[0027] Embodiment:

[0028] As shown in the attached Figure 1 to the attached Figure 6 figure:

[0029] The present utility model provides a stainless steel hose joint that is easy to disassemble, including a planetary gear component 1; the planetary gear component 1 includes an outer gear ring 11, a fixed shaft bracket 12 and a sun gear ring 13. The outer gear ring 11 is installed on the outside of the fixed shaft bracket 12, the sun gear ring 13 is installed inside the fixed shaft bracket 12, a planetary gear 1201 is rotatably clamped on the clamping shaft of the fixed shaft bracket 12, the inner side of the planetary gear 1201 meshes with the sun gear ring 13, the outer side of the planetary gear 1201 meshes with the inner side of the outer gear ring 11, a connecting ring 41 is fixedly connected to the front end face of the fixed shaft bracket 12, and a connecting sleeve 2 is fixedly connected inside the sun gear ring 13; a connecting pipe head 5 is threadedly connected to the rear side of the connecting sleeve 2, and a limit ring 3 is clamped on the outside of the front side of the connecting sleeve 2; a linkage plate 42 is clamped on the outside of the connecting ring 41, and the linkage plate 42 and the connecting ring 41 form a linkage component 4.

[0030] As shown in the attached Figure 3 and the attached Figure 4As shown, a connecting pipe 203 is fixedly connected to the rear end of the connecting sleeve 2. The outer wall of the thick pipe section at the front of the connecting sleeve 2 is provided with threads and meshes with the connecting ring 41. The front outer wall of the thick pipe section at the front of the connecting sleeve 2 is fixedly connected with a snap ring 201 and a clamping rod 202. The rear end of the clamping rod 202 is connected to the snap ring 201. After the connecting sleeve 2 is clamped inside the connecting ring 41, the rotation of the connecting ring 41 can drive the connecting sleeve 2 to rotate, and at the same time drive the connecting pipe 203 to rotate, completing the connection with the connecting pipe head 5. After the connection is completed, the rear end face of the thick pipe section of the connecting sleeve 2 fits against the front end face of the fixed shaft frame 12. The thread direction of the connecting sleeve 2 and the thread direction of the connecting pipe 203 can be adjusted according to the actual use situation, so as to determine the rotation direction of connection or disassembly, but it does not affect disassembly.

[0031] As shown in the attached Figure 2 drawing and the attached Figure 3 drawing, a clamping pipe 1202 is fixedly welded to the rear end face of the fixed shaft frame 12. A regular hexagon bayonet is provided inside the clamping pipe 1202. A groove is axially provided on the inner wall of the sun gear ring 13. An inner groove is provided on the outer wall of the outer gear ring 11. The inner groove can be used to more easily grip the outer gear ring 11 for rotation. The rotation of the sun gear ring 13 is driven by the transmission of the planetary gear 1201, and the connection of the stainless steel hose is completed by rotating fewer turns, and the force arm is longer and more labor-saving.

[0032] As shown in the attached Figure 1 drawing, an internal thread nut 501 is fixedly connected to the front end of the connecting pipe head 5. Threads are provided on the inner wall of the internal thread nut 501 and mesh with the connecting pipe 203. During disassembly, the outer gear ring 11 is rotated to drive the connecting ring 41 to rotate, and the connecting pipe 203 is driven to disengage from the internal thread nut 501 through meshing. At the same time, the connecting ring 41 is also driven to move forward, and the extrusion block 4202 is driven to move outwards through the linkage plate 42, realizing the loosening between the connecting sleeve 2 and the hose and achieving rapid disassembly.

[0033] As shown in the attached Figure 6As shown, a pull ring 4101 is fixedly connected to the front end face of the connecting ring 41 by a welding connecting rod. A plug tube 4102 is fixedly connected to the rear end face of the connecting ring 41. A rib is provided on the outer part of the plug tube 4102, and the rib is inserted into a groove on the inner wall of the sun gear ring 13. A connecting block 4201 at the rear end of a linkage plate 42 is fixedly connected to the outer wall of the connecting ring 41. An extrusion block 4202 is fixedly welded to the front end of the linkage plate 42. The extrusion block 4202 is clamped in the limiting groove 301. The inside of the connecting ring 41 is threadedly connected to the connecting sleeve 2. When the outer gear ring 11 is rotated, the sun gear ring 13 is driven to rotate. The sun gear ring 13 drives the connecting ring 41 to rotate through a bar. Through meshing, the connecting sleeve 2 is driven to rotate until it is connected to the connecting pipe head 5. Due to the limitation of the clamping tube 1202, when the outer gear ring 11 is continuously rotated, the planetary gear member 1 as a whole will move backward to clamp the clamping tube 1202 to the outside of the connecting pipe head 5. At the same time as moving backward, the connecting ring 41 is also driven to move backward, synchronously driving the linkage plate 42 to move backward. During the process of the linkage plate 42 moving backward restricted by the pull ring 4101, the extrusion block 4202 will close inwards, and the front end of the connecting sleeve 2 can be pressed tightly, making the hose connected to it tightly.

[0034] As shown in the Figure 6 accompanying drawings, a limiting groove 301 is provided on the inner wall of the limiting ring 3. A clamping groove 302 is provided on the inner wall of the limiting ring 3 at intervals of the limiting groove 301. A clamping rod 202 is clamped in the clamping groove 302. When the connecting sleeve 2 is clamped into the inside of the limiting ring 3, the linkage plate 42 will tighten inwards when moving backward. The limiting groove 301 plays a role in limiting the extrusion block 4202. In this way, the connection of the hose can be ensured to be tight and water leakage can be avoided. And when the connecting ring 41 is rotated in the reverse direction, the linkage plate 42 will be pushed forward, and the extrusion block 4202 will move outwards, and the connection part of the hose will become loose, realizing quick disassembly.

[0035] The specific usage mode and function of this embodiment are as follows:

[0036] In this utility model, the connecting pipe head 5 and the connecting pipe 203 are inserted together. After the hose to be connected is inserted into the outer part of the front section of the connecting sleeve 2, the outer gear ring 11 is rotated to drive the sun gear ring 13 to rotate. The sun gear ring 13 drives the connecting ring 41 to rotate through a bar. Through meshing, the connecting sleeve 2 is driven to rotate until it is connected to the connecting pipe head 5. Due to the limitation of the clamping tube 1202, when the outer gear ring 11 is continuously rotated, the planetary gear member 1 as a whole will move backward to clamp the clamping tube 1202 to the outside of the connecting pipe head 5. At the same time as moving backward, the connecting ring 41 is also driven to move backward, synchronously driving the linkage plate 42 to move backward. During the process of the linkage plate 42 moving backward restricted by the pull ring 4101, the extrusion block 4202 will close inwards, and the hose can be pressed tightly to the outside of the connecting sleeve 2 to complete the connection; rotating the outer gear ring 11 in the reverse direction can quickly complete the disassembly.
