Description

Technical Field

[0001] The invention belongs to the technical field of automatic unwinding wires, and in particular relates to an automatic unwinding wire device for garden construction measurement. Background Art

[0002] In the planning process of garden construction, it is generally necessary to lay out the lines first, that is, to determine some characteristic points and characteristic lines by pulling lines from specific points, and then use markers such as lime or pile driving to mark the positions.

[0003] There are roughly two types of winding devices used for paying out the line. One is equipped with a winding spring inside, which has the function of automatic winding. However, as the pulling distance becomes farther and farther, the elastic force of the winding spring also increases. Since the internal space is limited, this winding device is not suitable for long-distance paying out the line. The other is without a winding spring inside, and is released and wound up by hand cranking. This type of winding and releasing generally requires at least two people to operate together, and the labor cost is higher. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a long-distance automatic unwinding device that is easy to use, quick to operate by one person, and can be operated by one person; in order to save effort and avoid pulling the fixed base plate out of the soil, the multi-roller clamping assembly needs to be as smooth as possible when released, thereby reducing the resistance of the flexible tape measure when passing through the multi-roller clamping assembly, and when winding, the multi-roller clamping assembly needs to form a certain resistance to the flexible tape measure, so as to ensure that the flexible tape measure inside the hollow shell is tensioned; and if a more complex tensioning mechanism with adjustable resistance is set at the multi-roller clamping assembly, the structure of the entire device will become complicated and redundant, which is not conducive to the control of cost and failure rate in use; in order to overcome this technical contradiction, the present invention creatively proposes an ingenious structure combining an active unwinding mechanism and an adaptive sliding drive mechanism, through the one-way transmission characteristics of the winding ratchet assembly and the arc protrusions 1 and 2 that can undergo elastic deformation, when winding, the flexible tape measure and the multi-roller clamping assembly are relatively rotated by "asynchronous motion", thereby providing the friction required for tensioning.

[0005] Moreover, in order to prevent the winding main shaft from rotating freely during transportation and placement, the present invention also creatively proposes an adaptive sliding drive mechanism, which automatically completes the locking and unlocking of the locking turntable through the steps of installing and disassembling the fixed base plate, without the need for extra steps, truly achieving "non-sensing locking" and "non-sensing unlocking"; the supporting roller can also make the rotation of the rotating platform smoother.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes an automatic unwinding device for garden construction measurement, including an active unwinding mechanism, an adaptive sliding drive mechanism, a base fixing mechanism and an automatic opening and closing unlocking mechanism, wherein the adaptive sliding drive mechanism is arranged at one end of the active unwinding mechanism, the active unwinding mechanism is arranged on the base fixing mechanism, and the automatic opening and closing unlocking mechanism is arranged on the side of the active unwinding mechanism.

[0007] Furthermore, the active unwinding mechanism includes a hollow shell, a winding assembly and a winding ratchet assembly, the hollow shell is provided with an outer shell base, the hollow shell is arranged on the base fixing mechanism through the outer shell base, the winding assembly is rotatably arranged in the hollow shell, and the winding ratchet assembly is arranged on the winding assembly.

[0008] Through the one-way transmission of the winding ratchet assembly, the technical effect of "the winding assembly rotates passively when releasing and actively rotates when winding" can be achieved.

[0009] Preferably, the winding assembly comprises a winding spindle, a winding disk and a flexible tape measure, the winding spindle is rotatably arranged in a hollow shell, the winding disk is clamped on the winding spindle, the flexible tape measure is wound on the winding disk, and the two sides of the flexible tape measure are respectively provided with a smooth surface and a rough surface.

[0010] The contact between the smooth surface and the friction roller allows relative sliding between the smooth surface and the friction roller, thereby achieving tensioning of the flexible tape measure inside the hollow shell without causing damage to the flexible tape measure. The stable rolling contact between the rough surface and the driving roller allows auxiliary release through the rolling of the driving roller during release.

[0012] The first ratchet and the second ratchet can only rotate relative to each other in one direction. The active and driven relationship between the first ratchet and the second ratchet will be switched during winding and releasing. The one-way transmission of the first ratchet and the second ratchet can better match the friction roller and the driving roller.

[0013] Furthermore, the adaptive sliding drive mechanism includes a multi-roller clamping assembly, a winding transmission mechanism, a release ratchet assembly and a motor drive assembly, the multi-roller clamping assembly is arranged on the hollow shell, the winding transmission mechanism is arranged on the multi-roller clamping assembly, the release ratchet assembly is arranged on the multi-roller clamping assembly, and the motor drive assembly is arranged on the multi-roller clamping assembly.

