Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, but the embodiments of the present invention are not limited thereto.

Through structural analysis of the optical machine 5 of the projector, the structural parts of the whole projector have manufacturing errors, installation errors inevitably exist when the optical machine is assembled on the whole projector, the installation errors cause the phenomenon that the left side and the right side of the optical machine 5 are unbalanced, meanwhile, the projection picture of the optical machine 5 also has an inclination phenomenon, and the two factors are accumulated to cause the projection picture of the whole projector to incline left and right, so that the installation of the optical machine 5 needs to be leveled during assembly.

Example 1:

referring to fig. 1-3, a leveling structure comprises a screw post 1, an adjusting spring 2, a fastening bracket 3 and a fastening screw 4, wherein the fastening bracket 3 is used for being mounted on an optical machine 5 of a projector, the adjusting spring 2 is located between the fastening bracket 3 and the screw post 1, and the fastening screw 4 is connected to the screw post 1 after passing through a through hole or a threaded hole on the fastening bracket 3 and the adjusting spring 2.

When the leveling structure is used, the fastening supports 3 of the leveling structures are arranged around the optical machine 5 of the projector, so that the optical machine 5 of the projector is erected on the leveling structure, and when the optical machine 5 of the projector is leveled, the fastening screws 4 are only required to be adjusted, and then the adjusting springs 2 are compressed to achieve leveling.

It should be noted that the leveling structure of the present embodiment is not limited to leveling the light engine 5 of the projector in the present embodiment.

In some embodiments, the adjusting end of the fastening screw 4 has a hexagonal counter bore, which can be adjusted by a user using a hexagonal wrench.

In other embodiments, the adjusting end of the fastening screw 4 has a rotating handle thereon, so that it can be leveled by manual rotation.

Example 2

A projector comprises an optical machine and leveling structures in an embodiment 1, wherein a plurality of fastening supports of the leveling structures are arranged around an optical machine 5, the optical machine is erected on the leveling structures, and the leveling is realized by adjusting fastening screws 4 and further compressing an adjusting spring 2.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
