[0040] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0041] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component. When a component is considered to be "located on" another component, it can be directly located on the other component or there may be an intermediate component. The terms "top", "bottom", "

[0042] "Up," "down," "left," "right," "front," "back," and similar expressions are for illustrative purposes only.

[0043] An embodiment of the present application provides a switch lock, which is provided on a central control box and is used to fix the central control box on a bracket, including:

[0044] base;

[0045] A first locking member includes a pushing portion, a rotating portion, and a locking portion connected to each other, wherein the rotating portion is rotatably disposed on the base, and the pushing portion has an opening;

[0046] a second locking member rotatably disposed on the base, and the second locking member is disposed opposite the opening;

[0047] When the pushing part is pushed to rotate along the rotating part, the second locking part can be clamped in the opening so that the locking part is locked on the bracket. When the second locking part is pressed to rotate, the second locking part disengages from the opening so that the locking part and the bracket are loosened.

[0048] The present application also provides an LED module, comprising:

[0049] Bracket;

[0050] A display screen is fixed on the bracket;

[0051] a central control box, detachably arranged on a side of the bracket facing away from the display screen;

[0052] The switch lock described above is provided at one end of the central control box and is used to fix or detach the central control box from the bracket.

[0053] The switch lock provided above features a first locking member and a second locking member rotatably mounted on the base. When locking the central control box to the bracket, the push portion must first be pushed to engage the second locking member with an opening in the push portion to secure the central control box to the bracket. Furthermore, when detaching the central control box from the bracket, the second locking member must first be pressed to disengage the first locking member from the opening in the push portion to separate the central control box from the bracket. This avoids the problem of loose locking caused by a weak spring in a single spring lock.

[0054] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0055] See also Figure 1 and Figure 2 The present application provides an LED module 100, comprising a bracket 10 and a display screen (not shown) disposed on the bracket 10. The bracket 10 is used to direct the display screen toward a specified direction to display specific images and video information.

[0056] It should be noted that the bracket 10 can be applied to the outside of a building wall for advertising or in special occasions, such as a high-speed rail station to display specific high-speed rail arrival information. However, it is obviously not limited to this and can also be applied to other occasions where a display screen is required.

[0057] Furthermore, in order to monitor the information displayed on the display and install and route circuits, the LED module 100 also includes a central control box 20. The central control box 20 is detachably mounted on the side of the bracket 10 facing away from the display screen. When the display screen is in use, the central control box 20 is hidden, thereby enhancing the visual effect of the viewing experience.

[0058] It should be noted that when a traditional central control box 20 is used, the central control box 20 is often connected to the bracket 10 through a spring. When the spring is used for a long time, it will become weak, which will cause the central control box 20 to become loose or not firmly fixed. Therefore, the LED module 100 also includes a switch lock 30. The switch lock 30 is provided at one end of the central control box 20 and is used to fix or detach the central control box 20 from the bracket 10.

[0059] See also Figure 3-Figure 5 The switch lock 30 includes a base 31 and a first locking member 32 and a second locking member 33 rotatably mounted on the base 31. Furthermore, the first locking member 32 includes a push portion 321, a rotating portion 322, and a locking portion 323 that are interconnected. The push portion 321 has an opening 3211, and the rotating portion 322 is rotatably mounted on the base 31. Furthermore, the second locking member 33 is positioned opposite the opening 3211, thereby pushing the push portion 321 to tighten or loosen within the opening 3211 to secure or detach the central control box 20 from the bracket 10. The above solution, by simultaneously providing the first locking member 32 and the second locking member 33 and by means of the tightening engagement of the first locking member 32 and the second locking member 33, secures or detaches the central control box 20 from the bracket 10, thereby avoiding the problem of using a single spring, which, when the spring becomes weak, may cause the central control box 20 to become loose due to a loose fixation.

[0060] In one embodiment, the pushing portion 321 , the rotating portion 322 and the locking portion 323 are integrally formed.

[0061] In one embodiment, the locking portion 323 is a substantially L-shaped block structure, which is engaged with a locking opening (not shown) on the bracket 10 during the rotation process to achieve the connection between the central control box 20 and the bracket 10.

