Description

Technical Field

[0001] This utility model belongs to the field of calligraphy and painting copying technology, specifically a flip-up calligraphy and painting projection copying device. Background Technology

[0002] Copying calligraphy and painting is the process of imitating calligraphy and painting works according to the original. "Lin" means to write or draw according to the original; "mo" means to write or draw by placing thin paper over the original. When copying calligraphy and painting, traditional copying methods such as tracing require special paper materials that are transparent and do not absorb ink. Moreover, the templates are easily damaged, resulting in a large amount of waste and being environmentally unfriendly. Therefore, beginners will use a calligraphy and painting copying projection device to project the information of the work to be copied onto the table through a projector and a reflector. This not only makes it convenient for people to copy and trace, but also allows them to experience the actual use of ink on Xuan paper.

[0003] The projection range of existing calligraphy and painting projection devices is mostly non-adjustable or can only be adjusted within a certain angle. Their functions are limited, and it is difficult to adjust the size of the projected image according to the size of the calligraphy and painting. This greatly restricts the product's usage environment and fails to meet the growing needs of users.

[0004] In view of this, a flip-up calligraphy and painting projection copying device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a flip-out painting and calligraphy projection copying device in order to solve the problems mentioned above.

[0006] The technical solution adopted by this utility model is as follows: A flip-up calligraphy and painting projection copying device includes a projector, a computer, and a flipping mechanism, a lifting mechanism, and a base connected sequentially from top to bottom. The flipping mechanism includes a flipping bracket, a damping rotating shaft, and a mounting plate. The mounting plate is located in the middle of the damping rotating shaft and is attached to the bottom of the projector by screws. The flipping bracket has a U-shaped structure, and both ends of the damping rotating shaft are mounted on the flipping bracket. The projector can rotate synchronously with the damping rotating shaft to adjust the angle of the projector's projection light path.

[0007] In a preferred embodiment, the lifting mechanism includes an outer column and an inner column. The outer column has a guide cavity with an opening at the upper end, and the inner column is fitted into the guide cavity with a clearance and can slide up and down along the guide cavity.

[0008] In a preferred embodiment, the top of the inner column is flat, the bottom of the flip bracket is detachably mounted on the top of the inner column, and the projector can move up and down synchronously with the damping shaft to adjust the height of the projector's projection light path.

[0009] In a preferred embodiment, the inner column is a hollow structure, and an installation through hole is provided on the outer side wall of the inner column. A locking nut is welded to the inner surface of the installation through hole. An elongated hole opposite to the installation through hole is provided on the outer wall of the outer column. The lifting mechanism also includes a threaded handle. The threaded part of the threaded handle passes through the elongated hole and the installation through hole and is threadedly connected to the locking nut.

[0010] In a preferred embodiment, the computer is housed within the base and is connected to the projector via wired and / or wireless means. The base is also provided with buttons for controlling the computer to be turned on and / or off.

[0011] In a preferred embodiment, the base includes an outer shell and a base plate that interlock with each other, the outer shell and the base plate being connected by screws, and the bottom of the outer column being attached to the outer shell by screws.

[0012] In a preferred embodiment, the housing is provided with heat dissipation holes and external holes for the computer signal antenna to extend out, and the side wall of the housing is also provided with a cable guide for the computer power cord to pass through.

[0013] In a preferred embodiment, anti-slip pads are provided at the four corners of the bottom of the base plate, and a threaded rod is provided at the center of the top of the anti-slip pad.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. In this utility model, a flip mechanism is designed under the projector. Through the cooperation of the damping shaft and the flip bracket, the up and down flip angle of the projector can be adjusted. At the same time, due to the damping efficiency of the damping shaft itself, it can be quickly and easily switched between horizontal desktop and vertical wall projection and tracing use environments, making it more applicable to a wider range of scenarios and having advantages that current products do not have.

[0016] 2. In this utility model, the vertical position of the projector can be adjusted by adjusting the vertical position of the inner column. The size of the projected image on the horizontal table can be controlled by adjusting the height of the projector. Of course, when not in use, the inner column can be retracted into the outer column, which can reduce the overall size and facilitate repositioning and moving during use. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] Reference Figure 1-5 A flip-up projection tracing device for calligraphy and painting includes a projector 1, a computer 9, and a flipping mechanism, a lifting mechanism, and a base connected sequentially from top to bottom. The flipping mechanism includes a flipping bracket 2, a damping shaft 13, and a mounting plate 12. The mounting plate 12 is located in the middle of the damping shaft 13 and is attached to the bottom of the projector 1 by screws. The flipping bracket 2 has a U-shaped structure, and the two ends of the damping shaft 13 are mounted on the flipping bracket 2. The projector 1 can rotate synchronously with the damping shaft 13 to adjust the angle of the projection light path of the projector 1. Through the cooperation of the damping shaft 13 and the flipping bracket 2, the up and down flipping angle of the projector 1 can be adjusted. It can be quickly and easily switched between horizontal desktop and vertical wall projection tracing environments, making it more applicable to a wider range of scenarios. For example, when projected onto a vertical surface, it can be used in teaching scenarios, and when projected onto a horizontal desktop, it can be convenient for personal tracing.

