking piece 32 and the second locking piece 33, so that the problem that the central control box 20 is loosened due to loose fixation caused by loose fixation when the spring is weak due to independent use of the spring is avoided.

In one embodiment, the pushing portion 321, the rotating portion 322 and the locking portion 323 are integrally formed.

In one embodiment, the locking portion 323 has a substantially L-shaped latching structure to latch into a latching opening (not shown) of the rack 10 during rotation, so as to connect the console box 20 and the rack 10.

It should be noted that, in the above solution, the opening 3211 is disposed on the pushing portion 321, and the second locking element 33 is disposed opposite to the opening 3211, so that when the first locking element 32 and the second locking element 33 are locked, the second locking element 33 is overlapped with the first locking element 32, thereby avoiding a problem of space waste caused by disposing the second locking element 33 outside the first locking element 32, and thus reducing the use of materials, reducing the space volume occupied by the switch lock 30, and facilitating the manufacture of the LED module 100 to be smaller.

To facilitate the fixing and detaching of the second locking element 33 from the opening 3211 of the first locking element 32, the first locking element 32 further includes a locking portion 324 disposed in the opening 3211. Further, the fastening portion 324 has a first surface 3241 and a second surface 3242 disposed oppositely, and preferably, the first surface 3241 is located above the second surface 3242. The second locking element 33 has a third surface 331 and a fourth surface 332 connected to each other, and preferably, the third surface 331 and the fourth surface 332 are disposed at an angle.

As can be seen from fig. 3 to 5, fig. 3 illustrates a state before the switch lock 30 is locked, at this time, the first locking element 32 is separated from the second locking element 33, that is, the second locking element 33 is separated from the locking portion 324, and at this time, the locking portion 323 is inclined forward and downward (forward and downward as shown in the figure), so that the locking portion 323 is conveniently separated from the locking opening on the bracket 10. At this time, the first surface 3241 and the second surface 3242 are positioned above the third surface 331 and the fourth surface 332.

Referring to fig. 4 and 5, fig. 4 and 5 show a state of the switch lock 30 when being locked in the engaging opening of the bracket 10, at this time, the second locking element 33 is clamped on the clamping portion 324 of the first locking element 32, that is, the first surface 3241 abuts on the third surface 331, so that under the limit of the first locking element 32, the second locking element 33 cannot break through the first locking element 32 to separate the console box 20 from the bracket 10, thereby increasing the fixing tightness of the console box 20 and the bracket 10.

It should be noted that when the first locking element 32 is separated from the second locking element 33, the second face 3242 can be separated from the fourth face 332 (see fig. 3), and the second face 3242 can also be attached to the fourth face 332.

Further, when the first locking element 32 and the second locking element 33 are locked, the first face 3241 and the second face 3242 are parallel to a horizontal plane. It should be noted that, during the use of the LED module 100, the console box 20 is generally vertically fixed on the support 10. When the second locking element 33 is separated from the opening 3211 of the first locking element 32, since the second locking element 33 needs to rotate along the axis of rotation thereof, there is an upward force on the first locking element 32 by the second locking element 33 at the contact position of the first locking element 32 and the second locking element 33, and at this time, when the first surface 3241 and the third surface 331 are disposed obliquely, the first surface 3241 and the third surface 331 are easily separated. When the first surface 3241 and the third surface 331 are disposed along the horizontal direction, at this time, there is a movement interference between the first locking element 32 and the second locking element 33, so that the second locking element 33 cannot easily pass over the first locking element 32, and thus the problem that the console box 20 is separated from the rack 10 occurs.

Still further, in order to facilitate the engagement of the first locking member 32 and the second locking member 33, the base 31 includes a bottom plate 311, a first support plate 312 extending upward from the bottom plate 311, and a second support plate 313 extending downward from the bottom plate 311. Specifically, the first locking element 32 is rotatably disposed on the first support plate 312, and the second locking element 33 is rotatably disposed on the second support plate 313. Referring specifically to fig. 3-5, the first locking element 32 and the second locking element 33 are disposed across the opening 3211 to facilitate the overlapping arrangement of the first locking element 32 and the second locking element 33, so as to reduce the volume of the switch lock 30.

Further, in order to facilitate the fixing of the switch lock 30 to the hollow box, the base 31 further includes a fixing portion 314 provided at an upper end of the first support plate 312. Preferably, the fixing portion 314 is opened with a second fixing hole 3141, and the fixing portion 314 can be fixed on the console box 20 through the second fixing hole 3141. In one embodiment, a plurality of second fixing holes 3141 are drilled through by screws to fix the fixing portion 314 to the console box 20.

