[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description 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. Example

[0042] like Figures 1-5 As shown, this embodiment provides a surveying and mapping beam frame measurement structure, including a ruler 10 with strip-shaped holes 11 along its length. The surveying and mapping beam frame measurement structure also includes a moving block 20, a shaft 30, and a measuring component 40. Figure 2 As shown, the movable block 20 has an embedding groove 21, which is slidably embedded in the ruler 10. The movable block 20 includes a U-shaped plate 22 and two ear plates 23. Ear plates 23 are fixed at both ends of the U-shaped plate 22, and the ends of the two ear plates 23 furthest from the U-shaped plate 22 are positioned opposite each other. The open end of the U-shaped plate 22 and one side of the two ear plates 23 form the embedding groove 21. A threaded hole 24 is formed on the side wall of the U-shaped plate 22, and a bolt 60 is threaded into the threaded hole 24. The bolt 60 abuts against the ruler 10. This completes the fixing of the movable block to the ruler 10. The bolt 60 is a wing bolt. The wing bolt facilitates manual rotation by the operator. Figure 1 , Figure 3 As shown, there are two shafts 30. One shaft 30 is fixed to the top of the ruler 10. The other shaft 30 is fixed to the movable block 20 and passes through the strip hole 11. Each shaft 30 is provided with a measuring element 40. Both measuring elements 40 include a first rod 41 and a second rod 42, as shown... Figure 1 As shown, one end of the first rod 41 is hinged to the shaft 30, and the other end of the first rod 41 is fixed to the rotating shaft 43. The second rod 42 is hinged to the rotating shaft 43, and the other end of the second rod 42 has a notch 420. Wherein, as... Figure 2 As shown, notch 420 is engaged on the shaft 30 of another measuring component 40, as... Figure 1The first rod 41 and the second rod 42 of the two measuring members 40 form a diamond structure 50, as shown. The top angle of the diamond structure is derived from the space angle between the beams. Figure 4 As shown, the notch 420 is separated from the shaft 30 of the other measuring member 40, so that the first rod 41 and the second rod 42 of each measuring member 40 are in a collinear state.

[0043] The ruler 10 is attached to the surface of the beam to be measured. The measuring position is adjusted by sliding the moving block 20 on the ruler 10. The strip hole 11 of the ruler 10 is matched with the embedded groove 21 of the moving block 20, which ensures the smooth displacement of the moving block 20 along the length direction, as shown. Figure 4 As shown, the notch 420 is separated from the shaft 30 of the other measuring member 40, so that the first rod 41 and the second rod 42 of each measuring member 40 are in a collinear state, so that the distance between the two measuring members is the linear distance between the two points of the beam. Further, when measuring the space angle between the beams, the first rod 41 of the two measuring members 40 is rotated around the shaft 30, and the second rod 42 is linked through the rotating shaft 43. The end of the second rod 42 of one of the measuring members 40 is clamped to the shaft 30 of the other measuring member 40, forming a diamond structure 50. Under the diamond structure 50, the space angle between the beams is derived from the angle between the first rod 41 and the second rod 42 of the measuring member 40. Through such a structure, the distance between the beams and the space angle between the beams can be measured.

[0044] As shown, Figure 3As shown, one end of the shaft 30 is coaxially connected to the first limiting column 31, and one end of the first rod 41 is located between the first limiting column 31 and the ruler 10. One end of the rotating shaft 43 is coaxially connected to the second limiting column (not labeled), and one end of the second rod 42 is located between the second limiting column and the first rod 41. The end of the first rod 41 away from the rotating shaft 43 and the end of the second rod 42 away from the notch 420 are both provided with mounting holes 400, which are sleeved on the shaft 30 or the rotating shaft 43. The first rod 41 and the second rod 42 are both provided with sliding grooves 401 and connecting grooves 402 along the length direction, and the sliding grooves 401 and the connecting grooves 402 form a T-shaped groove 403. One end of the sliding groove 401 communicates with the mounting hole 400, and the sliding plate 45 is slidingly arranged in the sliding groove 401. The push plate 46 is fixedly arranged on the sliding plate 45, and the end of the push plate 46 away from the sliding plate 45 penetrates out of the connecting groove 402. The shaft 30 and the rotating shaft 43 are both provided with insertion grooves 404, and one end of the sliding plate 45 can be inserted into the insertion grooves 404. When the first rod 41 and the second rod 42 of each measuring piece 40 are in a collinear state, the sliding plate 45 is inserted into the insertion grooves 404, so that the first rod 41 and the second rod 42 of one measuring piece 40 are in a collinear state, and the first rod 41 and the second rod 42 form a rigid straight rod structure for measuring the spacing data of the beam frame. When it is necessary to make the notch 420 clamped on the shaft 30 of another measuring piece 40, so that the first rod 41 and the second rod 42 of the two measuring pieces 40 form a rhombus structure 50, the sliding plate 45 is in a separated state with the insertion grooves 404, so as to measure the angle data of the beam frame. Manually pushing the push plate 46 can move the sliding plate 45 in the sliding groove 401.

[0045] The side wall of the notch 420 is provided with a mounting groove 421, and the mounting groove 421 is fixedly arranged with a spring 49. The spring 49 is arranged along the length direction of the second rod 42, and the free end of the spring 49 is fixedly arranged with a blocking block 47, which is slidingly arranged in the mounting groove 421. When the spring 49 is in a free state, the blocking block 47 abuts against the opposite side wall of the mounting groove 421, and the blocking block 47 blocks the notch 420. The end of the blocking block 47 away from the spring 49 is provided with an inclined surface 471, which can abut against the shaft 30. When the spring 49 is in a free state, the blocking block 47 is tightly abutted against the opposite side wall of the mounting groove 421 under the elastic force of the spring 49. By rotating the second rod 42, the inclined surface 471 can abut against the shaft 30, the spring 49 is further compressed, and the shaft 30 is located between the notch 420 and the blocking block 47, so that the shaft 30 is difficult to be separated from the notch 420 without human intervention.

[0046] Obviously, the embodiments described are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.
