[0027] EMBODIMENT

[0028] As Figs. 1-5 Shown, a test tube rack in clinical laboratory, including base 1, base 1 is provided with placing seat 2 by elastic component, using elastic component to give the bottom of placing seat 2 power, make it have the tendency of moving upward, facilitate its with both sides guide frame 3 cooperation uses.

[0029] Vertical slot 31 is provided with inclined bifurcated slot 32 on the side surface of guide frame 3, and the both sides of placing seat 2 are clamped in vertical slot 31 or bifurcated slot 32 by limit block 21, limit block 21 can move along the slot body, and under the push of bottom elastic component, it moves in vertical slot 31 or bifurcated slot 32, until it moves to the top end of vertical slot 31 or bifurcated slot 32; when limit block 21 is at the top end of vertical slot 31, placing seat 2 is vertically arranged, at this time, the test tube placed in placing seat 2 is also in vertical state; when limit block 21 is at the top end of bifurcated slot 32, placing seat 2 is arranged obliquely, at this time, the test tube placed in placing seat 2 is also in inclined state, to meet the use demand of user for test tube inclined placement.

[0030] The bifurcated grooves 32 are arranged on both sides of the vertical groove 31 in actual application, and different included angles are arranged between the bifurcated grooves 32 and the vertical groove 31. Specifically, the angle difference between the bifurcated grooves 32 and the vertical groove 31 can be 5°-15°. The different included angles on both sides can realize the placement requirement of more inclined angles of the test tube and provide more use scenarios. In addition, the upper edge of the interface part between the vertical groove 31 and the bifurcated groove 32 is arranged as a rounded corner structure. The smooth rounded corner structure is more easily slid into the side bifurcated groove 32 when the limiting block 21 slides upward along the bottom of the vertical groove 31. The interface part between the bifurcated grooves 32 and the vertical groove 31 is staggered in vertical height. This staggered structure can make the bifurcated grooves 32 more distinct. The test tube is clamped into different bifurcated grooves 32 at different heights and is inclined at different angles.

[0031] In actual application, the bifurcated grooves 32 can also be arranged on the same side of the vertical groove 31, and more bifurcated grooves 32 with different angles are arranged to meet more placement requirements.

[0032] The limiting block 21 is clamped on the guide frame 3 through the clamping groove 24. This arrangement ensures the stability of the movement of the limiting block 21 along the clamping groove 24, avoids the deflection between the limiting block 21 and the guide frame 3, and also avoids the disengagement of the limiting block 21 from the guide frame 3.

[0033] The elastic assembly is composed of the sleeve 5 and the telescopic rod 51 inserted into the sleeve 5. One end of the telescopic rod 51 is connected to the sleeve 5 through a buffer spring, and the other end is sleeved on the spherical head 23 at the bottom of the placement seat 2 through the connecting sleeve 52. The placement seat 2 is connected to the connecting sleeve 52 through the nested structure of the spherical head 23 at the bottom. On the one hand, the nested structure can realize the free rotation of the spherical head 23 in the connecting sleeve 52, meeting the use requirement of the rotation of the placement seat 2. On the other hand, the nested structure is not easy to separate, which can avoid the disengagement between the placement seat 2 and the elastic assembly, so as to ensure that the placement seat 2 is always powered by the elastic force of the buffer spring in the elastic assembly, thereby ensuring the stable placement of the limiting block 21.

[0034] Two groups of clamping pieces 22 are arranged on the top of the placement seat 2 along the rim. The clamping pieces 22 can be arranged on both sides of the test tube after the test tube is placed into the placement seat 2. In addition, the middle part of the clamping piece 22 is recessed towards the center of the placement seat 2, so that the middle part of the clamping piece 22 is attached to the test tube, thereby clamping the test tube to ensure the stability after the test tube is placed. In addition, the top of the clamping piece 22 is provided with a trumpet-shaped flared structure. This flared structure has a guiding effect when the test tube is placed at the bottom, which facilitates the placement of the test tube and improves the work efficiency of the test tube placement.

[0035] The two opposite groups of clamping pieces 22 are between the two side guide frames 3, and the middle surfaces of the clamping pieces 22 coincide with the symmetry planes of the two side guide frames 3, and the clamping pieces 22 are in the rotating direction of the test tube when the test tube needs to be rotated and adjusted, so that the middle part of the test tube can be supported and a force point can be provided for the test tube, the test tube is prevented from being rotated only by the bottom against the placing seat 2, and the force burden of the bottom is reduced.

[0036] The base 1 is provided with the baffle 4 through the connecting rod 42, the limiting hole 41 on the baffle 4 is arranged directly above the placing seat 2, so that the test tube is in the limiting hole 41 after being placed in the placing seat 2, the upper half of the test tube is limited and protected through the limiting hole 41, and the test tube is prevented from being tilted and falling. The limiting hole 41 can be a waist-shaped hole, so that when the limiting block 21 is at the top end of the bifurcated groove 32, the test tube is tilted and just matches the end of the limiting hole 41, the test tube is supported through the limiting hole 41, and the stability of the test tube in the tilted state is ensured.

[0037] The technical scope of the utility model is not limited to the content in the above description, and the skilled in the art can make various deformations and modifications to the above embodiment without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the protection scope of the utility model.
