Description
Technical field
The utility model relates to a kind of flat-open door and window, is specifically related to little ventilating mechanisms of flat-open door and window.
Background technology
Flat-open door and window is a kind of door leaf or sash to be hinged on door and window on doorframe or window frame.Traditional flat-open door and window is all that large scale is opened or closes, be to prevent that bar from damaging and the indoor object of wind disheveled when running into strong wind weather, flat-open door and window is closed condition normally, so atmosphere draught-free in the room, if someone does not carry out convection current by the air in smoking or room in the room for a long time, will be unfavorable for that people's is healthy.And after the large scale door and window, extraneous dust or noise pollute again, so be necessary to study a kind of mechanism that carries out little ventilation for flat-open door and window specially.
Summary of the invention
In view of the deficiency that background technology exists, the technical problems to be solved in the utility model is to provide a kind of little ventilating mechanisms of flat-open door and window simple in structure, easy to use.
for this reason, the utility model takes following technical scheme to complete: a kind of little ventilating mechanisms of flat-open door and window, comprise drive link and U-shaped keeper, described drive link is connected with handle, it is characterized in that being hinged with respectively on described drive link support plate and short slab, one end of described support plate and short slab is respectively equipped with bearing pin, described support plate be provided with short slab on the chute of bearing pin coupling, and the bearing pin on described short slab slides in described chute, described support plate is provided with locating clip, and be provided with shifting chute on locating clip, described shifting chute is corresponding with described chute, the U-shaped groove coupling of the bearing pin on described support plate and described U-shaped keeper, and can slide in U-shaped groove.
Described locating clip is working of plastics.
this structure of the present utility model, in the little ventilation of needs, pull handle 90 degree, the drive drive link moves, make the support plate bearing pin insert in the U-shaped groove of U-shaped keeper, then promote bar, bar is exerted oneself after being opened to a certain degree a little, bearing pin on short slab is stuck in the end with shifting chute on flexible locating clip, bearing pin on short slab just is fixed in shifting chute, and play and run into the effect that high wind can not closed naturally, bearing pin on support plate moves on to the middle part of U-shaped groove, bar just is fixed and carries out little ventilation like this, when bar is closed, a little firmly pull, bearing pin on short slab just breaks away from the end of shifting chute, then, short slab and support plate close, make with drive link and be in a straight line, do not affect the unlatching of bar next time or close, realize the flat effect of opening, this mechanism structure advantages of simple, succinct during use, convenient, has good practicality.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is structure chart of the present utility model;
Structure chart of the present utility model when Fig. 2 is the door and window closure;
Fig. 3 is the structure chart of the utility model drive link;
Fig. 4 is the structure chart of the utility model locating clip;
State diagram when Fig. 5 is the little ventilation of the utility model door leaf or sash.
The specific embodiment
Accompanying drawing has represented the technical solution of the utility model and embodiment, and the below further describes each details and the operating principle thereof of embodiment more by reference to the accompanying drawings.
as shown in the figure, little ventilating mechanisms of this flat-open door and window, comprise drive link 1 and U-shaped keeper 10, described drive link 1 is arranged on door leaf or sash, and be connected with handle for driving on door leaf or sash, U-shaped keeper is arranged on doorframe or window frame, be hinged with respectively support plate 2 and short slab 3 on drive link 1, one end of described support plate 2 and short slab 3 is respectively equipped with bearing pin 4, 12, described support plate 2 be provided with short slab 3 on the chute 5 of bearing pin 4 coupling, and the bearing pin on short slab 34 is in the support plate 2 interior slips of upper hopper chute 5, described support plate 2 is provided with locating clip 6, locating clip 6 is provided with shifting chute 7, this shifting chute 7 is corresponding with the chute 5 on support plate 2, bearing pin 12 on described support plate 2 and the U-shaped groove of described U-shaped keeper 10 11 couplings, and can be in the interior slip of U-shaped groove 11.
The utility model carries out following work: when opening sash fully as needs, only need to close fully in situation at bar, with handle Rotate 180 degree, with transmission drive link 1, make the U-shaped groove of the bearing pin 12 U-shaped keepers of disengaging on support plate 2, then push door leaf or sash open, the door and window with traditional is the same like this, open or close, realize the flat effect of opening.in the time will carrying out little ventilation, rotate handle 90 degree, mobile drive link 1, make bearing pin 12 on support plate 2 insert the U-shaped groove 10 of U-shaped keeper 10, then push door leaf or sash open, push door leaf open, in the process of sash, support plate 2 and short slab 3 strut, simultaneously, the chute 5 interior movement of bearing pin 4 on short slab 3 on support plate 2, the also i.e. interior movement of shifting chute on locating clip 67, after door leaf or sash are passed certain position, because locating clip 6 is working of plastics, has certain elasticity, as long as firmly just make bearing pin enter the end of shifting chute 7 a little, avoiding meeting the high wind door and window closes naturally, so when the bearing pin 4 on short slab 3 slides into an end of shifting chute 7, just snap onto an end of shifting chute 7, position, at this moment, door leaf or sash are just opened slightly, indoor with extraneous air is circulated, the process that flat-open door and window carries out little ventilation like this.When closing door leaf or sash, a little firmly pull door leaf or sash, bearing pin 4 on short slab 3 is slided withdraw from the interference fit end of shifting chute 7, in door leaf or sash close the process of doorframe or window frame, bearing pin 12 on support plate 2 breaks away from the U-shaped groove 10 of U-shaped keeper, and support plate 2 and short slab 3 also close, and are on same straight line with drive link 1, door leaf or sash just can normally be closed like this, and the support plate 2 and the short slab 3 that are arranged on door leaf or sash do not affect normal opening and closing.This structure of the present utility model, advantages of simple, easy to use, succinct, be applicable to various flat-open door and window.
