Description

Technical Field

[0001] The invention relates to the technical field of LED display screens, and in particular to an anti-falling structure of an LED display screen. Background Art

[0002] When installing an LED display, you should consider its safety, reliability and ease of maintenance.

[0003] There are two main ways to install LED display screen modules. The first is to install and fix the light board module of the LED display screen by screws. Nut columns are provided on the bottom shell, and through holes are provided on the box body to allow screws to pass through. The light board module is fixed from the back of the box body by screws. Although this method can firmly install the light board module to prevent it from falling, disassembly and maintenance can only be carried out at the back of the box body. In the case of no maintenance channel (for example, directly installed on the wall), it is difficult to maintain.

[0004] The second method is to install the LED display panel module by magnets. Magnets are good for assembly, disassembly and maintenance of the panel module, but the magnets may weaken in high temperature environments (such as outdoors in summer) and fail to attract the panel module, which may cause the panel module to fall. In addition, in strong winds (such as typhoons), insufficient magnet attraction may also cause the panel module to fall. Summary of the invention

[0005] In view of the above technical problems, the present invention proposes an anti-falling structure for an LED display screen in order to prevent the light board module from falling and facilitate the maintenance of the LED display screen.

[0007] Preferably, a first clamping member is provided at an upper end portion of the first limiting member, a second clamping member is provided on the light board module, and the first clamping member is rotatably clamped onto the second clamping member.

[0008] Further preferably, a first guide surface is provided at the upper end portion of the first limiting member, and the first guide surface is located above the first clamping member. When the light board module is installed to the box body, the second clamping member slides on the first guide surface and pushes the first limiting member to rotate in a direction of disengaging from the light board module.

[0009] Preferably, a second guide surface is provided at an upper end portion of the first limiting member, and the second guide surface is opposite to the first communicating portion.

[0010] Further preferably, it also includes a release part, which includes a first driving part, and the first connecting part includes a first through hole arranged on the front side of the light board module. The first driving part can abut the first limiting part and slide on the second guide surface through the first through hole, and push the first limiting part to rotate in the direction of disengaging from the light board module.

[0011] More preferably, the first connecting portion further comprises a first threaded hole provided on the lamp board module, the first threaded hole being coaxial with the first through hole; and the first driving member is provided with a first threaded portion, the first threaded portion being engaged with the first threaded hole.

[0012] Preferably, the first limiting portion further comprises a mounting seat mounted to the box body, and the first limiting member is rotatably mounted on the mounting seat.

[0013] Further preferably, the first limiting portion further includes an elastic member, one end of the elastic member abuts against the first limiting member to push the first limiting member to be clamped onto the light board module.

[0016] The anti-falling structure of the LED display screen of the present invention is provided with a first limiting member that can be rotatably engaged with the light board module, so that the disassembly of the light board module relative to the box body is limited, thereby preventing the light board module from falling. In addition, since the front of the LED display screen is provided with a first connecting portion connected to the first limiting member, the first limiting member can be driven to rotate and disengage from the light board module at the position connected to the first connecting portion, thereby facilitating the disassembly of the light board module and facilitating the maintenance of the LED display screen.

Figures 1 to 3 , the installation structure of the LED display screen includes a box body 10 and a light board module 20, and the light board module 20 is installed on the box body 10. The light board module 20 includes a light board 201 and a bottom shell 202, and the light board 201 includes a PCB board (not shown) and an LED light-emitting unit (not shown) arranged in an array on the PCB board, and the light board 201 can be installed on the bottom shell 202 by screws. In order to facilitate the installation of the light board module 20 on the box body 10, in an optional embodiment, a first support column 11 is provided on the box body 10, and the first support column 11 is formed to protrude in a direction perpendicular to the bottom surface 101 of the box body 10. Here, the direction perpendicular to the bottom surface 101 of the box body 10 is set as the Z direction, and the Z direction is the normal direction perpendicular to the bottom surface 101 of the box body 10. A first mounting hole 111 is opened on the first support column 11, and the first mounting hole 111 starts from the upper end surface 11a of the first support column 11 and extends along the axis of the first support column 11 (the opposite direction of the Z direction). Correspondingly, the light board module 20 is provided with a first mounting protrusion 22. Specifically, the first mounting protrusion 22 is provided on the bottom shell 202. The first mounting protrusion 22 is columnar. The diameter of the first mounting protrusion 22 is slightly smaller than the aperture of the first mounting hole 111. For example, the diameter of the first mounting protrusion 22 is 1 mm to 3 mm smaller than the aperture of the first mounting hole 111. When the light board module 20 is installed in the box 10, the first mounting protrusion 22 is inserted into the first mounting hole 111, thereby facilitating the alignment of the positions of the light board module 20 and the box 10. In addition, the box 10 can be provided with a plurality of first support columns 11, each of which is provided with a first mounting hole 111. Correspondingly, the light board module 20 can also be provided with a plurality of first mounting protrusions 22.

