Abstract
The utility model relates to a hinge joint straightedge which comprises a first straightedge, a second straightedge, a screw barrel with inner threads and a bolt. A first open groove is formed in the position, close to the tail end, of upper end face the first straightedge, and a first step plate is correspondingly formed on the bottom portion of the open groove. A second open groove is formed in one side, close to the tail end of the first straightedge, of the lower end face of the second straightedge, and a second step plate is correspondingly formed on the bottom portion of the second open groove. The second step plate is in lap joint with the first step plate, an inverted counter bore capable of containing the screw barrel is formed in the first step plate in a transverse direction, a first through hole is formed in the bottom face of the inverted counter bore, a second through hole is formed in the position, corresponding to the first through hole, of the second step plate, and the screw barrel penetrates through the first through hole and the second through hole in sequence and is fixedly arranged through the bolt. Due to the fact that the first straightedge and the second straightedge are arranged through hinge joint of the screw barrel and the bolt, the measuring range of the hinge joint type straightedge is made to be larger, and applicability is wider.
Description
Technical field
The utility model relates to a kind of measurer, is specifically related to a kind of ruler.
Background technology
Ruler, as its name suggests, straight ruler, it is a kind of gauge with accurate straight line seamed edge, be used for measuring length, and be widely used in mathematics, measure, subjects such as engineering, and in actual use, usually exist the curtailment of a ruler to draw to measure, often need the drafting of going that continues repeatedly, therefore also make staff's operation relative complex, and the straight line of being drawn makes to require straight straight line to produce small gradient originally because midway interrupted is easy to generate deviation, especially in the engineering design drawing of always following rigorous attitude, the influence that this kind deviation produces is very big.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of radial type ruler simple in structure, applied widely is provided.
For achieving the above object, the utility model adopts a kind of radial type ruler, comprise first ruler, second ruler, swivel nut and bolt with internal thread, on the upper surface of described first ruler, be provided with first fluting near the position of tail end, and form the first step plate in the fluting bottom accordingly, pass through the first arc surface transition between the upper surface of this first step plate and first ruler; On the lower surface of described second ruler, offer second fluting near a side of the first ruler tail end, and the second step plate is formed accordingly on the bottom of this second fluting, passes through the second arc surface transition between the lower surface of this second step plate and described second ruler; Described second step plate and first step plate form overlap joint, offer in a lateral direction enough inversion counterbores of ccontaining swivel nut on the described first step plate, described inversion counterbore bottom surface offers first through hole, offer second through hole with the corresponding position of described first through hole on the described second step plate, described swivel nut passes described first through hole and second through hole successively and installs and then form hinged between first ruler and second ruler by bolting.
The utility model is by the improvement to prior art, because first step plate that is provided with on first ruler and second ruler and second step plate overlap and pass swivel nut it is threaded with bolt formation, the conspicuous realization is merged together use with two rulers, but enlarged the weight range of ruler greatly, made that the scope of application of ruler of the present utility model is wider.

The specific embodiment
Shown in Fig. 1-4, specific embodiment of the utility model is a kind of radial type ruler, comprise first ruler 1, second ruler 2, swivel nut 3 and bolt 4 with internal thread, on the upper surface of described first ruler 1, be provided with first fluting 10 near the position of tail end, and form first step plate 11 in fluting 10 bottoms accordingly, pass through 12 transition of first arc surface between the upper surface of this first step plate 11 and first ruler 1; On the lower surface of described second ruler 2, offer second fluting 20 near a side of first ruler, 1 tail end, and second step plate 21 is formed accordingly on the bottom of this second fluting 20, passes through 22 transition of second arc surface between the lower surface of this second step plate 21 and described second ruler 2; Described second step plate 21 forms overlap joint with first step plate 11, offer the inversion counterbore 110 of enough ccontaining swivel nut 3 in a lateral direction on the described first step plate 11, described inversion counterbore 110 bottom surfaces offer first through hole 111, offer second through hole 210 with described first through hole 111 corresponding positions on the described second step plate 21, described swivel nut 3 passes described first through hole 111 and second through hole 210 and successively by bolt 4 fixed installations and then form hinged between first ruler 1 and second ruler 2.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.Industry technical staff should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Protection domain of the present utility model defines according to appended claim and equivalent thereof.
