Description

Technical Field

[0001] This application relates to the field of air conditioning pipe fittings technology, and in particular to an air conditioning hole sleeve. Background Technology

[0002] During air conditioner installation, the indoor and outdoor units need to be connected through air conditioning pipes, therefore, air conditioning holes are required in the wall to allow these pipes to pass through. Typically, the air conditioning pipe sleeves are pre-embedded before the wall is poured, thus creating the air conditioning holes in the poured wall. Afterwards, plastering is required on both the interior and exterior walls, forming an outer plaster layer on the exterior wall and an inner plaster layer on the interior wall. Additionally, insulation boards for the interior and exterior walls need to be installed in different locations.

[0003] An external wall air conditioning pipe sleeve, with announcement number CN215950614U, includes an air conditioning sleeve comprising an upper horizontal sleeve, a lower horizontal sleeve, and an inclined section sleeve. Both the upper and lower horizontal sleeves are connected to the inclined section sleeve. During pre-installation, the lower horizontal sleeve faces outwards from the wall, while the upper horizontal sleeve faces inwards from the wall, and the height of the lower horizontal sleeve is less than the height of the upper horizontal sleeve. This design prevents rainwater from easily entering the room through the inclined section sleeve during rainy weather.

[0004] Regarding the aforementioned technologies, there is still a possibility that rainwater may seep into the room through the joint between the air conditioner sleeve and the air conditioner hole during heavy rain. Utility Model Content

[0005] In order to reduce the probability of rainwater seeping into the room from the joint between the air conditioner sleeve and the air conditioner hole, this application provides an air conditioner sleeve.

[0006] The technical solution for an air conditioning duct sleeve provided in this application is as follows:

[0007] An air conditioning duct sleeve includes an air conditioning sleeve, an outer mounting sleeve disposed at the outdoor end of the air conditioning sleeve, an inner mounting sleeve disposed at the indoor end of the air conditioning sleeve, an outer mounting cover detachably mounted on the outer mounting sleeve, and an inner mounting cover detachably mounted on the inner mounting sleeve; the outer mounting sleeve has an outer insert ring for fitting against the outer wall surface of the cast-in-place wall, and the inner mounting sleeve has an inner insert ring for fitting against the inner wall surface of the cast-in-place wall.

[0008] By adopting the above technical solution, the air conditioning sleeve, outer mounting sleeve, and inner mounting sleeve are pre-embedded before the concrete is poured. This ensures that after the concrete is poured, the outer ring in the outer mounting sleeve fits snugly against the outer wall of the concrete, and the inner ring in the inner mounting sleeve fits snugly against the inner wall of the concrete. When plastering the inner and outer walls, the outer plaster layer covers the outer ring, and the inner plaster layer covers the inner ring. The outer mounting cover is installed on the outer mounting sleeve, and the inner mounting cover is installed on the inner mounting sleeve. Because the outer plaster layer covers the outer ring and the inner plaster layer covers the inner ring, the probability of rainwater seeping into the room through the outer plaster layer and bypassing the outer ring during heavy rain is low.

[0009] Optionally, the air conditioning sleeve includes an inclined sleeve, an upper sleeve disposed in the inclined sleeve facing the outside, and a lower sleeve disposed in the inclined sleeve facing the inside; the upper sleeve and the lower sleeve are both arranged horizontally, and the inclined sleeve is arranged inclined downward from the inside to the outside.

[0010] By adopting the above technical solution, the specific structure of the air conditioning sleeve is disclosed. The inclined sleeve is arranged at an upward angle from the indoor to the outdoor, which makes it difficult for rainwater to flow into the room from the inclined sleeve.

[0011] Optionally, the inner mounting sleeve has an inner retaining ring radially inward at the end facing the outside, and the inner diameter of the inner retaining ring is adapted to the outer diameter of the air conditioning pipeline.

[0012] By adopting the above technical solution, the inner wall of the inner clamping ring can fit snugly against the air conditioning pipes during installation, which helps to reduce the probability of rainwater drifting into the room along the air conditioning sleeve.

[0013] Optionally, the external mounting sleeve has an external snap-fit ​​ring radially inward at the end facing the room, and the inner diameter of the external snap-fit ​​ring is adapted to the outer diameter of the air conditioning pipeline.

[0014] By adopting the above technical solution, the inner wall of the outer clamping ring can fit snugly against the air conditioning pipes during installation, which helps to reduce the probability of rainwater drifting into the air conditioning sleeve from the outside.

[0015] Optionally, the outer snap ring has an outer guide ring surface that is radially inward and inclined at the end facing the interior.

[0016] By adopting the above technical solution, the setting of the outer guide ring makes it easier for the air conditioning pipeline to pass through the outer clamping ring to the outside.

[0017] Optionally, the outer clamping ring has an outer rubber sheet at the end furthest from the room, and the outer rubber sheet has an outer rubber through hole for the air conditioning pipeline to pass through.

