Description

Technical Field

[0001] The utility model relates to the technical field of door leaves, in particular to a double-door device. Background Art

[0002] In the design of existing double-door devices, when one door panel closes before the other, if there is a stop piece or other obstacles on the side of this door panel, it may cause the other door panel to be blocked and unable to close smoothly, affecting the convenience of use and the sealing performance of the door. Content of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a double-door device, which can enable two door panels to close in sequence or freely and smoothly under specific conditions through a simple stop component.

[0004] The double-door device according to the first aspect embodiment of the utility model includes a door frame and a stop component. The door frame is hinged with a first door panel and a second door panel. Both the first door panel and the second door panel can rotate towards the middle of the door frame to open and close. The stop component includes a mounting seat and a support arm. The mounting seat is fixed to the top of the door frame and is located on one side of the middle of the door frame deviating from the second door panel. The support arm is rotatably connected to the mounting seat. The support arm extends towards the second door panel to form a limiting rod. The limiting rod is arranged obliquely downward to abut against the second door panel to limit the closing of the second door panel. The support arm is provided with a driving part. When the second door panel rotates towards the middle of the door frame to close, it can abut against and drive the driving part to rotate. The driving part rotates to drive the support arm to rotate, and the limiting rod is separated from the second door panel, and the second door panel can rotate to close.

[0005] According to the double-door device of the embodiment of the utility model, at least the following beneficial effects are achieved: when the user pushes or pulls the first door panel to rotate toward the middle of the door frame, the first door panel will be closed freely and smoothly, because at this time the limit rod of the stop assembly does not hinder the moving path of the first door panel. Then, the user tries to close the second door panel. In the early stage when the second door panel starts to rotate toward the middle of the door frame, if the first door panel is already closed and there is no obstruction, the second door panel will continue to rotate directly until it is closed. In this process, if the second door panel attempts to close before the first door panel, and the first door panel is not completely closed at this time, the edge of the second door panel will first contact the limit rod of the stop assembly. The limit rod will generate resistance to the second door panel due to its downward inclination, preventing it from continuing to close. This resistance will remind the user that the first door panel needs to be closed first. When the user realizes this and closes the first door panel first, the limit rod of the stop assembly no longer blocks the path of the second door panel. In other embodiments, the user needs to try to close the second door panel first, but because the first door panel has not been closed, the edge of the second door panel will contact the limit rod of the stop assembly. The limit rod prevents the second door panel from closing further and emits an obvious resistance feeling, prompting the user to change the door closing sequence. After the first door panel is completely closed, the limit rod of the stop assembly no longer blocks the path of the second door panel through the rotation of the support arm.

[0006] According to some embodiments of the present invention, a guiding slope is provided on the top of the first door panel, and the guiding slope is inclined upward from one side close to the door frame toward the other side.

[0007] According to some embodiments of the present utility model, the driving part includes a driving wheel and a driving plate, the driving plate is connected to one end of the support arm, and the driving wheel is connected to the driving plate.

[0008] According to some embodiments of the utility model, the mounting seat is flush with the door frame, and two sockets are symmetrically arranged along the length direction. The sockets are rotatably provided with a rotating shaft, the rotating shaft is connected to the support arm, and the support arm rotates around the axis of the rotating shaft.

[0009] According to some embodiments of the utility model, the driving plate is located on a side of the socket close to the support arm, and the driving plate is provided with a penetrating adjustment slot, the adjustment slot is inclined, and an adjustment screw is passed through the adjustment slot. The adjustment screw is rotated to extend into the adjustment slot and can abut the upper or lower part of the mounting seat to adjust the inclination angle of the support arm.

[0010] According to some embodiments of the utility model, a yield slope is provided on the lower side of the driving plate, the yield slope is inclined from bottom to top, and the adjustment slot is located at the lowest point of the yield slope.

[0011] According to some embodiments of the present utility model, a buffer roller is rotatably provided at the end of the limiting rod, and the buffer roller is made of silica gel.

[0023] Refer to Figure 1 , Figure 2 and Figure 3, the present utility model provides a double - door opening device, which includes a door frame 100 and a stop component 200. The door frame 100 is hinged with a first door panel 110 and a second door panel 120. Both the first door panel 110 and the second door panel 120 can rotate towards the middle of the door frame 100 to achieve opening and closing. The stop component 200 includes a mounting seat 210 and a support arm 220. The mounting seat 210 is fixed to the top of the door frame 100 and is located on one side of the middle of the door frame 100 deviating from the second door panel 120. The support arm 220 is rotatably connected to the mounting seat 210. A limiting rod 221 extends towards the second door panel 120 on the support arm 220. The limiting rod 221 is arranged obliquely downward to abut against the second door panel 120 to limit the closing of the second door panel 120. The support arm 220 is provided with a driving part 230. When the second door panel 120 rotates towards the middle of the door frame 100 to close, it can abut against and drive the driving part 230 to rotate. The driving part 230 rotates to drive the support arm 220 to rotate, and the limiting rod 221 is separated from the second door panel 120, and the second door panel 120 can rotate to close.

