Description

Technical Field

[0001] The utility model relates to the field of door leaves, in particular to a door leaf frame assembly structure of a hanging board door leaf. Background Art

[0002] At present, in order to facilitate users to customize the decoration style, hanging panel door leaves have appeared. This type of hanging panel door leaf is composed of a door leaf frame and a decorative panel. The decorative panel can be detachably hung on the door leaf frame (for example: Chinese patent authorization announcement numbers CN221220240U, CN219864718U and CN219864713U and other patent documents disclosed). Among them, in order to avoid the overall thickness of the hanging panel door leaf being too large, it is now achieved by thinning the frame of the assembled door leaf frame. The thickness of the frame is generally less than 33mm. Since making a thin frame will affect the structural strength, the structural strength is generally improved by making the frame wider while making a thin frame. The width of the frame is generally made to be more than 175mm.

[0003] It can be seen that the frames of the door leaf frames assembled on the existing hanging board door leaves are mostly wide and thin frames. Although this can improve the structural strength, the thin thickness will still lead to limited structural strength of the frames, which will easily lead to limited bearing capacity and anti-deformation ability of the door and window frames; and this will also lead to a relatively large splicing width between adjacent frames, which is difficult to achieve reliable connection through traditional corner codes; so now it is generally necessary to fix the ends of adjacent frames together by welding. Since the splicing width between adjacent frames is relatively large, the amount of welding between adjacent frames will be relatively large. In addition, it takes time to accurately and stably attach adjacent frames together before welding to facilitate accurate welding, which will lead to low efficiency in splicing adjacent frames. At the same time, the existing window frame is generally assembled with four frames, so there are at least four splicing points that need to be welded. In this way, when the frames are welded, the assembly efficiency of the window frame will be very low, which greatly affects the assembly efficiency of the hanging board door leaf.

[0004] Therefore, it is very necessary to design a door leaf frame assembly structure for a hanging door leaf to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned problems and shortcomings and to provide a door leaf frame assembly structure for a hanging panel door leaf, which can facilitate the rapid and stable splicing of adjacent frames together, which not only ensures that the reliability of the splicing is very high, but also helps to greatly improve the efficiency of the door leaf frame assembly, thereby helping to improve the assembly efficiency of the hanging panel door leaf; and it can also help to improve the structural strength of the frame, thereby helping to improve the bearing capacity and anti-deformation ability of the door and window frame.

[0006] The technical solution of the utility model is achieved in this way:

[0007] A door leaf frame assembly structure for a hanging panel door leaf, characterized in that it includes two hollow frames and at least one angle code, wherein the frame wall of the hollow frame is recessed inward to form at least one groove portion, and the two ends of the angle code are respectively embedded in the end surfaces of the two hollow frames, and the groove portion is penetrated by at least one locking screw locked on the angle code.

[0008] Preferably, the front and rear frame walls of the hollow frame are both recessed inwards to form groove portions.

[0009] Preferably, there are two corner codes, and the ends of the two corner codes are respectively embedded in the end faces of the hollow frame corresponding to the two ends of the width direction of the hollow frame.

[0010] Preferably, a clearance groove is provided on the front wall and / or the rear wall of the hollow frame.

[0011] Preferably, at least one toothed surface is provided on the front wall and / or the rear wall of the hollow frame.

[0012] Preferably, a positioning slot is provided on the inner wall of the hollow frame.

[0013] Preferably, a storage groove is provided on the front wall of the hollow frame corresponding to the front of the positioning slot and / or on the rear wall corresponding to the rear of the positioning slot.

[0014] Preferably, the angle code is a hollow angle code, a positioning piece is provided on the inner wall of the angle code, a positioning strip with a C-shaped cross section is provided on the positioning piece, and the locking screw is locked on the inner wall of the positioning strip.

[0015] Preferably, two ends of the positioning piece are respectively connected to opposite inner walls of the angle code, and the positioning strip is located in the middle of the positioning piece.

[0016] Preferably, the end of the angle code is an embedded portion with a narrow outer end and a wide inner end.

[0017] The beneficial effects of the utility model are as follows: in the door leaf frame assembly structure, the use of the hollow frame can be beneficial to control the use of raw materials, thereby being beneficial to control the manufacturing cost. By making the frame wall of the hollow frame inwardly concave to form at least one groove portion, the groove portion can be used to make the hollow frame have a reinforced convex rib, thereby achieving the purpose of improving the structural strength of the hollow frame, and further being beneficial to improving the bearing capacity and anti-deformation capacity of the door leaf frame. By arranging at least one locking screw locked on the angle code on the groove portion, the hollow frame and the angle code can be fixed together more conveniently and stably, which can facilitate the rapid and stable assembly of adjacent frames together, and in this way, the insertion position of the locking screw can have a high structural strength, and the nut end of the locking screw can be conveniently hidden, which can facilitate the rapid and stable assembly of adjacent frames together, which can not only ensure that the reliability of the splicing is very high, but also greatly improve the efficiency of the door leaf frame assembly, thereby being beneficial to improving the assembly efficiency of the hanging board door leaf.

[0025] like Figures 1 to 5 As shown, the utility model describes a door leaf frame assembly structure for a hanging door leaf, comprising two hollow frame frames 1 and at least one corner code 2, wherein the frame wall of the hollow frame frame 1 is recessed inward to form at least one groove portion 11, and both ends of the corner code 2 are respectively embedded in the end surfaces of the two hollow frame frames 1, and at least one locking screw 3 locked on the corner code 2 is passed through the groove portion 11.

