Fig. 2 is a schematic plan view of a wall bushing in an open state according to an embodiment of the present disclosure; fig. 3 is a schematic plan view of a wall bushing in a half-open state according to an embodiment of the present disclosure; fig. 4 is a schematic plan view of a wall bushing in a closed state according to an embodiment of the present application. As shown in fig. 2 to 4, the cover body 200 of the present embodiment is slidably connected to the main body 100, and specifically slides along the circumferential direction of the main body 100, and the cover body 200 slides to expose the avoiding opening 140 on the main body 100, or the cover body 200 slides to cover the avoiding opening 140 to form an annular structure together with the main body 100.

When a pipeline or a line needs to be placed in the wall-through sheath, the cover body 200 can slide to expose the avoiding opening 140 on the main body 100, that is, the cover body 200 can slide to the state shown in fig. 2, the pipeline or the line can be placed in the wall-through sheath through the avoiding opening 140, after placement is completed, the cover body 200 can slide to cover the avoiding opening 140 to form an annular structure together with the main body 100, that is, the cover body 200 can sequentially slide to the states shown in fig. 3 and 4 to form protection in the circumferential direction of the pipeline or the line.

When it is necessary to remove the pipe or line from the wall bushing, the cover body 200 can be slid to expose the escape opening 140 of the main body 100, that is, the cover body 200 can be slid to the state of fig. 2, and the pipe or line can be removed from the escape opening 140.

Therefore, the cover body 200 can be mounted and dismounted only by sliding on the main body 100, the operation is simple and convenient, and the mounting efficiency of electrical appliances such as a split air conditioner can be improved.

It should be noted that only one pipeline can be arranged in the wall-through sheath in a penetrating manner, a plurality of pipelines can also be arranged in the wall-through sheath in a penetrating manner, and a gap between the pipeline and the inner side wall of the wall-through sheath can be filled with sealant so as to achieve the purposes of wind prevention and insect prevention.

The color of the sealant close to the wall surface can be selected, for example, a gap between the pipeline and the inner side wall of the wall penetrating sheath can be filled with white sealant, so that the tidiness of the wall surface is improved, and the wall surface is more attractive.

In addition, the wall-through sheath can be made of plastics, so that the wall-through sheath is convenient to manufacture, low in manufacturing cost and rich in plastic color, and the wall-through sheath can also be made into a color similar to the color of the wall surface, so that the installation performance of the wall-through sheath is improved.

As shown in fig. 1 and 2, the main body 100 may be provided with an abutting portion 150, the abutting portion 150 is located in a middle area of the main body 100 in the circumferential direction, the abutting portion 150 protrudes from the surface of the main body 100, and two circumferential ends of the abutting portion 150 are used for abutting against corresponding ends of the cover body 200. The abutting portion 150 can limit the rotation range of the cover body 200, so as to reduce the distance required by the cover body 200 to completely cover the avoidance opening 140, reduce the action time of an installer, and achieve the purposes of simplifying the operation and improving the installation efficiency.

For example, the shape and size of the abutting portion 150 may be matched with the shape and size of the cover 200, so that when the cover 200 completely covers the avoidance opening 140, the ring structure formed by the cover 200 and the main body 100 is a symmetrical structure, which has an attractive appearance and can improve the installation performance of the wall bushing.

As shown in fig. 4, when the cover body 200 covers the avoiding opening 140, an overlapping region (i.e., a region outlined by a dashed line in fig. 4) may be formed between two circumferential ends of the cover body 200 and two circumferential ends of the main body 100 to ensure that the cover body 200 can completely cover the avoiding opening 140, and the cover body 200 and the main body 100 contact each other in the overlapping region, and friction force exists between the two, and the friction force can keep the cover body 200 at a position covering the avoiding opening 140, that is, the friction force can keep the cover body 200 in a closed state to prevent the cover body 200 from being automatically opened due to gravity and other factors after being closed.

