Problems solved by technology

[0003] Currently, there are mainly three types of opening and closing devices: 1. The one-way bending chain is commonly used in the market to drive, and the one-way bending characteristic of the one-way bending chain is used to realize the compound rotation action. The advantages of this scheme are obvious: the thrust is relatively Large, smooth movement, but the defects are also obvious: complex structure, slow opening and closing speed, loud noise, high power consumption
2. For example, the shaft-type window opening devices disclosed in patent Nos. 03115180.9 and 97212819.0 install arc-shaped racks through the shaft or shaft running through the hinge, and the shaft is driven by power to open and close the fan. In fact, it is difficult to realize—— It is difficult to achieve the torque required for opening and closing

specific Embodiment approach 1

[0023] Specific implementation mode one: refer to Figure 1-Figure 3 , the specific embodiment adopts the following technical scheme: it includes the first active link 1, the second active link 2, the first passive link 3, the second passive link 4, the first kinematic pair 5 and the second kinematic pair 6. The first active link 1, the second active link 2, the first passive link 3, and the second passive link 4 are hinged together end to end to form a strut, and the first kinematic pair 5 and the second kinematic pair 6 are respectively Installed on the extension section outside the hinge point of the first active link 1 and the second active link 2, the connecting piece 7 is located at the hinge point of the first passive link 3 and the second passive link 4, and is reliably connected with the window sash.

[0024] The first active link 1 , the second active link 2 , the first passive link 3 , and the second passive link 4 can be of the same length or not.

[0025] The fir...

specific Embodiment approach 2

[0033] Specific implementation mode two: refer to Figure 4 The difference between this embodiment and Embodiment 1 is that: after the first passive link 3 and the second passive link 4 extend out of the hinge point, they are connected with the first extension link 31 and the second extension link The rods 41 are hinged to form a composite hinge, and the connectors are installed on the hinge points of the first extension link 31 and the second extension link 41 . Other components and connections are the same as those in the first embodiment.

[0034] This specific implementation and specific implementation can increase the opening distance and reduce the opening and closing torque.

specific Embodiment approach 3

[0035] Specific implementation mode three: refer to Figure 5 The difference between this embodiment and the first embodiment is that an energy storage device 11 is installed between the hinge points of the connecting rods, and the other components and connections are the same as those of the first embodiment.

[0036] The energy storage device 11 is a tension spring.

[0037] The principle of this specific implementation is: when the sash 92 is closed, the energy storage device 11 is gradually stretched; when the sash 92 is completely closed, the energy storage device 11 is stretched to the maximum, and the potential energy also reaches the maximum; The energy storage device 11 shrinks, releases the stored potential energy and converts it into the thrust of the connecting rod, which greatly reduces the load when the motor is started. Such as Figure 5 The connection method shown is particularly effective when applied to top-hung windows, and is especially effective when app...

Abstract

The invention discloses a connecting-rod opening and closing mechanism used for casement doors and windows and suspended sash windows and relates to the technical field of a door-window opening and closing mechanism. A stay bar comprises four connecting rods which are hinged successively from the head to the tail, wherein kinematic pairs are arranged on two active connecting rods to be convenient for receiving power to drive the connecting rods. By utilizing the instability of quadrangles, the two active connecting rods equipped with the kinematic pairs drive the other two passive connecting rods to move synchronously to open and close a window sash connected with the stay bar while being driven by power. Compared with the prior art, the connecting-rod opening and closing mechanism disclosed by the invention skillfully transforms the movements of translation or rotation of a transmission mechanism to the movements of translation and rotation for opening and closing the casement doors and windows and the suspended sash windows. The connecting-rod opening and closing mechanism has the characteristics of simple structure, reliable performance, large opening and closing force, low motor power consumption, no movement dead point limitation, low noise, large push force and rapid and stable opening and closing speeds.

Description

Technical field: [0001] The invention relates to the technical field of door and window opening and closing mechanisms, in particular to a connecting rod opening and closing mechanism for casement doors and windows and hanging windows, in particular to a connecting rod opening and closing mechanism for electric, automatic or intelligent control of casement doors and windows / hung windows mechanism. Background technique: [0002] Electric, automatic or intelligent control of the opening and closing of casement doors and windows and hanging windows, the movement of fans is relatively simple, but it is more complicated for the opening and closing device to realize this action. The motion of the door and window is a simple rotary motion, but the opening and closing device needs to complete the compound rotary motion in order to realize the simple rotary motion of the door and window. [0003] Currently, there are mainly three types of opening and closing devices: 1. The one-way ...
