[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figures 1 to 4 As shown, this embodiment provides a safety door device with a locking mechanism, including: a support frame 1 with a first groove and a second door panel hinged thereto for supporting the device; a first door panel 2, one end of which is hinged to the second door panel; a folding assembly including sliders 4 rotatably connected to the upper and lower sides of the first door panel 2, and sliders 4 slidably connected to the first groove on the support frame 1; a locking assembly including a limiting rod 5 fixedly connected to the first door panel 2, and a clamping block 6 slidably connected to the support frame 1 for locking; a rotating assembly including a turntable 8 rotatably connected to the support frame 1 via a rotating shaft, and a knob 10 slidably connected to the rotating shaft of the turntable 8; and an external expansion assembly including a control panel 14 arranged on the support frame 1.

[0031] In this embodiment, the support frame 1 supports the device, the door panel 1 2 is hinged to the door panel 2, the slider 4 of the folding component slides in the slide groove 1 to make the door panel 1 foldable, the limiting rod 5 and the clamping block 6 of the locking component cooperate to lock, the turntable 8 and the knob 10 of the rotating component are used to operate the lock, and the control panel 14 of the external extension component is used for external control.

[0032] Specifically, the folding assembly includes a pull ring 3, which is arranged on the surfaces of door panel 1 2 and door panel 2.

[0033] Among them, the pull ring 3 is used to pull the door panel 1 2 and the door panel 2 to assist in the folding operation.

[0034] Specifically, the locking component includes: a second slide groove 9, which is formed on the surface of the turntable 8 and is arranged in two symmetrical sets; and a sliding post 7, one end of which is slidably connected to the second slide groove 9 and the other end is set at the bottom of the clamping block 6.

[0035] In a preferred embodiment, when the turntable 8 rotates, the slide groove 2 9 drives the sliding column 7 to move, causing the clamping block 6 to slide, thereby locking or unlocking.

[0036] Example 2

[0037] Specifically, the rotating assembly includes: a spring 11, one end of which is connected to the support frame 1 and the other end of which is connected to the knob 10; a locking block 12, which is arranged on the knob 10 and engages with a hole in the support frame 1; and a protrusion 13, which is set on the rotating shaft of the turntable 8 and is slidably connected to the knob 10.

[0038] It should be noted that when the knob 10 pulls up the spring 11, the locking block 12 disengages from the hole. Rotating the knob 10 drives the turntable 8 to rotate through the protrusion 13. After being released, the spring 11 causes the locking block 12 to engage and fix in the hole.

[0039] Specifically, the external expansion components include: a detection device 15, arranged inside the support frame 1, for detecting opening and closing; and an indicator light 16, arranged on the top of the support frame 1, for displaying the status.

[0040] In addition, the detection device 15 uses a door magnetic sensor to detect the opening and closing status of the door, and the indicator light 16 displays the corresponding status.

[0041] It should also be understood that the control panel 14 and indicator lights 16 are common knowledge in the field. They are used without modification, so the control method and circuit connection will not be described in detail.

[0042] Example 3

[0043] Specifically, the top of the limiting rod 5 is provided with a cylindrical head, which can be locked to restrict forward and backward movement.

[0044] It should be noted that after locking, the cylindrical head restricts the door panel from moving forward and backward.

[0045] Specifically, the second slide 9 is designed to be arc-shaped, which can convert rotation into linear motion.

[0046] It should also be understood that the rotation of turntable 8 is converted into the linear motion of sliding column 7, which drives clamping block 6 to slide.

[0047] In use, the user first pulls the knob 10 outward and rotates it 90 degrees. Under the action of the spring 11, it resets inward and locks into the fixed hole. The rotation of the knob 10 drives the turntable 8 to rotate through the rotating shaft. The sliding column 7 at the bottom of the clamping block 6 slides on the second slide groove 9, controlling the clamping block 6 to separate to both sides, thereby unlocking it. At this time, pulling the pull ring 3 causes the slider 4 to slide on the first slide groove on the support frame 1, and the door panel 2 hinges to the second door panel and folds inward. The limit rod 5 set on the door panel 2 moves with the door panel 2. A detection device 15 is set inside the support frame 1. The sensing element of the detection device 15 changes with the opening and closing state of the door panel 2. The control panel 14 directly reads the on / off state of the sensing element through the input interface. The indicator light 16 is directly connected to the output port of the control panel 14 and is controlled by the main control chip. When the control panel 14 receives an opening or closing signal, the control signal light displays red or green, so the user can know whether there are other users performing maintenance operations or placing materials inside.

[0048] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
