Description

Technical Field

[0001] The utility model relates to the technical field of angle measurement, in particular to an angle measuring instrument for road construction. Background Art

[0002] Angle measuring devices play a vital role in road construction and many other fields. They accurately measure the angles between objects, providing crucial data support for precise layout and installation during the construction process. For example, in road construction, angle measuring devices can be used to determine the slope and angle of curves, ensuring smoothness and safety. In building construction, they can also help construction workers determine the angles of buildings, ensuring their structural stability and aesthetics.

[0003] Existing angle measuring devices are bulky and lack the ability to fold or fold, which can be quite inconvenient when transporting them. Their bulk not only increases transportation costs but also requires significant storage space at the construction site. For workers who frequently move and measure across different locations, carrying such large angle measuring devices can be cumbersome, reducing work efficiency. To improve this, a new angle measuring instrument for road construction is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-7 :

[0026] Overall structure and function:

[0027] This angle measuring instrument primarily consists of a base 1 and a folding plate 2, providing a precise and convenient tool for angle measurement during road construction. The base 1 serves as the instrument's foundational support. Its rotating opening 4, movable opening 6, and transmission chamber 11 interact with each other to achieve the key function of angle measurement. The folding plate 2 is connected to the base 1 via a rotating shaft, allowing it to rotate flexibly to accommodate various measurement requirements. During use, the transmission mechanism, connection mechanism, and mounting mechanism work together to accurately measure the desired angle value, which is intuitively displayed via a pointer 7 and scale 8.

[0028] Transmission mechanism:

[0029] The transmission mechanism consists of a driving gear 12 mounted on the rotating shaft of the folding plate 2 and a transmission gear 13 mounted on the screw 5. Both the driving gear 12 and the transmission gear 13 are bevel gears, and the two are vertically meshed. This design allows the rotation of the folding plate 2 to be effectively transmitted to the screw 5, thereby driving the movement of the pointer 7. The use of bevel gears ensures the stability and accuracy of the transmission, and can operate reliably in various complex construction environments. When the folding plate 2 rotates, the driving gear 12 rotates accordingly, and through meshing with the transmission gear 13, the rotation is transmitted to the screw 5, causing the screw 5 to rotate within the rotation port 4.

[0030] Bridging Institutions:

[0031] The connection mechanism includes a connection frame 10 threadedly mounted on the screw 5, with the pointer 7 mounted on the connection frame 10. As the screw 5 rotates, the threads cause the connection frame 10 to move along the screw 5. This allows the pointer 7 to move within the movable opening 6 as the screw 5 rotates, accurately indicating the angle between the folding plate 2 and the base 1. This threaded connection ensures that the movement of the pointer 7 closely matches the rotation of the screw 5, improving measurement accuracy.

[0032] Mounting mechanism:

[0033] The mounting mechanism includes a fixed rod 14 mounted within the movable slot 9, a positioning frame 15 with a connecting slot 16, and a spring within the connecting slot 16. The ends of the spring are elastically connected to the outer wall of the fixed rod 14 and the inner wall of the connecting slot 16, respectively. This design allows the positioning frame 15 to move flexibly within the movable slot 9 while maintaining a certain degree of stability due to the spring. When the folding panel 2 is to be opened for use, the positioning frame 15 is moved, causing it to compress the spring and release the other end from the positioning slot 3.

[0034] Inclined part design:

[0035] Both the folding plate 2 and the positioning frame 15 are equipped with inclined portions, each of which is polished. This design makes it easier for the positioning frame 15 to be inserted into the positioning slot 3, improving operational convenience. The polished surface not only looks good but also reduces friction, extending the life of the measuring instrument.

[0036] When the utility model is used, Figure 1 As shown, the folding plate 2 is in the open state. At this time, the folding plate 2 can fit the surface of the object whose angle needs to be measured. When the folding plate 2 is in the vertical state, the pointer 7 is located in the middle position of the scale 8, and the surface angle is 90 degrees at this time. When the folding plate 2 rotates to fit the surface of the object whose angle needs to be measured, the folding plate 2 will rotate, so the screw 5 will be driven to rotate with the help of the driving gear 12 and the transmission gear 13. When the screw 5 rotates, the connecting frame 10 will move, thereby driving the pointer 7 to move. When the pointer 7 moves closer to or away from the screw 5, the angle will change. The above-mentioned scale 8 corresponds to the rotation amplitude of the driving gear 12 and the transmission gear 13, showing the change of angle.

[0037] In this solution, when there is no need to measure the angle, the folding plate 2 is rotated to make it horizontal and stored in the base 1. During the folding and storage process, the positioning frame 15 finally enters the positioning groove 3 to complete the fixed folding of the folding plate 2. After folding, the overall area occupied by the device becomes smaller and easier to carry.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
