DETAILED DESCRIPTION

[0025] The present application will now be described in further detail with reference to the accompanying drawings.

[0026] Drainage pipeline is a pipeline system for draining sewage, waste water and rainwater in buildings or areas, which includes indoor drainage pipeline and outdoor drainage pipeline. The indoor drainage pipeline mainly collects sewage from kitchens, toilets, bathrooms and other places and transports it to the building's main drain. The outdoor drainage pipeline is responsible for transporting sewage from the building to the municipal sewage pipeline network or sewage treatment facilities. The rainwater drainage pipeline collects and discharges rainwater into nearby rivers, lakes or rainwater collection systems. The materials of drainage pipeline are various, and the common ones are cast iron pipe, PVC pipe (polyvinyl chloride pipe), HDPE pipe (high density polyethylene pipe) and the like.

[0027] In a humid environment, there is a large amount of water vapor in the air. If the ratchet and clamping plate in the drainage pipeline are made of metal (such as iron), iron will react chemically with oxygen and water vapor in the air. When there are corrosive substances such as acidic or alkaline waste water, the corrosion process of metal will be accelerated.

[0028] The installation of the drainage pipe, the drainage pipe is mainly divided into open installation and concealed installation, the concealed installation is to install the drainage pipe in the structure inside of the wall, the ground, the ceiling and the like of the building, so that the pipe is hidden, the utility model is more suitable for concealed installation, in the construction stage of the building, the hole needs to be reserved according to the design position and the pipe diameter of the drainage pipe. The hole size is generally 50-100mm larger than the outer diameter of the pipe. For the pipe penetrating the floor, the sleeve pipe needs to be installed, the sleeve pipe is generally 20-50mm higher than the ground, and the inner diameter of the sleeve pipe is 1-2 larger than the outer diameter of the pipe. The sleeve pipe is used for preventing the pipe from being damaged due to the settlement of the building or the temperature change and the like in the use process, and facilitating the maintenance and replacement of the pipe.

[0029] Secondly, the pipe needs to be subjected to the corrosion prevention treatment (for the metal pipe) before being laid, and the slope and the direction of the pipe need to be paid attention to in the laying process, and the drainage needs to be ensured to be smooth, and the connection mode is similar to that of the open pipe.

[0030] Finally, after the pipe is installed, the pressure test and the water filling test need to be carried out before being hidden, the pressure test is mainly used for the pressure-bearing drainage pipe, and the pressure resistance of the pipe is checked, the water filling test is used for the non-pressure-bearing drainage pipe, and whether the pipe leaks or not is checked, only after the test is qualified, the hidden engineering construction can be carried out, and the position of the pipe needs to be marked after being hidden, so as to facilitate the later maintenance.

[0031] Please refer to Figs. 1-3 As shown in the figure, in the embodiment, a drainage pipe 2 connection structure is provided, which comprises: a connection main body 1, the left and right ends of the connection main body 1 are open and movably inserted with the drainage pipe 2, a protruding block 8 is arranged in the middle of the inside of the connection main body 1, a sealing ring 9 is connected to the left and right sides of the protruding block 8, a semicircular recess is arranged on the left and right sides of the connection main body 1, a fixed seat 4 is connected to the surface of the recess, a fixed ring 3 is connected to the recess through the fixed seat 4, a threaded sleeve 6 is connected to the left and right ends of the connection main body 1, and one end of the threaded sleeve 6 in the connection main body 1 is inclined.

[0032] The connecting body 1 is the core part of the entire drain pipe 2 connecting structure, which provides a basic framework for the installation and cooperation of other components. The open design at both ends of the connecting body 1 facilitates the insertion of the drain pipe 2, allowing different sections of the drain pipe 2 to be connected through it. The protrusion 8 in the middle of the connecting body 1 can serve two purposes: first, it can help the construction personnel accurately insert the drain pipe 2 into the appropriate position, ensuring the symmetry and stability of the entire connecting structure; second, the sealing ring 9 connected to the left and right sides of the protrusion 8 can better fit on the outer wall of the drain pipe 2, enhancing the sealing effect and preventing water leakage during the drainage process. The sealing ring 9 is connected to the left and right sides of the protrusion 8, and after the drain pipe 2 is inserted into the connecting body 1, the sealing ring 9 forms a tight sealing layer between the pipe outer wall and the connecting body 1 interior, filling the small gap between them with its own elasticity, effectively blocking water from leaking out of the connection, ensuring the sealing of the drainage system. The fixing seat 4 is connected to the surface of the groove, which serves as a connecting link between the fixing ring 3 and the connecting body 1. Through the fixing seat 4, the fixing ring 3 can be stably installed in the corresponding position, ensuring that the fixing ring 3 can exert appropriate fixing force on the drain pipe 2, ensuring the firmness of the entire connecting structure. The fixing ring 3 is installed in the groove through the fixing seat 4, which tightly grips the drain pipe 2 to prevent it from loosening in the connecting body 1. The threaded sleeve 6 can enhance the stability of the drain pipe 2 in the connecting body 1. By rotating the threaded sleeve 6, its inclined end gradually comes into contact with the surface of the drain pipe 2, increasing the stability of the drain pipe 2 and the connecting body 1, and preventing the drain pipe 2 from moving outward from the opening of the connecting body 1.

