[0001] The utility model belongs to the technical field of elevator inspection and testing equipment, and particularly relates to a gap measuring device for elevator inspection and testing. Background Art
[0002] There are mainly three purposes for gap measurement in elevator inspection and testing. One is to ensure safe operation, prevent people from being trapped or injured, and at the same time ensure the normal operation of the elevator mechanical system and reduce the probability of failures. The second is to comply with regulations and standards, abide by the requirements of laws and regulations, meet industry standard specifications, and avoid being punished for violations. The third is to improve elevator performance, optimize running smoothness, enhance reliability, improve passenger comfort, extend the service life of the elevator and reduce maintenance costs.
[0003] Since the measurement of elevator door leaf gaps and the dimensions of landing and car door sills are important items in the elevator inspection and testing process, there are a large number of measurement data, and some measurement positions are gaps with right-angled sides. Most of the existing gap measuring devices for elevator inspection and testing directly measure through a straight ruler or in a way of two-way unfolding during use, resulting in problems such as the deviation of the straight ruler direction or the inability to unfold in the process of data acquisition, leading to relatively low measurement efficiency. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is that the existing gap measuring device for elevator inspection and testing may have problems such as the deviation of the straight ruler direction or the inability to unfold other measuring tools during use, resulting in relatively low measurement efficiency.

[0009] Through the above technical solution, it is prevented that the two ends of the placement plate collide with the positioning plate when the placement plate rotates and lies horizontally, and the two ends of the placement plate are located on both sides of the positioning frame, increasing the lateral contact area between the bottom of the positioning frame and the ground, and making the placement more stable.
[0010] Preferably, the top of the connecting rod is provided with a thread below the limiting piece and is connected with a nut in a threaded manner.
[0011] Through the above technical solution, during the process of placing the positioning frame, the connecting rod rises as the movable plate and the placement plate rise, and the nut is used to prevent it from resetting.
[0012] Preferably, distance scales are provided above the measuring ruler, and the starting scale of the distance scales is located at the end of the measuring ruler far from the grip.
[0013] Preferably, an extension plate is slidably connected to the end of the measuring ruler far from the grip.

[0018] The advantages of the present utility model compared with the prior art are as follows:
[0019] This measuring device positions one side edge of the gap to be measured by a positioning plate on one side of the bottom to prevent skew during the measurement process. At the same time, the screw is driven by the rotation of the adjustment sleeve, and the measuring ruler is extended outward along the limit slot, so that the outer end of the measuring ruler is aligned with the plane or position of the desired measurement location, so that the reading is taken according to the position of the distance scale and the positioning mark on the measuring ruler. The lighting is turned on for reading when the environment is dark, so that the purpose of skewness will not occur during the measurement process and one-way accurate measurement is achieved.
