Description

Technical Field

[0001] The utility model relates to a door and window frame corner bracket, in particular to a door and window frame corner bracket with a novel corner protection structure. Background Art

[0002] When making door and window frames, angle brackets are often used to assemble various profiles. When users use these assembled doors and windows, they find that the corners of the doors and windows are too sharp and are easily damaged by bumps during daily use.

[0003] In response to the above problems, designers in related fields have set up protective corners with good buffering performance at the corners of existing corner brackets. The frame assembled using such corner brackets can effectively reduce the damage caused by bumps at the corners, especially for inward-opening windows, which can effectively reduce the collision damage at the corners of inward-opening windows. However, in actual use, it is found that such corner brackets with protective corners are prone to breakage after being used for a period of time. This is specifically caused by the structural design of the existing protective corners. The existing protective corners are composed of an end with a chamfered surface and a snap-fitting portion connecting the end to the corner bracket. There is a necking structure at the connection between the end and the snap-fitting portion, and there is stress concentration at the necking portion. After the protective corner has been used for a period of time, the elastic material ages. At this time, if the protective corner is frequently collided, the necked portion may gradually break. Therefore, it is necessary to propose a new corner protection structure to solve the above problems. Utility Model Content

[0023] See also Figure 1 , Figure 2 and Figure 4 In a preferred embodiment of the present application, a corner code for connecting adjacent profiles 200 and assembling them into a door and window frame is provided, and the corner code is suitable for profiles 200 with profile grooves 210 on the end surface. The corner code includes a corner protector 100, and the corner protector 100 includes two connecting members 110 arranged in the same plane 400 and both adapted to the profile grooves 210 on the frame. The two connecting members 110 are arranged perpendicular to each other, and one end of the two connecting members 110 extends to the same inclined plane 500 to intersect to form an end angle 120. The end angle 120 has an outer angle 121 when viewed along the plane 400. An anti-collision component 300 is provided at the end of the outer angle 121. The anti-collision component 300 includes a roller 320. The roller 320 is restricted to rotate at the end of the outer corner 121, and the rotating surface 600 of the roller 320 is parallel to the plane 400. After the adjacent profiles 200 constituting the frame are connected by the corner guard 100, the adjacent profiles 200 constituting the frame are perpendicular to each other and intersect, and the size of the roller 320 is configured so that the peripheral side of the roller 320 protrudes from the surface of the profile 200 constituting the frame, so as to form a protection for the corner tip of the door and window frame and reduce the damage caused by bumps at the corner of the door and window frame. It should be noted that the material selected for the roller 320 is not specifically limited, but it must have good buffering performance.

[0024] Specifically, the connecting member 110 has a first side component 111 and a second side component 112 when viewed along the plane 400. The first side component 111 and the second side component 112 are both bar-shaped metal members. The first side component 111 and the second side component 112 are arranged in parallel, that is, the surfaces of the two bar-shaped metal members formed by the length direction and the width direction are arranged in parallel with each other, and the other corresponding side surfaces are in a flush state. The first side component 111 and the second side component 112 are connected by a first support member 113. The first support member 113 is also made of metal, connecting the first side component 111 and the second side component 112 as a whole. An air groove 130 is constructed on the side component 111 and / or the second side component 112. The air groove 130 is a concave groove body extending along the width direction of the strip metal part. The length of the air groove 130 is equal to the width of the strip metal part. During the process of inserting the connecting member 110 into the profile groove 210, the gas in the profile groove 210 is squeezed by the connecting member 110 and will be discharged from the gap between the side surface of the first side component 111 and the inner wall of the profile groove 210 and / or the gap between the side surface of the second side component 112 and the inner wall of the profile groove 210. The air groove 130 makes the gas discharge smoother and reduces the resistance of the connecting member 110 to the insertion of the profile groove 210. Furthermore, the corner protector 100 is provided with a second support member 114 at the connection end of the two connecting members 110, the ends of the first side components 111 in the two connecting members 110 are connected to form an outer angle 121, and the ends of the second side components 112 in the two connecting members 110 are connected to form an inner angle 122. The second support member 114 is a sheet metal plate, and the second support member 114 connects the outer angle 121 and the inner angle 122, thereby enhancing the connection strength and overall strength between the two connecting members 110. The two connecting members 110 are connected after extending to the inclined surface 500, and the angle between the inclined surface 500 and the first side component 111 and the angle between the inclined surface 500 and the second side component 112 are both 45 degrees. It should be noted that the profile 200 adapted to the corner protector 100 in the present application, in addition to having a profile groove 210, should also have an end with an inclination angle of 45 degrees to facilitate splicing between adjacent profiles 200. It should be noted that the plane 400 refers to a plane parallel to a plane formed by the width direction and the thickness direction of the profile 200 .

