Indoor humidity measuring instrument

Abstract

The invention discloses an indoor humidity measuring instrument. The humidity measuring instrument comprises a fixing plate, and a hygrothermograph dial plate is arranged on one side of the fixing plate; a first rectangular groove and a second rectangular groove are formed in the other side of the fixing plate; and a through hole is formed in the upper portion of the fixing plate, gear containinggrooves are formed in the fixing plate and in the two sides of the first rectangular groove, first rotating shafts are arranged in the gear containing grooves, a first gear and a second gear are arranged on the two sides of the first rectangular groove correspondingly, and a rectangular toothed plate is arranged in the first rectangular groove. According to the humidity measuring instrument, upward movement of the rectangular toothed plate is limited through meshing of the rectangular toothed plate and the gears and the braking effect of a clamping strip, and the restraining and supporting effects are achieved through a rectangular supporting plate and a fixing baffle; and a sliding block is pushed downwards through a pressure spring, a torsion spring enables a first fixing clamping plateto rotate downwards and enables a second fixing clamping plate to rotate upwards, and therefore other plate-shaped objects can be clamped through two faces, and the hanging function is achieved.

Description

technical field [0001] The invention relates to a humidity measuring instrument, in particular to an indoor humidity measuring instrument. Background technique [0002] The humidity thermometer is used to measure the temperature and humidity of the environment to determine the environmental conditions of product production or storage. It is also used in people's daily life. Traditional indoor thermometers and hygrometers rely on movable brackets to support themselves, and put them on the table in a static state to play a stable role. Generally, the shape of indoor humidity thermometers is designed as a circle. When the dial of the humidity thermometer is placed on the table, the humidity thermometer There is only one point of force, so it is easy to shake when placed in this way, and often loses the center of gravity, causing the dial to overturn, and eventually damages the dial. Secondly, the placement angle of the traditional indoor humidity thermometer cannot be adjusted...

Traditional indoor thermometers and hygrometers rely on movable brackets to support themselves, and put them on the table in a static state to play a stable role. Generally, the shape of indoor humidity thermometers is designed as a circle. When the dial of the humidity thermometer is placed on the table, the humidity thermometer There is only one point of force, so it is easy to shake when placed in this way, and often loses the center of gravity, causing the dial to overturn, and eventually damages the dial. Secondly, the placement angle of the traditional indoor humidity thermometer cannot be adjusted, and cannot be adjusted according to needs. , in order to make the temperature and humidity meter placed on the desktop more stable and firm, the angle of the dial of the temperature and humidity meter can be adjusted when placing it, and the hanging function can be realized by clamping other objects. Therefore, a new type of indoor humidity measuring instrument is proposed
