Description

Technical Field

[0001] The utility model relates to the technical field of water pipe fittings, in particular to a same-direction splicing type manifold and a thread processing lathe. Background Art

[0002] The manifold includes two types: the manifold and the collector. It is a key structure in the water system. The manifold is a water distribution device used to connect the water supply of each heating pipe, and the collector is a water collection device used to connect the return water of each heating pipe. The two have similar structures and only different uses. The following explanation takes the manifold as an example.

[0003] Currently, water manifolds are mostly made of metals like plastic or stainless steel and molded using a mold. Different molds are required for different routes, resulting in numerous mold pairs and inconvenience in production scheduling. Due to the numerous processing steps involved, spliced ​​designs face the challenges of connection and sealing, leading to a complex structure and numerous leak points, increasing the risk of leakage.

[0004] For example, existing spliced ​​water distributors include the following forms:

[0005] 1) The main body of the water divider is made of plastic. Many supporting ribs extend around the main body. There are holes on the supporting ribs. If the main bodies of multiple water dividers are put together, the holes on the supporting ribs around them are all in a straight line. They can be strung together with metal rods. The metal rods are riveted on both sides with metal pads to achieve a stable connection of the spliced ​​water dividers.

[0006] Although this structure is strong, it cannot be disassembled, the number of routes cannot be increased or decreased, and its actual use is limited. In addition, this structure also has high requirements for the processing of metal rods. If the metal rods are bent and deformed, it will seriously affect the splicing efficiency and splicing results of the water divider, and even the splicing cannot be normal. Even if installed, the metal rods will generate external force on the plastic body, reducing the strength and life of the water divider. Furthermore, in order to achieve the connection of multiple water dividers, additional structures such as reinforcing ribs for the installation of metal rods are required, resulting in the size of the water divider being much larger than the main diameter of the water divider, occupying the usable space, and the shape is complex, the mold structure is difficult, and the injection molding requirements are high.

[0007] 2) There are also plastic manifolds that are spliced ​​and fixed with locking blocks. There are protrusions at both ends of its main body. After the two main body end faces are fitted together, the two adjacent parts are fixed with locking blocks. This structure mainly relies on the interference fit between the locking block and the main body parts to achieve fastening. The contact surface is large, so assembly and disassembly are difficult. In addition, there are support parts inside the connection parts. When splicing, the two connecting bodies, support parts, and locking parts need to be assembled together. There are many parts, the assembly process is complicated, and the efficiency is low. Furthermore, if the dimensions of the two connected main body end faces of the plastic manifold fastened by the locking block are not completely consistent, the connected parts will be misaligned or uneven when spliced, affecting the appearance of the product. Therefore, this structure has very high requirements for the processing accuracy of the main parts.

[0008] In view of this, the present utility model is proposed. Utility Model Content

[0040] First embodiment

[0041] Please refer to Figure 1 This embodiment provides a same-direction splicing type manifold. The manifold is divided into two types: manifold 100 and manifold. It is a key structure in the water system. The manifold 100 is a water distribution device used to connect the water supply of each heating pipe, and the manifold is a water collection device used to connect the return water of each heating pipe. The two have similar structures and only different uses. The following description will take the manifold 100 as an example.

[0042] The water distributor 100 includes a main body 110 and multiple branch pipes 120. Each branch pipe 120 is connected to the main body 110. The main body 110 is configured to be connected to a water supply pipe. Hot water enters the main body 110 of the water distributor 100 through the water supply pipe, then flows into the multiple branch pipes 120 for radiant heating, and finally flows back to the main body 110 of the manifold and is then returned for heating through the return pipe.

[0043] During the construction of the floor heating system, due to the different areas of different construction areas, different numbers of branch pipes 120 need to be configured. If a water distributor 100 with all numbers of branch pipes 120 is produced, multiple molds need to be prepared, which results in high production costs. The use of a spliced ​​water distributor 100 can reduce the number of molds, and during the construction process, different numbers of water distributors 100 can be selected for splicing according to the construction area, so it is widely used.

