Description

Manual heavy lifting window

Technical Field

The utility model relates to the technical field of doors and windows, in particular to a manual heavy lifting window.

Background

In order to meet multiple requirements of attractiveness, fire protection and safety at the same time in public places such as superstores, exhibition halls, hospitals and stations, the window body is required to be large in size and good in lighting performance, the angle range of opening of the window body is required to be wide enough, the ventilation performance is excellent, and meanwhile, the height of opening of the window body is also required to be limited, so that people are prevented from falling off when approaching the window body. However, in china, most of such public places still adopt the window structures of the traditional translational flat-open or common forward and backward push-pull modes, and the two types of windows have more disadvantages in use: if a horizontally-sliding side-hung window mode of left-right push-and-pull is adopted, the left space and the right space are not shielded when being opened, and the required safety performance cannot be met; when a common front-back push-pull mode is adopted, the wide opening angle cannot be met, the ventilation performance is poor, and the ventilation quantity is small. Meanwhile, when the window body of the two modes is manufactured to be large in size, the weight of the window body is heavy, and therefore the window body is inconvenient to operate manually.

At present, part of public places also adopt a window structure of an up-down lifting type, the up-down lifting window is different from the window structure of the traditional translation flat-open type and a front-back pushing and pulling mode, the up-down lifting window adopts an opening mode of up-down lifting by a lifter, and the lifter relieves the self weight of the window, so the operation is very convenient. However, the existing top-bottom sliding window is not widely used, and the reason for this is that the top-bottom sliding window manufactured in the current market generally adopts the following two lifting structures to operate: firstly, adopting a single lifting and closing mode that an outer side upper window sash is fixed and an inner side lower window sash is movable from top to bottom; and secondly, a double-lifting closing mode that the upper window sash and the lower window sash can reciprocate up and down is adopted. The two kinds of vertical sliding windows have the following technical problems when used in such a scene: on one hand, when the lower window sash is adopted for movement, if the size of the lower window sash is smaller, the ventilation effect is poorer, and if the size of the lower window sash is designed to be larger, if the height of an operator is not enough, for example, if the operator is a child, the operator cannot conveniently reach the handle of the lower window sash positioned above, so that the lifting window cannot be closed smoothly; on the other hand, because the lower window sash is movably opened, great potential safety hazard also exists.

SUMMERY OF THE UTILITY MODEL
