Description

Marking device and tape measure using the same Technical field

The present invention relates to the technical field of tape measures, and more particularly to a marking device and a tape measure to which the marking device is applied.

Background technique

As an easy-to-carry measurement tool, tape measure has become one of the must-have tools for workers in many industries. The existing tape measure usually consists of a one-foot box, a tape provided in the ruler box and a hub, the tape is wound on the hub, and the tape head has a bent tongue which is stuck at the mouth of the ruler box. outer.

When using a tape measure for measurement operations, the user often needs to mark the length of the measurement. Since the ordinary tape measure is not equipped with any additional mechanism that can be marked or crossed, the user must additionally mark it with a pen or Dashing, but in actual use, it is often not at hand, so the ordinary tape measure is often inconvenient to use.

Chinese Patent No. CN2593152Y (Patent No. ZL02286932.8) discloses a tape measure which can be simultaneously marked. The tape measure is provided with a long and narrow blind hole in the side wall of the ruler box, and a refill and a spring are arranged in the blind hole, and the root of the refill is pressed by the spring, so that the head of the refill always faces the periphery of the reel. The spring, the refill, and the circumference of the roller are all on the same line. When marking is required, the ruler box is moved, and the roller is rolled on the surface of the object to be measured, and the periphery of the roller is rubbed with the refill which is limited in the blind hole, thereby adhering the coloring material of the refill to the circumference of the roller. On the surface, the scrolling of the roller automatically leaves a mark on the surface of the object to be measured and becomes a mark such as a line.

It is not difficult to find that in the technical solution of the above patent, only one of the refills in the ruler can be set, which makes the use period of the marked function very limited; when the only refill is used up, we It is inferred (not disclosed in the above patent documents) that a new refill can only be added after the roller is removed from the ruler box. Such a replacement operation is very inconvenient; if it is done by a non-professional person, it is likely to be damaged. The ruler box, thus scrapping the entire tape measure, is obviously not suitable for actual needs.

Summary of the invention

The first technical problem to be solved by the present invention is to provide a marking device which is easy to add a coloring material, has an unrestricted use period, and is more suitable for practical use in view of the current state of the art.

A second technical problem to be solved by the present invention is to provide a tape measure to which the above marking device is applied.

The technical solution adopted by the present invention to solve the above first technical problem is: a marking device comprising a box body with an open bottom and a rotatable rolling member disposed at the bottom of the box body, a part of the circumferential surface of the rolling element is exposed In addition to the bottom of the box body, the box body is provided with a coloring material above the rolling element, and is further disposed above the coloring material. A pushing mechanism for pushing the colored material to keep it pressed against the rolling member is provided.

Preferably, the pushing mechanism comprises an elastic member and a pressing block disposed in the casing, the bottom of the pressing block pressing the top surface of the coloring material, and the two ends of the elastic member respectively abut against the pressing block and the inner side of the top of the casing.
