Problems solved by technology

[0002] In order to measure the performance of the workpiece (such as a tool) during the rotation process, the measurement equipment is generally started after the rotation speed of the workpiece reaches a preset value. However, it takes a certain reaction time to turn on the measurement equipment, so there is a defect that the measurement response speed is slow

Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intervening element at the same time. When an element is referred to as being "disposed on" another element, it can be directly disposed on the other element or intervening elements may also be present.

[0017] Unless otherwise defined, all technical and scientific terms used here...

Abstract

The invention provides a power switch and a measuring device with the same. The power switch comprises a rotating body, a switch assembly and two wiring bodies; the rotating body can be driven to rotate by taking own rotating shaft as the center, the switch assembly is contained in the rotating body and deviates from the rotating shaft, and the switch assembly can rotate together with the rotatingbody and enable the two wiring bodies to be electrically connected after the rotating speed of the rotating body exceeds a preset value; the switch assembly comprises a first elastic piece, a slidingblock and a second elastic piece which are sequentially arranged along the radial direction of the rotating body, and the sliding block can slide along the radial direction of the rotating body; thefirst elastic piece is located on one side of the sliding block close to the rotating shaft, one end of the first elastic piece is connected with the sliding block and the other end is connected witha wiring body; and one end of the second elastic piece is connected with the sliding block, and the other end of the second elastic piece is in contact with the remaining wiring body after the rotating speed of the rotating body exceeds the preset value. According to the power switch, the power supply can be automatically switched on after the rotating speed of the rotating body exceeds the presetvalue, and the response speed is high.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to a power switch and a measuring device with the power switch. Background technique [0002] In order to measure the performance of the workpiece (such as a tool) during the rotation process, the measurement equipment is generally started after the rotation speed of the workpiece reaches a preset value. However, it takes a certain reaction time to turn on the measurement equipment, so there is a defect that the measurement response speed is slow . Contents of the invention [0003] The object of the present invention is to provide a power switch capable of automatically turning on the power after the rotation speed of the rotating body exceeds a preset value and a measuring device with the power switch. [0004] In order to achieve the above object, the present invention provides a power switch, which includes a rotating body, a switch assembly and two wiring bodies, the rotati...
