Description

Technical Field

[0001] This utility model relates to the field of home building materials technology, and in particular to a door panel embedded positioning anti-cracking structure. Background Technology

[0002] In the structure of traditional door panels, when the door panel is heated, the door frame will deform irregularly due to thermal expansion. When it cools down, it will shrink. Over time, the door panel will crack. At the same time, the corners of the door frame are usually assembled using a 45° splicing process, and the splices need to be fixed with glue. However, the existing door frame corners do not have an effective anti-overflow glue structure, and glue can easily overflow from the splice gaps towards the door panel, causing pollution. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes an embedded positioning anti-cracking structure for door panels.

[0004] This utility model proposes an embedded positioning anti-cracking structure for door panels, including a door frame and a door panel. The door panel includes a first door panel and a second door panel that are fixedly connected. The bottom of the connection between the first door panel and the second door panel is connected with a positioning protrusion. The door frame has a connected positioning groove and a slot inside. The door panel is inserted and fixed in the slot. After being inserted into place, the positioning protrusion engages inside the positioning groove to restrain the door panel from cracking after thermal expansion. Corner sleeves are embedded at the corners of the door frame to prevent glue from overflowing from the 45° splice of the door frame toward the door panel.

[0005] Furthermore, the door frame includes a first panel and a second panel, both of which are wood grain decorative panels.

[0006] Furthermore, the first panel and the second panel are connected together by several connected inner core plates, and the positioning groove is opened at the bottom of the innermost inner core plate.

[0007] Furthermore, the opposite ends of the first and second door panels are provided with slots to engage with the door frame.

[0008] Furthermore, the corner sleeve is designed with an L-shaped structure and is made of plastic.

[0009] Furthermore, the adjacent end faces of the first panel and the second panel, as well as the surface of the innermost core board, are provided with grooves, and the corner sleeves are embedded and fixed in the grooves and are compatible with each other.

[0010] The beneficial effects of this utility model are as follows: By setting positioning protrusions at the bottom of the first and second door panels and opening matching positioning grooves in the door frame, the engagement of the positioning protrusions and positioning grooves can effectively constrain the deformation of the door panel when it expands due to heat, avoiding cracking caused by long-term thermal expansion and contraction; at the same time, the L-shaped corner sleeves made of plastic material embedded in the corners of the door frame can form a sealed shield at the 45° splicing point of the door frame, preventing the glue used for splicing from overflowing towards the door panel, thereby simultaneously solving the problems of easy cracking of traditional door panels and glue overflow pollution at the splicing point of the door frame, ensuring the structural stability and appearance of the door panel, and extending the overall service life of the door panel.

[0013] Reference Figure 1-5 This utility model proposes an embedded positioning anti-cracking structure for door panels, including a door frame 1, a first door panel 2, and a second door panel 3. The adjacent ends of the first door panel 2 and the second door panel 3 are glued and fixed. At the bottom of the connection between the first door panel 2 and the second door panel 3, a positioning protrusion 4 is integrally formed. Correspondingly, a connected positioning groove 14 and a slot 15 are provided inside the door frame 1. The size of the slot 15 is adapted to the overall thickness of the door panel and is used for the insertion and fixing of the door panel. When the door panel is inserted into the slot 15 and reaches the preset installation position, the positioning protrusion 4 at the bottom of the first door panel 2 and the second door panel 3 will accurately engage inside the positioning groove 14. When the door panel expands due to changes in ambient temperature, the engagement relationship between the positioning protrusion 4 and the positioning groove 14 can effectively constrain the expansion direction of the door panel, avoid excessive internal stress caused by irregular expansion of the door panel, thereby preventing cracking of the door panel and ensuring the structural integrity and service life of the door panel. The door frame 1 also adopts a multi-layer composite structure to balance structural strength and aesthetic appearance. It mainly includes a first panel 11 and a second panel 12. Both the first panel 11 and the second panel 12 are made of wood grain decorative board. This material not only provides a beautiful appearance for the door frame 1 to meet the needs of different decoration styles, but also has certain wear resistance and scratch resistance, improving the practicality of the door frame 1. Between the first panel 11 and the second panel 12, several interlocking inner core panels 13 are fixedly connected. The setting of the inner core panels 13 greatly enhances the overall structural strength of the door frame 1 and prevents the door frame 1 from deforming during long-term use. The aforementioned positioning groove 14 is specifically opened at the bottom of the innermost inner core panel 13. This position design can ensure that the positioning groove 14 is precisely aligned with the positioning protrusion 4 at the bottom of the door panel, while not affecting the structural integrity and appearance of the outer panel of the door frame 1. To further enhance the stability of the connection between the door panel and the door frame 1, slots 5 are provided at the opposite ends of the first door panel 2 and the second door panel 3. When the door panel is inserted into the slot 15 of the door frame 1, the structure on the door frame 1 corresponding to the slot 5 will be embedded inside the slot 5, forming an additional locking relationship. This dual fixing method (slot insertion + slot locking) can effectively prevent the door panel from loosening or shifting during use, ensuring the stability of the door panel installation. To address the issue of glue overflow at the 45° corner of the door frame 1, this structure employs an embedded corner sleeve 6 design at the corner of the door frame 1. The corner sleeve 6 is designed as an L-shaped structure and made of plastic. Plastic has good shapeability and sealing properties, allowing it to fit tightly against the corner of the door frame 1. To ensure stable installation of the corner sleeve 6, grooves matching the shape and size of the corner sleeve 6 are provided on the adjacent end faces of the first panel 11, the second panel 12, and the surface of the innermost core panel 13. The corner sleeve 6 is embedded and fixed in these grooves. After installation, the corner sleeve 6 effectively shields and seals the 45° joint of the door frame 1, preventing glue generated during the splicing process from overflowing towards the door panel. This ensures the cleanliness of the connection between the door panel and the door frame 1 and avoids glue overflow from adversely affecting the performance and appearance of the door panel.
