Description

Technical Field

[0001] The utility model relates to the field of doors and windows, in particular to a gap-covered inner-hidden door leaf type aluminum-clad wood lifting and sliding door. Background Art

[0002] There are many types of sliding doors on the market, mainly aluminum-magnesium alloy sliding doors, titanium-magnesium alloy sliding doors, wooden sliding doors, carbon steel sliding doors and plastic steel sliding doors. The main component of aluminum-magnesium alloy sliding doors is aluminum. The addition of magnesium improves its strength to a certain extent. The main feature of this kind of sliding door is that it is made of metal, which makes it have good thermal conductivity. The strength is also improved a lot because of the alloy. In addition, the appearance of aluminum-magnesium alloy is silvery white, which is very visually impactful, beautiful and clean. The disadvantage is that the hardness is not enough, and the current market price is still very expensive.

[0003] Titanium-magnesium alloy sliding doors have better performance in all aspects than aluminum-magnesium alloy sliding doors. On the basis of titanium and magnesium, carbon fiber materials are added to make the strength and hardness of titanium-magnesium alloy reach the standards we require, and the thermal conductivity is also better than aluminum-magnesium alloy. Due to these excellent properties of titanium-magnesium alloy materials, titanium-magnesium alloy sliding doors are widely promoted and applied in various sliding doors, and are favored by many owners.

[0004] Wooden sliding doors are mainly made of solid wood, and artificial wood boards cannot meet the standards under the current technological level. Wooden sliding doors are also the most common type of sliding doors we see in daily life, and the performance of wooden sliding doors is relatively ordinary.

[0005] The advantages of plastic steel sliding door are energy saving, flame retardant, beautiful, corrosion resistant, long service life, sound insulation, and it is also of great significance to protect wood and ecological environment, and has been unanimously recognized by the society. Due to its good sealing and heat insulation, overall non-deformation, and surface aging, it is particularly suitable for the northern region with strong winds and sand, and is an excellent choice among various sliding doors. Moreover, for residences with high outdoor noise, hollow or double-layer hollow glass can be selected, which has excellent sealing and sound insulation effects.

[0006] Among them, the aluminum-clad wood lifting and sliding door is a kind of aluminum-magnesium alloy sliding door. The existing aluminum-clad wood lifting and sliding door has the following problems in long-term use:

[0007] 1. In order to ensure that there is enough space for pushing and pulling the door leaf after it is lifted, a 12mm gap is usually left between the upper side of the door leaf and the upper frame (see Figure 1 ), due to the existence of gaps, the sealing performance is poor.

[0008] 2. The vertical side sash and vertical frame generally adopt the contact seal. This sealing method will be not tightly sealed after long-term use (see Figure 2 ), reducing the effect of thermal insulation. Utility Model Content

[0009] The utility model aims to provide an aluminum-clad wood lifting and sliding door with a hidden door leaf and good sealing effect, so as to solve the above-mentioned problems existing in the prior art.

[0010] In order to achieve the above-mentioned purpose, the utility model provides a kind of aluminum-clad wood lifting and sliding door with concealed door leaf, which includes four frames, namely an upper frame, a lower frame, a left frame and a right frame. A plurality of door leaves are arranged in the area between the upper frame, the lower frame, the left frame and the right frame. A hollow glass is arranged in the middle of the door leaf. The upper frame and the left frame are both L-shaped. The upper end of the door leaf is covered on the inner side of the upper frame. The left leaf of the open leaf among the plurality of door leaves is covered on the inner side of the left frame. Sealing strips are arranged between the upper frame and the upper end of the open leaf and between the left frame and the left leaf. The lower frame is formed by composite covering of an aluminum door sill and a wood profile.

[0011] Furthermore, the sealing strip is an EPDM strip.

[0012] Furthermore, a push-pull handle is installed on the door sash.

[0013] Furthermore, the push-pull handle is installed in the middle of the right side wall of the right side sash of the opened sash.

[0014] Furthermore, one side of the lower frame located indoors is a decorative surface of a wooden profile.

[0015] Furthermore, a sealing strip provided between the upper frame and the upper end of the sash is located between the vertical frame of the upper frame and the upper end of the sash, and the sealing strip is fixed on the vertical frame of the upper frame.

[0016] Furthermore, the sealing strip provided between the left frame and the left fan is located between the front frame of the left frame and the left fan, and the sealing strip is fixed on the front frame of the left frame.

[0017] Furthermore, the width of the frame and the door leaf is 25-35 mm.

[0018] In summary, the technical solution of the utility model has the following beneficial effects:

[0019] 1. Wrap the upper end of the door leaf on the inner side of the upper frame so that the upper end of the door leaf is completely hidden inside the upper frame, so that the gap between the upper frame and the door leaf can be completely covered; wrap the left leaf of the open door leaf on the inner side of the left frame so that the gap between the left frame and the open door leaf can be completely covered, thus realizing a stable and concealed sealing connection process between the sliding door frame and the leaf overlap.

[0020] 2. Sealing strips are provided between the upper frame and the upper end of the open door, as well as between the left frame and the left door. The location of the sealing strips is reasonable and necessary. The sealing strips are made of EPDM strips, which are weather-resistant and high-temperature resistant and can adapt to various environments, thereby improving the overall sealing performance of the sliding door.

[0021] 3. Install the push-pull handle in the middle of the right side of the open door leaf to meet the design requirements of the frame covering the door leaf.

[0022] 4. The width of the frame and the door leaf is 25-35mm, which reduces the width of the frame and the door leaf, increases the overall lighting area of ​​the sliding door, and has a good lighting effect, solving the problem of traditional sliding doors affecting lighting due to the wide frame and leaf width.

[0023] 5. The lower frame is designed as a composite threshold of aluminum and wood profiles, which ensures the threshold's water resistance and wear resistance. The decorative surface of the lower frame on the indoor side is a wooden profile decorative surface, making the indoor appearance of the sliding door more simple and beautiful.

[0024] 6. The sliding door of the utility model can only see the frame of the sliding door indoors. The sliding door has a simpler appearance and a simpler overall structure. It realizes a structural form of hidden door leaves, has a stable and uniform sealing effect, and has a lighting area that meets the requirements of the specifications.
