Description

Technical Field

[0001] This utility model relates to the field of doors and windows, and in particular to a door leaf edge sealing strip and door leaf structure. Background Technology

[0002] Chinese patent document CN222184524U discloses a technical solution entitled "A Door Leaf Edge Sealing and Door Leaf Assembly." This technical solution includes the following features: a door leaf, a first door gap, a second door gap, a door leaf edge sealing, a nail, serrations, an edge banding portion, a positioning nail, a door leaf magnetic sealing element, a first fitting portion, a second fitting portion, a connecting portion, a door frame, and a door frame magnetic sealing element, etc. In this technical solution, only one door frame magnetic sealing element is used to achieve sealing between the door leaf and the door frame. This only creates a seal at one point between the door leaf and the door frame. Furthermore, there are still relatively large gaps in the first and second door gaps between the door leaf and the door frame. This easily leads to poor sound insulation and light-blocking performance between the door leaf and the door frame, resulting in a poor user experience. Although door edge banding systems capable of simultaneously installing two sealing strips have emerged, to accommodate the installation of both strips and ensure the structural strength of the edge banding, complex bending structures are used at two points to create mounting grooves for the two strips. This results in a complex structure, high manufacturing difficulty, and high production costs. Therefore, it is essential to design a door edge banding strip and door structure to address these technical challenges. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned problems and shortcomings, and to provide a door leaf edge banding strip and door leaf structure. This door leaf edge banding strip not only has a simple and reliable structure, but also helps to improve the sound insulation and light-blocking performance of the door, thereby providing users with a better user experience. It has the advantages of simple structure, low manufacturing difficulty, and low manufacturing cost. The door leaf structure can achieve better sound insulation and light-blocking effects, thereby providing users with a better user experience. It has the advantages of simple structure, high reliability, low manufacturing difficulty, low manufacturing cost, and strong applicability.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A door leaf edge sealing strip is characterized in that it includes an edge sealing strip, an outer side of which is provided with a turning notch for abutting a sealing strip, a positioning groove for mounting the sealing strip is provided on the outer wall of the edge sealing strip, and a thickened part is provided on the inner wall of the edge sealing strip, and the thickened part is arranged side by side with the positioning groove.

[0006] Preferably, one side of the edge sealing strip is a right-angled portion that bends inward toward its inner wall, and the inner wall of the right-angled portion forms a turning notch.

[0007] Preferably, the inner wall of the edge sealing strip is provided with at least one reinforcing ridge.

[0008] Preferably, the positioning groove and the turning notch are located on both sides of the outer wall of the edge sealing strip; the reinforcing ridge is located on the middle of the inner wall of the edge sealing strip.

[0009] Preferably, the front and rear ends of the edge sealing strip are raised tapered surfaces.

[0010] Preferably, a positioning groove is provided on the side of the tapered surface near the inner wall of the sealing strip.

[0011] Preferably, the side of the tapered surface near the outer wall of the edge sealing strip is a plane that transitions smoothly with the outer wall of the edge sealing strip, and the side of the tapered surface near the inner wall of the edge sealing strip is an inclined surface that slopes towards the outer wall of the edge sealing strip, and the positioning groove is formed on the inclined surface.

[0012] Preferably, at least one interlocking strip is provided on the inner wall of the edge sealing strip.

[0013] Preferably, the surface of the insert strip is provided with a plurality of barbed protrusions.

[0014] A door leaf structure includes a door leaf panel, characterized in that it also includes the aforementioned door leaf edge banding strip, which is disposed on the side wall of the door leaf panel.

[0015] The beneficial effects of this utility model are as follows: The edge banding strip utilizes an edge banding piece, which not only provides a good sealing effect but also simplifies the structure. A notch is provided on one outer edge of the edge banding piece for attaching a sealing strip. This notch not only creates a transitional gap between the door leaf and the door frame but also allows the sealing strip on the door frame to be attached, facilitating a first seal between the door leaf and the door frame. A positioning groove is provided on the outer wall of the edge banding piece for mounting the sealing strip, facilitating a second seal between the door leaf and the door frame. Thus, this door leaf edge banding strip effectively creates two seals between the door leaf and the door frame, thereby improving the sound insulation and light-blocking performance between them, ultimately providing a better user experience. A thickened section is provided on the inner wall of the edge banding strip, and this thickened section is arranged side by side with the positioning groove. This not only ensures a relatively simple overall structure of the door leaf edge banding strip, but also enhances the structural strength of the positioning groove by utilizing the thickened section. Thus, while achieving a simple structure, the door leaf edge banding strip possesses a highly stable and reliable structure. Furthermore, the overall structure of this door leaf edge banding strip is relatively simple, which not only reduces manufacturing difficulty but also lowers manufacturing costs.

