Description

Technical Field

[0001] The utility model relates to the technical field of RTK surveying and setting out, in particular to a protective umbrella used for an RTK surveying instrument. Background Art

[0002] RTK (Real-time kinematic) is a technology based on the global navigation satellite system (GNSS) that uses real-time dynamic carrier phase differential positioning. Its positioning accuracy can reach the centimeter level, and it is easy to operate and does not require line of sight between control points. It has been widely used in the field of construction surveying and layout.

[0003] When performing RTK surveying and staking out, surveyors need to observe the screen of the electronic handheld in real time and perform operations. However, when performing RTK surveying and staking out in the field, due to the sunlight, it is difficult for surveyors to see the screen of the electronic handheld clearly, so it is very easy to make operational errors, resulting in errors in RTK surveying and staking out, causing rework losses.

[0004] Based on this, it is necessary to invent a protective umbrella for RTK surveying instruments to solve the problem that surveyors cannot see the screen of electronic hand-held devices clearly when conducting RTK surveying and setting out in the field. Utility Model Content

[0005] The utility model provides a protective umbrella for an RTK measuring instrument in order to solve the problem that a surveyor cannot see the screen of an electronic hand-held device clearly when performing RTK surveying and setting out in the field.

[0006] The utility model is realized by adopting the following technical solutions:

[0007] A protective umbrella for an RTK surveying instrument, comprising an RTK mobile station antenna, a centering rod and an electronic hand controller, and also comprising a protective umbrella body;

[0008] The bottom of the RTK mobile station antenna is provided with an RTK antenna connection thread hole; the top of the centering rod is extended with a centering rod connection thread rod; the electronic handheld controller is installed on the rod body of the centering rod;

[0009] The protective umbrella body comprises an umbrella surface, an umbrella handle and foldable umbrella ribs; an umbrella handle connecting screw rod is extended from the top of the umbrella handle, and an umbrella handle connecting screw hole is opened at the bottom of the umbrella handle; a mounting base is provided on the upper fixing sleeve of the umbrella handle, and an umbrella rib hinge fixing ring is sleeved on the mounting base, and an external thread is provided on the upper part of the mounting base; an umbrella rib hinge sliding ring is provided on the sliding sleeve of the umbrella handle, and the umbrella rib hinge sliding ring is located below the umbrella rib hinge fixing ring; the umbrella rib hinge sliding ring and the umbrella rib hinge fixing ring are both connected to the center of the foldable umbrella rib;

[0010] A mounting hole is provided at the top of the umbrella surface, and the umbrella handle connecting screw rod passes through the mounting hole and is threadedly connected to the RTK antenna connecting thread hole; the upper part of the mounting base passes through the mounting hole and is screwed with a cymbal-shaped pressure cap nut; the centering rod connecting screw rod is screwed into the umbrella handle connecting thread hole.

[0011] Furthermore, a circular level bubble is installed on the centering rod.

[0012] Furthermore, an umbrella belt is provided at the edge of the outer surface of the umbrella surface; a plurality of bead tails are provided at the edge seam of the umbrella surface, and the tail end of each rib of the folding umbrella rib is inserted into the plurality of bead tails one by one.

[0013] Furthermore, a locking button is installed on the hinged sliding ring of the umbrella ribs; and the upper and lower parts of the umbrella handle are both provided with locking grooves adapted to the locking button.

[0014] Furthermore, the mounting base is fixedly mounted on the umbrella handle by means of fixing screws.

[0015] The utility model has a reasonable and reliable structural design. By adding a protective umbrella body between the RTK mobile station antenna and the centering pole, the sunlight can be effectively shielded, making it convenient for surveyors to observe the screen of the electronic handheld device in real time and operate it in the field. At the same time, the protective umbrella body is installed on the centering pole, and the surveyor does not need to hold the umbrella, which further enhances the practicality.
