Description

Technical Field

[0001] This utility model relates to the field of entrance door technology, and in particular to the structure of the visible seam process for entrance doors. Background Technology

[0002] Currently, when installing front doors, a gap is consciously maintained between the door frame and the door, ultimately forming a clear and neat gap line. At the same time, the door leaf and the door frame form a complete plane without any protrusions or indentations. This clean and crisp line perfectly matches the aesthetic pursuit of modern, minimalist, and wabi-sabi styles, bringing a strong sense of order and unity. The entire door looks like a complete flat panel embedded in the wall, weakening the door's presence as an "independent object" and allowing the door to blend better into the wall, making the space look cleaner and more sophisticated.

[0003] The publication CN205936191U, titled "Double-Hook Anti-Pry Exposed Gap Door," points out that when the door panels are closed, gaps exist, and the hinges or locks are located precisely in these gaps. This provides an opportunity for criminals to use tools to pry open the locks or hinges inside the door and enter the house to steal. The proposed solution involves altering the shape of the door frame and door panel joint, causing both edges to bend and extend, thus achieving an anti-theft effect. While the bent joint of the door frame and door panel can create a rubber layer for sealing, the deformation of the rubber layer due to the joint can make it difficult to return to its original position, resulting in gaps when the door is closed. Furthermore, the bent joint makes it easier for dust to accumulate and be difficult to clean. Additionally, any other impurities at the bend can prevent the door panel and frame from fitting together properly. Utility Model Content

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the entrance door surface seam process structure includes a door frame and a door leaf, a connector for opening and closing is provided between the door frame and the door leaf, a cavity for installing the connector is formed on the inward side of the door frame, one side of the door leaf has an integral extension surface for blocking the cavity and forming a surface seam with the door frame, and the other side of the door leaf also forms a surface seam with the door frame. The outer side of the door leaf has a rubber layer for sealing purposes, which is used to press against the door leaf; The connector includes a fixed leaf fixed to the inner wall of the cavity, a movable leaf fixed to the door leaf, and a spindle passing through the fixed leaf and the movable leaf. Both the upper and lower sides of the fixed leaf have a blocking end, which abuts against the movable leaf when the door leaf is closed.

[0006] A further preferred embodiment of this utility model is: one side of the door leaf with an extended surface is flush with one edge of the door frame, and the other side of the door leaf is flush with the other side of the door frame.

[0007] A further preferred embodiment of this utility model is: a baffle is integrally formed on the side surface where the door leaf and the door frame cooperate, and a rubber layer is disposed on the outward side of the baffle and abuts against the baffle.

[0008] A further preferred embodiment of this utility model is: the side of the rubber layer that is in contact with the door leaf is bonded to the door leaf.

[0009] A further preferred embodiment of this utility model is: a second step is provided on the outer side of the door leaf, and a first step is provided on the inner side of the door frame. The first step and the second step are staggered to form a curved passage.

[0010] A further preferred embodiment of this utility model is: the outer end of the rubber layer abuts against the first step, and the outer side of the rubber layer also has an integral fastening end, which fastens to the outer side of the second step.

[0011] A further preferred embodiment of this utility model is: the rubber layer has an integrally protruding end on one side facing inward, the protruding end is attached to the baffle, the inner walls on both sides of the cavity are a longitudinal surface and a transverse surface respectively, there is a gap between the transverse surface and the baffle, and the protruding end is clamped in the gap between the transverse surface and the baffle.

[0012] A further preferred embodiment of this utility model is: the blocking end is fitted with the horizontal surface to fix the position of the blocking end.

[0013] A further preferred embodiment of this utility model is: a connecting shaft extending through the baffle is integrally formed on the inward side of the protruding end, and the end of the connecting shaft is integrally formed with a round end that abuts against the baffle.

[0014] A further preferred embodiment of this utility model is that both the connecting shaft and the round end are made of rubber, for engaging with the baffle.

[0015] Compared with the prior art, the advantages of this utility model are: 1. The door leaf and door frame form a flush and complete plane, retaining clear and neat visible seam lines, which meets the pursuit of modern aesthetics and makes the space look cleaner and more upscale.

