DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0036] A specific embodiment of the utility model is as follows Figure 1As shown, a leveling structure is disclosed, including a leveling module 1, a tripod module 2 and a support leg module 3.

[0037] like Figure 2 As shown, the leveling module 1 includes a leveling seat 11, a buckle 12, a bubble level 13 and a leveling compass assembly 14. The leveling seat 11 is a rectangular frame, and first protrusions are arranged on the outside of three sides of the leveling seat 11, and a second protrusion is arranged on the outside of another side.

[0038] In order to enable the leveling mechanism to be quickly disassembled, a buckle 12 is fixed to the outside of the first protrusion by screws to adapt to equipment that requires a working reference surface. Compared with the prior art, this embodiment uses a buckle 12 to connect external equipment instead of screws and other fixings, which has strong adaptability and is easy to disassemble.

[0039] A groove is provided below the first protrusion near the outer edge, and the leveling compass assembly 14 is provided in the groove. The leveling compass assembly 14 is used to adjust the up and down position of the leveling seat 11, and includes a leveling compass 141, a fastening screw sleeve 142, and a leveling shaft 143. The leveling compass 141 is fixed in the groove of the first protrusion by the fastening screw sleeve 142. The leveling shaft 143 is located inside the fastening screw sleeve 142 and the leveling compass 141, and is coaxially arranged with the leveling compass 141. The leveling shaft 143 has an external thread on the outside, and the leveling compass 141 has an internal thread. The leveling compass 141 can drive the leveling shaft 143 to rotate, thereby completing the up and down micro-movement of the leveling seat 11.

[0040] The width of the second protrusion is smaller than that of the first protrusion. A through hole is arranged on the second protrusion, and a bubble level 13 is installed in the through hole for level measurement.

[0041] The tripod module 2 is located between the leveling module 1 and the support leg module 3. Figure 3 and Figure 4 As shown, the tripod module 2 includes a support leg adjustment seat assembly 21, a tripod fixing plate 23, a frustum 27 and a compass fixing frame 26.

[0042] The compass fixing frame 26 is provided with a plurality of threaded holes, in which fixing screws 25 are provided. In order to fix the leveling module 1 tightly to the tripod module 2 to prevent looseness from affecting the leveling and leveling measurement, an anti-loosening compression spring 24 is provided below the fixing screws 25.

[0043] The compass fixing frame 26 is also provided with a plurality of through holes for passing the leveling shaft 143. A cone 27 is provided below the compass fixing frame 26, and a groove is provided at the position corresponding to the threaded hole of the cone 27. The leveling shaft 143 in the leveling module 1 can pass through the through hole of the compass fixing frame 26 and abut against the groove of the cone 27. At this time, tighten the fixing screw 25 to compress the anti-loosening compression spring 24, so as to realize the connection between the leveling module 1 and the tripod module 2.

[0044] The support leg adjustment seat assembly 21 is used to fix the support leg 31. The support leg adjustment seat assembly 21 and the support leg 31 support the leveling module 1 and the external device by forking the three support legs 31 at a certain angle. The size of the forking angle is adjusted by the support leg adjustment seat assembly 21. The support leg 31 is used for the initial rough leveling. The support leg adjustment seat assembly 21 can determine the bearing force by adjusting the cross angle between the support legs 31 to achieve a fixed position and a force point.

[0045] The support leg adjustment seat assembly 21 includes a support leg adjustment seat 211 , a support leg transfer screw 212 , an adjustment baffle 214 and an adjustment tension spring 215 .

[0046] The support leg adjustment seat assembly 21 is fixed on the tripod fixing plate 23 through the screw fixing shaft 22. The upper part of the support leg adjustment seat 211 is provided with an adjustment baffle fixing screw 213 for connecting the adjustment baffle 214; the lower part is provided with a support leg transfer screw 212 for installing the support leg module 3. The adjustment baffle 214 is combined with the adjustment tension spring 215 to achieve the angle adjustment of the support leg adjustment seat assembly 21. The adjustment baffle 214 can be pulled outward, and the support leg adjustment seat 211 is rotated, and the adjustment baffle 214 is buckled on the corresponding tooth position. The elastic effect of the adjustment tension spring 215 is used to tightly buckle the adjustment baffle 214 on the corresponding tooth position.

[0047] The support leg module 3 includes a support leg 31 and a claw at the end. A connecting threaded hole is provided in the middle of the upper part of the support leg 31, and the support leg adapter screw 212 is screwed in to complete the connection between the support leg module 33 and the tripod module 2. The support leg 31 is a telescopic structure with a multi-section telescopic rod, which can be used as a secondary rough leveling to be telescoped to a required length according to the terrain requirements.

[0048] The end of the bracket leg 31 is provided with a claw. Figure 5 (a) Figure 5 (b) and Figure 5 As shown in (c), in order to adapt to different terrains, the claws include a sole-type claw 321, a conical claw 322 and a multi-tooth claw 323. The sole-type claw 321 is suitable for soft soil and sand environment, the conical claw 322 is suitable for mountainous terrain, and the multi-tooth structure is suitable for ice terrain.

[0049] The method of using this embodiment is as follows: first, select the appropriate bracket leg 31 claw according to the terrain conditions, and connect the bracket leg module 3 to the tripod module 2. This can be achieved by screwing the bracket leg 31 into the bracket leg adjustment seat 211 in the tripod module 2; secondly, connect the leveling module 1 to the tripod module 2. When connecting, loosen the fixing screw 25, extend the leveling shaft 143 of the leveling module 1 into the through hole of the compass fixing frame 26, press against the groove of the cone 27, tighten the fixing screw 25, and press the anti-loosening spring 24; finally, install the external device to the leveling mechanism through the buckle 12 of the leveling module 1.

[0050] After the installation is completed, the support angle of the bracket legs 31 is adjusted according to the weight of the external equipment and the terrain conditions, and the support points of the bracket legs 31 are determined. This is the first rough leveling.

[0051] According to the terrain conditions, the length of the support legs 31 is adjusted, which is the second rough leveling.

[0052] The leveling compass 141 is rotated to perform final fine leveling on the leveling seat 11 to complete the leveling work.

[0053] Compared with the prior art, the present embodiment provides a multi-module assembly, including a leveling seat module 1, a tripod module 2, and a support leg module 3; the leveling seat module 1 and the tripod module 2 are connected by screws and tightened with an anti-loosening compression spring 24; the tripod module 2 and the support leg module 3 are screwed together by a support leg adapter screw 212, which is simple in method and easy to install. The connection method between the modules is highly universal, which is convenient for disassembly, replacement and later maintenance.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
