Description

Technical Field

[0001] This utility model relates to the field of road surface detection technology, specifically to a road surface evenness detector. Background Technology

[0002] In road construction, maintenance, and various site surface construction processes, road surface smoothness is a crucial indicator. It directly affects not only the comfort and safety of vehicle driving but also the service life of roads and sites. Current testing methods typically involve using a straightedge and feeler gauge. However, straightedges are generally 3m or even 4m long, taking up considerable space during transportation and storage, causing inconvenience for testing personnel. Furthermore, when testing road surface smoothness at night or in dimly lit environments, insufficient natural light makes it difficult for testing personnel to accurately identify unevenness. Moreover, nighttime testing usually requires large, bulky, and heavy lighting equipment, which is inconvenient to operate and increases testing costs. Utility Model Content

[0003] The purpose of this invention is to provide a road surface smoothness detector that can provide clear illumination at night, is easy to observe and operate, and has good portability and storage.

[0004] A road surface smoothness detector includes a detection ruler body and light strip assemblies. The detection ruler body includes two detection scales, which are rotatably connected by a connecting hinge. A spirit level is installed on each detection scale. Two sets of light strip assemblies are detachably installed on both sides of the detection ruler body.

[0005] In the above solution, the two measuring scales of the measuring ruler body are connected by a hinge. The folded measuring ruler occupies little space and is easy to store in a vehicle or toolbox, reducing the difficulty of transportation and storage. When conducting road surface smoothness testing, the operator can quickly and accurately determine whether the measuring ruler body is in a horizontal state by observing the position of the spirit level. The light strip assembly provides illumination at night, allowing the operator to clearly observe the gap between the measuring ruler and the road surface, quickly locate the unevenness of the road surface, and facilitate subsequent measurement with a feeler gauge. When the illumination is not needed, the light strip assembly can be removed, which reduces the overall weight, makes the testing operation easier, and does not increase the size of the measuring ruler body when stored.

[0006] Furthermore, the light strip assembly includes a light strip housing and an LED light strip, the LED light strip is installed inside the light strip housing, a power module is installed on the main body of the measuring ruler, and the power cord of the LED light strip is connected to the interface of the power module.

[0007] In the above scheme, the LED light strip is installed inside the light strip housing, which provides protection for the LED light strip and prevents it from being interfered with or damaged by the external environment. The power module is installed on the main body of the detection ruler to ensure the stability of the power module. The power module is powered by the battery. When testing at night, the power cord of the LED light strip can be inserted into the interface to turn on the LED. When disassembling the light strip assembly, the power cord can be unplugged from the interface.

[0008] Furthermore, at least one male buckle is connected to the outer shell of the light strip, and at least one female buckle is connected to the main body of the measuring ruler, with the male buckle and the female buckle being movably engaged.

[0009] In the above solution, the movable snap-fit ​​method of the male and female buckles is simple to operate. The tester only needs to align the male buckle on the outer shell of the light strip with the female buckle on the main body of the test ruler and insert it to complete the assembly of the light strip assembly. This can save assembly time and improve work efficiency. When the light strip assembly is no longer needed or the test ruler is stored after testing, the tester can easily separate the male buckle from the female buckle and remove the light strip assembly from the main body of the test ruler.

[0010] Furthermore, the female buckle is provided with a slot, and the male buckle is provided with a protruding structure, which slides and engages with the slot.

[0011] In the above solution, the male buckle can be gently slid along the direction of the slot to complete the engagement between the male buckle and the female buckle, ensuring that the light strip assembly maintains a stable connection throughout the entire testing process, providing continuous and reliable lighting for the testing work. No excessive force or additional tools are required when assembling the light strip assembly, making the operation convenient and quick. Moreover, the structure of the male and female buckles is simple, resulting in low production costs.

[0012] Furthermore, the connecting hinge includes a first rotating connecting block and a second rotating connecting block, which are connected to the detection measuring scale and are rotatably connected.

[0013] In the above scheme, the first rotating connecting block and the second rotating connecting block are rotatably connected and firmly connected to the measuring scale, which can ensure the stability of the measuring scale during unfolding and use. The connecting hinge allows the two measuring scales of the measuring scale body to rotate relative to each other. When the measuring scale is not in use, the two measuring scales can be folded up by rotating the connecting hinge, which greatly reduces the space occupied by the measuring scale as a whole.

[0014] Furthermore, the first rotating connecting block is provided with a rotating connecting part, the rotating connecting part is provided with at least one connecting groove, the second rotating connecting block is provided with a connecting protrusion, the connecting protrusion is embedded in the connecting groove, and a connecting shaft passes through the central axis of the rotating connecting part and the connecting protrusion.

