Description

Technical Field

[0001] This utility model relates to the field of agricultural product quality testing technology, specifically to a test tube shaking device for agricultural product quality testing. Background Technology

[0002] Agricultural product quality testing refers to the process of testing and analyzing indicators such as nutritional components, pesticide residues, and microbial contamination of agricultural products using scientific technical means and methods. During the testing process, agricultural product samples, such as crushed vegetables or fruit juice, need to be mixed with test reagents, and a test tube shaking device is used to ensure that the sample and reagents are in full contact through mechanical vibration.

[0003] Currently, the clamps of test tube shaking devices are not strong enough during use. Most traditional clamps only fix the test tubes by side clamping force, without considering the vertical direction during shaking. This makes the test tubes easy to loosen under multi-directional force, which can lead to the test tubes falling off or the caps loosening during shaking, resulting in sample spillage. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A test tube shaking device for agricultural product quality testing, comprising:

[0006] A base, with a vertical tube connected to the upper middle position of the base, an elastic mechanism provided on the outside of the vertical tube, a T-shaped cylinder connected to the outside of the elastic mechanism, the bottom of the T-shaped cylinder being fixedly connected to the base, and an oscillation mechanism provided at the bottom of the vertical tube;

[0007] Three fixing brackets are circumferentially connected to the outer side of the vertical tube near the top position. A back plate is connected to one side of each fixing bracket. An upper clamping mechanism is provided on the outer side of the back plate at the top position, a side clamping mechanism is provided on the outer side of the back plate at the middle position, and a lower clamping mechanism is provided on the outer side of the back plate at the bottom position.

[0008] In one possible implementation, the upper clamping mechanism includes a top plate, one side of which is fixedly connected to a back plate. A first screw hole is provided inside the top plate, and a second screw is threaded into the first screw hole. A first knob is connected to the top end of the second screw, and a first bearing is rotatably connected to the end of the second screw. An upper clamping plate is connected to the bottom of the first bearing.

[0009] In one possible implementation, the side clamping mechanism includes a pair of side plates, both of which are fixedly connected to a back plate. A second screw hole is provided inside the side plate, and a first screw is threaded into the second screw hole. A second knob is connected to one end of the first screw, and a second bearing is rotatably connected to the other end of the first screw. A side clamping plate is connected to one side of the second bearing.

[0010] In one possible implementation, the lower clamping mechanism includes a base plate, one side of which is fixedly connected to a back plate, and a sleeve is connected above the base plate, with a protective pad connected inside the sleeve.

[0011] In one possible implementation, the elastic mechanism includes a plurality of first springs circumferentially connected to the outside of the vertical tube, one end of each first spring being fixedly connected to a T-shaped cylinder.

[0012] In one possible implementation, the oscillation mechanism includes a fixed plate, the top of which is fixedly connected to a vertical tube, a vibration motor connected to the middle of the bottom of the fixed plate, and three second springs circumferentially connected to the bottom of the fixed plate, the ends of which are fixedly connected to a base.

[0013] In one possible implementation, a nitrile rubber pad is attached to the bottom of the base.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. By placing the bottom of the test tube inside the sleeve and rotating the second knobs on both sides, the first screw is rotated. Through the cooperation between the first screw, the second screw hole, and the second bearing, the side clamps on both sides are easily driven to clamp the test tube. Then, rotating the first knob again drives the second screw to rotate. Through the cooperation between the second screw, the first screw hole, and the first bearing, the upper clamp is further driven to descend, pressing the top cap of the test tube. The combination of the three forms a three-way constraint of lower positioning, side clamping, and upper cap pressing, which improves the fixing force of the clamp and helps to prevent the test tube from falling off or the cap from loosening.

[0016] 2. By setting a nitrile rubber pad at the bottom of the base and a protective pad at the bottom of the sleeve, the nitrile rubber, with its high coefficient of friction and elasticity, increases the friction between the base and the laboratory table. During high-frequency oscillation of the device, it can effectively prevent the overall displacement of the equipment due to vibration. The protective pad has a certain frictional force. When the bottom of the test tube is embedded in the sleeve, the protective pad can increase the tightness of the fit between the test tube and the inner wall of the sleeve, playing an auxiliary fixing effect and thus enhancing the vertical stability.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This application provides a test tube shaking device for agricultural product quality testing, thereby solving the problems in the prior art.

