Problems solved by technology
Such a cumbersome adjustment process will increase the inconvenience of using the projection device, and if the adjustment is not done properly, it will often cause the projection image to be skewed
[0004] On the other hand, for a fixed projection device, it is necessary to adjust the position of the projected image in advance when erecting, so that the projected image can be matched with the screen. The location needs to be considered in advance. Once the installation is completed, it is very difficult to adjust the projected image, resulting in increased restrictions on the use of projection devices

Embodiment Construction
[0032] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.
[0033] Certain terms are used in the description and claims to refer to particular elements. Those of ordinary skill in the art will appreciate that manufacturers may refer to the same element by different terms. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Include" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to".
[0034] refer to Figure 1 to Figure 5 As shown, a schematic structural diagram of the lens adjustment module 100 of the present invention is disclosed. in, figure 1 is a side view of the lens adjustment module 100 according to the first...

The invention provides a lens adjusting module group and a protection device. The lens adjusting module group comprises a pedestal, a supporting member, a guide unit and a slide block. The supporting member is provided with first fixing parts. Each first fixing part is provided with a first through hole which is arranged along a first axial direction. The guide unit is arranged on the pedestal along the first axial direction, and the guide unit penetrates through the first through hole. The slide block is provided with a second through and a groove which are communicated. The second through hole is arranged along the first axial direction and used for penetrating arrangement of the guide unit. The groove is used for completely accommodating the first fixing parts, and the groove extends along a second axial direction so as to provide a dodging space for the first fixing parts to move along the second axial direction relative to the slide block. The supporting member can move along the first axial direction and the second axial direction relative to the guide unit and the pedestal so as to adjust the supporting member in two axial directions.
Description
technical field [0001] The invention relates to the field of projection devices, in particular to a lens adjustment module and a projection device with the lens adjustment module. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can communicate with computers, Video Compact Discs (VCD), Digital Video Disks (DVDs) through different interfaces. ), Blu-ray Disc (Blu-ray Disc, BD), game console, digital video camera (Digital Video, DV), etc. are connected to play corresponding video signals. Projectors are widely used in homes, offices, schools and entertainment venues. [0003] During the projection process, the adjustment of the projection lens directly affects the quality of the projection effect. However, in the existing non-fixed projection device, when adjusting, the horizontal position of the image needs to be adjusted by moving the hand, and at the same time, the vertical height of the...
