Abstract

The utility model provides a key with indicating pattern, which is mainly composed of a key handle frame, an indicating pattern, an obturator and a key core. The indicating pattern is provided inside the key handle frame; the obturator is provided in the cavity between the handle frame and the indicating pattern. The advantages of the utility model are: low manufacturing cost, favorable performance and excellent indicating effect.

Description

A kind of key that has marking pattern body

Technical field: the utility model relates to a kind of key, particularly a kind of key that has marking pattern body.

Background technology: existing band indicates the key of pattern (indicate pattern and comprise various sign signs, pictorial trademark or other pattern etc.) body, mainly is made of the shank of the key and key core two large divisions.Its shank of the key has following several form: 1, the shank of the key is a metallic object, and marking pattern body is arranged on it, and it and key core are an integral body; 2, the shank of the key has metallic object in it, and it is outer to be the inclusion enclave that injected plastics material constitutes through injection moulding, and inclusion enclave is provided with marking pattern body; Or the edge exposure of the metallic object in the shank of the key is outside inclusion enclave; 3, the shank of the key is injection molded by injected plastics material entirely, only is that key core has one section to insert within it, and this shank of the key is provided with marking pattern body.The deficiency that these keys are deposited is: 1, cost of manufacture height.Because the key of each processing all needs to make cover mould correspondingly,, make the corresponding mould of a cover again if this kind key marking pattern body changes.Therefore the cost of key not only comprises the manufacturing cost of self but also will comprise the mould expense, and a mold price is often very high, thereby makes the cost of manufacture height of key.2, performance is often not obvious than dullness and its sign pattern, is difficult to play the effect that indicates pattern.

Summary of the invention: the purpose of this utility model is to propose at the deficiencies in the prior art that a kind of cost of manufacture is low, expression effect good and have the key that has marking pattern body of metal-like.

Can realize the purpose of this utility model by following technical proposals, a kind of key that has marking pattern body, comprise the shank of the key and key core, it is characterized in that: the shank of the key is by marking pattern body in handle frame, the handle frame and that it is connected as a single entity and is located at that the obturator in the cavity constitutes between handle frame and the marking pattern body.

One section of key core is inserted in handle frame and the obturator, and key core is provided with the duct for the injection moulding obturator, has one section in the duct at least by the width of the direction of insertion its rear end width greater than front end.

Key core and handle frame and marking pattern body are an integral body, are provided with the duct for the injection moulding obturator on the key core of the junction of key core and handle frame.

Handle frame and the marking pattern body that is connected as a single entity with it are preferably a kind of metal material, and the table plane of marking pattern body and the table plane of this face obturator are preferably same plane.

Effect of the present utility model is: 1, cost of manufacture is low, because when a kind of marking pattern body on the key changes, the core rod that only needs to change in this key mould gets final product, and does not need to change whole key mould, thereby can greatly reduce the cost of its mould in the key making.This kind mould is that a kind of core rod is embedded in the combination die in the key mould, establishes the pattern of marking pattern body on the core rod.2, the performance sense is strong, marking pattern body is a metallic object, metallic object is once polishing, especially metal such as stainless steel and alloyed copper, its color causes easily gazes at, and adds that its color of obturator that is filled between marking pattern body and the handle frame mostly is black or avy blue, so more can set off out the pattern of marking pattern body, the people is seen and do not forget, thereby reach the effect of sign.

The utility model is described in further detail below in conjunction with drawings and Examples.

Description of drawings:

Accompanying drawing 1 is a schematic diagram of the present utility model;

Accompanying drawing 2 is for removing the structural representation of obturator in the accompanying drawing 1.

The specific embodiment: embodiment 1, referring to accompanying

drawing

1,2, the shank of the key is made of handle frame 1, marking pattern body 2, connector 3 and obturator 4.Handle frame 1, marking pattern body 2 and connector 3 are to be made of assembling die (promptly be made of through being nested key die sleeve and key core rod, its core rod is provided with and indicates pattern) die casting, are generally metal material, also can make by other technology, other material.Indicate pattern and can be various pictorial trademarks, the pattern of confession appreciation, sign property pattern etc.Obturator 4 is generally the nonmetals of injection moulding better performances such as plastics, plastic cement, and it is filled between handle frame 1, marking pattern body 2 and the connector 3 in the cavity by injection moulding.The surface of the surface of obturator 4 and this face marking pattern body 2 is preferably same plane.The thickness of connector 3 is equal to or less than the thickness of marking pattern body 2.Such setting is the requirement of Shooting Technique.Key core 5 is inserted in the obturator 4 by the hole on the handle frame 1, which is provided with a duct 6, has one section in this duct at least by the width of direction of insertion (key core 5 is inserted the directions to handle frame 1) its rear end width greater than front end, and its effect is to prevent that key core 5 from coming off.Be filled with obturator 4 in the duct 6, but obturator 4 passing hole channels 6 injection mouldings in the handle frame 1 enter, also can enter by the hole injection moulding is set on the handle frame.The effect in duct 6 is: 1, for injection moulding obturator 4 usefulness; 2, be used for being connected of key core 5 and the shank of the key.The shape that duct 6 is positioned at handle frame 1 outside can be designed to have ornamental shape.

Embodiment 2: referring to accompanying

drawing

1,2, this routine difference from Example 1 only is that its key core 5 and handle frame 1, marking pattern body 2 and connector 3 are all an integral body, is to be formed by assembling die die casting, and other content is all same with embodiment 1, no longer repeats at this.

Claims

1, a kind of key that has marking pattern body comprises the shank of the key and key core, it is characterized in that the shank of the key is by marking pattern body in handle frame, the handle frame and that it is connected as a single entity and is located at that the obturator in the cavity constitutes between handle frame and the marking pattern body.

2, by the described key that has marking pattern body of claim 1, one section that it is characterized in that key core is inserted in handle frame and the obturator, key core is provided with the duct for the injection moulding obturator, has one section in the duct at least by the width of the direction of insertion its rear end width greater than front end.
