Description

Technical Field

[0001] This utility model relates to the field of positioning devices for extracting tabular data, and more particularly to a positioning device for extracting tabular data. Background Technology

[0002] The data extraction and positioning device is a specialized instrument designed for accurately locating geological data from various media, such as borehole records, stratigraphic profiles, and core analysis data tables, during geological exploration. It is compatible with different media, including paper exploration reports, electronic geological terminal screens in the field, and core sampling labels. By locating the row and column coordinates of the corresponding geological data (such as stratigraphic thickness, lithology number, borehole depth, and other key information fields), it avoids data misalignment caused by media displacement during scanning or acquisition. Its core function is to ensure the accuracy of extracting key information such as stratigraphic layering data, ore grade parameters, and hydrogeological observations from geological tables, providing reliable data positioning support for geological reserve calculations, geological hazard assessments, and other tasks, thereby improving the efficiency and accuracy of geological data processing.

[0003] However, current positioning devices for extracting table data have the following drawbacks: First, the fixed structure is not detachable, making it impossible to replace it with a different type of fixture to suit different scenarios, resulting in insufficient flexibility and difficulty in meeting diverse usage needs. Second, the range of compatibility is limited, failing to be compatible with table carriers of different thicknesses and sizes, lacking versatility, and unable to meet the positioning needs of diverse carriers. In response to this technical problem, this application proposes a positioning device for extracting tabular data. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a positioning device for extracting tabular data. This device aims to facilitate the disassembly of the fixed structure, allowing for the replacement of different types of fixed structures as needed, thereby improving the flexibility of the positioning device and enabling it to position carriers of different thicknesses and sizes, thus enhancing its versatility.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A positioning device for extracting tabular data includes a base plate with two grooves on its top side. Two bases are slidably connected between the two grooves, and two slide blocks are slidably connected to the top side of each base. A positioning component and a fixing component are provided on the top side of each slide block. The positioning component includes a fixing plate located on the top side of the slide block. A rotating rod is rotatably connected inside the fixing plate. An eccentric wheel for positioning the tabular data carrier is fixedly connected to the right end of the rotating rod. An adjustment component for adjusting the distance between the edge of the eccentric wheel and the carrier is provided inside the fixing plate. A rubber ring for reducing damage to the carrier is fixedly connected to the outer wall of the eccentric wheel. The positioning component also includes a fixing strip located on the top side of the slide block. An arc-shaped plate for positioning the carrier is rotatably connected to the right side of the fixing strip. The right side of the fixing strip is connected to the arc-shaped plate via a torsion spring.

[0006] Furthermore, the fixing assembly includes a slot formed on the top side of the slide block, and the top sides of both the fixing plate and the fixing strip are fixedly connected with a plug that matches the slot, the plug being inserted into the inside of the slot.

[0007] Furthermore, a rotating plate is rotatably connected to one side of the slide, and the slide and the rotating plate are connected by a torsion spring. A protruding strip is fixedly connected to one side of the rotating plate, and a slot is provided on one side of both the fixed plate and the fixed strip, with the protruding strip engaging inside the slot.

[0008] Furthermore, the adjusting assembly includes a threaded rod rotatably connected inside the fixed plate, the outer wall of the threaded rod being threaded with a rack, and the rack being slidably connected inside the fixed plate.

[0009] Furthermore, a gear is fixedly connected to one end of the rotating rod, and the rack and gear mesh with each other. A third knob is rotatably connected to the top side of the fixed plate through a damping shaft, and the top end of the threaded rod is fixedly connected inside the third knob.

[0010] Furthermore, a first bidirectional screw is rotatably connected inside the slide groove on the left side, the bottom side of the base is threadedly connected to the outer wall of the first bidirectional screw, and a first knob is rotatably connected to the front side of the base plate through a damping shaft. The front end of the first bidirectional screw is fixedly connected to the inside of the first knob.

[0011] Furthermore, a second bidirectional screw is rotatably connected inside the base, and the bottom side of the slide is threadedly connected to the outer wall of the second bidirectional screw. A second knob is rotatably connected to the left side of the base via a damping shaft, and the left end of the second bidirectional screw is fixedly connected inside the second knob.

[0012] This utility model has the following beneficial effects: 1. In this utility model, by inserting the plug rod into the slot and using a torsion spring to make the rotating plate abut against one side of the fixing plate or fixing strip, the protrusion is engaged in the slot, thereby fixing the fixing plate or fixing strip to the slide. This makes the fixing structure easy to disassemble, allowing for the replacement of different types of fixing structures as needed, thus improving the flexibility of the positioning device.

