Abstract

The utility model discloses an optical automatic vertical angle instrument which is composed of an outer shell, an object lens, a prism, and an eye lens. A vertical angle disc which is composed of a transparent shell, a rotary shaft and a transparent rotary disc is arranged between the object lens and the prism. The edge of the transparent shell is provided with angle scales. The rotary shaft penetrates through the center of transparent shell and the transparent rotary disc. The transparent rotary disc is arranged in the transparent shell. The lower end of the transparent rotary disc is provided with a balancing weight, and the upper end of the transparent rotary disc is provided with an indicating needle. The utility model has the advantages of small size, light weight, convenient operation, high measuring precision, etc. Because the utility model adopts the vertical angle disc which is composed of the transparent shell and the transparent rotary disc, the verticality of a measured object can be directly observed through the eye lens.

Description

The automatic vertical angle instrument of optics

The utility model belongs to a kind of surveying instrument.

Traditional vertical angle instrument generally all can not observe directly the verticality of testee, and needs to record by means of other means the verticality of testee, so not only uses inconvenience, and measuring accuracy is affected.In addition, contrast taller and bigger testee, need to come subsidiary with other accurate valuable instrument.

The purpose of this utility model is: provide a kind of simple, light, vertical angle measuring instrument intuitively, to address the above problem.

The utility model is to constitute like this: it is by shell (1), object lens (2), and eyepiece (4) is formed, and object lens (2) are contained in the front of shell (1), and eyepiece (4) is contained in the rear end of shell (1); Between object lens (2) and eyepiece (4) vertical angle scale (5) is housed, it is by transparent shell (6), rotating shaft (7), and transparent rotating disk (8) is formed; There is angle index (9) at the edge of transparent shell (6); Rotating shaft (7) is through at the center of transparent shell (6) and transparent rotating disk (8); Transparent rotating disk (8) is located in the transparent shell (6), and there is balancing weight (10) its lower end, and there is pointer (11) upper end.

The utility model compared with prior art, it is little, in light weight, easy to use to have a volume, the measuring accuracy advantages of higher.Owing to adopt transparent shell (6) and transparent rotating disk (8) to form vertical angle scale (5), make it can directly from eyepiece (4), observe the verticality of testee; The balancing weight (10) of transparent rotating disk (8) lower end is that the pointer (11) of its upper end is indicated in vertical direction, and the difference of angle index 0 degree on pointer (11) and the transparent shell (6) is then reacted the differential seat angle of testee.

Accompanying drawing 1 is a structure principle chart of the present utility model;

Accompanying drawing 2 is the floor map of the utility model vertical angle scale (5).

Embodiment of the present utility model: object lens (2) are contained in the front of shell (1), the cased corner of prism (3), eyepiece (4) is contained in the rear end of shell (1); Between object lens (2) and prism (3) vertical angle scale (5) is housed, it is by transparent shell (6), rotating shaft (7), and transparent rotating disk (8) is formed; There is angle index (9) at the edge of transparent shell (6); Rotating shaft (7) is through at the center of transparent shell (6) and transparent rotating disk (8); Transparent rotating disk (8) is located in the transparent shell (5), and there is balancing weight (10) its lower end, and there is pointer (11) upper end.The clean oil of packing in transparent shell (6) is to reduce the moment of inertia of transparent rotating disk (8).

Claims

1, the automatic vertical angle instrument of a kind of optics, it is by shell (1), object lens (2), eyepiece (4) is formed, and object lens (2) are contained in the front of shell (1), and eyepiece (4) is contained in the rear end of shell (1), it is characterized in that: between object lens (2) and eyepiece (4), vertical angle scale (5) is housed, it is by transparent shell (6), rotating shaft (7), and transparent rotating disk (8) is formed; There is angle index (9) at the edge of transparent shell (6); Rotating shaft (7) is through at the center of transparent shell (6) and transparent rotating disk (8); Transparent rotating disk (8) is located in the transparent shell (6), and there is balancing weight (10) its lower end, and there is pointer (11) upper end.
