The first support column 11 is provided with a first mounting hole 111, and the first mounting hole 111 extends from the upper end surface 11a of the first support column 11 along the axis (in the opposite direction to the Z direction) of the first support column 11.

In order to prevent the falling of lamp panel module 20, the mounting structure of the LED display screen of this embodiment includes first limiting portion 40, first limiting portion 40 is disposed on box 10, first limiting portion 40 includes first limiting pin 41, first limiting pin 41 is disposed as: slidably inserted onto lamp panel module 20 and retractable from slidably ground lamp panel module 20, after first limiting pin 41 is inserted into first accommodating portion 21 provided on lamp panel module 20, the removal of lamp panel module 20 is limited, that is, the movement of lamp panel module 20 in the Z direction is limited. An angle between a direction in which the first limiting pin 41 is inserted into the first accommodating portion 21 and a direction in which the lamp panel module 20 is mounted to the housing 10 (a direction opposite to the Z direction) is preferably 90 degrees or less, and more preferably, a direction in which the first limiting pin 41 is inserted into the lamp panel module 20 is perpendicular to a direction in which the lamp panel module 20 is mounted to the housing 10 (a direction opposite to the Z direction), and herein, a direction in which the first limiting pin 41 is inserted into the first accommodating portion 21 in the direction perpendicular to the Z direction is referred to as a Y direction. By inserting the first restriction pin 41 into the first accommodation portion 21 in the Y direction, it is possible to facilitate the release of the restriction of the globe module 20 by the first restriction pin 41 by the release portion 50, which will be described later, while ensuring that the first restriction portion 40 restricts the removal of the globe module 20 in the reverse direction in the Z direction. Of course, in practice, the angle between the direction in which the first limiting pin 41 is inserted into the lamp panel module 20 and the direction in which the lamp panel module 20 is mounted on the housing 10 may be larger than 90 degrees and smaller than 180 degrees, but in this case, it is necessary to provide another limiting member for limiting the movement of the lamp panel module 20 in the Y direction.

In order to facilitate the detachment and maintenance of the lamp panel module 20, a first communicating portion that can be communicated to the first limiting pin 41 is provided on the front surface of the LED display screen, the first communicating portion may include a first through hole 23, and the first limiting pin 41 may be driven to retract at the first through hole 23 (a position where the first limiting pin 41 is communicated with the first through hole 23). The first limiting pin 41 can be driven to retract by the releasing portion 50, the releasing portion 50 can penetrate through the lamp panel module 20 from the front face 20a of the LED display screen and abut against the first limiting portion 40, and the first limiting portion 40 can be retracted from the lamp panel module 20. Here, the front surface 20a of the LED display panel (refer to fig. 3a for assistance) refers to a display surface on which the LED display panel is exposed to the outside and on which various videos and the like are played, and the panel module 20 can be easily detached by providing a release portion 50 for releasing the first restriction portion 40 on the front surface of the LED display panel.

Fig. 5(a) is a partial schematic view of a structure for mounting an LED display panel capable of preventing falling, fig. 5(b) is a schematic view of a first limiting pin 41, fig. 5(c) is a schematic view of a mounting cover 13, and a structure for mounting an LED display panel capable of preventing falling, in which the lamp panel module 20 is prevented from falling by the first limiting portion 40, will be described in detail below with reference to fig. 5(a), fig. 5(b), and fig. 5(c) and with continued reference to fig. 4.

As described above, the first limiting portion 40 includes the first limiting pin 41, the first accommodating portion 21 is provided on the lamp panel module 20, and the first limiting pin 41 is slidably inserted into the first accommodating portion 21 or slidably retracted from the first accommodating portion 21. The first restricting pin 41 may be slidably mounted to the housing 10 in any known manner. After the lamp panel module 20 is mounted to the housing 10, the first receiving portion 21 and the first restricting pin 41 face each other in the Y direction. In an alternative embodiment, the case 10 is provided with a first guide portion 113, and the first restricting pin 41 is at least partially disposed in the first guide portion 113 and slidable in the first guide portion 113. Specifically, the first guide portion 113 may be a first guide hole provided through the side wall 11b of the first support column 11, that is, the first guide hole as the first guide portion 113 communicates with the first mounting hole 111, the tip portion of the first restricting pin 41 is slidably mounted on the side wall 11b of the first support column 11 in the radial direction (Y direction) of the first support column 11, the first accommodating portion 21 is provided on the first mounting protrusion 22 of the globe module 20, and when the first mounting protrusion 22 is inserted into the first mounting hole 111, the first limiting pin 41 can be pressed to slide towards the radial outside (i.e. the reverse direction of the Y direction) of the first supporting column 11, so that the lamp panel module 20 can be installed on the housing 10, after the lamp panel module 20 is installed to the housing 10, the first accommodating portion 21 is accommodated in the first installation hole 111 and communicated with the first guide portion 113, and the first accommodating portion 21 is opposite to the first limiting pin 41 in the Y direction. At this time, the first restriction pin 41 is inserted into the first accommodation portion 21 so as to be slidable radially inward (Y direction) of the first support column 11, and restricts the detachment of the first mounting protrusion 22 from the first mounting hole 111, that is, movement of the first mounting protrusion 22 in the Z direction, thereby restricting the removal of the globe module 20.

