Description

Technical Field

[0001] This utility model relates to the field of digital display technology of land and resources, and in particular to a platform projection device. Background Technology

[0002] Digital display of land and resources refers to the use of modern information technology to digitally display and manage various information about land and resources (such as land use, mineral resources, and water resources). This digital display requires projection equipment to project onto a screen. Currently, when projection equipment operates continuously, the bulb generates significant heat, and the built-in projector power supply also produces considerable heat. Typical projectors use simple cooling fans for heat dissipation, but when projection time is prolonged, the cooling fan's capacity becomes insufficient, causing the internal temperature components of the projector to rise and shortening its lifespan.

[0003] The prior art patent application CN 220290016 U discloses a projector device, including a housing, a projection component, a semiconductor cooling chip, and a second heat sink. The semiconductor cooling chip generates a low temperature on its lower side and transfers it to the second heat sink, which in turn lowers the temperature of the surrounding air. Then, a second cooling fan blows the low temperature to various parts of the housing, allowing the high-temperature air inside the housing to be expelled, thereby better cooling the projection component and effectively extending its service life.

[0004] The structure and materials of projection components are often quite fragile. However, in the existing technology, when the device is not in operation, the projection components are exposed to the outside world and are easily damaged, resulting in low practicality of the device. Utility Model Content

[0005] The purpose of this invention is to provide a platform projection device that addresses the problem that the structure and materials of projection components are often fragile, and in the prior art, when the device is not in operation, the projection components are exposed to the outside world and are easily damaged, resulting in low practicality of the device.

[0006] To achieve the above objectives, this utility model provides a platform projection device, including a housing, a projection component, and a protective mechanism. The protective mechanism includes a protective cover, a sliding component, a movable plate, a fixed frame, two fixed components, and a baffle. The projection component is disposed at one end of the housing, and the protective cover is disposed at one end of the housing. The sliding component is disposed on the protective cover and the housing, and the protective cover is slidably connected to the housing via the sliding component. The movable plate is fixedly connected to the protective cover and is located above the protective cover. The fixed frame is fixedly connected to the housing, and the movable plate is slidably connected to the fixed frame and is located within the fixed frame. The two fixed components are respectively disposed at both ends of the fixed frame, and the baffle is fixedly connected to the housing and is located at the end of the housing away from the protective cover.

[0007] The sliding assembly includes a slide rail and three rotating components. The slide rail is fixedly connected to the housing and located below the protective cover, and the three rotating components are located below the protective cover.

[0008] The rotating assembly includes a support frame, a rotating roller, and a pulley. The support frame is fixedly connected to the protective cover and is located below the protective cover. The rotating roller is rotatably connected to the support frame and the pulley, and the pulley is located inside the support frame.

[0009] The fixing component includes a limiting rod and a telescopic kit. The movable plate has a slot. The limiting rod is slidably connected to one end of the fixing frame. One end of the limiting rod extends into the slot. The telescopic kit is disposed between the limiting rod and the fixing frame.

[0010] The telescopic kit includes a telescopic spring and a movable block. The movable block is fixedly connected to the limiting rod. Both ends of the telescopic spring are fixedly connected to the movable block and the fixed frame, respectively, and the limiting rod is located inside the telescopic spring.

[0011] This utility model discloses a platform projection device. When the projection component is working, the protective cover is located on one side of the projection component and will not interfere with the operation of the projection component. After the projection component is used, the protective cover is slid onto the projection component via the sliding component. The moving plate slides within the fixed frame to ensure that the protective cover does not tilt or misalign until the protective cover is in contact with the baffle. Then, the fixing component fixes the moving plate and the protective cover to ensure that the protective cover does not slide. The protective cover and the baffle enclose the projection component, protecting it from external damage and thus improving the practicality of the device. Attached Figure Description

[0019] This utility model provides a platform projection device, including a housing 101, a projection component 102, and a protective mechanism. The protective mechanism includes a protective cover 103, a sliding component, a moving plate 105, a fixed frame 110, two fixed components, and a baffle 104. The sliding component includes a slide rail 114 and three rotating components. The rotating components include a support frame 107, a rotating roller 108, and a pulley 109. The fixed components include a limiting rod 111 and a telescopic component. The moving plate 105 has a slot 106. The telescopic component includes a telescopic spring 113 and a moving block 112. The aforementioned solution solves the problem that the structure and material of the projection component 102 are often relatively fragile. However, in the prior art, when the device is not in operation, the projection component 102 is exposed to the outside world and is easily damaged, resulting in low practicality of the device.

