Of course, in another embodiment, in order to adjust the relative position between the display screen 200 and the projector, the projector is movably disposed on the bottom plate 110, specifically, the projector is slidably mounted on a slide rail disposed on the bottom plate 110, and the length direction of the slide rail is the direction of the projector toward the display screen 200, and further, when the projector is moved along the length direction of the slide rail, the relative position between the display screen 200 and the projector can be also adjusted, thereby improving the user experience.

In a specific embodiment, the bracket 120 includes a ring-shaped plate 121, and two U-shaped brackets 122 disposed on an end of the ring-shaped plate 121 away from the bottom plate 110, wherein the two U-shaped brackets 122 enclose the groove 101. Through setting up support 120 as annular panel 121 and U type frame 122, can practice thrift the material of support 120 greatly, reduction in production cost.

Preferably, the annular plate 121 is integrally formed with the U-shaped frame 122, but may be welded.

In a specific embodiment, the movable projection apparatus further includes an acrylic plate covered on the bracket 120 and/or the bottom plate 110, specifically, the acrylic plate covers one end of the annular plate 121, and the bottom plate 110 is also provided with the acrylic plate on which the projector is mounted.

Specifically, two handles 111 are disposed on a side of the bottom plate 110 facing the bracket 120, so as to facilitate carrying of the support base 100, and an acrylic plate for placing a projector is disposed on the two handles 111.

In order to fix the display screen 200 more stably, in an embodiment, the removable projection device further includes a clamping bar 500, the clamping bar 500 is mounted on the groove 101 and is used for limiting the display screen 200 in the groove 101, and the display screen 200 is more stably limited in the groove 101 by the clamping bar 500, so that the display screen 200 is not easy to fall off or is cheap when being adjusted.

In one specific embodiment, the clamping strip 500 is fixedly connected to the bracket 120 by a screw thread, such as by fixing the clamping strip 500 to the bracket 120 by a screw and a nut.

The specific shape of the card strip 500 is not limited, preferably, the card strip 500 is a long strip, a card slot 501 is formed on one side of the card strip 500 facing away from the support base 100, and the display screen 200 is installed in the card slot 501. In this embodiment, can be at first through installing display screen 200 in draw-in groove 501, then install card strip 500 and display screen 200 in recess 101, the user need not directly to install display screen 200 on support 120, and then the more convenient to user's assembly, and user experience is better.

In order to prevent the condition of colliding with between the inner wall of display screen 200 and draw-in groove 501, in a specific embodiment, this movable projection equipment still includes film 600, this film 600 pastes and establishes on the both sides wall of draw-in groove 501, and then display screen 200 need not the direct contact to the inside wall of draw-in groove 501, but with the contact of film 600, because film 600 has certain flexibility, so, when display screen 200 is installed in draw-in groove 501, the phenomenon of colliding with can not appear with draw-in groove 501, and then can prevent to damage display screen 200.

Of course, other flexible sheet-like objects can be used instead of the film 600.

In a specific embodiment, in order to facilitate the user to install and detach the display screen 200, the embodiment further includes a fixing baffle 710 and a locking structure 720, the fixing baffle 710 is inserted into the slot 501 and located between the inner side wall of the slot 501 and the display screen 200, and the locking structure 720 enables the fixing baffle 710 to be pressed on the display screen 200, so as to stably fix the display screen 200 on the card strip 500.

Further, the locking structure 720 includes a locking nut 721 hidden in the clamping bar 500 and a locking bolt 722 matched with the locking nut 721, and the locking bolt 722 is screwed on the nut and can pass through the nut to abut on the fixing baffle 710. In this embodiment, the locking bolt 722 is rotated to move relative to the locking nut 721, so as to adjust the force applied by the locking nut 721 on the fixing baffle 710, and further press the display screen 200 in the card slot 501 through the fixing baffle 710.

Further, the number of the locking structures 720 is at least two, and the adjacent locking structures 720 are arranged at intervals to apply pressure at different positions of the fixing baffle 710, so that the pressure is uniformly applied to a plurality of positions of the display screen 200, and the fixing is more stable.

To solve the problem that when the display screen 200 is mounted on the bracket 120, the end of the base plate 110 where the bracket 120 is mounted is pressed more than the end where the projector is mounted, and the movable projection apparatus may topple over, in one embodiment, the movable projection apparatus further includes a weight block (not shown), and a mounting portion (not shown) is disposed on the end of the base plate 110 away from the bracket 120, and the weight block is detachably mounted on the mounting portion. The counterweight block can prevent the bottom plate 110 from overturning towards one end of the display screen 200, so that the use is safer.

It should be noted that, because the balancing weight is detachably arranged on the installation part, the user can change the weight of the balancing weight according to the requirement, and the user experience is better. The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
