Description

Technical Field

[0001] The utility model relates to the technical field of grain pile temperature and humidity detection, in particular to a handheld grain pile temperature and humidity detection device. Background Technique

[0002] During the storage of grain, if the temperature and humidity are too high or too low, it may cause problems such as spontaneous combustion, mildew, and deterioration of grain quality. In order to prevent pests and mildew, ensure safe storage, control storage conditions, and conduct quality inspections, a handheld device is generally used to measure the temperature of grain, which helps to ensure the quality, safety, and nutritional value of grain and extend the storage period of grain. However, at present, the grain pile detector on the market has a single function. When detecting, the staff needs to view the data according to the direction of the display part. When detecting different positions of the grain pile with a complex shape, the angle of the display part is not necessarily perpendicular to the line of sight of the staff. Therefore, the staff needs to change different angles to observe the display part.

[0054] Specific working process:

[0055] First, put the spring 202 on the fixed cylinder body 201. There is a step on the movable cylinder body 3 that can limit the upper limit of the spring 202. Then, insert one side of the first limit groove 2032 of the limit collar 203 into the limit post of the fixed cylinder body 201 to restrict the rotation of the limit collar 203. At the same time, the inner step of the limit collar 203 contacts the lower end of the spring 202. The inner diameter of the limit collar 203 and the outer diameter of the fixed cylinder body 201 are assembled flexibly without shaking. Push the limit collar 203 upward to squeeze the spring 202 to deform and contract, so that the rotation shaft hole of the fixed cylinder body 201 is exposed. Then, insert the fixed cylinder body 201 into the movable cylinder body 3. The rotation shaft holes of the fixed cylinder body 201 and the movable cylinder body 3 are concentrically inserted with a rotation pin 204. The rotation pin 204 is threadedly connected to the rotation shaft hole of the fixed cylinder body 201, and the rotation between the rotation pin 204 and the rotation shaft hole of the movable cylinder body 3 is flexible without jamming.

[0056] When the display unit 1 and the movable cylinder body 3 form an angle of 180°, under the action of the spring 202, the limiting protrusion 2031 of the limiting sleeve 203 is inserted into the second limiting groove 301 at the upper end of the movable cylinder body 3, and then the limiting sleeve 203 is pushed to squeeze the spring 202 to deform and contract. At this time, the limiting protrusion 2031 of the limiting sleeve 203 disengages from the second limiting groove 301 at the upper end of the movable cylinder body 3, and the movable cylinder body 3 is rotated 90° around the rotating pin 204. Then, the limiting sleeve 203 is released so that the limiting protrusion 2031 of the limiting sleeve 203 is inserted into another second limiting groove 301 of the movable cylinder body 3.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