[0018] By adopting the above technical solution, when the air conditioning pipes pass through the outer rubber through-hole of the outer rubber sheet, the elasticity of the rubber sheet allows it to fit snugly against the air conditioning pipes. The outer rubber sheet further reduces the probability of rainwater entering the room through the air conditioning sleeve.

[0019] Optionally, when the outer mounting cover is installed on the outer mounting sleeve, the end of the outer mounting cover facing the interior abuts against the outer rubber sheet.

[0020] By adopting the above technical solution, the outer mounting cover abuts against the outer rubber sheet, resulting in fewer gaps at the contact surface between the outer mounting sleeve and the outer snap ring, which helps to reduce the probability of rainwater seeping in from the contact surface between the outer mounting sleeve and the outer snap ring.

[0021] Optionally, the outer mounting cover includes an outer mounting portion that is threadedly engaged with the outer mounting sleeve and an outer mounting ring that connects to the outer mounting portion and extends radially outward, the outer mounting ring being fitted to the outer paint layer.

[0022] By adopting the above technical solution, the specific structure of the outer mounting cover is disclosed. When the outer mounting part is threaded onto the outer mounting sleeve, the outer mounting ring can abut against the outer plaster layer, making it difficult for rainwater to seep in from the contact surface between the outer mounting ring and the outer plaster layer.

[0023] Optionally, the outer mounting ring has a sealing ring on the side facing the interior for contacting the outer paint layer.

[0024] By adopting the above technical solution, the sealing ring is designed so that when the outer mounting cover is threaded onto the outer mounting sleeve, the outer mounting ring can abut against the outer plaster layer, further reducing the probability of rainwater seeping in from between the outer mounting ring and the outer plaster layer.

[0025] Optionally, the outer mounting cover is provided with a guide section facing outward and inclined downward at the bottom connection between the outer mounting part and the outer mounting ring.

[0026] By adopting the above technical solution, the setting of the guide section allows rainwater located at the outer mounting cover to flow outward along the guide section, reducing the probability of rainwater accumulating at the outer mounting cover.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. An air conditioning pipe sleeve, wherein an outer mounting sleeve is installed at the outdoor end of the air conditioning pipe and an inner mounting sleeve is installed at the indoor end of the air conditioning pipe, wherein the outer ring in the outer mounting sleeve can fit against the outer wall surface of the cast wall, and the inner ring in the inner mounting sleeve can fit against the inner wall surface of the cast wall, wherein after the inner and outer walls of the cast wall are plastered, the inner plaster layer can cover the inner ring and the outer plaster layer can cover the outer ring, so that rainwater is not easily seeped into the room;

[0029] 2. By setting an outer rubber sheet on the outer clamping ring, when the air conditioning pipe passes through the outer rubber through hole, the outer rubber sheet can fit with the air conditioning pipe, making it difficult for rainwater to drift into the room along the air conditioning sleeve;

[0030] 3. By setting a sealing ring on the outer mounting ring, rainwater is less likely to seep in between the outer mounting ring and the outer plaster layer. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0039] This application discloses an air conditioning hole sleeve.

[0040] Reference Figure 1 The air conditioning duct sleeve includes an air conditioning sleeve 1 installed in the air conditioning hole, an inner mounting sleeve 2 installed in the air conditioning duct sleeve facing the outside, an outer mounting sleeve 3 installed in the air conditioning duct sleeve facing the inside, an inner mounting cover 4 detachably installed in the inner mounting sleeve 2, and an outer mounting cover 5 detachably installed in the outer mounting sleeve 3.

[0041] Reference Figure 1 The air conditioning sleeve 1 includes an inclined sleeve 11, an upper sleeve 12 connecting the indoor end of the inclined sleeve 11, and a lower sleeve 13 connecting the outdoor end of the inclined sleeve 11. The upper sleeve 12, the inclined sleeve 11, and the lower sleeve 13 are all circular PVC pipes and are integrally installed. The upper sleeve 12 and the lower sleeve 13 are arranged horizontally, while the inclined sleeve 11 is inclined downwards from the indoor to the outdoor direction.

[0042] Reference Figure 2 and Figure 3 The inner mounting sleeve 2 includes an inner mounting tube 21 threaded onto the inner wall of the upper sleeve 12, an inner ring 22 extending radially outward from the inner mounting tube 21 towards the indoor side, and an inner snap-fit ​​ring 23 arranged radially inward from the inner mounting tube 21 towards the outdoor side. The inner mounting tube 21, the inner ring 22, and the inner snap-fit ​​ring 23 are integrally formed and are all made of PVC material. The inner ring 22 is fitted against the inner wall of the cast-in-place wall on the outdoor side, allowing the inner plaster layer to cover the inner ring 22 when the inner wall is plastered.

[0043] Reference Figure 1 and Figure 2 The inner diameter of the inner retaining ring 23 is adapted to the outer diameter of the through-hole pipeline, so that when the air conditioning pipeline passes through the inner retaining ring 23, the inner wall of the inner retaining ring 23 can fit against the outer wall of the air conditioning pipeline. To facilitate the passage of the air conditioning pipeline through the inner retaining ring 23, the inner retaining ring 23 has a radially inward and inclined inner guide ring surface 231 at the end facing the room. When the air conditioning pipeline is inserted from the room into the inner retaining ring 23, the end of the air conditioning pipeline can pass through the central through-hole of the inner retaining ring 23 under the guidance of the inner guide ring surface 231.

