Description

A heat-insulated and sealed commercial electric door Technical Field

[0001] This application relates to the technical field of doors and windows in construction, and in particular to a thermally insulated and sealed commercial electric door. Background Technology

[0002] To meet the demand for customer traffic and facilitate customer access to various budget hotels, convenience stores, pharmacies, and other shops, the entrances and exits of shops usually adopt convenient commercial doors.

[0003] Typical commercial doors are swing doors with two panels. The two panels are hinged to the door frame on opposite sides, and are installed vertically. A sealing strip is installed at the bottom of each panel, resting against the ground. A handle is located on the side of the panel furthest from the hinge, in the middle of the panel. To use the door, customers pull or push the handle, causing the door to rotate around the hinge axis and open, allowing customers to enter and exit the shop.

[0004] Because the sealing strip rubs against the ground repeatedly during the opening and closing of the door, the sealing strip is prone to wear, which reduces the sealing performance of the door and consequently reduces the heat insulation and sealing performance of the shop. Summary of the Invention

[0005] In order to improve the thermal insulation and sealing performance of commercial doors, this application provides a thermally insulated and sealed commercial electric door.

[0006] This application provides a heat-insulated and sealed commercial electric door, which adopts the following technical solution: A heat-insulated and sealed commercial electric door includes a door frame, a door leaf, a drive assembly, and a sealing assembly. The door frame is vertically arranged and fixedly connected to the wall. A hanging plate is provided at the top of the door frame. The door leaf is provided in two sets, each set including a fixed door leaf and a movable door leaf. Both the fixed door leaf and the movable door leaf are vertically arranged and adapted to the door frame. The fixed door leaf is fixedly connected to one side of the inner edge of the door frame, and the movable door leaf is connected inside the door frame. The movable door leaf and the fixed door leaf are arranged parallel to the inner edge of the door frame. The drive assembly is used to drive the movable door leaf to move. The sealing assembly is used to form a sealed state between the door leaf and the door frame, and between the fixed door leaf and the movable door leaf.

[0007] By adopting the above technical solution, the fixed door leaf is fixed inside the door frame, and the drive component drives the movable door leaf to move inside the door frame. When the fixed door leaf and the movable door leaf are in the closed state, the sealing component seals the overlapping position between the fixed door leaf and the movable door leaf, the connection between the fixed door leaf and the door frame, and the connection between the movable door leaf and the door frame. This makes it easy to seal the fixed door leaf and the movable door leaf with the door frame, thereby improving the heat insulation and sealing performance of the commercial door.

[0008] Optionally, the drive assembly includes a main board, a motor, and driven wheels. The main board is fixedly connected to the top of the door frame, the motor is fixedly connected to the mounting plate, and there are two driven wheels located at opposite ends of the main board. One of the driven wheels is coaxially and fixedly connected to the output shaft of the motor. The two driven wheels are fitted with a synchronous belt, and a hanging wheel is fixedly connected to the synchronous belt. The hanging wheel is connected to the top of the movable door leaf, and a guide wheel is provided at the bottom of the movable door leaf, which is tactilely connected to the door frame.

[0009] By adopting the above technical solution, the motor is started, the output shaft of the motor drives the driven wheel to rotate, the driven wheel drives the synchronous belt to rotate, the synchronous belt drives the hanging wheel to move, and the hanging wheel drives the movable door leaf to move, thus making the movable door leaf easy to move, thereby facilitating customers to enter and exit the shop.

[0010] Optionally, an automatic door sensor is fixedly connected to the top of the door frame. The automatic door sensor is electrically connected to a controller. The controller is electrically connected to a motor and fixedly connected to the door frame. The automatic door sensor is used to output microwave signals and infrared signals. The controller responds to the microwave signals and infrared signals emitted by the automatic door sensor and is used to control the direction of rotation of the motor output shaft.

[0011] By adopting the above technical solution, when a customer approaches the movable door, the automatic door sensor performs microwave and infrared scanning on the customer. The automatic door sensor outputs microwave and infrared signals to the controller, which controls the rotation direction of the motor, thereby making the movable door easy to open and close automatically, thus facilitating customers to enter and exit the shop.

[0012] Optionally, the sealing assembly includes sealing brushes, decorative sealing covers, airbag strips, and reinforcing parts. Two sets of sealing brushes are provided, one on the fixed door leaf and the other on the movable door leaf, respectively, and are positioned at their overlapping positions when the fixed and movable door leaves are closed. The two sets of sealing brushes are arranged along the height directions of the fixed and movable door leaves, respectively. Two decorative sealing covers are provided, each fixedly connected to the vertical side of the fixed and movable door leaves, and are positioned near their overlapping positions when the fixed and movable door leaves are closed. Sealing strips are provided between the two decorative sealing covers and the fixed and movable door leaves, respectively. The airbag strip is fixedly connected to the side of the movable door leaf away from the decorative sealing covers. The reinforcing parts are used to reinforce the seal between the movable door leaf and the door frame.

[0013] By adopting the above technical solution, the movable door leaf is moved, two sets of sealing brushes work together, the airbag strip is pressed against the door frame, and the reinforcing part strengthens the seal between the bottom of the movable door leaf and the door frame, thereby making it easier to seal between the fixed door leaf and the movable door leaf and the door frame, thus improving the heat insulation and sealing performance of the commercial door.

[0014] Optionally, the reinforcement section is provided in four groups, with each group divided into two pairs. Each pair of groups is located at the top and bottom of the door frame, with two groups located on either side of the hanging wheel and the other two groups located on either side of the guide wheel. The reinforcement section includes a heat insulation plate and a heat insulation seat. The heat insulation plate is fixedly connected to the door frame, and the heat insulation seat is fixedly connected to the movable door leaf. The heat insulation plate and the heat insulation seat are compatible. The heat insulation seat is hollow inside and allows air to flow. The heat insulation seat is made of elastic material. The bottom of the heat insulation seat protrudes towards the side away from the sealing brush on the movable door leaf. The heat insulation seat is connected to the airbag strip.

