As shown, the fixing bracket 1900 is installed on the top of the shelf fixing part 1420, and an insertion space 1911 is formed so that the detachable and fastening part 1820 of the rotating and detachable part 1800 can be inserted. (1910) and a rotation receiving unit (1920) disposed at the lower end of the inner insertion space (1911) of the fixed body and accommodated so that the rotation control unit (1830) is rotatable.

That is, the rotation and detachment part 1800 is detachably fastened to the fixing bracket 1900 so as to be rotatable, the buffer part 1700 is coupled to the upper part of the rotation and detachment part 1800, and the terminal on the upper part of the buffer part 1700 The shelf portion 1410 is coupled.

A guide groove 1912 is formed in the center of the insertion space 1911 along its periphery. The above-described rotation guide portion 1824 is accommodated in the guide groove 1912, and accordingly, the detachable body portion 1810 can rotate in a certain track without being separated from the fixing bracket 1900.

On the other hand, a plurality of locking grooves 1921 are recessed along the circumference of the rotation receiving portion 1920 on the inner surface thereof. The first sphere (1834) and the second sphere (1838) are accommodated in the locking groove (1921) to have a fixed fixing force.

In other words, as the detachable body 1810 rotates, the detachable rotation shaft 1812 rotates, and the rotation control unit 1830 at the lower end of the rotation control unit 1830 also rotates, and the first sphere 1834 and the second sphere 1838 are caught When accommodated in the groove (1921), it temporarily has a slight fixing force, and after the first sphere (1834) and the second sphere (1838) ride over the locking groove (1921), it will be accommodated in another locking groove (1921). At this time, the user can clearly recognize whether the user rotates or not by delivering the feeling of'clicking' to the user.

If, when the angle adjustment of the geodetic survey part 1100 is completed and there is no need to rotate the detachable body part 1810 anymore, a current flows through the electromagnet part 1835 to flow the first slider 1833 and the second slider 1837. ) To be as hard as a single rod, and accordingly, the first sphere 1834 and the second sphere 1838 are fixed in a state accommodated in the locking groove 1921, so that the detachable body portion 1810 does not rotate any more. .

Although not shown, the electromagnet unit 1835 may be electrically connected to a general battery, a switch, or the like, so that current may or may not flow depending on the situation.

10 is a view showing an exploded state of each configuration of the windshield according to an embodiment of the present invention, Figure 11 is a cross-sectional view illustrating an exemplary operation of the windshield according to an embodiment of the present invention.

As shown in FIG. 1, a wind extension part 1650 is extended in the horizontal direction on the side of the disk 1424, and a windbreak part 1600 is installed at the end of the wind extension 1650 to measure geodesic from the surrounding wind. It is possible to prevent the part 1100 from shaking excessively.

Specifically, the windshield part 1600 is a wind case 1630 in which the interior is empty and an entry hole 1631 is perforated at the top, and an upper part that is installed so as to be movable up and down in the wind case and protrudes to the outside or can be accommodated inside. The wind body 1610, a plurality of locking protrusions 1611 protruding from the bottom of the front surface of the upper wind body, are disposed in front of the upper wind body and are installed to move up and down so that they can protrude to the outside or be accommodated inside. It includes a lower wind body 1620 and a plurality of rails 1621 which are recessed in the rear surface of the lower wind body and accommodate a plurality of locking projections.

The end of the upper wind body 1610 is connected to the wind rotating motor 1640 and can rotate upward or downward, and a plurality of locking jaws 1611 are accommodated in a plurality of rails 1621 to slide up and down. I can.

As shown, a plurality of locking projections 1611 are formed in a'T' shape so that they are not separated from the rail 1621, and the upper wind body 1610 is in a state where the locking projections 1611 are located at the top of the rail 1621. When is further moved toward the upper part, the lower wind body 1620 is moved upward together with the upper wind body 1610 while the locking jaws 1611 are caught by the rail 1621.

Conversely, when the upper wind body 1610 is moved toward the lower side, the lower wind body 1620 is also moved toward the lower side by its own weight, and the upper wind body 1611 is located at the bottom end of the rail 1621. When the 1610 is further moved toward the lower side, the lower wind body 1620 is accommodated in a state that overlaps and overlaps in front of the upper wind body 1610.

The present invention is configured by dividing the upper wind body 1610 and the lower wind body 1620 as described above, and configuring the lower wind body 1620 to move upward according to the upward movement of the upper wind body 1610 At the same time, the effect of preventing wind entry can be maximized.

In addition, the present invention can freely adjust the degree of spreading of the upper wind body 1610 and the lower wind body 1620 in consideration of the speed of the wind.

On the other hand, in the upper wind body 1610, a plurality of vent holes 1612 are disposed to be spaced apart in the transverse direction, and a plurality of air grooves 1613 are spaced apart between the plurality of vent holes 1612.

The plurality of ventilation holes 1612 are formed in a long elliptical shape in the longitudinal direction, and some wind passes through the upper wind body 1610 and naturally flows backward, so that when strong wind occurs, the upper wind body 1610 It has the effect of preventing breakage or excessive vibration.

The plurality of air grooves 1613 are formed in the shape of a'g' shape with a high center portion and low both ends, and four air grooves 1613 spaced apart in the longitudinal direction form a set. The plurality of air grooves 1613 guide and flow the wind hitting the upper wind body 1610 in the direction of the vent hole 1612.

The present invention described above is not limited by the above-described embodiments and the accompanying drawings, and it is common in the technical field to which the present invention pertains that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention.
