This solves the problem that existing crack comprehensive testers usually lack the function of blocking light when conducting outdoor testing. When operating outdoors, light may shine directly on the surface of the crack comprehensive tester's display screen. Strong light will reduce the brightness of the display screen, resulting in a significant decrease in the contrast of images and text. Originally clear crack detection data, charts, and other information may become blurry and difficult to distinguish, making it difficult for operators to accurately read crack parameters.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crack detection device for municipal road construction, comprising a crack comprehensive tester, wherein a light-shielding component is provided on the front side of the crack comprehensive tester, and a control mechanism is provided on the top of the crack comprehensive tester.

[0006] In a preferred embodiment of this invention, the light-shielding component includes a support block. The rear side of the support block is fixedly connected to a crack comprehensive testing instrument. A light-shielding plate is rotatably connected to the inner side of the support block, and the light-shielding plate is made of an opaque material. A limiting post is provided on the left side of the support block. The right side of the limiting post penetrates the support block and extends to the inner side of the support block, where it is fixedly connected to the light-shielding plate. A limiting block is fixedly connected to the left side of the limiting post. A torsion spring is sleeved on the surface of the limiting post. The left and right sides of the torsion spring are fixedly connected to the limiting block and the support block, respectively.

[0007] As a preferred embodiment of the present invention, the traction assembly includes a winding reel, the surface of which is wound with a steel wire rope, and the right side of the winding reel is rotatably connected to the inner wall of the traction box.

[0008] As a preferred embodiment of this utility model, a rectangular through hole is provided on the front side of the inner wall of the traction box, one end of the wire rope is fixedly connected to the winding reel, and the other end of the wire rope passes through the rectangular through hole and extends to the outside of the rectangular through hole and is fixedly connected to the light shield.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model solves the problem that existing crack comprehensive testers, when used outdoors, typically lack the function of blocking light. When operating outdoors, light may shine directly on the surface of the crack comprehensive tester's display screen.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0022] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention, which provides a crack detection device for municipal road construction, including a crack comprehensive tester 1, a light-shielding component 2 disposed on the front side of the crack comprehensive tester 1, and a control mechanism 3 disposed on the top of the crack comprehensive tester 1. The control mechanism 3 includes a traction box 31 and a control box 32. The traction box 31 has a traction component 33 inside its cavity, and the control box 32 has a drive component 34 inside its cavity. The bottom of the traction box 31 is fixedly connected to the crack comprehensive tester 1, and the right side of the control box 32 is fixedly connected to the traction box 31.

[0023] Specifically, by setting up the traction box 31, the traction component 33 can be protected; by setting up the control box 32, the drive component 34 can be protected. By setting up the light-shielding component 2, light can be blocked to prevent direct light from shining on the display screen surface of the crack comprehensive tester 1, and the display screen of the crack comprehensive tester 1 can also be protected when not in use.

[0024] By setting the traction component 33, the shading component can be pulled, so that the shading component can be opened or closed, and the shading angle of the shading component can also be controlled.

[0025] By setting the drive component 34, the traction component 33 can be driven, and the position of the traction component 33 can be automatically fixed.

[0026] Furthermore, during use, the operator rotates the drive component 34, which in turn drives the traction component 33 to rotate. During the rotation of the traction component 33, the light-shielding component 2 is pulled, causing the light-shielding component 2 to rotate. When the light-shielding component 2 reaches the appropriate position, the operator stops rotating the drive component 34. When the drive component 34 stops rotating, the traction component 33 stops rotating, thereby fixing the position of the light-shielding component 2 and allowing the light-shielding component to block the light, making it easier for the operator to observe the data.

[0027] Example 2 The second embodiment of this utility model provides a crack detection device for municipal road construction. The light-shielding component 2 includes a support block 21. The rear side of the support block 21 is fixedly connected to the crack comprehensive tester 1. A light-shielding plate 22 is rotatably connected to the inner side of the support block 21. The light-shielding plate 22 is made of opaque material. A limit post 23 is provided on the left side of the support block 21. The right side of the limit post 23 passes through the support block 21 and extends to the inner side of the support block 21 and is fixedly connected to the light-shielding plate 22. A limit block 24 is fixedly connected to the left side of the limit post 23. A torsion spring 25 is sleeved on the surface of the limit post 23. The left and right sides of the torsion spring 25 are fixedly connected to the limit block 24 and the support block 21, respectively.

[0028] Specifically, by setting the support block 21, the light shield 22 can be supported. By setting the light shield 22, the light can be blocked, preventing strong light from directly shining on the display screen of the crack comprehensive tester 1. By setting the limiting post 23 and the limiting block 24, the torsion spring 25 can be supported and limited. By setting the torsion spring 25, the rebound force released after torsion can prevent the light shield 22 from being pulled to the appropriate position and then rotating backward, thus failing to block the light.

[0029] Furthermore, the traction component 33 pulls the light shield 22 to rotate in a circle with the support block 21, so that the light shield 22 no longer blocks the display screen of the crack comprehensive tester 1. During the rotation, the light shield 22 will also drive the limiting column 23 and the limiting block 24 to rotate synchronously and twist the torsion spring 25. The rebound force released after the torsion spring 25 is twisted can prevent the light-shielding plate 22 from rotating upward after it is pulled to a suitable angle, so that the traction component 33 is in a taut state. Furthermore, when the traction component 33 relaxes the light-shielding plate 22, it can facilitate the automatic reset of the light-shielding plate 22.

