Abstract

The utility model relates to a novel telescopic fixing ruler which is composed of a card, a ledger plate, a spring and a ruler. As the card and the ledger plate are designed in the technical proposal, the ruler can be fixed. The utility model is characterized in that a bolt of card is fixed on the nearby place of the ledger plate. The utility model is a novel telescopic fixing ruler which has practical value.

Description

The novel telescopic fixed ruler

(1) technical field:

The utility model relates to the novel telescopic fixed ruler.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write or drawing appliance; The big class of office appliance is write or drawing article; Book with or drawing assistant product group, the ruler technical group field.

(2) background technology:

At present, the technology about ruler existing and that once had was all done very fruitful effort to the demand of novel telescopic fixed ruler, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Zhang Zhen, Granted publication number is CN2224737Y, China Patent No. (ZL) is: No. 95230665.4 utility model title is the utility model patent of " the anti-multifunctional drawing ruler of smearing ", the technical scheme that is adopted.At the ruler technical elements is a routine of great value invention, and it has solved the anti-problem that is coated with of drawing rule effectively.But still have some deficits, it also is difficult to solve can not be the fixing problem of chi when drawing.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of novel telescopic fixed ruler.Can not be when drawing the fixing problem of chi to solve.

The purpose of this utility model is achieved in that the novel telescopic fixed ruler of this utility model.Mainly constitute by clamp, fixed head, spring, ruler.Its spring is by selecting for use on the market.Its clamp, fixed head, ruler are rectangular shapes, use plastic material, through the injection moulding processing and manufacturing.Clamp adopts the screw fixing means to be installed in the position, next door of fixed head, constitutes " " combination of shapes structure, and function has been a fixation.Spring adopts adhering method to be connected the position, next door of fixed head, constitutes integrative-structure, and function has been an elastic reaction.So just realized the purpose of this utility model.

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

The first, because the utility model designed clamp and fixed head in technical scheme, so fixing ruler; Can not be when drawing thereby just can more effectively solve the fixing problem of chi.

(4) description of drawings:

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is the Facad structure schematic diagram of novel telescopic fixed ruler of the present utility model;

The numbering of parts explanation in the schematic diagram: 1 clamp, 2 fixed heads, 3 springs, 4 rulers

(5) specific embodiment:

In the optimum implementation of novel telescopic fixed ruler of the present utility model, its technical scheme is achieved in that and below in conjunction with accompanying drawing the utility model is described further:

Its static structure: see also Fig. 1: as shown in the figure, novel telescopic fixed ruler of the present utility model.Mainly constitute by clamp 1, fixed head 2, spring 3, ruler 4.Clamp 1 adopts the screw fixing means to be installed in the position, next door of fixed head 2, constitutes " " combination of shapes structure, and function has been a fixation.Spring 3 adopts adhering method to be connected the position, next door of fixed head 2, constitutes integrative-structure, and function has been an elastic reaction.

Its dynamic structure: in force:

According to mechanics principle, its clamp 1 acts on fixed head 2 by spring 3, thereby finishes being installed of task.So just realized the purpose of this utility model.Can not be when drawing thereby just can solve the fixing problem of chi.

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

The novel telescopic fixed ruler of this utility model is work like this:

In use, when using chi, open clamp, be stuck in this next door.According to mechanics principle, its clamp 1 acts on fixed head 2 by spring 3, thereby finishes being installed of task.

Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of ruler factory, take to produce by batch in a large number, the demand with the supply daily life so just can realize practical value of the present utility model and economic worth better.

Claims

1. novel telescopic fixed ruler, it is to be made of clamp (1), fixed head (2), spring (3), ruler (4), it is characterized in that clamp (1) screw is fixedly mounted on the position, next door of fixed head (2).

2. novel telescopic fixed ruler according to claim 1 is characterized in that the bonding position, next door that is connected fixed head (2) of spring (3).