[0016] 2. The rubber layer, in conjunction with the door leaf and frame, enhances the sealing effect. Furthermore, the rubber layer prevents excessive displacement or deformation during door opening, closing, or vibration, ensuring long-term sealing stability. The rubber layer is secured through multiple limiting methods, including adhesive, snap-fit ​​ends, protruding ends, connecting shafts, and round ends, making it less prone to displacement or wrinkling and extending its service life. Additionally, the rubber layer is easy to disassemble and replace, facilitating maintenance. Moreover, because the rubber layer is sandwiched within the visible seam, it is less likely to be excessively compressed even during impacts when opening and closing the door.

[0017] 3. The steps one and two on the sides of the door frame and door leaf are staggered to form a curved, visible gap passage, which effectively prevents external tools from being inserted to pry open the door and improves the anti-theft performance of the entrance door.

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0023] This embodiment mainly describes the structure of the visible seam construction for entrance doors. Please refer to [link / reference]. Figures 1-8 Specifically, as follows: Currently, when installing an entrance door, the gap between the door frame 1 and the entrance door is intentionally retained, ultimately forming a clear and neat gap line. At the same time, the door leaf 2 and the door frame 1 form a complete plane without any protrusions or depressions. However, the sealing degree in the opening and closing of the entrance door with the visible gap is limited. Therefore, the structure of the entrance door with the visible gap is proposed, including the door frame 1 and the door leaf 2. A connector 3 for opening and closing is provided between the door frame 1 and the door leaf 2. The door frame 1 has an inward-facing cavity 11 for installing the connector 3. One side of the door leaf 2 has an integral extension surface 21 for blocking the cavity 11 and forming a visible gap with the door frame 1. The other side of the door leaf 2 also forms a visible gap with the door frame 1. The outer side of the door leaf 2 has a rubber layer 4 for sealing, and the rubber layer 4 is used to press against the door leaf 2; The connector 3 includes a fixed flap 31 fixed to the inner wall of the cavity 11, a movable flap 34 fixed to the door leaf 2, and a spindle 33 passing through the fixed flap 31 and the movable flap 34. The fixed flap 31 has a blocking end 32 on both the upper and lower sides. The blocking end 32 abuts against the movable flap 34 when the door leaf 2 is closed.

[0024] Specifically, both the door frame 1 and the door leaf 2 are existing structures, and the way they fit together through curved surfaces and form a complete plane are also existing. The rubber layer 4 is connected to the door leaf 2, and during the opening and closing of the door leaf 2, it is squeezed against the door frame 1 to achieve a sealing effect. The connector 3 acts as a hinge component to hinge the door leaf 2 to the door frame 1, allowing the door leaf 2 to open and close. It should be noted that the blocking end 32 in the connector 3 is used to abut against the closed movable leaf 34, meaning that the door leaf 2 encounters resistance at the end of its closing movement, preventing the door leaf 2 from directly impacting the door frame 1 and reducing the risk of excessive compression of the rubber layer 4.

[0025] like Figure 6 As shown, one side of the door leaf 2 with the extended surface 21 is flush with one edge of the door frame 1, and the other side of the door leaf 2 is flush with the other side of the door frame 1. The door leaf 2 and the door frame 1 can be flush, allowing the door to better integrate into the wall and making the space look cleaner and more upscale.

[0026] like Figures 5-8 As shown, the side surface of the door leaf 2 that mates with the door frame 1 has an integral baffle 22, and the rubber layer 4 is disposed on the outward side of the baffle 22 and abuts against the baffle 22.

[0027] Specifically, the function of the baffle 22 is to support the rubber layer 4. During the closing process of the door leaf 2, it is squeezed against the rubber layer 4, which can easily push the rubber layer 4 and cause the position of the rubber layer 4 to deviate. However, if one end of the rubber layer 4 is blocked, the displacement of the rubber layer 4 will be reduced to a certain extent.

[0028] like Figures 5-8 As shown, the side of the rubber layer 4 that is in contact with the door leaf 2 is bonded to the door leaf 2.

[0029] Specifically, the rubber layer 4, through its adhesive properties, facilitates separation from the door leaf 2. After the rubber layer 4 ages, it is easy to separate from the door leaf 2.

[0030] like Figures 6-7 As shown, the outer side of the door leaf 2 is provided with step 23, and the inner side of the door frame 1 is provided with step 12. Step 12 and step 23 are staggered to form a curved passage.

[0031] Specifically, by setting steps 12 and 23, the visible seam between the door leaf 2 and the door frame 1 extends outward in a curved manner, making it difficult for external tools to extend inward and increasing safety.

