Description

Technical Field

[0001] The utility model belongs to the field of test tube storage racks, and in particular relates to a test tube storage rack for testing. Background Art

[0002] In blood transfusion testing, a large number of test tubes need to be placed on a test tube rack, and the test tube rack is often a multi-row structure to improve utilization.

[0003] Chinese patent publication number CN214916346U discloses a test tube storage rack for blood transfusion testing. When placing or removing a test tube, the connection between the bottom of the retaining device and the outer frame is contacted. Under the pulling action of the elastic puller, the single-row rack moves upward, causing the rack to spring upward, making it easy to find and remove the test tube. In this way, when removing a test tube, it is less likely to collide with the test tube in the previous row.

[0004] However, in the above-mentioned test tube storage rack for blood transfusion testing, the height at which the single-row racks are moved upward by the elastic pulling member is fixed. When one single-row rack is pushed upward by the elastic pulling member, the test tubes on the single-row rack are more conspicuous. However, when two or more single-row racks are pushed upward by the elastic pulling member, the heights of the single-row racks moved upward are the same, resulting in the test tubes on the single-row racks in the middle and rear rows of the racks still not being conspicuous.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a test tube storage rack for testing.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A test tube storage rack for inspection comprises a test tube rack, wherein a plurality of support seats are vertically slidably fitted in the test tube rack, a single-row rack is provided on the upper side of the support seats, two sliding seats are elastically fitted facing each other in the support seats, two limit pins are elastically slidably fitted in the sliding seats, a plurality of positioning grooves corresponding to the limit pins are provided on the inner wall of the test tube rack along the height direction, a first extrusion inclined surface is provided on the upper side of one end of the limit pin close to the positioning groove, a second extrusion inclined surface is provided on the lower side of one end of the limit pin close to the positioning groove, and an angle between the first extrusion inclined surface and the horizontal plane is smaller than an angle between the second extrusion inclined surface and the horizontal plane.

[0009] Optionally, the inner walls of the test tube rack are provided with guide grooves corresponding to the support seat, and the support seat is provided with guide protrusions on both sides, which are slidably fitted in the guide grooves.

[0010] Optionally, an open slideway is provided on one side of the sliding seat, the sliding seat slides in the open slideway, two limit blocks corresponding to the sliding seat are provided in the open slideway, and a first spring is provided between the two sliding seats.

[0011] Optionally, a through hole corresponding to the open slideway is provided on one side of the guide protrusion, and a handle connected to the sliding seat is slidably fitted in the through hole.

[0012] Optionally, a mounting groove corresponding to the limit pin is provided on one side of the sliding seat, one end of the limit pin is slidably fitted in the mounting groove, and a second spring connected to the limit pin is provided on the inner wall of the mounting groove.

[0013] Optionally, limiting plates are provided on opposite sides of the test tube rack, and the limiting plates correspond to the handles.

[0014] Optionally, the single-row rack includes a support bar arranged on the guide protrusion, two test tube limiting plates arranged between the two support bars, a plurality of sockets are provided on the upper side of the test tube limiting plates, and a rubber pad is provided on the upper side of the sliding seat.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0016] When the height of the single-row rack needs to be adjusted, the sliding seat is pulled up to drive the support seat to move upward, and the limit pin is squeezed by the first extrusion slope to slide elastically, the positioning slot is switched, and the plane of the bottom surface of the limit pin supports the limit pin, thereby supporting the single-row rack, which is convenient for quickly adjusting the height of the single-row rack. By providing a plurality of positioning slots corresponding to the limit pin, it is convenient to adjust the different heights of multiple single-row racks, so that multiple single-row racks in the test tube rack are in a stepped shape, which is convenient for adjusting multiple single-row racks. When the multiple single-row racks are raised, the test tubes on the multiple single-row racks are more eye-catching, which is convenient for taking the test tubes. By pressing the sliding seat to slide, the plane side of the bottom surface of the limit pin slides out of the positioning slot, and the limit pin is squeezed by the second extrusion slope to slide elastically, and the positioning slot is switched, which is convenient for downward adjustment of the support seat and the single-row rack, thereby improving the convenience of adjusting the height of the support seat and the single-row rack.
