Detailed implementation manners
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0029] Embodiment:
[0030] Please refer to Figures 1-6 , a reinforced door frame for a steel art door, the structure of which includes a door frame 1 and a steel art door body 2 installed on the door frame 1. The door frame 1 includes a side reinforcing plate 11, a buffer mechanism 12 and a main reinforcing plate 13. Side reinforcing plates 11 are installed on both inner sides of the door frame 1, buffer mechanisms 12 connected to the door frame 1 are provided at both upper and lower ends of the two side reinforcing plates 11, and a main reinforcing plate 13 is installed at the upper beam inside the door frame 1.
[0031] In this embodiment, the main reinforcing plate 13 and the side reinforcing plate 11 have the same structure but different lengths, and can strengthen the door frame 1 through the main reinforcing plate 13 and the side reinforcing plate 11, increasing the strength of the door frame 1.
[0032] In this embodiment, the main reinforcement plate 13 includes a support plate 131, reinforcing ribs 132, a first arc plate 133 and a second arc plate 134. A support plate 131 is fixed inside the main reinforcement plate 13. Reinforcing ribs 132 connected to the main reinforcement plate 13 are connected to both sides of the support plate 131. The first arc plate 133 and the second arc plate 134 are symmetrically connected between the main reinforcement plate 13 and the reinforcing ribs 132. The arc portions of the first arc plate 133 and the second arc plate 134 are symmetrically arranged and in contact. When the main reinforcement plate 13 is impacted, it will forcefully squeeze the first arc plate 133 and the second arc plate 134. By virtue of the stability and load-bearing characteristics of the arc structures of the first arc plate 133 and the second arc plate 134, the compressive resistance of the main reinforcement plate 13 can be increased.
[0033] In this embodiment, the support plate 131 and the reinforcing ribs 132 on both sides can be connected and cooperated with the main reinforcement plate 13 to divide the main reinforcement plate 13 into several triangular structures. By virtue of the characteristics of high stability and strength of the triangular structure, the strengthening performance and strength of the main reinforcement plate 13 for the door frame 1 can be increased.
[0034] In this embodiment, the buffer mechanism 12 includes a bottom plate 21, a top block 22, spring dampers 23, sleeves 24, rotating seats 25, push rods 26 and extrusion seats 27. A top block 22 is provided directly above the bottom plate 21. Both the bottom plate 21 and the top block 22 are connected to the door frame 1. Two groups of spring dampers 23 are symmetrically provided between the bottom plate 21 and the top block 22. The tops of the two groups of spring dampers 23 are connected to the sleeves 24 located on the top block 22. A rotating seat 25 is installed on one side of each of the two sleeves 24. A push rod 26 is rotatably fitted on the rotating seat 25. The other end of the push rod 26 is connected to the extrusion seat 27.
[0035] In this embodiment, a buffer airbag 28 is connected between the two extrusion seats 27.
[0036] In this embodiment, sliding grooves 211 are symmetrically formed on the bottom plate 21.
[0037] In this embodiment, a slider 271 slidably fitted with the sliding groove 211 is provided at the bottom of the extrusion seat 27. An extrusion plate 272 is connected to one side of the extrusion seat 27 close to the buffer airbag 28. The extrusion plate 272 is in contact with the buffer airbag 28. When the extrusion seat 27 is pushed by the push rod 26, it will move forward and squeeze the buffer airbag 28 by means of the extrusion plate 272. Through the cooperation between the buffer airbag 28 and the spring dampers 23, the door frame 1 can be unloaded and buffered.
[0038] Working principle: When the steel art door frame is in use, a side reinforcing plate 11 and a main reinforcing plate 13 are installed inside the door frame 1. By means of the arc structures of the first arc plate 133 and the second arc plate 134 inside the reinforcing plate, when the door frame 1 is impacted, the stability and load-bearing capacity of the arc structures of the first arc plate 133 and the second arc plate 134 can increase the compressive resistance of the door frame 1. And through the support plate 131 and the reinforcing ribs 132 on both sides, the main reinforcing plate 13 can be divided into several triangular structures. By virtue of the high stability and strength characteristics of the triangular structure, the strength of the door frame 1 can be increased, making the door frame 1 not easily bent.
[0039] Buffer mechanisms 12 are installed at both the head and tail ends of the door frame 1. The spring damper 23 on the buffer mechanism 12 can buffer the impact force when the door frame 1 is impacted and squeezed. And when the spring damper 23 is squeezed and moves downward, it will drive the push rod 26 connected to it to protrude forward in the sliding groove 211 and squeeze the buffer airbag 28 in contact with it. Through the mutual cooperation between the buffer airbag 28 and the spring damper 23, the impact force received by the door frame 1 can be buffered and unloaded, increasing the buffering performance of the door frame 1.