[0044] However, the existing spliced ​​water dividers 100 have at least one of the following defects: high processing cost, high processing precision requirements, large floor space, difficulty in reuse after disassembly, or the need to use additional connection tools. There is an urgent need to provide a new type of water divider 100 to solve any of the above problems. Therefore, the inventors propose the following solution.

[0045] Please refer to Figure 2 , one end of the main body 110 of the water divider 100 is provided with an internal thread 111, and the other end is provided with an external thread 112. The internal thread 111 and the external thread 112 are threadedly connected, so the rotation direction of the internal thread 111 and the external thread 112 are the same, and the pitch is the same. In addition, it is also necessary to control the thread starting point position of the internal thread 111 and the external thread 112 to be the same. Therefore, when multiple water dividers 100 need to be assembled and spliced, the connection of the water dividers 100 can be directly achieved through the cooperation of the internal thread 111 and the external thread 112. Since the thread starting point position of the internal thread 111 and the external thread 112 is the same, after the multiple water dividers 100 are threadedly connected, they can be spliced ​​in the same direction, ensuring that the branch pipes 120 of the multiple water dividers 100 after splicing are in the same direction on the same plane, so as to achieve reliable installation of the multi-way water divider 100.

[0046] Since the structure provided in this embodiment is directly connected via threads, unidirectional installation can be achieved by simply controlling the position of the thread starting point. Therefore, installation is convenient and quick, no additional connection structure is required, and space is reduced. Multiple water dividers 100 can be manufactured using only one set of molds, and then connected and assembled according to the required number of paths, making the splicing process more flexible. If disassembly is required, it can be achieved directly by twisting the threads, which facilitates disassembly and assembly, facilitates maintenance, and also improves installation efficiency.

[0047] In addition, compared with directly producing water distributors 100 of different numbers without splicing, the number of molds is significantly reduced, and only molds of water distributors 100 of common numbers can be configured, such as molds of 2-way, 3-way or 4-way water distributors 100. When splicing is required, the number of water distributors 100 that need to be spliced ​​can be determined according to the construction area. For example, if the floor heating system requires 10 branch pipes 120, two 2-way water distributors 100 and two 3-way water distributors 100 can be used to form a threaded connection.

[0048] In this embodiment, the thread starting points of the internal thread 111 and the external thread 112 being at the same position means that the thread starting points on the same mounting surface and the same thread diameter are at the same position.

[0049] For example, when the thread starting point of the internal thread 111 is confirmed based on the thread major diameter, the thread starting point of the external thread 112 should also be confirmed based on the thread major diameter; when the thread starting point of the internal thread 111 is confirmed based on the thread minor diameter, the thread starting point of the external thread 112 should also be confirmed based on the thread minor diameter.

[0050] For example, when the thread starting point of the internal thread 111 is confirmed by the surface on the side of the internal thread 111 close to the external thread 112 of the same water divider 100, the thread starting point of the external thread 112 is confirmed by the surface on the side of the external thread 112 away from the internal thread 111 of the same water divider 100.

[0051] Please refer to Figure 3 and Figure 4 In this embodiment, the starting point of the external thread 112 is Figure 3 The thread starting point of the internal thread 111 is at position a on the A surface. Figure 4 The position b where the thread minor diameter is located on the B surface in the figure ensures that multiple water distributors 100 can be threadedly connected in the same direction.

[0052] In this embodiment, during the processing of the external thread 112, the distance of the tool template is an integer multiple of the pitch of the external thread 112; during the processing of the internal thread 111, the distance of the tool template is an integer multiple of the pitch of the internal thread 111 ±0.5 times the pitch, so as to ensure that the internal thread 111 and the external thread 112 can be threadedly connected.

[0053] Please refer to Figure 3 、 Figure 4 and Figure 5In this embodiment, a first sealing groove 113 is provided on the side of the main body 110 having an external thread 112, and a second sealing groove 114 is provided on the side having an internal thread 111. When the internal thread 111 and the external thread 112 are threadedly connected, a sealing ring 200 is accommodated between the first sealing groove 113 and the second sealing groove 114 to prevent water leakage after multiple water distributors 100 are connected.

