Description

Technical Field

[0001] The present application relates to the technical field of door leafs, and more specifically, to a door leaf pressure strip assembly and a door leaf structure. Background Art

[0002] Doors with glass generally require door strips to fix the glass in place, in order to enhance the sealing and stability between the door and the glass.

[0003] At present, the door leaf moldings are usually solid materials. After cutting at a 45-degree angle, four door leaf moldings are connected in pairs by gluing the joint surfaces to form a rectangular frame. However, the two door leaf moldings assembled in this way are prone to misalignment at the 45-degree angle, or unevenness at the corner after framing, affecting the overall appearance of the door leaf. At the same time, when the door leaf moldings after framing are assembled with the door leaf on both sides, a tooling fixture is required to clamp the door leaf moldings, and the corners are prone to cracking when squeezed by external force.

[0004] There are currently some patents for improvements to 45-degree corner components, but these patents still have some defects. For example, the Chinese patent application "A 45-degree connection structure for wood-plastic parts" (application number 202122077742.2, application date August 31, 2021) discloses inserting one end of the connecting angle code into the inner hole of one of the wood-plastic parts, and the other end into the inner hole of the other wood-plastic part, and using an L-shaped connecting angle code to achieve a 45-degree splicing of the two wood-plastic parts, thereby improving the connection strength. However, the connecting angle code in this patent is still bonded to the wood-plastic part, and the concave and convex grooves on the surface of the connecting angle code are designed to follow the extension direction of the angle code. When squeezed by external force, the strength of the entire connection structure is still limited, and it is difficult to ensure that cracks do not occur at the corner. Utility Model Content

[0044] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0045] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0046] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0047] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0048] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0049] Doors with glass generally require door strips to fix the glass in place, in order to enhance the sealing and stability between the door and the glass.

[0050] At present, the door leaf moldings are usually solid materials. After cutting at a 45-degree angle, four door leaf moldings are assembled into a rectangular frame. The joint surfaces of the two adjacent door leaf moldings are glued together to achieve a 45-degree joint, and then the door leaf moldings after the frame are further fixed by air gun nails. However, the two door leaf moldings assembled in this way are prone to being out of square at the 45-degree angle, that is, the 45-degree angle does not match up, and there is a misalignment, or after the 45-degree joint, the visible surface of the door leaf molding at the corner is misaligned, resulting in step-like unevenness of the two door leaf moldings at the corner, affecting the overall appearance; at the same time, when the door leaf molding after the frame is assembled with the door leaf on both sides, a fixture is required to clamp the door leaf molding, and the 45-degree angle fixed by bonding is not strong enough, and it is easy to crack or even fall off when squeezed by external force.

[0051] In order to solve the above technical problems, the present application proposes a door leaf molding assembly and a door leaf structure, which are used to improve the strength of the door leaf molding assembly at the corners, and to ensure that the corners are not easy to crack when subsequently squeezed by external forces, thereby improving the structural stability of the entire door leaf molding assembly.

[0052] The following is a detailed description with reference to the accompanying drawings and specific embodiments.

[0053] Figure 1 The figure shows a structural schematic diagram of a door leaf pressure strip assembly provided in an embodiment of the present application; Figure 2 The figure shows an assembly schematic diagram of a door leaf pressure strip assembly provided in an embodiment of the present application; Figure 3 The figure shows a structural schematic diagram of a door leaf pressure strip structure provided in an embodiment of the present application; Figure 4 The figure shows a structural schematic diagram of an L-shaped connection angle code provided in an embodiment of the present application; Figure 5 Shown is a side view of the L-shaped connection angle code provided in an embodiment of the present application.

[0054] like Figure 1 to Figure 5 As shown, an embodiment of the present application provides a door leaf beading assembly, the door leaf beading assembly includes two door leaf beading structures 1 and an L-shaped connecting angle code 2, and the two door leaf beading structures 1 are vertically spliced ​​by the L-shaped connecting angle code 2;

[0055] One end of the door leaf beading structure 1 is an inclined end surface 10, and the angle between the inclined end surface 10 and the vertical section of the corresponding door leaf beading structure 1 is 45°. The inclined end surfaces 10 of the two door leaf beading structures 1 are fixed by bonding adhesive.

