[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-3The utility model provides an embodiment: a courtyard door with a buffering and deceleration function, comprising a support column 1, a rectangular array of pads 2 are slidably connected inside the support column 1, transmission rods 9 are rotatably connected to both sides of the inner wall of the pad 2, and a slider 11 is rotatably connected to one end of the transmission rod 9, a rectangular array of slide rails 8 are fixedly connected inside the support column 1, one side of the outer wall of the slider 11 is slidably connected to the outer wall of the slide rail 8, a rectangular array of fixed blocks 12 are fixedly connected inside the support column 1, one side of the outer wall of the slider 11 is fixedly connected to the slide bar 13, the slide bar 13 is slidably connected inside the fixed block 12, a compression spring 14 is sleeved on the outer wall of the slide bar 13, a left-right symmetrical spring damper 10 is rotatably connected to the inner wall of the pad 2, and the output end of the spring damper 10 is rotatably connected to the other side of the outer wall of the slider 11;

[0026] Specifically, the support column 1 can make the door panel 4 rotate, and the door panel 4 can be opened outward on the support column 1. A pad 2 is provided on the contact surface between the support column 1 and the door panel 4 when opening and closing. When the door panel 4 is opened and closed, the pad 2 can receive the impact when the door panel 4 is opened and closed. The pad 2 is made of rubber material, which can facilitate the protection of the door panel 4. The pad 2 floats inside the support column 1 through the force of the spring damper 10. When the pad 2 receives the impact, the force of the pad 2 can be received by the transmission rod 9, thereby transmitting it to the slider 11, so that the slider 11 slides on the slide rail 8, so that the force on the slider 11 is dispersed. In the process of force transmission by the transmission rod 9, the spring damper 10 can be used for buffering. When the slider 11 slides, the slide rod 13 can slide in the fixed block 12, so that the compression spring 14 can buffer its process. Then, the contact between the door panel 4 and the pad 2 can be buffered to a large extent, thereby protecting the door panel 4.

[0027] Reference Figure 4 and Figure 5 , a movable door assembly is rotatably connected to one side of the inner part of the support column 1, and the movable door assembly includes a door panel 4 and a door knocker 5, one side of the outer wall of the door panel 4 is rotatably connected to one side of the inner part of the support column 1, one side of the outer wall of the door knocker 5 is fixedly connected to one side of the outer wall of the door panel 4, a rectangular array of anti-theft spikes 3 are fixedly connected to the top of the door panel 4, and the bottom of the anti-theft spikes 3 is fixedly connected to the top of the support column 1, a hidden groove 17 is provided on one side of the outer wall of the door panel 4, a rotating block 7 is rotatably connected to one side of the inner part of the door panel 4, one side of the outer wall of the rotating block 7 is rotatably connected to the inside of the hidden groove 17, a card block 15 is fixedly connected to one side of the outer wall of the rotating block 7, and a card slot 16 is provided on one side of the outer wall of the door panel 4 for the card block 15 to be inserted into;

[0028] Specifically, the door panel 4 is designed with anti-theft spikes 3, and the support column 1 is also designed with anti-theft spikes 3, which can prevent thieves from climbing, thereby protecting the courtyard to a certain extent, and the anti-theft spikes 3 can be designed according to one's own needs to increase the aesthetics of the door panel 4, and a door knocker 5 is designed on the surface of the anti-theft spike 3 to facilitate the control of the opening and closing of the door panel 4, and this design conforms to the overall aesthetics of the courtyard. A rotating block 7 is rotated inside the door panel 4, and the rotating block 7 can be rotated to make the card block 15 snap into the card slot 16, so that the door panels 4 on both sides are fixed, and after the card block 15 is engaged with the card slot 16, the rotating block 7 will be hidden inside the hidden slot 17, thereby facilitating its overall aesthetics.

[0029] Reference Figure 1 and Figure 6 A lock box 6 is fixedly connected to one side of the outer wall of the door panel 4, a pressure block 19 is slidably connected inside the lock box 6, an electric push rod 18 is fixedly connected to one side of the inner part of the lock box 6, the pressure block 19 is fixedly connected to the output end of the electric push rod 18, and the electric push rod 18 is electrically connected to the inner part of the lock box 6;

[0030] Specifically, a lock box 6 is designed above the rotating block 7, and the electric push rod 18 can be intelligently controlled through the lock box 6. The mechanism can increase its safety and facilitate the protection of the courtyard by the door panel 4. When the electric push rod 18 is pushed, the pressure block 19 can be pushed out of the lock box 6 to press the rotating block 7, so that the rotating block 7 can be fixed in the hidden groove 17, and the door panel 4 can be fixed. Since the door panel 4 stands in the courtyard, it is necessary to ensure the corrosion resistance of its material to ensure its service life.

[0031] Working principle: When the door panel 4 is opened and closed, the pad plate 2 will receive the impact of the door panel 4, so that the pad plate 2 will retract into the support column 1 and be buffered by the spring damper 10, and then the force on the pad plate 2 will be transmitted to the slider 11 through the transmission rod 9, so that the slider 11 slides on the slide rail 8, so that the slide rod 13 on the slider 11 slides inside the fixed block 12, and the force is transmitted to the support column 1 through the fixed block 12 for dispersion, and is buffered by the compression spring 14, so as to protect the door panel 4. When the door panel 4 is closed, the rotating block 7 can be rotated to make the card block 15 card into the card slot 16, and then the rotating block 7 is hidden in the hidden slot 17, and then the lock box 6 controls the electric push rod 18 to run, so that the electric push rod 18 pushes out the pressure block 19, so that the pressure block 19 is pressed on the rotating block 7, so that the door panels 4 on both sides are fixed.
