Detailed implementation manners

[0027] The following details the embodiments of the present invention. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] Please refer to Figures 1 to 10, the present invention provides a calibration and adjustment platform for a bubble level 4, including an upper support plate 1, a lower support assembly, and a base 2. The upper end surface of the upper support plate 1 has a plurality of first scale lines 3. A bubble level 4 is placed on the upper support plate 1. The upper end surface of the base 2 has a plurality of second scale lines 7. A plain bearing 8 is provided in the middle of the base 2. The plain bearing 8 includes a lower cover end 25, a rolling element 26 end, and an upper cover end 27. The rolling element 26 is disposed between the lower cover end 25 and the upper cover end 27, and the lower cover end 25 is embedded in the upper end surface of the base 2, and the upper cover end 27 is embedded in the lower end surface of the upper support plate 1. The adjusting nut 5 is threadedly connected to the first screw 6 and sleeved under the first screw 6. The connecting member is disposed under the base 2.

[0029] In this embodiment, the overall shape of the base 2 of this design can be circular or square; both the first scale line 3 and the second scale line 7 are circumferential octant lines; the rolling element 26 of the plain bearing 8 plays a supporting and rolling role, making the upper support plate 1 always parallel to the base 2 and capable of rotating at any angle, and during the rotation, keeping the positional accuracy between the upper support plate 1 and the base 2 unchanged. And the larger the plain bearing 8, the more stable it is. The upper support plate 1 and the base 2 are symmetrically arranged about the center line to facilitate observing whether the placement position of the bubble level 4 body is in the middle. And the setting of the adjusting nut 5 and the first screw 6 can facilitate the adjustment of the height of the base 2, thereby improving the calibration efficiency.

[0030] Further, the diameter of the upper support plate 1 is smaller than the diameter of the base 2, and the first scale line 3 and the second scale line 7 can be arranged in an aligned state.

[0031] In this embodiment, this design facilitates observing the rotation angle between the upper support plate 1 and the base 2.

[0032] Further, the upper end surface of the upper support also has two scale lines 9. The two scale lines 9 are symmetrically arranged on the corresponding two first scale lines 3 respectively, and the bubble level 4 is located on the two scale lines 9.

[0033] In this embodiment, by symmetrically arranging the two scale lines 9 on both sides of the bubble level 4 body, it provides additional reference points for the calibration of the bubble level 4 body, which helps to further improve the accuracy and efficiency of calibration.

[0034] Further, the bubble level 4 calibration and adjustment platform further includes a plurality of auxiliary components. The auxiliary components include a driven gear 10 and a mounting cover 11. An active gear 12 is arranged inside the mounting cover 11, and the active gear 12 is rotated by a knob 13. The volume of the active gear 12 is smaller than that of the driven gear 10. The driven gear 10 is arranged outside the connecting member. The mounting cover 11 is fixedly connected to the base 2 and covers the lower end surface of the base 2. Both the connecting member and the driven gear 10 are located inside the mounting cover 11. The active gear 12 meshes with the driven gear 10 and is located outside the driven gear 10.

[0035] In this embodiment, the small-volume active gear 12 is rotated by the knob 13, and the active gear 12 drives the large-volume driven gear 10, thereby adjusting the height of the lower support assembly and realizing the fine-tuning function of the platform.

[0036] Further, the connecting member includes a collar 14 and a polygonal rod 15. One end of the polygonal rod 15 is provided with a second screw 16. A fixing nut 17 is arranged on the second screw 16. The other end of the polygonal rod 15 is provided with a connecting ring 18. The outer side of the connecting ring 18 has an annular groove 19. The base 2 has a plurality of polygonal grooves 20. The collar 14 is rotatably connected to the connecting ring 18 and sleeved outside the connecting ring 18 and also embedded in the annular groove 19. The first screw 6 is fixedly connected to the collar 14 and is located below the collar 14. The driven gear 10 is fixedly connected to the collar 14 and sleeved outside the collar 14. The polygonal rod 15 is slidably connected to the base 2 and is located in the corresponding polygonal groove 20, and the fixing nut 17 abuts against the upper end surface of the base 2.

[0037] In this embodiment, by rotatably connecting the collar 14 and the connecting ring 18, the first screw 6 can rotate on its own. The arrangement of the second screw 16 and the fixing nut 17 facilitates fixing the polygonal rod 15 below the base 2.

[0038] Further, a conical seat 21 is arranged below the adjusting nut 5, and steel balls 22 are arranged below the conical seat 21.

[0039] In this embodiment, the arrangement of the steel balls 22 helps to provide stable support during adjustment and reduce the friction between the adjusting nut 5 and the ground. In addition, the steel balls 22 can also reduce vibration and noise to a certain extent.