[0025] For further information, see Figure 5-6The anti-collision component 300 also includes a mounting member 310 arranged at the end of the outer corner 121, and a cylindrical groove 311 for mounting the roller 320 is constructed on the mounting member 310, and the axis of the cylindrical groove 311 is perpendicular to the plane 400, and the mounting member 310 is constructed with a notch 312 on the side away from the outer corner 121 to communicate with the cylindrical groove 311 so that the peripheral side of the roller 320 is partially exposed, and the cylindrical groove 311 has a first arc when observed along the plane 400, and the radius of the first arc is equal to the radius of the roller 320, and the arc length of the notch section of the first arc is less than half of the circumference of the full circle corresponding to the radius of the first arc, so as to prevent the roller 320 from escaping from the cylindrical groove 311, so that the roller 320 can only roll in the cylindrical groove 311, so that it can roll when the corner of the door and window frame is hit to relieve the impact generated by the collision.

[0026] Specifically, the mounting member 310 is composed of an inverted "T"-shaped snap-fit ​​structure and a rectangular structure located at the end of the inverted "T" shape when observed along the cross section. The inverted "T"-shaped snap-fit ​​structure and the rectangular structure extend in a direction perpendicular to the cross section to form the mounting member 310. A mounting groove 1211 is constructed at the end of the outer corner 121. The cross-sectional shape of the mounting groove 1211 is adapted to the cross-sectional shape of the mounting member 310. The extension direction of the mounting groove 1211 is perpendicular to the direction of the plane 400. The mounting member 310 is detachably connected to the mounting groove 1211. When the mounting member 310 is installed in the mounting groove 1211, both ends of the mounting member 310 are flush with the surface of the corner guard 100.

[0027] In order to prevent the roller 320 from detaching from the two ends of the cylindrical groove 311, it is necessary to construct a limiting structure 313 at both ends of the cylindrical groove 311, and the spacing between the limiting structures 313 located at both ends of the cylindrical groove 311 should be adapted to the length of the roller 320, so that the two ends of the roller 320 are respectively fitted and connected with the corresponding limiting structures 313 to prevent the roller 320 from moving in the cylindrical groove 311.

[0028] See also Figure 2-3 After the adjacent profiles 200 on the frame are connected together by the corner protectors 100, the adjacent profiles 200 are perpendicular to each other. In order to improve the integrity of the frame and prevent the profiles 200 from detaching from the corner protectors 100, pressing teeth 314 can be constructed on both sides of the mounting member 310. After the adjacent profiles 200 are installed on the corner protectors 100, the positions on the profiles 200 corresponding to the pressing teeth 314 are constructed with tooth grooves 220 for the pressing teeth 314 to engage with. When the pressing teeth 314 are connected to the tooth grooves 220 on the profiles 200, one side of the tooth grooves 220 abuts against the inner wall of one side of the tooth grooves 220, and a pulling force directed to the mounting member 310 is applied to the profiles 200 to pull the profiles 200 on both sides toward the corner protectors 100, thereby improving the connection strength between the profiles and the corner protectors 100, thereby enhancing the integrity of the door and window frames.
