The utility model discloses a support hinge for the door cover of a laser engraving machine, which comprises a body. The top of the body is movably connected with the door cover through a rotating shaft, and its features are as follows: the door cover is connected with an internal hinge of the body; in the implementation of the utility model, when a worker lifts the door cover, the telescopic column pulls out the sleeve, and the first air hole is sealed by the base tube under the action of the first spring. Therefore, after the outside gas enters the sleeve, it is no longer excluded; after the staff release the door cover, because the one-way valve does not discharge gas outward, and the first air hole is blocked, the internal gas supports the expansion column, which shows that the hinge supports the door cover to open; when the door cover is pressed by force, the weight of the door cover plus the downward pressure exerted by the hand, the first spring is compressed, and the sleeve is inserted at the bottom of the base cylinder. The second stomata is connected with the first stomata, and the gas in the sleeve is discharged. The telescopic column enters the sleeve and can close the door cover. After lifting the door cover, no additional support rod is needed.

一种激光雕刻机门盖支撑铰链
本技术涉及激光雕刻机辅助设备领域,具体涉及一种激光雕刻机门盖支撑铰链。
技术介绍
激光雕刻加工是利用数控技术为基础,激光为加工媒介。加工材料在激光照射下瞬间的熔化和气化的物理变性,达到加工的目的。激光雕刻之前放置板材以及加工完成之后取出板材清理残渣检修设备都需要打开门盖,传统的门盖打开之后需要使用支撑杆撑起门盖,影响操作人员的操作。
技术实现思路
本技术的目的在于克服现有技术中存在的上述问题,提供一种激光雕刻机门盖支撑铰链,抬起门盖之后不需要额外的支撑杆支撑。为实现上述技术目的,达到上述技术效果,本技术是通过以下技术方案实现:一种激光雕刻机门盖支撑铰链,包括机体,所述机体顶部通过转轴活动连接门盖,其特征在于:所述门盖与机体内部连接有铰链;所述铰链两端分别与门盖内侧以及机体内壁铰接,铰链包括底座筒,底座筒开口端插接有套筒,套筒内部设置有活塞,活塞外侧固定有伸缩柱,活塞还贯穿有向下单向排气的单向气阀,套筒底端连接且抵接有第一弹簧;所述套筒底部设置有第一气孔,所述底座筒内腔底部固定有第一阻挡块,所述套筒底端与第一阻挡块抵接位置,底座筒侧壁对应第一气孔 ...
