Description

Magnetic touch mounting structure, display screen box body and LED display screen

Technical Field

This application belongs to display screen technical field, and more specifically says so relates to a mounting structure, display screen box and LED display screen are bumped to magnetism.

Background

In the currently common LED display screen, a plurality of display screen boxes are usually included, and these display screen boxes can be assembled with each other to form the LED display screen. Each display screen box all includes the box frame and installs the display module assembly that can splice each other on the box frame. Wherein, display module assembly includes display module and drain pan, and display module is range upon range of and passes through connection structure spacing connection with the drain pan. Here, the display module refers to the PCBA product that LED lamp pearl that a face pasted and regularly arranged, IC components and parts are installed to the another side subsides.

At present, the fixing mode of the display module mainly has two types, namely a bolt connecting mode and a magnetic suction connecting mode, and the two connecting modes respectively have advantages and disadvantages. To bolted connection mode, because the display module assembly need can only install or dismantle to the back of LED display screen, so its installation and later maintenance are not very convenient. To the connection mode of magnetism, because can stand and directly find the display module assembly that can not normally show before the LED display screen face and dismantle, so its display module assembly's installation and maintenance are all comparatively convenient. However, when adopting magnetism to inhale connected mode, although display module assembly and box frame's dismantlement, maintenance are comparatively convenient, but connection between the two is not very stable, especially when display module assembly's drain pan receives the exogenic action, often can take place the separation between display module assembly and the box frame, leads to the display screen box to drop, damage, and then brings the unnecessary loss for the user. Therefore, the LED display screen adopting the magnetic attraction connection mode is more suitable for being used indoors generally; in the open air, especially in the occasions where people flow, due to the safety consideration, the display module of the LED display screen is usually in a bolt connection mode, so that the display module adopting the magnetic connection mode is prevented from being stripped off and falling off from the installation position due to negative pressure formed by leeward, and further safety accidents can be effectively avoided.

The problem that the display module assembly that connects is easily dropped to magnetism can increase some installation fixed measures usually in order to strengthen the connection stability between display module assembly and the box frame. For example, can increase the safety rope between display module assembly and box frame and make both link together, but this mode can only ensure that display module assembly can not drop and cause the incident, nevertheless can not guarantee that display module assembly can not break away from the box frame, and in case display module assembly breaks away from behind the frame, just need maintain LED display screen again, has increased the later maintenance cost. In addition, the display module can be fixed by adding the knob lock, although the mode can realize front unlocking of the display module (generally, an inner hexagonal wrench penetrates through the display module to lock or unlock the knob lock) and ensures that the display module cannot fall off, an unlocking avoiding hole of the knob lock needs to be reserved on the display module, and therefore the mode is only suitable for large-space display screens and not suitable for small-space display screens.

Therefore, how to make the display module assembly and the box frame be connected more stably and the installation of display module assembly is more convenient and can be suitable for the booth apart from the display screen, and then the maintenance convenience of reinforcing the display screen box has just become the problem that this technical field needs a solution urgently.
