[0032] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0033] Reference Figures 1 to 6 , is an embodiment of the present utility model, and proposes a split-type cement self-cutting joint, including a first main body 1, the first main body 1 having a first threaded portion 101 and a second threaded portion 102, the thread directions of the first threaded portion 101 and the second threaded portion 102 are opposite, the first threaded portion 101 and the second threaded portion 102 are respectively located at both ends of the first main body 1, the second main body 2 having a first threaded hole 201 and a second threaded hole 202, and the second threaded portion 102 is threadedly arranged in the first threaded hole 201.

[0034] In this embodiment, this split-type self-cutting cement joint consists of a first body 1 made of high-strength material and a second body 2 made of conventional material. First, the second body 2 is connected to the first body 1 as a single unit, and then the first body 1 is secured to the roof. Made of high-strength material, it can withstand significant tension and compression when secured to the roof, ensuring a stable and secure connection. High-strength materials, such as steel and alloys, offer high strength and durability. The first and second threaded portions 101 and 102 on the first body 1 continue to function as connectors. The first threaded portion 101 is used for subsequent connection to the roof or equipment, while the second threaded portion 102 is used for connection to the second body 2. Conventional materials are used to reduce costs. Conventional materials, such as plastic and cast iron, are relatively low-cost while still meeting general connection and usage requirements. The first and second threaded holes 201 and 202 on the second body 2 are used for connection to the first body 1 and for mounting other components, respectively. By using conventional materials for the second body 2, costs can be reduced without compromising overall performance. This design strategy can significantly reduce the total cost of a project in large-scale applications. The first body 1 is constructed of high-strength materials, ensuring the performance and reliability of key components. The second body 2 is first connected to the first body 1 as a single unit before being secured to the roof, making the installation process more convenient and streamlined. The main body connections can be made on the ground or in other convenient locations before the entire installation and securement process. During maintenance and component replacement, the first and second bodies 1 and 2 can be accessed separately as needed, improving maintenance efficiency. The split design of the first and second bodies 1 and 2, along with the choice of different materials, provides greater flexibility for connecting different types of pipes and components. The appropriate connection method and material combination can be selected based on specific usage requirements and environmental conditions. While ensuring connection performance, this reduces material costs and improves product cost-effectiveness. This cost advantage is particularly significant for large-scale construction projects or piping systems. The overall connection and installation process is simple and straightforward, requiring no complex tools or techniques. This improves construction efficiency and shortens project schedules. The high-strength first body 1 ensures a secure and reliable fixation to the roof, while the conventional second body 2 also meets common connection requirements. The entire second body 2 offers high stability and reliability during use. Different material combinations and connection methods can be selected to suit different application scenarios and requirements. It is suitable for various building structures and piping systems and has strong adaptability.

[0035] Furthermore, the first body 1 has a boss portion 103 , and the boss portion 103 is located between the first threaded portion 101 and the second threaded portion 102 .

[0036] In this embodiment, the first body 1 has a boss portion 103 located between the first threaded portion 101 and the second threaded portion 102. The presence of the boss portion 103 enhances the structural strength of the first body 1. When the first threaded portion 101 is secured to the roof and the second threaded portion 102 is connected to the second body 2 and subjected to various external forces, the boss portion 103 provides support and reinforcement, preventing deformation or breakage at the connection point of the first body 1. This enhanced structural stability helps ensure the reliability and safety of the entire second body 2 system. The boss portion 103 serves as a reference point and operating point during installation. When securing the first body 1 to the roof, the operator can use the boss portion 103 to better control the position and orientation of the first body 1, making installation more accurate and convenient. Furthermore, when connecting the second body 2, the boss portion 103 helps determine the insertion depth of the second threaded portion 102 into the first threaded hole 201, ensuring a tight connection. The boss portion 103 also limits the connection position of the second body 2 on the first body 1. When the first threaded hole 201 of the second body 2 is connected to the second threaded portion 102 of the first body 1, the boss portion 103 can prevent the second body 2 from being over-screwed in or out, ensuring that the connection is in the correct position, thereby ensuring the performance and function of the second body 2. The design of the boss portion 103 increases the strength and stability of the first body 1, thereby improving the reliability of the entire second body 2. During long-term use, it can withstand the influence of various external forces and environmental factors, reducing the frequency of maintenance and replacement. This helps to reduce maintenance costs and improve the overall efficiency of the system. When maintenance and overhaul are required, the boss portion 103 can serve as an obvious sign to help operators quickly find the location of the second body 2 and disassemble and repair it. This makes maintenance work more efficient and convenient, reducing downtime and the impact on production or life.

[0037] Furthermore, the first threaded hole 201 and the second threaded hole 202 are communicated with each other.

