Description

Technical Field

[0001] This utility model relates to the field of soil profile measurement technology, and in particular to a novel profile survey ruler. Background Technology

[0002] A profile survey ruler is a tool used to measure and record the characteristics of soil or geological profiles. It is widely used in agriculture, geological exploration, environmental science, and land management. Traditional profile survey rulers are usually made of wood or plastic, with simple scales and limited functions, which cannot meet the needs of modern scientific research for high precision, portability, and multifunctionality. With the increasing demand for measurement, new profile survey rulers have gradually introduced waterproof and corrosion-resistant materials, optimized scale accuracy, and combined with portable design to adapt to complex field environments.

[0003] The applicant discovered through a search that a Chinese patent discloses "A Novel Profile Survey Ruler" with publication (announcement) number "CN220568000U". This patent facilitates marking readings on the ruler box, which is beneficial for intuitively reflecting information such as the thickness of the topsoil layer. However, the ruler box of this device has a fixed size and cannot be adjusted according to different soil layer heights, resulting in the inability to accurately measure soil profiles at different depths. It also cannot be flexibly adjusted according to different environments and needs, limiting the scope of use of the equipment and failing to meet diverse measurement requirements. Therefore, we propose a novel profile survey ruler. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of profile survey ruler to solve the problems mentioned in the background art, such as the fixed size of the ruler box, which cannot be adjusted according to different soil layer heights, resulting in the inability to accurately measure soil profiles at different depths, the inability to flexibly adjust according to different environments and needs, the limitation of the scope of use of the equipment, and the inability to meet diverse measurement needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel profile survey ruler, comprising a fixed structure, a movable structure, and a retractable structure. The movable structure is installed at the top of the fixed structure, and the retractable structure is installed inside the fixed structure. The fixed structure includes a winding box and a fixed box. The movable structure includes a movable box, a first slide rail, and a first slide groove. The movable box is slidably connected to the first slide groove via the first slide rail. A fastening bolt is threaded onto the fixed box. A second display groove and a second limiting groove are provided on one side of the movable box. Second slide rails are fixedly installed on the movable box and the fixed box, respectively. A second slide groove is provided on the inner wall of the fixed box. The second slide rail is slidably connected to the second slide groove. A limiting bolt and a pointer are installed on the second slide rail via a slider.

[0006] As a preferred embodiment, the fixing box is fixedly installed on the top of the winding box and is internally interconnected. A fixing nail is fixedly installed on one side of the fixing box, and a first display groove and a first limiting groove are respectively provided on the side of the fixing box away from the fixing nail.

[0007] As a preferred embodiment, the first slide rails are fixedly installed at both ends of the movable box, the first slide groove is formed on the inner wall of the fixed box, and the fastening bolts limit the movable box.

[0008] As a preferred embodiment, the second display slot is aligned with the first display slot, the second limiting slot is aligned with the first limiting slot, the slider is slidably mounted on the second slide rail, the limiting bolt is threaded onto the slider, the limiting bolt limits the slider, and the pointer is fixedly mounted on one side of the slider.

[0009] As a preferred embodiment, the take-up and unwinding structure includes a rotating shaft and a take-up drum. The rotating shaft is rotatably mounted inside the take-up box, with one end of the rotating shaft extending through the take-up box to the outside of the take-up box. The take-up drum is fixedly mounted on the rotating shaft, and a handle is fixedly mounted on one end of the rotating shaft. A fixing seat is fixedly mounted on the take-up box, and a screw is threaded onto the fixing seat. A limiting plate is rotatably mounted on the bottom end of the screw, and a rubber pad is fixedly mounted inside the limiting plate.

[0010] As a preferred embodiment, a pull rod is slidably installed in the first and second limiting grooves, a measuring tape is wound on the winding drum, the free end of the measuring tape is fixedly connected to the pull rod, and a magnet is fixedly installed at the top of the interior of the movable box.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the designed movable structure, the movable box slides within the fixed box via the first slide rail, and is then limited by the fastening bolts. This allows for easy adjustment based on soil layer height, adapting to different soil profile measurement needs. Users can quickly adjust the position of the movable box to ensure accurate measurement of soil layers at various depths. Because the movable box can be precisely adjusted to the required depth and limited by the fastening bolts, the consistency of measurement depth is ensured for each measurement, avoiding human error and improving data accuracy. Due to the design of the first slide rail and fastening bolts, the components of the movable box are easy to disassemble and replace, facilitating daily maintenance and cleaning, and increasing the service life of the equipment.

[0013] 2. Through the designed take-up and take-down structure, the pull rod drives the free end of the measuring tape on the take-up drum to move, so that the free end of the measuring tape is attracted by the magnet on the top of the movable box, which prevents the free end of the measuring tape from loosening or slipping, thus improving the measurement accuracy. At the same time, the screw rotates in the fixed seat, thereby driving the limit plate and rubber pad to limit the rotating shaft on the take-up drum, fixing the take-up drum and thus fixing the measuring tape. This effectively fixes the take-up drum when the measuring tape is stretched, preventing the take-up drum from springing back or loosening on its own, maintaining the stability of the measuring tape during use, reducing human interference, and avoiding measurement errors or equipment damage caused by improper manual operation.

