Abstract
The utility model provides a take compass can adjust map of direction according to magnetic declination. The utility model discloses a tradition map sets up the compass on take compass can adjust map of direction according to magnetic declination to openly attaches a table that can show the main city in whole world magnetic declination value at take compass can adjust map of direction according to magnetic declination with the version. The utility model discloses utilize the combination of compass and map and confirm geographical north pole direction according to magnetic declination differentiation value, so the adjustment map put the direction, provide more accurate assistance and orientation for the user. The utility model discloses the structure is exquisite simple and easy, lets the map user can discern the direction fast and accurately to more the science and accurately bring into play the map should have the function.
Description
Technical field:
This utility model relates to a kind of culture and tourism supplies, particularly relates to a kind of for precisely determining direction, the band compass finding destination the energy map according to magnetic declination adjustment direction.
Background technology
People are when using map, although all knowing rules such as " up north and down south, left west and right easts ", but owing in unfamiliar place, its direction is difficult to know, and cannot judge that the biggest error will be brought to the use of map in direction exactly, someone may be with compass once in a while, it is intended to adjust with compass travel direction, but due to generally magnetic north pole and north geographic pole misaligned, mostly there is the existence of magnetic declination various places, and magnetic biasing angle value everywhere differs.The biggest difficulty and error is brought to the use of map.
Utility model content:
The purpose of this utility model is to overcome the deficiency of existing map function in background technology, there is provided a kind of band compass energy according to the map of magnetic declination adjustment direction, this utility model is by being printed with the subordinate list of reflection various places difference magnetic biasing angle value, and utilize the combination of compass and map, carry out the adjustment of direction in map-making with reference to the size of subordinate list this geomagnetic declination listed and deflection, make people accurately recognize direction, identify direction and utilize map.
The purpose of this utility model is achieved in that band compass the energy map according to magnetic declination adjustment direction, with the table of a city magnetic declination reflecting each major area on figure, described magnetic declination numerical tabular can print with version according to the map body front of magnetic declination adjustment direction at band compass energy.Band compass energy be printed with traditional map (1) according on the map of magnetic declination adjustment direction simultaneously, arrange compass (2), and compass is placed in a disk having graduation mark.
Described band compass also can be according to the map of magnetic declination adjustment direction, and compass is fixed on band compass and can be set to one with band compass energy according to the map of magnetic declination adjustment direction according on the map of magnetic declination adjustment direction.
Described band compass also can be according to the map of magnetic declination adjustment direction, and with the table of a city magnetic declination reflecting each major area on figure, table displayed content is the value of variant area magnetic declination size.
The beneficial effects of the utility model are: this utility model utilizes the combination of compass and map, and different regions magnetic declination numerical tabular is provided, during use, use the direction that compass the magnetic declination calibration map according to location are put, make this direction in map-making more accurate, provide more accurate technical guarantee for map user.This utility model simple in construction science, can make user understand map, science and find direction exactly accurately, in order to preferably play the proper function of map.In order to make compass be firmly sticked on map, compass is fixed on map and is set to one with map, and described magnetic declination numerical tabular can print with version in map body front.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure: 1. map, 2. compass, 3. main cities, whole world magnetic declination divides different table.
Fig. 2 is compass structural representation in this utility model.
Detailed description of the invention
As it is shown in figure 1, band compass the attached map having printed each geomagnetic declination numerical tabular, including traditional map 1 and compass 2, compass 2 glue material sticks on traditional map 1, and compass is positioned in a disk having careful graduation mark.The map body that the global main cities magnetic declination being printed with reflection each geomagnetic declination value on map full figure with compass energy foundation magnetic declination adjustment direction divides different table 3, main cities, whole world magnetic declination to divide different table 3 and band compass also energy foundation magnetic declination adjustment direction can be with version printing.Due to magnetic declination the not always constant in somewhere, but have and change slowly, the present embodiment takes the magnetic biasing angle value of 2014.
Embodiment 1: if user is when BeiJing, China uses this figure, first looking into and taking the magnetic biasing angle value in Beijing (2014) is 5 ° of 54 ' W, when then meaning near Beijing, magnetic north pole is 5 ° of 54 ' E to the west than north geographic pole, and people are when using map, need to ajust map sensing north geographic pole, so the placing direction of this map should be transferred eastwards 5 ° 54 ' after the opposite direction (i.e. magnetic north to) of alignment compass.The rest may be inferred.
The above, preferred embodiment the most of the present utility model, not this utility model is made any pro forma restriction.So any technical staff, without departing under technical solutions of the utility model ambit, may be by the method that is similar to and technical solutions of the utility model are made many possible variations and modification by technology contents, or change the embodiment of equivalent variations into.So all contents without departing from the technical program, the equivalence change made according to shape of the present utility model, structure and principle, all should be covered by protection domain of the present utility model.
Claims (3)
1. a band compass the map of energy foundation magnetic declination adjustment direction, the table of a city magnetic declination reflecting each major area is had on map according to magnetic declination adjustment direction at band compass energy, including traditional map, it is characterized in that: described a kind of band compass also can be printed with traditional map (1) according on the map of magnetic declination adjustment direction, arranging compass (2), compass is placed in a disk having graduation mark.
Band compass the most according to claim 1 also can be according to the map of magnetic declination adjustment direction, it is characterised in that: described compass (2) is fixed on band compass and can be set to one with band compass energy according to the map of magnetic declination adjustment direction according on the map of magnetic declination adjustment direction.
Band compass the most according to claim 1 also can be according to the map of magnetic declination adjustment direction, it is characterized in that: band compass also can be according to the table of the city magnetic declination having an each major area of reflection on the map of magnetic declination adjustment direction, and table displayed content is the value of variant area magnetic declination size.
