Detailed Description

Example 1

As shown in fig. 1-3, the greenhouse framework for breeding high seedlings of 4.5 meters is consistent with the structure of the traditional greenhouse framework, the greenhouse framework in the scheme comprises a main upright post 1, auxiliary upright posts 2 and a ceiling frame 3, the main upright posts are connected to the middle of the ceiling frame, the auxiliary upright posts are connected to two sides of the ceiling frame, the ceiling frame is arched, and the total height of the greenhouse framework is about 4.5 meters. The improved structure is that the main upright post 1 comprises an upper supporting rod 101 and a lower supporting rod 102, the upper supporting rod and the lower supporting rod are sleeved with a middle supporting rod 103, the end parts of the supporting rod and the lower supporting rod are symmetrically hinged with two auxiliary connecting rods 104, each auxiliary connecting rod is formed by hinging two sections of supporting rods, the two sections of supporting rods are hinged with each other through a hinging seat 105, the hinging seats and the middle supporting rod are provided with bolt holes, and connecting bolts 106 are arranged in the bolt holes; the auxiliary upright post is a scissor-fork type structure formed by rotationally connecting two single support rods 201; the ceiling frame is formed by connecting an arch bar 301 and a cross bar 303, a plurality of stress rods 302 which are distributed in a triangular shape are connected between the arch bar 301 and the cross bar 303, a main upright post is connected to the middle part of the arch bar, auxiliary upright posts are connected to the two ends of a cross connecting rod, and the auxiliary upright posts are hinged with the cross connecting rod.

According to the scheme, the greenhouse framework is not provided with two roof frames which are connected into a group, and the auxiliary upright posts of the two roof frames are hinged with each other to form the scissor-fork type structure. In this scheme, main column and vice stand all adopt the structure that can contract.
