Description

Technical Field

[0001] The utility model relates to the technical field of industrial doors, in particular to a built-in driven industrial door roller shutter. Background Art

[0002] In the field of industrial automation and logistics, industrial door rollers are a widely used device, mainly used to control the opening and closing of industrial doors or warehouse doors. With the improvement of industrial automation level, higher requirements are also placed on the performance, safety and ease of use of industrial door rollers.

[0003] Traditional industrial door roller shutters have some shortcomings in design and structure. First of all, Figure 1 As mentioned above, the motor is usually installed outside the reel, which makes the whole device larger in size, occupies more space, and is not conducive to installation and use. Secondly, the traditional connection between the reel and the motor mostly adopts direct transmission, which may lead to low transmission efficiency and easy to produce noise and wear due to friction. This requires a torsion spring balance system to ensure that the door body runs smoothly during opening and closing, and by bearing part of the weight of the door body, the burden of the motor when driving the door body can be greatly reduced. However, since the bidirectional bending surface of the torsion spring is not easy to control, the initial tension is difficult to adjust and master. Once it loses control, it is difficult to recover, which may lead to instability or damage to the door. In addition, the balance and stability of the torsion spring are relatively poor, requiring more maintenance and adjustment. This may cause the door to be unstable or deflected during operation, affecting the use effect. For this reason, we propose a built-in drive industrial door roller shutter. Utility Model Content

[0007] Steel wire reels are also sleeved on both ends of the beam tube.

[0008] In some embodiments, a rotating shaft is rotatably mounted on the angle side plate using a bearing seat, the beam tube is fixed on the rotating shaft, and an anti-skid brake used in conjunction with the rotating shaft is also provided on the angle side plate.

[0009] In some embodiments, the beam tube is a polygonal hollow sleeve structure, and polygonal inner tubes are provided at the end of the rotating shaft and the driving end of the tubular motor. The polygonal inner tubes are all located in the beam tube, and fixing parts are provided between the beam tube and the polygonal inner tubes to fix the beam tube and the polygonal inner tube.

[0010] In some embodiments, the fixing member includes a plurality of bolts respectively penetrating the beam tube, and screw holes matching the bolts are opened on the polygonal inner tube, so that the beam tube and the polygonal inner tube can be fixed with bolts from the outside of the beam tube.

[0011] In some embodiments, a polygonal tail plug having a diameter greater than the diameter of both ends of the beam tube is provided at a section of the tubular motor located at the end of the beam tube and at a section of the rotating shaft located at the end of the beam tube, and when the beam tube contacts the polygonal tail plug, the screw holes on the polygonal inner tube are exactly opposite to the bolts.

[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] See also Figure 1-5 The utility model provides a technical solution: a built-in driven industrial door roller shutter, which is mainly composed of two corner side plates 1, a beam tube 2, a tubular motor 3, a wire reel 4 and key connecting parts.

[0026] A rotatable shaft 5 is installed on the corner side plate 1 through a bearing seat, and the beam tube 2 is firmly fixed on the shaft 5, thereby realizing flexible rotation of the beam tube 2. In addition, the corner side plate 1 is also equipped with an anti-skid brake 6 that works in conjunction with the shaft 5 to ensure that the movement of the roller shutter can be stopped quickly and stably when needed.

[0027] The beam tube 2 adopts a multilateral hollow sleeve structure, which not only increases the structural strength but also optimizes the internal space utilization. At the end of the rotating shaft 5 and the driving end of the tubular motor 3, there are designed multilateral inner tubes 7, which match the inside of the beam tube 2 and are firmly connected through a well-designed fixing member 8. The fixing member 8 includes a bolt 9 passing through the beam tube 2 and a corresponding screw hole 10 on the polygonal inner tube 7. This design makes installation and disassembly more convenient and ensures the stability of the connection.

[0028] In addition, this design makes it possible for the main force to act on the polygonal inner tube 7 when driving the beam tube 2 to rotate, and the positioning member 8 is mainly used to limit the separation of the beam tube 2 from the polygonal inner tube 7. However, during the rotation of the beam tube 2, it does not cause inconvenience to the tubular motor 3 in the turning of the beam tube 2, thereby determining that the main force comes from it.

[0029] In order to further improve the stability of the connection and the convenience of operation, multilateral tail plugs 11 are provided at the ends of the tubular motor 3 and the rotating shaft 5. The diameter of these tail plugs is larger than the port of the beam tube 2. When the beam tube 2 contacts the tail plugs, the screw holes 10 on the polygonal inner tube 7 can be accurately aligned with the bolts 9, which greatly simplifies the installation and adjustment process.

[0030] In addition, the pipe ends of the beam tube 2 are chamfered, which not only improves the aesthetics, but also reduces the scratches and wear that may be caused during assembly and disassembly, and facilitates the installation and insertion of the multilateral inner tube 7, thereby extending the service life of the equipment.

[0031] In addition, the beam tube 2 side is an integer polygonal design including at least five sides.

[0032] It should be noted that, in general, this optimized built-in driven industrial door roller shutter design, while maintaining a compact size, significantly improves the stability, durability and ease of use of the equipment through carefully designed connection components and fixing mechanisms, providing a more efficient and reliable solution for the application of industrial door roller shutters.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
