Description

Technical Field

[0001] This utility model relates to the field of food safety testing, and in particular to a portable spectral analysis device for food safety. Background Technology

[0002] As public awareness of food safety increases, traditional testing methods are increasingly failing to meet demands in terms of efficiency and accuracy. Spectroscopic analysis technology has emerged as a solution in the field of food safety. On the one hand, the rapid development of the food industry, including the emergence of numerous new food products and the globalization of the food supply chain, presents new challenges to food safety testing, such as the need for rapid and accurate detection of various components, contaminants, and additives in food. On the other hand, spectroscopic analysis devices utilize the principle that different substances possess unique spectral characteristics. By analyzing the light emitted or absorbed by food samples, they can detect whether the nutritional components in food meet standards and whether harmful chemicals such as pesticide residues, heavy metals, and microbial toxins are present, thereby ensuring food safety.

[0003] Currently available food safety spectroscopic analysis devices are quite bulky, making them inconvenient to store and carry, and hindering daily food safety testing. However, most office workers now choose to eat near their workplace, making a food safety spectroscopic analysis device that is easy to store and carry particularly important.

[0004] Therefore, there is a need to design a portable spectral analysis device for food safety that is easy to store and carry. Utility Model Content

[0005] To overcome the shortcomings of food safety spectral analysis devices, which are generally large in size and inconvenient to store and carry, the technical problem to be solved is to provide a portable spectral analysis device for food safety that is easy to store and carry.

[0006] The technical solution is as follows: A portable spectral analysis device for food safety includes a main unit, a spectral analysis head, a display screen, and a rotating handle. The spectral analysis head is connected to the left side of the main unit, the display screen is connected to the right side of the main unit, and the rotating handle is rotatably connected to the lower side of the main unit. The rotating handle can be rotated and retracted to be embedded in the main unit.

[0007] Preferably, the device also includes a connecting frame, a protective cover, a first torsion spring, a buffer frame, and a telescopic spring. The lower side of the spectral analysis head and the display screen are both connected to the connecting frame. The upper left side of the connecting frame is rotatably connected to the protective cover. The protective cover and the front and rear sides of the adjacent connecting frame are both connected to the first torsion spring. The sides of the protective covers that are close to each other are slidably connected to the buffer frame. Multiple telescopic springs are connected between the buffer frame and the adjacent protective cover.

[0008] Preferably, it also includes a rotating frame, a connecting rod, and a limiting rod. The rotating frame is rotatably connected to the upper side of the main unit, and the limiting rod is slidably connected to the upper side of the spectral analysis head and the display screen. The limiting rod is engaged with the adjacent protective cover, and the connecting rod is rotatably connected to both the limiting rod and the rotating frame.

[0009] Preferably, a protective cover is also included, with the protective cover connected between the upper side of the main unit, the spectral analysis head and the display screen, and the protective cover being rotatably connected to the rotating frame.

[0010] Preferably, it also includes a knob, which is connected to the upper side of the rotating frame.

[0011] Preferably, a second torsion spring is also included, and the main unit and the rotating frame are connected by the second torsion spring.

[0012] The beneficial effects of this utility model are as follows: 1. When using this utility model, first rotate the handle downwards to make it easier for people to grip and control the device. After use, rotate the handle back to its original position so that the handle is embedded in the main unit, making it easy to store and carry.

[0013] 2. This utility model can protect the spectral analysis head and display screen by rotating the protective cover upwards to reset it. At the same time, the buffer frame will first contact the spectral analysis head and display screen, and the telescopic spring will deform to buffer the impact, thereby avoiding damage to the spectral analysis head and display screen due to excessive force.

[0014] 3. This utility model can rotate the rotating frame by rotating the knob, and then move the limiting rod to the side that is closer to each other through the connecting rod. At the same time, it controls the limiting rod to disengage from the protective cover, so that the protective cover can be rotated downward to open. The operation is simple and convenient.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] A portable spectral analysis device for food safety, such as Figure 1-5 As shown, the device includes a main unit 1, a spectral analysis head 2, a display screen 3, a rotating handle 4, a connecting frame 5, a protective cover 6, a first torsion spring 7, a buffer frame 8, a telescopic spring 9, a protective cover 10, a knob 11, a rotating frame 12, a second torsion spring 13, a connecting rod 14, and a limiting rod 15. The spectral analysis head 2 is connected to the left side of the main unit 1, and the display screen 3 is connected to the right side of the main unit 1. The rotating handle 4 is rotatably connected to the lower side of the main unit 1. The rotating handle 4 can be rotated and retracted to embed into the main unit 1. The lower side of both the spectral analysis head 2 and the display screen 3 is connected to the connecting frame 5. The upper left side of the connecting frame 5 is rotatably connected to the protective cover 6. The first torsion spring is connected between the protective cover 6 and the front and rear sides of the adjacent connecting frame 5. 7. Buffer frames 8 are slidably connected to the adjacent sides of the protective covers 6. Multiple telescopic springs 9 are connected between the buffer frames 8 and the adjacent protective covers 6. A rotating frame 12 is rotatably connected to the upper side of the main unit 1. Limiting rods 15 are slidably connected to the upper sides of the spectral analysis head 2 and the display screen 3. The limiting rods 15 are respectively engaged with the adjacent protective covers 6. A connecting rod 14 is rotatably connected between the limiting rods 15 and the rotating frame 12. A protective cover 10 is connected between the upper sides of the main unit 1, the spectral analysis head 2, and the display screen 3. The protective cover 10 is rotatably connected to the rotating frame 12. A knob 11 is connected to the upper side of the rotating frame 12. A second torsion spring 13 is connected between the main unit 1 and the rotating frame 12.

[0023] Initially, the first torsion spring 7 is in a deformed state. In use, first rotate the rotating handle 4 downwards and remove it. Then, rotate the knob 11 clockwise, causing the rotating frame 12 to rotate clockwise. The second torsion spring 13 deforms, and the rotating frame 12, through the connecting rod 14, moves the limiting rod 15 towards one side. At this point, the limiting rod 15 disengages from the protective cover 6. The first torsion spring 7 then returns to its original position, causing the protective cover 6 to rotate downwards and open, thus no longer obstructing the spectral analyzer head 2 and the display screen 3. The device can then be controlled to perform spectral analysis for food safety. After use, the protective cover... When the cover 6 is rotated upwards to reset, the buffer frame 8 will first contact the spectrometer head 2 and the display screen 3. At this time, the telescopic spring 9 will deform to buffer the movement, thereby avoiding excessive force that could damage the spectrometer head 2 and the display screen 3. After the protective cover 6 is rotated upwards to reset, the control knob 11 is no longer controlled. At this time, the second torsion spring 13 returns to its original position, causing the rotating frame 12 to rotate in the opposite direction. This causes the limiting rod 15 to move to the opposite side via the connecting rod 14. At this time, the limiting rod 15 engages with the protective cover 6 to fix the protective cover 6. Then, the handle is rotated to reset, so that the handle is embedded in the main unit 1, making it convenient for storage and carrying.

[0024] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
