Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A test tube rack with high stability comprises a base 1, a lifting mechanism is arranged on the surface of the base 1, a panel 11 is fixedly connected to the top of the lifting mechanism, a plurality of groups of holes are provided on the surface of the panel 11, depressions corresponding to the holes are provided on the surface of the base 1, so as to facilitate the placement of test tubes, a stabilizing mechanism is arranged at the bottom of the base 1, the stabilizing mechanism comprises a rotating assembly 2, the rotating assembly 2 is rotatably connected to the bottom of the base 1, a rotating rod 21 is fixedly connected to the bottom of the rotating assembly 2, a fixing plate 22 is fixed on the surface of the base 1, a first spring 23 is fixedly connected to the surface of the fixing plate 22, a limiting plate 24 is fixedly connected to the top of the first spring 23, the limiting plate 24 slides on the surface of the rotating assembly 2, and the stabilizing mechanism expands the support range of the test tube rack through the rotating rod 21, thereby improving the stability of the test tube rack.

[0024] Furthermore, the lifting mechanism includes a vertical rod 3, which is fixedly connected to the surface of the base 1, and a lifting rod 31 is slidably connected to the surface of the vertical rod 3. The panel 11 is fixedly connected to the top of the lifting rod 31, and a second spring 32 is fixedly connected to the surface of the vertical rod 3. A limiting rod 33 is fixedly connected to the surface of the second spring 32, and the limiting rod 33 is slidably connected to the surface of the vertical rod 3. A positioning hole 34 is provided on the surface of the lifting rod 31. The lifting mechanism can change the horizontal height of the panel 11 on the base 1, so that the panel 11 can limit test tubes of different heights, thereby improving the flexibility of the test tube rack.

[0025] Furthermore, a groove is provided at the bottom of the base 1, and the rotating rod 21 rotates on the groove of the base 1 through the rotating component 2. Four groups of rotating rods 21 are arranged at the bottom of the base 1. The bottom of the rotating rod 21 and the bottom of the base 1 both contact the ground. The rotating rod 21 can be completely rotated on the groove at the bottom of the base 1. At this time, the stabilizing mechanism is retracted. When the rotating rod 21 is unfolded, the rotating rod 21 and the base 1 form an overall "H" shape, and the rotating rod 21 expands the support range of the base 1.

[0026] Furthermore, the limit plate 24 is in an "L" shape, and a guide hole is opened on the surface of the fixed plate 22. When the limit plate 24 slides on the guide hole of the fixed plate 22, the limit plate 24 is lifted and lowered on the surface of the base 1. The limit plate 24 is located at the end of the rotating rod 21 away from the rotating component 2, and the limit plate 24 can contact one end of the two groups of rotating rods 21 at the same time.

[0027] Furthermore, the elastic force of the first spring 23 acts on the limit plate 24, and the bottom of the limit plate 24 and the rotating rod 21 are at the same horizontal height. The limit plate 24 limits the rotation of the rotating rod 21 at the bottom of the base 1, so that the rotating rod 21 is in the groove at the bottom of the base 1. The limit plate 24 is pulled on the fixed plate 22 to make the limit plate 24 rise, and the restriction of the limit plate 24 on the rotating rod 21 can be cancelled.

[0028] Furthermore, a guide groove is provided on the surface of the vertical rod 3, and the lifting rod 31 slides on the guide groove of the vertical rod 3. The lifting rod 31 changes the horizontal height of the panel 11 on the guide groove of the vertical rod 3. The lifting rod 31 changes the supporting position of the holes on the panel 11 for the test tube, thereby facilitating the limiting of test tubes of different heights and improving the flexibility of the test tube rack.

[0029] Furthermore, a plurality of positioning holes 34 are provided, and the positioning holes 34 are linearly and evenly arranged on the surface of the lifting rod 31. Circular holes begin to appear on the surface of the vertical rod 3. The circular holes of the vertical rod 3 are connected to the guide groove of the vertical rod 3. The limiting rod 33 slides on the circular holes of the vertical rod 3. The limiting rod 33 passes through a group of positioning holes 34 on the guide groove of the vertical rod 3. The limiting rod 33 limits the height of the lifting rod 31 on the surface of the vertical rod 3, and the lifting rod 31 further limits the horizontal height of the panel 11.

[0030] Working principle: Pull the limit plate 24 upward on the surface of the fixed plate 22 to deform the first spring 23 so that the bottom of the limit plate 24 is higher than the top of the rotating rod 21. The limit plate 24 cannot limit the rotation of the rotating rod 21 at this time. At this time, the rotating rod 21 can be rotated on the groove of the base 1 through the rotating component 2, and the four groups of rotating rods 21 are rotated ninety degrees at the bottom of the base 1. At this time, the rotating rod 21 expands the support range of the bottom of the base 1, improves the stability of the test tube rack, avoids the test tube from breaking, and ensures the safety of the test tube.

[0031] The limiting rod 33 is pulled in the circular hole of the base 1, the second spring 32 is deformed, and the lifting rod 31 slides on the guide groove of the vertical rod 3. The lifting rod 31 changes the horizontal height of the panel 11. At this time, the limiting rod 33 is released. Under the elastic force of the second spring 32, the limiting rod 33 slides on the circular hole of the vertical rod 3. The limiting rod 33 will pass through one of the groups of positioning holes 34 on the guide groove of the vertical rod 3. The limiting rod 33 limits the height of the lifting rod 31 through the positioning holes 34, thereby completing the change of the horizontal height of the panel 11.