[0027] Figure 4 yes Figure 1 The main view of the anti-fall structure of the LED display. Figure 5 is a schematic diagram of the installation state of the first limiting portion 40, Figure 6Schematic diagrams of the first limiting portion 40, wherein (a) is a schematic diagram of the entire first limiting portion 40, (b) is a schematic diagram of the first limiting member 41, and (c) is a schematic diagram of the elastic member 43. Figures 4 to 6 In order to prevent the light board module 20 from falling, the installation structure of the LED display screen of the present embodiment further includes a first limiting portion 40, which is arranged on the housing 10. The first limiting portion 40 includes a first limiting member 41, which can be directly rotatably mounted on the housing 10 or rotatably mounted on the housing 10 through other components. The first limiting member 41 can be rotatably clamped on the light board module 20 or rotatably disengaged from the light board module 20. After the first limiting member 41 is clamped on the light board module 20, the disassembly of the light board module 20 relative to the housing 10 is restricted. By providing the first limiting member 41 that is rotatably clamped on the light board module 20, the disassembly of the light board module 20 relative to the housing 10 is restricted, thereby preventing the light board module 20 from falling.

[0028] In an optional embodiment, the first limiting portion 40 includes a mounting seat 42, and the mounting seat 42 has a mounting flange 421. An upper cylinder 422 is provided on the mounting flange 421, and a lower cylinder 423 is provided below the mounting flange 421. The mounting seat 42 is mounted on the box body 10 through the mounting flange 421, and the upper cylinder 422 is accommodated in the box body 10. A pin 44 is mounted on the wall of the lower cylinder 423 below the mounting flange 421. To facilitate the installation of the pin 44, one end of the pin 44 in the length direction has a mounting thread, and the other end of the pin 44 in the length direction has a knurling. The pin 44 is locked to the wall of the lower cylinder 423 by clamping the pin 44 (for example, by using fingers) through the knurling. The first limiting member 41 is provided with a rotation hole 415 for allowing the pin 44 to be inserted at a lower middle position in the length direction thereof. The first limiting member 41 is mounted on the pin 44 through the rotation hole 415 and can rotate around the axis of the pin 44, so that the first limiting member 41 can be rotatably mounted on the mounting seat 42. The first limiting member 41 is provided with a first clamping member 411 at an upper middle position. The first clamping member 411 can be in a shape protruding along the width direction of the first limiting member 41, or can be formed by opening a notch on the first limiting member 41. The clamping surface 411a of the first clamping member 411 is set to be substantially perpendicular to the length direction of the first limiting member 41. Here, the middle of the length direction of the first limiting member 41 is not limited to the middle part, but the area between the upper end 41a and the lower end 41b of the first limiting member 41 in the length direction can be considered as the middle part, and the side close to the lower end 41b is considered as the middle lower position, and the side close to the upper end 41a is considered as the middle upper position.

