Description

Technical Field

[0001] This utility model relates to the field of industrial door technology, and in particular to an industrial door torsion spring assist structure. Background Technology

[0002] Industrial doors are widely used in modern industrial production and warehousing environments, and are typically driven by motors or other drive sources. While current industrial door drive systems can meet basic opening and closing requirements, they also have some significant shortcomings.

[0003] Because the drive source needs to provide all the power directly, it is subjected to significant stress. Prolonged high-load operation not only increases the energy consumption of the drive source but also subjects related mechanical components to excessive stress, making them prone to wear and fatigue, thus reducing the equipment's lifespan.

[0004] Furthermore, increased load on the drive source can also affect the operational stability and reliability of industrial doors. Frequent repairs and replacements not only increase maintenance costs but also impact the continuity and efficiency of industrial production.

[0005] To address the above issues, we have introduced an industrial door torsion spring assist structure. Utility Model Content

[0006] This utility model discloses an industrial door torsion spring assist structure, which aims to solve the technical problems in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An industrial door torsion spring assist structure includes two door frames arranged symmetrically. A storage groove plate is fixedly connected between the tops of the two door frames. A connecting plate is fixedly connected between the two door frames and on one side of the storage groove plate. A mounting bracket is fixedly connected inside each door frame. Connecting rods are equidistantly movably connected inside each door frame. A smooth rod is rotatably connected between the two door frames. A fixing block is fixedly connected to the inner side of the connecting plate. A first connecting gear is fixedly connected to the outer side of the smooth rod. A second connecting gear is rotatably connected to one side of the fixing block. A sliding block is slidably connected to the outer side of the smooth rod. A contact plate is connected to the side of the sliding block that is close to the fixing block. The contact plate is rotatably connected to the fixing block and fixedly connected to the sliding block. The contact plate is connected to the second connecting gear. A first connecting chain is sleeved between the outer sides of the first and second connecting gears. A torsion spring is fixedly connected between the two contact plates.

[0009] When the guide rod rotates, it drives the first connecting gear to rotate. The first connecting gear drives the second connecting gear to rotate via the first connecting chain. In turn, the second connecting gear drives one of the contact discs to rotate. When the contact disc rotates, it drives the torsion spring to rotate, which shortens the stroke of the torsion spring. This allows the sliding block to move, thus using the torsion spring to assist in the return of the guide rod to its original position, making the operation of the device smoother.

[0010] In a preferred embodiment, two third connecting gears are symmetrically fixedly connected to the outer side of the light rod, and a mating gear is provided inside the door frame. A second connecting chain is sleeved between the third connecting gear and the mating gear, and the second connecting chain is connected to the corresponding connecting rod.

[0011] The smooth rod drives the third connecting gear to rotate, which in turn drives the connecting rod to rise through the transmission of the second connecting chain and the mating gear.

[0012] In a preferred embodiment, each of the mounting brackets is rotatably connected to a fourth connecting gear, which is connected to a guide rod. A fifth connecting gear is rotatably connected to the mounting bracket and located on one side of the fourth connecting gear, with the fourth connecting gear and the fifth connecting gear meshing with each other.

[0013] The guide rod drives the fourth connecting gear to rotate, and the fourth connecting gear, through meshing, drives the fifth connecting gear to rotate.

[0014] In a preferred embodiment, a sixth connecting gear is rotatably connected to the outer side of each mounting bracket, and each sixth connecting gear is connected to a corresponding fifth connecting gear.

[0015] The fifth connecting gear drives the sixth connecting gear to rotate, thus enabling the sixth connecting gear to rotate.

[0016] In a preferred embodiment, a drive motor is fixedly connected inside the connecting plate, a seventh connecting gear is fixedly connected to the output end of the drive motor, an eighth connecting gear is fixedly connected to the outside of the optical rod, and a third connecting chain is sleeved between the seventh connecting gear and the eighth connecting gear.

[0017] The drive motor can rotate the seventh connecting gear, which in turn drives the eighth connecting gear through the third connecting chain, thereby causing the guide rod to rotate.

[0018] In a preferred embodiment, a door panel is connected between the two connecting rods.

[0019] The lifting and lowering of the connecting rod can then drive the door panel to rise and fall.

[0020] The torsion spring assist structure for industrial doors provided by this utility model has the following advantages:

[0021] The motor drives the seventh gear to rotate, which in turn drives the third chain to rotate the eighth gear, thus causing the guide rod to rotate. As the guide rod rotates, it drives the first gear, which in turn drives the first chain to rotate the second gear, causing the contact plate and torsion spring to rotate. This shortens the torsion spring's stroke and pushes the sliding block to move. In this way, the torsion spring assists in the guide rod's reset. This design not only makes the device operate more smoothly but also improves the coordination efficiency of various components, enhancing overall performance and stability.
