Description

Technical Field

[0001] This application relates to the field of magnetic positioners, and in particular to a magnetic positioner spacing adjustment device. Background Technology

[0002] Magnetic locators are positioning instruments that work based on the principle of magnetic field induction. Their core consists of a magnetic field sensor, a signal processing circuit, and a display device. They can assist in perforation positioning in oil exploration by detecting changes in the magnetic field at the casing coupling, and can also achieve positioning in specific areas by comparing geomagnetic fingerprints. They can also be used in various scenarios such as underground metal pipeline detection, mining exploration, security inspection, and archaeology. With their advantages of non-contact measurement, adaptability to environments with no GPS signal, and ease of operation, they have become a practical tool for positioning in indoor, outdoor, and underground spaces.

[0003] In the existing technology, the adjustment of the spacing of magnetic positioners often requires cumbersome bolts to limit and fix the adjusted magnetic positioners, which results in low flexibility and inconvenience in use.

[0004] A search revealed a Chinese patent document that discloses a locator and a positioning device for installing the locator's magnetic strip (publication number: CN208930052U). However, the following defects still exist: Although the aforementioned locator and positioning device for installing the locator's magnetic strip can be used on-site for major repairs and magnetic strip debugging, and its gap adjustment is convenient, and the installation gap quality is guaranteed and stable, which can improve the on-site installation quality and save time and costs, it still requires cumbersome bolts to limit and fix the adjusted magnetic locator, which results in low flexibility and inconvenience in use. Utility Model Content

[0005] To improve the problems of cumbersome fixing and low flexibility, this application provides a magnetic positioner spacing adjustment device.

[0006] The magnetic locator spacing adjustment device provided in this application adopts the following technical solution: A magnetic locator spacing adjustment device includes a mounting base, an adjustment slide rail is provided inside the top of the mounting base, a plurality of adjustment sliders are slidably connected inside the adjustment slide rail, an inner cavity is provided at the bottom of the adjustment slider, a limit component is installed inside the inner cavity, a magnetic locator placement frame is installed at the top of the adjustment slider, an elastic airbag is installed at one end inside the magnetic locator placement frame, and a clamping component is slidably arranged inside the magnetic locator placement frame.

[0007] By adopting the above technical solution, the adjusting slider moves inside the adjusting slide rail and is quickly limited after adjustment by the limiting component. At the same time, the elastic airbag at one end of the magnetic locator placement frame, together with the clamping component, quickly clamps and limits magnetic locators of different sizes and shapes.

[0008] Preferably, a magnetic absorbing piece is embedded in the bottom of the inner side of the adjusting slide rail, and first limiting protrusions are installed at equal intervals in the corresponding inner side of the adjusting slide rail.

[0009] By adopting the above technical solution, a dual rapid positioning is achieved by using a magnetic absorbing sheet as part of the magnetic attraction limit and in conjunction with the first limiting protrusion.

[0010] Preferably, both ends of the adjusting slider are provided with grooves, and flexible sheets are installed inside the grooves. Second limiting protrusions are installed at equal intervals on the outer wall of one end of the flexible sheet, and the outer wall of the second limiting protrusion abuts against the outer wall of the first limiting protrusion.

[0011] By adopting the above technical solution, the outer wall of the second limiting protrusion abuts against the outer wall of the first limiting protrusion, thereby adjusting the slide rail to self-limit the adjusted slider after the movement is adjusted.

[0012] Preferably, the limiting component includes at least a mounting sleeve and a magnetic block. The mounting sleeve is installed at the top of the inner cavity. A movable sleeve rod is vertically and movably connected to the bottom of the mounting sleeve. A connecting spring is installed at the top of the movable sleeve rod, and the top of the connecting spring is connected to the top of the inner cavity of the mounting sleeve. A magnetic block is installed at the bottom of the movable sleeve rod, and the bottom of the magnetic block is in contact with the top of the magnetic plate.

[0013] By adopting the above technical solution, the limiting component uses magnetic attraction for magnetic limiting, and a dual limiting method is adopted, which allows for rapid adjustment of the spacing.

[0014] Preferably, an actuating piece is installed on the outer wall of the movable sleeve, one end of which passes through the inner cavity and extends to the outside of the adjusting slider.

