[0002] In the current prior art, it generally includes a printer body, and a base body is fixedly installed at the bottom of the printer body, and a threaded rod is movably installed inside the base body. For this adjustable printer base, a motor can drive the threaded rod inside the base body to rotate. The threaded rod is assisted and supported by a limiting plate. Two threaded blocks on the threaded rod move away from each other under the threaded thrust, driving the guide wheels to roll along the guide grooves on the movable plate, and at the same time, they also move away from each other along the two inclined surfaces of the groove, so that the movable plate moves downward under the reaction force. The movable plate then drives the support rod to move inside the through hole at the bottom of the base body. By using the reaction force of the support rod and the support block on the ground, the base body is lifted, thereby realizing the adjustment of the height of the base body to adapt to users of different heights and desktops of different heights, achieving the purpose of convenient adjustment.

[0003] However, the prior art still has deficiencies, such as the following aspects:

[0004] The existing adjustable base for a printer has a simple structure. Especially for industrial printers, their large size makes it inconvenient to adjust. Moreover, the chassis and the bottom of the printer are basically fixedly installed on the lower surface, resulting in poor ventilation effect. In addition, the simple structure of the printer base lacks functional effects. Summary of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0021] As Figures 1 - 4 shown, an adjustable base for a printer includes an adjustment structure 1. An outer wall inside the adjustment structure 1 is fixedly installed with a heat dissipation structure 2. The adjustment structure 1 includes a base frame 11 fixedly installed on the outer wall of the heat dissipation structure 2. The heat dissipation structure 2 includes a heat dissipation bottom plate 21 fixedly installed on the inner side outer wall of the base frame 11. A rotating handle 12 is rotatably connected to the outer wall of the front surface of the base frame 11. One end of the rotating handle 12 located inside the base frame 11 is fixedly installed with a first bevel gear 121. A fixing block 13 is fixedly installed outside the inside of the base frame 11. A rotating rod 14 is rotatably connected to the inner side of the outer wall of the fixing block 13. The outer wall of the first bevel gear 121 meshes with a second bevel gear 141 on the outer wall of the rotating rod 14. The outer wall of the first bevel gear 121 meshes with the outer wall of the second bevel gear 141. Third bevel gears 142 are fixedly installed at both ends of the rotating rod 14.

[0022] It should be noted that in this embodiment, by manually rotating the rotating handle 12, the rotating handle 12 drives the first bevel gear 121 to rotate. Then, the outer wall of the first bevel gear 121 drives the second bevel gear 141 to mesh, thereby driving the rotating rod 14 to rotate. When the rotating rod 14 rotates, the third bevel gears 142 on the outer walls at both ends mesh with the outer wall of a fourth bevel gear 151 fixedly sleeved on the outer wall of a bidirectional threaded rod 15.

[0023] As Figure 1 、 Figure 2 、 Figure 4 shown, heat dissipation bottom plates 21 are fixedly installed on the outer walls on both sides of the base frame 11. A protective frame 22 is fixedly installed on the top of the heat dissipation bottom plate 21. A filter screen 23 is fixedly installed on the inner side of the top of the protective frame 22. A fan frame 24 is fixedly installed on the inner side outer wall of the heat dissipation bottom plate 21. A fan motor 25 is fixedly installed on the outer wall of the bottom of the fan frame 24. One end at the top of the fan motor 25 is drivingly connected to a fan blade 26.

[0024] It should be noted that in this embodiment, since the heat dissipation bottom plate 21 is installed inside the base frame 11, after the bottom of the printer is installed, the fan motor 25 fixedly installed on the fan frame 24 can be started. The outer wall of one end at the top of the fan motor 25 drives the fan blade 26 to rotate, generating wind. The fan blade 26 passes through the filter screen 23 to dissipate heat inside the printer, and the filter screen 23 can also filter and reduce the dust blown into the printer from the bottom inside the base frame 11.

[0025] As Figures 1 - 3 shown, on the left and right sides inside the base frame 11, there are rotatably connected two-way threaded rods 15. A fourth bevel gear 151 is fixedly sleeved on the outer wall of the two-way threaded rod 15. The outer wall of the fourth bevel gear 151 meshes with the outer wall of a third bevel gear 142. A threaded support block 152 is threadedly connected to the outer wall of the two-way threaded rod 15. Inside the top of the threaded support block 152, there is a rotatably connected push rod 153. One end of the push rod 153 is rotatably connected to a base mounting block 154.

[0026] It should be noted that in this embodiment, the outer wall of the third bevel gear 142 meshes with the fourth bevel gear 151 sleeved on the outer wall of the two-way threaded rod 15, thereby driving the two-way threaded rod 15 to rotate. Then, the rotation of the two-way threaded rod 15 drives the threaded support block 152 on its outer wall to perform threaded rotation. The thread on the outer wall of the two-way threaded rod 15 is a double thread. Thus, the push rods 153 inside the top of the two threaded support blocks 152 squeeze the base mounting block 154. When installing the base mounting block 154, the four base mounting blocks 154 are installed at the four corners of the printer base. Therefore, the printer can be pushed up and down by the push rods 153.

[0027] The working principle of the present utility model: By manually rotating the rotating grip 12, the rotating grip 12 drives the first bevel gear 121 to rotate. Then, the outer wall of the first bevel gear 121 drives the second bevel gear 141 to mesh, thereby driving the rotating rod 14 to rotate. When the rotating rod 14 rotates, the third bevel gears 142 on the outer walls at both ends mesh with the outer walls of the fourth bevel gears 151 fixedly sleeved on the outer wall of the two-way threaded rod 15.

[0028] The outer wall of the third bevel gear 142 meshes with the fourth bevel gear 151 sleeved on the outer wall of the two-way threaded rod 15, thereby driving the two-way threaded rod 15 to rotate. Then, the rotation of the two-way threaded rod 15 drives the threaded support block 152 on its outer wall to perform threaded rotation. The thread on the outer wall of the two-way threaded rod 15 is a double thread. Thus, the push rods 153 inside the top of the two threaded support blocks 152 squeeze the base mounting block 154. When installing the base mounting block 154, the four base mounting blocks 154 are installed at the four corners of the printer base. Therefore, the printer can be pushed up and down by the push rods 153.

[0029] Then, the heat dissipation bottom plate 21 is installed on the inner side of the base frame 11. After the bottom of the printer is installed, the fan motor 25 fixedly installed on the fan bracket 24 can be started. The outer wall at one end of the top of the fan motor 25 drives the fan blade 26 to rotate, generating wind, and the fan blade 26 passes through the filter screen 23 to dissipate heat from the inside of the printer. The filter screen 23 can also filter and reduce the dust blown into the printer from the bottom of the inner side of the base frame 11.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
