Abstract
The utility model relates to an improved band tape of a brake mechanism, which comprises a shell, a spring belt and a brake pressing key. A sliding chute, an inlet and an outlet of a band tape strip are arranged on the shell, wherein, the center of which is provided with a fixed axle of the spring belt, and the outside of the spring belt is provided with a wound band tape strip. The inner face of the shell adjacent to the outlet of the band tape strip is provided with a cushioning body made of quite flexible and elastic materials, and friction force can be increased by tying the cushioning body. When a brake key is downward pushed, the band tape strip can be clamped by the utility model and an oppressing end on the top surface of the band tape strip corresponding to the brake pressing key together, and the pulled out length of the band tape strip can be fixed. When the brake key is pushed upward, the band tape strip is retracted, the cushioning body is rubbed with the band tape strip, the speed of the band tape strip is decelerated, and a user's born shock and harm can be reduced.
Description
The utility model relates to tape measure, and particularly a kind of have a tape measure that can make the fixing brake of tape strip under the situation that need not apply very big strength.
The tape measure of commonly seeing, as Fig. 1 and Fig. 2 A, shown in the 2B, by housing 11, brake button 12, tape strip 13, spring band 14, rolling wheel 15 members such as grade are formed, shown in Figure 1A, the braking mechanism of tape measure is made of the outlet bottom 111A of brake button 12 and housing 11, the pressure side, bottom 121 and tape strip 13 separated attitudes of brake button 12, so tape strip 13 can freely be pulled out or rollback, shown in Fig. 2 B, when the user will brake button 12 after chute below place's promotion of housing with thumb, the pressure side, bottom 121 of brake button 12 is about to tape strip 13 end faces and tightly props up, and makes tape strip 13 bottom surfaces 111A bottom the housing outlet contact and fix; But, the housing 11 of tape measure all is to use hard material with brake button 12, make as plastic cement, bakelite, metal etc., when brake button 12 is pushed downwards, the pressure side, bottom 121 and tape strip 13 end faces of brake button 12, and the friction force between tape strip 13 bottom surfaces and the housing outlet bottom 111A is little, and because of tape strip 13 often is subjected to the effect of the power of spring band 14, causes tape strip 13 still to be subjected to being difficult to fix by the effect of the power of rollback when brake.
Because housing 11 is the flexible hard material of tool not, it is offered an opening 111 and comes in and goes out for tape strip 13, the housing 11 of opening periphery also is the identical flexible material of not tool, thus, when tape strip 13 rollbacks, the iron of being located at the tape strip front end colludes sheet 131 because of the epistasis return force function of spring band 14 shell nozzle 111 of thumping, and causes the user and is difficult for gripping, even injured because of the rollback of tape strip 13, cause the inconvenience in the use.
The purpose of this utility model aims to provide the improved tape measure of a kind of braking mechanism, when tape strip is pulled out, need not to press under the situation of tape strip and also can like a cork tape strip be fixed, when making the tape strip rollback, can not cause bump to user's hand, also can be because of the impulse force folder of quick rollback
Hinder the user.
The utility model is achieved in that improved tape measure braking mechanism, includes housing, spring band and brake button, and housing is provided with chute and tape strip is imported and exported, and its central authorities are provided with the spring band stationary shaft, and the spring band outside is provided with the tape strip of coiling; The housing inner face is provided with one downwards when the brake button pushes away near the tape strip exit, can clamp the flexible buffer body of softer and tool of tape strip with the brake button to the pressure side of tape strip end face.
The utility model with described structure, owing to be provided with one downwards when the brake key pushes away near the tape strip exit at the housing inner face, can clamp the flexible buffer body of softer and tool of tape strip with the brake button to the pressure side of tape strip end face, thereby braking mechanism is to the friction force of tape measure when having strengthened the tape strip folding and unfolding, when tape strip is pulled out, can under the situation that is not subjected to powerful compacting, can be fixed in the Len req place like a cork; When the tape strip backrush, because buffer body has absorbed the part kinetic energy of tape strip, the rollback speed of having slowed down tape strip can reduce its gripping hand to the user and be given a shock and injure.
The following drawings and embodiment will be described further technical characterictic of the present utility model:
Fig. 1 is the synoptic diagram of tape measure of commonly seeing.
Fig. 2 A be commonly see the tape measure structure sectional view.
Fig. 2 B is the tape measure structure action back sectional view of commonly seeing.
Fig. 3 A is the preceding sectional view of the utility model tape measure brake.
Fig. 3 B is the sectional view after the utility model tape measure brake.

Embodiment: as Fig. 3 A, shown in the 3B, the tape measure of the improved tape measure braking mechanism of tool the utility model, the tape strip 13 that comprises housing 11 is imported and exported 111A, brake button 12, tape strip 13, elements such as spring band 14 and rolling wheel 15, housing 11 can be by a left side, right two halves housing combines in the mode of screw interlocking, one housing centre can be provided with a spring band stationary shaft 21, reel with tape strip 13 in spring band 14 outsides, brake button 12 can be pushed in a chute 16, so that its pressure side 121, bottom can be pressed onto tape strip 13 or leave tape strip 13, cause tape measure brake or the state that do not brake, the improved tape measure braking mechanism of the utility model comprises: brake button 12 and be arranged at housing 11 inner faces and import and export the buffer body 2 that one of bottom 111A can clamp tape strip 13 with the pressure side of 12 pairs of tape strip 13 end faces of brake button near tape strip; Buffer body 2 is softer and the rubber-like material is made with rubber etc., buffer body 2 can be with housing 11 one-body molded or adhere to be fixed in housing 11 above; The position of buffer body 2 is when brake button 12 when pushing away downwards, and clamp tape strip 13 jointly the pressure side, bottom 121 that can make brake button 12 buffer body 2 therewith.
As shown in Figure 3A, be before the utility model does not move, braking is positioned at chute 16 tops of housing 11 by part 12, and the pressure side 121 of its bottom does not contact with tape measure 13, and tape strip 13 can freely be pulled out; When tape strip 13 is moved the location to and when needing fixedly, shown in Fig. 3 B, the button that will brake pushes away for 12 times, after the brake button moved down, the pressure side 121 of its bottom was the end face of ejection tape strip 13, and together clamps tape strip 13 with buffer body 2, because buffer body 2 is formed with flexible materials of summary tool such as rubber, its friction force to tape strip 13 greatly increases than housing, therefore, promptly can be effectively fixing tape strip 13.
Shown in Fig. 3 A, when brake button 12 upwards pushes away, tape strip 13 is furled, the buffer body of being located on housing 11 inner faces 2 is subjected to the effect of spring band 3 and during rollback at tape strip 13, promptly with tape strip 13 frictions, therefore tape strip 13 rollback speed can be slowed down, and the user can reduce and is given a shock and injures.
