Description

Technical Field

[0001] This utility model relates to the field of indoor display screens, specifically a heat-dissipating LED full-color indoor display screen. Background Technology

[0002] Indoor LED displays are LED displays specifically designed for indoor environments. They are characterized by their suitability for applications with small pixel pitch. Through the assembly of multiple LED modules, they achieve high-definition display, meeting customers' demands for clear images. Indoor LED displays are a modern advertising method that replaces traditional small television screens. They are widely used in indoor places with high foot traffic and are a new type of display that interacts with viewers and enhances product appeal. Due to their superior performance, indoor LED displays are widely used in various aspects of daily life. However, some problems have arisen during use that seriously affect the normal operation of the device, requiring solutions.

[0003] An existing type of easily heat-dissipating LED full-color indoor display screen uses multiple sets of guide fans at the bottom and multiple sets of exhaust fans at the top. When the display screen is working, the guide fans and exhaust fans can dissipate the heat generated inside the display screen, thereby achieving a cooling effect and extending the service life of the device.

[0004] However, for existing easy-to-heat-dissipate LED full-color indoor displays, in order to ensure the quietness of the display during use, the selected guide fans and exhaust fans should have a certain degree of quietness. However, fans with quietness are generally weak. When the display is large, if guide fans and exhaust fans with quietness are selected, it will affect the heat dissipation effect of the device to a certain extent, making the device unable to achieve the ideal usage effect. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an easy-to-heat-dissipate LED full-color indoor display screen to solve the technical problem of poor performance of existing easy-to-heat-dissipate LED full-color indoor display screens.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easily heat-dissipating LED full-color indoor display screen, comprising a display screen body, an air inlet at one end of the display screen body, an air outlet at the other end of the display screen body, a first rotating rod, a mounting base, and a second rotating rod arranged on one side inside the display screen body, a guide plate sleeved on the first rotating rod, a transmission rod sleeved inside the mounting base, a first vertical rod and a second vertical rod fixedly mounted on the transmission rod, a first sliding groove opened in the first vertical rod, a second sliding groove opened in the second vertical rod, a rotating block movably mounted on the second rotating rod, a first transmission wheel arranged on one side of the rotating block, a turntable fixedly mounted on one end of the rotating block, a rotating rod arranged on one side of the turntable, a motor fixedly mounted inside the display screen body, a rotating blade movably mounted on one end of the motor, a second transmission wheel fixedly mounted on one side of the rotating blade, and a belt sleeved inside the second transmission wheel.

[0007] By adopting the above technical solution, the problem of poor performance of existing heat-dissipating LED full-color indoor displays is solved. A motor is fixedly installed inside the display body, with a rotating blade movably mounted at one end of the motor. When the display is in use, the motor drives the blade to rotate, enhancing airflow inside the display body. This results in better heat dissipation through the air inlet and outlet, making the device more practical. A second drive wheel is also provided at one end of the rotating blade, with a belt fitted onto it. One end of the belt is movably mounted on a first drive wheel, which is fixedly mounted on the side of a rotating block.

The rotating rod is movably mounted in a second sliding groove, which is formed within a second vertical rod, which is fixedly mounted on the side of the drive rod. The transmission rod is movably installed inside the mounting base. When the blade rotates, it drives the rotating block and the rotating rod fixedly installed at one end of the rotating block to rotate via the belt. Since the rotating rod is movably installed in the second slide groove, it can drive the transmission rod to reciprocate inside the mounting base. A first vertical rod is also fixedly installed on one side of the transmission rod. The first vertical rod has a first slide groove, and a slide rod is fitted inside the first slide groove.

[0014] The present invention is further configured such that the first transmission wheel and the second transmission wheel are at the same distance from one side of the display screen body, and a belt is fitted on the side of both the first transmission wheel and the second transmission wheel.

[0015] Preferably, by setting the distance between the first and second drive wheels and one side of the display screen body to be the same, it is convenient to install the belt and make the device more practical. Both the first and second drive wheels are fitted with belts on their sides, so that the first and second drive wheels can be linked together. When the blade can drive the rotating block to rotate, the device can achieve the desired effect.

[0016] The present invention is further configured such that the length of the transmission rod is less than the width of the display screen body, and a limit block is provided on one side end of the second rotating rod.
