Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a quick-connect tee. Background Art

[0002] Three-way tees are commonly found in water outlet pipes in kitchens or bathrooms. They can split one water route into two water routes to supply water to more water-using equipment or products. Most tees on the market adopt an integrated structure. However, there are also some detachable tees that can be freely switched from three-way to two-way through disassembly and assembly. These detachable tees are used in some equipment with upgradeable functions, such as the upgrade of toilet functions, from only having a flushing function to having a foaming function. At this time, it is necessary to disassemble and transform the original water route and switch the original two-way joint to a three-way. At present, there are not many detachable tees, and most of them have complex structures for disassembly and assembly, which brings inconvenience to the above-mentioned upgrading and transformation operations. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an assembled three-way structure with a simple structure.

[0004] A quick-connect tee comprises a first water-passing part, a second water-passing part and a quick-install limiting part.

[0005] The first water-passing member is provided with a first pair of joints, and the outer ring of the first pair of joints is provided with a limiting groove. The second water-passing member is provided with a second pair of joints, and the outer periphery of the second pair of joints is provided with a through insertion hole. One of the first water-passing member and the second water-passing member is also provided with a first water-passing joint and a second water-passing joint.

[0006] The quick-install limiter comprises a limit ring, the limit ring is inserted into the insertion hole of the second pair of joints, and an elastic structure is arranged between the quick-install limiter and the second water-passing member.

[0007] During assembly, the first pair of joints are inserted into the second pair of joints and pass through the limiting ring. At this time, the elastic structure is compressed. When the limiting groove and the limiting ring are aligned, the elastic structure pushes the limiting ring to withdraw from the insertion hole and forces the inner ring of the limiting ring to be stuck in the limiting groove of the first pair of joints, thereby realizing rapid assembly of the first water-passing part and the second water-passing part.

[0008] The utility model can realize the rapid assembly of the first water passing part and the second water passing part by setting the quick-install limit part, the insertion hole and the limit groove. It has the advantages of simple structure and fast disassembly and assembly speed.

The outer periphery of the second water-passing part is provided with a protective groove for accommodating the quick-release seat, and the notch of the protective groove exceeds or is flush with the pressing surface, which can avoid accidentally touching the pressing surface and causing the two water-passing parts to be separated by mistake.

[0013] Preferably, in order to prevent the quick-release limit piece from falling off the second water-passing piece when the two water-passing pieces are separated, the outer periphery of the limit ring is provided with an undercut facing the quick-release seat, and the interior of the insertion hole is provided with a limit step facing away from the quick-release seat, and after the limit ring clamps the limit groove of the first pair of joints, the undercuts pass through the limit steps and press against each other.

[0014] Preferably, the inner circle of the limiting ring is composed of two semicircles, and the diameter of the semicircle close to the quick-release seat is larger than the outer diameter of the first pair of joints, making it easy for the second pair of joints to pass through, while the diameter of the other semicircle is equal to the outer diameter of the limiting groove, and the two semicircles are transitioned by an arc.

[0015] Preferably, a water stop valve is provided in the first pair of joints of the first water passing member. The second pair of joints is butted against the first pair of joints and the water stop valve is pushed open, and the first water passing member is connected to the second water passing member, or the second pair of joints is separated from the first pair of joints and the water stop valve is released, and the water stop valve blocks the first pair of joints, so that the water is automatically shut off when the two water passing members are separated, thereby avoiding water overflow when the two water passing members are separated.

[0016] Preferably, a compression spring is provided in the first pair of joints, and after the second pair of joints is separated from the first pair of joints, the compression spring pushes the water stop valve to block the first pair of joints, thereby improving the blocking ability of the water stop valve.

DETAILED DESCRIPTION

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0039] See also Figures 1 to 10 A quick-connect tee comprises a first water-passing part 1, a second water-passing part 2 and a quick-install limiter 3.

[0040] The first water-flowing member 1 is provided with a first pair of joints 11, and the outer ring of the first pair of joints 11 is provided with a limiting groove 111. The second water-flowing member 2 is provided with a second pair of joints 21, and the outer periphery of the second pair of joints 21 is provided with a through insertion hole 211. One of the second water-flowing members 2 is also provided with a first water-flowing joint 22 and a second water-flowing joint 23, so as to realize one way into two ways. In one embodiment, the second water-flowing joint 23 is arranged on the periphery of the second pair of joints 21 to form a side joint with a diameter of 1 / 4 inch, which is directly connected to a 1 / 4 inch quick joint, thereby improving the convenience of assembly, and can supply water for the toilet foaming function or the bidet, and the first water-flowing member 1 is arranged at the end of the second water-flowing member 2, and can be fixedly assembled with one end of the toilet flushing pipe, thereby reducing the subsequent assembly steps.

