When the pipe or line needs to be placed in the wall penetration sheath, the cover body can be slid to expose the avoidance opening on the main body, and the pipe or line can be inserted into the wall penetration sheath through the avoidance opening. After placement, the cover body is slid to cover the avoidance opening to form an annular structure together with the main body to provide protection in the circumferential direction of the pipe or line. The cover body only needs to be slid on the main body to complete the installation and disassembly of the wall penetration sheath, and the operation is simple and convenient. Among them, the main board includes a main board portion, an inner plate portion and an outer plate portion. The main board portion is a fan ring, and there is an avoidance opening between the two ends of the main board portion in the circumferential direction. The inner plate portion is connected to the inner arc edge of the main board portion, and the outer plate portion is connected to the outer arc edge of the main board portion. Both the inner plate portion and the outer plate portion extend toward the wall. The inner plate portion is penetrated into the wall hole and contacts the inner wall surface of the wall hole. The wall sheath can be fixed in the wall hole by the friction between the inner plate portion and the inner wall surface of the wall hole. The main board portion and the outer plate portion are exposed outside the wall hole, can block the wall hole, and have a certain installation function. When pushing or pulling the wall sheath into or out of the wall hole, the main board portion and the outer plate portion can be used as fulcrums, which is convenient for the installer to operate.

[0010] In a possible implementation, the cover is slidably connected to a side of the main body facing away from the wall.

[0011] In a possible implementation, the cover body includes a main cover plate portion, an inner sidewall portion, and an outer sidewall portion;

[0012] The inner wall portion and the outer wall portion are respectively connected to the radial inner edge and outer edge of the main cover portion, the inner wall portion contacts the surface of the inner plate portion on the side facing away from the main plate portion, and the outer wall portion contacts the surface of the outer plate portion on the side facing away from the main plate portion, and the ends of the inner wall portion and the outer wall portion away from the main cover portion both have flanges, which are folded toward the side where the main cover portion is located.

[0013] In a possible implementation, the cover is slidably connected to a side of the main body facing the wall.

[0014] In a possible implementation, the cover body includes a main cover plate portion, an inner wall portion, and an outer wall portion;

[0016] In one possible implementation, the limiting structure includes a stop wall, which extends out from the opposite side wall surfaces of the inner plate portion and the outer plate portion, and one end of the inner wall portion away from the main cover portion and one end of the outer wall portion away from the main cover portion respectively abut against the corresponding stop wall.

[0017] In one possible implementation, the limiting structure includes a sliding groove and a sliding bar. The sliding groove is arranged on the opposite side wall surfaces of the inner plate portion and the outer plate portion, and the sliding bar extends from the side surface of the inner wall portion facing away from the main cover portion and the side surface of the outer wall portion facing away from the main cover portion, and the sliding bar slides along the sliding groove.

[0018] In a possible implementation, the main body is provided with an abutment portion, which is located in the middle area of the main body in the circumferential direction and protrudes from the surface of the main body. The circumferential ends of the abutment portion are used to abut the corresponding ends of the cover body.

[0019] In a possible implementation, when the cover covers the avoidance opening, two circumferential ends of the cover and two circumferential ends of the main body have overlapping areas.

[0035] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0036] When various electrical appliances such as split air conditioners are installed on the wall, their pipes or lines need to pass through the wall hole. In order to protect the pipes or lines, a wall sheath is usually installed in the wall hole.

[0037] In the related art, wall penetration sheaths are mostly split-type designs, which usually include two half-ring parts. Both ends of the two half-ring parts are provided with a snap-on structure in the circumferential direction. The two half-ring parts are assembled together through the snap-on structure to form a ring-shaped structure to cover the inner wall surface of the wall hole, so as to prevent the pipes or lines passing through it from being damaged by the rough inner wall surface of the wall hole.

[0038] However, when installing the existing wall penetration sheath, it is necessary to place the pipe or wire on the inner side of the semi-ring member; after placement, the clamping structures at one end of the two semi-ring members are aligned in the circumferential direction, and external force is applied to connect the ends together; then, it is necessary to align the clamping structures at the other end of the two semi-ring members in the circumferential direction, and external force is applied to connect the ends together to form a ring structure, and the pipe or wire is located in the ring structure; finally, the wall penetration sheath is pushed into the wall hole to complete the installation.

