Description

Technical Field

[0001] The utility model belongs to the technical field of LED display devices, and specifically belongs to the mechanical movement telescopic unit of an LED display screen. Background Art

[0002] The telescopic unit of an LED display screen is widely used in various public places. By adopting precise space-time combination control technology, it effectively expands the viewing space, synchronously displays multiple pictures, completely eliminates the viewing dead zone. At the same time, the dynamic display screen can produce more complex telescopic and moving effects, which can attract people's attention more.

[0003] Most of the existing telescopic units of LED display screens have complex structures, occupy a large space, and cannot achieve fast transmission. During the telescopic movement, they cannot achieve magnification telescoping, resulting in an unsmooth telescopic process and affecting the final display effect of the LED display screen.

[0004] To solve the above problems, the inventor applied for a magnification telescopic unit of a mechanical matrix screen for an LED display screen (Application No.: CN202120118238.X). However, the telescopic unit structure provided by this patent is still relatively complex, with many components and high production costs. Therefore, the inventor further optimized it on the basis of this patent and proposed a mechanical movement telescopic unit for an LED display screen. Summary of the Utility Model

[0005] In view of this, the purpose of the present utility model is to overcome the deficiencies in the prior art and provide a mechanical movement telescopic unit for an LED display screen. The present application provides the following technical solutions:

[0006] It includes a first aluminum alloy housing and a second aluminum alloy housing in a C shape. The openings of the first aluminum alloy housing and the second aluminum alloy housing are fitted with male and female tenons to form a square-shaped cylinder. A stepping motor is installed in the cylinder, and a central telescopic tube for installing an LED display screen is slidably arranged. The stepping motor is used to drive the central telescopic tube to perform a cyclic telescopic movement in the cylinder.

[0007] It further includes a front end plate and a rear end plate. Corresponding bolt holes are provided between the front end plate and the rear end plate and the cylinder. The front end plate and the rear end plate are respectively bolt-fixed to the front and rear parts of the cylinder. A through groove matching the central telescopic tube is opened on the front end plate, and the central telescopic tube passes through the through groove for telescopic movement.

[0008] By bolt-connecting and fixing the front end plate and the rear end plate at the front and rear parts of the cylinder, the connection strength between the first aluminum alloy housing and the second aluminum alloy housing is enhanced, making their connection more stable, so that when multiple telescopic units are used in combination, they have sufficient strength and are not easily damaged, deformed, or disassembled.

[0009] A pulley mounting plate is provided inside the opening of the first aluminum alloy housing and the second aluminum alloy housing. A plurality of pulleys are mounted on the pulley mounting plate, and pulley guide grooves are provided on both the upper and lower sides of the central telescopic tube; the pulley guide grooves are in contact and cooperation with the pulleys.

[0010] The central telescopic tube is installed by using pulleys and pulley guide grooves to realize the sliding setting of the central telescopic tube, and the movement of the central telescopic tube is relatively smooth.

[0011] A motor mounting socket is provided inside the cylinder body, and the stepping motor is mounted on the motor mounting socket.

[0012] Sockets are provided inside the first aluminum alloy housing or the second aluminum alloy housing. The upper and lower sides of the motor mounting socket are inserted and installed in the sockets; a flange is provided on one side of the motor mounting socket close to the front end plate, and a corresponding slot is provided on the front end plate, and the flange is engaged in the slot.

[0013] By setting the motor mounting socket in the above manner, the motor mounting socket can be detachably fixed, and the stepping motor is mounted on the motor mounting socket, that is, the stepping motor can also be disassembled and assembled together with the motor mounting socket.

[0014] A synchronous belt mounting plate is provided on the side of the central telescopic tube. A synchronous belt is bonded to the synchronous belt mounting plate. A synchronous pulley is provided on the main shaft of the stepping motor, and the synchronous pulley is in cooperation with the synchronous belt.

[0015] The first aluminum alloy housing and the second aluminum alloy housing have the same shape. During production, only one shape of aluminum alloy profile needs to be produced, and the production cost is lower. At the same time, when the first aluminum alloy housing and the second aluminum alloy housing as the outer shell are damaged, the same aluminum alloy profile can be used to repair and replace the two parts.

[0016] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0017] The structure is more concise, the production and manufacturing cost is lower, the components are connected in a assembled manner to form an integral body, the disassembly and assembly are convenient, and the maintenance cost is low.