[0016] This door structure, with its edge banding, provides more reliable sound insulation and light blocking, resulting in a better user experience. Furthermore, this simple and reliable structure not only facilitates manufacturing and reduces costs but also offers strong applicability. Attached Figure Description

[0021] Example

[0022] like Figure 1As shown, the door leaf edge sealing strip of this utility model includes an edge sealing strip 1. The outer side of the edge sealing strip 1 is provided with a turning notch 11 for attaching a sealing strip. The outer wall of the edge sealing strip 1 is provided with a positioning groove 12 for mounting the sealing strip. The inner wall of the edge sealing strip 1 is provided with a thickened part 13, and the thickened part 13 and the positioning groove 12 are arranged side by side.

[0023] The door leaf edge banding strip uses an edge banding piece 1, which not only provides a good edge banding effect but also a simple structure. A notch 11 for attaching a sealing strip is provided on one outer edge of the edge banding piece 1. This notch not only creates a transition gap between the door leaf and the door frame but also allows the sealing strip on the door frame to be attached, thus forming a first seal between the door leaf and the door frame. A positioning groove 12 for mounting the sealing strip is provided on the outer wall of the edge banding piece 1, forming a second seal between the door leaf and the door frame. In this way, the door leaf edge banding strip can form two seals between the door leaf and the door frame, effectively improving the sound insulation and light-blocking performance between the door leaf and the door frame, thereby providing a better user experience. A thickened portion 13 is provided on the inner wall of the edge banding strip 1, and the thickened portion 13 and the positioning groove 12 are arranged side by side. This not only ensures that the overall structure of the door leaf edge banding strip is relatively simple, but also enhances the structural strength of the opening of the positioning groove 12 by utilizing the thickened portion 13. Thus, the door leaf edge banding strip has a very stable and reliable structure while achieving a simple structure. At the same time, the overall structure of the door leaf edge banding strip is relatively simple, which not only reduces the manufacturing difficulty, but also reduces the manufacturing cost.

[0024] like Figure 1 As shown, the positioning groove 12 is a T-shaped positioning groove. This not only facilitates the installation and positioning of the sealing strip, but also provides a very stable and reliable positioning effect for the sealing strip, thereby enabling it to perform a more stable and reliable sealing function. The shape of the positioning groove 12 is not limited to T-shape; other grooves used for mounting sealing strips are also within the protection scope of this utility model.

[0025] like Figure 1As shown, one side of the edge banding strip 1 is a right-angled portion 14 bent at 90 degrees towards its inner wall. The inner wall of the right-angled portion 14 (the inner wall of the right-angled portion 14 corresponds to the outer wall of the edge banding strip 1, and the outer wall of the right-angled portion 14 corresponds to the inner wall of the edge banding strip 1) forms a turning notch 11. This not only gives the edge banding strip 1 a simple structure but also creates a reliable turning notch 11, thereby better satisfying the need for the sealing strip on the door frame to adhere, and allowing the door stop strip on the door frame to be concealed by the turning notch 11. This, in turn, helps to give the door a more coordinated and reliable structure, avoiding abrupt structural changes on the door frame, which helps to improve the quality of home decoration.

[0026] like Figure 1 As shown, at least one reinforcing ridge 15 is provided on the inner wall of the edge banding strip 1. This reinforces the structural strength of the edge banding strip 1 by utilizing the reinforcing ridge 15. This achieves the dual purpose of controlling costs and ensuring structural strength while maintaining the strip structure of the edge banding strip 1, thereby helping to further improve the reliability and applicability of the door leaf edge banding strip.

[0027] like Figure 1 As shown, the positioning groove 12 and the turning notch 11 are located on both sides of the outer wall of the edge sealing strip 1; the reinforcing ridge 15 is located on the middle of the inner wall of the edge sealing strip 1. This allows the positioning groove 12 and the turning notch 11 to be far apart, thus allowing the two seals to be positioned far apart, which in turn facilitates a better sealing effect at the front and back of the gap between the door leaf and the door frame. This not only facilitates a better sealing effect but also effectively ensures that the edge sealing strip 1 has high structural strength, which helps to further improve the reliability and applicability of the door leaf edge sealing strip. Setting the reinforcing ridge 15 on the middle of the inner wall of the edge sealing strip 1 not only makes the structure of the door leaf edge sealing strip simple and coordinated but also ensures that the door leaf edge sealing strip has very reliable structural strength, which also helps to further improve the reliability and applicability of the door leaf edge sealing strip.

