However, this patent cannot fix the angle of the unfolded measuring ruler, making it difficult to obtain accurate angle values, which ultimately affects the accuracy of the measurement results and cannot provide a reliable basis for quality control of the roadbed construction slope, which may affect the quality and safety of the entire construction project.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: Please refer to Figure 1A roadbed construction slope detection ruler comprises a base 1 and a measuring plate 2. The measuring plate 2 is rotatably mounted on the top of the base 1 through a pin shaft. An angle disc 3 for intuitively reading angle data is fixedly mounted on the outer surface of the base 1 through bolts. A pointer 4 for indicating a value is fixedly mounted on the outer wall of the measuring plate 2 through a pin shaft, and the pointer 4 is located on the outer wall of the angle disc 3. By pulling the measuring plate 2 to rotate around the pin shaft, the pointer 4 connected to the measuring plate 2 rotates accordingly, and the pointer 4 indicates a corresponding value on the angle disc 3, so as to intuitively read the slope angle data;

[0025] A positioning structure for angular positioning of the measuring plate 2 is fixedly installed at the right end of the base 1, an auxiliary structure for assisting the measuring plate 2 in slope detection is fixedly installed in the inner cavity of the base 1, and a fixed structure for accommodating the measuring plate 2 is fixedly installed at one end of the base 1 away from the positioning structure.

[0026] See also Figure 1 , Figure 2 , Figure 3 The positioning structure includes an outer cover 501, which is fixedly mounted on the upper right side of the base 1. The inner cavity of the outer cover 501 is rotatably connected to a rotating rod 502 for driving the measuring plate 2 to rotate, and both ends of the rotating rod 502 are fixedly connected to the measuring plate 2. A ratchet 503 is fixedly sleeved on the outer wall of the rotating rod 502, and a plurality of ratchets 504 for limiting the rotation angle of the measuring plate 2 are rotatably connected to the inner wall of the outer cover 501;

[0027] Specifically, the inner wall of the outer cover 501 is rotatably connected with a plurality of rotating shafts 505 through bearings, and each rotating shaft 505 is fixedly connected with a pawl 504, and each pawl 504 is meshed with a ratchet 503. The measuring plate 2 is pulled to drive the rotating rod 502 to drive the ratchet 503 to rotate counterclockwise. The pawl 504 cooperates with the ratchet 503. When the ratchet 503 rotates counterclockwise, the pawl 504 will slide through the tooth grooves of the ratchet 503 in sequence. Once the pulling of the measuring plate 2 stops, the pawl 504 will immediately get stuck in the tooth groove of the ratchet 503, limiting the reverse rotation of the ratchet 503, thereby limiting the rotation angle of the measuring plate 2, so that the measuring plate 2 is stabilized at the current measuring position, effectively avoiding accidental rotation of the measuring plate 2 due to external interference or improper operation, and ensuring the accuracy and stability of the measurement data.

[0028] The positioning structure also includes a toothed ring 506, which is rotatably mounted in the inner cavity of the outer cover 501. A gear 507 is mounted on one end of each pawl 504 away from the ratchet wheel 503, and the gear 507 is meshed with the toothed ring 506. When the toothed ring 506 rotates, the gear 507 is driven to rotate, and then the pawl 504 rotates and no longer meshes with the ratchet wheel 503.

[0029] Specifically, each gear 507 is fixedly sleeved on the outer wall of the rotating shaft 505, and a driving rod 508 for driving the gear ring 506 to rotate is fixedly installed on one side of the gear ring 506, and one end of the driving rod 508 away from the gear ring 506 is inserted into the inner part of the outer cover 501;

[0030] More specifically, a rotation groove for providing rotation for the driving rod 508 is formed on the outer wall of the outer cover 501, and the driving rod 508 is located in the rotation groove. In the initial state, the driving rod 508 is at the bottom of the rotation groove. When the measuring plate 2 is subjected to external interference and rotates unexpectedly, the ratchet 503 generates a force to push the pawl 504 to drive the gear ring 506 to rotate clockwise. Since the driving rod 508 is at the bottom of the rotation groove, there is no space for rotation, thereby limiting the reversal of the measuring plate 2.

