Description

Technical Field

[0001] This utility model relates to folding doors, specifically to a soundproof and heat-insulating folding door. Background Technology

[0002] In today's society, young people's lifestyles are becoming increasingly convenient, and ordering takeout has become a daily choice for many. However, there are significant safety hazards that cannot be ignored when receiving takeout.

[0003] Traditional doorways often require the entire door to be opened when receiving food deliveries, creating an opportunity for criminals. Delivery drivers or other unauthorized individuals may rush into the apartment while the door is open, posing a serious threat to the lives and property of those inside.

[0004] In recent years, there have been numerous cases of delivery workers or strangers committing crimes under the guise of food delivery or courier services. This has led to widespread concerns about personal safety while people enjoy the convenience of these services.

[0005] To address this issue, current door designs still need improvement in terms of security. Traditional pass-through windows are either too small to effectively pass larger items, or lack an effective one-way control mechanism, failing to ensure that only people inside can open the door outwards while people outside cannot push it inwards.

[0006] This often leaves people indoors facing a dilemma when receiving takeout or other items: either risk opening the door directly or forgo using the pass-through window and instead go downstairs to pick them up themselves, which is time-consuming and laborious.

[0007] Therefore, designing a pass-through window with a movable panel that can only be opened outwards by people inside and cannot be pushed inwards by people outside is of paramount importance for ensuring the safety of people inside, especially when receiving takeout or other items. Utility Model Content

[0008] To address the above problems, the following technical solutions are proposed:

[0009] A soundproof and heat-insulating folding door includes a door frame and door panels. The door panels include a first door panel and a second door panel, which are hinged together. The door frame includes an upper slide rail and a lower slide rail. The middle of the top of the first door panel and the second door panel are slidably connected to the upper slide rail by a sliding member, and the middle of the bottom of the first door panel and the second door panel are slidably connected to the lower slide rail by a sliding member. A pass-through window is provided on the first door panel, and the pass-through window includes a movable panel that opens outward in one direction.

[0010] Furthermore, the shape of the movable plate matches the transfer window, a limit block is set at the bottom of the transfer window on the inner side, the top of the movable plate is hinged to the first door leaf by a hinge, and the bottom of the movable plate abuts against the limit block.

[0011] Furthermore, a magnet is embedded on the side of the limiting block near the movable plate, and an adsorption component that cooperates with the magnet is installed on the bottom of the movable plate.

[0012] Furthermore, the movable panel is made of sound and heat insulation material.

[0013] Furthermore, a viewing window is provided at the top of the first door leaf, and soundproof and heat-insulating glass is installed inside the viewing window.

[0014] Furthermore, a handle is provided on the first door leaf.

[0015] The beneficial effects of this utility model are as follows:

[0016] This soundproof and heat-insulating folding door with a pass-through window offers numerous significant advantages. Firstly, its one-way opening mechanism effectively prevents delivery personnel or other unauthorized individuals from forcibly entering the room, providing reliable protection for the lives and property of those inside. This means that young people can enjoy convenient services like ordering takeout without constantly worrying about potential dangers when opening the door, allowing them to move around indoors with peace of mind.

[0017] Secondly, the shape of the movable panel fits perfectly with the pass-through window, ensuring ample space for passing items and solving the problem of traditional pass-through windows being too small to handle larger items. People inside can easily receive various items such as takeout and packages without being hindered by window size limitations.

[0018] Furthermore, the limiting block located at the bottom inner side of the pass-through window, along with the magnet and suction device between the bottom of the movable plate and the limiting block, ensures that the movable plate fits tightly when closed, making it difficult to be accidentally opened by external force. This robust closing mechanism further enhances the door's security, effectively resisting even strong external impacts or attempts to force it open.

[0019] In addition, the movable panel is made of sound and heat insulation materials, which can not only keep the room quiet and temperature stable when passing items, but also prevent external noise and heat from entering the room through the transfer window, thus improving the comfort of the indoor environment.

[0020] The soundproof and heat-insulating glass installed inside the viewing window allows people inside to observe the situation outside the door without opening it, to understand the status of items being delivered or the condition of people outside, and to provide a basis for deciding whether to open the movable panel.

