Detailed implementation manners

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-8, the present invention provides a technical solution: a bearing device for a three-axis acceleration sensor, including a bearing seat 1. A plurality of mounting holes 11 are provided on the side wall of the bearing seat 1. The top of the bearing seat 1 is fixedly connected with a mounting seat 12, and a universal ball 13 is arranged on the top of the mounting seat 12. The top of the universal ball 13 is fixedly connected with a support rod 14, and the top of the support rod 14 is connected with a rotating disk 15 through an angle adjusting mechanism 3. The top of the rotating disk 15 is fixedly connected with a three-axis acceleration sensor body 16, and a threaded pipe 17 is fixedly connected to the top of the rotating disk 15. A protective cover 18 is threadedly connected to the side wall of the threaded pipe 17. And a horizontal adjusting mechanism 2 for horizontally adjusting the rotating disk 15 is arranged on the side wall of the mounting seat 12. An exhaust pipe 19 and an intake pipe 26 are fixedly inserted into the bottom of the rotating disk 15. And an opening and closing mechanism 8 is arranged on the side wall of the intake pipe 26. A first one-way valve 20 is arranged in the exhaust pipe 19, and the lower end of the exhaust pipe 19 is fixedly connected with a first connecting pipe 21. The lower end of the first connecting pipe 21 is fixedly connected with a second connecting pipe 22, and a second one-way valve 23 is arranged in the second connecting pipe 22. A fixed pipe 24 is fixedly connected to the side wall of the first connecting pipe 21, and a piston 25 is connected to the fixed pipe 24 through a first pushing mechanism 5, which is convenient for adjusting the orientations of the X-axis, Y-axis, and Z-axis of the three-axis acceleration sensor body 16. While ensuring the detection effect, the adjustment is made more convenient and rapid. At the same time, the protective cover 18 is used for protection. And the air in the protective cover 18 can be automatically discharged to form a negative pressure, which can not only prevent the humid air from affecting the three-axis acceleration sensor body 16, but also hinder the heat conduction, thereby avoiding the influence of high temperature and low temperature on the three-axis acceleration sensor body 16 and ensuring its service effect and life.

[0028] The horizontal adjusting mechanism 2 includes a support frame 201 fixedly connected to the top of the rotating disk 15, and a spirit level 202 is fixedly connected to the top of the support frame 201. A threaded hole 203 is provided on the side wall of the mounting seat 12, and a bolt 204 is threadedly connected in the threaded hole 203. When the three-axis acceleration sensor body 16 needs to be installed, the bearing seat 1 is fixed by fixing bolts. Then, the universal ball 13 is rotated, and the spirit level 202 is observed to level the rotating disk 15 and the three-axis acceleration sensor body 16. After the leveling is completed, the bolt 204 is screwed into the threaded hole 203 and tightened to tightly fix the universal ball 13.

[0029] The angle adjustment mechanism 3 includes a rotating ring 301 rotatably connected to the side wall of the support rod 14, and the rotating ring 301 is fixed to the bottom of the rotating disc 15. A plurality of array - arranged jacks 302 are formed in the side wall of the rotating ring 301, and a latch 303 is connected to the side wall of the support rod 14 through a first reset mechanism 4. The first reset mechanism 4 enables the latch 303 to withdraw from the jack 302. Then, the rotating disc 15 is rotated to adjust the installation direction of the tri - axis acceleration sensor body 16. After the adjustment is completed, the first moving block 402 is released. At this time, the latch 303 can be inserted into the jack 302 again under the action of the first reset mechanism 4 for limiting, so as to facilitate the rotational adjustment of the tri - axis acceleration sensor body 16.

[0030] The first reset mechanism 4 includes two symmetrically arranged first T - shaped guide rods 401 fixedly connected to the side wall of the support rod 14. A first moving block 402 is sleeved on the side wall of the first T - shaped guide rod 401. A first spring 403 is sleeved on the side wall of the first T - shaped guide rod 401, and the latch 303 is fixed to the side wall of the first moving block 402, which plays a guiding and resetting role for the movement of the latch 303.

