Technical Field

[0001] The utility model relates to the technical field of physical and chemical inspection, in particular to a titration device for food physical and chemical inspection. Background Technique

[0002] Titration analysis is an experimental method that indicates the titration end point according to the color change of the indicator, and then visually observes the volume of the standard solution consumed and calculates the analysis result. In the prior art, titration analysis needs to be realized by means of a special titration device, so a titration device for food physical and chemical inspection is required.

[0003] However, the existing titration devices have the following disadvantages:

During use, due to different experiments to be operated, the required heights of the devices are different, while the height of the traditional titration device is fixed and difficult to adjust, resulting in a more troublesome problem when using the device.

[0005] (2) For the existing titration devices, the function of improving the applicability of the device is weak. During use, since the position of the dropper of the traditional titration device is difficult to adjust, when different personnel use the device, they need to get close to the dropper, which is very troublesome, resulting in limitations of the device and being not conducive to use.

[0008] Optionally, a clamping groove is opened on the inner side wall of the fixed frame, and the clamping block is connected with the clamping groove. When the clamping block is clamped into the clamping groove, the clamping groove limits the clamping block.

[0009] Optionally, a sliding groove is opened on the inner side wall of the fixed frame, and the sliding block is connected with the sliding groove. When the lifting rod slides inside the fixed frame, it will drive the sliding block to slide inside the sliding groove, and the sliding groove limits the sliding block.

[0010] Optionally, a fixing ring is rotatably connected to the bottom of the surface of the fixing frame, and a base is fixedly connected to the bottom of the fixing ring. The setting of the base can fix the fixing ring, and the base supports the device.

[0011] Optionally, a circular slot is provided on the side surface of the limiting frame, and the connecting block is connected to the circular slot. When the connecting block is inserted into the circular slot, the circular slot limits the connecting block to fix the connecting block.
