Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the above.
As shown in fig. 3 and 4, a flexible rubber member includes rubber 1 and an iron-embedded member 2; before injection molding by using a rubber mold, presetting an iron burying piece 2 in the rubber 1, and integrating the rubber 1 and the iron burying piece 2 into a whole by hanging rubber; the number of the rubber 1 is several, the rubber 1 and the rubber 1 are arranged in parallel, and the adjacent rubber 1 is connected through a plurality of overlapping edges 3; the rubber 1, the iron-embedded part 2 and the lapping 3 form a flexible rubber part 5, as shown in fig. 1 and 2.
The iron burying piece 2 is provided with a plurality of small holes.
The rubber 1 completely wraps the iron-embedded part 2 to form a whole.
The iron burying pieces 2 are respectively buried in the two ends of the rubber 1.
The number of the rubber 1 is 2, the number of the bonding edges 3 is 2, the rubber 1 is divided into a first rubber and a second rubber, and the bonding edges 3 are divided into a first bonding edge and a second bonding edge; the 2 rubbers 1 are arranged in parallel, and the 2 rubbers 1 are connected through 2 overlapping edges 3.
The rubber 1 is quadrilateral, one end of the first lapping edge is connected with one corner of one side of the first rubber, and one end of the second lapping edge is connected with the other corner of the same side of the first rubber; the other end of the first lapping edge is connected with one corner of one side of the second rubber, and the other end of the second lapping edge is connected with the other corner of the same side of the second rubber, as shown in fig. 1 and 2, namely, the first rubber, the first lapping edge, the second rubber and the second lapping edge are connected end to form a closed quadrilateral.
