Description

Technical Field

[0001] The utility model relates to the field of doors and windows, and in particular to a novel groove-free glue-injected stile connector structure. Background Art

[0002] When using profiles to assemble doors and windows, there are usually connections between profiles, such as the connection between muntins and muntins or the connection between frames and muntins. The profiles used to make doors and windows generally include an indoor cavity and an outdoor cavity, which are connected as a whole by a thermal insulation profile in the middle. Mullion-mullion connection or frame-mullion connection is achieved through muntin connectors.

[0003] The muntin is a horizontal or vertical division of the window frame. In order to meet the different requirements of door and window partitions, the muntin and frame of aluminum alloy doors and windows need to be connected. Some of the current connection methods are too complicated, not only inefficient and costly, but also have low connection strength, which is easy to loosen and twist, affecting the quality of doors and windows.

[0004] At present, for the common aluminum alloy doors and windows on the market, especially the strip-type thermal insulation aluminum alloy doors and windows, when installing the center beam, process connection holes must be opened at the corresponding positions on both sides of the window frame side walls to be connected, and holes must also be drilled and tapped on the center beam connector. When connecting the center beam, it is connected to the center beam connector through the process hole by screws. The drilling position of the process hole and the hole position accuracy of the center beam connector are high. The quality of the center beam connection is difficult to control. Once one of the hole positions has a deviation, it will affect the dimensional accuracy after connection, especially when the cross connection is difficult to handle.

[0005] In addition, the existing stile connectors need to be grooved and poured when pouring glue, and the stile connectors after the grooves are cut will affect the stability and strength of the structure, thereby affecting the stability of the doors and windows. Utility Model Content

[0007] The purpose of the utility model is achieved through the following technical measures: a novel groove-free glue-injected stile connector structure, characterized in that: it includes a connector body, the connector body is integrally arranged, one end of the connector body is a profile clamping part, and the other end of the connector body is a profile plug-in part, the profile plug-in part is provided with a pin oblong hole, the profile clamping part is provided with a glue injection hole, the profile clamping part is provided with a glue injection channel, the glue injection channel separates the profile clamping part into a first clamping claw and a second clamping claw, the first clamping claw and the second clamping claw are clamped with a main profile, the part of the profile plug-in part close to the profile clamping part is provided with a top screw mounting hole, the top screw mounting hole is used to install a tightening screw, a partition is integrally arranged between the profile clamping part and the profile plug-in part, when in use, the tightening screw passes through the partition and is pressed between the first clamping claw and the second clamping claw, and the tightening screw pushes the first clamping claw and the second clamping claw to both sides of the glue injection channel for clamping the main profile.

[0008] As a preferred solution: the main profile includes a first main body and a second main body, a heat insulating connector is provided between the first main body and the second main body, and the heat insulating connector is used to connect the first main body and the second main body.

[0009] As a preferred solution: a first glue-receiving section is provided at one end of the first clamping claw close to the second clamping claw and away from the glue injection hole, and a second glue-receiving section is provided at one end of the second clamping claw close to the first clamping claw and away from the glue injection hole.

[0010] As a preferred solution: a clamping groove is provided at one end of the first body close to the first clamping claw and the second clamping claw, and the first clamping claw and the second clamping claw are clamped in the clamping groove.

[0020] Example: As shown in the attached Figure 1 and attached Figure 2 As shown, a novel groove-free glue-injected stile connector structure comprises a connector body, the connector body is integrated, one end of the connector body is a profile clamping part 1, the other end of the connector body is a profile plug-in part 2, the profile plug-in part 2 is provided with a pin oblong hole 3, the profile clamping part 1 is provided with a glue injection hole 4, the profile clamping part 1 is provided with a glue injection channel 5, the glue injection channel 5 separates the profile clamping part 1 into a first clamping claw 6 and a second clamping claw 7, the first A clamping claw 6 and a second clamping claw 7 are clamped with a main profile 11, and a top screw mounting hole 8 is opened at the part of the profile plug-in part 2 close to the profile clamping part 1, and the top screw mounting hole 8 is used to install a tightening screw 9. A partition 10 is integrally arranged between the profile clamping part 1 and the profile plug-in part 2. When in use, the tightening screw 9 passes through the partition 10 and is pressed between the first clamping claw 6 and the second clamping claw 7. The tightening screw 9 pushes the first clamping claw 6 and the second clamping claw 7 to both sides of the glue injection channel 5 to clamp the main profile 11.