[0028] like Figure 1 As shown, the front and rear ends of the edge banding strip 1 are raised tapered surfaces 16. This facilitates the finishing of the paint at the edge banding strip 1 when making painted door panels with decorative paint applied to the surface, which not only improves the convenience of paint finishing but also improves the quality of paint finishing.

[0029] like Figure 1As shown, a positioning groove 17 is provided on the side of the tapered surface 16 near the inner wall of the edge sealing strip 1. The positioning groove 17 can be used to clamp the end of anti-crack mesh, anti-crack cloth or kraft paper and other anti-crack accessories for coating, or to provide anti-crack adhesive (structural adhesive, such as two-component polyurethane) for application. This can achieve the function of stabilizing the relevant anti-crack accessories or anti-crack adhesive by using the positioning groove 17, thereby facilitating a more stable and reliable anti-crack effect on the coating, and further helping to improve the reliability and applicability of the door edge sealing strip.

[0030] like Figure 1 As shown, the positioning groove 17 is a C-shaped groove, which facilitates a more stable and reliable positioning effect, thereby enabling a more stable and reliable crack-prevention effect. The shape of the positioning groove 17 is not limited to C-shape; other grooves used for mounting sealing strips are also within the protection scope of this utility model.

[0031] like Figure 1 As shown, to ensure sufficient width of the tapered surface 16 near the thickened portion 13, the thickened portion 13 can be extended to the side of the edge sealing strip 1, and the tapered surface 16 formed by the thickened portion 13 can be constructed. This allows the tapered surface 16 to have a wider width, which not only facilitates paint finishing and ensures finishing quality, but also provides sufficient opening space for the positioning groove 17, thus enabling the creation of a slightly wider positioning groove 17. This facilitates the installation of anti-crack fittings or anti-crack adhesive on the positioning groove 17, thereby improving the convenience of paint door manufacturing.

[0032] like Figure 1 As shown, to ensure sufficient width of the tapered surface 16 away from the thickened portion 13, a thickened strip 18 can be provided on the corresponding inner side of the edge sealing strip 1, and the tapered surface 16 is formed by the thickened strip 18. This allows the tapered surface 16 to have a wider width, which not only enhances the structural strength using the thickened strip 18, but also facilitates paint finishing and ensures finishing quality, and provides sufficient opening space for the positioning groove 17. This allows for the creation of a slightly wider positioning groove 17, which facilitates the installation of anti-crack fittings or anti-crack adhesive on the positioning groove 17, thereby improving the convenience of paint door manufacturing.

[0033] like Figure 1 As shown, the side of the tapered surface 16 near the outer wall of the edge banding strip 1 is a flat plane 161 that transitions smoothly with the outer wall of the edge banding strip 1, and the side of the tapered surface 16 near the inner wall of the edge banding strip 1 is an inclined surface 162 that slopes towards the outer wall of the edge banding strip 1. The positioning groove 17 is formed on the inclined surface 162. This not only facilitates the finishing of the paint but also helps to form a high-quality finish, thereby improving the manufacturing quality of the painted door leaf.

[0034] like Figure 1As shown, the plane 161 is connected to the top surface of the tapered surface 16 by a rounded transition, and the inclined surface 162 is also connected to the top surface of the tapered surface 16 by a rounded transition. This allows the tapered surface 16 to have a more harmonious and suitable structure, which not only facilitates the finishing and improves the finishing quality, but also helps to reduce bumps and knocks, thereby further improving the reliability and applicability of the door edge banding.

[0035] like Figure 1 As shown, at least one interlocking strip 19 is provided on the inner wall of the edge banding strip 1. This allows the edge banding strip to be positioned by inserting the interlocking strip 19 into the side wall of the door panel during installation. This not only improves the accuracy of the edge banding strip installation and positioning but also enhances the stability and reliability of the installation and positioning, thereby improving the quality of door assembly.

[0036] like Figure 1 As shown, the insert strip 19 is simultaneously connected to the thickened portion 13. This utilizes the thickened portion 13 to enhance the connection strength between the insert strip 19 and the edge sealing strip 1, thereby further improving the reliability and applicability of the door edge sealing strip.

[0037] like Figure 1 As shown, a connecting strip 19 and a reinforcing ridge 15 are also provided on the outer wall of the right-angle portion 14. This not only enhances the structural strength of the right-angle portion 14 with the reinforcing ridge 15, but also stably positions the right-angle portion 14 on the door panel with the connecting strip 19, which helps to further improve the reliability and applicability of the door panel sealing strip.

