[0033] Among them, by setting the plug hole 111, when the plug plate 110 is installed between the side plates 102, the test tube is inserted into the plug hole 111, and the bottom wall of the test tube is abutted against the bottom plate 101, thereby, the test tube can be placed upright on the test tube rack in a better manner;

[0034] Among them, a plurality of slots 103 are arranged relatively along the height direction of the side plate 102, so that the plug board 110 is inserted into the slots 103 at different heights, and the height adjustment between the plug board 110 and the bottom plate 101 can be achieved, so that the plug board 110 can be plugged with test tubes of different lengths, that is, the test tube rack can be plugged with test tubes of different lengths, thereby improving the applicability of the test tube rack;

[0035] Among them, by the relative arrangement of the plug plates 110, the two plug plates 110 can be inserted into the slots 103 at different positions on both sides of the side plate 102, so that the test tube rack can simultaneously insert and place test tubes of different lengths, thereby preferably improving the applicability of the test tube rack;

[0036] In actual use, in order to facilitate the insertion of the plugboard 110 into the corresponding slot 103, the slot 103 on one of the two side plates 102 is not provided through, so that the plugboard 110 is inserted into the slot 103 through the through slot 103, and the plugboard 110 can be positioned better to prompt that it is inserted into place;

[0037] The fixing mechanism is provided so that the fixing mechanism can fix the inserting plate 110 in the slot 103, thereby preventing the inserting plate 110 from being separated from the slot 103 and affecting the insertion and placement of the test tube thereon;

[0038] In actual use, the length of the plug board 110 is longer than the distance between the side panels 102, that is, when the plug board 110 is inserted into the slot 103, one end of the plug board 110 can be located outside the side panel 102. At this time, in order to facilitate the pulling out of the plug board 110, a notch 312 is provided at the end of the plug board 110 located outside the side panel 102, so that the user can hold the notch 312 to pull out the plug board 110;

[0039] When it is actually used, the fixing mechanism is arranged at the center position of the side plate 102, and is used to fix the plug-in plates 110 in the slots 103 on both sides thereof, thereby making a certain gap exist between the two plug-in plates 110 plugged into the frame 100. When it is actually used, the drain columns 104 are evenly arranged on the bottom plate 101 and between the opposite plug-in plates 110, so that the cleaned test tubes can be plugged into the corresponding drain columns 104 for draining, thereby facilitating the drying of the test tubes for subsequent use of the test tubes.

[0040] Combination Figure 3-6 As shown, in this embodiment, a positioning hole 311 is provided on the side of the plug board 110; the fixing mechanism includes a horizontal groove 401 provided in the side plate 102 along the width direction of the side plate 102, and a retractable positioning pin 410 is provided in the horizontal groove 401 and one end of the positioning pin extends into the corresponding slot 103, and the positioning pin 410 extends into the positioning hole 311 to fix the plug board 110.

[0041] Through the structure in this embodiment, when the plug board 110 is inserted into the corresponding slot 103 and plugged into place, the positioning pin 410 in the horizontal slot 401 is extended to be inserted into the corresponding positioning hole 311 to fix the plug board 110. The positioning pin 410 in the horizontal slot 401 is retracted to release the fixation of the plug board 110. At this time, the plug board 110 can be pulled out and pulled out in the slot 103.

[0042] In this embodiment, a vertical groove 402 connected to the horizontal groove 401 is provided in the side plate 102 along its height direction, and a lifting plate 420 that can be lifted and lowered is relatively provided in the vertical groove 402. A convex block 421 is provided on the side of the lifting plate 420 that is away from each other and corresponds to the horizontal groove 401. A first inclined surface 422 is provided on the convex block 421. A first spring 400 for driving the lifting plate 420 to move downward is provided in the vertical groove 402;

[0043] A sliding block 430 is slidably provided in the horizontal groove 401, and a positioning pin 410 is connected to the corresponding sliding block 430. The sliding block 430 is provided with a second inclined surface 431 that matches the first inclined surface 422. A second spring 440 for driving the sliding block 430 to move toward the protrusion 421 is sleeved on the positioning pin 410 located in the horizontal groove 401. The lifting plate 420 moves downward to drive the first inclined surface 422 to squeeze the second inclined surface 431 to enable the sliding block 430 to slide into the horizontal groove 401.

[0044] In actual use of this embodiment, the two lifting plates 420 slide and fit with each other, wherein the protrusions 421 are arranged on the sides of the lifting plates 420 that are away from each other, and the side walls of the protrusions 421 and the lifting plates 420 slide and fit with the side walls of the vertical groove 402, and the side walls of the sliding block 430 slide and fit with the side walls of the horizontal groove 401, thereby, under the action of the first spring 400, the lifting plates 420 and the protrusions 421 are smoothly lifted and lowered in the vertical groove 402, and in the process of their downward movement, During the process, the first inclined surface 422 squeezes the second inclined surface 431, so that the sliding block 430 slides into the corresponding horizontal groove 401, so that the positioning pin 410 extends out of the horizontal groove 401 to the corresponding slot 103; when it is actually used, the upper end of the vertical groove 402 is open, and a blocking plate 403 is provided at the opening, the upper end of the first spring 400 abuts on the blocking plate 403, and the lower end abuts on the uppermost protrusion 421, thereby preferably realizing the installation of the first spring 400 in the vertical groove 402;

[0045] Among them, through the setting of the second spring 440, when the lifting plate 420 moves upward in the vertical slot 402 and drives the protrusion 421 to move upward, the second spring 440 pushes the sliding block 430 to slide toward the vertical slot 402, thereby driving the positioning pin 410 to retract into the horizontal slot 401, thereby facilitating the pulling and pulling of the plug board 110 in the slot 103; in actual use, the elastic force of the second spring 440 is less than the elastic force of the first spring 400, so that in the initial state, the lifting plate 420 moves downward and drives the positioning pin 410 to extend into the corresponding slot 103.

[0046] Combination Figure 2 and Figure 6 As shown, in this embodiment, a sliding groove connected to the vertical groove 402 is provided on the outer side surface of the side plate 102 along its height direction, and a shifting post 611 is provided on the side surface of the protrusion 421 and extends through the corresponding sliding groove.

[0047] Through the structure of this embodiment, in actual use, by moving the corresponding lever 611 upward along the slide slot, the corresponding lifting plate 420 can be moved upward, thereby retracting the positioning pin 410 into the horizontal slot 401, thereby facilitating the pulling and drawing of the plug board 110;

[0048] Among them, in order to facilitate the installation of the lifting plate 420, the sliding block 430, the positioning pin 410 and the second spring 440 in the side panel 102, the vertical groove 402 is set to open toward the outside of the side panel 102, and a back panel 200 is provided at the opening for sealing it, and the sliding groove is provided on the back panel 200, thereby better realizing the installation of the fixing mechanism on the side panel 102.

[0049] Working principle: According to the length of the test tube, the corresponding lever 611 is moved up along the slide slot, thereby driving the positioning pin 410 to retract into the horizontal slot 401. At this time, the plug plate 110 is pulled out of the slot 103 and inserted into the slot 103 at the corresponding position. Then the lever 611 is released, which can make the positioning pin 410 automatically extend out of the horizontal slot 401 to the corresponding slot 103, so that the positioning pin 410 is automatically inserted into the corresponding positioning hole 311, and the plug plate 110 is fixed. Then, the test tube is inserted into the plug hole 111, and the test tube can be placed upright on the test tube rack.

[0050] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