[0025] Among them, the projector 1 is preferably a high-definition resolution projector, which makes the projection clearer. The damping shaft 13 is a rotating shaft with a damping effect (including such as a shaft and several damping pads). The damping shaft 13 with a damping effect enables the projector 1 to stop at any angle on the horizontal, vertical or inclined plane, making it more convenient to use.

[0026] In this embodiment, the lifting mechanism includes an outer column 5 and an inner column 4. The outer column 5 has a guide cavity 14 with an opening at the top. The inner column 4 is fitted into the guide cavity 14 with a clearance and can slide up and down along the guide cavity 14. The top of the inner column 4 is flat. The bottom of the flip bracket 2 is detachably installed on the top of the inner column 4 (preferably connected by screws). The projector 1 can move up and down synchronously with the damping shaft 13 to adjust the height of the projection light path of the projector 1. When adjusting the up and down position of the inner column 4, the up and down position of the projector 1 can be adjusted accordingly. The size of the projected image on the horizontal table can be controlled by adjusting the height of the projector 1. The size of the projected image on the vertical surface can also be controlled by adjusting the distance between the projector 1 and the vertical wall. Of course, when not in use, the inner column 4 can be retracted into the outer column 5 to reduce the overall size and facilitate repositioning and moving during use.

[0027] In this embodiment, the inner column 4 is a hollow structure. An installation through hole is provided on the outer wall of the inner column 4. A locking nut 15 is welded on the inner surface of the installation through hole. An elongated hole opposite to the installation through hole is provided on the outer wall of the outer column 5. The lifting mechanism also includes a threaded handle 3. The threaded part of the threaded handle 3 passes through the elongated hole and the installation through hole and is threadedly connected to the locking nut 15. After adjusting the height of the inner column 4, the threaded handle 3 is screwed inward until it is tightly pressed against the outer wall of the outer column 5, thereby locking the height of the inner column 4. When adjusting the height, the threaded handle 3 is simply screwed outward to make the adjustment. The diameter of the handle part of the threaded handle 3 is larger than the width of the elongated hole.

[0028] In this embodiment, the computer 9 is housed in the base (which can be attached to the base with screws) and communicates with the projector 1 via wired and / or wireless means. The base is also provided with a button 10 to control the computer 9 to turn on and / or off. The button 10 is preferably a red wave button. The computer can transmit professional calligraphy and painting copying content to the projector 1 and project it through the projector 1, which can quickly copy the content without any lag.

[0029] In this embodiment, the base includes a shell 7 and a base plate 8 that are interlocked. The shell 7 and the base plate 8 are connected by screws. The bottom of the outer column 5 is attached to the shell 7 by screws. The shell 7 has heat dissipation holes and an external hole for the computer 9's signal antenna to extend. The base formed by the shell 7 and the base plate 8 can protect the internal computer 9. At the same time, the heat dissipation holes and external holes can meet the heat dissipation requirements of the computer 9 and also expose the computer 9's signal antenna to the outside of the base, so as to avoid signal interference caused by the base covering the computer 9.

[0030] In this embodiment, a wire guide 6 is also provided on the side wall of the outer casing 7 to allow the power cord of the computer 9 to pass through. The power cord of the computer 9 can pass through the wire guide 6 to access the external power source. The wire guide 6 can protect the power cord of the computer 9 and prevent the power cord from being scratched.

[0031] Reference Figure 2 and Figure 3 As shown, anti-slip pads 11 are provided at the four corners of the bottom of the base plate 8. A threaded rod is provided at the center of the top of the anti-slip pad 11. A threaded hole adapted to the threaded rod is opened on the bottom wall of the base plate 8. The anti-slip pads 11 serve as the support part of the projection tracing device and can play an anti-slip role. The bottom of the anti-slip pads 11 is provided with anti-slip materials such as silicone anti-slip pads. At the same time, the screwing in of the threaded rod can be adjusted according to the horizontal difference of the placement surface, thereby adjusting the height and horizontality of the projection tracing device.

[0032] It should be mentioned that the above-mentioned copying device is assembled from multiple individual parts, and if a part is damaged, it can be replaced individually, which helps to save on replacement costs.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
