[0030] The following further describes the present application in detail with reference to the attached Figures 1-4 drawings.

[0031] The embodiments of the present application disclose a positioning device for a surveying instrument.

[0032] Embodiment 1

[0033] Referring to Figure 1 and Figure 2, A positioning device for a surveying and mapping instrument includes a tripod body 1 and foot spikes 2. The foot spikes 2 are movably connected to the tripod body 1. The tripod body 1 is provided with a receiving cavity 11 for receiving the foot spikes 2. The tripod body 1 is provided with a positioning component 3 for fixing the foot spikes 2 to the tripod body 1 after the foot spikes 2 leave the receiving cavity 11. When carrying the positioning device, move the foot spikes 2 relative to the tripod body 1 and move the foot spikes 2 into the receiving cavity 11 for storage, so as to reduce the risk of the foot spikes 2 scratching the carrier and at the same time reduce the risk of damage to the foot spikes 2 due to collision; when it is necessary to install the positioning device, move the foot spikes 2 relative to the tripod body 1 to make the foot spikes 2 leave the receiving cavity 11, and then use the positioning component 3 to fix the foot spikes 2 to the tripod body 1.

[0034] In this embodiment, the specific connection structure between the foot spikes 2 and the tripod body 1 is as follows: An electric telescopic rod 12 is installed inside the tripod body 1. The output end of the electric telescopic rod 12 is connected to the foot spikes 2, and the electric telescopic rod 12 is used to drive the foot spikes 2 to move along the height direction of the tripod body 1. When it is necessary to store the foot spikes 2, use the electric telescopic rod 12 to drive the foot spikes 2 into the receiving cavity 11; when it is necessary to release the foot spikes 2, use the electric telescopic rod 12 to drive the foot spikes 2 to leave the receiving cavity 11. Thus, the electric telescopic rod 12 not only realizes the movable connection between the foot spikes 2 and the tripod body 1, but also plays a positioning role for the foot spikes 2. The structure is simple and easy to operate. It can be understood that in this embodiment, the electric telescopic rod 12 acts as a fixing component.

[0035] It can be understood that a plurality of foot spikes 2 are provided, and the plurality of foot spikes 2 are arranged at intervals around the central axis of the tripod body 1. Correspondingly, a plurality of receiving cavities 11 are provided, and the plurality of receiving cavities 11 correspond to the plurality of foot spikes 2 one by one.

[0036] In this embodiment, a plurality of electric telescopic rods 12 can be provided, and the plurality of electric telescopic rods 12 are connected to the plurality of foot spikes 2 one by one. The plurality of electric telescopic rods 12 respectively control the plurality of foot spikes 2 so that the positioning device is applicable to a variety of different installation environments.

[0037] In other embodiments, one electric telescopic rod 12 can also be provided. A plurality of connecting rods are connected to the output end of the electric telescopic rod 12, and the plurality of connecting rods are arranged corresponding to the plurality of foot spikes 2 one by one. The plurality of connecting rods are used to establish a connection between the plurality of foot spikes 2 and one electric telescopic rod 12 to achieve the effect of storing or releasing all the foot spikes 2 at one time.

[0038] Furthermore, a sealing member 21 is fixedly connected to the end of the foot peg 2 close to the electric telescopic rod 12, and the outer wall of the sealing member 21 is used to abut against the wall of the receiving cavity 11. Thus, after the foot peg 2 leaves the receiving cavity 11, the receiving cavity 11 is sealed by the sealing member 21, reducing the risk of foreign impurities entering the receiving cavity 11; in addition, after the foot peg 2 leaves the receiving cavity 11, an abutment is formed between the sealing member 21 and the wall of the receiving cavity 11, reducing the risk of the foot peg 2 shaking relative to the tripod body 1 and improving the installation stability of the positioning device.

[0039] Furthermore, a connecting member 4 is provided between the foot peg 2 and the electric telescopic rod 12. A sliding cavity 22 is formed in the sealing member 21 along its length direction, and the end of the sliding cavity 22 penetrates through the end face of the sealing member 21 close to the electric telescopic rod 12. One end of the connecting member 4 is connected to the bottom of the receiving cavity 11, and the other end passes through the sliding cavity 22 and fits with the wall of the sliding cavity 22. With this design, on the one hand, the sealing member 21 is lightened by forming the sliding cavity 22 in the sealing member 21; on the other hand, after the foot peg 2 leaves the receiving cavity 11, the sealing member 21 is clamped by the wall of the receiving cavity 11 and the outer wall of the connecting member 4, further reducing the risk of the foot peg 2 shaking relative to the tripod body 1 and improving the installation stability of the positioning device.

[0040] The implementation principle of Embodiment 1 is as follows: When transporting the positioning device, the electric telescopic rod 12 is activated, and the foot peg 2 is driven by the electric telescopic rod 12 to enter the receiving cavity 11 for storage, so as to reduce the risk of the foot peg 2 scratching the handlers and also reduce the risk of the foot peg 2 being damaged.

[0041] When installing the positioning device, the electric telescopic rod 12 is activated, and the foot peg 2 is driven by the electric telescopic rod 12 to move out of the receiving cavity 11. The structure is simple and easy to operate.

[0042] Embodiment 2

[0043] Referring to Figure 3 and Figure 4 , the difference between this embodiment and Embodiment 1 is that the foot peg 2 is hinged to the tripod body 1. When storing and releasing the foot peg 2, the foot peg 2 is rotated relative to the tripod body 1.

[0044] In this embodiment, the end face of the foot peg 2 away from its tip is arc-shaped, so as to facilitate guiding when the foot peg 2 is rotated and ensure the smoothness of the rotation of the foot peg 2 relative to the tripod body 1.

[0045] In this embodiment, the positioning assembly 3 includes a screw 31 and a threaded sleeve 32. The threaded sleeve 32 is embedded inside the foot peg 2, the screw 31 is threadedly connected to the tripod body 1, and the screw 31 is in threaded cooperation with the threaded sleeve 32. When releasing the foot peg 2, first rotate the foot peg 2 relative to the tripod body 1, and then turn the screw 31 to relatively fix the foot peg 2 and the tripod body 1 with the screw 31.

[0046] It can be understood that in this embodiment, the side wall of the foot nail 2 abuts against the cavity wall of the accommodating cavity 11, and the friction between the foot nail 2 and the cavity wall of the accommodating cavity 11 is utilized to make the foot nail 2 snap into the accommodating cavity 11, thereby reducing the risk of the foot nail 2 coming out of the accommodating cavity 11 during handling.

[0047] Furthermore, a magnet (not marked in the figure) is provided at the bottom of the accommodating cavity 11, the foot nail 2 is made of a magnetic material, and the screw 31 is made of a magnetic material. With this design, on the one hand, the magnetic attraction between the magnet and the foot nail 2 is utilized to enhance the installation stability of the foot nail 2 in the accommodating cavity 11; on the other hand, when handling the positioning device, the screw 31 can also be removed and magnetically attracted into the accommodating cavity 11, so that the screw 31 does not protrude from the tripod body 1, reducing the risk of the screw 31 scratching the handling personnel and also reducing the risk of the screw 31 being lost.

[0048] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
