[0045] This utility model provides a protective door. By setting a detachable support for the connecting components and connecting the first and second door rails, the protective door can be applied to door frames of various sizes, making it widely applicable. In addition, the protective door is designed with a 90° stopping function. When the door is opened to 90°, it can remain open for easy passage. When the door is not opened to 90°, it will automatically close, ensuring both convenience and safety.

[0046] Reference Figures 1 to 15 This embodiment provides a protective door, including a door body 1. A first fixing device is provided on one side of the door body 1, and the door body 1 can be movably connected to an external object through the first fixing device. A locking structure 2 is provided on the other side of the door body 1, and the door body 1 can be detachably connected to an external object through the locking structure 2.

[0047] In this embodiment, the door frame 7 is used as the external object for description. One side of the door body 1 is movably connected to the door frame 7, and the other side is detachably connected to the door frame 7. In practical applications, the door body 1 can be connected to other buildings.

[0048] The door body 1 includes a first door frame 11 and a second door frame 12. The first door frame 11 and the second door frame 12 are arranged in parallel and at least partially overlap. The overlapping part of the first door frame 11 and the second door frame 12 is connected and fixed by a connecting component 6.

[0049] In this embodiment, the connecting component 6 includes a first pressing plate 61, a second pressing plate 62, and a screw 64 for connecting the first pressing plate 61 and the second pressing plate 62. The first pressing plate 61 and the second pressing plate 62 have the same structure and are symmetrically arranged.

[0050] Preferably, both the first gate 11 and the second gate 12 include a hollow frame 13 and a protective post 14 connecting the two opposite frames 13.

[0051] Furthermore, both the first pressing plate 61 and the second pressing plate 62 include a horizontally positioned central section and arc-shaped protrusions 63 at both ends of the central section. A screw 64 connects the central sections of the first pressing plate 61 and the second pressing plate 62, forming a gap 65 between the screw 64 and the arc-shaped protrusions 63. There are two gaps 65, one for the frame 13 of the first door frame 11 to pass through, and the other for the frame 13 of the second door frame 12 to pass through.

[0052] The first gate 11 and the second gate 12 are fixedly connected by the connecting component 6, preventing relative displacement between them and ensuring the protective effect of the gates, thus preventing infants or pets from pushing the gate 1 out. The screw 64 allows for a detachable connection between the first gate 11 and the second gate 12, enabling easy disconnection and adjustment of their relative positions to adjust the width of the gate 1.

[0053] Preferably, the first fixing device includes a first fixing component 31, which includes a first connector 311 and a second connector 312. The first connector 311 and the second connector 312 are hinged together. The first connector 311 is connected to the door frame 7, and the second connector 312 is connected to the first door rail 11.

[0054] Furthermore, the first connector 311 includes a positioning post 3111, the center of which is provided with a first shaft hole 3112, the end of which is provided with a first groove 3113, and one side of the first groove 3113 is provided with a first guide slope 3114 extending axially toward the positioning post 3111. The second connector 312 includes a first rotating shaft 3121 and a positioning block 3122 provided on the side of the first rotating shaft 3121.

[0055] The first guide slope 3114 of the positioning post 3111 is located on the side of the positioning post 3111 near the second connector 312. When the first rotating shaft 3121 is inserted into the first shaft hole 3112 and the positioning block 3122 is engaged in the middle of the first guide slope 3114, the door 1 is in the closed state. When the door 1 is rotated, the positioning block 3122 slides along the first guide slope 3114 until it slides into the first groove 3113, at which point the door 1 is at its maximum open angle and remains open. When the user applies a certain external force to the door 1, causing the positioning block 3122 to disengage from the first groove 3113, the positioning block 3122 will slide down the first guide slope 3114 to the middle of the first guide slope 3114, and the door will return to the closed state.

[0056] By setting the positioning post 3111, the first groove 3113 and the first guide slope 3114, the door 1 can be kept in a closed or open state. When the door 1 is opened and the positioning block 3122 does not slide into the first groove 3113, the door 1 can be automatically closed, which improves safety and ease of use.

