Description

A New Corner Connection Structure of Aluminum Alloy Doors and Windows

technical field

The utility model relates to a corner connection structure of a door and window fan, in particular to the corner connection structure of a broken bridge aluminum alloy door and window fan.

Background technique

At present, there are mainly three types of connection methods for the corners of broken bridge aluminum alloy doors and windows on the market, namely, 45° angle impact angle process connection, 90° angle screw connection, and ordinary corner code connection. The 45° impact angle process connection is the most commonly used form, but it cannot be used when there is no separate cavity in the aluminum alloy part of the enlarged profile of the heat insulation strip. The 90° angle screw connection is not beautiful, and the sealing effect is poor. Ordinary corner code connection sealing effect is poor. With the improvement of people's daily life, the performance requirements of doors and windows are getting higher and higher. It is a consensus in the industry to improve the "three characteristics" of doors and windows.

Utility model content

The technical problem solved by the utility model is to provide a connection structure for the corners of door and window sash which can solve the above-mentioned defects.

The technical means adopted in the utility model are as follows. A new type of aluminum alloy door and window corner connection structure. The connection between two adjacent profiles is cut at a 45° angle. There are two heat-insulating strips in the middle of the profiles. In the accommodation space between the two insulation strips, one side of the corner bracket is provided with a mounting hole through the corner bracket, and the bottom of the other side of the corner bracket is also cut at a 45° angle, and two adjacent corner brackets are connected to each other; two heat insulation strips A concentric through hole is provided, the position of the through hole matches the mounting hole, and the pin passes through the through hole and the mounting hole to fix the corner code and the profile.

A second installation hole is provided on the slope adjacent to the two corners, and the screw passes through the second installation hole to connect the two corners. One end of the screw is connected with a nut; the outer heat insulation strip is provided with a second through hole, and the position of the second through hole is the same as that of the second through hole. The second mounting holes are matched, and the second through holes of two adjacent profiles allow screws and nuts to enter.

There is a glue injection channel on the inner surface of the corner code, and the glue injection channel extends to the bottom of the 45° angle of the corner code cutting; the corresponding position of the profile and the glue injection channel is provided with a glue injection hole.

The pins are knurled and fixed to the profile by a transition fit.

The beneficial effects of the utility model are: the connection structure of the utility model is easy to install, and the connection is tight; moreover, the inner corner of the profile is provided with a glue injection hole, and the corner code is provided with a glue injection flow channel, and the glue is injected through the glue injection hole. The glue injection flow channel spreads all over the joints of the corners, so that the joints of the profile corners form an effective seal, achieving the effect of preventing water seepage and releasing air leakage, and improving the watertightness, airtightness and heat preservation of the window.

Detailed ways

Please refer to Figure 1-2, a new type of aluminum alloy door and window corner connection structure. The joint between two adjacent profiles 1 is cut at a 45° angle. The space between them is the accommodation space, and the key point is that the corner bracket 3 is accommodated in the accommodation space between two heat-insulation strips 11, and one side of the corner bracket 3 is provided with a mounting hole 31 passing through the corner bracket, and the installation hole is generally round. hole. The bottom of the other side of the corner code 3 is also cut at a 45° angle, and two adjacent corner codes 3 are connected to each other.

The two heat insulating strips 11 are provided with concentric through-holes 12 , the positions of the through-holes 12 match the installation holes 31 , and the shapes generally also match. The pin 2 passes through the through hole 12 and the mounting hole 31 to fix the corner bracket 3 and the profile 1 . The pin 2 can be a knurled structure, fixed with the profile through a transition fit.

The second mounting hole 32 is provided on the inclined surface adjacent to the two corners 3, and the screw 4 passes through the second mounting hole 32 to connect the two corners 3. The screw 4 is generally a hexagon socket screw, and one end of the screw 4 is connected with a nut 5; the outer side is insulated The bar 11 is provided with a second through hole 13, and the second through hole 13 is generally a long hole or an oval hole. The position of the second through hole 13 is matched with the second installation hole 31 , and the second through holes 13 of two adjacent profiles allow the screw 4 and the nut 5 to enter respectively.

In addition, the inner surface of the corner code 3 is provided with a glue injection flow channel 7, and the glue injection flow channel 7 extends to the bottom of the corner code 3 cut at a 45° angle; the profile 1 is provided with a glue injection hole 6 corresponding to the glue injection flow channel 7. In the figure of this embodiment, the glue injection hole 6 is set at the bottom position below the heat insulation strip inside the profile. The glue is injected from the glue injection hole through the glue injection flow channel to spread all over the joints of the corners, so that the corners of the profiles can be connected to form an effective seal, so as to achieve the effect of preventing water seepage and air leakage, and improving the watertightness, airtightness and heat preservation of the window sex.
