Suspended sash window opening/closing transmission mechanism

Abstract

The invention discloses a suspended sash window opening / closing transmission mechanism. The mechanism comprises a suspended sash window arranged on a wall surface, and is characterized in that a plurality of fixed supports are uniformly distributed on the inner side of the wall surface, a sliding support is arranged on each fixed support, a driving rod capable of linearly sliding back and forth along the sliding supports is arranged on the sliding supports in a penetrating mode through sliding clearance fit and is connected with the opening end of the suspended sash window through transmissionrods, and the two ends of each transmission rod are connected with the driving rod and the opening end of the suspended sash window through steering part sleeves respectively; each steering part sleeve is formed by hinging a connecting base and a steering knuckle, the connecting base is fixed to the driving rod or the opening end of the suspended sash window, the steering knuckle is hinged to theend of the corresponding transmission rod, and a hinge shaft is perpendicular to a hinge shaft between the corresponding connecting base and the corresponding steering knuckle. The suspended sash window opening / closing transmission mechanism is simple in structure, convenient to control and capable of ensuring synchronous opening and closing control of a long-distance suspended sash window and tight closing of the suspended sash window.

Description

technical field [0001] The invention relates to the field of building ventilation control, in particular to a transmission mechanism for opening and closing a hanging window. Background technique [0002] In order to meet the needs of building ventilation and smoke exhaust functions, many buildings have hung windows at high places on the wall, including top-hung windows, middle-hung windows, bottom-hung windows, etc. There are also many ventilation and smoke exhaust skylights that also use hanging window structures. In order to ensure the ventilation effect in application, most of the hanging windows are set in the high places of buildings where human operation is inconvenient and remote control is required to open and close, and they are arranged continuously or at intervals along the long longitudinal strip of the building. This long-distance layout makes it difficult to configure and use the commonly used torque-type window opening mechanisms, including: [0003] 1. The ...

AI Technical Summary

Problems solved by technology

[0003] 1. The torque type window opening mechanism is to open the window by rotating the crank arm connecting rod distributed in different positions of the main shaft rod under the action of the driving device. The main shaft rod is affected by friction force, torque reaction force and other aspects, so that The farther the distance from the driving device is, the greater the deviation of the torsion angle of the connecting rod connected to the main shaft rod is, coupled with the complex rotation transmission deviation between multiple rotating parts, the opening and closing of the hanging window under the action of the same driving device cannot be kept synchronized and cause hanging. The window is not closed tightly, so it is difficult for this torque type window opening mechanism to simultaneously control a long hanging window

[0004] 2. In terms of structure, due to the above-mentioned rotation transmission error problem, it will inevitably cause uneven force on the transmission branch connecting rod connected to the main shaft, resulting in excessive local load and damage to the window opening mechanism and hanging window

[0005] 3. Affected by the function of the window opening mechanism, in the application, the long hanging window can only be divided into multiple small sash and small window frame combinations, so a large number of tightness and cold bridge problems between the sash and the window frame will be added, including The production and installation of small-sized hanging windows, the opening and closing devices and supporting electrical facilities will greatly increase the construction cost, greatly increase the energy consumption of the product, and increase the number and difficulty of maintenance and repair.

[0006] 4. Due to the large number of opening and closing mechanisms similar to hanging windows and the difficulty in maintenance, the opening and closing mechanisms of many building hanging windows are damaged and cannot be repaired in time. It is impossible to ensure the normal opening and closing of hanging windows for ventilation and smoke exhaust, which seriously affects the building ventilation environment and fire and smoke applications

[0007] Through the above analysis, it can be seen that the current torque type window opening mechanism will inevitably produce large rotation and bending deformation when opening and closing the hanging window, which will lead to problems such as asynchronous opening and closing of the hanging window and poor closing tightness, which will result in product application limitations. Therefore, it is necessary to develop an opening and closing mechanism that can reduce the deformation error of the transmission mechanism, ensure the synchronous opening and closing control of the long-distance hanging window, and ensure the tight closing of the hanging window
