Description

Technical Field

[0002] Every food we taste in our daily lives has its optimal flavor at a specific temperature. Metal probes are thermometers developed to improve people's health and quality of life. The temperature of food is closely related to its taste and nutritional value. With societal development, food thermometers have greatly improved. Currently popular are barbecue thermometers, such as the one patented under "CN203848953U," which includes a thermometer body. One end of the thermometer body has two temperature probes, each with an L-shaped end and a U-shaped end. A circular plastic sleeve, smaller than the thermometer body and integrally formed with it, covers the upper part of each probe. The thermometer body includes an LCD display, a power button, a notification device, and a knob. A control circuit is located within the thermometer body. The two temperature probes, the power button, and the knob are electrically connected to the input of the control circuit, while the LCD display and the notification device are electrically connected to the output of the control circuit. A hanging ring is located on the top of the thermometer body. The temperature probe accurately monitors the baking process of food, ensuring that the food is fully cooked without waste. Moreover, the device is simple in structure, easy to operate, and low in cost.

[0043] The working principle of the metal probe rotation structure provided by this invention is as follows:

[0044] First step: When in use, rotate the rotating cover 2, which will drive the first connecting rod 3 to move. The first connecting rod 3 will then drive the connecting block 4 to move, and the connecting block 4 will then drive the second connecting rod 5 to move. This will cause the protective shell 51 and the metal probe 52 to move and detach from the storage slot on the shell 1. Since the first connecting rod 3 and the connecting block 4 are rotatably connected, they can be flipped over. Then rotate the protective shell 51 to detach it from the second connecting rod 5. After that, the metal probe 52 can be used for detection.

[0045] Second step: When the metal probe 52 is damaged and needs to be replaced, pull the handle 17 to move it so that the moving block 11 can be moved through the handle 17. When the moving block 11 moves, it will move the moving rod 14 and stretch the second telescopic spring 13. When the moving rod 14 moves, it will move the triangular block 15. Then, the triangular block 15 will compress the third telescopic spring 16. At the same time, because the triangular block 15 is away from the arc block 8, under the elastic action of the first telescopic spring 9, it will move the limiting plug 7, causing the limiting plug 7 to disengage from the limiting slot. Then the second connecting rod 5 can be taken out. The same operation can be used to limit and fix it.

[0046] Third step: When grinding is required, start the first drive motor 23 to operate, so that it can drive the first threaded rod 24 to rotate through the output shaft of the first drive motor 23. Under the action of the thread, the two first sliders 25 can be brought closer together, which pushes the second slider 28 to move upward. Under the action of the two fourth connecting rods 34, the two second mounting blocks 33 can be moved. The second mounting blocks 33 will drive the first mounting block 32 to move. The first mounting block 32 will drive the third slider 31 to move. Then, the third slider 31 will drive the third mounting block 35 and the clamping block 36 to move away from each other. Then, place the object in the work area. On platform 26, the two clamping blocks 36 can be brought closer together to clamp the object. The cylinder is activated to extend and retract, which drives the servo motor downward through the cylinder's output shaft. The servo motor is then activated to rotate the grinding wheel through its output shaft, thus grinding the object. During grinding, the second drive motor 37 can be activated to rotate the second threaded rod 38 through its output shaft. Under the action of the thread, the fourth slider 39 can move left and right, thereby adjusting the position of the housing 21 and the object, thus facilitating the grinding work.
