[0002] With the continuous development of society, the continuous progress of science, and the continuous improvement of people's living standards, various types of equipment used to assist food testing have been continuously innovated and emerged, and the test tube rack for food testing is an important device in the auxiliary food testing equipment.

[0003] When a traditional test tube rack is in use, the height of the test tube rack is fixed and cannot be adjusted up and down. However, the lengths of test tubes vary, so the test tube rack cannot play a good placement role when placing some shorter test tubes, causing the test tubes to fall from the test tube rack and break. In addition, the bottom of the traditional test tube rack has a small contact area with the desktop, which can easily cause the test tube rack to topple over when shaking. The test tube rack is not stable enough when in use. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a food testing tube rack, which has the advantages of strong applicability and good stability, and solves the problems raised by the above-mentioned background technology.

[0005] The utility model provides the following technical scheme: a food inspection test tube rack, comprising a base, a vertical pole fixedly assembled on the top of the base, a telescopic pole movably sleeved in the inner cavity of the vertical pole, a fixed plate fixedly assembled on the outer wall of the vertical pole, a limiting plate fixedly assembled on the top of the telescopic pole, a vertical plate fixedly assembled on the top of the fixed plate, a fixing tube fixedly assembled on the outer wall of the vertical plate, a limiting ring fixedly assembled on the inner cavity of the vertical plate, a pull rod movably sleeved on the inner cavity of the vertical plate, a limiting ring fixedly assembled on the outer wall of the pull rod, a driving spring movably sleeved on the outer wall of the pull rod, a limiting groove is provided on the outer wall of the telescopic pole, and a left supporting plate is rotatably connected to the bottom of the base.

[0006] As a preferred technical solution of the utility model: the outer wall diameter of the limiting ring is larger than the outer wall diameter of the driving spring, and the inner wall of the limiting ring is smaller than the outer wall diameter of the driving spring.

[0007] As a preferred technical solution of the utility model: the outer wall diameter of the pull rod matches the inner wall diameter of the limiting groove, and the static length of the drive spring is greater than the distance from the limiting ring to the limiting ring.

[0008] As a preferred technical solution of the utility model: there are two vertical plates, and the two vertical plates are respectively installed on both sides of the top of the fixed plate.

[0009] As a preferred technical solution of the utility model: the outer wall diameter of the telescopic rod matches the inner wall diameter of the vertical rod, and the outer wall length of the telescopic rod matches the inner cavity length of the vertical rod.

[0010] As a preferred technical solution of the utility model: the bottom of the base is rotatably connected with a right supporting plate, and the outer wall of the right supporting plate is meshed with the outer wall of the left supporting plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The food inspection test tube rack has a limit groove on the outer wall of the telescopic rod and a pull rod arranged in the inner cavity of the vertical plate. The pull rod is driven to move under the action of a driving spring, so that the pull rod enters the limit groove of the telescopic rod, thereby fixing the telescopic rod. When the position of the telescopic rod needs to be adjusted, the position of the telescopic rod and the limit plate can be adjusted by pulling the pull rod, so that the equipment can be better suitable for test tubes of different lengths.

[0013] 2. The food inspection test tube rack rotates the connected left and right support plates in the inner cavity of the base.

[0022] By setting the left support plate 12 and the right support plate 13 at the bottom of the base 1, when the device is in normal use, the left support plate 12 is rotated so that the left support plate 12 rotates outward. During the rotation of the left support plate 12, the right support plate 13 can be rotated driven by the left support plate 12, so that the left support plate 12 and the right support plate 13 are unfolded synchronously, thereby making the device more stable during use.

[0023] In a preferred embodiment, the outer wall diameter of the limiting ring 6 is larger than the outer wall diameter of the driving spring 8 , and the inner wall of the limiting ring 9 is smaller than the outer wall diameter of the driving spring 8 .

