Description

LED display device

Technical Field

The utility model relates to a LED shows technical field, specifically indicates a LED display device.

Background

The LED display device is widely applied to various household appliances and industrial controllers, in the field of manufacturing of intelligent microcomputer controllers of the household appliances, in order to meet the visual effect of customers, the LED digital display device needs to be processed and molded in the traditional production and manufacturing process, and is assembled and produced through an auxiliary plastic base.

At present, when the LED digital display tube is fixed with the plastic base, no matter the LED digital display tube is horizontally or obliquely arranged, the metal pin can generate an upward acting force on the LED digital display tube, so that the LED digital display tube can rebound upwards, and the assembly is poor.

Therefore, a good fixation between the LED digital display tube and the plastic base needs to be solved.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a technical scheme does: the LED display device comprises an LED digital display tube and a base which are matched with each other, wherein a metal pin is arranged at the lower end of the LED digital display tube.

As an improvement, bosses are arranged at four corners of the lower end face of the LED digital display tube, and recesses matched with the bosses are arranged at four corners of the upper end face of the base.

As an improvement, the number of the metal pins is multiple, the through holes and the metal pins are arranged in a one-to-one correspondence manner and symmetrically arranged on the side walls of the front side and the rear side of the base.

After the structure more than adopting, the utility model has the advantages of as follows:

the utility model fixes the LED digital display tube and the base together by the interference fit formed by the metal pin passing through the through hole, thereby realizing the beneficial effect of good fixation of the LED digital display tube and the plastic base; meanwhile, the LED digital display tube can be used without re-opening the die, and has good applicability.

The utility model discloses simple structure, convenient to use, the joint assembly of being convenient for has improved assembly production efficiency, has reduced assembly cost, has improved economic benefits, and the practicality is strong.
