Abstract
It the utility model is related to a kind of compass case for caning be assembled into teaching set square, including lid plate（1）, box back side panel（2）, box front side board（3）And box body（4）, belong to teaching equipment technical field.Lid plate, box back side panel and the box front side board of the compass case, as the three of set square side, during teaching, three sides are assembled into teaching set square by dovetail groove, and after the completion of teaching, compass case is assembled into by the dovetail groove on three sides and box body.The beneficial effects of the utility model are：Teaching set square or compass case can be assembled into respectively by dismounting, that is, the picture function of set square when realizing teaching, protection compasses determine pin and dynamic pin when having haveed the function that to carry again, and it is compact-sized, dismount it is easy and easy to carry.
Description
Technical field
A kind of compass case for caning be assembled into teaching set square of the utility model, belongs to educational aid, and in particular to teaching
Equipment technical field.
Background technology
In the teaching of some courses such as mathematics and Graphing of Engineering, set square and compasses are substantially the indispensable teaching work of teacher
Tool, conventional use of teaching set square space-consuming is larger on the market, very inconvenient during carrying, and the calipers function of teaching ratio
It is more single, and if in carrying process without the protection of compass case when, it determines pin and dynamic pin easily fractures or damaged.
The content of the invention
For above-mentioned problem and deficiency of the prior art, patent applicant is designed improvement, has invented one
Kind can be assembled into the compass case of teaching set square, can be assembled into teaching set square or compass case respectively by dismounting, that is, realize
The picture function of set square during teaching, compass case protection compasses determine pin and dynamic pin when having haveed the function that to carry again, and with knot
Structure is compact, dismounting is easy and it is easy to carry the features such as.
The utility model is achieved through the following technical solutions：
1st, a kind of compass case for caning be assembled into teaching set square of the utility model, by lid plate, box back side panel, box front side board
Formed with box body.
2nd, a kind of compass case for caning be assembled into teaching set square of the utility model, it is not change the base of former teaching set square
On plinth, realized by changing the assembling mode on existing three sides of set square for teaching.
3rd, a kind of compass case for caning be assembled into teaching set square of the utility model, by the scale side of former set square（That is lid
Plate）Inner side processes dovetail groove groove, and dovetail groove groove effect one is the neck on another two sides of installation set square, acts on two
Neck during to be assembled with compasses box body, as shown in Figure 2.
4th, a kind of compass case for caning be assembled into teaching set square of the utility model, by a right-angle side of former set square（I.e.
Box back side panel）Both ends process dovetail groove tongue, another right-angle side（That is box front side board）One end processes dovetail groove tongue, separately
One end processes dovetail groove groove, as shown in Figure 2.
5th, a kind of compass case for caning be assembled into teaching set square of the utility model, leave room on box body biside plate for pacifying
Mounted box front side board and box back side panel, and dovetail groove groove and tongue are processed respectively in box body front side board relevant position, in rear side
Plate relevant position processes dovetail groove groove, and box body foreboard inside top processes dovetail groove tongue, as shown in Figure 2.
6th, a kind of beneficial effect for the compass case for caning be assembled into teaching set square of the utility model is：Carried out by dovetail groove
Assembling, dismounting and carries convenient and compact-sized, is assembled into set square during teaching, is then assembled into justifying after pulling down during carrying
Advise box, the protection calipers function of picture and compass case with set square.
Brief description of the drawings
Fig. 1 is axonometric drawing when the utility model is assembled into compass case
Fig. 2 is the axonometric drawing of each component after the utility model is split
Fig. 3 is front view when the utility model is assembled into set square
In figure：1. the box body of 2. box back side panel of lid plate, 3. box front side board 4..
Embodiment
To illustrate a kind of technical scheme for the compass case for caning be assembled into teaching set square of the utility model, with reference to
The drawings and specific embodiments are described in detail：
Fig. 2 show a kind of compass case exploded view for caning be assembled into teaching set square of the utility model, and use is more straight
The axonometric drawing of sight represents, in figure 1,2,3 be compass case lid plate, box back side panel and box front side board, i.e. the three of set square side,
They can assemble isoceles triangle plate at a right angle in teaching process and use, and also can individually do ruler use, or assembling
Used into one piece of square and ruler, in figure 4 be compass case box body, for containing compasses, protection compasses move pin and fixed
Pin.
Fig. 3 show front view when set square is completed, after teacher enters classroom, first by lid plate, box back side panel
Extracted out with box front side board, then the dovetail groove tongue of box back side panel and box front side board dovetail groove groove are installed, finally again by both sides
Plate tongue push-in lid plate groove, complete the assembling of set square, its profile with function as general teaching set square,
It is ready for setting-out in teaching process.
More intuitively to express compass case, axonometric drawing is used when compass case is completed, as shown in Figure 1, after the completion of teaching,
First compasses are put into box, then set square is pulled down, box back side panel and box front side board are inserted into compass case box body by dovetail groove
Assemble, the dovetail groove tongue that last lid plate is processed by box body front side board inside top installs box, and teacher can be straight
Catcher holds box body, is easy to carry.
The compass case can be made using timber, duroplasts or high polymer material etc., and can be as needed, make various rule
Lattice.
