[0016] In actual design, usually, the compartment separated in box frame 10 is regularly matrix distribution, and each compartment is rectangular. LED lamp beads are installed on the lamp panel, and the lamp panel belongs to the existing component in the field, so its specific structure and installation mode are not described here.

[0017] Usually, two positioning pin shafts 20 are symmetrically installed on the top surface of upper frame 11, and correspondingly, two positioning shaft sleeves 30 are installed on the top surface of lower frame 12, of course, the installation number and position of positioning pin shaft 20 and positioning shaft sleeve 30 are not limited. In addition, one side spring 40 can be installed on each side frame 13, of course, multiple side springs can be installed and the installation position is not limited.

[0018] As Figure 2 And Figure 3 Positioning shaft sleeve 30 includes cylindrical shaft sleeve shell 32, the top of shaft sleeve shell 32 is closed, and the bottom is open, the fixed edge 31 extends outward from the bottom of shaft sleeve shell 32, the fixed hole 310 for installing screw 60 is opened on the fixed edge 31, the guide ring 35 is fixed in the open bottom of shaft sleeve shell 32, the buffer spring 33 that can be elastically deformed (compression and expansion) is arranged in shaft sleeve shell 32, the gasket 34 is connected to the lower end of buffer spring 33, buffer spring 33 and gasket 34 are arranged between the top inner wall of shaft sleeve shell 32 and guide ring 35, and the gasket 34 is between buffer spring 33 and guide ring 35, wherein, the end of buffer spring 33 abutting the top inner wall of shaft sleeve shell 32 can be fixed or not fixed with the top inner wall of shaft sleeve shell 32, and the gasket 34 and guide ring 35 are not fixed.

[0019] In the utility model, the guide ring 35 is used for the positioning pin shaft 20 to be able to quickly align the positioning shaft sleeve 30 to extend into, the gasket 34 is used for compressing the buffer spring 33 and plays the shock absorbing effect. When external force acts, the gasket 34 is extruded under the action of external force and abuts against the buffer spring 33 to compress, when the external force is released, the buffer spring 33 stretches and restores, under the action of no external force, the buffer spring 33 and the gasket 34 abut against the top inner wall of the shaft sleeve shell 32 and the guide ring 35 respectively. The elastic degree of the buffer spring 33 can be reasonably designed according to the size, weight and other factors of the LED box 50, so that it is matched with the LED box, the buffer spring 33 can be compressed in place to obtain better buffering effect, and the purpose of preventing collision is achieved.

[0020] In actual installation, the positioning shaft sleeve 30 is fixed on the lower frame 12 through the screw 60, and the positioning pin shaft 20 can be fixed on the upper frame 11 in the embedded mode, and of course the above-mentioned fixing mode is not limited.

[0021] In actual design, the hole diameter of the positioning hole 120, the opening diameter of the guide ring 35 and the outer diameter of the positioning pin shaft 20 are matched, so that the positioning pin shaft 20 can smoothly pass through the positioning hole 120 and the guide ring 35 and extend into the inside of the shaft sleeve shell 32.

[0022] As shown in Figure 1 , the side elastic sheet 40 comprises a V-shaped sheet body 41, and the two sides of the V-shaped sheet body 41 extend with fixing sheets 42, wherein: the opening 15 is formed in the side frame 13, and the V-shaped sheet body 41 extends out of the side frame 13 from the opening 15, and the two fixing sheets 42 are fixed with the inner wall of the side frame 13 through screws.

[0023] In actual design, for the two horizontally adjacent utility model LED movie screen anti-collision LED boxes 50, the side elastic sheets 40 on the opposite two side frames 13 are preferably arranged in up-down staggered mode, as shown in Figure 5 .

[0024] When external force acts, the V-shaped sheet body 41 is extruded and deformed under the action of external force and shrinks into the opening 15 of the side frame 13, and when the external force is released, the V-shaped sheet body 41 restores and again extends out of the side frame 13 from the opening 15 and is exposed outside the box frame 10.

[0025] As shown in Figure 6 , the positioning pin shaft 20 is provided with a lifting hole 201 for convenient lifting.

[0026] In addition, the upper frame 11 and the lower frame 12 of the box frame 10 are provided with fastening holes (not shown in the figure), and the fastening holes of the upper utility model LED movie screen anti-collision LED box 50 are arranged in up-down opposite mode with the fastening holes of the lower utility model LED movie screen anti-collision LED box 50.

[0027] Reference will be made to Figures 4 to 7To illustrate the installation process of the LED module (the lamp panel is not shown in the figure).

[0028] During installation, the LED module of the lowermost layer (including the LED box 50 of the utility model and the lamp panel installed thereon) is installed first. For two LED modules adjacent to each other in the horizontal direction, the LED module to be installed first contacts the corresponding side frame 13 of the adjacent LED module through the side spring 40 on the side frame 13, and then the side frames 13 of the two LED modules abut against each other, thereby effectively avoiding direct collision between the two. Then, through the lifting cable, the LED module to be installed is lifted to the already installed LED module below by means of the lifting hole 201 on the positioning pin shaft 20. At this time, the two LED modules are roughly aligned, that is, the positioning shaft sleeve 30 of the upper LED module is roughly opposite the positioning pin shaft 20 of the lower LED module. In other words, when the positioning pin shaft 20 is roughly aligned with the guide ring 35 of the positioning shaft sleeve 30, the lifting cable is loosened. At this time, the positioning shaft sleeve 30 on the upper LED module slowly sleeves down on the positioning pin shaft 20 on the lower LED module due to the weight of the upper LED module itself, that is, the positioning pin shaft 20 penetrates the guide ring 35 and enters the shaft sleeve shell 32, specifically, the positioning pin shaft 20 abuts against the gasket 34 and compresses the buffer spring 33, until the lower frame 12 of the upper LED module abuts against and presses against the upper frame 11 of the lower LED module, at which time the buffer spring 33 is compressed in place. Thus, the box frame 10 of the two LED modules can be fastened by the bolt assembly (bolt and matching nut), that is, the bolt penetrates the fastening hole of the upper and lower box frames 10, and the nut is matched to complete the fixation between the upper and lower box frames 10.

[0029] At the same time, when installing in the horizontal direction, for example, from left to right, the LED module to be installed first contacts the corresponding side frame 13 of the adjacent LED module through the side spring 40 on the side frame 13, and the side spring 40 is compressed until the side frames 13 of the two LED modules abut against each other, thereby effectively avoiding direct collision between the two LED boxes 50.

[0030] From the above installation process, it can be seen that the utility model uses a buffer spring 33 in the vertical direction to achieve the purpose of shock absorption and prevent collision, and uses a positioning pin shaft 20 to align the shaft sleeve shell 32 to achieve the purpose of position alignment. Similarly, in the horizontal direction, the side spring 40 is used to achieve the purpose of shock absorption and prevent collision, so as to prevent the LED box itself or the lamp panel thereon from being damaged due to collision during the stacking and installation of the LED module.

[0031] The above is the preferred embodiment of the present application and the technical principle used, for those skilled in the art, without departing from the spirit and scope of the present application, any equivalent transformation, simple replacement, etc. based on the technical scheme of the present application, obvious changes, all belong to the protection scope of the present application.
