CN201208857Y - Folding rule - Google Patents

Abstract

The utility model discloses a folding ruler comprising a ruler body which is composed of two half rulers, the middle parts of the two half rulers are respectively provided with a hinged part, the two hinged parts are round and respectively provided with a round hole in the middle, and the two hinged parts are superposed together and rotationally connected together through a pivot shaft. The folding ruler provided by the utility model can keep same as the traditional ruler to work out the length of a straight line and measure the length.

Description

A kind of folding chi

Technical field

The utility model relates to a kind of stationery, relates in particular to a kind of ruler of being made by hard material, thereby this chi can fold from the centre and reduces to collect needed space.

Background technology

Ruler is a kind of stationery commonly used, and it is normally made by a kind of harder material, such as plastics, metal, timber or the like.This ruler all has certain length, so that the user is used for picture straight line or as the length measurement facility.But bring the inconvenience of carrying but have certain length, such as the size of user's bag or pocket the time, just the collection space deficiency time, carry and just become very inconvenient less than the length of ruler.

Summary of the invention

Technical problem to be solved in the utility model provides a kind ofly can draw longer straight line and as the measurement facility of length but can use the folding chi in less space during collection.

In order to solve this technical problem, the utility model provides a kind of collapsible chi, it includes a blade, blade is made up of two and half chis, in the middle of two and half chis articulated section is arranged respectively, two articulated sections are rounded, and respectively there is a circular hole centre, two articulated sections overlap, by rotating linking together of pivot of passing the articulated section circular hole.

The beneficial effect that the utility model brought is under the constant condition of drawn straight length, makes the length of the collection requisite space of ruler dwindle half.

Description of drawings

Fig. 1 is the schematic side view of the utility model preferred embodiment.

The specific embodiment

Figure 1 shows that the schematic side view of the preferred embodiment of a kind of folding chi of the utility model.This chi includes a blade 1, blade 1 is made up of two and half chis 10,20, an articulated section 11,21 (articulated section 21 is overlapping with articulated section 11 among the figure) is respectively arranged in the middle of two and half chis 10,20, two articulated sections 11,21 are rounded, respectively there is a circular hole (not shown) centre, two articulated sections 11,21 overlap, by a pivot 30 rotating linking together.

When using during at needs picture straight line or as the length measurement facility, the user can break into two with one's hands until the upper limb of two and half chis 10,20 two and half chis 10,20 in alignment.And when the user need collect ruler, it can rotate two and half chis 10,20 in opposite directions until two and half chis 10,20 around pivot 30 and also arrive together.

As shown in Figure 1, can have one respectively in the end portion of two and half chis 10,20 protrudingly buckles 12 and one and recessedly buckles 22.At two and half chis 10,20 and to a time-out, protruding button 12 can be inserted among the recessed button 22, rely on the frictional force of protruding button 12 between recessed button 22 to make and to two and half chis 10,20 relatively be not easy to separate.Protruding button 12 can also have a bigger head, and recessed button 22 also can have an oral area that receipts are little.

Can see that from the above description folding chi provided by the utility model can reduce half with the length of collection requisite space when keeping the identical length that can make straight line and measuring length with traditional ruler.

Known to those skilled in the art, drawings and Examples of the present utility model are only for illustrating that function of the present utility model, structure and principle should not become the restriction in the utility model understanding; Simultaneously, the purpose of this utility model all realizes.The foregoing description may be had some change under the situation that does not break away from the utility model principle, so protection of the present utility model should be as the criterion with the scope described in claims.

Claims (4)

1. collapsible chi, it is characterized in that including a blade 1, described blade 1 is made up of two and half chis 10,20, in the middle of described two and half chis 10,20 articulated section 11,21 is arranged respectively, described two articulated sections 11,21 are rounded, respectively there is a circular hole centre, and described two articulated sections 11,21 overlap, by pivot 30 rotating linking together of passing the described circular hole in articulated section.

2. collapsible chi as claimed in claim 1 is characterized in that end portion at described two and half chis 10,20 has one respectively and protrudingly buckles 12 and one and recessedly buckle 22.

3. collapsible chi as claimed in claim 2 is characterized in that described protruding button 12 has a bigger head.

4. as claim 2 or 3 described collapsible chis, it is characterized in that described recessed button 22 has one and receives little oral area.
