Detailed Description
The technical solution of the present invention is further explained by the accompanying drawings and examples.
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
As shown in the figure, a ears anticreep type locator for contact net, includes pipy body 1, and the both ends of body 1 are linear structure, and its middle part is the bellied smooth structure that makes progress, and the structure of body 1 sets up the effectual uncertainty effort that has cushioned and bring. Because the train runs quickly, the contact line can twist left and right and float up and down. The middle part of the body 1 is upwards raised, so that the up-and-down floating acting force is effectively buffered, and the up-and-down acting force of the front end positioning support of the positioner is slowed down. And, to strengthening the bearing strength through the pipe of establishing of outside cover among the prior art to can bear power from top to bottom. The utility model discloses a body structure is little protruding through the arc that sets up, guarantees elasticity and intensity simultaneously.
One side of the body 1 is provided with a vertical downward connecting part 2 connected with a contact line, the other side of the body is provided with a positioning part 3 positioned on the same straight line, the connecting part 2 is used for realizing the connection of the suspension assembly, and the positioning part 3 is used for realizing the connection of the positioner and the positioning support.
The positioning part 3 comprises a vertical positioning plate 4 positioned on the central line of the body 1 and a hanging lug 5 vertically arranged on the upper side and the lower side of the vertical positioning plate 4, and the hanging lug 5 is used for being connected with a positioning support. The locating plate 4 is provided with a connecting hole 11 for fixing an electric connecting wire, the position of the locating plate is reasonable to set, the structure is stable, and quick installation is realized.
