Description

Technical Field

[0001] This utility model relates to the field of projector technology, and in particular to an adjustable training projector. Background Technology

[0002] Adjustable training projectors, as core equipment in the education and training field, primarily display teaching content such as images and videos on a screen through optical projection principles. They are widely used in classroom teaching, corporate training, academic lectures, and other scenarios. In practical applications, adjustable training projectors typically require the following structure: 1. The projector itself, as the core component, integrates the light source, imaging system, and projection lens, and is responsible for generating and projecting images; 2. The chassis is used to support the projector body and provide stable support; 3. The angle adjustment mechanism realizes the pitch and horizontal rotation adjustment of the projector through mechanical transmission.

[0003] Currently, training projectors on the market employ various design solutions to achieve diverse functions. Some products use electric motors for automatic angle adjustment, while others use large-area heat dissipation holes combined with silent fans to enhance heat dissipation. Some projectors also add a dust-proof coating to the surface of the casing to reduce dust accumulation.

[0004] However, the above-mentioned implementation methods still have the following problems: In terms of angle adjustment, traditional mechanical structures lack sufficient adjustment precision, are prone to angle deviation, and are cumbersome to operate, making it difficult to quickly adapt to the projection needs of different training scenarios. In terms of equipment maintenance, most projectors' heat dissipation systems rely solely on protective nets for passive dust prevention, failing to actively remove dust accumulation in the heat dissipation slots. As usage time increases, dust accumulation leads to decreased heat dissipation efficiency, thereby affecting equipment performance and lifespan, and even causing malfunctions. This adjustable training projector addresses this issue by proposing an optimized solution. A precision angle adjustment mechanism combining a serrated limit slot and a return spring achieves high-precision and rapid angle adjustment. Simultaneously, a self-cleaning protective net structure is designed to clean the heat dissipation slots simultaneously when the protective net is removed, effectively solving the problem of dust accumulation affecting heat dissipation and significantly improving equipment stability and durability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable training projector that solves the problems of insufficient adjustment precision, easy angle deviation, cumbersome operation, and difficulty in quickly adapting to the projection needs of different training scenarios in traditional mechanical structures. In terms of equipment maintenance, most projectors' heat dissipation systems rely solely on protective meshes for passive dust prevention and cannot actively remove dust accumulation in the heat dissipation slots. As usage time increases, dust accumulation leads to a decrease in heat dissipation efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An adjustable training projector includes a projector body, a fixed plate fixedly connected to the lower surface of the projector body, a base rotatably connected to the lower end of the fixed plate, protective nets on both the left and right sides of the projector body, two heat dissipation plates fixedly connected inside the projector body, fixed plates on the opposite sides of the two protective nets, a set of cleaning cotton fixedly connected to the opposite sides of the two fixed plates, a connecting block fixedly connected to the annular side of the base, a limit block movably engaging within the connecting block, a return spring fixedly connected to the right surface of the limit block, and a set of slots opened on the annular side of the fixed plate, with the limit block movably engaging with the set of slots.

[0007] Preferably, the projector body has guide grooves on both the left and right sides, the two protective nets are movably connected to the two guide grooves respectively, the limiting block has push blocks fixedly connected to both the front and rear sides, the connecting block has a rectangular groove on its left surface, and the limiting block is movably engaged with the rectangular groove.

[0008] Preferably, the reset spring is fixedly connected to the rectangular groove, two screws are provided on the surface of each of the two protective nets, and the two protective nets are fixedly connected to the projector body by two pairs of screws respectively, and the two sets of cleaning cotton are movably snapped into the two heat sinks respectively.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. The limiting block and the slot adopt a sawtooth interlocking design. This structure can not only achieve precise positioning at multiple angles, but also effectively prevent the angle deviation caused by vibration or external force during the use of the equipment. After the angle adjustment is completed, the push block is released, and the reset spring immediately releases the stored elastic potential energy, driving the limiting block to quickly reset and re-embed into the slot of the fixed plate to form a reliable mechanical lock. The whole system not only meets the needs of rapid adjustment of projection direction in training scenarios, but also ensures the stability of the equipment during long-term use, greatly reducing the difficulty of equipment adjustment and making it suitable for rapid deployment in various training scenarios.

[0010] 2. As the protective net slides along the guide groove, the cleaning cotton simultaneously wipes the inner wall of the heat dissipation slot, effectively removing attached dust, fibers, and other debris. The cleaning cotton is set on a fixed plate, which is fixed to the protective net with screws. The modular design allows for direct replacement of the cleaning cotton when the soiling is severe, eliminating the need to replace the entire protective net. By combining the disassembly process of the protective net with the cleaning process of the heat dissipation slot, the efficient operation of disassembly and cleaning is achieved. The protective net can block large particles of debris from entering the machine body, while the cleaning cotton can clean the residual micro-dust in the heat dissipation slot, forming a dual protection of coarse filtration and fine cleaning.

