[0024] The following is combined with Figure 1-5 While describing the preferred embodiments of the present invention, it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] Reference Figure 1 、 Figure 2 and Figure 3The utility model multifunctional pneumatic electronic column micrometer includes an electronic column micrometer body 1, the bottom of the electronic column micrometer body 1 is fixedly connected to a base box 2, a bidirectional threaded rod 3 is rotatably connected between the two sides of the inner wall of the base box 2, and the center of the outer wall of the bidirectional threaded rod 3 is fixedly connected to the second gear 19. The inner wall of the base box 2 is located below the second gear 19 and is rotatably connected to a lower rotating rod 20, and one end of the lower rotating rod 20 located outside the base box 2 is fixedly connected to a handle 21, and the center of the outer wall of the lower rotating rod 20 is fixedly connected to a second worm 22 meshing with the second gear 19. When in use, the staff can rotate the lower rotating rod 20 through the handle 21 to drive the second worm 22 to rotate. When the second worm 22 rotates, it will drive the second gear 19 and the bidirectional threaded rod 3 to rotate.

[0026] Reference Figure 1 、 Figure 3 and Figure 4 , the upper surface of the base box 2 is located on both sides of the electronic column micrometer body 1 and is provided with openings 4. A slide rail 5 is provided inside the opening 4 along the length direction of the opening 4. The outer portion of the slide rail 5 is sleeved with a sliding sleeve 6 adapted to the slide rail 5. The lower portion of the sliding sleeve 6 is fixedly connected with a threaded sleeve 7 engaged with the bidirectional threaded rod 3. When the second gear 19 drives the bidirectional threaded rod 3 to rotate, the two threaded sleeves 7 move in opposite directions along the bidirectional threaded rod 3 at the same time, thereby driving the two sliding sleeves 6 to move in opposite directions to each other;

[0027] Reference Figure 2 A communication port 8 is provided on one side of the outer wall of the electronic column micrometer body 1, and a sealing cover 9 is fixedly connected above the sliding sleeve 6 for sealing the communication port 8 of the electronic column micrometer body 1. By controlling the rotation of the bidirectional threaded rod 3, the threaded sleeve 7, the sliding sleeve 6 and the sealing cover 9 can be driven to move toward the electronic column micrometer body 1 at the same time until the two sealing covers 9 abut against each other, thereby sealing the communication port 8 of the electronic column micrometer body 1;

[0028] Reference Figure 3 、 Figure 4 and Figure 5 , both sides of the outer wall of the bidirectional threaded rod 3 are fixedly connected with a first worm 14, and the outer walls of the threaded barrel 11 are fixedly connected with a first gear 15 meshing with the first worm 14. A lifting plate 10 is provided at the bottom of the base box 2. Four rectangularly distributed threaded barrels 11 are rotatably connected to the inner top wall of the base box 2. The four threaded barrels 11 are rotatably connected to the inner top wall of the base box 2 through bearings. The threaded barrel 11 is threadedly connected to a threaded rod 12 that matches the threaded barrel 11. A lower through hole 13 that matches the threaded rod 12 is opened at the bottom of the base box 2. The end of the threaded rod 12 away from the threaded barrel 11 passes through the lower through hole 13 and is fixedly connected to the lifting plate 10;

[0029] Reference Figure 3 、 Figure 4 and Figure 5 When the bidirectional threaded rod 3 rotates and drives the sealing cover 9 to move away from the electronic column micrometer body 1, the first worm 14 rotates along with the bidirectional threaded rod 3 and drives the first gear 15 fixedly connected to the outer wall of the threaded barrel 11 to rotate, thereby driving the threaded barrel 11 to rotate. The rotation of the threaded barrel 11 drives the threaded rod 12 to move upward until the lifting plate 10 abuts the base box 2;

[0030] Reference Figure 3 、 Figure 4 and Figure 5 , side through-holes 16 are provided on both sides of the outer wall of the base box 2, and a connecting rod 17 adapted to the side through-holes 16 is fixedly connected to the side of the outer wall of the threaded sleeve 7 away from the electronic column micrometer body 1, and a lateral support block 18 is fixedly connected to one end of the outer wall of the connecting rod 17 away from the threaded sleeve 7. When the lifting plate 10 abuts against the base box 2, the lower surface height of the lateral support block 18 is flush with the lower surface height of the lifting plate 10. When the bidirectional threaded rod 3 rotates and drives the sealing cover 9 to move away from the electronic column micrometer body 1, the threaded sleeve 7 drives the lateral support block 18 to move away from the base box 2 through the connecting rod 17, and when the lifting plate 10 abuts against the base box 2, the lower surface of the lateral support block 18 abuts against the desktop;

