Description

Technical Field

[0001] This utility model relates to the field of slope measurement technology, and in particular to an auxiliary device for measuring the slope of urban and rural road models. Background Technology

[0002] In the design, production and evaluation of urban and rural road models, road slope is a key parameter. Accurately measuring the road model slope is of great significance for ensuring that the model meets the design requirements and simulates the actual road conditions. The common auxiliary tool for measuring road slope is the slope meter.

[0003] Currently, existing slope meters require operators to bring the measuring surface of the instrument into contact with the surface to be measured to determine the road slope. However, after use, the measuring surface remains exposed. Consequently, when the slope meter is stored in a toolbox, it rubs against other tools or the inner wall of the packaging box during transportation. Over time, this increases the surface roughness and reduces the flatness of the measuring surface, affecting the degree of contact between the meter and the object being measured and the accuracy of the measurement. To address these issues, we propose an auxiliary device for slope measurement of urban and rural road models. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary measuring device for measuring the slope of urban and rural road models.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An auxiliary device for measuring the slope of a model of urban and rural roads includes a slope meter. A protective frame is movably fitted at the bottom of the slope meter, and grooves are symmetrically formed on the inner wall of the bottom of the protective frame. A fixed shaft is fixedly connected to the inner wall of the grooves, and a rotating plate is movably fitted on the outer side of the fixed shaft. A flipping plate is fixedly connected to the adjacent sides of the rotating plate. A torsion spring is connected to the side of the rotating plate, and the other end of the torsion spring is connected to the inner wall of the groove. Connecting rods are symmetrically distributed above the protective frame, and a linkage block is fixedly connected to the top of each connecting rod. The linkage block and the top of the connecting rod are inserted into the inside of a connecting sleeve. An insertion rod is horizontally inserted into the side of one set of connecting sleeves. A pull block is fixedly connected to one end of the insertion rod, and the other end of the insertion rod extends into the connecting rod. Two sets of limiting grooves adapted to the connecting rod are formed inside the connecting rod.

[0007] Preferably, rubber blocks are fixedly connected to the side of the protective frame, and the rubber blocks are distributed at the corners of the protective frame.

[0008] Preferably, a connecting spring is laterally connected to the inner side of the pull block, and the other end of the connecting spring is connected to the outer wall of the connecting sleeve.

[0009] Preferably, the top of the protective frame is provided with a mating groove that matches the connecting rod, the inner wall of the protective frame is horizontally inserted with a threaded rod, and the end of the threaded rod is fixedly connected with a rotating block, and the bottom of the connecting rod is provided with a threaded groove that matches the threaded rod.

[0010] Preferably, there are two sets of connecting springs, and the two sets of connecting springs are symmetrically distributed about the central axis of the pull block.

[0011] Preferably, the cross-sectional area of ​​the rotating block is larger than that of the threaded rod, and a rectangular plate is connected to the side of the rotating block away from the threaded rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This device, equipped with a protective frame and a flip plate, can cover and protect the measuring surface at the bottom of the slope meter when it is not in use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 An auxiliary device for measuring the slope of a model road in urban and rural areas includes a slope meter 1. A protective frame 2 is movably fitted onto the bottom of the slope meter 1, and grooves 3 are symmetrically formed on the inner wall of the bottom of the protective frame 2. The slope measurement principle of the slope meter 1 is existing technology and will not be described in detail here. A fixed shaft 4 is fixedly connected to the inner wall of the groove 3, and a rotating plate 5 is movably fitted onto the outer side of the fixed shaft 4. A flipping plate 6 is fixedly connected to the adjacent sides of the rotating plate 5. A torsion spring 16 is connected to the side of the rotating plate 5, and the other end of the torsion spring 16 is connected to the inner wall of the groove 3. Since the rotating plate 5 is movably fitted onto the outer side of the groove 3, the flipping requirements of the rotating plate 5 and the flipping plate 6 can be met. The protective frame 2... Connecting rods 7 are symmetrically distributed at the top, and each connecting rod 7 is fixedly connected to a linkage block 9. The linkage block 9 and the top of the connecting rod 7 are inserted into the inside of the connecting sleeve 8. A insertion rod 10 is inserted horizontally on the side of one set of connecting sleeves 8. Through the cooperation of the two sets of connecting rods 7 and connecting sleeves 8, the stability of the protective frame 2 when moving up and down can be effectively guaranteed. Only one set of connecting sleeves 8 has a insertion rod 10 inserted horizontally at the bottom, which makes it easy for the staff to quickly adjust the position of the protective frame 2 by pulling the pull block 11. One end of the insertion rod 10 is fixedly connected to the pull block 11, and the other end of the insertion rod 10 extends into the connecting rod 7. The inside of the connecting rod 7 is provided with two sets of limiting grooves that are compatible with the connecting rod 7.

