Abstract
Description
Technical Field
[0001] The utility model relates to the field of measuring tooling, in particular to an auxiliary measuring tooling structure. Background Art
[0002] The door unlocking function is crucial for rail transit vehicles, directly impacting vehicle safety. The emergency unlocking device is a crucial component of the door unlocking mechanism. In an emergency, pulling the operating handle drives the wire rope to unlock the door, allowing passengers to safely open the door. If the wire rope is too loose, the force applied to the handle will be insufficient, preventing the door from opening. If the wire rope is too tight, the operating torque will be too high, preventing the handle from unlocking the door. Therefore, measuring the force applied to the operating handle is crucial for standardizing the design and assembly of emergency unlocking devices.
[0003] The existing auxiliary measuring tools for measuring the force of pulling the operating handle have the following shortcomings: (1) When hooking the operating handle for measurement, the hook-type auxiliary measuring tool will damage the surface of the operating handle, affecting the appearance; and the measurement point of force is far from the center, resulting in inaccurate measurement. (2) The machining cost of metal auxiliary measuring tools is high, and the surface of the operating handle will be worn and damaged during the measurement process. (3) The manufacturing of nylon auxiliary measuring tools requires a new mold, which has a long manufacturing cycle and a small amount of tooling, so the manufacturing cost is high.
[0004] Therefore, it is necessary to develop new auxiliary measurement tooling to reduce manufacturing costs and avoid damage to the operating handle. Utility Model Content

[0006] Technical solution: The utility model is an auxiliary measuring tool structure, which is characterized by comprising an auxiliary measuring tool and an operating handle; the auxiliary measuring tool is clamped at the upper end of the operating handle; and a safety installation gap is left between the auxiliary measuring tool and the operating handle.
[0007] Wherein, the auxiliary measurement tooling is a measurement tooling produced by 3D printing.
[0008] Wherein, a measuring tool mounting hole is provided on the upper portion of the groove of the auxiliary measuring tool.
[0009] Wherein, a hole for preventing the measuring tool from falling off is provided at the lower part of the groove of the auxiliary measuring tool.
[0010] Wherein, the measuring tool mounting hole of the auxiliary measuring tool is connected to the measuring tool anti-drop hole and corresponds to the operating handle.
[0011] Wherein, the operating handle is inserted into the measuring tool mounting hole and the measuring tool anti-drop hole of the auxiliary measuring tool groove.
[0012] Wherein, the operating handle is located on the door system of the rail transit vehicle.
[0013] Beneficial effects: Compared with the existing technology, the utility model has the following significant advantages: the utility model uses 3D printing technology to manufacture auxiliary measurement tooling, 3D printing technology has diversified raw material selection and model selection, and does not require operations such as mold opening, which can effectively shorten the manufacturing cycle, reduce manufacturing costs, increase service life, ensure measurement accuracy, and avoid damaging the surface of the operating handle. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 2 This is a schematic cross-sectional view of the utility model;
[0016] In the figure, 1 is the auxiliary measuring tool; 2 is the operating handle. DETAILED DESCRIPTION
[0017] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0018] The auxiliary measuring tool structure of the present invention comprises an auxiliary measuring tool 1 and an operating handle 2; the auxiliary measuring tool 1 is clamped on the upper end of the operating handle 2; and a safety gap for installation is left between the auxiliary measuring tool 1 and the operating handle 2.
[0019] The auxiliary measuring tool 1 of the present invention is a measuring tool produced by 3D printing. A measuring tool mounting hole is provided on the upper part of the groove of the auxiliary measuring tool 1. A measuring tool anti-drop hole is provided on the lower part of the groove of the auxiliary measuring tool 1. The measuring tool mounting hole of the auxiliary measuring tool 1 is connected to the measuring tool anti-drop hole and corresponds to the operating handle 2. The operating handle 2 is snapped into the measuring tool mounting hole and the measuring tool anti-drop hole of the groove of the auxiliary measuring tool 1. The operating handle 2 is located on the door system of a rail transit vehicle. The measuring tool mounting hole on the upper part of the groove of the auxiliary measuring tool 1 is used for snapping in the operating handle 2; the measuring tool anti-drop hole on the lower part of the groove of the auxiliary measuring tool 1 is used to prevent the operating handle 2 from falling off during the measurement process.
[0020] like Figure 1-2The auxiliary measuring jig 1 is manufactured using 3D printing technology. When measurement is required, the auxiliary measuring jig 1 is clamped onto the upper end of the operating handle 2. The measuring tool clamping hole provided on the auxiliary measuring jig 1 facilitates the insertion of the measuring tool. The combined design of the groove of the auxiliary measuring jig 1 and the anti-drop hole at its lower part prevents the operating handle 2 from falling off during the measurement process. The auxiliary measuring jig 1 manufactured using 3D printing technology has a reasonable structure and is made of suitable materials, so that the surface of the operating handle 2 will not be damaged during the measurement process. Since a safety gap is left between the auxiliary measuring jig 1 and the operating handle 2, the auxiliary measuring jig 1 will not damage the surface when it is clamped into the operating handle 2 for connection.
[0021] The utility model effectively solves the problems of long manufacturing cycle, high manufacturing cost, short service life, inaccurate measurement accuracy and damage to the surface of the operating handle 2 of the auxiliary measurement tooling. 3D printing technology has diversified raw material selection and model selection, and does not require operations such as mold opening, which effectively shortens the manufacturing cycle, reduces manufacturing cost, increases service life, ensures measurement accuracy, avoids damage to the surface of the operating handle 2, and effectively solves the problems existing in the current auxiliary measurement tooling.
