Abstract

The utility model discloses a structure of a tape measure head hook. The tape measure head hook comprises a tape bonding part and a hook part, wherein, the surface of the tape bonded part is provided with a rivet hole which is penetrated by a rivet, so that the tape bonding part can be bonded with the surface of a tape; and a surface of the front end of the hook part is movably provided with an adsorption plate with a magnet or made of a magnet. The adsorption plate can be freely arranged on the hook part or be detached from the hook part. When the tape measure head hook is used, the hook part provided with the adsorption plate can extend the curve from the tape, and conveniently extend into a narrow space for surveying or adsorbing small iron parts and so on; and the adsorption plate can be detached from the head hook when the magnet on the adsorption plate is not used, so that troubles and inconvenience for a user because of the adsorption function of the magnet can be prevented.

Description

The structure of tape head hook

Technical field

The structure of a kind of tape head hook of the utility model, be meant that especially activity is equiped with an absorption sheet on a kind of this tape head hook, make the chi band that can make tape measure have the function of absorption, and in the time need not using magnet, also the absorption sheet freely can be taken off on tape head hook.

Background technology

Tape measure is very to have maneuverability and utensil easy to use in the survey instrument, as shown in Figure 1, existing tape measure 1, in shell 11, furl a chi bar 12 by elastic parts (figure does not show), one end of chi bar 12 is in conjunction with a tape head hook 13, this tape head hook 13 is incorporated into the chi bar with a stator 14 through rivet, and the in addition end of tape head hook 13 extends to form hook portion 15 downward vertically, by tape head hook 13 the chi bar is pulled out during use to measure.

Collude to function owing to should existing tape head hook 13 only possess, the situation that can't normally catch on takes place in regular meeting when running into remote the measurement, has influenced the correctness that measures.

In order to improve the problem that empty can collude extension, there is the dealer to propose to be provided with the conception of magnet in the tape head hook front end, No. 405703 employing is provided with embedded hole on tape head hook as the TaiWan, China patent announcement, and the mode of again magnet being inlayed this embedded hole combines with tape head hook; TaiWan, China patent announcement M258275 number then adopts and utilizes one to plug a surface with plug-in type and be inlaid with the slot that the fixture of magnet is reserved to the tape head hook front end, is formed in the function that the tape head hook front end is provided with magnet.

By above-mentioned two patent cases as can be known, utilization is at tape head hook front end installing magnet, make tape head hook and metal be measured thing when contacting, measured thing, increase hook that tape head hook and metal the measured thing qualitative improved direction of dealer that become that keeps steady with this by the magnetic absorption metal of magnet.

But above-mentioned two patent cases, its magnet cause when using other function for fixedly to be located on the tape head hook, can cause user's puzzlement and inconvenience because the adsorption function of magnet makes things such as adhering to unnecessary iron filings or iron piece on the tape head hook on the contrary.In addition, because magnet system fixedly is located on the tape head hook with rivet etc., so be the thickness that has increased tape head hook, also reduced the degree of accuracy when band tape measures.

The utility model content

Fundamental purpose of the present utility model, be to provide a kind of structure of tape head hook, be to be equiped with one movably to have magnet or whole be the absorption sheet of magnet on this tape head hook, make when the absorption sheet is installed in tape head hook, the chi band that can make tape measure is except measuring the length, the function that has absorption in addition, and in the time need not using magnet, also the absorption sheet can be disassembled on tape head hook, do not attach foreign material on it and can not cause, cause user's puzzlement and inconvenience because of the adsorption function of magnet.
