Description

Technical Field

[0001] This utility model relates to the field of engineering surveying equipment technology, and in particular to a tripod anti-slip device. Background Technology

[0002] In engineering settlement measurement, tripods are key equipment for supporting measuring instruments (such as levels, total stations, and 3D laser scanners). Traditional tripods have metal pointed ends at the ends, which are prone to wear and tear from friction with the ground during daily use, greatly affecting the service life of the tripod. When working on wet and slippery ground, the tripod is prone to sliding, leading to measurement errors or even data loss. When working on sloping roads, the tripod is prone to tipping over, causing damage to the instrument and unnecessary losses. Anti-slip devices are usually used to fix the tripod.

[0003] However, most existing anti-slip devices are fixed designs. Once fixed to the tripod, the anti-slip device is inconvenient to disassemble and cannot be used for operations such as leveling that require frequent changes in tripod position. Furthermore, it cannot adapt to different terrains and tripod sizes. Utility Model Content

[0004] The purpose of this utility model is to provide a tripod anti-slip device that can be quickly disassembled, has excellent anti-slip performance, and is compatible with various models.

[0005] In this utility model, the tripod anti-slip device includes: a U-shaped slot assembly, a bidirectional folding mechanism, and an anti-slip body. The bidirectional folding mechanism includes an upper arm and a lower arm, which are connected by a telescopic adjustment rod. One end of the U-shaped slot assembly is provided with a U-shaped groove, and the other end is connected to the upper arm through a first damping pivot. One end of the anti-slip body is provided with a groove that matches the end of the tripod, and the other end is connected to the lower arm through a second damping pivot.

[0006] In addition, the first and second damping shafts have angle adjustment and locking functions, with an angle adjustment range of ±90°.

[0007] In addition, the telescopic adjustment rod has a double-sleeve structure, and the telescopic length is locked by threads or buckles, with a telescopic length range of 50-150mm.

[0008] In addition, the groove is an inverted cone shape with an elastic inner wall and a depth of 3-5cm.

[0009] In addition, the bottom of the anti-slip body is also equipped with protrusions.

[0010] In addition, the height of the protrusions is 0.5-1cm, and the spacing between each protrusion is 1-2cm.

[0011] In addition, the inner wall of the U-shaped groove is provided with elastic anti-slip texture.

[0012] In this embodiment of the invention, a detachable bidirectional folding mechanism connects the U-shaped slot assembly and the anti-slip body, providing a wide range of angle adjustment to accommodate more tripod unfolding angles. The telescopic adjustment rod allows for height difference compensation, solving the tilting problem caused by uneven legs. The U-shaped slot and groove are connected by clamping the tripod with an elastic inner wall, allowing for tool-free installation and disassembly, adapting to different working environments and tripod models. The protrusions on the rubber anti-slip body enhance anti-slip stability and extend service life. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments. The division of the various embodiments below is for ease of description and should not constitute any limitation on the specific implementation of this utility model. The various embodiments can be combined with and referenced by each other without contradiction.

[0018] One embodiment of this utility model relates to a tripod anti-slip device, which is installed at the tail end of each support of the tripod, as shown in the specific installation position. Figure 1 As shown in the diagram. In this embodiment, the structural schematic diagram of the tripod anti-slip device is as follows. Figure 2 As shown, it includes: a U-shaped slot assembly 1, a bidirectional folding mechanism, and an anti-slip body 5. The bidirectional folding mechanism includes an upper arm 2 and a lower arm 4, which are connected by a telescopic adjustment rod 3. One end of the U-shaped slot assembly 1 is provided with a U-shaped groove, and the other end is connected to the upper arm 2 through a first damping pivot. One end of the anti-slip body 5 is provided with a groove 6 that matches the end of the tripod, and the other end is connected to the lower arm 4 through a second damping pivot.

[0019] In one example, the first and second damping pivots have angle adjustment and locking functions, with an angle adjustment range of ±90°. The tripod anti-slip device can be adapted to tripods with an unfolding angle between 30° and 75° by adjusting the damping pivots. The telescopic adjustment rod 3 is a double-section sleeve structure, and the telescopic length is locked by threads or buckles. The telescopic length range is 50-150mm, which can adjust the vertical height of the tripod anti-slip device to compensate for the height difference between different tripod legs.

[0020] In one example, the anti-slip body 5 is made of high-friction rubber with a Shore A hardness of 60-80. This allows the anti-slip body 5 to combine wear resistance with elastic deformation capability, increasing the service life of the tripod anti-slip device. Furthermore, the U-shaped slot assembly 1, made of high-strength nylon, also contributes to the service life of the tripod anti-slip device. The bottom of the anti-slip body 5 also features protrusions 7, such as... Figure 3 As shown, the height of the protrusion 7 is 0.5-1cm, and the multiple protrusions 7 are arranged in a matrix with a spacing of 1-2cm between each protrusion 7. By setting the protrusions, a better anti-slip effect can be achieved, and combined with the high friction coefficient of the rubber material, a dual anti-slip function is realized.

[0021] In one example, groove 6 is an inverted cone shape with an elastic inner wall and a depth of 3-5 cm.

[0022] In one example, the inner wall of the U-shaped groove is provided with elastic anti-slip texture. When in use, the U-shaped groove is used to pass through the tripod legs, and the tripod legs are clamped in the groove by the elastic anti-slip texture to achieve fixation. When in use, the metal tip of the tripod is inserted into the groove 6 and clamped by the elastic structure of the inner wall to achieve fixation. The U-shaped slot assembly 1 and the groove 6 fix the tripod and the tripod anti-slip device by clamping with the elastic structure, which can make the tripod anti-slip device suitable for more different types of tripods. In this embodiment, the tripod anti-slip device is suitable for tripods with a tripod leg diameter or width of 10-30mm.

[0023] In one example, the damping shaft is made of stainless steel and coated with an anti-corrosion layer to improve corrosion resistance. The U-shaped slot assembly 1, the bidirectional folding mechanism, and the anti-slip body 5 are all connected by the damping shaft, forming a modular and detachable structure that is easy to disassemble and move.

[0024] In one embodiment, the installation steps of the tripod anti-slip device and the tripod include: snapping the U-shaped groove of the U-shaped slot assembly 1 into the tail of the tripod, turning the bidirectional folding mechanism to make the anti-slip body 5 parallel to the ground, maintaining the set angle through the damping pivot, stretching the telescopic adjustment rod 3 to an appropriate length, pressing down the tripod to make the metal tip embedded in the groove 6, and finally making the bottom protrusion 7 fully contact the ground.

[0025] After installation, tests showed that on smooth surfaces, the bottom protrusion 7 of the tripod anti-slip device did not slip after contacting the ground. When a 50kg load was applied on a 15° slope, the displacement of the tripod anti-slip device was <1mm, which is significantly better than the ≥5mm displacement of traditional structures. When the ground was uneven, the rubber material deformed and adhered to the ground, still achieving high stability.

[0026] When the tripod anti-slip device needs to be disassembled for maintenance, simply remove the U-shaped slot assembly 1 to remove the tripod anti-slip device, clean it, and reuse it.

[0027] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
