Abstract
The utility model discloses a cleaning device for test tubes, and relates to the field of laboratory appliances. The cleaning device for the test tubes comprises a groove and a base plate, wherein a round hole is formed in the bottom of the groove; the round hole is conical; the lower hole diameter of the round hole is bigger than the diameter of a test tube mouth; the upper hole diameter of the round hole is smaller than the diameter of the test tube mouth; the inner side of the side wall of the groove is inclined upwards; the base plate is arranged at the bottom of the groove; and an antiskid layer is arranged on the upper surface of the base plate. The cleaning device for the test tubes has the beneficial effects of being reasonable in structure, convenient and practical, low in cost, and in favor of popularizing.
Description
Technical field
The utility model relates to experiment apparatus field, relates in particular to a kind of test tube cleaning device.
Background technology
In biology and chemical laboratory operating process, in order to satisfy test requirements document, often relate to the flushing of test tube, its operating procedure is: uncap, water filling, capping plug, put upside down mixing, repeat this step 3-5 time.The cleaning device automaticity of a great variety of present test tube is also than higher, but the instrument price is higher and need periodic maintenance, and it is lower that the laboratory is equipped with popularity.At present, the laboratory generally adopts the manual water that adds to wash test tube, and the flushing of test tube in enormous quantities will be loaded down with trivial details and require great effort operation of testing crew, not only will each test tube be operated separately, waste time and energy, and manual operations also easily bring pollution.Therefore need a kind of test tube of invention to clean servicing unit to overcome the problems referred to above.
The utility model content
The utility model provides a kind of test tube cleaning device at the prior art above shortcomings, and by being provided with circular hole at bottom portion of groove, the mouth of pipe aperture of having a competition, aperture is big under the circular hole, and the mouth of pipe aperture of having a competition, last aperture is little, can adapt to the demand of different-diameter test tube.Be inclined upwardly by the recess sidewall inboard, can make liquid flow to the bottom.By being provided with backing plate at bottom portion of groove, can conveniently seal circular hole.Accomplish easy to usely, realize batch operation, save experimental water.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of test tube cleaning device, comprise groove, backing plate, described bottom portion of groove is provided with circular hole, it is conical that described circular hole is, the mouth of pipe aperture of having a competition, aperture is big under the described circular hole, and the mouth of pipe aperture of having a competition, aperture is little on the described circular hole, and described recess sidewall inboard is inclined upwardly, described bottom portion of groove is provided with backing plate, and described backing plate upper surface is provided with skid resistant course.
Described bottom portion of groove is made by rubber, and described recess sidewall is made of plastics, and described backing plate is made of plastics.
Described circular hole is provided with 9-64.
Described circular hole is provided with 20.
Utility model beneficial effect: rational in infrastructure, convenient and practical, cost is low, be beneficial to popularization, easy operating becomes multiple to simplify the repeated operation step, can be easily in experimentation with plastics groove bottom outlet one by one correspondence add a cover again on the test tube, the design of backing plate has simultaneously realized that test tube can put upside down the purpose of mixing, has further strengthened developing result.
Description of drawings
Fig. 1 is a kind of test tube cleaning device structural representation described in the utility model:
Among the figure: the 1-groove; The 2-backing plate; The 3-circular hole; The 4-sidewall; The 5-handle.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
A kind of test tube cleaning device, comprise groove 1, backing plate 2, described groove 1 bottom is made by rubber, described groove 1 bottom is provided with circular hole 3, it is conical that described circular hole 3 is, the mouth of pipe aperture of having a competition, 3 times apertures of described circular hole is big, the mouth of pipe aperture of having a competition, aperture is little on the described circular hole 3, because groove 1 bottom made by rubber, so circular hole 3 has elasticity, conical circular hole 3 can adapt to the demand of different-diameter test tube, the various test tubes in laboratory all can be inserted on the test tube mouth smoothly, and convenient fixing back is cleaned, and described groove 1 sidewall 4 is made of plastics, can guarantee the flintiness of groove 1, described groove 1 sidewall 4 inboards are inclined upwardly, and can make liquid flow to the bottom, prevent ponding and residual, recess sidewall 4 is provided with handle 5, is used for fixing device and rack for test tube; Described groove 1 bottom is combined with backing plate 2, and the area of plastic base plate 2 is identical with groove 1 bottom, and described backing plate 2 is made of plastics, and can conveniently seal above circular hole 3, and described backing plate upper surface is provided with skid resistant course.Can increase frictional force, prevent that hand from skidding, the quantity of circular hole 3 and arranged distribution and number are corresponding one by one with test tube number of perforations on the rack for test tube; General described circular hole 3 is provided with that 9-64 is comparatively suitable, and preferred plan is that circular hole is provided with 20, is complementary with test tube quantity on the existing rack for test tube.
When the flushing operation of test tube in enormous quantities, only need the bottom surface of groove 1 is placed on the test tube of rack for test tube, make the tight-lipped close combination of each hole and test tube, be filled to the suitable height of test tube in the groove 1, subsequently plastic base plate 2 is placed groove 1 bottom, and with hand the handle of groove 1 both sides and rack for test tube are fixed together and shake and put upside down the mixing operation.At last, again groove 1 is just being placed test tube top, plastic base plate 2 is taken off, with hand fixedly rack for test tube and groove 1, inversion makes the water outflow, thereby finishes flushing operation.The aforesaid operations step is easy, quick, has improved the efficient of test tube flushing greatly, and can effectively prevent artificial pollution.