In order to rotatably mount the first locking element 32 on the first supporting plate 312, the switch lock 30 further includes a first connecting member 34, a first through hole 3221 is formed in the extended thickness direction of the rotating portion 322, and two first connecting holes 3121 are formed in the first supporting plate 312 and are opposite to each other. Specifically, the first connecting element 34 is disposed through the first through hole 3221, and the two first connecting elements 34 respectively extend into the two first connecting holes 3121, so that the first locking element 32 rotates around the first connecting element 34.

In one embodiment, the first connector 34 includes, but is not limited to, a connecting shaft or the like.

Further, in order to prevent the first locking element 32 and the second locking element 33 from loosening during locking, the switch lock 30 further includes a first torsion spring 35, and the base 31 is provided with two first fixing holes 3122 disposed oppositely. Specifically, the first torsion spring 35 is sleeved on the first connecting member 34, and one end of the first torsion spring 35 extends into the first fixing hole 3122, and the other end of the torsion spring abuts on the rotating portion 322, so that when the first surface 3241 of the clamping portion 324 abuts on the third surface 331 of the second locking member 33, the first torsion spring 35 pushes the rotating portion 322 and tightly abuts on the third surface 331 of the first surface 3241, thereby ensuring the connecting strength between the first locking member 32 and the second locking member 33, and preventing the first locking member 32 and the second locking member 33 from loosening due to external force or shaking.

Further, in order to rotatably arrange the second locking member 33 on the second supporting plate 313, the switch lock 30 further includes a second connecting member 36, the second locking member 33 has a second through hole 333 along the thickness direction thereof, and the second supporting plate 313 has two second connecting holes 3131 disposed oppositely. Specifically, the second connecting member 36 is inserted into the second through hole 333, and two ends of the second connecting member 36 respectively extend into the two second connecting holes 3131. So that the second locking element 33 can rotate around the second connecting element 36 to achieve the clamping or the loosening of the first locking element 32 and the second locking element 33.

In one embodiment, the second connector 36 includes, but is not limited to, a connecting shaft or the like.

Still further, in order to better solve the problem of the first locking element 32 and the second locking element 33 loosening during locking, the switch lock 30 further comprises a second torsion spring 37. Specifically, the second torsion spring 37 is sleeved on the second connecting member 36, one end of the second torsion spring 37 abuts against the bottom plate 311, and the other end of the second torsion spring 37 abuts against the second locking member 33, so that when the first locking member 32 and the second locking member 33 are locked, the second torsion spring 37 applies a force to the second locking member 33 in a direction toward the first locking member 32, and in combination with the force applied to the first locking member 32 in a direction toward the second locking member 33 by the first torsion spring 35, the first torsion spring 35 and the second torsion spring 37 clamp the first locking member 32 and the second locking member 33, thereby preventing the first locking member 32 and the second locking member 33 from being separated due to external force and shaking, and increasing the stability of the connection between the first locking member 32 and the second locking member 33.

The specific operation flow of an embodiment of the present application is as follows: in the process of assembling or disassembling the central control box 20 to or from the bracket 10 of the LED module 100, firstly, the lower end of the central control box 20 abuts against the lower end of the bracket 10, and the central control box 20 is rotated along the abutting position, and when the central control box 20 drives one end of the switch lock 30 to be contacted with the bracket 10, the pushing part 321 is pressed downwards along the vertical direction, so that the clamping part 324 passes over the second locking part 33. At this time, the pushing portion 321 is released, the pushing portion 321 is driven by the first torsion spring 35 to bounce upwards, the second torsion spring 37 gives a force to the second locking member 33 in a direction toward the first locking member 32, and at this time, the first torsion spring 35 and the second torsion spring 37 press the first locking member 32 and the second locking member 33, so that the first surface 3241 is tightly attached to the third surface 331. In the process, the locking part 323 rotates along with the rotating part 322 along with the pushing part 321 until the locking part 323 approaches to the opening and closing part on the bracket 10 and is clamped in the opening and closing part, so that the central control box 20 and the bracket 10 are fixed.

When the center control box 20 needs to be removed from the bracket 10, the second locking piece 33 is pressed to enable the second locking piece 33 to pass over the clamping part 324, the first locking piece 32 and the second locking piece 33 are separated under the driving of the first torsion spring 35 and the second torsion spring 37, and at the moment, the locking part 323 is separated from the opening and closing opening on the bracket 10, so that the center control box 20 is separated from the bracket 10.

In the above manner, the central control box 20 and the support 10 can be fixed or separated by pressing the pushing portion 321 or the second locking member 33, and due to the pushing force of the first torsion spring 35 and the second torsion spring 37, the first locking member 32 and the second locking member 33 are locked firmly and cannot be easily separated due to the influence of external force, so that the stability of the connection between the central control box 20 and the support 10 is ensured, and the problem that the central control box 20 and the support 10 are loosened and the central control box 20 falls off due to the connection of a single spring and the long-term use fatigue of the spring is avoided.

While the foregoing is directed to embodiments of the present application, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims.
