Abstract
A door handle comprises a handle body and a metal insert, wherein the handle body is provided with a plastic part, and the metal insert is used for installing and positioning the handle body. The handle body includes a connecting portion and a holding portion; a communicated cavity is arranged inside the connecting portion and the holding portion; the cavity extends to the outer end portion of the holding portion; and the insert is tightly installed inside the whole cavity and fixedly connected with the handle body. The door handle adopts an integral embedded plastic injection structure; the door handle body and the insert can be positioned without connecting pins; the door handle has simple structure; and the insert is embedded into the entire cavity of the door handle body, thereby only the portion of the door handle body is burned up even if special conditions such as fire disasters and the like happen, a door can be opened as the inert extending to the holding portion still exists, and the possibility of escape is increased. Besides, as the insert extends to the holding portion, the door handle improves the strength of products and has better use stability.
Description
(1) technical field
The utility model relates to a kind of door handle that is used for shutter door.
(2) background technology
In the past, door handle comprised the handle body of plastic material and the mold insert of metal material, and mold insert 1 only is embedded into the connecting portion of handle body, and, need be connected and fixed mold insert and plastic material by connecting pin 2, as Fig. 1, shown in Figure 5, the grip part does not have metal inserted piece; Because metal inserted piece only is embedded in connecting portion, in case run into fire, the thorough after-flame of the handle body of plastic material, only the mold insert by connecting portion can't open the door, can't escape, and has potential safety hazard; And the connecting pin place is owing to be stress point, and plastic material herein breaks easily; Do not fill metal inserted piece in the grip part, product strength is low, and stability in use is poor, and particularly at low temperatures, the plastic material freexing tolerance is poor, and bursting by freezing easily has influence on the normal use of door.
(3) summary of the invention
The technical problems to be solved in the utility model provides a kind of connecting portion and need not the connecting pin location, and metal inserted piece extends to the grip part, can avoid the influence of fire to using as far as possible, the door handle that intensity is strong.
For this reason, the utility model is taked following technical scheme:
A kind of door handle, include the handle body of plastic, the metal inserted piece of the described handle body of installing and locating, described handle body is made up of connecting portion, grip part, cavity for being communicated with in described connecting portion, the grip part, described cavity extends to the outer end of grip part, described mold insert snugly fits in the described whole cavity, and affixed with handle body.
Described handle body and mold insert injection mo(u)lding.
One end of described mold insert extends connecting portion, and described mold insert extension is provided with draw-in groove.
In the whole built-in described cavity of described mold insert, and the mold insert that is positioned at connecting portion is provided with internal thread.
The mold insert that is positioned at the grip part is concavo-convex alternating structure.
The mold insert that is positioned at the grip part is a hollow structure.
The utility model has the advantages that: 1, adopt the whole injection structure that embeds, door handle body and mold insert need not the connecting pin location, and be simple to operate; 2, all embed in the whole cavity of door handle body mold insert is arranged, even if run into special circumstances such as fire, the door handle body part that has been after-flame only also, the mold insert that extends to the grip part still exists, and can open door, has improved the possibility of escape; 3, mold insert extends to the grip part, has improved the intensity of product, and stability in use is better; 4, the mold insert that is positioned at the grip part becomes concavo-convex alternating structure, and the grip part cavity is form fit with it, and mold insert and grip part cavity closely cooperate, and have improved the connection steadiness.
