Description

Technical Field

[0001] The utility model relates to the technical field of doors, in particular to a single-leaf door with a steel structure having good safety. Background Art

[0002] Steel structure single leaf door is a common door type, mainly made of steel, with the characteristics of firmness, durability and beauty. This kind of door is usually used in industrial plants, warehouses, garages and other places that require large and strong doors. The frame of steel structure single leaf door is welded by steel sections, steel plates and other steel materials, and the door panel can be made of various materials such as color steel plate, stainless steel plate, aluminum plate, etc. Its opening method is generally manual or electric;

[0003] For example, the Chinese utility model patent disclosed by publication number CN213418873U: a wear-resistant steel structure door, the application pushes the rubber pad into the interior of the storage groove through its own plasticity. When the door body is closed and in contact with the door frame body, the rubber pad can support the door body, thereby avoiding the wear of the left side of the door body and the surface of the door frame body. Therefore, the application only reduces the wear of the door body by adding rubber pads during the application process. Since the door body in this application is roughly the same as other types of door structures, and only relies on the lock tongue and hinge of the lock to connect and limit the door frame body, when used in some occasions with explosion-proof requirements, because the hinges and locks are mainly designed to realize the opening and closing functions and locking functions of the door, rather than to withstand strong impact forces, when the door body is impacted, the hinges and locks may be damaged due to excessive force, resulting in the door body being unable to maintain a stable position, thereby affecting its impact resistance.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a single-leaf door with a steel structure having good safety, comprising a door frame 1 and a door body 2, the door body 2 further comprising a front door panel 3 and a rear door panel 6, a longitudinal support beam 4 is fixedly connected between the front door panel 3 and the rear door panel 6, two transverse support beams 5 are fixedly connected on both sides of the longitudinal support beam 4, a reinforcing column A7 is movably installed in the transverse support beam 5, a reinforcing column B8 is movably installed in the lower position of the longitudinal support beam 4, a fixing plate 9 is fixedly installed at the rear end of the rear door panel 6, an operating buckle 10 is movably installed at the rear end of the fixing plate 9, and the front door panel 3 is movably installed on one side of the door frame 1 through a plurality of hinges 11.

[0021] like Figure 2-Figure 3As shown, a plurality of fixing seats A12 are fixedly installed on the inner side of the longitudinal support beam 4, a fixing seat B13 is fixedly installed on the rear door panel 6 located at the bottom of the longitudinal support beam 4, a fixing seat A12 is also fixedly installed in the transverse support beam 5, and a fixing seat B13 is also fixedly installed on the rear door panel 6 located on one side of the transverse support beam 5. Fixing seats A12 and fixing seats B13 are respectively arranged in the longitudinal support beam 4 and the transverse support beam 5, which can provide basic guiding conditions for the movable installation of the reinforcing column A7 and the reinforcing column B8. The reinforcing column A7 is inserted in the fixing seats A12 and the fixing seats B13 in the corresponding transverse support beam 5, and the reinforcing column A7 located on one side of the fixing seat A12 is fixedly installed with a fixing ring 14, and the fixing seat B13 is arranged in the fixing seat B13. The reinforcing column A7 between the fixing seat A13 and the fixing ring 14 is also provided with a compression spring 15, two pressing blocks 16 are fixedly installed on the outer side of the reinforcing column B8, the reinforcing column B8 is inserted and installed in the fixing seat A12 and the fixing seat B13 in the longitudinal support beam 4, and the reinforcing column B8 located below one of the fixing seats A12 is also fixedly installed with a fixing ring 14, the reinforcing column B8 located between the fixing seat B13 in the longitudinal support beam 4 and the fixing ring 14 on the outer side of the reinforcing column B8 is also provided with a compression spring 15, and the two pressing blocks 16 are respectively placed between the corresponding two reinforcing columns A7, and by using the arrangement of the reinforcing column B8 and the two pressing blocks 16, the four reinforcing columns A7 can be moved synchronously when the reinforcing column B8 is operated;

[0022] like Figure 3-Figure 4 As shown, a groove seat 17 is fixedly installed at the rear end of the fixed plate 9, and two limit seats 18 are fixedly installed on the fixed plate 9 located above the groove seat 17. The two limit seats 18 are in an L-shaped structure arranged relatively to each other. A slot 19 is provided at the lower end of the operating buckle 10, and the operating buckle 10 is inserted and installed between the two limit seats 18, and the operating buckle 10 is fixedly connected to the reinforcement column B8 through a connecting block 20. With the help of the setting of the operating buckle 10 and the groove seat 17, the reinforcement column B8 can be operated to move vertically and radially in the longitudinal support beam 4, and the moved reinforcement column B8 can be limited.

[0023] It should be noted that the utility model is a single-leaf steel door with good safety. After the door body 2 is rotated into the door frame 1 through the hinge 11, the entire door body 2 is limited in the door frame 1 through the lock, and then the operating buckle 10 is pressed down between the two limiting seats 18. Then, the operating buckle 10 drives the reinforcing column B8 to move downward in the fixing seat A12 and the fixing seat B13 in the longitudinal support beam 4 through the connecting block 20. At the same time, the reinforcing column B8 also synchronously drives the two pressing blocks 16 to move downward. Since the two pressing blocks 16 are in an inverted trapezoidal structure, the two pressing blocks 16 synchronously squeeze and move the corresponding two reinforcing columns A7 to one side respectively. Therefore, the reinforcing column B8 compresses the compression spring 15 on the outside of the reinforcing column B8 toward the corresponding fixing seat B13 through the outer fixing ring 14, and the reinforcing column A7 also compresses the compression spring 15 on the outside of the reinforcing column B8 toward the corresponding fixing seat B13 in the transverse support beam 5 through its external fixing ring 14, so that one end of the reinforcing column A7 and the reinforcing column B8 are respectively inserted into the corresponding slots on the inner side of the door frame 1. At this time, the lower end of the operating buckle 10 also uses the card slot 19 to be inserted into the outer side of the inverted groove seat 17, so as to limit the reinforcing column B8, thereby utilizing four reinforcing columns A7 and one reinforcing column B8 to enhance the impact resistance of the entire door body 2.

[0024] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
