CN201165135Y - Adhesive tape straight ruler - Google Patents

Abstract

The utility model relates to an adhesive tape ruler, which arranges two gaps at the symmetrical positions of the two side faces of the ruler; the thickness of the ruler face between the two gaps is less than that in other positions, so that a concave structure is formed; the concave position is enwrapped with transparent adhesive tape; a circular opening is arranged on the surface of the ruler; a convex lens is arranged at the opening. When using the adhesive tape, the user needs to tear down the transparent adhesive tape from the concave surface of the ruler; as the ruler face has a concave surface, the thickness of the ruler can not be affected after the adhesive tape is enwrapped in the concave surface; during reading or writing, the user can enlarge images through the convex lens to strengthen the observation results. The adhesive tape ruler has the advantages of simple structure, beautiful shape and novel functions, and is convenient and practical.

Description

The adhesive tape ruler

Technical field

The utility model relates to a kind of linear measure longimetry, drawing tool, especially a kind of adhesive tape ruler.

Background technology

As everyone knows, ruler is one of most important instrument in people's study and work.But present ruler function ratio is more single, can only measure or draw straight line, can't provide other help for people.For this reason, we provide a kind of new-type ruler of subsidiary adhesive tape certainly will be subjected to liking of people.

Summary of the invention

The purpose of this utility model provides a kind of adhesive tape ruler, is used to solve common ruler function simple question.

For achieving the above object, the utility model adhesive tape ruler comprises the bar shaped ruler, and symmetric position is offered gap in the ruler two sides, and the chi face thickness between two gap forms concave structure less than other position thickness, twines adhesive tape in the concave surface position; Offering circular open on the ruler surface, is convex lens at opening part.

After adopting said structure, the user can normally use ruler to measure or draw straight line.When using adhesive tape, need be from the chi face concave surface adhesive tape of tearing, because the chi mask has concave surface, can not influence the chi face thickness after twining adhesive tape; In addition, in seeing the written word process, the user also can utilize the amplification of convex lens to come enlarged image, strengthens observing effect.

The utility model has the advantages that: simple in structure, convenient and practical, good looking appearance, function are peculiar, also scalable image, and can carry adhesive tape, the service condition of providing convenience for people.

Description of drawings

Fig. 1 is the overall structure schematic diagram of the utility model adhesive tape ruler.

The specific embodiment

As shown in Figure 1, the utility model adhesive tape ruler comprises bar shaped ruler 1, offers chi face thickness between 2, two gap 2 of gap less than other position thickness in ruler 1 two sides symmetric position, forms concave structure, twines adhesive tape 3 in the concave surface position; Offering circular open on ruler 1 surface, is convex lens 4 at opening part.

Claims (1)

1, a kind of adhesive tape ruler, comprise bar shaped ruler (1), it is characterized in that: symmetric position is offered gap (2) in ruler (1) two sides, and the chi face thickness between two gap (2) is less than other position thickness, form concave structure, twine adhesive tape (3) in the concave surface position; Offering circular open on ruler (1) surface, is convex lens (4) at opening part.
