Description

  The present invention can connect the drain outlet at the bottom of a sink of a kind of metal sink and a sink trap, and has a seamless structure, especially without the appearance of a kind of metal sink and easy to clean and clean. The present invention relates to a fixed structure of a sink trap.

Most sinks on the market are metal sinks made of stainless steel so that they can withstand use and are easy to clean or clean. Use a metal sink when washing kitchen dishes, teacups or fruits and vegetables, and usually connect a sink trap above the drain of the metal sink to prevent clogging of the drain pipe, and filter the filter parts in the sink trap Remove things in the drainage with holes or nets.
In consideration of cost, the manufacture of metal sinks generally employs a thin shell (thin wall) sink body formed by sheet metal processing technology. Since the sink bottom wall is thin, it is difficult to fix the sink trap at the drain end of the drain. The structure of a conventional sink trap is that the sink trap protrudes from a drain outlet at the bottom of the sink in the sink in the Taiwanese utility model M383593 “Improved structure of sink sink sink sink”.
Stopped on the surface of the sink bottom by the edge of the sink trap and combined with a water stop gasket, it is located at the end of the sink and is screwed and fixed with the male thread of the sink trap using a single fixing ring to drain the sink trap. Secure on the mouth. Regardless of the thickness of the water stop gasket or in combination with the water stop gasket, a gap is formed between the installation edge and the surface of the sink bottom. In view of the fact that the gap is clogged with dirt (molds and off-flavors are generated), is difficult to clean, and affects the beauty and hygiene of the sink, further improvement is necessary.

Taiwan Utility Model No. M383593 JP2013-104202A

  In order to solve the disadvantages of the known structure, the main object of the present invention is to provide a fixing structure for a sink trap without a metal sink joint.

Form. Thereby, the sink trap is fixed to the connection sleeve, and the effect of preventing liquid from leaking out is reached.

Another object of the present invention is to provide a kind of sink trap fixing structure without a metal sink joint, and the frame setting part of the sink trap forms one frame body. The fixed cover is assembled to the frame installation portion. One receiving ring for supporting the lower edge of the frame installation portion is provided opposite to the lower edge of the frame body of the frame installation portion.
When the female screw of the fixed cover is screwed with the male screw of the connecting sleeve, the fixed cover and the connecting sleeve are closed tightly by checking the frame setting part of the sink trap with the receiving ring of the fixed cover and bringing it close to the bottom end of the connecting sleeve. Even if the sink trap does not rotate with the fixed cover, the sink trap frame can be connected to or disconnected from the metal sink frame ring, and the sink trap can be assembled on the drain of the metal sink. Or it is convenient to disassemble.

  Still another object of the present invention is to provide a fixing structure for a sink trap without a kind of metal sink joint, and the fixing cover is a locking part having a single internal thread, and the internal thread The lock part of a part of the lower edge of the sink trap is integrally connected to the outer edge of the frame setting portion of the sink trap, so that the sink trap and the fixed cover can be integrally injection-molded using a plastic material, Processing costs can be reduced.

  According to the structure of the present invention, the surface of the drain outlet of the sink bottom of the metal sink reaches the effect of no seam or no gap, and the hygienic effect that the metal sink is beautiful and easy to clean is improved.

It is a structural exploded view of the present invention. It is a cross-sectional structure schematic when the sink trap of this invention is decomposed | disassembled. FIG. It is a structure decomposition | disassembly solid view of another Example of this invention. 4 is an assembly cross-sectional structure schematic diagram of another embodiment of the present invention.

  Hereinafter, the structure, features, and effects of the present invention will be described in detail with reference to the best embodiments and drawings.

The present invention is a fixed structure of a sink trap without a metal sink joint. As shown in FIGS. 1, 2, and 3, one drain port 12 is provided in the sink bottom 11 of one stainless metal sink 10. One sink trap 20 is connected to the drain port 12, one staircase tank 21 is provided inside the sink trap 20, and one drainage pipe (not shown) can be connected to the bottom end of the staircase tank 21. A drain pipe connection 22 is provided.
A feature of the present invention is that the sink bottom 11 of the metal sink 10 is integrally formed with a single frame ring 13 extending outwardly from the tank wall of the sink bottom 11 around the drain port 12. One connection sleeve 30 is fixed to the outer periphery of the frame ring 13, and one male screw 31 is formed on the outer edge of the connection sleeve 30. The open end of the staircase tank 21 of the sink trap 20 is opposed to the bottom end of the connection sleeve 30 to form one frame installation portion 23.
One fixed cover 24 is provided on the outer edge of the frame installation portion 23, and one internal thread 241 is formed inside the fixed cover 24 to face the external thread 31 of the connection sleeve 30, and the internal thread 241 and the connection sleeve 30 are formed.
