Description

[Technical Field]

[0001] The present invention relates to the technical field of LED display devices, and more particularly to an LED display device with high installation efficiency. [Background technology]

[0002] LED display devices are electronic display devices made up of LED dot matrices, and by flashing the lamp beads, they can instantly change the screen display content format, such as text, animation, pictures, and video. This allows for conversion between different formats of multiple information presentation modes, and they can be used both indoors and outdoors, offering advantages that are incomparable to other display devices. Due to their advantages of high brightness, low operating power consumption, low voltage requirements, small and convenient device size, long service life, stable impact resistance, and resistance to external interference, they have developed rapidly and are widely used in various fields.

[0003] At the same time, with the development of scientific and technological information, advances in video technology have been promoted, and video screen display has been widely applied in various fields such as outdoor advertising, public transportation, and promotional exhibitions. In order to increase the promotional effect, it is necessary to combine multiple display panels to display videos on the same screen.

[0004] Conventionally, when assembling multiple display panels, each display panel is generally manually fixed to a specific position on the same mounting frame, which has the following drawbacks: (1) Installation efficiency is low. The installation speed of a typical conventional LED display device is about 1m. 2 The duration is 37 minutes. (2) The installation accuracy must be strictly controlled. If the error is too large, some display panels may extend beyond the mounting frame, resulting in an unstable installation. (3) After installation is complete, the distance between adjacent display panels cannot be adjusted according to customer needs, making it inflexible to use. Summary of the Invention

[0005] To solve the above problems, the present invention provides an LED display device with high installation efficiency, in which two adjacent display panels are connected using a high-speed assembly part, and when connecting, simply align the two display panels and turn on the power, and the reduction motor rotates the screw, and the screw and nut can be used to shorten the distance between the two display panels until the required installation distance is reached, thereby improving installation efficiency.

[0006] To achieve the above object, the present invention provides an LED display device with high installation efficiency, which includes a plurality of display panels arranged in a matrix, two adjacent display panels being connected via a high-speed assembly component, the high-speed assembly component including an electric screw structure fixed to one of the two adjacent display panels and a nut structure fixed to the other of the two adjacent display panels. The motorized screw structure includes a reduction motor and a screw fixed to the display panel, and the output shaft of the reduction motor passes through a mounting sleeve fixed to the display panel and is connected to one end of the screw. The nut structure includes a nut that is fixed to the display panel via the mounting plate, and the nut is threaded onto the other end of the screw.

[0007] Preferably, an axial movement groove is provided at one end of the screw facing the reduction motor, and the output shaft of the reduction motor teeth Telescopic head and The expandable head extends inside the axial movement groove, is in sliding contact with the axial movement groove in the axial direction, and limits the degree of freedom of the axial movement groove in the circumferential direction.

[0008] Preferably, the telescopic head is a straight head or a D-shaped head, and the axial movement groove is a straight groove or a D-shaped groove that fits the telescopic head.

[0009] Preferably, a pressure spring is attached to the output shaft between the screw and the reduction motor, and the pressure spring is used to press the screw against the nut.

[0010] Preferably, the depth of the axial movement groove is greater than the length of the screw protruding from the mounting sleeve before being pushed into the mounting sleeve, so that the screw can be completely accommodated inside the mounting sleeve, thereby facilitating the alignment of multiple display panels positioned on the same horizontal line when installing the LED display device.

[0011] Preferably, an electric screw structure is fixed to both ends of opposite sides of the display panel, and a nut structure is fixed to both ends of the other opposite sides.

[0012] Preferably, the reduction motor, the mounting sleeve and the mounting plate are all fixed to the inside of the display panel via screws.

However, the present invention eliminates the need for a steel structure at the back, thereby achieving the goal of resource saving. (2) Reduce labor costs and reduce the number of wearers. (3) Improved installation efficiency, the installation speed of a typical conventional LED display device is about 1m 2 However, according to experimental verification, 2 The average installation speed is 5 minutes per unit, significantly improving installation efficiency.

As shown in Fig. 1, the LED display device with high installation efficiency includes a plurality of display panels 1 arranged in a matrix, and two adjacent display panels 1 are connected via a rapid assembly component. The rapid assembly component includes an electric screw structure 3 fixed to one of the two adjacent display panels 1 and a nut structure 2 fixed to the other of the two adjacent display panels 1.

As shown in FIG. 2, the electric screw structure 3 includes a reduction motor and a screw 34 fixed to the display panel 1, and an output shaft 38 of the reduction motor passes through a mounting sleeve 35 fixed to the display panel 1 and is connected to one end of the screw 34.

[0024] The nut structure 2 includes a nut 21 that is fixed to the display panel 1 via a mounting plate 22, and the nut 21 is threaded onto the other end of the screw .

[0025] Preferably, the screw 34 has an axial movement groove 36 at one end facing the reduction motor, and the output shaft 38 of the reduction motor teeth Telescopic head 37 and The expandable head 37 extends into the axial movement groove 36, slides against the axial movement groove 36 in the axial direction, and limits the degree of freedom of the axial movement groove 36 in the circumferential direction.

[0026] Preferably, the expandable head 37 is a straight head or a D-shaped head, and the axial movement groove 36 is a straight groove or a D-shaped groove that fits the expandable head 37 .

[0027] Preferably, a pressure spring 33 is attached to the output shaft 38 between the screw 34 and the reduction motor, and the pressure spring 33 is used to press the screw 34 against the nut 21 .

This makes it easier to align multiple display panels 1 located on the same horizontal line when installing the LED display device.

[0029] With this structure, when installing the LED display device, the display panels 1 must first be aligned horizontally. During this alignment process, the screw 34 is fully inserted into the mounting sleeve 35 (the telescopic head 37 moves into the axially movable groove 36, and the compression spring 33 is compressed at the same time), facilitating alignment. After this alignment is complete, the electric screw structure 3 is aligned with the nut structure 2, and the screw 34 is pressed against the nut 21 by the restoring force of the compression spring 33. In this embodiment, the screw 34 is just inserted into the nut 21. When the deceleration motor is subsequently started, it rotates the screw 34, which then uses the threads on the inner wall of the nut 21 to tighten the screw 34, thereby reliably connecting the two display panels 1. Rotating the screw 34 in the opposite direction separates the two adjacent display panels 1, facilitating separation.

[0030] Preferably, the electric screw structures 3 are fixed to both ends of the display panel 1 on opposite sides, and the nut structures 2 are fixed to both ends of the other opposite sides.

[0034] Therefore, the present invention employs an LED display device with the above-described structure, which has high installation efficiency, and two adjacent display panels are connected via high-speed assembly components. When connecting, simply align the two display panels and then turn on the power, and the reduction motor will rotate the screw, and the screw and nut can be used to shorten the distance between the two display panels until the required installation distance is reached, thereby improving installation efficiency.
