Description

Forestry geological compass

technical field

The utility model belongs to the field of measuring instruments, in particular to a forestry geological compass.

Background technique

Geological compass has multiple measurement functions such as magnetic orientation and distance, level, height difference, slope angle, etc., such as DQL-12Z forest compass produced by Harbin Optical Instrument Factory, DSL-1 produced by Shanghai Longtuo Instrument Equipment Co., Ltd. Geological compass, etc., mainly composed of tripod, horizontal mechanism, compass and telescope, is an indispensable measurement tool for field work and one of the necessary tools for forestry surveys; Leveling is to adjust the compass to a horizontal state through a horizontal mechanism. The current geological compass has the problems of high leveling difficulty and slow speed, which brings inconvenience to forestry survey work.

Contents of the invention

The purpose of the utility model is to provide a forestry geological compass in order to solve the problems of difficult leveling and slow speed in the current geological compass, and its technical scheme is as follows:

A forestry geological compass, which includes a tripod, a horizontal mechanism, a compass and a telescope, the tripod is connected to the compass through a horizontal mechanism, a bubble-type level is arranged inside the compass, the telescope is set above the compass, and the horizontal mechanism contains an arc The two ends of the arc-shaped bracket are respectively provided with a collar, one end of the arc-shaped bracket is connected with the corresponding collar along the opening and closing direction, and the other end of the arc-shaped bracket is connected with the corresponding collar through the foot screw. The height adjuster is connected, and a shaft with an axis on a straight line is arranged on the opposite sides of the compass. The shaft is fixedly connected with the compass. The diameter of the shaft is less than or equal to the inner diameter of the collar, and the two shafts are respectively set In a collar, a top screw is set on each collar, the level of the compass along the shaft direction can be adjusted through the foot screw, and at the same time, the shaft can be rotated to adjust the level of the compass and the vertical direction of the shaft, with both hands at the same time, After adjustment, it is fixed with a top screw, and a driving lever perpendicular to the shaft is set on a shaft to facilitate the rotation of the shaft, and the middle position of the arc-shaped support is connected with the triangular support.

The beneficial effect of the utility model is that the rapid horizontal adjustment can be performed simultaneously with both hands, which is simple and convenient.

detailed description:

With reference to Fig. 1 and Fig. 2, a kind of forestry geological compass, it comprises tripod 1, horizontal mechanism 2, compass 3 and telescope 4, tripod 1 is connected with compass 3 by horizontal mechanism 2, is provided with bubble type in compass 3 The spirit level 3-1 and the telescope 4 are arranged on the top of the compass 3. The horizontal mechanism 2 includes an arc-shaped support 2-1, and a collar 2-2 is respectively arranged at the two ends of the arc-shaped support 2-1. One end of the bracket 2-1 is rotationally connected with the corresponding collar 2-2 along the opening and closing direction, and the other end of the arc-shaped bracket 2-1 is connected with the corresponding collar 2-2 through a height adjuster such as the foot screw 2-3 , on the opposite sides of the compass 3, a shaft 3-2 with an axis on a straight line is respectively arranged, the shaft 3-2 is fixedly connected with the compass 3, and the diameter of the shaft 3-2 is smaller than or equal to the collar 2-2 The inner diameter of two shaft rods 3-2 is respectively set in a collar 2-2, and a top screw 2-2-1 is respectively set on each collar 2-2, which can be adjusted by the foot screw 2-3 The level of the compass 3 along the direction of the shaft 3-2, while rotating the shaft 3-2 to adjust the level of the compass 3 and the vertical direction of the shaft 3-2, both hands at the same time, after the adjustment is fixed with the top screw 2-2-1, in the A shaft rod 3-2 is provided with a driving rod 3-3 perpendicular to the shaft rod 3-2, and it is convenient and labor-saving to toggle the driving rod 3-3 to rotate the shaft rod 3-2. The middle position is connected with the tripod 1 .

Preferably, the driving rod 3-3 is threadedly connected with the shaft rod 3-2, which is convenient for disassembly and carrying.

Preferably, the driving lever 3-3 is vertically arranged with the compass 3, and the self-weight of the driving lever 3-3 is conducive to keeping the compass 3 horizontal.

Preferably, the length of the driving rod 3-3 is greater than fifty centimeters, which is labor-saving and convenient for fine-tuning.
