Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a food sulfur dioxide analyzer with positioning function. Background Technology

[0002] The rapid sulfur dioxide analyzer for food is mainly used for the rapid determination of sulfur dioxide content in sugars, alcoholic beverages, and various dried fruits. It features a large-screen LCD Chinese display and intelligent control functions, and the supporting equipment includes an ultrasonic extractor, electronic scale, and other tools.

[0003] In existing technologies, when using a food sulfur dioxide analyzer, the support legs contact the table. To ensure stability, suction cups are usually added to the support legs for positioning. However, this method has the following drawbacks in actual use: when the suction cups are positioned, they are easily affected by external touches and fatigue deformation, which can cause them to detach from the table, thus reducing the stability of the analyzer. If the analyzer is bumped or struck during this process, it can cause the liquid surface in the cuvette to tilt, the solution to splash out, or an increase in bubbles, affecting the accuracy of the test. Utility Model Content

[0004] Therefore, it is necessary to provide a food sulfur dioxide analyzer with positioning function to address the problem that the suction cup is easily detached from the table due to external contact and fatigue deformation during positioning.

[0005] A food sulfur dioxide analyzer with positioning function includes a main body and a set of legs mounted on its outer side, with a suction cup at one end of each leg; it also includes an auxiliary mechanism, which is a set of auxiliary mechanisms located outside the suction cup and used to limit and protect the suction cup, reducing its detachment from the tabletop after deformation; wherein, the auxiliary mechanism includes a sleeve and a pressure ring, the sleeve is fixedly fitted to the outer side of the legs, the pressure ring is located inside the sleeve and can move vertically, and the suction cup is located below the pressure ring.

[0006] In one embodiment, the auxiliary mechanism further includes a retaining ring, which is fitted onto the outside of the suction cup to shield and protect the suction cup, reducing the occurrence of external impacts and debris colliding with the suction cup, thus preventing the suction cup from separating from the table.

[0007] In one embodiment, a lead screw is rotatably connected to the sleeve, and a sliding ring is installed on the outside of the pressure ring. One end of the lead screw passes through and is threaded to the outside of the sliding ring, driving the pressure ring to move vertically.

[0008] In one embodiment, a set of uprights is provided on the outer side of the retaining ring, and a set of ear plates is provided on the outer side of the sleeve, with one end of the uprights passing through and slidably connected to the outer side of the ear plates.

[0009] In one embodiment, a spring is fitted on the outer side of the upright, with one end of the spring installed on the outer side of the ear plate and the other end of the spring installed on the outer side of the upright, so as to apply slight pressure to the retaining ring and ensure the protective effect.

[0010] In one embodiment, the retaining ring is on the same horizontal plane as one side of the suction cup, and the inner diameter of the retaining ring is larger than the diameter of the suction cup after it is deformed by adsorption onto the table.

[0011] In one embodiment, the side of the retaining ring away from the sleeve is provided with anti-slip texture to improve positioning stability.

[0012] In one embodiment, a limiting rod is provided inside the sleeve, one end of which passes through and is slidably connected to the outside of the sliding ring to ensure the stability of the movement direction of the pressure ring.

[0013] Beneficial effects 1. By setting a pressure ring, when the suction cup is adsorbed and docked with the table, the sliding ring is driven by a lead screw to move, so that the pressure ring applies pressure to the suction cup, reducing the phenomenon of the suction cup detaching from the table due to fatigue deformation during use, thereby ensuring the positioning effect and the accuracy of the detection operation. 2. By setting a retaining ring, the accidental contact between the suction cup and the tabletop is reduced when the suction cup is adsorbed and docked, thereby reducing the occurrence of suction cup detachment, improving the positioning effect of the measuring instrument on the tabletop, reducing the occurrence of liquid tilting in the cuvette, solution splashing or increased bubbles, and improving the accuracy of the detection operation.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] The following is combined with Figures 1-5 This invention describes a food sulfur dioxide analyzer with positioning function.

[0019] In one embodiment, a food sulfur dioxide analyzer with positioning function includes an analyzer body 100 and a set of support legs 200 mounted on its outer side, with a suction cup 210 provided at one end of each support leg 200; it also includes an auxiliary mechanism 300, which is a set of auxiliary mechanisms. The auxiliary mechanism 300 is located outside the suction cup 210 and is used to limit and protect the suction cup 210, reducing its detachment from the tabletop after deformation; wherein, the auxiliary mechanism 300 includes a sleeve 310 and a pressure ring 320. The sleeve 310 is fixedly sleeved on the outer side of the support leg 200, the pressure ring 320 is inside the sleeve 310 and can move vertically, and the suction cup 210 is located below the pressure ring 320.

[0020] like Figure 2 , Figure 3 and Figure 4 As shown, the auxiliary mechanism 300 also includes a retaining ring 330, which is sleeved on the outside of the suction cup 210.

