Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of opening and closing device of fruit and vegetable greenhouses top layer, packet
Frame 1 is included, 1 upper end of frame is fixedly connected with crossbeam 2, fluted 3 is opened up inside crossbeam 2,2 upper end of crossbeam is fixedly connected with extension
Bar 4 is fixedly connected with guide rod 5 inside extension rod 4, curved rod 6 is fixedly connected on the outside of crossbeam 2, and 6 lower end of curved rod is fixed
It is connected with stringer 7, telescopic rod 8 is rotatably connected on the outside of stringer 7,8 upper end of telescopic rod is fixedly connected with shell 9, lives inside groove 3
It is dynamic to be connected with stock 10, and stock 10 is fixedly connected with 11 He of gear between curved rod 6 and guide rod 5 on the outside of stock 10
