Abstract
The utility model discloses a flexible rule buffer mechanism, which comprises a rotating shaft which is movably connected to the inside of a shell. A flexible rule is fixed on the rotating shaft, a rotating piece is arranged on the rotating shaft, and a plurality of retaining blocks are fixed in a plurality of retaining block grooves arranged on the rotating piece and can slide along the retaining block groove. The flexible rule buffer mechanism can enable the flexible rule to be buffered when use is completed and flexible rule returns to the shell, so that users can be free of injury caused by too fast speed.
Description
Technical field
The utility model relates to a kind of tape measure buffer gear.
Background technology
After the tape measure of present stage was used to complete, when tape measure was returned to shell, speed can be very fast, because tape measure is extremely thin, holds very much incised wound user in evening.
The utility model content
In order to solve the problem that above-mentioned prior art exists, the purpose of the utility model is to propose a kind of tape measure buffer gear, and it can effectively solve the problems referred to above that prior art exists.
For realizing above-mentioned purpose, the utility model can solve through following technical scheme:
A kind of tape measure buffer gear, it comprises a rotating shaft that is movably connected in the shell, a fixing tape measure in this rotating shaft, said rotating shaft is provided with a revolving part, and some blocks are fixed in some block grooves that said revolving part is provided with and can slide along it.
As the further technical characterictic of the utility model, said block is fixed on the said revolving part through spring.
As the further technical characterictic of the utility model, the circumference place is provided with some convexities on the said block, and said enclosure and said block coupling place are provided with some convexities.
As the further technical characterictic of the utility model: a stationary shaft one end is fixed on the said shell and its fixing said rotating shaft.
Because adopt above technical scheme, a kind of tape measure buffer gear of the utility model in the time of can after tape measure is used to complete, returning in the shell, cushions it, prevent to hurt the user because of excessive velocities.
Description of drawings
Fig. 1 is the structure exploded perspective view of the utility model.
Fig. 2 is the structural representation of the utility model.
Among the figure: 1, cap; 2, revolving part; 3, block; 4, spring; 5, rotating shaft; 6, tape measure; 7, shell.
Embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the utility model:
Like Fig. 1 and shown in Figure 2, a kind of tape measure buffer gear, it comprises a rotating shaft 5 that is movably connected in the shell 7; Rotating shaft 5 can be rotated, and a fixing tape measure 6 in this rotating shaft 5 is fixedly connected a revolving part 2 in the rotating shaft 5; This revolving part 2 is through the fixing some blocks 3 of its some block grooves that are provided with; Block 3 can slide in the block groove, and the circumference place is provided with some convexities on the block 3, and shell 7 inside are provided with some convexities with block 3 coupling places.Block 3 is fixed on the revolving part 2 through spring 4.Block 3 can be for a plurality of, and in the present embodiment, block 3 is made as 2, symmetric offset spread, and two blocks 3 are fixed together through spring 4, and are fixed in the block groove.One stationary shaft, one end is fixed on the shell 7 and its fixed rotating shaft 5, and rotating shaft 5 can be rotated around it.
During use, after tape measure 6 is used to complete, press backspace key, tape measure 6 will return in the shell 2 fast; Because tape measure 6 is fixed in the rotating shaft 5, can drives the rotation of rotating shaft 5 when tape measure 6 is return, thereby drive the rotation of revolving part 2 and produce a centrifugal force, under action of centrifugal force; Block 3 outwards skids off with shell 2 in the block groove of revolving part 2 and contacts, because block 3 and shell 7 are provided with respective bump, can produce friction force in rotating shaft 5 rotating process; Thereby slowed down its rotation, because block 3 is fixed on the revolving part 2 through spring 4, it has only when rotating speed acquires a certain degree; The centrifugal force of generation is greater than the pulling force of spring 4, and block 3 just can outwards slide, when preventing because of speed too soon; Scratch the user, when speed slowed down, the centrifugal force of generation is stretchy spring 4 not; The centrifugal force that produce this moment is less than the pulling force of spring 4, and spring 4 is withdrawn into original position with block 3, and this moment, tape measure 6 can continue to slide.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
