Abstract
The invention is a kind of measuring tape whose tape belt can be retracted flexibly. It includes a box and a tape belt. In the box, the tape belt is winded on a spiral bracket, the bracket is fixed on the centre pile set in the centre of the box side wall through the centre hole on the two side walls, there sets a twisting spring in the space between the centre pile and the twisting bracket, the character lies in: the mentioned twisting bracket sets a bearing between the outer surface of the box and the inner side wall. The bearing also can set between the twisting bracket and the centre pile. Compared with current technology, the invention changes the sliding friction into rolling friction, the friction is decreased greatly, thus the retraction of the tape belt is more flexible.
Description
Technical field
The present invention relates to a kind of tape measure, the folding and unfolding of particularly a kind of chi band is tape measure flexibly.
Background technology
Existing tape measure has generally comprised box body and chi band, the chi tape wrapping is on a hub-like winding stand in box body, the bending tongue piece of chi band head then is stuck in outside the box body port, the inner chamber of winding stand then is provided with wind spring, the side direction that is fixed on the initiating terminal of wind spring runs through winding stand center pit end and then is fixed on the newel of housing sidewall, the end finally of wind spring then is fixed on the winding stand, two lateral walls of the winding stand outer rim in heart hole therein have convex annular wall, and pine is enclosed within the housing madial wall on the cylinder boss of corresponding position setting respectively.When the chi band is drawn out, relatively rotate between the side convex annular wall of winding stand and the cylinder boss of housing, wind spring is tightened up, when loosening the chi band, under the restoring force effect of wind spring, the winding stand backward rotation also is wound on the winding stand chi band withdrawal box body again.Owing to when relatively rotating, have sliding friction between the side convex annular wall of winding stand and the cylinder boss of housing, therefore, in at chi band broad, than long large-scale tape measure, the folding and unfolding of chi band is owing to the existence of friction force seems dumb, and the also necessary preferred dimension of wind spring is bigger, so that enough restoring forces to be provided, this can cause the overall dimension of tape measure to increase, and makes outward appearance seem heavy.
Summary of the invention
Even technical matters to be solved by this invention is that also folding and unfolding tape measure flexibly of a kind of broad, long chi band is provided at above-mentioned prior art present situation.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: this chi band folding and unfolding tape measure flexibly includes box body and chi band, in box body, the chi tape wrapping is on a hub-like winding stand, winding stand then is bearing in two ends by the center pit on its two sidewall and is fixed on the newel of box side wall central authorities, between the perisporium of newel and winding stand, be provided with wind spring, it is characterized in that described winding stand is provided with bearing between lateral wall and the corresponding box body madial wall at least therein.
Described bearing can be provided with in the following manner: described winding stand is provided with convex annular wall in the outer rim of the contiguous center pit of its lateral wall, the box body madial wall then is provided with cylinder boss in the corresponding position, described bearing promptly is arranged between the cylinder boss of the convex annular wall of winding stand and box body, its outer ring is embedded on the convex annular wall of winding stand, and its inner ring then is fixed in outside the cylinder boss of box body.
Described bearing also can be arranged between winding stand and the newel, can be provided with in the following manner: described winding stand is provided with convex annular wall in the outer rim of the contiguous center pit of its lateral wall, described bearing promptly is arranged between the convex annular wall and newel of winding stand, its outer ring is embedded on the convex annular wall at winding stand, and its inner ring then overlaps outside the solid newel.
Compared with prior art, the present invention is owing to be provided with bearing between between the lateral wall of winding stand and box body madial wall or the newel, make the friction that is produced when relatively rotating between them change rolling friction into by sliding friction, friction force significantly reduces, thereby make the folding and unfolding of chi band more flexible, even chi band broad, the large-scale tape measure of growing also need not be selected large-sized wind spring for use.

Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, this chi band folding and unfolding tape measure flexibly includes box body 1 and chi band 2, in box body 1, chi band 2 is wound on the hub-like winding stand 3,3 of winding stands are bearing in two ends by the center pit on its two sidewall and are fixed on the newel 6 of box body 1 side wall centers, are provided with wind spring 5 between the perisporium of newel 6 and winding stand 3;
Described winding stand 3 is provided with bearing 4 between its lateral wall and corresponding box body 1 madial wall, promptly, described winding stand 3 is provided with convex annular wall 31 in the outer rim of the contiguous center pit of its lateral wall, box body 1 madial wall then is provided with cylinder boss 11 in the corresponding position, described bearing 4 promptly is arranged between the cylinder boss 11 of the convex annular wall 31 of winding stand and box body, its outer ring 41 is embedded on the convex annular wall 31 of winding stand, and its inner ring 42 then is fixed in outside the cylinder boss 11 of box body.
In embodiment one, 4 on described bearing is arranged on one of them lateral wall of winding stand 3, if but actual needs also can be simultaneously be provided with same bearing 4, embodiment two as shown in Figure 3, Figure 4 between the corresponding madial wall of another lateral wall of winding stand 3 and box body 1.
As Fig. 5, shown in Figure 6, be enforcement three of the present invention, different is with embodiment one, two, described bearing 4 is arranged between winding stand 3 and the newel 6, that is, described winding stand 3 is provided with convex annular wall 31 in the outer rim of the contiguous center pit of its lateral wall, and described bearing promptly is arranged between the convex annular wall 31 and newel 6 of winding stand, its outer ring 41 is embedded on the convex annular wall 31 at winding stand, and its inner ring 42 then overlaps outside the solid newel 6.
In the above-described embodiments, the design of the convex annular wall 31 of described winding stand is to be used for forming a recessed space to hold bearing 4, if the thickness of winding stand 3 is enough, can directly be a shrinkage pool also, and concrete figure slightly.
