[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Refer to Figure 1 - Figure 3 As shown in the figure, an embodiment provided by the present invention: a convenient installation elbow with high sealing performance, including a pipe body 1 for connecting pipelines. A sealing assembly 2 for increasing the connection sealing performance between the pipe body 1 and the pipeline is arranged on the outer wall of the pipe body 1. The sealing assembly 2 includes a fixed ring 21 for supporting the plastic elastic piece 22. The fixed ring 21 is fixedly connected to the right end of the pipe body 1. A plastic elastic piece 22 for squeezing the rubber sleeve 23 is fixedly connected to the right end of the sealing assembly 2. A fixing assembly 3 for fixing the pipe body 1 is arranged on the outer wall of the pipe body 1.

[0031] Refer to Figure 1 、 Figure 2 And Figure 4 As shown in the figure, the fixing assembly 3 includes a fixed frame 31 for supporting the pipe body 1. The fixed frame 31 is hinged on the outer wall of the pipe body 1. A fixed plate 32 for fixing the whole device is rotatably connected to the top of the fixed frame 31. Installation grooves 33 for installing bolts are arranged near the left and right sides of the top of the fixed plate 32. By using bolts, the fixed plate 32 can be installed at the fixed plane, so as to increase the stability of the support of the pipe body 1. The sealing assembly 2 further includes a threaded sleeve 24 for squeezing the plastic elastic piece 22. The threaded sleeve 24 is threadedly connected to the outer wall of the plastic elastic piece 22. By rotating the threaded sleeve 24, the threaded sleeve 24 can be engaged with the plastic elastic piece 22. An anti-slip block 25 for facilitating the operator to rotate the threaded sleeve 24 is fixedly connected to the outer wall of the threaded sleeve 24. A rubber sleeve 23 for squeezing the pipeline is fixedly connected to the inner wall of the plastic elastic piece 22.

[0032] Refer to Figure 1 - Figure 3The left end of the threaded sleeve 24 is rotatably connected to a sliding sleeve 26 for supporting the threaded sleeve 24. The outer wall of the tube body 1 is fixedly connected to a fixed sleeve 28 for limiting the movement of the sliding sleeve 26. The sliding sleeve 26 slides on the inner wall of the fixed sleeve 28. The sliding sleeve 26 can only slide left and right and will not rotate on the inner wall of the fixed sleeve 28. The front end of the sliding sleeve 26 is fixedly connected to a plastic clip 27 for fixing the sliding sleeve 26. The front end of the plastic clip 27 is set near the right end and is inclined. When the inclined surface is squeezed, the plastic clip 27 will bend inward. The plastic clip 27 and the plastic spring piece 22 are both made of plastic material and have elastic deformation ability. They will be elastically deformed when squeezed. The inner wall of the fixed sleeve 28 is provided with a fixing groove 210 for accommodating the plastic clip 27. The material buckle 27 is adapted to the fixing groove 210. When the plastic buckle 27 is inserted into the fixing groove 210, the sliding sleeve 26 will be fixed and cannot move to the left. The front end of the fixing sleeve 28 is slidably connected to the slide plate 29 for driving the push block 211 to move. The rear end of the slide plate 29 is fixedly connected to the push block 211 for pushing the plastic buckle 27. The fixing ring 21 is adapted to the fixing groove 210. By pushing the slide plate 29, the push block 211 can be driven to push the plastic buckle 27 out of the fixing groove 210. There are multiple groups of plastic buckles 27 and slide plates 29. The multiple groups of plastic buckles 27 and slide plates 29 are symmetrically arranged with the center line of the sliding sleeve 26 as the axis of symmetry. The two groups of plastic buckles 27 can fix the sliding sleeve 26 from both ends at the same time, so that the stability when fixed is better.

[0033] Working principle: When it is necessary to connect the pipelines, the tube body 1 can be first sleeved on the outer walls of the two sets of pipelines, and then the threaded sleeve 24 can be rotated to drive it to engage with the plastic spring piece 22. The threaded sleeve 24 will squeeze the plastic spring piece 22 and move to the right. The plastic spring piece 22 will be elastically deformed under the squeezing, and at the same time, the plastic spring piece 22 will squeeze the rubber sleeve 23 to make it shrink evenly. The rubber sleeve 23 will squeeze the pipeline, so as to ensure the sealing of the connection between the pipeline and the overall device. When the threaded sleeve 24 can no longer rotate, the threaded sleeve 24 can be loosened, and the plastic buckle 27 will be stuck in the inside of the fixing groove 210 to fix the sliding sleeve 26. At this time, the sliding sleeve 26 will not be able to move to the left, and the threaded sleeve 24 will also be unable to move to the left.

[0034] After the pipes are connected, the fixing plate 32 can be fixed to the fixed plane using bolts, thereby increasing the stability of the entire device during use.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
