Description

Technical Field

[0001] The embodiments of this utility model belong to the field of measurement technology, and more specifically, relate to a multifunctional measuring tool ruler. Background Technology

[0002] The current tool used in the crew workshop to open the driver's cab door has a limited function; it can only be used temporarily to open the driver's cab partition door when the key is broken. A more versatile tool is needed that is easy for the onboard mechanic to carry and is simple and practical.

[0003] To further improve the efficiency of onboard mechanics in handling malfunctions and to address emergency situations encountered by onboard mechanics during their shifts, such as key failure preventing the driver's cab partition door from opening, partial dimensional measurements, pantograph valve pressure adjustment, and seat repairs.

[0004] Furthermore, in daily production, life, and various work scenarios, workers often need to use multiple tools to meet different measurement and operational needs. For example, during equipment installation and debugging, it is necessary to measure the dimensions of components and operate fasteners such as bolts; in manual production, length measurement and angle calibration are also required simultaneously. Traditional measuring tools, such as ordinary rulers and set squares, usually only have a single function of measuring length or angle and cannot meet the needs of operation. Workers often need to carry multiple tools with different functions, which not only increases the burden of carrying them but also makes it easy to forget tools, thus affecting the smooth progress of work. For example, when performing simple equipment maintenance, it may be necessary to use a ruler to measure the distance between components and a wrench to tighten screws; an ordinary ruler obviously cannot complete the screw-tightening operation. Even some so-called multi-functional tools have low functional integration, the switching between different functions is not convenient, and the combination of functions lacks rationality. For example, some multi-functional tools simply combine some infrequently used functions, ignoring the functions that are really needed in actual operation, which greatly reduces the efficiency of the tool in actual application.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Please refer to Figure 1 A multi-functional measuring tool ruler, comprising a right-angle ruler body 1 and a wrench head 3 fixedly connected to the right-angle ruler body 1; Please refer to Figure 2 The right-angle ruler 1 consists of two parts: a first rectangular ruler 11 and a second rectangular ruler 12. The first rectangular ruler 11 and the second rectangular ruler 12 are fixedly connected or hinged at a right angle. The gap in the driver's cab partition door is only about 1mm, so the thickness of the right-angle ruler 1 is also designed to be 1mm. This is to facilitate the measurement of wheel tread abrasion length, etc.

[0023] To improve safety, the outer corner of the right-angle ruler 1 is polished to form a smooth arc; at the same time, anti-slip grooves 8 are provided on the inner side of the first rectangular ruler 11 to enhance stability when holding it.

[0024] As a preferred solution, the outer side of the rectangular ruler 11 features an ergonomic curved surface that conforms to the curvature of the palm and is covered with a soft rubber material such as TPR anti-slip rubber, replacing the existing single anti-slip groove 8. This design not only reduces user fatigue during prolonged holding but also further enhances the anti-slip effect when hands are wet.

[0025] Please refer to Figure 3On the outer side of the second rectangular ruler, there is a protruding measuring protrusion 2, which is a wheel set abrasion measuring protrusion (2). The wheel set abrasion measuring protrusion (2) protrudes outward by 2mm. During measurement, the wheel set abrasion measuring protrusion is pressed against the abrasion of the wheel set. If it exceeds 2mm, it means that the abrasion range is exceeded. In addition, a threaded screw hole 6 is opened on the side surface of one end of the second rectangular ruler. Correspondingly, the screwdriver 5 is also provided with matching threads. By screwing the screwdriver 5 into the screw hole 6 of the second rectangular ruler, the two can be fixedly connected. Preferably, the screwdriver 5 can also be replaced with a utility knife or a marker pen to meet the needs of different scenarios. Furthermore, the threaded connection between the screwdriver 5 and the ruler can be upgraded to a quick-release buckle structure, such as a press-type lock with a positioning groove. In this way, when changing tool heads such as marker pens, there is no need to rotate or twist. The disassembly and assembly can be completed in just a few seconds, which greatly reduces the time spent on operation.

[0026] Please refer to Figure 4 The right-angle ruler body 1 is also equipped with a folding device 7, which allows the right-angle ruler body 1 to be rotated and folded, transforming it into a strip wrench and increasing the working distance.

[0027] Specifically, the first rectangular ruler body 11 and the second rectangular ruler body 12 are directly hinged together by the folding device 7. The folding device 7 includes a disc-shaped structure 711 with a hollowed-out side and a positioning bolt 721 set in the middle of the disc-shaped structure. The ends of the first rectangular ruler body 11 and the second rectangular ruler body 12 are inserted into the hollowed-out side of the disc-shaped structure. The ends of the first rectangular ruler body 11 and the second rectangular ruler body 12 are each opened with a circular hole. The positioning bolt 721 is inserted into the circular hole so that the circular holes formed by the first rectangular ruler body 11 and the second rectangular ruler body 12 overlap to form a hinged structure. The lower end of the positioning bolt 721 is also equipped with a fastening bolt 722. When the first rectangular ruler body 11 and the second rectangular ruler body 12 are rotated to a suitable angle, the fastening bolt 722 is tightened to fix the first rectangular ruler body 11 and the second rectangular ruler body 12.

[0028] The side cutout of the disc-shaped structure 711 is also provided with a stop block 712. The stop block 712 is used to limit the rotation angle of the first rectangular ruler 11 and the second rectangular ruler 12. When the first rectangular ruler 11 and the second rectangular ruler 12 are in contact with the stop block 712, the first rectangular ruler 11 and the second rectangular ruler 12 are directly perpendicular to each other.

[0029] Please refer to Figure 5The wrench head 3 is thicker than the right-angle ruler body 1. A transition slope 4 is provided at the fixed connection between the right-angle ruler body 1 and the wrench head 3. At the same time, the wrench head 3 is bent inward as a whole. Preferably, the wrench head 3 is magnetic, which can more easily attract bolts and other parts. In addition, the wrench head 3 can be replaced with an adjustable wrench head to further improve the tool's adaptability. In terms of specific selection, the wrench head 3 can be an M6 open-end wrench or an internal hex wrench head, which can be used for seat repair, disassembly of the air conditioner evaporator filter cover of the Fuxing bullet train, and adjustment of the pantograph valve plate pressure, etc., with multiple functions.

[0030] The scale lines on the right-angle ruler body 1 are flexibly set; they can be set on the upper or lower surface, or on the outer edges of both the upper and lower surfaces simultaneously. Furthermore, all scale lines are directly engraved on the surface of the right-angle ruler body 1.

[0031] As a preferred option, the graduation lines are made using laser engraving. After engraving, ceramic glaze is filled in, followed by high-temperature curing to form a dense, corrosion-resistant layer. This design effectively prevents the graduations from becoming blurred due to chemical corrosion, ensuring clear readability.

[0032] Please refer to Figure 6 In some preferred embodiments, a small bubble level is also embedded in the surface of the first rectangular ruler, which allows the tool to quickly determine whether the surface is level when performing installation, calibration and other tasks, making it more comprehensive in function.

[0033] This multi-functional measuring tool ruler is made entirely of alloy stainless steel with a powder-coated surface. This material selection and surface treatment give it excellent resistance to chemical corrosion, allowing it to better adapt to different acid and alkaline conditions and extending its service life.
