Description

TECHNICAL FIELD

[0001] The present application relates to the field of nixie tube, in particular to a split nixie tube display screen. BACKGROUND

[0002] The nixie tube display screen is an electronic display device mainly composed of LEDs (light emitting diodes), which are usually packaged together according to specific patterns and arrangements. According to the structure of the LED nixie tube, it can be divided into two categories: common cathode and common anode. The common cathode is an 8-segment display code that shares a negative electrode of a power supply, while the common anode is a 7-segment display code that shares a positive electrode of a power supply. By controlling the on-off of these LEDs, the nixie tube can present different numbers and symbols to realize information display. The nixie tube display screen is widely used in the field of household appliances, and its characteristics are economical, easy to use, and can display various digital information such as time, date, temperature by adjusting the input current and controlling the light of different pins.

[0003] The current nixie tube display screen design often uses one-piece molding technology. Although this design has a stable structure, its display content and layout are fixed. However, when applied to various household appliances, the display content and layout often differ due to different functions and needs of household appliances. The traditional one-piece molding display screen is difficult to adapt to the diversified display requirements of different household appliances due to its fixed nature. CONTENT OF THE INVENTION

[0004] The purpose of the present application is to provide a split nixie tube display screen composed of multiple independent nixie tube display modules, which are connected by dovetail structure.

[0005] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows: a split nixie tube display screen, comprising a plurality of display modules, each display module comprising a shell with a display pattern on the front face and a PCB board, the PCB board being provided with LED lamp beads corresponding to the display pattern, the PCB board being fixed in the shell, the outer side of the shell being provided with dovetail-shaped connecting blocks and connecting grooves matching the connecting blocks.

[0006] By adopting the above technical scheme, the different display modules are connected by the dovetail-shaped connecting blocks and connecting grooves, so that the nixie tube display modules can be flexibly combined into nixie tube display screens of different shapes and different display positions, meeting the display requirements of different household appliances, and improving the maintenance efficiency. The modular design makes the replacement of individual display modules more simple and efficient.

[0007] Preferably, the display modules include a digital display module for displaying digital content and a plurality of pattern display modules for displaying pattern content, the width of the digital display module is equal to twice the width of the pattern display modules, and the number of the connecting blocks and the connecting slots on the outer side of the digital display module is two.

[0008] By using the above scheme, the digital display module is arranged to enable the same side of the digital display module to be connected to two pattern display modules at the same time, so that the combination of different display modules is more flexible.

[0009] Preferably, one side of the connecting slot penetrates the back of the display module, the connecting block is located at the center of the outer side of the display module, the thickness of the connecting block is smaller than the thickness of the shell, and the connecting block is in interference fit with the connecting slot.

[0010] By using the above technical scheme, the connecting block and the connecting slot are arranged to make the front of the display module shell more flat, reduce the gap between different display modules, and when connected, the connecting block is inserted into the connecting slot from the back of the shell, and the interference fit between the two can make the connection more tight.

[0011] Preferably, a tight slot is formed on the connecting block, an insertion part for being inserted into the tight slot is arranged on the connecting slot correspondingly, the tight slot and the insertion part are matched, and rubber sheets are arranged on both sides of the tight slot, and the rubber sheets are used to contact both sides of the insertion part.

[0012] By using the above scheme, the cooperation between the tight slot and the insertion part can further improve the connection tightness of the connecting block and the connecting slot, and at the same time, the rubber sheets are extruded by the insertion part to make the friction between the rubber sheets and the insertion part greater, so that the connection between the pattern display module and the digital display module is more tight.

[0013] Preferably, a wiring slot is further formed on the back of the shell, the wiring slot is located on the same side of the connecting block and the connecting slot, and the wiring slot penetrates the side of the shell.

[0014] By using the above scheme, the arrangement of the wiring slot makes the wiring of the display module more convenient.

[0015] In summary, the beneficial technical effects of the present application are:

[0016] The different display modules are connected through the combination of the connecting blocks and the connecting grooves, so that the nixie tube display modules can be flexibly combined into nixie tube display screens with different shapes and different display positions, the problem of meeting different household appliance display requirements is solved, and the connecting blocks and the connecting grooves are arranged to be closely connected, so that the front surface of the display module shell is more flat, the connecting blocks are hidden, the gap between the different display modules is reduced, and the maintenance efficiency is improved.
