Technical Field
[0001] This utility model belongs to the field of testing equipment, and specifically relates to a multifunctional food testing instrument with an easily replaceable testing head. Background Technology
[0002] Food testing instruments are specialized equipment used to detect various components and indicators in food, as well as to assess food quality, safety, and grade. Currently, when switching between different testing functions, such as from detecting pesticide residues to detecting microbial indicators, the lack of easily replaceable detection heads often necessitates replacing the entire instrument or re-adjusting and reinstalling the complex internal detection modules. This process is time-consuming and severely impacts testing efficiency. From the perspective of handling detection head malfunctions, the inability to easily replace the detection head requires a comprehensive overhaul of the entire instrument. Even a localized problem with the detection head can lead to prolonged downtime, delaying numerous testing tasks. When addressing diverse testing needs, the characteristics and testing requirements of different foods vary significantly. For example, the testing methods for liquid and solid foods differ. Instruments without easily replaceable detection heads cannot quickly adapt to different types of food, limiting their applicability. The conventional solution is to purchase multiple testing instruments with different functions, but this significantly increases costs and occupies considerable space. Therefore, a new structure is needed to solve these technical problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a multifunctional food testing instrument with an easily replaceable detection head, comprising: an adjustment component and an installation component. The adjustment component is installed on the upper surface of the base box 100 for adjusting the detection position. An installation component is installed on the surface of the adjustment component for replacing the detection head body. The adjustment component includes a fixing bracket 200 for fixing the adjustment slide rail 210. A sliding plate 220 is slidably installed on the front surface of the adjustment slide rail 210. The installation component includes an installation part for installing the detection head body.
[0023] Please see Figures 1 to 4 As the first embodiment of this utility model: a universal wheel 110 with a self-locking structure is installed at each of the four corners of the lower surface of the bottom box 100; a box door 120 is hinged to the front surface of the bottom box 100; and two fixing brackets 200 are symmetrically installed on the rear edge of the upper surface of the bottom box 100.
[0024] Adjustable slide rails 210 are installed on the upper edge of the front surface of the two fixed brackets 200. The front surface of the adjustable slide rails 210 is damped and slidably connected to the center of the rear surface of the slide plate 220. A slider 230 is damped and slidably installed on the front surface of the slide plate 220.
[0025] During use, the user first adjusts the detection position using the adjustment component. This adjustment involves using the slide rail 210 to adjust the left and right positions of the front surface slide plate 220 (the slide rail 210 is existing technology, and its specific structure and connection principle are not detailed here). After adjusting the left and right positions of the slide plate 220, the user can then adjust the height of the detection position using the slider 230 to further adjust the position parameters. Once all operations are complete, the user can then use the detection head to detect the food to be tested. During the detection process, if the detection head position is fixed, improper sample placement or instrument operation errors may cause the detection head to collide with the sample or other parts of the instrument, resulting in damage. The adjustment component allows for fine-tuning of the detection head position before detection, ensuring a safe distance between the detection head and the sample and other parts, preventing collisions, and extending the lifespan of the detection instrument and the sample.
[0026] Please see Figures 1 to 4As a second embodiment of the present utility model: the mounting component includes a mounting block 300, a mounting post 310, a threaded post 330 and an electrical post 340. The mounting block 300 is fixed on the front surface of the slider 230. The mounting post 310 is installed at the center of the lower surface of the mounting block 300. A gasket 320 is glued to the end of the mounting post 310 away from the mounting block 300.
[0027] A threaded post 330 is integrally formed at the center of the side surface of the mounting post 310 away from the mounting block 300, and an electrical post 340 is integrally formed at the end of the threaded post 330 away from the mounting post 310.
[0028] The diameter of the electrical post 340 is smaller than the diameter of the threaded post 330. The detection head body includes a fixed post 350 and a detection body 360. The detection body 360 is integrally formed at the lower end of the fixed post 350.
[0029] A gasket 370 is installed on the upper surface of the fixed post 350, and a threaded groove 351 is installed at the center of the upper surface of the fixed post 350. An electrical contact for electrical connection with the electrical post 340 is installed at the bottom inside the threaded groove 351.
[0030] In use, when a user tests food using the first embodiment, the user can first adjust the slider 230 to its highest position for easier operation. After adjustment, the user can hold the detection body 360 at the lower end of the fixed post 350 and rotate the detection body 360 to move the fixed post 350 away from the threaded post 330. Once the fixed post 350 is away from the threaded post 330, it is no longer restrained by the threaded post 330, and the user can remove the detection body 360 for replacement. (Multiple detection bodies 360 are provided, and each detection body 360 is used for different testing items. The detection body 360 is a prior art technology.) The specific structure and detection principle of the device will not be elaborated here. When replacing it, the user only needs to reverse the above steps. Since the electrical contacts inside the fixed column 350 are electrically connected to the electrical column 340, the user does not need to make additional circuit connections or use tools, making it convenient for the user to operate. The setting of the mounting part makes the replacement of the detection head simple and easy. The staff does not need to use complicated tools or perform tedious disassembly steps. They only need to connect or separate the detection head from the mounting part to complete the replacement process. The detection function can be switched in a short time, improving the efficiency of the detection work.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