As described above, when the first mounting convex portion 22 is inserted into the first mounting hole 111, the first limiting pin 41 can be pressed to slide outward in the radial direction of the first support column 11, that is, the first mounting convex portion 22 can drive the first limiting pin 41 to slide. In an alternative embodiment, the first limiting pin 41 includes a first segment 411 inserted into the first receiving portion 21, the first segment 411 is located at the front end of the first limiting pin 41, the first segment 411 is provided with a first guiding surface 411a having a hemispherical shape, an arc shape or an inclined plane shape, in an initial state, the first segment 411 passes through the first guiding portion 113 and is exposed in the first mounting hole 111, when the first mounting protrusion 22 is inserted into the first mounting hole 111, the first mounting protrusion 22 first abuts against the first guiding surface 411a of the first segment 411 and slides along the first guiding surface 411a, at the same time, the first mounting protrusion 22 presses the first segment 411 to retract the first limiting pin 41 integrally toward the first guiding portion 113, when the first receiving portion 21 is opposite to the first guiding portion 113, because the first mounting protrusion 22 does not press the first segment 411 any more, the first limiting pin 41 protrudes from the first guiding portion 113 again, and inserted into the first receiving portion 21. The shape of the first accommodating portion 21 is a concave shape matching the shape of the first section 411, for example, when the first section 411 is hemispherical, the first accommodating portion 21 is also hemispherical; when the first segment 411 is arc-shaped or inclined, the first accommodating portion 21 is also arc-shaped or inclined concave.

In the present embodiment, the first restricting pin 41 is retracted by the pressing of the first mounting projection 22. For the protrusion of the first mounting projection 22 from the first guide portion 113, for example, the first restriction pin 41 may be protruded from the first guide portion 113 by providing a spring mechanism. In an alternative embodiment, the first limiting portion 40 further includes a second spring 42, and the second spring 42 drives the first limiting pin 41 to be slidably inserted into the first receiving portion 21. The second spring 42 is fitted around the first restricting pin 41, and one end of the second spring 42 abuts against the first restricting pin 41 and the other end abuts against the case 10. In the mounted state, the second spring 42 can push the first restricting pin 41 and expose the first segment 411 in the first mounting hole 111, and thus, although the first restricting pin 41 can be retracted by the pressing of the first mounting protrusion 22, the first restricting pin 41 can be automatically extended and inserted into the first housing portion 21 by the second spring 42 when the position of the first housing portion 21 is opposite to the position of the first guide portion 113. Here, when the lamp panel module 20 is mounted to the housing 10, the mounting stroke of the lamp panel module 20 is generally long for the first limiting portion 41, and in this process, the first limiting pin 41 can be easily retracted by the weight of the lamp panel module 20 and the power potential energy generated when the lamp panel module 20 is mounted, so that the lamp panel module 20 can be conveniently mounted, and in the mounted state, since the first segment 411 of the first limiting pin 41 is already inserted into the first accommodating portion 21 of the first mounting convex portion 22, the movable stroke of the lamp panel module 2 is very short for the first limiting portion 40, so that it is difficult to retract the first limiting pin 41, and therefore, the first limiting portion 40 has a very obvious effect of preventing the lamp panel module 20 from falling, and thus, the lamp panel module 20 can be prevented from falling accidentally. Further, when the output force of the second spring 42 is adjusted (for example, the wire diameter of the second spring 42 is increased), the force with which the first restriction pin 41 is inserted into the first housing portion 21 can be further increased.

In order to firmly support the first restricting pin 41, the case 10 may be provided with a second supporting column 12 beside the first supporting column 11, the second supporting column 12 may be provided with a second guide hole 121 coaxial with the first guide hole as the first guide portion 113, a front end portion (including the first step portion 411) of the first restricting pin 41 may slide in the first guide portion 113, and a rear end portion of the first restricting pin 41 may slide in the second guide hole 121. In addition, in order to facilitate the detachment of the first limiting pin 41, a mounting cover plate 13 for mounting the first limiting pin 41 may be further included, and the mounting cover plate 13 is mounted to the second supporting column 12 and extends to the first supporting column 11. The front end of the mounting cover 13 is provided with a semicircular first opening 131, a semicircular second opening 113a with the same radius as that of the first opening 131 is formed on the side wall 11b of the upper end surface 11a of the first support column 11, when the mounting cover 13 is mounted on the second support column 12, the first opening 131 and the second opening 113a together form a first guide hole with a closed cross section, and the second guide hole 121 can also be formed in the same way. Therefore, after the mounting cover plate 13 is removed, the first limiting pin 41 can be easily detached from the first support column 11 and the second support column 12, and the removal is very convenient.