[0031] The first pushing mechanism 5 includes a push rod 501 fixedly connected to the end of the piston 25, and the other end of the push rod 501 is fixedly connected to a second moving block 502. The second moving block 502 is connected to the side wall of the first connecting pipe 21 through a second reset mechanism 6. A push block 503 is fixedly connected to the side wall of the second moving block 502. A first support plate 504 is fixedly connected to the bottom of the rotating disc 15. A circular ring 506 is rotatably connected to the side wall of the first support plate 504 through a first rotating shaft 505. A plurality of array - arranged protrusions 507 are fixedly connected to the side wall of the circular ring 506, and the rotation of the first rotating shaft 505 is driven by a driving mechanism 7. By driving the first rotating shaft 505 to rotate through the driving mechanism 7, the circular ring 506 is driven to rotate. When the push block 503 abuts against the side wall of the protrusion 507, the piston 25 is pushed to move through the second moving block 502 and the push rod 501. When the push block 503 passes over the protrusion 507, the piston 25 can move and reset under the action of the second reset mechanism 6, so that the piston 25 reciprocates in the fixed pipe 24.

[0032] The second reset mechanism 6 includes two symmetrically arranged second T - shaped guide rods 601 fixedly connected to the side wall of the first connecting pipe 21. The second moving block 502 is sleeved on the side wall of the second T - shaped guide rod 601. A fixed ring 602 is fixedly sleeved on the side wall of the second T - shaped guide rod 601, and a second spring 603 is sleeved on the side wall of the second T - shaped guide rod 601, which plays a guiding and resetting role for the movement of the second moving block 502 and the piston 25.

[0033] The driving mechanism 7 includes a driven bevel gear 701 fixedly connected to one end of the first rotating shaft 505. And a second support plate 702 is fixedly connected to the bottom of the rotating disk 15. A driving bevel gear 704 is rotatably connected to the side wall of the second support plate 702 through a second rotating shaft 703. And a gear 705 is fixedly sleeved on the side wall of the second rotating shaft 703. Two symmetrically arranged fixing rods 706 are fixedly connected to the bottom of the rotating disk 15. And a stop block 707 is fixedly connected to the lower end of the fixing rod 706. A third spring 708 is sleeved on the side wall of the fixing rod 706. And a rack 709 is sleeved on the side wall of the fixing rod 706. A moving rod 710 is inserted into the top of the rotating disk 15. And the lower end of the moving rod 710 is fixed to the top of the rack 709. After the triaxial acceleration sensor body 16 is adjusted, the protective cover 18 is screwed onto the side wall of the threaded tube 17, which can protect the triaxial acceleration sensor body 16 and the spirit level 202. At the same time, when the protective cover 18 moves downward, it abuts against the upper end of the moving rod 710, thereby pushing the rack 709 downward. At the same time, the third spring 708 is compressed and drives the driving bevel gear 704 to rotate. The rotation of the driving bevel gear 704 drives the rotation of the driven bevel gear 701 and the first rotating shaft 505.

[0034] The opening and closing mechanism 8 includes a fixed cover 801 fixedly inserted into the side wall of the air inlet pipe 26. And a sliding plate 802 is connected in the fixed cover 801 through a third reset mechanism 9. A circular hole 803 is formed in the top of the sliding plate 802. And the movement of the sliding plate 802 is pushed by a second pushing mechanism 10. When the protective cover 18 needs to be disassembled, the sliding plate 802 is pushed into the fixed cover 801 by the second pushing mechanism 10, so that the circular hole 803 is aligned with the air inlet pipe 26, enabling external air to enter the protective cover 18 through the air inlet pipe 26, so that the inside of the protective cover 18 is no longer in a negative pressure state, thus facilitating the disassembly of the protective cover 18.

[0035] The third reset mechanism 9 includes two symmetrically arranged first connection blocks 901 fixedly connected to the side wall of the sliding plate 802. And a third T-shaped guide rod 902 is fixedly connected to the side wall of the first connection block 901. A fourth spring 904 is sleeved on the side wall of the third T-shaped guide rod 902. A second connection block 903 is sleeved on the side wall of the third T-shaped guide rod 902. And the second connection block 903 is fixed to the side wall of the fixed cover 801, which plays a role in guiding and resetting the movement of the sliding plate 802.

[0036] The second driving mechanism 10 includes two symmetrically arranged fixing blocks 1001 fixedly connected to the side wall of the sliding plate 802. The side wall of the fixing block 1001 is rotatably connected to a pushing plate 1003 through a rotating pin 1002. The pushing plate 1003 includes an inclined surface 1004, and a baffle 1005 is fixedly connected to the side wall of the sliding plate 802. When installing the protective cover 18, when the gear 705 rotates counterclockwise, at this time, the single tooth of the gear 705 abuts against the bottom of the pushing plate 1003, thereby pushing the pushing plate 1003 to rotate upward along the rotating pin 1002. At this time, the sliding plate 802 will not be pushed to move, and the sliding plate 802 keeps the air inlet pipe 26 in a sealed state. When the protective cover 18 needs to be disassembled, the protective cover 18 moves upward. At this time, the rack 709 can move upward and reset under the action of the third spring 708, thereby pushing the gear 705 to rotate clockwise. At this time, the single tooth of the gear 705 abuts against the inclined surface 1004, and under the action of the baffle 1005, the pushing plate 1003 cannot rotate downward, thereby pushing the sliding plate 802 to slide into the fixed cover 801.

