Abstract
The utility model discloses a plug-in groove type circuit teaching display board, which is composed of a main board and a plug-in board. As for the main board, a plurality of parallel rebbet strip-shaped boards are fixed on a base board. A groove with an upward opening is formed between each strip-shaped board and the base board. The top side and the bottom side of the plug-in board are plug-in pieces. After the plug-in board is fixed on an experiment instrument, the experiment instrument can be plugged and hung on the main board for display use. The teaching display board with low cost and visual display can utilize the existing teaching instruments to do all experiments in middle school physics, and is suitable for general middle school physics teaching.
Description
The utility model relates to a kind of teaching aid, is a kind of insertion slot type circuit demonstrator specifically.
The demonstrator that present middle school physical experiment is used has plug-in type circuit brassboard, and its principal feature is that the phosphor-copper spring leaf between the adjacent elements just touches together after being inserted into member block on the plug-in card, save lead, but plug is inconvenient during operation, and existing teaching equipment is not used, and cost is higher.
The purpose of this utility model is to overcome the shortcoming of existing brassboard, provides a kind of cost low, easy to use, and demonstrating visual also can utilize the insertion slot type circuit demonstrator that has experiment equipment now.
Demonstrator of the present utility model is made up of mainboard and plug-in card, and mainboard is a bar andante of fixing many rabbets that are parallel to each other on base plate, forms the narrow groove that opening together makes progress between bar andante and the base plate; Plug-in card is a thin plate, and both sides are respectively inserted sheet up and down, and two inserted sheets can insert respectively in the groove of two andante upward openings.After plug-in card and certain experiment are fixed with equipment, just can plug in the equipment of experiment usefulness to hang over and make demonstration usefulness on the mainboard.
Advantage of the present utility model is simple in structure, and is easy to use, and demonstrating visual can utilize the current experiments equipment to finish all lecture experiments of physics teaching in secondary school.
Fig. 1 is the synoptic diagram of the utility model mainboard;
Fig. 2 is the synoptic diagram of the utility model plug-in card;
Fig. 3 is the utility model user mode synoptic diagram.
The utility model is described in further detail below in conjunction with embodiment.
Fig. 1 is the mainboard synoptic diagram, and base plate (1) is gone up nail the pentahapto stripe board (2) that is parallel to each other, the first half by base plate one side of each bar andante cut out go two-layer, make it and base plate between constitute the groove (3) that an opening makes progress.
Fig. 2 is the plug-in card synoptic diagram, and there is metal insert (4) on the both sides up and down of plug-in card (5), and (6) are the securing member perforation of fixedlying connected with experiment equipment, also can bond with experiment equipment.
Fig. 3 is the utility model user mode, 4 plug-in cards self-contained battery respectively close (8), two switches (9) (10), one amp gauge (11), then two inserted sheets up and down (4) of plug-in card are inserted respectively in the groove (3) of two bar andantes (2), the demonstration equipment is just inserted and has been hung on the mainboard like this, and (12) are lead, (7) amp gauge reading dial for amplifying.This experiment is for surveying the strength of current experiment with amp gauge.This demonstration board can be inserted and hang a plurality of demonstration equipment, can demonstrate all lecture experiments of physics teaching in secondary school.
Claims (1)
