Based on technique scheme, be all equidistantly provided with three elasticity spacers at each test tube open holes place, each spacer end all has draw-in groove.
The beneficial effects of the utility model: the utility model designs for test tube microbial culture specially, handle rotary handle, the light rotation of test tube dish can be realized, and locating structure easy and simple to handle is equipped with, press down position fixing handle, chuck engages with gear tooth slot, and test tube dish can be fixed on specific position, the test tube be positioned on test tube dish can unify inclination certain angle, easily realizes inclined-plane microbial culture.This swivel mount global design structure is simple, and low cost of manufacture, it is extremely convenient to operate, and good stability is highly suitable for field of medicaments particularly teaching field promotion and implementation.
Accompanying drawing explanation
Fig. 1 is one of the utility model test tube rotary positioning frame structural representation;
Fig. 2 is the utility model test tube rotary positioning frame structural representation two.
Number in the figure, 1 is support, and 2 is test tube dish, and 3 is rotating shaft, and 4 is gear, and 5 is position fixing handle; 6 is chuck, and 7 is rotary handle, and 8 is open holes, and 9 is flexure strip, and 10 is elasticity spacer, and 11 is curved support plate, and 12 is bearing pin.
Embodiment
Below in conjunction with embodiment, the utility model is described further, better to understand technical solutions of the utility model.
Embodiment 1: a kind of test tube rotary positioning frame, see Fig. 1, comprising support described in two symmetrical supports 1 placed is arc frame, frame bottom two supporting legs in falling the design of " v " font, to improve the stability that bottom leg supports.On two stands 1, correspondence position arranges an axis hole respectively, runs through two axis holes and is provided with rotating shaft, be fixedly installed test tube dish 2 in the middle part of rotating shaft, and described test tube dish 2 is provided with some test tube open holess 8, and described test tube open holes 8 is equidistantly evenly arranged on test tube dish.Described rotating shaft and test tube dish are structure as a whole.The size of pivot design and hardness are enough large, are enough to support all test tubes placed, and ensure the stationarity that test tube is placed.Open holes quantity can be 15 shown in Fig. 1, also as required, can arrange the open holes of greater amt.All equidistantly be provided with three elasticity spacers 10 at each test tube open holes place, each spacer 10 end all has draw-in groove.Test tube is positioned over open holes place, and spacer draw-in groove is fastened on test tube circumference, plays good positioning action to test tube, prevents test tube from placing unstable.
End, described rotating shaft one end is provided with rotary handle 7, the other end end winding support is provided with gear 4, with gear 4 the same side support on be provided with bearing pin, bearing pin is provided with position fixing handle 5, between the support and position fixing handle on position fixing handle top, is being provided with stage clip.Position fixing handle can rotate arbitrarily around bearing pin.Described position fixing handle 5 is provided with chuck 6 with gear 4 correspondence position, described chuck 6 and gear tooth slot snap-fit.
In order to improve the stability of position fixing handle, position fixing handle 5 and bearing pin installation place are provided with damping structure.And with one deck friction materials in gear tooth slot, increase the sticking power of chuck and teeth groove, ensure the tight type that chuck engages with teeth groove further.In order to locate better, described position fixing handle be provided with threaded hole, and be equipped with the set screw nut mated with threaded hole.
The present embodiment test tube rotary positioning frame operates extremely easy in use, be specially: the test tube installing a certain amount of substratum is placed on successively in test tube dish open holes, during placement, test tube is through flexure strip, the flexure strip end lucky clamping stagnation of draw-in groove is at test tube circumference, good clamping action is played to test tube, after test tube is placed, manual operation rotary handle, rotating shaft drives test tube dish to rotate, the each test tube be positioned on test tube dish swings certain angle thereupon, after tilting to specified degree, move position fixing handle downwards, handle chuck engages with gear tooth slot, it is motionless that test tube dish tilts to specific position, now, in order to ensure the stationarity that long-time test tube is placed, set screw nut inserts threaded hole, position fixing handle is held out against to support.By operation the present embodiment rotary positioning frame, the unified slant setting of multiple test tube can be realized while batch, ensure that the consistence at all test tube angles of inclination, easily realize the inclined-plane microbial culture of test tube, schedule of operation simplifies, and improves conventional efficient, is convenient to teacher and easily imparts knowledge to students.
