DETAILED DESCRIPTION

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0025] See also Figures 1 to 4 As shown, a total station support device includes a tripod 1 and a support assembly 2, wherein the tripod 1 includes a connecting plate 12 and three legs 11, the connecting plate 12 is used to receive the total station body 7, the three legs 11 are evenly arranged along the circumference of the connecting plate 12, and the top ends of the three legs 11 are respectively hinged to the outer edge of the connecting plate 12. When measurement is required, the staff adjusts the three legs 11 to open a certain angle to support the tripod 1 on the ground, and then fixes the total station body 7 on the top surface of the connecting plate 12, and then performs related measurement work.

[0026] There are three support assemblies 2, which are rotatably connected to the bottom end of each leg 11, and are used to support the tripod 1 to prevent the tripod 1 from being unstable or slipping on the ground, or even overturning during use. The support assembly 2 includes a hinge plate 21 and a support plate 22, the hinge plate 21 is rotatably connected to the bottom end of the leg 11, and the support plate 22 is fixedly arranged on the bottom surface of the hinge plate 21. That is, the support plate 22 is rotatably connected to the leg 11 by setting the hinge plate 21 to adapt to the uneven ground. In this embodiment, a threaded hole 221 is provided through the support plate 22, and the hinge plate 21 is fixedly connected to the threaded hole 221 of the support plate 22 by the first bolt 3, and the first bolt 3 is provided to realize the detachable connection between the hinge plate 21 and the support plate 22. Preferably, there are two threaded holes 221, and the two threaded holes 221 are respectively opened on both sides of the width direction of the support plate 22, so that the connection between the hinge plate 21 and the support plate 22 is more stable.

[0027] In this embodiment, the hinge plate 21 includes a bottom plate 211 and two side plates 212, wherein the two side plates 212 are fixedly arranged on the top surface of the bottom plate 211 at intervals, so that the cross section of the hinge plate 21 is slightly U-shaped. During implementation, the bottom end of the leg 11 is accommodated between the two side plates 212, that is, the bottom end of the leg 11 is accommodated inside the hinge plate 21 with a slightly U-shaped cross section, and a second bolt 4 is provided on one side of the hinge plate 21. The second bolt 4 passes through the side plate 212 on one side, the leg 11 and the side plate 212 on the other side in sequence, and is then screwed with a nut 41, thereby realizing the rotation connection between the hinge plate 21 and the leg 11.

[0028] In this embodiment, a conical portion 5 is fixedly provided on the top or bottom surface of the support plate 22, and the conical portion 5 is used to be inserted into a relatively soft ground (e.g., a dirt road) to better fix the tripod 1. The side of the support plate 22 away from the conical portion 5 is a plane, which is used to be placed on a relatively hard ground (e.g., a cement road). Preferably, a rubber pad 6 is fixedly provided on the side of the support plate 22 away from the conical portion 5 to prevent the support plate 22 from sliding against the ground. Furthermore, an anti-slip pattern 61 is provided on the side of the rubber pad 6 away from the support plate 22 to better fix the support plate 22.

[0029] In this embodiment, there are two conical parts 5, and the two conical parts 5 are respectively arranged on both sides of the length direction of the support plate 22. The conical part 5 includes a cone 51 and a fixing assembly 52. ​​The cone 51 is a cone with a hollow interior, and the tip of the cone 51 extends away from the support plate 22, and is used for plugging into the soft ground. The fixing assembly 52 includes a screw 521, a rotating ring 522 and a plurality of plug plates 523. One end of the screw 521 is screwed to the support plate 22, and the other end of the screw 521 passes through the support plate 22 and extends to the inside of the cone 51. The rotating ring 522 is sleeved on one end of the screw 521 located inside the cone 51 and is rotatably connected to the screw 521, that is, the rotating ring 522 can rotate along the central axis of the screw 521. Multiple plug plates 523 are evenly distributed on the outer edge of the rotating ring 522. There are four plug plates 523, and the four plug plates 523 are evenly arranged along the circumference of the rotating ring 522. One ends of the multiple plug plates 523 are respectively rotatably connected to the outer edge of the rotating ring 522. The free ends of the multiple plug plates 523 extend toward the direction close to the support plate 22. Multiple clearance openings 511 are opened on the outer side wall of the cone 51. The multiple plug plates 523 correspond to the multiple clearance openings 511 one by one, and the free end of each plug plate 523 is respectively inserted into the corresponding clearance opening 511.

[0030] During implementation, the staff rotates the first bolt 3 to separate the hinge plate 21 from the support plate 22, and makes the side of the support plate 22 with the rubber pad 6 contact the bottom plate 211. At this time, the conical portion 5 is set on the side away from the tripod 1, and then the hinge plate 21 and the support plate 22 are fixed by the first bolt 3. Then the staff steps on the support plate 22 to insert the conical portion 5 into the ground to fix the tripod 1 on the ground. At this time, the staff can rotate the screw rod 521 to move the screw rod 521 in the direction away from the cone 51 (here, since the rotating ring 522 is rotatably connected with the screw rod 521, and the multiple plug plates 523 are located in the corresponding clearance opening 511, the rotating ring 522 remains relatively still during the rotation of the screw rod 521). During the movement of the screw rod 521, the multiple plug plates 523 will move in the direction away from the central axis of the cone 51, so that the free ends of the multiple plug plates 523 pass through the clearance opening 511 and are plugged into the inside of the ground, thereby making the conical portion 5 more stably fixed to the ground.

[0031] When the utility model is implemented, the staff adjusts the three legs 11 to open a certain angle to support the tripod 1 on the ground, and fixes the total station body 7 on the top surface of the connecting plate 12, and then rotatably connects the hinge plate 21 to the bottom end of the leg 11 through the second bolt 4 and the nut 41, and selects the fixing direction of the support plate 22 according to the ground conditions (soft ground or harder ground).

[0032] When the tripod 1 needs to be supported on a harder ground, the side of the support plate 22 where the conical portion 5 is provided is fixedly connected to the bottom plate 211 of the hinge plate 21 by the first bolt 3, so that the side of the support plate 22 with the rubber pad 6 is in contact with the ground. The support plate 22 can increase the contact area between the tripod 1 and the ground, thereby increasing the stability of the tripod 1 and improving the measurement stability.

[0033] When you need to support the tripod 1 on soft ground, such as Figure 5 As shown, the staff uses the first bolt 3 to fix the side of the support plate 22 where the rubber pad 6 is provided to the bottom plate 211 of the hinge plate 21. At this time, the staff can step on the support plate 22 to insert the conical portion 5 into the ground to fix the tripod 1 on the ground. Then, the screw 521 is rotated to move the screw 521 away from the cone 51, thereby driving the multiple plug-in plates 523 to be inserted into the ground along the radial direction of the cone 5, thereby making the tripod 1 more stably fixed and preventing the tripod 1 from being unstable or slipping on the ground or even overturning during use. It should be noted that the end of the screw 521 away from the cone 51 is provided with a cross-shaped groove 5211 or a straight groove, and the staff can use a straight screwdriver or a cross screwdriver in the prior art to rotate the screw 521.

[0034] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
