Abstract
The utility model relates to a kind of ruler of flexible connection, comprise the first ruler body, the second ruler body, be flexibly connected by bearing pin between the first described ruler body and the second ruler body, several the first installing holes are offered on the length direction of the first ruler body, several the second installing holes are offered, at the first installing hole with the second installing hole is movable is connected with cross bar on the length direction of the second ruler body.The utility model in use, angle between two rulers can regulate, after the adjustment is completed, a triangle is surrounded, because triangle has stability by being provided with between cross bar and two rulers, two rulers can be fixed, being convenient to the figure drawing different angles, when not using, taking cross bar away, two rulers are combined, is convenient to deposit.
Description
Technical field
The utility model relates to realia technical field, particularly relates to a kind of ruler of flexible connection.
Background technology
Ruler is widely used in the subjects such as mathematics, measurement, engineering, also have person be between chi, be a kind of very conventional measuring length instrument, this stationery is very general, and almost every pupil all staff one, are generally used for measuring shorter distance or drawing straight line.
When current teacher draws on blackboard, need to use ruler, but existing ruler can not adjusting angle, is using inconvenience.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of ruler of flexible connection.
The utility model is achieved through the following technical solutions:
A kind of ruler of flexible connection, comprise the first ruler body, the second ruler body, be flexibly connected by bearing pin between the first described ruler body and the second ruler body, several the first installing holes are offered on the length direction of the first ruler body, several the second installing holes are offered, at the first installing hole with the second installing hole is movable is connected with cross bar on the length direction of the second ruler body.
As optimal technical scheme of the present utility model, the two ends of described cross bar are arranged on the first installing hole and the second installing hole respectively by pin.
As optimal technical scheme of the present utility model, described first ruler body is identical with the length of the second ruler body, and thickness is identical, and adopts same material to make.
As optimal technical scheme of the present utility model, a long limit of described first ruler body and the second ruler body is provided with graduation mark.
Compared with prior art, the beneficial effects of the utility model are: in use, the angle between two rulers can regulate the utility model, after the adjustment is completed, a triangle is surrounded by being provided with between cross bar and two rulers, because triangle has stability, two rulers can be fixed, be convenient to the figure drawing different angles, when not using, take cross bar away, two rulers are combined, is convenient to deposit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-first ruler body; 2-second ruler body; 3-bearing pin; 4-first installing hole; 5-second installing hole; 6-cross bar.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
The ruler of described a kind of flexible connection, comprise the first ruler body 1, second ruler body 2, be flexibly connected by bearing pin 3 between the first described ruler body 1 and the second ruler body 2, several the first installing holes 4 are offered on the length direction of the first ruler body 1, several the second installing holes 5 are offered on the length direction of the second ruler body 2, at the first installing hole 4 with the second installing hole 5 is movable is connected with cross bar 6, the two ends of described cross bar 6 are arranged on the first installing hole 4 and the second installing hole 5 respectively by pin, when two rulers are adjusted to certain angle, by pin, cross bar 6 is fixed on ruler.
Described first ruler body 1 is identical with the length of the second ruler body 2, and thickness is identical, and adopts same material to make, and a long limit of the first ruler body 1 and the second ruler body 2 is provided with graduation mark.
In use, angle between two rulers can regulate, after the adjustment is completed, a triangle is surrounded, because triangle has stability by being provided with between cross bar 6 and two rulers, two rulers can be fixed, being convenient to the figure drawing different angles, when not using, taking cross bar away, two rulers are combined, is convenient to deposit.
