Description

Technical Field

[0001] The utility model belongs to the technical field of projectors, and in particular relates to an adjustable quick-detachable projection device. Background Art

[0002] A projector is a device that can magnify images or videos and project them onto a screen or wall. It consists of multiple components, including light source, optical system, display screen, control circuit and fixed components, etc. It is widely used in education, business, entertainment and other fields.

[0003] Currently, projectors are fixed with bolts during installation. During long-term use, the bolts are very likely to become thread-stripped, making it extremely difficult to subsequently disassemble the projector. In addition, the angle of the projector cannot be adjusted during use, limiting the flexibility of the projector during use. Therefore, we propose an adjustable quick-release projection device. Utility Model Content

[0004] The purpose of the utility model is to provide an adjustable quick-detachable projection device, which can generate deformation characteristics through a spring, and is used in conjunction with a movable plate, a limit rod, a fixed plate and a pull handle. The positioning rod at the bottom of the projector can be quickly clamped to achieve the purpose of quick installation, and vice versa, it can be quickly removed. At the same time, during the use of the projector, the rotating rod is driven by a motor to rotate, and is used in conjunction with a connecting plate and a clamping box, which will change the angle of use of the projector to achieve the purpose of adjustment, greatly improving the flexibility of the device to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable quick-detachable projection device, comprising a wall-mounted plate, a snap-on box and a projector, wherein a concave frame is fixedly connected to the front surface of the wall-mounted plate, a motor is fixedly installed on one side of the front surface of the concave frame, a rotating rod is fixedly connected to the output end of the motor, a connecting plate is fixedly connected to the surface of the rotating rod, a positioning rod is fixedly connected to the bottom of the projector, and a snap-on ring is fixedly connected to the surface of the positioning rod;

[0006] The front end and the rear end of one side of the card connection box are fixedly connected with a vertical plate, one end of the connecting plate is fixedly connected to the vertical plate by a fastening bolt, a concave block is fixedly connected to the left side of the bottom of the inner cavity of the card connection box, a fixed plate is fixedly connected to the right side of the card connection box, a pull handle is fixedly connected to the right side of the fixed plate, a limiting rod is fixedly connected to the left side of the fixed plate and located in the inner cavity of the card connection box, a movable plate is fixedly connected to the top of the limiting rod, a spring is fixedly connected to the top and bottom of one side of the movable plate, one end of the spring is fixedly connected to the top of the right side of the inner cavity of the card connection box, and a plug hole is opened on the left side of the top of the card connection box.

[0007] By adopting the above scheme, first, the positioning rod at the bottom of the projector is inserted into the inner cavity of the card box through the plug hole. During the process of the positioning rod descending, the bottom of the positioning rod will contact one side of the limit rod. During the contact process, the limit rod will be driven to move to the right side by the downward pressure. During the movement of the limit rod, the fixed plate and the movable plate will be driven to move to one side at the same time. At the same time, the spring is squeezed by the movable plate to deform the spring. When the bottom of the positioning rod is tightly fitted with the bottom of the inner cavity of the concave block, the limit rod will be reset by utilizing the characteristics of the spring, so that one end of the limit rod and the top of the clamping ring on the surface of the positioning rod will conflict with each other to achieve the purpose of clamping. Then, during the use of the projector, when the angle of the projector needs to be adjusted, the rotating rod is driven to rotate by the motor, the connecting plate is driven to rotate by the rotating rod, and the card box is driven to rotate by the connecting plate. During the rotation of the card box, the angle of use of the projector will be changed, so as to achieve the purpose of adjustment, thereby greatly improving the flexibility of the device.

[0008] As a preferred embodiment of an adjustable quick-detachable projection device, the bottom of the rotating rod is fixedly connected to a guide wheel, and the bottom of the guide wheel is movably connected to a support rod.

[0009] With the above solution, by setting the support rod, when the limit rod drives the guide wheel to move to one side, the support rod will move, thereby assisting the limit rod to move, thereby improving the smoothness of the device.

[0010] As a preferred embodiment of an adjustable quick-detachable projection device, a power supply box is fixedly connected to the bottom of the concave frame, and a battery is provided in the inner cavity of the power supply box.

[0011] By adopting the above scheme, the motor can be powered separately by the battery to maintain the normal operation of the motor and avoid the motor failing to work properly due to power failure.

[0012] As a preferred embodiment of an adjustable quick-detachable projection device, mounting bolts are threadedly connected around the inner cavity of the wall hanging plate, and the number of the mounting bolts is four.

[0013] By adopting the above solution, utilizing the compatibility of the mounting bolts with the external threaded holes and using them in conjunction with external tools, the wall-mounted plate can be quickly fixed to a designated position, thereby achieving the purpose of rapid installation.

[0014] As a preferred embodiment of an adjustable quick-detachable projection device, a bearing is sleeved on one side of the rotating rod, and one side of the bearing is fixedly connected to one side of the inner side of the concave frame.

