Abstract
The utility model relates to a test tube rack, in particular to a light background type test tube rack. In order to solve the problems that when the color of a solution in a test tube is observed, the observation results are affected by the intensity of ambient light, the utility model provides the light background type test tube rack. A white light emitting device is arranged on the back surface of a test tube rack body without a baffle and comprises a rectangular box body and a lamp holder, a fluorescent lamp and a ballast which are arranged in the box body, and one side of the box body is provided with a light opening of which the shape is the same as that of the back of the test tube rack body; and the test tube rack body is butted to the light opening through the back of the test rack body. The white light emitting device emits white light which is irradiated on the test tube on the test tube rack body, thereby ensuring that the test tube is always positioned in a bright environment. Therefore, no matter how the intensity of light where the test tube is positioned is, and no matter where an observer is positioned, the observer can obviously and clearly observe the color of the solution in the test tube.
Description
Technical field
The utility model relates to a kind of rack for test tube, relates in particular to a kind of smooth background formula rack for test tube.
Background technology
Differentiate by observing the color of the solution that the composition of contained ion is that one of method " identifies and differentiate " to the material of commonly using in the solution; Observing simultaneously and differentiating the color of the solution also is one of basic training of chemical experiment.There are two problems when classmates observe in teacher's lecture experiment in vitro the color of the solution on the chemistry classroom: 1. the classmate who is sitting in diverse location, viewed the color of the solution has difference, and the solution colour difference that especially front-seat classmate and rear row classmate observe in the classroom is larger.2. same solution was observed respectively when fine and cloudy day, and the color of the solution that classmates observe is different.Through evidence, the test tube that color solution is housed is placed into well-lighted local the observation, the result is, is identical even be positioned at the result that the diverse location classmates observe.But, in daily teaching or test, can not guarantee that all be sun-drenched fine day every day, and test tube is moved to the thing that well-lighted place also is a trouble.
Summary of the invention
When observing in vitro solution colour in order to solve, the power of extraneous light can affect the problem of observed result, and the utility model provides a kind of smooth background formula rack for test tube.
The technical solution of the utility model:
A kind of smooth background formula rack for test tube comprises the rack for test tube body that the back side is not baffled, and its special feature is, the rack for test tube body back side is provided with the device that emits white light.The device that emits white light can emit beam, and is radiated on the test tube on the rack for test tube body, thereby guarantees that the test tube on the rack for test tube body is in the well-lighted environment all the time.
Above-mentioned light background formula rack for test tube, preferred, the described device that emits white light comprises: cuboid casing and be located at lamp socket, fluorescent lamp, ballast in the casing; A wherein side of casing has the light mouth identical with rack for test tube body back side shape, and the rack for test tube body docks with the light mouth by its back side.Wherein, the position of fluorescent lamp is not specifically limited, and can regulate according to the size of casing, rack for test tube body.Fluorescent lamp is arranged in the casing, and casing only has a light mouth, thus light not can to around scattering, and can only be radiated on the test tube by the light mouth; Thereby guaranteed to have sufficient light to be radiated on the test tube and saved the energy.
Above-mentioned light background formula rack for test tube is characterized in that, described casing, and the inboard on other surfaces except the two sides adjacent with the light mouth is compounded with reflective membrane; Described casing light mouth covers with the frosted plastic foil.Reflective membrane is that the frosted plastic foil is in order to make light generation scattering, to make light become even for further the minimizing interior is to the absorption of light.The light that fluorescent lamp sends can make light be radiated on the test tube uniformly by the mirror-reflection of reflective membrane and the scattering of frosted plastic foil.
Above-mentioned light background formula rack for test tube shuts out the light in order to prevent the rack for test tube body, and described rack for test tube body is made by transparent material; Even in order to make through the light after the reflective membrane reflection, the inner surface turning of described casing is arc.
Above-mentioned light background formula rack for test tube all can be shone by the light that the device that emits white light emits in order to make all test tubes on the rack for test tube body, and the length of described case is greater than the length of pipe support body, its height height greater than the rack for test tube body.
The beneficial effects of the utility model:
The light that the device that emits white light in casing emits is radiated on the test tube of rack for test tube body, thereby test tube is in the white light near natural daylight; Therefore, no matter the light in the classroom that is positioned at of rack for test tube body how, where be in the classroom position regardless of the observer, the observer can both obviously, clearly observe in vitro the color of the solution; Eliminated extraneous light to the impact of observed result.Use the utility model also can clearly observe in vitro state, the color of suspension, precipitation.When ocular estimate check medicine, use the utility model also can obtain good effect.
Description of drawings
Fig. 1 is the structural representation of light background formula rack for test tube;
Among the figure, 1. rack for test tube body, 2. casing, 3. light mouth, 4. lamp socket, 5. ballast, 6. fluorescent lamp, 8. dividing plate, 9. supporting plate.
The specific embodiment
Further specify below in conjunction with accompanying drawing.
Smooth background formula rack for test tube of the present utility model, mainly emit white light device and rack for test tube body 1 consist of.The device that emits white light is the cuboid casing 2 of establishing lamp socket 4, ballast 5, fluorescent lamp 6 in one, have light mouth 3 on one of them side, the shape of light mouth 3 overlaps with the bottom surface of casing 2 with the shape at rack for test tube body 1 back side lower limb identical and light mouth 3, the top edge of light mouth 3 overlaps with the upper surface of casing 2.Rack for test tube body 1 is made by transparent plastic, comprises two dividing plates 8 and supporting plate 9, is furnished with pore on the dividing plate 8, supporting plate 9 be positioned at rack for test tube body 1 the bottom, play a supportive role; But its back side is not baffled.Rack for test tube body 1 docks with light mouth 3 on the casing 2 by its back side, and namely the supporting plate 9 of the bottom surface of casing 2 and rack for test tube body 1 joins, and the dividing plate 8 above being positioned at of the upper surface of casing 2 and rack for test tube body 1 joins.
One of them side adjacent with light mouth 3 of casing 2 is provided with installs ballast 5 on lamp socket 4, the another side, fluorescent lamp 6 is installed on the lamp socket 4.
