[0021] like Figure 1-4As shown, the utility model proposes an anti-skid device for a measuring tripod, comprising a base 1 and a support cone 2 and a telescopic rod 3 respectively hinged at two ends of the top of the base 1, the movable end of the telescopic rod 3 is hinged to the side wall of the movable end of the support cone 2, the bottom surface of the base 1 is connected with an anti-skid pad 4, and the movable end of the support cone 2 is coaxially provided with a conical accommodating hole.
[0022] Connecting ear plates are provided in pairs at both ends of the top of the base 1, and the support cone 2 and the telescopic rod 3 are hinged by connecting the ear plates and the rotating shaft 201, and the movable end of the telescopic rod 3 is rotatably connected to the outer wall of the movable end of the support cone 2 by connecting the ear plates and the rotating shaft 201. When the measuring tripod is used on a smooth surface, the tripod legs are inserted into the conical holes in the support cone 2, and then the steps of centering and leveling are performed, and the tripod and the anti-skid device are adjusted to the appropriate position so that the top of the tripod is level, and then the station work is completed. After the measurement is completed, when it is necessary to move to another site, the protective device can be pulled out and stored separately.
[0023] like Figure 2 and Figure 5 The telescopic rod 3 comprises a sleeve 302 and an insertion rod 301 axially slidably connected in the sleeve 302. The movable ends of the sleeve 302 and the insertion rod 301 are respectively hinged on the base 1 and the support cone 2. A spring 303 is installed in the sleeve 302. The two ends of the spring 303 are respectively fixedly connected to the movable ends of the sleeve 302 and the insertion rod 301.
[0024] When the tripod is installed, the tripod will press down the insertion rod 301 due to gravity, and then press down the spring 303, and use the spring 303 to press down the sleeve 302 and the base 1, so that the downward force of the tripod is decomposed into force on the support cone 2 and the sleeve 302, and then the force is decomposed to the two ends of the base 1, further improving the stability of the base 1 and the anti-slip effect of the anti-slip device.
[0025] As a preferred embodiment of the present invention, in order to prevent the insertion rod 301 from coming out of the sleeve 302, a limiting protrusion is arranged in the movable port of the sleeve 302, the inner diameter of the limiting protrusion is equal to the outer wall of the insertion rod 301, a protrusion is arranged in the middle of the outer peripheral surface of the insertion rod 301, and one end of the spring 303 is sleeved on the insertion rod 301. In addition, the cooperation between the protrusion and the limiting protrusion can ensure that a section of the insertion rod 301 is always located in the sleeve 302, ensure the stability of the axial movement of the insertion rod 301, and at the same time ensure the stability of the connection end between the spring 303 and the insertion rod 301.
[0026] like Figure 3As shown, in order to enhance the anti-skid performance of the anti-skid pad 4, the bottom of the anti-skid pad 4 is evenly provided with tooth grooves 401, and the opening of the tooth grooves 401 is in a regular hexagon. The anti-skid pad 4 is generally made of rubber or a fabric material with a rubber back, and the bottom surface of the anti-skid pad 4 is provided with a plurality of groups of hexagonal tooth grooves 401, so that the surface edge of the anti-skid pad 4 is rough, thereby increasing the friction of the anti-skid pad 4 when contacting the surface of some objects.
[0027] like Figure 4 and Figure 5 As shown. The top of the side wall of the anti-skid pad 4 is provided with an annular protrusion, the bottom of the base 1 is provided with a receiving groove for accommodating the anti-skid pad 4, and the top of the inner side wall of the receiving groove is provided with a slot 101 adapted to the annular protrusion. The anti-skid pad 4 is connected to the inside of the base 1 by mortise and tenon joints, and is easy to disassemble and replace when the anti-skid pad 4 is worn out after long-term use.
[0028] like Figure 1 As shown, in order to avoid being cut by the anti-slip device when storing, the top of the base 1 and the movable end of the support cone 2 are both provided with chamfers.