[0029] Corresponding to the first clamping member 411 provided on the first limiting member 41, the light board module 20 is provided with a second clamping member 203, and the second clamping member 203 is configured to be rotatably clamped by the first clamping member 411. Specifically, the second clamping member 203 can be directly provided on the bottom shell 202 of the light board module 20, or can be installed on the bottom shell 202 of the light board module 20 as an independent component. For example, the second clamping member 203 can be a sheet metal member in a U shape, one end 203a of the second clamping member 203 is installed on the bottom shell 202, and the other end 203b of the second clamping member 203 is a cantilever end. When the first limiting member 41 rotates, for example, in the present embodiment, it rotates clockwise, the holding surface 411a of the first clamping member 411 is clamped to the inner side of the cantilever end 203b of the second clamping member 203, and the holding surface 411a of the first clamping member 411 is substantially parallel to the inner side of the cantilever end 203b of the second clamping member 203, thereby limiting the disassembly of the light board module 20 relative to the box body 10. When the first limiting member 41 rotates in the opposite direction, for example, in the present embodiment, it rotates counterclockwise, the holding surface 411a of the first clamping member 411 is disengaged from the inner side of the cantilever end 203b of the second clamping member 203, thereby allowing the light board module 20 to be freely disassembled relative to the box body 10.

[0030] Further preferably, the first limiting part 40 further includes an elastic member 43, one end of which abuts against the first limiting member 41, pushing the first limiting member 41 to be clamped on the light board module 20. Specifically, the elastic member 43 pushes the first clamping member 411 of the first limiting member 41 to be clamped on the second clamping member 203 of the light board module 20. For example, the elastic member 43 can be a torsion spring member 43, and both sides of the thickness of the first limiting member 41 are respectively provided with mounting shafts 416 protruding coaxially with the rotation hole 415 of the first limiting member 41, and the torsion spring member 43 is inserted into the mounting shaft 416. The torsion spring member 43 includes a first arm portion 431 and a second arm portion 432, and the first arm portion 431 abuts against the first limiting member 41. The first arm portion 431 of the torsion spring member applies force in the direction of clamping the first clamping member 411 to the second clamping member 203 of the light board module 20, so that the first limiting member 41 remains clamped on the light board module 20 in the absence of external force. The second arm 432 is clamped on the mounting seat 42 or the light board module 20. For example, a notch 424 is provided on the lower cylinder 423 of the mounting seat 42, and the second arm 432 of the torsion spring is clamped on the outside of the notch 424. In addition, the wire diameter of the torsion spring can be adjusted as needed to adjust the clamping force of the first limiting member 41 clamping the light board module 20.

[0031] The elastic member 43 may also be selected as a coil spring, a helical spring, etc. When a coil spring (not shown) is selected, the coil spring may be accommodated in the rotation hole 415 of the first limiting member 41, with one end fixed to the pin 44 and the other end fixed to the first limiting member 41. When a helical spring is selected, the helical spring (not shown) may be mounted on the mounting seat 42 at one end and abutted against the middle upper portion of the first limiting member 41 at the other end. Of course, the elastic member 43 is only a preferred embodiment for resetting the first limiting member 41, and those skilled in the art may select any other known resetting mechanism to reset the first limiting member 41 from a state of being disengaged relative to the light board module 20 to a state of being stuck relative to the light board module 20.

[0032] In order to facilitate the installation of the light board module 20 on the box body 10, preferably, a first guide surface 412 is opened on the upper end portion 41a of the first limiting member 41, and the first guide surface 412 is in the shape of an inclined surface or an arc surface that is gradually inclined in the opposite direction of the Z direction and toward the outer side of the first limiting member 41. The first guide surface 412 is located above the first clamping member 411. When the light board module 20 is installed on the box body 10, the second clamping member 203 slides on the first guide surface 412. Since the light board module 20 is installed on the box body 10 in the opposite direction of the Z direction, when the light board module 20 is installed on the box body 10, the first limiting member 41 is pushed to rotate in the direction of disengagement of the light board module 20 (counterclockwise rotation in this embodiment). When the second clamping member 203 reaches the bottom of the first clamping member 411, the first limiting member 41 is reset by the force of the elastic member 43 (clockwise rotation in this embodiment) and is clamped to the inner side of the second clamping member 203. Therefore, the light board module 20 can be easily installed on the box body 10 without the aid of tools.

