Abstract
The utility model provides a multifunctional square ruler, which is characterized in that the square ruler is composed of four side-to-side single rulers. The adjacent sides of the single rulers are respectively hinged through hinges or alternately through moveable joints. The moveable joints can slip along the single ruler body lengthwise. The utility model has the features of simple structure, convenient use and multi-function in one ruler, which not only helps the students of lower ages draw various quadrilateral figured, but also can be used as a ruler and an L-shaped ruler as well.
Description
Technical field
The utility model relates to teaching appliance, particularly relates to the square chi of a kind of novel multifunctional.
Background technology
Traditional teaching appliance generally all provides complicated function and finishes comparatively complicated operations to help the student, but for a lot of pupils, these complicated operations exercises are then very remote, the realistic problem that it faced is how to finish some simple mapping or operations, when particularly the low age pupil does simple graph, as square, during basic geometric figure such as rectangle or parallelogram, because pupil's trick mating capability is poor, often be difficult to only depend on ruler to make the figure of standard, this not only can increase children's learning difficulty, and tend to cause them through difficult repeatable operation, in constantly failing, lose patience gradually and confidence, thereby make children produce fear of difficulty and personality early, the enjoyment that no complex can be learnt and cultivate correct interest, such present situation is far from each other with the country long-term policy for education of carrying out to children's Reduction of Students' Study Load.
The utility model content
Defective and deficiency at existing teaching aid existence, the utility model provides a kind of can help children's multi-functional square chi of basic geometrical pattern such as square, rectangle, parallelogram of standard that easily draws, and the utility model can also be in order to measure length and angle.
The technical solution of the utility model is as follows:
Multi-functional square chi is characterized in that: described square chi is made up of four end to end single chis, and described each single chi abutting end adopts the hinged or removable connector of hinge alternately to link to each other respectively, and described removable connector can be along single chi chi body straight skidding.
Have at least a chi body to be provided with the scale that to measure length in described each single chi.
Described square chi has at least a bight to be provided with the angle square that can take measurement of an angle.
The bight at a pair of diagonal angle each other of described square chi is provided with described angle square.
Described angle square is arranged at described hinged place and overlaps with the pivot of this hinge.
Also be provided with the locking device of lockable angle on the described hinge.
Described removable connector comprises that two stacks are provided with and the hinged slide block in the center, described slide block has at least a side to have concaveconvex structure, described chi body is provided with and the suitable bar-shaped trough of described slider profile, the side of described bar-shaped trough and described slide block side concaveconvex structure are suitable, and described each slide block is embedded in this groove respectively and can moves and can rotate along its hinged center with the chi body along this groove.
Described slide block is a disk rotor, and its outer circumference surface has, and protrude at the middle part or the dovetail structure of depression.
Technique effect of the present utility model is:
The utility model is to be made up of four end to end single chis, and described each single chi abutting end adopts the hinged or removable connector of hinge alternately to link to each other respectively, and described removable connector can be along single chi chi body straight skidding.
The angle square of this spline structure can utilize hinge or the removable connector between each single chi to make between single chi mobile mutually, and can change angle between each adjacent single chi arbitrarily, thereby can conveniently draw square, rectangle, parallelogram and pattern such as trapezoidal, thoroughly changed the present situation of underage child picture difficulty in the conventional teaching, remedied the deficiency in the elementary education, make the low age pupil no longer difficult in drawing various fundamental figures, self-confidence that can fast happy its study of enhancing of insight learning in drawing easily also can alleviate their learning pressure simultaneously.
In addition, in order to increase function of the present utility model, make a chi use more, the angle square that the utility model also is provided with the ruler scale and can takes measurement of an angle on single chi of square chi, conveniently to carry out the measurement of length and angle, from another aspect, also can avoid increasing its burden owing to children need prepare more chi tool.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of removable connector.
The single chi of 1-, the 2-chute, the 3-fixed hinge, 4-moves connector, 401-slide block, 402-slide block, 5-connector hinge, 6-ruler scale, 7-angle square.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Be illustrated in figure 1 as the structural representation of the multi-functional square chi of the utility model.Also can the associate with polygonal frame structure of root or more single chi 1 composition of the quadrilateral frame works of the square chi of the utility model for joining end to end and forms by four single chis 1, but as expansion of the present utility model, this square chi.
Two pairs of diagonal positions of square chi are connected each single chi 1 with mobile connector 4 by fixed hinge 3 respectively, mobile connector 4 is that the slide block 401 and 402 that two stacks are provided with is formed, be provided with the trapezium structure of evagination on each slide block outer circumference, as shown in Figure 2, slide block 401 is connected by the connector hinge 5 that is arranged at its center with 402, each slide block can rotate around this connector hinge 5 respectively, single chi 1 is provided with the chute 2 suitable with slider profile, chute 2 both sides are provided with and the corresponding dovetail groove of slide block excircle trapezium structure, slide block 401,402 are embedded at respectively in the chute 2, slide block and chute are chimeric mutually by trapezium structure, can guarantee that slide block neither can break away from again and can move along chute 2 from chute 2, thus the distance of regulating 1 of each single chi.Also can be dovetail groove and, can certainly replace trapezium structure with the slide block arranged outside, as dovetail structure or arc structure etc. by other concaveconvex structure with the trapezium structure that the chute inboard is arranged to protrude.
Utilization is arranged at the fixed hinge 3 and the mobile connector 4 in each bight of square chi, can realize adjusting the angle and the length on each limit easily, with square, rectangle and the trapezoidal and parallelogram of drawing various sizes.
Fixed hinge 3 places are provided with angle square 7, and this angle square 7 both can be used for measuring the angle in this square chi bight, also can use separately to take measurement of an angle.
Also be provided with ruler scale 6 on single chi 1, this ruler scale 6 both can be used for the tolerance tetragonal size of painting, also can be separately as ruler with measurement length.
The above only is a preferred implementation of the present utility model.Should be pointed out that for a person skilled in the art, can also make a lot of distortion and improvement, but these distortion and improvement all will fall into protection domain of the present utility model according to invention essence of the present utility model.