[0031] Example 2: Please refer to Figure 1 , Figure 4 The auxiliary structure includes a pressing plate 601, which is located above the base 1. The bottom surface of the pressing plate 601 is fixedly connected with a plurality of connecting frames 602. The interior of each connecting frame 602 is rotatably connected with a moving wheel 603 for driving the base 1 to move through a pin shaft;

[0032] A plurality of return springs 604 are installed between the pressing plate 601 and the base 1 to control the upward movement and retraction of the moving wheel 603, and the upper and lower ends of each return spring 604 are fixedly connected to the pressing plate 601 and the base 1 respectively;

[0033] Specifically, the inner cavity of the base 1 is provided with a movable groove for providing movement of the movable wheel 603, and the movable wheel 603 is located in the movable groove. The pressing plate 601 is pushed by the reset spring 604 to drive the movable wheel 603 to retract into the movable groove for easy storage. When the base 1 needs to be moved for slope detection, the pressing plate 601 is manually pressed down to push the movable wheel 603 to protrude from the base 1, so that the movable wheel 603 contacts the ground, providing rolling support for the base 1.

[0034] See also Figure 1 , Figure 5 The fixed structure includes a flip buckle 701, which is rotatably connected to the base 1 through a pin shaft, and a buckle frame 702 is rotatably connected to the outer wall of the flip buckle 701. A limit block 703 is fixedly installed on one side of the measuring plate 2, and the buckle frame 702 is sleeved on the outer wall of the limit block 703;

[0035] Specifically, a groove for preventing the buckle frame 702 from slipping is formed at the top of the outer wall of the limiting block 703, and the buckle frame 702 is located in the groove.

[0036] See also Figure 1 , Figure 4A plurality of silicone blocks 8 for assisting the positioning of the device are fixedly mounted on the side away from the base 1 and the measuring plate 2. The silicone blocks 8 can also reduce the wear on the surface of the device.

[0037] The working principle of the utility model is:

[0038] First, pull the measuring plate 2 to rotate around the pin shaft so that the measuring plate 2 fits the slope. Since the measuring plate 2 is fixedly connected to the rotating rod 502, the rotating rod 502 drives the ratchet 503 to rotate counterclockwise. At this time, the pawl 504 slides between the teeth of the ratchet 503. When the measuring plate 2 rotates to a suitable position to fit the slope, stop pulling. The pawl 504 immediately gets stuck in the teeth of the ratchet 503 to limit its reverse rotation, thereby fixing the angle of the measuring plate 2. At the same time, the pointer 4 connected to the measuring plate 2 through the pin shaft rotates synchronously, indicating the corresponding value on the angle disk 3, so as to intuitively read the slope angle data.

[0039] When the angle of the measuring plate 2 needs to be adjusted, the driving rod 508 is rotated to drive the gear ring 506 to rotate. Since the gear ring 506 is meshed with the gear 507, the gear 507 drives the rotating shaft 505 to rotate accordingly, so that the ratchet 504 rotates around the rotating shaft 505 and disengages from the ratchet 503, thereby releasing the rotation restriction of the measuring plate 2 and allowing the measuring plate 2 to be pulled again to adjust the angle.

[0040] Then, manually press down the pressing plate 601 located above the base 1, and the pressing plate 601 overcomes the elastic force of the return spring 604, driving the connecting frame 602 and the internally rotatably connected moving wheel 603 to move downward, so that the moving wheel 603 protrudes from the base 1 and contacts the ground, providing rolling support for the base 1. After pressing the pressing plate 601, the measuring plate 2 is continuously pushed to move along the slope, so as to detect whether the overall angle of the slope is consistent;

[0041] Finally, the flip buckle 701 is rotated to cover the buckle frame 702 on the outer wall of the limit block 703, and the buckle frame 702 is located in the groove at the top of the limit block 703 to prevent the buckle frame 702 from slipping, thereby fixing the measuring plate 2 for overall storage.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