[0033] In order to facilitate the disassembly of the light board module 20 and maintain the LED display screen, a first connecting portion 30 may be further included. The first connecting portion 30 is arranged on the front of the LED display screen and can be connected to the first limiting member 41 in the opposite direction of the Z direction. The first limiting member 41 can be driven to rotate at the position connected to the first connecting portion 30 and disengaged from the light board module 20. Here, the front of the LED display screen refers to the display surface of the LED display screen. The first connecting portion 30 may include a first through hole 301 arranged on the front of the light board module 20. The first limiting member 41 can be driven to rotate at the first through hole 301 and disengaged from the light board module 20. For example, the upper end portion 41a of the first limiting member 41 is provided with a second guide surface 413. The second guide surface 413 is opposite to the first connecting portion 30. Similar to the first guide surface 412, the second guide surface 413 is also in the shape of an inclined surface or an arc surface that is gradually inclined in the opposite direction of the Z direction and toward the outside of the first limiting member 41. In addition, a release part 50 is also included, and the release part 50 includes a first driving member 51. The first driving member 51 is in the shape of an elongated column, and can abut against the first limiting member 41 through the first through hole 301 and slide on the second guide surface 413. Since the first driving member 51 abuts against the first limiting member 41 in the reverse direction of the Z direction, it can push the first limiting member 41 to rotate and disengage from the light board module 20 (in the counterclockwise direction in this embodiment). It should be noted that the first guide surface 412 and the second guide surface 413 can be the same inclined surface.

[0034] In order to further facilitate the disassembly of the light board module 20, the first connecting portion 30 may also include a first threaded hole 302 provided on the light board module 20. For example, a nut may be fixed on the back side (the side opposite to the box body 10) of the bottom shell 202 of the light board module 20, and the threaded hole of the nut is used as the first threaded hole 302. The first through hole 301 passes through the light board 201 and the bottom shell 202 of the light board module 20, and the first threaded hole 302 is set to be coaxial with the first through hole 301. Correspondingly, a first threaded portion 511 is provided on the first driving member 51. After the first driving member 51 is inserted into the first through hole 301, the first threaded portion 511 is engaged with the first threaded hole 302. By rotating the first driving member 51, the first driving member 51 gradually abuts against the second guide surface 413 of the first limiting member 41, and accurately drives the first limiting member 41 to rotate. In this embodiment, after the first clamping member 411 of the first limiting member 41 is disengaged from the second clamping member 203 of the light board module 20, the first driving member 51 of the release member 50 is still fixed to the light board module 20 through the engagement of the first threaded portion 511 and the first threaded hole 302. Therefore, the light board module 20 can be easily removed by holding the release member 50. In order to facilitate the operator to hold the release member 50, the release member 50 may further include a holding knob 52, which may be any known knob and fixed to the first driving member 51. In addition, the first driving member 51 may also be any known elongated columnar tool, such as a screw pen, etc.

[0035] In order to facilitate the removal of the light board module 20 from the back of the box 10, preferably, a rotating handle 414 is provided at the lower end 41b of the first limiting member 41, and the rotating handle 414 extends to the outside of the back of the box 10, and the rotating handle 414 is integrally formed with the first limiting member 41. Therefore, the operator can conveniently disengage the first limiting member 41 from the light board module 20 by providing the rotating handle 414 on the back of the box 10, and remove the light board module 20.

[0036] In addition, in order to further enhance the anti-falling effect of the installation structure of the LED display screen, a plurality of first magnets 103 are provided on the box body 10, and the first magnets 103 are fixed to the box body 10. The first magnets 103 can be distributed in multiple places as needed. For example, if the box body 10 is square or rectangular, the first magnets 103 are distributed in multiple places at the edges of the box body 10. The bottom shell 202 is provided with components such as iron sheets 203 that can be adsorbed by the first magnets 103. When the light board module 20 is installed on the box body 10, the light board module 20 is adsorbed by the first magnets 103 installed on the box body 10 through the iron sheets 203, so as to be fixed.

[0037] The various specific technical features described in the above specific embodiments can be combined in any way without contradiction. To avoid unnecessary repetition, the present invention does not separately explain various possible combinations.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention but not to limit the same. Any modification or equivalent substitution that does not depart from the scope of the present invention shall be included in the technical solutions of the present invention.