[0039] Furthermore, for aesthetic reasons, the snap-fit structure is typically located on the side of the half-ring member facing the wall. Installers must face away from the wall and position the half-ring member away from the wall to observe the snap-fit structure and align the snap-fit structures of the two half-ring members. If the appliance to be installed is close to the wall, meaning the half-ring member cannot be moved away from the wall, the installer must face the wall and position themselves on the side of the wall sheath facing away from the wall. The installer cannot directly observe the snap-fit structure and must grope their way to align the snap-fit structures of the two half-ring members.

[0040] It can be seen that the existing wall-penetrating sheath is inconvenient to install and remove.

[0041] In view of this, an embodiment of the present application provides a wall penetration cover, which provides an avoidance opening on the main body and makes the cover body slidably connected to the main body. When it is necessary to place a pipe or line into the wall penetration cover, the cover body can slide to expose the avoidance opening on the main body, and the pipe or line can be placed into the wall penetration cover through the avoidance opening. After placement, the cover body is slid to cover the avoidance opening to form an annular structure together with the main body to provide protection in the circumferential direction of the pipe or line. The cover body only needs to slide on the main body to complete the installation and disassembly of the wall penetration cover, which is easy to operate.

[0042] The wall penetration sheath provided in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0043] Example 1

[0044] Figure 1 This is a three-dimensional schematic diagram of the wall sheath provided in Example 1 of this application. Figure 1 As shown, an embodiment of the present application provides a wall-penetrating sheath, which is installed in a wall hole. The wall-penetrating sheath includes a main body 100 and a cover body 200, wherein the main body 100 includes a main board portion 110, an inner plate portion 120 and an outer plate portion 130. The main board portion 110 is a fan-shaped ring, and an avoidance opening 140 is provided between the two ends of the main board portion 110 in the circumferential direction. The inner plate portion 120 is connected to the inner arc edge of the main board portion 110, and the outer plate portion 130 is connected to the outer arc edge of the main board portion 110. Both the inner plate portion 120 and the outer plate portion 130 extend toward the wall surface, and the inner plate portion 120 is penetrated into the wall hole and contacts the inner wall surface of the wall hole.

[0045] In this way, the wall sheath can be fixed in the wall hole by the friction between the inner plate portion 120 and the inner wall surface of the wall hole. The main plate portion 110 and the outer plate portion 130 are exposed outside the wall hole, which can cover the wall hole and have a certain installation function. Moreover, when the wall sheath needs to be pushed into or pulled out of the wall hole, the main plate portion 110 and the outer plate portion 130 can be used as a fulcrum to facilitate the operation of the installer.

[0046] It should be noted that the main plate portion 110 and the outer plate portion 130 are generally exposed indoors to be installed on indoor walls and to facilitate installation personnel to perform operations indoors.

[0047] Figure 2 A schematic plan view of the wall penetration sheath provided in Example 1 of the present application in an open state; Figure 3 A schematic plan view of the wall penetration sheath provided in Example 1 of the present application in a half-open state; Figure 4 This is a schematic plan view of the wall penetration sheath provided in the first embodiment of the present application in the closed state. Figure 2-Figure 4 As shown, the cover body 200 of this embodiment is slidably connected to the main body 100, and specifically slides along the circumference of the main body 100. The cover body 200 slides to expose the avoidance opening 140 on the main body 100, or the cover body 200 slides to cover the avoidance opening 140 to form an annular structure together with the main body 100.

[0048] When it is necessary to put the pipes and lines into the wall sheath, the cover 200 can slide to expose the avoidance opening 140 on the main body 100, that is, the cover 200 can slide to Figure 2 In the state shown, the pipe or line can be placed into the wall sheath through the avoidance opening 140. After placement, the cover 200 is slid to cover the avoidance opening 140 to form a ring structure together with the main body 100, that is, the cover 200 can be slid to Figure 3 、 Figure 4 The state shown is to form protection on the circumference of the pipeline or line.

[0049] When it is necessary to remove the pipe or line from the wall sheath, the cover 200 can slide to expose the avoidance opening 140 on the main body 100, that is, the cover 200 can slide to Figure 2 In the state, the pipe or line can be taken out from the avoidance opening 140.

