[0032] See also Figures 1 to 3 The present invention provides a push rod structure rotation device for a launch platform, comprising a housing 1, a load turntable 2, a drive motor 3, a screw 4, a nut 5, and a drive control box 6. The load turntable 2 is rotatably mounted on the housing 1, an adjustment arm 22 being provided at the edge of the load turntable 2, and the launch platform is mounted on the load turntable 2; the drive motor 3 is disposed within the housing 1; one end of the screw 4 is connected to the rotating shaft of the drive motor 3 via a universal joint 9; the nut 5 is threadedly engaged with the screw 4, and the nut 5 is connected to the adjustment arm 22; the drive control box 6 is disposed within the housing 1, and is electrically connected to the drive motor 3.

[0033] The launch platform push rod structure rotation device provided in this embodiment controls the operation of the drive motor 3 by using the drive control box 6. The drive motor 3 drives the screw rod 4 to rotate, so that the nut 5 on the screw rod 4 moves along the length direction of the screw rod 4, thereby driving the adjustment swing arm 22 connected to the nut 5 to rotate (because the screw rod 4 is connected to the rotating shaft of the drive motor 3 through the universal joint 9, so that the screw rod 4 can swing around the point connected to the rotating shaft, that is, the inclination angle of the screw rod 4 can be changed, thereby cooperating with the rotation of the adjustment swing arm 22, such as Figure 3 The path shown by the dotted line) causes the load turntable 2 to rotate, adjusts the angle of the load turntable 2, and further adjusts the angle of the external mechanism (such as the launching platform and other structures) installed on the load turntable 2.

[0034] In one embodiment, the drive control box 6 is provided with a socket 7 for connecting to an external control circuit.

Figure 2 As shown, when it is necessary to lock the load turntable 2 in the zero position, it is only necessary to loosen the top screw structure 84 and push the lock pin 82 toward the load turntable 2 so that the front end of the lock pin 82 is inserted into the open groove 21 of the load turntable 2, and then tighten the top screw structure 84 to fix the lock pin 82. The lock pin 82 can then be used to lock the load turntable 2, so that the load turntable 2 remains in the zero position (as shown in FIG. Figure 1 The crossbar 83 facilitates the operator to push and pull the locking pin 82, making it easier to lock or unlock the load turntable 2.
