Embodiment 1

[0021] Such as figure 1 , figure 2 , image 3 As shown, a button mechanism for a forehead temperature gun includes a housing 1 and a button panel 2 with a circular structure. The housing 1 is provided with a circular structure mounting hole 3 for installing the button panel 2. The mounting hole The center position of 3 is provided with support column 4, and support column 4 is fixedly connected with three elastic connecting rods 5 that are evenly distributed around the central column, and the upper end of support column 4 protrudes upwards relative to elastic connecting rod 5, and elastic connecting rod 5 is connected with the mounting hole. 3. The inner wall is fixedly connected. The elastic connecting rod 5 is composed of three connecting rods 6 fixedly connected in sequence. The angle formed between the connecting rod 6 near the supporting column 4 and the connecting rod 6 in the middle is 30-90°, which is in line with the described The angle formed between the connectin...

Abstract

The invention provides a key mechanism for a forehead thermometer in allusion to the defect that three control switches on a forehead thermometer need to be controlled by three independent keys in theprior art, and belongs to the technical field of forehead thermometers. The key mechanism comprises a shell and a key panel of a circular structure, wherein a circular structure mounting hole used for mounting the key panel is formed in the shell, a supporting column is arranged in the center of the mounting hole, at least three elastic connecting rods evenly distributed around the center columnare fixedly connected to the upper end of the supporting column, and the elastic connecting rods are fixedly connected with the inner wall of the mounting hole; and the key panel is movably arranged in the mounting hole, a gap is reserved between the peripheral side surface of the key panel and the inner wall of the mounting hole, and a stress bump is arranged between the lower end surface of thekey panel and each elastic connecting rod. According to the invention, a plurality of control switches can be respectively controlled by arranging one key panel, and the operation is relatively simpleand convenient.

Description

technical field [0001] The invention belongs to the technical field of forehead temperature guns, and in particular relates to a button mechanism for forehead temperature guns. Background technique [0002] Forehead thermometer, also known as infrared thermometer, is an electronic instrument used to measure body temperature. It is very simple and convenient to use, does not need to touch human skin, avoids cross-infection, measures temperature with one button, and checks for influenza. The forehead thermometer is widely used in various places because it can measure body temperature without contact and is small and portable. The forehead temperature gun is generally equipped with three control switches. In order to control these three control switches, the existing forehead temperature gun needs to be provided with three independent buttons, and the structure is relatively complicated. Contents of the invention [0003] The present invention aims at the drawback that the t...
