[0003] The existing steel-plastic conversion joint is connected to the steel pipe through a steel threaded joint and to the plastic pipe through a plastic pipe. When connecting the steel pipe and the plastic pipe through the steel-plastic conversion joint, if the personnel first connect the conversion joint to the steel pipe and then connect the plastic pipe to the conversion joint, since the plastic pipe needs to be put on the outside of the conversion joint, in order to facilitate the joint to enter the plastic pipe, the personnel will use a rotational insertion method to put the plastic pipe on the outside of the conversion joint. During the rotational insertion process, the connection between the conversion joint and the steel pipe may become loose. If the conversion joint is connected to the plastic pipe first, then when the conversion joint is assembled with the steel pipe, the plastic pipe needs to be rotated together, resulting in defects in the installation of the conversion joint.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Embodiment 1
[0022] See also Figure 1 , Figure 2 The figure shows a steel-plastic conversion joint connection structure, including a joint structure 1 for connecting a steel pipe and a plastic pipe, the joint structure 1 includes a connecting pipe 101, a plastic pipe joint 102 is fixedly embedded at the left end of the connecting pipe 101, a steel pipe joint 103 is rotatably installed at the right end of the connecting pipe 101, a gear ring 2 is fixedly sleeved on the outer side of the steel pipe joint 103, and the left end of the gear ring 2 is movably abutted against the right end of the connecting pipe 101; a limiting component 3 is used to limit the gear ring 2, and the limiting component 3 is installed on the outer side of the connecting pipe 101.
[0023] See also Figure 3 The right end of the plastic pipe joint 102 and the left end of the steel pipe joint 103 are located inside the connecting pipe 101, and the left end of the plastic pipe joint 102 is movably abutted against the right end of the steel pipe joint 103, and the connecting pipe 101 is made of metal.
[0024] See also Figure 3 The outer side of the steel pipe joint 103 is located on the left side of the gear ring 2 and is movably sleeved with an anti-slip ring 104. The anti-slip ring 104 can prevent the steel pipe joint 103 from detaching from the connecting pipe 101, and the anti-slip ring 104 and the connecting pipe 101 are an integrally formed structure. The outer sides of one end of the plastic pipe joint 102 and the steel pipe joint 103 that abut each other are movably sleeved with a rubber sleeve 105. The rubber sleeve 105 can enhance the sealing between the steel pipe joint 103 and the connecting pipe 101, and the rubber sleeve 105 is fixedly embedded in the inside of the connecting pipe 101.
[0025] The working principle of the steel-plastic conversion joint is easy to install: when connecting the steel pipe and the plastic pipe through the joint structure 1, the personnel can first dock the plastic pipe joint 102 with the plastic pipe, and then dock the steel pipe joint 103 with the steel pipe. When docking the steel pipe, the personnel will move the limit component 3 to the left, and then the steel pipe joint 103 can be rotated alone to make the steel pipe joint 103 and the steel pipe thread docking without rotating the joint structure 1 as a whole. The personnel can also dock the joint structure 1 with the steel pipe first, and then dock the plastic pipe with the plastic pipe joint 102. When docking, the limit component 3 is also moved to the left to avoid driving the steel pipe joint 103 to rotate inside the steel pipe when the plastic pipe is rotated and sleeved onto the plastic pipe joint 102, thereby affecting the sealing of the connection between the steel pipe joint 103 and the steel pipe. By arranging the steel pipe joint 103 to rotate inside the connecting pipe 101, the operation is more flexible and the installation is more convenient when installing the joint structure 1.
[0026] Embodiment 2
[0027] See also Figure 3 This embodiment further explains Example 1. The limiting assembly 3 includes a retaining ring 301 fixedly sleeved on the outside of the connecting tube 101. The outer side of the retaining ring 301 is movably sleeved with an adjusting tube 302. The outer side of the gear ring 2 is movably sleeved with a silicone ring 303. The silicone ring 303 is sleeved on the outer side of the gear ring 2 to prevent the gear ring 2 from rotating, and the silicone ring 303 is fixedly embedded in the inside of the adjusting tube 302.
[0028] See also Figure 3 The outer ring diameter of the gear ring 2 is larger than the inner ring diameter of the silicone ring 303. The interior of the adjusting tube 302 is located on the left side of the silicone ring 303 and is fixedly embedded with a second retaining ring 304. The inner ring diameters of the silicone ring 303 and the second retaining ring 304 are equal to the outer diameter of the connecting tube 101. The interior of the adjusting tube 302 is located on the left side of the second retaining ring 304 and is also fixedly provided with a plurality of convex strips 305 equidistantly distributed around the circumference. The convex strips 305 can prevent the adjusting tube 302 from rotating outside the connecting tube 101.
[0029] See also Figure 4 The convex strip 305 is movably embedded in the outer side of the retaining ring 1 301 , and the outer side of the connecting pipe 101 is located between the retaining ring 1 301 and the retaining ring 2 304 and is movably sleeved with a spring 306 .
[0030] In this embodiment: after the steel pipe joint 103 is connected to the steel pipe, the personnel moves the adjusting tube 302 to the right so that the silicone ring 303 inside the adjusting tube 302 is sleeved on the outside of the toothed ring 2. Since the inner ring diameter of the silicone ring 303 is smaller than the outer ring diameter of the toothed ring 2, when the silicone ring 303 is sleeved on the outside of the toothed ring 2, the steel pipe joint 103 cannot rotate in the connecting tube 101 due to the restriction of the silicone ring 303 on the toothed ring 2, so that the steel pipe joint 103 can be locked to prevent the steel pipe joint 103 from rotating inside the connecting tube 101, which is beneficial to avoid the steel pipe joint 103 rotating and causing the steel pipe and the joint structure 1 to loosen.
[0031] Embodiment 3
[0032] See also Figure 4 This embodiment further illustrates other embodiments that a plurality of convex rings 4 distributed at equal distances are fixedly embedded on the outer side of the regulating tube 302 .
[0033] In this embodiment, when a person moves the adjusting tube 302 , a plurality of convex rings 4 distributed at equal distances can increase the friction between the finger and the adjusting tube 302 , making it easier for the person to move the adjusting tube 302 .
