Door capable of reminding deformation

Abstract

The invention discloses a door capable of reminding deformation. The door comprises a door frame and a door leaf hinged to one side of the door frame; a first hinge and a second hinge are fixed to oneside of the door frame and one side of the door leaf in a threaded mode correspondingly; a sleeve column is welded to the side, close to the door leaf, of the first hinge; a rotating shaft is weldedto the top end of the sleeve column; a sleeve rotatably sleeves the outer side of the rotating shaft; the outer side of the sleeve is welded to the side, close to the door frame, of the second hinge;a lug plate is welded to one side of the door frame and located over the first hinge; a groove is formed in one side of the lug plate; a screw rod is mounted on the rotating shaft in a threaded mode;and one end of the screw rod extends to the outer side of the rotating shaft, and a rotary knob is welded to one end of the screw rod. During deformation, the rotating shaft drives a sliding plate tomove, thus a first copper sheet on the sliding plate moves to make contact with the positive electrode of a battery, a buzzer gives sound to alarm to remind people to replace the hinges in time, the battery is conveniently replaced, and using is facilitated.

Description

technical field [0001] The invention relates to the field of door leaf technology, in particular to a door that is deformed and reminded. Background technique [0002] The structure of the door mainly includes a door frame and a door leaf, and the door leaf is connected to the door frame through a hinge. Since the door leaf is in a suspended state for a long time during use, the hinge needs to bear a relatively large force, so the hinge is prone to deformation during the use of the door leaf. [0003] After retrieval, the patent document with application number 201710214757.4 discloses a door that is deformed to remind, including a door frame, a door leaf and a hinge. The hinge includes a first leaf, a second leaf and a mandrel; the first leaf is fixed to the door leaf Connection, the mandrel is fixedly connected with the first leaf, the connecting end of the mandrel faces down, a sleeve is fixed on the second leaf, the opening of the sleeve faces upward, the connecting end...

AI Technical Summary

Problems solved by technology

[0004] In view of the above problems, the present invention provides a door for reminding of deformation. This door can effectively solve the problem in the background technology that the hinge deformation cannot be alarmed. It can sound an alarm in time when the hinge is deformed and bent, and it is convenient to replace a new battery. , improve the alarm effect
