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 stable form registration arm connection structure for contact net, including horizontal body 1 and converter 3, body 1 realizes wholly being connected with the last holding ring of oblique cantilever with being connected of converter 3. The front end of body 1 is equipped with connecting portion 2 that the symmetry set up, and connecting portion 2 are located the inboard on body 1 outer edge, and the both sides of connecting portion 2 all are equipped with the arc transition limit 6 of outside extension, and transition limit 6 has improved the bearing strength of connecting portion 2. The bottom of the connecting part 2 is slightly concave inwards, so that micro elasticity is provided for the non-directional stress of the pipe body 1, and the pipe body is not easy to deform under the stress action because of rigid connection.
Converter 3 includes that the first portion of turning to 4 that is located between connecting portion 2 and the second that is connected with first portion of turning to 5, is equipped with the through-hole that corresponds with connecting portion 2 upper hole on the first portion of turning to 4, guarantees the stable connection between first portion of turning to 4 and the connecting portion 2, realizes being connected of converter 3 and body 1 promptly. The second turning part 5 is provided with a positioning hole 7 connected with the positioning ring, and the converter 3 is connected with the positioning ring through the second turning part 5. The first steering part 4 is of a single-lug structure, and the second steering part 5 is of a drop-shaped double-lug structure. The thickness of the first steering part 4 is not larger than the distance between the connecting parts 2, and the first steering part 4 can rotate between the connecting parts 2, so that part of the acting force caused by violent non-directional vibration is quickly released.
The second turning part 5 is vertically arranged at two sides of the bottom of the first turning part 4, and the structure of the second turning part enables the transmission of force to be turned. The outer edge of the side of the second steering part 5 is provided with a connecting rib 8 extending to the first steering part 4, so that the bearing strength of the second steering part 5 is improved. The outer diameter of the bottom of the first steering part 4 is equal to the thickness of the second steering part 5, so that the stress is transmitted to the second steering part 5 in a balanced manner, and the condition that the second steering part 5 is stressed in a concentrated manner cannot be caused. The width of the bottom of the second steering part 5 is smaller than the diameter of the positioning hole 7, and the stress of the second steering part 5 is transmitted to the positioning ring in the positioning hole 7. If the atress is too big, the second turns to portion 5 can protect the holding ring through deformation, can not cause too much parts to damage when guaranteeing whole steady operation.
