Description

Technical Field

[0001] This utility model relates to the technical field of printer base assembly, specifically a spring-loaded buffer base assembly for printers. Background Technology

[0002] Printers can print various text documents such as contracts, reports, resumes, papers, and letters, meeting the needs of daily office work, study, and personal record keeping. As the core component supporting the whole machine, the structural design of the printer base assembly directly affects the stability and functionality of the device.

[0003] Current printer base assemblies often only provide support and simple cushioning for the printer. Considering that the printing process generates vibrations from multiple directions, poor cushioning and shock absorption can affect stability and, consequently, print quality. Therefore, we propose a new type of spring-cushioned printer base assembly. Utility Model Content

[0004] The purpose of this invention is to provide a spring-loaded base assembly for printers to solve the problems of insufficient stability and inadequate cushioning and protection mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spring-loaded base assembly for a printer, including a lower base, an upper base connected to the top of the lower base, vertical composite springs evenly installed between the upper and lower bases, reinforcing ribs evenly connected to the vertical composite springs, U-shaped limiting components evenly installed at the bottom edge of the upper base, and limiting slide rods evenly installed at the top edge of the lower base, with sliding sleeves slidably connected to the U-shaped limiting components at both ends of the top of the limiting slide rods, a viscous damper installed between the limiting slide rods and the lower base, quick-release pressure plates slidably connected to both ends of the top of the upper base, a first horizontal rubber pad installed at one end of the quick-release pressure plate by screws, a horizontal spring and a second horizontal rubber pad sequentially connected to the first horizontal rubber pad, an adjusting slider at the bottom of the quick-release pressure plate, and an adjusting cavity on the upper base, with locking screw holes evenly arranged inside the adjusting cavity to match the adjusting slider.

[0006] As a further technical solution of this utility model, a fixed suction cup is installed at each of the four corners of the bottom of the lower base, and the bottom of the fixed suction cup is uniformly provided with suction holes.

[0007] As a further technical solution of this utility model, four fixed suction cups are provided, and air guide tubes are connected between adjacent fixed suction cups.

[0008] As a further technical solution of this utility model, a manual air valve is provided on one side of the air guide tube assembly, and a reserved air hole is provided on the manual air valve.

[0009] As a further technical solution of this utility model, the top and bottom of the vertical composite spring are respectively provided with matching mounting strips for the upper base and the lower base, and screws are provided between the upper base and the mounting strips for both the upper base and the lower base.

[0010] As a further technical solution of this utility model, the output end of the viscous damper is provided with a piston assembly connected to the limiting slide rod, and the bottom of the piston assembly is uniformly provided with energy dissipation holes.

[0011] As a further technical solution of this utility model, the limiting slide bar, the viscous damper and the U-shaped limiting component are all provided with assembly pins that engage with the upper base and the lower base, and screws are provided between the upper base and the assembly pins respectively.

[0012] As a further technical solution of this utility model, an anti-slip silicone layer is adhered to the middle position of the top of the upper base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By incorporating a lower base, the device optimizes its structure. Firstly, it transforms the common single-base assembly of a printer into a composite structure consisting of a lower and upper base. A vertical composite spring-based elastic buffer structure, along with a vertical telescopic movement structure comprised of a sliding sleeve-type limiting rod and a U-shaped limiting member, is evenly installed between the lower and upper bases. This absorbs vertical vibrations during printing. Furthermore, a viscous damper installed between the limiting rod and the lower base ensures that when the device experiences vertical displacement due to printing vibrations, it drives the piston assembly within the damper's cylinder. The viscous oil in the cylinder generates heat through friction as it passes through the piston assembly's energy-dissipating holes, converting the vibrational mechanical energy into internal energy, which is then used for composite... The vertical displacement guiding structure, spring buffer structure, and energy dissipation structure enable the device to achieve a highly efficient buffering and vibration protection effect. On the other hand, the user can place the printer on the top of the upper base and then use the sliding connection structure composed of the adjusting cavity and adjusting slider to change the horizontal position of the two quick-release pressure plates. This causes the second horizontal rubber pad on the quick-release pressure plate to compress the horizontal spring and press it tightly against the outer wall of the printer. The preload of the horizontal spring improves the firmness of the printer during installation. Furthermore, the three-level elastic buffer structure composed of the horizontal spring, the second horizontal rubber pad, and the first horizontal rubber pad can buffer the horizontal vibration generated by the printer, thereby achieving comprehensive buffering protection for the vertical and horizontal positions of the printer.

