Description

A kind of lattice chi of trace

The utility model relates to a kind of lattice chi of trace.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, and articles for use are write or painted to the big class of office appliance, the assistant product group of writing or draw, ruler technical group field.Be numbered B43L 7/00.

At present, the technology about ruler existing and that once had was all done very fruitful effort to the functional requirement of ruler, also once did many outstanding designs.As declaring of the nineteen ninety-five Decree of Patent Office of China by Wu Juntian, Granted publication number is CN2204727Y, China Patent No. (ZL) is: No. 94220213.9 utility model title is the utility model patent of roller multifunctional drawing ruler, the technical scheme that is adopted, at the ruler technical elements is a routine of great value invention, and it has solved the problem of the multifunction requirement of drawing rule effectively.But still have some deficits, it also is difficult to solve the problem easy and simple to handle of drawing course.

The purpose of this utility model is to provide a kind of lattice chi of trace.To solve the problem easy and simple to handle of drawing course.

The purpose of this utility model is achieved in that the lattice chi of a kind of trace of this utility model.Mainly constitute by ruler, unit drawing lattice, elastic wire, seal line.Its major part elastic wire is by selecting for use on the market.The unit map grid is cut molded making with hard moulding material.In the centre of ruler is groove in the middle of, after unit drawing lattice string with elastic wire, is connected in the groove of ruler, is seal lines in the bottom of unit drawing lattice.So just realized the purpose of this utility model.

The technology of the utility model and original ruler has been compared an advantage and improvement;

The first, because the utility model has designed unit drawing lattice in technical scheme, line is accurate, more convenient operation.Thereby just can more effectively solve the problem easy and simple to handle of drawing course.

Accompanying drawing provides structural representation of the present utility model:

Fig. 1: be mansion of the present utility model TV structure schematic diagram:

Fig. 2: be that unit of the present utility model drawing lattice side is cutd open structural representation:

Fig. 3: be side-looking structural representation of the present utility model:

The numbering of parts explanation in the schematic diagram: (1) ruler (2) unit drawing lattice (3) elastic wires (4) seal line

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in the figure, the lattice chi of a kind of trace of the utility model. Mainly by ruler (1), unit Drawing lattice (2), elastic wire (3), seal line (4) consist of. Its major part elastic wire (3) by selecting on the market. Unit map grid (2) is cut molded making with the hard plastic material. In ruler (1) The centre be groove in the middle of, after unit drawing lattice (2) string with elastic wire (3), connection In the groove of ruler (1), be seal line (4) in the bottom of unit drawing lattice (2). So just Realized the purpose of this utility model. Thereby just can solve the problem easy and simple to handle of drawing course.

Below by embodiment, the utility model is done more detailed description:

Embodiment 1, in use, line if desired, only need align size, find out scale, press with the unit drawing lattice (2) under the scale, elastic wire (3) affects the unit before all to give chart board (2) downward, utilize the size straight line that seal line (2) marks to be needed, after loosing one's grip, unit drawing lattice (2) return.Thereby just can realize the purpose of this utility model.

Realize that preferred plan of the present utility model is is material with the rigid plastics, utilize the basic equipment of compression moulding factory, take to assemble in batch to produce by batch, the demand with in supply study or the drawing course so just can realize practical value of the present utility model and economic worth better.

Claims (1)

1. the lattice chi of a trace, it is to be made of ruler (1), unit drawing lattice (2), elastic wire (3), seal line (4), in the centre of ruler (1) is groove in the middle of, after unit drawing lattice (2) string with elastic wire (3), be connected in the groove of ruler (1), in the bottom of unit drawing lattice (2) is seal line (4), it is characterized in that all unit drawing lattice (2) suitable string of elastic wire (3).