[0024] By means of the limiting ring 6 provided on the outer wall of the pull rod 5 and the limiting ring 9 provided in the inner cavity of the vertical plate 14, a certain limiting effect is exerted on the driving spring 8 under the action of the limiting ring 6 and the limiting ring 9, so that the driving spring 8 can push the pull rod 5 to move inward, and under the action of the driving spring 8, the outer wall of the pull rod 5 enters into the inner cavity of the limiting groove 11, thereby fixing the telescopic rod 3 and adjusting the position of the telescopic rod 3.

[0025] In a preferred embodiment, the outer wall diameter of the pull rod 5 matches the inner wall diameter of the limiting groove 11 , and the static length of the drive spring 8 is greater than the distance between the limiting ring 6 and the limiting ring 9 .

[0026] By setting a pull rod 5 in the inner cavity of the vertical plate 14 and a driving spring 8 sleeved on the outer wall of the pull rod 5, the pull rod 5 enters the inner cavity of the limit groove 11 under the action of the driving spring 8, thereby limiting the position of the telescopic rod 3, so that the outer wall of the telescopic rod 3 can be adjusted up and down in the inner cavity of the vertical rod 2, thereby better adjusting the position of the limit plate 4.

[0027] In a preferred embodiment, there are two vertical plates 14 , and the two vertical plates 14 are respectively installed on both sides of the top of the fixing plate 10 .

[0028] By setting the vertical plate 14 on the top of the vertical plate 14, pull rods 5 are set in the inner cavities of the vertical plates 14 on both sides. At this time, under the action of the pull rods 5, the outer wall of the telescopic rod 3 can be restricted from both sides, so that the limiting plate 4 is more stable during use and can better support the test tube.

[0029] In a preferred embodiment, the outer wall diameter of the telescopic rod 3 matches the inner wall diameter of the vertical rod 2 , and the outer wall length of the telescopic rod 3 matches the inner cavity length of the vertical rod 2 .

[0030] By using the telescopic rod 3 movably sleeved in the inner cavity of the vertical pole 2, when the use height of the limit plate 4 needs to be adjusted, it is only necessary to change the position of the telescopic rod 3 in the inner cavity of the vertical pole 2, and lock the telescopic rod 3 through the pull rods 5 on both sides, so as to better achieve the adjustment of the position of the limit plate 4.

[0031] In a preferred embodiment: the bottom of the base 1 is rotatably connected to a right supporting plate 13 , and the outer wall of the right supporting plate 13 is meshed with the outer wall of the left supporting plate 12 .

[0032] By setting a left support plate 12 and a right support plate 13 at the bottom of the base 1, and the outer walls of the left support plate 12 and the outer walls of the right support plate 13 are meshed with each other, when the left support plate 12 is rotated, the right support plate 13 will move in the opposite direction of the left support plate 12. Therefore, when the left support plate 12 and the right support plate 13 are used to support the base 1, it is only necessary to rotate one of the left support plate 12 or the right support plate 13 to very conveniently achieve the supporting effect on the equipment.

[0033] Working principle: During the use of the above-mentioned equipment, the height and position of the limit plate 4 are adjusted according to the length of the placed test tube. At this time, it is only necessary to pull the pull rod 5 outward to compress the driving spring 8, so that the outer wall of the pull rod 5 moves out of the inner cavity of the limit groove 11, and then the position of the telescopic rod 3 in the inner cavity of the vertical rod 2 can be adjusted, so that the telescopic rod 3 drives the position of the limit plate 4 to move, so that the limit plate 4 can better fix the test tube. At this time, the left support plate 12 is rotated outward. During the rotation of the left support plate 12, the outer wall of the left support plate 12 and the outer wall of the right support plate 13 are engaged with each other, so that the left support plate 12 drives the right support plate 13 to rotate during the rotation, and then the left support plate 12 and the right support plate 13 are unfolded. After the left support plate 12 and the right support plate 13 are unfolded, they can support the entire device, making the device more stable during use and able to better place the test tube.
