The shape of the cover body 5-1 is the same as that of the anchor sealing end of the anchor plate 3, and the size is the same as or slightly larger than that of the anchor sealing end of the anchor plate 3, so that the cover body 5-1 tightly covers the anchor sealing end of the anchor plate 3; the handle 5-2 is integrally arranged or fixedly connected on the cover body 5-1 so as to facilitate the disassembly, assembly and taking of the sealing cover 5.
Referring to fig. 1, 2, 7 and 8, the positioning structure of the anchor capable of rapidly sealing the anchor is composed of an anchor plate ring 3-1, a sealing lip 12 and a buckle 7. The anchor plate ring 3-1 is made of steel or hard plastic and is integrally arranged on the outer side of the anchor sealing end of the anchor plate 3 or is fixedly connected to the outer side of the anchor sealing end of the anchor plate 3 in a screw mode, a strong glue mode and the like. The anchor plate ring 3-1 can be set to be square or round according to the shape of the anchor plate 3 because the shape of the anchor plate 3 is square or round. The sealing lip 12 is an annular plate, has the same shape as the opening end of the cover body 5-1, is integrally arranged on the outer edge of the opening end of the cover body 5-1, and can be attached to one side end face of the anchor sealing end of the anchor plate ring 3-1. After the sealing lip 12 is attached to the anchor plate ring 3-1, the periphery of the sealing lip 12 is superposed with the periphery of the anchor plate ring 3-1; the cover body 5-1 covers the end part of the anchor plate 3 at the anchor sealing end. The rubber ring 6 is wrapped on the outer side of the joint of the cover body 5-1 and the anchor plate ring 3-1, so that a sealing effect is achieved. The rubber ring 6 is externally provided with a buckle 7 in a clamping way. The buckle 7 is of a pipe clamp structure, clamps the lip joint and the anchor plate ring 3-1 which are jointed together in a wrapping mode, clamps the rubber ring 6 and improves the stability of the sealing cover.
Referring to fig. 3, the anchor plate 3 of the anchor device for rapidly sealing the anchor is of a circular structure. The positioning structure is composed of an internal thread and an external thread. The internal thread is arranged at the opening end of the cover body 5-1.

The cover body 5-1 can be directly connected to the anchor plate 3 through screw threads or indirectly connected to the anchor plate 3 through the anchor plate ring 3-1, so as to seal the anchor.
Referring to fig. 4, 5 and 6, the anchor plate 3 of the anchor capable of rapidly sealing the anchor is of a circular structure. The positioning structure is composed of an anchor plate ring 3-1 and a fixing ring 11. The anchor plate ring 3-1 is a circular plate and is integrally arranged with the same axis or fixedly connected with the outer side of the anchor sealing end of the anchor plate 3. The periphery of the anchor plate ring 3-1 is uniformly provided with a plurality of convex blocks 10. The fixing ring 11 is a ring-shaped structure with an n-shaped section and comprises an inner ring, a central ring and an outer ring. The inner side ring is of a circular ring plate-shaped structure with the inner diameter the same as the diameter of the opening end of the cover body 5-1, and is coaxially and integrally arranged with the opening end of the cover body 5-1; the outside diameter of the inside ring is equal to or slightly larger than the diameter of the anchor plate ring 3-1. The shape and the structure of the outer side ring are the same as those of the inner side ring, and the outer side ring is positioned on one side of the inner side ring, which is opposite to the cover body 5-1, and is coaxially arranged with the inner side ring; the inner ring is spaced from the outer ring by a distance equal to or slightly greater than the thickness of the anchor plate ring 3-1. The center ring is of a circular ring cylindrical structure with the inner diameter being the same as the outer diameter of the inner side ring, is integrally connected to the outer sides of the inner side ring and the outer side ring and just completely wraps the inner side ring and the outer side ring. The inner side ring, the central ring and the outer side ring of the integrated structure form an annular groove 13, the diameter of the annular groove 13 is equal to or slightly larger than that of the anchor plate ring 3-1, and the width of the annular groove 13 is equal to or slightly larger than the thickness of the anchor plate ring 3-1.