[0033] In this embodiment, the connecting body 1 is provided with a threaded groove at both ends of the opening, and a slope is provided inside the connecting body 1 on the side of the threaded groove. The slope corresponds to the inclined end of the threaded sleeve 6. The surface of the threaded sleeve 6 is threadedly connected to the connecting body 1. The inclined end of the threaded sleeve 6 is made of rubber. The threaded sleeve 6 is provided with a through hole with the same diameter as the internal diameter of the connecting body 1.

[0034] Through the threaded cooperation, the threaded sleeve 6 can be firmly installed at the opening part of the connecting body 1, and the installation and disassembly operations are facilitated. In actual use, when the connecting structure needs to be maintained, the threaded sleeve 6 needs to be replaced, or the drainage pipe 2 system needs to be adjusted, the corresponding operations can be easily completed by utilizing the threaded connection characteristics. When the drainage pipe 2 is installed, the drainage pipe 2 is first inserted into the connecting body 1 along the threaded sleeve 6 through hole, and the drainage pipe 2 is abutted against the sealing ring 9 at the protrusion 8, then the threaded sleeve 6 is rotated, and the inclined one end of the threaded sleeve 6 gradually moves along the slope inside the connecting body 1. Since the inclined one end of the threaded sleeve 6 is made of rubber material, the good elasticity and plasticity of the rubber can better fill the possible small gaps, prevent water leakage, and at the same time can increase the stability of the drainage pipe 2, prevent the drainage pipe 2 from moving to the outside of the opening of the connecting body 1.

[0035] The longitudinal section of the fixed ring 3 is in a semicircular arc shape, and corresponds to the semicircular arc-shaped groove provided in the connecting body 1. The front and rear ends of the fixed ring 3 are provided with extension blocks corresponding to the fixed seat 4, and the extension blocks and the surface of the fixed seat 4 are provided with threaded holes, and the threaded holes are threadedly connected with bolts 5, and the bottom end of the fixed ring 3 is connected with a metal spring.

[0036] The corresponding design of the fixed ring 3 and the semicircular arc-shaped groove shape makes the fixed ring 3 fit on the outer wall of the drainage pipe 2 at the groove, tightly wrapping and fixing the drainage pipe 2. The semicircular arc-shaped design not only conforms to the outer contour shape of the drainage pipe 2, but also matches the groove structure of the connecting body 1, ensuring that the fixed ring 3 can be stably positioned in the correct position after installation. The fixed ring 3 is firmly installed on the fixed seat 4 by threadedly connecting the bolts 5 in the threaded holes, and then it is fixed at the groove of the connecting body 1. In actual use, when the drainage pipes 2 of different diameters or due to manufacturing tolerances, the pipe diameters have certain slight differences, the metal spring can be self-adaptively adjusted according to the actual size of the drainage pipe 2, ensuring that the fixed ring 3 can still tightly fit on the outer wall of the drainage pipe 2, achieving good fixing effect. At the same time, when the drainage pipe is impacted by water flow, vibration and other external forces, the metal spring can play a buffering role, absorbing part of the impact force, reducing the influence of external force on the connection between the fixed ring 3 and the fixed seat 4, further maintaining the stability of the entire connecting structure, and prolonging the service life of the connecting structure.

[0037] Working principle:

[0038] In the installation of the drain pipe 2, first of all, the through hole opened by the threaded sleeve 6 is used as a guide entrance, the drain pipe 2 is inserted into the connecting body 1 along the through hole, and as the drain pipe 2 continuously penetrates, it stops at the sealing ring 9 at the protruding block 8, the protruding block 8 helps the construction personnel to accurately control the depth of the drain pipe 2 inserted, ensures that it is in the appropriate position in the connecting body 1, so that the entire connecting structure can maintain symmetry and stability, at the same time, the sealing ring 9 preliminarily forms a sealing state by virtue of the adhesion of the sealing ring 9 to the outer wall of the drain pipe 2 and the inside of the connecting body 1, fills the small gap between the two by virtue of the elasticity thereof, and prevents water leakage;

[0039] Then rotate the threaded sleeve 6, based on the threaded cooperation relationship between the surface of the threaded sleeve 6 and the threaded groove at the opening of the connecting body 1, the threaded sleeve 6 starts to rotate along the threaded groove and gradually moves to the inside of the connecting body 1, because the inclined end of the threaded sleeve 6 is made of rubber material and has good elasticity and plasticity, when it gradually stops at the surface of the drain pipe 2, on the one hand, it can better fill the small gap that may exist between the drain pipe 2 and the connecting body 1, further strengthen the sealing effect, effectively block the water flow from leaking out of the connection, further guarantee the sealing of the drainage system, on the other hand, by exerting a certain radial pressure on the drain pipe 2, the friction between the drain pipe 2 and the connecting body 1 is increased, thereby enhancing the stability of the drain pipe 2 in the connecting body 1, preventing the drain pipe 2 from moving to the outside of the opening of the connecting body 1, and ensuring that the drain pipe 2 can be stably positioned at the connection position;

[0040] Finally, rotate the bolt 5 to drive the fixing ring 3 to move downward, so that the metal spring plate 7 at the bottom end of the fixing ring 3 abuts against the surface of the drain pipe 2 to fix the drain pipe 2.
