[0002] The auxiliary support tripod for a total station used in building inspection is a key piece of equipment that provides a stable and accurate measurement reference for the total station. Its adjustable leg structure adapts to different ground conditions, ensuring the accuracy of measurement data. Currently, the base of this tripod often uses a leg structure composed of universal joints and foot pads to enhance adaptability and stability on soft or uneven ground.

[0003] However, in existing designs, the universal joint adjustment mechanism is typically exposed to the external environment. In construction testing sites where harsh conditions such as sandstorms and mud are common, dust can easily penetrate and adhere to the adjustment gaps and moving parts of the universal joint, leading to increased rotational resistance, adjustment failure, and even accelerated wear. This severely affects the stability and service life of the tripod and poses a potential risk to measurement accuracy. Utility Model Content

[0004] Therefore, it is necessary to provide an auxiliary support device for building inspection to address the problem that the universal joint adjustment mechanism of existing total station tripods is susceptible to adjustment failure and wear due to the exposed design of the mechanism, which is easily affected by dust intrusion on site, thus affecting the stability and accuracy of measurement.

[0005] An auxiliary support device for building inspection, comprising:

[0006] A triangular bracket, wherein each of the three triangles of the triangular bracket is fixedly connected to a telescopic support leg, and the bottom of the telescopic support leg is provided with a threaded mounting groove.

[0007] The system comprises three stabilizing support mechanisms, each including a universal joint threaded into the inner side of a threaded mounting groove. A foot pad is fixedly connected to the bottom of the universal joint, and a rubber bellows is fixedly connected to the top of the foot pad. A sealing cover plate, which is fixedly connected to the universal joint, is fixedly connected to the top of the rubber bellows. The adjustment part of the universal joint is located inside the rubber bellows.

[0008] In one embodiment, the universal joint includes a threaded post threadedly connected to the inner side of the threaded mounting groove. The bottom of the threaded post is fixedly connected to the inner side of the sealing cover plate. An adjusting ball is fixedly connected to the bottom of the threaded post. An adjusting seat fixedly connected to the foot pad is sleeved on the surface of the adjusting ball. Both the adjusting ball and the adjusting seat are located inside the rubber bellows.

[0009] In one embodiment, the surfaces of the threaded column and the adjusting ball are provided with interconnected adjusting cavities. The inner side of the lower adjusting cavity is slidably connected to a threaded tube that contacts the adjusting seat. The cross-sectional shape of the contact part between the lower adjusting cavity and the threaded tube is a matching rectangle. The inner side of the threaded tube is threadedly connected to a smooth bolt that is rotatably connected to the upper adjusting cavity. The surface of the smooth bolt is fixedly connected to a lever that is slidably connected to the upper adjusting cavity.

[0010] In one embodiment, a first adjusting block is rotatably connected to the surface of the threaded column, and one end of the lever is fixedly connected to the first adjusting block.

[0011] In one embodiment, a second adjusting block is fixedly connected to the surface of the threaded post, and the second adjusting block is disposed above the first adjusting block.

[0012] In one embodiment, the cross-sectional shape of the first adjusting block and the second adjusting block perpendicular to the axis of the threaded column is a regular hexagon.

[0013] In one embodiment, a friction-enhancing pad is fixedly connected to the bottom of the foot pad, and the friction-enhancing pad is a fluororubber material component.

[0014] In one embodiment, the bottom of the resistance-enhancing pad is provided with a resistance-enhancing groove, and the resistance-enhancing groove is in the shape of a grid.

[0015] Beneficial effects

[0016] 1. The aforementioned auxiliary support device for building inspection forms a fully enclosed flexible protective cover through rubber corrugated pipes and sealing cover plates, sealing the adjustment parts of the universal joint inside, effectively isolating the intrusion of dust and mud pollutants at the construction site, ensuring the long-term sensitivity and reliability of the adjustment mechanism, and greatly extending the service life of the equipment.

[0017] 2.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The following is combined with Figure 1 - Figure 5 This utility model describes an auxiliary support device for building inspection.

[0028] In one embodiment, an auxiliary support device for building inspection includes: a triangular bracket 100 and three stabilizing support mechanisms 300. Each of the triangular brackets 100 is fixedly connected to a telescopic leg 200, and the bottom of the telescopic leg 200 has a threaded mounting groove 210. The triangular bracket 100 is typically made of aluminum alloy or carbon fiber composite material and has a standard metric threaded instrument connection platform at its center for tightening and securing a total station. Each telescopic leg 200 consists of multiple tubular sleeves, typically three sections with decreasing diameters, using a lever-type or knob-type locking mechanism for rapid extension and length locking. The bottom of the last section of the leg has a threaded mounting groove 210, which is used for standardized connection to the stabilizing support mechanism 300.

