Abstract
The invention discloses a test tube rack. The test tube rack comprises a bottom plate, wherein upper support rods are symmetrically arranged at the two ends on the top surface of the bottom plate in the length direction of the bottom plate; horizontal plates are fixed at the tops of the upper support rods; test tube insertion holes are formed in the horizontal plates; circular holes which have smaller diameters than the test tube insertion holes and correspond to the test tube insertion holes are formed in the bottom plate; support plates are arranged on the two sides of the bottom surface of the bottom plate respectively along the length direction of the bottom plate; a water receiving sink is connected on the support plates in a sliding manner. Test tubes are inserted into the test tube insertion holes or are placed on sleeve rods upside down, water on the walls of the test tubes flows to the bottom plate along the test tubes and then flows into the water receiving sink via the circular holes or drain holes, and then users only need to pour the water in the water receiving sink away periodically, thus effectively preventing the water on the test tubes from flowing to a table top and wetting the table top.
Description
Technical field
The present invention relates to a kind of rack for test tube.
Background technology
Rack for test tube is the most basic laboratory apparatus of chemical laboratory, needs test tube to be placed on rack for test tube and to deposit before experiment, in experimentation, often test tube is placed on to observation experiment phenomenon on rack for test tube, also needs the test tube of cleaning to be placed on rack for test tube and to dry.During existing rack for test tube holding test tubes, the water carrying on test tube can be got desktop wet, affects the normal use of desktop.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of rack for test tube.
For solving the problems of the technologies described above, the present invention includes base plate, the end face of described base plate is arranged with upper support bar at the two ends of its length direction, described upper support bar top is fixed with level board, described level board is provided with test tube plug-in opening, and the corresponding test tube plug-in opening of described base plate is provided with the circular hole that diameter is less than test tube plug-in opening; Described base plate is respectively equipped with gripper shoe in the both sides of its bottom surface along its length, in described gripper shoe, slidably connects water receiving tank.
The inner surface of described two gripper shoes is arranged with slideway, and the both sides at described water receiving tank top are respectively equipped with engaging lug overhanging and that adapt with slideway.
Described upper support bar is two groups, and the height of two groups of upper support bars is different.
The end face of described base plate is provided with the loop bar that many its maximum outside diameters are less than test tube internal diameter, and described loop bar sets in a row.
The external diameter of described loop bar reduces from bottom to top gradually, and its top is sphere.
Described base plate is provided with annular groove on the week edge of loop bar bottom, and described annular groove place is provided with leaking hole.
Adopt after said structure, test tube is inserted to test tube plug-in opening or tips upside down on loop bar, water on test tube wall flow to base plate along test tube, then from circular hole or leaking hole, flow in water receiving tank, user of service only needs regularly the water in water receiving tank to be outwelled, and effectively avoids water on test tube to flow to desktop desktop is got wet.
Accompanying drawing explanation
Below in conjunction with the drawings and the specific embodiments, the present invention is described in further detail:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation that Fig. 1 analyses and observe along A-A line.
The specific embodiment
As depicted in figs. 1 and 2, rack for test tube comprises base plate 1, and the end face of base plate 1 is arranged with the height of 2, two groups of upper support bars 2 of two groups of upper support bars at the two ends of its length direction different, and upper support bar 2 height of rear side are higher than the upper support bar 2 of front side.Every group of upper support bar 2 tops are fixed with level board 3, level board 3 is evenly equipped with a plurality of test tube plug-in openings 4 along its length, the diameter that is positioned at the test tube plug-in opening 4 of offering on the level board 3 of rear side is greater than the diameter of the test tube plug-in opening 4 of offering on the level board 3 of front side, the corresponding test tube plug-in opening 4 of base plate 1 is provided with the circular hole 5 that diameter is less than test tube plug-in opening 4, and circular hole 5 and test tube plug-in opening 4 are positioned on same vertical axis.The end face of base plate 1 is provided with the loop bar 6 that many its maximum outside diameters are less than test tube internal diameter, and loop bar 6 sets in a row.The external diameter of loop bar 6 reduces from bottom to top gradually, and its top is sphere.Base plate 1 is provided with annular groove 7 on the week edge of loop bar 6 bottoms, and described annular groove 7 places are provided with leaking hole 8.
This rack for test tube is made by the synthetic resin single injection-molded with good heat resistance, chemical-resistant.