[0032] like Figures 6-7 As shown, the outward end of the rubber layer 4 abuts against step 12, and the outward end of the rubber layer 4 also has a fastening end 41, which fastens to the outside of step 23.

[0033] Specifically, the snap-fit ​​end 41 in the rubber layer 4 snaps into step 23, and the rubber layer 4 is confined, making it difficult for the rubber layer 4 to be displaced. In addition, since step 12 and step 23 are staggered, the snap-fit ​​end 41 is subjected to less compression when step 12 squeezes the end of the rubber layer 4.

[0034] like Figure 8 As shown, the rubber layer 4 has an integral protruding end 42 on one side facing inward. The protruding end 42 is attached to the baffle 22. The inner walls on both sides of the cavity 11 are a longitudinal surface 111 and a transverse surface 112, respectively. There is a gap between the transverse surface 112 and the baffle 22. The protruding end 42 is clamped in the gap between the transverse surface 112 and the baffle 22.

[0035] Specifically, the function of the protruding end 42 is to fit against the horizontal surface 112, limit the rubber layer 4, so that both ends of the rubber layer 4 are limited, and at the same time, it can increase the contact area between the rubber layer 4 and the door frame 1 and the door leaf 2, thereby improving the sealing effect.

[0036] like Figure 6 As shown, the blocking end 32 is attached to the horizontal surface 112, thus fixing the position of the blocking end 32. Specifically, after the blocking end 32 is pushed by the movable leaf 34, the blocking end 32 is supported by the door frame 1, so its position will not change, ensuring that the movable leaf 34 is supported.

[0037] like Figures 7-8 As shown, the protruding end 42 has an integral connecting shaft 43 extending from the baffle 22 on its inward side, and the end of the connecting shaft 43 has an integral round end 44 that abuts against the baffle 22.

[0038] The connecting shaft 43 and the round end 44 are also made of rubber and are used to engage with the baffle 22.

[0039] Specifically, the connecting shaft 43 and the round end 44 are integrated with the rubber layer 4 to limit the rubber layer 4 and the baffle 22, which facilitates subsequent installation and disassembly and minimizes the displacement of the rubber layer 4 during door opening and closing, thus affecting the sealing effect.

[0040] Working principle: The door frame 1 is hinged to the door leaf 2 through the connector 3. The door frame 1 is fixed to the wall. When the door leaf 2 is closed, the movable leaf 34 contacts the blocking end 32, so that the door leaf 2 is closed and the door leaf 2 is embedded in the door frame 1. The two sides of the door leaf 2 can be flush with the two sides of the door frame 1, and there is a visible seam between them. The door leaf 2 and the door frame 1 form a complete plane without any protrusions or depressions. During the opening and closing of the door leaf 2, the rubber layer 4 increases the contact area with the door frame 1 and the door leaf 2 due to the fastening end 41 and the protruding end 42, thereby improving the sealing effect. In addition, the step 12 and step 23 are staggered to each other, so that the exposed seam is in a certain tortuous state, which improves the safety. The outward end of the rubber layer 4 abuts against the step 12. Even if it is subjected to the pressure of the step 12, the pressure will be transmitted along the rubber layer 4, and the rubber layer 4 will not be clamped by excessive force from both sides.

[0041] Secondly, after the door leaf 2 is locked to the door frame 1, the door leaf 2 may wobble. Therefore, by setting the fastening end 41 to fasten with the step 23 and the protruding end 42 to contact the horizontal surface 112, both ends of the rubber layer 4 are limited, preventing the rubber layer 4 from wrinkling and maintaining its original shape.

[0042] In addition, during the opening and closing of the door leaf 2, the door frame 1 will be squeezed against the rubber layer 4, which may easily cause the rubber layer 4 to shift. By passing the round end 44 through the baffle 22, the connecting shaft 43 and the round end 44 limit the rubber layer 4 to fit against the baffle 22, making it less likely for the position of the rubber layer 4 to change. When the rubber layer 4 needs to be replaced, the connecting shaft 43 and the round end 44 are separated from the baffle 22, and the rubber layer 4 can be torn off, which facilitates subsequent replacement and fixation.

[0043] Due to the effects of step 12, step 23, and rubber layer 4, the degree of tortuosity of the visible seam is limited, making it less likely for impurities to get stuck and easier to clean.