[0014] This application provides an adjustable training projector that effectively solves the problems of insufficient adjustment precision, easy angle deviation, cumbersome operation, and difficulty in quickly adapting to the projection needs of different training scenarios in traditional mechanical structures. In terms of equipment maintenance, most projectors' heat dissipation systems rely solely on protective nets for passive dust prevention and cannot actively remove dust accumulation in the heat dissipation slots. As usage time increases, dust accumulation leads to a decrease in heat dissipation efficiency. The precision angle adjustment mechanism, which combines a serrated limit slot with a reset spring, achieves high-precision and rapid angle adjustment. At the same time, a self-cleaning protective net structure is designed to clean the heat dissipation slots simultaneously when the protective net is removed, effectively solving the problem of dust accumulation affecting heat dissipation and significantly improving the stability and durability of the equipment. Example

[0015] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problems of insufficient adjustment precision of traditional mechanical structures, easy angle deviation, cumbersome operation, and difficulty in quickly adapting to the projection needs of different training scenarios. In terms of equipment maintenance, most projectors' heat dissipation systems rely solely on protective meshes for passive dust prevention and cannot actively remove dust accumulation in the heat dissipation slots. As usage time increases, dust accumulation leads to a decrease in heat dissipation efficiency. The overall approach is as follows: To address the problems existing in the prior art, this utility model provides an adjustable training projector, including a projector body 1. A fixed plate 4 is fixedly connected to the lower surface of the projector body 1, and a base 3 is rotatably connected to the lower end of the fixed plate 4. Protective nets 2 are provided on both the left and right sides of the projector body 1. Two heat dissipation plates 7 are fixedly connected inside the projector body 1. Fixed plates 14 are provided on the opposite sides of the two protective nets 2. A set of cleaning cotton 13 is fixedly connected to the opposite sides of the two fixed plates 14. A connecting block 5 is fixedly connected to the annular side of the base 3. A limit block 8 is movably engaged inside the connecting block 5. A return spring 9 is fixedly connected to the right surface of the limit block 8. A set of slots 12 are opened on the annular side of the fixed plate 4. The limit block 8 is movably engaged with the set of slots 12. When it is necessary to adjust the angle of the projector body 1, the operator manually pulls two symmetrically distributed push blocks 11, which drive the limit block 8 rigidly connected to them to move along a preset slide rail. During this process, the return spring 9 is fixedly connected to the limit block 8. The spring 9 is compressed and undergoes elastic deformation, storing potential energy. As the limiting block 8 moves, its engagement with the slot 12 on the fixed plate 4 is released. The fixed plate 4, as a key component for angle adjustment, forms a rotating joint with the chassis 3, ensuring that the projector body 1 can rotate smoothly and stably. The limiting block 8 and the slot 12 adopt a serrated interlocking design. This structure can not only achieve precise positioning at multiple angles, but also effectively prevent angle deviation caused by vibration or external force during use. After the angle adjustment is completed, the push block 11 is released, and the reset spring 9 immediately releases the stored elastic potential energy, driving the limiting block 8 to quickly reset and re-embed into the slot 12 of the fixed plate 4, forming a reliable mechanical lock. The whole system not only meets the need for rapid adjustment of the projection direction in training scenarios, but also ensures the stability of the equipment during long-term use, greatly reducing the difficulty of equipment adjustment, and is suitable for rapid deployment in various training scenarios.

[0016] The projector body 1 has guide grooves 6 on both the left and right sides. Two protective nets 2 are movably connected to the two guide grooves 6 respectively. Push blocks 11 are fixedly connected to the front and rear sides of the limiting block 8. A rectangular groove 10 is opened on the left surface of the connecting block 5. The limiting block 8 is movably engaged with the rectangular groove 10. The return spring 9 is fixedly connected to the rectangular groove 10. Two screws are provided on the surface of each of the two protective nets 2. The two protective nets 2 are fixedly connected to the projector body 1 by two pairs of screws respectively. Two sets of cleaning cotton 13 are movably engaged with two heat dissipation plates 7 respectively. The protective nets 2 adopt a modular design and are detachably connected to the projector body 1 by screws. When disassembling, the operator only needs to loosen the fixing screws to release the mechanical limit, and then push the protective net 2 forward along the guide groove 6 to complete the quick disassembly. The protective net 2 contains an integrated cleaning cotton 13, which is precisely fitted into the heat dissipation groove on the surface of the heat dissipation plate 7. When the protective net 2 slides along the guide groove 6, the cleaning cotton 13 simultaneously wipes the inner wall of the heat dissipation groove, effectively removing attached dust, fibers and other debris. The cleaning cotton 13 is set on the fixing plate 14, which is fixed to the protective net 2 with screws. The modular design allows the cleaning cotton 13 to be replaced directly when the net is heavily soiled, without the need to replace the entire protective net 2. By combining the disassembly process of the protective net 2 with the cleaning process of the heat dissipation groove, the efficient operation of disassembly and cleaning is achieved. The protective net 2 can block large particles of debris from entering the machine body, while the cleaning cotton 13 can clean the residual micro dust in the heat dissipation groove, forming a dual protection of coarse filtration and fine cleaning.

