Abstract
The utility model discloses a spring-clip type anti-loosening nut which comprise a spring clip (2) and a nut (1), wherein an ear piece (3) is arranged on the spring clip (2), a lug boss (4) is arranged on the nut (1), and the lug boss (4) is connected with the ear piece (3). The utility model can effectively reduce the alternating relay acted on a bolt and the nut and the shearing force suffered by the bolt, prolong the service life and the reliably of a fastener and satisfy the long-term working requirements at special positions in harsh environments, such as high temperature, high pressure, strong vibration, and the like. In the utility model, when the bolt is screwed in, the distance between spring plates at the upper edge and the lower edge of the spring clip is shortened to generate radial and axial tension, therefore, the bolt has the anti-loosening function under the action of the radial and axial tension. The utility model is especially suitable for uneven slope connection due to the U-shaped deformation effect.
Description
Technical field
The utility model relates to a kind of lock nut, particularly relates to a kind of spring clip type lock nut.
Background technique
In Aeronautics and Astronautics, automobile and other industries; the connection of some special shape component is arranged; as being connected or plane and being connected of inclined-plane etc. as inclined-plane and plane; and connect also very severe of the common working environment of the used fastening piece (as screw, screw bolt and nut etc.) in inclined-plane and plane; as in high temperature, high pressure and strong vibration, working; in this working environment; use common screw-nut to connect; through regular meeting screw taking place fractures or breaks because of tired; the inefficacy that causes component to connect, reliability decrease.Particularly in some significant points, as above-mentioned situation taking place, also serious accident can take place.
Summary of the invention
The purpose of this utility model is, a kind of spring clip type lock nut is provided.It can effectively reduce the alternation relay that is subjected on the screw and nut, also can effectively reduce the shearing force that is subjected on the screw, can prolong the working life and the reliability of fastening piece, satisfy the requirement of specific position long-term work in rugged environment such as high temperature, high pressure and strong vibration.
The technical solution of the utility model: a kind of spring clip type lock nut, comprise spring clip and nut, spring clip is provided with auricle, and nut is provided with boss, and boss is connected with auricle.
In the above-mentioned spring clip type lock nut, described spring clip is the U-shaped structure, and the bending part of U-shaped structure is provided with the reinforcement flange, is respectively equipped with auricle and shell fragment on two limits of U-shaped structure, and shell fragment is provided with tapped hole, and the tapped hole place is provided with and adds hassock.
In the aforementioned spring clip type lock nut, described spring clip is made with 60Si2Mn or 17-7PH material.
In the aforementioned spring clip type lock nut, described nut is a self-locking nut.
In the aforementioned spring clip type lock nut, described nut is made with A286 or 40CrNiMoA material.
Compared with prior art, it can effectively reduce the alternation relay that is subjected on the screw and nut the utility model, also can effectively reduce the shearing force that is subjected on the screw, can prolong the working life and the reliability of fastening piece, satisfy the requirement of specific position long-term work in rugged environment such as high temperature, high pressure and strong vibration.The utility model is in the process that screw screws in, and the top of spring clip dwindles with following shell fragment distance, produces radial and axial pulling force, makes screw have locking functions under the effect of radial and axial pulling force.Because being more suitable for being used for irregular inclined-plane, the metamorphosis of U-shaped, the utility model connect.For more effective raising reliability, the used nut of the utility model adopts self-locking nut.The utility model also can be worked under high temperature and strong vibration environment, and the fatigability that can slow down screw fractures.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of spring clip;
Fig. 3 is the nut structure schematic representation;
Fig. 4 is application example figure of the present utility model.
Being labeled as in the accompanying drawing: the 1-nut, the 2-spring clip, the 3-auricle, the 4-boss, 5-strengthens flange, and 6-adds hassock, 7-tapped hole, 8-shell fragment, the oblique link of 9-, 10-sheet material, 11-screw or bolt.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment.Fig. 1 is a schematic representation of the present utility model, comprises spring clip 2 and nut 1, and spring clip is made with 60Si2Mn or 17-7PH, and nut is made with A286 or 40CrNiMoA material.Spring clip 2 is provided with auricle 3, and nut 1 is provided with boss 4, and boss 4 is connected with auricle 3.Spring clip 2 as shown in Figure 2, spring clip 2 is the U-shaped structure, the bending part of U-shaped structure is provided with strengthens flange 5, is respectively equipped with auricle 3 and shell fragment 8 on two limits of U-shaped structure, shell fragment 8 is provided with tapped hole 7, tapped hole 7 places are provided with and add hassock 6.Fig. 3 is the schematic representation of nut, and nut 1 is provided with boss 4, and nut 1 is a self-locking nut.
Fig. 4 is an application example of the present utility model, as seen from Figure 4, this example is the example that sheet material 10 is connected with an oblique link 9, and screw 11 is spun in the nut 1 of the present utility model, and screw 11 passes the tapped hole or the through hole that screw in oblique link 9 in the tapped hole 7 on the shell fragment 8 again and fixes through nut.After adopting the utility model, the perpendicularity of screw can be guaranteed, and reliable the connection can be guaranteed.In the process that screw screws in, the top of spring clip 2 dwindles with following shell fragment distance, produces radial and axial pulling force, makes screw have locking functions under the effect of radial and axial pulling force.Because being more suitable for being used for irregular inclined-plane, the metamorphosis of U-shaped, the utility model connect.Owing to adopted technique scheme, the utility model also can be worked under high temperature and strong vibration environment, and the fatigability that can slow down screw fractures.