[0015] In the above scheme, the connecting protrusion is embedded in the connecting groove, forming a tight mechanical connection. This tight fit can effectively prevent loosening or displacement between the two rotating connecting blocks during use, ensuring that the connection between the components of the measuring scale is stable and reliable during unfolding and folding. The connecting shaft passes through the central axis of the rotating connecting part and the connecting protrusion, providing a stable rotation axis for the two rotating connecting blocks.

[0016] Furthermore, each of the two measuring scales is movably connected to a connecting screw at one end near the connecting hinge, and a connecting piece is connected between the connecting screws.

[0017] In the above solution, the connecting piece is connected to the two measuring scales by connecting screws. When the measuring scales are unfolded, the connecting piece acts like a stable bridge, tightly connecting the two measuring scales together, which greatly enhances the overall stability of the measuring scale. When the measuring scales need to be unfolded, the inspectors can quickly install the connecting piece onto the measuring scales by connecting screws. After the inspection work is completed, the connecting piece can be easily removed, which facilitates the storage and carrying of the measuring scales.

[0018] Furthermore, the connecting piece is provided with an elongated oval hole and a connecting groove, one of the connecting screws is connected to the elongated oval hole, and the other connecting screw is connected to the connecting groove.

[0019] In the above scheme, one connecting screw first passes through the oblong hole to initially fix the connecting piece to one measuring scale, and the other connecting screw first fixes it to another measuring scale. When the two measuring scales are unfolded, the oblong hole allows the connecting piece to adjust its position within a certain range, so that the connecting slot of the connecting piece can be connected with the connecting screw. The inspector does not need to spend a lot of time to accurately align the hole, which reduces the operational difficulty and time cost in the installation process, thereby improving the efficiency of installation.

[0020] This utility model discloses a road surface evenness detector that provides clear illumination at night, facilitating observation and operation, while also offering excellent portability and storage. The two measuring scales of the main body of the detector are connected by a hinge, allowing for easy folding and storage in vehicles or toolboxes, reducing transportation and storage difficulties. During road surface evenness testing, operators can quickly and accurately determine whether the main body of the detector is level by observing the position of the spirit level. The light strip assembly provides illumination at night, enabling operators to clearly observe the gap between the detector and the road surface, quickly locating uneven areas and facilitating subsequent measurement with a feeler gauge. When illumination is not needed, the light strip assembly can be removed, reducing the overall weight and making the testing operation easier, without increasing the size of the main body of the detector during storage.

[0030] The road surface smoothness detector of this utility model will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0031] like Figure 1 and Figure 2As shown in a preferred embodiment, the road surface smoothness detector of this utility model includes a detection ruler body 1 and a light strip assembly 3. The detection ruler body 1 includes two detection scales 11, which are rotatably connected by a connecting hinge 2. A spirit level 12 is installed on the detection scale 11. Two sets of light strip assemblies 3 are detachably installed on both sides of the detection ruler body 1. The two detection scales 11 of the detection ruler body 1 are rotatably connected by the connecting hinge 2. The folded detection ruler occupies little space and is easy to store in a vehicle or toolbox, reducing the difficulty of transportation and storage. When conducting road surface smoothness testing, the operator can quickly and accurately determine whether the detection ruler body 1 is in a horizontal state by observing the position of the spirit level 12. The light strip assembly 3 provides illumination at night, enabling the operator to clearly observe the gap between the detection ruler and the road surface, quickly locate the unevenness of the road surface, and facilitate subsequent measurement with a feeler gauge. When the illumination is not needed, the light strip assembly 3 can be removed, which can reduce the overall weight, making the testing operation easier, and does not increase the size of the detection ruler body 1 when stored.

[0032] like Figure 2 and Figure 3 As shown, in some embodiments, the light strip assembly 3 includes a light strip housing 31 and an LED light strip 32. The LED light strip 32 is installed inside the light strip housing 31. A power module 8 is installed on the main body 1 of the measuring ruler, and the power cord of the LED light strip 32 is connected to the interface of the power module 8. The LED light strip 32 is installed inside the light strip housing 31, which provides protection for the LED light strip 32 and prevents it from being interfered with or damaged by the external environment. The power module 8 is installed on the main body 1 of the measuring ruler to ensure the stability of the power module 8. The power module 8 is powered by a battery. When testing at night, the power cord of the LED light strip 32 can be inserted into the interface to turn on the LED. When disassembling the light strip assembly 3, the power cord can be unplugged from the interface.