[0041] The quick-install limiter 3 includes a limit ring 31 , which is inserted into the insertion hole 211 of the second joint 21 . An elastic structure is also provided between the quick-install limiter 3 and the second water-passing member 2 .

[0042] In one embodiment, the quick-install limiter 3 further includes a quick-install seat 32, and the limit ring 31 is arranged at one end of the quick-install seat 32 facing the second pair of joints 21. The elastic structure is arranged between the second pair of joints 21 and the quick-install seat 32. The elastic structure is an elastic sheet 321, which is arranged at one end of the quick-install seat 32 facing the second pair of joints 21 and supports the outer periphery of the second pair of joints 21, and has a simple structure.

[0043] Preferably, the inner circle of the limiting ring 31 is composed of two semicircles, and the diameter of the semicircle close to the quick-release seat 32 is larger than the outer diameter of the first pair of joints 11, so that the second pair of joints 21 can pass through easily, while the diameter of the other semicircle is equal to the outer diameter of the limiting groove 111, and the two semicircles are transitioned by an arc. In addition, a conical surface 112 is provided between the end of the first pair of joints 11 and the limiting groove 111, and when the first pair of joints 11 is inserted into the second pair of joints 21, the limiting ring 31 can be automatically pushed open by the conical surface 112.

[0044] In order to prevent the quick-install limit member 3 from falling off the second water-passing member 2 when the two water-passing members are separated, in another embodiment, the outer periphery of the limit ring 31 is provided with an undercut 311 facing the quick-install seat 32, and the interior of the insertion hole 211 is provided with a limit step 2111 away from the quick-install seat 32. After the limit ring 31 clamps the limit groove 111 of the first pair of joints 11, the undercut 311 passes through the limit step 2111 and presses against each other.

[0045] Based on the above embodiment, in one embodiment, the end of the quick-release seat 32 away from the second joint 21 forms a pressing surface 322, and the user can actively press to separate the two water-spreading parts. In addition, the outer periphery of the second water-spreading part 2 is provided with a protective groove 24 for accommodating the quick-release seat 32, and the notch of the protective groove 24 exceeds or is flush with the pressing surface 322, which can avoid accidentally touching the pressing surface 322, causing the two water-spreading parts to be separated by mistaken operation.

[0046] In one embodiment, a water stop valve 12 is provided in the first pair of joints 11 of the first water flow component 1. The second pair of joints 21 and the first pair of joints 11 are connected to each other and push the water stop valve 12 open, so that the first water flow component 1 and the second water flow component 2 are connected, or the second pair of joints 21 and the first pair of joints 11 are separated and the water stop valve 12 is released, and the water stop valve 12 blocks the first pair of joints 11, so that the water is automatically shut off when the two water flow components are separated, and water overflow can be avoided when the two water flow components are separated. Preferably, a compression spring 13 is provided in the first pair of joints 11, and after the second pair of joints 21 and the first pair of joints 11 are separated, the compression spring 13 pushes the water stop valve 12 to block the first pair of joints 11, thereby improving the blocking ability of the water stop valve 12. In this embodiment, Fig.11 The first water flow member 1, the compression spring 13 and the water stop valve 12 can be used as an independent component. During assembly, the compression spring 13 and the water stop valve 12 equipped therewith are sequentially installed into the water outlet joint of the water outlet pipe, and then the first water flow member 1 is connected to the water outlet joint of the water outlet pipe, and the push rod of the water stop valve 12 is extended from the first pair of joints 11 of the first water flow member 1. By installing the first water flow member 1, the water outlet joint of the original water outlet channel becomes a joint that needs to press the push rod of the water stop valve 12 to discharge water.

[0047] During assembly, the first pair of joints 11 is inserted into the second pair of joints 21 and passes through the limiting ring 31. At this time, the elastic structure is compressed. When the limiting groove 111 and the limiting ring 31 are aligned, the elastic structure pushes the limiting ring 31 to withdraw from the insertion hole 211, and forces the inner ring of the limiting ring 31 to be inserted into the limiting groove 111 of the first pair of joints 11, thereby realizing the rapid assembly of the first water-passing member 1 and the second water-passing member 2. During disassembly, it is only necessary to press the quick-release seat 32 to allow the limiting ring 31 to withdraw from the limiting groove 111.

[0048] The utility model can realize the rapid assembly of the first water passing member 1 and the second water passing member 2 by providing the quick-install limit member 3, the insertion hole 211 and the limit groove 111. It has the advantages of simple structure and fast assembly and disassembly speed, and can be widely used in various scenarios requiring waterway upgrades, providing convenience for staff.