[0015] By adopting the above technical solution, the movable lever can be moved by using the toggle piece.

[0016] Preferably, the clamping assembly includes at least a mounting plate and silicone protrusions. The mounting plate is slidably connected to the inner top of the magnetic locator placement frame. Two mounting housings are installed on the outer wall of one end of the mounting plate. Connecting springs are symmetrically installed on one end of the inner wall of each mounting housing. Movable blocks are installed on the other end of each connecting spring. Silicone protrusions are installed at equal intervals on one end of each movable block.

[0017] By adopting the above technical solution, the silicone protrusion abuts against the corresponding outer wall of the magnetic locator, while simultaneously pushing the other end of the outer wall of the magnetic locator to abut against the outer wall of the elastic airbag. When the silicone protrusion abuts against the corresponding outer wall of the magnetic locator, due to the squeezing force, the movable block moves into the interior of the mounting housing, squeezing the connecting spring, thus achieving flexible clamping.

[0018] Preferably, the other end of the mounting plate is hinged to one end of the transmission plate via a rotating shaft, and the other end of the transmission plate is hinged to the outer wall of the sliding block via a rotating shaft.

[0019] By adopting the above technical solution, the tilt angle of the transmission plate is changed. As the tilt angle of the transmission plate changes, the mounting plate is pushed to complete the clamping and limiting of the magnetic positioner.

[0020] Preferably, a connecting block is installed at one end of the magnetic locator placement frame. A sliding groove is formed inside the connecting block. A sliding block is vertically slidably connected inside the sliding groove. A connecting screw is rotatably connected between the top and bottom ends of the sliding groove. A transmission screw sleeve is engaged with the outer wall of the connecting screw. The transmission screw sleeve is installed through the inside of the sliding block. An adjusting knob is rotatably connected to the top of the connecting block. The bottom end of the adjusting knob passes through the top of the connecting block and is throttle-connected to the top of the connecting screw.

[0021] By adopting the above technical solution, the connecting screw is rotated by adjusting the knob. Since the connecting screw and the transmission screw sleeve constitute a screw transmission structure, the sliding block inside the sliding groove moves vertically.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This utility model abandons the cumbersome bolt fixing method in the traditional magnetic locator spacing adjustment. By adjusting the sliding cooperation of the slide rail and the adjusting slider, combined with the self-limiting of the first limiting protrusion and the second limiting protrusion, and the magnetic attraction limiting of the magnetic suction plate and the magnetic suction block, a double quick limiting structure is constructed. This design simplifies the spacing adjustment process, allowing the magnetic locator position to be adjusted in time during operation, and ensures the stability after adjustment through double limiting, greatly improving the flexibility of use and the efficiency of operation; 2. In this utility model, the magnetic locator placement frame is equipped with an elastic airbag and a flexible clamping component, which can be adapted to magnetic locators of different sizes and shapes. During the clamping process, the connecting spring can extend and retract with the squeezing force, driving the movable block to flexibly adjust its position. The silicone protrusion can avoid scratching the surface of the magnetic locator, and the inflation structure of the elastic airbag can further buffer the clamping pressure. This flexible clamping design not only enables rapid and stable clamping of various magnetic positioners, but also reduces the limitations of the device's use and effectively protects the appearance and performance of the magnetic positioner.

[0030] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0031] This application discloses a magnetic positioner spacing adjustment device.

[0032] Reference Figure 1 and Figure 2A magnetic locator spacing adjustment device includes a mounting base 1. An adjustment slide rail 2 is provided inside the top of the mounting base 1. A magnetic suction plate 3 is embedded at the bottom of each adjustment slide rail 2. The magnetic suction plate 3 has an S-pole structure. Several adjustment sliders 5 are movably connected inside the top of the adjustment slide rail 2. Grooves are provided at the front and rear ends of each adjustment slider 5, and flexible plates 6 are fixedly connected inside each groove. A second limiting protrusion 7 with a semi-cylindrical structure is fixedly connected at equal intervals to the outer wall of one end of each flexible plate 6. The outer wall of the second limiting protrusion 7 abuts against the outer wall of the first limiting protrusion 4. The first limiting protrusion 4 is fixedly connected at equal intervals to the inner walls of the front and rear ends of the adjustment slide rail 2. The single-sided interference fit between the first limiting protrusion 4 and the second limiting protrusion 7 is designed to be 0.2mm-0.3mm. The thickness of the flexible plate 6 is 2mm.