[0015] By adopting the above technical solution, the movable door leaf moves, and the protrusion of the heat insulation seat presses against the door frame, causing the heat insulation seat to be compressed. The air then compresses the heat insulation seat, which in turn compresses the heat insulation board. The air inside the airbag strip compresses the airbag strip, causing the airbag strip to press tightly against the door frame. This makes the movable door leaf less likely to slide and increases the sealing between the movable door leaf and the door frame, thereby easily improving the heat insulation and sealing performance of commercial doors.

[0016] Optionally, the bottom of the movable door leaf is also equipped with sealing brushes. There are two sets of sealing brushes, which are located on both sides of the heat insulation plate at the bottom of the movable door leaf and are both in interference contact with the ground.

[0017] By adopting the above technical solution, and by setting a sealing brush, the sealing brush can block air and external temperature, and add a sealing layer between the movable door leaf and the door frame, so that the sealing brush can easily seal the movable door leaf, thereby further enhancing the sealing performance between the movable door leaf and the door frame.

[0018] Optionally, both the fixed door leaf and the movable door leaf are fitted with glass, and glass sealing strips are installed between the fixed door leaf and the glass respectively.

[0019] By adopting the above technical solution and setting glass and glass sealing strips, the interior can easily receive sunlight and the fixed and movable doors are less prone to air leakage, thereby enhancing the heat insulation and sealing performance of the fixed and movable doors.

[0020] Optionally, both the fixed door leaf and the movable door leaf are equipped with mounting components. The mounting components include mounting bases, connecting grooves, and bolts. Multiple mounting bases are provided, and multiple mounting bases are respectively installed on the fixed door leaf and the movable door leaf. Two mounting bases are fixedly connected to the top and bottom of the fixed door leaf, respectively. Connecting grooves are opened in the mounting bases, and the connecting grooves correspond one-to-one with the bolts. The bolts pass through the mounting base located at the top of the fixed door leaf and are threadedly connected to the hanging plate. The bolts pass through the mounting base located at the bottom of the fixed door leaf and are threadedly connected to the door frame. The other two mounting bases are fixedly connected to the top and bottom of the movable door leaf, respectively. The mounting base located at the top of the movable door leaf is threadedly connected to the hanging wheel through the hanging plate. The mounting base located at the bottom of the movable door leaf is rotatably connected to the guide wheel.

[0021] By adopting the above technical solution, and by setting fixing seats on the fixed door leaf and the movable door leaf respectively, it is easy for operators to assemble the fixed door leaf and the movable door leaf with bolts, thereby reducing the labor intensity of operators.

[0022] Optionally, the door frame is made of thickened thermally broken aluminum alloy profiles.

[0023] By adopting the above technical solution and using thickened aluminum alloy profiles with thermal break, the range of motion of the movable door can be expanded while meeting the requirements of thermal insulation, thus easily meeting the requirements of strength and weight, and thus simultaneously meeting the needs of various places for entry and exit and the flow of people.

[0024] In summary, this application includes at least one of the following beneficial technical effects: by setting sealing brushes, decorative sealing covers, airbag strips, heat insulation boards, and heat insulation seats, the sealing performance between the fixed door leaf and the movable door leaf and the door frame is easily enhanced, thereby easily improving the heat insulation and sealing performance of the commercial door; by setting motors, driven wheels, synchronous belts, hanging wheels, guide wheels, automatic door sensors, and controllers, the movable door leaf can easily identify customers, thereby making it easy for the movable door leaf to open and close automatically, thus facilitating customers to enter and exit the shop; by setting door frames, door leaves, fixing seats, and bolts, operators can easily fix and install the door leaves, thereby easily reducing the labor intensity of operators.

[0047] In use, the movable door leaf 22 is moved so that it is closed to the fixed door leaf 21. The protrusion of the heat insulation seat 542 presses against the door frame 1, causing the heat insulation seat 542 to be compressed. Air compresses the heat insulation seat 542, which in turn compresses the heat insulation plate 541. The air inside the airbag strip 53 compresses the airbag strip 53, making the airbag strip 53 between the two movable door leaves 22 tightly abut against each other. This makes the movable door leaf 22 less likely to slide and increases the sealing between the movable door leaf 22 and the door frame 1, thereby improving the heat insulation and sealing performance of the commercial door.

[0048] The implementation principle of a heat-insulated and sealed commercial electric door according to an embodiment of this application is as follows: Bolt 33 connects the fixing seat 31 to the door frame 1. The motor 42 is started, and the automatic door sensor 422 performs microwave and infrared scanning on the customer. The automatic door sensor 422 outputs microwave and infrared signals to the controller 421. The controller 421 controls the rotation direction of the motor 42. The output shaft of the motor 42 drives the driven wheel 43 to rotate. The driven wheel 43 drives the synchronous belt 44 to rotate. The synchronous belt 44 drives the hanging... As the wheel 45 moves, the hanging wheel 45 drives the movable door leaf 22 to move. The protrusion of the heat insulation seat 542 presses against the door frame 1, causing the heat insulation seat 542 to be compressed. Air compresses the heat insulation seat 542, and the heat insulation seat 542 compresses the heat insulation plate 541. The air in the airbag strip 53 compresses the airbag strip 53, making the airbag strip 53 between the two movable door leaves 22 tightly abut against each other. This makes the movable door leaf 22 less likely to slide and increases the sealing between the movable door leaf 22 and the door frame 1, thereby improving the heat insulation and sealing performance of the commercial door.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
