According to the stabilizing device in the lifting adjusting projector, the lifting adjusting projector comprises a table, a projection lamp is arranged on the table, and a first table leg, a second table leg, a third table leg and a fourth table leg are arranged on the lower surface of the table. The stabilizing device comprises a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod, and further comprises a fifth connecting rod, a sixth connecting rod, a seventh connecting rod and an eighth connecting rod. The stabilizing device in the lifting adjusting projector has the advantages that the projection lamp can be adjusted in a lifted mode.

Description

technical field [0001] The invention belongs to the technical field, and relates to a projector, in particular to a stabilizing device in a projector that can be adjusted up and down. Background technique [0002] At present, projectors are used to provide visual information for the crowd. With the development of electronic technology, projectors are becoming smaller and smaller and easier to carry. Because the projector lens is relatively fragile, it is easy to be damaged when carried, and a corresponding protective structure is needed. to protect the lens. In addition, when the projector projects visual information, it is necessary to adjust the projection angle according to the actual situation of the broadcasting site. Generally, after the projector is set up on the projector bracket, it is difficult to adjust the projection angle of the projector lens according to the needs. Fine-tuned properly, and the projector must also be placed on a level table. [0003] Due to t...
