Description

Technical Field

[0001] This utility model relates to the field of engineering surveying technology, and in particular to a level instrument for engineering surveying. Background Technology

[0002] Leveling instruments are used to record data during engineering surveying. However, they have some shortcomings and deficiencies in use, which need improvement as follows: 1. Typical leveling instruments are supported by tripods. The conical structure at the bottom of the tripod poses a significant risk when carried, and its sharp points make it difficult to support and erect on slopes or other terrain conditions. 2. Leveling instruments are inconvenient to observe in strong sunlight. Therefore, we propose a new leveling instrument for engineering surveying. Utility Model Content

[0003] The main purpose of this utility model is to provide a level instrument for engineering surveying, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A level instrument for engineering surveying includes a fixed plate. Three sets of support mechanisms are evenly spaced at the lower end of the fixed plate. A connecting rod is threadedly inserted and snapped into the middle of the fixed plate. A connecting plate is threadedly inserted and snapped into the upper part of the connecting rod. The level instrument body is arranged on the upper part of the connecting plate. A shielding mechanism is fixedly connected to the front and rear of the upper end of the level instrument body.

[0005] Preferably, the support mechanism includes a telescopic support leg and a rectangular block. A threaded fixing rod is provided at the lower left end of the telescopic support leg. A magnetic ring is fixedly connected to the lower surface of the telescopic support leg. External cones are fixedly connected to the front and rear lower ends of the telescopic support leg. Receiving grooves are formed at the front and rear upper ends of the rectangular block. Balls are fixedly connected to the front and rear lower ends of the rectangular block. By adopting the above technical solution, the magnetic ring attracts and fixes to the lower rectangular block, thus covering and enveloping the lower external cones.

[0006] Preferably, the telescopic support leg is connected to the fixed plate via a pivot, the rectangular block is made of metal, and the sphere is made of rubber. By adopting the above technical solution, the rubber sphere increases friction with the ground, thereby improving the stability of the support.

[0007] Preferably, the blocking mechanism includes two sets of locking slots, front and rear. Each set of locking slots has a circular hole on its left side. A rectangular frame is locked between the two sets of locking slots. Cylindrical rods are fixedly connected to the four corners of the upper end of the rectangular frame. A blocking plate is fixedly connected to the upper ends of the four sets of cylindrical rods. Circular holes are formed at the left front and left rear of the rectangular frame. Springs are fixedly connected to the inner walls of the two sets of circular holes on the rectangular frame. Fixing rods are fixedly connected to the two sets of springs. By adopting the above technical solution, the position of the upper blocking plate can be fixed by locking the fixing rods with the circular holes on the rectangular frame.

[0008] Preferably, the lower ends of both sets of locking slots are fixedly connected to the upper end of the level instrument body, and the fixing rod is inserted and locked into the round hole on the rectangular frame. By adopting the above technical solution, the shielding plate can easily shield the lower part of the level instrument body, reducing the influence of light.

[0009] Preferably, the shield is light-colored. By adopting the above technical solution, a light-colored shield can absorb light.

[0010] This utility model has the following beneficial effects: Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a support mechanism, the outer cone on the support mechanism can adapt to conditions such as gravel roads, while the sphere at the bottom of the rectangular block can be used on flat ground or slopes, increasing the applicability. In addition, the lower rectangular block can wrap around the outer cone, reducing the risk of carrying it.

[0011] 2. By setting up a shielding mechanism, the shielding plate on the shielding mechanism can easily shield the lower part of the level instrument body, making it easier to observe the lower part of the level instrument body. At the same time, the fixing rod can easily install or fix the upper shielding plate. Attached Figure Description

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Please see Figure 1-4 This utility model provides a technical solution: A level instrument for engineering surveying includes a fixed plate 1. Three sets of support mechanisms 2 are equally spaced at the lower end of the fixed plate 1. A connecting rod 3 is threadedly inserted and snapped through the middle of the fixed plate 1. A connecting plate 4 is threadedly inserted and snapped through the upper part of the connecting rod 3. A level instrument body 5 is set on the upper part of the connecting plate 4. A blocking mechanism 6 is fixedly connected to the front and rear of the upper end of the level instrument body 5.