[0050] It can be seen that the cover 200 only needs to slide on the main body 100 to complete the installation and removal of the wall-penetrating sheath, which is simple and convenient to operate and can improve the installation efficiency of electrical appliances such as split-type air conditioners.

[0051] It should be noted that only one pipe can be passed through the wall sheath, or multiple pipes can be passed through the wall sheath. The gap between the pipe and the inner wall of the wall sheath can be filled with sealant to achieve the purpose of wind and insect prevention.

[0052] Among them, the sealant can be selected with a color similar to the wall. For example, the gap between the pipe and the inner wall of the wall sheath can be filled with white sealant to improve the neatness of the wall and make the wall more beautiful.

[0053] In addition, the wall sheath can be made of plastic, which is easy to make and has low production cost. Plastic has rich colors and the wall sheath can also be made in a color similar to the wall surface to improve the installability of the wall sheath.

[0054] Combine Figure 1 and Figure 2 As shown, the main body 100 may be provided with an abutment portion 150, which is located in the middle region of the main body 100 in the circumferential direction. The abutment portion 150 protrudes from the surface of the main body 100, and the circumferential ends of the abutment portion 150 are used to abut the corresponding ends of the cover 200. The abutment portion 150 can limit the rotation range of the cover 200, thereby reducing the distance required for the cover 200 to rotate to fully cover the avoidance opening 140, reducing the installation time of the installer, and thus simplifying the operation and improving installation efficiency.

[0055] Exemplarily, the shape and size of the abutment portion 150 can match the shape and size of the cover body 200. In this way, when the cover body 200 completely covers the avoidance opening 140, the annular structure formed by the cover body 200 and the main body 100 is a symmetrical structure with an aesthetically pleasing appearance, which can improve the installability of the wall sheath.

[0056] like Figure 4 As shown, when the cover 200 covers the avoidance opening 140, there may be an overlapping area between the circumferential ends of the cover 200 and the circumferential ends of the main body 100 (ie Figure 4 The cover 200 and the main body 100 are in contact with each other in the overlapping area, and there is friction between the two. The friction can keep the cover 200 in the position covering the avoidance opening 140, that is, the friction can keep the cover 200 in the closed state to avoid the cover 200 from automatically opening due to factors such as gravity after it is closed.

[0057] In some examples, the central angle of the avoidance opening 140 may be 90°-180°. A central angle greater than 90° ensures that the avoidance opening 140 is large enough to allow a pipe or line to pass through smoothly. A central angle less than 180° ensures that the circumferential length of the main body 100 is not less than the circumferential length of the cover 200, allowing the cover 200 to slide on the main body 100. Furthermore, the central angle of the cover 200 is substantially the same as that of the avoidance opening 140, and thus the central angle of the cover 200 does not exceed 270°. When the cover 200 is opened, a sufficiently large avoidance opening 140 is exposed.

[0058] In practical applications, the central angle corresponding to the avoidance opening 140 can be determined according to the diameter of the pipeline or line. For example, the central angle corresponding to the avoidance opening 140 can be 100° or 120°.

[0059] In order to increase the friction between the cover body 200 and the main body 100, the side surface of the main body 100 facing the cover body 200 may be provided with an area with greater roughness. This embodiment defines this area as a rough area. Exemplarily, a part of the side surface of the main body 100 facing the cover body 200 is the rough area, and the rough area is arranged close to the avoidance opening 140; or, the rough area covers the entire area of the side surface of the main body 100 facing the cover body 200, and this side surface of the main body 100 is a rough surface to prevent the cover body 200 from automatically opening due to factors such as gravity after it is closed.

[0060] Exemplarily, the side surface of the cover body 200 facing the main body 100 may also be provided with a rough area, and the rough area is provided near both ends of the cover body 200; or, the rough area covers the entire area of the side surface of the cover body 200 facing the main body 100, and the side surface of the cover body 200 is a rough surface to prevent the cover body 200 from automatically opening due to factors such as gravity after being closed.

[0061] Figure 5 This is a cross-sectional diagram of the wall penetration sheath provided in Example 1 of the present application. Figure 1 and Figure 5 As shown, the cover 200 can be slidably connected to the side of the main body 100 facing away from the wall.

