Abstract

The utility model discloses a novel brake tape band self-locking tapeline. An obverse tape shell and a reverse tape shell are connected, an obverse tape shell upper slide is connected with a button shifting fork, an obverse tape shell lower slide is connected with a tape band, an obverse tape shell blocking baffle is connected with the obverse tape shell upper slide, an elastic piece is connected with the button shifting fork, a button shifting fork clamping hook is disposed on the button shifting fork, a round brake tape roller is connected with a round brake tape sleeve, the round brake tape roller is connected with the button shifting fork clamping hook, a tape core is connected with the tape band, and the tape band is disposed inside the device. According to the novel brake tape band self-locking tapeline, the round brake tape roller and the round brake tape sleeve are connected together, and the round brake tape sleeve drives the tape band to contract through a tape spring so as to enable the round brake tape roller to rotate in a slide of the button shifting fork and enable original one-point wear of the round brake tape sleeve to be changed into circumferential wear, thus improving the service life of the tapeline and saving raw materials.

Description

A kind of novel chi band self-locking tape measure of stopping

Technical field

The utility model relates to the technical field of automatic tape measure, especially a kind of novel chi band self-locking tape measure of stopping.

Background technology

Tape measure is a kind of important survey instrument, but automatic tape measure is in the market very short serviceable life, easily wearing and tearing, there will be tape band is stuck, button comes off phenomenon for making up the deficiencies in the prior art while even using, the utility model aims to provide the novel chi band self-locking tape measure of stopping of one.

Utility model content

For the problems referred to above, the utility model aims to provide a kind of novel chi band self-locking tape measure of stopping.

For realizing this technical purpose, scheme of the present utility model is: a kind of novel chi band self-locking tape measure of stopping, comprise positive chi shell, positive chi shell sliding way, positive chi shell glide path, positive chi shell blocks card shelves, shell fragment, button, button shift fork, button shift fork snap fit, the chi round roller of stopping, the chi of stopping circle cover, chi core, chi band, anti-chi shell, described positive chi shell is connected with anti-chi shell, described positive chi shell sliding way is connected with button shift fork, described positive chi shell glide path is connected with chi band, described positive chi shell blocks card shelves and is connected with positive chi shell sliding way, described shell fragment is connected with button shift fork, described button shift fork snap fit is positioned on button shift fork, the described chi round roller of stopping is connected with the chi circle cover of stopping, the described chi round roller of stopping is connected with button shift fork snap fit, described chi core is connected with chi band, it is inner that described chi band is positioned at this device.

As preferably, described chi band is realized and is stretched or shrink by button.

As preferably, described chi band blocks chi core.

As preferably, described in stop chi round roller, the chi of stopping circle cover be connected with chi shell sliding way just.

The utility model was broken in the past the traditional concept of tape measure automatically, small and exquisite flexible, simple in structure; Adopt the round roller formula chi structure of stopping, the chi round roller of stopping links together with the chi circle cover of stopping, this chi circle cover of stopping drives chi band contractile motion by chi spring, this chi round roller of stopping is rotated in the slideway of button shift fork, the chi circle cover that makes to stop has become circumference wearing and tearing by original some wearing and tearing, not only improve the serviceable life of tape measure, and saved starting material; The utility model is in order to dwindle physical dimension and the space of tape measure, on chi shell, be designed with slideway with obstruction mechanism, when stop chi round roller and the chi circle of stopping are enclosed within lifting, positive and negative chi shell sliding way forces stop chi round roller and the chi circle of stopping to be enclosed within reasonable interval stop chi band or release, this chi round roller of stopping is at the inner fast lifting of slideway, can not depart from again positive and negative chi shell, the slideway structure of button shift fork is simple and practical; The button of the chi structure of originally stopping has adopted the design of button shifting fork structure, and the shift fork of button is with slideway structure; In the termination of button shift fork slideway, be provided with the button shift fork snap fit that the chi round roller that prevents from stopping comes off.