[0056] The vertical cross section of the door leaf bead structure 1 is a cross section perpendicular to the length direction of the corresponding door leaf bead structure 1;

[0057] The L-shaped connecting angle bracket 2 has two extension parts 20 connected at the ends, and the length directions of the two extension parts 20 are perpendicular to each other; the extension part 20 has a connecting end 201 and a free end 202, and the two extension parts 20 are connected to each other through the connecting end 201;

[0058] The door leaf beading structure 1 has a cavity 11 inside for accommodating the extension portion 20. The cavity 11 extends along the length direction of the door leaf beading structure 1 and at least penetrates the inclined end surface 10 of the corresponding door leaf beading structure 1.

[0059] The length of the cavity 11 in the length direction of the corresponding door leaf beading structure 1 is greater than or equal to the length of the extension 20 in the length direction of the corresponding extension 20, the width of the cavity 11 in the width direction of the corresponding door leaf beading structure 1 is greater than or equal to the width of the extension 20 in the width direction of the corresponding extension 20, and the thickness of the cavity 11 in the thickness direction of the corresponding door leaf beading structure 1 is greater than or equal to the thickness of the extension 20 in the thickness direction of the corresponding extension 20;

[0060] The length direction, width direction and thickness direction of the door leaf molding structure 1 are perpendicular to each other, and the length direction, width direction and thickness direction of the extension part 20 are perpendicular to each other;

[0061] The surface of the L-shaped connecting angle code 2 has a plurality of protrusion structures 21 spaced apart along the length direction of the corresponding extension portion 20, and the protrusion structures 21 extend along the width direction of the corresponding extension portion 20;

[0062] The extension part 20 is also provided with a connection hole 22 penetrating the extension part 20 along the thickness direction of the corresponding extension part 20; the door leaf pressure strip structure 1 is provided with a self-tapping screw hole (not shown in the figure) corresponding to the connection hole 22;

[0063] The two door leaf pressure strip structures 1 are threadedly connected to the extension portion 20 of the L-shaped connection angle bracket 2 through corresponding self-tapping screw holes and connection holes 22 respectively.

[0064] When implementing it, Figure 1 to Figure 5 As shown, the free end 202 of the extension portion 20 is aligned with the opening of the cavity 11 at the inclined end surface 10, and the extension portion 20 is inserted into the cavity 11 of the door leaf molding structure 1 from the inclined end surface 10. Then, according to the position of the connecting hole 22 on the extension portion 20, a hole is opened at the corresponding position of the door leaf molding structure 1 using a self-tapping screw, so that the self-tapping screw forms a self-tapping screw hole on the door leaf molding structure 1; adhesive is applied to the inclined end surfaces 10 of the two door leaf molding structures 1, and the two inclined end surfaces 10 are bonded and fixed using the adhesive; then, the self-tapping screw is installed so that the self-tapping screw passes through the self-tapping screw hole on the door leaf molding structure 1 and the connecting hole 22 on the extension portion 20, and the splicing of the door leaf molding assembly is completed.

