DETAILED DESCRIPTION

[0017] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0018] Example 1

[0019] Combine Figures 1 to 4 The lifting device of a lifting window that is easy to switch the driving mode shown in the figure includes a shell 1, a driving base 2 is installed in the shell 1, a driving box 3 is installed at one end of the driving base 2, the driving box 3 is connected to the steel rope traction guide block 7, and a turbine 11 for driving the steel rope traction guide block 7 is installed in the driving box 3 to make the steel rope traction guide block 7 reciprocate along the length direction of the shell 1. A transmission worm 13 is meshed with the turbine 11, and the transmission worm 13 is installed in the driving box 3 through a bearing 12. One end of the transmission worm 13 extends to the outside of the driving box 3, and the other end is connected to the driving motor 4. The steel rope traction guide block 7 is driven by the turbine 11 in the drive box 3, so that the steel rope traction guide block 7 can move back and forth to lift the doors and windows. At the same time, the turbine 11 also engages the transmission worm 13, so that when the drive motor 4 drives the transmission worm 13 to rotate, the turbine 11 rotates synchronously to realize the electric lifting function. In a specific power-off environment, the transmission worm 13 extending to the outside of the drive box 3 can be twisted manually or with other tools. When the transmission worm 13 rotates, manual or power-off operation can also be achieved. The operating methods are more than the traditional ones, and it is convenient to switch.

[0020] A guide rail is installed on the driving base 2 of this embodiment, and the lower end of the steel rope traction guide block 7 is connected to the guide rail. A transmission screw mounting seat 5 is installed on the end of the guide rail away from the driving box 3. The transmission screw mounting seat 5 is connected to the turbine 11 through a screw rod 6. The steel rope traction guide block 7 is threadedly connected to the screw rod 6. A driving motor 4 is installed on one side of the driving box 3; the screw rod 6 is driven to rotate by the turbine 11, so that the steel rope traction guide block 7 moves back and forth on the screw rod 6, so as to facilitate the traction of the steel rope to lower the doors and windows for lifting and lowering.

[0021] In the above-mentioned lifting device for a lifting window that is easy to switch the driving mode, a first support wheel seat 9 and a second support wheel seat 10 are respectively installed at both ends of the shell 1, a steel rope guide seat 8 is provided between the transmission screw mounting seat 5 and the first support wheel seat 9, and two rope fixing rods 18 are provided on the outside of the steel rope guide seat 8.

[0022] It is worth noting that a ball nut threadedly connected to the screw rod 6 is installed on one side of the steel rope traction guide block 7 of this embodiment. Through the connection between the screw rod 6 and the ball nut, the lifting force is greater and the operation process is quieter and smoother.

[0023] The two rope fixing rods 18 of this embodiment are respectively used to fix one end of the first steel rope 19 and the second steel rope 20, so that the first steel rope 19 is wound around the steel rope traction guide block 7 and the first support wheel seat 9 in sequence, and the second steel rope 20 is wound around the steel rope traction guide block 7 and the second support wheel seat 10 in sequence, so that during the reciprocating movement of the steel rope traction guide block 7, the first steel rope 19 and the second steel rope 20 can be pulled up and down synchronously, with better synchronization and higher safety during the process of pulling doors and windows to move.

[0024] A bead chain disk mounting seat 14 is installed on the outer side of the shell 1 of this embodiment. The bead chain disk mounting seat 14 corresponds to the transmission worm 13. A bead chain disk 15 is installed in the bead chain disk mounting seat 14 through a rotating shaft. One side of the bead chain disk 15 is provided with a socket mounted on the transmission worm 13. A bead chain 16 is wound around the bead chain disk 15, so that the bead chain disk 15 can be rotated by pulling the bead chain 16, thereby driving the transmission worm 13 to rotate, so that the transmission worm 13 drives the turbine 11, so as to realize manual operation of the screw rod 6, thereby driving the doors and windows to rise and fall, without relying on electric drive.

[0025] Example 2

[0026] like Figure 5 As shown, the difference between the second embodiment and the first embodiment is that the transmission worm 13 can be extended to one end outside the drive box 3 to set a square rod, so that the square hole rod can be installed by a hand drill 17, the square hole rod is inserted into the square rod, and the hand drill 17 is used to drive the transmission worm 13 to rotate, thereby realizing the lifting of doors and windows, and it does not rely on the power environment required by the drive motor 4. In a power outage environment, the lifting of doors and windows is faster.

[0027] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
