Description

Technical Field

[0001] The utility model relates to the field of water pipe joints, and particularly relates to a wall-mounted water pipe joint with a detachable installation structure. Background Technique

[0002] A joint is a component used to connect water pipes. Water pipe joints can be classified into: external thread end-connected water pipe joints, ferrule-type water pipe joints, and self-fixing water pipe joints according to their usage methods.

[0003] Some of the common water pipe joints on the market at present are used inside the wall, and the other part is used to connect to the wall outside. For example, the water pipe joints used in bathrooms usually need to connect hot and cold water inlet pipes and connect outlet devices such as faucets or shower heads. Therefore, the water pipe joints in this scenario are usually fixed on the wall. The common wall fixing method for such water pipe joints is to set a fan-shaped connecting seat at the rear of the water pipe joint, and the connecting seat can be fixed to the wall through screws, thereby connecting the entire water pipe joint to the wall.

[0004] As disclosed in the Chinese patent with the patent number ZL202322914758.3: "A three-way water pipe elbow includes a straight pipe and a bent pipe communicated with the straight pipe. The bent part of the bent pipe has a thickened bent wall, a vacuum sound insulation cavity is arranged in the thickened bent wall, and a buffer rubber pad is fixed on the arc-shaped wall inside the thickened bent wall. The utility model can play a good sound insulation and noise reduction role by setting a thickened bent wall at the bent pipe and arranging a vacuum sound insulation cavity in the thickened bent wall. In addition, a buffer rubber pad is arranged on the arc-shaped wall inside the thickened bent wall to play a role in buffering the impact of water flow, and can play a role in buffering and noise reduction."

[0005] Including the solutions described in the above patents, there is a problem with this type of water pipe joint that can be fixed on the wall in the prior art, that is, since the mounting plates of the existing water pipe structures are integrally formed at the rear of the joint body, this increases the production difficulty of the entire water pipe joint. And when the water pipe joint is packaged and transported, due to the presence of the mounting plate, it will also cause the space occupied by each water pipe joint to increase, thereby increasing the transportation cost. Summary of the Invention

[0006] In order to overcome the deficiencies of the high production difficulty and high transportation cost of the water pipe joints that can be fixed on the wall in the prior art, the utility model provides a wall-mounted water pipe joint with a detachable installation structure.

[0011] The connection structure includes a connection post protruding from the connection platform, a connection hole formed in the installation plate, and a fastening bolt passing through the connection hole. A threaded hole capable of forming a threaded fit with the fastening bolt is formed at the top of the connection post. The connection hole includes an insertion section and a bolt section. The diameter of the bolt section is larger than that of the insertion section, and an interference step is arranged between the insertion section and the bolt section. The connection post is inserted into the insertion section of the connection hole, the rod part of the fastening bolt passes through the bolt section and forms a threaded fit with the threaded hole, and the head of the fastening bolt is located in the bolt section of the connection hole and forms an interference fit with the interference step.

[0012] Furthermore, a limiting structure is further arranged between the connection platform and the installation plate; the limiting structure includes a plurality of limiting posts protruding from the installation plate and a plurality of limiting grooves recessed in the connection platform. The limiting posts face the connection platform and can form an insertion fit with the limiting grooves, and the limiting posts are symmetrically distributed on both sides of the connection hole.

[0013] Furthermore, the joint body includes a straight pipe and a U-shaped bent pipe; one end of the straight pipe is a closed end, and the other end is an open end, and the opening on the open end of the straight pipe is the water outlet interface; both ends of the "U" shape of the U-shaped bent pipe are open, and the bottom of the "U" shape of the U-shaped bent pipe is connected to the side wall of the bent pipe section, so that the straight pipe and the U-shaped bent pipe are in communication.

[0014] Furthermore, a fitting groove is further formed on one side of the installation plate close to the joint body. The rear side of the joint body is fitted into the fitting groove, and a sealing gasket is further arranged at the bottom of the fitting groove. The sealing gasket is clamped between the table surface of the connection platform and the bottom of the fitting groove.

[0015] Furthermore, a plurality of support ribs are protruding on the periphery of the fitting groove on the installation plate. The support ribs face the joint body, and the inner side of the support ribs is in contact with the outer side wall of the joint body.

[0016] Furthermore, a sealing plug is embedded and connected in the bolt section of the connection hole. The sealing plug is located outside the head of the fastening bolt and blocks the opening of the connection hole.

[0017] Furthermore, socket columns are provided at both ends of the U-shaped elbow near the water inlet interface. A plurality of sealing ribs are convexly provided on the surface of the socket column, and the sealing ribs can form an interference fit with the inner wall of the water pipe.

[0018] Furthermore, an internal thread is provided at the opening end of the straight pipe located inside the water outlet interface, and an external pipe fitting can be thread-fitted into the water outlet interface to realize connection with the joint body.

[0019] Furthermore, the connecting column is provided in a cylindrical or square column shape.

[0020] Installation method of the present utility model:

[0021] Before installing the joint body, the connection between the joint body and the mounting plate needs to be completed. First, the sealing gasket is fitted into the fitting groove of the mounting plate, and then the connecting platform at the rear of the joint body is aligned with the fitting groove of the mounting plate and inserted, so that the rear side of the joint body can be fitted into the fitting groove. At the same time, the limiting column convexly provided in the fitting groove is inserted and fitted into the limiting groove on the connecting platform, and the supporting ribs located on the periphery of the fitting groove also adhere to the outer wall of the joint body. Then, the fastening bolt is inserted into the connecting hole from the bolt section of the connecting hole and tightened. The rod portion of the shown fastening bolt can be thread-fitted into the threaded hole of the connecting column until the head of the fastening bolt forms an interference fit with the interference step in the connecting hole. At this time, the fastening bolt is completely tightened. Finally, the sealing plug is installed into the connecting hole to block the head of the fastening bolt. Thus, the connection between the joint body and the mounting plate is completed. Then, the mounting plate can be attached to the wall surface, and the entire mounting plate is fixed to the wall surface by screwing the screw through the mounting hole on the mounting plate. Thereby, the joint body is also fixed to the wall surface. When connecting an external water pipe or pipe fitting to the joint body subsequently, only need to heat the head of the external water pipe first and then socket it onto the socket column of the joint body. Then, when the external water pipe cools, its inner wall will shrink and form an interference sealing fit with the sealing ribs on the socket column, and the external pipe fitting can directly form a thread fit with the internal thread on the joint body and thus be tightened onto the joint body.

[0022] The beneficial effects of the present utility model are as follows:

Therefore, the joint body and the mounting plate can be separately processed and formed during the production process, effectively reducing the processing difficulty. Similarly, when packing, the two can also be separately packaged, thus saving the packaging space and reducing the transportation cost;

[0024] 2. A limiting structure is also provided between the joint body and the mounting plate. By relying on the limiting structure, not only can the connection strength between the joint body and the mounting plate be strengthened, but also the rotation of the joint body relative to the mounting plate after connection can be prevented, ensuring the stability of the water pipe joint during use.

[0025] 3. A sealing gasket is clamped between the joint body and the mounting plate, and a sealing plug is also embedded in the connection hole on the mounting plate for passing through the fastening bolt, so as to ensure that liquid cannot enter the gap between the joint body and the mounting plate and cannot enter the connection hole, effectively avoiding corrosion of each component and thus improving the service life of the water pipe joint.

[0026] 4. A number of support ribs are also protruded from the mounting plate towards the joint body. The support ribs can fit on the outer wall of the joint body. When the mounting plate is connected to the joint body and installed on the wall, the support ribs can support the joint body from below, further improving the integrity of the water pipe joint.