[0015] By adopting the above scheme, the bearing is set to avoid the rotating rod from being suspended, limit and support it, and at the same time utilize the characteristics of the bearing to reduce the wear of the rotating rod during operation, thereby greatly improving the service life of the rotating rod.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] When the bottom of the positioning rod is tightly fitted with the bottom of the inner cavity of the concave block, the limit rod is reset by utilizing the characteristics of the spring, so that one end of the limit rod and the top of the clamping ring on the surface of the positioning rod contact each other to achieve the purpose of clamping. Then, when the angle of the projector needs to be adjusted during use, the motor drives the rotating rod to rotate, the rotating rod drives the connecting plate to rotate, and the connecting plate drives the clamping box to rotate. During the rotation of the clamping box, the angle of use of the projector will be changed, so as to achieve the purpose of adjustment, thereby greatly improving the flexibility of the device.

[0018] 2. The utility model prevents the rotating rod from being suspended in the air by setting the bearing, limits and supports it, and at the same time utilizes the characteristics of the bearing to reduce the wear of the rotating rod during operation, thereby greatly improving the service life of the rotating rod.

Figure 2As shown, the bottom of the rotating rod 4 is fixedly connected with a guide wheel 19, and the bottom of the guide wheel 19 is movably connected with a support rod 18. Through the setting of the support rod 18, when the limit rod 12 drives the guide wheel 19 to move to one side, it will cause the support rod 18 to move, thereby assisting the limit rod 12 to move, thereby improving the smoothness of the device. The surface of the rotating rod 4 is fixedly connected with a connecting plate 5, and the bottom of the projector 10 is fixedly connected with a positioning rod 17, and the surface of the positioning rod 17 is fixedly connected with a clamping ring. Figure 3 As shown, a bearing is sleeved on one side of the rotating rod 4, and one side of the bearing is fixedly connected to one side of the inner side of the concave frame 2. The arrangement of the bearing can prevent the rotating rod 4 from being suspended in the air, limit and support it, and at the same time, the characteristics of the bearing are utilized to reduce the wear of the rotating rod 4 during operation, thereby greatly improving the service life of the rotating rod 4.

[0025] Insert the positioning rod 17 at the bottom of the projector 10 into the inner cavity of the card box 6 through the plug hole 9. During the descent of the positioning rod 17, the bottom of the positioning rod 17 will contact one side of the limiting rod 12. During the contact process, the limiting rod 12 will be driven to move to the right by the downward pressure. During the movement of the limiting rod 12, the fixed plate 15 and the movable plate 13 will be driven to move to one side at the same time. At the same time, the spring 14 is squeezed by the movable plate 13, so that the spring 14 is deformed. When the bottom of the positioning rod 17 is tightly fitted with the bottom of the inner cavity of the concave block 11, the spring 14 is deformed by using the elastic force. The characteristics of the spring 14 will reset the limit rod 12, so that one end of the limit rod 12 contacts the top of the clamping ring on the surface of the positioning rod 17, thereby achieving the purpose of clamping. Then, during the use of the projector 10, when the angle of the projector 10 needs to be adjusted, the motor 3 drives the rotating rod 4 to rotate, the rotating rod 4 drives the connecting plate 5 to rotate, and the connecting plate 5 drives the clamping box 6 to rotate. During the rotation of the clamping box 6, the angle of use of the projector 10 will be changed, thereby achieving the purpose of adjustment, thereby greatly improving the flexibility of the device.

[0026] See Figure 3As shown, the bottom of the concave frame 2 is fixedly connected with a power supply box, and the inner cavity of the power supply box is provided with a battery.

[0027] When in use, first place the wall hanging plate 1 at the position where it needs to be installed, and align the threaded holes on the surface of the wall hanging plate 1 with the threaded grooves on the wall. Secondly, use an external tool to rotate the mounting bolts through the threaded holes into the threaded grooves of the wall to fix the wall hanging plate 1. Then the user inserts the positioning rod 17 at the bottom of the projector 10 into the inner cavity of the card box 6 through the plug hole 9. During the descent of the positioning rod 17, the bottom of the positioning rod 17 will contact one side of the limiting rod 12. During the contact process, the limiting rod 12 will be driven to move to the right side by the downward pressure. During the movement of the limiting rod 12, the fixed plate 15 and the movable plate 13 will be driven to move to one side at the same time. At the same time, the spring 14 is squeezed by the movable plate 13, causing the spring 14 to deform. When the bottom of the positioning rod 17 is tightly fitted with the bottom of the inner cavity of the concave block 11, the characteristics of the spring 14 will be used to The limit rod 12 is reset so that one end of the limit rod 12 contacts with the top of the clamping ring on the surface of the positioning rod 17 to achieve the purpose of clamping.
