DETAILED DESCRIPTION

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 4As shown, an auxiliary structure for a level provided by an embodiment of the utility model includes a level 1 and a tripod 2, the top of the tripod 2 is movably connected to the bottom of the level 1, the bottom of the level 1 is fixedly connected with a mounting shell 3, the top of the tripod 2 is provided with a mounting groove 4 for use with the mounting shell 3, the surface of the mounting shell 3 is in contact with the inner cavity of the mounting groove 4, the top of the inner cavity of the mounting shell 3 is fixedly connected with a fixing column 5, the bottom of the fixing column 5 is movably connected with a control block 6 through a rotating shaft, the bottom of the control block 6 passes through the mounting shell 3 and extends to the outside of the inner cavity of the mounting shell 3, and a limiting device 7 is arranged inside the mounting shell 3.

[0022] refer to Figure 4 The limiting device 7 includes four limiting blocks 701. The side of the limiting block 701 away from the fixing column 5 passes through the mounting shell 3 and extends to the outside of the inner cavity of the mounting shell 3. A stabilizing hole 702 is opened on the surface of the limiting block 701. The side of the limiting block 701 close to the fixing column 5 is fixedly connected with a spring 703. The side of the spring 703 close to the fixing column 5 is fixedly connected to the surface of the fixing column 5.

[0023] With the above solution, by providing the limiting device 7 , when the level 1 needs to be installed on the tripod 2 , the limiting device 7 has a limiting effect on the position of the level 1 .

[0024] refer to Figure 4 Four stabilizing blocks 8 used in conjunction with the stabilizing holes 702 are fixedly connected to the top of the inner cavity of the mounting shell 3 , and the surfaces of the stabilizing blocks 8 are movably connected to the inner cavity of the stabilizing holes 702 .

[0025] By adopting the above solution: by setting the stabilizing block 8, when the limit block 701 moves, the stabilizing hole 702 will be driven to move along the surface of the stabilizing block 8. The coordinated use of the stabilizing hole 702 and the stabilizing block 8 has a limiting effect on the moving position of the limit block 701.

[0026] refer to Figure 4 A pressing frame 9 is fixedly connected to the surface of the control block 6 close to the limit block 701 . There are four pressing frames 9 , which are evenly distributed on the surface of the control block 6 .

[0027] The above solution is adopted: by providing the extrusion frame 9 , when the control block 6 rotates, the extrusion frame 9 will be driven to move along the surface of the extrusion block 10 , and the extrusion frame 9 can generate an extrusion force on the extrusion block 10 .

[0028] refer to Figure 4 The bottom of the limiting block 701 is fixedly connected with an extrusion block 10 used in conjunction with the extrusion frame 9 , and the surface of the extrusion block 10 is in contact with the inner cavity of the extrusion frame 9 .

[0029] The above solution is adopted: by setting the extrusion block 10, the extrusion block 10 will move when it is subjected to the extrusion force of the extrusion frame 9, and when the extrusion block 10 moves, it can drive the limit block 701 to move.

[0030] refer to Figure 2 The inner cavity of the installation groove 4 is provided with a limiting groove 11 used in conjunction with the limiting block 701 , and the surface of the limiting block 701 contacts the inner cavity of the limiting groove 11 . The number of limiting grooves 11 is several and evenly distributed in the inner cavity of the installation groove 4 .

[0031] The above scheme is adopted: by setting the limit groove 11, when the mounting shell 3 is completely moved to the inner cavity of the mounting groove 4, the control block 6 is released, and the restoring force generated by the spring 703 restoring its shape will drive the limit block 701 to be stuck into the inner cavity of the limit groove 11. The coordinated use of the limit block 701 and the limit groove 11 has a limiting effect on the position of the mounting shell 3.

[0032] refer to Figure 2 and Figure 3 Four plug-in blocks 12 are fixedly connected to the bottom of the level 1, and four plug-in slots 13 for use with the plug-in blocks 12 are opened on the top of the tripod 2, and the surface of the plug-in block 12 contacts the inner cavity of the plug-in slot 13.

[0033] The above solution is adopted: by setting the plug-in block 12 and the plug-in slot 13, when the level 1 moves, the plug-in block 12 will be driven to move into the inner cavity of the plug-in slot 13. The coordinated use of the plug-in block 12 and the plug-in slot 13 has a limiting effect on the moving position of the level 1 and the mounting shell 3.

[0034] The working principle of this utility model:

[0035] During use, when it is necessary to conveniently and stably install the level 1 used in construction projects on the tripod 2, the operator first places the mounting shell 3 in the inner cavity of the mounting slot 4. When the mounting shell 3 moves, it will drive the level 1 to move to the top of the tripod 2, and at the same time drive the plug-in block 12 to move to the inner cavity of the plug-in slot 13, and then rotate the control block 6 to drive the control block 6 to rotate at the bottom of the fixed column 5 through the rotating shaft. When the control block 6 rotates, it will drive the extrusion frame 9 to rotate along the surface of the extrusion block 10. The extrusion block 10 subjected to the extrusion force will move toward the side close to the fixed column 5. When the extrusion block 10 moves, it will drive the limit block 701 to move toward the side close to the fixed column 5. When the limit block 701 moves, it can drive the stabilizing hole 702 along the stabilizing block 8 The surface moves, and the force generated when the limit block 701 moves causes the spring 703 to undergo elastic deformation. When the limit block 701 is completely moved to the inner cavity of the mounting shell 3, the mounting shell 3 can continue to be moved downward. The movement of the mounting shell 3 drives the plug-in block 12 and the level 1 to move. When the mounting shell 3 is completely moved to the inner cavity of the mounting slot 4, the plug-in block 12 is completely moved to the inner cavity of the plug-in slot 13, and at the same time, the bottom of the level 1 contacts the top of the tripod 2, the control block 6 is released. The restoring force generated by the spring 703 restoring its shape will drive the limit block 701 to be stuck into the inner cavity of the limit slot 11. The coordinated use of the limit block 701 and the limit slot 11 has a limiting effect on the position of the level 1 and the tripod 2. At this time, the level 1 used in the construction project is conveniently and stably installed on the tripod 2.

[0036] To sum up: the auxiliary structure of the level instrument solves the problem that a stable and flat reference point needs to be found when installing the existing construction engineering level instrument by setting a limit device 7, a limit block 701, a stabilizing hole 702, a spring 703 and a limit groove 11. A supporting tool such as a tripod or a metal tripod can be used, and then the level instrument is placed on it. The level instrument is usually connected to the tripod by bolt connection. When the bolts are connected, the position of the threaded holes and the bolts must be accurately matched, and then the tightness of the bolts must be continuously adjusted. The torque of the bolts is difficult to control, and it takes a long time and is not convenient enough. In addition, the bolts are prone to aging or stripping after long-term use, resulting in unstable installation. However, the levels used in existing construction projects do not have a component that can be conveniently and stably installed on the tripod.