[0013] 2. In this utility model, rotating the third knob causes the threaded rod to rotate, which in turn drives the rack to move up and down. This, in turn, causes the gear to rotate the rotating rod, which in turn causes the eccentric wheel to rotate. This adjusts the distance between the edge of the eccentric wheel and the carrier, allowing the device to position carriers of different thicknesses and sizes, thus improving the device's versatility.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-3 One embodiment of this utility model provides a positioning device for extracting tabular data, including a base plate 1. Two sliding grooves are formed on the top side of the base plate 1, and two bases 2 are slidably connected between the two sliding grooves. Two sliding blocks 9 are slidably connected to the top side of each base 2. Figure 3 and Figure 6 A fixing plate 5 is provided on the top side of the slide 9. A rotating rod 17 is rotatably connected inside the fixing plate 5. An eccentric wheel 6 for positioning the table data carrier is fixedly connected to the right end of the rotating rod 17. A rubber ring 16 for reducing damage to the carrier is fixedly connected to the outer wall of the eccentric wheel 6. The eccentric wheel 6 presses down on the table carrier, such as paper or a screen, thereby pressing down the edge of the carrier and preventing the carrier from shifting when extracting data. The rubber ring 16 also reduces the damage caused to the carrier by the eccentric wheel 6. A fixing strip 11 is also provided on the top side of the slide 9. An arc-shaped plate 12 for positioning the carrier is rotatably connected to the right side of the fixing strip 11. The right side of the fixing strip 11 is connected to the arc-shaped plate 12 by a torsion spring. The two bases 2 are connected by a torsion spring, which makes the bottom side of the arc plate 12 contact the carrier, so that the arc plate 12 clamps the carrier on the base plate 1. The bottom side of the arc plate 12 is provided with a rubber strip to reduce damage to the carrier. The inside of the left sliding groove is rotatably connected to the first bidirectional screw 3. The bottom side of the base 2 is threaded to the outer wall of the first bidirectional screw 3. The front side of the base plate 1 is rotatably connected to the first knob 4 through a damping shaft. The front end of the first bidirectional screw 3 is fixedly connected to the inside of the first knob 4. By rotating the first knob 4, the first bidirectional screw 3 is rotated, so that the two bases 2 slide in opposite directions, thereby adjusting the distance between the two bases 2, so that the device can fix carriers of different sizes. The base 2 is internally rotatably connected to a second bidirectional screw 7. The bottom side of the slide 9 is threadedly connected to the outer wall of the second bidirectional screw 7. The left side of the base 2 is rotatably connected to a second knob 8 via a damping shaft. The left end of the second bidirectional screw 7 is fixedly connected to the inside of the second knob 8. By rotating the second knob 8, the second bidirectional screw 7 is rotated, causing the second bidirectional screw 7 to drive the two slides 9 to slide in relative or opposite directions, thereby adjusting the distance between the two slides 9. This allows the device to fix carriers of different sizes, further improving the versatility of the device.

[0018] Reference Figure 4 and Figure 5The top side of the slide block 9 has a slot. The top sides of the fixing plate 5 and the fixing strip 11 are fixedly connected with a plug rod 13 that matches the slot. The plug rod 13 is inserted into the inside of the slot. A rotating plate 14 is rotatably connected to one side of the slide block 9. The slide block 9 and the rotating plate 14 are connected by a torsion spring. A protruding strip 15 is fixedly connected to one side of the rotating plate 14. A slot is opened on one side of the fixing plate 5 and the fixing strip 11. The protruding strip 15 is engaged in the slot. By inserting the plug rod 13 into the slot and using the torsion spring to make the rotating plate 14 abut against one side of the fixing plate 5 or the fixing strip 11, the protruding strip 15 is engaged in the slot, thereby fixing the fixing plate 5 or the fixing strip 11 to the slide block 9. This makes the fixing structure easy to disassemble, so that different types of fixing structures can be replaced as needed, thereby improving the flexibility of the positioning device.

[0019] Reference Figure 6 A threaded rod 20 is rotatably connected inside the fixed plate 5. A rack 19 is threadedly connected to the outer wall of the threaded rod 20. The rack 19 is slidably connected inside the fixed plate 5. A gear 18 is fixedly connected to one end of the rotating rod 17. The rack 19 and the gear 18 mesh with each other. A third knob 10 is rotatably connected to the top side of the fixed plate 5 through a damping shaft. The top end of the threaded rod 20 is fixedly connected inside the third knob 10. By rotating the third knob 10, the threaded rod 20 is rotated, which drives the rack 19 to move up and down. This, in turn, drives the rotating rod 17 to rotate through the gear 18. The rotating rod 17 then drives the eccentric wheel 6 to rotate, thereby adjusting the distance between the edge of the eccentric wheel 6 and the carrier. This allows the device to position carriers of different thicknesses and sizes, improving the versatility of the device.

[0020] Working principle: First, place the carrier containing tabular data on the base plate 1. Then, rotate the first knob 4 to rotate the first bidirectional screw 3, causing the two bases 2 to slide in opposite directions, bringing them closer to the sides of the carrier and ultimately clamping them. Next, rotate the second knob 8 to rotate the second bidirectional screw 7, driving the two slides 9 to slide in opposite or relative directions, moving the four slides 9 to the four corners of the carrier. When using the eccentric wheel 6 for positioning, rotate the third knob 10 to rotate the threaded rod 20. The rotation causes the threaded rod 20 to drive the rack 19 to move up and down, which in turn drives the rotating rod 17 to rotate via the gear 18. This causes the rotating rod 17 to rotate along with the eccentric wheel 6, bringing the edge of the eccentric wheel 6 closer to the surface of the carrier and ultimately clamping the carrier. When using the arc plate 12 for positioning, it needs to be moved and turned on the slide 9 to disengage it from the bottom side to prevent the carrier from blocking it. Then, the arc plate 12 is released so that its bottom side abuts against the carrier to complete the positioning of the carrier. After that, the tabular data on the carrier can be extracted by scanning or other methods.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
