Embodiment Construction
[0033] Please refer to figure 1 , Figure 2a and Figure 2b , figure 1 It is a three-dimensional schematic diagram when the lens fixing module of the present invention is combined with the projection lens; Figure 2a for figure 1 explosion map; Figure 2b for figure 1 side view. It should be noted that, for the convenience of drawing and description, Figure 2b Only schematic diagrams of some elements are shown in the figure, not all elements are shown. The lens fixing module 200 is used for fixing and installing the projection lens 100. The projection lens 100 is provided with a positioning bump 110. The lens fixing module 200 includes a base 210 and a fixing frame 220. The fixing frame 220 is provided with a first recess corresponding to the positioning bump 110. The groove 221 , the fixing frame 220 is fixed on the base 210 , and a first slit 222 is formed between the base 210 and the fixing frame 220 , and the first slit 222 communicates with the first groove 221 ....

The invention relates to a lens fixing module and a projector using the lens fixing module. A locating protruding block is arranged on a projection lens, the lens fixing module comprises a base and a fixed framework, the fixed framework is provided with a first groove corresponding to the locating protruding block, the fixed framework is fixedly arranged on the base, a first narrow slit is formed between the base and the fixed framework, and the first narrow slit is communicated with the first groove. When the projection lens is assembled, the locating protruding block is inserted into the lens fixing module along the first groove, the projection lens is rotated in a first direction until the locating protruding block is clamped in the first narrow slit, and therefore the projection lens is fixedly arranged in the lens fixing module. When the projection lens is disassembled, the projection lens is rotated in a second direction opposite to the first direction until the locating protruding block leaves the first narrow slit and is located in the first groove, and the projection lens is taken out from the lens fixing module. The lens fixing module uses a rotating clamping mode to enable the projection lens to be rapidly assembled and disassembled, manufacturing cost is lowered, and using convenience is further improved.
Description
technical field [0001] The invention relates to a lens fixing module and a projection device using it, in particular to a lens fixing module and a projection device using the lens fixing module for users to quickly replace projection lenses according to different needs. Background technique [0002] In the current lens fixing module of the prior art, when removing the lens, it is necessary to first press a positioning mechanism to withdraw the positioning pin, and at the same time rotate the lens to remove the lens. It is very inconvenient to use both hands during the disassembly process; Otherwise, more components need to be used, which also results in higher cost. Therefore, designing a high-practicability lens fixing module for quickly assembling and disassembling the projection lens has become the direction of the industry's efforts. Contents of the invention [0003] In order to solve the problem of large number of components and inconvenient assembly and disassembly...