In some examples, the bypass opening 140 may correspond to a central angle of 90-180 °. The central angle corresponding to the avoidance opening 140 is larger than 90 degrees, so that the size of the avoidance opening 140 is enough to enable a pipeline or a line to pass through smoothly; the central angle corresponding to the avoiding opening 140 is smaller than 180 degrees, so that the length of the main body 100 in the circumferential direction is not smaller than the length of the cover body 200 in the circumferential direction, the cover body 200 can slide on the main body 100, the central angle corresponding to the cover body 200 is also approximately the same as the central angle corresponding to the avoiding opening 140, the central angle corresponding to the cover body 200 is at least not larger than 270 degrees, and the enough avoiding opening 140 can be exposed after the cover body 200 is opened.

In practical applications, the central angle corresponding to the bypass opening 140 may be determined according to the diameter of the pipeline or the route, for example, the central angle corresponding to the bypass opening 140 may be 100 ° or 120 °, and the like.

In order to increase the friction between the cover body 200 and the main body 100, a surface of the main body 100 facing the cover body 200 may be provided with a region having a relatively large roughness, which is defined as a rough region in the present embodiment, for example, a partial region of the surface of the main body 100 facing the cover body 200 is a rough region, and the rough region is disposed near the avoidance opening 140; alternatively, the rough region covers the entire region of the surface of the main body 100 facing the cover 200, and the surface of the main body 100 is rough, so as to prevent the cover 200 from being automatically opened due to gravity or the like after being closed.

For example, the surface of the cover 200 facing the main body 100 may also be provided with rough areas, and the rough areas are disposed near two ends of the cover 200; alternatively, the rough area covers the entire area of the surface of the cover 200 facing the main body 100, and the surface of the cover 200 is rough, so as to prevent the cover 200 from being automatically opened due to gravity or the like after being closed.

Fig. 5 is a schematic cross-sectional view of a wall bushing according to an embodiment of the present disclosure. As shown in fig. 1 and 5, the cover 200 can be slidably connected to the side of the main body 100 away from the wall surface.

It is understood that, at this time, the abutting portion 150 may protrude outward from the surface of the main body 100, that is, the abutting portion 150 may protrude toward the side of the main body 100 away from the wall surface, so that the end of the cover 200 can abut against the abutting portion 150.

Illustratively, the cover body 200 may include a main cover plate portion 210, an inner sidewall portion 220, and an outer sidewall portion 230. Wherein, inside wall portion 220 and lateral wall portion 230 connect respectively in the radial ascending inboard edge and the outside limit of main apron portion 210, the side surface contact that deviates from main apron portion 110 of inside wall portion 220 and interior plate portion 120, the side surface contact that deviates from main apron portion 110 of lateral wall portion 230 and lateral plate portion 130, and the one end of keeping away from main apron portion 210 of inside wall portion 220 and lateral wall portion 230 all has turn-ups 240, turn-ups 240 turns over towards one side at main apron portion 210 place and turns over.

As shown in fig. 5, in some examples, the flange 240 may be horizontally turned toward the inner panel 120 (i.e., inward), so as to limit the relative position between the main body 100 and the cover 200.

In other examples, the flange 240 may include a horizontal portion and a vertical portion (not shown), the horizontal portion is formed by being folded toward the inner panel 120 (i.e., inward), and the vertical portion is formed by being folded toward the main panel 110 (i.e., downward), so that the flange 240 may further limit the relative position between the main body 100 and the cover 200, and improve the stability of the connection between the main body 100 and the cover 200.

Furthermore, when the inner diameter of the wall opening is slightly smaller than the diameter of the annular structure formed by the inner side plate 120 of the main body 100 and the inner side wall 220 of the cover body 200, since the end surface of the inner side plate 120 is not abutted to the end surface of the inner side wall 220, the inner side plate 120 of the main body 100 and the inner side wall 220 of the cover body 200 can be retracted inward to fit the wall opening, and the friction between the wall bushing and the inner wall surface of the wall opening can be increased to prevent the wall bushing from falling out of the wall opening. Therefore, the wall-through sheath provided by the embodiment also has wider adaptability and higher stability.

In addition, in order to further increase the adaptability of the wall bushing, a plurality of notches (not shown) may be further provided on the inner side plate portion 120 of the main body 100 and the inner side wall portion 220 of the cover body 200 at intervals along the circumferential direction of the wall bushing to increase the inward contraction range of the inner side plate portion 120 of the main body 100 and the inner side wall portion 220 of the cover body 200.
