detailed description

The present invention is further described below in conjunction with accompanying drawing and embodiment:

As shown in Figure 1-2, an LED display screen includes several LED display cabinets 100, and two adjacent LED display cabinets 100 are connected by an installation structure that can adjust the splicing angle of the LED display cabinets 100. The side surface 110 of the display box 100 is inclined, and the rear side of the inclined surface is inclined inwardly.

As shown in Figure 3-10, an installation structure that can adjust the splicing angle of the LED display box is provided with an adjustment component 200 on one side or adjacent two sides of the LED display box 100, on the same side as the adjustment component 200 Or the side 110 of the cabinet on the opposite side is provided with a middle lock assembly 300 , the multi-angle adjustment can be realized through the adjustment assembly 200 , and the fixing of the two LED display cabinets 100 can be realized through the middle lock assembly 300 .

Specifically: the adjustment assembly 200 includes an adjustment wheel 210 and a knob 220 , the knob 220 is fixedly connected to the side of the adjustment wheel 210 , and the knob 220 drives the adjustment wheel 210 to rotate. The adjustment assembly 200 also includes a wrench assembly 230 and a cover plate 250 (shown in FIGS. 3-4 ). The wrench assembly 230 includes a wrench 231 , the inner side of the wrench 231 is set on the knob 220 , the wrench 231 drives the knob 220 to rotate, and the cover plate 250 fixes the adjustment wheel 210 on the side of the LED display box 100 .

As shown in Figure 5-8, there are several adjustment surfaces on the adjustment wheel 210, and the inclination angles of each adjustment surface are different, but the whole is along the axial direction of the adjustment wheel 210, and two adjacent LED display cabinets 100 When connected, the adjustment surface contacts and connects with the box side 110 of another LED display box 100 .

In this embodiment, the adjustment surface includes an inner arc surface 211, a 0-degree angle surface 212, and an outer arc surface 213. The direction is an obtuse angle, and the outer arc surface 213 and the outward direction of the axis of the adjustment wheel 210 form an acute angle, that is, the planes where the three adjustment surfaces are located intersect.

In the adjustment wheel 210, each adjustment surface is provided with a positioning hole 215, and a positioning bead 120 is provided on the box side 110 opposite to the adjustment assembly 200, and the positioning bead 120 is engaged with the positioning hole 215 so that the two When the two LED display cabinets 100 are connected, the positioning is more accurate.

The side of the adjustment wheel 210 is also provided with a limit hole 216, and every time a fixed angle is rotated, the limit hole 216 is locked with the limit bead 130 on the LED display box 100 to realize the positioning of the angle.

As shown in Figure 9, the side of the adjustment wheel 210 is provided with a fixed column, the fixed column is provided with a fixed cut surface, the knob 220 is sleeved on the fixed column, and the knob 220 is stuck with the fixed cut surface, so that the two will not rotate mutually, and then It is ensured that the knob 220 drives the adjustment wheel 210 to rotate more precisely. The screw 240 passes through the knob 220 and is fixedly connected to the adjustment wheel 210, so that the knob 220 is fixedly connected to the adjustment wheel 210, so that the knob 220 will not fall off from the fixing column, and the structure is more secure.

For easy identification, the knob 220 is provided with an indicator mark of the rotation angle.

As shown in Figure 10, the inner side of the wrench 231 is covered with a wrench spring 232, one end of the wrench spring 232 is connected to the wrench 231, and the other end is connected to the buckle 233, and the buckle 233 is set in the slot on the knob 220. In this embodiment The middle knob 220 is provided with 6 card slots. The side of the wrench 231 is fixedly connected to the LED display box 100 through the tension spring 260 (shown in Figure 3-4). So that the extension spring 260 will not be resisted by the buckle 233 when it is pulled back.

The wrench 231 can drive the knob 220 to rotate, and then drive the adjustment wheel 210 to rotate, and at the same time display the return of the wrench 231. The specific principle is: as the arrow in the figure, move the wrench 231 to the left, and the wrench 231 drives the tension spring 260 to stretch, At the same time, the buckle 233 inside the wrench 231 blocks the draw-in groove of the knob 220 and rotates to the left, and each time the wrench 231 is moved to realize a 60° rotation; The original position recovered under the action of the tension spring 260 just falls into the next draw-in slot. Such reciprocating motion realizes the rotation of the knob 220, and then drives the adjustment wheel 210 to realize the conversion of several angles.

As shown in FIG. 11 , the middle lock assembly 300 includes a middle lock hand and a limit pin 260 connected with the middle lock handle 310 , and the middle lock assembly 300 also includes a handle sliding seat and a middle lock sleeve 340 .

The middle lock handle 310 is spirally connected with the handle sliding seat, the handle sliding seat is provided with a sliding seat pin 330, and the sliding seat pin 330 is set in the chute in the middle lock sleeve 340, and the front end of the middle lock sleeve 340 and the limit pin 260 connection, and the outer side of the limit pin 260 is covered with a middle lock spring, and the middle lock fixing screw fixes several components together along the direction of the arrow in the figure to form a complete middle lock assembly 300 .

The middle lock assembly 300 can be arranged at any balance position on the side of the box body 110. In this embodiment, the middle lock assembly 300 is arranged on the side of the box body 110 on the side opposite to the adjustment assembly 200, and the middle lock assembly 300 and the adjustment assembly 200 positions correspond. There is a lock hole 214 in the center of each adjustment surface, and the limit pin 260 is correspondingly connected and fixed with the lock hole 214. When the angle adjustment is completed, the adjacent two LED display cabinets 100 are fixed, which is convenient for operation and does not require auxiliary tools. .

In other embodiments, the middle lock assembly 300 of other structures can also be used to realize the fixing of the two LED display cabinets 100 .

As shown in Figures 12-17, the present invention can complete the splicing of two LED display cabinets 100 at different angles, including inner arc installation, 0-degree angle installation and outer arc installation. In this embodiment, the installation of an inner arc of 5°, an angle of 0°, and an outer arc of 5° can be realized, and the installation of other angles can also be realized through different inclination angles of the box side 110 and the inclination angle of the adjustment surface, and can also be installed at other angles by adding Adjust the number of surfaces to achieve splicing at more angles, which is not specifically limited here and the present invention is not limited thereto.

In this embodiment, by adjusting the adjustment wheel 210 at the upper and lower positions of the side surface 110 of the box body, each time the adjustment wheel 210 rotates 120 degrees, the installation of positive 5 degree angle, 0 degree angle and negative 5 degree angle is realized respectively. In the outer arc installation mode, the two side surfaces 110 of the box body are in contact, so the adjustment wheel 210 is hidden inside the side surfaces 110 of the box body.
