Description

Technical Field

[0001] The utility model relates to the technical field of engineering surveying and mapping equipment, in particular to an auxiliary fixing structure of surveying and mapping equipment for surveying and mapping engineering. Background Art

[0002] Engineering surveying and mapping is an essential part of the preliminary preparation for engineering construction. By using appropriate surveying and mapping instruments to conduct detailed measurements of the geographic information of the construction area, subsequent construction can be made safer and more reliable.

[0003] Publication No. CN219473284U discloses an auxiliary fixing structure for engineering surveying and mapping equipment, which is provided with a series of structures to facilitate the change of surveying height and angle during surveying and mapping, and the overall structure can be disassembled for easy transportation and storage. However, the equipment cannot be stably fixed on the ground during use, and can only be inserted into the ground by nails. Its stability is poor and it is easy to fall over when no one supports it. Therefore, we propose an auxiliary fixing structure for surveying and mapping equipment for surveying and mapping engineering. Utility Model Content

The interior of the rotating hinge is fixedly connected to a limiting tooth, the top end of the limiting tooth is provided with a latch tooth, and the top end of the latch tooth is fixedly connected to a reset adjustment buckle.

[0007] By adopting the above technical solution, the upper and lower support arms can be adjusted and inserted directly or obliquely into the ground, so that the support arms can be fixed on the ground conveniently. The support arms can be fixed according to different land forms relatively conveniently, thereby improving the efficiency of installing and fixing the support frame and helping the support frame to be fixed on the ground through auxiliary fixing parts, thereby reducing the possibility of equipment damage caused by the support frame tipping over due to external reasons when there is no one to support the surveyor when observing the on-site situation.

[0008] Specifically, an expansion tube is inserted through the bolt insertion hole, and a fixing bolt is threadedly connected to the interior of the expansion tube.

[0009] By adopting the above technical solution, expansion bolts corresponding to common models are used to assist in fixing the equipment bracket.

[0010] Specifically, the limit tooth rotates by pulling the reset adjustment buckle to drive the locking tooth to move upward.

[0011] By adopting the above technical solution, the lower support arm is rotated by pulling the reset adjustment buckle, thereby adjusting the angle at which the lower support arm is inserted into the ground.

[0012] Specifically, a plurality of grounding pins for increasing the contact area are installed at the bottom end of the auxiliary fixing member.

[0013] By adopting the above technical solution, the friction area is increased by using the grounding nails, thereby reducing the occurrence of tipping.

[0014] Specifically, a through hole matching the position and size of the connecting piece is opened at the bottom end of the lower support arm, and the through plug passes through the through hole opened by the lower support arm and the connecting piece for connection and fixation, and the through plug passes through the lower support arm and one end of the connecting piece and is rotatably connected with a locking piece.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The technical solution of the present application provides an additional auxiliary support structure to fix the surveying and mapping bracket to the ground through the structural design of the lower support arm, connecting parts, through-holes, through-plugs, auxiliary fixing parts, bolt holes, fixing bolts, expansion tubes and grounding nails, and reduces the possibility of the equipment tipping over when there is no support through the external connection and fixing method, thereby further improving the stability of the surveying and mapping bracket.
