Description

Technical Field

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

[0002] Food safety testing is to detect harmful substances in food in accordance with food safety standards, mainly some toxic and harmful indicators, such as heavy metals, aflatoxin, etc. After the food is processed, it is necessary to take a part of the finished food for sampling. Due to the nature of the sample and the requirements of the inspection project, different methods need to be adopted. For liquid food sample testing, it is usually necessary to shake the sample thoroughly.

[0003] During the food testing process of traditional food testing devices, test tubes are usually required to test food. During the testing, the staff adds the corresponding solvent into the test tube and shakes it manually to speed up the mixing efficiency of the food sample and the solution. Since there are many samples to be tested, the staff needs to shake it multiple times, and it is difficult to ensure the consistency of each shaking, which may affect the reliability of the test results.

[0004] Therefore, it is necessary to design a food shaking device that can shake multiple test tubes simultaneously. Utility Model Content

[0005] In order to overcome the disadvantage that the staff shakes the sample multiple times and continuously, and the mixing efficiency of each shaking is different, which leads to errors in detection, the technical problem of the utility model is to provide a food shaking device that can shake multiple test tubes at the same time.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model provides the following technical solution: The technical solution of the utility model is: a food shaking device for food testing, including a chassis, a placing ring, a connecting rod, a connecting plate, a limiting ring and a test tube, a plurality of placing rings are fixedly connected to the side of the chassis, a connecting rod is fixedly connected to the chassis, a connecting plate is fixedly connected to the connecting rod, and a plurality of limiting rings are arranged on the side of the connecting plate, a test tube is placed on the placing ring and is limited by the limiting ring, and also includes a universal ball, a connecting seat and a rocker arm, a universal ball is fixedly connected to the top of the connecting rod, a connecting seat is hinged on the universal ball, and a rocker arm is fixedly connected to the top of the connecting seat.

[0007] In one of the embodiments, it also includes a clamping plate, a guide rod and an elastic member. Two guide rods are symmetrically and slidingly arranged in the placement ring and the limiting ring. The guide rods are fixed with clamping plates, and the guide rods pass through the placement ring and the limiting ring. The elastic member is sleeved on the guide rods.

[0008] In one of the embodiments, it also includes a fixed frame, a winding wheel, an anti-slip belt, a patch, an adhesive sheet and a torsion spring. The fixed frame is fixedly connected to the top of the connecting seat, and the winding wheel is rotatably arranged on the fixed frame. The anti-slip belt is wound on the winding wheel. The patch is arranged on the side of the anti-slip belt close to the winding wheel, and the adhesive sheet is arranged on the side of the winding wheel away from the patch. A torsion spring is connected between the fixed frame and the winding wheel.

[0009] In one of the embodiments, a sealing plug is provided on the top of the test tube.

[0010] In one embodiment, the cross-section of the lower end of the test tube is elliptical.

[0011] In one embodiment, a plurality of anti-skid pads are disposed on the inner side of the clamping plate to increase the friction of the test tube when shaking.

[0012] In one of the embodiments, a fluorescent sticker for observing the rotational orientation of the test tube is provided on the connection disk.

[0013] Compared with the prior art, the shaking device provided by the embodiment of the utility model has the following advantages: 1. Through the hinged cooperation between the universal ball and the connecting seat, the swing angle and amplitude of the test tube can be greatly improved. The rocker on the connecting seat allows the staff to shake the tube conveniently, and at the same time, the shaking detection of multiple test tubes can be carried out at one time, and the randomness of the detection can be avoided, thereby improving the reliability of the experimental data.

[0014] 2. Since a large shaking amplitude may cause the test tube to be thrown out of the device, insert the test tube into the two clamps. When the lower end of the test tube contacts the clamps, the clamps are stretched open. When away from the lower end of the test tube, the clamps firmly clamp the outer wall of the test tube, thereby preventing the test tube from being thrown out when shaking greatly.

[0015] 3. When the device is shaking, in order to prevent the device from being thrown out, the staff can pull out the anti-slip belt, wrap the anti-slip belt around the wrist and stick the patch together, and tighten the anti-slip belt to the wrist under the reset action of the torsion spring. If the device needs to be separated from the wrist, pull the adhesive sheet to separate from the patch, and the spring resets to completely reel in the anti-slip belt.

