Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In the present invention, it is noted that relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.

When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Furthermore, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like are used herein to indicate orientations or positional relationships based on the drawings, and are used for convenience in describing the present invention, but do not indicate or imply that the device or element so referred to must have this particular orientation, be operated in a particular orientation configuration, and not be construed as limiting the present invention.

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments thereof.

Referring to fig. 1-3, a marker post with a placing rack for surveying and mapping comprises a placing rack 10 and a marker post 40.

As shown in fig. 1-2, the placing rack 10 is in a shape of a round cake, three screw holes 13 are axially formed in the placing rack, and the center of a spatial circle where the three screw holes 13 are located coincides with the center of the placing rack 10.

Each screw hole 13 is internally threaded and matched with a screw rod 22, the lower end of each screw rod 22 is connected with the spine piece 23 through a bearing (the bearing is not shown), so that the screw rods 22 and the spine piece 23 can rotate relatively, the handle 21 is fixed at the upper end of each screw rod 22, and the handle 21 is preferably made larger in size, so that the female can use the tool conveniently. The handle 21, the screw 22 and the spike 23 together form the adjustment lever 20.

The inside of the placing rack 10 is a sealed cavity, a water inlet 11 communicated with the cavity is arranged on the upper surface of the placing rack 10, and a water outlet 12 communicated with the cavity is arranged on the side surface of the placing rack 10.

The upper surface of rack 10 is fixed with connecting seat 30, and connecting seat 30 is equipped with upper portion open-ended and connects chamber 31, and connecting seat 30 is perpendicular with rack 10, and the lower part of sighting rod 40 is for inserting the section, inserts the section and inserts and connect chamber 31, accomplishes rack 10 and sighting rod 40's fixing.

The level 14 is fixed on the upper surface of the placing frame 10.

In order to reduce the difficulty of the insertion section entering the connection cavity 31, the opening of the connection cavity 31 is in a shape of a horn with a large top and a small bottom.

In order to keep the pole 40 in a vertical state, two opposite sides of the insertion section of the pole 40 are provided with rails 41, the connection cavity 31 is provided with rail grooves 33 at corresponding positions of the rails 41, and the rails 41 are in interference fit with the rail grooves 33.

The working principle is as follows:

when the water level gauge is required to be used, the placing frame 10 is placed at the position of the fixed marker post 40, the position of the bubble 15 of the level gauge 14 is observed in the three spine pieces 23, and whether the placing frame 10 is located at the horizontal position or not is judged. If yes, inserting the rod for operation; if not, the adjusting and placing rack 10 is positioned at the horizontal position by rotating one or two adjusting rods 20, and then the inserting rod operation is carried out.

When inserting the pole, the inserting section of the pole 40 is inserted into the connecting cavity 31.

If the position of the fixing post 40 is mountain and is not easy to be penetrated, enough water is added at the water inlet 11, and the stability of the placing rack 10 can be kept. However, after the surveying and mapping operation is completed, water is discharged from the water outlet 12, so that the cost for transporting the product of the patent is reduced.

See the prior art for additional details.

While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
