Abstract
Description
Technical Field
[0001] The present invention relates to a heavy-duty French door, and more particularly to an automatic opening and closing device for a heavy-duty French door. Background Art
[0002] A French door refers to a door with hinges installed on the side of the door, opening inward (left inward opening, right inward opening) or outward (left outward opening, right outward opening). It consists of a door frame, hinges, a door leaf, a lock, etc. French doors include single-leaf doors and double-leaf doors. When opening a French door, it is often necessary to rotate the French door so that the door frame on the outside of the French door is in an open state. When it is necessary to rotate the French door inward to open the door frame, at this time, the French door rotates into the interior of the building. When there are a lot of sundries stacked inside the building, it will affect the opening process when the French door rotates.
[0003] The existing structure of French doors is relatively simple. French doors can only be rotated to open and are difficult to perform a lateral pulling process, making it difficult to expand the size of the access passage during the opening process of French doors. Therefore, there are limitations, especially in some factories, experimental sites, etc.; and French doors are prone to dust accumulation outdoors, resulting in affected smoothness, that is, the maintenance cycle is shortened.
[0004] In view of this, the present invention designs an automatic opening and closing device for a heavy-duty French door. Summary of the Invention
[0005] The main purpose of the present disclosure is to provide an automatic opening and closing device for a heavy-duty French door to effectively solve the problems raised by the inventor in the above background art.
[0006] To achieve the above object, the technical solution adopted by the present invention is as follows:
[0007] An automatic opening and closing device for a heavy-duty French door includes an opening and closing track, a flat-pushing track, a French door main body, and a cleaning mechanism. There are two opening and closing tracks, which are oppositely arranged. The flat-pushing track is detachably installed between the two opening and closing tracks. Active moving platforms are slidably installed on both of the two opening and closing tracks. The French door main body is fixedly installed on the top of the active moving platform, that is, the two French door main bodies are oppositely arranged. One side of the two French door main bodies that are close to each other is slidably connected to the flat-pushing track. A cleaning mechanism is provided on the side of the active moving platform, and the cleaning mechanism is used to clean the opening and closing track;
[0008] The French door main body is composed of a door frame, connecting hinges, and a door leaf. An inlet and outlet is opened on the door frame. One movable end of the connecting hinge is fixedly installed on both sides of the inlet and outlet, and the other movable end of the connecting hinge is fixedly connected to the door leaf. The two door leaves are symmetrically arranged and closed in the inlet and outlet;
[0009] A moving mechanism and a driving mechanism are provided inside the opening and closing track. The moving mechanism is used to drive the active moving table to move left and right. The driving mechanism is used in cooperation with the moving mechanism. A linkage mechanism is provided on the active moving table, and the linkage mechanism is used in cooperation with the cleaning mechanism. The linkage mechanism is associated with the movement of the active moving table.
[0010] Preferably, the moving mechanism includes a control chute and a bearing rod. Control chutes are opened at the tops of both of the opening and closing tracks. A bearing rod is fixedly installed inside the control chute. The active moving table is slidably and penetratingly installed on the bearing rod, and the top surface of the active moving table extends out of the control chute.
[0011] Preferably, the driving mechanism includes an X-axis one-way lead screw and a control servo motor. The X-axis one-way lead screw is rotatably installed inside the control chute, and the bearing rod is arranged parallel to the X-axis one-way lead screw. Control servo motors are fixedly installed on the sides of both of the opening and closing tracks, and the output ends of the control servo motors are fixedly connected to the X-axis one-way lead screw. The active moving table is threadedly and penetratingly installed on the X-axis one-way lead screw. Each swing door main body is driven to move by a separate driving mechanism, so that the two swing door main bodies can be opened separately. That is, there are at least three usage modes of the swing door: the mode where the two swing doors are closed and in contact with each other, the mode where a single swing door is opened, and the mode where the two swing doors are away from each other. And the passing standards in each mode are different, and they are improved according to actual needs.
[0012] Preferably, the cleaning mechanism includes a driven rotating shaft and a cleaning brush. The driven rotating shaft is rotatably installed on the side of the active moving table, and the other end of the driven rotating shaft is fixedly connected to the cleaning brush. The cleaning brush is a soft brush, and the cleaning brush is in contact with the X-axis one-way lead screw and the bearing rod.
[0013] Preferably, a linkage chamber is opened inside the active moving table. The end of the driven rotating shaft away from the cleaning brush extends into the linkage chamber and is fixedly connected to a second bevel gear. The inner wall of the linkage chamber is rotatably installed with an active rotating shaft, and a first bevel gear is fixedly installed on the active rotating shaft. The first bevel gear is in meshing transmission with the second bevel gear.
