Description

Technical Field

[0001] The utility model relates to the field of drawing surveying and mapping, in particular to a tool plate for drawing surveying and mapping. Background Art

[0002] Topographic surveying refers to the determination, collection and mapping of the shape, size, spatial position and attributes of natural geographical elements or artificial facilities on the surface. It includes two main contents: measurement and mapping. Both measurement and mapping require the use of more tools. Therefore, when conducting field topographic surveying, surveyors need to be equipped with special portable tool tables. After surveying, they need to place the drawings on the tool board for drawing.

[0003] According to a Chinese patent with publication number CN219803477U, a new type of surveying and mapping platform for engineering surveying is disclosed. The utility model is provided with pressure plates around the surveying and mapping platform to compact the drawings to prevent the drawings from being violently flipped by strong winds; and the ends of multiple pressure plates are abutted against each other to intercept the surveying and mapping tools on the surveying and mapping platform to prevent the surveying and mapping tools from falling off the surveying and mapping platform.

[0004] In response to the above-mentioned disclosed patent content, pressure plates are set around to press the drawings to prevent them from being blown away by the wind. However, due to the fixed position of the pressure plates, only larger drawings can be pressed. When smaller drawings need to be pressed, one side of the drawing needs to be moved under the pressure plate so that the pressure plate can only press one side of the drawing, thereby reducing the pressing effect on smaller drawings, causing smaller drawings to be blown away by the wind, thereby reducing the use effect of the tool plate. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a tool plate for drawing surveying and mapping, so as to solve the technical problem that the pressing plate is difficult to press smaller drawings.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tool plate for drawing surveying and mapping, comprising a first plate body, one side of the first plate body is connected to the second plate body by a hinge, the top of the first plate body and the second plate body are both provided with a paper pressing assembly, the paper pressing assembly comprises two first rotating shafts arranged at the top of the first plate body and the second plate body through bearings, and the outer wall of the first rotating shaft is sleeved with a first rotating plate, one end of the first rotating plate is connected to the second rotating plate by the second rotating shaft, a groove is opened inside the second rotating plate, and a return spring is fixed inside the groove, a pressure block extending to the outside of the groove is installed at the bottom end of the return spring, and a pull rod is connected to the top of the pressure block, and a clamping assembly is provided between the first plate body and the second plate body.

[0007] By adopting the above technical solution, when it is necessary to press the drawing, the user can rotate the first rotating plate or the second rotating plate, thereby driving the pressing block to rotate so that the pressing block rotates to the top of the drawing, which is convenient for pressing the drawing later.

[0008] Furthermore, the clamping assembly includes a cavity opened at the lower part of the first plate body and a clamping slot opened on one side of the second plate body, a spring is fixed on one side of the cavity, and a movable block is installed on one end of the spring, one side of the movable block is provided with a clamping block extending into the inside of the clamping slot, and the other side of the movable block is provided with a pull rope.

[0009] By adopting the above technical solution, when the pull rope is pulled, it will drive the movable block to move and squeeze the spring, and the spring will be compressed, and at the same time the movable block will drive the clamping block to move.

[0010] Furthermore, a guide wheel is installed inside the cavity, and one end of the pull rope passes through the guide wheel and penetrates to the outside of the first plate body and is connected to a pull ring.

[0011] By adopting the above technical solution, the setting of the wire wheel can guide the pull rope, and the setting of the pull ring makes it convenient for the subsequent user to pull the pull ring downwards, thereby pulling the pull rope.

[0012] Furthermore, the card block is adapted to the card slot, and the card block is slidably connected to the cavity via a movable block.

[0013] By adopting the above technical solution, when the card block is inserted into the card slot, the second plate body can be limited to prevent the first plate body and the second plate body from rotating.

[0014] Furthermore, the first rotating plate is provided with a first limiting screw extending to the first rotating shaft, the first plate body and the second plate body, and the first rotating plate is also provided with a second limiting screw extending to the second rotating shaft and the second rotating plate.

[0015] By adopting the above technical solution, the user can screw the first limiting screw into the first plate body and the second plate body to limit the first rotating shaft.

[0016] Furthermore, the first limiting screw is threadedly connected to the first rotating shaft, the first plate body and the second plate body, and the second limiting screw is threadedly connected to the second rotating plate and the second rotating shaft.

[0017] By adopting the above technical solution, the first limiting screw can limit the first rotating shaft to prevent the first rotating shaft from rotating at will, thereby improving the stability of the first rotating plate.

[0018] Furthermore, the top end of the pull rod extends to the outside of the second rotating plate and is connected to the pull plate, and the pull rod is located inside the reset spring.

[0019] By adopting the above technical solution, when the user pulls the pull rod upward, the pull rod will drive the pressing block to move upward, so that the pressing block squeezes the return spring.

[0020] Furthermore, the first plate body and the second plate body are rotatably connected via a hinge.

