[0038] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0039] Refer to Figure 1 , Figure 3 and Figure 4 , an embodiment provided by the present utility model: A special pipe installation connector includes a pipe 1. Connectors 3 are clamped on both the left and right sides of the outer wall of the pipe 1. Flange edges 4 are fixedly connected to both the left and right sides of the outer wall of the connector 3. Through holes 5 are provided around the outer wall of the flange edge 4. Grooves 6 are provided on both the left and right sides of the inner wall of the connector 3. Rubber rings 7 are fixedly connected to the inner sides of the grooves 6. The rubber rings 7 are clamped with the pipe 1. A positioning mechanism 2 is arranged outside the pipe 1. The positioning mechanism 2 is used to improve the sealing performance of the device;

[0040] Specifically, during installation, the connector 3 is precisely clamped from both the left and right sides of the pipe 1, so that the rubber rings 7 in the grooves 6 on the inner wall of the connector 3 can be closely attached to the pipe 1. By virtue of the excellent elasticity of the rubber, the sealing performance is effectively enhanced, and the possibility of leakage is greatly reduced. Through the flange edges 4 arranged on both the left and right sides of the outer wall of the connector 3 and the carefully provided through holes 5 thereon, fixing parts such as bolts can be conveniently inserted, thereby realizing the firm connection and fixation of the two connectors 3 and the pipe 1 in the middle. At the same time, with the help of the positioning mechanism 2 outside the pipe 1, the position of the connector 3 can be accurately fixed and reasonably adjusted, effectively preventing the connector 3 from loosening due to external forces and other factors, ensuring the sealing performance and stability of the entire pipe 1, and providing a reliable guarantee for the normal operation of the pipe.

[0041] Reference Figure 1 、 Figure 2 and Figure 5 The positioning mechanism 2 includes a fixing groove 201 which is formed on the outer side of the pipeline 1. A first sealing plate 202 is arranged on the inner side of the fixing groove 201. A second sealing plate 204 is arranged on the front side of the first sealing plate 202. A hinge 203 is fixedly connected to the outer side of the second sealing plate 204. The second sealing plate 204 is rotatably connected to the first sealing plate 202 through the hinge 203. A clamping plate 205 is rotatably connected to the bottom of the first sealing plate 202. A clamping groove plate 206 is fixedly connected to the bottom of the second sealing plate 204. The clamping plate 205 is engaged with the clamping groove plate 206;

[0042] Specifically, by carefully placing the first sealing plate 202 in the fixing groove 201 on the outer side of the pipeline 1, during the installation operation, making full use of the flexibility of the hinge 203 to rotate the second sealing plate 204, making it slowly approach and closely fit the first sealing plate 202, thus forming a comprehensive enclosure for the pipeline. Then, by skillfully rotating the clamping plate 205 at the bottom of the first sealing plate 202 to a position corresponding to the clamping groove plate 206 at the bottom of the second sealing plate 204 and accurately snapping it into the clamping groove plate 206, a firm fixation is achieved. Such a design can effectively prevent the substances in the pipeline 1 from leaking, providing a solid and stable support and reliable protection for the pipeline. Even in the face of external vibration or pressure, due to the tightly engaged structure between the clamping plate 205 and the clamping groove plate 206, it can always maintain good sealing performance and stable fixation effect.

[0043] Reference Figure 1 、 Figure 2 and Figure 4 Installation grooves 8 are formed around the outer wall of the rubber ring 7. Rubber blocks 9 are fixedly connected to the inner sides of the installation grooves 8. A screw 10 is rotatably connected to the inner side of the through hole 5. A threaded sleeve 11 is threadedly connected to the outer side of the screw 10. A handle 12 is fixedly connected to the top of the outer wall of the connecting member 3. A sheath 13 is fixedly connected to the outer side of the handle 12;

[0044] Specifically, through the rubber blocks 9 installed inside, the sealing performance of the rubber ring 7 can be improved. Through the connection between the screw 10 and the threaded sleeve 11, the stability of multiple connecting members 3 after assembly can be improved. This connection method can withstand large external forces and vibrations, ensuring the stability of the entire connection structure.

[0045] Reference Figure 2 、 Figure 3 and Figure 5, positioning blocks 14 are fixedly connected to both the front and rear sides of the outer wall of the connecting member 3, and positioning holes 15 are provided on the outer sides of the positioning blocks 14; a bottom plate 16 is fixedly connected to the bottom of the connecting member 3, and brackets 17 are fixedly connected to the peripheries of the outer walls of the bottom plate 16; a reserved groove 18 is provided in the middle of the inner wall of the connecting member 3, and a filter screen 19 is fixedly connected to the inner side of the reserved groove 18;

[0046] Specifically, by installing threaded parts in the positioning holes 15 on the positioning blocks 14, the installation and fixation operations of the device can be very conveniently carried out. Through the bottom plate 16 and the brackets 17 thereon, the stability of the device during fixation can be effectively improved, making it more firm and reliable. By installing the filter screen 19 in the reserved groove 18, effective filtration can be provided for the materials transported in the pipeline, ensuring the quality of the materials.

[0047] Working principle: Before using this device, first, during installation, the connecting member 3 is snapped from the left and right sides of the pipeline 1. At this time, the rubber ring 7 in the inner wall groove 6 of the connecting member 3 is in close contact with the pipeline 1, and the elasticity of the rubber is used to increase the sealing performance. Then, the flange edges 4 on the left and right sides of the outer wall of the connecting member 3 and the through holes 5 provided thereon can be used to insert fixing parts such as bolts to realize the connection and fixation of the two connecting members 3 and the middle pipeline 1. At the same time, the positioning mechanism 2 on the outer side of the pipeline 1 further improves the sealing performance of the device. By fixing and adjusting the position of the connecting member 3, loosening of the connecting member 3 caused by external forces and other factors can be prevented, ensuring the sealing and stability of the entire pipeline 1;

[0048] The first sealing plate 202 is placed in the fixing groove 201 on the outer side of the pipeline 1. During installation, the second sealing plate 204 is rotated through the hinge 203 to make it approach and fit the first sealing plate 202 to form an enclosure around the pipeline. Subsequently, the clamping plate 205 at the bottom of the first sealing plate 202 rotates to the corresponding position of the clamping groove plate 206 at the bottom of the second sealing plate 204 and is snapped into it for fixation, which can prevent the leakage of substances in the pipeline 1, provide stable support and protection for it. Even under external vibration or pressure, good sealing and fixation effects can be maintained by virtue of the clamping structure between the clamping plate 205 and the clamping groove plate 206.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