[0026] In the door leaf frame assembly structure, the use of a hollow frame 1 can help control the use of raw materials, thereby helping to control manufacturing costs. By making the frame wall of the hollow frame 1 inwardly concave to form at least one groove portion 11, the groove portion 11 can be used to make the hollow frame 1 have a reinforced convex rib, thereby achieving the purpose of improving the structural strength of the hollow frame 1, and further helping to improve the bearing capacity and anti-deformation capacity of the door leaf frame. By arranging at least one locking screw 3 locked on the angle code 2 on the groove portion 11, the hollow frame 1 can be conveniently and stably fixed to the angle code 2, which can help to quickly and stably assemble adjacent frames together, and in this way, the insertion position of the locking screw 3 can have a high structural strength, and the nut end of the locking screw 3 can be easily hidden, which can help to quickly and stably assemble adjacent frames together, which can not only ensure that the reliability of splicing is very high, but also help to greatly improve the efficiency of door leaf frame assembly, thereby helping to improve the assembly efficiency of the hanging board door leaf.

[0027] like Figure 5 As shown, the front and rear frame walls of the hollow frame 1 are both recessed inward to form a groove portion 11. This can further improve the structural strength of the hollow frame 1, thereby helping to further improve the reliability of the door leaf frame assembly structure. In addition, locking screws 3 can be arranged in front and behind the corner bracket 2 to fix the corner bracket 2 on the hollow frame 1, which can facilitate bidirectional locking, thereby further improving the reliability and applicability of the door leaf frame assembly structure.

[0028] like Figures 1 to 3 As shown, there are two corner brackets 2, and the ends of the two corner brackets 2 are respectively embedded in the end faces of the hollow frame 1 corresponding to the two ends of the width direction of the hollow frame 1. This can not only further improve the stability and reliability of the assembly of the hollow frame 1, but also eliminate the need to make the hollow frame 1 thicker, which is more suitable for use on the door leaf frame of the hanging door leaf, thereby helping to further improve the reliability and applicability of the door leaf frame assembly structure.

[0029] like Figure 5 As shown, at least two hollow cavities 20 are formed in the hollow frame 1 separated by the reinforcing sheet 10, which can not only help to improve the structural strength of the hollow frame 1, but also help to make the embedding of the corner code 2 more stable and reliable, thereby helping to further improve the stability and reliability of assembly.

[0030] like Figure 1 , Figure 4 and Figure 5 As shown, a clearance groove 12 is provided on the front wall and / or the rear wall of the hollow frame 1. The clearance groove 12 can provide a storage space for the hook assembly 30 for hanging the decorative panel, which can not only prevent the thickness of the hanging panel door leaf from being too large, but also facilitate the decorative panel to be closely attached to the door and window frame, thereby helping to further improve the applicability of the door and window frame assembly structure.

[0031] like Figure 4 and Figure 5 As shown, at least one toothed surface 13 is provided on the front wall and / or the rear wall of the hollow frame 1. This can help to make the decorative plate more closely and stably attached, thereby helping to further improve the applicability of the door leaf frame assembly structure.

[0032] like Figure 5 As shown, a positioning slot 14 is provided on the inner wall of the hollow frame 1. The positioning slot 14 can be used to clamp and position the sound insulation board, so as to form a stable and reliable sound insulation effect with the inner side of the door and window frame, thereby helping to further improve the applicability of the door leaf frame assembly structure.

[0033] like Figure 5 As shown, a storage groove 15 is provided on the front wall of the hollow frame 1 in front of the corresponding positioning slot 14 and / or on the rear wall in the rear of the corresponding positioning slot 14. When the sound insulation board is fixed by screws, the nut end of the screw can be hidden by the storage groove 15 to avoid the nut end of the screw protruding outside, which can help the hanging board door leaf have a very compact and reliable structure.

[0034] like Figure 2 , Figure 3 and Figure 6 As shown, the corner bracket 2 is a hollow corner bracket, a positioning piece 21 is provided on the inner wall of the corner bracket 2, a positioning strip 22 with a C-shaped cross section is provided on the positioning piece 21, and the locking screw 3 is locked on the inner wall of the positioning strip 22. This can not only control the use of raw materials on the corner bracket 2, but also ensure that the corner bracket 2 has a high structural strength, and can help the locking screw 3 to achieve stable locking; and even if there is an opening error in the hole for the locking screw 3 to pass through on the hollow frame 1 or a processing error in the corner bracket, it can also help to ensure that the locking screw 3 is effectively locked, and avoid the situation where the locking of the locking screw 3 causes the corner bracket 2 to crack, thereby helping to further improve the reliability and applicability of the door frame assembly structure.

[0035] like Figure 2 , Figure 3 and Figure 6 As shown, the number of the positioning pieces 21 and the positioning strips 22 increases as the number of the locking screws 3 increases, so that a reliable locking position can be provided for each locking screw 3, thereby meeting the actual assembly requirements.

[0036] like Figure 6As shown, the two ends of the positioning piece 21 are respectively connected to the opposite inner walls of the angle bracket 2, and the positioning strip 22 is located in the middle of the positioning piece 21. This can not only enhance the structural strength of the angle bracket 2, but also make the positioning strip 22 have a more stable and reliable positioning function, thereby helping to further improve the reliability and applicability of the door frame assembly structure.

[0037] like Figure 6 As shown, the end of the corner code 2 is an embedding portion 23 with a narrow outer end and a wide inner end. This can facilitate the embedding of the end of the corner code 2 into the hollow frame 1, thereby helping to improve the convenience of assembly.

[0038] like Figure 7 As shown, in the actual manufacturing process, four hollow frames 1 can be used to enclose a rectangular door leaf frame 100, and adjacent hollow frames 1 can be fixed together by angle codes 2 and locking screws 3, so that a stable and reliable door leaf frame 100 can be formed, thereby meeting the use requirements of the hanging panel door leaf.

[0039] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
