[0023] As Figures 1-5 shown, the present utility model provides a technical solution: a rubber hose joint convenient for docking, including a fixed column 1. A fixed rod 3 is fixedly connected to the side surface of the fixed column 1. The fixed rod 3 penetrates and is threadedly connected with a bolt 4. The top surface and the bottom surface of the fixed column 1 are both rotatably connected with a linkage plate 5, and the two groups of linkage plates 5 are fixedly connected through a connecting block 6. A limit hole 7 is opened on the surface of the linkage plate 5. A connecting part 2 is arranged inside the fixed column 1. The connecting part 2 includes: a fixed disk 21, an upper rotating plate 22, a lower rotating plate 23, a first arc-shaped groove 24, a second arc-shaped groove 25, a sliding groove 26, a through groove 27, an upper sliding block 28, an upper connecting plate 29, an upper sliding rod 210, a push rod 211, a pushing clamping block 212, a lower sliding block 213, a lower connecting plate 214, a lower sliding rod 215, a pulling rod 216, a pulling clamping block 217, a positioning rod 218, a spring 219, and a cylinder 220.

[0024] The side of the fixed disk 21 is fixedly connected to the inner wall of the fixed column 1, and the inner wall of the fixed column 1 is rotatably connected with an upper rotating plate 22 and a lower rotating plate 23. The top surface of the lower rotating plate 23 is provided with an arc groove 1 24, and the surface of the upper rotating plate 22 is provided with an arc groove 25. The sliding groove 26 is provided on the surface of the fixed disk 21, and the inner side of the sliding groove 26 is slidably connected with an upper slider 28 and a lower slider 213. A through groove 27 is provided on the inner side of the sliding groove 26, and the bottom surface of the upper slider 28 is fixedly connected with an upper connecting plate 29, and the top surface of the lower slider 213 is fixedly connected with a lower connecting plate 214. The top surface of the upper slider 28 is fixedly connected with an upper slider 210. The linkage plate 5 rotates to drive the cylinder 220 to rotate together, and the cylinder 220 drives the upper rotating plate 22 to rotate. When the upper rotating plate 22 rotates, it will contact the upper slider 210 through the arc groove 1 24, thereby forcing the upper slider 210 to slide along the arc groove 1 24, and then the upper slider 210 gradually slides toward the center of the fixed column 1. The bottom surface of the lower slider 213 is fixedly connected with a lower slider 215. The upper slider 210 penetrates the arc groove 25 provided on the surface of the upper rotating plate 22, and the lower slider 215 penetrates the arc groove 1 24 provided on the surface of the lower rotating plate 23. The upper slide bar 210 passes through and is fixedly connected with a push rod 211. One end of the push rod 211 away from the upper slide bar 210 is fixedly connected to a push clamp 212. The upper slide bar 210 gradually slides toward the center of the fixed column 1, and the upper slide bar 210 pushes the push rod 211 to drive the push clamp 212 to clamp the outer side of the rubber hose. The lower sliding rod 215 passes through and is fixedly connected with a pull rod 216. The upper connecting plate 29 will slide along the through groove 27 and compress the spring 219 at the same time. The arc groove 25 on the surface of the lower rotating plate 23, which is opposite to the arc groove 1 24, will drive the lower sliding rod 215 to slide together, so that the lower sliding rod 215 drives the pull rod 216 to move in the direction away from the center of the fixed column 1. The end of the pull rod 216 away from the lower sliding rod 215 is fixedly connected with a pulling clamp 217. The lower sliding rod 215 drives the pull rod 216 to move in the direction away from the center of the fixed column 1, and the pull rod 216 will pull the pulling clamp 217 to clamp the inner wall of the rubber hose, and shorten the distance between the pushing clamp 212 and the pulling clamp 217, so that the outer wall and the inner wall of the rubber hose are in contact with each other through the pushing clamp 212 and the pulling clamp 217.A positioning rod 218 is fixedly connected to the inner side of the through slot 27. The positioning rod 218 penetrates the upper connecting plate 29 and the lower connecting plate 214. The right side of the upper connecting plate 29 and the left side of the lower connecting plate 214 are fixedly connected with a spring 219. When the upper slide bar 210 slides, the upper slide 28 will be driven to slide along the slide slot 26. At the same time, the upper connecting plate 29 will slide along the through slot 27, and the spring 219 will be compressed. A cylinder 220 is fixedly connected to the top surface of the upper rotating plate 22. The end of the cylinder 220 away from the upper rotating plate 22 is fixedly connected to the inner side of the linkage plate 5. When the rubber hose is connected, the rubber hose is inserted into the fixed column 1 so that the inner wall of the rubber hose fits the surface of the pulling clamp 217. At this time, the linkage plate 5 is rotated, and the linkage plate 5 will drive the cylinder 220 to rotate together. The number of the connecting parts 2 is two groups, and the two groups of connecting parts 2 are symmetrically arranged with the center line of the push rod 211 as the symmetry axis.

[0025] Based on the above embodiment, when the rubber hose is connected, the rubber hose is inserted into the fixed column 1 so that the inner wall of the rubber hose fits with the surface of the pulling clamp 217. At this time, the linkage plate 5 is rotated, and the linkage plate 5 will drive the cylinder 220 to rotate together, and the cylinder 220 will drive the upper rotating plate 22 to rotate. When the upper rotating plate 22 rotates, it will contact the upper sliding rod 210 through the arc groove 1 24, thereby forcing the upper sliding rod 210 to slide along the arc groove 1 24, and then the upper sliding rod 210 gradually slides toward the center of the fixed column 1, and the upper sliding rod 210 will push the push rod 211 to drive the pushing clamp 212 to clamp the outer side of the rubber hose, and when the upper sliding rod 210 slides, it will drive the upper sliding block 28 along The slide groove 26 slides, and the upper connecting plate 29 slides along the through groove 27, and the spring 219 is compressed at the same time. The arc groove 25 on the surface of the lower rotating plate 23, which is opposite to the arc groove 1 24, drives the lower slide rod 215 to slide together, and then the lower slide rod 215 drives the pull rod 216 to move away from the center of the fixed column 1, and the pull rod 216 pulls the pulling clamp 217 to clamp the inner wall of the rubber hose, and shortens the distance between the pushing clamp 212 and the pulling clamp 217. The outer wall and the inner wall of the rubber hose are contacted by pushing the clamp 212 and the pulling clamp 217, so that the rubber hose can be more tightly fixed inside the fixed column 1, and the hose can be prevented from being stretched and deformed when it is connected.

[0026] After the linkage plate 5 is rotated a certain distance and the rubber hose is firmly fixed, the bolt 4 is rotated to insert the bolt 4 into the limiting hole 7 opened on the surface of the linkage plate 5, so that the linkage plate 5 is limited, and the symmetrically arranged connecting part 2 can make the symmetrical rubber hoses more stably docked, and the operation is simple, convenient and fast.

[0027] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made to it, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are all within the protection scope of the present utility model.
