Technical Field

[0001] The utility model belongs to the technical field of building engineering surveying and mapping equipment, and particularly relates to a building engineering surveying and mapping device. Background Technique

[0002] A building engineering surveying and mapping device is a device specifically used for building engineering measurement and surveying tasks. These devices can include various measuring instruments, tools, and equipment for obtaining information such as the dimensions, shapes, positions, and heights of buildings. Among them, a level is a relatively common and essential device, which can detect whether a building is horizontal or inclined and provide a reference line for adjustment.

[0003] During the fine adjustment of the horizontal angle of the existing building engineering surveying and mapping device, most of them rotate the three threaded support rods respectively to adjust the lifting of one corner of the surveying and mapping instrument to achieve the horizontal adjustment effect. However, this method is relatively cumbersome and requires multiple rotation adjustments of the screw rods respectively, reducing the use effect. Therefore, we propose a building engineering surveying and mapping device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a building engineering surveying and mapping device to solve the problem of low efficiency when the existing building engineering surveying and mapping device fine-tunes the horizontal angle as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A building engineering surveying and mapping device includes a surveying and mapping instrument. A first mounting hole is provided at the bottom of the surveying and mapping instrument. A connection plate is provided at the bottom of the surveying and mapping instrument. A connection screw rod is provided at the top of the connection plate. A horizontal bubble disk is provided on one side of the connection plate. Connection holes are provided at the edge of the connection plate. A fastening bolt is provided inside the connection hole. A grip rod is provided on one side of the connection plate. A hemisphere is provided at the bottom of the connection plate. An installation seat is provided below the connection plate. A hemispherical groove is provided at the top of the installation seat. A perforation is provided on one side of the installation seat. A fastening screw rod is provided inside the perforation. A second mounting hole is provided at the bottom of the connection plate.

[0006] Preferably, a first mounting hole is fixedly opened in the middle of the bottom side of the surveying and mapping instrument. The surveying and mapping instrument and the connection plate are fixedly connected by threading between the connection screw rod and the first mounting hole.

[0007] Preferably, a horizontal bubble disk is fixedly connected to one side of the connection plate. The connection holes are obliquely opened at the edge of the connection plate. There are three groups of connection holes, which are evenly distributed in a circle at the edge of the connection plate. A fastening bolt is threadedly rotated inside the connection hole. One side of the top end of the fastening bolt is a plane.

[0008] Preferably, a grip rod is fixedly connected to one side of the connecting plate, and a hemisphere is fixedly installed at the bottom of the connecting plate.

[0009] Preferably, a hemispherical groove is fixedly formed at the top of the mounting base, the hemisphere is rotatably limited inside the hemispherical groove, a perforation is fixedly formed on one side of the mounting base, and the inside of the perforation communicates with the inside of the hemispherical groove.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4, the present utility model provides a technical solution: a building engineering surveying and mapping device, including a surveying instrument 1. A first mounting hole 2 is provided at the bottom of the surveying instrument 1. A connecting disk 4 is provided at the bottom of the surveying instrument 1. A connecting screw 3 is provided at the top of the connecting disk 4. A horizontal bubble disk 5 is provided on one side of the connecting disk 4. Connecting holes 6 are provided at the edge of the connecting disk 4. A fastening bolt 7 is provided inside the connecting hole 6. A grip rod 8 is provided on one side of the connecting disk 4. A hemispherical body 9 is provided at the bottom of the connecting disk 4. An installation base 10 is provided below the connecting disk 4. A hemispherical groove 11 is provided at the top of the installation base 10. A through hole 12 is provided on one side of the installation base 10. A fastening screw 13 is provided inside the through hole 12. A second mounting hole 14 is provided at the bottom of the connecting disk 4.

[0020] Specifically, a first mounting hole 2 is fixedly opened in the middle of the bottom side of the surveying instrument 1. The surveying instrument 1 and the connecting disk 4 are fixedly connected by screw threads between the connecting screw 3 and the first mounting hole 2. A horizontal bubble disk 5 is fixedly connected to one side of the connecting disk 4. Connecting holes 6 are obliquely opened at the edge of the connecting disk 4. There are three groups of connecting holes 6, which are evenly distributed in a circle at the edge of the connecting disk 4. A fastening bolt 7 is rotationally connected by screw threads inside the connecting hole 6. One side of the top end of the fastening bolt 7 is a plane. A grip rod 8 is fixedly connected to one side of the connecting disk 4. A hemispherical body 9 is fixedly installed at the bottom of the connecting disk 4. A hemispherical groove 11 is fixedly opened at the top of the installation base 10. The hemispherical body 9 is rotationally limited and arranged inside the hemispherical groove 11. A through hole 12 is fixedly opened on one side of the installation base 10. The inside of the through hole 12 communicates with the inside of the hemispherical groove 11. A fastening screw 13 is threadedly connected inside the through hole 12. A second mounting hole 14 is fixedly opened in the middle of the bottom side of the connecting disk 4.

[0021] In this embodiment, when in use, first rotate and threadedly connect the first mounting hole 2 at the bottom of the surveying instrument 1 with the connecting screw 3 above the connecting disk 4, so as to preliminarily connect and fix the surveying instrument 1 and the connecting disk 4. Then rotate the fastening bolt 7, and the fastening bolt 7 will move upward inside the connecting hole 6 until the inclined plane at the top end of the fastening bolt 7 abuts against the bottom of the surveying instrument 1, thereby increasing the stable effect of the surveying instrument 1 above the connecting disk 4 and making up for the weak instability caused by the gap between the bottom side of the surveying instrument 1 and the surface of the connecting disk 4. By rotationally connecting the second mounting hole 14 with the bolt rod at the top of the triangular bracket, the connecting disk 4, the installation base 10, and the surveying instrument 1 can be fixed above the triangular bracket. When adjusting the horizontal angle of the surveying instrument 1, loosen the fastening screw 13, and adjust the horizontal position of the hemispherical body 9 at the lower end of the connecting disk 4 inside the hemispherical groove 11 above the installation base 10 through the grip rod 8. The horizontal angle of the connecting disk 4 and the surveying instrument 1 above can be judged through the horizontal bubble disk 5. Finally, tighten the fastening screw 13 to abut against one side of the hemispherical body 9 inside the hemispherical groove 11, thereby completing the fixing effect of the connecting disk 4 and the surveying instrument 1 and improving the working efficiency of the device.