[0038] like Figure 1 As shown, the outer end of the insert strip 19 has a tapered head 190. This serves as a guide when inserting the insert strip 19, thereby improving the ease of insertion and, consequently, the ease of positioning the door panel edge banding.

[0039] like Figure 1 As shown, the surface of the insert strip 19 is provided with a plurality of barbed protrusions 191. This barbed protrusions 191 can play a stable anti-dislodgement role when the insert strip 19 is inserted, thereby helping to further improve the stability and reliability of the door leaf edge banding installation and positioning, and thus helping to further improve the reliability and applicability of the door leaf edge banding.

[0040] like Figure 1As shown, the edge banding strip 1 has a profile structure. The turning notch 11, positioning groove 12, thickened portion 13, right angle portion 14, reinforcing ridge 15, tapered end 16, positioning groove 17, flat surface 161, inclined surface 162, insert strip 19, conical head 190, barbed ridge 191, and thickened strip 18 are integrally formed with the edge banding strip 1. This not only improves the convenience and efficiency of mass production but also gives the door leaf edge banding strip a more stable and reliable structure, thereby helping to further improve the reliability and applicability of the door leaf edge banding strip. Example

[0041] like Figure 2 As shown, a door panel structure includes a door panel 10 and a door panel edge banding strip 20 as described in Embodiment 1. The door panel edge banding strip 20 is disposed on the side wall of the door panel 10.

[0042] This door panel structure, through the edge sealing strip 20, provides more reliable sound insulation and light blocking, thus offering users a better experience. Furthermore, this door panel structure is relatively simple and reliable, which not only facilitates manufacturing and reduces costs but also offers strong applicability.

[0043] like Figure 2 As shown, the door panel 10 can be either a single-layer board or a multi-layer board. When the door panel edge banding 20 has a right-angle portion 14, a clearance notch 101 is provided at the corner of the door panel 10 to accommodate the right-angle portion 14. The insert strip 19 is inserted into the side wall of the door panel 10, and the thickened portion 13, reinforcing ridge 15, and thickened strip 18 abut against the side wall of the door panel 10. This makes the assembly of the door panel edge banding 20 and the door panel 10 more coordinated and stable, thereby helping to further improve the assembly quality and durability of the door.

[0044] like Figure 2 and Figure 3 As shown, structural adhesive 30 is applied at the transition between the door panel 10 and the door edge banding strip 20, extending on both sides into the positioning groove 17 and onto the outer wall of the door panel 10. A decorative coating layer 40 is applied to the outer wall of the door panel 10, covering the structural adhesive 30 and the tapered end 16. This allows the structural adhesive 30 to stably connect the transition between the door panel 10 and the door edge banding strip 20, thus providing a stable crack-resistant effect and effectively preventing cracking at the ends of the decorative coating layer 40. This results in a highly reliable and durable coated door panel.

[0045] Adhesive can be applied to the insertion point of the insert strip 19, which helps to improve the stability and reliability of the insertion positioning. Adhesive can also be applied between the door leaf edge banding strip 20 and the side wall of the door leaf panel 10, which helps to improve the stability and reliability of the installation positioning of the door leaf edge banding strip 20.

[0046] like Figure 3 As shown, when this door leaf structure is used in conjunction with the door frame, a first sealing strip 50 is embedded in the positioning slot 12; a door stop 601 is provided on the door-joining surface of the door frame 60, and a second sealing strip 70 is pasted on the inner wall of the door stop 601; when the door is closed, the turning notch 11 covers the door stop 601, and the opening wall of the turning notch 11 is tightly pressed against the second sealing strip 70, while the first sealing strip 50 is tightly pressed against the door-joining surface of the door frame 60. This allows the first sealing strip 50 and the second sealing strip 70 to form two seals, and the cooperation between the turning notch 11 and the door stop 601 creates a turning point in the gap between the door leaf and the door frame, effectively improving the door's sound insulation and light-blocking performance, thus providing a better user experience.

[0047] like Figure 4 As shown, when there is no matching door stop strip at the bottom of the door leaf, it is not necessary to make a turning notch 11 and a right angle portion 14 on the door leaf edge banding. In this case, two positioning slots 12 are opened on the outer wall of the door leaf edge banding, and two thickened portions 13 are set on the inner wall of the door leaf edge banding. The two thickened portions 13 and the two positioning slots 12 are arranged side by side, inside and outside respectively. This can form a double seal on all four sides of the door leaf, thereby ensuring that the door has higher sound insulation and light-blocking performance, thus providing users with a better user experience.

[0048] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