[0021] As attached Figure 3 and attached Figure 4 As shown, the main profile 11 includes a first main body 111 and a second main body 112 , and a heat insulating connector 113 is provided between the first main body 111 and the second main body 112 . The heat insulating connector 113 is used to connect the first main body 111 and the second main body 112 .

[0022] A first glue-receiving section 61 is formed at one end of the first clamping claw 6 close to the second clamping claw 7 and away from the glue injection hole 4 , and a second glue-receiving section 71 is formed at one end of the second clamping claw 7 close to the first clamping claw 6 and away from the glue injection hole 4 .

[0023] A clamping groove 114 is provided at one end of the first body 111 close to the first clamping claw 6 and the second clamping claw 7 , and the first clamping claw 6 and the second clamping claw 7 are clamped in the clamping groove 114 .

[0024] As attached Figure 5 As shown, a glue holding space 12 is formed between the first glue holding section 61, the second glue holding section 71 and the first body 111. When injecting glue, the two-component glue enters the glue injection channel 5 through the glue injection hole 4 and then enters the glue holding space 12, which can increase the strength of the connection and improve the sealing.

[0025] As attached Figure 4 As shown, the thermal insulation connector 113 includes a first connector 1131 and a second connector 1132 , a thermal insulation block 1133 is disposed between the first connector 1131 and the second connector 1132 , and the thermal insulation block 1133 is fixedly connected between the first connector 1131 and the second connector 1132 .

[0026] From the above content, it can be known that the present application discloses a groove-free, glue-injected stile connector structure with efficient connection and enhanced sealing, which is mainly used in frame structures constructed of doors, windows or other profiles to ensure a tight connection between profiles and provide good thermal insulation and sealing performance.

[0027] First, the connector body is an integrally manufactured component with specific functional designs at both ends. One end is the profile clamping part 1, which is mainly responsible for docking and fixing with the main profile 11. A glue injection hole 4 is provided inside the profile clamping part 1, which serves as an entrance for injecting two-component glue. The glue injection hole 4 is connected to the glue injection channel 5, and the glue injection channel 5 cleverly divides the profile clamping part into a first clamping claw 6 and a second clamping claw 7 that are symmetrical to each other. These two clamping claws respectively cooperate with the clamping groove 114 on the main profile 11 to achieve mechanical clamping.

[0028] The other end is a profile plug-in portion 2, which is equipped with an oblong pin hole 3 to facilitate positioning or connection with adjacent components by inserting a pin. A top screw installation hole 8 is set at a position of the profile plug-in portion 2 close to the profile clamping portion 1, where a tightening screw 9 can be installed. The tightening screw 9 passes through a partition 10 pre-set between the profile clamping portion and the plug-in portion. When the tightening screw 9 is tightened, the first claw 6 and the second claw 7 can be pushed to expand along both sides of the glue injection channel 5, thereby tightly clamping the main profile 11 and enhancing the stability of the connection.

[0029] In terms of specific connection details, the first clamping claw 6 and the second clamping claw 7 are respectively provided with a first glue containing section 61 and a second glue containing section 71 at one end away from the glue injection hole 4. After the two glue containing sections are connected with the main profile 11, they jointly form a glue containing space 12 for containing two-component glue. When the glue is injected through the glue injection hole 4, the glue fills the glue containing space 12 through the glue injection channel 5, which not only improves the overall strength of the connection part, but also greatly enhances the air tightness and waterproofness of the connection.

[0030] At the same time, the main profile 11 is composed of a first main body 111 and a second main body 112, which are connected by a heat-insulating connector 113. The heat-insulating connector 113 is composed of a first connector 1131 and a second connector 1132 with a heat-insulating block 1133 embedded in the middle. The heat-insulating block 1133 ensures effective heat insulation between the first main body and the second main body, prevents heat transfer, and improves the thermal insulation effect of the entire frame structure.

[0031] In summary, this application achieves a firm connection between profiles, efficient sealing and good thermal insulation performance through integrated design, glue injection reinforced connection and integrated thermal insulation structure, which significantly improves the quality and durability of building doors and windows and other frame structures.
