Description

Technical Field

[0001] The utility model relates to the technical field of industrial lifting doors, in particular to an industrial lifting door for protection and impact resistance. Background Art

[0002] Industrial lifting doors are composed of a series of door panels that rise along a track. They have the advantages of flexible installation, easy operation, and good anti-theft properties. Therefore, they are widely used in stores, garages, warehouses and workshops. A torsion spring system or a counterweight system ensures the door body's balance. Different track systems and lifting methods make industrial lifting door panels adaptable to different buildings. The door panels are composed of two layers of galvanized steel plates with a spray-coated surface for high oxidation resistance. The space between the two steel plates is filled with high-density expanded polyurethane foam, which has good thermal and sound insulation properties and strong mechanical resistance.

[0003] However, in order to enable the door panels to move inside the track, two adjacent door panels are mostly connected by hinges, which results in a weak connection strength between the two door panels. When subjected to internal or external collisions or impacts, the hinges are easily damaged, making it impossible for the door panels to move smoothly inside the track, affecting the normal use of the industrial lifting door.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0021] See also Figure 1-4 The present invention provides an industrial lifting door for protecting against impact, including a door panel 1, a base 2 is arranged between the two door panels 1, and a reinforcing plate 3 is integrally formed on the surface of the base 2. The reinforcing plate 3 is attached to the surface of the door panel 1, and the connection between the base 2 and the reinforcing plate 3 is transitioned through a first inclined surface 4. The surface of the door panel 1 is provided with a second inclined surface 5, and the second inclined surface 5 is in contact with the surface of the first inclined surface 4. A first connecting seat 6 is detachably installed on the base 2, and a second connecting seat 7 is detachably installed on the surface of the door panel 1. The first connecting seat 6 and the second connecting seat 7 are hinged, and a supporting mechanism is provided between the two first connecting seats 6 to contact the joint between the door panel 1 and the base 2.

[0022] See also Figure 1 、 2 and 4. Since the base 2 protrudes from the surface of the door panel 1, when the door panel 1 is impacted, the base 2 is impacted first. When the base 2 is subjected to force, it will drive the reinforcing plate 3 to contact the surface of the door panel 1, thereby protecting the hinge of the first connecting seat 6 and the second connecting seat 7 through the reinforcing plate 3. At the same time, the supporting mechanism is subjected to force and can absorb part of the impact force.

[0023] It should be noted that, due to the provision of the first inclined surface 4 , the second inclined surface 5 and the reinforcing plate 3 , the contact area between the base 2 and the door panel 1 is greatly increased, thereby improving the sealing between the base 2 and the door panel 1 .

[0024] The supporting mechanism includes a supporting plate 8, a supporting rod 9, a cross rod 10, a connecting rod 11 and a tilting rod 12. The supporting rod 9 is vertically fixed to the surface of the cross rod 10, the supporting plate 8 is fixed to the end face of the support rod 9, one side of the supporting plate 8 is in contact with the joint between the door panel 1 and the base 2, the tilting rod 12 is fixed to one end of the cross rod 10, the connecting rod 11 is fixed to one end of the tilting rod 12 and is movably arranged on the surface of the first connecting seat 6 through an elastic structure, the elastic structure includes a spring 13, a guide rod 14 and a limiter, the guide rod 14 is vertically fixed to the surface of the first connecting seat 6, the limiter is fixed to one end of the guide rod 14, the connecting rod 11 is slidably arranged on the surface of the guide rod 14, the spring 13 is fixed between the limiter and the connecting rod 11, the spring 13 is sleeved on the surface of the guide rod 14, and the top and bottom of the support plate 8 are both set to circular surfaces.

[0025] See also Figure 2 and 3 The base 2 can be supported by the reinforcing plate 3 when it is impacted. If the door panel 1 is impacted, the door panel 1 will transfer part of the impact to the cross bar 10 through the support plate 8 and the support rod 9, so that the cross bar 10, the tilting rod 12 and the connecting rod 11 can share the impact force together, dispersing the impact force exerted on the first connecting seat 6 and the second connecting seat 7, so as to protect the hinge of the first connecting seat 6 and the second connecting seat 7.

[0026] It should be noted that when the base 2 and the door panel 1 run inside the track, rotation will occur between the first connecting seat 6 and the second connecting seat 7. The setting of the reinforcement plate 3 will not hinder the rotation of the door panel 1, and the door panel 1 will push the support plate 8 through the circular surface to move away from the base 2 when rotating. At this time, the spring 13 will be compressed, and the kinetic energy of the spring 13 can facilitate the rapid reset of the base 2 and the door panel 1.

[0027] A first countersunk hole 15 is provided on the surface of the first connecting seat 6, and the first connecting seat 6 is installed on the surface of the base 2 through the first countersunk hole 15 and the first bolt 16. A second countersunk hole 17 is provided on the surface of the second connecting seat 7, and the second connecting seat 7 is installed on the surface of the door panel 1 through the second countersunk hole 17 and the second bolt 18.

[0028] See also Figure 2 The connection between the first connecting seat 6 and the base 2 is achieved through the first countersunk hole 15 and the first bolt 16, and the connection between the second connecting seat 7 and the door panel 1 is achieved through the second countersunk hole 17 and the second bolt 18, so that the number of supporting mechanisms and the installation positions of the first connecting seat 6 and the second connecting seat 7 can be arranged according to the actual size of the door panel 1, so as to adapt to different usage scenarios.

[0029] The limiting member is configured as a circular limiting plate 19 . The circular limiting plate 19 is fixed to one end of the guide rod 14 , and one end of the spring 13 is fixed to the surface of the circular limiting plate 19 .

[0030] See also Figure 2 In this embodiment, the limiting member is set as a circular limiting plate 19, which can not only limit the spring 13 and the connecting rod 11, but also increase the connection strength between the spring 13 and the limiting member to prevent the spring 13 from detaching from the surface of the guide rod 14.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
