Detailed Implementation

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] This embodiment provides a blocking structure for a vent on a door, which is used to install on a door panel 100 having a vent 101, see reference. Figure 1 As shown, the shielding structure includes a support device 200 and a shielding member; the support device 200 is disposed on the door panel 100, the shielding member is disposed on the support device 200, and the shielding member is configured to be spaced apart from the door panel 100; and the vertical projection of the vent 101 on the shielding member is within the range of the shielding member.

[0022] Specifically, in this embodiment, the support device 200 is used to create a predetermined gap between the shielding member 300 and the door panel 100; and the vertical projection of the vent 101 on the shielding member 300 within the range of the shielding member 300 means that when the shielding member 300 moves along the direction perpendicular to the door panel 100 to the vent 101, the shielding member 300 can completely cover the vent 101.

[0023] In this embodiment, by setting the shielding component 300, on the one hand, it can prevent outsiders from looking directly at the outside of the door through the ventilation opening 101, thus preventing privacy leaks; on the other hand, the air outside the door can enter the inside of the door panel 100, i.e., the room, through the gap between the door panel 100 and the shielding component 300, thus enabling the room to have a better ventilation effect.

[0024] refer to Figure 2 As shown, the support device 200 of this embodiment includes a telescopic member disposed on the door panel 100 and a mounting member 220 disposed on the top of the telescopic member. As the telescopic member extends and retracts, the mounting member 220 can move closer to or further away from the door panel 100. A shielding member 300 is disposed on the mounting member 220. That is, in this embodiment, the shielding member 300 is disposed on the mounting member 220 and can move closer to or further away from the door panel 100 as the telescopic member extends and retracts, thereby adjusting the distance between the shielding member 300 and the door panel 100, thereby adjusting the ventilation effect of the vent 101.

[0025] In terms of specific structure, refer to Figure 1 and Figure 2 As shown, the telescopic component in this embodiment includes a first cylindrical body 211 and a telescopic rod. The telescopic rod is inserted into the first cylindrical body 211, and a damping pad is provided between the telescopic rod and the inner wall of the first cylindrical body 211. In this embodiment, by providing the first cylindrical body 211 and the telescopic rod, the distance between the shielding component 300 and the door panel 100 can be adjusted by the user pulling or pushing the telescopic rod. By providing a damping pad between the telescopic rod and the inner wall of the first cylindrical body 211, the telescopic rod can be kept in its current position by the friction between the damping pad and the telescopic rod after the user stops pulling or pushing it, thus preventing the shielding component 300 from moving unexpectedly.

[0026] The structure of a shielding member 300 in this embodiment is as follows: Figure 2As shown, support devices 200 as described above are respectively provided on the upper and lower sides of the vent 101, and each support device 200 includes a guide rod 221, the length direction of which is parallel to the width direction of the door panel 100. The shielding member 300 in this embodiment is made of a soft material, such as fabric or plastic. Several sliding members that can slide on the guide rod 221 are provided at both ends of the shielding member 300. The shielding member 300 can unfold as the sliding members move away from each other and retract as the sliding members move closer together.

[0027] By providing the aforementioned shielding member 300, the shielding member 300 can be extended by sliding the sliding members in opposite directions to block the vent 101, thereby protecting privacy inside the door. Conversely, the sliding members can be retracted by sliding them in opposite directions to close the window panel 400 provided for the vent 101.

[0028] refer to Figure 2 As shown, the shielding member 300 has a plurality of through holes, and the aforementioned sliding members are sliding rings installed in each of the through holes, with each sliding ring sleeved on the guide rod 221. In some embodiments, each sliding member may also be a hook connected to the shielding member 300 and capable of sliding on the guide rod 221.

