Description

Technical Field

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

[0002] Test tubes are commonly used instruments in chemical laboratories. They are used as reaction containers for small amounts of reagents and are used at room temperature or when heated (they should be preheated before heating, otherwise the test tubes are prone to bursting). Test tubes can also be used to inspect the quality of food raw materials, auxiliary materials, semi-finished products, finished products and by-products to ensure that the product quality is qualified.

[0003] For example, patent CN220677882U discloses a test tube for food testing, including a test tube and a top cover, wherein the upper half of the top cover is provided with a pressing device, and the lower half of the top cover is provided with a rotating device, and the rotating device includes a sealing mechanism and a rotating mechanism, wherein the sealing mechanism is provided at the bottom of the sliding cover, and the rotating mechanism is provided inside the sealing mechanism.

[0004] Although the above-mentioned test tube has the corresponding functions of stirring the sample inside the test tube and cleaning its inner wall during use, the switching between these two modes still requires manual change operation by personnel, and the switching method is as follows: the personnel need to hold the stirring component out of the test tube in advance, and then place the cleaning component into the test tube. During this process, the stirring component may carry the sample and drip to the outside, which poses certain safety hazards, and frequent switching also reduces the detection efficiency. Therefore, the present application provides a test tube for food testing to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a test tube for food testing to solve the problem that although the existing test tube also has corresponding functions of stirring the sample inside the test tube and cleaning the inner wall, the switching between the two modes still requires manual switching operations by personnel, and the switching method is as follows: the personnel need to hold the stirring component out of the test tube in advance, and then put the cleaning component into the test tube. During this process, the stirring component may carry the sample to drip outside, which has certain safety hazards, and the frequent switching also reduces the problem of detection efficiency.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A test tube for food testing comprises a tube body, a sealing mechanism is installed on the top of the tube body, and an anti-slip ring sleeve is fixed on the periphery of the tube body near the upper end, a portable switching mechanism is installed inside the tube body, the portable switching mechanism comprises a rotating rod 1 and a rotating rod 3, and a hand-held mechanism is installed on one side of each of the rotating rod 1 and the rotating rod 3, scales are distributed on both sides of the periphery of the tube body, stirring components are installed on both sides of the middle of the rotating rod 1, a rotating rod 3 is installed below the rotating rod 1 inside the tube body, and a cleaning component is installed below the rotating rod 3.

[0008] Optionally, the rotating rod 1 and the rotating rod 3 are both installed inside the tube body, and the rotating rod 1 and the rotating rod 3 are cross-distributed up and down.

[0009] Optionally, the stirring assembly includes a bevel gear 1, and the bevel gear 1 is fixedly sleeved on both sides of the middle part of the rotating rod 1, one side of the two bevel gears 1 is meshed with a bevel gear 2, and one end of the rotating rod 2 is fixed to the middle part of the two bevel gears 2, stirring rods are distributed on both sides of the two rotating rods 2, and a bearing ring 1 is fixed to the periphery of the two rotating rods 2 near the upper end, and a fixing frame 1 is fixed to the external connection of the bearing ring 1.

[0010] Optionally, the cleaning assembly includes a bevel gear three, and the bevel gear three is fixedly sleeved on one side of the middle part of the rotating rod three, one side of the bevel gear three is meshed with a bevel gear four, and one end of the rotating rod four is fixed to the middle part of the bevel gear four, a bearing ring two is fixed to the periphery of the rotating rod four close to the upper end, and a fixing frame two is fixed to the outside of the bearing ring two, connecting frames are fixed to both sides of the bottom end of the rotating rod four, and scraping plates are fixed to both side edges of the connecting frame.

[0011] Optionally, the sealing mechanism includes a threaded groove, and the threaded groove is opened in the upper middle part of the tube body, a threaded plug is screwed on the middle part of the threaded groove, and a rubber sealing ring is sleeved on the inner side of the end of the threaded plug.

[0012] Optionally, the hand-held mechanism includes a fixed ring sleeve, and the fixed ring sleeve is fixedly sleeved on the periphery of one end of the rotating rod one and the rotating rod three respectively, a connecting piece is fixedly provided on one side of the fixed ring sleeve, and the outer side of one end of the connecting piece is connected to the hand-held rod.

[0013] Compared with the prior art, the utility model has at least the following beneficial effects:

[0014] In the above scheme, by setting a portable switching mechanism, in order to ensure the data accuracy of the sample solution during the sample detection operation, the personnel can manually rotate the hand-held mechanism on one side of the rod one in advance to rotate it. At this time, the bevel gear one arranged on the periphery of the two sides of the rotating rod one will be rotated synchronously and drive the respective meshing bevel gear two and the middle rotating rod two to rotate. At this moment, the stirring rods evenly distributed around the rotating rod two of two different lengths can evenly mix the sample solution. Compared with manual shaking, it is safer and saves time and effort. When the detection is completed and needs to be cleaned, the personnel can pour out the solution and add cleaning liquid in the tube, and then manually rotate the hand-held mechanism on one side of the rod three. In this process, the fixed bevel gear three set on one side of the middle part of the rotating rod three will mesh with the bevel gear four and the middle rotating rod four to rotate.

In order to ensure its sealing effect, a rubber sealing ring is provided at the inner end of the threaded plug. When the thread is screwed in a certain distance, the rubber sealing ring will be stuck between the threaded plug and the threaded groove to form a seal, thereby ensuring the sealing safety of the sample in the test tube body.

[0016] By setting up a hand-held mechanism, it is worth mentioning that the fixing ring sleeve and the connecting piece are respectively connected around one end of the rotating rod one and the rotating rod three, and the hand-held rod is connected to the outside of one side of the connecting piece. This is more ergonomic and convenient for manual rotation of the two rotating rods. BRIEF DESCRIPTION OF THE DRAWINGS
