Embodiment
[0030] as attached figure 1 to attach Figure 4 Shown:
[0031] The invention provides an aircraft ejection frame for teaching competitions, which includes a ejection frame base, a ejection frame bracket and an ejection platform. The setting of code 17 makes the installation beams 1 detachable, and can also be vertically connected to each other;
[0032] The ejection rack support includes a plurality of support blocks 3 arranged on the vertical installation beam 1, and a plurality of support blocks 3 are provided with ejection tracks 2 corresponding to the vertical installation beam 1, and a plurality of support blocks 3 can be installed overlapping each other, The support block 3 can support the ejection rail 2, and the overlapping of a plurality of support blocks 3 can adjust the distance between the ejection rail 2 and the installation beam 1, so that the ejection rail 2 is at a different and easy-to-calculate height;
[0033] The ejection platform includes a placement p...

The invention provides an aircraft catapulting frame for a teaching competition, belongs to the technical field of teaching model airplanes, and aims to solve the problem that the performance of model airplanes manufactured by students cannot be fairly displayed in the model airplane competition, the aircraft catapulting frame comprises a catapulting frame base, a catapulting frame support and a catapulting platform, the catapulting frame base comprises mounting beams, and the two mounting beams are connected into a T-shaped frame through a corner connector; the ejection frame support comprises a plurality of supporting blocks arranged on a vertical installation beam, an ejection rail is arranged on the supporting blocks, the ejection platform comprises a placing plate arranged on the ejection rail, an ejection end is arranged at the rear end of the ejection rail, the two sides of the ejection end are connected with first pulleys, the two sides of the supporting blocks are provided with second pulleys, and the second pulleys are connected with the ejection end. The rear end of the placing plate is connected with a mounting beam transversely arranged on the T-shaped frame through two elastic ropes, and the middle parts of the elastic ropes are sequentially wound on the first pulley and the second pulley; and a locking mechanism for fixing the position of the placing plate is arranged on the vertical mounting beam positioned at the foremost end.
Description
technical field [0001] The invention belongs to the technical field of teaching model airplanes, and more specifically relates to an aircraft ejection frame for teaching competitions. Background technique [0002] Airplane models are very popular among children. Children throw model airplanes with their hands, and their hands will become sore after a long time. Children will lose interest in model airplanes if their hands are sore for a long time. Using rubber bands to eject airplanes has a high risk factor and is easy to hurt hands. It is the eyes of children. [0003] In addition, due to the different hand-making abilities of the students, there are also differences in the production of the same model airplane. Hand throwing and rubber band ejection cannot intuitively reflect the children's hand-making ability. In the model airplane competition, if the same model airplane is thrown by hand or ejected by a rubber band, due to the different operating abilities of the studen...