[0024] Specifically, when the user pushes or pulls the first door panel 110 to rotate towards the middle of the door frame 100, the first door panel 110 will close freely and smoothly because the limiting rod 221 of the stop component 200 does not obstruct the moving path of the first door panel 110 at this time. Then, the user tries to close the second door panel 120. In the initial stage when the second door panel 120 starts to rotate towards the middle of the door frame 100, if the first door panel 110 has been closed and there is no obstruction, the second door panel 120 will directly continue to rotate until it is closed. During this process, if the second door panel 120 attempts to close before the first door panel 110 and the first door panel 110 has not been fully closed at this time, then the edge of the second door panel 120 will first contact the limiting rod 221 of the stop component 200. Due to its oblique downward setting, the limiting rod 221 will generate a resistance to the second door panel 120, preventing it from continuing to close. This resistance will remind the user that the first door panel 110 needs to be closed first. When the user realizes this and closes the first door panel 110 first, the limiting rod 221 of the stop component 200 no longer blocks the path of the second door panel 120. In some other embodiments, the user needs to try to close the second door panel 120 first, but due to the first door panel 110 not being closed, the edge of the second door panel 120 will contact the limiting rod 221 of the stop component 200. The limiting rod 221 prevents the second door panel 120 from continuing to close and gives an obvious sense of resistance, prompting the user to change the order of closing the doors. After the first door panel 110 is completely closed, the limiting rod 221 of the stop component 200 no longer blocks the path of the second door panel 120 through the rotation of the support arm 220.

[0025] It should be noted that through the design of the blocking component 200, the present utility model can ensure that before the first door panel 110 is completely closed, the premature closing of the second door panel 120 is blocked, avoiding the problem of inability to close caused by mutual blocking between the door panels. And since the door panels can be closed in sequence or smoothly and freely, the gaps caused by improper closing are avoided, thereby improving the safety of the door. Users do not need to pay special attention to the closing sequence of the door panels, and only need to operate according to daily habits, ensuring the smoothness of use. On the other hand, the blocking component 200 has a compact structure, is easy to install, and requires low material costs, making it suitable for large-scale popularization and application.

[0026] Referring to Figure 1 , in some embodiments, the top of the first door panel 110 has a guiding inclined surface that starts from the side close to the door frame 100 and slopes upward and outward. When the first door panel 110 is closed, the driving part 230 first contacts the lowest point of the guiding inclined surface. As the first door panel 110 rotates, the driving part 230 gradually rises with the increase in the height of the guiding inclined surface, thereby driving the support arm 220 to rotate and the limiting rod 221 to rotate and rise, thus releasing the restriction on the second door panel 120. As the first door panel 110 is gradually closed, the smooth rise of the driving part 230 on the guiding inclined surface ensures the smooth rotation of the support arm 220 and the limiting rod 221. This smooth transition reduces the impact and wear between mechanical components, extends the service life, and improves the stability and reliability of the entire double-door device system. And without additional control devices or operations, only through the interaction of physical structures, the intelligent and automatic control of the closing sequence of the double-door device is achieved. This design simplifies the user operation and improves the convenience of use

[0027] Referring to Figure 2 , further, the driving part 230 is composed of a driving wheel 232 and a driving plate 231. The driving plate 231 is firmly connected to one end of the support arm 220, and the driving wheel 232 is installed on the driving plate 231. When the second door panel 120 attempts to close and contacts the driving wheel 232, it will push the driving wheel 232 to rotate, and then drive the support arm 220 to rotate around its rotating shaft 240 through the driving plate 231, making the driving process smoother and more reliable, while reducing mechanical wear and noise.

[0028] Referring to Figure 2 , and Figure 3 , specifically, the mounting seat 210 is flush with the door frame 100, and two sockets 211 are symmetrically arranged along its length direction. A rotating shaft 240 is rotatably installed in each socket 211, and the rotating shaft 240 is connected to the support arm 220, enabling the support arm 220 to freely rotate around the axis of the rotating shaft 240, which not only enhances the structural stability but also makes the rotation of the support arm 220 more flexible and precise.

[0029] Further, an adjustment slot is provided on one side of the drive plate 231 close to the support arm 220, and the adjustment slot is inclined. By means of an adjustment screw 233 passing through the adjustment slot, the inclination angle of the support arm 220 can be conveniently adjusted. In a specific embodiment, when the adjustment screw 233 rotates and extends into different positions of the adjustment slot, it abuts against the upper or lower part of the mounting seat 210, and the mounting seat 210 is correspondingly provided with a matching boss or clamping platform for accommodating the force of the adjustment screw 233, so as to change the inclination state of the support arm 220, making the stopper assembly 200 more adaptable and adjustable according to different usage requirements. Preferably, adjustment screws 233 are provided on both the upper and lower sides of the drive plate 231, which are respectively inclined from top to bottom and from bottom to top, and the user can adjust each adjustment screw 233 as needed to quickly adjust the inclination angle of the support arm 220. The inclination angle of the support arm 220 is preferably perpendicular to the second door panel 120.

[0030] Referring to Figure 2 , specifically, a relief inclined surface 234 is provided on the lower side of the drive plate 231, and the inclined surface is inclined from bottom to top, and the adjustment slot is located at the lowest point of the relief inclined surface 234. When adjusting the inclination angle of the support arm 220, the adjustment screw 233 can more easily enter or exit the adjustment slot, facilitating user operation and providing more space for the rotation of the support arm 220.

[0031] Referring to Figure 2 and Figure 3 , it should be noted that a buffer roller 222 is rotatably provided at the end of the limiting rod 221, and the buffer roller 222 is preferably made of a silicone product. When the second door panel 120 contacts the limiting rod 221, the buffer roller 222 can play a role in buffering and shock absorption, reducing the direct collision and noise between the door panel and the limiting rod 221. At the same time, the buffer roller 222 made of a silicone product also has advantages such as wear resistance and corrosion resistance, and can extend the service life.

[0032] Referring to Figure 2 and Figure 3 , specifically, two mounting holes 212 are provided on the mounting seat 210, and these mounting holes 212 are used for passing through fasteners (such as bolts or screws) fixed to the door frame 100. Ensure that the mounting seat 210 is firmly fixed on the door frame 100 and is not easily loosened or detached. At the same time, it also facilitates the installation and disassembly process.

[0033] The embodiments of the present invention have been described in detail above with reference to the drawings, but the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art.
