Description

Technical Field

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

[0002] In order to ensure food safety, it is necessary to sample and test food. For sampling of frozen meat products, frozen food is relatively hard, so ordinary samplers are difficult to complete the sampling work.

[0003] Publication (Announcement) No.: CN216361692U, a rapid sampler for food testing, which drills holes in frozen meat food and then collects the debris left by the drilling. Although the above sampler can complete the sampling of frozen food, there is a possibility that the debris generated by the drilling will splash around and may be contaminated;

[0004] Publication (Announcement) No.: CN216926162U, a convenient frozen food sampling device, after the sample is drilled, it is transported inside the feed barrel by a spiral conveyor shaft, and finally collected into the sample collection container through the discharge port. Although the possibility of debris contamination is reduced, the feed barrel and the drill bit are contaminated by the sampling after each sampling, and need to be replaced as a whole or thoroughly disinfected before use, otherwise cross contamination is likely to occur.

[0005] In summary, this solution provides a rapid sampler for food testing, which can integrate a drill bit, a feed tube and a sampling bottle to achieve pollution-proof collection of drilled samples. Utility Model Content

[0006] The utility model aims at least to solve the problem in the prior art that when drilling holes for sampling frozen food, the sample is easily contaminated or the sampler is contaminated.

[0007] The present invention provides a rapid sampler for food testing, which is achieved by the following specific technical means: it includes a sampling controller and a drilling sampler spliced ​​with the sampling controller, the drilling sampler includes an outer cylinder docked with the shell of the sampling controller, a movable cylinder is slidably sleeved on the front end of the outer cylinder, a drill bit is rotatably penetrated in the outer cylinder, and the rear end of the drill bit is docked with a power shaft rotatably arranged on the sampling controller. When sampling, it is necessary to remove the cover first, and then press the front end of the movable cylinder on the frozen meat. As the drill bit is inserted, the movable cylinder will move backward along the outer cylinder to ensure that the movable cylinder is always covered at the drill hole, and the debris brought out by the drill hole is collected. After the sampling is completed, the drill bit is pulled out, and then the cover can be covered to store the sample.

[0008] Preferred technical solution 1: A clamping assembly is provided at the front end of the housing of the sampling controller, and a convex ring is sleeved on the rear end of the outer cylinder, and the clamping assembly clamps the convex ring from the circumferential side.

[0009] Preferred Technical Solution 2: A first spring is connected between the convex ring and the movable cylinder, and the first spring is slidably sleeved on the outer cylinder.

[0010] Preferred Technical Solution 3: A motor is installed inside the housing of the sampling controller, and the output shaft of the motor is fixedly connected to the power shaft to realize the electric control of the drill bit. Alternatively, the rear end of the power shaft extends out of the housing, and a crank is installed at the rear end of the power shaft to replace the motor.

[0011] Preferred Technical Solution 4: A handle portion is provided at the rear end of the housing. A battery electrically connected to the motor is installed in the handle portion, and a charging port connected to the battery is also provided in the handle portion.

[0012] Preferred Technical Solution 5: As an alternative to the clamping assembly, the rear end of the outer cylinder is engaged with the inner wall thread of the front end of the housing by means of an outer wall thread.

[0013] Adopting the above structure makes this solution have the following beneficial effects:

[0014] 1. The drilling sampler integrates functions such as drilling, preventing debris from splashing, collecting debris, and storing samples, effectively avoiding the problem that different tools are required for drilling, collecting debris, and storing frozen meat, which is likely to cause external contamination of the samples or cross-contamination between samples. At the same time, it also improves the convenience of sampling;

