[0003] In the above-mentioned prior art, the link-type lifting mechanism composed of the pressing rod 41' and the connecting rod 42' ensures that the lifting tube 3' can be pulled smoothly, and the lifting position of the lifting tube 3' reaches the position of the lifting tube. The horizontal distance of 3' needs to have a certain length, and the horizontal distance cannot be shortened arbitrarily, so it is difficult to flexibly select the lifting position of the riser 3' according to the needs, and the lifting position is limited

Embodiment Construction
[0027] Such as Figure 2 to Figure 4 , Figure 2 to Figure 4 A lifting mechanism 4 of a drain valve according to the first embodiment of the present invention is shown. The drain valve includes a valve body 1, an activation element 2, a riser 3 and a lifting mechanism 4. The lifting mechanism 4 is arranged on the valve of the drain valve. In the body 1, it is used to drive and cooperate with the actuating element 2 of the drain valve to pull the lift pipe 3 installed in the valve body 1. The actuating element 2 in this embodiment is a button, and the button is movably installed on the top of the valve body 1 In the provided button seat, the bottom end of the riser 3 is fixedly connected with a valve disc 31 that matches the drain port of the drain valve, and the starting element 2 lifts the riser 3 upwards through the lifting mechanism 4 to drive the valve disc 31 to move upwards. And open the drain port of the drain valve to realize draining. The pulling mechanism 4 at leas...

The invention discloses a lifting mechanism of a drain valve, which is arranged in the valve body of the drain valve, and is used for driving and cooperating with the starting element of the drain valve to lift the lifting pipe installed in the valve body. It is connected with a valve disc matching with the drain port of the drain valve. It is characterized in that the pulling mechanism at least includes a connecting rod I and a connecting rod II. One end of the connecting rod II is pivotally connected to the part between the first end and the second end of the connecting rod II. When the connecting rod II is pulled by the connecting rod I and rotates around the first end of the connecting rod II, the first end of the connecting rod II is opposite to the valve. body forms a yielding displacement, and the second end of the connecting rod II pulls the riser tube. The lifting mechanism can flexibly select the lifting position of the riser tube according to the need under the premise of ensuring smooth lifting of the riser tube, so that it can be selected by selecting The optimal lifting position reduces the torsional moment when lifting the riser, thereby reducing the opening force of the drain valve and achieving labor-saving effects.
Description
technical field [0001] The invention relates to the field of sanitary ware, in particular to a lifting mechanism for a drain valve. Background technique [0002] The lifting mechanism of the existing drain valve generally includes a button, a pressing rod 41', a connecting rod 42', a lifting arm 32', and a lifting pipe 3', such as figure 1 As shown, press the button, press the button to press down one end of the pressure rod 41', the other end of the pressure rod 41' lifts up and pulls the connecting rod 42' to move upward, and the connecting rod 42' pulls the lifting tube through the horizontally arranged lifting arm 34' 3' move upwards together, the riser 3' guides and cooperates with the valve body 1' and drives the valve disc 31' to move upwards to open the drain port of the drain valve to realize the draining process. [0003] In the above-mentioned prior art, the link-type lifting mechanism composed of the pressing rod 41' and the connecting rod 42' ensures that the l...