[0014] Through the transmission structure of the adaptive sliding drive mechanism and the winding ratchet assembly, a variety of different but ingenious technical effects can be achieved in different driving modes.

[0015] Preferably, the multi-roller clamping assembly comprises a roller mounting frame, a friction roller, a driving roller and a cleaning roller, the roller mounting frame is fixedly connected to a hollow shell, the friction roller, the driving roller and the cleaning roller are all rotatably arranged in the roller mounting frame, the flexible tape measure is located between the friction roller and the driving roller, and the flexible tape measure is located between the friction roller and the cleaning roller.

[0016] As a further preferred embodiment of the present invention, the winding transmission mechanism includes a transmission pulley, a transmission belt, a driving gear and a driven gear, the transmission pulley is fixedly connected to the shaft of the friction roller, the transmission belt is arranged between the transmission pulley and the second ratchet, the driving gear is fixedly connected to the shaft of the friction roller, the driven gear is fixedly connected to the shaft of the cleaning roller, and the driving gear and the driven gear are meshed for transmission.

[0017] Through the cooperation of the winding ratchet assembly, the multi-roller clamping assembly and the winding transmission mechanism, the flexible tape measure can be actively released for long-distance measurement conditions through the active rotation of the driving roller during release. During this process, the friction roller, the driving roller and the cleaning roller are in rolling contact with the flexible tape measure and there is no resistance that hinders the movement of the flexible tape measure, thereby achieving smooth release of the flexible tape measure; and when winding, since the linear speed of the flexible tape measure is greater than the linear speed of the friction roller, the relative friction and slippage between the friction roller and the smooth surface can maintain the tension of the flexible tape measure, thereby improving the tightness of the flexible tape measure when winding. At this time, the cooperation between the driven bevel gear and the arc protrusion 2 allows the third ratchet and the fourth ratchet to rotate relative to each other, thereby further improving the tension of the flexible tape measure.

[0018] Preferably, the release ratchet assembly includes a third ratchet and a fourth ratchet, the third ratchet is fixedly connected to the shaft of the driving roller, the third ratchet is provided with an arc protrusion 1, the fourth ratchet is rotatably arranged on the third ratchet, the fourth ratchet is provided with an arc protrusion 2 matching the arc protrusion 1, and the outer wall of the fourth ratchet is also provided with teeth meshing with the driving gear.

[0020] The driving motor can be driven by remote control, so that a single person can easily complete long-distance line laying.

[0021] Furthermore, the base fixing mechanism includes a horizontal rotation component and an inductive lifting component, the horizontal rotation component includes a fixed base plate and a rotating platform, the bottom of the fixed base plate is provided with ground nails, the rotating platform is rotatably arranged in the fixed base plate, the hollow shell is fixedly connected to the rotating platform through the outer shell base, and the inductive lifting component is lifted and slidably arranged on the fixed base plate.

[0022] Through the free rotation of the rotating platform, when the position and direction of the operator change, the opening of the hollow shell can automatically follow and adjust, thereby ensuring the accuracy of the flexible tape measure and the smoothness of winding and releasing.

[0023] Preferably, the inductive lifting component includes a lifting top support ring and a return spring, the lifting top support ring is evenly distributed with sliding columns in a ring shape, the lifting top support ring is slidably engaged with the sliding columns on the fixed bottom plate, the bottom of the sliding columns is provided with an arc-shaped bottom plate, the return spring is sleeved on the outside of the sliding columns, and the return spring is arranged between the lifting top support ring and the fixed bottom plate.

[0024] When the fixed base plate is inserted into the soil, the lifting top support ring will be lifted, thereby unlocking the automatic opening and closing unlocking mechanism. When unlocked, although there will be a certain resistance to the rotation of the winding main shaft due to the contact between the tooth groove slope and the locking rod slope, it will not get stuck.

[0025] Furthermore, the automatic opening and closing unlocking mechanism includes a lifting guide assembly and a supporting assembly, and the supporting assembly is arranged on the lifting guide assembly.

