Description

Technical Field

[0001] The utility model relates to the field of doors and windows, in particular to an outer frame structure of doors and windows. Background Art

[0002] At present, in order to fix the door and window outer frames on the wall, most of the door and window fixing plates and screws are used to fix the door and window outer frames. The specific assembly structure is that the door and window fixing plates are embedded in the door and window outer frames, and the door and window fixing plates are fixed to the wall by screws (for example: disclosed in the patent document of China's authorization announcement number CN202324997U). Since the door and window fixing plates are sheet-like structures, this will not only lead to limited embedding strength between the door and window fixing plates and the door and window outer frames, but also lead to limited structural strength at the screw locking point, which can easily lead to limited installation and positioning strength of the door and window outer frames. When the doors and windows encounter a large impact or strong wind, it is easy to cause the door and window outer frames to become loose at the embedding point between the door and window fixing plates and / or the locking point of the screws, which can easily affect the safety and service life of the doors and windows. Therefore, it is very necessary to redesign the structure of the door and window outer frames. Utility Model Content

[0020] like Figure 1 As shown, a door and window outer frame structure described in the utility model includes an outer frame body 1, a reinforcing steel bar 2, and a plurality of locking screws 3, wherein a positioning slot 11 is opened on the outer frame body 1, the reinforcing steel bar 2 is embedded in the positioning slot 11, and each locking screw 3 is arranged on the outer frame body 1 or the reinforcing steel bar 2, and the threaded end of the locking screw 3 passes through the reinforcing steel bar 2 and is placed outside the positioning slot 11.

[0021] In the structure of the outer frame of the door and window, a reinforcing steel bar 2 is used, and the reinforcing steel bar 2 is embedded in the positioning slot 11 on the outer frame body 1. After each locking screw 3 is arranged on the outer frame body 1 or the reinforcing steel bar 2, the threaded end of the locking screw 3 is passed through the reinforcing steel bar 2 and then placed outside the positioning slot 11. This can not only ensure that the assembly of the reinforcing steel bar 2 and the outer frame body 1 has a high structural strength, but also greatly enhance the structural strength of the locking screw 3 through the insertion point, which can help to enhance the structural strength of the installation and positioning of the outer frame of the door and window, thereby greatly improving the ability of the door and window to resist large impacts and strong winds, and further greatly reducing the probability of the outer frame of the door and window being loose, which can help to improve the safety of the use of the door and window and extend the service life.

[0022] like Figure 1 and Figure 4 As shown, the positioning slot 11 is a T-shaped slot. The reinforcing steel bar 2 is tightly embedded in the positioning slot 11, which can further enhance the stability and reliability of the assembly of the reinforcing steel bar 2 and the outer frame body 1; and when the locking screw 3 is locked, the force of the reinforcing steel bar 2 on the outer frame body 1 can be more uniform and stable, thereby helping to further improve the reliability of the door and window outer frame structure.

[0023] like Figure 1 and Figure 4 As shown, the positioning card slot 11 is located on the bottom surface of the outer frame body 1, a storage cavity 12 is provided in the middle of the outer frame body 1, a penetration hole 13 penetrating to the storage cavity 12 is provided in the middle of the top surface of the outer frame body 1, and a clearance hole 14 penetrating to the positioning card slot 11 is provided at the bottom of the storage cavity 12. The locking screw 3 is penetrated through the penetration hole 13 and arranged in the storage cavity 12, and the threaded end of the locking screw 3 is downwardly passed through the clearance hole 14 and the reinforcing steel bar 2 in sequence. This not only facilitates the installation and positioning of the locking screw 3, but also achieves the purpose of hiding the locking screw 3, thereby providing a certain shielding and protection effect on the locking screw 3, which can further improve the convenience and stability of the installation and positioning of the door and window outer frame structure.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, a sealing rubber plug 4 is embedded in the penetration hole 13. In this way, the locking screw 3 can be completely hidden, thereby further reducing the aging speed of the locking screw 3, and then facilitating the disassembly and maintenance of the door and window outer frame structure at a later stage.

[0025] The number of the penetration holes 13 and the number of the clearance holes 14 are equal to the number of the locking screws 3, and a sealing rubber plug 4 is embedded in the opening of each penetration hole 13; the nut end of the locking screw 3 can be pressed tightly against the bottom of the inner cavity 12, and can also be pressed tightly against the top surface of the reinforcing steel bar 2. In this way, the actual installation and positioning requirements can be well met.

