Abstract

The utility model relates to a uniform measuring device for students, which is formed by short-head long connecting bars, long-head long connecting bars, rotating connecting shafts, short-head short connecting bars, a hand-held circular disc and long-head short connecting bars. The long-head long connecting bars and the short-head long connecting bars jointly form a main body piece. Symmetrical through holes are arranged at the two ends of the long-head long connecting bars and the short-head long connecting bars and at positions in the middle. The rotating connecting shafts are arranged in the through holes in a penetrating way to form a parallelogram structure between the two adjacent long-head long connecting bars or short-head long connecting bars. The long-head long connecting bars and the short-head long connecting bars are connected together by the rotating connecting shafts to form a series of parallelograms. The hand-held circular disc arranged in the center at the utmost front end or the utmost rear end of the series of parallelograms. The short-head short connecting bars are arranged and are connected with the long-head long connecting bars. The long-head short connecting bars are arranged and are connected with the short-head long connecting bars. The utility model has the advantages that the overall structure is simple, the operation and the use are convenient, and the uniform measuring device is suitable not only for students but also for ordinary measurement operations.

Description

The student uses halving measure device

Technical field:

The utility model relates to the student and learns to use servicing unit, relates in particular to the student and uses halving measure device.

Background technology:

Branch utensils such as the tolerance of prior art are a kind of devices of plank frame, use this device five equilibrium line segment, must on the five equilibrium plate, seek the unit length that quilt waits the branch line segment, because the bisector gradient on the five equilibrium plate is bigger, influence the accuracy of Along ent, often error is bigger when doing the five equilibrium operation, even is not fit to use.

The utility model content:

The purpose of this utility model is, overcomes the deficiencies in the prior art part, provides a kind of student to use halving measure device, with the metering of directly perceived and accurate tolerance, both can be used as the desirable utensil of student when doing one's assignment, and also can be used as the aid of routine office work.

Student described in the utility model uses halving measure device, includes brachycephaly long connecting rod, long head length connecting rod, the axle that is rotationally connected, brachycephaly short connecting rod, hand-held disk and a long short connecting rod and forms.Said long head length connecting rod and brachycephaly long connecting rod are jointly as main component of the present utility model, in the two ends of said long head length connecting rod and brachycephaly long connecting rod and position placed in the middle, be provided with the through hole of symmetry, form to penetrate in the through hole, be provided with the axle that is rotationally connected, make between adjacent two long head length connecting rods or the brachycephaly long connecting rod, form the structure of a parallelogram.By long head length connecting rod and brachycephaly long connecting rod, a succession of parallelogram that is connected to form through the axle that is rotationally connected foremost or least significant end, install terminal point with the hand-held disk of form placed in the middle as this, also be manual handpiece.Be connected with long head length connecting rod, be provided with the brachycephaly short connecting rod, be connected with the brachycephaly long connecting rod, then be provided with a long short connecting rod, and the outermost end of a brachycephaly short connecting rod and a long short connecting rod, all be to connect by the axle that is rotationally connected to be arranged on the hand-held disk, can control the folding of this device easily by the hand-held disk.

Student described in the utility model uses halving measure device, overall structure is simple, easy for operation, as long as guarantee the coefficient of friction unanimity of all axles that is rotationally connected, the form of the utility model folding will be consistent, just formed a series of parallelogram will be consistent, and the study that is fit to the student is used, and also is fit to general metric operations.

Description of drawings:

Accompanying drawing is the structural representation of student described in the utility model with halving measure device.The long head length connecting rod of the 1-brachycephaly long connecting rod 2-3-long short connecting rod of a 4-brachycephaly short connecting rod 5-hand-held disk 6-that is rotationally connected

The specific embodiment:

Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: student described in the utility model uses halving measure device, includes brachycephaly long connecting rod 1, long head length connecting rod 2, the axle 3 that is rotationally connected, brachycephaly short connecting rod 4, hand-held disk 5 and a long short connecting rod 6 and forms.Said long head length connecting rod 2 and brachycephaly long connecting rod 1 are jointly as main component of the present utility model, in the two ends of said long head length connecting rod 2 and brachycephaly long connecting rod 1 and position placed in the middle, be provided with the through hole of symmetry, form to penetrate in the through hole, be provided with the axle 3 that is rotationally connected, make between adjacent two long head length connecting rods 2 or the brachycephaly long connecting rod 1, form the structure of a parallelogram.By long head length connecting rod 2 and brachycephaly long connecting rod 1, through the axle 3 a succession of parallelogram that are connected to form that are rotationally connected foremost or least significant end, with the hand-held disk 5 of form placed in the middle terminal point, also be manual handpiece as this device.Be connected with long head length connecting rod 2, be provided with brachycephaly short connecting rod 4, be connected with brachycephaly long connecting rod 1, then be provided with a long short connecting rod 6, and the outermost end of a brachycephaly short connecting rod 4 and a long short connecting rod 6, all be to connect by the axle 3 that is rotationally connected to be arranged on the hand-held disk 5, can control the folding of this device easily by hand-held disk 5.Student described in the utility model uses halving measure device, overall structure is simple, easy for operation, as long as guarantee the coefficient of friction unanimity of all axles 3 that is rotationally connected, the form of the utility model folding will be consistent, just formed a series of parallelogram will be consistent, and the study that is fit to the student is used, and also is fit to general metric operations.
