Description

Technical Field

[0001] This invention relates to the field of swing door technology, specifically a high-speed swing door with a reinforced structure. Background Technology

[0002] High-speed swing doors are a special type of door that combines ventilation, dust prevention, light blocking, and decoration. They are widely used not only in industrial production workshops but also in commercial, medical, logistics centers, supermarkets, and other places.

[0003] To enhance the anti-theft capabilities of the production workshop and the impact resistance and lifespan of the swing high-speed doors, reinforcement components are installed inside the swing high-speed doors to increase the strength of the door panels. However, these reinforcement components increase the weight of the door panels, requiring a significant amount of physical effort to open or close them, thus increasing the time and energy required for operation. Summary of the Invention

[0004] The purpose of this invention is to provide a high-speed swing door with a reinforced structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-speed swing door with a reinforced structure, comprising a swing door, wherein the interior of the swing door is provided with a reinforcing component for strengthening the door panel itself.

[0006] The reinforcing components include mounting frames and reinforcing plates. Two mounting frames are slidably installed in the inner cavity of the swing door. Multiple sliders are symmetrically slidably installed on the upper and lower sides of the inner cavity of the mounting frames. Reinforcing plates are rotatably installed at the upper and lower ends of two adjacent sliders through a pivot. Two adjacent reinforcing plates are rotatably connected by a hinge.

[0007] Two first winding shafts are rotatably mounted on the side of the mounting frame away from the rotation center of the swing door. The outer walls of both first winding shafts are wound with first tension ropes. The free ends of the first tension ropes are fixedly connected to the outer walls of the two sliders closest to the first winding shafts. A second winding shaft is rotatably mounted on the side of the mounting frame away from the first winding shafts via a torsion spring. The outer walls of the second winding shafts are wound with second tension ropes. The free ends of the second tension ropes are fixedly connected to the outer walls of the two sliders closest to the first winding shafts.

[0008] Preferably, sliding grooves are provided on both the upper and lower sides of the inner cavity of the mounting frame, and multiple sliders are slidably installed in the inner cavity of the sliding grooves.

[0009] Preferably, each of the multiple sliders has a through hole on one of its adjacent sides, and the free end of the second tension rope passes through the multiple through holes and is fixedly connected to the outer wall of the two sliders closest to the first winding shaft.

[0010] Preferably, a bidirectional motor is fixedly installed on the side of the mounting frame near the first take-up shaft. The bidirectional motor is located between the two first take-up shafts, and both power output shafts of the bidirectional motor are fixedly connected to the adjacent ends of the two first take-up shafts.

[0011] Preferably, a sleeve is rotatably sleeved on the outer wall of the second winding shaft, the outer wall of the sleeve is fixedly connected to one side of the mounting frame, and a torsion spring connected to the inner wall of the sleeve is fixedly sleeved on the outer wall of the second winding shaft.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention describes a high-speed swing door with a reinforced structure. By using a reinforcing component, when the swing door is opened or closed, the reinforcing component moves towards the rotation center of the swing door, thereby changing the center of gravity of the swing door and effectively reducing the physical effort required to open or close the swing door, as well as the time and effort required to open or close the swing door.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Please see Figure 1-8 This embodiment provides a high-speed swing door with a reinforced structure, including a swing door 1. The swing door 1 is equipped with a reinforcing component inside to strengthen its own door panel. The swing door 1 can effectively connect or isolate the production workshop from the external environment, which is beneficial for the transfer and protection of items inside the production workshop.

[0029] The reinforcing components include mounting frames 2 and reinforcing plates 3. Two mounting frames 2 are slidably installed in the inner cavity of the swing door 1. Multiple sliders 8 are symmetrically slidably installed on the upper and lower sides of the inner cavity of the mounting frames 2. The upper and lower ends of two adjacent sliders 8 are rotatably installed with reinforcing plates 3 through a pivot. The side walls of the multiple reinforcing plates 3 are all attached to the inner wall of the swing door 1, thereby increasing the thickness of the door panel and its impact resistance, making it less prone to deformation or damage when impacted, and increasing the service life of the swing door 1.

[0030] Two adjacent reinforcing plates 3 are connected by a hinge. When the swing door 1 needs to be opened or closed, multiple reinforcing plates 3 are pushed towards the rotation center of the swing door 1. Under the action of the hinge, the multiple reinforcing plates 3 rotate relative to each other and are neatly stacked inside the mounting frame 2. At the same time, multiple sliders 8 move towards the rotation center of the swing door 1, thereby changing the center of gravity of the swing door 1 and moving it closer to the rotation center. This effectively reduces the physical effort required to open or close the swing door 1, and also reduces the time and effort required to open or close the swing door 1.

[0031] Two first winding shafts 4 are rotatably mounted on the side of the mounting frame 2 away from the rotation center of the swing door 1. The outer walls of the two first winding shafts 4 are wound with first tension ropes 12. The free ends of the first tension ropes 12 are fixedly connected to the outer walls of the two sliders 8 closest to the first winding shafts 4. When the swing door 1 is always in the closed state, the two first winding shafts 4 are rotated at the same time, causing the first tension ropes 12 to move towards the first winding shafts 4. At this time, the two sliders 8 at the rotation center of the swing door 1 move together with the first tension ropes 12, thereby causing the multiple reinforcing plates 3 to separate until they are reset.

