For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0022] As Figures 1 to 4 shown, the embodiment of the present utility model provides a wall shape sampling instrument, which includes a handheld grip 1, a sampling mechanism and a travel mechanism 2. The sampling mechanism includes a sampling round tube 3, a pen mounting structure 4 and a sampling structure 5. In practical applications, the materials of the handheld grip 1 and the sampling round tube 3 are both selected as ABS engineering plastics. Not only are the material prices relatively cheap and the mechanical properties excellent, but also they can withstand a certain impact load, have good corrosion resistance, and can work in special environments.

[0023] As Figure 1As shown, the sampling structure 5 is connected to the first end of the sampling circular tube 3, and the end of the sampling structure 5 facing away from the sampling circular tube 3 is in contact with the wall surface to be measured. The pen mounting structure 4 is connected to the second end of the sampling circular tube 3, and the end of the pen mounting structure 4 facing away from the sampling circular tube 3 is used to mount a pen so that the axis of the pen is parallel to the wall surface to be measured. The handheld grip 1 is sleeved on the sampling circular tube 3, and the handheld grip 1 can drive the sampling circular tube 3 to move. In practical applications, the operator horizontally moves the handheld grip 1, and the handheld grip 1 drives the sampling circular tube 3 to move horizontally, so that the sampling circular tube 3 can drive the sampling structure 5 to move horizontally along the wall surface to be measured.

[0024] In the embodiment of the present application, the traveling mechanism 2 is connected to the handheld grip 1 and can move along the construction working surface perpendicular to the wall surface to be measured following the handheld grip 1. In practical applications, the traveling mechanism 2 can not only ensure that the handheld grip 1 is always parallel to the construction working surface, that is, ensure that the sampling circular tube 3 is always parallel to the construction working surface, but also facilitate the movement of the handheld grip 1.

[0025] When the wall shape sampling instrument provided by the embodiment of the present application is in use, first, a construction working surface perpendicular to the wall surface to be measured is built. Then, the wall shape sampling instrument is placed on the construction working surface, and the end of the sampling structure 5 facing away from the sampling circular tube 3 is in contact with the wall surface to be measured. Then, the operator horizontally moves the wall shape sampling instrument through the handheld grip 1, so that the wall shape of the wall surface to be measured is transmitted to the pen through the sampling structure 5, so that the pen draws the wall shape on the drawing during the movement, and thus an image on the construction working surface is obtained. Finally, different construction working surfaces are built again, and the above operations are repeated to obtain a complete image of the wall surface to be measured. The wall shape sampling instrument of the present application can measure the detailed shapes of various wall surfaces, improve the accuracy of wall shape sampling, so that the building components installed based on the wall shape have a higher degree of fit. In addition, the results measured by the present application are more intuitive than those measured by existing measuring instruments and are convenient for construction personnel to understand.

The first end of the elastic element 6 is connected to the sampling circular tube 3, and the second end of the elastic element 6 is connected to the handheld grip 1. In actual use, the handheld grip 1 is movably connected to the sampling circular tube 3, and the elastic element 6 is provided to ensure that the operation by the operator is more convenient, avoid sampling deviation caused by personal force deviation, and thus improve the sampling accuracy.

[0027] As Figure 1As shown, the wall shape sampling instrument also includes a first connecting member 7 and a second connecting member 8. One end of the first connecting member 7 is connected to the sampling tube 3, and the other end is connected to the first end of the elastic element 6. One end of the second connecting member 8 is connected to the handheld handle 1, and the other end is connected to the second end of the elastic element 6. In practical applications, the first connecting member 7 and the second connecting member 8 are used to install the elastic element 6.

[0028] like Figure 2 As shown, the wall shape sampling instrument also includes a latch 9. A first mounting hole is provided on the sampling circular tube 3. A second mounting hole corresponding to the first mounting hole is provided on the handheld handle 1. The latch 9 passes through the second mounting hole and is detachably connected to the first mounting hole. In practical applications, the latch 9 can prevent relative movement between the sampling circular tube 3 and the handheld handle 1. Specifically, when the wall to be measured is approximately flat, the latch 9 is passed through the second mounting hole and connected to the first mounting hole; when the wall to be measured is an irregular shape, the latch 9 can be unplugged.

[0029] like Figure 3 As shown, the pen mounting structure 4 includes a first connecting rod 41 and a pen mounting member 42. The first connecting rod 41 is connected to the sampling tube 3, and one end of the first connecting rod 41 away from the sampling tube 3 is connected to the pen mounting member 42. In the embodiment of the present application, the pen mounting member 42 is an annular structure with a threaded hole in the side wall. When the pen is inserted into the annular structure, a bolt is screwed into the threaded hole, and the threaded end of the bolt is abutted against the side wall of the pen to fix the pen.

[0030] like Figure 4 As shown, the sampling structure 5 includes a second connecting rod 51, a mounting rod 52, a bearing 53 and two cross bars 54. The second connecting rod 51 is connected to the sampling tube 3, and one end of the second connecting rod 51 away from the sampling tube 3 is connected to two cross bars 54. Both ends of the mounting rod 52 are respectively connected to one end of the two cross bars 54 away from the second connecting rod 51. The inner ring of the bearing 53 is connected to the mounting rod 52. When the wall shape sampling instrument is used, the outer ring of the bearing 53 contacts the wall to be measured and can roll along the wall to be measured.

[0031] In practical applications, the walking mechanism 2 includes a plurality of rollers 21. The plurality of rollers 21 are all connected to the handheld handle 1.
