Abstract
The utility model relates to an integrated compass. The integrated compass is characterized by mainly comprising a compass and a dividing ruler; a sliding chute is arranged on the bottom part of the dividing ruler; corresponding scales are marked on the upper part; a threaded hole is respectively formed in the middle points of a needle fixing rod and a painting pen holder of the compass, and the threaded holes are respectively provided with a corresponding fixed threaded rod and a corresponding sliding threaded rod; the sliding threaded rod is matched with the sliding chute of the dividing ruler; and one end of the dividing ruler is connected with the needle fixing rod through the fixed threaded rod, and the painting pen holder can slide oppositely to the dividing ruler by coordinating with the sliding chute through the sliding threaded rod. The integrated compass disclosed by the utility model is simple in structure and convenient to carry, can fast estimate radius of the painted circle through the dividing ruler, and is particularly suitable for the use by a great number of primary and secondary school students.
Description
Technical field
The utility model relates to a kind of study article, especially a kind of integrated compasses.
Background technology
Compasses are to be used for the instrument of draw circles or string in mathematics and drawing, are usually used in construction with ruler and compasses.Compasses are drawing instruments of painting round usefulness, and two pin are arranged, and the upper end is hinged, and the lower end can arbitrarily separate or close up, with the size of the adjustment arc radius of being painted.The end of a pin is a needle point, and the end of another pin can be packed into and painted the pin of the pencil line or the line of ink marker.The compasses that have are loaded onto extension rod, and bigger circle can draw.Compasses are divided into trammel, springer bow and the heart bow compasses etc. of living.
Traditional compasses need cooperate rule to use because structure is too single during graphing, inconvenience very has been difficult to satisfy modern's demand.
The utility model content
In order to make existing compasses more meet modern's the demand for function, the utility model provides a kind of integrated compasses, and it improves on original basis, has realized the integrated of compasses and ruler through the rule that is connected on the supporting leg.
In order to realize that the technical scheme that the utility model purpose is adopted is: a kind of integrated compasses is characterized in that: it mainly is made up of compasses, rule; Described rule bottom is provided with chute, and top indicates corresponding scale; Described compasses decide shank and paintbrush bar midpoint is provided with screwed hole, and dispose corresponding retaining thread bar and threaded rod slidably; Described slidably threaded rod matches with the rule chute; Described rule one end connects through the retaining thread bar decide shank, the paintbrush bar can through threaded rod slidably and chute cooperate and rule slides relatively.
Described paintbrush bar is a hollow structure, and number can be placed with pen core in inside, and paintbrush masthead end is provided with the promotion slide block.
The beneficial effect of the utility model is: simple in structure, easy to carry, through rule, can estimate drawn radius of a circle fast, and be particularly suitable for numerous students in middle and primary schools and use.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
Fig. 1 is the utility model front view.
Wherein, 1-compasses, 2-promote slide block, 3-rule, slidably threaded rod, 5-chute, 6-paintbrush bar, 7-retaining thread bar, 8-decide shank to 4-.
The specific embodiment
In first embodiment shown in Figure 1, a kind of integrated compasses is characterized in that: it mainly is made up of compasses, rule; Described rule bottom is provided with chute, and top indicates corresponding scale; Described compasses decide shank and paintbrush bar midpoint is provided with screwed hole, and dispose corresponding retaining thread bar and threaded rod slidably, described slidably threaded rod matches with the rule chute; Described rule one end connects through the retaining thread bar decide shank, the paintbrush bar can through threaded rod slidably and chute cooperate and rule slides relatively.
Described paintbrush bar is a hollow structure, and number can be placed with pen core in inside, and paintbrush masthead end is provided with the promotion slide block.
In second embodiment shown in Figure 1,,, be the circular radius of drawing so when drawing circle, the pairing scale of threaded rod multiply by two on the paintbrush bar because the position of threaded rod is in the mid point of compasses supporting leg.
In the 3rd embodiment shown in Figure 1, after the pencil of paintbrush bar uses up, can promote slide block, drive the inner pencil-lead of paintbrush bar and move down, change.
Claims (2)
1. integrated compasses, it is characterized in that: it is made up of compasses, rule; Described rule bottom is provided with chute, and top indicates corresponding scale; Described compasses decide shank and paintbrush bar midpoint is provided with screwed hole, and dispose corresponding retaining thread bar and threaded rod slidably, described slidably threaded rod matches with the rule chute; Described rule one end connects through the retaining thread bar decide shank, the paintbrush bar can through threaded rod slidably and chute cooperate and rule slides relatively.
2. according to claims 1 described a kind of integrated compasses, it is characterized in that: described paintbrush bar is a hollow structure, and pen core can be placed in inside, and paintbrush masthead end is provided with the promotion slide block.