[0057] Preferably, the middle part of the first guide slope 3114 forms a 90-degree angle with the first groove 3113, which means that the maximum angle at which the door 1 can be opened is 90 degrees, and the door 1 can remain in the open state; until an external force is applied to the door 1, causing the positioning block 3122 to disengage from the first groove 3113, the door 1 will automatically close.

[0058] The first connector 311 is provided with a fixing part 3115, and the fixing part 3115 is provided with a first mounting hole 3116. The first mounting hole 3116 is fixedly connected to the door frame 7 by screws, thus fixing the first connector 311 to the door frame 7. The second connector 312 is provided with a second connecting tube 3123, and the second connecting tube 3123 is provided with a threaded hole 3124. The frame 13 of the first door frame 11 is a hollow structure. The second connecting tube 3123 is inserted into the frame 13 of the first door frame 11 and is connected by screws and locking.

[0059] Furthermore, the first fixing device also includes a second fixing component 32, which includes a third connector 321 and a fourth connector 322, with the third connector 321 and the fourth connector 322 hinged together.

[0060] Specifically, the third connector 321 is provided with a second shaft hole 3211, and the fourth connector 322 is provided with a second rotating shaft 3221. The second rotating shaft 3221 is inserted into the second shaft hole 3211 to achieve hinge connection between the third connector 321 and the fourth connector 322. The third connector 321 is provided with a second mounting hole 3212, which is fixed to the door frame 7 by screws, thus fixing the third connector 321 to the door frame 7. The fourth connector 322 is provided with a third mounting hole 3222, which is connected to the first door frame 11 by screws, thus fixing the fourth connector 322 to the first door frame 11.

[0061] The first fixing component 31 and the second fixing component 32 are longitudinally distributed and together fix the first door frame 11 to the door frame 7, providing stable support for the door 1 during the opening or closing process.

[0062] Preferably, the protective door further includes a second fixing device 4, which includes a fifth connector 41. The fifth connector 41 has a first slot 42 and a fourth mounting hole 43. The fourth mounting hole 43 and the door frame 7 are connected by screws to fix the fifth connector 41 to the door frame 7. A locking structure 2 is provided on the side of the door body 1. The locking structure 2 includes a spring buckle 21, which can be inserted into the first slot 42 to realize the connection between the second door frame 12 and the door frame 7.

[0063] Furthermore, the protective door also includes a third fixing device 5. The third fixing device 5 includes a sixth connector 51 and a seventh connector 52. The sixth connector 51 has a second slot 511 and a fifth mounting hole 512. The fifth mounting hole 512 is fixedly connected to the door frame 7 by screws, thus fixing the sixth connector 51 to the door frame 7. The seventh connector 52 has a second locking block 521 and a sixth mounting hole 522. The sixth mounting hole 522 is fixedly connected to the second door frame 12 by screws, thus fixing the seventh connector 52 to the second door frame 12. The second locking block 521 can be inserted into the second slot 511.

[0064] The second fixing device 4 and the third fixing device 5 are longitudinally distributed and together connect the second door frame 12 to the door frame 7.

[0065] Furthermore, the locking structure 2 also includes a housing 22 and a pressing structure 225. The housing 22 has an installation groove 221 inside, and the snap fastener 21 is located in the installation groove 221. A cover plate 222 is provided on the outside of the installation groove 221. The snap fastener 21 includes an elastic element 211 and a first locking block 212. The first locking block 212 is located between the elastic element 211 and the cover plate 222. One end of the first locking block 212 has a protrusion 2121 that extends to the outside of the cover plate 222. The cover plate 222 is used to restrict the snap fastener 21 within the installation groove 221.

[0066] Specifically, the top of the first locking block 212 is provided with a second groove 2122, the side wall of the second groove 2122 is provided with a second guide slope 2123, the pressing structure 225 includes a pushing block 2251, the pushing block 2251 is provided with a third guide slope 2252 adapted to the second guide slope 2123, and the pushing block 2251 is located above the second groove 2122.

