DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-3 , an embodiment provided by the present invention:

[0018] The automatic transmission valve plate includes a cylinder 1, in which a fixed disk 2 is fixedly installed, a one-way valve 3 is fixedly embedded on the right side of the upper end of the fixed disk 2, and a guide cylinder 4 is connected to the left end of the one-way valve 3. The end of the guide cylinder 4 away from the one-way valve 3 is fixedly penetrated through one of the fixed disks 2, and a sealing column 5 for blocking or opening the flow of the guide cylinder 4 is movably embedded on the two guide cylinders 4.

[0019] When in use, when one sealing column 5 blocks the guide tube 4, the other sealing column 5 opens the guide tube 4, and conduction is achieved by indirect replacement of one guide tube 4 being blocked and the other guide tube 4 being sealed. Combined with the function of the one-way valve 3, the flow direction in the cylinder 1 can be left or right, thereby improving the usability of the device.

[0020] In this embodiment, a connecting rod 6 is welded to one end of the sealing column 5 away from the guide tube 4 , and a rack 7 is fixedly mounted to one end of the connecting rod 6 away from the sealing column 5 , and a sliding groove 8 is provided on the rack 7 .

[0021] In this embodiment, a fixing plate 9 is fixedly installed between the two fixing plates 2 , and a rack 7 is slidably penetrated in the fixing plate 9 .

[0022] In this embodiment, a rotating shaft 10 that can rotate relative to the fixed plate 9 is provided at the center of the fixed plate 9, and a second gear 12 is provided on the outer surface fixed sleeve at the center of the rotating shaft 10. The second gear 12 runs through the fixed plate 9, and a first gear 11 is provided on the outer surface fixed sleeve at the front end of the rotating shaft 10.

[0023] In this embodiment, a cylinder 14 is fixedly installed at the front end of the fixed plate 9 located on the right side of the rotating shaft 10, and a movable plate 15 is fixedly installed at the telescopic end of the cylinder 14. The movable plate 15 is fixedly installed with a first rack 16 by bolts, and the first rack 16 is meshed and connected with the first gear 11; the movable plate 15 can be driven to move by the extension and contraction of the cylinder 14, and the movement of the movable plate 15 pushes the first rack 16 to move, and the first rack 16 acts on the first gear 11 during the movement, so that the first gear 11 rotates, driving the rotating shaft 10 to rotate, and the rotation of the rotating shaft 10 drives the second gear 12 to rotate at the same time, and the second gear 12 acts on the rack 7 during the rotation of the second gear 12, The rack 7 pushes the movement of the connecting rod 6, and when the connecting rod 6 moves, it drives one sealing column 5 to block the guide tube 4, and the other sealing column 5 opens the guide tube 4.

[0024] In this embodiment, a movable groove 13 is formed on the fixed plate 9 at the front end of the rotating shaft 10 and the cylinder 14 , and a movable plate 15 slides on the movable groove 13 .

[0025] Working principle: When in use, the movable plate 15 can be moved by the extension and retraction of the cylinder 14, and the movement of the movable plate 15 pushes the first rack 16 to move. During the movement of the first rack 16, it acts on the first gear 11, causing the first gear 11 to rotate, driving the rotating shaft 10 to rotate, and the rotation of the rotating shaft 10 drives the second gear 12 to rotate. During the rotation of the second gear 12, it acts on the rack 7, and the rack 7 pushes the movement of the connecting rod 6. During the movement of the connecting rod 6, when a sealing column 5 blocks the guide tube 4, the other sealing column 5 opens the guide tube 4. Through the indirect replacement of one guide tube 4 being blocked and the other guide tube 4 being sealed, conduction is achieved. Combined with the action of the one-way valve 3, the flow direction in the cylinder 1 can be left or right, thereby improving the usability of the device.

[0026] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
