Abstract

An abrasion resistant flexible rule comprises a rule box (1) and a rule belt (6) arranged inside the rule box, wherein, the rule box (1) is provided with a stop block (4) at the opening part; the bending tongue piece at the front portion of the rule belt (6) is clamped at the front end of the stop block (4) at the end of furl. The utility model is characterized in that: the end face of the stop block (4) opposite to the reverse of the rule belt (6) is provided with a metallic wearable sheet (5); the stop block (4) is better to adopt a winding folded structure with the side view being in the shape like the Chinese character ''gong''; the wearable sheet (5) can be striken out with a bending sheet (51) embedded into the corresponding eyelet (41) on the stop block (4) to make both connected together. Compared with the prior art, the utility model has the advantages that: the rule belt (6) no longer directly rubs against the stop block (4), but against the metallic wearable sheet (5) arranged on the end face of the stop block (4), thereby effectively protecting the opening of the rule box.

Description

A kind of durable anti-wear tape measure

Technical field

The utility model relates to a kind of tape measure, particularly a kind of durable anti-wear tape measure.

Background technology

Existing tape measure includes chi box and interior chi band thereof; the chi tape wrapping is on the interior winding stand that wind spring arranged; the chi box of can be under the effect of wind spring after the chi band is drawn out withdrawing automatically with the revolution of winding stand; bending tongue piece until chi band head is stuck on the ruler box mouth; when reality is used; when chi is taken back the retraction box; under inertia effect; chi band tongue piece can cause certain impact to ruler box mouth; service time one, therefore long ruler box mouth also possible and damaged; for this reason; the tape measure that block is set or protects mouth at ruler box mouth is devised; thereby play the effect of protection ruler box mouth; yet because these blocks all were rigidity in the past, so chi takes back volume and at the end still can bring certain vibrations to the impact that ruler box mouth caused, and therefore the user can not feel well; to this, have in the commercially available tape measure and adopt the block of flexible material to reach certain damping effect.And utility model patent ZL01245740.X number " a kind of Shock-absorbing tape " (notification number CN2482046Y) that I formerly propose provides a kind of better solution, it is by being provided with a block that has elastic buffer structure on chi band direction at ruler box mouth, make the chi band in backrush when at the end the bending tongue piece of its head impacts this block, absorb, cushion a certain amount of impact by this block, thereby reduce the vibrations of chi box effectively.However no matter design that the material of block is that rigidity or flexibility all have damping effect preferably, but, be good still to choose comparatively soft material in order to make block have good absorbing vibration ability.Yet, adopt the block of flexible material to bring another problem, promptly because therefore the chi band metal material of rigidity (being generally steel matter) often can cause wearing and tearing to this block when flexible.

Summary of the invention

Technical problem to be solved in the utility model is the tape measure that a kind of ruler box mouth belt wear of anti-the chi is provided at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this durable anti-wear tape measure includes chi box and interior chi band thereof, the chi box is provided with a block at oral area, the chi band backrush at the end the bending tongue piece of its head be stuck in this block front end, it is characterized in that: described block and chi band back side opposing end faces are provided with the wear plate of metal material.

Described block is good with the winding foldable structure that side-looking is " bow " font, to have better damping, surge capability.

Described wear plate can be bonded on the block, also can be mounted on the block, better, can be by making both connect one going out bent sheet on the wear plate and embed on the block corresponding aperture.

Compared with prior art, advantage of the present utility model is that the chi band no longer directly rubs with block, and with the abrasion-resistant metal sheet generation direct friction that is arranged on the block end face, thereby protected ruler box mouth effectively.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, durable anti-wear tape measure includes chi box 1 and is positioned at it, is wound on the chi band 6 on the winding stand 3, chi box 1 is provided with a block 4 at oral area, chi band 6 backrush at the end the bending tongue piece of its head be stuck in this block 4 front ends, described in the present embodiment block side-looking is the winding foldable structure of " bow " font;

Referring to Fig. 3～shown in Figure 6, described block 4 and chi band 6 back side opposing end faces are provided with the wear plate 5 of metal material; In the present embodiment, described wear plate 5 has two bent sheet 51 in the medium position upper punch, and embeds aperture 41 corresponding on the block 4 and make both connect one.

Claims

1, a kind of durable anti-wear tape measure, include chi box (1) and interior chi band (6) thereof, chi box (1) is provided with a block (4) at oral area, chi band (6) backrush at the end the bending tongue piece of its head be stuck in this block (4) front end, it is characterized in that: described block (4) and chi band (6) back side opposing end faces are provided with the wear plate (5) of metal material.

2, tape measure according to claim 1 is characterized in that described block (4) has the winding foldable structure that side-looking is " bow " font.

3, tape measure according to claim 1 and 2 is characterized in that going out bent sheet (51) on the described wear plate (5) and embeds block (4) going up corresponding aperture (41) and making both connect one.
