[0019] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0020] See also Figures 1 to 4, an adjustable rubber ring, comprising: a rubber ring body and a plurality of steel balls 3; the rubber ring body comprises a main body 4 and a plug-in part 5, the main body 4 is C-shaped, one end of the main body 4 is fixedly connected to one end of the plug-in part 5, and the other end of the main body 4 is provided with a slot 6 for the plug-in part 5 to be inserted, the slot 6 runs through the inner and outer sides of the main body 4, when the plug-in part 5 is inserted into the slot 6, the rubber ring body forms a closed-loop structure, the outer side of the plug-in part 5 is flush with the outer side of the rubber ring body, the inner side of the plug-in part 5 is flush with the inner side of the rubber ring body, an adjustment space is provided between the bottom of the slot 6 and the plug-in part 5, the plug-in part 5 can slide along the slot 6 to adjust the radius of the rubber ring; a plurality of steel balls 3 are arranged in the adjustment space in sequence along the circumference of the closed-loop structure, the steel balls 3 support the side walls of the slot 6, and the diameter of the steel balls 3 is smaller than the thickness t of the rubber ring body.

[0021] Through the above arrangement, firstly, the plug-in portion 5 can slide along the slot 6 to adjust the radius of the rubber ring; secondly, the steel ball 3 can support the side wall of the slot 6 to prevent the side wall of the slot 6 from deforming during use and affecting the waterproof effect.

[0022] In this application, the rubber ring body is an integrated structure, and the material of the rubber ring body can be set to rubber so that the rubber ring body has better elastic performance; when installing, refer to Figure 2 , insert the plug-in part 5 into the slot 6. When the insertion depth of the plug-in part 5 increases, the outer diameter of the rubber ring decreases and the adjustment space decreases; when the insertion depth of the plug-in part 5 decreases, the outer diameter of the rubber ring increases and the adjustment space increases; by adjusting the insertion depth of the plug-in part 5, the radius of the rubber ring is adapted to the inner diameter of the pipe to be connected, that is, after the rubber ring is installed, the outer side of the rubber ring fits with the inner wall of the pipe, thereby achieving a better sealing effect; insert the steel ball 3 into the adjustment space, and the steel ball 3 supports the side wall of the slot 6. During use, when the water pressure outside is large, the water pressure will not flatten the slot 6, thereby improving the stability of the rubber ring body and preventing the slot 6 from deforming and leaking.

[0023] As an implementation method, the rubber ring body also includes: a first flange 8 and a second flange 9; a first flange 8 extending inward is fixedly connected to the side wall of the slot 6, and the first flange 8 supports the outer side of the steel ball 3 to prevent the steel ball 3 from moving outward; a second flange 9 extending inward is fixedly connected to the side wall of the slot 6, and the second flange 9 supports the inner side of the steel ball 3 to prevent the steel ball 3 from moving inward.

[0024] Through the above arrangement, firstly, the stability of the steel ball 3 can be increased to prevent the steel ball 3 from falling out of the adjustment space when the rubber ring is installed; secondly, the rigidity of the rubber ring body at the slot 6 can be increased, and the slot 6 is less likely to be flattened by water pressure, thereby ensuring good sealing.

[0025] In the present application, the first flange 8, the second flange 9 and the rubber ring body are an integrally formed structure; when the steel ball 3 is inserted into the adjustment space, the first flange 8 and the second flange 9 can prevent the steel ball 3 from falling out of the adjustment space to facilitate the installation of the rubber ring; in addition, the first flange 8 and the second flange 9 act as reinforcing ribs, and the slot 6 is less likely to be flattened by water pressure, thereby ensuring good sealing.

[0026] As an implementation method, a first avoidance groove 10 for avoiding the first flange 8 is provided on the outer side of the plug-in part 5, and the first flange 8 is embedded in the first avoidance groove 10. A second avoidance groove 11 for avoiding the second flange 9 is provided on the inner side of the plug-in part 5, and the second flange 9 is embedded in the second avoidance groove 11.