[0040] Furthermore, a plurality of limiting rods 23 are provided below the mounting cover 11, a plurality of limiting sleeves 24 are provided on the outer side of the adjusting nut 5, and the limiting rods 23 are slidably connected to the limiting sleeves 24 and are located within the limiting sleeves 24.

[0041] In this embodiment, through such a design, the movement range of the adjusting nut 5 is restricted, preventing it from rotating automatically along with the first screw rod 6, and at the same time, the stability of the platform is also increased.

[0042] Furthermore, a first semi-circular ring 29 and a second semi-circular ring 30 are provided at the outer edge of the base 2. Both the first semi-circular ring 29 and the second semi-circular ring 30 are provided with a first insertion hole 32 and a second insertion hole 33. A fixing sleeve 34 is provided at the outer edge of the upper support plate 1. A plug rod 35 is slidably arranged within the fixing sleeve 34. One end of the plug rod 35 is provided with a pull ring 36. A spring 31 is provided between the pull ring 36 and the fixing sleeve 34. The other end of the plug rod 35 is inserted into the first insertion hole 32 of the first semi-circular ring 29.

[0043] In this embodiment, if it is impossible to judge whether the zero position of the bubble level 4 is accurate, the method is as follows: when the bubble level 4 is placed directly above the upper support plate 1, even if the bubble is not at the zero position, remember the current position. Without adjusting the height, just rotate the upper support plate 1 together with the bubble level 4 by 180 degrees. When the position of the bubble remains unchanged, it indicates that the zero position of the bubble level 4 is accurate; otherwise, it is inaccurate. When pulling the plug rod 35 to move it out of the first insertion hole 32 of the first semi-circular ring 29, rotate the upper support plate 1 together with the bubble level 4 counterclockwise or clockwise, so that the plug rod 35 automatically inserts into the second insertion hole 33 of the first semi-circular ring 29 under the action of the spring 31 or the plug rod 35 automatically inserts into the second insertion hole 33 of the second semi-circular ring 30 under the action of the spring 31, which indicates that the upper support plate 1 rotates the bubble level 4 by 90°. And when the plug rod 35 is inserted into the first insertion hole 32 of the second semi-circular ring 30, it indicates that the upper support plate 1 rotates the bubble level 4 by 180°.

[0044] Furthermore, two electric telescopic rods 37 are symmetrically arranged on the upper end surface of the upper support plate 1. The output end of the electric telescopic rod 37 is provided with a pushing block 38, and the bubble level 4 is located between the pushing blocks 38 of the two electric telescopic rods 37.

[0045] In this embodiment, when the bubble level 4 is placed on the upper end surface of the upper support plate 1 and it is ensured that the bubble level 4 is located between the two scale lines 9, this process can be finely adjusted through the scale lines 9. Subsequently, the two electric telescopic rods 37 are activated to extend simultaneously, and the bubble level 4 then slowly moves towards the center of the upper support plate 1 between the two pushing blocks 38. When the adjustment is completed, the bubble level 4 can coincide with the center of the upper support plate 1 and the rotation center of the plain bearing 8. This design can be applicable to the centering positioning of bubble levels 4 of different sizes or models.

[0046] In the present invention, the bubble level 4 body is stably placed on the upper support plate 1. Through the scale lines 9, more precise adjustment is carried out using them to keep the bubble in the bubble level 4 body centered on both of the two scale lines 9, ensuring that its bubble tube is in a horizontal position. Referring to the first scale line 3 on the upper support plate 1 and the second scale line 7 on the base 2, by rotating the upper support plate 1 within the allowable range of the plain bearing 8 to align them as much as possible, this helps to preliminarily judge the horizontal state of the platform. Carefully observe the position of the bubble in the bubble level 4 body to determine whether it deviates from the center. If the bubble deviates from the center, it is necessary to observe in which direction it deviates, and then adjust the adjusting nut 5 in the deviating direction. The adjustment process is that by rotating the knob 13 clockwise, the driving gear 12 is driven to rotate, thereby driving the driven gear 10 and the connecting member to rotate. The first screw rod 6 is threadedly connected to the adjusting nut 5 under the action of the connecting member, and the adjusting nut 5 moves away from the base 2 under the action of the limit sleeve 24 and the limit rod 23, and the first screw rod 6 realizes fine adjustment. At this time, the change in the position of the bubble in the bubble level 4 should be closely observed. When the bubble level 4 body reaches a completely horizontal state, the rotation of the knob 13 is stopped. Subsequently, the upper support plate 1 is controlled to reverse the bubble level 4 by 180° and place it at the same position, and then the scale reading is taken. If the readings are the same, it means that the relationship between the bubble level 4 and the bubble tube is correct. Otherwise, the knob 13 in the deviating direction needs to be finely adjusted until the readings are exactly the same.

[0047] The above-disclosed is only a preferred embodiment of the present invention. Of course, the scope of the rights of the present invention cannot be limited by this. Those of ordinary skill in the art can understand the entire or partial processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the invention.
