Abstract
The utility model relates to a check nut and belongs to a fastener. The check nut comprises a nut body and a circular truncated cone connected to the right end face of the nut body, wherein threaded through holes are formed on the nut body and the circular truncated cone; and a plurality of open slots communicated with the threaded through holes are formed on the outer conical surface of the circular truncated cone. The check nut also comprises a cylinder sleeved on the circular truncated cone, wherein a conical surface matched with the outer conical surface of the circular truncated cone is formed on the inner hole of the cylinder; and the left part of the cylinder is in threaded connection with the circular truncated cone. The check nut has a good locking function; a conical hole does not need to be formed on a locked part in advance; the check nut is convenient to use.
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 is connected to Rotary-table on the nut body, nut body and Rotary-table are provided with the tapped through hole that cooperates with bolt, the male cone (strobilus masculinus) of Rotary-table is provided with a plurality of opening slots that communicate with tapped through hole, when using this locking nut to cooperate with bolt to lock component, 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, 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 the well locking function of moving back, 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 right side, nut body and Rotary-table are provided with tapped through hole, the male cone (strobilus masculinus) of Rotary-table is provided with a plurality of opening slots that communicate with tapped through hole, 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, and the cylindrical body left part is threaded with Rotary-table.
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, the cylindrical body left part is threaded with Rotary-table, therefore, the utility model locking nut is cooperating with bolt when locking component, the left end of nut body screws in first bolt, behind the locking component, cylindrical body is being tightened on the Rotary-table, at this moment 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, from above using process as can be known, the utility model locking nut is cooperating with bolt when locking component, the left end of nut body screws in first bolt, the left end that is nut body is locking face, not that to adopt the end with Rotary-table be locking face, 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 of the utility model locking nut.
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 2, be connected to the Rotary-table 3 on nut body 2 right sides and be enclosed within cylindrical body 6 on the Rotary-table 3, nut body 2 and Rotary-table 3 are provided with tapped through hole 1, the male cone (strobilus masculinus) 8 of Rotary-table 3 is provided with four opening slots 5 that communicate with tapped through hole 1, the endoporus of cylindrical body 6 is provided with the conical surface 7 that matches with the male cone (strobilus masculinus) 8 of Rotary-table 3, cylindrical body 6 left parts are threaded with Rotary-table 3, and the periphery of cylindrical body 6 is provided with two parallel slots 4 that block for spanner.
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.