[0054] Since the thread starting points of the thread matching process of the same-direction spliced ​​manifold provided in this embodiment are the same, after multiple manifolds 100 are connected, the internal thread 111 and the external thread 112 are tightly matched without any leakage points. The provision of a sealing ring 200 can further prevent leakage.

[0055] In this embodiment, the first sealing groove 113 is located at an end of the external thread 112 close to the internal thread 111 , and the second sealing groove 114 is located at an end of the internal thread 111 away from the external thread 112 .

[0056] In the embodiment of the present invention, unless otherwise specified, directional words such as “close to” or “far away from” are all based on the main body 110 of the same water separator 100 .

[0057] In this embodiment, a rounded corner 115 is provided on the end surface of the second sealing groove 114 away from the internal thread 111 to prevent the surface of the water divider 100 from being scratched and to facilitate the installation of the two water dividers 100 .

[0058] In this embodiment, the number of the branch pipes 120 is 4. In other implementations, the number of the branch pipes 120 may be 2, 3, or 5.

[0059] The present embodiment provides a same-direction splicing type manifold, and its assembly process is as follows: the internal thread 111 of one manifold 100 is threadably connected with the external thread 112 of another manifold 100, and the internal threads 111 and external threads 112 of multiple manifolds 100 are connected in the above manner to realize the splicing of manifolds 100 of different numbers.

[0060] Second embodiment

[0061] Please refer to Figure 6 and Figure 7 This embodiment provides a thread processing lathe 300, which is suitable for processing the internal thread 111 and the external thread 112 on the same-direction spliced ​​manifold of the first embodiment, including: a spindle box 310, a dust collection mechanism 320, a tool holder 330 and a positioning mechanism 340.

[0062] One end of the spindle box 310 is connected to the dust collection mechanism 320. The spindle box 310 accommodates a spindle 311. The product fixing end of the spindle 311 extends out of the spindle box 310 and its orthographic projection is located in the dust collection mechanism 320. The product fixing end of the spindle 311 is used to fix and install the product. For example, in this embodiment, the product fixing end of the spindle 311 is used to install the water divider 100 provided in the first embodiment, so as to form an internal thread 111 and an external thread 112 at both ends of the water divider 100, respectively.

[0063] The tool holder 330 is spaced apart from the main shaft 311 , and the tool holder 330 can selectively move toward the main shaft 311 to perform thread processing on the product mounted on the main shaft 311 .

[0064] The positioning mechanism 340 is located above the main shaft 311 . A positioning member 312 is provided on the surface of the main shaft 311 . The positioning mechanism 340 cooperates with the positioning member 312 for positioning.

[0065] In this embodiment, the positioning member 312 is an annular positioning block 342, which is sleeved on the surface of the main shaft 311, and a positioning groove 313 is provided on the annular positioning block 342; the positioning mechanism 340 includes a bracket 341 and a positioning block 342, the positioning block 342 is installed with the bracket 341, and the positioning block 342 can be selectively moved relative to the bracket 341 to engage in the positioning groove 313 and cooperate with the annular positioning block 342 for positioning.

[0066] Specifically, the positioning groove 313 is a V-shaped groove, and the positioning block 342 is a V-shaped block, so as to achieve rapid positioning of the thread starting point of the water divider 100, and the positioning process is fast and accurate.

[0067] The working principle of a thread processing lathe 300 provided in this embodiment is as follows:

[0068] The molded water divider 100 is installed on the main shaft 311, and the main shaft 311 is positioned using a V-shaped groove and a V-shaped block, so as to position the water divider 100 on the main shaft 311. After the positioning is completed, the tool holder 330 is operated to approach the direction of the main shaft 311, and then the tool body on the tool holder 330 respectively turns the internal thread 111 and the external thread 112 at both ends of the main body 110 of the water divider 100 to complete the processing of the water divider 100.

[0069] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
