Abstract

The present invention relates to a kind of composite dowel with plastic sleev.The employing composite dowel with plastic sleev is a fastening piece, part wire nail and the screw function in the alternative metals fastening piece preferably, and have for being in the indoor and outdoor decoration service and supporting trim fasteners have characteristics such as anti-water, antiacid caustic corrosion, long service life.

Description

Composite dowel with plastic sleev

The present invention relates to a kind of composite dowel with plastic sleev.

For a long time, metal is to make screw in the fastening piece, garden nail main raw material(s), is widely used, but is subject to other factors and causes itself to be corroded to get rusty, have influence on working life owing to metal exists.In sum, can see that metal fastenings screw and garden follow closely existing problem and shortage.

Task of the present invention at first is in order to provide a kind of high-quality plastics telescopic master and slave dowel member, it was both with a wide range of applications, can be used for for example as the close fastening function of water tank, water pipe, urinal, panel, wall lamp, picture frame, placard or the like and body of wall by the alternative metals fastening piece.Characteristics such as composite dowel with plastic sleev has firm, attractive in appearance, anti-water, antiacid caustic corrosion, long service life.Secondly, task of the present invention is for a kind of composite dowel with plastic sleev member of saving raw material metal is provided, for relaxing the supply requirement amount of metallic material.

Task of the present invention realizes in the following manner, at first the present invention by injection machine by mould, respectively plastic pellet is fixed to the function that telescopic female nail pipe and the telescopic master and slave dowel of the sub-rivet disome of plastics synthetic plastic are brought into play fastening object through injection moulding.Garden column type, square column type, hexagonal column type, anistree column type isotactic lattice are arranged in three-dimensional contouring.In the fatiscent flange brim of telescopic female nail pipe upper end design, lower end is that counterincision shape or four is split the shape pipe wall body.The inboard design of tube wall has suitable chamfer wall, the sub-rivet of plastics to have half knob type, countersunk head type, forward type and self-taped type screw and design that the sub-rivet of long-neck ansa, garden circle ansa, hook ansa or the like specification moulding is arranged.During use, need only bore a corresponding hole of recommending on the main component or on the body of wall in advance, telescopic female nail pipe can be inserted and recommend in the hole, and then with the female nail of sub-rivet propelling pipe orifice, make the sub-shaft of rivet enter female nail pipe predetermined position through actions such as hammerings, sub-rivet volume rigid get into female nail pipe force female nail pipe split the wall position to around dilate, because the sub-shaft of rivet design of plastics has contrary chamfer wall, contrary chamfer of group rivet and the suitable chamfer disome of female nail inner tube wall form strong fastening function when closed, simultaneously, have certain robustness and have anti-water by composite dowel with plastic sleev, antiacid caustic corrosion, long service life characteristics such as easily manufactured simple in structure have certain social benefit and economic benefit so promote the use of composite dowel with plastic sleev.

Below in conjunction with accompanying drawing composite dowel with plastic sleev member of the present invention is further described, wherein:

Fig. 1 is embodiment of the invention composite dowel with plastic sleev two body portion moulding structure schematic perspective views.

Fig. 2 is the closed fastening schematic perspective view of embodiment of the invention composite dowel with plastic sleev disome.

See figures.1.and.2, the composite dowel with plastic sleev member is according to different fastening functional requirements, and its plastics can adopt PVC, vinyl benzene, polypropylene, polyethylene, polyamide, ABS or the like raw materials for plastics production to make through injection moulding respectively.

Claims

1, a kind of composite dowel with plastic sleev member, it is characterized in that described plastics are is female nail pipe of plastic sheath cartridge type and the sub-rivet of plastics through injection machine by mold injection molding, garden column type, square column type, hexagonal column type, anistree column type isotactic lattice, the fatiscent flange brim of telescopic female nail pipe upper end design are arranged in moulding, and the lower end design has counterincision shape or four to split the shape pipe wall body, the inboard design of tube wall has suitable chamfer wall.Sub-rivet has half knob type, countersunk head type, forward type and self-taped type screw and design to have long-neck ansa, garden circle ansa hook ansa or the like the sub-rivet of moulding, the design of sub-shaft of rivet middle part to have contrary chamfer wall to form strong fastening function.

2, according to the described composite dowel with plastic sleev of claim 1, it is characterized in that described plastics can select for use PVC, vinyl benzene, polypropylene, polyethylene, polyamide and ABS or the like raw materials for plastics production to make through injection moulding, bring into play different fastening functional requirements.