[0062] It is understandable that at this time, the abutment portion 150 can protrude outward from the surface of the main body 100, that is, the abutment portion 150 can protrude toward the side of the main body 100 away from the wall, so that the end of the cover body 200 can abut against the abutment portion 150.

[0063] Exemplarily, the cover body 200 may include a main cover portion 210, an inner wall portion 220, and an outer wall portion 230. The inner wall portion 220 and the outer wall portion 230 are respectively connected to the radial inner side edge and the radial outer side edge of the main cover portion 210, the inner wall portion 220 contacts the surface of the inner plate portion 120 facing away from the main plate portion 110, and the outer wall portion 230 contacts the surface of the outer plate portion 130 facing away from the main plate portion 110, and the ends of the inner wall portion 220 and the outer wall portion 230 away from the main cover portion 210 each have a flange 240, which is folded toward the side where the main cover portion 210 is located.

[0064] In this way, the flange 240 of the cover body 200 and the main cover plate portion 210 can be Figure 5 The upper and lower directions shown in the figure limit the relative position of the main body 100 and itself, and the inner wall portion 220 and the outer wall portion 230 of the cover body 200 can be Figure 5The left and right directions shown limit the relative position of the main body 100 and itself, and the cover body 200 can slide along the circumference of the main body 100 to achieve a sliding connection between the cover body 200 and the main body 100.

[0065] like Figure 5 As shown, in some examples, the flange 240 can be horizontally flipped toward the inner plate portion 120 (ie, inward) to achieve upper and lower limits on the relative positions of the main body 100 and the cover body 200.

[0066] In other examples, the flange 240 may include a horizontal portion and a vertical portion (not shown), wherein the horizontal portion is folded toward the inner plate portion 120 (i.e., inward), and the vertical portion is folded toward the main plate portion 110 (i.e., downward). In this way, the flange 240 can also achieve left and right limiting of the relative position of the main body 100 and the cover body 200, thereby improving the stability of the connection between the main body 100 and the cover body 200.

[0067] Furthermore, when the inner diameter of the wall hole is slightly smaller than the diameter of the annular structure formed by the inner plate portion 120 of the main body 100 and the inner wall portion 220 of the cover 200, because the end faces of the inner plate portion 120 and the inner wall portion 220 do not abut, the inner plate portion 120 of the main body 100 and the inner wall portion 220 of the cover 200 can retract inward to fit the wall hole. This can also increase the friction between the wall sheath and the inner wall surface of the wall hole, preventing the wall sheath from falling out of the wall hole. Thus, the wall sheath provided in this embodiment has wide adaptability and high stability.

[0068] In addition, in order to further increase the adaptability of the wall-penetrating sheath, multiple notches (not shown in the figure) can be spaced apart on the inner plate portion 120 of the main body 100 and the inner wall portion 220 of the cover body 200 along the circumference of the wall-penetrating sheath to increase the inward contraction range of the inner plate portion 120 of the main body 100 and the inner wall portion 220 of the cover body 200.

[0069] Example 2

[0070] Figure 6 This is a cross-sectional diagram of a wall-penetrating sheath provided in Example 2 of this application. Figure 6 As shown, similar to the wall-penetrating sheath provided in Example 1, the wall-penetrating sheath provided in this embodiment also includes a main body 100 and a cover body 200, wherein an avoidance opening 140 is also provided on the main body 100, and the cover body 200 is also slidably connected to the main body 100. The difference is that the cover body 200 of this embodiment can be slidably connected to the side of the main body 100 facing the wall.

[0071] Similar to the first embodiment, the cover body 200 may include a main cover plate portion 210, an inner wall portion 220, and an outer wall portion 230. The inner wall portion 220 and the outer wall portion 230 are respectively connected to the inner side edge and the outer side edge of the main cover plate portion 210 in the radial direction, the inner wall portion 220 contacts the surface of the side of the inner plate portion 120 facing the main plate portion 110, and the outer wall portion 230 contacts the surface of the side of the outer plate portion 130 facing the main plate portion 110, and matching limiting structures are provided between the inner wall portion 220 and the inner plate portion 120 and between the outer wall portion 230 and the outer plate portion 130. The limiting structure can be Figure 6 The upper and lower directions and the left and right directions shown limit the relative positions of the main body 100 and the cover body 200 so that the cover body 200 slides along the circumference of the main body 100 .