[0032] A second winding shaft 6 is mounted on the side of the mounting frame 2 away from the first winding shaft 4 via a torsion spring. A second tension rope 9 is wound around the outer wall of the second winding shaft 6. The free end of the second tension rope 9 is fixedly connected to the outer wall of the two sliders 8 closest to the first winding shaft 4. When the swing door 1 needs to be opened or closed, the second winding shaft 6 is rotated, causing the second tension rope 9 to wind around the outer wall of the second winding shaft 6. At this time, the two sliders 8 furthest from the rotation center of the swing door 1 move towards the second winding shaft 6 simultaneously until the two sides of the multiple reinforcing plates 3 are tightly fitted together, which helps to change the center of gravity of the swing door 1.

[0033] Sliding grooves are provided on both the upper and lower sides of the inner cavity of the mounting frame 2. Multiple sliders 8 are slidably installed in the inner cavity of the sliding grooves. The sliding grooves can limit the sliding trajectory of the multiple sliders 8, prevent the multiple sliders 8 from deviating when sliding, and improve the stability of the sliding of the multiple sliders 8.

[0034] Multiple sliders 8 have through holes on their adjacent sides. The free end of the second tension rope 9 passes through multiple through holes and is fixedly connected to the outer wall of the two sliders 8 closest to the first winding shaft 4. This helps to limit the movement trajectory of the second tension rope 9 and improves the smoothness of its movement.

[0035] A bidirectional motor is fixedly installed on the side of the mounting frame 2 near the first take-up shaft 4. The bidirectional motor is located between the two first take-up shafts 4. The two power output shafts of the bidirectional motor are fixedly connected to the adjacent ends of the two first take-up shafts 4. When multiple reinforcing plates 3 need to be reset, the bidirectional motor is started, which allows the two first take-up shafts 4 to rotate synchronously. This helps the first tension rope 12 to be wound evenly and stably around the outer wall of the first take-up shaft 4.

[0036] The outer wall of the second take-up shaft 6 is rotatably sleeved with a sleeve 5. The outer wall of the sleeve 5 is fixedly connected to one side of the mounting frame 2. The outer wall of the second take-up shaft 6 is fixedly sleeved with a torsion spring connected to the inner wall of the sleeve 5. When multiple reinforcing plates 3 need to be stacked neatly, the bidirectional motor is turned off. At this time, the torsion spring quickly returns to its original position, allowing the second take-up shaft 6 to rotate, so that the second tension rope 9 is neatly wound around the outer wall of the second take-up shaft 6, which is conducive to stacking the reinforcing plates 3.

[0037] The thickness of the mounting frame 2 is no greater than the thickness of the reinforcing plate 3. The thickness of the mounting frame 2 and the thickness of the reinforcing plate 3 are the same, which allows the side walls of the mounting frame 2 and the reinforcing plate 3 to fit against the inner wall of the door panel at the same time, further improving the strength of the door panel.

[0038] Example 2

[0039] Please see Figure 1-8 Further improvements made based on Example 1:

[0040] Multiple guide rails 7 are fixedly installed on both the upper and lower sides of the inner cavity of the swing door 1. The multiple guide rails 7 are symmetrically distributed on the upper and lower sides of the mounting frame 2. Multiple transmission blocks 14 are fixedly installed on both the upper and lower sides of the mounting frame 2. The end of the transmission block 14 away from the mounting frame 2 extends into the inner cavity of the guide rail 7. The multiple guide rails 7 can limit the sliding trajectory of the multiple transmission blocks 14, thereby improving the sliding stability of the mounting frame 2.

[0041] A top pressure spring 13 connected to the transmission block 14 is fixedly installed in the inner cavity of the guide slide rail 7. Two top pressure springs 13 are fixedly installed inside the multiple guide slide rails 7. The two top pressure springs 13 can apply a pushing force to the two transmission blocks 14 located inside the same guide slide rail 7 in a direction that always moves away from each other, which is beneficial for the mounting frame 2 and the side wall of the reinforcing plate 3 to fit tightly against the inner wall of the door panel.

[0042] Two mounting plates 11 are fixedly installed in the inner cavity of the swing door 1. The two mounting plates 11 are located between two mounting frames 2, and electromagnets 10 are fixedly installed on both sides of the two mounting plates 11 near the mounting frames 2. When the swing door 1 needs to be closed or opened, the electromagnets 10 are energized. At this time, the two mounting frames 2 move towards the mounting plates 11 at the same time until the two mounting frames 2 are in contact with the sides of the mounting plates 11. This is beneficial for the mounting frames 2 and the reinforcing plates 3 to be separated from the inner wall of the door panel at the same time, preventing the reinforcing plates 3 from contacting the inner wall of the door panel when stacked or reset, and improving the smoothness of the stacking and reset of the reinforcing plates 3.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