[0015] 2. The sample does not need to be transferred between multiple tools, improving the convenience of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0025] Example 1, please refer to Figure 1 and Figures 4 - 5 , a rapid sampler for food detection, including a sampling controller 1 and a drilling sampler 2 spliced and connected to the sampling controller 1. The drilling sampler 2 includes an outer cylinder 21 docked with the housing 11 of the sampling controller 1. A movable cylinder 22 is slidably sleeved at the front end of the outer cylinder 21. A drill bit 23 is rotatably penetrated through the outer cylinder 21. The rear end of the drill bit 23 is docked with a power shaft 12 rotatably arranged on the sampling controller 1. A convex block 231 fixed to the rear end of the drill bit 23 can be inserted into a card slot 121 opened on the front end face of the power shaft 12 to realize the docking of the drill bit 23 and the power shaft 12. In the initial state, the movable cylinder 22 is pulled to the front end of the outer cylinder 21. At this time, the drill bit 23 is completely received in the sampling cavity formed by the outer cylinder 21 and the movable cylinder 22. At this time, the front end opening of the movable cylinder 22 is covered with a sealing cover 24. When in use, first dock and fix the rear end of the outer cylinder 21 with the outer shell of the sampling controller 1, and at the same time dock the rear end of the drill bit 23 with the power shaft 12. When sampling, it is necessary to first remove the sealing cover 24, then press the front end opening of the movable cylinder 22 on the frozen meat, and then start the rotation of the power shaft 12 on the sampling controller 1 to drive the drill bit 23 to drill into the frozen meat. As the drill bit 23 extends, the movable cylinder 22 will move backward along the outer cylinder 21 to ensure that the movable cylinder 22 always covers the drilling position, collect the debris brought out by the drilling, and prevent scattering. After sampling, pull out the drill bit 23, then the sealing cover 24 can be covered, and the drilling sampler 2 can be separated from the sampling controller 1 for sample storage;

[0026] A first spring 25 is connected between the rear end of the outer cylinder 21 and the movable cylinder 22. The middle part of the first spring 25 is slidably sleeved on the outer cylinder 21, and the elastic force of the first spring 25 is used to push the movable cylinder 22 away from the sampling controller 1.

[0027] Example 2. On the basis of Example 1, please refer to Figure 1 and Figures 3 - 6 , a rapid sampler for food detection. A clamping assembly 16 is provided at the front end of the housing of the sampling controller 1. At the same time, a convex ring 211 is sleeved on the rear end of the outer cylinder 21. When the rear end of the outer cylinder 21 contacts the front end face of the housing, the clamping assembly 16 clamps the convex ring 211 from the circumferential side; the clamping assembly 16 includes a sleeve 161 rotatably installed in the housing. The power shaft 12 passes through the inner cavity of the sleeve 161 and is rotatably connected to the sleeve shaft. A control disk 162 is sleeved on the sleeve shaft. A plurality of arc-shaped protrusions 163 are fixed on the circumferential side of the control disk 162. A plurality of convex seats 111 are fixed on the circumferential side of the side wall of the housing. The number of the convex seats 111 is equal to the number of the arc-shaped protrusions 163 and their positions correspond one by one. A clamping member 164 is hingedly connected to each convex seat 111. A linkage rod 165 slidably penetrates through the side wall of the housing 11. The inner end of the linkage rod 165 contacts the side of the control disk 162. At the same time, the outer end of the linkage rod 165 contacts the rear end of the clamping member 164. The front end of the clamping member 164 extends to the front side of the housing, and a second spring 166 is connected between the clamping member 164 and the side wall of the housing at the front side of the convex seat 111. When the sleeve shaft drives the control disk 162 to rotate so that the arc-shaped protrusion 163 contacts the linkage rod 165, the linkage rod 165 will be pushed outwards, causing the clamping member 164 to swing, so that the front end of the clamping member 164 swings towards the direction of the power shaft 12 to press and fix the convex ring 211 on the front end face of the housing, realizing the docking and fixation between the outer cylinder 21 and the housing;

[0028] A control handle 167 is sleeved on the sleeve 161, and the end of the control handle 167 extends out from a window 112 opened on the housing for convenient control.