[0065] Through the composition structure and specific implementation process of the above-mentioned door leaf pressure strip assembly, it can be known that Figure 1 to Figure 5As shown, the door strip assembly includes two door strip structures 1 and an L-shaped connecting angle code 2, wherein one end of the door strip structure 1 has an inclined end surface 10 inclined at 45° relative to the vertical section, so that the two door strip structures 1 can be spliced ​​into a right angle by splicing the inclined end surfaces 10 with each other; the interior of the door strip structure 1 also has a cavity 11 extending along the length direction of the door strip structure 1, and the cavity 11 at least penetrates the inclined end surface 10 of the corresponding door strip structure 1, and the length, width and thickness of the extension part 20 are respectively less than or equal to the length, width and thickness of the cavity 11, so that the L-shaped connecting angle code 2 can be inserted into the cavity 11 through the free end 202 of the extension part 20 from the opening of the cavity 11 at the inclined end surface 10, thereby realizing the splicing of the L-shaped connecting angle code 2 and the two door strip structures 1. The inclined end surfaces 10 of the two door leaf molding structures 1 can be bonded and fixed by adhesive; the extension part 20 is also provided with a connecting hole 22 that penetrates the extension part 20 along its thickness direction, and a self-tapping screw hole corresponding to the connecting hole 22 is provided at a corresponding position of the door leaf molding structure 1, so that after the extension part 20 is inserted into the cavity 11, the door leaf molding structure 1 and the extension part 20 can be threadedly connected through the self-tapping screw hole and the connecting hole 22. It can be seen that the embodiment of the present application makes changes to the door leaf molding structure 1, opens a cavity 11 inside the door leaf molding structure 1, and adds an L-shaped connecting angle code 2 for installation in coordination with the cavity 11, so that the two door leaf molding structures 1 can be spliced ​​at 45° through a combined installation method of an angle code and an adhesive splicing surface, and the L-shaped connecting angle code 2 and the door leaf molding structure 1 are threadedly connected, thereby improving the strength of the door leaf molding assembly at the splicing corners. When the clamping tool is used for subsequent clamping and installation, it can be ensured as much as possible that the splicing corners are not easy to crack or fall off when squeezed by external force, thereby improving the structural stability of the entire door leaf molding assembly and improving product quality; at the same time, the assembled door leaf molding assembly will not have step-like unevenness or misalignment at the splicing corners, thereby improving the overall aesthetic effect. At the same time, the surface of the L-shaped connecting angle code 2 has a plurality of spaced-apart protrusion structures 21, which extend along the width direction of the corresponding extension portion 20, and a plurality of protrusion structures 21 are spaced-apart along the length direction of the corresponding extension portion 20, so that when the extension portion 20 is inserted into the cavity 11, the extension direction of each protrusion structure 21 is perpendicular to the movement direction of the extension portion 20 in the cavity 11. The L-shaped connecting angle code 2 with this structure is more suitable for connecting the door leaf molding structure 1, which can increase the friction between the extension portion 20 and the cavity 11, so that the extension portion 20 is not easy to fall off from the cavity 11, and at the same time further improves the connection strength between the L-shaped connecting angle code 2 and the door leaf molding structure 1, thereby further effectively reducing the cracking of the corners of the door leaf molding assembly when squeezed by external force, and further improving the structural stability of the door leaf molding assembly.

[0066] In addition, adhesive can be added between the extension of the L-shaped connecting angle code and the cavity of the door leaf molding assembly, so that the L-shaped connecting angle code and the door leaf molding assembly are fixed by a combination of threaded connection and gluing. At this time, the raised structures distributed at intervals on the outer surface of the L-shaped connecting angle code can not only guide the glue and control the overflow of the glue, but also because when the extension part is inserted into the cavity, the extension direction of the raised structure is perpendicular to the movement direction of the extension part in the cavity, and the raised structure can also be stuck between two adjacent raised structures after the adhesive is cured, thereby further improving the connection strength between the L-shaped connecting angle code and the door leaf molding structure, thereby further reducing the cracking of the corners of the door leaf molding assembly when squeezed by external force, and further improving the structural stability of the door leaf molding assembly.

[0067] It should be noted that the self-tapping screw holes opened on the door strip structure are corresponding holes punched when the L-shaped connecting angle code and the door strip structure are fixed with self-tapping screws, which are not shown in the accompanying drawings. That is, before fixing the door strip structure and the L-shaped connecting angle code, first measure the hole positions of the connecting holes on the extended part of the L-shaped connecting angle code, mark the corresponding hole positions on the door strip structure, and after inserting the L-shaped connecting angle code into the cavity of the door strip structure, use self-tapping screws to punch holes on the door strip structure, thereby forming self-tapping screw holes on the door strip structure corresponding to the connecting holes on the L-shaped connecting angle code.

[0068] As a possible implementation, the difference between the width of the cavity in the width direction of the corresponding door leaf molding structure and the width of the extension in the width direction of the corresponding extension is between [0, 0.1] mm;

[0069] The difference between the thickness of the cavity in the thickness direction of the corresponding door leaf molding structure and the thickness of the extension in the thickness direction of the corresponding extension is between [0, 0.1] mm.