[0020] In this embodiment, the projection component 102 is disposed at one end of the housing 101, the protective cover 103 is disposed at one end of the housing 101, the sliding component is disposed on the protective cover 103 and the housing 101, the protective cover 103 is slidably connected to the housing 101 via the sliding component, the moving plate 105 is fixedly connected to the protective cover 103 and is located above the protective cover 103, the fixing frame 110 is fixedly connected to the housing 101, the moving plate 105 is slidably connected to the fixing frame 110 and is located inside the fixing frame 110, two fixing components are respectively disposed at both ends of the fixing frame 110, and the baffle 104 is fixedly connected to the housing 101 and is located at the end of the housing 101 away from the protective cover 103. When the projection component... When the projection assembly 102 is in operation, the protective cover 103 is located on one side of the projection assembly 102 and will not interfere with the operation of the projection assembly 102. After the projection assembly 102 is used, the protective cover 103 is slid onto the projection assembly 102 via the sliding component. The moving plate 105 slides within the fixed frame 110 to ensure that the protective cover 103 does not tilt or misalign until the protective cover 103 is in contact with the baffle 104. Then, the moving plate 105 and the protective cover 103 are fixed by the fixing component to ensure that the protective cover 103 does not slide. The protective cover 103 and the baffle 104 enclose the projection assembly 102, protecting the projection assembly 102 from external damage, thereby improving the practicality of the device.

[0021] Furthermore, the slide rail 114 is fixedly connected to the housing 101 and is located below the protective cover 103, and the three rotating components are disposed below the protective cover 103.

[0022] Furthermore, the support frame 107 is fixedly connected to the protective cover 103 and is located below the protective cover 103. The rotating roller 108 is rotatably connected to the support frame 107 and the pulley 109, and the pulley 109 is located inside the support frame 107.

[0023] In this embodiment, when the protective cover 103 moves on the outer shell 101, the three pulleys 109 slide on the slide rail 114. The three pulleys 109 are engaged in the slide rail 114, and the three pulleys 109 play a limiting and guiding role for the protective cover 103, ensuring that the protective cover 103 will not be misaligned during movement. At the same time, the contact area between the three pulleys 109 and the slide rail 114 is small, so the resistance encountered by the protective cover 103 when moving is small, making the protective cover 103 move easily.

[0024] Furthermore, the limiting rod 111 is slidably connected to one end of the fixing frame 110, and one end of the limiting rod 111 extends into the slot 106. The telescopic kit is disposed between the limiting rod 111 and the fixing frame 110.

[0025] Furthermore, the movable block 112 is fixedly connected to the limiting rod 111, and the two ends of the telescopic spring 113 are fixedly connected to the movable block 112 and the fixed frame 110 respectively, and the limiting rod 111 is located inside the telescopic spring 113.

[0026] In this embodiment, when the projection assembly 102 is working, the protective cover 103 is located on one side of the projection assembly 102, and the limiting rod 111 away from the projection assembly 102 is inserted into the slot 106 to fix the protective cover 103, ensuring that the protective cover 103 will not interfere with the operation of the projection assembly 102. When the projection assembly 102 is in use, the two limiting rods 111 are pulled outward, and the two limiting rods 111 move outward respectively, with one of the limiting rods 111 leaving the slot 106, sliding the protective cover 103 onto the projection assembly 102. The moving plate 105 is in the fixed frame. Slide the protective cover 103 within 110 to ensure it does not tilt or misalign until it is in contact with the baffle 104. Then release the limiting rod 111 above the projection assembly 102. The telescopic spring 113 retracts and resets, and drives the limiting rod 111 into the slot 106, fixing the moving plate 105 and the protective cover 103 in place. This ensures the protective cover 103 will not slide. The protective cover 103 and the baffle 104 enclose the projection assembly 102, protecting it from external damage and improving the practicality of the device.

[0027] When the projection assembly 102 is in operation, the protective cover 103 is located on one side of the projection assembly 102. The limiting rod 111, away from the projection assembly 102, is inserted into the slot 106 to fix the protective cover 103, ensuring that the protective cover 103 does not interfere with the operation of the projection assembly 102. After the projection assembly 102 is used, the two limiting rods 111 are pulled outward, and the two limiting rods 111 move outward respectively. One of the limiting rods 111 leaves the slot 106, and the protective cover 103 slides onto the projection assembly 102. The moving plate 105 is fixed in place. The protective cover 103 slides within the frame 110 to ensure it does not tilt or misalign until it is in contact with the baffle 104. Then, the limiting rod 111 above the projection assembly 102 is released, the telescopic spring 113 retracts and resets, and drives the limiting rod 111 into the slot 106, fixing the moving plate 105 and the protective cover 103 to ensure that the protective cover 103 does not slide. The protective cover 103 and the baffle 104 enclose the projection assembly 102, protecting it from external damage and thus improving the practicality of the device.
