Abstract
The utility model relates to the technical field of locking mechanisms, and discloses a locking mechanism combining a nut and a stamping part, which comprises a stamping plate, wherein at least two fastening heads are symmetrically and fixedly arranged on the stamping plate, and threaded holes are formed in the fastening heads; the punching plate corresponding to the threaded hole is provided with an opening, and the opening is coaxial with the threaded hole; wherein, the edge of trompil is offered and is a plurality of radial strip mouths that set up with it, and the punching press board between two adjacent strip mouths forms the elastic sheet, and the elastic sheet is crooked towards the one side that keeps away from the fastening head. When the screw bolt is used, the elastic piece is gradually locked by the screw rod, so that the elastic piece is bent and deformed to generate reverse acting force, the acting force acts between the screw head and the stamping plate, the screw head and the stamping plate expand, and the screw bolt is more fastened.
Description
Technical Field
The utility model relates to the technical field of locking mechanisms, in particular to a locking mechanism combining a nut and a stamping part.
Background
Bolts are commonly used as connecting pieces, and in the using process of the bolts, elastic gaskets are commonly used for preventing the bolts from loosening, but the fastening capability of a single bolt matched with the gaskets is limited, so that a locking mechanism combining a nut and a stamping part is provided.
Disclosure of Invention
Aiming at the defects of the existing bolt fastener, the utility model provides a locking mechanism combining a nut and a stamping part, which has the advantages of high fastening strength and looseness prevention and solves the problems in the prior art.
The utility model provides the following technical scheme: the locking mechanism comprises a stamping plate, wherein at least two fastening heads are symmetrically and fixedly arranged on the stamping plate, and threaded holes are formed in the fastening heads;
the punching plate corresponding to the threaded hole is provided with an opening, and the opening is coaxial with the threaded hole;
wherein, the edge of trompil is offered and is a plurality of radial strip mouths that set up with it, and the punching press board between two adjacent strip mouths forms the elastic sheet, and the elastic sheet is crooked towards the one side that keeps away from the fastening head.
Preferably, the fastening head is cylindrical or regular hexagonal.
Preferably, the connection between the fastening head and the stamping plate is rounded.
Preferably, the anti-slip device further comprises a screw rod matched with the threaded hole, one end of the screw rod is connected with a screw head, and a plurality of anti-slip protrusions are arranged on the surface of one side of the screw head, close to the stamping plate.
Preferably, after the elastic sheet is bent and unfolded, the space enclosed by the elastic sheet forms a perforation.
Compared with the prior bolt fastener, when the bolt fastener is used, the elastic piece is gradually locked by the screw rod, so that the elastic piece is bent and deformed to generate reverse acting force, the acting force acts between the screw head and the stamping plate, the screw head and the stamping plate expand, and the bolt is more fastened.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model.
Fig. 2 is a schematic diagram of a stamping plate structure of the present utility model.
FIG. 3 is a schematic view of the structure of the elastic sheet of the present utility model after being dispersed.
In the figure: 1. a stamping plate; 2. a fastening head; 3. a threaded hole; 4. opening holes; 5. a strip-shaped opening; 6. a screw; 7. a slip preventing protrusion; 8. a screw head; 9. an elastic sheet; 10. and (5) perforating.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-3, a locking mechanism for combining a nut and a stamping part comprises a stamping plate 1, wherein at least two fastening heads 2 are symmetrically and fixedly arranged on the stamping plate 1, threaded holes 3 are formed in the fastening heads 2, the fastening heads 2 are cylindrical or regular hexagons, and the joint between the fastening heads 2 and the stamping plate 1 is in arc transition to prevent stress concentration.
As shown in fig. 2, the punching plate 1 corresponding to the threaded hole 3 is provided with an opening 4, and the opening 4 and the threaded hole 3 are coaxial;
wherein, the edge of trompil 4 has offered the strip mouth 5 that a plurality of radial settings with it, and the punching plate 1 between two adjacent strip mouths 5 forms elastic sheet 9, and elastic sheet 9 is crooked to the one side that keeps away from fastening head 2, and after elastic sheet 9 crooked expansion, the space that elastic sheet 9 encloses forms perforation 10.
As shown in fig. 3, the elastic sheet 9 is bent at the edge of the through hole 10 so that the elastic sheet 9 has a certain elasticity, and the elastic sheet 9 is compacted when the bolt is fastened.
The utility model also comprises a screw rod 6 matched with the threaded hole 3, one end of the screw rod 6 is connected with a screw head 8, and a plurality of anti-slip protrusions 7 are arranged on the surface of one side of the screw head 8, which is close to the stamping plate 1.
Specifically, in use, the screw rod 6 is inserted into the through hole 10 from the threaded hole 3 and penetrates through the member to be fastened, then the screw head 8 is rotated to screw the screw rod 6 into the threaded hole 3, the fastening head 2 compresses the elastic sheets 9 with the tightening force, and the elastic sheets 9 have opposite acting force on the surface of the stamping plate 1, so that the locking force of the bolt cannot be loosened.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