[0014] Preferably, one end of the driving rotating shaft extends outside the driving moving platform and is fixedly connected with a circular gear. A straight bar is fixedly installed on the opening and closing track, and a through groove is formed at the top of the straight bar. An X-axis rack is fixedly installed in the through groove. The circular gear is meshed with the X-axis rack for transmission. During the movement of the driving moving platform, the circular gear will roll along the X-axis rack, that is, the driving rotating shaft drives the first bevel gear to rotate. Since the second bevel gear is meshed with the first bevel gear for transmission, when the swing door body moves, the driven rotating shaft can drive the cleaning brush to rotate, and the cleaning brush will move left and right at the same time, so that the cleaning brush can clean the X-axis single lead screw and the bearing rod, so as to improve the cleanliness of the structure, avoid jamming, enable the driving moving platform to move smoothly, and extend the maintenance time.
[0015] Preferably, a guiding sliding groove is formed at the top of the flat pushing track. A walking support mechanism is installed at the bottom of the swing door body, and the walking support mechanism is arranged in the guiding sliding groove. Docking plates are fixedly connected to both sides of the flat pushing track, and mounting holes are formed in the docking plates. The docking plates are inserted into the grooves on the side of the opening and closing track, and locking bolts are threadedly connected in the mounting holes, that is, the locking bolts are screwed on the opening and closing track. The length of the flat pushing track corresponds to the size of the swing door body and is formulated according to actual requirements. The flat pushing track is installed on the opening and closing track through the docking plates, the mounting holes and the locking bolts, and the disassembly and assembly are relatively convenient, so as to facilitate operations such as maintenance and lubrication.
[0016] Preferably, the walking support mechanism includes a U-shaped mounting seat, a wheel shaft and a guiding wheel. The U-shaped mounting seat is fixedly installed at the bottom of the swing door body, and a wheel shaft is rotatably installed in the U-shaped mounting seat. A guiding wheel is fixedly installed on the wheel shaft, and the guiding wheel is in rolling connection with the guiding sliding groove. When the swing door moves, the guiding wheel rolls in the guiding sliding groove. On the one hand, it guides and limits the swing door, and on the other hand, it supports the swing door, so that it can be applied to heavy swing doors and ensure the smooth movement of heavy swing doors.
[0017] In view of this, compared with the prior art, the beneficial effects of the present invention are:
[0018] (1). In this application, when the servo motor is controlled to be turned on, the X-axis single lead screw is driven to rotate, and the driving moving platform slides along the bearing rod, so that the swing door body moves along the flat pushing track until the two swing door bodies touch each other to block the passage and prevent vehicles from entering and leaving. By pushing the door leaf, the door leaf can be opened under the action of the connecting hinge, so that the entrance and exit are in an open state, and then pedestrians can enter and exit. In this mode, the staff can enter and exit, while vehicles need to be authorized to move the swing door body to enter and exit, which improves safety.
[0019] (2) In this application, each swing door body is driven to move by a separate driving mechanism, so that the two swing door bodies can be opened separately. That is, there are at least three usage modes for the swing door: the mode where the two swing doors are closed and in contact with each other, the mode where a single swing door is opened, and the mode where the two swing doors move away from each other. Moreover, the passing standards in each mode are different and need to be improved according to actual needs.
[0020] (3) In this application, when the swing door moves, the guide wheels roll in the guide chutes. On the one hand, they guide and limit the swing door, and on the other hand, they support the swing door, enabling it to be applied to heavy swing doors and ensuring the smooth movement of the heavy swing doors.
[0021] (4) In this application, during the movement of the active moving platform, the circular gear rolls along the X-axis rack. That is, the active rotating shaft drives the first bevel gear to rotate. Since the second bevel gear is in meshing transmission with the first bevel gear, when the swing door body moves, the driven rotating shaft can drive the cleaning brush to rotate, and the cleaning brush will also move left and right at the same time, enabling the cleaning brush to clean the X-axis single-direction screw rod and the bearing rod, so as to improve the cleanliness of the structure, avoid jamming, enable the active moving platform to move smoothly, and extend the maintenance time.
[0022] (5) In this application, the length of the flat push track corresponds to the size of the swing door body and is formulated according to actual needs. Moreover, the flat push track is installed together with the opening and closing track through the docking plate, installation holes, and locking bolts, and the disassembly and assembly are relatively convenient, thus facilitating operations such as maintenance and lubrication.
