Description

Technical Field

[0001] This utility model relates to the field of digital cinema projector technology, specifically a support device for a digital cinema projector. Background Technology

[0002] Digital cinema refers to films where digital processing technology partially or entirely replaces traditional optical, chemical, or physical processing techniques in all stages of filmmaking, post-production, and distribution, and digital media replaces film. Compared to traditional film, digital cinema's advantages primarily lie in reduced production costs, innovative production methods, and improved production quality. Digital cinema projectors utilize digital optical switch arrays and digital signal processing. Compared to traditional film, digital cinema projectors offer significant technological advantages in distribution and screening, including no jitter, reduced likelihood of projection accidents (film breakage), lower projection costs, vibrant and rich colors, stable viewing quality, simplified distribution methods, and easy storage. They can also effectively provide value-added services. When using a digital cinema projector, a support device is typically required to ensure its stability during projection and prevent image distortion or misalignment due to vibration or movement. Support devices are used to fix and support digital cinema projectors. They typically include tripods, jacks, wall mounts, etc. Depending on the projection venue, a suitable support method can be selected. These devices can ensure the stability and accuracy of the projector, enabling it to be correctly aligned with the screen and guaranteeing stability and reliability during the projection process.

[0003] When supporting a digital cinema projector using a support device, the projector is typically placed on the device and connected to it using screws and nuts. Alternatively, anti-slip pads or feet are placed at the contact points between the projector's bottom and the support device to increase friction and prevent slippage during movement or adjustment. Connecting the projector and support device by tightening screws and nuts is cumbersome and inconvenient. Furthermore, the use of anti-slip pads or feet can compromise the stability of the projector on the support device, failing to secure it properly and thus compromising its protection. Therefore, the safety of the support device for supporting the projector needs improvement. To address these issues, a support device for digital cinema projectors is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a support device for a digital cinema projector, in order to solve the problem mentioned in the background art that the method of connecting the digital cinema projector and the support device by tightening screws and nuts is cumbersome and troublesome. Furthermore, the use of protective pads or feet makes the digital cinema projector less stable when placed on the support device, thus failing to properly fix the digital cinema projector and consequently not protecting it. Therefore, the safety of the support device for supporting the digital cinema projector needs to be improved.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a support device for a digital cinema projector, comprising a frame, the frame comprising a support rod, a support leg movably connected to the surface of the support rod, a support plate fixedly connected to the top end of the support rod, a connecting rod fixedly connected to the upper surface of the support plate, a placement plate movably connected to the top end of the connecting rod, the placement plate being movably connected to the connecting rod via a rotating shaft, and a digital cinema projector body being disposed on the upper surface of the placement plate;

[0006] The surface of the placement plate is provided with a limiting mechanism, which includes a movable groove. The movable groove is opened on the inner side of the placement plate. A positive and negative screw is movably connected to the inner side of the movable groove. The positive and negative screw is movably connected to the placement plate. A moving block is threadedly connected to the surface of the positive and negative screw. A limiting plate is fixedly connected to the upper surface of the moving block. A connecting plate is fixedly connected to the surface of the limiting plate. A first threaded rod is threadedly connected to the inner side of the connecting plate. A pressure plate is fixedly connected to the bottom end of the first threaded rod. A baffle is fixedly connected to the upper surface of the placement plate.

[0007] Preferably, the limiting mechanism further includes a first rubber pad, which is fixedly connected to the inner surface of the limiting plate. A limiting groove is formed on the inner side of the placement plate, and the limiting plate moves within the limiting groove. A second rubber pad is fixedly connected to the lower surface of the pressure plate.

[0008] Preferably, the movable blocks are arranged in two groups and movably connected to the positive and negative screws, the movable blocks are movable inside the movable groove, and the limiting plates are arranged in two groups and correspondingly connected to the movable blocks.

[0009] Preferably, the connecting plates are connected in two sets to the limiting plates, the first threaded rods are connected in two sets to the connecting plates, the pressure plates are connected in two sets to the first threaded rods, and the baffles are fixedly connected in two sets to the upper surface of the placement plate.

