DETAILED DESCRIPTION

[0021] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments in the following description are only as examples, and those skilled in the art can think of other obvious modifications.

[0022] Referring to Figures 1-4 As shown in the figure, a kind of map marking device for land space planning, including base plate 1 and expansion plate 11 hinged to one side of base plate 1;

[0023] By the setting of base plate 1 and expansion plate 11, turn over expansion plate 11 to the state of being horizontal with base plate 1, i.e. the surface area of expansion base plate 1, so as to facilitate planning map to be placed on it, provide good horizontal bearing surface for map, facilitate personnel to carry out observation and marking operation on map, otherwise turn over expansion plate 11 to the state of being folded with base plate 1, i.e. facilitate personnel to carry out the whole carrying and transportation.

[0024] Further, referring to Figure 4 As shown in the figure, it is worth mentioning that the side of expansion plate 11 towards base plate 1 is provided with contraction groove 14, and elastic plug-in component is built-in contraction groove 14;

[0025] Elastic plug-in component includes positioning plug 15 slidingly arranged in contraction groove 14 in the shape of right trapezoid and sliding block 16 vertically fixed on positioning plug 15, and sliding groove matched with sliding block 16 is formed on the inner wall of contraction groove 14, spring 17 is fixed between sliding block 16 and one side inner wall of sliding groove, and fixed port 18 corresponding to positioning plug 15 is formed on one side of base plate 1;

[0026] Threaded groove communicated with contraction groove 14 is also formed on the outer wall of expansion plate 11, extrusion screw rod 19 is threadedly connected in threaded groove, one end of extrusion screw rod 19 penetrates into contraction groove 14 and abuts against the oblique edge of positioning plug 15;

[0027] By setting the elastic plug-in part, when the to-be-flipped extension plate 11 is flipped to the state of being horizontal to the base plate 1, the knob is then pressed against the extrusion screw 19, so that the extrusion screw 19 penetrates into the contraction groove 14 under the threaded structure and forms extrusion force against the inclined edge of the positioning plug 15, so that the positioning plug 15 is forced to slide from the inside of the contraction groove 14 into the fixed port 18, thereby locking the base plate 1 and the extension plate 11, ensuring the firmness between the two, and providing a good and reliable placement plane for planning drawings.

[0028] During the process that the positioning plug 15 is forced to penetrate into the fixed port 18, the spring 17 can be synchronously slid in the sliding groove and compressed to deform, so that, by the elastic force of the spring 17, when the extrusion screw 19 is reversely rotated later, the extrusion screw 19 moves upward to reduce the extrusion on the positioning plug 15, the sliding block 16 can carry the positioning plug 15 to reset and contract to the inside of the contraction groove 14 under the elastic force of the spring 17, thereby releasing the fixation between the base plate 1 and the extension plate 11, and facilitating manual flipping and folding of the extension plate 11 and the base plate 1.

[0029] Further, as shown in Figure 2 , it is worth noting that the bottom surface of the base plate 1 is fixedly embedded with a first magnetic strip 12, and the bottom surface of the extension plate 11 is fixedly embedded with a second magnet 13 matched with the first magnetic strip 12;

[0030] When the extension plate 11 is flipped to the state of being folded with the base plate 1, the second magnet 13 is matched with the first magnetic strip 12 and generates attractive force, so that the extension plate 11 can be positioned on the back side of the base plate 1, ensuring the stability of the two in the folded state.

[0031] In addition, as shown in Figure 3 , it is worth noting that the other side edge of the base plate 1 is provided with an opening, and the drawer 2 is slidably arranged in the opening;

[0032] By setting the drawer 2, pulling the drawer 2 out of the opening, it is convenient for manual use of the drawer 2 to place a marker pen or a drawing tool in the inside of the drawer 2, so as to prevent the marker pen or the drawing tool from being lost due to random placement.

[0033] Further, as shown in Figure 3 , it is worth noting that the upper side of the base plate 1 away from the extension plate 11 is transversely provided with a pressing plate 3, and two groups of push-pull components are symmetrically arranged in the inside of the drawer 2;

[0034] By setting the pressing plate 3 and the push-pull component, when the planning drawing is unfolded on the base plate 1, the drawing can be placed under the pressing plate 3 by manual, so that when the drawer 2 is pulled out to take the marker pen or the drawing tool stored in the drawer 2, the pressing plate 3 is quickly attached to the base plate 1 under the action of the push-pull component, and the drawing is compressed, ensuring the firmness of the drawing in land planning.

[0035] Further, referring to Figure 3 As shown in the figure, it is worth mentioning that the push-pull component includes a fixed sheet 5 vertically fixed on the inner wall of the bottom end of the drawer 2, a force slot 6 obliquely opened on the fixed sheet 5, and a sliding column 7 slidingly arranged in the force slot 6, one end of the sliding column 7 is fixed with a pull rod 4, the pull rod 4 vertically upward penetrates the base plate 1 and is fixedly connected with the pressing plate 3;

[0036] When the drawer 2 is pulled out, the sliding column 7 keeps stable sliding relative to the inner side of the force slot 6, so that the sliding column 7 changes the slope of the force slot 6, and then pulls down the pull rod 4, so that the pressing plate 3 is attached to the base plate 1, and the fixing of the planning drawing is realized.

[0037] Further, referring to Figure 1 As shown in the figure, it is worth mentioning that the push-pull component includes a fixed sheet 5 vertically fixed on the inner wall of the bottom end of the drawer 2, a force slot 6 obliquely opened on the fixed sheet 5, and a sliding column 7 slidingly arranged in the force slot 6, one end of the sliding column 7 is fixed with a pull rod 4, the pull rod 4 vertically upward penetrates the base plate 1 and is fixedly connected with the pressing plate 3;

[0038] When the drawer 2 is pulled out, the sliding column 7 keeps stable sliding relative to the inner side of the force slot 6, so that the sliding column 7 changes the slope of the force slot 6, and then pulls down the pull rod 4, so that the pressing plate 3 is attached to the base plate 1, and the fixing of the planning drawing is realized.

[0039] After the drawer 2 is pulled out, the connecting frame 8 carries the bolt 9 to move to a position corresponding to the other positioning port 10, and then the bolt 9 is screwed again, so that the bolt 9 penetrates into the positioning port 10, and the drawer 2 is locked in the same way, ensuring the fixing of the drawer 2 after being pulled out.