[0026] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0027] like Figures 1-4 As shown, a test tube shaking device for agricultural product quality testing includes:

[0028] A base 10 is connected to a vertical tube 3 at the top center of the base 10. An elastic mechanism is provided on the outside of the vertical tube 3. A T-shaped tube 9 is connected to the outside of the elastic mechanism. The bottom of the T-shaped tube 9 is fixedly connected to the base 10. An oscillation mechanism is provided at the bottom of the vertical tube 3.

[0029] Three fixing brackets 25 are circumferentially connected to the outer side of the vertical tube 3 near the top position. A back plate 2 is connected to one side of the fixing bracket 25. An upper clamping mechanism is provided on the outer side of the back plate 2 at the top position, a side clamping mechanism is provided on the outer side of the back plate 2 at the middle position, and a lower clamping mechanism is provided on the outer side of the back plate 2 at the bottom position.

[0030] In some examples, the upper clamping mechanism includes a top plate 1, one side of which is fixedly connected to a back plate 2. A first screw hole 17 is provided inside the top plate 1, and a second screw 23 is threadedly connected inside the first screw hole 17. A first knob 16 is connected to the top end of the second screw 23, and a first bearing 18 is rotatably connected to the end of the second screw 23. An upper clamping plate 4 is connected to the bottom of the first bearing 18. The first knob 16 drives the second screw 23 to rotate. The cooperation between the second screw 23, the first screw hole 17, and the first bearing 18 further drives the upper clamping plate 4 to descend, thereby pressing the top cover of the test tube.

[0031] In some examples, the side clamping mechanism includes a pair of side plates 5, both of which are fixedly connected to the back plate 2. The side plates 5 have a second screw hole 19 inside, and a first screw 20 is threadedly connected inside the second screw hole 19. One end of the first screw 20 is connected to a second knob 21, and the other end of the first screw 20 is rotatably connected to a second bearing 22. A side clamping plate 6 is connected to one side of the second bearing 22. Rotating the second knobs 21 on both sides drives the first screw 20 to rotate. Through the cooperation between the first screw 20, the second screw hole 19, and the second bearing 22, it is convenient to drive the side clamping plates 6 on both sides to clamp the test tube on both sides.

[0032] In some examples, the lower clamping mechanism includes a base plate 8, one side of which is fixedly connected to a back plate 2. A sleeve 7 is connected above the base plate 8, and a protective pad 24 is connected inside the sleeve 7. When the bottom of the test tube is placed inside the sleeve 7, the surface of the protective pad 24 has a certain friction. When the bottom of the test tube is embedded in the sleeve 7, the protective pad 24 can increase the tightness of the fit between the test tube and the inner wall of the sleeve 7, which plays an auxiliary fixing role and thus enhances the vertical stability.

[0033] In some examples, the elastic mechanism includes a plurality of first springs 12 circumferentially connected to the outside of the vertical tube 3, one end of the first spring 12 being fixedly connected to the T-shaped cylinder 9, which absorbs and buffers the relative displacement impact force between the vertical tube 3 and the T-shaped cylinder 9 during the oscillation of the device.

[0034] In some examples, the oscillation mechanism includes a fixed plate 13, the top of which is fixedly connected to the vertical tube 3, a vibration motor 15 connected to the middle of the bottom of the fixed plate 13, and three second springs 14 circumferentially connected to the bottom of the fixed plate 13. The ends of the second springs 14 are fixedly connected to the base 10. Turning on the vibration motor 15 helps to drive the vertical tube 3 to vibrate synchronously, thereby driving the three back plates 2 at the top of the vertical tube 3 and the test tube to vibrate synchronously.

[0035] In some examples, the bottom of the base 10 is connected to a nitrile rubber pad 11. Nitrile rubber has a high coefficient of friction and elasticity, which can increase the friction between the base 10 and the laboratory table surface. When the device vibrates at high frequency, it can effectively prevent the device from displacing due to vibration.

[0036] This invention places the bottom of the test tube inside the sleeve 7 and rotates the second knobs 21 on both sides to rotate the first screw 20. The cooperation between the first screw 20, the second screw hole 19, and the second bearing 22 facilitates the driving of the side clamps 6 on both sides to clamp the test tube. Then, rotating the first knob 16 rotates the second screw 23. The cooperation between the second screw 23, the first screw hole 17, and the first bearing 18 further drives the upper clamp 4 to descend and press the top cover of the test tube. The three together form a three-way constraint of lower positioning, side clamping, and upper pressing, which improves the fixing force of the clamp.

[0037] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
