Description

Azimuth disk

Technical Field

The utility model relates to a measuring instrument technical field, concretely relates to azimuth disc.

Background

The compass is composed of three parts, namely a seabed, an inner disc and an outer disc, wherein the inner disc is an azimuth disc engraved with azimuth information, and the azimuth information engraved on the traditional azimuth disc is easy to wear and tear due to the fact that the azimuth information is exposed outside for a long time, and azimuth characters are fuzzy or fall off, so that the azimuth information is not clearly represented.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an azimuth dish, the azimuth dish that marks azimuth information is inlayed and is established between last casing and lower casing, and difficult wearing and tearing lead to the typeface fuzzy or drop, cause the azimuth information to show unclear.

The utility model provides an azimuth disc, includes casing, lower casing and azimuth disc, be equipped with the mounting groove on the last casing, the casing can be dismantled down and set up in the mounting groove, the azimuth disc is inlayed and is established between casing and lower casing, be equipped with the sliding tray on the last casing, the sliding tray in have with the telescopic hole of mounting groove intercommunication, sliding lock is equipped with the lock post in the sliding tray, spring coupling is passed through to lock post one end the sliding tray, other end activity are inserted and are established in the telescopic hole, be equipped with the confession on the casing down lock post male lockhole, be equipped with the slip ejector pad on the lock post, the azimuth disc is equipped with the azimuth meter.

Preferably, the upper shell is provided with a positioning column, the lower shell is provided with a first positioning hole for the positioning column to pass through, and the orientation disc is provided with a second positioning hole for the positioning column to pass through.

Preferably, the upper shell, the lower shell and the azimuth disc are all made of transparent PVC plates.

Preferably, the center positions of the upper shell, the lower shell and the azimuth plate are provided with through holes which are mutually communicated.

After the technical scheme is adopted, compared with the background art, the utility model, have following advantage:

the utility model relates to an azimuth disk, the azimuth disk that marks azimuth information is inlayed and is established between last casing and lower casing, and difficult wearing and tearing lead to the typeface to be fuzzy or drop, cause azimuth information to show unclear, and go up the casing and will descend the casing to fix in the mounting groove through slidable lock post, promote the slip ejector pad on the lock post, can take off the casing down, change the azimuth disk.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the present invention, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are all based on the orientation or position relationship shown in the drawings, and are only for convenience of description and simplification of the present invention, but do not indicate or imply that the device or element of the present invention must have a specific orientation, and thus, should not be construed as limiting the present invention.

Examples

Referring to fig. 1 to 3, the present invention discloses an azimuth plate, which comprises an upper casing 1, a lower casing 2 and an azimuth plate (not shown in the figure), wherein the upper casing 1, the lower casing 2 and the azimuth plate are all made of transparent PVC plates. Go up to be equipped with mounting groove 11 on the casing 1, casing 2 can dismantle the setting in mounting groove 11 down, the azimuth dish is inlayed and is established between casing 1 and casing 2 down, upward be equipped with sliding tray 12 on the casing 1, there is the telescopic hole 13 with mounting groove 11 intercommunication in the sliding tray 12, 12 slip locks in the sliding tray are equipped with lock post 14, spring 15 connection sliding tray 12 is passed through to lock post 14 one end, the other end activity is inserted and is established in telescopic hole 13, be equipped with on the casing 2 down and supply lock post 14 male lockhole 21, be equipped with slip ejector pad 16 on the lock post 14, the azimuth dish is equipped with the azimuth table.

The upper shell 1 is provided with a positioning column 17, the lower shell 2 is provided with a first positioning hole 22 for the positioning column 17 to pass through, and the orientation disc is provided with a second positioning hole for the positioning column 14 to pass through. The center positions of the upper shell 1, the lower shell 1 and the azimuth disc are provided with through holes which are communicated with each other, and the azimuth disc of the embodiment is arranged on the sea floor of the compass through the through holes.

During the installation, place the orientation dish earlier in the mounting groove 11 of last casing 1, casing 2 about covering again, prevent orientation dish and casing 2 rotation down through reference column 17, in the lockpost 14 in the sliding tray 12 passes through spring 15 elasticity promotion and inserts casing 2's lockhole 21 down by telescopic hole 13, will descend casing 2 to fix and prevent to drop in mounting groove 11, during the dismantlement, promotes the slip ejector pad 16 on the lockpost 14, can take off casing 2 down, changes the orientation dish.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
