Abstract
The utility model discloses a socket -clevis eye for power transmission line, including link plate main part (1) and ball -eye (2), set up a bowl headstock (3) in link plate main part (1), be provided with bowl first connecting portion (4) in the bowl headstock (3), bowl first connecting portion (4) surface is arc and bowl headstock (3) internal surface spherical hinge joint, bowl first connecting portion (4) internal surface is ball socket form and ball -eye (2) phase -match, a plurality of elastic components of link plate main part (1) outside fixed connection (5), elastic component (5) and ball -eye (2) fixed connection. The utility model discloses a set up bowl first connecting portion (4) in the middle of bowl headstock (3) and ball -eye (2), through produced effectual the reducing of pressure of cushioning effect messenger whole displacement deformation of the first connecting portion of bowl (4), the whole socket -clevis eye of effectual reduction is damaged the odds by external force.
Description
Technical field
The utility model relates to a kind of fastening means of power transmission system, is specifically related to a kind of power transmission line socket-clevis eye.
Background technology
The socket-clevis eye that in prior art, transmission pole uses generally comprises bowl head and ball-eye, and ball-eye is arranged in the bowl headstock in bowl head.The alternation effect being subject to wind-force in the air at height due to circuit produces slight vibrations, causes the friction between ball-eye and bowl headstock, makes ball-eye there is the risk got loose from bowl headstock; The area that particularly wind-force with a varied topography is bigger than normal, does not arrange protective device in bowl headstock, affects link plate life-span and line security greatly.
Chinese Patent Application No. 201420476654.7(Authorization Notice No. CN204012571U) disclose a kind of socket-clevis eye, during initial condition, two baffle plates contact with each other, the bulb of ball-eye is embedded in the process in inverted T shape groove, by the guiding of arc guide barrel, ball-eye extrudes two baffle plates, baffle plate is reclaimed in chute, smoothly the bulb of ball-eye is embedded in inverted T shape groove, after bulb embeds inverted T shape groove, spring recovers deformation, two baffle plates are made to close stymie bulb hanging ring from the slippage of inverted T shape groove notch, the socket-clevis eye of this structure can anticreep but fundamentally do not solve the friction problem of ball-eye and bowl headstock.
Utility model content
In view of this, the purpose of this utility model is for the deficiencies in the prior art, provides a kind of power transmission line socket-clevis eye, reduces frictional force between ball-eye and bowl headstock by designing buffer structure in bowl headstock.
For achieving the above object, the utility model by the following technical solutions:
A kind of power transmission line socket-clevis eye, comprise link plate main body and ball-eye, in described link plate main body, a bowl headstock is set, bowl head connecting portion is provided with in described bowl headstock, described bowl head connecting portion outer surface is arc and is connected with described bowl headstock inner surface ball pivot, described bowl head connecting portion inner surface is that ball-and-socket shape and described ball-eye match, and described link plate body exterior is fixedly connected with multiple elastic component, and described elastic component is connected with described ball-eye.
Preferably, described elastic component is disc spring.
The beneficial effects of the utility model are:
The power transmission line socket-clevis eye of the utility model design, by arranging bowl head connecting portion in the middle of bowl headstock and ball-eye, bowl head connecting portion outer surface is that arc matches with the inner surface of bowl headstock is that ball pivot is connected, when ball-eye left-right and front-back is subjected to displacement, the pressure whole Displacement-deformation being produced by the cushioning effect of bowl head connecting portion effectively reduces, thus reduce the damage odds of whole socket-clevis eye, effective prevention makes the wearing and tearing of ball-eye and bowl headstock due to External Force Acting, improves the life-span of socket-clevis eye; Arrange multiple elastic component at link plate body exterior to be in addition connected with ball-eye, also effectively can play cushioning effect when ball-eye is subjected to displacement, further increase coefficient of safety of the present utility model; In addition, elastic component selects disc spring, and the result of use of advantage in the utility model that stroke is short, load is heavy making full use of disc spring is more outstanding.
To sum up, the utility model has the advantages such as the useful life of simple, novel in design, the effective raising socket-clevis eye of structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, the utility model comprises link plate main body 1 and ball-eye 2, link plate main body 1 top is provided with the support arm 6 of band through hole (not shown), the utility model is made to be fixed on line feeding bar by support arm 6, bowl headstock 3 and bowl head connecting portion 4 are set in link plate main body 1, bowl headstock 3 inner surface is arc, bowl head connecting portion 4 outer surface is also arc and matches with bowl headstock 3 inner surface, bowl head connecting portion 4 inner surface is that ball-and-socket shape and ball-eye 2 match, link plate main body 1 external stability connects two symmetrical disc springs 5, disc spring 5 is fixedly connected with described ball-eye 2.
The utility model is provided with bowl head connecting portion 4 between bowl headstock 3 and ball-eye 2; when external force is applied on ball-eye 2; by the transitional function of bowl head connecting portion 4; external force is buffered; and connect two disc springs 5 in plate main body 1 external stability; realize further buffering effect, protect the overall structure of whole socket-clevis eye with this, effectively extend useful life of the present utility model.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, other amendments that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
Claims (2)
1. a power transmission line socket-clevis eye, comprise link plate main body (1) and ball-eye (2), in described link plate main body (1), a bowl headstock (3) is set, it is characterized in that: in described bowl headstock (3), be provided with bowl head connecting portion (4), described bowl head connecting portion (4) outer surface is arc and is connected with described bowl headstock (3) inner surface ball pivot, described bowl head connecting portion (4) inner surface is that ball-and-socket shape and described ball-eye (2) match, the external stability of described link plate main body (1) connects multiple elastic component (5), described elastic component (5) is fixedly connected with described ball-eye (2).