[0021] The handle on the first door panel facilitates the opening and closing of the door, allowing people inside to more easily control the door's status. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] A soundproof and heat-insulating folding door includes a door frame 1 and door panels. The door panels include a first door panel 21 and a second door panel 22, which are hinged together. The door frame 1 includes an upper slide rail 11 and a lower slide rail 12. The middle of the top of the first door panel 21 and the second door panel 22 are slidably connected to the upper slide rail 11 via sliding members, and the middle of the bottom of the first door panel 21 and the second door panel 22 are slidably connected to the lower slide rail 12 via sliding members. A transfer window is provided on the first door panel 21, which includes a movable plate 213 that opens outward in one direction. The shape of the movable plate 213 matches the transfer window. A limit block 211 is provided on the inner side of the bottom of the transfer window. The top of the movable plate 213 is hinged to the first door panel 21, and the bottom of the movable plate 213 abuts against the limit block 211. A magnet 212 is embedded on the side of the limit block 211 near the movable plate 213, and an adsorption member 214 that cooperates with the magnet 212 is installed on the bottom of the movable plate 213. The movable panel 213 is made of sound and heat insulation material. A viewing window 3 is provided on the upper part of the first door leaf 21, and sound and heat insulation glass is installed inside the viewing window 3. A handle 4 is provided on the first door leaf 21.

[0029] The working principle of this utility model is as follows:

[0030] When this soundproof and heat-insulating folding door is in operation, the various components are closely linked.

[0031] When receiving takeout or other items, people inside approach the pass-through window on the first door panel 21. The movable panel 213 is opened by manually pushing the hinge at the top, rotating outwards around the hinge axis. Because the movable panel 213 is a one-way opening design, people outside cannot push it inwards from the outside.

[0032] As the movable plate 213 opens, its bottom gradually detaches from the limiting block 211. However, due to the attraction between the magnet 212 and the adsorption component 214, the movable plate 213 will not completely detach from the first door leaf 21 and will still maintain a certain connection and restriction.

[0033] Once the movable panel 213 is opened to the appropriate angle, outdoor personnel can place items inside the transfer window. After the transfer is completed, indoor personnel release the movable panel 213. Under the attraction of the magnet 212 and the adsorption component 214, and the obstruction of the limiting block 211, the movable panel 213 automatically returns to its original position and tightly abuts against the limiting block 211, thus closing the transfer window.

[0034] During the sliding process of the door panels, the top and bottom midpoints of the first door panel 21 and the second door panel 22 slide smoothly in the upper slide rail 11 and the lower slide rail 12 via sliding members. When it is necessary to fully open the door, the first door panel 21 and the second door panel 22 fold and unfold to both sides along the slide rails to achieve a spacious passage. When it is necessary to close the door, the door panels slide towards each other along the slide rails until they are fully closed.

[0035] During use, the soundproof and heat-insulating glass inside the viewing window 3 always maintains good soundproof and heat-insulating performance, allowing people inside to observe the situation outside the door through the glass without affecting the overall function of the door.

[0036] The design of handle 4 makes it easier and less strenuous for people inside the room to operate the door. Simply hold handle 4 and apply appropriate force to make the door slide or turn.

[0037] In one embodiment, the attraction force of the magnet 212 and the adsorption element 214 can be adjusted as needed. For example, when a stronger closing force is required, a stronger magnet 212 and a corresponding adsorption element 214 can be used to ensure that the movable plate 213 can be tightly closed under various conditions.

[0038] In another embodiment, the glass of the viewing window 3 can be made of smart dimming glass. When people inside need enhanced privacy, they can adjust the glass to an opaque state; and when they need to observe the situation outside the door, they can adjust it to a transparent state.

[0039] In another embodiment, the movable plate 213 of the pass-through window can be equipped with an automatic sensing and opening function. When a person inside approaches the pass-through window at a certain distance, the movable plate 213 automatically unlocks and opens slightly at a certain angle, making it easier for the person inside to push it open further, thus improving ease of use.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
