The following explains key terms appearing in the present application.
The application provides an all-round reflection of light split pin of ship anchor formula, mainly used prevents droing of pole tower bolt among the electric power industry, including the round pin body 1.
Fig. 1 is a schematic structural view of a cotter pin in a non-use state according to an embodiment of the present application. As shown in fig. 1, a pin head 2 is disposed at an upper end of the pin body 1, and the pin head includes a plurality of pin head pieces 3, in this embodiment, the number of the pin head pieces 3 is 2, and in other embodiments, the number of the pin head pieces may also be selected from other values.
The bottoms of the pin head pieces 3 are respectively and integrally formed with the pin body 1, in the embodiment, the pin head pieces 3 are double-layer 304 stainless steel sheets, the pin head pieces 3 have certain toughness, and the pin head pieces 3 can be bent relative to the pin body 1.
Fig. 2 is a schematic structural view of a cotter pin in use in one embodiment of the present application. In actual operation, the pin head piece 3 is bent and separated from the pin body 1 by using pliers or other tools, as shown in fig. 2. The bent pin head piece 3 is bent to the side away from the pin body 1.
The bottom of the pin body 1 is provided with a pin leg, the pin leg comprises a plurality of pin leg supporting pieces 4, each supporting piece is composed of 4 light reflecting sheets with the same shape, and each light reflecting sheet is spaced by 90 degrees. The pin leg supporting pieces 4 are uniformly distributed by taking the pin body 1 as a center, the upper ends of the pin leg supporting pieces 4 are respectively and integrally formed with the pin body 1, and the bending radian of the pin leg supporting pieces 4 is adapted to the circumferential surface of the bolt 5.
The pin leg supporting pieces 4 are formed in an arc shape, and the ends of the pin leg supporting pieces 4 are bent toward the pin body 1, and in this embodiment, the number of the pin leg supporting pieces 4 is 4.
Fig. 3 is a schematic view of a cotter pin and a bolt in one embodiment of the present application. As shown in fig. 3, the bolt 5 is sectioned, the bolt 5 is provided with a through hole, the pin body 1 is inserted into the through hole, when the cotter pin is used in cooperation with the bolt, the bent pin head piece 3 is bent toward the bolt surface, the pin leg support piece 4 is attached to the circumferential surface of the bolt 5, and the bent pin leg support piece 4 is in a ship anchor type structure. The distance from the bottom end of the pin head piece 3 to the pin leg supporting piece 4 is smaller than the diameter of the bolt 5, so that the bending degree of the pin head piece 3 can be ensured, and the pin head piece 3 can be firmly clamped with the bolt 5.
The pin leg supporting sheet 4 is coated with a reflective coating, in the embodiment, the reflective coating is made of polymer reflective polyurethane plastic, the reflective coating material is not faded or darkened by the environment, and the omnibearing reflective material has the advantages of simple processing procedure, convenient operation, long service life and no pollution to the environment.
In this embodiment, the surface of reflective coating is many arriss wide angle design, and reflective coating can 360 degrees direction reflection light, can be convenient for patrol the line personnel and can both see the split pin rapidly under the tower or slightly remote various positions, judge whether the shaft tower bolt and nut are connected reliably.
In this embodiment, in order to facilitate the inspector to observe the cotter and improve the fastening of the cotter to the bolt, assuming that the length of the pin head piece 3 is D, the length of the pin body 1 is L1, and the length of the pin leg supporting piece 4 is L2, when D > 12, the relationship among the lengths of the pin body 1, the pin head piece 3, and the pin leg supporting piece 4 is L1+ L2 equals 4D; when D is less than or equal to 12, the length relationship among the pin body 1, the pin head piece 3 and the pin leg supporting piece 4 is L1+ L2-4D + 10. The above length units are all mm.
The split pin with the length relation can be conveniently and rapidly seen by a patrolman at various positions below the tower or slightly far away, and meanwhile, the connection tightness of the split pin and the bolt can be improved.