[0021] By adopting the above technical solution, the first plate body and the second plate body can be rotated, and then the first plate body and the second plate body can be folded, thereby reducing the volume of the tool plate and making it easy to carry.

[0022] Furthermore, the first rotating plate is rotatably connected to the first plate body and the second plate body via a first rotating shaft.

[0023] By adopting the above technical solution, the first rotating plate can be rotated through the first rotating shaft, thereby driving the second rotating plate to rotate.

[0024] Furthermore, the bottom of the pressing block contacts the tops of the first plate body and the second plate body, and the pressing block is slidably connected to the groove.

[0025] By adopting the above technical solution, the pressing block can press the drawing to prevent the drawing from being blown by the wind during drawing or viewing, thereby improving the stability of the drawing placement.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] 1. The utility model is provided with a paper pressing assembly. When it is necessary to press the drawing, the user can first screw the bottom end of the first limiting screw into the first rotating shaft, and then screw the bottom end of the second limiting screw into the second rotating shaft. At this time, the user can pull the pull rod upward to move the pressing block upward, and at the same time rotate the first rotating plate or the second rotating plate, thereby driving the pressing block to rotate, so that the pressing block rotates to the top of the drawing. When it rotates to the edge of the drawing, the user releases the pull rod, and the reset spring stretches and pushes the pressing block downward, so that the pressing block presses the drawing. Since the first rotating plate and the second rotating plate can both rotate, the position of the pressing block can be adjusted, so that the edge of the drawings of smaller sizes can be pressed by the pressing block, thereby improving the applicability of the paper pressing assembly, avoiding the situation that only drawings of larger sizes can be pressed, and improving the use effect of the tool plate;

[0028] 2. The utility model is provided with a clamping assembly. When the tool plate needs to be carried, the user can pull the pull ring downward, the pull ring pulls the drawstring, the drawstring pulls the movable block, and then drives the clamping block to move, so that the clamping block is moved out from the inside of the clamping slot. At this time, the clamping block no longer limits the second plate body, and then the second plate body or the first plate body can be rotated to fold the first plate body and the second plate body, thereby reducing the overall volume of the tool plate, making it easier for users to carry the tool plate and improving the carrying effect of the tool plate.

One end of the pull rope 406 passes through the wire wheel 407 and extends to the outside of the first plate body 1 and is connected to a pull ring 408. The setting of the wire wheel 407 can guide the pull rope 406, and the setting of the pull ring 408 is convenient for subsequent users to pull the pull ring 408 downward, thereby pulling the pull rope 406.

[0046] See also Figure 2-Figure 6 A block 402 extending into the slot 403 is provided on one side of the movable block 404, and the block 402 is adapted to the slot 403. The block 402 is slidably connected to the cavity 401 through the movable block 404. When the block 402 is inserted into the slot 403, the second plate body 5 can be limited to prevent the first plate body 1 and the second plate body 5 from rotating. A pull rope 406 is provided on the other side of the movable block 404. When the pull rope 406 is pulled, it will drive the movable block 404 to move and squeeze the spring 405, and the spring 405 will be compressed, and at the same time, the movable block 404 will drive the block 402 to move.

[0047] The working principle of the utility model is as follows: first, when drawing is required on the board, the user can place the drawing on the first board 1 and the second board 5, and then screw the bottom end of the first limiting screw 302 into the first rotating shaft 301, so that the first limiting screw 302 no longer limits the first rotating shaft 301, and then screw the bottom end of the second limiting screw 305 into the second rotating shaft 304. At this time, the user can pull the pull rod 309 upward to move the pressing block 310 upward, and at the same time rotate the first The rotating plate 303 or the second rotating plate 306 drives the pressing block 310 to rotate, so that the pressing block 310 rotates to the top of the drawing. When the pressing block 310 rotates to the edge of the drawing, the user releases the pull rod 309. At this time, the return spring 308 stretches and pushes the pressing block 310 downward, so that the pressing block 310 presses the drawing. Since the first rotating plate 303 and the second rotating plate 306 can both rotate, the position of the pressing block 310 can be adjusted, so that the edge of the drawing with a smaller size can be pressed by the pressing block 310.

[0048] When the tool plate needs to be carried, the user can first screw the first limiting screw 302 into the plate body to limit the first rotating plate 303, and then screw the second limiting screw 305 into the second rotating plate 306 to limit the second rotating plate 306, and then pull the pull ring 408 downward, the pull ring 408 pulls the pull rope 406, and the pull rope 406 pulls the movable block 404, and then drives the card block 402 to move, so that the card block 402 moves out of the card slot 403. At this time, the card block 402 no longer limits the second plate body 5, and then the second plate body 5 or the first plate body 1 can be rotated to fold the first plate body 1 and the second plate body 5, while reducing the overall volume of the tool plate, making it easier for the user to carry the tool plate.