[0033] During use, the adjusting slider 5 moves within the adjusting slide rail 2 according to the required adjustment distance to meet the magnetic positioner spacing adjustment requirements. After adjustment, the outer wall of the second limiting protrusion 7 abuts against the outer wall of the first limiting protrusion 4, thereby allowing the adjusting slide rail 2 to self-limit the adjusted slider 5. This method eliminates the traditional bolt-type fixing method, making it more flexible and easier to adjust in time during operation. Furthermore, when the first limiting protrusion 4 and the second limiting protrusion 7 press against each other, the flexible sheet 6 undergoes elastic deformation, providing approximately 15N of horizontal resistance and achieving a clear gear feel.

[0034] Reference Figure 3 The mounting base 1 has an inner cavity 8 at its bottom end. A limiting assembly is installed inside the inner cavity 8, including a mounting sleeve 9, a movable sleeve rod 10, a magnetic block 11, a connecting spring 12, and a toggle piece 13. The top end of each inner cavity 8 is fixedly connected to a mounting sleeve 9, and the top end of each mounting sleeve 9 is fixedly connected to a connecting spring 12. The bottom end of the connecting spring 12 is fixedly connected to the top end of the movable sleeve rod 10 inside the bottom end of the mounting sleeve 9. The bottom end of the movable sleeve rod 10 is fixedly connected to a magnetic block 13. The magnetic block 11 is an N-pole structure. The outer wall size of the magnetic block 11 is adapted to the inner wall size of the inner cavity 8. The bottom end of the magnetic block 11 contacts the top end of the magnetic plate 3 and magnetically attracts it. The outer wall of the movable sleeve rod 10 is fixedly connected to the actuating plate 13. One end of the actuating plate 13 passes through the inner cavity 8 and extends to the outside of the adjusting slider 5. The connecting spring 12 is made of 65Mn spring steel with a wire diameter of 1.0mm, a free length of 30mm, and a stiffness coefficient k=2.0N / mm.

[0035] During use, before the adjusting slider 5 moves inside the adjusting slide rail 2, the actuating piece 13 is pushed upwards, causing the actuating piece 13 to drive the movable sleeve 10 to move vertically upwards. This causes the movable sleeve 10 to move into the mounting sleeve 9 and compress the connecting spring 12, thus separating the bottom end of the magnetic block 11 from the top end of the magnetic piece 3 and releasing the magnetic attraction limit. After the adjusting slider 5 has moved and adjusted inside the adjusting slide rail 2, the actuating piece 13 is released, causing the connecting spring 12 to generate a reset potential energy, driving the movable sleeve 10 to move vertically downwards. This causes the bottom end of the magnetic block 11 to contact the top end of the magnetic piece 3, achieving magnetic attraction limit. This dual limit method makes the limit method more convenient during the process of quickly adjusting the spacing, improving both stability and practicality.

[0036] Reference Figure 4 and Figure 5 The top of the adjusting slider 5 is fixedly connected to a magnetic locator placement frame 14 for mounting the magnetic locator. One end of the magnetic locator placement frame 14 is fixedly connected to an elastic airbag 15 with an inflatable structure. The top of the magnetic locator placement frame 14 is movably connected to a clamping assembly, which includes a mounting plate 16, a mounting housing 17, a connecting spring 18, a movable block 19, and silicone protrusions 20. The top of the magnetic locator placement frame 14 is movably connected to the mounting plate 16. Guide plates are fixedly connected to both outer walls of the mounting plate 16. The guide plates pass through the sliding cavity opened inside the magnetic locator placement frame 14. Two mounting housings 17 are fixedly connected to one end of the mounting plate 16. Two connecting springs 18 are fixedly connected to one end of the mounting housing 17. One end of each connecting spring 18 is fixedly connected to one end of the movable block 19, which is movably connected to one end of the mounting housing 17. Three silicone protrusions 20 are fixedly connected to the other end of the movable block 19.

