[0005] In response to the shortcomings of the existing technology, the purpose of the present utility model is to provide a building surveying and mapping device. When positioning, the telescopic positioning rod and the positioning pin are kept in a vertical state, and the positioning pin is pointed to the positioning point. Then, the height of the support rod is manually adjusted so that the center rod and the telescopic positioning rod are kept in the same straight line, thereby completing the positioning of the surveying head.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a building surveying and mapping device, including a bracket and a surveying head, the bracket including a base body, the lower end of the base body is fixedly connected to a center rod, the center rod is hinged with three support rods, the support rods are hinged with connecting rods, the other ends of several connecting rods are hinged with a sliding ring, the sliding ring is sleeved on the center rod, the lower end of the center rod is rotatably connected to a telescopic positioning rod, the lower end of the telescopic positioning rod is rotatably connected to a positioning pin, the telescopic positioning rod is provided with a receiving groove, and the positioning pin can be received in the receiving groove.

[0007] By adopting the above technical solution, when people unfold the bracket, they move the three support rods away from the center rod by hand, and the connecting rod drives the sliding ring to slide downward until the connecting rod and the center rod are in a vertical state. The positioning pin is turned out from the receiving groove by hand so that the positioning pin and the telescopic positioning rod are on the same straight line and point to the positioning point. Then, the height of the support rod is manually adjusted so that the center rod and the telescopic positioning rod are kept on the same straight line, thereby completing the positioning of the surveying head. The setting of the connecting rod improves the stability of the bracket, and the receiving groove is used to store the positioning pins to prevent the positioning pins from being bumped when the building surveying and mapping device is not in use.

[0008] The utility model is further configured as follows: the lower end of the central rod is fixedly connected to a bearing seat, the bearing seat is rotatably connected to a hinged member, and the hinged member is hinged to the telescopic positioning rod.

[0009] By adopting the above technical solution, the telescopic positioning rod is rotated by hand, and the telescopic positioning rod drives the hinge to rotate through the bearing. The telescopic positioning rod rotates downward under the action of gravity, and then the positioning rod is in a vertical state. The telescopic positioning rod can be adjusted to a vertical state by simply rotating the telescopic positioning rod once by hand, which makes it convenient for people to position the surveying head.

[0010] The utility model is further configured as follows: the telescopic positioning rod comprises an outer tube, a cavity is formed on the outer tube, an inner tube is slidably connected to the outer tube, and the cavity is used to receive the inner tube.

[0013] By adopting the above technical solution, when the positioning pin needs to be stored in the receiving groove, the positioning pin is rotated and then the flexible part is squeezed by hand. The deformed flexible part occupies the space of the hollow part when it is not deformed, and the overall width of the flexible part and the positioning pin is reduced, so that the positioning pin can be stored in the receiving groove, making it easier for people to store the positioning pin.

[0014] The utility model is further configured as follows: the cross section of the accommodating groove is T-shaped, the width of the accommodating groove opening is smaller than the maximum width of the accommodating groove, and the width of the accommodating groove opening is smaller than the width between the middle parts of the two flexible parts.

[0015] By adopting the above technical solution and setting the cross section of the receiving groove to be T-shaped, when the positioning pin is received in the receiving groove, the flexible member contacts the outer tube, so that the positioning pin will not rotate out of the receiving groove.

[0017] By adopting the above technical solution, when the positioning pin needs to be stored in the receiving groove, the positioning pin is rotated and then the flexible part is squeezed by hand. The deformed flexible part occupies the space of the hollow part when it is not deformed, and the overall width of the flexible part and the positioning pin is reduced, so that the positioning pin can be stored in the receiving groove, making it easier for people to store the positioning pin.

[0018] The utility model is further configured as follows: the cross section of the flexible member is an isosceles triangle, and the sides of the flexible member are provided with chamfers.

[0019] By adopting the above technical solution, when the flexible member rotates, the chamfered edge of the flexible member first contacts the inner tube, making it easier for the flexible member to rotate over the inner tube, thereby making it convenient for people to store the positioning pins.

[0020] The utility model is further configured as follows: the lower end of the inner tube is movably connected to a rubber part, the rubber part includes a connecting part, one end of the connecting part is movably connected to the flexible part, the other end of the connecting part is integrally formed with a cover part, and the cover part is detachably connected to the outer tube.

[0021] By adopting the above technical solution, when the building surveying and mapping device is not in use, the inner tube can be stored in the cavity. At the same time, the rubber part is outside the cavity, and the cover is manually wrapped around the lower end of the outer tube, so that the inner tube cannot slide out freely from the cavity, making it convenient for people to store the inner tube when the building surveying and mapping device is not in use.

[0022] The utility model is further configured as follows: a limiting portion is integrally formed on the lower end of the outer tube, and a convex portion is integrally formed on the upper end of the inner tube.

[0023] By adopting the above technical solution, when the inner tube extends from the outer tube to the limit position, the limiting portion conflicts with the convex portion, preventing the inner tube from separating from the outer tube.

[0024] In summary, the present invention has the following beneficial effects:

[0025] When people unfold the bracket, they move the three support rods away from the center rod by hand, and the connecting rod drives the sliding ring to slide downward until the connecting rod and the center rod are vertical. The positioning pins are turned out from the receiving slots by hand so that the positioning pins and the telescopic positioning rods are in the same straight line and point to the positioning point. Then, the height of the support rods is manually adjusted so that the center rod and the telescopic positioning rods are kept in the same straight line, thereby completing the positioning of the surveying head.
