Description

Technical Field

[0001] The utility model relates to the technical field of food detection equipment, in particular to a food sampler. Background Art

[0002] In order to ensure food safety, food safety supervision departments will conduct random sampling and testing on various foods from time to time. Food testing requires sampling of multiple ingredients. When sampling food, existing food samplers need to extend the samplers into different food containers for sampling. The length of the existing section samplers cannot be adjusted, which makes it very inconvenient to sample food from deep inside. In addition, the amount of sampling and testing required for different foods is also different. The existing samplers can only perform repeated sampling of small amounts multiple times, which makes the sampling process very cumbersome. Therefore, a food sampler is designed to solve the above problems. Utility Model Content

[0003] In view of the shortcomings of existing food testing equipment, the purpose of the present invention is to provide a food sampler with the advantages of variable sampling capacity and adjustable sampler length.

[0004] To achieve the above-mentioned purpose, the present invention adopts a technical solution as follows: a food sampler, comprising a positioning rod, a locking assembly, a telescopic arm, a sampling box and a variable assembly, wherein the positioning rod is symmetrically hinged with the other positioning rod, one end of the positioning rod is provided with an arc-shaped grip for easy handholding, the other end of the positioning rod is provided with a slide groove, the telescopic arm is slidably connected to one end of the positioning rod through the slide groove, the telescopic arm and the sliding end of the positioning rod are provided with a locking assembly, the outer side of the positioning rod is provided with a plurality of slots, the locking assembly is clamped in the slot to position the telescopic arm, the bottom ends of the telescopic arms on both sides are provided with mutually symmetrical sampling boxes, and the sampling box is provided with a variable assembly with adjustable clamping capacity;

[0005] Preferably, the locking assembly comprises a locking rod and a spring, wherein the locking rod is hinged to the telescopic arm and the sliding end of the positioning rod, one end of the locking rod comprises a bayonet, and the other end of the locking rod comprises a positioning groove for installing a spring, and the spring forces the bayonet to engage with the outer slot of the positioning rod for positioning;

[0006] Preferably, the variable assembly comprises an adjustment plate and an adjustment screw, the adjustment plate being slidably connected in the sampling box, the adjustment screw penetrating the bottom end surface of the sampling box and engaging therewith, the adjustment screw extending into the sampling box and being rotatably connected to the adjustment plate;

[0007] Preferably, the bottom of the telescopic arm on one side is further provided with a positioning pin, and the bottom of the telescopic arm on the other side is provided with a positioning hole corresponding to the position of the positioning pin; when adjusting the extension length of the telescopic arm, the hinged positioning rods on both sides are closed so that the positioning pin at the bottom of the telescopic arm is inserted into the positioning hole of the telescopic arm on the other side, so that the extension distance of the telescopic arm can be adjusted synchronously to prevent leakage caused by misalignment of the sampling boxes on both sides;

[0008] The beneficial effects of the present invention are: 1. By pressing the locking rods on the telescopic arms on both sides, the pin on one side of the locking rod is no longer stuck in the outer slot of the positioning rod, so that the extension distance of the telescopic rod can be adjusted to drive the sampling box to move to adapt to sampling at different depths; 2. By rotating the adjusting screw at the bottom end of the sampling box, the adjusting screw simultaneously drives the adjusting plate to move in the sampling box, thereby changing the distance between the adjusting plate and the bottom end surface of the sampling box, thereby realizing changing the capacity of the sampling box to clamp food.
