Description

Technical Field

[0001] This application relates to the technical field of door and window hardware, and particularly to a lower frame drainage structure. Background Art

[0002] For outdoor sliding doors, a drainage structure is usually required to prevent rainwater or accumulated water from accumulating at the lower part of the door frame. The existing sliding door drainage system usually sets a drainage bottom frame on the side of the bottom frame of the door frame facing the outdoors, and then opens drainage openings on the drainage bottom frame. Some drainage openings of the drainage bottom frame are opened on-site, and the area of the drainage openings is usually large. The large-area openings may cause the structural strength of the bottom frame to weaken. During the processing, especially for materials such as aluminum alloy, problems such as local warping and deformation are likely to occur due to stress release. After processing, the stability of the overall component may also be affected to a certain extent. Utility Model Content

[0003] In order to achieve the drainage function while reducing the impact on the structural strength of the drainage bottom frame and reducing the deformation of the drainage bottom frame, this application provides a lower frame drainage structure.

[0004] The lower frame drainage structure provided by this application adopts the following technical solutions:

[0005] A lower frame drainage structure includes a drainage base and a casting. The casting is provided with a drainage opening, and a drainage groove is arranged inside the casting. The drainage groove penetrates to one end of the casting facing the drainage base. The casting is installed at one end of the drainage base, and the casting and the drainage base together form a drainage bottom frame.

[0006] By adopting the above technical solutions, the casting is integrally formed by die-casting, and there is no need to perform secondary hole opening on the drainage bottom frame, avoiding the problem of weakening the strength of the bottom frame due to the excessive area of the drainage opening in the traditional method.

[0007] Optionally, the drainage base includes a profile, and the profile is in an "L" shape. The high side part of the vertical side of the profile is the side of the profile away from the sliding door frame, and the low side part of the vertical side of the profile is the side of the profile close to the sliding door frame. The low side part of the vertical side of the profile is connected to the sliding door frame through a heat insulation strip.

[0008] By adopting the above technical solutions, such a structural design of the profile can reasonably utilize the space above the heat insulation strip. In the same occupied space, this design can form a larger drainage area and is also beneficial to reducing the weight of the profile.

[0009] Optionally, the casting is a die-casting part, and the end face of the casting facing the profile is provided with a plug-in part, a bottom abutting part and a side abutting part;

[0010] When the casting is spliced ​​with the profile, the bottom abutment part is located below the bottom of the profile and contacts the bottom surface of the profile. The insertion part is inserted into the space enclosed by the lower side section of the vertical side of the profile, the heat insulation strip and the sliding door frame. The side abutment part contacts the inner side surface of the higher side section of the vertical side of the profile.

[0011] By adopting the above technical solution, the interlocking part cleverly utilizes the space between the thermal insulation strip and the sliding door frame. The cooperation of the interlocking part, the bottom abutment part, and the side abutment part enables quick positioning and connection between the casting and the end of the profile, facilitating installation and disassembly. Furthermore, the bottom abutment part contacts the bottom of the profile, ensuring a stable connection between the casting and the profile in the vertical direction. The side abutment part contacts the inner surface of the higher side of the profile, further enhancing the lateral stability of the casting and improving the overall structural strength and durability.

[0012] Optionally, a connecting hole is provided on the lower side of the vertical side of the profile, the connecting hole extending to both ends of the profile and the inner surface of the lower side of the vertical side of the profile, and the casting is connected to the profile by self-tapping screws.

[0013] By adopting the above technical solution, direct drilling is inconvenient due to the long length of the profile, especially for machining with high precision requirements. By opening the connecting hole on the lower inner side of the vertical side of the profile, machining can be performed directly from the inside, improving processing efficiency while ensuring drilling accuracy. Furthermore, the use of self-tapping screws eliminates the need for pre-machining threads in the connecting hole, ensuring a secure connection.

[0014] Optionally, the inner side of the casting is provided with a first stiffening part, a second stiffening part and a mounting part. The two ends of the first stiffening part are respectively connected to the insertion part and the mounting part. The mounting part has a mounting hole that is directly opposite to the connection hole. The second stiffening part is connected to the side abutment part. The drain outlet extends through to the second stiffening part.