[0015] By incorporating fixed suction cups, the device optimizes its structure. Firstly, users can move the device to a suitable work surface, open the manual air valve, and inflate the air guide tube assembly through the pre-drilled air holes. This draws out the gas from the four fixed suction cups, creating negative pressure that firmly adheres to the work surface, allowing for non-destructive and flexible installation with broad applicability. Secondly, the interlocking structure between the upper and lower bases and the assembly inserts, combined with screw locking, allows for independent disassembly and replacement of the vertical composite spring components. Furthermore, by providing assembly pins on the limiting slide rod, viscous damper, and U-shaped limiting component that engage with the upper and lower bases, and with screw locking, the limiting slide rod, viscous damper, and U-shaped limiting component can be disassembled and assembled on the upper and lower bases. This modular design and replaceable buffer components enhance the device's modularity and extend its service life. 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-5 An embodiment of this utility model is provided: a spring-buffered base assembly for a printer, including a lower base 8, an upper base 7 connected to the top of the lower base 8, a vertical composite spring 6 evenly installed between the upper base 7 and the lower base 8, and reinforcing ribs 19 evenly connected to the vertical composite spring 6.

[0024] U-shaped limiting parts 5 are evenly installed at the bottom edge of the upper base 7, and limiting slide rods 13 are evenly installed at the top edge of the lower base 8. Both ends of the top of the limiting slide rods 13 are provided with sliding sleeves 16 that are slidably connected to the U-shaped limiting parts 5. A viscous damper 17 is installed between the limiting slide rods 13 and the lower base 8.

[0025] The output end of the viscous damper 17 is provided with a piston assembly 14 connected to the limiting slide bar 13, and the bottom of the piston assembly 14 is uniformly provided with energy dissipation holes.

[0026] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, by setting the common single base assembly of a printer as a composite structure consisting of a lower base 8 and an upper base 7, and evenly installing a vertical composite spring 6 between the lower base 8 and the upper base 7 to form an elastic buffer structure, and a vertical telescopic movement structure consisting of a limiting slide rod 13 with a sliding sleeve 16 and a U-shaped limiting member 5, vertical vibrations during the printing process can be absorbed. In addition, with the viscous damper 17 installed between the limiting slide rod 13 and the lower base 8, when the device generates vertical displacement due to printing vibration, it drives the piston assembly 14 to move inside the cylinder of the viscous damper 17. When the viscous oil in the cylinder passes through the energy dissipation hole of the piston assembly 14, friction generates heat, which can convert the mechanical energy of vibration into internal energy. Thus, through the composite vertical displacement guiding structure, spring buffer structure and energy dissipation structure, the device achieves a highly efficient buffering and vibration protection effect.

[0027] Both ends of the top of the upper base 7 are slidably connected to quick-release pressure plates 4. One end of the quick-release pressure plate 4 is fitted with a first horizontal rubber pad 1 by screws. A horizontal spring 3 and a second horizontal rubber pad 2 are connected to the first horizontal rubber pad 1 in sequence. An adjustment slider 20 is provided at the bottom of the quick-release pressure plate 4. An adjustment slide cavity 21 is provided on the upper base 7. Locking screw holes 22 that match the adjustment slider 20 are evenly arranged inside the adjustment slide cavity 21.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 5As shown, the user can place the printer on top of the upper base 7, and then use the sliding connection structure formed by the adjusting slide cavity 21 and the adjusting slider 20 to change the horizontal position of the two quick-release pressure plates 4. This causes the second horizontal rubber pad 2 on the quick-release pressure plate 4 to compress the horizontal spring 3 and press it against the outer wall of the printer. The preload of the horizontal spring 3 improves the firmness of the printer during installation. Furthermore, the three-level elastic buffer structure formed by the horizontal spring 3, the second horizontal rubber pad 2, and the first horizontal rubber pad 1 can buffer the horizontal vibration generated by the printer, thus optimizing the buffer protection effect.

