Description

Technical Field

[0001] The utility model relates to the technical field of electric retractable doors, and specifically relates to an electric retractable door. Background Technique

[0002] The electric retractable door is also known as the "electric door" or "electric folding door". The electric retractable door mainly consists of a door body, a driver, and a control system. The door body of the retractable door is made of high-quality aluminum alloy and ordinary square tube materials, and is hinged using the parallelogram principle, with flexible expansion and contraction and a large stroke. The electric retractable door is widely applicable to various industrial and mining factories, workshops, warehouses, machine rooms, garages and other places as a movable fence, greatly expanding the application range of the electric retractable door.

[0003] The existing patent CN221371952U discloses a trackless electric retractable door, including a retraction box. An retractable door is arranged in the inner cavity of the retraction box. An anti-pinch component is arranged at one end of the retractable door away from the retraction box. A fixed box is arranged at the front end of the retraction box. A slideway is opened at the top of the fixed box. One end of the slideway extends to the left side of the fixed box. An installation box is arranged at the front end of the fixed box. A driving component is arranged in the inner cavity of the installation box. One end of the driving component extends into the inner cavity of the fixed box and is fixedly installed with a car blocking rod. This trackless electric retractable door solves the problem that the electric retractable door does not have the function of a car blocking rod and needs to be used in combination with a separate car blocking rod, with a single function. Through the setting of the anti-pinch component, when the device comes into contact with the human body, the power can be automatically cut off and the sliding can be stopped, avoiding the situation where pedestrians are hit by the retractable door, and improving the safety of the device during use.

[0004] Based on the retrieval of the above patent and the combination with the electric retractable doors in the existing technology, it is found that when the above electric retractable door is in use, although the number of times of opening and closing the electric retractable door can be reduced through the car blocking rod, when the electric retractable door is opened, there is a lack of a cleaning structure. If there is garbage on the ground, it will affect the normal opening of the electric retractable door. Moreover, when the car blocking rod is closed, the vertical rod comes into hard contact with the ground and wears relatively quickly, resulting in a reduction in practicality.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present utility model provides a technical solution: an electric retractable door, including a contraction box 1 and a vehicle blocking rod 11. An electric retractable door main body 12 is installed in the contraction box 1. A cleaning component is provided on the electric retractable door main body 12. A supporting component is provided at the bottom of the vehicle blocking rod 11. The cleaning component includes U-shaped frames 21 respectively arranged on both sides of the electric retractable door main body 12, a rotating shaft 22 connected to the U-shaped frames 21, a first motor 23 fixedly connected to one end of the rotating shaft 22, a rotating roller 24 fixedly connected to the outer side of the rotating shaft 22, a brush 25 fixedly connected to the outer side of the rotating roller 24, and an adjusting component for adjusting the height of the rotating roller 24. The rotating shaft 22 is rotatably connected to the U-shaped frames 21. The first motor 23 can drive the rotating shaft 22 to rotate. The rotating shaft 22 can drive the rotating roller 24 to rotate. The rotating roller 24 can make the brush 25 rotate, and then the impurities on the ground can be swept to the front and rear sides of the electric retractable door main body 12, and the garbage impurities can be cleaned up, which is convenient for the opening of the electric retractable door main body 12 and prevents the impurities from affecting its normal opening. The adjusting component includes cross plates 41 respectively fixedly connected to both sides of the electric retractable door main body 12, a second motor 42 fixedly connected to the top of the cross plates 41, a screw rod 43 fixedly connected to the bottom of the second motor 42, and a moving frame 44 connected to the outer side of the screw rod 43. The bottom of the moving frame 44 is fixedly connected to the top of the U-shaped frames 21. The screw rod 43 is screwed to the moving frame 44. The screw rod 43 is rotatably connected to the cross plates 41. When the second motor 42 starts, the screw rod 43 can be driven to rotate, and then the vertical movement of the moving frame 44 can be controlled. Further, the U-shaped frames can be driven to move vertically, and then it is convenient to drive the brush 25 to contact the ground, which is convenient for cleaning the impurities on the ground. Anti-rotation grooves 61 are respectively formed on both sides of the electric retractable door main body 12. An anti-rotation block 62 is slidably connected in the anti-rotation grooves 61. A fixing block 63 is fixedly connected between the anti-rotation block 62 and the moving frame 44. The moving frame 44 can drive the fixing block 63 and the anti-rotation block 62 to move vertically, and then the rotation of the moving frame 44 can be stopped, preventing the moving frame 44 from rotating synchronously with the screw rod 43 and ensuring the vertical stable movement of the moving frame 44. A limiting plate 81 is provided at the bottom of the screw rod 43. The limiting plate 81 is fixedly connected to the screw rod 43. The limiting plate 81 can limit the moving frame 44 to prevent it from vertically moving away from the screw rod 43.

The spring 35 can be used to protect the fixed seat 34 and improve its service life. The fixed seat 34, the moving rod 33, and the support rod 31 can support the parking rod 11 to prevent it from tilting. Protection grooves 51 are respectively opened on both sides in the moving groove 32, and protection plates 52 are respectively fixedly connected to both sides of the moving rod 33. The protection plates 52 are slidably connected to the protection grooves 51. The protection plates 52 can move synchronously with the moving rod 33, which can prevent the moving rod 33 from rotating, and further prevent the spring 35 from rotating and being damaged. A support block 71 is fixedly connected to the front of the retraction box 1. A notch 72 is opened at the top of the support block 71. A drive shaft 73 is disposed in the notch 72. One end of the drive shaft 73 is fixedly connected to a third motor 74. The drive shaft 73 is rotatably connected to the support block 71.

The first motor 23 can drive the rotating shaft 22 to rotate. The rotating shaft 22 can drive the rotating roller 24 to rotate. The rotation of the rotating roller 24 can drive the brush hair 25 to rotate, and then can clean the impurities on both the front and back sides of the electric retractable door main body 12. When the electric retractable door main body 12 is opened, the brush hair 25 can clean the impurities on its moving path to ensure its stable opening. Starting the third motor 74 can drive the drive shaft 73 to rotate. The rotation of the drive shaft 73 can drive the parking rod 11 to rotate and close. The rotation of the parking rod 11 can drive the fixed seat 34 to rotate. The rotation of the fixed seat 34 can contact the ground. The movement of the fixed seat 34 can drive the moving rod 33 to move. The movement of the moving rod 33 can squeeze the spring 35 to deform it. The spring 35 can play a buffering role and can improve the service life of the fixed seat 34.
