Description

Technical Field

[0001] The utility model relates to the technical field of tower rulers, in particular to a novel tower ruler for land resource surveying and mapping. Background Art

[0002] A tower ruler is a type of level ruler. Because its shape resembles a tower, it is often called a tower ruler. It is a commonly used tool for land resource surveying and mapping.

[0003] Through searching, it was found that the Chinese patent publication number CN220893374U disclosed "A Land Resources Surveying Tower Ruler" addresses the problem that the existing tower ruler is prone to deflect to one side and cannot be positioned during use. By positioning the tower ruler in the middle position of the positioning platform, the tower ruler is guaranteed to be stable under the joint limiting action of the positioning platform, the through hole, and the limiting plate, thereby avoiding the positioning platform from tilting to one side during use. The common support height of the first bracket and the second bracket can also be adjusted to adapt to the positioning requirements of tower rulers of different lengths, thereby avoiding the situation where the center of gravity of the tower ruler is too high and shaking after positioning. The first bracket can move up and down along the inner cavity of the second bracket and achieve positioning, and the position of the first bracket in the inner cavity of the second bracket can be flexibly adjusted.

[0004] However, the above-mentioned land resource surveying and mapping tower uses conical support feet on flat ground, which is not only easy to damage soft ground, but also easy to cause wear of the support feet on hard ground. Utility Model Content

A knob is rotatably connected to the front side of the left end of the baffle. A second screw rod is fixedly connected to the right end of the knob. A spring is fixedly connected to the opposite sides of the frame body and the baffle. The other end of the spring is fixedly connected to a pressing rod. The other end of the pressing rod is movably connected to a ball.

[0010] Preferably, the telescopic support rod includes a sleeve. An extension rod is slidably connected to the lower end of the sleeve. A rotating ring is threadedly connected to the outer surface of the extension rod. The sleeve is rotatably connected to the rotating ring.

[0011] Preferably, the insertion block includes a moving rod. Insertion rods are fixedly connected to both sides of the lower end of the moving rod.

[0012] Preferably, the base is slidably connected to the moving rod. The first screw rod is threadedly connected to the moving rod. Two slots adapted to the insertion rods are provided on the base.

[0013] Preferably, the mounting base is rotatably connected to the fixed base. A threaded hole matching the second screw rod is provided on the front side of the left end of the frame body.

[0014] Preferably, several pressing rods are provided. The several pressing rods are symmetrically distributed on the inner side walls of the frame body and the baffle and are respectively slidably connected to the frame body and the baffle.

[0015] Preferably, a positioning piece is fixedly connected to the side of the baffle close to the frame body. A spirit level is provided on the upper end of the mounting base.

[0016] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0017] First, by opening the telescopic support rod, the base contacts the ground. The torsion spring is used to drive the base to reset, facilitating stable support on a flat ground. By rotating the handle, the handle drives the first screw rod to rotate, enabling the insertion block to be inserted into the ground, thereby achieving stable support on rough ground, so as to achieve stable support for different terrains and maintain the aesthetic appearance of the flat ground.

[0018] Second, by fitting the leveling staff to the left side of the frame body and rotating the baffle to close it, by rotating the knob, the knob drives the second screw rod to rotate. The second screw rod is screwed tightly with the frame body to fix the baffle to the frame body. Under the action of the spring, the pressing rod is pushed to make the ball fit with the leveling staff, so that when the leveling staff slides up and down, the ball can roll, reducing the friction force, thereby achieving the effects of facilitating the disassembly and assembly of the leveling staff and reducing wear.
