Description

Tube Faucet Adapter

The utility model relates to a tubular faucet adapter.

Generally, the existing adapters for tubular faucets can be roughly divided into two types (as shown in Figures 1, 2, and 5). Figures 1 and 2 show an existing tubular faucet adapter, which consists of an adapter body 1, a rubber bushing 2, and three screws 3. When in use (please refer to Figure 3 ), if the caliber of the tubular faucet 4 is large, the large port diameter 21 of the rubber bushing 2 can be used to secure the tubular faucet 4 (at this time, the caliber of the tubular faucet 4 is larger than the large port diameter of the rubber bushing 2 21 slightly larger), then use a Phillips screwdriver to screw the three screws 3 inward until they touch the tubular faucet 4; The small port diameter 22 is sleeved, and then the above method can be used (as shown in Figure 4), but this structure still has the following disadvantages in use:

1. Because the rubber bushing 2 is only directly inserted into the adapter body 1, if it has been used for a period of time, the socket joint 24 has seeped water, so that water leakage will occur. Moreover, due to the rubber bushing 2 The depth of the large port diameter 31 is limited, so when the angle of the sleeve-type water tap 4 is slightly deviated (that is, the two are not on the same center line), water leakage will also be caused.

2. Since the connectors are all made of metal or electroplated with copper, patina phenomenon or heavy metal substances will often be precipitated during use, so it is more harmful to the health of users.

3. After the existing adapter is set and fixed on the tubular water tap, it is necessary to use a cross screwdriver to screw the screws 3 inward one by one before fixing.

Please refer to Figure 5 again, which is another existing adapter for a tubular faucet, which consists of a rubber adapter body 6, an upper positioning block 7, a lower positioning block 8, a rubber bushing 9 and a telescopic sleeve. The clip 10 is composed of the upper positioning block 7 through the rubber adapter body 6 and the lower positioning block 8 is screwed together, and then the telescopic clip 10 is placed on the rubber adapter body 6 from bottom to top The diameter of the small end is 61. When in use (see Figure 6), if the diameter of the tubular faucet 4 is large, the tubular faucet 4 can be directly installed in the rubber adapter body 6, and then Use a screwdriver to lock the telescopic sleeve 10 on the small end diameter 61 of the rubber adapter body 6; First install the rubber bushing 9 into the rubber adapter body 6, then insert the tubular faucet 4 into the rubber bushing 9, and similarly, use a screwdriver to lock the telescopic sleeve 10, However, this structure still has the following disadvantages in use:

1. Because the upper positioning block 7 and the lower positioning block 8 are fixed in the rubber adapter body 6 by means of a screw connection, rather than integrally formed, water will seep from the joint 62 after a period of use resulting in water leakage.

2. Although the rubber adapter body 6 and the rubber bushing 9 are rubber-like products, the upper positioning block 7 and the lower positioning block 8 are metal products or electroplated with copper, and they will also be used in the same way. There is a patina phenomenon or the precipitation of heavy metal substances, so it also causes harm to the health of users.

3. When the tubular faucet 4 is placed on the rubber adapter body 6 or the rubber bushing 9, it is necessary to use a screwdriver to rotate the screw on the telescopic sleeve clamp 10 to lock the telescopic sleeve clamp.

The main purpose of the present utility model is to provide a tubular faucet adapter, which can be easily assembled and fixed without any tools.

The secondary purpose of this utility model is to provide a tubular faucet adapter, which is made of plastic material. When used, it will not produce any patina phenomenon or worry about the precipitation of heavy metal substances, so that it is more in line with human health. And because the adapter body of the utility model is integrally formed, there will be no water leakage phenomenon.

Another purpose of the present invention is to provide a tubular faucet adapter, which can be assembled on tubular faucets of different diameters only by replacing rubber bushings of different sizes during assembly.

The purpose of this utility model is achieved as follows: a tubular faucet adapter is mainly composed of an upper cover, several rubber bushes, hard washers, and the adapter body. The adapter body is integrally formed, and its upper end has an external thread, which is screwed with the upper cover. There are several convex bodies in the shape of one concave and one convex at the connection with the external thread, arranged at equal intervals around the adapter body, and the convex bodies It is integrally formed on the adapter body, and there is a short external thread at the lower part of the convex body. The external thread is screwed on the water inlet and outlet converter of the water dispenser. The internal diameter of the adapter body is from large to large. Small to small; the upper and lower inner surfaces of the hard gasket are in the shape of a slope; the upper half of the rubber bushing has a larger slope, the lower half has a smaller slope, and the center has a hole; the upper The cover is integrally formed, with a plane on the upper end surface, an arc surface on the plane and the diameter of the outer circle, and an embossed pattern on the surface of the outer circle diameter, and a hole in the center of the upper cover. There is an internal thread larger than the hole at the center of the interior, and an inclined plane is formed between the internal thread and the hole at the center.

The rubber bushing is a softer material and it is available in different sizes.

Rigid gasket Rigid material.

The adapter body is made of plastic.

The adapter structure of the tubular faucet of the present invention has the following characteristics in terms of structure, use, and assembly and sealing of tubular faucets with different diameters and sizes:

1. No screw fixing tools are required. 2. It is more in line with human health. 3. There will be no patina, water leakage and precipitation of heavy metal substances. 4. The required cost is low. 5. Only need to simply replace the rubber bushing, it can be applied to the pipe faucet of any caliber size. 6. Simple structure.

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Please refer to Figures 8 and 9. A tubular faucet adapter is mainly composed of an upper cover 12, several rubber bushes 13, a hard gasket 14, and an adapter body 11; As shown in Figure 8, assemble them in order. When using (as shown in Figure 10), first install the rubber bushing 13 and the hard washer 14 into the upper cover 12 in sequence, and then slightly align the adapter body 11 with the upper cover. After the 12 screws are screwed together (not completely locked at this time), put 4 sets of tubular faucets into the upper cover 12 and socket them together with the rubber bushing 13 (at this time, the caliber of the rubber bushing 13 is slightly smaller than that of the tubular faucet. 4), then hold the convex body 111 of the one-piece adapter body 11 with your hand and rotate it to make it screw upward. At this time, the front end 112 of the adapter body 11 will drive the hard washer 14 upward , and the hard washer 14 will drive the rubber bushing 13 upwards. Since the junction 141 between the hard washer 14 and the rubber bushing 13 and the junction 131 between the rubber bushing 13 and the upper cover 12 are all in the shape of an inclined plane, therefore, The adapter body 11 is screwed upwards and drives the hard washer 14 and the rubber bushing 13 in sequence. Since the joints 131, 141 are both inclined surfaces, the more the adapter body 11 is screwed upward, the joints 131, 141 The more the rubber bushing 13 is condensed inward, the tubular faucet 4 can be completely sealed. Furthermore, because the adapter body 11 is integrally formed, when the water flow 5 flows downward, there will be no leakage. Water leakage occurs; if the caliber of the tubular faucet 4 is relatively small, only a rubber bushing 13 of a smaller size needs to be replaced at this time, and then the above-mentioned method can be used to complete the smaller caliber of the tubular faucet 4 assembly and sealing.