[0067] When the user applies a downward force to the pressing structure 225, the pushing block 2251 will be inserted into the second groove 2122, and the third guide slope 2252 will cooperate with the second guide slope 2123 to push the first locking block 212 to move away from the seventh connector 52. The elastic element 211 is compressed, causing the snap 21 to disengage from the first slot 42. At the same time, the second locking block 521 disengages from the second slot 511, and the second door 12 can be opened relative to the door frame 7. When the user cancels the force applied to the pressing structure 225, the first locking block 212 will move towards the fifth connector 41 under the action of the elastic restoring force provided by the elastic element 211 and be inserted into the first slot 42. The second locking block 521 will be inserted into the second slot 511, and the second door 12 will be in a relatively fixed state relative to the door frame 7.

[0068] Furthermore, the second door frame 12 is provided with a plurality of horizontally distributed first connecting holes 121, and the outer shell 22 includes an upper shell 223 and a lower shell 224. The upper shell 223 is provided with a plurality of connecting posts 2231, and the lower shell 224 is provided with a plurality of second connecting holes 2241. The first connecting holes 121, the connecting posts 2231 and the second connecting holes 2241 are adapted to each other. The connecting posts 2231 pass through the first connecting holes 121 on the second door frame 12 and are inserted into the second connecting holes 2241 to realize the connection between the second door frame 12 and the locking structure 2.

[0069] Furthermore, the door body 1 also includes a guide structure 15. The guide structure 15 includes a base 151, which is provided with a first connecting pipe 152 and a slide groove 153. The first connecting pipe 152 is parallel to the slide groove 153, and the slide groove 153 has openings at both ends. The outer periphery of the first connecting pipe 152 is adapted to the inner periphery of the frame 13 of the first door frame 11 or the second door frame 12, and the inner periphery of the slide groove 153 is adapted to the outer periphery of the frame 13 of the first door frame 11 or the second door frame 12.

[0070] Understandably, the first connecting pipe 152 is inserted into the frame 13 of the first door frame 11 and fixedly connected to the first door frame 11 by screws. The frame 13 of the second door frame 12 is engaged in the slide groove 153. When it is necessary to adjust the relative position of the first door frame 11 and the second door frame 12, the second door frame 12 can slide along the slide groove 153, which provides support and guidance for the second door frame 12. Alternatively, the first connecting pipe 152 can be inserted into the frame 13 of the second door frame 12 and fixedly connected to the second door frame 12, with the first door frame 11 engaged in the slide groove 153.

[0071] It is understandable that the first door frame 11 and the second door frame 12 together form the door body 1. By adjusting the relative positions of the first door frame 11 and the second door frame 12, the width of the door body 1 can be adjusted to suit door frames 7 of different sizes, such as main gates, outdoor doors, stairwells, and courtyard gates. When the width of the door body 1 is smaller than the width of the door frame 7, since the first door frame 11 is connected to the door frame 7 through the first fixing device, the width of the door body 1 can only be adjusted by moving the second door frame 12. It should be noted that the first door frame 11 and the second door frame 12 are the same size. When the first door frame 11 and the second door frame 12 completely overlap, the door body 1 is at its narrowest width.

[0072] The specific width adjustment steps include:

[0073] Disassemble the connecting component 6 connecting the first door frame 11 and the second door frame 12, so that the first door frame 11 and the second door frame 12 are in a state of relative movement; move the second door frame 12 away from the first door frame 11 until the locking device on the second door frame 12 can be inserted into the second fixing device 4 on the door frame 7. At this time, the first door frame 11 and the second door frame 12 still have overlapping parts; finally, fix the overlapping parts of the first door frame 11 and the second door frame 12 through the connecting component 6 to prevent them from sliding. The width adjustment work is now complete.

[0074] It is understood that those skilled in the art can combine various implementation methods in the above embodiments under the guidance of the above examples to obtain technical solutions with multiple implementation methods.

[0075] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
