[0002] The support rod system of the bottom cage door frame of the adjustable angle construction elevator is mainly used to support the bottom cage door frame. It mainly connects the guide frame and the bottom cage door frame through the support system to make the door frame stable and reliable. At present, the main adjustable angle construction elevator bottom cage adjustment rods on the market are fixed, and the angle and length cannot be adjusted. Its main feature is that it is welded and formed according to different angles. Different angles require different support systems. This support system can ensure the stability of the door frame, such as Figure 4 shown.

[0003] Due to the different angles required for buildings with different inclination angles, the bottom cage door adjustment rod will be remade according to the different angles of the guide rail frame, which not only causes a waste of equipment, but also increases the construction cost by investing a lot of manpower and material resources. At the same time, there are also the following problems: 1. The existing bottom cage door adjustment rod is fixed and cannot be adjusted in angle and length. For guide rail frames with different angles, bottom cage door adjustment rods with different angles need to be customized, resulting in poor applicability; 2. Due to the different angles of buildings, the angle of the guide rail frame will change, which will cause the length and angle of the bottom cage door adjustment rod to change, resulting in the existing bottom cage door support rod cannot fully meet its needs. Various different angles also require special production of bottom cage door adjustment rods, which brings great inconvenience to technology, production, installation and use; 3. Due to the large number of existing fixed bottom cage door adjustment rods, various molds need to be constantly changed during the production process, resulting in the difficulty in guaranteeing the key angle dimensions.
