[0003] In the prior art, high-wall window openers are generally used to open windows. For example, the Chinese utility model patent with application number CN202121483626.4 discloses a hand-cranked inward-opening curved-arm window opener. This type of window opener generally uses a turbine worm gear labor-saving function to transmit the power for opening and closing windows, and at the same time uses the turbine worm gear self-locking function to achieve window locking and positioning after opening.

[0004] The problem with the above patented technology is that the driving rod, which transmits power, only relies on the worm gear at its lower end to achieve self-locking. When the external wind is strong and there are many linked window sashes, the torque acting on the driving rod may cause the driving rod to deform or the worm gear to be damaged.

DETAILED DESCRIPTION

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1As shown, this embodiment discloses a high-altitude multi-window opening device, which mainly includes a driving rod 1, a transmission mechanism 7 and a top locking structure 8.

[0023] Among them, the driving rod 1 is arranged vertically, the driving rod 1 is rotatably connected to multiple shaft seats 2, the shaft seats 2 are fixedly connected to the wall 3, and multiple cranks 4 are fixed on the driving rod 1. The swinging end of the crank 4 is connected to the window sash 6 through the window sash connecting rod 5, and the two ends of the window sash connecting rod 5 are rotatably connected to the crank 4 and the window sash 6 respectively.

[0024] The transmission mechanism 7 is located at the lower end of the driving rod 1. The transmission mechanism 7 includes a shell 701, which is fixed on the wall 3. A turbine 702 and a worm 703 are arranged in the shell 701. The turbine 702 is meshed with the worm 703. The turbine 702 is fixed to the driving rod 1 through a shaft key. The turbine 702 is dynamically connected to the lower end of the driving rod 1. The contact part between the driving rod 1 and the shell 701 is rotationally connected through a bearing. The end of the worm 703 is rotationally connected to the shell 701 through a bearing structure, and one end of the worm 703 is dynamically connected to the driving device 704.

[0025] The top locking structure 8 is located at the upper end of the driving rod 1. The top locking structure 8 includes a plug connector 801 and a plug slot 802 arranged at the top of the driving rod 1. The plug connector 801 is plugged into the plug slot 802, and the plug connector 801 and the plug slot 802 are both polygonal structures of the same shape. The plug connector 801 is slidably connected to the plug socket 803, and the plug socket 803 is fixed on the wall 3. The plug socket 803 is provided with a guide sliding hole with the same cross-sectional shape as the plug connector 801, and the plug connector 801 is slidably connected to the guide sliding hole. A spring 804 is sleeved on the plug connector 801, one end of the spring 804 abuts against the plug socket 803, and the other end abuts against the limit plate 805, and the limit plate 805 is fixed to the upper end of the plug connector 801; a control rope 807 is provided at the lower end of the plug connector 801, and an axially through-hole 806 is provided in the driving rod 1, and the control rope 807 passes through the hole 806 and is connected to a counterweight block 808 arranged below the transmission mechanism 7.

During the rotation process, the driving rod 1 controls the window sash 6 to open or close through the crank 4 and the window sash connecting rod 5. When the window sash 6 is opened or closed, the control rope 807 drives the plug connector 801 to be inserted into the plug slot 802 under the action of the counterweight block 808, thereby realizing the locking of the upper end of the driving rod 1, and the lower end of the driving rod 1 is self-locking with the help of the worm gear. In this way, the two ends of the driving rod 1 are locked, providing a torsion force for the driving rod 1 to prevent its deformation, thereby protecting the worm gear mechanism at the same time.

[0027] The opening device in this embodiment can realize the simultaneous opening of multiple windows. Specifically, it also includes a linkage rod 9, and a plurality of window seats 10 are arranged on one side of the linkage rod 9. One end of the window seat 10 is hinged to the linkage rod 9, and the other end is fixed to the corresponding window sash 6.
