Description

Low threshold

Technical Field

The utility model belongs to the door and window field relates to a low threshold, especially relates to an outer division is gone into low threshold for supporting of door.

Background

The outward opening door needs a doorsill and a door frame in order to ensure sealing performance. The outward opening door is in lap joint sealing with the three sides of the door frame, and the door leaf is in lap joint sealing with the lower doorsill, so that the periphery of the door can be sealed. The existing entrance door mostly uses the threshold with a certain height higher than the indoor and outdoor ground, and if accumulated water exists outside the room, the water is not easy to enter the room because the threshold is higher than the ground. However, the threshold often protrudes one piece of ground from the appearance, so that the appearance is influenced; if water enters the room, the water cannot be discharged outdoors, and only the water can be sucked dry by rags or sponges. Therefore, people start to develop a novel low doorsill buried underground continuously in recent years, but the low doorsill is usually sealed only by wool tops, the sealing performance is poor, and the doorsill is easy to accumulate water.
