Abstract
The invention discloses an electronic cradle used in a physical experiment and relates to the technical field of manufacturing of teaching aids. The electronic cradle comprises a cradle body, wherein a core body is mounted in the cradle body; a chamber for accommodating a battery is formed in the core body; a spring is arranged at the bottom of the chamber; a lamp holder communicated with the chamber through a guide body block is arranged at the top of the core body; a cradle lamp extending out of the cradle body is mounted on the lamp holder; the core body is connected with a base through a screw rod arranged at the bottom. Compared with the prior art, the electronic cradle disclosed by the invention can solve the problem that an existing light source used in the physical experiment is a cradle, is poor in stability and pollutes indoor air.
Description
Technical field
The present invention relates to teaching aid manufacturing technology field, especially a kind of for the electric candle in convex lens experiment and level crossing experiment.
Background technology
Convex lens experiment and level crossing experiment are important physical experiments in middle school teaching material, at present in teaching, for imaging clearly, be candle in convex lens experiment and the Physical Experiment such as level crossing experiment with light source used, use candle following not enough for light source exists: 1, because experiment will pull on curtain of classroom, the gas that candle combustion produces and the black smoke of emerging, can pollute room air; 2, candle candle flame is in atmosphere exposed, and be subject to airflow influence and rock, light source stability is poor, and the height of picture of cause lighting up flame and candle flame is not easy to measurement, the most clearly as position not easily determine; 3, the paraffin dropping in desktop and ground is difficult to cleaning.
Summary of the invention
Problem solved by the invention is to provide a kind of Physical Experiment electric candle, to solve existing Physical Experiment light source used for candle light source stability difference and the problem polluting room air.
In order to solve the problem, the technical solution used in the present invention is: this Physical Experiment electric candle includes candle body, at described candle body built with a core body, the chamber laying battery is provided with in described core body, spring is provided with in the bottom of described chamber, be provided with the lamp socket by conductor block and described chamber at the top of described core body, described lamp socket is equipped with the candle lamp stretching out described candle body; Be connected with base by the screw rod being located at bottom at described core body.
In above-mentioned Physical Experiment electric candle technical scheme, technical scheme can also be more specifically: be provided with battery cover at the sidewall of described core body.
Further: described candle lamp is red LED.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: owing to being LED as the candle lamp of light source, good many disadvantages of having avoided using candle as light source, and select people's naked eyes than more sensitive red light source, the picture that optical screen presents is clear especially, light source stability is good, and teaching demonstration is effective.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below in conjunction with attached Example, the invention will be further described:
Physical Experiment electric candle as shown in Figure 1 includes candle body 2, in candle body 2 inside, a core body 3 is housed, the chamber that one is laid battery 4 is had in core body 3, in the bottom of chamber, spring 5 is housed, lamp socket 3-2 by conductor block 3-1 and chamber is housed at the top of core body 3, lamp socket 3-2 is equipped with the candle lamp 1 stretching out candle body 2, and candle lamp 1 is red LED; Battery cover 9 is provided with at the sidewall of core body 3; A screw rod 6 is housed in the bottom of core body 3, and the two ends of screw rod 6 are all provided with one section of thread segment, and one end of the present embodiment screw rod 6 is first connected with core body 3 by screw thread, then core body 3 and screw rod 6 are welded and fixed; Screw rod 6 other end is provided with one section of reference column 6-1, and screw rod 6 is inserted on the pilot hole of base 7 by its reference column 6-1.
During work, battery cover 9 on the chamber first battery 4 being put into core body 3, starts power switch 8, and namely available Physical Experiment electric candle carries out convex lens experiment or level crossing experiment.
