Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A surveying and mapping device, referring to fig. 1, comprises a mounting base 1, a surveying and mapping instrument 2 fixedly mounted on the mounting base 1, and a supporting frame (not labeled in the figure) arranged below the mounting base 1 and used for supporting the mounting base 1; the top end of the supporting frame is provided with a fixing plate 4 in a circular ring shape.

Specifically, the support frame comprises three support legs 3 which are uniformly distributed around the circumference of a fixed plate 4, the upper ends of the support legs 3 are hinged to the edge of the fixed plate 4, and the support legs 3 can incline towards the direction outside the fixed plate 4; the leg 3 forms an angle in the range of 0-25 with a line perpendicular to the fixing plate 4. After the surveying and mapping device is used, the supporting legs 3 can be rotated back to be folded, so that the occupied space of the surveying and mapping device is reduced, and the surveying and mapping device is convenient to store and carry. Landing leg 3 is when opening, and the angle of turning round is 25, even makes landing leg 3 can the stable stay to fixed plate 4 and mount pad 1, also when surveying instrument 2 is in a take the altitude, the length of required landing leg 3 is comparatively suitable, further reduces the shared space of landing leg 3 to the preparation material of landing leg 3 is practiced thrift.

Specifically, the leg 3 includes an upper rod 31 connected to the fixing plate 4 and a lower rod 32 connected to the upper rod 31, the cross sections of the upper rod 31 and the lower rod 32 are rectangular, and one side of the lower end surface of the upper rod 31 is hinged to one side of the upper end surface of the lower rod 32. When the lower end surface of the upper rod 31 abuts against the upper end surface of the lower rod 32, the supporting legs 3 are completely opened, and the hinged ends of the upper rod 31 and the lower rod 32 are located on the inner sides of the supporting legs 3 facing the axis of the fixing plate 4, so that the lower rod 32 is stably supported on the ground, the lower rod 32 and the upper rod 31 are not easy to bend, and the supporting legs 3 more stably support the fixing plate 4 and the mounting seat 1. In addition, after the surveying and mapping device is used, the upper rod 31 and the lower rod 32 are folded and retracted, so that the length of the retracted support legs 3 is smaller, and the surveying and mapping device is further convenient to store and carry.

Referring to fig. 1 and 2, the fixing plate 4 is provided with a through hole 5 penetrating through the upper and lower surfaces of the fixing plate 4 along the vertical direction, the through hole 5 is in sliding fit and penetrates through a rectangular strip-shaped mounting bar 6, and the top of the mounting bar 6 is fixedly connected to the lower surface of the mounting base 1.

Referring to fig. 2 and 3, a rack 7 is fixedly mounted on one side wall of the mounting bar 6 along the length direction of the mounting bar 6, a gear 8 meshed with the rack 7 is rotatably carried on the lower surface of the fixing plate 4 along the horizontal direction, and a locking structure for realizing or limiting the rotation of the gear 8 is connected to the gear 8. When surveying not co-altitude, staff passes through rotating gear 8 at needs lift surveying appearance 2, and then makes and takes place to remove from top to bottom with rack 7 of gear 8 engaged with, has realized the regulation of surveying appearance 2 height, and rack 7 is fixed after adjusting suitable height under the effect of locking structure simultaneously, and simple structure is practical.

In this embodiment, a lateral wall of mounting bar 6 is provided with the bar groove 61 that is used for holding rack 7, and in rack 7 was fixed in bar groove 61, one side that bar groove 61 tank bottom was kept away from to rack 7 was leveled mutually with the lateral wall of mounting bar 6, and such setting has improved the holistic roughness of mounting bar 6 for 2 regulation effects of surveying instrument are better.