[0044] Reference Figure 2 and Figure 4 The inner mounting cover 4 includes an inner mounting portion 41 threaded onto the inner wall of the inner mounting tube 21, and an inner mounting ring 42 connected to the inner mounting portion 41 near the interior end and extending radially outward. The inner mounting ring 42 is in contact with the inner plaster layer.

[0045] Reference Figure 2 and Figure 5The outer mounting sleeve 3 includes an outer mounting tube 31 threaded onto the inner wall of the lower sleeve 13, an outer embedded ring 32 connected to the outer mounting tube 31 facing outwards and extending radially outwards, and an outer snap-fit ​​ring 33 disposed in the outer mounting tube 31 facing inwards and arranged radially inwards. The outer mounting tube 31, the outer embedded ring 32, and the outer snap-fit ​​ring 33 are integrally formed, and all three are made of PVC material. The outer embedded ring 32 is fitted against the outer wall of the cast-in-place wall on the side facing inwards, allowing the outer plaster layer to cover the outer embedded ring 32 during exterior wall painting.

[0046] Reference Figure 2 and Figure 5 The inner diameter of the outer clamping ring 33 is adapted to the outer diameter of the air conditioning pipe, allowing the air conditioning pipe to fit snugly against the inner wall of the outer clamping ring 33 when it passes through. To facilitate the passage of the air conditioning pipe through the outer clamping ring 33, the outer clamping ring 33 has a radially inwardly arranged and inclined outer guide ring surface 331 at the end facing the room. When the air conditioning pipe is inserted from the inner clamping ring 23 into the outer clamping ring 33, the end of the air conditioning pipe can pass through the central through hole of the outer clamping ring 33 under the guidance of the outer guide ring surface 331.

[0047] Reference Figure 2 The outer clamping ring 33 also has an outer rubber sheet 6 on the side facing the outside. The outer rubber sheet 6 is glued to the outer clamping ring 33. The outer rubber sheet 6 has an outer rubber through hole 61 at its center. The diameter of the outer rubber through hole 61 is 85% of the diameter of the central through hole of the outer clamping ring 33. Because the rubber sheet is elastic, the outer rubber sheet 6 can fit tightly with the air conditioning pipe after passing through the outer rubber through hole 61.

[0048] Reference Figure 2 and Figure 6 The outer mounting cover 5 includes an outer mounting portion 51 threaded onto the inner wall of the outer mounting tube 31, and an outer mounting ring 52 extending radially outward from the outer mounting portion 51 at its outdoor end. The outer mounting portion 51 and the outer mounting ring 52 are integrally formed. When the outer mounting cover 5 is threaded onto the outer mounting tube 31, the indoor-facing end of the outer mounting ring 52 can abut against the outer plaster layer, and the indoor-facing end of the outer mounting portion 51 can abut against the outer rubber sheet 6 provided on the outer snap ring 33. This results in a good seal between the outer mounting cover 5 and the outer mounting sleeve 3, preventing rainwater from easily flowing into the gap between the outer mounting cover 5 and the outer mounting sleeve 3.

[0049] Reference Figure 2The outer mounting ring 52 has a sealing ring 7 glued to the side facing the outer paint layer. During the process of threading the outer mounting cover 5 onto the outer mounting sleeve 3, the outer mounting ring 52 can gradually squeeze the sealing ring 7, so that the sealing ring 7 is tightly fitted with the outer mounting ring 52 and the outer paint layer, thereby reducing the probability of rainwater seeping in from the contact surface between the outer mounting ring 52 and the outer paint layer.

[0050] Reference Figure 2 and Figure 5 The outer mounting cover 5 has a guide section 53 at the bottom of the connection between the outer mounting part 51 and the outer mounting ring 52, which faces the outside and is arranged at an angle downward, so that rainwater can flow outward along the guide section 53 and is not easy to accumulate at the outer mounting cover 5.

[0051] Combination Figures 1 to 6 The implementation principle of an air conditioning pipe sleeve according to an embodiment of this application is as follows: By installing an inner mounting sleeve 2 and an outer mounting sleeve 3 at both ends of the air conditioning pipe 1, the inner embedded ring can fit against the inner wall surface of the cast wall, and the outer embedded ring 32 can fit against the outer wall surface of the cast wall. After the inner wall surface and the outer wall surface of the cast wall are plastered, the inner plaster layer can cover the inner embedded ring 22, and the outer plaster layer can cover the outer embedded ring 32. Then, an outer mounting cover 5 is also installed on the outer mounting sleeve 3, and a sealing ring 7 is also provided between the outer mounting ring 52 and the outer plaster layer, so that rainwater is not easily seeped between the outer mounting ring 52 and the outer plaster layer, and rainwater is not easily able to seep through the outer plaster layer and bypass the outer embedded ring 32 to seep into the room.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
