Abstract
The utility model discloses an antiskid bolt for internal and external purposes, which belongs to a fastening connecting part and mainly solves the problem that the nut of the existing bolt easily slides to cause unavailable disassembly. The antiskid bolt for internal and external purposes comprises a screw and a nut and is characterized by also being provided with a threaded insert used for screwing out the nut. The threaded insert has a hollow structure with openings at two ends, and the inner wall of the threaded insert is provided with an outer embedded structure that can be totally embedded with the outer wall of the nut. The outer wall of the nut is provided with an indented structure and a projecting structure, which are arranged in a cross manner, and the outer embedded structure is provided with a projecting structure and an indented structure that correspond to the indented structure and the projecting structure on the outer wall of the nut. The antiskid bolt is ingenious in design, simple in structure and convenience in use, can effectively solve the problem that the nut is prone to slide, and has high practical value.
Description
Technical field
The utility model relates to a kind of bolt, specifically, relates to a kind of inside and outside dual-purpose anti-skidding bolt.
Background technique
Bolt is a kind of very common connected element, is mainly used in fastening between the various parts mechanically.Existing bolt all is made up of and complete use screw rod and nut, and is fastening by the mutual interlock realization of screw thread between screw rod and the nut, when needing dismounting, also is to realize dismounting by the derotation nut.There is a unavoidable problem in the Placement of existing this screw rod and nut: in case the nut outer wall is polished, spanner can't be dismantled nut, and then causing the fastening relation between screw rod and the nut to untie, the parts that need so to dismantle can't be realized dismounting.This defective that prior art exists is worth at some may bring very tremendous loss on the expensive equipment, therefore, solve this defective and just seem very important.
The model utility content
The purpose of this utility model is to provide a kind of inside and outside dual-purpose anti-skidding bolt, overcomes the problem that prior art exists, and guarantees the detachability between screw rod and the nut, and the situation of avoiding dismantling occurs.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of inside and outside dual-purpose anti-skidding bolt comprises screw rod and nut, and the swivel nut that is used to screw out nut, and this swivel nut is the hollow structure of both ends open, its inwall be provided with can with nut outer wall chimeric outer embedded structure fully.
Say further, offer concave inward structure arranged in a crossed manner and outer male structure on the described nut outer wall, described outer embedded structure then be with the nut outer wall on concave inward structure and outer male structure outer male structure and concave inward structure accordingly.Specifically, described concave inward structure is the cuboid groove, and outer male structure is the cuboid projection.
Described swivel nut is the cylindric of both ends open.In order to prevent that swivel nut can't be placed on the nut, can also the sidewall of this swivel nut be improved, i.e. described swivel nut sidewall opening.
Say further that again the top end face of described screw rod offers groove, outer wall is provided with concave inward structure and the evagination structure composition that is used to screw out screw rod, and the arrangement mode of described concave inward structure and outer male structure is vertical interleaved mode.
Compared with prior art, the utlity model has following beneficial effect:
1. design ingenious, simple in structure, easy to use.
2. the utility model improves respectively on nut and screw rod, by increasing the dismounting that a swivel nut realizes from the outside nut; Then offer a groove at the screw rod end face, and on outer side wall, be provided with embedded structure, in order to realize the back-out of screw rod, soon extracting tool inserts and realizes dismantling screw internally in this groove, inside and outside dual-purpose, complement each other, solved nut effectively and skidded and cause the problem that can't dismantle.
3. the utility model has solved the problem that prior art exists effectively, has guaranteed the smooth dismounting of nut or screw rod, and the use value of bolt is improved greatly.
4. the utility model both can be used for the dismounting of bolt, can be used for the fastening of bolt equally conversely, was a design model double-duty, had opened up another beginning of bolton mode, had and important industry technology design sense.
Description of drawings
Fig. 1 is the user mode schematic representation of screw rod, nut and swivel nut in the utility model.
Fig. 2 is the structural representation of a kind of swivel nut in the utility model.
Fig. 3 is the structural representation of another kind of swivel nut in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As Fig. 1～shown in Figure 3, a kind of inside and outside dual-purpose anti-skidding bolt comprises screw rod 1 and nut 2, and with nut 2 matching used swivel nuts 3, this swivel nut 3 is the cylindrical of both ends open, and its inside is hollow structure, inwall be provided with can with the complete chimeric outer embedded structure of nut 2 outer walls; And also offering groove 6 at the top of screw rod 1 end face, its outer side wall is provided with concave inward structure 4 and the outer male structure 5 that is used to screw out screw rod 1.
Specifically, offer concave inward structure arranged in a crossed manner 4 and outer male structure 5 on described nut 2 outer walls, described outer embedded structure then be with nut 2 outer walls on concave inward structure 4 and outer male structure 5 corresponding outer male structure 5 and concave inward structures 4.In the present embodiment, described concave inward structure 4 is the cuboid groove, and outer male structure 5 is the cuboid projection, and still, the concave inward structure 4 in the utility model, the concrete shape of outer male structure 5 can change arbitrarily, as long as both can be chimeric mutually.For the chimeric convenience of concave inward structure 4 with outer male structure 5, take into account chimeric degree simultaneously, both arrangement modes are typically chosen in vertical cross arrangement,
In order to prevent that swivel nut 3 can't be placed on the nut 2, can also the sidewall of this swivel nut be improved a sidewall opening of promptly described swivel nut 3.
According to the foregoing description, just can realize the utility model well.Protection domain of the present utility model includes but not limited to the foregoing description.