[0037] Working principle: When in use, when the triaxial acceleration sensor body 16 needs to be installed, the bearing seat 1 is fixed by the fixing bolts. Then, the universal ball 13 is rotated, and the spirit level 202 is observed, so as to level the rotating disk 15 and the triaxial acceleration sensor body 16. After leveling, the bolt 204 is screwed into the threaded hole 203 and tightened, so as to tightly fix the universal ball 13. Then, the first moving block 402 is pulled, so that the plug pin 303 withdraws from the jack 302, and at the same time, the first spring 403 is compressed. Then, the rotating disk 15 is rotated to adjust the installation direction of the triaxial acceleration sensor body 16. After the adjustment is completed, the first moving block 402 is released. At this time, the plug pin 303 can be inserted into the jack 302 again under the action of the first spring 403 for limiting. Therefore, when installing the triaxial acceleration sensor body 16, it is convenient to level and adjust the angle of it, that is, it is convenient to adjust the orientations of the X-axis, Y-axis and Z-axis of the triaxial acceleration sensor body 16, ensuring the detection effect and making the adjustment more convenient and fast.

[0038] After the adjustment of the triaxial acceleration sensor body 16 is completed, the protective cover 18 is screwed onto the side wall of the threaded tube 17, which can protect the triaxial acceleration sensor body 16 and the spirit level 202. At the same time, when the protective cover 18 moves downward, it abuts against the upper end of the moving rod 710, thereby pushing the rack 709 downward. At the same time, the third spring 708 is compressed, and the driving bevel gear 704 is driven to rotate. The rotation of the driving bevel gear 704 drives the rotation of the driven bevel gear 701 and the first rotating shaft 505, and further drives the rotation of the ring 506. When the pushing block 503 abuts against the side wall of the protrusion 507, the piston 25 is pushed to move through the second moving block 502 and the pushing rod 501. At the same time, the second spring 603 is compressed. When the pushing block 503 passes over the protrusion 507, the piston 25 can move back under the action of the second spring 603, so that the piston 25 reciprocates in the fixed tube 24. When the piston 25 moves away from the first connecting tube 21, a negative pressure is generated in the first connecting tube 21. At the same time, the first one-way valve 20 opens and the second one-way valve 23 closes. At this time, the air in the protective cover 18 is pumped into the first connecting tube 21 through the exhaust pipe 19. When the piston 25 moves toward the first connecting tube 21, the air in the first connecting tube 21 is squeezed. At the same time, the first one-way valve 20 closes and the second one-way valve 23 opens. At this time, the air in the first connecting tube 21 is discharged through the second connecting tube 22. In this way, the air in the protective cover 18 can be automatically discharged and a negative pressure is formed, which can not only prevent the humid air from affecting the triaxial acceleration sensor body 16, but also hinder the conduction of heat, thereby avoiding the influence of high temperature and low temperature on the triaxial acceleration sensor body 16 and ensuring its service effect and life;

[0039] At the same time, when installing the protective cover 18, when the gear 705 rotates counterclockwise, at this time, the single tooth of the gear 705 abuts against the bottom of the push plate 1003, thereby pushing the push plate 1003 to rotate upward along the rotating pin 1002. At this time, the sliding plate 802 will not be pushed to move, and the sliding plate 802 keeps the air inlet pipe 26 in a sealed state. When it is necessary to disassemble the protective cover 18, the protective cover 18 moves upward. At this time, the rack 709 can move back upward under the action of the third spring 708, thereby pushing the gear 705 to rotate clockwise. At this time, the single tooth of the gear 705 abuts against the inclined surface 1004, and under the action of the baffle 1005, the push plate 1003 cannot rotate downward, thereby pushing the sliding plate 802 to slide into the fixed cover 801, making the round hole 803 align with the air inlet pipe 26. At the same time, the fourth spring 904 is compressed, so that the external air can enter the protective cover 18 through the air inlet pipe 26, making the inside of the protective cover 18 no longer in a negative pressure state, thus facilitating the disassembly of the protective cover 18.
