Description

Technical Field

[0001] The utility model belongs to the technical field of gap detection, in particular to a gap detection gap ruler. Background Art

[0002] The size detection of elevator car door gaps, escalator apron and step gaps, sill gaps, etc. is an important part of elevator installation, maintenance and inspection. The gap size meets safety standards and can improve the safety of elevator operation.

[0003] The gauges commonly used to detect elevator gaps mainly include conical gap gauges, wedge-shaped vernier feeler gauges, thickness gauges, etc. Among them, the conical gap gauge with a measuring range of 1~15mm is more commonly used. Its tip is narrow and its tail is wide. Its tip is sharp, which poses a safety hazard. There is a certain length between its tip and tail. There is a problem that the conical gap gauge is inserted into the gap but its two sides have not yet contacted the sides of the gap to be measured, resulting in the inability to accurately measure the gap width and poor flexibility in use. Utility Model Content

The outer end of the slider extends out of the sliding groove, and the inner end of the slider is fixedly connected to the slide plate. By moving the slider by hand, the slider can be pushed to move in the sliding groove, and at the same time, the slide plate and the ruler body can be driven to move in the cavity, so that the right end of the ruler body can enter and exit the cavity, and one section of the ruler body can be selected and pushed out of the cavity by pushing the slider for measuring the gap width.

[0010] Furthermore, there are two partitions, which divide the interior of the box into three chambers; the conical gap ruler includes a first section of the ruler, a second section of the ruler and a third section of the ruler, the measuring range of the first section of the ruler is 1~5mm, the measuring range of the second section of the ruler is 5~10mm, the measuring range of the third section of the ruler is 10~15mm, and the measuring range of the conical gap ruler is 1~15mm.

External force needs to be applied to the slider by hand to move the slide plate in the chamber. When no external force is applied, the position of the conical gap ruler can be kept fixed. When the conical gap ruler is stored in the box body, the conical gap ruler can be prevented from slipping out. When the gap is detected, the conical gap ruler can be pulled out from the gap and the measurement result can be read, which is convenient for operation.
