Abstract
A lock nut belongs to a fastener and comprises a nut body and a circular truncated cone body connected with the left end surface of the nut body, wherein the nut body and the circular truncated cone body are provided with inner screw threads, the outer conical surface of the circular truncated cone body is provided with a plurality of open grooves communicated with the inner screw threads, the lock nut further comprises a cylindrical body sleeved on the circular truncated cone body, an inner hole of the cylindrical body is provided with a conical surface matched with the outer conical surface of the circular truncated cone body, an annular groove is arranged at the right end of the circular truncated cone body positioned on the outer conical surface, an annular boss is arranged at the right end of the inner hole of the cylindrical body, and the annular boss is clamped into the annular groove. The lock nut provided by the utility model has a better loosening prevention function, and a conical hole does not need to be pre-arranged in a locked part, so that the lock nut can be used by a person conveniently.
Description
Technical field:
The utility model relates to a kind of fastening piece, specifically is a kind of locking nut.
Background technique:
Common and the bolt of nut, screw fit is used the effect that connects fastening component of playing, there is at present a kind of locking nut to comprise nut body and the Rotary-table that is integrated with nut body, nut body and Rotary-table are provided with the internal thread that cooperates with bolt, the perisporium of Rotary-table is provided with a plurality of opening slots that communicate with internal thread, when using this locking nut to cooperate with bolt to lock component, must set in advance the cone shape hole that matches with the perisporium of Rotary-table on the locking nut on the component, when the Rotary-table on the locking nut partly is tightened onto in the cone shape hole, Rotary-table on the locking nut can produce resiliently deformable under the effect of cone shape hole, thereby pack tightly bolt and prevent the loosening of locking nut, although this locking nut has good locking functions, but owing to must set in advance the cone shape hole that matches with the male cone (strobilus masculinus) of Rotary-table on the locking nut on the component, therefore, this locking nut is cumbersome in use, and versatility is relatively poor.
The model utility content:
The technical problems to be solved in the utility model is, provides a kind of and not only has preferably locking functions, and be spendable locking nut but also do not need at the component that are locked cone shape hole to be set.
Technical solution of the present utility model is, provide a kind of locking nut with following structure: comprise nut body and be connected to Rotary-table on the nut body left side, nut body and Rotary-table are provided with internal thread, the male cone (strobilus masculinus) of Rotary-table is provided with a plurality of opening slots that communicate with internal thread, wherein, also comprise the cylindrical body that is enclosed within on the Rotary-table, the endoporus of cylindrical body is provided with the conical surface that matches with the male cone (strobilus masculinus) of Rotary-table, the right-hand member that is positioned at male cone (strobilus masculinus) on the Rotary-table is provided with annular groove, the endoporus right-hand member of cylindrical body is provided with annular boss, and annular boss is stuck in the annular groove.
After adopting above structure, compared with prior art, the utility model locking nut has the following advantages: owing to also comprise the cylindrical body that is enclosed within on the Rotary-table, the endoporus of cylindrical body is provided with the conical surface that matches with the male cone (strobilus masculinus) of Rotary-table, therefore, the utility model locking nut is cooperating with bolt when locking component, end with Rotary-table is screwed into first on the bolt, after the locking, Rotary-table can produce resiliently deformable under the effect of the conical surface on the cylindrical body, thereby pack tightly at bolt and prevent the loosening of the utility model locking nut, simultaneously again owing to have cylindrical body, cylindrical body is enclosed within on the Rotary-table, is cooperating with bolt when locking component, end with Rotary-table is screwed into first on the bolt, adopted the end face of cylindrical body to be pressed on the component, therefore, the utility model locking nut in use, need to not set in advance cone shape hole at component, make things convenient for people's use.
Description of drawings:
Fig. 1 is that the master of the utility model locking nut looks the sectional structure schematic representation;
Fig. 2 is the perspective view after the utility model locking nut removes cylindrical body.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model locking nut is described further:
As depicted in figs. 1 and 2, in this embodiment, the utility model locking nut comprises nut body 1, be connected to the Rotary-table 5 on nut body 1 left side and be enclosed within cylindrical body 7 on the Rotary-table 5, nut body 1 and Rotary-table 5 are provided with internal thread 2, the male cone (strobilus masculinus) 9 of Rotary-table 5 is provided with four opening slots 6 that communicate with internal thread 2, the endoporus of cylindrical body 7 is provided with the conical surface 8 that matches with the male cone (strobilus masculinus) 9 of Rotary-table 5, the right-hand member that is positioned at male cone (strobilus masculinus) 9 on the Rotary-table 5 is provided with annular groove 3, the endoporus right-hand member of cylindrical body 7 is provided with annular boss 4, and annular boss 4 is stuck in the annular groove 3.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
