Abstract

The utility model relates to a band tape. The structure of a conventional band tape composed of an upper casing, a lower casing, a skeleton, a band tape belt torsion spring, a mandrel, a handle and a switch is additionally provided with a touch button for locking of segmental retraction of the band tape belt. The goal of locking the band tape belt through that the touch button abuts against the end surface of the skeleton. The band tape belt is retracted by a segment as long as the touch button is touched for one time. The utility model causes the people to have novelty, and good hand feeling in using process. The utility model adds a new species for the band tape product.

Description

Tape measure

The utility model relates to survey instrument, is the tape measure that a kind of linear measure longimetry is used specifically.

In routine work and life; the thing that needs to measure length dimension is run into by regular meeting, at this moment just need possess survey instrument, is the most frequently used with tape measure especially and measure in the length instrument; because of its have small and exquisite, can carry, can take advantages such as available immediately conveniently again, so liked by people.Usually the tape measure of structure all has the switch locking after its chi band is overhanging, in case off switch, the chi band will bounce back under the torsion spring effect automatically fast, but this structure often feels dull because of peace, and especially society enters economically developed today, people to the requirement of product commonly used except having minimum architectural feature, also require to be rich in the hope of good hand touch,, require chi to take back the compression process segmentation and carry out as tape measure, once bounce back one section, the other zestful of the heart sense that bounces back piecemeal with the feel touch.

The purpose of this utility model just provides the tape measure of a kind of chi band energy segmentation retraction locking, to satisfy the sensation of the good feel of people, feeling of freshness, good flavour.

By above-mentioned purpose, the utility model is realized by following scheme: by upper shell fastened to each other, be provided with the chi band that is wound on the skeleton in the chamber that lower house is formed, skeleton is sleeved on the mandrel, the inner connection of chi band end is inlaid in the torsion spring on the mandrel, the outer end Connection Card stays in the handle on the limiting plate of housing exit, the switch of locking chi band extension is located at, the lower house junction, cooperate the buckle of switch locking to be located at, the lower house inwall, it is characterized in that on housing, also being provided with the touch-button of chi band segmentation retraction locking, conflict on the skeleton end face after this button touch.

Described touch-button be outer ovalize, in the structure that is square, be arranged in the housing slotted eye.

The utility model possesses on the construction of switch basis that locks chi band extension original, set up the touch-button that can make the locking of chi band segmentation retraction again, promptly touch and once bounce back one section, make people that feeling of freshness, good feel and other zestful in use be arranged, also increased new varieties for the tape measure product.

Embodiment to the utility model is described in detail again below in conjunction with accompanying drawing.

Fig. 1 is the utility model perspective view.

Fig. 2 removes inner structure synoptic diagram behind the skeleton end face for upper shell.

Fig. 3 is the lower house structural representation.

As Figure 1-3, tape measure is by the upper shell (1) of injection mo(u)lding, the involutory back of lower house (2) the fastening one of screw, in its chamber, be provided with the chi band (5) that is wound on the skeleton (7), the inner torsion spring (8) that connects of chi band, the torsion spring end is inlaid on the mandrel (9) of fluting, mandrel is bearing in, in the supporting blind hole (14) of lower house, the handle (4) that connects chi band outer end blocks on the limiting plate (12) in housing exit, limiting plate and the clamping of housing exit, the switch (3) of locking chi band extension is located at, the lower house junction, this switch and an arc (13) disjunctor, cooperate the buckle (11) of switch locking to be located at, the lower house inwall, when after the chi band is overhanging, needing to lock, switch is down pushed away, the arc of switch is clamped on the chi band between the buckle and locked, after switch resets, and chi band retraction automatically under the torsion spring effect.

The utility model also is provided with the touch-button (6) of segmentation retraction locking, this button be outer ovalize, in the structure that is square, be arranged in the upper shell slotted eye, touching the back conflicts on the skeleton end face, the structure of touch-button can only push away it toward in and can not fall outward, when it is touched when conflicting on the skeleton end face, skeleton is promptly locked together with the chi band, loosen button, promptly remove resistance to skeleton, the chi band just bounces back under the torsion spring effect automatically, touches so repeatedly and just forms the segmentation retraction.

Easy to carry for making, in upper and lower casing, be provided with suspender belt post (10), to prick the knot suspender belt, button lobe (not shown) is set at the back side of lower house simultaneously, pass housing by screw and be fastened on the mandrel, not only be convenient to hang but also be convenient to insert and hung.
