Problems solved by technology

However, since this type of locking device is usually installed to prevent the lens cover 10 from falling off without reason, the user must first apply a certain degree of force to release the locking effect before the lens cover can be removed.
Therefore, not only is it easy to cause inconvenience in use, but also the way of connecting the lens cover 10 to the casing of the projector 100 with the line segment 11 also affects the overall appearance of the projector.
In addition, when the projector 100 is booting up, if the user mistakenly covers the lens opening 101 with the lens cap 10, the strong light from the projector 100 will directly irradiate the lens cap 10, thus causing the lens cap to melt.

Embodiment Construction

[0013] refer to figure 2 and image 3 , the sliding lens cover 1 of the present invention is installed on a projector 100, and a lens opening 101 of the projector 100 of the present embodiment is formed on the front left side of the casing, and the function of the sliding lens cover 1 is to close or open This lens opening 101, and due to the inner peripheral edge of the housing that defines the lens opening 101, a substantially elliptical fixed plate portion 102 extends from the right side of the lens opening 101, so that the lens opening 101 is not a complete circle shaped opening, and a notch groove 103 is formed on the top of the fixing plate portion 102 and communicates with the lens opening 101 in the transverse direction.

[0014] A preferred embodiment of the sliding lens cover 1 includes a sliding cover 2 , a fixing part 3 , a locking part 4 , a switch element 5 and an outer cover 6 .

[0015] The sliding cover plate 2 is a circular plate, which has a front 201, a b...

Abstract

The present invention relates to a slide lens cap which can be used for closing or opening lens opening of a projector. It includes a slide cap plate and a fixing piece. On the slide cap plate at least a slide groove is formed, said slide groove has first end and second end. Said fixing piece has a first fixing portion which can be passed through said slide groove and fixed on the projector and a restraining portion placed against said slide cap plate for making the slide cap plate be fixed on the projector. Besides, said invention also provides its concrete operation method.

Description

technical field [0001] The invention relates to a lens cover, in particular to a sliding lens cover. Background technique [0002] refer to figure 1 , the existing lens cover 10 used to cover the lens opening 101 of the projector 100 is to avoid inadvertent loss after being removed. Usually, it is connected to the shell of the projector 100 with a line segment 11. When the projector 100 is in use, the lens cover 10 is removed, and the line segment 11 is used to hang the shell of the projector 100. After the projector 100 is used, the Cover the lens cover 10 and cover the lens opening 101, and in order to prevent the lens cover 10 from falling off without reason, the lens cover 10 is also provided with a catch that can be engaged in the inner periphery of the lens opening 101 in the housing of the projector 100 device (not shown). However, since this type of locking device is usually installed to prevent the lens cover 10 from falling off without reason, the user must firs...
