Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right" etc. is based on the orientation or positional relationship shown in the drawings, and is only for It is convenient to describe the present invention and simplify the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and thus should not be construed as limiting the present invention.

[0039] a tape measure, such as figure 1 and figure 2 As shown, it includes ruler case 1, reel 3, ruler tape 2 and governor, reel 3, ruler tape 2 and governor are all installed in ruler case 1, and one end of ruler tape 2 protrudes from ruler case 1.

[0040] The ruler case 1 inc...

Abstract

The invention discloses a flexible rule which comprises a rule shell, a reel and a rule tape and also comprises a speed regulator. The speed regulator comprises a rotating wheel rotatably connected with the reel and a damping part providing rotating resistance for the rotating wheel, wherein the damping part is installed on the rule shell, a ratchet wheel and pawl mechanism for making the reel tounidirectionally drive the rotating wheel to rotate is arranged between the rotating wheel and the reel, and the reel drives the rotating wheel to rotate when the rule tape is withdrawn. When the ruletape is pulled out, the rule tape drives the reel to rotate, a ratchet wheel and pawl assembly is in an unengaged state at the moment, the rotating wheel is not driven to rotate under the interference of the damping part, and the rule tape can be normally used at the moment and is very easily pulled out. When the rule tape is withdrawn, the elastic force of a coil spring drives the reel to rotatereversely and drive the rule tape to be withdrawn, the reel drives the rotating wheel to rotate under the effect of the ratchet wheel and pawl mechanism at the moment, the rotation speed of the rotating wheel and the reel is reduced by the rotating wheel under the damping of the damping part, and accordingly the withdrawing speed of the rule tape is reduced.

Description

technical field [0001] The invention relates to the technical field of measuring tools, in particular to a tape measure. Background technique [0002] The authorized announcement number is CN203981048U, and the application date is April 3, 2014. The Chinese patent discloses a steel tape that can control the high and low speed retraction of the tape. Including gate, button, friction head and spring, there are three arc-shaped strip grooves horizontally on the gate, a spring is installed in front of the gate, and the spring is installed in the friction head; the upper clamping plate corresponding to the gate An arc-shaped bar-shaped boss corresponding to the arc-shaped bar-shaped groove is provided below. [0003] For the above-mentioned tape measure, when retracting the tape, if the retracting speed is fast, you can push the button forward slightly, so that the arc-shaped strip-shaped boss under the clamping plate on the ruler shell is stuck in the arc-shaped strip in the mi...
