[0041] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] like Figure 1~Figure 4 As shown, this embodiment proposes a level for outdoor work, including a level body 1, and also includes a support frame 2, a walking track 3, a buffer mechanism, an adaptive anti-fall mechanism and an installation box 4. The walking track 3 is fixedly connected to the bottom end of the support frame 2, the buffer mechanism is installed at the bottom end of the level body 1, and the adaptive anti-fall mechanism is installed on the support frame 2, wherein the adaptive anti-fall mechanism includes an installation box 4, and the installation box 4 is fixedly connected to the top of the support frame 2. When moving, the level body 1 will be subjected to the force of the bumpy ground, which may cause damage to the level. At this time, the buffer mechanism is started to offset the force by allowing the level body 1 to swing slightly, thereby protecting the safety of the level body 1. Due to the complex outdoor terrain, when the level is working outdoors, the uneven ground may cause the level to fall over. When the level falls over, the adaptive anti-fall mechanism operates to support the level body 1 in time to prevent the level body 1 from being damaged.

[0043] Among them, the buffer mechanism includes a semicircular plate 5, a mounting tube 6, a rotating rod 7, a limit rod 8 and a limit hole 9. The semicircular plate 5 is fixedly connected to the bottom end of the level body 1, and the mounting tube 6 is fixedly connected to the top of the mounting box 4. There are two rotating rods 7, and the two rotating rods 7 are symmetrically arranged. The two rotating rods 7 are respectively fixedly connected to the two ends of the semicircular plate 5, and the two rotating rods 7 are rotatably connected to the mounting tube 6. There are two limit rods 8, and the two limit rods 8 are symmetrically arranged. The two limit rods 8 are respectively slidably connected to the two ends of the semicircular plate 5. There are two limit holes 9, and the two limit holes 9 are respectively matched with the two limit rods 8. The two limit holes 9 are opened on both sides of the semicircular plate 5. When the buffer mechanism is working, the limit rod 8 is pulled out from the limit hole 9, and then the semicircular plate 5 can shake slightly in the mounting tube 6 when encountering bumps, so as to protect the level body 1 from being damaged by force or affecting the accuracy.

[0044] Secondly, the adaptive anti-fall mechanism includes a support assembly, a rotating assembly, an installation cavity and an electric cylinder 10. There are two support assemblies, which are installed on both sides of the support frame 2. The rotating assembly is installed at a position of the support assembly close to the installation box 4. The installation cavity is opened in the installation box 4. There are four electric cylinders 10, which are fixedly connected in the installation cavity. The output ends of the four electric cylinders 10 are fixedly connected to the support assembly. When the level falls over, the gravity sensor transmits the falling signal to the control system, thereby opening the electric cylinder 10. The electric cylinder 10 pushes the support assembly, so that the support assembly cooperates with the rotating assembly to support and reduce shock on the level body 1.

[0045] Again, the supporting assembly includes a supporting plate 11, a spring shock-absorbing rod 12 and a supporting rod 13. There are two supporting plates 11, which are located on both sides of the width direction of the level body 1. There are four spring shock-absorbing rods 12, which are respectively fixedly connected to the two supporting plates 11. There are four supporting rods 13, which are respectively fixedly connected to the four spring shock-absorbing rods 12. The output ends of the four electric cylinders 10 are rotatably connected to the four supporting rods 13, respectively. The supporting assembly works by pushing the supporting rods 13 by the electric cylinders 10 to prevent the level body 1 from being bumped. First, the electric cylinders 10 push the supporting rods 13 to open, providing good support. At the same time, the spring shock-absorbing rods 12 can play a shock-absorbing role.

[0046] Among them, the rotating assembly includes a mounting plate 14, a rotating plate 15 and a rotating shaft 16. There are two mounting plates 14, which are fixedly connected to the mounting box 4. The two mounting plates 14 are fixedly connected to both sides of the width direction of the level body 1. There are two rotating plates 15, which are respectively rotatably connected to the two mounting plates 14. The top ends of the four support rods 13 are respectively fixedly connected to the two mounting plates 14. There are two rotating shafts 16, which are respectively rotatably connected to the two mounting plates 14. The two rotating shafts 16 are respectively rotatably connected to the two rotating plates 15. When the electric cylinder 10 pushes the support rod 13, the support rod 13 cooperates with the opening angle through the rotating plate 15 and the rotating shaft 16 to make the support better and protect the level body 1 well.

[0047] Finally, a plurality of matching grooves 17 are provided at the bottom end of the support plate 11. The matching grooves 17 can adapt to more terrains. When there are uneven slopes on the outdoor ground, the matching grooves 17 can better stick to the ground and keep the level body 1 stable during operation.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
