Embodiment 1

[0075] A double-row flapper cover drainage mechanism includes a drain valve 100, a wrench assembly 200, and a flapper cover 300. The drain valve 100 includes a valve cylinder and a counterweight cylinder 102. The counterweight cylinder 102 is sleeved in the valve cylinder, and the counterweight cylinder 102 is driven by falling. The flap cover 300 is closed; when the water is drained, the flap cover 300 is opened, and by controlling the time when the counterweight cylinder 102 begins to fall, the drainage mechanism can be partially drained and fully drained.

[0076] The connecting rod 1023 at the bottom of the counterweight cylinder 102 extends to the outside of the bottom cover 1011 of the valve cylinder, and is connected with a cover block 1024, and the cover block 1024 drives the flapper cover 300 to close. The upper part of the valve cylinder is provided with a ventilation hole 1012. During drainage, the opening and closing of the ventilation hole 1012 controls the valve c...

Embodiment 2

[0081] like figure 1 As shown, a double row flapper cover drainage mechanism includes a drain valve 100, a wrench assembly 200, and flapper cover 300300, such as figure 2 As shown, the drain valve 100 includes a valve cylinder and a counterweight cylinder 102. The counterweight cylinder 102 is sleeved in the valve cylinder. The falling of the counterweight cylinder 102 drives the flapper cover 300 to close; when the water is drained, the flapper cover 300 is opened. The water sealing sheet 301 is a soft rubber material. When the flap 300 is closed, the water sealing sheet 301 and the base 306 are sealed. When the water sealing sheet 301 is separated from the base 306, the drain valve drains the water. By controlling the time when the counterweight cylinder 102 starts to fall, the semi-drainage and the full-drainage of the drainage mechanism are respectively realized.

[0082] like image 3 , Figure 4 As shown, the connecting rod 1023 at the bottom of the counterweight cyl...

Embodiment 3

[0104] like Figure 19 , Figure 20 As shown, the wrench assembly 200 includes a wrench 201, a box body 202, a lifting rod 203, and a connecting assembly. The wrench 201 drives the connecting assembly, and then drives the lifting rod 203. The box body 202 is provided with a gas nozzle 204, an air hole 205, and the wrench 201 The drive connecting assembly drives the lift rod 203. In the full gear position, the gas nozzle 204 is closed, and the pressure chamber is isolated from the atmosphere; in the half gear position, the gas nozzle 204 is opened, and the pressure chamber communicates with the atmosphere. The full gear position and the half gear position in this embodiment are located in the same direction in which the wrench 201 rotates.

[0105] The connecting assembly includes a connecting rod 208, a swing rod 209, and an eccentric wheel 207. The connecting rod 208, the swing rod 209, and the eccentric wheel 207 are rotated and connected in sequence. The lift rod 203 rota...

Abstract

The invention relates to a dual-drainage flapper type drainage mechanism. The dual-drainage flapper type drainage mechanism comprises a drainage valve, a wrench component and a flapper. The drainage valve comprises a valve barrel and a counterweight barrel, wherein the valve barrel sleeves the counterweight barrel, and the counterweight barrel drops to drive the flapper to close. During drainage, the flapper is opened, and semi-drainage and full drainage of the drainage mechanism are achieved by controlling the counterweight barrel dropping start speed. The dual-drainage flapper type drainage mechanism has the advantages that the shortcomings of a pulling dual-drainage flapper type drainage valve in the prior art are overcome, semi-drainage and full drainage are controlled by controlling negative pressure of the counterweight barrel, and the drainage mechanism is simple in integral structure, small in size, high in universal matching performance, good in sealability, convenient to assemble by users, stable in water level after drainage and the like; drainage quantity can be adjusted at a semi-drainage gear, so that water can be saved more effectively; drainage of the drainage mechanism is controlled by the wrench component, and the semi-drainage gear and a full drainage gear can be achieved by one wrench; a lifting rod which can be easily replaced can facilitate maintenance, and accordingly, the drainage mechanism is simple to operate.

Description

technical field [0001] The present invention relates to a toilet drainage assembly, more particularly, to a double row flap cover drainage mechanism. Background technique [0002] Existing pull-type double-row flap-cover type drain valves are mostly double flap-cover type or double-sealing sheet type. For example, Chinese invention patent ZL03273320.8 discloses a double-row drain valve, which mainly includes a base, a flapper cover, an overflow pipe, Double row button mechanism and zipper; the overflow pipe is fixed on the support on one side of the base, the flap cover is covered on the water outlet of the base, one side is pivoted to the support of the base by a pivot rod, and one end of the zipper is connected The other end is connected with the pull rod of the double row button mechanism; the drain valve also includes a half row floating bucket and a full row floating bucket, the half row floating bucket is slidably arranged on the overflow pipe, and the bottom end is pi...
