fig. 2 is a schematic view of the placing board a and the placing board B when they are turned upside down;
in the figure: 1-placing plate A, 2-placing plate B, 3-supporting rod, 4-fume hood, 5-back plate, 6-connecting block, 7-supporting block, 8-magnet, 9-iron sheet and 10-negative pressure air pipe.
Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1 and 2, the holding rack for the test fume hood comprises a holding plate a1, a holding plate B2, a supporting rod 3 and a fume hood 4, wherein a back plate 5 is arranged on the fume hood 4, one ends of the holding plate a1 and the holding plate B2 are connected with the back plate 5 through connecting blocks 6, one end of each connecting block 6 is connected with the holding plate a1 and the holding plate B2 through rotating shafts, the other end of each connecting block is fixedly connected with the back plate 5, the number of the supporting rods 3 is two, the upper portion of each supporting rod 3 is hinged to two sides of the holding plate a1, the lower portion of each supporting rod 3 is hinged to two sides of the holding plate B2, the length and the width of the holding plate a1 and the width of the holding plate B2 are the same, the holding plate a1 and the holding plate B2 are parallel, and the supporting rods 3 and the back plate 5 are parallel.
When needs expand the rack, will place board A1 and outwards draw, make iron sheet 9 and magnet 8 separation, under bracing piece 3 drives, place board A1 and place board B2 and overturn simultaneously, when placing board A1 and place board B2 and reach horizontal angle, bracing piece 3 lower part just in time leans on supporting shoe 7, provide the holding power through supporting shoe 7, the messenger places board A1 and places board B2 and keep the level, operating personnel can place articles for use such as medicine on placing board A and placing board B during the experiment, thereby space utilization on the test bench has been improved, the operating personnel of being convenient for carry out the experiment.