[0072] In some examples, the limiting structure may include a stop wall 160, which extends out from the opposite side wall surfaces of the inner plate portion 120 and the outer plate portion 130, and the end of the inner wall portion 220 away from the main cover portion 210 and the end of the outer wall portion 230 away from the main cover portion 210 respectively abut against the corresponding stop wall 160.

[0073] In this way, the stop wall 160 of the main body 100 and the main board portion 110 can be Figure 6 The relative position of the cover 200 and itself is limited in the up and down directions shown in the figure. The inner plate portion 120 and the outer plate portion 130 of the main body 100 can be Figure 6 The left and right directions shown limit the relative position of the cover body 200 and itself, and the cover body 200 can slide along the circumference of the main body 100 to achieve a sliding connection between the cover body 200 and the main body 100.

[0074] In other examples, the limiting structure may include a sliding groove 320 and a sliding bar 310 .

[0075] Figure 7 This is a cross-sectional diagram of another wall-penetrating sheath provided in Example 2 of this application. Figure 7 As shown, the slide groove 320 can be set on the main body 100, and the slide bar 310 can be set on the cover body 200. Specifically, the slide groove 320 can be set on the opposite side wall surfaces of the inner plate portion 120 and the outer plate portion 130, and the slide bar 310 can extend out from the side surface of the inner wall portion 220 facing away from the main cover portion 210 and the side surface of the outer wall portion 230 facing away from the main cover portion 210, and the slide bar 310 slides along the slide groove 320.

[0076] Figure 8 This is a cross-sectional diagram of the third wall penetration sheath provided in Example 2 of this application. Figure 8As shown, the slide bar 310 can be set on the main body 100, and the slide groove 320 can be set on the cover body 200. Specifically, the slide bar 310 can extend out from the opposite side wall of the inner plate portion 120 and the outer plate portion 130, and the slide groove 320 can be set on the opposite side surface of the inner wall portion 220 and the outer wall portion 230, and the slide bar 310 slides along the slide groove 320.

[0077] In this way, the sliding groove 320 of the cover 200 and the sliding bar 310 of the main body 100 cooperate with each other. Figure 6 The upper and lower directions and the left and right directions shown limit the relative positions of the cover body 200 and the main body 100 , and the cover body 200 can slide along the circumference of the main body 100 to achieve a sliding connection between the cover body 200 and the main body 100 .

[0078] The main body 100 of this embodiment may also be provided with an abutment portion 150, which is located in the middle area of the main body 100 in the circumferential direction. The abutment portion 150 protrudes from the surface of the main body 100, and the circumferential ends of the abutment portion 150 are used to abut the corresponding ends of the cover body 200. Providing the abutment portion 150 can simplify the operation and improve the installation efficiency.

[0079] The protruding direction of the abutting portion 150 can be set according to the position of the cover 200. In this embodiment, the cover 200 is slidably connected to the side of the main body 100 facing the wall, and the abutting portion 150 can protrude inwardly from the surface of the main body 100, that is, the abutting portion 150 can protrude toward the side of the main body 100 facing the wall.

[0080] For example, the chute 320 may be Figure 7 The opening slot shown, the slide slot 320 can also be as follows Figure 8 When the chute 320 is an open chute, the main body or cover where the chute 320 is located has good flatness, and the chute 320 can extend from the end to the middle of the main body or cover in the circumferential direction, ensuring that the physical structures on both sides of the chute 320 can be connected together; when the chute 320 is a closed chute, the main body or cover where the chute 320 is located has good structural strength, and the chute 320 can extend from one end to the other end of the main body or cover in the circumferential direction.

[0081] In addition, other structures and functions of the wall penetration sheath are introduced in detail in the first embodiment and will not be repeated here.

[0082] It should be understood that the structures illustrated in the embodiments of this application do not constitute specific limitations on the wall sheath. In other embodiments of this application, the wall sheath may include more or fewer components than shown, or may combine or separate certain components, or have different component arrangements.