[0030] Example 3 The third embodiment of this utility model provides a crack detection device for municipal road construction. The traction component 33 includes a winding reel 331, on the surface of which a steel wire rope 332 is wound. The right side of the winding reel 331 is rotatably connected to the inner wall of the traction box 31.

[0031] A rectangular through hole 4 is provided on the front side of the inner wall of the traction box 31. One end of the wire rope 332 is fixedly connected to the winding reel 331, and the other end of the wire rope 332 passes through the rectangular through hole 4 and extends to the outside of the rectangular through hole 4 and is fixedly connected to the light shield 22.

[0032] Rotating columns 5 are provided at the top and bottom of the inner wall of the rectangular through hole 4. Both ends of the rotating columns 5 are rotatably connected to the inner wall of the rectangular through hole 4. The steel wire rope 332 is located between the two rotating columns 5.

[0033] Specifically, by setting up the winding reel 331, the wire rope 332 can be wound up. By setting up the wire rope 332, the light-blocking plate 22 can be opened during the winding process. By setting up the rectangular through hole 4, the wire rope 332 can be limited. By setting up the rotating column 5, the friction between the wire rope 332 and the rectangular through hole 4 during winding can be reduced.

[0034] Furthermore, the drive assembly 34 drives the winding reel 331 to rotate. During the rotation of the winding reel 331, the wire rope 332 is wound up. The wire rope 332 pulls the light-shielding plate 22 to rotate, opening the light-shielding plate 22. When the wire rope 332 is wound up, the rotating column 5 is rotatably connected to the inner wall of the rectangular through hole 4, which can also reduce the friction between the wire rope 332 and the rectangular through hole 4.

[0035] Example 4 The fourth embodiment of this utility model provides a crack detection device for municipal road construction. The drive assembly 34 includes a worm gear 341, a worm 342, and a control component 343. The left side of the worm gear 341 is rotatably connected to the inner wall of the control box 32, and the right side of the worm gear 341 is fixedly connected to a rotating shaft 344. The side of the rotating shaft 344 away from the worm gear 341 passes through the traction box 31 and extends into the inner cavity of the traction box 31, where it is fixedly connected to the winding reel 331.

[0036] The worm 342 is located in front of the worm wheel 341 and meshes with the worm wheel 341 at its rear. The bottom of the worm 342 is rotatably connected to the inner wall of the control box 32. The bottom of the control component 343 penetrates the control box 32 and extends into the inner cavity of the control box 32, where it is fixedly connected to the top of the worm 342.

[0037] Specifically, by setting the worm gear 341 and the rotating shaft 344, the winding reel 331 can be driven to rotate. By setting the worm 342, the worm gear 341 can be driven to rotate. The transmission of the worm gear 341 and the worm 342 has self-locking properties and can also fix the position of the winding reel 331, thereby fixing the position of the light shield 22. By setting the control component 343, it is easy for the operator to rotate the worm 342.

[0038] Furthermore, the operator rotates the control component 343, driving the worm gear 342 to rotate. The worm gear 342 drives the worm wheel 341 to rotate. During the rotation of the worm wheel 341, it drives the take-up reel 331 to rotate through the rotating shaft 344. Moreover, the transmission between the worm wheel 341 and the worm gear 342 has a self-locking property. When the operator stops rotating the control component 343, the take-up reel 331 will no longer rotate, thereby fixing the position of the take-up reel 331.

[0039] Working principle: In use, the operator rotates the control component 343 to drive the worm gear 342 to rotate. The worm gear 342 drives the worm wheel 341 to rotate. During the rotation of the worm wheel 341, it drives the winding reel 331 to rotate through the rotating shaft 344, thereby winding up the wire rope 332. During the winding process, the wire rope 332 will pull the light shield 22 to rotate around the support block 21, so that the light shield 22 will no longer block the display screen of the crack comprehensive tester 1. During the rotation, the light shield 22 will also drive the limit post 23 and the limit block 24 to rotate synchronously and twist the torsion spring 25. When the light-shielding plate 22 reaches the appropriate angle, the rotation control component 343 stops rotating. The worm gear 342 no longer drives the worm wheel 341 to rotate. Since the worm wheel 341 and worm gear 342 transmission has a self-locking property, when the worm gear 342 stops rotating, the worm wheel 341 cannot drive the worm gear 342 to rotate, thus fixing the position of the winding reel 331 and preventing the wire rope 332 from dragging the winding reel 331 to rotate in the opposite direction. This, in turn, fixes the position of the light-shielding plate 22, blocking the light and preventing the light from shining directly on the display screen of the crack comprehensive tester 1, making it easier for the operator to observe the data. Meanwhile, the rebound force released by the torsion spring 25 after it is twisted can prevent the light-shielding plate 22 from rotating upward after it is pulled to a suitable angle, thus preventing the steel wire rope 332 from bending and keeping the steel wire rope 332 in a taut state, thereby fixing the position of the light-shielding plate 22. Furthermore, when the steel wire rope 332 relaxes the light-shielding plate 22, the rebound force released by the torsion spring 25 can also assist the light-shielding plate 22 in automatically resetting.

[0040] In summary, by using the light-shielding component 2 and the control mechanism 3 in combination, the direct sunlight on the display screen of the crack comprehensive tester is prevented from affecting the operator's ability to read data.
