DETAILED DESCRIPTION

[0023] 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 creative work are within the scope of protection of the present invention.

[0024] like Figures 1-4 As shown, the embodiment of the present invention provides a large bottom shaft docking telescopic water-stopping device, including a connecting base ring 200 arranged between two bottom shafts 100, and symmetrically provided with docking positioning rings 201 at both ends of the connecting base ring 200 that match the grooves at the ends of the bottom shaft 100. The ends of the docking positioning rings 201 are rounded, and the docking positioning rings 201 and the connecting base ring 200 can be integrally formed. A middle through-hole 202 is provided between the docking positioning ring 201 and the connecting base ring 200. By providing the middle through-hole 202, material loss can be greatly reduced and the weight of the components can be reduced. The connecting base ring 200 is made of rubber material and uses its own elasticity to achieve sealing;

[0025] The connecting base ring 200 can also be set to a detachable structure to facilitate later maintenance. The connecting base ring 200 includes a first connecting ring 213 and a second connecting ring 214. Each of the first connecting ring 213 and the second connecting ring 214 is integrally formed with the docking positioning ring 201. A first connecting sleeve 211 is provided at the inner end of the first connecting ring 213, and a second connecting sleeve 210 is provided at the inner end of the second connecting ring 214. The second connecting sleeve 210 is slidably arranged on the inner side of the first connecting sleeve 211. A sealing member matching the second connecting sleeve 210 is provided on the inner wall of the first connecting sleeve 211. An expansion member is further provided between the first connecting sleeve 211 and the second connecting sleeve 210, so that the first connecting sleeve 211 and the second connecting sleeve 210 are docked and fixed with the two bases after installation through the expansion member;

[0026] The expansion member includes a telescopic rod 203 disposed inside a first connecting sleeve 211. A telescopic sleeve 206 is provided on the outer sliding sleeve of the telescopic rod 203 to press against the inside of a second connecting ring 214. The telescopic sleeve 206 and the telescopic rod 203 are connected by an expansion spring 204. Under the action of the expansion spring 204, the second connecting ring 214 and the first connecting ring 213 are kept apart. During subsequent maintenance, it is only necessary to push the second connecting ring 214 and the first connecting ring 213 to slide relative to each other, and then remove the entire member from the gap between the two bottom shafts.

[0027] A through hole 212 is provided in the middle of the first connecting ring 213 and the second connecting ring 214;

[0028] The sealing member includes at least one sealing ring 205, which seals the gap between the first connecting sleeve 211 and the second connecting sleeve 210, thereby making the two connected in a sealed manner;

[0029] The first connecting ring 213 and the first connecting sleeve 211, the second connecting ring 214 and the first connecting sleeve 211 are connected by a connecting piece, and the connecting piece includes a clamping protrusion 207 arranged on the inner side of the docking positioning ring 201, and a connecting ring 208 matching the clamping protrusion 207 is provided on the inner side of the first connecting sleeve 211. The clamping protrusion 207 and the connecting ring 208 are connected by multiple bolts 209, which facilitates subsequent disassembly and assembly.

[0030] Working principle: In actual use, the docking positioning rings 201 on both sides of the connecting base ring 200 are respectively inserted into the grooves at the ends of the two bottom shafts 100 to complete the installation. The connecting base ring 200 can be optimized later to construct a split structure to facilitate alignment and thickness adjustment, which can adapt to the installation between bottom shafts without gaps. During later maintenance, it is only necessary to push the second connecting ring 214 and the first connecting ring 213 to make the first connecting ring 213 and the second connecting ring 214 slide relative to each other, and then remove the entire component from the gap between the two bottom shafts.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
