Gap measuring device and particularly elevator landing door gap measuring instrument

Abstract

The invention discloses a gap measuring device, and particularly provides an elevator landing door gap measuring instrument which comprises a first body, a second body, an elastic component and a tensile force component. A fixed measuring angle, distance measuring first scales and tensile force measuring second scales are arranged on the first body, and the fixed measuring angle corresponds to a start point of the first scales; the second body is slidably mounted on the first body, and a movable measuring angle is arranged on the second body, corresponds to the start point of the first scales when the movable measuring angle is in an initial state and corresponds to the certain first scale when the second body slides; the elastic component is connected with the second body; an end of the tensile force component is connected with the elastic component, and an indicating component is arranged on the tensile force component, corresponds to a start point of the second scales when the indicating component is in an initial state and corresponds to the certain second scale when the tensile force component moves. The elevator landing door gap measuring instrument has the advantages of reasonable structure, simplicity and convenience in operation, accuracy in measurement and the like.

Description

[0001] technical field [0002] The invention relates to a device for measuring the clearance of objects under the state of applying force, in particular to a measuring instrument for the clearance of elevator landing doors. [0003] Background technique [0004] For the measurement of the elevator door gap, the current detection method mainly adopts manual and visual inspection. This method is laborious and laborious. Especially for the elevator door, 150N manpower is applied to measure the gap value at the most unfavorable point, which is affected by human factors. Large, because it is carried out in the shaft, the working environment is poor, and the operation is difficult, which can easily lead to fatigue of the surveyors. Coupled with some other adverse factors, it is easy to cause inaccurate data measurement. [0005] Contents of the invention [0006] The present invention aims to solve at least one of the technical problems existing in the prior art. [0007] Fo...
