Description

Technical Field

[0001] The present invention relates to the technical field of drains, and in particular to a mechanical connecting rod opening and closing type drain. Background Art

[0002] Currently, most drains on the market are divided into pop-up drains or flip-up drains, which are widely used in bathtubs and washbasins in daily life as drainage devices for drainage.

[0003] Among them, the bouncing drain is a drain with an elastic mechanism that controls the sealing cover in the water channel, so that the sealing cover can be controlled to open and close the water channel by pressing the elastic mechanism. This drain has a complex structure, especially the elastic mechanism in the water channel will block the drainage, resulting in the water channel cannot be fully opened, resulting in insufficient drainage, affecting the drainage flow and efficiency.

[0004] There are two types of flip-up drains. One of them is to provide a flip-up sealing plate in the water channel, and open and close the water channel by flipping the sealing plate. The structure of this drain is too simple, and the sealing plate cannot maintain a vertical flip state for a long time. When it is slightly impacted by the water flow, it will flip horizontally to close the water channel by itself, which is extremely inconvenient to use; the other is a flip-up drain disclosed in patent No. 202022408475.8, which is directly provided with a hinged seat for hinged sealing cover above the drain body. When in use, the sealing cover flips on the hinged seat and covers the water inlet. Although this method can completely open the water channel, if it is used frequently for a long time, its sealing effect is not easy to guarantee, and the sealing cover and the hinged seat are always located on the outside of the drain, which not only takes up too much space, but is also not beautiful enough, and the product lacks market competitiveness. Summary of the Invention

[0005] The present invention provides a mechanical connecting rod opening and closing type drain, which overcomes the shortcomings of the background art and adopts the following technical solutions:

[0006] A mechanical linkage opening and closing water drain comprises a water drain body, a sealing cover and a mechanical linkage; the water drain body has a water passage; the bottom of the mechanical linkage is hinged to the water drain body; the sealing cover is installed on the water drain body in the water passage through the mechanical linkage; the water drain body comprises a water passage base, which is slidably arranged in the water passage, and the mechanical linkage is hinged to the water passage base in the water passage; a receiving cavity is provided in the water passage; when the sealing cover blocks the water passage, the mechanical linkage is received in the receiving cavity; the sealing cover is swung to the outside of the water passage through the mechanical linkage to open the water passage.

[0007] Preferably, the mechanical connecting rod is a single connecting rod or a multi-connecting rod; the sealing cover is rotatably connected to the top of the mechanical connecting rod.

[0008] Preferably, the sealing cover is rotatably connected to the top of the multi-link via a universal ball joint.

[0009] Preferably, the receiving cavity is formed on the water overflow base.

[0010] Preferably, the water flow base is extended with a plurality of connecting plates, and the plurality of connecting plates form a filtering surface in the water flow channel.

[0011] Preferably, the gaps between the plurality of connecting plates are adjacently arranged on the lower side of the water flow base to enclose and form the filtering surface.

[0012] Preferably, it further comprises an anti-odor cover, which is hinged to the drain body.

[0013] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The technical solution of the present invention has the effects of small space occupancy and high drainage efficiency. A receiving cavity is provided in the water passage, and a sealing cover is installed on the drain body in the water passage through a mechanical connecting rod. After the sealing cover blocks the water passage, the mechanical connecting rod can be hidden in the receiving cavity, which greatly reduces the space occupied. When the water passage is opened, the sealing cover can be driven by the mechanical connecting rod to swing outside the water passage to fully open the water passage, facilitate unimpeded drainage, and improve drainage flow and drainage efficiency.

[0015] (2) The bottom of the mechanical connecting rod is hinged or slidably mounted on the drain body, so that the sealing cover can be driven to swing back and forth between the inside and outside of the water channel by controlling the rotation or sliding of the mechanical connecting rod, thereby opening or closing the water channel. The structure is simple and the operation is convenient.

[0016] (3) When the mechanical link is a single link, the bottom of the single link is hinged to the drain body, and the top is rotatably connected to the sealing cover, so that the sealing cover can be driven to swing out of the water channel through the rotation of the single link. The sealing cover can then rotate on its own at the top of the single link to adjust the direction of the sealing cover and ensure the steering flexibility of the sealing cover.

[0017] (4) When the mechanical link is a multi-link, the multi-link consists of two single rods, wherein the bottom rod of the front single rod is hinged to the drain body, and the top of the rear single rod is hinged to the sealing cover. The front single rod is used to rotate, and after the sealing cover is driven to swing outside the water channel, the sealing cover can be rotated in more directions by itself through the rear single rod, thereby increasing the adjustment direction of the sealing cover and further improving the steering flexibility of the sealing cover when it is outside the water channel.

