Room door adjustable in opening degree

Abstract

The invention provides a room door adjustable in opening degree in order to solve the problem that a room door cannot be fixed to any opening angle and meet the using requirement of people. The room door adjustable in opening degree comprises a door plate and a door frame; one side of the door plate is connected with the door frame through a rotating shaft, so that the door plate can rotate aroundthe rotating shaft; the room door adjustable in opening degree is mainly characterized in that an upper cross beam of the door frame is provided with an arc-shaped strip protruding in the opening direction of the room door; the arc-shaped strip uses the rotating shaft as a circle center, and a plurality of concave parts are arranged on the bottom face of the arc-shaped strip; elastic convex partsare arranged on the upper portion of the door plate; and in the opening process of the door plate, the convex parts stretch upward into the concave parts of the arc-shaped strip. Because the arc-shaped strip uses the rotating shaft as the circle center, in the process that the door plate rotates around the rotating shaft, the running trajectory of the convex parts corresponds to the arc-shaped strip, the convex parts stretch upwards into the concave parts of the arc-shaped strip, and therefore a resisting force is formed for rotating of the door plate, and only under the effect of the external force, the convex parts can be pressed downwards to disengage from the concave parts, so that the door plate can continuously rotate around the rotating shaft.

Description

technical field [0001] The invention relates to a door for a building. Background technique [0002] The traditional door is only connected to the door frame through hinges, rotating shafts, etc. The door can rotate freely, and it is difficult to fix it at a predetermined angle, which is inconvenient in use. For example, sometimes people just want to open the door a crack , indicating that the door is not locked, and at the same time, people who do not want to see the indoor situation easily, and sometimes people want to open the door halfway to achieve proper ventilation. [0003] In order to solve the above problems, the utility model patent No. 201120313285.6 discloses a fixed door, which mainly solves the problem that the door cannot be fixed at any opening angle. It includes a door main body, a door lock is provided on the side of the door main body, the door lock is connected with a rotary handle, a vertical shaft sleeve is provided on the inner side of the door main ...