[0033] like Figures 2 to 5 As shown, in some embodiments, at least one male buckle 5 is connected to the upper part of the light strip housing 31, and at least one female buckle 4 is connected to the main body 1 of the measuring ruler. The male buckle 5 and the female buckle 4 are movably engaged. The movable engagement of the male buckle 5 and the female buckle 4 is simple to operate. The inspector only needs to align the male buckle 5 on the light strip housing 31 with the female buckle 4 on the measuring ruler body 1 and insert it to complete the assembly of the light strip assembly 3. This can save assembly time and improve work efficiency. When the light strip assembly 3 is no longer needed or when the measuring ruler body 1 is stored after inspection, the inspector can easily separate the male buckle 5 from the female buckle 4 and remove the light strip assembly 3 from the measuring ruler body 1.

[0034] like Figure 4 and Figure 5As shown, in some embodiments, the female buckle 4 has a slot 41, and the male buckle 5 has a protrusion 51, which slides and engages with the slot 41. By gently sliding the male buckle 5 along the direction of the slot 41, the male buckle 5 and the female buckle 4 can be engaged, ensuring that the light strip assembly 3 maintains a stable connection throughout the entire testing process, providing continuous and reliable illumination for the testing work. When assembling the light strip assembly 3, no excessive force or additional tools are required, making the operation convenient and quick. Furthermore, the structures of the male buckle 5 and the female buckle 4 are simple, resulting in low production costs.

[0035] like Figure 6 and Figure 7 As shown, in some embodiments, the connecting hinge 2 includes a first rotating connecting block 21 and a second rotating connecting block 22. The first rotating connecting block 21 and the second rotating connecting block 22 are connected to the measuring scale 11, and the first rotating connecting block 21 and the second rotating connecting block 22 are rotatably connected. The first rotating connecting block 21 and the second rotating connecting block 22 are rotatably connected and firmly connected to the measuring scale 11, which can ensure the stability of the measuring scale 11 during unfolding and use. The connecting hinge 2 allows the two measuring scales 11 of the measuring scale body 1 to rotate relative to each other. When the measuring scale is not in use, the two measuring scales 11 can be folded up by rotating the connecting hinge 2, which greatly reduces the space occupied by the measuring scale as a whole.

[0036] like Figure 6 and Figure 7 As shown, in some embodiments, the first rotating connecting block 21 is provided with a rotating connecting portion 211, and the rotating connecting portion 211 is provided with at least one connecting groove. The second rotating connecting block 22 is provided with a connecting protrusion 221, which is embedded in the connecting groove. A connecting shaft 23 passes through the central axis of the rotating connecting portion 211 and the connecting protrusion 221. The connecting protrusion 221 is embedded in the connecting groove, forming a tight mechanical connection. This tight fit can effectively prevent loosening or displacement between the two rotating connecting blocks during use, ensuring that the connection between the components of the measuring scale is stable and reliable during unfolding and folding. The connecting shaft 23 passes through the central axis of the rotating connecting portion 211 and the connecting protrusion 221, providing a stable rotation axis for the two rotating connecting blocks.

[0037] like Figure 7As shown, in some embodiments, each of the two measuring scales 11 is movably connected to a connecting screw 6 near the connecting hinge 2, and a connecting piece 7 is connected between the connecting screws 6. The connecting piece 7 is connected to the two measuring scales 11 through the connecting screws 6. When the measuring scales 11 are unfolded, the connecting piece 7 acts as a stable bridge, tightly connecting the two measuring scales 11 together, greatly enhancing the overall stability of the measuring scale. When the measuring scales 11 need to be unfolded, the inspector can quickly install the connecting piece 7 onto the measuring scales 11 through the connecting screws 6. After the inspection work is completed, the connecting piece 7 can be easily removed, facilitating the storage and carrying of the measuring scales.

[0038] like Figure 8 As shown, in some embodiments, the connecting piece 7 is provided with an elongated oval hole 71 and a connecting slot 72. One connecting screw 6 is connected to the elongated oval hole 71, and the other connecting screw 6 is connected to the connecting slot 72. One connecting screw 6 first passes through the elongated oval hole 71 to initially fix the connecting piece 7 to one measuring scale 11, and the other connecting screw 6 is first initially fixed to another measuring scale 11. When the two measuring scales 11 are unfolded, the elongated oval hole 71 allows the connecting piece 7 to adjust its position within a certain range, so that the connecting slot 72 of the connecting piece 7 can be connected to the connecting screw 6. The inspection personnel do not need to spend a lot of time to accurately align the hole position, which reduces the operational difficulty and time cost in the installation process, thereby improving the installation efficiency.

[0039] The working principle and process of this utility model for a road surface evenness detector are as follows: When the detector is needed, the two measuring rulers 11 are unfolded, and then the connecting screws 6 and connecting pieces 7 are locked onto the measuring ruler body 1 to ensure the stability of the measuring ruler body 1. Then, the male buckle 5 on the light strip assembly 3 is snapped into the female buckle 4 on the measuring ruler body 1, and the power cord of the LED light strip 32 is inserted into the interface of the power module 8 to complete the installation of the light strip assembly 3.
