[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 and Figure 2 The utility model provides an embodiment of a pipe connection mechanism with high sealing performance, including a connecting plate 1, a connecting plate 2 2 being hingedly connected to the rear side of the connecting plate 1, the connecting plate 1 and the connecting plate 2 2 being the main components of the pipe connection mechanism, and being used to connect two sections of water pipes 3 to realize the communication of the pipes, a fixing component being fixedly connected to the inner side of the connecting plate 1, the fixing component including a plug-in pipe 41, and being used to connect the two sections of water pipes 3, and at the same time being used to enhance the sealing performance of the connection through a sealing ring 46, and ensuring the sealing between the water pipe 3 and the plug-in pipe 41, the plug-in pipe 41 is fixedly connected to the inner wall of the connecting plate 1, and a sealing ring 46 is provided on the outer side of the plug-in pipe 41, and a plurality of sealing rings 46 are provided, which surround the outer side of the plug-in pipe 41 and seal the inner side of the water pipe 3 to prevent liquid leakage, and water pipes 3 are provided on the left and right sides of the plug-in pipe 41, and the inner sides of the connecting plate 1 and the connecting plate 2 2 are fitted on the outer side of the water pipe 3, which can improve the stability of the water pipe 3.

[0031] Furthermore, the inner wall of the connecting plate 2 is slidably connected to an extrusion plate 42, which is moved downward to cooperate with the plug-in tube 41 to fix and squeeze the water pipe 3, thereby enhancing the stability of the connection. The inner wall of the top end of the extrusion plate 42 is rotatably connected to a threaded rod 44, and the threaded rod 44 is rotated by the crank 45 to move the extrusion plate 42 up and down, thereby achieving extrusion and fixation of the water pipe 3. The threaded rod 44 is threadedly connected to the inner wall of the connecting plate 2, and the top of the threaded rod 44 is fixedly connected to the crank 45, which is convenient for the operator to rotate the threaded rod 44. The bottom end of the extrusion plate 42 is fixedly connected to a fixing bar 43, and multiple groups are provided to increase the contact area between the extrusion plate 42 and the water pipe 3 or enhance the fixing effect.

[0032] Reference Figure 1 - Figure 3A limiting assembly is provided on the front side of the connecting plate 1, and the limiting assembly includes a fixed block 51, which cooperates with the limiting block 55 to realize the limiting and fixing of the connecting plate 1 and the connecting plate 2 through the limiting rod 52. The rear side of the fixed block 51 is fixedly connected to the front side of the connecting plate 1, and the front side of the connecting plate 2 is fixedly connected to the limiting block 55, providing moving space for the limiting rod 52, and the top end of the fixed block 51 slides inside the limiting block 55.

[0033] Furthermore, the inner wall of the limit block 55 is slidably connected to the limit rod 52, which slides on the inner wall of the limit block 55 and is threadedly connected to the inner wall of the fixed block 51 to achieve the limitation and fixation of the connecting plate 1 1 and the connecting plate 2 2. The outer side of the limit rod 52 is rotatably connected to the baffle 53, which, under the action of the compression spring 54, limits and fixes the limit rod 52. The right side of the baffle 53 is elastically connected to the limit block 55 through the compression spring 54, which provides elastic force for the baffle 53 so that the baffle 53 can press the limit rod 52 to ensure the stability of the position of the limit rod 52 and prevent loosening caused by vibration. A threaded groove is provided on the left side of the limit rod 52, and the left side of the limit rod 52 is threadedly connected to the inner wall of the fixed block 51. The stability of the limit rod 52 can be increased through the threaded groove.

[0034] Working principle: During use, when connecting the pipes, place the two sections of water pipe 3 on the left and right sides of the plug-in pipe 41 on the inner side of the connecting plate 1, and then rotate the connecting plate 2 2 around the hinge so that the inner sides of the connecting plate 1 and the connecting plate 2 2 are attached to the outer side of the water pipe 3. During the closing process of the connecting plate 1 and the connecting plate 2 2, the top of the fixed block 51 slides into the inner side of the limit block 55, pushing the limit rod 52 to slide on the inner wall of the limit block 55. The baffle 53 on the outer side of the limit rod 52 limits and fixes the limit rod 52 under the elastic action of the compression spring 54, preventing the limit rod 52 from loosening due to vibration.

[0035] When the limiting rod 52 slides to a suitable position, the threaded groove on the left side of the rotating limiting rod 52 is threadedly connected to the inner wall of the fixing block 51, further increasing the stability of the limiting rod 52, thereby achieving the limitation and fixation of the connecting plate 1 and the connecting plate 2 2.

[0036] At this time, turning the crank 45 drives the threaded rod 44 to rotate. The rotation of the threaded rod 44 causes the extrusion plate 42 to move downward. The fixing strip 43 at the bottom end of the extrusion plate 42 cooperates with the plug-in tube 41 to fix and squeeze the water pipe 3, thereby enhancing the stability of the connection. At the same time, the multiple sets of sealing rings 46 on the outside of the plug-in tube 41 play a sealing role to prevent liquid leakage.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
