Description
本發明涉及一種投影儀調節裝置，尤指一種調節投影儀相對於螢幕的俯仰角的調節裝置。 The present invention relates to a projector adjusting device, and more particularly to an adjusting device for adjusting a pitch angle of a projector relative to a screen.
投影儀根據圖像資訊調製從光源發射的光束以形成一光學圖像，並以放大的方式將光學圖像投射到螢幕等上面。通常，投影儀用來在會議、講座及展覽會等中作演示使用。為了更容易和清晰地看到從投影儀投射到螢幕上的光學圖像，必須根據各種使用環境來適當地調整投影儀的俯仰角。 The projector modulates the light beam emitted from the light source based on the image information to form an optical image, and projects the optical image onto the screen or the like in an enlarged manner. Usually, projectors are used for presentations in conferences, lectures, exhibitions, etc. In order to more easily and clearly see the optical image projected from the projector onto the screen, the pitch angle of the projector must be appropriately adjusted according to various usage environments.
目前，常用的俯仰角調整裝置係透過調整投影儀前側相對於其後側的高度位置來調整投影儀的俯仰角。具體地說，這種俯仰角調整裝置設在投影儀前面的中央，並帶有可相對於投影儀的殼體上下伸縮的支座和用來鬆開支座的固定伸縮位置的操作按鈕，該操作按鈕設在投影儀前側的中央並靠近該支座。 At present, the commonly used pitch angle adjusting device adjusts the pitch angle of the projector by adjusting the height position of the front side of the projector relative to the rear side thereof. Specifically, the pitch angle adjusting device is disposed at the center of the front of the projector, and has a support that can be vertically extended and retractable relative to the housing of the projector, and an operation button for loosely fixing the telescopic position of the seat. The operation button is placed in the center of the front side of the projector and is close to the holder.
上述調節裝置在調節的過程中，使用者必須用一隻手支撐住投影儀前側中央，用另一隻手一直按壓操作按鈕，在保持該種狀態的情況下改變投影儀的傾斜度，並在所要求的位置鬆開操作按鈕，操作不方便。採用該種調節方法，很難精確地 調整投影儀的俯仰角度。 In the adjustment process, the user must support the center of the front side of the projector with one hand, and press the operation button with the other hand, and change the inclination of the projector while maintaining the state, and The required position to release the operation button is inconvenient to operate. With this adjustment method, it is difficult to accurately Adjust the pitch angle of the projector.
鑒於以上內容，有必要提供一種可較為精確地調整投影儀俯仰角度的投影儀調節裝置。 In view of the above, it is necessary to provide a projector adjusting device that can adjust the pitch angle of the projector more accurately.
一種用來調節具有一底座的投影儀的俯仰角的投影儀調節裝置，包括一安裝於該底座且可相對於該底座上下活動的支撐軸及一可旋轉地安裝於該底座的旋轉軸，該支撐軸上設有複數齒，該旋轉軸上設有一齒輪，該等齒和該齒輪相嚙合，當旋轉該旋轉軸時，驅使該支撐軸相對該底座上下運動，該底座內固定一定位塊，該定位塊設有一通孔，該旋轉軸的一端為圓桿部，該圓桿部穿過該通孔將該旋轉軸可旋轉地裝設於該底座。 A projector adjusting device for adjusting a pitch angle of a projector having a base, comprising: a support shaft mounted to the base and movable up and down relative to the base; and a rotating shaft rotatably mounted to the base, the rotating shaft The support shaft is provided with a plurality of teeth, and the rotating shaft is provided with a gear, and the gears mesh with the gear. When the rotating shaft is rotated, the support shaft is driven to move up and down relative to the base, and a positioning block is fixed in the base. The positioning block is provided with a through hole, and one end of the rotating shaft is a round rod portion, and the round rod portion passes through the through hole to rotatably mount the rotating shaft to the base.
相較現有技術，該投影儀調節裝置利用該支撐軸的齒與旋轉軸的齒輪相嚙合，旋轉旋轉軸來帶動該支撐軸相對該投影儀運動，從而來調節投影儀的俯仰角，操作簡便且精確。 Compared with the prior art, the projector adjusting device uses the teeth of the supporting shaft to mesh with the gear of the rotating shaft, and rotates the rotating shaft to drive the supporting shaft to move relative to the projector, thereby adjusting the pitch angle of the projector, and the operation is simple and convenient. accurate.
