Abstract
The utility model relates to a fastening part with inner threads and outer threads, which relates to the technical field of fastening components, and solves the technical problem that a current multi-layer structure article is complicated in connecting and fixing process. The fastening part comprises a bolt-shaped body, and is characterized in that the outer threads are arranged on the outer wall of the body; a groove is arranged in the middle of the body; an opening is arranged on the top portion of the groove; and the inner threads are arranged on the wall of the groove. The fastening part with the inner threads and the outer threads has both of the functions of a screw and a nut; no bolt needs to be arranged on an article in penetrating manner when the multi-layer structure article is fixed by adopting the mode of respectively connecting adjacent layers; the fastening part avoids reducing the strength of the article by arranging screw holes or presetting nuts inside the article; and the fastening part saves process, is more flexible in operation, simultaneously decreases the number of parts, and is convenient in assembly and disassembly.
Description
Technical field
The utility model relates to clamp structure, specifically a kind of fastening piece that has internal and external threads.
Background technique
Being connected and fixed of multilayer object more than three layers, being connected and fixed of sandwich plate that relates to as products such as sofa, swivel chairs and outer cover.If wear fixingly with a bolt type fastening piece, then need attachment hole all align with a plurality of objects, the difficulty that operates is big, and when only outer object being keeped in repair or changing, behind the dismounting fastening piece, the multilayer object can fall apart thereupon or separate.If adjacent layer is connected respectively, then need at least on an object, both to have worn bolt, offer screw again or preset nut in object, and the bolt place of wearing will shift to install with the nut placement, number of spare parts is many, occasion appearance difference that is provided with continuously at needs and the intensity that influences object, it is loaded down with trivial details to add the man-hour operation, and operation is trouble comparatively.
Summary of the invention
The purpose of this utility model is that a kind of fixing, installation that is applied to the multi-layer structure object, the fastening piece that has internal and external threads that has the screw bolt and nut function simultaneously are provided in order to solve above-mentioned the deficiencies in the prior art.
In order to achieve the above object, a kind of fastening piece that has internal and external threads that the utility model is designed, comprise the bolt shape body, described body outer wall has outside thread, the centre is provided with the groove of opening at the top, described groove walls has internal thread, make this fastening piece have the function of screw bolt and nut simultaneously, adopting adjacent layer ways of connecting fixedly during the multi-layer structure object respectively, needn't on object, both wear bolt, offer screw again or in object, preset nut, save operation, operate more flexible.
Improve and replenish as the further of said structure, the utility model also comprises the combination in any of following additional technical feature or these features:
Described outside thread and internal thread are provided with in the same way, further screw outside thread when screwing internal thread, prevent that outside thread from screwing after, externally threaded oppositely loosening when inwardly being threaded into fastening piece such as bolt again.
Described body is step-like cylindrical body, and described body epimere is the externally threaded cylindrical body of going up of outer wall belt; Hypomere is the following cylindrical body after the hole enlargement, and groove is located at down in the cylindrical body.It is the effect of pad that the step place of two section type structure can play conflict spacing, and this one-part form effect structure is good.
Described cylindrical top down is provided with annular protrusion, and it is spacing that the hypomere body is conflicted, and plays the effect of pad.
The external frame of described annular protrusion is an equilateral hexagon, is convenient to general spanner cooperation and tightens body.
The centre of described annular protrusion has in-line or cross bath, is convenient to revolving tool body be screwed.
Described groove is a stepped slot, and the inner of stepped slot has internal thread, and the outer end diameter is greater than inner diameter and form equilateral hexagon, and such design is convenient to screw body with inner hexagon spanner.
The length and the depth of groove of described body epimere are complementary, and make the stackable use of the utility model fastening piece.
The end of described groove is provided with annular protrusion, and it is spacing that body is conflicted, and plays the effect of pad.
A kind of fastening piece that has internal and external threads that has the function of screw bolt and nut simultaneously that the utility model obtains, when adjacent layer is connected and fixed the multilayer object respectively, needn't on object, both wear bolt, and offer screw again or in object, preset nut, avoid reducing object intensity; Save operation, operate more flexible; Not only reduced part number but also attractive in appearance, installed, convenient disassembly.
