Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of level staff support, in particular to a level staff support device. BACKGROUND

[0002] The level staff is a tool for measuring height difference and determining the horizontal plane, commonly used in engineering surveying, geographic surveying and construction fields. The level staff is usually used in cooperation with the level instrument to measure the height difference between two points or determine the accurate height of a point.

[0003] When the level staff is used, the vertical state of the level staff needs to be maintained, which is generally achieved by manual supporting and then supporting the level staff with the support rod to maintain the vertical state of the level staff. The measurement is relatively troublesome and needs manual support. CONTENT OF THE UTILITY MODEL

[0004] In order to improve the measurement efficiency, the present application provides a level staff support device.

[0005] The present application provides a level staff support device, which adopts the following technical scheme:

[0006] The level staff support device comprises a support seat and a locking mechanism. A through hole is formed in the middle of the support seat for the level staff to pass through. A support plate is fixedly connected to the edge of the through hole in a vertical manner. The locking mechanism comprises a pull rope. A connecting hole is formed in the support plate for the pull rope to pass through. The two ends of the pull rope pass through the connecting hole together and form a locking cavity with the support plate for the level staff to pass through. The locking mechanism further comprises a tensioning assembly for controlling the pull rope to tightly fix the level staff on the support plate.

[0007] By adopting the above technical scheme, when used, the level staff passes through the through hole and the locking cavity of the support seat, and then the tensioning assembly is used to control the pull rope to tightly fix the level staff on the support plate, so as to realize the support and locking functions of the level staff, which is convenient to operate and does not need manual continuous supporting.

[0008] Optionally, the tensioning assembly comprises a lock disc. An installation seat is fixed on the support seat. The lock disc is rotationally connected to the installation seat. The two ends of the pull rope are fixed on the lock disc and are symmetrically distributed around the central axis of the lock disc. The tensioning assembly further comprises a locking piece for fixing the lock disc.

[0009] By adopting the above technical scheme, the tightness of the pull rope can be controlled by rotating the lock disc, so as to realize the locking or releasing of the level staff.

[0010] Optionally, the locking piece comprises a locking bolt. The locking bolt is threadedly connected to the installation seat. The lock disc is located in the active path of the locking bolt.

[0011] Optionally, both the locking disc and the pull rope are provided in two sets, and transmission teeth are distributed circumferentially around the outer side of the two locking discs around the rotating axis. The two locking discs rotate synchronously through the meshing of the transmission teeth.

[0012] By adopting the above technical solution, when one locking disc is rotated, the other locking disc will also rotate synchronously, thereby ensuring that the two sets of pull ropes can evenly tighten the level gauge, improving the stability and reliability of locking.

[0013] Optionally, a rotating shaft is fixed in the middle of the lock disc, and the lock disc is rotatably connected to the mounting base via the rotating shaft. A handle is fixed to one end of the rotating shaft that passes through the mounting base.

[0014] Optionally, a mounting groove for installing the leveling rod is provided on one side of the support plate.

[0015] Optionally, the upper end face of the support base is threaded with a plurality of leveling bolts at equal intervals around the circumference, and the leveling bolts are perpendicular to the direction of the support base.

[0016] Optionally, the mounting base has an extension plate fixed to the side away from the support base, extending upward toward the lock disc, and the locking bolt is threaded onto the extension plate.

[0017] In summary, this application includes at least one of the following beneficial effects:

[0018] 1. Because the present invention adopts a combination design of support base and locking mechanism, it can automatically straighten and firmly lock the leveling rod, avoiding the tedious operation of continuous manual support and improving measurement efficiency.

[0019] 2. The use of a pull rope in this invention can better adapt to leveling rods of different diameters and provide a stable locking force, further improving the accuracy of the measurement. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] This application discloses a leveling rod support device. (Refer to...) Figure 1 The support device includes a support base 1 and a locking mechanism 2. The support base 1 is used to support the leveling rod 3, and the locking mechanism 2 is used to fix the leveling rod 3 on the support base 1.

[0029] Reference Figure 2 The support base 1 has a through-hole 11 in the middle for the leveling rod 3 to pass through. The diameter of the through-hole 11 is larger than that of the leveling rod 3, making it convenient for the leveling rod 3 to pass through the through-hole 11. A support plate 12 is vertically fixed to the support base 1 along the edge of the through-hole 11. A mounting groove 121 for mounting the leveling rod 3 is provided on one side of the support plate 12. The mounting groove 121 allows the leveling rod 3 to be mounted more stably on the support plate 12, reducing shaking and offset during use, thereby improving the accuracy of measurement.

[0030] The locking mechanism 2 includes a pull rope 21, and a connecting hole 122 is provided on the support plate 12 for the pull rope 21 to pass through. Both ends of the pull rope 21 pass through the connecting hole 122 together, forming a locking cavity with the support plate 12 for the leveling rod 3 to pass through. The locking mechanism 2 also includes a tensioning component 22, which can control the pull rope 21 to tighten when the leveling rod 3 passes through the locking cavity, and tighten and fix the leveling rod 3 to the support plate 12.

[0031] Reference Figure 3 The tensioning assembly 22 includes a locking disc 221 and a locking element 222. A mounting base 14 is vertically fixed on the support base 1, and the locking disc 221 is rotatably connected to the mounting base 14 via a rotating shaft. Both ends of the pull rope 21 are fixed to the locking disc 221 and are symmetrically distributed around the central axis of the locking disc 221. A handle 223 is fixed to one end of the rotating shaft of the locking disc 221 that passes through the mounting base 14. By rotating the handle 223, the locking disc 221 can be easily driven to rotate, thereby controlling the tension of the pull rope 21.

[0032] The locking element 222 includes a locking bolt. An extension plate 141 extending upward toward the locking disc 221 is fixed on the side of the mounting base 14 away from the support base 1. The locking bolt is threaded onto the extension plate 141 and can be rotated through the extension plate 141 and then pressed against the outer periphery of the locking disc 221 to achieve the fixing or release of the locking disc 221.

[0033] Reference Figure 3To improve the fixing effect on the leveling rod 3, in this embodiment, two sets of locking discs 221 and pull ropes 21 are provided. The two locking discs 221 are distributed vertically along the mounting base 14. Transmission teeth 2211 are evenly distributed around the outer side of the two locking discs 221 in the circumferential direction around the rotation axis. The two locking discs 221 rotate synchronously through the meshing of the transmission teeth 2211. When one locking disc 221 rotates, the other locking disc 221 will also rotate synchronously, thereby ensuring that the two sets of pull ropes 21 can evenly tighten the leveling rod 3, improving the stability and reliability of the locking.

[0034] Reference Figure 3 The upper surface of the support base 1 is threaded with several leveling bolts 13 at equal intervals around its circumference. The leveling bolts 13 are perpendicular to the direction of the support base 1. By rotating the leveling bolts 13, the levelness of the support base 1 can be finely adjusted to adapt to different measurement environments and terrain conditions, ensuring the verticality of the leveling rod 3. The number of leveling bolts 13 can be selected according to the actual situation; this embodiment uses three as an example.

[0035] The implementation principle of a leveling rod support device in this application is as follows:

[0036] In use, the horizontal position of the support base 1 is adjusted by adjusting the leveling bolt 13, the leveling rod 3 is passed through the through 11 and the locking cavity of the support base 1, and then the leveling rod 3 is tightened and fixed on the support plate 12 by controlling the pull rope 21 through the locking disc 221 and the locking bolt, thus achieving the fixation of the leveling rod 3.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
