In figure, 100, support; 200, fixed axis; 300, rocking handle; 310, connecting portion; 400, rotating disk; 410, spacing hole; 420, connecting pin; 500, main body; 510, guide wheel; 520, connection cord; 600, bearing; 700, handle.
Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, this self-locking device being used for window opening device comprises support, support is horizontally arranged with fixed axis, fixed axis is arranged with rocking handle and rotating disk, described rotating disk is between rocking handle and support, and described rocking handle can drive rotating disk synchronous axial system, and rocking handle is fixed with connecting portion, fixed axis is provided with the latch running through connecting portion and fixed axis successively, and described latch can make connecting portion static.
Based on above-mentioned feature; in the process that window opening device uses; staff's energy rotation crank, rocking handle drives rotating disk synchronous axial system, realizes closing up or closing between sash and window frame; fixed axis is provided with latch; when folding angle between sash and window frame reaches predetermined folding angle, latch can realize the self-locking of rocking handle, avoids and closes up suddenly between sash and window frame and cause damage to sash; reduce the generation of the phenomenon in application life, improve the application life of sash.
Above-mentioned fixed axis laterally and run through and be arranged in frame, fixed axis is provided with two holders, two holders are arranged at the both sides of frame respectively, two cage bolts are connected in frame, thus two holders all can produce tractive force to holder, improve the steadiness that fixed axis is installed, avoid owing to occurring between fixed axis and support to loosen, and cause closing up suddenly between sash and window frame and cause the damage of sash, reduce the generation of the phenomenon in the application life of sash.
Preferably, rotating disk offers multiple spacing hole, be inserted with connecting pin in a spacing hole wherein, in use, the side of connecting pin is resisted against on rocking handle; rocking handle can produce thrust to connecting pin in rotation process; and one end of connecting pin is inserted on rotating disk, thus thrust can drive rotating disk circumference to rotate, and drives rotating disk circumference to rotate; to facilitate the use of user, improve rotational efficienty by rocking handle.
Further, rocking handle is movably set with handle, expands the spacing between the grip point of user and fixed axis, save the thrust of user's required applying when rotation crank, facilitate the use of user, improve rotational efficienty.
Support is provided with guide wheel group, is provided with connection cord between guide wheel group and rotating disk, one end of connection cord is connected with rotating disk, and one end is connected with sash through guide wheel group, and user rotates rotating disk and sash can be driven to open or close.
Guide wheel group comprises main body, main body is articulated with two guide wheels be arranged in parallel, connection cord between two guide wheels and connection cord can contact with two guide wheels, the outer rim of guide wheel offers link slot, in the course of the work, connection cord is positioned at link slot, avoids between connection cord and guide wheel and skidding occurs, and the phenomenon causing sash and window frame to collide produces, improve rotational efficienty.
Fixed axis is arranged with bearing, the two ends of bearing contact with holder with rotating disk respectively, arranging of bearing can change the sliding friction between rotating disk and holder into rolling friction, decreases the frictional force between rotating disk and holder, improves the rotational efficienty of rotating disk.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