[0062] It should be noted that, in the above scheme, an opening 3211 is provided on the pushing portion 321, and the second locking member 33 is provided opposite to the above opening 3211, so that when the first locking member 32 and the second locking member 33 are locked, the second locking member 33 overlaps with the first locking member 32, thereby avoiding the problem of space waste caused by providing the second locking member 33 outside the first locking member 32, thereby reducing the use of materials and reducing the space volume occupied by the switch lock 30, thereby facilitating the manufacture of a smaller LED module 100.

[0063] To facilitate the attachment or detachment of the second locking member 33 to or from the opening 3211 of the first locking member 32, the first locking member 32 further includes a clamping portion 324 disposed within the opening 3211. Furthermore, the clamping portion 324 has a first surface 3241 and a second surface 3242 disposed opposite each other. Preferably, the first surface 3241 is located above the second surface 3242. The second locking member 33 has a third surface 331 and a fourth surface 332 connected to each other. Preferably, the third surface 331 and the fourth surface 332 are disposed at an angle.

[0064] Please combine Figure 3-Figure 5 It can be seen that Figure 3This is the state before the switch lock 30 is locked. At this time, the first locking member 32 and the second locking member 33 are separated, that is, the second locking member 33 is separated from the clamping portion 324. At this time, the locking portion 323 is tilted forward and downward (front and downward as shown in the figure), thereby facilitating the locking portion 323 to disengage from the clamping opening on the bracket 10. At this time, the first surface 3241 and the second surface 3242 are located above the third surface 331 and the fourth surface 332.

[0065] See also Figure 4 and Figure 5 , Figure 4 and Figure 5 The diagram shows the state of the switch lock 30 when it is locked in the locking opening of the bracket 10. At this time, the second locking member 33 is clamped on the clamping portion 324 on the first locking member 32, that is, the first surface 3241 abuts against the third surface 331, so that under the limit of the first locking member 32, the second locking member 33 cannot break through the first locking member 32 to separate the central control box 20 from the bracket 10, thereby increasing the fastening of the central control box 20 and the bracket 10.

[0066] It should be noted that when the first locking member 32 is separated from the second locking member 33, the second surface 3242 can be separated from the fourth surface 332 (see Figure 3 ), the second surface 3242 can also be attached to the fourth surface 332.

[0067] Furthermore, when the first locking member 32 and the second locking member 33 are locked, the first surface 3241 and the second surface 3242 are parallel to the horizontal plane. It should be noted that during use of the LED module 100, the central control box 20 is generally fixed vertically to the bracket 10. Furthermore, when the second locking member 33 is disengaged from the opening 3211 of the first locking member 32, since the second locking member 33 needs to rotate along its rotation axis, an oblique upward force is exerted on the first locking member 32 at the contact point between the first and second locking members 32 and 33. At this time, when the first surface 3241 and the third surface 331 are arranged at an angle, the first surface 3241 and the third surface 331 can be easily disengaged. When the first surface 3241 and the third surface 331 are arranged in the horizontal direction, at this time, due to the movement interference between the first locking member 32 and the second locking member 33, the second locking member 33 cannot easily pass over the first locking member 32, resulting in the problem of the central control box 20 being detached from the bracket 10.

[0068] Furthermore, in order to facilitate the cooperation between 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 member 32 is rotatably mounted on the first support plate 312, and the second locking member 33 is rotatably mounted on the second support plate 313. Please refer to Figure 3-Figure 5 The first locking member 32 and the second locking member 33 are cross-arranged at the opening 3211 so as to overlap the first locking member 32 and the second locking member 33 to reduce the volume of the switch lock 30 .

[0069] Furthermore, to facilitate securing the switch lock 30 to the hollow box, the base 31 further includes a securing portion 314 disposed at the upper end of the first support plate 312. Preferably, the securing portion 314 defines a second securing hole 3141 through which the securing portion 314 can be secured to the central control box 20. In one embodiment, the securing portion 314 is secured to the central control box 20 by screws threaded through the second securing holes 3141.

[0070] To allow the first locking member 32 to be rotatably mounted on the first support plate 312, the switch lock 30 further includes a first connecting member 34. A first through-hole 3221 is defined in the rotating portion 322 along the thickness direction, and two first connecting holes 3121 are defined in the first support plate 312. Specifically, the first connecting member 34 is inserted into the first through-hole 3221, and the two first connecting members 34 extend into the two first connecting holes 3121, respectively, thereby enabling the first locking member 32 to rotate about the first connecting member 34.

