Description

Technical Field

[0001] The utility model relates to the technical field of moisture meter, in particular to a high-sensitivity trace moisture meter. Background Art

[0002] The moisture meter is designed based on the thermal weight principle. It is a new type of rapid moisture detection instrument. It can be widely used in all industries that require rapid moisture determination, such as medicine, grain, feed, seeds, rapeseed, dehydrated vegetables, tobacco, chemicals, tea, food, meat, textiles, agriculture, forestry, papermaking and other industries in laboratories and production processes.

[0003] In the existing trace moisture analyzer, when in use, the bottle containing the measured object is usually placed on the fixed frame of the instrument. However, if the liquid bottle is accidentally touched, the bottle body may still shake and tilt, which may affect the experiment.

[0004] In the prior art, a Chinese patent with publication number CN208383844U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a new type of trace moisture meter, including a meter base, a meter storage drawer is installed on the front surface of the meter base, slide rails are fixedly arranged on both sides of the meter storage drawer, a pulley is fixedly arranged on the inner end of the slide rail, a meter body is fixedly arranged on the top of the meter base, the meter base and the meter body are an integrated structure, and a display screen is arranged on the front surface of the meter body. The liquid of the instrument is placed The bracket is configured as a fixing clamp, which is clamped and fixed by the fixing clamp to prevent the liquid bottle from shaking or tilting during the measurement process, which would affect the measurement effect of the liquid in the bottle, making it easy to fix and disassemble the liquid bottle. A storage drawer is provided on the instrument, in which accessories of the printer in the instrument can be placed, and the measurement data at the printed location can be collected in the storage drawer of the measuring instrument to prevent loss, thereby improving the practicality of the instrument. However, if the external platform is not flat enough, the measuring instrument is prone to tilt and instability when placed, which in turn affects the measurement result and is inconvenient to carry. Summary of the invention

[0005] The purpose of the utility model is to provide a high-sensitivity trace moisture meter to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A high-sensitivity trace moisture meter comprises a protective cover and a meter body; a spirit level is fixedly mounted on one end of the protective cover, a movable plate is slidably mounted inside the protective cover, a sponge pad is attached to the top of the movable plate, the meter body is placed on the top of the sponge pad, a wiring port is opened at the other end of the meter body, a plurality of screws are threadedly mounted on the bottom of the protective cover, a support block is fixedly connected to the bottom of each screw, a top cover is arranged on the top of the protective cover, a handle is fixedly mounted on the top of the top cover, mounting blocks are fixedly connected to both sides of the protective cover, rotating blocks are rotatably mounted on both sides of the top cover, the rotating blocks and the mounting blocks are mutually engaged, a sponge layer is attached to the inside of the top cover, the sponge layer is fitted with the meter body, an adjustment component is arranged on the other end of the protective cover, the adjustment component is used to cover or reveal the wiring port.

Mounting blocks 101 are fixedly connected to both sides of the protective cover 1. Rotating blocks 201 are rotatably installed on both sides of the top cover 2. The rotating blocks 201 and the mounting blocks 101 are mutually engaged. A sponge layer 204 is attached to the inside of the top cover 2, and the sponge layer 204 is in contact with the measuring instrument body 5. An adjusting component 7 is provided at the other end of the protective cover 1, and the adjusting component 7 is used to cover or expose the docking interface 501. A handwheel 401 is fixedly installed on the periphery of each screw rod 4.

[0037] In this embodiment, after the user pulls out the movable plate 3 to the other side, the measuring instrument body 5 can move downward and come into contact with the inner wall of the protective cover 1. By installing the spirit level 6, the placement angle of the measuring instrument body 5 can be detected. At the same time, by rotating and adjusting each screw 4 respectively, the placement angle of the measuring instrument body 5 can be adjusted, thereby ensuring that the measuring instrument body 5 is placed horizontally, which is convenient for subsequent measurement work. By installing the sponge pad 303 and the sponge layer 204, the measuring instrument body 5 can be buffered and protected inside the protective cover 1 and the top cover 2 to prevent the measuring instrument body 5 from being damaged by impact. By installing the handle 202, the user's hand can be easily connected to the top cover 2, thereby facilitating the carrying of the measuring instrument body 5. By installing the handwheel 401, the contact area between the user's hand and the screw 4 can be expanded, thereby facilitating the rotation of the screw 4.