[0018] (5) The sealing cover is rotatably connected to the top of the multi-link through a universal ball joint, so that after the sealing cover is swung out of the water channel, it can be universally rotated through the universal ball joint, further increasing the adjustment direction of the sealing cover, making it easier for users to use.

[0019] (6) The water-passing base is slidably mounted in the water-passing channel, and the mechanical connecting rod is hinged to the water-passing base in the water-passing channel. When the whole is disassembled and assembled, the mechanical connecting rod can be directly slid in and out of the water-passing channel quickly through the water-passing base, making disassembly and assembly and subsequent cleaning extremely convenient, saving time and effort.

[0020] (7) A plurality of connecting plates extend from the lower side of the water flow base, and the connecting plates form a filtering surface in the water flow channel. When the water flows into the water flow base, it can continue to flow for a certain distance and impact the filtering surface for appropriate buffering and filtering.

[0021] (8) The gaps between the connecting plates are adjacent to the lower side of the water-passing base to form a filtering surface. When the water flows into the water-passing base, it can be directly discharged through the gaps between the connecting plates and the formed filtering surface. This not only has a certain filtering effect, but also can better ensure the water flow rate and prevent the drainage efficiency from being affected by too small a discharge volume.

[0022] (9) The odor-proof cover is hinged on the drain body to prevent the odor from the sewer pipe from overflowing through the water channel. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] First embodiment

[0042] This embodiment provides a mechanical linkage opening and closing drain, comprising a drain body 1, a sealing cover 2A, and a mechanical linkage. The drain body 1 has a water passage 11 extending throughout the drain body. The water inlet end of the water passage 11 has a receiving chamber, in which a sealing cover 2A is disposed, and an odor-proof cover 7 is hingedly connected to the water outlet end. The bottom of the mechanical linkage is hingedly connected to the drain body 1 within the water passage 11, and the top is assembled with the sealing cover 2A at the water inlet end. When opening the water passage 11, the mechanical linkage can rotate and drive the sealing cover 2A to swing to the outside of the water passage 11, fully opening the water inlet end of the entire water passage 11. When blocking the water passage 11, the mechanical linkage can rotate and drive the sealing cover 2A to block the water passage 11, while the mechanical linkage is automatically stored in the receiving chamber for concealment, thereby reducing the occupied area. In other embodiments, the bottom of the mechanical connecting rod may also be slidably disposed on the drain body 1 in the water passage 11 to drive the sealing cover 2A to open and close inside and outside the water passage 11 .

[0043] In this embodiment, the drain body 1 includes a water-passing base 12. A limiting step is provided in the water-passing channel 11. The water-passing base 12 is slidably mounted against the limiting step of the water-passing channel 11 for limiting position. The water-passing base 12 has a hinge hole at one end and a clearance groove at the other end.

[0044] In this embodiment, the receiving cavity is formed on the water flow base 12 and is close to the water inlet end of the water flow channel 11 .

[0045] In this embodiment, the mechanical linkage is a single-link structure, consisting of a single first link 31A. The bottom of the first link 31A is hinged to a hinge hole at one end of the water-passing base 12, and the top is hinged to the sealing cover 2A. When the sealing cover 2A blocks the water-passing channel 11, the top of the first link 31A is hidden within a recess at the other end of the water-passing base 12, allowing it to be contained within the receiving cavity and perpendicular to the water-passing channel 11. When the water-passing channel 11 is opened, the first link 31A rotates around its bottom, gradually becoming parallel to the water-passing channel 11, and the sealing cover 2A disengages from the water inlet end of the water-passing channel 11, placing the sealing cover 2A outside the water-passing channel 11, thereby opening the water-passing channel 11. When the sealing cover 2A swings outside the water-passing channel 11, it can rotate on the top of the first link 31A, automatically adjusting its direction.

[0046] In this embodiment, because the mechanical connecting rod is located inside the water channel 11, when the mechanical connecting rod rotates and drives the sealing cover 2A to rotate, the sealing cover 2A will inevitably collide with the water base 12 (see Figure 3 At this time, if the first connecting rod 31A directly rotates to drive the sealing cover 2A to rotate, the sealing cover 2A will abut against the inner wall of the water-passing base 12 during the rotation process, resulting in the rotation of the first connecting rod 31A being blocked). Therefore, when opening the water-passing channel 11, the sealing cover 2A needs to rotate a certain angle at the top of the first connecting rod 31A as the first connecting rod 31A rotates, and is dislocated from the inner wall of the water-passing base 12 so that the sealing cover 2A can be removed from the water-passing channel 11. Otherwise, if the sealing cover 2A is directly driven to rotate by the rotation of the first connecting rod 31A, the sealing cover 2A will inevitably abut against the water-passing base 12, thereby limiting the rotation of the first connecting rod 31A (see Figure 4 When the first connecting rod 31A rotates and drives the sealing cover 2A to rotate, the sealing cover 2A also rotates a certain angle on the top of the first connecting rod 31A to prevent the sealing cover 2A from touching the inner wall of the water base 12 during the rotation of the first connecting rod 31A, so as to achieve the following Figure 5 Opening effect of sealing cover 2A).

