In order to solve the defects of the technical scheme, the utility model aims to provide an adjustable opening and closing door of a compass cover.
The aim of the utility model is achieved by the following technical scheme.
The utility model provides an adjustable switch door of compass cover, includes compass cover body, cover door and switch door, cover door rotates to be installed on the compass cover body be provided with semicircular window on the cover door, the switch door rotates to be installed in the window department of cover door, adjusts the opening angle size between switch door and the window through rotatory switch door, and then adapts to different light environment, and the convenient staff can accurate clear observation magnetism compass's scale.
In the technical scheme, the other end of the cover door is provided with the convex tongue, so that the cover door can be opened more conveniently.
In the technical scheme, the inner surface of the cover door is provided with the arc-shaped slide rail along the top arc of the semicircular window, the switch door is semicircular, the bottom center position of the switch door is arranged on the cover door through the rotating shaft, and the edge of the switch door is slidably embedded in the arc-shaped slide rail.
In the technical scheme, the arc-shaped slideway is fixedly arranged on the inner surface of the cover door through rivets.
In the technical scheme, the handle is arranged on the switch door, so that a user can rotate the switch door conveniently.
In the above technical scheme, the handle is located the bottom one side position of switch door, and the corresponding bottom both sides position at window sets up the recess to in making the handle can put into the recess, when the handle was put into one of them recess, the switch door was closed the window completely, when the handle was put into another recess, the switch door was opened the window completely.
The utility model has the advantages and beneficial effects that:
according to the compass, the sliding way is arranged on the inner surface of the cover door of the compass cover, the opening and closing door is arranged, and the window is arranged on the cover door, so that the opening angle between the opening and closing door and the window can be adjusted by rotating the opening and closing door, different light environments are further adapted, staff can conveniently and accurately and clearly observe scales of the magnetic compass in the compass cover, and the magnetic compass is not required to be seen by partially opening the cover door, so that the compass is convenient, quick and safe.

Other relevant drawings may be made by those of ordinary skill in the art from the above figures without undue burden.
Detailed Description
The technical scheme of the utility model is further described below with reference to specific embodiments.
Example 1
As shown in fig. 1-2, an adjustable opening and closing door of a compass cover comprises a compass cover body 1, a cover door 2 and an opening and closing door 3, wherein the cover door 2 is rotatably installed on the compass cover body 1, specifically speaking, one end of the cover door 2 is rotatably connected with the compass cover body 1 through a rotating shaft, the other end of the cover door 2 is provided with a protruding tongue 4, so that the cover door 2 is more convenient to open, a semicircular window 6 is arranged on the cover door 2, the opening and closing door 3 is rotatably installed at the window 6 of the cover door 2, the opening angle between the opening and closing door 3 and the window 6 is adjusted through rotating the opening and closing door 3, different light environments are further adapted, and staff can accurately and clearly observe scales of a magnetic compass conveniently. For example, when the sun shines strongly on the compass cover in noon, the window can be opened at a small angle, so that staff can clearly observe the scales of the magnetic compass, and when the sun shines, the opening angle can be properly enlarged.
Further, an arc-shaped slide way 5 is arranged on the inner surface of the cover door 2 along the top arc of the semicircular window 6 (in this embodiment, the arc-shaped slide way 5 is fixedly installed on the inner surface of the cover door 2 through rivets), the switch door 3 is semicircular, the bottom center position of the switch door 3 is installed on the cover door 2 through a rotating shaft 9, and the edge of the switch door 3 is slidably embedded in the arc-shaped slide way 5, so that the switch door 3 can rotate around the rotating shaft 9.
Example 2
On the basis of the embodiment 1, a handle 8 is arranged on the switch door 3, so that a user can conveniently rotate the switch door 3.
Further, the handle 8 is located at a bottom side of the opening and closing door 3, and corresponding grooves 7 are provided at two sides of the bottom of the semicircular window 6, so that the handle 8 can be placed in the grooves 7, when the handle 8 is placed in one of the grooves 7, the opening and closing door 3 completely closes the window, and when the handle 8 is placed in the other groove 7, the opening and closing door 3 completely opens the window.
Spatially relative terms, such as "upper," "lower," "left," "right," and the like, may be used in the embodiments for ease of description to describe one element or feature's relationship to another element or feature's illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.
