Problems solved by technology
The cavity can accommodate the swing arm to save space and make it more dwarfed, but the root of the problem still cannot be solved due to the existence of the connecting rod structure
[0005] In summary, the existing drain valve technology has reached a bottleneck in dwarfing the design structure, and if it is not cracked and innovated, it will not be able to adapt to the use of increasingly dwarfed water tanks

Embodiment Construction
[0024] As shown in the figure, an improved structure of the drain valve suitable for low water tanks includes a drain valve main body 8 sealed and installed in the low water tank, and a swing rod 2 that can rotate around the fulcrum 7 is arranged in the drain valve main body 8 One end of the swing rod 2 is a circular arc end face and connected to the button 1, so that when the button 1 collides with the swing rod 2 and is pressed down, it can better maintain an appropriate state and reduce resistance.
[0025] The other end of the swing rod 2 is linked with a lifting rod 6 with a valve plate 9 and realizes the opening and closing of the drainage through the valve plate 9. A traction member 11 is arranged on the oblique side of the upper end of the lifting rod 6, and the traction member 11 is provided with left and right connecting pieces 5 , a clamping chamber 14 is formed between the left and right connecting pieces 5, and the upper surface of the lifting rod 6 and the tractio...

The invention relates to an improved drain valve structure suitable for use in a low water tank. The improved drain valve structure comprises a drain valve body mounted in the low water tank in a sealed mode. An oscillating rod pivotable about a fulcrum is arranged in the drain valve body, one end of the oscillating rod is connected with a key, and the other end of the oscillating rod is linked with a lifting rod with a valve plate through which opening and closing of drainage are achieved. A pulling member is arranged on the oblique side of the upper end of the lifting rod, left and right connecting pieces are arranged on the pulling member, and a clamping cavity is formed between the left and right connecting pieces. The top of each connecting piece is provided with a guiding slot, one end of the oscillating rod is connected in the two guiding slots in an erected mode through a connecting shaft, and the oscillating rod can be accommodated in the clamping cavity when the oscillating rod rotates and rises to the highest point while being linked with the lifting rod. The improved drain valve structure is more precise and high in integration degree, and the overall height of the drain valve can be decreased so as to adapt to water tanks in different heights.
Description
technical field [0001] The invention relates to a water tank drain valve structure, in particular to an improved drain valve structure suitable for low water tanks. Background technique [0002] At present, the height of toilet tanks on the market is relatively high. With the improvement of environmental protection and space saving awareness, the height of the water tank is becoming more and more dwarfed. To ensure the necessary stroke distance when the valve is opened, especially in the field of smart toilets, the overall height of the existing drain valve has been significantly hindered and is not suitable for the dwarf design of the water tank. [0003] In order to adapt to the dwarf design, the patent office announcement number is CN205421460U, named "a dwarf structure suitable for the drain valve of the toilet tank", the upper end of the pull rod of the drain valve is bent and extended to form a pull handle, and the pull handle passes through the connection. The rod is...
