Technical Field
[0001] This utility model relates to a drawer-type keyboard holder for a 3D printing device. Background Technology
[0002] SLA (Stereolithography) 3D printing equipment is an additive manufacturing device that uses the principle of photopolymerization to solidify liquid photosensitive resin layer by layer to build three-dimensional objects. Its working principle involves model design and slicing: First, a model of the object is designed using professional 3D modeling software. Then, slicing software breaks the model down into layers of thin slab data and generates printing instructions. Next is the photopolymerization process: The printer's ultraviolet light source (usually a laser) scans the liquid photosensitive resin layer by layer according to the slicing data, causing the resin to solidify in the laser-irradiated area. After each layer is solidified, the platform adjusts its height slightly to continue printing the next layer. Finally, printing and post-processing are completed: After printing, the model undergoes post-processing steps such as removing support structures, cleaning the surface, and re-curing to ensure quality and durability.
[0003] There are two main types of keyboards used in SLA stereolithography 3D printing equipment on the market. One type integrates a touchscreen to replace the traditional keyboard, but its precision in operation is not high enough. The other type uses a cantilever to mount the monitor and keyboard tray on the outer casing. This method significantly increases the size of the equipment, making it more space-consuming and inconvenient to transport.
[0004] Therefore, a drawer-type keyboard holder for 3D printing equipment is proposed to address the above problems. Utility Model Content
[0005] The purpose of this utility model is to overcome the existing defects and provide a drawer-type keyboard bracket for 3D printing equipment, which reduces the size of the equipment, reduces the floor space, and makes the equipment structure more compact.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a drawer-type keyboard support for a 3D printing device, comprising a keyboard drawer, a drawer sliding assembly, a drawer limiting assembly, and a mouse cover;
[0007] The keyboard drawer is slidably connected to the inside of the device frame via the drawer sliding assembly; the drawer limiting assembly is disposed inside the device frame to restrict the opening and closing of the keyboard drawer; the mouse cover is rotatably connected to one side of the upper surface of the keyboard drawer.
[0008] Preferably, the drawer sliding assembly includes two two-section drawer slides, which are respectively disposed on both sides inside the device frame, and one two-section drawer slide is connected to each side of the keyboard drawer.
[0009] Preferably, the drawer limiting assembly includes a cabinet door rebounder, which is connected to the inside of the equipment frame via a rebounder mounting plate.
[0010] Preferably, a slide rail mounting plate is connected to each side of the equipment frame, and the two drawer slide rails are connected to the corresponding slide rail mounting plates.
[0011] Preferably, the two sides of the mouse cover are rotatably connected to the inside of the keyboard drawer via two pivots; a V-shaped rotating spring is fitted on the pivot.
[0012] Preferably, the mouse cover is L-shaped.
[0013] Preferably, the slide rail mounting plate is connected to the device frame and the two-section drawer slide rail by a plurality of first screws.
[0014] Preferably, the rebounder mounting plate is connected to the equipment frame and the cabinet door rebounder by a plurality of second screws.
[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: The drawer-type keyboard bracket of this 3D printing equipment, through the setting of drawer sliding components and drawer limiting components, allows the keyboard to be hidden inside the equipment. It can be easily pushed out when in use and pushed back in like a drawer when not in use. This reduces the equipment's footprint, making it smaller for transport, while also achieving a convenient and quick operation method. Due to the drawer-type keyboard structure, the equipment's size and footprint are reduced, making the equipment more compact and aesthetically pleasing, significantly improving space utilization. The storage and use of the keyboard and mouse are also more convenient. Attached Figure Description

[0022] 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.
[0023] Please see Figure 1-4 A drawer-type keyboard bracket for a 3D printing device includes a keyboard drawer 1, a drawer sliding assembly, a drawer limiting assembly, and a mouse cover 2. The keyboard drawer 1 is slidably connected to the inside of the device frame 3 via the drawer sliding assembly. The drawer limiting assembly is located inside the device frame 3 to restrict the opening and closing of the keyboard drawer 1. The mouse cover 2 is rotatably connected to one side of the upper surface of the keyboard drawer 1.
[0024] Specifically, the drawer sliding assembly includes two two-section drawer slides 4, which are respectively located on both sides inside the device frame 3. One two-section drawer slide 4 is connected to each side of the keyboard drawer 1. A slide mounting plate 6 is connected to each side of the device frame 3, and the two two-section drawer slides 4 are connected to their respective mounting plates 6. The slide mounting plates 6 are connected to the device frame 3 and the two-section drawer slides 4 by multiple first screws 9. This allows the keyboard drawer 1 to slide from the inside of the device frame 3 to the outside.
[0025] Specifically, the drawer limiting assembly includes a cabinet door rebounder 5, which is connected to the inside of the equipment frame 3 via a rebounder mounting plate 11. The rebounder mounting plate 11 is connected to the equipment frame 3 and the cabinet door rebounder 5 via multiple second screws 10.