[0026] Preferably, the lifting guide assembly includes a locking turntable, a lifting guide sleeve and a lifting locking rod, the locking turntable is fixedly connected to the winding main shaft, the inner ring of the locking turntable is evenly distributed with locking tooth grooves, the edge position of the locking tooth groove is provided with a tooth groove slope portion, the lifting guide sleeve is fixedly connected to the outer shell base, the lifting locking rod is snap-fitted and slidably arranged in the lifting guide sleeve, the top of the lifting locking rod is provided with a locking pin, and the edge position of the locking pin is provided with a locking rod slope portion matching the tooth groove slope portion.

[0027] As a further preferred embodiment of the present invention, the top support assembly includes a spring base plate, a locking spring and a top support roller, the spring base plate is fixedly connected to the lifting locking rod, the locking spring is arranged between the spring base plate and the lifting guide sleeve, the top support roller is arranged at the bottom of the lifting locking rod, and the top support roller is in rolling contact with the lifting top support ring.

[0028] Through the elastic force of the locking spring, the lifting locking rod always has a tendency to slide downward. Therefore, when the base fixing mechanism is not fixed in the soil, the lifting locking rod can prevent the winding assembly from rotating freely during transportation and storage through its own locking. After the base fixing mechanism is fixed in the soil, the lifting locking rod can apply a certain rotational resistance to the winding spindle through its own jumping.

[0029] The beneficial effects achieved by the present invention using the above structure are as follows:

[0030] (1) Through the one-way transmission of the winding ratchet assembly, the technical effect of "the winding assembly rotates passively when releasing and actively rotates when winding" can be achieved.

[0031] (2) The contact between the smooth surface and the friction roller allows the smooth surface and the friction roller to slide relative to each other, thereby achieving tensioning of the flexible tape measure inside the hollow shell without causing damage to the flexible tape measure. The stable rolling contact between the rough surface and the driving roller allows auxiliary release through the rolling of the driving roller during release.

[0032] (3) The first ratchet wheel and the second ratchet wheel can only rotate relative to each other in one direction. The active and passive relationship between the first ratchet wheel and the second ratchet wheel will be switched during winding and releasing. The one-way transmission of the first ratchet wheel and the second ratchet wheel can better match the friction roller and the driving roller.

[0033] (4) Through the transmission structure of the adaptive sliding drive mechanism and the winding ratchet assembly, a variety of different but ingenious technical effects can be achieved in different driving modes.

[0034] (5) Through the cooperation of the winding ratchet assembly, the multi-roller clamping assembly and the winding transmission mechanism, the flexible tape measure can be actively released for long-distance measurement conditions through the active rotation of the driving roller during release. During this process, the friction roller, the driving roller and the cleaning roller are in rolling contact with the flexible tape measure and there is no resistance that hinders the movement of the flexible tape measure, thereby achieving smooth release of the flexible tape measure; and when winding, since the linear speed of the flexible tape measure is greater than the linear speed of the friction roller, the relative friction and slip between the friction roller and the smooth surface can maintain the tension of the flexible tape measure, thereby improving the tightness of the flexible tape measure when winding. At this time, the cooperation between the driven bevel gear and the arc protrusion 2 allows the third ratchet and the fourth ratchet to rotate relative to each other, thereby further improving the tension of the flexible tape measure.

[0035] (6) The drive motor can be driven by remote control, so that a single person can easily complete long-distance line laying.

[0036] (7) Through the free rotation of the rotating platform, when the position and direction of the operator change, the opening of the hollow shell can automatically follow and adjust, thereby ensuring the accuracy of the flexible tape measure and the smoothness of winding and releasing.

[0037] (8) When the fixed base plate is inserted into the soil, the lifting top support ring will be lifted, thereby unlocking the automatic opening and closing unlocking mechanism. When unlocked, although there will be a certain resistance to the rotation of the winding main shaft due to the contact between the tooth groove slope and the locking rod slope, it will not get stuck.

[0038] (9) Due to the elastic force of the locking spring, the lifting locking rod always has a tendency to slide downward. Therefore, when the base fixing mechanism is not fixed in the soil, the lifting locking rod can prevent the winding assembly from rotating freely during transportation and storage through its own locking. After the base fixing mechanism is fixed in the soil, the lifting locking rod can apply a certain rotational resistance to the winding spindle through its own jumping.

