Specific implementation manners

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figure 1 , an embodiment provided by the present utility model: A protractor for portable ancient building design includes a middle column 1. The top of the middle column 1 is fixedly connected with an angle adjustment platform 2. The middle column 1 supports and fixes the angle adjustment platform 2. The top of the angle adjustment platform 2 is rotatably connected with a measuring component for adjusting the measuring angle. The measuring component includes a cylinder 12. The outside of the cylinder 12 is rotatably connected to one side of the inner wall of the angle adjustment platform 2. The angle adjustment platform 2 supports the cylinder 12. The other end of the cylinder 12 is rotatably connected with a support rod 13. Starting the cylinder 12 can push the support rod 13.

[0033] The bottom of the support rod 13 is rotatably connected to the inner middle part of the angle adjustment platform 2, and the angle adjustment platform 2 plays a supporting role for the support rod 13. The top of the support rod 13 is rotatably connected to the bottom of the measurement platform 15. The movement of the support rod 13 can push the measurement platform 15 to move to one side. Since the first cylinder 12 is located at the right end of the angle adjustment platform 2, it pushes the support rod 13 to move to the left end, causing the top of the measurement platform 15 to also move to the left end. At one end of the inner wall of the angle adjustment platform 2 away from the first cylinder 12, a second cylinder 14 is rotatably connected. The angle adjustment platform 2 plays a supporting role for the second cylinder 14. The other end of the second cylinder 14 is rotatably connected to the measurement platform 15. Starting the second cylinder 14 causes the measurement platform 15 to be pushed. The second cylinder 14 is located at the left end of the angle adjustment platform 2, so it pushes the measurement platform 15 to move to the right.

[0034] An infrared detector 16 is installed on the top of the measurement platform 15. The infrared detector 16 here refers to the existing technology on the market. It mainly uses a laser ruler and infrared point positioning to transmit the data of the overall model diagram of the building to the software, and an angle ruler is added to measure the angles in details. The functions of the first cylinder 12 and the second cylinder 14 make the top of the measurement platform 15 face different positions, thereby driving the infrared detector 16 to receive different positions of the building, so that the overall building can be measured better and the angle measurement can be more accurate.

[0035] Refer to Figures 2 to 4 , three support columns 3 are rotatably connected to the bottom of the angle adjustment platform 2. The three support columns 3 rotate independently at the bottom of the angle adjustment platform 2. When in use, the positions of the three support columns 3 can be adjusted to a triangular shape and surround the middle column 1, making the bracket more stable. When not in use, the three support columns 3 are moved closer to the middle column 1, reducing the space volume of the bracket and making it easy to carry.

[0036] A telescopic rod 4 (as shown in the appendix Figure 4 ) is slidably connected inside each of the three support columns 3. The telescopic rod 4 is used to extend the length of the three support columns 3. Practically, it is to adjust the height of the bracket so that the bracket can be applicable to buildings of different heights. At the bottom of each of the three telescopic rods 4, a universal wheel 5 (as shown in the appendix Figure 2 ) is fixedly connected, so that when the parameters such as the height and angle of the bracket are adjusted, the bracket can move freely with the operator without the need to move first and then adjust, reducing the working time occupied by the measuring tool and making the measuring work more efficient.

[0037] At the bottom of each of the three support columns 3, a locking ring 6 is fixedly connected. Inside each of the three locking rings 6, a rotating column 9 is rotatably connected. Inside each of the three locking rings 6, a notch is formed. At both ends of each of the three rotating columns 9, they are slidably connected to the inner wall of the notch. When unlocking the position fixation between the three telescopic rods 4 and the support columns 3, pulling the three handles 8 will drive the three rotating columns 9 to move outwards. The movement of the three rotating columns 9 will drive the movement of the three sliding plugs 10, causing the three sliding plugs 10 to disengage from the three sliding channels, which means unlocking the position of the three telescopic rods 4. On the other side of the outside of each of the three rotating columns 9, a handle 8 is fixedly connected. After determining the external display length of the telescopic rod 4, the three handles 8 can be rotated to make the three rotating columns 9 rotate.

