Description

Technical Field

[0001] This utility model relates to the field of highway inspection technology, specifically a multi-functional ruler for highway inspection. Background Technology

[0002] As the core infrastructure of modern transportation networks, highways bear crucial functions such as logistics and commuting. Their structural stability directly affects driving safety and service life. For example, problems like road surface cracks, excessive slope, or worn road markings can lead to traffic accidents or significantly increased maintenance costs. Therefore, highway inspection is an essential part of routine maintenance and quality control. Precise measurements are needed to assess parameters such as road surface smoothness, crack width, and slope to ensure compliance with national standards. Currently, commonly used highway inspection tools include distance measuring wheels, measuring rulers, and feeler gauges. Distance measuring wheels are used for long-distance measurements, accumulating distance data through wheel rolling, suitable for large-scale inspections. Measuring rulers, as local precision measuring tools, can be unfolded to check road surface smoothness and slope. Feeler gauges are used to measure small gaps. Existing distance measuring wheels, folding measuring rulers, and feeler gauges are usually independent devices, requiring separate carrying and switching, leading to reduced on-site work efficiency, inconvenient storage of accessories, and easy loss of parts. This design fails to achieve "one tool for two purposes," limiting versatility, especially increasing the carrying burden in remote areas. Utility Model Content

[0003] The purpose of this invention is to provide a multi-functional ruler for highway inspection, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution;

[0005] A multi-functional ruler for highway inspection includes a distance measuring wheel and a folding measuring ruler. The folding measuring ruler includes a first ruler body and a second ruler body, which are connected by a hinge. The distance measuring wheel is fixedly mounted with a cover, which has a slot. The other end of the first ruler body is inserted into the slot, and the first ruler body and the cover are fixed together by a threaded knob. A level is mounted on the upper part of both the first and second ruler bodies. A first magnetic attractor and a second magnetic attractor are respectively mounted on the side of the first and second ruler bodies. A groove is formed on the side of the second ruler body, and a spring shaft is fixedly mounted in the groove. A spring and a slider are movably mounted on the spring shaft, and the slider abuts against the spring. A pin is mounted on the slider facing the first ruler body, and the pin is engaged with a hole on the end face of the first ruler body.

[0006] As a further embodiment of this utility model, hand grip grooves are provided on both the first and second rulers.

[0007] As a further improvement of this utility model: the end of the first ruler body that is inserted into the slot is provided with a threaded hole that is compatible with the threaded knob.

[0008] As a further improvement of this utility model: both the first ruler body and the second ruler body have feeler gauge grooves on their sides, and feeler gauges are installed in the feeler gauge grooves.

[0009] As a further improvement of this utility model, length scale lines are provided on the sides of the first and second rulers.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model achieves dual-purpose functionality through a modular connection design between the measuring wheel and the folding measuring ruler. When unfolded, the folding ruler can be used as an independent measuring tool, in conjunction with a level to detect the flatness / inclination of the road surface. When folded, the ruler body is inserted into the slot of the measuring wheel cover, directly converting into a measuring wheel handle, eliminating the need to carry an extra handle. This facilitates wheel-type distance measurement of the road surface, thereby reducing tool switching time and improving on-site work efficiency. It is especially suitable for scenarios where long-distance distance measurement and local accuracy detection are carried out alternately (such as measuring the length immediately after locating road cracks).

[0012] 2. This utility model utilizes the internal space after the folding ruler is closed to integrate a feeler gauge storage function, solving the pain points of feeler gauges being easily lost and difficult to store. The overall size of the tool is reduced, making it particularly suitable for lightweight carrying needs during field inspections. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 In this embodiment of the invention, a multifunctional ruler for highway inspection includes a measuring wheel 1 and a folding measuring ruler 2. The folding measuring ruler 2 includes a first ruler body 5 and a second ruler body 6, with a hinge 7 between the first ruler body 5 and the second ruler body 6, and the first ruler body 5 and the second ruler body 6 are hinged together by the hinge 7. The measuring wheel 1 includes a wheel body and a counter, which is an existing mature device. A cover 21 is fixedly installed on the measuring wheel 1, and a slot 3 is provided on the cover 21. The other end of the first ruler body 5 is inserted into the slot 3, and the first ruler body 5 and the cover 21 are connected by threads. The knob 4 is fixed. A level 10 is installed on the upper part of the first ruler 5 and the second ruler 6. A first magnetic 8 and a second magnetic 9 are installed on the side of the first ruler 5 and the second ruler 6, respectively. A groove 15 is opened on the side of the second ruler 6. A spring shaft 16 is fixedly installed in the groove 15. A spring 17 and a slider 18 are movably installed on the spring shaft 16. The slider 18 and the spring 17 abut against each other. A pin 19 is installed on the slider 18 facing the first ruler 5. The pin 19 is inserted into the insertion hole 20 opened on the end face of the first ruler 5.

[0019] Both the first ruler 5 and the second ruler 6 have hand grip grooves 11. When unfolded for measurement, fingers naturally embed into the grooves to avoid slipping, especially in rainy weather or when working with gloves on. When folded and stored, the grooves form a handle structure, making it more stable to hold with one hand and reducing fatigue during long-term operation. It is especially suitable for scenarios where the grip posture needs to be frequently adjusted, such as steep slopes or uneven roads.

[0020] The first ruler 5 has a threaded hole 12 on one end that is inserted into the slot 3, which is adapted to the threaded knob 4. The depth of the threaded hole 12 is standardized to ensure that the first ruler 5 can be fixed after the threaded knob 4 is screwed in.

[0021] Both the first ruler body 5 and the second ruler body 6 have feeler gauge grooves 13 on their sides, and feeler gauges 14 are installed in the feeler gauge grooves 13. This design solves the problem that feeler gauges 14 are easy to be lost, and reduces the loss rate of accessories in field operations.

[0022] The first ruler body 5 and the second ruler body 6 are provided with length scale lines 22. The length scale lines 22 are provided so that the measuring ruler can be used as a ruler to measure the width of cracks / markings when it is unfolded, thus enriching the function of the measuring ruler.

[0023] The working principle of this utility model is:

[0024] First, unfold the folding measuring ruler 2 via hinge 7. During unfolding, press the slider 18 with your finger and squeeze the spring 17 to retract the pin 19 into the second ruler body 6. When the first ruler body 5 and the second ruler body 6 are fully unfolded and form a straight line, release the slider 18. The pin 19 will automatically insert into the socket 20, achieving a stable connection between the first ruler body 5 and the second ruler body 6. At this time, the level 10 can be used to initially detect the road surface slope. Simultaneously, the feeler gauge 14 can be taken out from the feeler gauge slot 13 and used in conjunction with the folding measuring ruler 2 to measure the road surface levelness and to measure crack gaps. If distance measurement is required, then... Insert the first ruler 5 into the slot 3 of the cover 21 and fix it with the threaded knob 4 to convert it into a distance measuring wheel handle. Then, during the actual measurement stage, the user pushes the distance measuring wheel 1 to roll to record long-distance data. At the same time, the folding ruler can be used alone for local accuracy testing, such as measuring the width of cracks with the length scale line 22 when unfolded, or checking the flatness with the level 10. The feeler gauge 14 is used to supplement the measurement of small gaps. Finally, after the operation is completed, the user folds the ruler, the magnetic attachment locks it, and the feeler gauge 14 is pressed back into the feeler gauge slot 13. The whole thing is compactly stored, the tool returns to its initial state, effectively preventing loss and reducing volume.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