[0038] In this embodiment, the first threaded hole 201 and the second threaded hole 202 are interconnected to form a through hole. Compared with the blind hole of the integrated structure in the prior art, the through hole has obvious advantages in processing. Blind hole processing usually requires more complex processes and tools, and is more difficult in terms of depth control. However, the through hole can be achieved through simpler processing methods such as drilling, which reduces the processing difficulty and cost. The processing process of the through hole is relatively more efficient, which can reduce the processing time and labor cost investment. The reduction in processing costs is one of the important advantages of the through hole design. Since the complex blind hole processing steps are reduced, the utilization rate of materials may also be improved, further reducing production costs. For large-scale production of split cement self-cutting joints, this cost reduction effect is more significant, which can improve the market competitiveness of the product.

[0039] Furthermore, the boss portion 103 has a first limiting protrusion 104, and the second main body 2 has a second limiting protrusion 203. The first limiting protrusion 104 and the second limiting protrusion 203 are both arranged in a plurality of circles. The first limiting protrusion 104 is configured to abut against the external environment, and the second limiting protrusion 203 is configured to abut against the boss portion 103.

[0040] In this embodiment, in the split cement self-cutting joint, the boss portion 103 has a first limiting protrusion 104, and the second body 2 has a second limiting protrusion 203, and both are arranged in a plurality of circles. The first limiting protrusion 104 is configured to abut against the external environment, and the second limiting protrusion 203 is configured to abut against the boss portion 103. The first limiting protrusion 104 and the second limiting protrusion 203 cooperate with each other to play a role in positioning and limiting. During the installation process, when the second body 2 is connected to the first body 1, the second limiting protrusion 203 abuts against the boss portion 103, which can accurately determine the position of the second body 2 on the first body 1 and ensure the accuracy and stability of the connection. At the same time, the first limiting protrusion 104 abuts against the external environment, which can limit the movement of the first body 1 after installation and prevent the second body 2 from loosening or displacement due to external force. The circumferentially arranged limiting protrusions increase the contact area and improve the stability of the connection.

[0041] Furthermore, the first limiting protrusion 104 and the second limiting protrusion 203 respectively have a first inclined surface 105 and a second inclined surface 204 , and the first inclined surface 105 and the second inclined surface 204 face opposite directions.

[0042] In this embodiment, the first beveled portion 105 of the first retaining protrusion 104 and the second beveled portion 204 of the second retaining protrusion 203 face opposite directions. This design aligns with the opposite thread directions of the first threaded portion 101 and the second threaded portion 102 of the first body 1. During installation, since the first and second threaded portions 101, 102 have opposite thread directions, rotating the first body 1 for connection generates forces in different directions. The design of the retaining protrusions with opposite bevels counteracts these forces, ensuring a more stable connection between the second body 2 and the first body 1. When the first threaded portion 101 is rotated clockwise for fastening, the generated force tends to cause the second body 2 to move in one direction. The beveled surface of the first retaining protrusion 104 interacts with this force, providing a certain resistance and preventing excessive movement of the second body 2. Simultaneously, the opposite beveled surface of the second retaining protrusion 203 also mates tightly with the boss portion 103, ensuring a stable connection. The design of the opposite bevels, combined with the opposite thread directions, creates a more secure connection. During the operation of the pipeline system, when subjected to various external forces, this structure can better disperse the stress and improve the reliability of the connection.

[0043] Furthermore, a screw member 3 is included. The screw member 3 is threadedly disposed in the second threaded hole 202 , and a transverse reinforcement member 4 is disposed on the screw member 3 .

[0044] In this embodiment, the screw member 3 is threadedly disposed within the second threaded hole 202, and the transverse reinforcement 4 is disposed on the screw member 3. The screw member 3 is threadedly connected to the second threaded hole 202, providing a more secure connection to other components. Compared to connections relying solely on the threaded hole itself, the addition of the screw member 3 increases the strength and stability of the connection. Especially under conditions of high tension or pressure, the screw member 3 can effectively prevent the connection from loosening or slipping. The transverse reinforcement 4 disposed on the screw member 3 further enhances the overall stability of the second body 2. The transverse reinforcement 4 can resist external forces from various directions, reducing deformation and displacement of the second body 2 during use. The combination of the screw member 3 and transverse reinforcement 4 can be adjusted and optimized according to specific installation requirements. Screw members 3 of different lengths, diameters, and materials, as well as transverse reinforcements 4 of different shapes and strengths, can be selected to meet different load requirements. The stable connection and reinforcement structure help improve the installation quality of the second body 2. This reduces leakage, looseness, and other problems caused by a weak connection, ensuring the normal operation of the pipeline system.