[0015] By adopting the above technical solution, the first stiffening part and the second stiffening part enhance the lateral compressive strength of the casting and improve the overall structural strength of the casting.

[0016] Optionally, the drainage base further includes a drainage grid, which is supported within the profile, and the top surface of the drainage grid is flush with the top surface of the profile and the top surface of the casting, and the drainage grid covers the top of the profile and the top of the casting.

[0017] By adopting the above technical solution, the top surface of the drainage grille is flush with the top surfaces of the profile and the casting, mainly aiming to avoid protrusions, which can effectively prevent pedestrians from tripping when walking near the sliding door. The support design of the drainage grille can be easily snapped into or removed from the interior of the profile, thus improving the convenience of installation and maintenance.

[0018] Optionally, a support protrusion is provided on the inner surface of the high-side portion of the vertical side of the profile. The drainage grille is in an inverted "L" shape. The low-side portion of the vertical side of the drainage grille is supported on the support protrusion, and the high-side portion of the vertical side of the drainage grille is supported on the sliding door frame and is arranged in contact with the outer side wall of the sliding door frame.

[0019] By adopting the above technical solution, a support protrusion is provided on the inner surface of the high-side portion of the vertical side of the profile. The low-side portion of the drainage grille is supported on this support protrusion, and the high-side portion of the drainage grille is in contact with the sliding door frame. This design配合 with the "L" shape of the profile ensures a larger drainage space.

[0020] Optionally, multiple drainage grooves are provided at the top of the drainage grille. The drainage grooves are arranged along the length direction of the drainage grille. The drainage outlet of the drainage grille is connected to the drainage grooves, and the width of the top of the drainage groove is smaller than the width of the bottom of the drainage groove.

[0021] By adopting the above technical solution, due to the existence of the drainage grooves, the water flow will not directly cover the entire surface of the drainage grille. When the precipitation is large or there is accumulated water, the water can flow along the drainage grooves and it is not easy to form a stagnant water surface. Moreover, the design that the width of the top of the drainage groove is smaller than the width of the bottom of the drainage groove can play a role in filtering large-particle debris. Debris (such as leaves, soil, etc.) is more likely to be blocked outside the drainage grooves in the water flow, thus avoiding directly entering the drainage channel and blocking the drainage grille.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The casting is integrally formed by die-casting, without the need for secondary hole opening on the drainage bottom frame, avoiding the problem of weakening the strength of the bottom frame due to the excessive area of the drainage opening in the traditional method. While achieving the drainage function, it reduces the impact on the structural strength of the drainage bottom frame and reduces the situation of deformation of the drainage bottom frame;

[0024] 2. The "L" shape structural design of the profile can reasonably utilize the space above the heat insulation strip. In the same occupied space, this design can form a larger drainage area and is also beneficial to reducing the weight of the profile;

[0025] 3. The interlocking part cleverly utilizes the space between the heat insulation strip and the sliding door frame. The cooperation of the interlocking part, the bottom abutment part and the side abutment part can realize the quick positioning and connection between the casting and the end of the profile, which is convenient for installation and disassembly.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a lower frame drainage structure.

[0033] like Figure 1 The lower frame drainage structure includes a drainage base 1 and a casting 2;

[0034] like Figure 2 and Figure 3 In this embodiment, the casting 2 is a die casting. In other embodiments, the casting 2 can also be a sand casting / gravity casting, etc. The casting 2 has a drainage groove 21 inside, which extends to one end and the top of the casting 2. The drainage groove 21 also extends to the top of the casting 2 facing indoors. A drain pipe 22 is integrally formed on the outdoor side of the casting 2. The casting 2 has a drain outlet 23 that communicates with the drain pipe 22 and is connected to the drainage groove 21.

[0035] On the end face of the casting 2 facing the indoor side, an insertion part 24 extends out. On the protruding part of the insertion part 24 facing the outdoor side, a first stiffening part 25 is integrally formed. The first stiffening part 25 extends along the length direction of the inner side wall of the casting 2. An installation part 26 is integrally formed on the first stiffening part 25. The installation part 26 is perpendicular to the first stiffening part 25. The installation part 26 is integrally formed on the inner end face of the casting 2. An installation hole 27 penetrating through the casting 2 is provided in the installation part 26.

