DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] As From Figure 1 to Figure 2 shown, an embodiment of the present utility model provides an automatic locking device with rollers, including a base 1. An oil cylinder base 9 is installed inside the base 1. An oil cylinder body 5 is installed at the upper end of the oil cylinder base 9. An oil cylinder piston shaft 8 is installed inside the oil cylinder body 5. A T-shaped bolt 2 is installed through the inside of the oil cylinder piston shaft 8. A track 14 is installed at the lower end of the base 1. A T-shaped groove is provided on one side of the track 14 close to the oil cylinder body 5. The lower end of the T-shaped bolt 2 is movably installed inside the T-shaped groove. A roller frame 12 is movably sleeved outside the rod body of the T-shaped bolt 2 between the oil cylinder piston shaft 8 and the track 14. Rollers 13 are respectively movably installed at both ends of the roller frame 12. The rollers 13 are in contact with the track 14.

[0019] As Figure 1 shown in Figure 2 another embodiment of the present utility model, a locking nut 3 is installed on the outside of the rod body at the upper end of the T-shaped bolt 2 through threads. A nut anti-rotation block 4 is installed on the outside of the locking nut 3. The nut anti-rotation block 4 is connected to the oil cylinder body 5. An oil cylinder lifting joint 6 and an oil cylinder locking joint 7 are respectively provided at one end inside the oil cylinder body 5. The oil cylinder lifting joint 6 and the oil cylinder locking joint 7 are respectively externally connected to a hydraulic control oil circuit. A roller shaft 15 is movably installed through the rear end inside the roller frame 12. The rollers 13 are respectively sleeved at both ends of the rod body of the roller shaft 15. A lubricating oil passage is provided between the roller shaft 15 and the roller frame 12 and is communicated with the rollers 13. A lifting ball column 10 is sleeved outside the rod body of the T-shaped bolt 2 between the oil cylinder piston shaft 8 and the roller frame 12. The lower end of the lifting ball column 10 is spherical, and the lower end of the lifting ball column 10 is connected to the roller frame 12. A guide sleeve 11 is sleeved outside the lifting ball column 10. The outside of the guide sleeve 11 is connected to the inside of the oil cylinder base 9.

[0020] When it is necessary to drive the base 1 to move, the oil cylinder lifting joint 6 connects to the control oil circuit. Then, the oil cylinder lifting joint 6 cooperates with the oil cylinder body 5 to push the oil cylinder piston shaft 8 and the T-bolt 2 downward, separating the lower end of the T-bolt 2 from the upper surface of the T-slot. At the same time, the T-bolt 2 also drives the roller frame 12 and the roller 13 downward. Then, after the roller 13 contacts the track 14, the oil cylinder body 5 continues to apply pressure to the track 14 through the oil cylinder piston shaft 8 and the T-bolt 2, causing the oil cylinder body 5 to drive the oil cylinder seat 9 and the base 1 to move upward to complete the lifting. Then, the user can adjust the position of the base 1 along the track 14 with the assistance of an external device in cooperation with the roller 13. After the base 1 moves to the designated position, the oil cylinder locking joint 7 connects to the control oil circuit. Then, the oil cylinder body 5 controls the oil cylinder piston shaft 8 to be stressed upward. Then, the oil cylinder piston shaft 8 can move upward through the lifting locking nut 3 and the T-bolt 2, causing the T-bolt 2 to drive the roller 13 to move. Then, after the T-bolt 2 fits tightly with the upper inner end of the T-slot, automatic locking can be achieved, making the base 1 more stable.

[0021] The working principle of this automatic locking device with rollers:

[0022] During use, first, when it is necessary to drive the base 1 to move, the oil cylinder lifting joint 6 connects to the control oil circuit. Then, the oil cylinder lifting joint 6 cooperates with the oil cylinder body 5 to push the oil cylinder piston shaft 8 and the T-bolt 2 downward, separating the lower end of the T-bolt 2 from the upper surface of the T-slot. At the same time, the T-bolt 2 also drives the roller frame 12 and the roller 13 downward. Then, after the roller 13 contacts the track 14, the oil cylinder body 5 continues to apply pressure to the track 14 through the oil cylinder piston shaft 8 and the T-bolt 2, causing the oil cylinder body 5 to drive the oil cylinder seat 9 and the base 1 to move upward to complete the lifting. Then, the user can adjust the position of the base 1 along the track 14 with the assistance of an external device in cooperation with the roller 13. After the base 1 moves to the designated position, the oil cylinder locking joint 7 connects to the control oil circuit. Then, the oil cylinder body 5 controls the oil cylinder piston shaft 8 to be stressed upward. Then, the oil cylinder piston shaft 8 can move upward through the lifting locking nut 3 and the T-bolt 2, causing the T-bolt 2 to drive the roller 13 to move. Then, after the T-bolt 2 fits tightly with the upper inner end of the T-slot, automatic locking can be achieved, making the base 1 more stable.

[0023] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation modes of the present invention. For those of ordinary skill in the art, based on the above description, other different forms of changes or modifications can be made. It is impossible to enumerate all the implementation modes here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
