Description

Technical Field

[0001] This utility model relates to the field of plastic pipe connection technology, specifically to an adjustable-angle plastic connection elbow. Background Technology

[0002] Plastic pipes are widely used in many fields. When using plastic pipes, multiple pipes need to be connected together. At the bends, elbows are used for connection. Existing elbows usually use electrofusion to connect with plastic pipes, which is a simple, long-lasting and stable connection method.

[0003] A search of existing technology revealed an "elbow for connecting plastic pipes," with publication number "CN221991221U." This device relies on a rotating wheel to drive a valve stem to rotate, thus connecting the fluid channel inside the ball to the pipeline and achieving flow passage. When it is necessary to close the flow passage, the rotating wheel drives the valve stem to rotate, causing the fluid channel inside the ball to turn to the side of the pipeline, thereby achieving circuit breaking and improving the functionality of the elbow. However, because the bending angle is difficult to match well with the pipeline when connecting some pipes, the connection part needs to be adjusted when connection operations are required, which affects the working efficiency of elbow connection.

[0004] Based on this, this utility model designs an adjustable-angle plastic connecting elbow to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adjustable angle plastic connecting elbow.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable-angle plastic connecting elbow includes two arc-shaped pipe ends, each with a connecting end fixedly connected to its end; an adjusting mechanism disposed between the two arc-shaped pipe ends, the surface of the adjusting mechanism extending into the interior of the adjacent arc-shaped pipe ends; wherein, the adjusting mechanism includes a sliding component installed between the two arc-shaped pipe ends, the surface of the sliding component extending into the interior of the arc-shaped pipe ends; and two locking components installed on the sliding component near the interior of the adjacent arc-shaped pipe ends, the surfaces of the locking components extending into the interior of the adjacent arc-shaped pipe ends.

[0008] Furthermore, the sliding assembly includes an arc-shaped inner tube disposed between the two arc-shaped tube heads. The transverse interface of the arc-shaped inner tube is arc-shaped, and both ends of the arc-shaped inner tube extend into the interior of the adjacent arc-shaped tube heads. The surface of the arc-shaped inner tube is slidably connected to the inner wall of the adjacent arc-shaped tube head. A sealing ring is provided at the end of the arc-shaped inner tube, and the sealing ring is fixedly connected to the end of the arc-shaped tube head near the connection end. The two arc-shaped tube heads slide on the surface of the arc-shaped inner tube to achieve the need for adjustment at different angles.

[0009] Furthermore, the locking assembly includes multiple connecting rods. One connecting rod is fixedly connected to the inner wall of the arc-shaped inner tube, and the other connecting rod is fixedly connected to the inner wall of the adjacent arc-shaped tube head. An inner ring positioning seat and a threaded sleeve are rotatably connected between the adjacent connecting rods. The inner ring positioning seat is located inside the arc-shaped inner tube, and the threaded sleeve is located inside the arc-shaped tube head. When the inner ring positioning seat moves closer to the threaded sleeve, the connecting rods cause the arc-shaped inner tube to slide along the inner wall of the arc-shaped tube head.

[0010] Furthermore, the surface of the arc-shaped inner tube is provided with multiple annular grooves, and a sealing ring is fixedly connected to the inner wall of each annular groove. The surface of one of the sealing rings contacts the inner wall of the adjacent arc-shaped tube head. The cooperation between the annular grooves and the sealing rings maintains a good sealing effect.

[0011] Furthermore, the inner wall of the threaded sleeve is threaded with a threaded rod, the two ends of which extend to the outside of the threaded sleeve. Rotation of the threaded rod will cause the threaded sleeve to move relative to the surface of the threaded rod.

[0012] Furthermore, a rotating head is fixedly connected to one end of the threaded rod, and the rotating head is rotatably connected to the inner wall of the inner ring positioning seat. The rotating head rotates synchronously with the threaded rod.

[0013] Furthermore, an adjustment head is fixedly connected to the other end of the threaded rod. The longitudinal cross-section of the adjustment head is hexagonal. The adjustment head can be used with a sleeve for knob adjustment, facilitating locking operation.

