Description

An electric swing door that can be opened in two directions

technical field

The invention relates to a side-hung door, in particular to an electric side-hung door capable of bidirectional opening.

Background technique

Swing doors can be divided into electric swing doors and hand push swing doors according to whether they are electrically controlled. Most of the swing doors are hand push swing doors. One-sided opening is realized. Also have a kind of vertical hinged door that floor spring is installed, can realize two-way opening, vertical hinged door relies on spring recovery force to close automatically. There is also a kind of electric swing door, which can realize one-way opening, but cannot realize the function of two-way opening, and it is troublesome to install at the same time.

Contents of the invention

The technical problem to be solved by the present invention is to provide an electric side-hung door that can be opened in both directions and is easy to install.

The technical solution adopted by the present invention to solve the above technical problems is: an electric swing door that can be opened bidirectionally, including a door body and a power control device, the power control device includes a motor and a control circuit, and the motor and the The control circuit is connected, the output shaft of the motor extends downwards and is fixed to the upper end of the door body, the lower end of the door body is provided with a shaft hole, and the shaft with a height adjustment device extends upwards and is fixed on the upper end of the door body. In the shaft hole, the output shaft of the motor is on the same axis as the rotating shaft and is located on one side of the door body.

The height adjustment device includes a sinking box, the height adjustment assembly and the lifting platform are arranged in the sinking box, the lifting platform is arranged on the height adjustment assembly, and the outside of the lifting platform is arranged There is a vertical guiding mechanism, a pressure bearing is arranged inside the lifting platform, and the rotating shaft is arranged on the pressure bearing. Operating the height adjustment assembly, the lifting platform can move up and down, and the pressure bearing can bear the weight of the door body.

The height adjustment assembly includes a fixed block, a slide block, an adjustment screw and a support plate, the fixed block is arranged in the ground box, the support plate is vertically arranged beside the fixed block, and the support plate A narrow and long through hole in the vertical direction is provided, the upper end surface of the fixed block is a first inclined surface, the lower end surface of the slider is a second inclined surface, and the first inclined surface of the fixed block is set There is a dovetail groove, the second inclined surface of the slider is provided with a projection that fits with the shape of the dovetail groove, the slider can move on the fixed block, and the slider The upper end surface is a plane, and a threaded hole is provided in the slider, and the adjusting screw passes through the long and narrow through hole on the support plate to cooperate with the threaded hole, and the lifting platform is arranged on the slider. on the block. Turn the adjusting screw, the slider moves on the fixed block, and adjust the height of the lifting platform.

The vertical guide mechanism includes a vertical guide groove and a guide block arranged on the outside of the lifting platform, the guide block is fixed on the support plate by screws, and the guide block is located in the vertical guide groove. In order to ensure that when the lifting platform moves up and down, it maintains verticality and does not deviate from the center position. Due to the relatively small wall thickness of the sinking box and the thickness of the intermediate partition, deformation will occur after welding, and the verticality and parallelism of the fit cannot be guaranteed, resulting in the guide mechanism not working properly, so bolts are used to fix it.

When the slider is located at the uppermost end of the fixed block, the slider is located directly below the lifting platform. When the slider slides to the highest point, it is just at the center of the lifting platform, so that it can fully support the lifting platform, which will not cause uneven force on the slider and prolong the service life.

A skeleton oil seal is installed above the bearing. Prevent foreign matter from entering the pressure bearing.

The lower end of the door body is fixedly provided with a support rocker, and the shaft hole is arranged on the support rocker.

It also includes a first sensor and a second sensor, the first sensor is connected to the control circuit, the second sensor is connected to the control circuit, the first sensor is located on one side of the door body, The second sensor is located on the other side of the door body. After the sensor senses the human body, the control circuit sends a signal to the motor, and the motor rotates forward (reversely) to realize the two-way opening of the translation door.

The ground sinking box includes a bottom box and a cover plate, and the rotating shaft passes through the cover plate.

Compared with the prior art, the present invention has the advantage that the motor output shaft and the rotating shaft are respectively located at the upper and lower ends of the door body and are on the same axis, the control circuit drives the motor to rotate forward (reversely), and the motor output shaft drives the door body inward ( Outside) to open, realize the two-way opening of the door body, and at the same time, the height of the rotating shaft at the lower end of the door body can be adjusted, which facilitates the installation of the door body.
