Background technology

Traditional open-type window or door often have handgrip to realize lock function; But it can only very work under the condition of limited in the closed or unlatching scope of windowing or opening the door, and ventilates in case need window to open significantly, and this lock function lost efficacy; In addition; Though traditional windowing has position limiting structure,, this structure is easy to destroyed or separate by outside window people; This just makes indoor occupant in a single day leave or is in sleep state that outdoor personnel can open the window easily, and climbing enters the room steals.

The utility model content

The above-mentioned deficiency that the utility model exists to prior art; A kind of multipurpose window door chain group is provided; Be applicable to singly window, building structure such as single open-door, pivot frame, double sash casement window; Parts through each flexible connection limit the unlatching size of windowing, and need not carry out the complicated technology repacking to existing window arrangement and can reach anti-theft effect.

The utility model realizes that through following technical scheme the utility model comprises: the connection chain group that is fixedly set in the holder on forms or the window frame and flexibly connects with it.

Described connection chain group comprises: fixed end, movable end and connecting portion; Wherein: fixed end is fixedly set on the window frame or forms with the holder relative position; The two ends of connecting portion are rotationally connected with fixed end and movable end respectively, and movable end and holder flexibly connect.

Described flexible connection realizes that through pin joint promptly holder is provided with shank, and the correspondence position of movable end is provided with pin-and-hole; Or holder is provided with pin-and-hole, and the correspondence position of movable end is provided with shank.

Described shank comprises: the protruding pin of cylindrical structure and the pin top that is positioned at the top of protruding pin.

Described being rotationally connected realized through hinged, pin joint or socket.

Described connecting portion is integral type platy structure, catamaran type plate-like chain structure, multi-hull type plate-like chain structure or chain, and wherein: catamaran type plate-like chain structure and multi-hull type plate-like chain structure are formed by the junction plate of series connection more than two.

This device window through restriction or the door opening degree; And guarantee that everywhere connection only cooperates under window or door are in the state of complete closure and just can carry out; Make from door or can't handle door chain outside window, be and prevent under the duty that personnel remove the purpose that the window climbing is entered the room outside window thereby reached door chain.

The specific embodiment

Embodiment in the face of the utility model elaborates down; Present embodiment is being to implement under the prerequisite with the utility model technical scheme; Provided detailed embodiment and concrete operating process, but the protection domain of the utility model is not limited to following embodiment.

The door chain group that realizes on embodiment 1 double sash casement window or the double door

As shown in Figure 1, present embodiment comprises: the connection chain group 3 that is fixedly set in the holder 2 on first forms 0 and flexibly connects with it.

Described connection chain group 3 comprises: fixed end 4, movable end 5 and connecting portion 6; Wherein: fixed end 4 is fixedly set on second forms 1 with holder 2 relative positions; The two ends of connecting portion 6 are rotationally connected with fixed end 4 and movable end 5 respectively, and movable end 5 flexibly connects with holder 2.

As depicted in figs. 1 and 2, described flexible connection realizes that through pin joint promptly holder 2 is provided with shank 7, and the correspondence position of movable end 5 is provided with pin-and-hole 8; Perhaps holder is provided with pin-and-hole, and the correspondence position of movable end is provided with shank.

Described shank 7 comprises: the protruding pin 9 of cylindrical structure and the pin top 10 of Long Circle structure that is positioned at the top of protruding pin 9.

Described being rotationally connected through hinged realization.

Described connecting portion 6 is that integral type platy structure and connecting portion 6 are positioned at same perpendicular with movable end 5;

The door chain group that realizes on embodiment 2 pivot frames

As shown in Figure 3, present embodiment adopts same structure to be fixedly set on the forms and window frame of pivot frame.

Embodiment 3 singly window or single open-door on the door chain group that realizes

As shown in Figure 4, described holder 2 is fixedly set in respectively on window frame and the forms with fixed end 4; Described connecting portion 6 is vertically to be provided with movable end 5.
