Abstract

The utility model relates to a vertical facade compass comprising a magnetic needle and a driving shaft (2) containing a driving shaft tip (8) characterized in that the magnetic needle is an increasing and overstriking magnetic bar (1); the lower end of the driving shaft (2) is the driving shaft tip (8), the upper end is a driving bevel wheel (3), a driving shaft bearing (7) is arranged in the driving shaft (2); one end of a driven shaft (5) is the vertical facade compass (6), the other end is a driven bevel wheel (4), a driven shaft bearing (9) is arranged in the driven shaft (5); a driving bevel wheel (3) is engaged with the driven bevel wheel (4).

Description

The vertical elevation compass

Technical field

The utility model relates to a kind of compass of vertical elevation.

Background technology

The magnet compass be Chinese thousands of year before institute invents, but inquire about the search that reaches at home painstakingly through online, still find no any magnet compass with the vertical elevation demonstration a few days ago.

Summary of the invention

The purpose of this utility model is: the magnet compass at the conventional planar demonstration can not convert the problem that vertical elevation shows to, and a kind of vertical elevation compass is provided.

Technical solution of the present utility model is: a kind of vertical elevation compass, comprise the magnet pin, and contain the main drive shaft (2) of main drive shaft pivot (8), it is characterized in that: described magnet pin is for strengthening the bar magnet (1) of overstriking; The lower end of described main drive shaft (2) is main drive shaft pivot (8), and the upper end is active oblique gear (3), is provided with drive shaft bearing (7) in the main drive shaft (2); Driven shaft (5) one ends are vertical elevation compass (6), and the other end is driven spiral gear (4), is provided with driven shaft bearing (9) in the driven shaft (5); Described active oblique gear (3) and driven spiral gear (4) engagement.

In technical solution of the present utility model: drive shaft bearing (7) is positioned on the main drive shaft (2) by first snap ring (10); Driven shaft bearing (9) is positioned on the driven shaft (5) by second snap ring (11) and the 3rd snap ring (12).

The beneficial effects of the utility model: its advantage is to watch compass with the eye of looking squarely, this is particularly important for the people who drives, the compass that dome-type is arranged on the market, mainly also be to show in a horizontal manner, but can see when looking squarely that it points to direction after one's death, other three directions will and judge and could to confirm with thinking, inconvenience, and what be not so good as that the utility model can be direct and clear and definite finds out each orientation, all directions.

Description of drawings

Fig. 1 is the inside primary structure synoptic diagram of vertical elevation compass.

Among the figure: 1, bar magnet, 2, main drive shaft, 3, active oblique gear, 4, driven spiral gear, 5, driven shaft, 6, the vertical elevation compass, 7, drive shaft bearing, 8, the main drive shaft pivot, 9, driven shaft bearing, 10, first snap ring, 11, second snap ring, the 12, the 3rd snap ring.

Embodiment

The contrast accompanying drawing, with the inner primary structure explanation of the utility model, at first bar magnet 1 has the function of indication North and South direction, and the torsion of its rotation is through main drive shaft 2 and active oblique gear 3 is passed to driven spiral gear 4 and driven shaft 5 drives vertical elevation compass 6 direction indications; Drive shaft bearing 7 and main drive shaft pivot 8 are in order to support main drive shaft 2, driven shaft bearing 9 is in order to support driven shaft 5, drive shaft bearing 7 and driven shaft bearing 9 are to be fixed on the compass base structure, 8 of main drive shaft pivots insert on the base structure, and actual installation fashion should be provided with second snap ring 11 and the 3rd snap ring 12 to limit moving axially of master and slave moving axis being provided with on the main drive shaft on first snap ring 10, the driven shaft 5.Because of driving and driven spiral gear size form unanimity, guarantee that bar magnet 1 can be synchronously consistent with vertical elevation compass 6 direction indications.

Claims

1, a kind of vertical elevation compass comprises the magnet pin, contains the main drive shaft (2) of main drive shaft pivot (8), it is characterized in that: described magnet pin is for strengthening the bar magnet (1) of overstriking; The lower end of described main drive shaft (2) is main drive shaft pivot (8), and the upper end is active oblique gear (3), is provided with drive shaft bearing (7) in the main drive shaft (2); Driven shaft (5) one ends are vertical elevation compass (6), and the other end is driven spiral gear (4), is provided with driven shaft bearing (9) in the driven shaft (5); Described active oblique gear (3) and driven spiral gear (4) engagement.

2, vertical elevation compass according to claim 1 is characterized in that: drive shaft bearing (7) is positioned on the main drive shaft (2) by first snap ring (10); Driven shaft bearing (9) is positioned on the driven shaft (5) by second snap ring (11) and the 3rd snap ring (12); Intermeshing active oblique gear (3), driven spiral gear (4) size unanimity.
