Description

A liquid food sampling device to prevent sample contamination Technical Field

[0001] This utility model relates to the field of extraction devices, and more specifically, to a liquid food detection extraction device that prevents sample contamination. Background Technology

[0002] Food inspection encompasses a wide range of areas, including analysis of food nutritional components, analysis of contaminants in food, analysis of food auxiliary materials and food additives, and sensory evaluation of food. Inspections of food quality include tests on the characteristics, physicochemical indicators, and other hygiene indicators of the outer packaging, inner packaging, labeling, markings, and the appearance of the product itself. National food safety supervision departments conduct random sampling inspections of food circulating in the market on an irregular basis.

[0003] A search revealed that Chinese Patent Publication No. CN215448621U discloses a "Portable Sampling Device for Liquid Food Detection," which includes a liquid extraction cylinder with a liquid extraction tube at the bottom, a piston inside the cylinder, a pull rod at the top of the piston, through grooves on both sides inside the piston, a mounting bracket on one side of the inner wall of the through grooves, an outer sleeve on one side of the mounting bracket, and a spring inside the outer sleeve. This invention, through the cooperation of the spring, through grooves, mounting bracket, outer sleeve, inner sleeve, and retaining beads, can automatically extract purification liquid from the storage tank A to clean the cavity at the top of the piston when extracting samples for storage, preventing the previous sample from contaminating subsequent samples. Simultaneously, when extracting the next sample, it can automatically discharge the cleaning liquid into the storage tank B for storage, eliminating the need for further extraction of cleaning liquid and thus shortening the sample collection time. However, it still has the following drawbacks:

[0004] (1) The length of the tube in the existing extraction device cannot be adjusted. The liquid level in the bottle of the liquid food to be extracted is different. When the liquid level is lower than the length of the tube, the tube cannot reach below the liquid surface and extraction cannot be achieved, which affects the effectiveness of the extraction device.

[0005] (2) Existing extraction devices only have anti-fall structures and cannot be directly fixed to the bottle being extracted. Therefore, it is necessary to maintain the stability between the extraction device and the bottle during extraction, which affects the stability of the extraction device.

[0006] Therefore, we have made improvements to this and proposed a liquid food detection extraction device that prevents sample contamination. Summary of the Invention

[0007] The purpose of this invention is to address the problems that existing extraction devices are not suitable for liquids with different liquid levels and lack stability during use.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A liquid food testing extraction device that prevents sample contamination, in order to improve the above-mentioned problems.

[0010] The present invention is as follows:

[0011] Includes a sleeve, wherein a snap-fit ​​assembly is provided inside the sleeve, and outer plates are provided on both sides of the sleeve, with clamping assemblies provided on the outer sides of the outer plates;

[0012] The buckle assembly includes an inner tube that can be movably disposed inside the sleeve, an insertion tube that is connected to the lower end of the inner tube, and a pull tube that can be retracted and disposed inside the upper side of the insertion tube;

[0013] The clamping assembly includes a telescopic groove inside the outer plate, a telescopic plate movably disposed inside the telescopic groove, and a clamping ring disposed at the lower end of the side of the telescopic plate away from the sleeve.

[0014] As a preferred technical solution of this utility model, an inner groove is provided inside the sleeve on the right side of the inner tube, and a first bevel gear is provided inside the upper end of the inner groove. A knob is connected to the upper end of the first bevel gear.

[0015] As a preferred technical solution of this utility model, the inner wall of the inner groove near the inner tube is provided with a second bevel gear that cooperates with the first bevel gear.

[0016] As a preferred technical solution of this utility model, the inner groove is provided with a slot on the outer side near the inner tube, a screw is provided inside the slot, and a clamping plate is fitted on the outer wall of the screw.

[0017] As a preferred technical solution of this utility model, a limiting groove is provided on the upper side of the slot, and a limiting plate that cooperates with the limiting groove is provided on the upper side of the card plate.

[0018] As a preferred technical solution of this utility model, the side wall of the telescopic groove is provided with a side groove, and the side wall of the telescopic plate is provided with a side plate that cooperates with the side groove.

[0019] As a preferred technical solution of this utility model, a telescopic rod is connected to the side wall of the side plate, and a spring is fitted onto the outer wall of the telescopic rod.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In the solution of this utility model:

[0022] 1. By setting up a suction tube, a first bevel gear, a second bevel gear, a screw, and a clamping plate, when it is necessary to adjust the height of the insertion tube, the inner tube is pulled up and down to move it within the tube sleeve. After adjustment, turning the knob drives the first bevel gear connected to it to rotate, which in turn drives the second bevel gear connected to it to rotate, which in turn drives the screw connected to it to rotate. The engagement causes the clamping plate to slide within the slot. With the limiting plate embedded in the limiting slot, the clamping plate slides stably towards the inner tube. The surface of the clamping plate, through the frosted material, clamps the inner tube and positions it inside the tube sleeve, thereby achieving rapid adjustment of the insertion height of the insertion tube into the liquid level. By pulling the suction tube upward, the liquid can be drawn into the insertion tube through the insertion tube, achieving efficient use.

[0023] 2. By setting up a telescopic plate, clamping rings, side plates, telescopic rods, and springs, when it is necessary to install the extraction device on the upper side of the bottle to be extracted, pull the clamping rings outwards on both sides to move the telescopic plate in and out of the telescopic groove, causing the side plates to slide in the side grooves, compressing and contracting the telescopic rods and springs, inserting the tube downwards into the bottle body, placing the tube sleeve at the bottle mouth, and releasing the tension on the clamping rings. The telescopic rods and springs push the side plates, causing the telescopic plate to slide inwards into the telescopic grooves, thus allowing the clamping rings on both sides to move towards each other and clamp onto the outside of the bottle body, making the installation of the extraction device more convenient.

