Hinge limiting device of door for vacuum furnace and hinge
The invention relates to a hinge limiting device of a door for a vacuum furnace and a hinge, and relates to the technical field of hinges, the hinge limiting device of the door for the vacuum furnace comprises a limiting plate and a limiting pin, the outer end of the limiting pin is sleeved with a limiting sleeve, and an elastic piece in a compressed state is arranged between the limiting pin and the limiting sleeve; the two ends of the elastic piece act on the limiting pin and the limiting sleeve correspondingly, an arc-shaped groove is formed in the limiting plate, the depth of the arc-shaped groove is gradually increased in the forming direction of the arc-shaped groove, and one end of the limiting pin abuts against the bottom wall of the arc-shaped groove and slides along the arc-shaped groove. In the process that the limiting groove slides from the bottom wall of the low end of the arc-shaped groove to the bottom wall of the high end, the limiting pin moves in the direction away from the limiting plate to enable the elastic piece to contract, the contracted elastic piece exerts pressure on the bottom wall of the arc-shaped groove so as to improve the friction force between the limiting rod and the bottom wall of the arc-shaped groove, and the hinge is limited through the action of the friction force; and when the limiting pin needs to be unlocked, the limiting pin slides reversely to complete unlocking, and the effect of higher safety performance is achieved.
本申请涉及一种真空炉用门的铰链限位装置及铰链，涉及铰链技术领域，一种真空炉用门的铰链限位装置包括限位板和限位销，限位销的外端套设有限位套，限位销与限位套之间设置有处于压缩状态的弹性件，弹性件的两端分别作用在限位销和限位套上，限位板上开设有弧形槽，弧形槽的深度沿着其开设方向逐渐增大，限位销的一端与弧形槽的底壁抵接并沿着弧形槽滑动。在限位槽从弧形槽低端的底壁滑动至高端的底壁处的过程中，限位销向远离限位板方向移动使弹性件收缩，收缩的弹性件向弧形槽底壁施加压力以提高限位杆与弧形槽底壁之间的摩擦力，通过摩擦力的作用对铰链进行限位，在限位销需要被解锁时，反向滑动限位销以完成解锁，具有安全性能更高的效果。