[0021] In this embodiment, the suction cup 210 on the support leg 200 is used to adsorb and dock with the table. After the suction cup 210 moves into position, the pressure ring 320 inside the sleeve 310 is driven downward. The pressure ring 320 is used to press and limit the outer side of the suction cup 210, reducing the possibility of accidental deformation. After the suction cup 210 is adsorbed into position, the retaining ring 330 will be on the outer side of the suction cup 210, which can reduce the impact of external bumps on the suction cup 210 during the detection operation, thereby ensuring the stable docking of the suction cup 210 with the table, improving the stability of the main body 100 of the measuring instrument, reducing the shaking phenomenon after accidental bumps, and thus reducing the occurrence of liquid tilting and shaking and liquid splashing in the cuvette during the detection process.

[0022] It should be noted that the model of the measuring instrument body 100 in this application is TY-R12T; The support leg 200 of this application can also be an adjustable support leg commonly used in the market. Without affecting the suction cup 210's adsorption and positioning, it can be selected according to the actual use environment and needs. The specifications and dimensions of the suction cup 210 and the pressure ring 320 can be selected according to actual needs. After the suction cup 210 adsorbs and deforms, the pressure ring 320 descends and can contact the outside of the suction cup 210.

[0023] like Figure 4 As shown, a lead screw 311 is rotatably connected to the sleeve 310, and a sliding ring 321 is installed on the outside of the pressure ring 320. One end of the lead screw 311 passes through and is threaded to the outside of the sliding ring 321.

[0024] The rotation of the lead screw 311 can drive the sliding ring 321 to move, thereby causing the pressure ring 320 to limit the suction cup 210; It should be noted that a knob is installed on the end of the lead screw 311 located outside the sleeve 310, and the knob is far from the axis of the measuring instrument body 100, which makes it easier for users to improve the operating efficiency of the pressure ring 320.

[0025] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a set of uprights 331 are provided on the outer side of the retaining ring 330, and a set of ear plates are provided on the outer side of the sleeve 310. One end of the uprights 331 passes through and is slidably connected to the outer side of the ear plates.

[0026] The upright rod 331, in conjunction with the ear plate, limits the movement direction of the retaining ring 330, reducing the deviation of the retaining ring 330 and ensuring its stable vertical movement.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, a spring 332 is fitted on the outer side of the upright 331. One end of the spring 332 is installed on the outer side of the ear plate, and the other end of the spring 332 is installed on the outer side of the upright 331.

[0028] With the spring 332, when the suction cup 210 is attached to the table, the retaining ring 330 will be in contact with the table. At this time, the spring 332 is in a slightly compressed state, which can ensure the stability of the retaining ring 330 and provide real-time protection for the suction cup 210. It should be noted that the spring 332 in this application has four coils. The specific elastic coefficient and number of coils can be selected according to actual usage requirements. It is only necessary to achieve a slight reset effect, reduce excessive force on the adsorption point, and ensure the adsorption stability of the suction cup 210. One end of the upright 331 has an integrally formed disc, which is connected to the spring 332 to achieve stable support for the spring 332.

[0029] like Figure 2 and Figure 4 As shown, the retaining ring 330 and one side of the suction cup 210 are on the same horizontal plane, so that when the suction cup 210 contacts the table, the retaining ring 330 contacts the table simultaneously. After the suction cup 210 deforms and adheres, the retaining ring 330 can continue to block the suction cup 210. The inner diameter of the retaining ring 330 is larger than the diameter of the suction cup 210 after it deforms and adheres to the table.

[0030] This ensures that after the suction cup 210 is deformed by adsorption, it will not come into contact with the retaining ring 330, thereby reducing the deformation and warping of the suction cup 210 and ensuring stable adsorption.

[0031] like Figure 5 As shown, the retaining ring 330 has anti-slip texture on the side away from the sleeve 310.

[0032] The anti-slip texture reduces the displacement after excessive accidental bumps, and the suction cup 210 enhances the overall positioning strength.

[0033] like Figure 4 As shown, a limiting rod is provided inside the sleeve 310, and one end of the limiting rod passes through and slides to the outside of the sliding ring 321.

[0034] The use of a limit rod can reduce the accidental displacement of the sliding ring 321 during movement and ensure the stability of the movement of the sliding ring 321 and the pressure ring 320.

[0035] Working principle: Place the main body 100 of the measuring instrument in a suitable position on the table, and then attach the suction cup 210 to the table. At this time, the retaining ring 330 is outside the suction cup 210 for protection. Then, the user can rotate the knob to make the screw 311 drive the pressure ring 320 to move downward, press and limit the suction cup 210, and reduce the accidental deformation of the suction cup 210. After that, the sulfur dioxide measurement of food can be carried out. When the measuring instrument body 100 is finished and needs to be transported, the user can flip the knob, and the lead screw 311 will reset the drive pressure ring 320. Then the user can slightly move the suction cup 210 to detach it from the table, and then the measuring instrument body 100 can be directly moved away for transport.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