They are used to explain the present invention together with the embodiments of the present invention and do not constitute a limitation of the present invention. DETAILED DESCRIPTION

[0054] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0055] like Figure 1 to Figure 12 As shown, the present invention proposes an automatic unwinding device for garden construction measurement, comprising an active unwinding mechanism 1, an adaptive sliding drive mechanism 2, a base fixing mechanism 3 and an automatic opening and closing unlocking mechanism 4, wherein the adaptive sliding drive mechanism 2 is arranged at one end of the active unwinding mechanism 1, the active unwinding mechanism 1 is arranged on the base fixing mechanism 3, and the automatic opening and closing unlocking mechanism 4 is arranged on the side of the active unwinding mechanism 1.

[0056] The base fixing mechanism 3 includes a horizontal rotating component 37 and an inductive lifting component 38. The horizontal rotating component 37 includes a fixed bottom plate 39 and a rotating platform 40. A ground nail 43 is provided at the bottom of the fixed bottom plate 39. The rotating platform 40 is rotatably arranged in the fixed bottom plate 39. The hollow shell 5 is fixedly connected to the rotating platform 40 through the outer shell base 8. The inductive lifting component 38 is lifted and slidably arranged on the fixed bottom plate 39.

[0057] Through the free rotation of the rotating platform 40 , when the position and direction of the operator change, the opening of the hollow shell 5 can be automatically adjusted accordingly, thereby ensuring the accuracy of the flexible tape measure 11 and the smoothness of winding and releasing.

[0058] The inductive lifting component 38 includes a lifting top support ring 41 and a reset spring 42. The lifting top support ring 41 is evenly distributed with sliding columns 44 in a ring shape. The lifting top support ring 41 is slidably engaged with the sliding columns 44 on the fixed bottom plate 39. An arc-shaped bottom plate 45 is provided at the bottom of the sliding columns 44. The reset spring 42 is sleeved on the outside of the sliding columns 44. The reset spring 42 is arranged between the lifting top support ring 41 and the fixed bottom plate 39.

[0059] When the fixed base plate 39 is inserted into the soil, the lifting support ring 41 will be lifted, thereby unlocking the automatic opening and closing unlocking mechanism 4. When unlocked, although there will be a certain resistance to the rotation of the winding main shaft 9 due to the contact between the tooth groove slope portion 55 and the locking rod slope portion 57, it will not get stuck.

[0060] The active unwinding mechanism 1 includes a hollow shell 5, a winding assembly 6 and a winding ratchet assembly 7. The hollow shell 5 is provided with an outer shell base 8. The hollow shell 5 is arranged on the base fixing mechanism 3 through the outer shell base 8. The winding assembly 6 is rotatably arranged in the hollow shell 5, and the winding ratchet assembly 7 is arranged on the winding assembly 6.

[0061] Through the one-way transmission of the winding ratchet assembly 7, the technical effect of "the winding assembly 6 rotates passively during release and actively rotates during rewinding" can be achieved.

[0062] The winding assembly 6 includes a winding spindle 9, a winding disk 10 and a flexible tape measure 11. The winding spindle 9 is rotatably arranged in the hollow shell 5. The winding disk 10 is clamped on the winding spindle 9. The flexible tape measure 11 is wound on the winding disk 10. A smooth surface 14 and a rough surface 15 are respectively provided on both sides of the flexible tape measure 11.

[0063] The contact between the smooth surface 14 and the friction roller 23 allows the smooth surface 14 and the friction roller 23 to slide relative to each other, thereby achieving tensioning of the flexible tape measure 11 inside the hollow shell 5 without causing damage to the flexible tape measure 11. The stable rolling contact between the rough surface 15 and the driving roller 24 allows auxiliary release through the rolling of the driving roller 24 during release.

[0064] The winding ratchet assembly 7 includes a first ratchet 12 and a second ratchet 13. The first ratchet 12 is fixedly connected to the winding spindle 9. The second ratchet 13 is rotatably arranged on the first ratchet 12. The outer diameter of the second ratchet 13 is smaller than the outer diameter of the winding disk 10. The first ratchet 12 is provided with a first ratchet tooth 16. The second ratchet 13 is provided with a second ratchet tooth 17 corresponding to the first ratchet tooth 16.

[0065] The first ratchet 12 and the second ratchet 13 can only rotate relative to each other in one direction. The active and driven relationship between the first ratchet 12 and the second ratchet 13 will be switched during winding and releasing. The one-way transmission of the first ratchet 12 and the second ratchet 13 can better match the friction roller 23 and the driving roller 24.

