Abstract
The utility model provides a door handle, belonging to the field of mechanical technology and solving the problems of low safety, poor stability and the like since an insertion piece of the conventional door handle is only inserted into a connection part and a closed door cannot be opened when a handle body is burnt out. The door handle comprises a body made from plastic material and an insertion piece made from metal material, wherein the body comprises a connection part and a holding part, which are connected into a whole; a cavity in the connection part and a cavity in the holding part are communicated and extend to an outer end of the holding part; the insertion piece is completely arranged in the whole cavity and fixedly connected with the body; the insertion piece at the connection part is provided with an internal thread; and the insertion piece is of a hollow structure. The door handle has the advantages of simple structure, high strength and good stability.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of door handle that is used for the switch door.
Background technology
In the past, door handle comprised the handle body of plastic material and the mold insert of metal material, and mold insert only is embedded into the connecting portion of handle body and is fixed together mold insert and handle body through connecting pin, and the grip part of handle body 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 through connecting portion can't open the door, can't escape, and exists potential safety hazard.Because the connecting pin place is a stress point, and the plastic material here breaks easily, and metal inserted piece is not filled in the grip part, and product strength is low, and stability in use is poor, and particularly at low temperatures, the plastic material freexing tolerance is poor, bursting by freezing easily has influence on the normal use of door simultaneously.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, proposed a kind of simple in structure, intensity strong, the door handle of good stability.
The purpose of the utility model can realize through following technical proposal: a kind of door handle; Comprise and adopt plastic material body of processing and the mold insert that adopts metal material to process; Described body comprises connecting portion and the grip part that is connected as a single entity; It is characterized in that the inside of described connecting portion and the inside of grip part have the outer end that the cavity that is connected and described cavity extend to the grip part, described mold insert integral body is built in the described whole cavity and described mold insert and body are connected; The described mold insert that is positioned at the connecting portion place has internal thread, and described mold insert inside is hollow structure.
Compared with prior art; All embed in the body interior whole cavity of this door handle mold insert is arranged; Even if run into special circumstances such as fire, the body part of door handle that has been after-flame only also, and the mold insert that extends to the grip part still exists; Thereby can open door through mold insert, improve the possibility of escape.Mold insert extends to the grip part simultaneously, has improved the intensity of product, and stability in use is better.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, body; 11, connecting portion; 12, grip part; 2, mold insert.
The specific embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As shown in Figure 1; This door handle comprises and adopts plastic material body of processing 1 and the mold insert 2 that adopts metal material to process, and body 1 comprises the connecting portion 11 and grip part 12 that is connected as a single entity, and the inside of connecting portion 11 and the inside of grip part 12 have the outer end that the cavity that is connected and cavity extend to grip part 12; Mold insert 2 integral body are built in the whole cavity and with body 1 and are connected; Mold insert 2 inside are hollow structure, can save the manufacturing raw material of mold insert 2 like this, reduce production costs; The mold insert 2 that is positioned at connecting portion 11 places simultaneously has internal thread, can this door handle be installed on the corresponding door through internal thread.
All embed in the body 1 inner whole cavity of this door handle mold insert 2 is arranged; Even if run into special circumstances such as fire, body 1 part of door handle that has been after-flame only also, and the mold insert 2 that extends to grip part 12 still exists; Thereby can open door through mold insert 2, improve the possibility of escape.Mold insert 2 extends to grip part 12 simultaneously, has improved the intensity of product, and stability in use is better.
