[0013] 1. The strip float valve with diversion distribution is provided with a valve foot, a hook foot, a torsion spring, a card plate, a card slot, a sliding rod, a second spring and a connecting rod. Before inserting the valve foot into the hole, the hook foot is first rotated to make the connecting sleeve twist the torsion spring. With the continuous rotation of the hook foot, the card plate will be inserted into the inside of the valve foot from the opening groove. At this time, the connecting rod is pressed down to make the sliding rod slide in the valve foot and the second spring is stretched at the same time, so that the card plate is buckled in the card slot. The rebound of the second spring makes the sliding rod fix the hook foot by the card slot, so as to facilitate the staff to insert and install. After inserting into the hole, the connecting rod is pressed down again to make the card plate disengage from the card slot. The hook foot and the valve foot are kept vertical by the rotation of the torsion spring, so as to play a hooking role.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a strip float valve with a guide distribution, including a valve plate 1, strip valve legs 2 are connected to the four corners above the valve plate 1, a guide plate 3 is connected to the bottom of the valve plate 1, a connecting groove 4 is opened above the valve plate 1, friction pads 22 are connected to the groove walls on both sides of the connecting groove 4, the bottom of the guide plate 3 is a sloped design and a guide groove 23 is provided, when the connecting strip 7 slides into the connecting groove 4, the friction pad 22 will be squeezed and deformed, thereby fitting and contacting with the connecting strip 7 to increase friction, avoid accidental sliding of the connecting strip 7, and improve the stability of the fixation.

[0022] The first spring 5 is connected to the inside of the connecting groove 4 on both sides, and a fixed block 6 is connected to one end of the first spring 5. A connecting strip 7 is slidably connected in the connecting groove 4, and fixing grooves 24 are provided on both sides of the connecting strip 7. The side of the fixing block 6 away from the first spring 5 is hemispherical in design. The fixing block 6 slides inside the valve plate 1 and is engaged with the fixing groove 24. Through the hemispherical surface on one side of the fixing block 6, the connecting strip 7 can flexibly and quickly push the fixing block 6 to move, thereby facilitating the staff to install and disassemble the connecting strip 7.

[0023] A valve foot 8 is connected to the bottom of the connecting strip 7, and a fixing rod 9 is connected to the bottom of the valve foot 8. The valve foot 8 is rotatably connected to the hook foot 10 through the fixing rod 9. A guide hole 20 is provided on the valve foot 8 on one side below the valve plate 1. The valve foot 8 and the hook foot 10 are perpendicular to each other. A stop plate 21 is connected to the bottom of the valve foot 8, and the stop plate 21 contacts the hook foot 10. When the hook foot 10 and the valve foot 8 are perpendicular to each other, the stop plate 21 will stop the hook foot 10, thereby preventing the hook foot 10 from rotating downward, thereby ensuring the vertical state of the hook foot 10 and the valve foot 8.

[0024] An open groove 11 is provided on the valve foot 8, and a sliding rod 12 is slidably connected inside the valve foot 8. A card slot 13 is provided on the sliding rod 12, and a connecting rod 15 is connected to one end of the sliding rod 12. A pull rod 16 is rotatably connected to the connecting rod 15. A cylindrical slide groove is provided inside the connecting strip 7, and a baffle 14 is connected to the position where the cylindrical slide groove is provided on the connecting strip 7. The connecting rod 15 is slidably connected to the baffle 14, and a second spring 25 is connected below the baffle 14. One end of the second spring 25 is connected to the sliding rod 12. When the connecting rod 15 is pressed down, the connecting rod 15 will slide in the cylindrical slide groove, and the sliding rod 12 will slide in the valve foot 8. While sliding, the second spring 25 will be stretched, so that the card slot 13 is prompted to fix the card plate 18 through the rebound force of the second spring 25, so that the hook foot 10 fits with the valve foot 8, which is convenient for the staff to install.

[0025] A connecting sleeve 17 is connected to the hook foot 10, and a clamping plate 18 is connected to the hook foot 10. The connecting sleeve 17 is rotatably connected to the fixed rod 9. Torsion springs 19 are sleeved on both ends of the fixed rod 9. One end of the torsion spring 19 is connected to the valve foot 8, and the other end of the torsion spring 19 is connected to the connecting sleeve 17. The clamping plate 18 is L-shaped and is interlocked with the clamping groove 13. When the hook foot 10 is rotated to make the hook foot 10 fit and contact with the valve foot 8, the torsion spring 19 will be twisted, so that after the clamping plate 18 is separated from the clamping groove 13, the hook foot 10 is driven to rotate by the rotation of the torsion spring 19, so that the hook foot 10 and the valve foot 8 remain in a vertical state.

[0026] The working principle of the utility model is:

[0027] The staff first rotates the hook foot 10 to make the connecting sleeve 17 twist the torsion spring 19, and prompts the clamping plate 18 to be inserted into the valve foot 8 from the opening groove 11. At this time, the connecting rod 15 is pressed down to make the sliding rod 12 slide in the valve foot 8 and at the same time stretch the second spring 25, so that the clamping plate 18 can be buckled in the clamping groove 13, and the connecting rod 15 is released to use the rebound of the second spring 25 to make the sliding rod 12 fix the hook foot 10 through the clamping groove 13, and then push the connecting strip 7 into the connecting groove 4. At this time, the fixing block 6 will be squeezed into the valve plate 1 by the connecting strip 7 to compress the first spring 5, so that the rebound of the first spring 5 is used to make the fixing block 6 and the fixing groove 24 fit together, and the connecting strip 7 together with the valve foot 8 is fixed on the valve plate 1, and then the valve foot 8 is inserted into the hole on the tower plate, and the connecting rod 15 is pressed down again to make the clamping plate 18 disengage from the clamping groove 13, and the hook foot 10 is driven to rotate by the rotation of the torsion spring 19, so that the hook foot 10 and the valve foot 8 remain vertical.