[0066] The automatic opening and closing unlocking mechanism 4 includes a lifting guide assembly 46 and a supporting assembly 47 , and the supporting assembly 47 is arranged on the lifting guide assembly 46 .

[0067] The lifting guide assembly 46 includes a locking turntable 48, a lifting guide sleeve 49 and a lifting locking rod 50. The locking turntable 48 is fixedly connected to the winding main shaft 9. The inner ring of the locking turntable 48 is evenly distributed with locking tooth grooves 54. The edge position of the locking tooth groove 54 is provided with a tooth groove slope portion 55. The lifting guide sleeve 49 is fixedly connected to the shell base 8. The lifting locking rod 50 is slidably engaged in the lifting guide sleeve 49. A locking pin 56 is provided on the top of the lifting locking rod 50. The edge position of the locking pin 56 is provided with a locking rod slope portion 57 matching the tooth groove slope portion 55.

[0068] The top support assembly 47 includes a spring base plate 51, a locking spring 52 and a top support roller 53. The spring base plate 51 is fixedly connected to the lifting locking rod 50. The locking spring 52 is arranged between the spring base plate 51 and the lifting guide sleeve 49. The top support roller 53 is arranged at the bottom of the lifting locking rod 50. The top support roller 53 and the lifting top support ring 41 are in rolling contact.

[0069] Due to the elastic force of the locking spring 52, the lifting locking rod 50 always has a tendency to slide downward. Therefore, when the base fixing mechanism 3 is not fixed in the soil, the lifting locking rod 50 can prevent the winding assembly 6 from rotating freely during transportation and storage through its own locking. After the base fixing mechanism 3 is fixed in the soil, the lifting locking rod 50 can apply a certain rotational resistance to the winding spindle 9 through its own jumping.

[0070] The adaptive sliding drive mechanism 2 includes a multi-roller clamping assembly 18, a winding transmission mechanism 19, a release ratchet assembly 20 and a motor drive assembly 21. The multi-roller clamping assembly 18 is arranged on the hollow shell 5, the winding transmission mechanism 19 is arranged on the multi-roller clamping assembly 18, the release ratchet assembly 20 is arranged on the multi-roller clamping assembly 18, and the motor drive assembly 21 is arranged on the multi-roller clamping assembly 18.

[0071] Through the transmission structure of the adaptive sliding drive mechanism 2 and the winding ratchet assembly 7, a variety of different but ingenious technical effects can be achieved in different driving modes.

[0072] The multi-roller clamping assembly 18 includes a roller mounting frame 22, a friction roller 23, a driving roller 24 and a cleaning roller 25. The roller mounting frame 22 is fixedly connected to the hollow shell 5. The friction roller 23, the driving roller 24 and the cleaning roller 25 are all rotatably arranged in the roller mounting frame 22. The flexible measuring tape 11 is located between the friction roller 23 and the driving roller 24. The flexible measuring tape 11 is located between the friction roller 23 and the cleaning roller 25.

[0073] The winding transmission mechanism 19 includes a transmission pulley 26, a transmission belt 27, a driving gear 28 and a driven gear 29. The transmission pulley 26 is fixedly connected to the shaft of the friction roller 23. The transmission belt 27 is arranged between the transmission pulley 26 and the second ratchet 13. The driving gear 28 is fixedly connected to the shaft of the friction roller 23. The driven gear 29 is fixedly connected to the shaft of the cleaning roller 25. The driving gear 28 and the driven gear 29 are meshed for transmission.

[0074] Through the cooperation of the winding ratchet assembly 7, the multi-roller clamping assembly 18 and the winding transmission mechanism 19, the flexible tape measure 11 can be actively released for long-distance measurement conditions through the active rotation of the driving roller 24 during release. During this process, the friction roller 23, the driving roller 24 and the cleaning roller 25 are in rolling contact with the flexible tape measure 11 and there is no resistance that hinders the movement of the flexible tape measure 11, thereby achieving smooth release of the flexible tape measure 11; and when winding, since the linear speed of the flexible tape measure 11 is greater than the linear speed of the friction roller 23, the relative friction and slippage between the friction roller 23 and the smooth surface 14 can maintain the tension of the flexible tape measure 11, thereby improving the tightness of the flexible tape measure 11 when winding. At this time, the cooperation between the driven bevel gear 34 and the arc protrusion 2 36 allows the third ratchet 30 and the fourth ratchet 31 to rotate relative to each other, thereby further improving the tension of the flexible tape measure 11.