[0023] Example 1:

[0024] Please see the appendix Figure 1 - Appendix Figure 6 A novel profile survey ruler includes a fixed structure 1, a movable structure 2, and a retractable structure 3. The movable structure 2 is installed at the top of the fixed structure 1, and the retractable structure 3 is installed inside the fixed structure 1. The fixed structure 1 includes a winding box 11 and a fixing box 12. The fixing box 12 is fixedly installed at the top of the winding box 11 and is internally interconnected. A fixing nail 13 is fixedly installed on one side of the fixing box 12. A first display groove 14 and a first limiting groove 15 are respectively provided on the side of the fixing box 12 away from the fixing nail 13. The first limiting groove 15 is on one side of the first display groove 14.

[0025] The movable structure 2 includes a movable box 201, a first slide rail 202, and a first slide groove 203. The first slide rail 202 is fixedly installed at both ends of the movable box 201. The first slide groove 203 is formed on the inner wall of the fixed box 12. The movable box 201 is slidably connected to the first slide rail 202 and the first slide groove 203. A fastening bolt 204 is threaded onto the fixed box 12, and the fastening bolt 204 limits the movable box 201. A second display groove 205 and a second limiting groove 206 are provided on one side of the movable box 201. The second display groove 205 is connected to the first slide groove 206. The display slot 14 is aligned with the first limiting slot 15. The second limiting slot 206 is aligned with the first limiting slot 15. The second slide rail 207 is fixedly installed on the movable box 201 and the fixed box 12 on the same side as the second display slot 205. The inner wall of the fixed box 12 is provided with a second sliding groove 209. The second slide rail 207 is slidably connected to the second sliding groove 209. The slider 208 is slidably installed on the second slide rail 207. The limiting bolt 210 is threaded on the slider 208 and limits the slider 208. The pointer 211 is fixedly installed on one side of the slider 208.

[0026] Specifically, by setting the movable structure 2, the movable box 201 slides in the fixed box 12 via the first slide rail 202 and is limited by the fastening bolt 204, which facilitates adjustment according to the soil layer height and ensures accurate measurement of soil layers at different depths. This design improves the consistency of measurement depth, reduces human error, and enhances data accuracy. At the same time, the movable box 201 is easy to disassemble and replace, which facilitates daily maintenance and cleaning and extends the service life of the equipment.

[0027] Example 2:

[0028] Please see the appendix Figure 1 - Appendix Figure 7 The take-up and take-down structure 3 includes a rotating shaft 31 and a take-up drum 32. The rotating shaft 31 is rotatably installed inside the take-up box 11. One end of the rotating shaft 31 extends through the take-up box 11 to the outside of the take-up box 11. The take-up drum 32 is fixedly installed on the rotating shaft 31. A handle 33 is fixedly installed at the end of the rotating shaft 31 that extends out of the take-up box 11. A fixing seat 34 is fixedly installed on the take-up box 11 on the same side as the handle 33. A screw 35 is threaded onto the fixing seat 34. A limiting plate 36 is rotatably installed at the bottom end of the screw 35. A rubber pad 37 is fixedly installed inside the limiting plate 36. A pull rod 38 is slidably installed in the first limiting groove 15. A measuring tape is wound on the take-up drum 32. The free end of the measuring tape is fixedly connected to the pull rod 38. A magnet 39 is fixedly installed at the top of the interior of the movable box 201. The magnet 39 attracts the free end of the measuring tape.

[0029] Specifically, through the retraction structure 3, the pull rod 38 drives the free end of the measuring tape to move and is attracted by the magnet 39 on the top of the movable box 201, preventing the free end from loosening and improving measurement accuracy. The screw 35 rotates to drive the limit plate 36 and the rubber pad 37 to fix the winding drum 32, preventing rebound or loosening and ensuring the stability of the measuring tape. This design reduces human interference and avoids measurement errors or equipment damage caused by improper operation.

[0030] Working principle of this utility model: This utility model is a new type of profile survey ruler. The fixing nail 13 is inserted into the soil layer, and the fixing box 12 is adjusted to be vertical and horizontal. According to the height of the soil layer, the movable box 201 is pulled. The movable box 201 slides in the first slide groove 203 through the first slide rail 202, thereby raising the height of the movable box 201. Then, the fastening bolt 204 is rotated. The fastening bolt 204 limits the movable box 201, thereby fixing the movable box 201 in the fixing box 12. Then, the pull rod 38 is pulled upward. The pull rod 38 drives the free end of the measuring tape to move upward, so that the winding drum 32 drives the rotating shaft 31 to rotate in the winding box 11. The free end of the measuring tape is attracted by the magnet 39, thereby fixing the measuring tape. The scale on the measuring tape is displayed in the first display groove 14 and the second display groove 205.

[0031] Rotating the screw 35 causes it to move threadedly within the fixed seat 34, thereby lowering the limiting plate 36. The limiting plate 36 then moves the rubber pad 37 to further limit the rotation shaft 31. The rubber pad 37 increases the friction with the rotation shaft 31, improving the limiting effect. Limiting the rotation shaft 31 thus limits the winding drum 32, fixing the measuring tape's position. Based on the soil thickness, the sliding block 208 slides on the second slide rail 207, causing the pointer 211 to move. Pointer 211 will point to the scale of the measuring tape. When pointer 211 moves to the position corresponding to the soil layer thickness, the limiting bolt 210 is rotated to limit slider 208 on the second slide rail 207, thereby fixing slider 208 and facilitating the reading of the number indicated by pointer 211. When it is necessary to retract the measuring tape, screw 35 is rotated so that the limiting plate 36 and rubber pad 37 no longer limit the rotating shaft 31. Handle 33 is rotated, and handle 33 drives the winding drum 32 to rotate through the rotating shaft 31, thereby retracting the measuring tape.

[0032] 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.
