[0001] The utility model belongs to the technical field of elevator inspection tools, and more specifically, particularly relates to a portable multifunctional inspection ruler. Background Art

[0002] During the installation, maintenance and inspection of elevators, various problems of measuring small dimensions such as gaps, meshing depths, and wire rope diameters will be encountered. Tools such as steel rulers, tape measures, vernier calipers, and feeler gauges are required to measure them to determine whether they meet the requirements of the inspection regulations. Different measuring tools are suitable for different types of dimensions. Gap dimensions such as elevator floor door gaps and escalator apron and step gaps are usually measured with feeler gauges. The meshing depth of elevator floor door locks is generally measured with a steel ruler. The wire rope diameter can be measured with a universal vernier caliper or a wide-jaw vernier caliper. The meshing distance between the escalator comb plate and the step is generally measured with a steel ruler and a feeler gauge.

[0003] The current elevator inspection ruler still has the following shortcomings:

[0004] When inspecting or maintaining the same elevator, operators usually need to switch between different measuring tools in the tool box and read the scale value, which is not convenient. In the dark environment of the elevator shaft, it is inconvenient to read the scale value, especially the reading efficiency of the vernier caliper is even lower. In addition, the current ruler is large in size and needs to be carried by hand, which brings inconvenience to the measurement personnel and is not conducive to improving work efficiency.

In the case of dim light in the elevator shaft, it is inconvenient to read the scale value, especially the reading efficiency of the vernier caliper is even lower, and the current ruler is large in size and needs to be carried by hand, which brings inconvenience to the measurement personnel and is not conducive to improving work efficiency.

[0006] The purpose and effect of the portable multifunctional inspection ruler of the utility model are achieved by the following specific technical means:

[0007] A portable multifunctional inspection ruler comprises: a fixing plate; the fixing plate adopts a rectangular plate structure; four groups of connecting blocks with rectangular block structures are fixedly arranged on the front side of the fixing plate in a rectangular array, and a through-type screw hole structure is opened on the top of the connecting block; two groups of bottom plates are fixedly arranged on the front sides of the two groups of connecting blocks at the bottom, and the screw hole structure is opened on the top of the bottom plate; two groups of upper plates are fixedly connected and arranged on the front sides of the two groups of connecting blocks at the top, and the top of the upper plate is opened with a through-type screw hole structure, and the top front side of the upper plate is opened with a length scale value.

[0008] Furthermore, a group of connecting bolts are rotatably arranged in the screw holes on the top of the two groups of upper plates through threaded cooperation, and the connecting bolts pass through the screw holes of the connecting blocks and are connected to the screw holes on the top of the bottom plate.

[0009] Furthermore, a connecting plate with an arc-shaped plate structure is fixedly provided on the rear side of the fixing plate, and a rectangular groove structure is opened on one side of the connecting plate.

[0010] Furthermore, a strap is fixedly connected to the outer side of the connecting plate; a cylindrical winding roller is rotatably arranged in a rectangular groove on one side of the connecting plate, and one end of the strap is fixedly connected to the winding roller; a worm gear is fixedly arranged on the top of the rotating shaft of the winding roller; a worm is rotatably arranged on the top of the connecting plate, and the worm is meshingly connected to the worm wheel.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the present application, the area where length measurement is required is detected through the two groups of length scales on the top of the upper plate, the width of the gap can be detected through the wedge-shaped structure area on one side of the bottom plate, and the stepped structure provided at the bottom of the upper plate forms a stepped width structure with the bottom plate, so that the diameter width of the wire rope can be directly engaged and detected to check whether the wire rope at the corresponding part meets the corresponding diameter, which greatly improves the practicality and functionality of the device, achieves the effect of multiple uses with one foot, and meets different usage needs.

[0013] Through the cooperation of the strap and the connecting plate, the device can be hung on the finger for easy carrying. When it needs to be hung on the wrist, the worm gear can be rotated by rotating the worm, thereby synchronously driving the winding roller to rotate and making the strap longer, so that the connecting plate and the strap can be put on the wrist, which makes it easier to carry the fixing plate. When in use, the inspector does not need to hold the device in his hand all the time, freeing up the inspector's hands and facilitating other work simultaneously, which is conducive to improving work efficiency.
