Description

Technical Field

[0001] The utility model relates to the field of surveying and mapping poles, in particular to a surveying and mapping pole which is convenient for adjusting the height. Background Art

[0002] Land engineering is a comprehensive discipline that includes land development, land consolidation, land reclamation and land restoration. It not only focuses on the rational use of land resources, but also involves land planning, design, construction and management. Graduates of land consolidation engineering have broad employment prospects and can engage in surveying, planning, design, construction, management and other work in related fields such as land, water conservancy, and ecological restoration. Usually, rangefinders are needed in conjunction with surveying poles to collect data during surveying and planning.

[0003] However, the height adjustment of the current surveying pole is mostly controlled by bolts. When the height needs to be adjusted frequently during the surveying process, the knob needs to be tightened and loosened many times, which is inconvenient. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a surveying pole that is easy to adjust in height, thereby solving the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a surveying rod that is easy to adjust the height, comprising a surveying rod, the surveying rod comprising: a holding sleeve rod and an extension rod, a sleeve is installed on one side of the upper end of the holding sleeve rod, a pull pin rod is provided inside the sleeve, a magnet is installed on one end of the pull pin rod, a limiting slot is provided on the side surface of the extension rod corresponding to the position of the magnet, the outer side of the pull pin rod is located on the inner side of the sleeve and is sleeved with a spring, a clamping seat is installed on the outer side of the upper end of the holding sleeve rod, and a fastening bolt is installed on one side end of the clamping seat.

[0006] As a further solution of the present invention: a scale mark is provided on the side of the extension rod away from the limit slot, and a mounting joint is installed on the upper end of the extension rod.

[0007] As a further solution of the present invention: a bottom plug is installed at the lower end of the holding sleeve rod, a mounting ear plate is provided on the outer side of the lower end of the holding sleeve rod, a rotating shaft is installed inside the mounting ear plate, and a diagonal support rod is installed on the outer side of the rotating shaft.

[0008] As a further solution of the present invention: a magnetic gasket is installed on the inner side wall of the limit slot, and the holding sleeve rod and the extension rod are both made of aluminum alloy.

[0009] As a further solution of the present invention: a horizontal bubble is installed on the upper surface of the clamping seat.

[0010] As a further solution of the present invention: the extension rod is movably connected to the grip sleeve rod.

[0011] As a further solution of the present invention: the spring is fixedly connected to the magnet and the sleeve.

[0012] As a further solution of the present invention: the diagonal support rod is fixedly connected to the rotating shaft, and the rotating shaft is rotatably connected to the mounting ear plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] After the magnet is adsorbed inside the limit slot, the extension rod can be stably limited inside the holding sleeve rod under the elastic force of the spring. Therefore, it is possible to avoid the need to loosen and tighten the bolts multiple times during a surveying process, making adjustment more convenient.

[0015] After inserting the bottom plug at the lower end of the holding sleeve rod into the surveying ground, the diagonal support rod is moved as a whole inside the mounting ear plate using the rotating shaft to ensure the stability of the surveying rod placement. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-5 As shown, this embodiment provides a surveying rod that is easy to adjust the height, including a surveying rod 1, and the surveying rod 1 includes: a holding sleeve rod 2, an extension rod 3, the holding sleeve rod 2 and the extension rod 3 are both aluminum alloy components, the extension rod 3 is movably connected to the holding sleeve rod 2, and a sleeve 201 is installed on one side of the upper end of the holding sleeve rod 2, and a pull pin rod 8 is provided inside the sleeve 201. A magnet 801 is installed at one end of the pull pin rod 8, and a spring 202 is fixedly connected to the magnet 801 and the sleeve 201. A limiting slot 301 is provided on the side surface of the extension rod 3 corresponding to the position of the magnet 801, and a magnetic gasket is installed on the inner side wall of the limiting slot 301. The outer side of the pull pin rod 8 is located on the inner side of the sleeve 201 and is sleeved with a spring 202. A clamping seat 4 is installed on the outer side of the upper end of the holding sleeve rod 2, and a fastening bolt 401 is installed on one side end of the clamping seat 4.

[0024] like Figure 2-3 As shown, in this embodiment, the extension rod 3 is provided with a scale mark 302 on the side away from the limit slot 301, a horizontal bubble 402 is installed on the upper surface of the clamping seat 4, the upper end of the extension rod 3 is provided with a mounting joint 5, the lower end of the holding sleeve rod 2 is provided with a bottom plug 6, and the outer side of the lower end of the holding sleeve rod 2 is provided with a mounting ear plate 701, and the interior of the mounting ear plate 701 is provided with a rotating shaft 702, and the rotating shaft 702 is rotatably connected to the mounting ear plate 701, and the outer side of the rotating shaft 702 is provided with a diagonal support rod 7, and the diagonal support rod 7 is fixedly connected to the rotating shaft 702.

[0025] The working principle of the present invention is as follows: before use, a torque is applied to the fastening bolt 401 on the outside of the clamping seat 4, and the locking and clamping effect of the fastening bolt 401 on the holding sleeve rod 2 and the extension rod 3 is loosened. After the bottom plug 6 at the lower end of the holding sleeve rod 2 is inserted into the surveying ground, the diagonal support rod 7 is moved as a whole inside the mounting ear plate 701 by using the rotating shaft 702, and the verticality of the surveying rod 1 is adjusted by coordinating with the horizontal bubble 402 above the clamping seat 4. Then, the pull pin rod 8 is stretched outward as a whole to tighten the spring 2. 02 is compressed and stored in the sleeve 201 as a whole, so the magnet 801 breaks the adsorption effect with the gasket inside the limiting slot 301, and the extension rod 3 can be controlled to hold the free movement inside the sleeve rod 2 as a whole. After the scale corresponding to the scale mark 302 on the outside of the extension rod 3 is exposed, the force on the pull pin rod 8 is released, and the spring 202 pushes the magnet 801 to be adsorbed inside the limiting slot 301 to position the extension rod 3. Therefore, the overall height adjustment of the surveying rod 1 during a surveying process is more convenient.
