In order to solve the above-mentioned technical problem, the technical solution adopted is as follows:
A kind of scalable set square, it is characterised in that including first it is flexible while, second it is flexible while and third stretch side, respectively stretch
The end of cissing is connected by a hinge the corresponding end in adjacent expansion side respectively；First it is flexible while, second it is flexible while and third stretch
Cissing includes fixed section and telescopic segment, and each fixed section all has the U-shaped sliding slot extended along its length, U-shaped sliding slot
It is opened on the medial surface of fixed section, each telescopic segment is respectively in corresponding U-shaped sliding slot and is slidably matched with U-shaped sliding slot, respectively stretches
The medial surface of contracting section is in same plane with the medial surface of corresponding fixed section, and the side wall of each U-shaped sliding slot is equipped at least one spiral shell
Hole, lock-screw is equipped in screw hole, and lock-screw end and telescopic segment are in close contact.
In above structure, first it is flexible while, second it is flexible while and third stretch side fixed section all have along its length side
To the U-shaped sliding slot of extension, each telescopic segment is in corresponding U-shaped sliding slot and is slidably matched with U-shaped sliding slot, so that the three of set square
The length on side and the angle of three interior angles can be adjusted freely as needed, complete set square three edge lengths and three
After the angular adjustment of angle, each lock-screw is screwed, it can fixed triangle ruler shape.Since the medial surface of each telescopic segment is fixed with corresponding
The medial surface of section is in same plane, and when drawing triangle using set square, three sides and three interior angles can smoothly be drawn
It produces and, form complete triangle.
As a preferred embodiment of the present invention, each fixed section and telescopic segment are carved with length scale.Flexible side
Fixed section and telescopic segment are carved with length scale, convenient for adjusting the length on flexible side as needed.
As a preferred embodiment of the present invention, the guiding extended along its length is equipped in each telescopic segment
Slot is set on the side wall of the U-shaped sliding slot of fixed section there are two screw hole, and the end for being mounted on the lock-screw in the two screw holes is embedding
Enter in guide channel.Pass through the cooperation of guide channel and two lock-screws, it can be ensured that during adjusting flexible edge lengths, stretch
Duan Buhui dislocation.When needing to adjust the length on flexible side, lock-screw is first slightly unclamped, lock-screw end is made to be detached from guide channel
Slot bottom but still be in the cavity of guide channel, telescopic segment is then moved to required position, then screw lock-screw, makes locking screw
Guide channel slot bottom is withstood in nail end, and the position of telescopic segment is fixed.
As a preferred embodiment of the present invention, the scalable set square further includes protractor, and protractor is dismountable
It is mounted on any one vertex of set square.Apex is arranged dismountable protractor and is convenient for adjusting triangle ruler interior angle as needed
Size, after set square shape is fixed, removing protractor would not influence to be drawn using set square.
The beneficial effect of the utility model against existing technologies is: this scalable set square, structure is simple, cost
Lower, practical, three sides of set square can change length by adjusting, and form various interior angles, side length is all different
Set square, draw triangle when, three sides and three interior angles can smoothly be drawn out.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of scalable set square in the utility model embodiment；
Fig. 2 is cross-sectional view of the Fig. 1 along the direction A.
Specific embodiment
The utility model is further described in the following with reference to the drawings and specific embodiments:
A kind of scalable set square as shown in Figs. 1-2, including the flexible side 3 of the first flexible 2, third when 1, second is flexible
With protractor 4, it is each it is flexible while end pass through corresponding end when hinge 5 connects adjacent expansion respectively；First flexible side 1 includes
First fixed section 11 and the first telescopic segment 12, the second flexible side 2 include the second fixed section 21 and the second telescopic segment 22, and third is flexible
3 sides include third fixed section 31 and third telescopic segment 32, and each fixed section all has the U-shaped sliding slot extended along its length
6, U-shaped sliding slot 6 is opened on the medial surface of fixed section, and each telescopic segment is respectively in corresponding U-shaped sliding slot 6 and slides with U-shaped sliding slot 6
Dynamic cooperation, the medial surface 7 of each telescopic segment are in same plane with the medial surface 8 of corresponding fixed section, are equipped with edge in each telescopic segment
The guide channel 9 that its length direction extends, sets that there are two screw holes 61 on the side wall of the U-shaped sliding slot 6 of fixed section, is mounted on the two spiral shells
The end of lock-screw 62 in hole 61 is embedded in guide channel 9；Protractor 4 is detachably arranged in any one top of set square
Point on；Each fixed section and telescopic segment are carved with length scale.
First it is flexible when 1, second is flexible 2 and third stretch side 3 fixed section all have the U extended along its length
Shape sliding slot 6, each telescopic segment are in corresponding U-shaped sliding slot 6 and are slidably matched with U-shaped sliding slot 6, so that three sides of set square
Length and the angle of three interior angles can be adjusted freely as needed, complete three edge lengths and three angle angles of set square
After adjusting, each lock-screw 62 is screwed, the cooperation of guide channel 9 and two lock-screws 62 is passed through, it can be ensured that is adjusting flexible side
During length, telescopic segment will not misplace, can fixed triangle ruler shape, due to each telescopic segment medial surface 7 with it is corresponding solid
The medial surface 8 for determining section is in same plane, and when drawing triangle using set square, three sides and three interior angles can be smoothly
It draws out, forms complete triangle.When needing to adjust the length on flexible side, lock-screw 62 is first slightly unclamped, makes to lock
62 end of screw is detached from 9 slot bottom of guide channel but still is in the cavity of guide channel 9, and telescopic segment is then moved to required position,
Lock-screw 62 is screwed again, so that 62 end of lock-screw is withstood 9 slot bottom of guide channel, the position of telescopic segment is fixed.Apex is set
It sets dismountable protractor 4 and removes protractor after fixing set square shape convenient for adjusting triangle ruler interior angle size as needed
It would not influence to be drawn using set square.
