Description

Technical Field

[0001] This application relates to the field of measuring tape technology, and in particular to a fiber measuring tape with a buffer mechanism. Background Technology

[0002] Measuring tapes are measuring tools used in a variety of applications. Some measuring tapes include graduated, marked strips wound on a spool, and a retraction system for retracting the strips back onto the spool. In some measuring tape designs, the retraction system is driven by a coiled or helical spring, which is tensioned as the tape extends to store energy and releases that energy to rotate the spool, thus winding the strip back onto it. Common measuring tapes lack an automatic buffer mechanism; the tape retracts at high speeds only through friction with the rollers, resulting in insufficient stability, potential damage to the tape edges, and reduced lifespan. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] The problem to be solved by this application is to provide a fiber measuring tape with a buffer mechanism to overcome the defect in the prior art where the measuring tape does not have a buffer mechanism, which leads to easy wear and tear when the tape is retracted.

The fixing block is fixed within the housing. The two ends of the spring abut against the guide block and the fixing block, respectively. A tape turntable is also installed within the housing. The tape on the tape turntable passes through the tape opening between the guide block and the roller. The spring pushes the guide block toward the roller, thereby pressing against the tape to reduce friction and slowing down the tape retraction speed, thus protecting the tape.

[0008] In some embodiments, the end of the measuring tape is provided with a right-angle pull ring, the right-angle pull ring includes a connecting part and a plug part that are hinged to each other, the measuring tape is fixed on the connecting part, the plug part can be flipped along the connecting part, and the connecting part can pass through the opening of the measuring tape; the surface of the housing is provided with a positioning buckle, the plug part is provided with an opening, and after the plug part is folded over, the positioning buckle is locked on one side of the opening.

[0009] In some embodiments, the housing is provided with a limiting block below the guide block, the guide block is slidably disposed on the limiting block, the housing is provided with a positioning post, and the roller is rotatably mounted on the positioning post.

[0010] In some embodiments, the housing is further provided with a mounting base, the fixing block is fixed in the mounting base, a rotating wheel is mounted on the housing, the rotating wheel is connected to the tape turntable, a plurality of drive gears are rotatably mounted in the rotating wheel, the tape turntable is provided with an internal gear ring and an external gear ring, and the two sides of the drive gear mesh with the internal gear ring and the external gear ring respectively.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, the beneficial effects that can be achieved by the above-mentioned at least one technical solution adopted in the embodiments of this specification include at least the following: the guide block is pushed out to the side of the roller by the spring in the buffer mechanism, so that the tape contact the roller and the guide block when it is retracted, thereby reducing the friction force on the tape and reducing the retraction speed, which can avoid the tape from being damaged by friction during high-speed retraction and extend its service life.

The two sides of the drive gear 16 are respectively engaged with the internal gear ring 17 and the external gear ring 18. The rotating wheel 15 is connected to a handle 19 by flipping. After flipping the handle 19, the rotating wheel 15 can be driven to rotate by the handle 19. At this time, the drive gear 16 can be used to drive the tape turntable 7 to rotate for tape retraction by cooperating with the internal gear ring 17 and the external gear ring 18. The housing 1 is provided with a relief groove 20. When the handle 19 is stored, the end is placed in the relief groove 20.
