Description

Technical Field

[0001] The utility model relates to the technical field of temperature measurement, in particular to a portable metering device. Background Art

[0002] In the medical field, portable thermometers can be used to quickly measure body temperature, especially in disease monitoring, first aid and daily health management. Today's common electronic thermometers or infrared thermometers all fall into the category of portable thermometers. In the catering industry and food production field, portable thermometers can be used to detect and monitor the temperature of food to ensure the safety and quality of food storage, processing and service. For example, they can detect the cooking temperature, refrigeration and freezing temperature of food. In the industrial production process, portable thermometers can be used to monitor the operating temperature of equipment and machinery, as well as to diagnose and prevent equipment failures. For example, in the metallurgical, electronic manufacturing and chemical industries, temperature monitoring is crucial to production efficiency and product quality.

[0003] Thermometers are usually equipped with a liquid crystal display to display the measured temperature value. The display screen is usually designed with readability and energy consumption in mind to ensure that temperature data can be clearly displayed under various lighting conditions. Some thermometers may be equipped with connection interfaces, such as USB interfaces or other data transmission interfaces, for data transmission or charging. The casing of the thermometer is usually made of durable plastic or metal to protect the internal electronic components from physical damage and environmental impacts. The casing design usually takes into account portability and ease of operation, and may include a handle for easy grip or a surface design to provide a good feel and anti-slip properties.

[0004] Traditional thermometers are large, heavy, fragile, and easily broken. Due to these physical characteristics, they need to be used with caution to avoid damage. In addition, the measurement methods of traditional thermometers also have certain limitations. They can usually only provide an instantaneous temperature reading and cannot provide continuous temperature monitoring. Moreover, this type of thermometer is also insufficient in measurement accuracy. They can usually only provide accuracy to degrees Celsius or Fahrenheit and cannot provide more precise temperature numbers, making traditional measuring devices inconvenient to carry. Utility Model Content

[0005] In order to make up for the above deficiencies, the present invention provides a portable metering device, which aims to improve the problem that traditional metering devices are inconvenient to carry.

[0006] The cam is fixedly provided with a toothed plate, and the toothed plate is meshed with the toothed plate, and the toothed plate is meshed with the toothed plate.

[0007] Furthermore, the connecting assembly includes a fixing plate, and the side wall of the fixing plate is fixedly connected to the bottom of the display screen.

[0008] Furthermore, one end of the fixed plate is fixedly connected to a fixed bar, and a side wall of the fixed bar is rotatably connected to a rotating plate.

[0009] Furthermore, a sliding groove is provided inside the fixing bar, a fixing block is fixedly connected to the side wall of the fixing plate, and a connecting column is fixedly connected to the side wall of the fixing bar.

[0010] Furthermore, the top of the fixed block is rotatably connected to gear 2, the top of the rotating plate is rotatably connected to a slider, the side wall of the slider is slidably connected to the inside of the slide groove, and one end of the connecting column is slidably connected to rack 3.

[0011] Furthermore, a rotating column is rotatably connected inside the rotating plate, the rack three is meshed with the gear two, and the side wall of the rack three is slidably connected to the top of the fixed block.

[0012] Furthermore, a connecting plate is fixedly connected to the outer wall of the rotating plate, and the side wall of the connecting plate is fixedly connected to the side wall of the fixed block.

[0013] Furthermore, a connecting block is fixedly connected to the side wall of the rotating plate.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the present invention, the sliding column is first pulled to move, thereby driving the rack 2 to move. Since the two gears 1 and the rack 2 are meshed with each other, and each gear 1 is meshed with the rack 1, as the rack 2 moves, the gear 1 rotates, driving the moving column to move. Finally, the baffle will clamp the gear 1 to limit the movement of the sliding column. The movement of the moving column is limited by the cooperation of the clamping column and the positioning hole, thereby achieving a telescopic effect, solving the inconvenience problem of the traditional temperature measuring device and improving the portability and flexibility of the temperature measuring device.

[0016] 2. In the present invention, the slider slides stably in the slide groove by rotating the rotating plate, and the connecting plate and the rotating column cooperate with each other to ensure that the rotating plate remains relatively stable during movement. During this process, due to the mutual engagement of rack three and gear two, rack three slides out from the inside of the connecting column, and finally the connecting block and the interface are engaged with each other to complete the protection of the interface, thereby achieving the effect of isolating the interface from the external environment, solving the problem that the traditional interface is damaged due to external environmental pollution, and even causing safety accidents, thereby improving the safety of the device and extending the service life of the interface.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a portable metering device, including a display screen 1, a sliding column 2 is fixedly connected to the side wall of the display screen 1, and a moving column 3 is slidably connected to the outer wall of the sliding column 2, one end of the sliding column 2 is fixedly connected to a rack 2 6, and one end of the rack 2 6 is fixedly connected to a baffle 23, and the outer wall of the moving column 3 is slidably connected to the fixed column 4, and the side wall of the moving column 3 is fixedly connected to a plurality of support plates 8, and the side wall of each support plate 8 is rotatably connected to a gear 1 7, and the rack 2 6 is meshed with the outer wall of the gear 1 7, and one end of the moving column 3 is fixedly connected to a card column 9, and a plurality of racks 5 are fixedly connected to the inside of the fixed column 4, and the rack 5 is meshed with the outer wall of the gear 1 7. A plurality of positioning holes 10 are opened on the side wall of the fixed column 4, and the card column 9 is fitted with the inner wall of the positioning hole 10. A connecting component is provided inside the display screen 1, and the connecting component is used to connect the interface protection cover to the side wall of the display screen 1.

