Abstract
The utility model discloses a folding son and mother ruler which comprises a son ruler 1 (1), a mother ruler (2) and a son ruler 2 (3). The length of the son ruler 1 (1) is equal to the length of the son ruler 2 (3). And the length of the son ruler 1(1) and the son ruler 2 (3) is one second of the length of the mother ruler (2). The length of the mother ruler (2) can be decided according to the need. Two bar-type embossments are arranged in centerlines of surfaces of the son ruler 1 (1) and the son ruler 2 (3). A bar-type groove is arranged in a centerline of the surface of the mother ruler (2). The embossments are rightly clamped inside the groove, and therefore the ruler can be folded to store, and is small, exquisite and portable. Two spherical embossments are arranged at one ends of the bar-type embossments of the son ruler 1 (1) and the son ruler 2 (3). The spherical embossments can be clamped at end portions of the bar-type groove of the mother ruler (2). The son ruler 1 (1), the mother ruler (2) and the son ruler 2 (3) are connected by the spherical embossments, and therefore the length of the ruler is enabled to be longer than an ordinary stationery ruler. The son ruler 1 (1), the mother ruler (2) and the son ruler 2 (3) can be used independently, and therefore drawing demands of different lengths can be met.
Description
Technical field
The utility model relates to a kind of ruler, says more specifically a kind of composite ruler that can fold.
Background technology
As everyone knows, ruler is the necessary tool of people's study and work, but because the long ruler of length is inconvenient to carry, and the length of common stationery rule in the market is confined to 20 centimetres, when we need longer length, will be helpless.
Summary of the invention
The purpose of this utility model provides a kind of composite ruler that can fold.
The purpose of this utility model can realize in the following manner: a kind of folding composite ruler is comprised of sub-chi 1 (1), female chi (2) and sub-chi 2 (3) three parts.The equal in length that it is characterized in that sub-chi 1 (1) and sub-chi 2 (3), 1/2nd of female chi (2) length, the length of female chi (2) can be decided as required, sub-chi 1 (1), sub-chi 2 (3) surperficial midline all have a strip bulge, the surperficial midline of female chi (2) has a strip groove, and projection can be stuck in the groove just; There is a hemisphere jut end of the strip bulge of sub-chi 1 (1), sub-chi 2 (3), and hemisphere jut can be stuck in the end of female chi (2) strip groove, has connected sub-chi 1 (1), female chi (2) and sub-chi 2 (3).Sub-chi 1 (1), female chi (2) and sub-chi 2 (3) can adopt plastics or stainless steel material.
The utility model compared with prior art has the following advantages: when folding, sub-chi 1 (1) can be embedded on female chi (2) with sub-chi 2 (3), and is small and exquisite portable; During stretching, extension, the total length of ruler is longer than common stationery rule, and sub-chi 1 (1), sub-chi 2 (3) also can use separately with female chi (2), satisfy the drawing demand of all lengths.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
As follows with reference to accompanying drawing 1: a kind of folding composite ruler is comprised of sub-chi 1 (1), female chi (2), sub-chi 2 (3) three parts.The equal in length that it is characterized in that sub-chi 1 (1) and sub-chi 2 (3), 1/2nd of female chi (2) length, the length of female chi (2) can be decided as required, sub-chi 1 (1), sub-chi 2 (3) surperficial midline all have a strip bulge, the surperficial midline of female chi (2) has a strip groove, and projection can be stuck in the groove just; There is a hemisphere jut end of the strip bulge of sub-chi 1 (1), sub-chi 2 (3), and hemisphere jut can be stuck in the end of female chi (2) strip groove, has connected sub-chi 1 (1), female chi (2) and sub-chi 2 (3).When packing up when depositing ruler, sub-chi 1 (1) all is stuck on female chi (2) with sub-chi 2 (3), ruler is small and exquisite portable like this; When needs use ruler, sub-chi 1 (1) and sub-chi 2 (3) are stuck in respectively the end of female chi (2) by hemisphere jut, make ruler longer than the length of common stationery rule, sub-chi 1 (1), sub-chi 2 (3) also can use separately with female chi (2), satisfy the drawing demand of all lengths.
Claims (2)
1. folding composite ruler, formed by sub-chi 1 (1), female chi (2) and sub-chi 2 (3) three parts, the equal in length that it is characterized in that sub-chi 1 (1) and sub-chi 2 (3), 1/2nd of female chi (2) length, the length of female chi (2) can be decided as required, sub-chi 1 (1), sub-chi 2 (3) surperficial midline all have a strip bulge, the surperficial midline of female chi (2) has a strip groove, and projection can be stuck in the groove just; There is a hemisphere jut end of the strip bulge of sub-chi 1 (1), sub-chi 2 (3), and hemisphere jut can be stuck in the end of female chi (2) strip groove, has connected sub-chi 1 (1), female chi (2) and sub-chi 2 (3).
2. a kind of folding composite ruler according to claim 1, it is characterized in that: sub-chi 1 (1), female chi (2) and sub-chi 2 (3) can adopt plastics or stainless steel material.