[0070] Based on this, the cavity of the door leaf molding structure may have an error of 0 to 0.1 mm between the width in the width direction of the corresponding door leaf molding structure and the width of the extension part in the width direction of the corresponding extension part, and the cavity in the door leaf molding structure may have an error of 0 to 0.1 mm between the thickness in the thickness direction of the corresponding door leaf molding structure and the thickness of the extension part in the thickness direction of the corresponding extension part. Within this error range, the extension part can achieve better fit when inserted into the cavity of the door leaf molding structure, which can further improve the strength of the door leaf molding assembly at the corners, further ensure that the corners are not easy to crack or fall off when squeezed by external force, thereby further improving the structural stability of the entire door leaf molding assembly, and improving the product quality and overall aesthetic effect; if the error is too large, shaking may occur between the extension part and the cavity, which is not conducive to ensuring the strength of the door leaf molding assembly at the corners.

[0071] In some examples, the difference between the width of the cavity in the width direction of the corresponding door leaf molding structure and the width of the extension in the width direction of the corresponding extension is between [0,0.1] mm, which means that the difference between the width of the cavity in the width direction of the corresponding door leaf molding structure and the width of the extension in the width direction of the corresponding extension is greater than or equal to zero and less than or equal to 0.1 mm; the difference between the thickness of the cavity in the thickness direction of the corresponding door leaf molding structure and the thickness of the extension in the thickness direction of the corresponding extension is between [0,0.1] mm, which means that the difference between the thickness of the cavity in the thickness direction of the corresponding door leaf molding structure and the thickness of the extension in the thickness direction of the corresponding extension is greater than or equal to zero and less than or equal to 0.1 mm.

[0072] In some examples, the difference between the width of the cavity in the width direction of the corresponding door leaf molding structure and the width of the extension in the width direction of the corresponding extension can be any range or any value between [0, 0.1] mm. For example, the difference between the width of the cavity in the width direction of the corresponding door leaf molding structure and the width of the extension in the width direction of the corresponding extension can be between [0, 0.03] mm, [0.03, 0.06] mm or [0.06, 0.1] mm, etc. For example, the difference between the width of the cavity in the width direction of the corresponding door leaf molding structure and the width of the extension in the width direction of the corresponding extension can be 0, 0.02 mm, 0.03 mm, 0.04 mm, 0.06 mm, 0.08 mm, 0.09 mm or 1 mm, etc.; at the same time, the cavity The difference between the thickness of the corresponding door leaf molding structure in the thickness direction and the thickness of the extension part in the thickness direction of the corresponding extension part can be any range or any value between [0, 0.1] mm. For example, the difference between the thickness of the cavity in the thickness direction of the corresponding door leaf molding structure and the thickness of the extension part in the thickness direction of the corresponding extension part can be between [0, 0.03] mm, [0.03, 0.06] mm or [0.06, 0.1] mm, etc. For example, the difference between the thickness of the cavity in the thickness direction of the corresponding door leaf molding structure and the thickness of the extension part in the thickness direction of the corresponding extension part can be 0 mm, 0.02 mm, 0.03 mm, 0.04 mm, 0.06 mm, 0.08 mm, 0.09 mm or 1 mm, etc. This is just an example and is not specifically limited.

[0073] In some examples, along the length direction of the corresponding door leaf molding structure, the cavity can pass through both ends of the door leaf molding structure. In actual production, the material with the cavity extending along the length direction can be directly processed, and then the material with the cavity is finely cut at an angle of 45° to obtain the door leaf molding structure to be assembled.

[0074] As a possible implementation, Figure 4 and Figure 5 As shown, the protruding structure 21 protrudes from the corresponding extending portion 20 along the thickness direction of the corresponding extending portion 20; the cross-sectional shape of the protruding structure 21 at least includes one or more of a polygon, a circle, an ellipse, and a shape composed of line segments and curves;

[0075] The cross-sectional diagram of the protruding structure 21 is a cross-sectional diagram of the protruding structure 21 on a plane formed by the thickness direction of the extending portion 20 and the length direction of the extending portion 20 .

[0076] Based on this, Figure 4 and Figure 5 As shown, with the plane formed by the thickness direction and the length direction of the extension part 20 as the cross-section, the cross-sectional figure of the raised structure 21 may include a variety of figures, for example, it may include any one of polygons, circles, ellipses, and figures composed of line segments and curves, etc., or it may include a combination of two or more of polygons, circles, ellipses, and figures composed of line segments and curves, etc., so that the raised structure 21 on the L-shaped connecting angle code 2 can be designed according to different situations, so as to achieve targeted strengthening of the strength of the door leaf molding assembly at the corner according to actual needs, further effectively reduce the difficulty of cracking or falling off at the corner when squeezed by external force, further improve the structural stability of the entire door leaf molding assembly, improve the quality of the product and the overall aesthetic effect, and at the same time improve the scope of application of the entire door leaf molding assembly.