Detailed Implementation

[0031] 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, not all, of the embodiments of this utility model.

[0032] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] As shown in Figures 1-5, this embodiment proposes a liquid food detection extraction device to prevent sample contamination, including a tube sleeve 1, a buckling assembly inside the tube sleeve 1, outer plates 3 on both sides of the tube sleeve 1, and clamping assemblies on the outer sides of the outer plates 3.

[0036] The buckle assembly includes an inner tube 201 that can be movably disposed inside the sleeve 1, an insertion tube 202 that is connected to the lower end of the inner tube 201, and a pull tube 203 that can be retracted and extended inside the upper side of the insertion tube 202.

[0037] The clamping assembly includes a telescopic groove 401 inside the outer plate 3, and a telescopic plate 402 is movably disposed inside the telescopic groove 401. A clamping ring 403 is disposed at the lower end of the side of the telescopic plate 402 away from the sleeve 1.

[0038] As shown in Figure 3, an inner groove 204 is provided inside the sleeve 1 on the right side of the inner tube 201. A first bevel gear 205 is provided inside the upper end of the inner groove 204. A knob 206 is connected to the upper end of the first bevel gear 205. Twisting the knob 206 drives the first bevel gear 205 connected to it to rotate, drives the second bevel gear 207 connected to it to rotate, drives the screw 209 connected to it to rotate, and meshes with it to drive the clamping plate 210 to slide in the slot 208. Under the limitation of the limiting plate 212 embedded in the limiting groove 211, the clamping plate 210 slides stably towards the inner tube 201, and the surface of the clamping plate 210 clamps the inner tube 201 with the frosted material, positioning it inside the sleeve 1.

[0039] As shown in Figure 3, the inner wall of the inner groove 204 near the inner tube 201 is provided with a second bevel gear 207 that cooperates with the first bevel gear 205. When the first bevel gear 205 rotates, it drives the second bevel gear 207 connected to it to rotate, which in turn drives the screw 209 connected to it to rotate. The meshing causes the clamping plate 210 to slide in the slot 208.

[0040] As shown in Figure 3, the inner groove 204 has a slot 208 on the outer side near the inner tube 201. A screw 209 is installed inside the slot 208. A clamping plate 210 is fitted on the outer wall of the screw 209. The clamping plate 210 slides stably toward the inner tube 201, so that the surface of the clamping plate 210 clamps the inner tube 201 with a frosted material and positions it inside the tube sleeve 1, thereby realizing the rapid adjustment of the insertion height of the insertion tube 202 into the liquid.

[0041] As shown in Figure 3, a limiting groove 211 is provided on the upper side of the slot 208, and a limiting plate 212 that cooperates with the limiting groove 211 is provided on the upper side of the clamping plate 210. Under the limiting of the limiting plate 212 embedded in the limiting groove 211, the clamping plate 210 slides stably towards the inner tube 201, and the surface of the clamping plate 210 clamps the inner tube 201 with the frosted material, positioning it inside the sleeve 1.

[0042] As shown in Figure 5, the side wall of the telescopic groove 401 is provided with a side groove 404, and the side wall of the telescopic plate 402 is provided with a side plate 405 that cooperates with the side groove 404. The side plate 405 slides in the side groove 404, compressing and contracting the telescopic rod 406 and the spring 407, inserting the insertion tube 202 downward into the bottle body, placing the tube sleeve 1 at the bottle mouth, releasing the tension on the clamping ring 403, and the telescopic rod 406 and the spring 407 push the side plate 405 to drive the telescopic plate 402 to slide into the telescopic groove 401.

[0043] As shown in Figure 5, a telescopic rod 406 is connected to the side wall of the side plate 405. A spring 407 is fitted on the outer wall of the telescopic rod 406. When the telescopic rod 406 and the spring 407 are compressed and contracted, the insertion tube 202 is inserted downward into the bottle body, so that the tube sleeve 1 is placed at the bottle mouth. When the tension on the clamping ring 403 is released, the telescopic rod 406 and the spring 407 push the side plate 405 to drive the telescopic plate 402 to slide into the telescopic groove 401, so that the clamping rings 403 on both sides can move towards each other and clamp the bottle body.

[0044] Specifically, when using this extraction device: When it is necessary to adjust the height of the insertion tube 202, pull the inner tube 201 up and down to move it within the sleeve 1. After adjustment, turn the knob 206 to rotate the first bevel gear 205 connected to it, which in turn rotates the second bevel gear 207 connected to it, causing the screw 209 connected to it to rotate. This meshes and causes the clamping plate 210 to slide within the slot 208. With the limiting plate 212 embedded in the limiting groove 211, the clamping plate 210 slides stably towards the inner tube 201. The surface of the clamping plate 210, through the frosted material, clamps the inner tube 201, positioning it inside the sleeve 1. This allows for rapid adjustment of the insertion height of the insertion tube 202 into the liquid. Pulling up the suction tube 203 allows liquid to be drawn into the insertion tube 202 for efficient use. When the extraction device needs to be installed on the upper side of the bottle containing the liquid, pull the clamping rings 403 outwards on both sides to move the telescopic plate 402 in and out of the telescopic groove 401, causing the side plate 405 to slide in the side groove 404, compressing and contracting the telescopic rod 406 and the spring 407, inserting the insertion tube 202 downwards into the bottle, placing the tube sleeve 1 at the bottle mouth, and releasing the pull on the clamping rings 403. The telescopic rod 406 and the spring 407 push the side plate 405, causing the telescopic plate 402 to slide inwards into the telescopic groove 401, so that the clamping rings 403 on both sides move towards each other and clamp onto the outside of the bottle, making the installation of the extraction device more convenient.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
