Description

Multifunctional compass location

Technical field

The utility model relates to compass, is in particular worn on the Multifunctional compass location in wrist.

Background technology

Compass is one of four inventions of China, is widely used in navigational field, is also the basic introduction knowledge that people understand the Nature simultaneously.The arctic can be pointed to all the time in the arctic of compass needle, not only as toy, can also increase the enjoyment of children for learning.Existing compass is formed primarily of a compass and needle, and structure function is too simple.

Utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of by the Multifunctional compass location of magnifier, mirror, compass.

For achieving the above object, technical solution of the present utility model is: Multifunctional compass location, include the compass being installed on a base, the two ends of described base connect a wrist strap, described base is also provided with dumb card, be installed on below base, described dumb card is hinged with the straight-bar vertically rotated described dumb card drawing and pulling type, described dumb card has the groove embedded for straight-bar.

Preferably, described base includes magnifier, and described magnifier is articulated with base with horizontally rotating.

Preferably, described base also includes level crossing, and described level crossing is positioned at immediately below magnifier.

Preferably, described wrist strap is elastic wristband.

By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: the utility model is worn on wrist by wrist strap, and structure is simple, easy to use.This structure also in conjunction with dumb card, magnifier, level crossing etc., has several functions, increase its interest, be particularly suitable as exploration instrument outside children's room, and each component layouts is reasonable, ensures that one-piece construction is flexibly small and exquisite.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is the structural representation of base;

(1, base; 11, wrist strap catching groove; 2, wrist strap; 3, compass; 4, dumb card; 41, straight-bar; 42, groove; 5, magnifier; 6, level crossing).

Embodiment

The utility model is further illustrated below in conjunction with the drawings and specific embodiments.

As illustrated in fig. 1 and 2, Multifunctional compass location, compass 3 is installed on a base 1.The two ends of described base 1 are provided with wrist strap catching groove 11, are dismountablely respectively connected to a wrist strap 2, and wrist strap 2 is elastic wristband, by this wrist strap 2, compass 2 is worn on wrist place; Described compass 3 can be not with pointer but rotating disk can the compass of autorotation.There is a drawing and pulling type dumb card 4 below of described compass 3, dumb card 4 has a straight-bar that can vertically rotate 41, and can be rotated by horizontal positioned is setting, and during setting, straight-bar 41, perpendicular to dumb card 4, dumb card 4 has for straight, 41 grooves 42 embedded; User present position can be calculated in conjunction with local latitude, time and projection angle etc.; Be marked with the time scale of 24 hours systems at dumb card 4 subscript, adjustment makes northern aligning with the north of dumb card 4 on compass 3 be positioned at same straight line, learns the time of first summary at that time by observing sunlight projected position.

As shown in Figure 2, described base 1 also includes magnifier 5 and level crossing 6, and described magnifier 5 can be articulated with base 1 with horizontally rotating, and described level crossing 6 is positioned at the below of magnifier 5; Namely magnifier 5 can be used as magnifier and uses and can also use as condenser; Described level crossing 6 can be used as mirror and also can be used as catoptron.

Above-described, be only preferred embodiment of the present utility model, the scope that the utility model is implemented can not be limited, every equalization change of doing according to the utility model claim and decoration, all should still belong in scope that the utility model contains.
