Compared with the prior art, the utility model has the following beneficial effects:

(1) The sealing water ring provided by the utility model has the advantages that the main body is composed of multiple sections of same arc blocks, and the sealing water ring is convenient to install and detach.

(2) The telescopic device penetrates through the outer side of the outer ring of the sealing ring and is connected with the fixed block, and the inner part can be installed on the outer side of the outer ring of the sealing ring, so that the installation difficulty is reduced, and the later-stage part is replaced.

(3) The rubber block is arranged on the concave surface of the fixed block, friction is increased during use, the fixed block is more stable during use, and the loosening probability is reduced.

Of course, it is not necessary for any one product to practice the utility model to achieve all of the advantages set forth above at the same time.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be understood that the terms "one side," "one end," "the other end," "the outside," "the inside," and the like indicate an orientation or a positional relationship, and are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-6, a sealing water ring of the present utility model mainly includes a sealing ring outer ring 1, a telescoping device 2 installed through the sealing ring outer ring 1, and a fixing block 3 connected with the telescoping device.