[0025] Specifically, by manipulating the movement of the sliding column 2, the rack 2 6 can be made to move synchronously therewith. In view of the meshing relationship between the two gears 1 7 and the rack 2 6, and the meshing state of the gear 1 7 and the rack 1 5, the movement of the rack 2 6 will drive the gear 1 7 to rotate. Through the coordinated action of the gear 1 7 and the rack 1 5, the support plate 8 can be driven to cause the moving column 3 to be displaced. As the rack 2 6 moves, the baffle 23 will limit its further movement and lock the rotation of the gear 1 7, thereby limiting the movement range of the sliding column 2 and the moving column 3. Finally, by pressing the clamping column 9, its position is adjusted to determine the telescopic length, and the engagement relationship between the clamping column 9 and the positioning hole 10 will fix the moving column 3, thereby completing the telescopic process, thereby significantly improving the portability and flexibility of the temperature measuring device.

[0026] Reference Figure 3 and Figure 4The connecting component includes a fixed plate 12, the side wall of the fixed plate 12 is fixedly connected to the bottom of the display screen 1, one end of the fixed plate 12 is fixedly connected to a fixed bar 13, the side wall of the fixed bar 13 is rotatably connected to the rotating plate 11, a slide groove 14 is opened inside the fixed bar 13, the side wall of the fixed plate 12 is fixedly connected to a fixed block 16, the side wall of the fixed bar 13 is fixedly connected to a connecting column 17, the top of the fixed block 16 is rotatably connected to a gear 2 19, the top of the rotating plate 11 is rotatably connected to the slider 15, the side wall of the slider 15 is slidably connected to the inside of the slide groove 14, one end of the connecting column 17 is slidably connected to a rack three 18, the inside of the rotating plate 11 is rotatably connected to a rotating column 21, the rack three 18 is meshed with the gear two 19, the side wall of the rack three 18 is slidably connected to the top of the fixed block 16, the outer wall of the rotating plate 11 is fixedly connected to a connecting plate 22, the side wall of the connecting plate 22 is fixedly connected to the side wall of the fixed block 16, and the side wall of the rotating plate 11 is fixedly connected to the connecting block 20.

[0027] Specifically, by precisely controlling the rotation of the rotating plate 11, it is ensured that the connecting plate 22 rotates in an orderly manner under the guidance of the rotating column 21, thereby realizing the adjustment of the relative position. During this process, the meshing action of the rack three 18 and the gear two 19 prompts the rack three 18 to slide inside the connecting column 17, thereby ensuring that the connecting plate 22 can maintain a stable state during rotation. In addition, the precise restriction of the slider 15 by the slide groove 14 further ensures that the rotating plate 11 can accurately change its relative position during the rotation process. Finally, through the precise engagement of the connecting block 20 with the interface, effective protection of the interface is achieved, thereby significantly improving the overall safety of the device, and also helping to extend the service life of the interface.

[0028] Working principle: By pulling the slide column 2 to move, the rack 2 6 moves with it. Since the two gears 1 7 and the rack 2 6 are meshed with each other, and the gear 1 7 is meshed with the rack 1 5, the gear 1 7 will rotate due to the movement of the rack 2 6. By cooperating with the rack 1 5, the support plate 8 drives the moving column 3 to move. As the rack 2 6 moves, the baffle 23 will limit the continued movement of the rack 2 6 and clamp the gear 1 7 so that it cannot rotate, thereby limiting the movement of the slide column 2 and the moving column 3. Finally, by pressing the clamping column 9, the position of the clamping column 9 is adjusted to determine the telescopic length, and the clamping column 9 is engaged with the positioning hole 10 to fix the moving column 3. , thereby completing the telescopic movement and improving the portability and flexibility of the temperature measuring device. By rotating the rotating plate 11, the connecting plate 22 changes its relative position through the rotation of the rotating column 21, and supports the rotating plate 11 when it moves. During this process, the rack three 18 and the gear two 19 engage with each other, so that the rack three 18 slides out from the inside of the connecting column 17, and maintains its stability when the connecting plate 22 rotates. Due to the restriction of the slide 15 by the slide groove 14, the relative position of the rotating plate 11 is changed when it rotates. Finally, the connecting block 20 is engaged with the interface to complete the protection of the interface, improve the safety of the device, and extend the service life of the interface.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
