[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 An embodiment of this utility model provides a surveying tripod anti-settlement device, including a connecting cylinder 9, a connecting component 1 below the connecting cylinder 9, an adjusting component 2 below the connecting component 1, an anti-settlement plate 3 below the adjusting component 2, and three insert rods 4 fixedly installed below the anti-settlement plate 3. Sliding bottom grooves 302 are symmetrically arranged at the front and rear ends of the anti-settlement plate 3, and the sliding bottom grooves 302 are T-shaped grooves. An extension plate 5 is movably arranged inside the sliding bottom groove 302, and a stabilizing plate 6 is fixedly installed above the extension plate 5.

[0024] By setting up anti-settlement plates as the support surface for the surveying tripod, the contact area with the ground is increased, preventing localized sinking of the legs. The three insert rods can be effectively inserted into the ground, enhancing the tripod's grip. Meanwhile, the extension plate 5 can be extended laterally to further expand the support range. This allows for flexible adjustment of the support area according to the actual ground conditions, further dispersing pressure and resisting ground deformation, thereby effectively preventing settlement and ensuring that the measuring instrument remains in a stable and level state, thus increasing its practicality.

[0025] Please see Figure 1 and Figure 2 The front and rear ends of the anti-settlement plate 3 are symmetrically provided with long slots 301, which are connected to the sliding bottom groove 302. The front and rear ends of the anti-settlement plate 3 are symmetrically provided with fixing bolts 7, and the screw end of the fixing bolt 7 passes through the long slot 301 and is threadedly connected to the stabilizing plate 6.

[0026] The connection between the elongated slot 301 and the sliding bottom groove 302 allows the sliding stroke of the extension plate 5 to be adjusted, and the support area can be flexibly controlled according to actual needs. The fixing bolt 7 is threaded to the stabilizing plate 6 through the elongated slot 301, which realizes the quick locking and releasing of the extension plate 5.

[0027] Please see Figure 1 The connecting cylinder 9 has a fixing screw 10 symmetrically threaded on both sides. One end of the fixing screw 10 is inserted into the interior of the connecting cylinder 9, and the other end of the fixing screw 10 is fixedly installed with a handwheel 11.

[0028] When the settling device is connected to the surveying tripod, the bottom of the tripod legs is inserted into the connecting cylinder 9, and then the symmetrically arranged fixing screws 10 are screwed into the connecting cylinder 9 to press the tripod legs together for quick assembly. The handwheel 11 is designed to facilitate turning the fixing screws 10.

[0029] Please see Figure 1 The connecting assembly 1 includes a mounting plate base 101 and a side plate 102. The mounting plate base 101 is located below the connecting cylinder 9. There are two side plates 102, which are located on both sides of the connecting cylinder 9 respectively. The side plates 102 are rotatably connected to the connecting cylinder 9 via a rotating shaft. The lower end of the side plate 102 is fixedly connected to the mounting plate base 101.

[0030] The connecting component 1, through the mounting plate base 101, side plate 102 and the rotating shaft connecting to the connecting cylinder 9, realizes the flexible rotation between the tripod legs and the anti-settlement device, allowing the tripod legs to be freely adjusted according to the terrain conditions to adapt to the support requirements of different angles, so that the tripod can remain stable during the support process and increase its practicality.

[0031] Please see Figure 2The adjusting assembly 2 includes a mounting ring 201, an adjusting cylinder 202, and an adjusting screw 203. The mounting ring 201 is fixedly installed below the mounting plate base 101. The adjusting cylinder 202 is rotatably installed below the mounting ring 201. The adjusting screw 203 is located below the adjusting cylinder 202. The adjusting cylinder 202 has an internal thread. The upper end of the adjusting screw 203 extends into the interior of the adjusting cylinder 202 and is threadedly connected to the adjusting cylinder 202. The lower end of the adjusting screw 203 is fixedly connected to the anti-settlement plate 3.

[0032] The adjustment assembly 2 achieves height adjustment through the threaded connection design of the mounting ring 201, the adjustment cylinder 202 and the adjustment screw 203. It is convenient to adjust the height by rotating the adjustment cylinder 202 according to the unevenness of the ground, thereby ensuring that the measuring instrument is always in a horizontal state and increasing the flexibility of use.

[0033] Please see Figure 1 and Figure 4 A guide component 8 is provided on one side of the adjustment component 2. The guide component 8 includes a top block 801 and a guide plate 802. The upper end of the top block 801 is fixedly connected to the mounting plate base 101, and the lower end of the guide plate 802 is fixedly connected to the anti-settlement plate 3. An inner sliding groove is provided inside the top block 801, and the upper end of the guide plate 802 extends into the inner sliding groove of the top block 801. A scale line 8021 is provided on one end face of the guide plate 802.

[0034] The guide component 8 provides guidance through the sliding engagement of the top block 801 and the guide plate 802, preventing swaying during adjustment and ensuring the stability of height adjustment. The scale line 8021 provides an intuitive reference for height adjustment, allowing for precise control of the adjustment amount by observing the scale line on the guide plate, thus increasing practicality.

[0035] Working principle: When in use, insert the legs of the surveying tripod into the connecting cylinder 9, rotate the handwheels 11 on both sides to drive the fixing screw 10 to tighten the legs, and complete the quick assembly. The overall height of the device can be adjusted by rotating the adjusting cylinder 202 and driving the adjusting screw 203 through the threaded transmission. After the anti-settlement plate 3 contacts the ground, it serves as a support surface, increasing the contact area with the ground and preventing the legs from sinking. The three insert rods 4 are inserted into the soil to enhance the anchoring force. At the same time, the extension plate 5 is pulled out laterally to expand the support area, and the position of the stabilizing plate 6 is locked by the fixing bolt 7, thereby achieving uniform pressure distribution, improving the anti-settlement ability, and increasing practicality.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
