一种可折叠的3d打印机

Foldable 3D printer

Abstract

本发明涉及一种可折叠的3D打印机,包括上箱体、下箱体、打印装置和折叠机构;折叠机构由Z轴主固定座、圆柱销、拨销、弹簧、定位杆、Z轴传动固定座、Z轴转子固定座及旋转轴组成,Z轴传动固定座内设有导槽,圆柱销一端插入Z轴主固定座的固定孔内,另一端插设在导槽内并套设在定位杆上,定位杆设置在导槽内的部分套设有弹簧,弹簧一端抵接在导槽内,另一端抵接在圆柱销上,圆柱销与定位杆对应设有销孔,销孔与拨销套接。本发明的可折叠的3D打印机可简单便捷的折叠,使其不使用时的体积大大缩小,减少了占地面积,且便于携带及存放;通过圆柱销结构,减少运输时的晃动,增加了机器折叠时的稳定性。
The invention relates to a foldable 3D printer. The 3D printer comprises an upper box body, a lower box body, a printing device and a folding mechanism. The folding mechanism is composed of a Z-axis main fixing seat, a cylindrical pin, a shifting pin, a spring, a positioning rod, a Z-axis transmission fixing seat, a Z-axis rotor fixing seat and a rotary shaft, and a guide groove is formed in the Z-axis transmission fixing seat; one end of the cylindrical pin is inserted into a fixing hole of the Z-axis main fixing seat, and the other end of the cylindrical pin is inserted into the guide groove and arranged on the positioning rod in a sleeving mode; the part, arranged in the guide groove, of the positioning rod is sleeved with the spring, one end of the spring is connected into the guide groove in an abutting-against mode, and the other end of the spring is connected onto the cylindrical pin in the abutting-against mode; and a pin hole is formed in the position, corresponding to the positioning rod, of the cylindrical pin, and the shifting pin is sleeved with the pin hole. The foldable 3D printer can be folded in an easy, convenient and rapid mode, the size of the foldable 3D printer during nonuse is greatly reduced, the occupied area is reduced, and the foldable 3D printer is convenient to carry and store; and through the cylindrical pin structure, waggling during transporting is reduced, and stability during machine folding is improved.
