Abstract
The utility model discloses a kind of odd test ruler, comprise the graduated chi body of mark, it is characterized in that: described chi body comprise multiple can the unit chi body of relative sliding, one in adjacent two described unit chi bodies is provided with chute along its length, and described in another, the end of unit chi body is provided with the slide block matched with described chute.The utility model structure is simple, carry, use more convenient.
Description
Technical field
The utility model relates to a kind of ruler, particularly relates to a kind of odd test ruler, belongs to stationery.
Background technology
At present, along with the continuous progress of manufacturing technology, the living standard of people also improves constantly thereupon, and commodity and the stationery of various attractive in appearance, fashion, diverse in function constantly enrich the daily life that people enrich.But, find in Long-Time Service, wherein part stationery product still has multiple weak point, such as: students ruler used in everyday according to measurement category usually have 5 centimetres, 10 centimetres, 20 centimetres or 30 centimetres etc., students sometimes needs to carry and many ruler could be met user demand, therefore, cumbersome.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of structure odd test ruler simple, easy to use.
For solving the problems of the technologies described above, the utility model provides a kind of odd test ruler, comprise the graduated chi body of mark, described chi body comprise multiple can the unit chi body of relative sliding, one in adjacent two described unit chi bodies is provided with chute along its length, and described in another, the end of unit chi body is provided with the slide block matched with described chute.
An end of described unit chi body is formed with lower concave part, and the end shape of adjacent two described unit chi bodies coordinates.
Described slide block is connected by the end of the first flexible member with described unit chi body.
Described lower concave part has the cell body of accommodating described slide block.
Be provided with two intermediate plates to scale in described cell body, described two intermediate plates are fixedly connected with respectively by the inwall of the second flexible member with described cell body.
Described first flexible member and described second flexible member are helical spring.
Compared with prior art, the beneficial effects of the utility model are: due to odd test ruler of the present utility model, comprise multiple slidably unit chi body, pull can be selected to open several unit chi body according to different measurement demands, when carrying, just can be overlapped into a shorter portable ruler, therefore, odd test ruler structure of the present utility model is simple, easy to use and be easy to carry.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is deployed configuration schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details: shown in Figure 1, a kind of odd test ruler, comprise the graduated chi body 2 of mark, described chi body 2 comprise multiple can the unit chi body 4 of relative sliding, wherein, one in adjacent two described unit chi bodies 4 is provided with chute 6 along its length, the end of unit chi body 4 described in another is provided with the slide block 8 matched with described chute 6, when the length of measured object is greater than the length of unit chi body 4, only need twitch the unit chi body be attached thereto, even if originally overlapping chi body launches, thus meet the measurement demand of different lengths.
Shown in Figure 1, be formed with lower concave part 9 in an end of unit chi body 4, the end shape of adjacent two described unit chi bodies 4 coordinates, and can ensure the flatness (shown in Figure 2) after ruler expansion like this.
For improving the flatness after ruler expansion and stability in use further, the first flexible member 10 that slide block 8 is consisted of helical spring is connected with the end of described unit chi body 4.Described lower concave part 9 is provided with the cell body 12 of accommodating described slide block 8.Be provided with two intermediate plates 14 to scale in cell body 12, the second flexible member 16 that described two intermediate plates 14 are formed respectively by helical spring is fixedly connected with the inwall of described cell body 12, such structural design can fully ensure ruler launch after stability.
The foregoing is only better embodiment of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; in every case those of ordinary skill in the art modify or change according to the equivalence that the utility model institute disclosure is done, and all should include in the protection domain recorded in claims.
