Description

Reducing pipe

A different diameter transfer tube, especially a different diameter transfer tube for strengthening the strength of the bridge structure and saving the production materials.

As shown in FIG. 1 , the water pipe joint 6 of the existing pipe diameter generally has a small sleeve portion 61 and a large socket portion 62 . The small socket portion 61 and the large socket portion 62 have a connecting portion 63 . The small sleeve portion 61 can be fitted with a first water pipe 2 having a first pipe diameter 21, and the large socket portion 62 can be fitted with a second water pipe 3 having a second pipe diameter 31. Moreover, the water pipe joint 6 usually connects the water pipe joint 6 and the water pipe by means of an auxiliary pipe joint 7, which is the same as the auxiliary water pipe 7 for the second water pipe 3 and the large socket portion 62 as shown in FIG. However, after the conventional water pipe joint 6 is assembled with the first water pipe 2 and the second water pipe 3, the connecting portion 63 may be in contact with the first water pipe 2 or the second water pipe 3 to cause the structure here. The strength is weak, and once the external force is hit, the connecting portion 63 will easily be broken or leaked. In addition, when the water pipe joint 6 is assembled and used, it is also required to specially manufacture the auxiliary pipe 7 of a corresponding specification to provide the water pipe joint 6 to be used in combination with the second water pipe 3, which will result in an increase in the manufacturing cost of the manufacturer. It is necessary to manufacture a plurality of the water pipe joints 6 and the auxiliary joint pipes 7 for use therewith, and the structure is complicated. Moreover, since the conventional water pipe joint 6 needs to be used with the auxiliary pipe joint 7, when the length is less than the total length of the water pipe joint 6 and the auxiliary joint pipe 7, the water pipe joint 6 cannot be used. The problem of the auxiliary nozzle 7 being constructed.

The main purpose of this creation is to solve the problem that the conventional water pipe joint has poor structural strength, excessive material cost and limited construction length.

In order to achieve the above objective, the present invention provides a different diameter transfer tube, which bridges a first water pipe and a second water pipe, the first water pipe has a first pipe diameter, and the second water pipe has a first pipe diameter A different second pipe diameter, the reducer pipe includes a base, a first bridge wall and a second bridge wall. Wherein, the base is formed with a through hole extending through both sides of the base. Furthermore, the first bridging wall is extended from one side of the base around the through hole, and the first bridging wall has a shape corresponding to the first pipe diameter so that the first bridging wall is tightly matched with the first water pipe. Bridge the inner diameter. Moreover, the second bridging wall is disposed on a side of the base on which the first bridging wall is formed and surrounds the first bridging wall, and the second bridging wall has a second bridging wall corresponding to the second diameter to make the second bridging The wall has a bridging outer diameter that closely matches the second water pipe.

In an embodiment of the present invention, the reducer has a gap formed between the first bridge wall and the second bridge wall.

Through the foregoing technical solutions, the present invention has at least the following advantages compared with the prior art: 1. The original bridge wall and the second bridging wall are disposed on the same side of the base, thereby eliminating the conventional structure. The connecting portion further improves the problem that the conventional structure is not strong and the pipe interference is easy. Second, the creation of the first bridging wall and the second bridging wall improves the conventional structure to be bridged by the auxiliary connecting tube, resulting in a complicated structure and high manufacturing cost. 3. The present invention separates the first bridging wall and the second bridging wall and forms a gap to reduce the materials required for the creation of the present invention. 4. The present invention makes the first bridging wall and the second bridging wall be disposed on the same side, and the connecting portion of the conventional structure is omitted, so that the different diameter connecting tube does not occupy too much piping distance after assembly.

The detailed description and technical content of this creation are as follows:

Referring to FIG. 2, as shown in the figure, the creation reducing pipe 1 can be made of a plastic material or mechanically processed from a metal material. The reducer tube 1 has a base 11 , a first bridge wall 12 and a second bridge wall 13 . Further, a hole 111 is formed in the center of the base 11 through the two sides of the base 11. Furthermore, the first bridging wall 12 surrounds the perforation 111 and is formed by one side of the base 11 . The first bridging wall 12 has a bridging inner diameter 121 . Moreover, the second bridging wall 13 is disposed on a side of the base 11 where the first bridging wall 12 is formed and surrounds the first bridging wall 12, and the second bridging wall 13 has a bridging outer diameter 131. Further, in an embodiment, the different diameter transfer tube 1 is produced by secondary injection molding, and the base 11 is formed of plastic during the first injection molding, and the base is to be After the seat 11 is cooled, a second injection molding is continued to form the first bridging wall 12 and the second bridging wall 13 on one side of the base 11. Furthermore, in an embodiment of the present invention, the different diameter adapter tube 1 forms a gap 14 between the first bridging wall 12 and the second bridging wall 13 during the design process, thereby manufacturing In the process of developing the different diameter transfer tube 1, the width of the gap 14 formed between the first bridging wall 12 and the second bridging wall 13 is adjusted, and the reducing tube 1 is controlled. The required materials can achieve the purpose of saving materials. In addition, the first bridging wall 12 has a first height 122, and the second bridging wall 13 has a second height 132. In an embodiment, the manufacturer may adjust the first according to implementation requirements. The height 122 is the same as the second height 132, or the first height 122 is different from the second height 132. Further, in the embodiment depicted in FIG. 2, the different diameter is transferred. The first height 122 of the first bridging wall 12 is smaller than the second height 132 of the second bridging wall 13 , so that the structural strength after the bridging can be ensured, and the manufacturing material can be saved. purpose. Further, in an embodiment, the creation further makes the diameter of the base 11 larger than the bridging outer diameter 131 of the second bridging wall 13 , and a limiting portion 15 is formed on the periphery of the base 11 , the limiting portion During the implementation of the present invention, the wall of the bridge pipe is placed against the wall of the bridge, and the assembly position of the reducer 1 is restricted.

On the other hand, when assembling the second water pipe 3, the user only has to insert the second water pipe 3 toward the second bridge wall 13 of the reducer pipe 1 and abut against the restriction portion 15, however The bridge outer diameter 131 of the second bridging wall 13 is matched with the second pipe diameter 31 by the diameter of the bridging outer diameter 131, so that the second bridging wall 13 is assembled with the second water pipe 3 It looks like a tight fit. In this way, the present invention can shorten the length of the bridge structure between the tube and the tube, thereby improving the pipeline interference problem caused by the conventional structure in the piping process.

In summary, the different diameter transfer tube is bridged to a first water pipe and a second water pipe. The first water pipe has a first pipe diameter, and the second water pipe has a first pipe diameter. The second diameter of the different diameter adapter tube includes a base, a first bridge wall and a second bridge wall. The base is formed with a through hole extending through the two sides of the base. The first bridge wall is formed by extending from the side of the base.