[0037] The magnetic locator to be used is placed on the magnetic locator placement rack 14. The mounting plate 16 is moved towards the magnetic locator, causing the silicone protrusion 20 to abut against the corresponding outer wall of the magnetic locator. At the same time, the other end of the outer wall of the magnetic locator is pushed to abut against the outer wall of the elastic airbag 15. When the silicone protrusion 20 abuts against the corresponding outer wall of the magnetic locator, the squeezing force causes the movable block 19 to move into the mounting housing 17, squeezing the connecting spring 18. This achieves flexible clamping. In use, magnetic locators of different sizes and shapes can be quickly clamped, improving practicality and avoiding the limitations of the device in use.

[0038] Reference Figure 6The other end of the mounting plate 16 is hinged to one end of the transmission plate 21 via a rotating shaft. The other end of the transmission plate 21 is hinged to the outer wall of the sliding block 22 via a rotating shaft. The sliding block 22 is vertically and movably connected inside the sliding groove 23. The sliding groove 23 is opened inside the connecting block 24. The connecting block 24 is fixedly connected to one end of the magnetic positioner placement frame 14. A transmission screw sleeve 26 is fixedly connected through the inside of the sliding block 22. A connecting screw 25 is meshed through the inside of the transmission screw sleeve 26. The connecting screw 25 is rotatably connected between the top and bottom ends inside the sliding groove 23. An adjustment knob 27 is rotatably connected to the top of the connecting block 24. The bottom end of the adjustment knob 27 passes through the top of the connecting block 24 and is connected to the top of the connecting screw 25.

[0039] During use, the adjustment knob 27 is rotated according to the size of the magnetic locator placed inside the magnetic locator placement frame 14. The adjustment knob 27 drives the connecting screw 25 to rotate. Since the connecting screw 25 and the transmission screw sleeve 26 form a screw transmission structure, the sliding block 22 inside the sliding groove 23 moves vertically. After the sliding block 22 moves vertically, the tilt angle of the transmission plate 21 is changed. As the tilt angle of the transmission plate 21 changes, the mounting plate 16 is pushed to complete the clamping and limiting of the magnetic locator.

[0040] The implementation principle of the magnetic locator spacing adjustment device in this application embodiment is as follows: First, according to the size of the magnetic locator placed inside the magnetic locator placement rack 14, the adjustment knob 27 is rotated. The adjustment knob 27 drives the connecting screw 25 to rotate. Since the connecting screw 25 and the transmission screw sleeve 26 form a screw transmission structure, the sliding block 22 inside the sliding groove 23 moves vertically. After the sliding block 22 moves vertically, the tilt angle of the transmission plate 21 is changed. Because the tilt angle of the transmission plate 21 changes, the mounting plate 16 is pushed to complete the clamping and limiting of the magnetic locator. Second, the mounting plate 16 moves towards the magnetic locator, so that the silicone protrusion 20 abuts against the corresponding outer wall of the magnetic locator, and at the same time pushes the other end of the outer wall of the magnetic locator to abut against the outer wall of the elastic airbag pad 15. Then, according to the required adjustment distance, the adjustment slider 5 moves inside the adjustment slide rail 2 to meet the requirements. The magnetic locator spacing adjustment requires that, after adjustment, the outer wall of the second limiting protrusion 7 abuts against the outer wall of the first limiting protrusion 4, thereby adjusting the slide rail 2 to self-limit the adjusted slider 5 after the adjustment; finally, before the adjusted slider 5 moves inside the adjustment slide rail 2, the actuating piece 13 is pushed upward, causing the actuating piece 13 to drive the movable sleeve 10 to move vertically upward, causing the movable sleeve 10 to move into the mounting sleeve 9 and compress the connecting spring 12, thus separating the bottom end of the magnetic block 11 from the top end of the magnetic piece 3 and releasing the magnetic attraction limit. After the adjusted slider 5 moves and adjusts inside the adjustment slide rail 2, the actuating piece 13 is released, thereby causing the connecting spring 12 to generate a reset potential energy, driving the movable sleeve 10 to move vertically downward, thus making the bottom end of the magnetic block 11 contact the top end of the magnetic piece 3, and magnetic attraction limit is achieved through magnetic attraction. In this way, the magnetic locator spacing adjustment device is completed.

Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
