The utility model relates to an improved flexible rule head hook which is provided with a combining part fixedly connected with the rule, wherein the surface of the combining part is provided with a rivet hole combined with the rule, and a hook part for positioning a measured object. A groove for holding a magnet is formed outside the hook part, and the shape of the groove is the same as that of the contacting surface of the magnet. The magnet is combined with the hook part in an adhesive mode, and the utility model is convenient to manufacture and use.

Description

Improved tape head hook

Technical field

The utility model relates to the parts of measuring appliance, specifically, is a kind of improved tape head hook.

Background technology

Tape measure be a kind ofly be widely used, measuring appliance easy to use.Tape measure commonly used generally is made of the chi bar of a housing and content, the flexible member or the scrolling handle that also have the footage bar to use, and the tape head hook that is positioned at the tape measure front end, combines with the chi bar.Tape head hook have one with the joint portion of chi bar riveted joint, also has a hook portion that forms by the joint portion extension, retaining was at the chi bar opening part of housing when hook portion can be in tape measure retraction housing, in order to avoid in the complete retraction shell of chi bar, on the other hand, during measurement, can spur this tape head hook, catch on measured perpendicular face with hook portion and carry out to pull out tape measure.

The tape head hook of said structure has been continued to use for many years, because of it only possesses the function of colluding, needs telemeasurement and measured object not to have the position and can collude when hanging, can produce the problem of measuring error, this not only influences the accuracy of measurement, also needs other people conjunction measuring person to measure, and uses quite inconvenience.

There is not the problem that extension can be colluded in the position for improving measured object, someone proposes to collude the conception that front end is provided with magnet at the chi head, collude at the chi head embedded hole is set, again with magnet to combine with mode that this embedded hole is inlayed, but this structure at tape head hook front end arrangement magnet is too complicated, has not only increased the weight of tape head hook, influences the smooth-going of tape measure folding and unfolding, also have the caducous problem of magnet, make and make and use all inconveniences.

Summary of the invention

Fundamental purpose of the present utility model provides a kind of improved tape head hook simple, easy to use of making;

Another purpose of the present utility model provides a kind of improved tape head hook of being convenient to collude with the vertical plane of tested surface grip.

For achieving the above object, the utility model provides improved tape head hitcher that one joint portion of fixedlying connected with the chi bar is arranged, the surface, joint portion is provided with the riveted holes in conjunction with the chi bar, also has a hook portion that is used for the measured object location, the hook portion outside is provided with magnet, and that the hook portion surface has is identical with magnet surface of contact shape, settle the groove of usefulness for magnet.

By above scheme as seen, because the utility model adopts magnet is placed in version in the hook portion surface groove, structure is simple relatively, and weight also can be lighter relatively, gives to make and use and all brought convenience.

Fixing between magnet and tape head hook can be adopted multiple mode, and more excellent selection is to be equipped with one deck sticker between magnet and described groove, is realized by bonded structure.

For prevent that to greatest extent magnet from coming off in measuring process, the groove of settling magnet to use can be arranged on the front end surface of hook portion.

For improving the grip of hook portion and measured object, more excellent scheme is to settle on-slip rubber at the back side of magnet placement surface.

Fig. 2 is the structure cut-open view of first embodiment;

Fig. 3 is the structure cut-open view of second embodiment;

Fig. 4 is the structure cut-open view of the 3rd embodiment.

Be described further below in conjunction with each embodiment and accompanying drawing thereof.

Embodiment

First embodiment:

Referring to Fig. 1, Fig. 2, this tape head hook 1 comprises a joint portion 2 and a hook portion 3, and joint portion 2 adopts the same metal material to be made into integration with hook portion 3.The surface of joint portion 2 is provided with two riveted

holes

21,22, is incorporated into chi bar surface in order to pass rivet 23,24; Hook portion 3 outsides are provided with two

magnets

4,5,

magnet

4,5 is for being the right cylinder of flat, be fixed in the surface of hook portion 3 and be provided with the magnet tool identical shaped and can hold the

groove

31,32 of magnet, make

magnet

4,5 can be fast and hook portion 3 form one, and, between

magnet

4,5 and

groove

31,32, fill out and be provided with one deck sticker 6, fix with the adhesion that adds

kicker magnet

4,5 and

groove

31,32.

See through the use setting of sticker 6 and

groove

31,32,

magnet

4,5 can closely be adhered with hook portion 3, and this is quite convenient for the fabricator, as long as make respectively in advance, being adhered fast to install by operating personnel then gets final product, and can avoid prior art to need the inconvenience of tool using assembling.The user also can use the

magnet

4,5 that is provided with at hook portion 3 front end faces, overcomes the inconvenience of telemeasurement, need not other people and is used.In addition, because tape measure can freely stretch, also can be in order to pick up micro metal article such as the tiny metal object (for example clip) that drops on zanjon or deep gully place or key, all suitable aspect.

Second embodiment:

Referring to Fig. 3, this example is different with first embodiment to be in hook portion 3 except providing magnet 4 with the groove on its

front end surface

6,5 be provided with outside, surface, its rear end also is formed with rearward recess 7, insert the flexible on-slip rubber 8 of tool in the rearward recess 7 again, on-slip rubber 8 can be close type with rearward recess 7 or adhesion-type combines, and after on-slip rubber 8 is inserted rearward recess 7, outwards protrude about 0.1mm, when providing hook portion 3 back sides paste to support tested article thus, the design feature of on-slip rubber 8 tool elasticity and protrusion, reach hook portion 3 back sides and pasted to measured object fully and be that non-light face contacts, increase the grip between hook portion 3 back sides and measured object with measured object.

The 3rd embodiment:

Referring to Fig. 4, what this example was different with second embodiment is, when the plate face of hook portion 3 approaches, provide groove 6 to have in limited time with the thickness that

magnet

4,5 is set, rearward recess 71 also can be arranged on the below of hook portion 3, and promptly rearward recess 71 is located at the below of groove 6, inserts the on-slip rubber 81 of tool elasticity in the rearward recess 71 again, can reach hook portion 3 back sides equally and be pasted to article fully and be that non-light face contacts, increase the grip of hook portion 3 back sides and article with article.

The various embodiments described above only are used for the understanding to the utility model design, it is not qualification to the utility model design, conceive according to the utility model, the simple change that some tape head hook structures also can be arranged, as for further alleviating the weight of tape head hook, can also adopt the version that is coated with one deck non-skid coating at the back side of hook portion 3 to improve the grip of hook portion 3.