[0029] In some embodiments, the structure of the shielding member 300 is as follows: Figure 3 As shown, support devices 200 are provided on two opposite sides of the vent 101. One of the support devices 200 includes a rotatable rod 230, which will be referred to as the first support device 200 for ease of description. The aforementioned shielding member 300 is made of soft material. One end of the shielding member 300 is connected to the rod 230 and can be rolled up onto or released from the rod 230 as it rotates. A connecting member 310 is provided on the other end of the shielding member 300 relative to the end connected to the rod 230. The connecting member 310 can be connected to or separated from the other of the two support devices 200, which will be referred to as the second support device 200.

[0030] In this embodiment, under normal conditions, the shielding member 300 is rolled up on the rod 230, without obstructing the vent 101. When needed, the free end of the shielding member 300 can be pulled until the connecting member 310 on the free end of the shielding member 300 connects to the second support device 200. At this time, the shielding member 300 obstructs the vent 101. After the connecting member 310 separates from the second support device 200, the shielding member 300 can be rolled up on the rod 230 again. For example, a coil spring can be installed on the rod 230 so that the rod 230 can rotate automatically to roll up the shielding member 300. The structure and installation of the coil spring can refer to the prior art, and will not be described in detail here. Since it does not affect the understanding, the coil spring is not shown in the accompanying drawings of this embodiment. In this embodiment, the connecting member 310 is a hook, and the second support device 200 is provided with a connecting rod 240 that can be connected to the hook.

[0031] In some embodiments, reference Figure 4 As shown, the shielding member 300 is made of a rigid material, such as a wooden board. The shielding member 300 is slidably mounted on the door panel 100, and can slide close to the door panel 100 to block the vent 101, and can slide away from the door panel 100 to open the vent 101. When the shielding member 300 is made of this wooden material, it can replace the existing window panel 400 hinged to the door panel 100. For specific structural details, refer to... Figure 4 As shown, a second cylinder 250 is provided on the door panel 100, and a sliding rod 320 that can slide within the second cylinder 250 is provided on the shielding member 300. The sliding of the sliding rod 320 within the second cylinder 250 guides the sliding of the shielding member 300. To prevent the shielding member 300 from moving unexpectedly, a damping pad (not shown in the figure) is also provided between the sliding rod 320 and the second cylinder 250.

[0032] In this embodiment, a lock body is also installed between the shielding member 300 and the door panel 100 to lock the position between the shielding member 300 and the door panel 100 when the shielding member 300 is closed, preventing the shielding member 300 from being pushed from the outside of the door. It should be noted that the lock body can adopt an existing lock structure, such as a bolt lock. Since this does not affect the understanding, the lock is not shown in the accompanying drawings of this embodiment.

[0033] In this embodiment, the ratio between the area S1 of the side surface of the space between the shielding member 300 and the door panel 100 and the area S2 of the vent 101 is 0.8 to 1.2. Specifically, area S1 refers to the area of ​​the side surface of the three-dimensional shape formed with the end face of the shielding member 300 closest to the door panel 100 as the base and the distance between the shielding member 300 and the door panel 100 as the height. For example, when the shielding member 300 is square, the three-dimensional shape is a cuboid, and area S1 is the sum of the areas of the four side surfaces of the cuboid; when the shielding member 300 is circular, the three-dimensional shape is a cylinder, and area S1 is the area of ​​the side surface of the cylinder.

[0034] In this embodiment, since the air outside the door panel 100 enters the inside of the door panel 100 through the vent 101 and then through the gap between the shielding member 300 and the door panel 100, by setting the area ratio between 0.8 and 1.2, the area of ​​the vent 101 is approximately equal to the area between the shielding member 300 and the door panel 100, which sufficiently satisfies the ventilation effect of the vent 101. If the ratio is too small, the distance between the shielding member 300 and the door panel 100 will be too close, affecting the ventilation effect of the vent 101. If the ratio is too large, the distance between the shielding member 300 and the door panel 100 will be too far, requiring the shielding member 300 to have a larger area to protect the privacy inside the door panel 100, affecting the aesthetics.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