[0045] Furthermore, the transverse reinforcement 4 has an abutment portion 401 configured to abut against a structure perpendicular to the ground.

[0046] In this embodiment, the transverse reinforcement 4 has an abutment portion 401 configured to abut against a structure perpendicular to the ground. When the abutment portion 401 of the transverse reinforcement 4 abuts against a structure perpendicular to the ground, it provides additional support for the second body 2, enhancing the stability of the entire second body 2. This support effectively resists pressure from the fluid within the pipeline, external vibrations, and other external forces, reducing sway and displacement of the second body 2. The contact between the abutment portion 401 and the vertical structure distributes some of the stress onto the vertical structure, alleviating the pressure on the second body 2 itself. This reduces the risk of damage to the second body 2 due to stress concentration and extends its service life. The stable support and stress distribution ensure the quality of the installation of the second body 2. The abutment portion 401 of the transverse reinforcement 4 can adapt to various vertical structures, such as walls and pillars. This allows the second body 2 to find a suitable support point in a variety of installation environments, enhancing the product's adaptability and versatility. If maintenance or repair of the pipeline system is required, the abutment portion 401 can serve as a fixed point, facilitating operator access. At the same time, the presence of the abutting portion 401 also makes it easier to identify and locate the second body 2, facilitating inspection and maintenance.

[0047] Furthermore, it also includes a hanging member 402, which is arranged on the screw member and / or the transverse reinforcement member 4, and has a hanging portion.

[0048] In this embodiment, the hanging portion of hanger 402 can be used to suspend various items or equipment. In certain specific applications, such as installing piping systems inside buildings, hanger 402 can be used to suspend pipes, lamps, ventilation equipment, and the like, saving space and improving installation convenience. This hanging function reduces reliance on the ground or other supporting structures, making installation more flexible and diverse. The provision of hanger 402 provides a new installation method for split cement self-cutting joints. In addition to traditional fastening to vertical structures such as walls and ceilings, hanger 402 can now be used for suspended installation. This allows the joint to adapt to a wider range of installation environments and requirements, improving the product's versatility and applicability. Because hanger 402 can be moved and adjusted within a certain range, the position and height of the suspended items can be easily adjusted according to actual needs. This is particularly convenient for equipment that requires frequent repositioning or maintenance. The adjustability of hanger 402 also enhances the installation process, allowing for fine-tuning after installation to ensure accurate and stable installation. When properly installed and bearing a certain amount of weight, hanger 402 provides additional stability to the joint. The connection between the hanger 402 and the screw member and / or the transverse reinforcement 4 can disperse part of the weight and stress, reduce the pressure on the joint itself, and thus improve the stability of the entire system. The hanging installation can make full use of the vertical space of the building and reduce the occupation of ground space. This is very beneficial for places with limited space, such as small offices, shops, warehouses, etc., and can improve the utilization rate of space. At the same time, the hanging installation can also make the pipeline system and equipment more neat and beautiful, and reduce the sense of clutter. The addition of the hanger 402 adds an important functional feature to the split cement self-cutting joint, making it not only a connector, but also can be used as a hanging device. The design of the hanger 402 enables the joint to adapt to a variety of different application scenarios, such as industrial plants, commercial buildings, home decoration, etc. Whether it is hanging pipes, lamps, ventilation equipment or other items, you can choose the appropriate hanger 402 for installation according to actual needs.

[0049] Furthermore, the abutting portions 401 are arranged in a plurality of circles.

[0050] In this embodiment, multiple circumferentially arranged abutment portions 401 can abut against the vertical structure from different directions, providing more uniform and stable support. Compared to a single abutment portion 401, this design can better resist external forces from all directions and reduce joint shaking and displacement. Especially when the pipeline system is subjected to high pressure or complex external forces, the circumferentially arranged abutment portions 401 can ensure a more secure and reliable connection between the joint and the vertical structure. When external forces act on the joint, the circumferentially arranged abutment portions 401 can disperse the stress to multiple locations, preventing stress concentration at a single point. This reduces the risk of damage to the joint and the vertical structure due to excessive localized stress and extends the service life of the joint. Because the abutment portions 401 are circumferentially arranged, different abutment positions can be selected during installation according to actual needs, adapting to different installation angles. This allows the joint to find the appropriate support point in a variety of complex installation environments, improving installation flexibility and versatility. Whether installed horizontally, vertically, or at an angle, the circumferentially arranged abutment portions 401 provide stable support for the joint. The presence of multiple abutment portions 401 can help installers more accurately determine the position and direction of the connector. During installation, the contact position of the abutment portion 401 with the vertical structure can be adjusted to make the connection between the connector and the piping system more accurate and reduce installation errors.
