Abstract
The utility model provides a compound key which comprises a key pole part, wherein the key pole part comprises an aluminum profile and a copper profile with an irregular trapezoidal cross section, wherein a ladder-type groove matched with the bottom of the copper profile is longitudinally formed in the middle of the aluminum profile, and the copper profile and the aluminum profile are combined in a tenon-mortise connection manner. Compared with the prior art, the compound key has lower cost and basically unchangeable rigidity.
Description
Technical field
The utility model relates to a kind of key, specifically a kind of complex key that is made of different materials.
Background technology
Up to the present, almost the key more than 90% all uses copper or iron, and copper is to do the key best material, and cost also is the highest; Iron is done the key performance and is taken second place, but iron is easy to get rusty, and influences attractive in appearance.Many manufacturers attempted use aluminium or zinc and made key in order to save cost, found that these two kinds of materials of aluminium or zinc are antitorque and wear-resisting all not reach requirement, therefore, used copper to make key with iron and had almost become general knowledge.
The utility model content
The purpose of this utility model is for providing a kind of good rigidly, the complex key that cost is low.
The technical scheme that realizes the foregoing invention purpose is as follows:
Complex key comprises key bar portion, and described key bar portion comprises that an aluminium extruded sections and cross section are the copper section bar of isosceles trapezoid, and the middle part of described aluminium extruded sections vertically has in the suitable trapezoidal groove in copper section bar bottom, and described copper section bar combines with the aluminium extruded sections tenon fourth of the twelve Earthly Branches.
The upper surface of described aluminium extruded sections is curved, and described trapezoidal groove is positioned at the bottom of arc.
Has tartar on the described copper section bar.
One end of described key bar portion has plastic handle and reinforces the tenon mouth.
The utility model complex key solves the difficult problem of prior art, the change of its maximum is to have abandoned to use fully copper or iron to make key, but adopt two kinds of section bar mortice and tenon joints of copper and aluminium to be in the same place, key for equal volume, the consumption of complex key copper has reduced 2/3rds, and the rigidity of key has but reached the intensity of full copper key substantially.
The utility model had both possessed the outward appearance and the rigidity of copper key, and cost reduces again much, will be subjected to the market favor.
Description of drawings
Fig. 1 is the structural representation of key bar of the present utility model portion.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, complex key comprises key bar portion, and described key bar portion comprises that one is the aluminium extruded sections 1 of sheet shape and the copper section bar 2 that cross section is isosceles trapezoid substantially, the middle part of described aluminium extruded sections vertically has in the suitable trapezoidal groove in copper section bar bottom, and described copper section bar combines with the aluminium extruded sections tenon fourth of the twelve Earthly Branches.
The upper surface of described aluminium extruded sections is curved, and described trapezoidal groove is positioned at the bottom of arc.
Has tartar 3 on the described copper section bar.
One end of described key bar portion has plastic handle and reinforces tenon mouth 4.This design can be strengthened the plastic handle of key and combining of key bar portion.Certainly also can form metal (aluminium) handle of one at an end of key bar portion.
Claims (4)
1. complex key, comprise key bar portion, it is characterized by: described key bar portion comprises that an aluminium extruded sections and cross section are the copper section bar of isosceles trapezoid, and the middle part of described aluminium extruded sections vertically has in the suitable trapezoidal groove in copper section bar bottom, and described copper section bar combines with the aluminium extruded sections tenon fourth of the twelve Earthly Branches.
2. complex key according to claim 1 is characterized by: the upper surface of described aluminium extruded sections is curved, and described trapezoidal groove is positioned at the bottom of arc.