[0026] like Figure 1 As shown, the reinforcing steel bar 2 is a rectangular stainless steel bar, the thickness H of the reinforcing steel bar 2 is greater than 10 mm, and the width D of the reinforcing steel bar 2 is greater than 15 mm. In this way, the reinforcing steel bar 2 has very strong structural strength and durability, thereby helping to further improve the reliability of the door and window outer frame structure.

[0027] like Figure 1 As shown, a covering convex ring 41 is integrally formed on the outer circumferential surface of the sealing rubber plug 4, and the covering convex ring 41 is tightly pressed on the top surface of the outer frame body 1. This not only facilitates the rapid and accurate installation of the sealing rubber plug 4, but also further improves the sealing performance.

[0028] like Figure 4 As shown, a blocking piece 15 is provided on the outer edge of the top surface of the outer frame body 1, and a first convex strip 16 is provided on the inner surface of the blocking piece 15, and a first T-shaped card slot 161 is provided on the first convex strip 16. The first convex strip 16 is provided so that the opening of the first T-shaped card slot 161 has high structural strength. The first T-shaped card slot 161 can be embedded with a sealing strip, and the blocking piece 15 can block the door and window sashes, which can make the door and window outer frame structure better meet the needs of actual use, thereby helping to further improve the applicability of the door and window outer frame structure.

[0029] like Figures 2 to 4 As shown, an inner hole 17 is provided on the outer end of the outer frame body 1, a water receiving groove 18 is provided on the outer end of the top surface of the outer frame body 1, at least one drain hole 181 penetrating into the inner hole 17 is provided at the bottom of the water receiving groove 18, and at least one drainage hole 171 penetrating into the inner hole 17 is provided on the outer wall of the outer frame body 1. In this way, when the sealing strip on the first T-shaped card groove 161 loses its waterproof function, rainwater can be discharged to the outside through the water receiving groove 18, the drain hole 181, the inner hole 17, and the drainage hole 171, thereby helping to further improve the waterproof performance of the door and window outer frame structure.

[0030] like Figure 4 As shown, a second convex strip 19 is provided on the inner end of the top surface of the outer frame body 1, and a second T-shaped card slot 191 is provided on the second convex strip 19. The second convex strip 19 can ensure that the opening of the second T-shaped card slot 191 has high structural strength; the second T-shaped card slot 191 can be embedded with a sealing strip, which can help to further improve the sealing performance when the door and window are closed.

[0031] like Figures 1 to 3 As shown, a sealing rubber pad 5 is arranged on the surface of the reinforcing steel bar 2 facing the notch of the positioning slot 11, and the outer wall of the sealing rubber pad 5 protrudes out of the positioning slot 11. The sealing rubber pad 5 is used to be close to the wall, which can help improve the sealing performance of the installation and positioning of the door and window outer frame structure, thereby helping to further improve the applicability of the door and window outer frame structure.

[0032] The sealing rubber pad 5 is a soft rubber sheet, and the sealing rubber pad 5 is fixed on the reinforcing steel bar 2 by gluing, so that the requirement of stably installing the sealing rubber pad 5 can be achieved.

[0033] like Figure 1 As shown, the locking screw 3 is an expansion screw, which can help improve the stability and reliability of the locking of the locking screw 3, thereby helping to further improve the reliability of the door and window outer frame structure.

[0034] like Figure 5 As shown, in the actual installation process, the locking screw 3 is locked on the wall 10; the gap between the outer frame body 1 and the wall 10 is filled with the sealant 20, and pressure is applied to the sealant 20 before it solidifies (two strips can be used to squeeze the sealant 20 inside and outside the outer frame body 1 respectively, so that the sealant 20 can be pressed), so that the sealant 20 produces pressure to press the sealant pad 5, so that the sealant pad 5 shrinks and deforms. After the sealant 20 solidifies, the two strips are loosened, which can make the sealant pad 5 elastically act on the sealant 20, thereby ensuring that the sealing performance maintains high stability for a long time. In the actual installation process, the sealant pad 5 can also be directly pressed on the wall 10, which can also play a very good sealing effect.
