[0002] In food production, acidity meters are commonly used to determine the acidity of food samples. Currently, in commonly used acidity meters, the connecting rod for the pH probe is always positioned upright on one side of the meter body, with the pH probe always clipped to the end of the rod. This structure occupies a large amount of space, and when not in use, it is unhygienic to be directly exposed to the air, and is also easily damaged by accidental contact, especially the pH probe. To solve this problem, a structure has been developed that uses a flip-top box to house the entire acidity meter, with the connecting rod fixed inside the box and retractable, allowing the acidity meter to be stored away when not in use. However, this structure still occupies a large amount of space, requiring the lid to be flipped open for use, and the various storage compartments are not easy to clean, and the connecting rod is not easy to replace.

[0026] As shown in the figure, an acidity meter includes a housing 1. A push-pull support box 2 is inserted into one side of the housing 1, and the support box 2 has an opening on its upper side. An inverted L-shaped support rod 3 is inserted upward from the bottom of the support box 2 and can be stored inside the support box 2. A pH probe 4 is vertically inserted into the end of the support rod 3, and a storage groove 12 is provided on the upper side of the housing 1, in which the pH probe 4 can be placed. In this embodiment, the support box 2 that can be stored inside the housing 1 is provided on the housing 1, and the support rod 3 that can be detached is provided on the support box 2. When needed, the support rod 3 is installed in the support box 2, and the pH probe 4 is snapped into the end of the support rod 3 for testing. When not in use, the pH probe 4 is removed and placed in the storage groove 12 for storage, the support rod 3 is removed and placed in the support box 2 for storage, and finally the support box 2 is pushed into the housing 1. Of course, in this embodiment, the electronic components required for the acidity measuring instrument are installed inside the measuring instrument housing 1 to complete the acidity measurement. This is a conventional technical means that can be mastered by those skilled in the art, and the innovation of this application is not in this respect. Therefore, it will not be described in detail here.

[0027] The base plate of the support box 2 has mounting holes. The bottom of the vertical section 31 of the support rod 3 has mounting posts 35, and the bottom of the vertical section 31 of the support rod 3 has limiting bosses 36 that are horizontally arranged outward around the vertical section 31. The mounting posts 35 are inserted into the mounting holes, and the limiting bosses 36 overlap the upper side of the base plate of the support box 2. In this embodiment, the vertical section 31 of the support rod 3, the limiting bosses 36, and the mounting posts 35 are integrally formed.

[0028] A ring magnet 7 is fixedly connected to the mounting hole, and a stainless steel block is embedded and fixed at the bottom of the limiting boss 36. When the mounting post 35 of the support rod 3 is inserted into the magnet 7, the stainless steel block and the magnet 7 are magnetically attracted together. In this embodiment, an annular limiting groove is provided at the bottom of the limiting boss 36, and the stainless steel block is embedded and fixed in the limiting groove, with the lower surface of the stainless steel block flush with the lower surface of the limiting boss 36. In this embodiment, when the support rod 3 is vertically inserted into the magnet 7, the stainless steel block abuts against the upper side of the bottom plate of the bearing box 2 and is magnetically attracted together with the magnet 7, ensuring that the support rod 3 will not tilt and detach from the mounting hole.

[0029] The horizontal section 32 of the support rod 3 is connected to the top of the vertical section 31 by bolt and nut pair 6. When the support rod 3 needs to be stored in the bearing box 2, simply loosen the bolt and nut pair 6, merge the horizontal section 32 and the vertical section 31 of the support rod 3 together, remove the support rod 3 and place it in the bearing box 2.

[0030] The horizontal section 32 of the support rod 3 has an integrally formed positioning block 33 at its end. The positioning block 33 has multiple evenly distributed arc-shaped through slots 34 with openings on its sidewalls. The upper circumferentially outer part of the PH probe 4 has an overlapping block 42 that allows for longitudinal position adjustment. The upper part of the PH probe 4 is engaged in one of the arc-shaped through slots 34, and the overlapping block 42 overlaps the upper side of the positioning block 33. In this embodiment, the horizontal position of the PH probe 4 is adjusted by adjusting the position of the carrier box 2, and the vertical position of the PH probe 4 is adjusted by adjusting the position of the overlapping block 42.

[0031] The junction box 41 on the upper part of the PH probe 4 has an external thread on the outside, and the lap block 42 is screwed onto the junction box 41 of the PH probe 4.

[0032] A handle 21 is fixed to the outer wall of the carrier box 2 to facilitate pulling out the carrier box 2.

[0033] An inverted U-shaped receiving groove 11 is provided on one side of the measuring instrument housing 1 corresponding to the carrier box 2, and support bars 13 are provided inward on both sides of the bottom opening of the receiving groove 11. The carrier box 2 is located on the upper side of the two support bars 13. A support block 22 is provided at the bottom of the outer wall of the carrier box 2, and the support block 22 is located between the two support bars 13, so that the carrier box 2 can be completely pushed into the receiving groove 11. After the carrier box 2 is pulled out, the support block 22 supports the carrier box 2 to prevent the outer end of the carrier box 2 from being suspended.

[0034] The measuring instrument housing 1 has pads 14 at the four corners of the bottom, and the bottom side of the pads 14 is flush with the bottom side of the support block 22.

[0035] A protective cover 5 is hinged to the opening of the storage slot 12. A U-shaped groove 15 communicating with the storage slot 12 is provided at the rear end of the measuring instrument housing 1. When the pH probe 4 is placed in the storage slot 12, the power cord of the pH probe 4 passes through the U-shaped groove 15. In this embodiment, one end of the protective cover 5 away from the U-shaped groove 15 is hinged to the corresponding edge of the storage slot 12, and the other end is a free end. A sealing strip is provided around the protective cover 5 to ensure that the protective cover 5 can be positioned by friction when it is fastened in the storage slot 12, preventing the protective cover 5 from being accidentally flipped over. In addition, the U-shaped groove 15 provides a power cord connection point for the pH probe 4 to be placed in the storage slot 12, and also allows the operator to flip the protective cover 5 upward through the U-shaped groove 15.

[0036] The working process of this embodiment is as follows:

[0037] In use, pull the carrier box 2 out of the receiving groove 11. Adjust the degree of pull-out of the carrier box 2 according to the placement position of the solution to be tested. Then take out the support rod 3 and adjust the vertical section 31 and the horizontal section 32 to be vertical. Tighten the bolt and nut pair 6 and insert the vertical section 31 into the mounting hole so that the magnet 7 and the stainless steel block are magnetically attracted together, further enhancing the installation stability of the support rod 3. Then take out the pH probe 4 from the receiving groove 12 and adjust the position of the overlapping block 42 on the junction box 41 according to the page position of the solution to be tested. Then insert the pH probe 4 into the arc-shaped through groove 34 and make the overlapping block 42 overlap the upper side of the positioning block 33 for further limiting, so as to prevent the pH probe 4 from accidentally falling and damaging the container of the solution to be tested. Finally, turn on the power to operate.

[0038] After use, insert the pH probe 4 into the storage slot 12 and cover it with the protective cover 5. Then, fold up the support rod 3 and place it in the carrier box 2. Finally, push the carrier box 2 into the receiving slot 11.

[0039] 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.