[0010] Preferably, the surface of the support plate is provided with an adjustment mechanism, the adjustment mechanism including a fixed plate, the fixed plate being fixedly connected to the upper surface of the support plate, a second threaded rod being movably connected to the inner side of the fixed plate, a movable plate being threadedly connected to the surface of the second threaded rod, a movable rod being movably connected to the upper surface of the movable plate, and a limit rod being fixedly connected to the inner surface of the fixed plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By rotating the forward and reverse screws, the moving block can drive the limiting plate to move, thereby limiting the two ends of the digital cinema projector body. By rotating the first threaded rod, the pressure plate can press the digital cinema projector body tightly, making it difficult for the digital cinema projector body to move longitudinally. The baffle can block the front and rear of the digital cinema projector body, preventing it from moving forward or backward and making it difficult for it to slide. This allows the digital cinema projector body to be fixed on the placement plate in a convenient way, making the support device safer when supporting the digital cinema projector body and improving the stability of digital cinema projection. At the same time, the setting of the first and second rubber pads can increase the friction between the limiting plate and the pressure plate and the digital cinema projector body, making the limiting plate and the pressure plate more stable in limiting and pressing the digital cinema projector body, thus improving the fixing effect. The setting of the first and second rubber pads can also protect the surface of the digital cinema projector body, preventing the limiting plate and the pressure plate from excessively squeezing the digital cinema projector body.

[0014] 2. By rotating the second threaded rod, the movable plate can be moved, which in turn drives the movable rod to move. Consequently, the placement plate will move under the action of the movable rod, achieving the effect of adjusting the angle of the digital cinema projector body. By adjusting the angle of the digital cinema projector body, the support device can provide more flexible support for the digital cinema projector body. Therefore, during projection, the angle of the digital cinema projector body can be flexibly adjusted according to actual needs, so that the digital cinema projector body can be more accurately aligned with the screen, which helps to ensure that the image can be projected completely onto the screen.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 One embodiment provided by this utility model:

[0022] A support device for a digital cinema projector includes a frame, which includes a support rod 1. A support leg 11 is movably connected to the surface of the support rod 1. A support plate 12 is fixedly connected to the top of the support rod 1. A connecting rod 13 is fixedly connected to the upper surface of the support plate 12. A placement plate 14 is movably connected to the top of the connecting rod 13. The placement plate 14 is movably connected to the connecting rod 13 via a pivot. A digital cinema projector body 15 is mounted on the upper surface of the placement plate 14. The support rod 1 and the support leg 11 can support the support plate 12, and the placement plate 14 can support the digital cinema projector body 15, thereby facilitating the placement of the digital cinema projector body 15 and enabling the projection of digital cinema films through the digital cinema projector body 15.

[0023] A limiting mechanism is provided on the surface of the placement plate 14. The limiting mechanism includes a movable groove 2, which is opened on the inner side of the placement plate 14. A positive and negative screw 21 is movably connected to the inner side of the movable groove 2. The positive and negative screw 21 is movably connected to the placement plate 14. A moving block 22 is threadedly connected to the surface of the positive and negative screw 21. A limiting plate 23 is fixedly connected to the upper surface of the moving block 22. A connecting plate 26 is fixedly connected to the surface of the limiting plate 23. A first threaded rod 27 is threadedly connected to the inner side of the connecting plate 26. A pressure plate 28 is fixedly connected to the bottom end of the first threaded rod 27. A baffle 210 is fixedly connected to the upper surface of the mounting plate 14. By setting the first threaded rod 27, rotating the first threaded rod 27 can cause the pressure plate 28 to move vertically under the action of the first threaded rod 27. In this way, the pressure plate 28 can press down on the top of the digital cinema projector body 15, so that the digital cinema projector body 15 cannot move longitudinally. Therefore, when the device supports the digital cinema projector body 15, it is convenient to fix the digital cinema projector body 15 and can ensure the safety of the digital cinema projector body 15.

