Embodiment 1

[0020] Embodiment one, see figure 1 , a horizontally adjustable theodolite includes a base 2 and an aiming part 1 vertically placed on the base. The collimator 1 includes a telescope 11 . The above are prior art.

[0021] The base 2 is provided with three supporting feet 56 distributed in a triangle. The supporting foot 56 includes an upper section 561 and a lower section 562 . The upper end of the upper section 561 is connected with the base 5 . The lower end of the upper section 561 is provided with a sliding hole 563 . The sliding hole 563 extends in the up and down direction. The sliding hole 563 communicates with the oil bag 565 through the oil pipe 564 . The oil pipe 564 is provided with a valve 566 . The upper end of the lower section 562 is sealed and slidably connected in the sliding hole 563 .

[0022] When in use, adjust the level of the base by extending the shorter support legs. The method of extending the supporting leg is: open the valve, hold the liqui...

Embodiment 2

[0029] Embodiment two, the difference with embodiment one is:

[0030] see Figure 5 , the inner cylinder 4 includes an inner tube 45 and an outer tube 44 . The outer ring gear 51 is connected to the outer tube 44 . The inner tube 4 is connected together with the telescope through the outer tube in rotation. The inner tube 45 is spherically hinged in the outer tube 44 . The mirror layer 41 is provided on the inner surface of the inner tube 45 . The inner tube 45 protrudes from the inner surface of the outer tube 44 . During use, the inner tube 45 is rotated so that the light is irradiated on the mirror layer to the maximum extent and is reflected.

Abstract

The invention relates to a theodolite, in particular to a level adjustable theodolite. The level adjustable theodolite comprises a base and an alidade vertically arranged on the base, wherein the alidade comprises a telescope. The level adjustable theodolite is characterized in that the base is provided with three supporting legs in triangular distribution, each supporting leg comprises an upper segment and a lower segment, the upper end of each upper segment is connected with the base together, a slide opening is formed in the lower end of each upper segment, each side opening is communicated with an oil sac by virtue of an oil tube, a valve is arranged on the oil tube, and the upper end of each lower segment is hermetically and slidably connected in the corresponding slide opening. The invention aims at providing a level adjustable theodolite with the base capable of adjusting the level, and the problem that the base of an existing theodolite can not adjust the level is solved.

Description

technical field [0001] The invention relates to a theodolite, in particular to a horizontally adjustable theodolite. Background technique [0002] Theodolite is a measuring instrument designed according to the principle of angle measurement to measure horizontal and vertical angles. Divided into optical theodolite and electronic theodolite, the most commonly used one is the electronic theodolite at present. The theodolite is the mechanical part of the telescope. It has two mutually perpendicular rotation axes to adjust the azimuth and horizontal height of the telescope so that the telescope can point in different directions. The existing theodolite also has the following disadvantages: when the ambient temperature is cold, it cannot be heated to increase the temperature of the telescope, and the telescope in the theodolite will affect the observation effect when the ambient temperature is too large or too small; the base cannot be adjusted. Contents of the invention [0...