[0018] In this embodiment, the support mechanism 2 includes a telescopic support leg 7 and a rectangular block 8. A threaded fixing rod 9 is provided at the lower left end of the telescopic support leg 7. A magnetic ring 10 is fixedly connected to the lower surface of the telescopic support leg 7. External cones 11 are fixedly connected to the front and rear lower ends of the telescopic support leg 7. Receiving grooves 12 are provided at the front and rear upper ends of the rectangular block 8. Spheres 13 are fixedly connected to the front and rear lower ends of the rectangular block 8. The telescopic support leg 7 is connected to the fixing plate 1 via a pivot. The rectangular block 8 is made of metal, and the spheres 13 are made of rubber. Through this design, the external cones 11 at the bottom of the support mechanism 2 can be conveniently used for support on muddy or gravelly roads, and the spheres 13 at the bottom of the rectangular block 8 can be conveniently used on flat ground and slopes, increasing the applicability. Furthermore, the external cones 11 can be wrapped up during transport, reducing risk.

[0019] In this embodiment, the blocking mechanism 6 includes two sets of locking slots 14, one at the front and one at the back. Each set of locking slots 14 has a round hole 15 on its left side. A rectangular frame 16 is locked between the two sets of locking slots 14. A cylindrical rod 17 is fixedly connected to the four corners of the upper end of the rectangular frame 16. A blocking plate 18 is fixedly connected to the upper end of the four sets of cylindrical rods 17. A round hole 15 is opened at the left front end and the left rear end of the rectangular frame 16. A spring 19 is fixedly connected to the inner wall of each of the two sets of round holes 15 on the rectangular frame 16. A fixing rod 20 is fixedly connected to each of the two sets of springs 19. The lower ends of the two sets of locking slots 14 are fixedly connected to the upper end of the level instrument body 5. The fixing rod 20 is inserted and locked into the round hole 15 on the rectangular frame 16. The blocking plate 18 is set to a light color. With the above solution, the shielding plate 18 on the shielding mechanism 6 can conveniently shield the lower structure to prevent light from affecting the observation effect of the lower level instrument body 5. At the same time, the fixing rod 20 on the rectangular frame 16, which is connected by the spring 19, is engaged with the round hole 15 on the snap-fit ​​groove 14 to fix or disassemble it.

[0020] It should be noted that this utility model is a level instrument for engineering surveying. During use, first, the level instrument body 5 is fixed to the upper part of the fixing plate 1. Determine the usage conditions. If it is a gravel road or muddy ground, remove the rectangular block 8 from the lower part of the telescopic support leg 7, exposing the lower outer cone 11. Insert the outer cone 11 into the gravel road or muddy ground. After stretching the support mechanism 2 outwards, adjust the angle of the upper level instrument body 5 and adjust it to a horizontal line. Then, compress the fixing rod 20, which is fixedly connected to the spring 19, inwards. After the rectangular frame 16 passes through the two sets of snap-fit ​​grooves 14, it extends... Pushing to the right causes the fixing rod 20 to engage with the circular hole 15 on the locking groove 14, fixing the position of the rectangular frame 16. The rectangular frame 16 is fixedly connected to the shielding plate 18 by the cylindrical rod 17 to shield the lower structure, which can effectively prevent strong light from affecting the observation results. If it is flat or on a slope, the rubber ball 13 fixedly connected to the lower part of the rectangular block 8 can contact the plane. At the same time, the rubber material increases the friction with the plane, which can effectively improve the support force of the lifting support mechanism 2 on the upper part and prevent the risk of the external cone 11 when carrying.
