Abstract
The utility model discloses a novel rack for test tube with backlight function, which comprises a rack body and a light source; the rack body is composed of a left vertical plate, a right vertical plate and a base plate for connecting the two bottoms; a supporting foot is vertically provided on the base plate facing the two side surfaces; and the supporting leg is provided with a long strip groove corresponding to the length; a light source case is connected to the long strip groove in clamp connection; the right side of the light source case is a backlight plate, and the back side is provided with a power supply box and a control switch; the backlight plate and the power supply case are connected to the control switch circuit for forming a closed-loop. A backlight plate with the light source is added on the rack for test tube for experiment observer to observe experiment phenomenon conveniently, thereby obtaining accurate experiment result with convenience and practicality; the utility model is especially suitable for use during chemical experiment, and simultaneously the rack for test tube can be used for placing droppers with increased practicality.
Description
Technical field
The utility model relates to a kind of rack for test tube with backlight, relates to teaching demonstration utensil field.
Background technology
At present; In the presentation process in chemistry teaching classroom; Teacher often uses test tube and does the demonstration of the chemical reaction characteristic of solution and demonstrate to the student; The important chemical reaction of a part mostly is accompanied by the reactant liquor change in color and judges its chemical reaction characteristic, and observation of students is got up and can be left deep impression, thereby convenient the reinforcement learnt.Because test tube clamp is a transparent material; When receiving the interference of surrounding environment color, teacher can get a blank sheet of paper usually and block rearward, so that the student can know the correct color of solution in vitro of seeing clearly; If when a plurality of test tubes or a plurality of change color; Can bring inconvenience to teacher, the time in classroom that waste is valuable reduces quality of instruction.In addition, existing rack for test tube is more single on function, the place of not depositing dropper mostly.
Summary of the invention
To the weak point of above-mentioned prior art, the utility model provides a kind of novel rack for test tube of the band backlight function with backlight, can effectively solve the problem that above-mentioned prior art exists.
To achieve these goals, the technical scheme of the utility model employing is: disclose a kind of novel rack for test tube with backlight function, it comprises support body and light-source box; Support body is by left riser, right riser and be connected both base plates of bottom and form, and said support body also is provided with the frame plate of being with the test tube hole between left riser and right riser, and relative two sides are provided with vertical with it stand-off on base plate; On stand-off, be provided with the rectangular groove corresponding with its length; Said light-source box is connected on the rectangular groove, and the front of light-source box is a backlight, and the back side is provided with power pack and gauge tap; Said backlight, power pack and gauge tap circuit are connected, and form the closed-loop path.
As preferably, the side of said frame plate is provided with the dropper draw-in groove of arc.
Compared with prior art, the beneficial effect that this utility model is brought is: this utility model is simple in structure, the convenient use; On the basis of rack for test tube, add the backlight that is provided with light source, can make experiment observer observation experiment phenomenon more easily, to obtain experimental result accurately; Convenient and practical; Use when being particluarly suitable for doing chemical experiment, this rack for test tube also can be used as frame to put dropper used simultaneously, has strengthened its practicality.
