Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a magnetic display screen connection mechanism with positioning assistance. Background Technology

[0002] A display screen is an electronic device used to display information such as images, videos, and text. It is widely used in various scenarios such as televisions, computers, mobile phones, tablets, billboards, and dashboards. According to different display technologies, it can be divided into several types, including liquid crystal displays (LCDs), organic light-emitting diode displays (OLEDs), plasma displays (PDPs), and electronic paper. Among them, LCDs and OLEDs are the most common. LCDs control the passage of light through a backlight and the arrangement of liquid crystal molecules to display images, while OLEDs directly excite organic materials to emit light through current, resulting in a wider color gamut, higher contrast, and a thinner structure. The performance indicators of a display screen include resolution, refresh rate, brightness, contrast ratio, color gamut, and response time. These indicators directly affect the display effect and user experience. With the advancement of technology, displays are developing towards higher resolution, lower power consumption, thinner and lighter designs, and greater flexibility.

[0003] LED displays typically consist of multiple LED modules, driver circuits, control systems, etc. To protect these internal components, they are usually protected by a frame and a back cover. However, the back cover is usually fixed with bolts, which makes the installation and disassembly process cumbersome and reduces the efficiency of subsequent maintenance. Therefore, we propose a magnetic display connection mechanism with positioning assistance. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a magnetic display screen connection mechanism with positioning assistance.

[0005] This utility model is achieved using the following technical solution: a magnetic display screen connection mechanism with positioning assistance, comprising a frame, an LED display screen fixedly installed on the inner wall of the frame, a rear cover plate provided at the rear end of the frame, positioning holes provided at the four corners of the rear end of the frame, positioning rods inserted into the inner walls of the positioning holes, mounting holes provided at both the left and right ends of the frame, magnetic sleeves fixedly connected to the inner walls of the mounting holes, and limit components provided at both the left and right ends of the rear cover plate.

[0006] The limiting component includes a mounting plate, one end of which is provided with a limiting ring, and one end of the limiting ring is fixedly connected to a magnetic suction rod.

[0007] The above technical solution involves inserting the positioning rod into the positioning hole to position the rear cover plate, facilitating subsequent installation. The magnetic rod is then inserted into the magnetic sleeve and magnetically fixed to it, thereby securing the rear cover plate. The operation is simple and convenient, improving installation efficiency.

[0008] As a further improvement to the above solution, one end of the mounting plate is fixedly connected to the surface of the rear cover plate, and the surface of the magnetic rod is slidably connected to the inner wall of the mounting plate.

[0009] The above technical solution ensures the stability of the magnetic rod during movement by sliding the magnetic rod to the inner wall of the mounting plate.

[0010] As a further improvement to the above solution, the end of the magnetic rod away from the limiting ring extends to the inner wall of the mounting hole and magnetically attracts the magnetic sleeve.

[0011] Through the above technical solution, the magnetic attraction between the magnetic rod and the magnetic sleeve effectively prevents the magnetic rod from detaching from the inside of the mounting hole, ensuring the stability of the back cover after installation.

[0012] As a further improvement to the above solution, the number of mounting holes is set to four, and the four mounting holes are symmetrically distributed around the frame.

[0013] The above technical solution ensures that the number of limiting components corresponds to the number of mounting holes, thereby improving the stability after installation.

[0014] As a further improvement to the above solution, the size of the positioning hole is adapted to the size of the positioning rod, and the rear end of the positioning rod is fixedly connected to the front end of the rear cover plate.

[0015] With the above technical solution, four positioning holes and four positioning rods are provided. When the four positioning rods are inserted into the positioning holes, the movement of the rear cover plate during installation can be effectively prevented.

[0016] As a further improvement to the above solution, a ventilation opening is provided at the rear end of the rear cover, and a dustproof mesh is magnetically attached to the inner wall of the ventilation opening.

[0017] The above technical solution improves ventilation efficiency and ensures good heat dissipation through the ventilation openings in the rear cover. The dustproof net prevents dust from entering the rear cover and affecting the LED display and electronic components.

[0018] As a further improvement to the above solution, the rear end of the dustproof net is fixedly connected to a tie rod.

[0019] The above technical solution allows for easy movement of the dustproof net by pulling the lever, and facilitates quick disassembly of the dustproof net, thus improving the convenience of operation.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model, through the setting of a frame, a rear cover plate, a positioning rod, a magnetic sleeve, and a limiting component, specifically, during the installation of the rear cover plate, inserts the positioning rod into the positioning hole to position the rear cover plate, facilitating subsequent installation. The magnetic rod is inserted into the magnetic sleeve and magnetically fixed thereto, thereby fixing the rear cover plate in place. The operation is simple and convenient, improving installation efficiency. Because the magnetic rod and the magnetic sleeve are magnetically attracted, the magnetic rod is effectively prevented from detaching from the installation hole, ensuring the stability of the rear cover plate after installation.