Among them, Figure 6 , Figure 7 and Figure 8 The door leaf structure and door leaf shown in the figure are for illustration only and do not represent the actual door leaf structure and the size and proportion of the door leaf.

[0078] As a possible implementation, Figure 1 to Figure 3 and Figure 6 to Figure 8 As shown, the door leaf molding structure 1 has an inner side wall 12 and an outer side wall 13 opposite to each other;

[0079] The self-tapping screw hole penetrates the outer side wall 13 of the corresponding door leaf beading structure 1 along the thickness direction of the corresponding door leaf beading structure 1;

[0080] On the inner side wall 12 of the door leaf molding structure 1, the door leaf molding structure 1 also has a plurality of tooth-like grooves 14 extending along the length direction of the door leaf molding structure 1 and spaced apart along the width direction of the door leaf molding structure 1, and a limiting protrusion 15 extending along the length direction of the door leaf molding structure 1, and the limiting protrusion 15 is located on one side of the tooth-like groove 14.

[0081] Based on this, Figure 1 to Figure 3 and Figure 6 to Figure 8 As shown, the door leaf molding structure 1 has two opposite side walls, wherein the inner side wall 12 is used for installation with the door leaf, and the outer side wall 13 is provided with self-tapping screw holes penetrating along the thickness direction of the corresponding door leaf molding structure 1. The door leaf molding structure 1 has a limiting protrusion 15 and a plurality of toothed grooves 14 on the inner side wall 12, wherein the limiting protrusion 15 can clamp the door leaf and limit the displacement of the door leaf molding structure 1 when the door leaf molding structure 1 is installed on the door leaf; when the door leaf and the door leaf molding structure 1 are subsequently glued, the space provided by the plurality of toothed grooves 14 and the space between the toothed grooves 14 and the limiting protrusion 15 can guide the glue and control the overflow of the glue, and at the same time make the bonding effect between the door leaf and the door leaf molding structure 1 better, while improving the strength of the door leaf molding structure 1 at the corner, and ensuring that the corner is not easy to crack and fall off when squeezed by external force, while improving the structural stability of the door leaf molding assembly, the connection strength between the door leaf molding assembly and the door leaf structure is improved, thereby improving the structural stability of the entire door leaf structure, and at the same time improving the quality of the product and the overall aesthetic effect.

[0082] As a possible implementation, Figure 1-2 and Figure 4-5 As shown, the two extension portions 20 intersect vertically through the connecting end 201 , and an avoidance groove 23 is provided on the inner side of the intersection of the two extension portions 20 , and the avoidance groove 23 extends along the width direction of the extension portion 20 .

[0083] Based on this, Figure 1-2 and Figure 4-5As shown, the two extension portions 20 are connected at their ends via a connecting end 201 to form a vertically intersecting L-shaped connecting angle code 2. An avoidance groove 23 is provided on the inner side of the intersection of the two extension parts 20. When the two door leaf molding structures 1 are spliced ​​and assembled with the L-shaped connecting angle code 2, if the avoidance groove 23 is not provided on the inner side of the corner of the L-shaped connecting angle code 2, and it is a right-angle corner, then after the two extension parts 20 of the L-shaped connecting angle code 2 are respectively inserted into the cavities 11 of the two door leaf molding structures 1, the door leaf molding structure 1 will conflict with the outer side of the corner of the L-shaped connecting angle code 2, and the inclined end surfaces 10 of the two door leaf molding structures 1 are difficult to contact each other. After the avoidance groove 23 is provided on the inner side of the corner, the door leaf molding structure 1 and the L-shaped connecting angle code 2 can be well assembled, which is beneficial to further improve the strength of the door leaf molding assembly at the splicing corner, and at the same time, it is beneficial to further ensure that the splicing corner is not easy to crack or fall off when squeezed by external force, thereby further improving the structural stability of the entire door leaf molding assembly, and improving the quality of the product and the overall aesthetic effect.

