Abstract

The utility model relates to a test tube rack, and provides a tree-like test tube rack in order to solve the problems of less placed test tubes and large occupied space of the conventional test tube rack. The tree-like test tube rack is specialized by comprising a pedestal, a main shaft and a plurality of test tube brackets, wherein the main shaft is perpendicular to the pedestal; the test tube brackets can slide up and down along the main shaft; each test tube bracket comprises a transverse rod and a ring; one end of the transverse rod is connected with the outer edge of the ring, and the other end of the transverse rod is connected with the main shaft; and test tube nets with sealed bottoms are arranged below the ring. A plurality of layers of test tube brackets can be arranged on the main shaft, so that the number of placed test tubes is increased, and further the space is saved. The test tube brackets are adopted for placing the test tubes with the test tube nets, so that the mode of fixing the test tubes is changed; and when the test tubes are placed, a buffer effect is formed between the test tube nets, and the test tubes are not damaged even though the force of placing the test tubes is large.

Description

Tree-shaped rack for test tube

Technical field

The utility model relates to the rack for test tube that a kind of laboratory is used for placing test tube, relates in particular to a kind of tree-shaped rack for test tube.

Background technology

Rack for test tube is the basic experiment device that a kind of laboratory is used for placing test tube, is generally wooden shelf or bamboo shelf, and two kinds in 6 holes and 12 holes are arranged.Rack for test tube commonly used must be handled with care when placing test tube, otherwise the test tube bottom is damaged by contact-making surface easily; Simultaneously this rack for test tube be used for placing test tube negligible amounts, take bigger space.Though people have done many improvement to the rack for test tube of routine, still do not solve test tube and be prone to break, take problem than large space.

Summary of the invention

In order to solve negligible amounts, the bigger problem that takes up room that existing rack for test tube is placed test tube, the utility model provides a kind of tree-shaped rack for test tube.

The technical scheme of the utility model:

A kind of tree-shaped rack for test tube, its special feature be, comprises base, perpendicular to the main shaft of base and a plurality of test-tube stents that can slide up and down along main shaft, the connection for main shaft is rotated between main shaft and the base;

Said test-tube stent comprises cross bar and the circle that test tube is passed through; One end of cross bar is connected with the outer rim of circle, its other end is connected with main shaft; The circle below is provided with the test tube net of bottom seals.

The tree-shaped rack for test tube that the utility model provides, preferred, comprise also being used to connect main shaft and test-tube stent cross bar and retainer plate that can slide up and down along main shaft that retainer plate is provided with the flange that makes progress; One end of said cross bar is provided with the draw-in groove that can engage with flange.

The tree-shaped rack for test tube that the utility model provides, preferred, the length of the cross bar of said test-tube stent is unequal.

The tree-shaped rack for test tube that the utility model provides, preferred, the diameter of said main shaft from top to bottom increases gradually.

The beneficial effect of the utility model:

Be provided with a plurality of test-tube stents around main shaft; The height of being uneven in length of test-tube stent cross bar, test-tube stent can be regulated, and therefore the multilayer test-tube stent can be set; Increased and placed the quantity of test tube, and then practiced thrift the space.Test-tube stent adopts the test tube net to place test tube, has changed the fixedly mode of test tube; Placing test tube in time, there is cushioning effect between test tube net and the test tube, even the dynamics of placement test tube is bigger, can not damage test tube yet.

Description of drawings

Fig. 1 is the structural representation of tree-shaped rack for test tube;

Fig. 2 is the structural representation of the test-tube stent of tree-shaped rack for test tube;

Among the figure, 1. base, 2. main shaft, 3. test-tube stent, 4. retainer plate, 5. flange, 6. cross bar, 7. circle, 8 test tube net, 9. grooves.

The specific embodiment

Specify below in conjunction with Fig. 1 and 2 pairs of the utility model of accompanying drawing.

The tree-shaped rack for test tube that the utility model provides mainly is made up of base 1, main shaft 2, retainer plate 4 and test-tube stent 3.Main shaft 2 bottoms are vertically mounted on base 1 central authorities; Base 1 horizontal positioned, main shaft 2 can rotate.Retainer plate 4 is enclosed within on the main shaft 2 and can slides up and down along main shaft 2; Test-tube stent 3 is installed on the retainer plate 4, is connected mode for convenience detach between the two.

The outward flange of retainer plate 4 has flange 5 upwards, connects through flange 5 between retainer plate 4 and the test-tube stent 3.Test-tube stent 3 mainly comprises cross bar 6, circle 7 and test tube net 8; One end of cross bar 6 and the outward flange of circle 7 are fixed, and the other end is provided with groove 9 structures; The groove width of groove 9 and flange 5 adapt, and groove 9 engages with flange 5; Circle 7 is with test tube net 8, test tube net 8 bottom seals, employing soft materials.Wherein the somewhat larger in diameter of circle 7 is in the external diameter of test tube, and the degree of depth of test tube net 8 is 0.7 times a test tube length.

A plurality of retainer plates 4 that are positioned at differing heights can be set, and then multilayer test-tube stent 3 is installed; The test-tube stent 3 that cross bar 6 is uneven in length can be installed on the different fixed circle 4; Simultaneously can also according to place test tube the model difference adjust the position of retainer plate 4.

During use, directly test tube is placed on test tube net 8 interior getting final product, can rotating spindle 2 when picking and placeing test tube far away.
