Description

Technical Field

[0001] The present application relates to the technical field of pipe joints, and in particular to a freely rotatable PVC pipe joint. Background Art

[0002] A bridge generally refers to a structure built across rivers, lakes, and seas to enable vehicles, pedestrians, and others to pass smoothly. In order to prevent water accumulation from adversely affecting the structure and function of the bridge, the bridge needs to be installed with downpipes to guide and drain the accumulated water on the bridge. The downpipes are installed on the bridge through hoops, and two adjacent downpipes are connected by hot-melt fixed adapters.

[0003] However, in the process of implementing relevant technical solutions, it was found that at least the following technical problems exist: the requirements for the installation quality and aesthetic lines of bridge downpipes are becoming increasingly stringent. Currently, fixed adapters such as 45°, 90°, and 135° are mostly used in the market and construction production, which are only suitable for specific occasions. If other occasions are encountered, the fixed adapter angles may not match, resulting in the downpipe and the beam or pier not being close together, making the installation line of the downpipe not beautiful enough. Utility Model Content

[0004] The present application provides a freely rotatable PVC pipe joint, thereby solving the technical problem in the prior art that when installing a downpipe, if the angle of the fixed adapter does not match, the downpipe will not fit tightly against the beam or pier, making the installation line of the downpipe not beautiful enough. The application achieves the goal of making the downpipe fit tightly against the beam or pier of the bridge, making the installation line of the downpipe more beautiful to a certain extent.

[0005] The present application provides a freely rotatable PVC pipe joint, comprising a pipe joint, wherein two pipe joints are respectively connected to adjacent ends of two adjacent PVC downpipes; an aluminum-plastic alloy flexible pipe, which can be adjusted to an adaptive shape according to the shape of a bridge, and both ends of the aluminum-plastic alloy flexible pipe are fixedly connected to the two pipe joints; and a limiting component, which is used to limit the shape of the aluminum-plastic alloy flexible pipe.

[0006] Furthermore, the limiting assembly includes: a connecting plate, which is bendable and fixedly mounted on the bridge; a first connecting block, a plurality of which are spaced apart on the connecting plate; a second connecting block, a plurality of which are spaced apart on the aluminum-plastic alloy flexible tube; and a connecting piece, which is used to connect the first connecting block and the second connecting block together.

[0007] Furthermore, the connecting member includes: a connecting column, connecting holes are opened at corresponding positions of the first connecting block and the second connecting block, the connecting column is adapted to the size and shape of the connecting hole, and the connecting column is inserted into the connecting hole where the first connecting block and the second connecting block overlap; a limiting block, the limiting block is fixedly installed at one end of the connecting column; a limiting plate, a plurality of the limiting plates are located at the end of the connecting column away from the limiting block, and the plurality of limiting plates are arranged at equal intervals along the circumference of the connecting column, the limiting plate is arranged at the end of the outer peripheral surface of the connecting column away from the limiting block, and the angle formed between the side of the limiting plate close to the limiting block and the connecting column is an acute angle.

[0008] Furthermore, the distance between the second connecting block and the bridge is equal to the distance between the pipe joint and the bridge.

[0009] Furthermore, the end of the connecting column away from the limiting block is truncated cone-shaped.

[0010] The technical solution provided by this application has at least the following technical effects or advantages:

[0011] The use of aluminum-plastic alloy flexible pipes in conjunction with limiting components effectively solves the technical problem in the prior art that when installing downpipes, if the angles of the fixed adapters do not match, the downpipes and the beams or piers will not fit closely, making the installation line of the downpipes not beautiful. This allows the downpipes to fit closely with the beams or piers of the bridge, making the installation line of the downpipes more beautiful to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The embodiment of the present application discloses a freely rotatable PVC pipe joint 1, in which a pipe joint 1 is fixedly installed at both ends of an aluminum-plastic alloy flexible tube 2. The aluminum-plastic alloy flexible tube 2 can be adjusted to a suitable shape according to the shape of a bridge 4. At the same time, a limiting component 3 is provided to limit the shape of the aluminum-plastic alloy flexible tube 2, so that the downpipe is closely attached to the beam or pier of the bridge 4, making the installation line of the downpipe more beautiful to a certain extent.