[0084] In some examples, the material of the door leaf molding structure can be wood plastic, density board, solid wood, aluminum alloy or stainless steel, etc., and the material of the L-shaped connecting angle code can be plastic, aluminum alloy, wood, etc. These are just examples here, and you can choose from the existing materials according to the material of the door leaf structure and actual needs.

[0085] For example, the material of the door leaf molding structure may be wood plastic, and the material of the L-shaped connecting corner code may be a terpolymer of acrylonitrile, butadiene, and styrene (Acrylonitrile Butadiene Styrene plastic, ABS), which is only used as an example and is not specifically limited.

[0086] Based on the same inventive concept, Figure 6 As shown, the present application also provides a door leaf structure, which includes the door leaf pressure strip assembly described in the above embodiment.

[0087] Compared with the prior art, the beneficial effects of the door leaf structure are the same as the beneficial effects of the door leaf pressure strip assembly described in the above embodiment, and will not be repeated here.

[0088] As a possible implementation, Figure 6 to Figure 8 As shown, the door leaf structure includes glass 4, a door leaf 3 and two door leaf pressure strip frames 5, and the glass 4 is installed on the door leaf 3; each door leaf pressure strip frame 5 is composed of two door leaf pressure strip assemblies, and the two door leaf pressure strip frames 5 clamp the glass 4 from opposite sides of the door leaf 3 respectively.

[0089] Based on this, before assembling with the door leaf 3, the door leaf beading structure 1 needs to be assembled into a rectangular door leaf beading frame 5 through the L-shaped connecting angle code 2. The door leaf beading frame 5 is composed of four door leaf beading structures 1 connected end to end, and two adjacent door leaf beading structures 1 are connected at 45 degrees through the L-shaped connecting angle code. After the door leaf beading frame 5 is assembled, the two door leaf beading frames 5 are respectively installed on both sides of the door leaf 3 using a fixture, so as to realize the double-sided assembly of the door leaf beading frame 5 and the door leaf 3, so that the glass 4 can be clamped in the middle of the two door leaf beading frames 5. Since the embodiment of the present application opens a cavity 11 inside the door leaf molding structure 1, and adds an L-shaped connecting angle code for installation in coordination with the cavity 11, the two door leaf molding structures 1 can be spliced ​​at 45° by a combination of the angle code and the adhesive splicing surface, and the L-shaped connecting angle code and the door leaf molding structure 1 are threadedly connected, thereby improving the strength of the door leaf molding frame 5 at the splicing corners. When clamping and installing with a fixture, it can be ensured as much as possible that the splicing corners are not prone to cracking or falling off when squeezed by external forces, thereby improving the structural stability of the entire door leaf structure and improving the product quality. At the same time, the assembled door leaf molding frame 5 will not have step-like unevenness or misalignment at the splicing corners, thereby improving the overall aesthetic effect of the door leaf structure.

[0090] In summary, the door leaf pressure strip assembly and door leaf structure provided by the present application achieve at least the following beneficial effects:

[0091] The interior of the door leaf beading structure has a cavity extending along the length direction of the door leaf beading structure, and the cavity at least penetrates the inclined end face of the corresponding door leaf beading structure, so that the L-shaped connection angle code can be inserted into the cavity from the opening of the cavity at the inclined end face, so as to realize the splicing of the L-shaped connection angle code and the two door leaf beading structures. The inclined end faces of the two door leaf beading structures can be bonded and fixed by adhesive; the extension part is also provided with a connection hole penetrating the extension part along the thickness direction thereof, and a self-tapping screw hole corresponding to the connection hole is provided at a corresponding position of the door leaf beading structure, so that the door leaf beading structure and the extension part can be threadedly connected through the self-tapping screw hole and the connection hole. It can be seen that the two door leaf molding structures can be spliced ​​at 45° through the combined installation method of angle brackets and adhesive joint surfaces, and the L-shaped connection angle bracket and the door leaf molding structure are threadedly connected, which improves the strength of the door leaf molding assembly at the corner, and can ensure as much as possible that the corner is not easy to crack or fall off when squeezed by external force, thereby improving the structural stability of the entire door leaf molding assembly and improving product quality; at the same time, it improves the overall aesthetic effect.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