[0014] Beneficial effects

[0015] The aforementioned adjustable-angle plastic connecting elbow, when the arc-shaped pipe head slides along the surface of the arc-shaped inner pipe, can ensure the connection and sealing between the inner wall of the arc-shaped inner pipe and the inner wall of the arc-shaped pipe head through the sealing ring fixedly connected to the inner wall of the annular groove. This prevents the medium inside the elbow from easily flowing out during the adjustment process. The device, through the structure of the adjustment mechanism and the arc-shaped pipe head, forms an arc shape as a whole. When the arc-shaped pipe head moves the connecting end on the surface of the arc-shaped inner pipe, the angle of the connecting ends of the two connecting ends can be adjusted, reducing the operation steps of adjusting the connecting part and ensuring the working efficiency of the elbow connection.

[0016] The device, through its locking component, can lock the relative position of the arc-shaped inner tube and the arc-shaped tube head when the sliding component and the inner wall of the arc-shaped tube head are adjusted. The device drives the threaded rod to rotate through the knob adjustment head. When the rotating head rotates synchronously with the threaded rod, it drives the inner ring positioning seat to move closer to the threaded sleeve. Through the connecting rod, the arc-shaped inner tube slides along the inner wall of the arc-shaped tube head, thereby achieving the function of adjusting the bending angle of the tube.

Figure 1-4 An adjustable-angle plastic connecting elbow includes two arc-shaped tube ends 1, each end of which is fixedly connected to a connecting end 2; an adjusting mechanism 3, which is disposed between the two arc-shaped tube ends 1, with its surface extending into the interior of the adjacent arc-shaped tube ends 1; wherein the adjusting mechanism 3 includes a sliding component 31 installed between the two arc-shaped tube ends 1, the surface of which extends into the interior of the arc-shaped tube ends 1; and two locking components 32 are installed on the sliding component 31 near the interior of the adjacent arc-shaped tube ends 1, the surfaces of which extend into the interior of the adjacent arc-shaped tube ends 1.

[0027] In some embodiments, such as Figure 2-4 As shown, in a preferred embodiment of the present invention, the sliding component 31 includes an arc-shaped inner tube 311 disposed between two arc-shaped tube heads 1. The transverse interface of the arc-shaped inner tube 311 is arc-shaped. Both ends of the arc-shaped inner tube 311 penetrate into the interior of the adjacent arc-shaped tube head 1. The surface of the arc-shaped inner tube 311 is slidably connected to the inner wall of the adjacent arc-shaped tube head 1. A sealing ring 314 is provided at the end of the arc-shaped inner tube 311. The sealing ring 314 is fixedly connected to the end of the arc-shaped tube head 1 near the connecting end 2. A plurality of annular grooves 312 are opened on the surface of the arc-shaped inner tube 311. A sealing ring 313 is fixedly connected to the inner wall of the annular groove 312. The surface of one of the sealing rings 313 is in contact with the inner wall of the adjacent arc-shaped tube head 1.

[0028] In this embodiment of the utility model, by sliding the two arc-shaped tube heads 1 on the surface of the arc-shaped inner tube 311, the need for adjusting different angles can be achieved. The cooperation between the annular groove 312 and the sealing ring 313 can ensure that the surface of the arc-shaped inner tube 311 and the inner wall of the arc-shaped tube head 1 maintain a good sealing effect during the sliding process. Furthermore, the sealing ring 314 can maintain a sealing effect when the connecting end 2 is fastened to the connecting pipe.

[0029] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 As shown, in a preferred embodiment of the present invention, the locking assembly 32 includes a plurality of connecting rods 323. One side of the connecting rod 323 is fixedly connected to the inner wall of the arc-shaped inner tube 311, and the other side of the connecting rod 323 is fixedly connected to the inner wall of the adjacent arc-shaped tube head 1.

The inner ring positioning seat 321 is located inside the arc-shaped inner tube 311, and the threaded sleeve 322 is located inside the arc-shaped tube head 1.

[0030] The inner wall of the threaded sleeve 322 is threadedly connected to a threaded rod 324. Both ends of the threaded rod 324 extend to the outside of the threaded sleeve 322. One end of the threaded rod 324 is fixedly connected to a rotating head 325, which is rotatably connected to the inner wall of the inner ring positioning seat 321. The other end of the threaded rod 324 is fixedly connected to an adjusting head 326, which has a hexagonal longitudinal section.

[0031] In this embodiment of the utility model, the screw rod 324 is driven to rotate by the knob control head 326. At this time, when the rotating head 325 rotates synchronously with the screw rod 324, it drives the inner ring positioning seat 321 to move closer to the screw sleeve 322. At this time, the arc-shaped inner tube 311 is driven to slide on the inner wall of the arc-shaped tube head 1 by the connecting rod 323, thereby achieving the function of adjusting the angle of the bent tube.