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Reference Figure 1 , Figure 2 A freely rotatable PVC pipe joint 1 includes an aluminum-plastic alloy flexible pipe 2 that can be adjusted to a suitable shape according to the shape of a bridge 4, a limiting component 3 for limiting the shape of the aluminum-plastic alloy flexible pipe 2, and a pipe joint 1 is fixedly connected to each end of the aluminum-plastic alloy flexible pipe 2. The two pipe joints 1 are respectively hot-melt connected to the adjacent ends of two adjacent PVC downpipes 5. The aluminum-plastic alloy flexible pipe 2 cooperates with the limiting component 3 to make the downpipe fit closely with the beam or pier of the bridge 4, which makes the installation line of the downpipe more beautiful to a certain extent.

[0021] Reference Figure 1-Figure 4 The limiting component 3 includes a connecting plate 31 and a connecting piece 34. The connecting plate 31 is bendable so that the connecting plate 31 can adapt to different shapes of the bridge 4. A plurality of first connecting blocks 32 are arranged at intervals on the connecting plate 31, and a plurality of second connecting blocks 33 are arranged at intervals on the aluminum-plastic alloy flexible pipe 2. The connecting plate 31 is installed at a position on the bridge 4 where an adapter is required. At this time, the mounting plate is adapted to the shape of the corresponding position of the bridge 4, and then the two pipe joints 1 are respectively connected to the adjacent ends of the two adjacent PVC downpipes 5 by hot-melt connection, and then the shape of the aluminum-plastic alloy flexible pipe 2 is adjusted according to the shape of the bridge 4, and the second connecting block 33 is connected to the first connecting block 32 at a suitable position through the connecting piece 34 to limit the shape of the aluminum-plastic alloy flexible pipe 2. The distance of the second connecting block 33 away from the bridge 4 is equal to the distance of the pipe joint 1 from the bridge 4, so that the spacing between the aluminum-plastic alloy flexible pipe 2 and the bridge 4 is roughly equal to the spacing between the PVC downpipe 5 and the bridge 4, which makes the installation line of the downpipe more beautiful to a certain extent.

[0022] Reference Figure 2-Figure 5The connecting member 34 includes a connecting column 341, a limiting block 342, and a plurality of limiting pieces 343. The first connecting block 32 and the second connecting block 33 have connecting holes 321 at corresponding positions. The connecting column 341 is adapted in size and shape to the connecting hole 321. The limiting block 342 is fixedly mounted at one end of the connecting column 341. The plurality of limiting pieces 343 are located at the end of the connecting column 341 away from the limiting block 342. The plurality of limiting pieces 343 are arranged at equal intervals along the circumference of the connecting column 341. The limiting pieces 343 are arranged at the end of the outer peripheral surface of the connecting column 341 away from the limiting block 342. The limiting pieces 343 are close to the limiting pieces 343. The angle formed between the side of the positioning block 342 and the connecting column 341 is an acute angle, so that when the second connecting block 33 is connected to the first connecting block 32 at a suitable position, the two connecting holes 321 on the first connecting block 32 and the second connecting block 33 overlap, and the end close to the limiting plate 343 is inserted toward the connecting hole 321 until the first connecting block 32 and the second connecting block 33 are located between the limiting plate 343 and the limiting block 342, and the first connecting block 32 and the second connecting block 33 are connected together. The end of the connecting column 341 away from the limiting block 342 is truncated cone-shaped, which is convenient for insertion into the connecting hole 321.

[0023] The working principle of the embodiment of the present application is: when installing the downpipe on the bridge 4, the PVC downpipe 5 is installed on the bridge 4, and the connecting plate 31 is installed at the corresponding position on the bridge 4 at the position where the pipe joint 1 is needed. At this time, the shape of the installation plate is adapted to the shape of the corresponding position of the bridge 4, and then the two pipe joints 1 are respectively connected to the adjacent ends of the two adjacent PVC downpipes 5 by hot-melt connection, and then the shape of the aluminum-plastic alloy flexible tube 2 is adjusted according to the shape of the bridge 4, and the second connecting block 33 is connected to the first connecting block 32 at a suitable position through a connecting piece 34, and the shape of the aluminum-plastic alloy flexible tube 2 is restricted, so that the downpipe is closely attached to the beam or pier of the bridge 4, which makes the installation line of the downpipe more beautiful to a certain extent.
