Description

Technical Field

[0001] The utility model relates to a drain rod structure. Background Art

[0002] In containers such as bathrooms, bathtubs, washbasins or washstands, it is desired to provide a drainer, also known as a drain rod device, to achieve water storage or drainage in the container. Such a drain rod device usually presents as a linkage device of a drain plug. For example, in an existing drain rod device, the container is connected to a drain pipe through an outflow port, and a drain plug is arranged near the outflow port. The drain plug is connected to one end of an operating rod such as a lever member, and the other end of the lever member is connected to a downwardly extending pull rod member. Thus, the drain plug can be moved between a position closing and opening the outflow port by operating the pull rod member, and water outflow or drainage of the container such as a bathroom sink, bathtub, washbasin or washstand can be achieved.

[0003] For example, in the Chinese utility model patent authorization announcement number CN219450930U, named as a quick-installation lifting drain rod and washbasin, its locking member penetrates upward from below and is fixed on the integral flange drain rod body, above the first mounting hole, and the water stop plug is inserted into the integral flange drain rod body from top to bottom; the rotating rod assembly passes through the accommodating cavity, and its assembly part is at least partially accommodated in the accommodating cavity. The accommodating cavity is coaxially arranged with the first mounting hole, and the assembly part forms a seal with the first mounting hole and the accommodating cavity. The part of the rotating rod assembly passing through the accommodating cavity is inserted into the integral flange drain rod body through the first mounting hole; an installation part is arranged on the outer side wall of the accommodating cavity, and the rotating part is buckled on its outer end from the other outer side surface of the integral flange drain rod body, and the second mounting holes on the rotating part are respectively assembled with the installation part. It can be seen therefrom that its flange drain rod body is integral, and the most common one is a fully metal drain rod body. However, for an integral drain rod body, when surface treatment is carried out on the flange, the entire drain rod body needs to be surface-treated, which is troublesome in operation. At the same time, the integral drain rod body cannot meet the customer's demand for semi-metal. Summary of the Utility Model

[0004] The utility model provides a drain rod structure, which overcomes the deficiencies in the background art. The technical solution adopted by the utility model to solve its technical problems is as follows:

[0033] Please refer to Figures 1 to 6 , a preferred embodiment of a drain rod structure. The described drain rod structure is applicable to a washbasin. The drain rod structure includes a drain rod assembly 100 for draining water, a locking member 200 for fixing the drain rod assembly 100, and a valve core 300.

[0034] The drain rod assembly 100 is provided with a drain channel 101, and includes a flange 110, a drain rod body 120 and a tail pipe 130. The flange 110 is detachably connected to the top end of the drain rod body 120. The tail pipe 130 is sleeved on the lower end of the drain rod body 120. The drain channel 101 sequentially penetrates through the flange 110, the drain rod body 120 and the tail pipe 130.

[0035] In this embodiment, the rod body 120 is made of metal, and the tail pipe 130 is made of plastic. The tail pipe 130 is threadedly connected to the rod body 120, that is, a combination of a metallic texture and a plastic texture. Alternatively, as required, the rod body 120 is made of metal, and the tail pipe 130 is made of metal. The tail pipe 130 and the rod body 120 can be connected by threading or welding. The rod assembly 100 decomposes the integral rod body in the prior art into a flange 110, a rod body 120, and a tail pipe 130. Thus, when surface treatment is performed on the flange 110, only the flange 110 needs to be treated separately, and the rod body 120 and the tail pipe 130 do not need to be treated. This not only makes the treatment more convenient but also saves treatment costs. Moreover, the tail pipe 130 can be selected from metal or plastic materials according to customer needs, and the rod body 120 can be used as a general component, saving costs.

[0036] In this embodiment, an overflow port 102 communicating with the drainage channel 101 is provided on the side wall of the rod body 120.

[0037] The locking member 200 is sleeved on the outer periphery of the rod body 120 or the tail pipe 130 and abuts against the bottom surface of the washbasin.

[0038] In this embodiment, the locking member 200 is a locking nut. The locking nut is in the shape of a hollow inverted trapezoid. An internal thread is provided on the inner wall of the bottom end of the locking nut, and an external thread is provided on the outer periphery of the rod body 120. The locking member 200 is locked to the rod body 120 through the screwing fit of the internal thread and the external thread. As Figure 2 shown, the locking member 200 is located above the tail pipe 130. At this time, the top surface of the tail pipe 130 can be used as a limiting surface for the locking member 200 to prevent the locking member 200 from falling off downward.

[0039] In this embodiment, the rod structure further includes a first conical pad 140 and a second conical pad 150. The first conical pad 140 is sandwiched between the flange 110 and the entrance of the drainage channel 101, and the second conical pad 150 is sandwiched between the exit of the drainage channel 101 and the locking member 200.

[0040] The valve core 300 is detachably installed in the drainage channel 101.

[0041] In this embodiment, the valve core 300 includes a valve seat 310, a valve shaft 320, a push cover 330 and an elastic component. The valve seat 310 includes a water filter base 311 and a fixed rod 312 fixed in the water filter base 311. The valve shaft 320 is hollow, the push cover 330 is installed on the top of the valve shaft 320, and the elastic component is installed in the valve shaft 320. The elastic component is a prior art and will not be described in detail. The bottom end of the valve shaft 320 is movably sleeved on the outer periphery of the fixed rod 312. The bottom end of the valve shaft 320 is movably sleeved on the outer periphery of the fixed rod 312, and the junction of the valve shaft 320 and the fixed rod 312 is open downward, along the direction of the water flow, and is not easy to hide dirt, thereby making the use of the push cover 330 smoother and will not fail.

[0042] In this embodiment, Figure 4 As shown, the water filter base 311 includes a water filter bottom wall 314 with a water filter hole 313 and a water filter peripheral wall 315 surrounding the outer periphery of the water filter bottom wall 314, the fixing rod 312 is fixedly connected to the center of the water filter bottom wall 314, and the water filter peripheral wall 315 is adapted to the inner wall of the drainage channel 101.

[0043] In this embodiment, Figure 6 As shown, the water filter peripheral wall 315 is provided with a plurality of clearance openings 316, and a plurality of elastic clamping protrusions 317, each of which is installed at the corresponding clearance opening 316, and the elastic clamping protrusion 317 is tightly matched with the inner wall of the drainage channel 101. The elastic clamping protrusion 317 is tightly matched with the inner wall of the drainage channel 101, which can ensure that the water filter base 311 and the inner wall of the drainage channel 101 can be relatively fixed and not shaken, and can also ensure that the valve core 300 can be pulled out at any time, which is more convenient to use.

[0044] In this embodiment, Figure 2 As shown, the inner wall of the drainage channel 101 is provided with a limiting step 103 , and the bottom end of the water filter peripheral wall 315 can be reliably abutted against the limiting step 103 , and the limiting step 103 can limit the valve core 300 .

[0045] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
