Description

Technical Field

[0001] The utility model relates to the technical field of benchmarks, in particular to a benchmark for building surveying and mapping. Background Technique

[0002] A benchmark for building surveying and mapping is a tool used to measure and mark the ground elevation or position, mainly used for surveying work in construction projects. The benchmark is usually made of metal or hard wood, and has obvious scale marks on the surface for easy reading. The height of the benchmark can be customized according to actual needs, and the common length range is from several meters to more than ten meters.

[0003] Based on the above, the inventor of the present utility model found the following problems: In order to improve portability, the current surveying and mapping benchmarks are usually assembled structures, which are composed of multiple short benchmarks combined and fixed into a long benchmark. However, this installation method is relatively cumbersome and not convenient to use. Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a benchmark for building surveying and mapping is provided, in order to achieve the purpose of having more practical value. Content of the Utility Model

[0004] The purpose of the present utility model is to provide a benchmark for building surveying and mapping to solve the problems raised in the above background technique.

Folding assemblies are provided between the first rod body, the second rod body, the third rod body, and the fourth rod body. Folding grooves are opened at one ends of the first rod body and the fourth rod body and at both ends of the second rod body and the third rod body. Folding blocks are fixedly installed inside the folding grooves. A sliding groove is opened on one side of the folding block, and a fixing hole is opened at the bottom of the sliding groove. The folding assembly includes a folding shaft. Insertion heads are provided at both ends of the folding shaft. A cavity is opened inside the folding shaft, and two synchronizing pieces are fixedly installed inside the folding shaft. A top push spring is fixedly installed between the two synchronizing pieces. Insertion blocks are fixedly installed on one side at both ends of the synchronizing piece. The insertion blocks pass through the side surface of the insertion head, and the insertion blocks are slidably connected with the sliding groove.

[0005] By adopting the above technical solutions, folding assemblies are provided between the first rod body, the second rod body, the third rod body, and the fourth rod body, which is convenient for folding the benchmark assembly and improving the portability of the device. A top push spring is fixedly installed between the two synchronizing pieces, which is convenient for the top push spring to provide elastic force to push the two synchronizing pieces away from each other. The insertion blocks pass through the side surface of the insertion head, and the insertion blocks are slidably connected with the sliding groove, which is convenient for folding the benchmark assembly and can insert the insertion head into the folding groove when unfolded. When the insertion head is completely inserted, the elastic force of the top push spring pushes the insertion blocks outwards, so that the insertion blocks are inserted into the fixing holes to keep the benchmark assembly fixed in the unfolded state for convenient use.

[0006] Further, a button is fixedly installed in the middle of one side of the synchronization piece, and one end of the button is arranged outside the folding shaft.

[0007] By adopting the above technical solution, since a button is fixedly installed in the middle of one side of the synchronization piece and one end of the button is arranged outside the folding shaft, it is convenient to press the button to draw out the insertion block from the fixing hole when folding the device, facilitating the extraction of the insertion head, thereby folding the benchmark component, reducing the storage volume, and improving the portability.

[0008] Further, fixing blocks are fixedly installed at both ends of the inner cavity of the folding shaft, and guide rods are fixedly installed on both sides of the fixing blocks. By adopting the above technical solution, since fixing blocks are fixedly installed at both ends of the inner cavity of the folding shaft and guide rods are fixedly installed on both sides of the fixing blocks, it is convenient to fixedly install the guide rods inside the folding shaft.

[0009] Further, guide holes are formed in the middle of both ends of the synchronization piece, and the guide rods pass through the guide holes, and the guide rods are slidably connected to the guide holes.

[0010] By adopting the above technical solution, since the guide rods pass through the guide holes and the guide rods are slidably connected to the guide holes, it is convenient to guide the movement of the synchronization piece and improve the stability of the movement of the synchronization piece when pressing the button.

[0011] Further, a mounting head is fixedly installed at one end of the first rod body away from the folding groove, and a threaded head and an anti-loosening rubber ring are fixedly installed on the top of the mounting head.

[0012] By adopting the above technical solution, since a mounting head is fixedly installed at one end of the first rod body away from the folding groove and a threaded head and an anti-loosening rubber ring are fixedly installed on the top of the mounting head, it is convenient to fixedly install the total station prism.

[0013] Further, a metal foot is fixedly installed at one end of the fourth rod body away from the folding groove.

[0014] By adopting the above technical solution, since a metal foot is fixedly installed at one end of the fourth rod body away from the folding groove, it is convenient to reduce the direct contact between the bottom of the device and the ground, thereby reducing wear and extending the service life of the device.

[0015] Further, a fixing band is sleeved outside the middle of the third rod body, and a male sticker and a female sticker of a mother-child sticker are respectively arranged on both sides of the fixing band.

[0016] By adopting the above technical solution, since a male sticker and a female sticker of a mother-child sticker are respectively arranged on both sides of the fixing band, it is convenient to wind and fix the folding state of the device to avoid damage caused by loosening and collision during transportation.

[0019] Further, two level bars are provided on the other side of the rotating ring, and the two level bars are arranged perpendicular to each other.

[0020] By adopting the above technical solution, since two level bars are provided on the other side of the rotating ring and the two level bars are arranged perpendicular to each other, it is convenient to indicate whether the benchmark assembly in the unfolded state is vertical.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows: Folding assemblies are provided between the first rod body, the second rod body, the third rod body and the fourth rod body, which is convenient for folding the benchmark assembly and improves the portability of the device.