[0038] On one side of the outside of each of the three rotating columns 9, a sliding plug 10 is rotatably connected. The rotation of the three rotating columns 9 will push the three sliding plugs 10 towards the inner middle part of the locking ring 6. On one side of the outside of each of the three telescopic rods 4, a sliding channel is formed. The other ends of the three sliding plugs 10 are slidably connected to the inner wall of the sliding channel. The three sliding plugs 10 are engaged into the three sliding channels to lock the position of the three telescopic rods 4 (as shown in the attached Figure 4 ). On the outside of each of the three locking rings 6, a connecting rod 11 is rotatably connected, so that when the three support columns 3 rotate, they can drive the three locking rings 6 to move away from or close to each other. The other ends of the three connecting rods 11 are rotatably connected to a sliding ring 7, so that the three connecting rods 11 can pull the sliding ring 7 to slide on the outside of the middle column 1. The inside of the sliding ring 7 is slidably connected to the outside of the middle column 1 (as shown in the attached Figure 2 ), which has a certain fixing effect on the spreading of the three support columns 3, so that the three support columns 3 will not spread too much and cause the angle-adjusting platform 2 to contact the ground, damaging the infrared detector 16 on its top.

[0039] Refer to Figure 5 , a window is formed inside the angle-adjusting platform 2. A fixing plate 17 is fixedly connected inside the angle-adjusting platform 2. The angle-adjusting platform 2 has a supporting and fixing effect on the fixing plate 17. The outside of the fixing plate 17 is fixedly connected to the inner wall of the window. The top inner wall of the window is fixedly connected to a thin line 18. The window has a function of fixing the position of the thin line 18. The other end of the thin line 18 is fixedly connected to a center-measuring block 19. The center-measuring block 19 has a certain weight. On one side of the outside of the fixing plate 17, a center-marking block 20 is fixedly connected. In the static state, if the thin line 18 pulled by the center-measuring block 19 is straightened and can be aligned with the center-marking block 20 (as shown in the attached Figure 5 ), it indicates that the angle-adjusting platform 2 is in a horizontal state at this time. A slot is formed in the inner middle part of the fixing plate 17, and the thin line 18 passes through it, so that when the thin line 18 is in a straightened state, it is more convenient to compare its position with the center-marking block 20.

[0040] Working principle: Pull the three telescopic rods 4 respectively to adjust the height of the bracket to adapt to the building to be measured. Push the three handles 8 to drive the three rotating columns 9. The pushing of the three rotating columns 9 causes the three sliding plugs 10 to be pushed until the three sliding plugs 10 are exactly engaged with the inner wall of the slideway of the three telescopic rods 4, so as to determine the height of the bracket. Rotate the three support columns 3 so that the three support columns 3 can be distributed in a triangular shape away from the bottom of the angle adjustment platform 2, drive the three connecting rods 11 to rotate, and pull the sliding rings 7 at the other ends of the three connecting rods 11 to slide on the outside of the middle column 1, making the support of the three support columns 3 more stable. If it is not needed, the three support columns 3 can be rotated in the reverse direction so that the three support columns 3 are folded towards the outside of the middle column 1. Universal wheels 5 are fixedly connected to the bottoms of the three telescopic rods 4, so that during the measurement process, if it is necessary to change the measurement position, there is no need to store the bracket again, and only the bracket needs to be pushed to follow the operator's movement. After adjusting the measurement bracket, observe whether the thin line 18 can be aligned with the standard block 20 after the measurement block 19 is stationary. If it is aligned, it indicates that the angle adjustment platform 2 is horizontal at this time. Otherwise, it is necessary to adjust the three support columns 3 to keep the angle adjustment platform 2 horizontal, making the subsequent measurement results more accurate. Start the first cylinder 12 to push the support rod 13, so that the support rod 13 pushes the measurement table 15, making the top of the measurement table 15 deflect to the left front. Start the second cylinder 14 to push the measurement table 15, making the top of the measurement table 15 deflect to the right front. The combined action of the two makes the infrared detector 16 on the top of the measurement table 15 able to completely detect the building object, making the measurement result more accurate.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
