Device capable of measuring opening angle of vehicle door simply and conveniently

Abstract

The invention relates to a device capable of measuring the opening angle of a vehicle door simply and conveniently, and belongs to the technical field of angle measurement. The device comprises two vacuum sucking disc, two plumbs, a dial pedestal, and a pointer. Each vacuum sucking disc comprises a sucking disc and a sucking disc hoop. Each plumb comprises a plumb line and a plumb block, and the front end of the plumb line is tied on the corresponding sucking disc hoop. The dial pedestal comprises a positioning straight rule and an angle disc, and an end part of the positioning straight rule is provided with a rotating shaft. An end part of the pointer is provided with a rotating shaft groove, and the pointer is disposed on the rotating shaft of the positioning straight rule, thereby enabling the pointer to be able to rotate around the rotating shaft on the positioning straight rule. The device can save a calculation process, reduces the measurement error, and can achieve the direct reading of the opening angle of the vehicle door.

Description

technical field [0001] The invention relates to the technical field of angle detection, and more specifically, the invention relates to a device that can simply measure the opening angle of a car door. Background technique [0002] In the existing technology, when measuring the opening angle of the car door, it is necessary to measure the displacement of a certain mark point after opening the car door, and manually calculate the opening angle through the trigonometric function relationship, which is not only time-consuming, but also when measuring the mark point displacement, the error measured by different people is different , so the final calculation error is large. CN202692974U discloses a vehicle door maximum opening angle detection device consisting of a base, a support rod, a horizontal plate, a rotating block, a connecting rod, a suction cup and an angle sensor. To measure the maximum opening angle of the car door, the detection device needs to be equipped with a ho...
