DETAIL DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to Figs. 1 and 2, illustrating a bathroom quick coupling according to an embodiment of the present invention. The bathroom quick coupling comprises a main body 1 in tubular shaped, the main body 1 has a water source end 11 for connecting to running water and a connecting end 12 for connecting to an external pipe. A valve 13 is between the water source end 11 and the connecting end 12 of the main body 1 for controlling the water stream.
Moreover, a hollow room 2 is recessed from the connecting end 12 of the main body 1 to form an opening 21. The hollow room 2 has at least one annular groove 22, and a sealing ring 221 is assembled in each of the at least one sealing ring 22.
Hence, when the external pipe is inserted into the hollow room 2, the external pipe is enclosed by the sealing ring 221 to perform sealing. A portion of the hollow room 2 near the opening 21 has a thin section 23, and the hollow room 2 has an expanded section 24, the expanded section 24 is connected to a first side of the thin section 23 distant from the opening 21, and an inner diameter of the expanded section 24 is greater than an inner diameter of the thin section 23. The inner diameter of the expanded section 24 gradually increases in a direction opposite to
4 the opening 21. Furthermore, a second side of the thin section 23 near the opening 21 is connected to the guiding section 25, and an inner diameter of the guiding section 25 gradually increases in a direction toward the opening 21.
On the other hand, the hollow room 2 has a positioning clamp 3 for positioning with the external pipe. The positioning clamp 3 has a base 31 in ring shaped to surround a channel 311. A plurality of clamping blocks 32 is extending from one side of the base 31. The clamping blocks 32 surround the channel 311 of the base 31 and are arranged spacedly with each other by gaps 33. Each of the clamping blocks 32 is are slightly deformable within the gap 33 between adjacent clamping blocks 32. A reverse-tooth portion 321 is protruding from an inner side of each of the clamping blocks 32 for stably engaging with the external pipe, and a protruding portion 322 is on an outer side of each of the clamping blocks 32. An outer diameter D1 of the positioning clamp 3 is a distance between outer peripheries of the protruding portions 322 of two opposite clamping blocks 32, and the outer diameter D1 of the positioning clamp 3 is greater than the inner diameter D2 of the thin section 23.
The positioning clamp 3 is engaged in the hollow room 2 from the opening 21.
In detail, in the operation, since the outer diameter D1 of the positioning clamp 3 is greater than the inner diameter D2 of the thin section 23, the protruding portions 322 of the clamping blocks 32 are firstly put on the guiding section 25. Next, during placing the positioning clamp 3 in the hollow room 2, the clamping blocks 32 are guided by the guiding section 25 so as to come close to each other, thus the outer diameter D1 of the positioning clamp 3 is temporarily reduced to allow the positioning clamp 3 to enter into the thin section 23. Next, after the positioning clamp 3 passes through the thin section 23 and enters into the expanded section 24, the positioning clamp 3 is no more compressed by the thin section 23 and thus the clamping blocks 32 are resiliently recovered to the original positions. At this moment, since the outer diameter D1 of the positioning clamp 3 is again greater than the inner diameter D2 of the thin section 23, the positioning clamp 3 is engaged in the hollow room 2.
Accordingly, when an external pipe is connected to the bathroom quick coupling according to the embodiment, as shown in Fig. 3, the external pipe 4 is inserted into the hollow room 2 from the opening 21 and through the channel of the base 31 of the positioning clamp 3. Then, the clamping blocks 32 are expanded outwardly in the expanded section 24 by the external pipe 4, and the external pipe 4 is clamped by the resilient force of the clamping blocks 32, so that the external pipe 4 is positioned. Furthermore, the reverse-tooth portions 321 of the clamping blocks 32 can closely engage with the external pipe 4 to generate a greater friction force. Therefore, the external pipe 4 can be stably connected to the connecting end 12 of the main body 1.
As above, the invention has fewer components, as compared with the conventional. Moreover, when a user tends to connect an external pipe 4 with the coupling, the external pipe 4 is inserted into the connecting end 12 and the external pipe 4 can be automatically engaged with the positioning clamp 3. Therefore, the user can perform the operation in an easy and convenient manner, facilitating the assembling of the bathroom components.
On the other hand, the hollow room 2 has a positioning clamp 3 for positioning with the external pipe. The positioning clamp 3 has a base 31 in ring shaped to surround a channel 311. A plurality of clamping blocks 32 is extending from one side of the base 31. The clamping blocks 32 surround the channel 311 of the base 31 and are arranged spacedly with each other by gaps 33. Each of the clamping blocks 32 is are slightly deformable within the gap 33 between adjacent clamping blocks 32. A reverse-tooth portion 321 is protruding from an inner side of each of the clamping blocks 32 for stably engaging with the external pipe, and a protruding portion 322 is on an outer side of each of the clamping blocks 32. An outer diameter D1 of the positioning clamp 3 is a distance between outer peripheries of the protruding portions 322 of two opposite clamping blocks 32, and the outer diameter D1 of the positioning clamp 3 is greater than the inner diameter D2 of the thin section 23.
The positioning clamp 3 is engaged in the hollow room 2 from the opening 21.
In detail, in the operation, since the outer diameter D1 of the positioning clamp 3 is greater than the inner diameter D2 of the thin section 23, the protruding portions 322 of the clamping blocks 32 are firstly put on the guiding section 25. Next, during placing the positioning clamp 3 in the hollow room 2, the clamping blocks 32 are guided by the guiding section 25 so as to come close to each other, thus the outer diameter D1 of the positioning clamp 3 is temporarily reduced to allow the positioning clamp 3 to enter into the thin section 23. Next, after the positioning clamp 3 passes through the thin section 23 and enters into the expanded section 24, the positioning clamp 3 is no more compressed by the thin section 23 and thus the clamping blocks 32 are resiliently recovered to the original positions. At this moment, since the outer diameter D1 of the positioning clamp 3 is again greater than the inner diameter D2 of the thin section 23, the positioning clamp 3 is engaged in the hollow room 2.
Accordingly, when an external pipe is connected to the bathroom quick coupling according to the embodiment, as shown in Fig. 3, the external pipe 4 is inserted into the hollow room 2 from the opening 21 and through the channel of the base 31 of the positioning clamp 3. Then, the clamping blocks 32 are expanded outwardly in the expanded section 24 by the external pipe 4, and the external pipe 4 is clamped by the resilient force of the clamping blocks 32, so that the external pipe 4 is positioned. Furthermore, the reverse-tooth portions 321 of the clamping blocks 32 can closely engage with the external pipe 4 to generate a greater friction force. Therefore, the external pipe 4 can be stably connected to the connecting end 12 of the main body 1.
As above, the invention has fewer components, as compared with the conventional. Moreover, when a user tends to connect an external pipe 4 with the coupling, the external pipe 4 is inserted into the connecting end 12 and the external pipe 4 can be automatically engaged with the positioning clamp 3. Therefore, the user can perform the operation in an easy and convenient manner, facilitating the assembling of the bathroom components.
