It contains the hollow casing of handle appearance metal and fills the chipware be equipped with the manufacturing locating hole on the packing chipware, it inlays to fill the chipware in the inner chamber of the hollow casing of handle appearance metal inlayed the packing pin on making the locating hole, its characterized in that is in be equipped with pin reinforcement sleeve on the manufacturing locating hole, it pins for multistage tapering circular cone to pack the pin, multistage tapering circular cone pin with the hookup of pin reinforcement sleeve close -fitting. Its purpose can prevent electroplating water infiltration pin packing clearance in order to design one kind, and makes the compound tool to lock handle of metal who fills the pin and be difficult for falling out. Compared with the prior art, the product disability rate that has production is low, and the locking force of filling between pin and the manufacturing locating hole is lasting, stable, and metal composite article appearance is difficult for receiving advantages such as destruction.
Description
Technical field
The utility model relates to goods, particularly a kind of metal composite lock handle by casting of metals such as copper, zinc, stainless steels.
Background technology
The similar lock handle of existing casting of metals goods, door and the product such as furniture pull, metal handicrafts are all generally solid constructions, in the fabrication process, the materials such as a large amount of high quality zinc, aluminium, copper alloy and stainless steel need be consumed, manufacturing cost is high, Heavy Weight, cost of transportation is high. particularly solid article due to shrinkage factor in manufacture process large, the glacing flatness of dimensional accuracy and profile is difficult to ensure, therefore, to manufacture level and process specifications also higher.
On October 04th, 2006 State Intellectual Property Office to disclose a kind of patent No. on the net in Intellectual Property in China be 200520117853, denomination of invention is die cast metal or casting composite article, this technical scheme comprises goods profile metal hollow housing and fills chipware, filling chipware is embedded in the inner chamber of goods profile metal hollow housing, described filling chipware is provided with the locating hole being convenient to processing and manufacturing, described locating hole is embedded with filling pin.The problems such as existing casting of metals goods manufacturing cost is high although this technical scheme solves, Heavy Weight, also there is many weak points in it:
1, due to after die cast metal or casting composite article blank complete, follow-uply also to electroplate, in electroplating process, plating water can be infiltrated by the gap between pin and locating hole to be stayed in gap, carrying out drying in the process with baking vanish after having electroplated, the plating water stayed in gap can be exuded to metal composite product surface, and corrosion failure surface electrical coating causes metal composite goods to scrap.
2, because the basic material of locating hole is for filling chipware, hardness is very low, the persistence of filling the coupling mechanism force between pin and locating hole is very unstable, when the impact that metal composite goods are expanded with heat and contract with cold, fill pin easily to drop out from metal composite goods, metal composite goods profile is damaged, and causes metal composite goods to scrap.
3, for the metal composite goods of similar lock handle, because handle uses frequent and vibration, the pin be embedded on locating hole also easily comes off, and causes metal composite lock handle to scrap.
Summary of the invention
The purpose of this utility model is that design one can prevent plating water from infiltrating pin filling gap, and the metal composite lock handle that filling pin is not easily dropped out.
In order to achieve the above object, the utility model adopts following technical solution: a kind of metal composite lock handle, it comprises handle profile metal hollow housing and fills chipware, described filling chipware is provided with manufacture locating hole, described filling chipware is embedded in the inner chamber of described handle profile metal hollow housing, described manufacture locating hole is embedded with filling pin, it is characterized in that being provided with pin reinforcing sleeve on described manufacture locating hole, described filling pin is multistage tapered conical pin, and described multistage tapered conical pin connects with described pin reinforcing sleeve close-fitting.
The utility model, in order to easily manufactured, enable pin reinforcing sleeve and handle be connected in one, arranges further technique scheme: described pin reinforcing sleeve and handle profile metal hollow die casting for shell are in one.
The utility model is combined closely with handle housing to enable auxiliary pin of filling, and there is cascaded coordination close-coupled, technique scheme is arranged further: described multistage tapered conical pin is followed closely by the circular cone pin of two-stage tapering and one-level round pin and formed.
The utility model is surprisingly pulled out to prevent auxiliary pin of filling, and arranges further: be provided with expanded bore in the bottom of described multistage tapered conical pin, be provided with expansion drift bottom described locating hole technique scheme.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, the present embodiment comprises handle profile metal hollow housing 2, fills chipware 1 and multistage tapered conical pin 3, wherein:
Described filling chipware 1 is provided with and manufactures locating hole 10 (shown in Fig. 3), described filling chipware 1 is embedded in the inner chamber of described handle profile metal hollow housing 2 by die casting manufacturing process, described manufacture locating hole 10 is provided with pin reinforcing sleeve 4, described pin reinforcing sleeve 4 and the die casting of handle profile metal hollow housing 2 are in one, enable pin reinforcing sleeve and handle be connected in one, described multistage tapered conical pin 3 connects with described pin reinforcing sleeve 4 close-fitting.Owing to having set up pin reinforcing sleeve 4 and being connected in one with handle profile metal hollow housing 2, the area and intensity of the fitting face that multistage tapered conical pin 3 is locked increases further, ensure that the coupling mechanism force that multistage tapered conical pin 3 connects with handle profile metal hollow housing 2.
As shown in Figure 5, described multistage tapered conical pin is followed closely 7 by the circular cone pin 5,6 of two-stage tapering and one-level round pin and is formed, after first order circular cone pin 6 and described pin reinforcing sleeve 4 close-fitting, multistage tapered conical pin is fixedly secured on handle profile metal hollow housing 2, second level circular cone pin 5 and described pin reinforcing sleeve 4 are more further after close-fitting, the gap existed between multistage tapered conical pin and pin reinforcing sleeve 4 can be eliminated further, effectively prevent metal composite lock handle from electroplating process, electroplating water and infiltrate in pin filling gap.
Again as shown in Figure 4, Figure 5, be provided with expanded bore 8 in the bottom of described multistage tapered conical pin 3, bottom described manufacture locating hole 10, be provided with expansion drift 9.After multistage tapered conical pin 3 embeds manufacture locating hole 10 as filling member, under the effect of external force, the expanded bore 8 of multistage tapered conical pin 3 expands outwardly by the impact expanding drift 9, make the lower end of multistage tapered conical pin 3 and described filling chipware 1 close-coupled further, it can effectively prevent auxiliary pin of filling from surprisingly being pulled out.
In sum, the utility model compared with prior art has the following advantages:
The metal composite lock handle product rejection rate of 1, producing reduces greatly.
2, auxiliary pin of filling not easily is drawn out.
The coupling mechanism force of 3, filling between pin and locating hole is lasting, stable.
4, metal composite goods profile is not easily damaged.
The above is preferred embodiment of the present utility model; should be understood that; under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some distortion and improvement, these also should be considered as the protection domain belonging to utility model.