[0071] In one embodiment, the first connecting member 34 includes but is not limited to a connecting shaft.

[0072] Furthermore, to prevent the first locking member 32 and the second locking member 33 from loosening when locked, the switch lock 30 further includes a first torsion spring 35. Two first fixing holes 3122 are formed in opposite directions on the base 31. Specifically, the first torsion spring 35 is sleeved on the first connecting member 34, with one end of the first torsion spring 35 extending into the first fixing hole 3122 and the other end of the torsion spring abutting the rotating portion 322. Therefore, when the first surface 3241 of the clamping portion 324 abuts the third surface 331 of the second locking member 33, the first torsion spring 35 pushes the rotating portion 322 and causes the first surface 3241 to tightly abut the third surface 331, thereby ensuring the connection 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.

[0073] Furthermore, to allow the second locking member 33 to be rotatably mounted on the second support plate 313, the switch lock 30 also includes a second connecting member 36. The second locking member 33 has a second through-hole 333 defined along its thickness, and the second support plate 313 has two second connecting holes 3131 disposed opposite each other. Specifically, the second connecting member 36 is inserted into the second through-hole 333, with both ends of the second connecting member 36 extending into the two second connecting holes 3131, respectively. This allows the second locking member 33 to rotate about the second connecting member 36, thereby tightening or loosening the first locking member 32 and the second locking member 33.

[0074] In one embodiment, the second connecting member 36 includes but is not limited to a connecting shaft.

[0075] Furthermore, to better prevent the first locking member 32 and the second locking member 33 from loosening when locked, the switch lock 30 further includes a second torsion spring 37. Specifically, the second torsion spring 37 is sleeved on the second connecting member 36, with one end of the second torsion spring 37 abutting the bottom plate 311 and the other end of the second torsion spring 37 abutting the second locking member 33. When the first and second locking members 32 and 33 are locked, the second torsion spring 37 applies a force toward the first locking member 32. Combined with the force applied by the first torsion spring 35 toward the second locking member 33, the first torsion spring 35 and the second torsion spring 37 clamp the first and second locking members 32 and 33 together, preventing the first and second locking members 32 and 33 from separating due to external forces or shaking, thereby enhancing the stability of the connection between the first and second locking members 32 and 33.

[0076] The specific operation process of one embodiment of the present application is as follows: When assembling or detaching the central control box 20 from the bracket 10 of the LED module 100 provided above, first, the lower end of the central control box 20 is abutted against the lower end of the bracket 10, and the central control box 20 is rotated along the abutment point. When the central control box 20 drives one end of the switch lock 30 to contact the bracket 10, the pushing portion 321 is pressed downward in the vertical direction so that the clamping portion 324 passes over the second locking member 33. At this time, the pushing portion 321 is released, and the pushing portion 321 bounces upward under the drive of the first torsion spring 35. The second torsion spring 37 applies a force to the second locking member 33 in the direction of the first locking member 32. 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 together, so that the first surface 3241 is tightly attached to the third surface 331. During this process, the locking portion 323 rotates along the rotating portion 322 with the pushing portion 321 until the locking portion 323 moves toward the opening and closing portion on the bracket 10 and is clamped in the opening and closing opening, thereby fixing the central control box 20 and the bracket 10.

[0077] When the central control box 20 needs to be removed from the bracket 10, the second locking member 33 is pressed to make the second locking member 33 pass over the clamping portion 324, and the first torsion spring 35 and the second torsion spring 37 drive the first locking member 32 and the second locking member 33 to separate. At this time, the locking portion 323 disengages from the opening and closing mouth on the bracket 10, thereby realizing the separation of the central control box 20 from the bracket 10.

[0078] The above method can achieve the fixation or separation of the central control box 20 and the bracket 10 in one step only by pressing the pushing part 321 or the second locking part 33, and due to the pushing force of the first torsion spring 35 and the second torsion spring 37, the first locking part 32 and the second locking part 33 are firmly locked and will not be easily detached due to external force, thereby ensuring the stability of the connection between the central control box 20 and the bracket 10, and avoiding the problem of the central control box 20 and the bracket 10 becoming loose and falling due to the single spring connection and the spring becoming weak after long-term use.

[0079] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
