[0030] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the utility model.
[0031] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating orientation or positional relationships are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the utility model.
[0032] Please refer to Figures 1 - 8As shown in the figure, the utility model relates to a portable projector EPP packaging device, which includes a device body 1. Inside the device body 1, there is a projector 2. A fixing component 3 is slidably installed in the inner cavity of the device body 1. A power component 4 is threadedly installed in the middle of the fixing component 3. At one end of the power component 4, a restoring component 5 is symmetrically and fixedly installed. The restoring component 5 is elastically installed between the device body 1. At one end of the device body 1 and on one side of the projector 2, a cleaning component 6 is rotatably installed.
[0033] During use, first place the projector 2 into the inner cavity of the device body 1. When the projector 2 contacts the power component 4 and pushes the power component 4 to move towards the end away from the projector 2, then the movement of the power component 4 will drive the threadedly installed fixing component 3 to move. Then, both ends of the fixing component 3 will move towards the two side walls of the projector 2, thereby limiting the projector 2 to prevent the projector 2 from shifting during transportation. The movement of the power component 4 will compress its elastic property. When the projector 2 is limited, at this time, the cleaning component 6 will contact the lens of the projector 2. Then, drive the cleaning component 6 to rotate by hand. Subsequently, the rotation of the cleaning component 6 will clean the lens of the projector 2 and the periphery of its lens, thereby cleaning the lens of the dust projector 2. After the projector 2 is limited, the device body 1 can be closed.
[0034] Thus, the projector 2 is used to push the power component 4 to move. Subsequently, the power component 4 will drive both ends of the fixing component 3 to move towards the two side walls of the projector 2 at the same time, thereby limiting the projector 2 and avoiding the phenomenon that the projector 2 is damaged when it is impacted by external forces during transportation.
[0035] Thus, after the projector 2 is limited, rotate the cleaning component 6 by hand to clean the lens of the projector 2 and the periphery of its lens, so as to clean the lens of the projector 2 and avoid the situation that the projected image is not clear when using the projector 2 next time.
[0036] In addition, during specific application, the part in contact with and limiting the projector 2 is preferably made of EPP material, that is, the EPP material has significant advantages such as light weight, high strength, good cushioning performance, environmental protection and recyclability.
[0037] In one embodiment, for the above-mentioned device body 1, the device body 1 includes a housing 101. A handle 102 is rotatably installed at one end of the housing 101. A housing cover 103 is rotatably installed at one end of the housing 101.
[0038] In use, the handle 102 can be lifted by hand to drive the outer shell 101 to move. When the projector 2 is fixed, the outer shell cover 103 can be rotated by hand to close the outer shell 101.
[0039] In one embodiment, for the above-mentioned fixing component 3, the fixing component 3 includes a fixing gear 301. One end of the fixing gear 301 is rotatably installed with a support rod 302, and the support rod 302 is fixedly installed with the outer shell 101. Two gear racks 303 are symmetrically engaged at both ends of the fixing gear 301.
[0040] The two gear racks 303 are fixedly installed with EPP material plates 304 at the mutually remote ends. The EPP material plates 304 are slidably installed on the outer shell 101, and sliding grooves 104 for slidably installing the two EPP material plates 304 are formed on the outer shell 101.
[0041] The power component 4 includes a threaded rod 401. The threaded rod 401 is threadedly installed on the fixing gear 301, and a moving plate 402 is fixedly installed at one end of the threaded rod 401.
[0042] In use, first, the projector 2 is placed into the inner cavity of the outer shell 101. When the projector 2 contacts the moving plate 402, then the projector 2 pushes the moving plate 402 on one side to move. Subsequently, the movement of the moving plate 402 will drive the fixedly installed threaded rod 401 to move. Then the threaded rod 401 will drive the fixing gear 301 installed by threading to rotate under the support of the support rod 302. Then the fixing gear 301 will drive the two gear racks 303 engaged at both ends to move simultaneously. Then the two gear racks 303 will move closer to each other simultaneously. Then the two gear racks 303 will drive the EPP material plates 304 fixedly installed on them to slide on the sliding grooves 104. Then the two sliding EPP material plates 304 will limit the two ends of the projector 2, thereby avoiding the phenomenon that the projector 2 is damaged when it is impacted by an external force during transportation.
[0043] In one embodiment, for the above-mentioned restoring component 5, the restoring component 5 includes a sliding rod 501. The sliding rod 501 is fixedly installed on the moving plate 402, a spring 502 is sleeved on the circumferential surface of the sliding rod 501, and a connecting frame 503 is slidably installed on the circumferential surface of the sliding rod 501.
[0044] The connecting frame 503 is fixedly installed on the outer shell 101. One end of the spring 502 abuts against the moving plate 402 and the other end abuts against the connecting frame 503.
[0045] The movement of the moving plate 402 will drive one end of the sliding rod 501 to move. Since one end of the spring 502 abuts against the moving plate 402 and the other end abuts against the sliding rod 501, and the connecting frame 503 is fixedly installed on the housing 101, the movement of the moving plate 402 will drive the spring 502 to be compressed. When the projector 2 is in use, the compressed spring 502 will push the moving plate 402 to reset, so that the moving plate 402 returns to its initial position for the next limit of the projector 2.
[0046] In one embodiment, for the cleaning component 6 described above, the cleaning component 6 includes a rotating shaft 601, the rotating shaft 601 is rotatably installed on the housing 101, a rotating block 602 is fixedly installed at one end of the housing 101, and a cleaning block 603 is fixedly installed at the other end of the rotating shaft 601.
[0047] After the projector 2 is limited, the lens of the projector 2 will come into contact with the cleaning block 603 at this time. Then, turn the rotating block 602 by hand. Subsequently, the rotating block 602 drives the fixedly installed rotating shaft 601 to rotate, the rotating shaft 601 drives the fixedly installed cleaning block 603 to rotate, and then the rotating cleaning block 603 can clean the lens of the projector 2 and its periphery, preventing the projection screen from being unclear when the projector 2 is used next time.
