Abstract
The utility model provides an aluminium-cover composite bolt and a screw cap, comprising a core body made from steel material, an aluminium alloy aluminium-cover covering and connecting to the outer part of the upper end of the core body. The utility model overcomes the defects that in the prior art, the steel material is used for making ,the tinting treatment can not be made, and the color-changing and the decoration effect are lacked, by having the aluminium-cover which is able to be anodized arranged at the outer part of the core body made from the steel material, thereby the bolt and the screw cap are made multicolored, the decoration effect is improved, and the additional value and the economic benefit of the bolt products are greatly increased.
Description
Technical field
The utility model relates to a kind of aluminium cover combined bolt, nut.
Background technique
Known bolt (cap) is generally made with iron and steel material quality, and quality heaviness, and in addition painted processing lack color change and decorative effect.
In view of this design people is studied improvement, invents out novel aluminum cover combined bolt of the present utility model, nut.
Summary of the invention
The purpose of this utility model is that a kind of aluminium cover combined bolt, nut will be provided, and a core body of being made by iron and steel is provided with the aluminium cover that can carry out anodising, give various color outward, thus the decorative effect and the surcharge of promoting bolt, nut.
The technical solution of the utility model is, a kind of aluminium cover combined bolt, nut comprise a core body of being made by iron and steel material quality, and it is outside that an aluminum alloy aluminium cover cover covers, is connected in this core body upper end.
This core body comprises that a polygon head is located at the upper end and has a bead seat; This aluminium cover then comprises: the coincide top of this polygon head of the fit bead seat of this core body of an endoporus that matches with the polygon head of this core body, a root edge, a top cover; Engage between this aluminium cover top cover and this core body polygon head and this aluminium cover root edge and this core body bead seat.
Joint between this aluminium cover and this core body.
The bonding coat that is provided with gluing, engages between this aluminium cover and this core body.
The utility model characteristics and advantage are, overcome in the known technology and made with iron and steel material quality, the quality heaviness, can't paintedly handle, the defective that lacks color change and decorative effect covers at outside the core body that iron and steel material quality makes by the aluminium cover that can carry out anodising, thereby has given bolt, the various color of nut, and promoted its decorative effect, and bolt value-added content of product and economic benefit have been improved greatly.
Description of drawings
Fig. 1 is the cut-away view of the utility model bolt;
Fig. 2 is the cut-away view of the utility model nut.
Drawing reference numeral explanation 1, core body 2, aluminium cover 3,3a, glutinous agent 11, outer screw section 11a, female threaded hole 12, polygon head 13, bead seat 21, endoporus 22, root edge 23, top cover
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1, the utility model bolt comprises: the core body 1 that materials such as an available iron and steel are made; And an aluminium cover 2, these aluminium cover 2 covers cover, be connected with outside on this core body 1, and mat sticks agent 3,3a sticks together this aluminium cover 2, be fixed on this core body 1.
This core body 1 comprises: one can cooperate, lock outer screw section 11, one polygons (as the hexagon) head 12 that connects a nut (end illustrates) is located at the top, and a bead seat 13 is between this head 12 and this outer screw section 11.
This aluminium cover 2 can be made by aluminum alloy, can carry out anodising, and paintedly in addition gives various color.Described aluminium cover 2 comprises: coincideing, to amplexiform the bead seat 13 of this core body, and a top cover 23 is positioned at the upper end to an endoporus 21 with polygon head 12, one root edges 22 of this core body 1 that coincide.Between this top cover 23 and this core body polygon head 12 the glutinous agent 3 of mat cohered, affixed; Between this root edge 22 and this core body bead seat 13 then also the glutinous agent 3a of mat cohered, affixed.
Certainly, can also other junctures between this aluminium cover 2 and the core body 1, engage as mechanical type compact, or other junctures, and the end limits the mode of sticking together with glutinous agent.This aluminium cover is to replace other materials to be convenient to processing (containing painted processing), to give its decorative effect.
In addition, outside this aluminium cover 12 is made divided by aluminum alloy, also can be the material that other can carry out surface treatment such as painted processing, processing.
Because aluminium cover of the present utility model can carry out anodising, manufacture multicolour, and give decorative effect of the present utility model, and aluminium cover quality is slim and graceful, but do not lose the good mechanical properties of core body iron and steel material quality, and cost of the present utility model is all made with aluminum alloy than whole support bolt, more can fall its fabricating cost greatly, thereby increase substantially the surcharge and the economic benefit of bolt product.Moreover whole support bolt is all made with aluminum alloy, and its intensity is also not enough.
The utility model also can be applicable to (as shown in Figure 2) on the nut, and outer cover one aluminium cover 2 on an iron and steel core body 1 engages and formation aluminium cover combined type nut with glutinous agent therebetween.The core body 1 of nut contains female threaded hole 11a, the top of this core body 1 has a polygon head 12, polygon head 12 connects establishes a bead seat 13, aluminium cover 2 then has endoporus 21 identical these heads 12, the glutinous agent 3a of one root edge, 22 mats and this bead seat 13 gluings, and the glutinous agent 3 of a top cover 23 mats and these head 12 gluings.
Described aluminium cover 2 also can be made into ornamental pattern, pattern.
Above-mentioned the utility model only illustrates with most preferred embodiment, to related domain those of ordinary skill, and the various variations of being done, only these change example, all should be included within design of the present utility model and the protection domain.