[0029] A fixed suction cup 9 is installed at each of the four corners of the bottom of the base 8, and suction holes are evenly arranged on the bottom of each fixed suction cup 9.

[0030] There are 4 fixed suction cups 9, and air guide tubes 10 are connected between adjacent fixed suction cups 9;

[0031] A manual air valve 11 is provided on one side of the air pipe assembly 10, and a reserved air hole 23 is provided on the manual air valve 11.

[0032] The top and bottom of the vertical composite spring 6 are respectively provided with matching mounting strips 18 for the upper base 7 and the lower base 8, and screws are provided between the upper base 7 and the lower base 8 and the mounting strips 18.

[0033] The limiting slide bar 13, the viscous damper 17 and the U-shaped limiting piece 5 are all provided with mounting pins 15 that engage with the upper base 7 and the lower base 8. Screws are provided between the upper base 7 and the lower base 8 and the mounting pins 15 respectively.

[0034] An anti-slip silicone layer 12 is adhered to the middle position of the top of the upper base 7.

[0035] Working principle: In use, the user first moves the device to a suitable work surface, then opens the manual air valve 11, and inflates the air pipe assembly 10 through the reserved air hole 23. This causes the gas inside the four fixed suction cups 9 connected to it to be extracted, creating negative pressure and firmly adhering to the corresponding work surface. This allows for non-destructive and flexible installation of the device, making it highly adaptable. Furthermore, by setting the common printer single base assembly as a composite structure consisting of a lower base 8 and an upper base 7, and evenly installing a vertical composite spring component 6 between the lower base 8 and the upper base 7 to form an elastic buffer structure, as well as a limiting mechanism with a sliding sleeve 16, the device achieves this. The vertical telescopic movement structure composed of the sliding rod 13 and the U-shaped limiting member 5 can absorb vertical vibrations during the printing process. Combined with the viscous damper 17 installed between the limiting rod 13 and the lower base 8, when the device experiences vertical displacement due to printing vibrations, it drives the piston assembly 14 to move inside the cylinder of the viscous damper 17. The viscous oil in the cylinder generates heat through friction as it passes through the energy dissipation hole of the piston assembly 14, converting the mechanical energy of the vibration into internal energy. Through the composite vertical displacement guiding structure, spring buffer structure, and energy dissipation structure, the device achieves a highly efficient buffering and vibration-damping protection effect. Simultaneously, the user can... The printer is placed on top of the upper base 7. Then, using the sliding connection structure formed by the adjusting slide cavity 21 and the adjusting slider 20, the horizontal position of the two quick-release pressure plates 4 is changed. This causes the second horizontal rubber pad 2 on the quick-release pressure plate 4 to compress the horizontal spring 3 and press it tightly against the outer wall of the printer. The preload of the horizontal spring 3 enhances the secure installation of the printer. Furthermore, the three-stage elastic buffer structure composed of the horizontal spring 3, the second horizontal rubber pad 2, and the first horizontal rubber pad 1 can buffer the horizontal vibrations generated by the printer, thus achieving comprehensive buffering of the printer's vertical and horizontal positions. Furthermore, on the one hand, by utilizing the plug-in structure between the upper base 7, the lower base 8, and the assembly insert 18, and with the locking and fixing effect of screws, the vertical composite spring component 6 can be independently disassembled and replaced. On the other hand, by providing assembly clips 15 on the limiting slide rod 13, the viscous damper 17, and the U-shaped limiting component 5 that engage with the upper base 7 and the lower base 8, and with the locking and fixing effect of screws, the limiting slide rod 13, the viscous damper 17, and the U-shaped limiting component 5 can be disassembled and assembled on the upper base 7 and the lower base 8. This enables the device to achieve the advantages of modularity and replaceable buffer components, which is beneficial to extending its service life.