[0023] Furthermore, refer to Figure 2 It can be seen that rubber blocks 15 are fixedly connected to the side of the protective frame 2, and the rubber blocks 15 are distributed at the corners of the protective frame 2. During use, the distribution of four sets of rubber blocks 15 can achieve buffer protection at the corners of the protective frame 2.

[0024] Furthermore, refer to Figure 5It can be seen that the inner side of the pull block 11 is connected to the connecting spring 12, and the other end of the connecting spring 12 is connected to the outer wall of the connecting sleeve 8. Through the elastic force of the connecting spring 12 itself, the tightness of the insertion rod 10 when it is inserted into the inner limiting groove of the connecting rod 7 can be effectively guaranteed.

[0025] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the top of the protective frame 2 is provided with a mating groove that matches the connecting rod 7, the inner wall of the protective frame 2 is horizontally inserted with a threaded rod 13, and the end of the threaded rod 13 is fixedly connected with a rotating block 14. The bottom of the connecting rod 7 is provided with a threaded groove that matches the threaded rod 13. During use, the operator can rotate the rotating block 14 to insert the threaded rod 13 into the connecting rod 7 or pull it out from the bottom of the connecting rod 7 to separate the protective frame 2 and the connecting rod 7, thereby enabling the replacement of the damaged protective frame 2 or the reuse of the intact protective frame 2.

[0026] Furthermore, refer to Figure 5 It can be seen that there are two sets of connecting springs 12, and the two sets of connecting springs 12 are symmetrically distributed about the central axis of the pull block 11. The connection of the two sets of connecting springs 12 can effectively ensure the balance when the pull block 11 is pulled laterally.

[0027] Furthermore, refer to Figure 4 It can be seen that the cross-sectional area of ​​the rotating block 14 is larger than that of the threaded rod 13. A rectangular plate is connected to the side of the rotating block 14 away from the threaded rod 13. During use, the rectangular plate makes it easy for the operator to quickly rotate the rotating block 14. Due to its large lateral area, the end of the threaded rod 13 can be limited to ensure the tightness of the connection between the connecting rod 7 and the protective frame 2.

[0028] Working Principle: In use, the operator first pulls the pull block 11 laterally, which moves the insertion rod 10 laterally to pull it out of the limiting groove at the top of the connecting rod 7. Then, the operator pushes the protective frame 2 upward, causing the connecting rod 7 distributed above the protective frame 2 to slide along the inner wall of the connecting sleeve 8. During the upward movement of the protective frame 2, the flip plate 6 is pushed, causing it to rotate the rotating plate 5 along the inner wall of the fixed shaft 4, allowing the flip plate 6 to rotate 90 degrees. This allows the protective frame 2 to be lifted smoothly. When the operator lifts the flip plate 6 above the measuring surface, the operator can stop pulling the pull block 11 laterally. The insertion rod 10 is forced into the limiting groove on the bottom wall of the connecting rod 7, thereby limiting the protective frame 2. Then, the operator can place the inclinometer 1 in the measurement area to measure the slope. After the measurement is completed, the operator can pull the pull block 11 horizontally again, which will push the protective frame 2 and the flip plate 6 downward. When the flip plate 6 is no longer in contact with the inner wall of the inclinometer 1, the flip plate 6 and the rotating plate 5 can be reset by the elastic force of the torsion spring 16 to cover and protect the bottom measuring surface of the inclinometer 1. Then, the insertion rod 10 can be inserted into the limiting groove at the top of the connecting rod 7 to limit the protective frame 2. The above is the complete working principle of this utility model.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
