Description

One kind is flexible can to survey teaching triangle

Technical field

The utility model relates to educational aid field, especially a kind of stretch can survey teaching triangle.

Background technique

Triangle is divided by side, is many by the type at angle point, in order to further student be given to demonstrate different types of triangle And its corresponding heterogeneity, it allows students to there is one to become apparent from clear understanding, is preparing triangle teaching aid at present When need to prepare many types；It is clearer in order to allow student to see due to teaching aid, volume relative to usually we oneself make Triangle teaching aid is much bigger, this there is a problem of in teaching process it is inconvenient to carry, no matter and be placed on where, It is all big to store occupied space, causes storage inconvenient, especially occupies the storage space of school, it is not very practical.

Utility model content

The goal of the invention of the utility model is: in view of the above problems, teaching triangle can be surveyed by providing a kind of stretch Shape allows the side of triangle to stretch and shrink by using the principle of flexible stick, demonstrates out different types of triangle, solution Determined the storage of existing triangle teaching aid and problem inconvenient for use, realized the diversification that triangle teaching aid uses, use at This is low, practical.

The technical solution adopted in the utility model is as follows:

The flexible of the utility model can survey teaching triangle, it includes slide bar and sliding sleeve, and the sliding sleeve is equipped with two, two Sliding sleeve is equipped in parallel at a fixed spacing, which is to slide gap；The both ends of the sliding sleeve are arranged with slide bar, form triangle A side；The slide bar can be in sliding sleeve telescopic slide；Relative to the one end for the slide bar being set in sliding sleeve, the slide bar it is another One end is the switching part of arc；The switching part is rotatablely connected by shaft and adjacent slide bar, passes through shaft head between slide bar Tail connects three arms of angle circularized；The shaft, which is located at, to slide in gap, and can slide in the range of sliding gap.

Due to using the above structure, using the principle of flexible stick, the side of triangle being allow to stretch and shrink, passing through control The length of triangle edges demonstrates out different types of triangle: equilateral triangle, isosceles triangle, scalene triangle；Acute angle Triangle, obtuse triangle, right angled triangle.Demonstration can be stretched when use into different types of triangle, do not used Can directly be accommodated horizon bar entirety in time, storage, the flexible teaching triangular structure that can survey is simple, stores and makes With conveniently, practicability is gone back with good.

The flexible of the utility model can survey teaching triangle, and the slide bar forms U-shaped structure with interconnecting piece thereon Slide bar has two extensions on slide bar, is arranged in sliding sleeve；The sliding sleeve two sides be equipped be slidably socketed with sliding sleeve it is U-shaped Slide bar；The U-shaped slide bar and sliding sleeve form it is closed slide gap, shaft shell rotation and is moved in the range of sliding gap It is dynamic.

Due to using the above structure, the slide bar and sliding sleeve of U-shaped mechanism form it is closed slide gap so that shaft can be This slide installed in gap it is stable slide to meet the transformation between different triangle types and size, while realizing storage The entirety at a horizontal ruler shape, convenient for storage can also as ruler use, structure is simple, low manufacture cost, for religion It learns using with beneficial contribution.

The flexible of the utility model can survey teaching triangle, protrude into the slide bar end in sliding sleeve and be equipped with fixture block one, The fixture block one is bonded setting with the inner sidewall of sliding sleeve；Fixture block two corresponding with fixture block one is equipped at the port of the sliding sleeve both ends, The inner sidewall of the fixture block two is bonded setting with the lateral wall of slide bar.

Further, the fixture block one is the first magnet；Two the second magnet of the fixture block；The inner sidewall of the sliding sleeve is Irony material is made.

Since using the above structure, the mechanism of magnet block is arranged so that slide bar has well relative to the sliding position of sliding sleeve Stability, avoid sliding into after certain position molding accidentally will positional shift the phenomenon that generation, and the magnet on sliding sleeve Magnet block on block and slide bar can attract each other and can be clamped, while avoiding slide bar from skidding off outside sliding sleeve, moreover it is possible in sliding sleeve and cunning With certain fastening effect when bar collapses, slide bar when upside down is avoided to skid off the damage for causing teaching aid outside sliding sleeve； Again, using magnet block structure design so that on some magnetic system blackboards in use, the triangle teaching aid of the utility model also Magnetic force is generated between energy and blackboard, so that displaying is lighter, is watched convenient for students, it is very convenient.

The flexible of the utility model can survey teaching triangle, and the quarter for indicating length unit is carved on the slide bar and sliding sleeve Degree.

It, can after stretching it due to using the above structure, designing different length unit scales on slide bar and sliding sleeve To indicate that icon reads the length on combination side according to triangle.Convenient for demonstrating the relationship of Atria side length and finding out triangle Perimeter.It is the flexible teaching triangle that can survey in hand, there is no need to prepare other triangles again, learning aid can all make With.It is Faculty and Students' teaching triangle knowledge indispensability good merchantable brand.

The flexible of the utility model can survey teaching triangle, be additionally provided with support rod between two sliding sleeves being equipped in parallel, described Any sliding sleeve is rotatablely connected in one end of support rod and two sliding sleeves, which is equipped with the bar slot for accommodating support rod, support rod The other end is can turn in the card slot being arranged on another sliding sleeve, and the clamping in card slot.

Further, the support rod is rotatablely connected by a compressed spring and sliding sleeve, so that after support rod enters bar slot, Vertical reset can be realized under the action of compressed spring.

Further, equipped with iron block, perhaps magnet block interacts with the iron block or magnet block in the card slot Boom end is supported to be equipped with magnet block or iron block.

Since using the above structure, support rod can also keep the relative position between sliding sleeve, uses, look for convenient for user Level is set, and can also guarantee shaft normally slides gap, and structural stability is more preferably.

In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:

1, the flexible teaching triangular structure that can survey of the utility model is simple, and it is convenient to use and store；

2, manufacture craft is simple, and use cost is low；

3, the triangle of various different sizes and type can be both transformed into, moreover it is possible to use as ruler, functional；

4, structural stability is good.
