A kind of screw retention locking plate provided by the utility model embodiment, comprising: locking plate ontology 1, locking plate ontology 1
One end is equipped with for the perforative through-hole 11 of bolt 2, and the other end is equipped with crotch 12, which is used for and is equipped with the zero of the bolt 2
Component is connected with each other, and the side that locking plate ontology 1 is equipped with through-hole 11 is equipped with flanging 13, wherein crotch 12 and flanging 13 preferably with lock
Piece ontology 1 be integrally formed, the flanging 13 when locking plate is not installed and plane locating for locking plate ontology 1 have lesser angle so as to
In the installation of bolt 2, bolt 2 can turn up flanging 13 after tightening mutually to be close to the nut side wall of bolt 2.Pass through the bolt
It is locking that locking effect can be effectively played with locking plate, even if the case where along 2 axial float of bolt occur in components, will not influence
The anti-loosing effect of locking plate.
Specifically the screw retention is applied when on scissor aerial work platform with locking plate, bolt 2 sequentially passes through this
After locking plate, clamping plate 3 and scissor assembly fixing end 4, make the crotch 12 and clamping plate 3 and scissor assembly fixing end 4 on locking plate ontology 1
Side wall develop after, flanging 13 is folded up and is close to the nut side wall of bolt 2, locking plate is rotated around 2 axis of bolt at this time
Freedom degree is limited, so that position-limiting action of the nut of bolt 2 by flanging 13, that is, play anti-loose effect.
In addition, one can also be arranged on the cover 3 for accommodating the limit hole 5 of crotch 12, in conjunction with the limitation of flanging 13, lock
The position of piece is defined, as long as the position of locking plate is defined, will not also be generated naturally with the bolt 2 that its flanging 13 is mutually close to
The possibility of rotation plays the locking effect of bolt 2.
It is not limited, is also applicable in other by above-mentioned application apparatus with locking plate it should be noted that above-mentioned bolt 2 is locking
In equipment, it can specifically be selected according to the actual situation.
Further, the width of locking plate ontology 1 is from one end of through-hole 11 is equipped with to the tapered at one end for being equipped with crotch 12.Pass through
The integrated molding of crotch 12 is convenient in the setting of converging transition, and when using locking plate, crotch 12 can be in same flat with locking plate ontology 1
In face, the length of crotch 12 can be bent as needed, i.e. the spacing of crotch 12 and through-hole 11 can be adjusted according to the actual situation
It is whole, improve the scope of application of locking plate.
Specifically, the bending direction of crotch 12 and the bending direction of flanging 13 are opposite.That is nut of the flanging 13 towards bolt 2
Direction bending, crotch 12 should bend towards the direction of 2 end of bolt so that after bending flanging 13 and crotch 12 extending direction
It is parallel to each other with the axis of bolt 2.
Specifically, locking plate ontology 1 is equipped with multiple flangings 13.Wherein the avris of each flanging 13 and nut is mutually adjacent to,
Such as nut, when being hexagon, the side wall of each flanging 13 and hexagonal (hexagon)nut, which corresponds, to be mutually adjacent to.Improve the limit of flanging 13
Safety.
Specifically, flanging 13 there are two being set on locking plate ontology 1, center of two flangings 13 between through-hole 11 and crotch 12
Line is symmetrical arranged.Through two flangings 13 under the premise of playing limit safety, installation effectiveness can be improved.
Further, re-entrant angle 14 is equipped between the side of flanging 13 and the side of locking plate ontology 1.By re-entrant angle 14 convenient for peace
Bolt 2 is installed later to bend flanging 13.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.
A kind of screw retention provided by the utility model is described in detail with locking plate above.It is used herein
Specific case is expounded the principles of the present invention and embodiment, and the explanation of above example is only intended to help to manage
Solve the method and its core concept of the utility model.It should be pointed out that for those skilled in the art, not
Under the premise of being detached from the utility model principle, several improvements and modifications can be made to this utility model, these improve and repair
Decorations are also fallen into the protection scope of the utility model claims.
