Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 4, the self-locking structure of the tape measure comprises a main housing 1, and specifically, the main housing 1 comprises a left housing 10 and a right housing 11 which are spliced left and right. A reel 2 and a tape 3 arranged in the main casing 1, wherein at least part of the tape 3 is wound on the reel 2 and has a tape end capable of extending out of the main casing 1; the main casing body 1 is interior to lean on lower extreme position to rotate and is provided with damping piece 4, damping piece 4 includes pivot seat 40, the damping portion 42 that sets up at the pivot seat 40 one end at the press button 41 that sets up and set up at the pivot seat 40 other end, stretch out in the perforation 100 that the press button 41 set up from the main casing body 1 lower extreme the below of damping portion 42 is provided with the spring 6 of exerting thrust to it, damping portion 42 with spool 2 supports the pressure.

Thrust is applied to the damping piece 4 through the spring 6, so that the damping piece 4 is pressed against the reel 2, and the tape 3 is locked at the pull-out position; when the tape 3 is pulled out, the reel 2 overcomes the resistance of the damping piece 4 by applying a pulling force to one end of the tape 3, and the tape 3 is pulled out. Specifically, the damping portion 42 includes a main body seat 42b and a damping piece 42a embedded in the main body seat 42b, and since the damping portion 42 and the reel 2 are worn relatively, the damping portion 42 is configured to be a structure in which the damping piece 42a is matched with the main body seat 42b, and when the damping piece 42a is worn, the damping piece 42a can be replaced conveniently without scrapping the whole damping piece 4.

A first spring seat 101 is formed at the lower end of the main body seat 42b, a second spring seat 102 is disposed in the main housing 1 at a position opposite to the first spring seat 101, and the spring 6 is disposed between the first spring seat 101 and the second spring seat 102. By disposing the spring 6 between the first spring seat 101 and the second spring seat 102, the problem that the spring 6 is sprung or buckled can be effectively avoided.

A stop piece 5 is arranged above the pressing button 41 in the main shell 1, the upper end surface of the pressing button 41 is provided with an inclined surface, referring to fig. 1, the left end surface of the inclined surface is higher than the right end surface, when the inclined surface abuts against the stop piece 5, the front end part of the upper end surface of the pressing button 41 is pressed against the tape 3, at the moment, the damping piece 4 is separated from the reel 2, and the reel is unlocked; and because the front end part of the upper end surface of the pressing button 41 is pressed against the tape 3, equivalently, in the tape retraction process after the reel is unlocked, a certain damping is provided by the front end of the pressing button 41 to control the tape retraction speed; this avoids the problem of possible user damage when the tape is retracted too quickly.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The foregoing embodiments and description of the invention have been provided in the present application for the purpose of illustrating the principles of the invention and is subject to various changes and modifications without departing from the spirit and scope of the invention. All such variations and modifications are intended to be within the scope of the claimed invention.