[0029] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the stabilizing support mechanism 300 includes a universal joint 310 threadedly connected to the inner side of the threaded mounting groove 210. This connection method enables the modularity and replaceability of the stabilizing support mechanism 300. A foot pad 320 is fixedly connected to the bottom of the universal joint 310, and a rubber bellows 330 is fixedly connected to the top of the foot pad 320. A sealing cover plate 340, which is fixedly connected to the universal joint 310, is fixedly connected to the top of the rubber bellows 330. The adjusting part of the universal joint 310 is located inside the rubber bellows 330, thus forming a fully enclosed, retractable, flexible protective cover. This completely isolates dust, mud, and other pollutants from the construction site, ensuring the long-term sensitivity and reliability of the core adjusting part and greatly extending the equipment's lifespan. The bottom of the foot pad 320 is fixedly connected to a friction-enhancing pad 350, which is a fluororubber component. This material has excellent wear resistance, oil resistance and a high coefficient of friction, providing strong grip and anti-slip performance on a variety of surfaces. The bottom of the friction-enhancing pad 350 has a friction-enhancing groove 351, which is grid-shaped. This design can further increase the contact area and engagement effect with the ground, prevent sinking on soft ground, increase friction on smooth ground, and enhance the overall stability of the support in all aspects.

[0030] like Figure 3 , Figure 4 and Figure 5As shown, the universal joint 310 includes a threaded post 311 threadedly connected to the inner side of the threaded mounting groove 210. The bottom of the threaded post 311 is fixedly connected to the inner side of the sealing cover plate 340. An adjusting ball 312 is fixedly connected to the bottom of the threaded post 311. An adjusting seat 313, which is fixedly connected to the foot pad 320, is fitted on the surface of the adjusting ball 312. This ball-and-socket joint enables the foot pad 320 to self-adapt to multiple angles in any direction, allowing the device to perfectly adapt to various uneven test surfaces. The adjusting ball 312 and the adjusting seat 313 are both located inside the rubber bellows 330. The surfaces of the threaded post 311 and the adjusting ball 312 are each provided with an interconnected adjusting cavity 314. A threaded tube 315 that contacts the adjusting seat 313 is slidably connected to the inner side of the lower adjusting cavity 314. The cross-sectional shape of the contact area between the lower adjusting cavity 314 and the threaded tube 315 is a matching rectangle. This design effectively prevents the threaded tube 315 from rotating. The inner thread of the threaded tube 315 is connected to a smooth bolt 316 that is rotatably connected to the upper adjusting cavity 314. The surface of the smooth bolt 316 is fixedly connected to a lever 317 that is slidably connected to the upper adjusting cavity 314, thus forming a reliable threaded transmission locking mechanism. The surface of the threaded column 311 is rotatably connected to a first adjusting block 318. One end of the lever 317 is fixedly connected to the first adjusting block 318, so that turning the first adjusting block 318 can drive the entire locking mechanism. The surface of the threaded column 311 is fixedly connected to a second adjusting block 319, which is located above the first adjusting block 318. This double adjusting block design facilitates the application of reaction force during operation, achieving quick and effortless fine leveling. The cross-sectional shape of the first adjusting block 318 and the second adjusting block 319 perpendicular to the axis of the threaded column 311 is a regular hexagon, which conforms to ergonomics and is easy to operate with a general-purpose wrench.

[0031] The specific operating procedure for this auxiliary support device used in building inspection is as follows:

[0032] Unfolding and coarse leveling: Hold the center hub of the tripod 100 and unfold the three telescopic legs 200 outward to their natural limit positions. Roughly estimate the required leg length based on the terrain. Loosen the locking mechanism of each leg in sequence, pull it out to the appropriate length, and then immediately lock it. The initial coarse leveling of the instrument is achieved by changing the length difference of the three legs.

[0033] Connecting and deploying the stabilizing support mechanism 300: Screw the threaded post 311 of the universal joint 310 at the upper end of the stabilizing support mechanism 300 into the threaded mounting groove 210 at the bottom of the telescopic outrigger 200, and tighten to ensure a secure connection.

[0034] Fine leveling and stabilization: Place the device at the measurement point. By stepping on or pressing, ensure that the friction-enhancing pads 350 under each foot pad 320 make full contact with the ground and embed themselves, utilizing the properties of the mesh-like friction-enhancing grooves 351 and fluororubber material to provide maximum friction.

[0035] If the ground is uneven, use tools or manually turn the first adjusting block 318 in the corresponding direction. Through the mechanical transmission of the internal smooth rod bolt 316 and threaded tube 315, the threaded tube 315 is driven to separate from the adjusting seat 313, so that the adjusting ball 312 can rotate freely inside the adjusting seat 313, thereby finely adjusting the final support angle of the outrigger and achieving precise leveling. After the leveling operation is completed, turn the first adjusting block 318 in the opposite direction so that the threaded tube 315 and the adjusting seat 313 come into contact together, locking the adjusting ball 312 inside the adjusting seat 313.

[0036] Total station installation and final adjustment: Screw the total station firmly into the instrument connection platform at the top of the tripod 100 through the center thread of its base. Observe the electronic bubble on the total station and fine-tune the length of the three telescopic legs 200 or adjust the angle of the universal joint 310 until the instrument is completely level.

[0037] Dust protection: Throughout the entire use process, the rubber bellows 330 always completely encloses the core adjustment parts of the universal joint 310, namely the adjusting ball 312 and the adjusting seat 313, forming a flexible sealed chamber that effectively isolates dust, mud and other pollutants at the construction site, ensuring that the adjustment mechanism is reliable and maintenance-free for a long time.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