[0075] The release ratchet assembly 20 includes a third ratchet 30 and a fourth ratchet 31. The third ratchet 30 is fixedly connected to the shaft of the driving roller 24. The third ratchet 30 is provided with an arc protrusion 1 35. The fourth ratchet 31 is rotatably arranged on the third ratchet 30. The fourth ratchet 31 is provided with an arc protrusion 2 36 matching the arc protrusion 1 35. The outer wall of the fourth ratchet 31 is also provided with teeth meshing with the driving gear 28.

[0076] The motor drive assembly 21 includes a drive motor 32, a driving bevel gear 33 and a driven bevel gear 34. The drive motor 32 is fixedly connected to the roller mounting frame 22, the driving bevel gear 33 is fixedly connected to the output shaft of the drive motor 32, and the driven bevel gear 34 is fixedly connected to the shaft of the friction roller 23. The driving bevel gear 33 and the driven bevel gear 34 are meshed and connected.

[0077] The driving motor 32 can be driven by remote control, so that a single person can easily complete long-distance line release.

[0078] like Fig.13 As shown, point A is located on the friction roller 23, point B is located on the second ratchet 13, and point C is located on the outer ring of the flexible tape measure 11;

[0079] When released, the friction roller 23 and the flexible tape measure 11 are in rolling contact, and the linear speeds of points A, B and C are the same. However, since the rotation radius of point C is greater than that of point B, the rotation angular speed of point B is greater than that of point C. At this time, through the cooperation of the first ratchet 16 and the second ratchet 17, the second ratchet 13 can be allowed to rotate relative to the first ratchet 12 at an angular speed greater than that of the first ratchet 12.

[0080] When winding, the linear speeds of point A and point B are still the same, but at this time, due to the driving of the first ratchet 12 by the second ratchet 13, point C and point B rotate synchronously at the same angular speed. Since the rotation radius of point C is greater than the rotation radius of point B, the linear speed of point C is actually greater than the linear speed of point A, so relative sliding occurs between the friction roller 23 and the smooth surface 14; the flexible tape measure 11 moves faster and the friction roller 23 rotates slower, so the flexible tape measure 11 between point A and point B will be tensioned;

[0081] When winding, the rotation speed of the cleaning roller 25 is always synchronized with that of the friction roller 23, and the friction between the cleaning roller 25 and the rough surface 15 is small, so the friction roller 23 and the cleaning roller 25 will slide relative to the flexible tape measure 11. The sliding of the friction roller 23 and the cleaning roller 25 relative to the flexible tape measure 11 can remove dust and debris on the flexible tape measure 11, achieving the purpose of cleaning before winding;

[0082] When winding, the fourth ratchet 31 rotates synchronously with the friction roller 23, and since the friction between the rough surface 15 and the driving roller 24 is relatively large, the two maintain a relatively stable rolling contact, so the rotation speed of the third ratchet 30 corresponds to the flexible tape measure 11; at this time, the deformation of the arc protrusion 1 35 and the arc protrusion 2 36 allows relative rotation between the third ratchet 30 and the fourth ratchet 31.

[0083] When in use, the user first needs to insert the ground nail 43 into the soil at the designated position. As the ground nail 43 is inserted into the ground, the ground will contact and push the arc bottom plate 45 upward. During this process, the lifting support ring 41 also overcomes the elastic force of the return spring 42 and gradually moves away from the fixed bottom plate 39.

[0084] When the rotating platform 40 is lifted, the lifting locking rod 50 will also be lifted. At this time, the locking pin 56 will slide out of the locking tooth groove 54 to unlock the winding assembly 6. After that, when the winding assembly 6 rotates, the contact between the tooth groove slope portion 55 and the locking rod slope portion 57 will generate rotation resistance, but then the lifting locking rod 50 will continue to rotate after being pushed open, and will not cause jamming.

[0085] The surface of the friction roller 23 is distributed with fine hairs, which can not only avoid damaging the smooth surface 14 when sliding relative to the smooth surface 14, but also provide a certain friction force. The surface of the cleaning roller 25 is distributed with relatively coarse hairs, which can extend the life of the cleaning roller when sliding relative to the rough surface 15. The friction between the driving roller 24 and the rough surface 15 is relatively large, which is a relatively stable rolling contact relationship.