The following describes in detail a configuration in which the first restriction unit 40 releases the restriction of the light panel module 20 by the release unit 50.

The front surface of the lamp panel module 20 is provided with the first through hole 23 (refer to fig. 3(a) for assistance), and the positions of the first through hole 23 and the first limiting portion 40 may be designed in advance, and as long as the first through hole 23 can not penetrate through some PCBs and LED light emitting units of the lamp panel 201, the first through hole 23 and the first limiting portion 40 may be disposed at any position of the LED display screen. The first through hole 23 communicates with the first limiting portion 40, the releasing portion 50 includes a rod-shaped first driving member 51, the first driving member 51 can abut against the first limiting pin 41 through the first through hole 23, and the releasing portion 50 retracts the first limiting pin 41 from the first accommodating portion 21 by the first driving member 51, so that the limitation of the first limiting portion 40 on the lamp panel module 20 is released. Through set up first through-hole 23 on lamp plate module 20, the front 20a of the portion of being convenient for remove 50 from the LED display screen removes the restriction of first restriction portion 40 to lamp plate module 20, and it is very convenient to dismantle. In an alternative embodiment, the first restricting pin 41 is provided with a first inclined portion 412, and the first driving member 51 abuts the first inclined portion 412 via the first through hole 23 and is slidable on the first inclined portion 412, thereby pressing the first inclined portion 412 and retracting the first restricting pin 41. After first restriction portion 40 retracts, lamp panel module 20 can be disassembled. Here, the releasing portion 50 is a member detachable from the lamp panel module 20, such as a screw driver, and does not need to be left on the lamp panel module 20, and it is only necessary to abut the releasing portion 50 against the first limiting portion 40 through the first through hole 23 and release the releasing portion at the time of detachment.

Fig. 6(a) is a schematic view of another embodiment of the mounting structure of the anti-fall LED display panel, fig. 6(b) is a schematic view of the first restricting pin in the embodiment of fig. 6(a), and the first restricting portion 60 of the other embodiment will be described below with reference to fig. 6(a) and 6 (b). The first step portion 611 of the first limiting pin 61 of the first limiting portion 60 may be provided with a first guide surface 611a only on the side opposite to the mounting direction (the direction opposite to the Z direction) of the bezel module 20, and may be provided with a first locking surface 611b cut out parallel to the axial direction of the first limiting pin 61 on the side opposite to the removal direction (the Z direction) of the bezel module 20. On the other hand, the first housing portion 21a is also provided as a recess matching the shape of the first step portion 611, i.e., the upper surface is formed in a hemispherical shape, an arc shape, or a slope shape, and the lower surface is formed in a flat surface capable of being fitted to the first locking surface 611 b. In this embodiment, the first restriction pin 61 of the first restriction portion 60 and the lower surface of the first accommodation portion 21a of the lamp panel module 20 are attached to each other in a planar manner, and the first restriction pin 61 cannot be pressed to be retracted when detached, so that the first restriction portion 60 prevents the restriction effect of the lamp panel module 20, which is more significant. In this embodiment, in order to prevent the first limiting pin 61 from rotating, the bottom surface of the second hole 113b provided in the first support column 11 may be a flat surface, and the first latching surface 611b may slide on the bottom surface of the second hole 113 b. At this time, the first guide portion 113 is actually a chamfered hole, and therefore, the first restricting pin 61 can be prevented from rotating.

In this embodiment, the first restricting pin 71 of the first restricting portion 70 is provided with a stepped portion 711, whereas a gap exists between the first through hole 23 and the first driving member 51, for example, the first through hole 23 is a U-shaped hole. The first driver 51 passes through the first through hole 23 of the U-shaped hole, the first driver 51 abuts against the first limiting pin 71, and when the first driver 51 is pushed in the direction in which the first limiting pin 71 retracts, the radial outer side of the first driver 51 abuts against the side 711a of the stepped portion 711, and the first limiting pin 71 is pushed to compress the second spring 42, and retract from the first accommodating portion 21 into the first guide portion 113. After the first restriction portion 70 is retracted, the lamp set module 20 can be easily detached from the housing 10.

In this embodiment, the first restricting pin 81 of the first restricting portion 80 is provided with an annular groove portion 811, whereas a gap exists between the first through hole 23 and the first driving member 51, for example, the first through hole 23 is a U-shaped hole. The first driver 51 passes through the first through hole 23 of the U-shaped hole, and the first driver 51 abuts inside the annular groove portion 811 of the first restricting pin 81. In this embodiment, the first driving member 51 may push the first restricting pin 81 to extend or retract. In this embodiment, a spring may not be provided, and the first limiting pin 81 may be provided with a locking convex portion 812 for locking the first limiting pin 81, and correspondingly, a locking groove 114 may be provided in the first guide portion 113, and when the first limiting pin 81 is inserted into the first accommodating portion 21, the locking convex portion 812 is locked in the locking groove 114, so that the first limiting pin 81 can be prevented from sliding in the first guide portion 113.
