Detailed Implementation

[0023] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0024] like Figures 1 to 5 As shown in the figure, the present invention provides a stainless steel door with a protective structure, including a door frame 1. The door frame 1 is made of stainless steel and its main function is to fix the stainless steel door to the wall.

[0025] Furthermore, edge banding strips 2 are detachably connected to both sides of the door frame 1. The edge banding strips 2 are made of stainless steel. The main function of the edge banding strips 2 is to cover the edge of the door frame 1 to prevent it from being worn and scratched during use. The edge banding strips 2 can not only extend the service life of the door, but also maintain the good appearance of the door.

[0026] Furthermore, a door leaf 3 is rotatably connected to the door frame 1. The door leaf 3 is made entirely of stainless steel. A door lock 4 is detachably connected to the door leaf 3. The door lock 4 is fixed to the door leaf 3 by bolts and is used to fix the door leaf 3. A cavity is opened inside the door leaf 3, and a support plate 5 is movably connected inside the cavity. A drive assembly 6 is provided on the door leaf 3. The drive assembly 6 is used to drive the support plate 5.

[0027] Specifically, the drive assembly 6 includes a rotating wheel 601, which is rotatably connected to the cavity of the door leaf 3. One end of the rotating wheel 601 is fixedly connected to a ratchet 602, and the other end of the rotating wheel 601 is fixedly connected to a handle 603.

[0028] Furthermore, a drive rod 604 is fixedly connected to the outer wall of the rotating wheel 601. A slide rail is provided on the drive rod 604. A slide rod 605 is slidably connected in the slide rail. A transmission rod 606 is fixedly connected to the slide rod 605. The transmission rod 606 is fixedly connected to the support plate 5.

[0029] Specifically, by rotating the throttle 603, the rotating wheel 601 is driven to rotate. After the rotating wheel 601 rotates, the drive rod 604 is driven to rotate. After the drive rod 604 rotates, the slide rod 605 slides in the slide rail on the drive rod 604, thereby driving the transmission rod 606 to move, which in turn causes the support plate 5 to move.

[0030] Furthermore, a fixing pin 7 is fixedly connected to one side of the support plate 5, and a slot is provided on the door frame 1, in which the fixing pin 7 is movably connected.

[0031] Specifically, after the support plate 5 moves, it will drive the fixing pin 7 to move, so that the fixing pin 7 can be inserted into the slot of the door frame 1 to further fix the door leaf 3 and prevent the door from being forcibly broken.

[0032] Furthermore, the drive assembly 6 also includes a pawl 607, which is rotatably connected to the cavity of the door leaf 3. The pawl 607 is used to fix the ratchet 602, and a handle 608 is fixedly connected to one end of the pawl 607.

[0033] Furthermore, a cylinder 609 is fixedly connected inside the cavity of the door leaf 3. The cylinder 609 is sleeved on the handle 608. A spring 610 is provided inside the cylinder 609. One end of the spring 610 is fixedly connected to the inner wall of the cylinder 609, and the other end of the spring 610 is fixedly connected to the outer wall of the handle 608.

[0034] Specifically, when the handle 603 drives the wheel 601 to rotate, the ratchet 602 rotates as well. During the rotation of the ratchet 602, the pawl 607 will rotate. Under the action of the spring 610, the pawl 607 is always under force, so the ratchet 602 cannot reverse, thus fixing the support plate 5 and the fixing pin 7, thereby preventing external force from opening the door leaf 3. When the handle 608 is turned, the pawl 607 is disengaged from the ratchet 602, and the ratchet 602 can reverse, thereby disengaging the fixing pin 7 from the slot of the door frame 1, and thus allowing the door leaf 3 to be opened by the door lock 4.

[0035] Furthermore, a spring-loaded assembly 8 is provided on the other side of the support plate 5, and a hinge 9 is fixedly connected to one side of the door frame 1. The hinge 9 is fixedly connected to the door leaf 3, and the door leaf 3 is rotatably connected to the door frame 1 through the hinge 9.

[0036] Specifically, the rebound assembly 8 holds the support rod 801, which is fixedly connected to the inner wall of the cavity of the door leaf 3. The support rod 801 has a groove, and a guide rod 802 is slidably connected in the groove. The guide rod 802 is fixedly connected to the support plate 5 and is used to limit the movement of the support rod 801 to prevent the support rod 801 from being misaligned.

[0037] Furthermore, the spring rebound assembly 8 also includes a spring 803, one end of which is fixedly connected to the inner wall of the groove, and the other end of which is fixedly connected to the guide rod 802.

[0038] Specifically, during the process of opening the support plate 5, the guide rod 802 will be pulled, and the guide rod 802 will pull the spring 803 to move out of the groove. When the handle 608 is turned so that the pawl 607 disengages from the ratchet 602, the guide rod 802 will move inward into the groove due to the rebound force of the spring 803, thereby causing the support plate 5 and the fixing pin 7 to retract automatically, so that the door 3 can be opened quickly for escape in the event of an emergency.

[0039] Furthermore, when the support plate 5 is opened, it will support both sides of the door leaf 3, which can prevent external forces from damaging the door leaf 3 from the side. At the same time, the support rod 801 can also play a certain supporting role, strengthening the protective ability of the door leaf 3.

[0040] The working principle of this utility model is as follows:

[0041] This utility model is equipped with a support plate 5 and a drive assembly 6. By rotating the handle 603, the rotating wheel 601 is driven to rotate. After the rotating wheel 601 rotates, the drive rod 604 is driven to rotate. After the drive rod 604 rotates, the sliding rod 605 slides in the slide rail on the drive rod 604, thereby driving the transmission rod 606 to move, which in turn causes the support plate 5 to move. After the support plate 5 moves, the fixing pin 7 moves, so that the fixing pin 7 is inserted into the slot of the door frame 1, further fixing the door leaf 3, improving the protective ability of the stainless steel door, and ensuring the safety of residents.

[0042] This utility model is equipped with a spring-loaded component 8. When the support plate 5 is opened, it will pull the guide rod 802, which will pull the spring 803 to move out of the groove. When the handle 608 is turned so that the pawl 607 disengages from the ratchet 602, the guide rod 802 will move back into the groove due to the spring force of the spring 803, thereby causing the support plate 5 and the fixing pin 7 to retract automatically. This allows residents to quickly open the door 3 to escape in the event of an emergency.

[0043] 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