[0086] When releasing, the driving motor 32 can be powered off, and the flexible tape measure 11 can be pulled out and released by the operator manually. During this process, the friction roller 23, the driving roller 24 and the cleaning roller 25 all rotate following the movement of the flexible tape measure 11. At this time, the friction roller 23, the driving roller 24 and the cleaning roller 25 are in rolling contact with the flexible tape measure 11.

[0087] At this time, the winding spindle 9 rotates as the flexible tape measure 11 is released. Due to the existence of the automatic opening and closing unlocking mechanism 4, the winding spindle 9 will have a certain rotation resistance, so the flexible tape measure 11 will be tightened inside the hollow shell 5, and the outside will also be tightened due to the pulling of the operator;

[0088] During the release process, the second ratchet 13 rotates through the transmission of the transmission belt 27. Since the outer diameter of the second ratchet 13 is smaller than the outer diameter of the winding disk 10, and the first ratchet 12 is fixed to the winding spindle 9, the rotation speed of the first ratchet 12 will be lower than the rotation speed of the second ratchet 13. Through the cooperation of the first ratchet 16 and the second ratchet 17, the second ratchet 13 can be allowed to rotate at a rotation speed greater than the first ratchet 12.

[0089] When releasing, if the distance is too far, the drive motor 32 can also be started by the remote control. The drive motor 32 rotates the friction roller 23 through the engagement of the active bevel gear 33 and the driven bevel gear 34. The friction roller 23 rotates the drive roller 24 through the engagement of the active gear 28 and the fourth ratchet 31. Due to the rolling contact between the drive roller 24 and the rough surface 15, the rotation of the drive roller 24 can actively release the flexible tape measure 11, reduce the pulling force of the operator, and also reduce the risk of pulling the fixed base plate 39 out of the soil.

[0090] After the layout is completed, you can draw lines on the ground or determine some special points based on the layout to facilitate subsequent construction. You can also provide feedback on the layout distance. The distance measurement methods that can be selected are as follows:

[0091] Since the driving roller 24 is always in rolling contact with the rough surface 15, the sensor installed on the driving roller 24 can sense the direction and number of rotations of the driving roller 24, thereby transmitting the length of the flexible tape 11 pulled out to the operator's remote control for numerical feedback.

[0092] When winding, the drive motor 32 is started in reverse by the remote control. When the drive motor 32 rotates in reverse, it will drive the friction roller 23, the drive roller 24 and the cleaning roller 25 to rotate in the opposite direction to that when releasing; and through the transmission of the drive pulley 26 and the drive belt 27, the second ratchet wheel 13 will also rotate synchronously;

[0093] When the second ratchet 13 rotates, due to the cooperation of the first ratchet 16 and the second ratchet 17, the first ratchet 12 will rotate synchronously with the second ratchet 13. Since the outer diameter of the second ratchet 13 is smaller than the outer diameter of the winding disk 10, the actual winding speed of the flexible tape 11 will be greater than the speed at which the friction roller 23 and the driving roller 24 convey the flexible tape 11 inward. At this time, the friction roller 23 will slip relative to the smooth surface 14 and the cleaning roller 25 will slip relative to the rough surface 15, thereby cleaning the flexible tape 11 before winding; and since the rotation speeds of the friction roller 23, the driving roller 24 and the cleaning roller 25 cannot keep up with the movement speed of the flexible tape 11 when the winding disk 10 rotates, the flexible tape 11 is tensioned before winding so that it can be wound more tightly.

[0094] Since the driving roller 24 and the rough surface 15 are in rolling contact, but the fourth ratchet wheel 31 is kept in mesh with the driving gear 28, the third ratchet wheel 30 and the fourth ratchet wheel 31 need to be allowed to rotate relative to each other by deformation of the arc protrusion 1 35 and the arc protrusion 2 36 during winding;

[0095] When winding, the relative rotational resistance between the third ratchet 30 and the fourth ratchet 31, as well as the rotational resistance of the locking turntable 48, can be overcome by the driving force of the friction roller 23; when the friction roller 23 assists in releasing, it is necessary to ensure that the arc protrusion 1 35 and the arc protrusion 2 36 can provide a transmission force greater than the rotational resistance of the locking turntable 48.

[0096] After the complete winding is completed, the fixed base plate 39 can be pulled out of the soil. At this time, the lifting top support ring 41 will be close to the fixed base plate 39 under the elastic force of the reset spring 42, and the locking pin 56 will also be inserted into the locking tooth groove 54 to complete the locking of the locking turntable 48.

[0097] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