[0036] On the end face of the casting 2 facing the outdoor side, a side contact part 28 extends out. On the side of the side contact part 28 facing the indoor side, a second stiffening part 29 is integrally formed. The second stiffening part 29 extends along the length direction of the inner side wall of the casting 2. And the drain port 23 penetrates through to the second stiffening part 29.

[0037] On the end face of the bottom of the casting 2 far from the installation part 26, a bottom contact part 210 extends out. The bottom contact part 210 is flush with the bottom surface of the casting 2.

[0038] As Figure 4 , the drain base 1 includes a profile 11. The profile 11 is in an "L" shape. The high side part of the vertical side of the profile 11 (i.e., the part with a longer length of the profile 11) is the side of the profile 11 far from the sliding door frame (i.e., the side of the profile 11 facing the outdoor side). The low side part of the vertical side of the profile 11 (i.e., the part with a shorter length of the profile 11) is the side of the profile 11 close to the sliding door frame (i.e., the side of the profile 11 facing the indoor side). The low side part of the vertical side of the profile 11 is connected to the bottom frame of the sliding door through two heat insulation strips 3.

[0039] On the inner side wall of the high side part of the vertical side of the profile 11, a support protrusion 111 extends out. On the low side of the vertical side of the profile 11, a connection hole 112 is provided. The connection hole 112 penetrates through both ends of the profile 11 and the inner side surface of the low side of the vertical side of the profile 11.

[0040] The casting 2 is spliced with the end of the profile 11 through the side contact part 28, the insertion part 24 and the bottom contact part 210. The bottom contact part 210 is located below the bottom of the profile 11 and contacts the bottom surface of the profile 11. The insertion part 24 is inserted into the space surrounded by the low side part of the vertical side of the profile 11, the two heat insulation strips 3 and the outer side wall of the bottom frame of the sliding door. The side contact part 28 contacts the inner side surface of the high side part of the vertical side of the profile 11. The casting 2 is connected to the profile 11 through self-tapping screws (not shown in the figure). The self-tapping screws pass through the installation hole 27 and are threadedly connected in the connection hole 112, so that the casting 2 and the profile 11 are connected to form a drain bottom frame.

[0041] The drainage base 1 further includes a drainage grille 12, which is in an inverted "L" shape. The lower side part of the vertical side of the drainage grille 12 is supported on the support protrusion 111, and the higher side part of the vertical side of the drainage grille 12 is supported on the sliding door frame and is arranged in contact with the outer side wall of the sliding door frame. That is, the drainage grille 12 is supported within the profile 11, and the top surface of the drainage grille 12 is flush with the top surface of the profile 11 and the top surface of the casting 2. Moreover, the drainage grille 12 covers the top of the profile 11 and the top of the casting 2. A plurality of drainage grooves 121 are formed in the top of the drainage grille 12. The drainage grooves 121 are arranged along the length direction of the drainage grille 12. The drainage outlet 23 of the drainage grille 12 is communicated with the drainage grooves 121, and the width of the top of the drainage groove 121 is smaller than the width of the bottom of the drainage groove 121.

[0042] The implementation principle of the embodiment of the present application is as follows: The casting 2 is integrally formed by die-casting, without secondary hole opening on the drainage bottom frame, avoiding the problem of weakening the strength of the bottom frame due to the excessively large area of the drainage outlet 23 in the traditional method. While having the drainage function, it reduces the impact on the structural strength of the drainage bottom frame and reduces the deformation of the drainage bottom frame.

[0043] Moreover, the insertion part 24 makes clever use of the space between the heat insulation strip 3 and the sliding door frame. The cooperation of the insertion part 24, the bottom abutting part 210 and the side abutting part 28 can achieve the rapid positioning connection between the casting 2 and the end of the profile 11, facilitating installation and disassembly.

[0044] The above are all the preferred embodiments of the present application. It does not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