[0022] This utility model uses a limiting component, specifically a limiting ring to pull the magnetic rods to move, thereby canceling the magnetic fixation between the magnetic rods and the magnetic sleeve. This allows the four magnetic rods to be disassembled and removed. At this point, the rear cover can be pulled to the right to disassemble, improving disassembly efficiency and facilitating subsequent inspection and maintenance.

[0023] This utility model improves ventilation efficiency and ensures good heat dissipation by setting a rear cover plate and a dustproof net. Specifically, the ventilation openings in the rear cover plate improve ventilation efficiency and ensure good heat dissipation. The dustproof net prevents dust from entering the rear cover plate and affecting the LED display and electronic components. Since the dustproof net is magnetically installed, it is easy to quickly remove and clean. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0033] Example:

[0034] Please combine Figure 1-6 This embodiment of a magnetic display screen connection mechanism with positioning assistance includes a frame 1, an LED display screen 2 fixedly installed on the inner wall of the frame 1, a rear cover plate 3 provided at the rear end of the frame 1, positioning holes 4 opened at the four corners of the rear end of the frame 1, positioning rods 5 inserted into the inner wall of the positioning holes 4, mounting holes 6 opened at both the left and right ends of the frame 1, magnetic sleeves 7 fixedly connected to the inner wall of the mounting holes 6, and limit components 8 provided at both the left and right ends of the rear cover plate 3.

[0035] The limiting component 8 includes a mounting plate 801. One end of the mounting plate 801 is provided with a limiting ring 802. One end of the limiting ring 802 is fixedly connected to a magnetic suction rod 803. By pulling the magnetic suction rod 803 through the limiting ring 802, the magnetic attraction between the magnetic suction rod 803 and the magnetic sleeve 7 is canceled, and the four magnetic suction rods 803 can be disassembled and removed. At this time, the rear cover plate 3 can be disassembled by pulling it to the right, which improves the disassembly efficiency and facilitates subsequent inspection and maintenance. When installing the rear cover plate 3, the positioning rod 5 is inserted into the positioning hole 4 to position the rear cover plate 3, which facilitates subsequent installation. The magnetic suction rod 803 is inserted into the magnetic sleeve 7 and magnetically attracted to it, thereby installing and fixing the rear cover plate 3. The operation is simple and convenient, improving the installation efficiency. Since the magnetic suction rod 803 is magnetically attracted to the magnetic sleeve 7, it effectively prevents the magnetic suction rod 803 from detaching from the inside of the mounting hole 6, ensuring the stability of the rear cover plate 3 after installation.

[0036] One end of the mounting plate 801 is fixedly connected to the surface of the rear cover plate 3, and the surface of the magnetic rod 803 is slidably connected to the inner wall of the mounting plate 801.

[0037] The end of the magnetic rod 803 away from the limiting ring 802 extends to the inner wall of the mounting hole 6 and magnetically attracts the magnetic sleeve 7.

[0038] There are four mounting holes 6, which are symmetrically distributed around the frame 1.

[0039] The size of the positioning hole 4 is matched with the size of the positioning rod 5, and the rear end of the positioning rod 5 is fixedly connected to the front end of the rear cover plate 3.

[0040] The rear end of the rear cover plate 3 is provided with a ventilation opening 9. The inner wall of the ventilation opening 9 is magnetically attached with a dustproof mesh 10. The ventilation opening 9 provided by the rear cover plate 3 improves the ventilation efficiency and ensures good heat dissipation. Since the dustproof mesh 10 is magnetically installed, it is easy to quickly remove and clean it.

[0041] The rear end of the dustproof net 10 is fixedly connected to the tie rod 11.

[0042] The implementation principle of the magnetic display screen connection mechanism with positioning assistance in this embodiment is as follows: When the back cover plate 3 needs to be disassembled, the magnetic rod 803 is moved by the limiting ring 802, and the magnetic attraction between the magnetic rod 803 and the magnetic sleeve 7 is canceled. The four magnetic rods 803 are then removed. At this time, the back cover plate 3 can be disassembled by pulling it to the right, which improves the disassembly efficiency and facilitates subsequent inspection and maintenance. When installing the back cover plate 3, the positioning rod 5 is inserted into the positioning hole 4 to position the back cover plate 3, which facilitates subsequent installation. The magnetic rod 803 is inserted into the magnetic sleeve 7 and magnetically attracted to it. The magnetic sleeve 7 secures the rear cover plate 3, making the installation simple and convenient and improving installation efficiency. The magnetic attraction between the magnetic rod 803 and the magnetic sleeve 7 effectively prevents the magnetic rod 803 from detaching from the mounting hole 6, ensuring the stability of the rear cover plate 3 after installation. The ventilation opening 9 on the rear cover plate 3 improves ventilation efficiency and ensures good heat dissipation. The dustproof net 10 prevents dust from entering the rear cover plate 3 and affecting the LED display screen 2 and electronic components. The magnetic installation of the dustproof net 10 facilitates quick disassembly and cleaning.

[0043] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
