Description

Structure improved tape measure

The utility model relates to the measurement mechanism in a kind of physical apparatus field, particularly relates to a kind of structure improved tape measure.

Present widely used tape measure, almost has only a kind of structural form on its structure, this structural form is to utilize tape measure after extraction, move down with clamping arc sheet, contacted the compacting tape measure and control the recovery strength of tape measure, to reach the purpose that fixing tape measure is measured, this structure is equipped with common composition element usually in design, see also shown in Figure 1ly, this tape measure wheel A is made up of band tpae sheet A1 and tape measure A2, and is embedded coating with loam cake B and bottom B1 by its two side; Worn fixingly by screw C, its clamping arc sheet D then is arranged at the leading edge place of loam cake B and bottom B1, forms the structure of removable adjustment, the location when extracting out with the tape measure A2 in the control band tpae sheet A1, and this structure can make the user reach the purpose of measurement easily usually; But when the user extracts tape measure A2 out, D carries out by press fit with clamping arc sheet, get final product measuring distance, every measurement once distance then must be carried out clamping arc sheet D is done the secondary action of pushing and breaking away from, sometimes then must be with the second-hand operation task that carries out, for the user, as if dislike numerous and diverse slightly, if measure repeatedly apart from the time, then can cause the defective of losing time to the user, and tape measure A2 and clamping arc sheet D long-term repeatedly by depressing, will inevitably produce elastic fatigue, in addition can produce clamping arc sheet D can't be completely effectively fixing tape measure A2, to such an extent as to make tape measure A2 measure the situation that a half has recovery, really make user's worry, must repeat to do the action of once extracting tape measure A2 out again, cause the inconvenience in the use.

Because the drawback of above-mentioned conventional tape measure, the design people is based on abundant practical experience and professional knowledge, through constantly studying, design, and after studying sample repeatedly and improving, creates the utility model finally.

Fundamental purpose of the present utility model is, overcome the deficiencies in the prior art, and provide a kind of structure improved tape measure, make it by palm control rubber-like friction pad, with the fixing band tpae sheet of palm control mode, and fix two kinds of modes by clamping arc sheet control, visual measurement situation is selected the fixed form of most convenient; And can freely control the size that applies press power, and can make the speed speed of band tpae sheet when reclaiming be able to effective control, reason does not reclaim power and makes the tape measure whipping when too strong and cause and damage or with personnel's injury, and have safe in utilization, reliable, can increase work efficiency and effect very easy to use.

The purpose of this utility model is realized by following technical scheme.A kind of structure improved tape measure, it comprises that the clamping arc sheet, of a tape measure wheel that is coated with tape measure, a compacting band tpae sheet coats the loam cake and the bottom of tape measure wheel and is contained in friction pad on loam cake, the bottom, it is characterized in that: this loam cake and bottom, its top, bottom respectively offer half slotted eye, and two side inner edges of half and half slotted eye are provided with half locating slot; This friction pad is arranged on half locating slot of aforementioned half slotted eye, and its bottom surface is provided with limited slip block; By applying pressure to friction pad, make limited slip block contact and compacting band tpae sheet, tape measure can't be rotated and the effect of location can be reached.

The purpose of this utility model can also further realize by following technical measures.Aforesaid structure improved tape measure, half slotted eye of wherein said loam cake and bottom, its half slotted eye that is positioned at the top is slightly long than half slotted eye of bottom.Aforesaid structure improved tape measure, the curved shape of wherein said friction pad, its top arch section is provided with the asperities face.Aforesaid structure improved tape measure, wherein said friction pad are the rubber-like elastic cushion block.Aforesaid structure improved tape measure, wherein said elastic cushion block is made by resilient material.

The utility model compared with prior art has tangible advantage and good effect.By above technical scheme as can be known, the utility model is a kind of steadiness of tape measure when extracting out that provide, and the new structure tape measure that can push firm band tpae sheet in the palm gripping simultaneously more is provided; It offers half slotted eye by top, bottom at loam cake and bottom, be provided with half locating slot in the inboard of half slotted eye minor face, so that after loam cake and the bottom combination, half and half slotted eye forms complete slotted eye, and the rubber-like friction pad is set in the slotted eye, can make its location by the packing band tpae sheet when pushing, by the use of friction pad, it has following several design features and advantage:

1. fix two kinds of modes by the fixing band tpae sheet of palm control mode, and by the control of clamping arc sheet, the situation of visual measurement is selected to use easily.

2. utilize palm control friction pad, can control the size that applies press power, make band tpae sheet its speed when reclaiming to control slowlyer, and form the effect that a buffering reclaims.

In sum, the structure improved tape measure of the utility model, it has except can gripping the band tpae sheet, the mode of can also palm pushing is controlled band tpae sheet, have safe in utilization, reliable, can increase work efficiency and effect very easy to use.Though it is easy structural design, but except convenience and high efficiency maneuverability, and can also control the measurement situation of tape measure effectively, be applicable to various use situation with assembling, thereby being suitable for practicality more, really is a new and innovative, progressive, practical new design.