[0024] Furthermore, the limiting mechanism also includes a first rubber pad 24, which is fixedly connected to the inner surface of the limiting plate 23. A limiting groove 25 is formed on the inner side of the placement plate 14, and the limiting plate 23 moves within the limiting groove 25. A second rubber pad 29 is fixedly connected to the lower surface of the pressure plate 28. By setting the first rubber pad 24 and the second rubber pad 29, the friction between the limiting plate 23 and the pressure plate 28 and the surface of the digital cinema projector body 15 can be increased, resulting in a better fixing effect on the digital cinema projector body 15. Consequently, the digital cinema projector body 15 is more stable, and the limiting plate 23 and the pressure plate 28 can also prevent the limiting plate 23 and the pressure plate 28 from causing indentations on the surface of the digital cinema projector body 15.

[0025] Furthermore, the movable block 22 is movably connected to the positive and negative screws 21 in two sets. The movable block 22 is movable inside the movable groove 2. The limiting plate 23 is correspondingly connected to the movable block 22 in two sets. By setting the movable block 22, when the positive and negative screws 21 rotate, the movable block 22 can move under the action of the positive and negative screws 21 and drive the limiting plate 23 to move accordingly. Thus, the limiting plate 23 can limit the left and right ends of the digital cinema projector body 15, which can realize the fixation of the digital cinema projector body 15, so that the placement of the digital cinema projector body 15 on the placement plate 14 is more stable.

[0026] Furthermore, the connecting plate 26 is connected to the limiting plate 23 in two sets, the first threaded rod 27 is connected to the connecting plate 26 in two sets, the pressure plate 28 is connected to the first threaded rod 27 in two sets, and the baffle 210 is fixedly connected to the upper surface of the placement plate 14 in two sets. By setting the baffle 210, the front and rear ends of the digital cinema projector body 15 can be limited, so that when the digital cinema projector body 15 is placed, it can be positioned to prevent the digital cinema projector body 15 from moving forward or backward and slipping off the placement plate 14.

[0027] Furthermore, the surface of the support plate 12 is provided with an adjustment mechanism, which includes a fixed plate 3. The fixed plate 3 is fixedly connected to the upper surface of the support plate 12. A second threaded rod 31 is movably connected to the inner side of the fixed plate 3. A movable plate 32 is threadedly connected to the surface of the second threaded rod 31. A movable rod 33 is movably connected to the upper surface of the movable plate 32. A limit rod 34 is fixedly connected to the inner surface of the fixed plate 3. By rotating the second threaded rod 31, the movable plate 32 can be moved and the movable rod 33 can be moved, thereby adjusting the angle of the placement plate 14. This allows for adjustment of the angle of the digital cinema projector body 15, making the support of the device for the digital cinema projector body 15 more flexible and facilitating better projection through the digital cinema projector body 15.

[0028] Furthermore, one end of the movable rod 33 is movably connected to the moving plate 32 via a rotating shaft, and the other end of the movable rod 33 is movably connected to the placement plate 14 via a rotating shaft. The moving plate 32 is movably connected to the limiting rod 34. By setting the limiting rod 34, the moving plate 32 can be limited, which can prevent the moving plate 32 from shifting under the action of the second threaded rod 31, and facilitate the stable movement of the moving plate 32.

[0029] Working principle: In use, the baffle 210 blocks the front and rear ends of the digital cinema projector body 15. By rotating the positive and negative screws 21, the moving block 22 will move inside the movable groove 2 under the action of the positive and negative screws 21. Then, the limiting plate 23 will move inside the limiting groove 25 under the action of the moving block 22, and the first rubber pad 24 will contact the two ends of the digital cinema projector body 15, so that the limiting plate 23 limits the two ends of the digital cinema projector body 15. Then, by rotating the first threaded rod 27, the pressure plate 28 will move down under the action of the first threaded rod 27, and the second rubber pad 29 will contact the upper surface of the digital cinema projector body 15, so that the pressure plate 28 presses the digital cinema projector body 15 tightly, and the digital cinema projector body 15 can be fixed on the placement plate 14.

[0030] By rotating the second threaded rod 31, the moving plate 32 is limited by the limiting rod 34, causing the moving plate 32 to move horizontally under the action of the second threaded rod 31 and move on the surface of the limiting rod 34. Then, the moving rod 33 moves through the rotating shaft under the action of the moving plate 32, so that the placement plate 14 moves accordingly under the action of the moving rod 33, which can achieve the effect of adjusting the angle of the digital cinema projector body 15.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