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0024] Embodiment 1: A food shaking device for food testing, such as Figure 1-6 As shown, it includes a chassis 1, a placement ring 101, a connecting rod 2, a connecting plate 3, a limiting ring 301 and a test tube 302. Four placement rings 101 are welded along the circumferential direction on the side of the chassis 1, a connecting rod 2 is welded on the chassis 1, a connecting plate 3 is welded on the connecting rod 2, and four limiting rings 301 are welded around the side of the connecting plate 3. A test tube 302 is placed on the placement ring 101 and is limited by the limiting ring 301. It also includes a universal ball 4, a connecting seat 5 and a rocker 6. A universal ball 4 is welded on the top of the connecting rod 2, a connecting seat 5 is hinged on the universal ball 4, a rocker 6 is welded on the top of the connecting seat 5, and a sealing plug is slidably arranged on the top of the test tube 302.

[0025] When the device is used to shake food, the staff first puts the food samples into the test tube 302 evenly in turn, drips the corresponding solvent into the test tube 302, and then covers the test tube 302 with a sealing plug. After that, the test tube 302 is placed in each placement ring 101 and the limit ring 301, and then the staff shakes the device. Through the hinged cooperation between the universal ball 4 and the connecting seat 5, the shaking angle and swing amplitude of the test tube 302 can be greatly improved, and the rocker 6 set on the connecting seat 5 can make it more convenient for the staff to shake, and at the same time, it is possible to perform shaking detection on multiple test tubes 302 at one time, and avoid the accidental detection, thereby improving the reliability of experimental data.

[0026] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 4As shown, it also includes a splint 7, a guide rod 8 and an elastic member 9. Two guide rods 8 are symmetrically and horizontally slidably arranged in the placement ring 101 and the limiting ring 301. The guide rods 8 are welded with splints 7. The inner side of the splint 7 is provided with a plurality of anti-slip pads 16 for increasing the contact friction of the test tube 302 when shaking. The guide rods 8 pass through the placement ring 101 and the limiting ring 301. The elastic member 9 is sleeved on the guide rods 8. The cross-section of the lower end of the test tube 302 is elliptical. The connecting disk 3 is provided with a fluorescent sticker 17 for observing the rotation direction of the test tube 302.

[0027] When the device is shaken, the test tube 302 may be thrown out of the device due to the large shaking amplitude. The test tube 302 is directly inserted into the two clamps 7. Since the cross-section of the lower end of the test tube 302 is elliptical, when the test tube 302 is inserted into the two clamps 7, the clamps 7 are stretched open when the lower end of the test tube 302 contacts the clamps 7. When it is away from the lower end of the test tube 302, the clamps 7 firmly clamp the outer wall of the test tube 302, thereby preventing the test tube 302 from being thrown out when it is shaken greatly.

[0028] like Figure 5 and Figure 6 The device shown also includes a fixing frame 10, a winding wheel 11, an anti-slip belt 12, a patch 13, an adhesive sheet 14 and a torsion spring 15. The fixing frame 10 is welded on the top of the connecting seat 5. The winding wheel 11 is rotatably arranged on the fixing frame 10. The anti-slip belt 12 is wound on the winding wheel 11. The patch 13 is provided on the side of the anti-slip belt 12 close to the winding wheel 11 by bonding. The adhesive sheet 14 is provided on the end of the winding wheel 11 away from the patch 13 by bonding. A torsion spring 15 is connected between the fixing frame 10 and the winding wheel 11.

[0029] When the device is shaking, in order to prevent the device from being thrown out, the staff can pull the anti-slip belt 12 out of the winding wheel 11. At this time, the winding wheel 11 rotates clockwise, and the torsion spring 15 is squeezed and deformed by the winding wheel 11, and the anti-slip belt 12 is wound around the wrist. When the adhesive sheet 14 and the patch 13 are bonded together, the anti-slip belt 12 is loosened, and the torsion spring 15 can be reset to a certain state to tighten the anti-slip belt 12 counterclockwise to the wrist. If the device needs to be detached from the wrist, the adhesive sheet 14 can be pulled to detach from the patch 13, and then the spring can be completely reset and the winding wheel 11 can be rotated counterclockwise to completely reel in the anti-slip belt 12. Repeat the above operation to put the wrist and the device together.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
