Abstract
The utility model relates to the technical field of fasteners, in particular to a loosening-preventing nut provided with a flange. The nut comprises a hexangular nut body, wherein an inner thread hole is arranged in the hexangular nut body, the end face of the hexangular nut body where a bolt is screwed is provided with the flange, the flange is provided with a through hole in the same size and shape as the inner thread hole, the other end face of the hexangular nut body is provided with a locking piece protruding inward, the locking piece is an elastic metal piece, the outer edge of the locking piece is fixed to the hexangular nut body, and the inner edge of the locking piece protrudes out of the inner thread hole of the hexangular nut body. The locking piece can be deformed and clamped into a thread groove of the bolt during the process that the bolt is screwed in the nut, and can abut against the inner side of the thread groove in the bolt to achieve locking. Therefore, during the screwing process of the nut, automatic deformation forms locking, the loosening-preventing effects are achieved, and operation is simple and convenient. Meanwhile, the nut and a fastened element are in flange contact, the locking area is large, and the locking is reliable.
Description
Technical field
The utility model relates to technical field of fastening, is specifically related to a kind of lock nut with flange plate.
Background technique
Nut is exactly nut, the part that is used for playing the role of fastening together with bolt or screw rod are screwed in, and it is widely used in every field as a kind of fastening piece commonly used.Existing plain nut does not have to loosen and takes off structure, in the time of on the object of often mobile or vibrations, and long-time the use, nut is easy to loose or dislocation from the bolt, causes product quality problem, security incident and economic loss will occur when serious.For a change have the defective that plain nut exists now, people's door adds locking member on the basis of plain nut, but it is complex structure often, and its locking member can not auto lock, after nut and bolt tightening, must also to the locking member on nut be applied certain active force by extra operation, locking member is deformed, and then make nut check on bolt, operation inconvenience.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of tep reel lock nut with flange plate and self-locking function, have simple in structure, the advantage of easy to operate and reliable lock.
For achieving the above object, the utility model provides following technological scheme: a kind of tep reel lock nut, include the hexagon nut body, the hexagon nut body is provided with interior threaded hole, it is characterized in that: described hexagon nut body is screwed into bolt one end end face and is provided with flange plate, flange plate is provided with the through hole identical with the interior threaded hole size shape, hexagon nut body the other end end face is provided with outstanding to the inside locking plate, described locking plate is elastic sheet metal, the locking plate outside is fixed on the hexagon nut body, the interior threaded hole of the outstanding hexagon nut body of locking plate inner edge.
By adopting technique scheme, flange plate has the nut check face of increase, increases locking torque, makes locking more reliable, and locking plate be out of shape in being screwed into the bolt process at nut and snaps in the thread groove of bolt simultaneously, and is against in thread groove on bolt and realizes locking; In the nut screwing clamping process, auto Deformation produces locking, reaches anti-loosing effect, and is simple to operation like this.
The utility model further is set to: described locking plate is extended internally by annular metal sheet internal ring wall and forms, and annular metal sheet internal ring wall is formed with two locking plates that are oppositely arranged.
Further be set to: described hexagon nut body is provided with the shell fragment that compresses described locking plate again.
Further be set to: described shell fragment one end is fixed on the hexagon nut body again, and the other end oppositely inwardly turns down described locking plate is pressed on hexagon nut body end face.
Further be set to: turnover place of described shell fragment is circular-arc setting again.
Further be set to: described flange plate is connected an end end face with the hexagon nut body be the conical surface setting, and flange plate the other end end face is the locking face that is provided with spiral oblique tooth-shaped ridge design again.
By adopting technique scheme, nut has the reliable lock advantage.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment tep reel lock nut;