[0047] In this embodiment, the lower side of the water flow base 12 includes a plurality of extended connecting plates, which are arranged adjacent to the circumferential gaps of the water flow base 12 and below the water flow base 12 to enclose a filtering surface.

[0048] In this embodiment, a cone 5 is fixedly mounted on each of the two connecting plate water-passing bases 12. Multiple cones 5 are evenly spaced around the circumference, forming a vertical water-passing channel 11 filtering surface. When water flows through the water-passing bases 12, it is discharged directly through the gaps between the connecting plate water-passing bases 12, increasing the water flow rate. Furthermore, foreign matter is filtered and blocked through the gaps between the connecting plates and the filtering surface.

[0049] In this embodiment, a sealing plug 6 is further included. The sealing plug 6 is fixed on the sealing cover 2A so that when the sealing cover 2A is blocked on the water passage 11, the water passage 11 can be further sealed by the sealing plug 6 to prevent water leakage.

[0050] In this embodiment, the odor-proof cover 7 is hinged on the lower side of the water flow base 12 to prevent the odor from the sewer pipe from overflowing through the water flow channel 11. When the sealing plug 6 is blocked on the water flow channel 11, the sealing plug 6 can also achieve a double sealing effect with the odor-proof cover 7, further improving the sealing performance.

[0051] The working principle and use process of the present invention: During installation, Figure 1 The entire product is installed in the drain hole; when it is necessary to drain water, manually grasp the sealing plug 6, and drive the sealing cover 2A to rotate 90 degrees in conjunction with the first connecting rod 31A in the water channel 11 through the sealing plug 6, until the first connecting rod 31A is parallel to the water channel 11 and vertically rests on the inner wall of the water base 12 for positioning and fixing, that is, the sealing cover 2A is completely swung to the outside of the water channel 11 (see Figure 4 and Figure 5 ), the water passage 11 is fully opened, allowing water to flow into the water passage 11 from the water inlet end. Within the water passage 11, water is simultaneously filtered by the connecting plate 121 and the filter surface on the water passage base 12. The water then continues to flow, opening the odor-proof cover 7 and entering the sewer pipe. To block the water passage 11, simply manually press the sealing plug 6, driving the sealing cover 2A to rotate the first connecting rod 31A 90 degrees until the first connecting rod 31A is vertically accommodated within the receiving chamber and positioned parallel to the water passage base 12. This completes the blocking of the water passage 11 by the sealing plug 6. Therefore, the present invention not only achieves a satisfactory sealing effect, but also fully opens the water passage 11 during use, improving the water flow rate and efficiency, and facilitating smooth drainage.

[0052] See also Figures 7 to 10

[0053] Second embodiment

[0054] The difference between this embodiment and the first embodiment is that the mechanical connecting rod is a multi-link structure, which includes two mutually hinged first connecting rods 32A and second connecting rods 32B, the bottom of the first connecting rod 32A is hinged to the water flow base 12, and the top is hinged to the second connecting rod 32B; the bottom of the second connecting rod 32B is hinged to the top of the first connecting rod 32A, and the top is hinged to the sealing cover 2B; the top of the second connecting rod 32B has a universal ball head, which is hinged to the sealing cover 2B, so that when the sealing cover 2B swings to the outside of the water flow channel 11, the sealing cover 2B can achieve universal rotation through the universal ball head.

[0055] In this embodiment, a connecting sleeve 4 is provided between the universal ball joint and the sealing cover 2B, and the universal ball joint is mounted on the sealing cover 2B through the connecting sleeve 4 to achieve assembly and fixation of the two.

[0056] In this embodiment, as the first connecting rod 32A rotates, the sealing cover 2B can be universally displaced relative to the inner wall of the water-passing base 12 to prevent contact between the two. When the first connecting rod 32A drives the sealing cover 2B to the outside of the water-passing channel 11, the first connecting rod 32A remains stationary, while the second connecting rod 32B and the sealing cover 2B can rotate independently, allowing for multiple adjustments and greater user convenience.

[0057] The above description and embodiments are intended to explain the scope of protection of the present invention, but do not constitute a limitation thereto. Modifications, equivalent substitutions, or other improvements to the embodiments of the present invention or portions thereof that can be obtained by a person of ordinary skill in the art through logical analysis, reasoning, or limited experimentation based on the teachings of the present invention or the above embodiments, combined with common knowledge, ordinary technical knowledge in the field, and / or prior art, should all be included within the scope of protection of the present invention.