[0031] Reference Figure 2 and Figure 4 , one side of the top wall of one sealing cover 9 close to the communicating port 8 is provided with an inclined air nozzle 23 with the air outlet facing the communicating port 8, and the inner bottom wall of the sealing cover 9 is fixedly connected with an air cylinder 24, and the inner side wall of the other sealing cover 9 is fixedly connected with a piston plate 25 adapted to the air cylinder 24. The outer side wall of the air cylinder 24 away from the piston plate 25 is provided with a one-way air inlet valve 26 and a one-way air outlet valve 27. The inclined air nozzle 23 and the one-way air outlet valve 27 are connected. When the two sealing covers 9 move toward the side close to the electronic column micrometer body 1, after moving a certain distance, the piston plate 25 enters the air cylinder 24 and The air between the piston plate 25 and the one-way air outlet valve 27 in the squeezed air cylinder 24 is ejected toward the side of the connecting port 8 through the inclined air nozzle 23 due to the action of air pressure, and the dust attached to the surface of the connecting port 8 during use is blown off. When the two sealing covers 9 move toward the side away from the electronic column micrometer body 1, external air can enter the space between the piston plate 25 and the one-way air outlet valve 27 in the air cylinder 24 through the one-way air inlet valve 26, thereby avoiding as much as possible the negative pressure generated in the space between the piston plate 25 and the one-way air outlet valve 27 in the air cylinder 24, which makes it difficult for the sealing cover 9 to move.

[0032] The implementation principle of the present utility model is as follows: when the device needs to be used, the staff can first rotate the lower rotating rod 20 clockwise through the handle 21 to drive the second worm 22 to rotate. When the second worm 22 rotates, it will drive the second gear 19 and the bidirectional threaded rod 3 to rotate, so that the two threaded sleeves 7 move away from the second gear 19, so that the two sliding sleeves 6 and the two sealing covers 9 move away from the electronic column micrometer body 1. At the same time, the first worm 14 rotates with the bidirectional threaded rod 3 and drives the first gear 15 fixedly connected to the outer wall of the threaded barrel 11 to rotate, thereby driving the threaded barrel 11 to rotate, and the rotation of the threaded barrel 11 drives the threaded rod 12 to move upward until the lifting plate 10 abuts against the base box 2;

[0033] While the bidirectional threaded rod 3 rotates and drives the two sealing covers 9 to move away from the electronic column micrometer body 1, the threaded sleeve 7 drives the lateral support block 18 to move away from the base box 2 through the connecting rod 17, and when the lifting plate 10 abuts the base box 2, the lower surface of the lateral support block 18 abuts the desktop, so that the lateral support block 18 and the lifting plate 10 simultaneously support the base box 2 and the electronic column micrometer body 1 fixedly connected to the base box 2, thereby enhancing the support surface of the base box 2 and improving the stability of the device when in use;

[0034] When the device is used, the lower rotating rod 20 is rotated counterclockwise by the handle 21 to drive the second worm 22 to rotate. When the second worm 22 rotates, it will drive the second gear 19 and the bidirectional threaded rod 3 to rotate, so that the two threaded sleeves 7 move toward the side close to the second gear 19, and the two sliding sleeves 6 and the two sealing covers 9 move toward the side of the electronic column micrometer body 1 until the two sealing covers 9 abut against each other, thereby sealing the communication port 8 provided on the outer wall of the electronic column micrometer body 1, so as to avoid as much as possible that dust falls into the communication port 8 when the electronic column micrometer body 1 is not used for measurement, resulting in deviation in the measurement result when the electronic column micrometer body 1 is used for measurement;

[0035] When the two sealing covers 9 approach each other, the piston plate 25 enters the air cylinder 24 and squeezes the air between the piston plate 25 and the one-way air outlet valve 27 in the air cylinder 24. Due to the action of air pressure, the squeezed air is ejected toward the side of the connecting port 8 through the inclined air nozzle 23, and blows off the dust attached to the surface of the connecting port 8 during use.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
