Abstract
The utility model discloses a self-adapting type pinch cock self-locking nut, comprising an S type pinch cock (1) and a self-locking nut body (2), wherein, a clamp-fixing hole (3), a transitional hole (4) and a guide-positioning hole (5) are formed on the S type pinch cock (1); the clamp-fixing hole (3) is used for fixing the self-locking nut body (2) in a clamping manner; the transitional hole (4) is used for mounting a bolt; and the guide-positioning hole (5) is used for guiding positioning; and the self-locking nut body (2) is arranged in the clamp-fixing hole (3) and is connected with the transitional hole (4). The pinch cock self-locking nut is characterized in that a U-shaped groove (6) which circles the guide-positioning hole (5) is further formed on the S-shaped pinch cock (1). The pinch cock self-locking nut has the advantages of not only convenient use, but also reliable operation, and high stability.
Description
Technical field
The utility model relates to a kind of fastening piece, and especially a kind of self-adapting type spring clip self-locking nut belongs to technical field of fastening.
Background technique
At present, the compound material utilization is very wide, and in the connection of composite material, because during the machining screw of some material own, the intensity of its screw thread and precision all can't guarantee, especially in being connected between composite board and sheet material, the intensity of screw thread can't satisfy the tired and vibration requirement in the using process especially.So, a kind of simple and easy and efficiently fastening connection piece satisfied such requirement, the design feature that S type spring clip is optimized with self has solved the connectivity problem between the composite board well.On existing spring clip self-locking nut, follow the clamp face of S type spring clip in use and move owing to being located at guide-localization hole on its S type spring clip, usually make the center of the misalignment self-locking nut in its guide-localization hole, bolt is not easy on the self-locking nut very much, and therefore existing spring clip self-locking nut is still not ideal in use.
The model utility content:
The purpose of this utility model is: the center that a kind of center that can keep the guide-localization hole in use substantially and self-locking nut be provided is on same center line and the reliable self-adapting type spring clip of clamping self-locking nut, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises S type spring clip and self-locking nut body, on S type spring clip, be provided with the clamping hole that fixes the self-locking nut body and be used for the transitional pore of assembling bolt and be used for the guide-localization hole of guide-localization, the self-locking nut body is positioned in the clamping hole and with transitional pore and accepts mutually, also is provided with the U-groove bevel around the guide-localization hole on S type spring clip.
The center that is located at clamping hole, transitional pore and guide-localization hole on the S type spring clip is all on same axis, and the center in the semi-circle center of U-groove bevel and three holes is not on same axis.
The self-locking nut body is square nut or is regular hexagon nut or regular polygon nut that the hole shape of clamping hole is identical with the profile of self-locking nut.
Transitional pore and guide-localization hole are circular hole, and the diameter in two holes can make bolt be easy to assembling all greater than the bolt external diameter that is used with the self-locking nut body like this.
Be coated with MoS on the surface of self-locking nut body
2The dry film self-lubricating layer.
Owing to adopted technique scheme, the utility model has U-groove bevel on S type spring clip, when S type spring clip in when work, S type spring clip is produced the elastic force that needs answer by resiliently deformable, when being clamped and connected sheet material, sheet material is drilled with through hole in advance, and in-flanges has been done in the guide-localization hole of spring clip, so spring clip can fix in the pre-hole of sheet material when inserting connected sheet material again, thereby perform the effect of location.And the elastic deformation force of spring clip self-locking nut can clamp the sheet material of connection securely, and the self-locking nut body has certain gap of moving about in the clamping hole of spring clip, plays certain Self-centering Action, make when assembling bolt, bolt easily is screwed into easily, has made things convenient for assembling to use.The spring clip self-locking nut also can produce certain self-lock force at work, causes the distortion of nut self when bolt is screwed into, and makes nut encase bolt firmly, thereby in vibration, has increased the stability and the reliability of fastening piece self in the environment of fatigability.Because the effect of U-groove bevel, during use, the central position in its guide-localization hole can not be affected substantially, even variation has taken place in the central position in guide-localization hole, at dress during bolt and since the guide-localization hole be provided in a side of U-groove bevel around the U-shaped plate on, this U-shaped plate has certain elasticity, thereby can regulate the position in guide-localization hole adaptively according to the needs that use, bolt is easier to be connected with self-locking nut thereby make; Be coated with MoS2 (molybdenum disulfide) dry film selflubricating agent in the self-locking nut surface, make to have self-lubricating property when bolt is screwed into.Therefore, the utility model is compared with prior art, and is not only easy to use, and working stability is reliable.

Embodiment
Embodiment of the present utility model: produce S type spring clip 1 and self-locking nut body 2 earlier, on S type spring clip 1, produce the clamping hole 3 that fixes self-locking nut body 2 simultaneously and be used for the transitional pore 4 of assembling bolt and be used for the guide-localization hole 5 of guide-localization, during making, on S type spring clip 1, produce a U-groove bevel 6 more simultaneously around guide-localization hole 5, and make the clamping hole 3 that is located on the S type spring clip 1, the center in transitional pore 4 and guide-localization hole 5 is all on same axis, and make the center in the semi-circle center of U-groove bevel 6 and other three hole can be not on same axis, transitional pore 4 and guide-localization hole 5 all are made into circular hole, and the diameter that makes this two hole is convenient to bolts assemblies so all greater than the bolt external diameter that is used with self-locking nut body 2; Self-locking nut body 2 can be made as square nut or be regular hexagon nut or regular polygon nut, and is made into the hole shape of clamping hole 3 identical with the profile of self-locking nut 2; After self-locking nut body 2 is made moulding, on the surface of self-locking nut body 2, be coated with and be covered with MoS
2The dry film self-lubricating layer; At last self-locking nut body 2 is positioned in the clamping hole 3 and accepts mutually with transitional pore 4.
When using the utility model, only needing S type spring clip 1 is fixed on connected connecting plate (or supporting element) 7 can be by being connected with bolt that self-locking nut body 2 matches.