[0017] Among them, the projector body 1: integrates the light source, imaging system and projection lens, generates and projects images, and is the core component of the projector, providing image display for training; Protective net 2: blocks large particles of debris from entering the machine body. When detached, it can drive the cleaning cotton 13 to clean the heat dissipation groove, achieving coarse filtration and fine cleaning during maintenance. Chassis 3: Supports the projector body 1, providing stable support and ensuring the stability of the projector during placement and adjustment; Fixed plate 4: Rotatably connected to the base plate 3, driving the projector body 1 to rotate, and the slot 12 on it cooperates with the limiting block 8 to realize angle adjustment and positioning; Connecting block 5: It is a movable latching block 8, providing an installation position for the limiting block 8 so that it can move within it and assist in realizing the angle adjustment function; Guide groove 6: guides the movement of the protective net 2, allowing the protective net 2 to slide and be disassembled along it, ensuring that the cleaning cotton 13 cleans the heat dissipation groove simultaneously; Heat sink 7: Heat dissipation grooves are provided on it to work with the heat dissipation system to ensure that the heat of the projector body 1 is dissipated during operation and to maintain the performance of the equipment; Limiting block 8: engages with slot 12 to achieve precise positioning of the projector body at angle 1, preventing displacement due to vibration or external force and ensuring projection stability; Return spring 9: Stores potential energy after compression, and drives limit block 8 to reset when released. It works with limit block 8 to achieve automatic locking after angle adjustment. Rectangular groove 10: provides a movable limit block 8, provides a fixed position for the reset spring 9, and assists the limit block 8 and the reset spring 9 in completing the angle adjustment operation; Push block 11: for the operator to pull, which moves the limit block 8 to release the limit and facilitate the angle adjustment of the projector body 1; Slot 12: Engages with the serrated limit block 8 to achieve precise positioning at multiple angles, prevent equipment angle deviation, and ensure stable projection direction; Cleaning cotton 13: Wipe the heat dissipation groove when the protective net 2 is removed to remove dust, fibers and other debris, actively clean the heat dissipation channel and maintain heat dissipation efficiency; Fixing plate 14: Fixes the cleaning cotton 13 on the protective net 2, so that the cleaning cotton 13 can move with the protective net 2 to clean the heat dissipation groove, and is easy to disassemble and replace.

[0018] Working principle: When the angle of the projector body 1 needs to be adjusted, the operator manually pulls the two symmetrically distributed push blocks 11, causing the rigidly connected limit block 8 to move along the preset slide rail. During this process, the return spring 9 is compressed and undergoes elastic deformation, storing potential energy. As the limit block 8 moves, its engagement with the slot 12 on the fixed plate 4 is released. The fixed plate 4, as a key component for angle adjustment, forms a rotating joint with the chassis 3, ensuring that the projector body 1 can rotate smoothly and stably. The limit block 8 and the slot 12 adopt a sawtooth interlocking design. This structure not only enables precise positioning at multiple angles but also effectively prevents angle deviation caused by vibration or external force during use. After the angle adjustment is completed, the push blocks 11 are released, and the return spring 9 immediately releases the stored elastic potential energy, driving the limit block 8 to quickly reset and re-embed into the slot 12 of the fixed plate 4, forming a reliable mechanical lock. Overall, this not only meets the need for rapid adjustment of the projection direction in training scenarios but also ensures the stability of the equipment during long-term use, significantly reducing the risk of accidents. The equipment is easy to adjust and suitable for rapid deployment in various training scenarios. The protective net 2 adopts a modular design and is detachably connected to the projector body 1 with screws. During disassembly, the operator only needs to loosen the fixing screws to release the mechanical limit, and then push the protective net 2 forward along the guide groove 6 to complete the quick disassembly. The protective net 2 is equipped with an integrated cleaning cotton 13, which is precisely engaged in the heat dissipation groove on the surface of the heat dissipation plate 7. When the protective net 2 slides along the guide groove 6, the cleaning cotton 13 simultaneously wipes the inner wall of the heat dissipation groove, effectively removing attached dust, fibers and other debris. The cleaning cotton 13 is set on the fixing plate 14, which is fixed to the protective net 2 with screws. The modular design allows the cleaning cotton 13 to be replaced directly when the dirt is severe, without having to replace the entire protective net 2. By combining the disassembly process of the protective net 2 with the heat dissipation groove cleaning process, the efficient operation of disassembly and cleaning is achieved. The protective net 2 can block large particles of debris from entering the machine body, while the cleaning cotton 13 can clean the residual micro dust in the heat dissipation groove, forming a dual protection of coarse filtration and fine cleaning.
