Description

Technical Field

[0001] This utility model relates to the field of surveying instrument accessories technology, specifically to a total station support device with good stability. Background Technology

[0002] A total station is a high-precision measuring instrument that requires a high degree of stability in its support system during operation. Existing total station tripods typically have a simple leg structure with a simple metal tip at the end, which makes them suitable for use on the ground in the field, but difficult to adapt to diverse working surfaces.

[0003] When working on smooth indoor tile or marble floors, the metal-tipped feet are prone to slipping, causing the instrument to shift. When working outdoors on sand or mud, the feet are prone to sinking, causing the instrument to tilt. Both of these situations will seriously affect the accuracy of the measurement data.

[0004] Therefore, a total station support device that can adapt to various complex ground conditions and maintain high stability is needed. Utility Model Content

[0005] In order to overcome the problems in the background technology, this utility model provides a total station support device with good stability, which solves the technical problem that the tripod support structure in the traditional technology is simple and cannot adapt to various ground conditions.

[0006] A stable total station support device includes a total station base, support legs, and a foot assembly. At least three support legs are evenly hinged to the bottom of the total station base. Adjustable telescopic tube sections are provided on the support legs. The foot assembly is hinged to the end of the support legs via a pivot and contacts the ground. The foot assembly includes a U-shaped plate and a counterweight. One end of the U-shaped plate is hinged to the end of the support leg, and the counterweight is integrally formed with the U-shaped plate and connected between the U-shaped plates.

[0007] Furthermore, the support leg assembly also includes an adjustment block, which has an inverted T-shaped structure. The connecting block at the lower end of the adjustment block is covered with a rubber layer. The lower end of the adjustment block is fitted into a slot opened at the bottom of the U-shaped plate, and the connecting block at the upper end of the adjustment block is installed into an adjustment hole opened on the counterweight block.

[0008] Furthermore, the rubber layer at the bottom of the connecting block at the lower end of the adjusting block is provided with a wave pattern.

[0009] Furthermore, the end of the U-shaped plate that is hinged to the support leg assembly is integrally formed with a sharp spike. Furthermore, the pivot axis connecting the support leg assembly to the support leg is a damping pivot axis or a limiting pivot axis.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This utility model's support assembly integrates four functional modes—large-area support, high-friction support, negative pressure adsorption support, and ground spike support—in a single component. Its compact structure and strong applicability are key features. The base, composed of a U-shaped plate and a counterweight, increases the contact area with the ground and adds weight, effectively preventing sinking on soft surfaces such as sand and mud, thus greatly improving stability. The bottom of the adjusting block features a textured rubber layer to provide friction, suitable for smooth ceramic or marble surfaces, effectively preventing instrument slippage. The integrated ground spike at the tail of the U-shaped plate allows for secure fixation in outdoor environments such as grass and soil by rotating the support assembly. On extremely smooth surfaces (such as glass), the adjustment block and slot work together to extract air from the cavity formed between the bottom of the U-shaped plate and the ground, creating negative pressure adsorption for a firm fixation.

Detailed Implementation

[0014] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0015] See Figure 1 , Figure 2A total station support device with good stability includes a total station base 1, at least three support legs 2, and support leg assemblies 3 respectively installed at the ends of the support legs 2; the total station base 1 is used to install the total station body, the support legs 2 are evenly hinged to the bottom of the total station base 1, and each support leg 2 is provided with an adjustable telescopic tube section 21 for adjusting the overall height of the support device and adapting to uneven ground; See Figure 3 , Figure 4 , Figure 5 The foot assembly 3 is hinged to the end of the support leg 2 via a pivot; preferably, the pivot is a damping pivot or a limiting pivot, so that the foot assembly 3 can stably stay at the required angle in the rotation adjustment mode and will not sway randomly. See Figure 5 The support leg assembly 3 includes a U-shaped plate 31 and a counterweight 32. The U-shaped plate 31 and the counterweight 32 are preferably integrally formed, forming a wide base of the support leg assembly 3, which increases the contact area. When working on soft ground (such as sand or mud), the wide base provides a larger support area to prevent the support leg 2 from sinking. At the same time, the counterweight 32 increases the weight of the support leg, further lowers the center of gravity of the device, and improves the overall wind resistance and vibration resistance stability. See Figure 5 The support leg assembly 3 also includes a detachable adjustment block 33. The counterweight block 32 has an adjustment hole 321, and the bottom of the U-shaped plate 31 has a slot 311. The adjustment block 33 has an inverted T-shaped structure, with a connecting block at the bottom. The bottom surface of the connecting block, which is in contact with the ground, is covered with a rubber layer 331. The upper part of the adjustment block 33 forms a handle for easy insertion and removal. In use, the lower connecting block of the adjustment block 33 is inserted into the slot 311 so that the rubber layer 331 faces the ground. The bottom surface of the rubber layer 331 is provided with a wave pattern 332. When working on smooth marble or tile floors, the rubber layer 331 with the wave pattern 332 can provide great friction and prevent the support leg from slipping. This utility model can also realize a negative pressure stabilization mode. The slot 311 is a through hole that penetrates the bottom of the U-shaped plate 31. When working on an extremely smooth surface such as glass, the adjusting block 33 is inserted into the slot (311, 321). Its rubber layer 331 forms a seal with the inner wall of the slot, and the bottom surface of the U-shaped plate 31 is flat against the surface, so that a sealed cavity is formed between it and the surface. At this time, by holding the upper handle of the adjusting block 33 and pulling it upward, the adjusting block 33 acts like a piston to draw air from the sealed cavity, forming a negative pressure in the cavity, so that the entire support assembly 3 is firmly attached to the smooth surface. Please see Figure 5 , Figure 6At the end of the U-shaped plate 31 that is hinged to the support leg 2, a sharp spike 34 is integrally formed. When working on grass or soil in the field, the entire support leg assembly 3 can be rotated upward around its axis of rotation with the support leg 2 so that the spike 34 faces downward. Stepping on it will insert the spike 34 into the ground and achieve a firm fixation.

[0016] Work process: Increased contact area for stability: On soft ground, the wide bottom surface of the support leg assembly 3 directly contacts the ground to form a stable support mode; Increase frictional stability: On a smooth surface, insert the adjusting block 33 into the slot 311, and use the rubber layer 331 with wave pattern 332 to contact the ground to form a stable support mode; Spike stabilization: On the ground in the field, flip the support component 3 and insert the spike 34 into the ground to form a stable support mode; Negative pressure stabilization: On an extremely smooth surface, insert the adjusting block 33 and place the U-shaped plate 31 flat on the ground. Then lift it up to use the negative pressure generated to adsorb and fix it, forming a stable support mode.

[0017] By switching between these four modes, this device can adapt to provide stable support under different working conditions.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
