Abstract

The utility model discloses an improved ulnar head hook of a tapeline. The ulnar head hook has a button element and a stator perpendicular to the button element, wherein the back end of the stator is connected with a tapeline belt, the front end of the stator forms a rabbet which is tenoned with a vertical film threading, the film threading is used to insert a central button slice of the button element and is articulated with one clampingpiece in the button element through a pivot. Therefore, the button element forms can change the position of the button according to different places, thus being convenient for measurement.

Description

Modified tape head hook

Technical field

The utility model relates to a kind of tape head hook structure, is meant that especially a kind of snap device of tape head hook front end that makes can turn snapped-in position in response to different places, to reach the utilization again that is convenient for measuring and provides the chi bar back side.

Background technology

Tape measure is very to have maneuverability and utensil easy to use in the survey instrument.As shown in Figure 1, known tape measure B generally is accommodated in the housing C by the flexible member (not shown), and be combined with a tape head hook A in the end of tape measure B, this tape head hook A is provided with a stator A1 for the end of being fixed in tape measure B by rivet, and extended a hook portion A2 by tape head hook A, kept off the opening part of pulling in housing C can be in tape measure B retraction housing C the time to avoid in the complete retraction housing of the tape measure B C by this tape head hook, then can spur this tape head hook A during use to pull out tape measure B, tape head hook A button is against the vertical plane of article to measure.

Yet tape head hook A has continued to use for many years though these are commonly seen, and still has suitable shortcoming in the use, is described as follows now:

At first, the hook portion of this tape head hook in order to constitute the one sense with tape measure, and causes the inconvenience of carrying for avoiding because of too protruding at the beginning of design, and the area of this hook portion A2 needs to control as best one can to dwindle.But because tape measure is when measuring, be with this hook portion as colluding the anchor portion of holding object, after it was fixing, tape measure just can move the user and extend elongation down, and then measures distance.And the too small result of hook portion area but causes powerful danger of rebounding after the slippage easily.

Secondly, because the hook portion of tape head hook is only extended to single direction, this kind is construed as limiting tape measure only can hold measurement to the single direction hook, can't use when running into the corner or have only the opposite direction flange, causes the inconvenience in the use.

Moreover the hook portion of tape head hook makes the back side of band tape not have the part of useing force to the result that single direction extends, and also limits its usability.

Summary of the invention

Because there is above-mentioned shortcoming in known tape head hook, the utility model designer is studied, is improved, and through repeatedly testing generation of the present utility model is arranged eventually.

Therefore, the utility model promptly aims to provide a kind of modified tape head hook, and according to this kind tape head hook of the present utility model, the snap device of order formation chi head scratching part position can be adjusted to change to collude in good time and hold position and angle, improves and uses elasticity.

According to this kind modified tape head hook of the present utility model, can turn by snap device, make the band tape back side also can indicate numerical scale, with the usefulness as the ruler measurement, this is an of the present utility model purpose.

According to this kind modified tape head hook of the present utility model, can turn by snap device, can utilize the curved arc shape back side of band tape docile to the Measuring Object surface, to be convenient for measuring and to rule sign, this is a purpose more of the present utility model.

For achieving the above object, the technical solution adopted in the utility model mainly is: a kind of modified tape head hook, this tape head hook, comprise a stator, an inserted sheet and a snap device, this stator rear end forms several fixed orifices and is incorporated into the chi band with mat rivet or other retaining elements, its front end embeds and is vertical inserted sheet with it, and the mat inserted sheet is pivotally arranged on snap device, and reaching snap device can be that the axle center rotates according to pivot.

Below in conjunction with drawings and Examples, structure of the present utility model and advantage thereof are further described.

Embodiment

This kind modified tape head hook of the present utility model, shown in Fig. 2, Fig. 3 A, Fig. 3 B, this tape head hook 1, comprise a stator 11, an inserted sheet 12 and a snap device 2, these stator 11 rear ends form several fixed orifices and are incorporated into the chi band with mat rivet or other retaining elements, its front end central authorities form recess 13, front-end edge also forms spaced two tenons 14, for embedding the upright inserted sheet 12 that is vertical configuration with it, this upright inserted sheet 12 slightly becomes horizontal rectangular body, its central authorities establish riveted holes 15, and its both side edges also forms the draw-in groove 16 that caves inward.

2 of this snap devices comprise forward and backward

intermediate plate

3,4 and middle cramp 5, front and back

intermediate plate

3,4 front and back clamping cramps 5 are formed one mutually with rivet again, preceding intermediate plate 3 surfaces are formed with arc-shaped slot 31, cramp 5 surfaces also form corresponding, and be formed with a semicircular arc clip 51 in arc-shaped slot 50 upper ends, clip 51 two ends respectively form

buckle ear

52,53, after inserted sheet 12 inserts from top to bottom, in order to embed the draw-in groove 16 of inserted sheet both sides; 15 of the riveted holes of these inserted sheet 12 central authorities supply mat pivot 17 and rear jaw 4 to articulate, and then provide snap device 2 to do the unspecified angle rotation according to the centrally-pivoted axle 17 of inserted sheet 12 for the axle center.

Shown in Fig. 4 A, Fig. 4 B, snap device 2 since its central authorities establish one with the inserted sheet 12 of stator 11 riveted joint, and inserted sheet 12 articulates with rear jaw 4, therefore, it can rotate for the axle center according to centrally-pivoted axle 17.That is, the position of its buckle can be changed up and down, can need and adjust at different places.

Shown in Fig. 5 A, Fig. 5 B, when the utility model is combined in tape measure 7, can rotate by this snap device 2, can measure at the surface of body 71 to be measured, or the lower end of body to be measured measures, and for example desktop lower end or dark corner are perhaps during the wall edge of different azimuth, all can adjust use, can not be subjected to the restriction of field of employment again.

And, as shown in Figure 6, because snap device 2 can be done 180 degree upsets, it no longer is subject to the restriction that traditional chi band upper end face is curved arc shape, promptly also can indicate the ruler scale at the chi band back side 72, when snap device 2 counter-rotating collude hold body to be measured after, can utilize male bend arc chi edge, the chi band back side 73 to paste and support to surface to be measured, make the gage range finding or the line of drawing convenient and certain.

Shown in Fig. 7, Fig. 8 A, Fig. 8 B, the improvement tape head hook of this kind structure of the present utility model, the middle cramp of its snap device 2, also can make clip is separate type clasp 6, directly be embedded into by separate type clasp 6 on the central arc-shaped notch 61 of cramp, also can reach the revolvable effect of aforementioned snap device.

In sum as can be known, the improvement tape head hook of this kind structure of the present utility model, its snap device by tape head hook can appropriateness rotate, and can adjust hook in response to object under test in good time and hold the position, can effectively improve the safety of use, improve the shortcoming of the tape head hook of commonly seeing really.

Palpus Chen Ming; the above textural association is the preferable specific embodiment of the utility model, if comply with the change that conception of the present utility model is done, the function of its generation; when not exceeding instructions yet and illustrating contained spiritual, all should be included in the protection domain of the present utility model.
