Description

Technical Field

[0001] The utility model belongs to the technical field of doors and windows, and particularly relates to a corner block for connecting the corners of door and window frames. Background Art

[0002] The corner connection of the door and window frame is a relatively weak link in sealing, which easily leads to water vapor and air infiltration into the room. During the use of the door and window frame, due to factors such as temperature changes and vibration, the screws may gradually loosen, affecting the sealing and stability of the door and window. The traditional door and window frame corner connection may only rely on screw connection, and the screws are prone to loosening after long-term use, resulting in a decrease in connection strength. Therefore, it is necessary to propose a corner block for the door and window frame corner connection to improve the strength and sealing of the connection between the corner block and the frame. Utility Model Content

[0003] In order to solve the above technical problems, the utility model proposes a corner block for connecting the corners of door and window frames, aiming to solve or improve at least one of the above technical problems.

[0004] To achieve the above-mentioned purpose, the utility model provides a corner block for connecting the corners of door and window frames, wherein the corner block is L-shaped, having a horizontal end and a vertical end, a threaded hole is formed on the outer side surface of at least one of the horizontal end and the vertical end, and a conducting cavity with a hole diameter larger than that of the threaded hole is formed at the bottom of the threaded hole, the conducting cavity is connected to a glue inlet and a glue outlet, and the glue outlet is connected to a side glue groove located on at least one side of the corner block.

[0005] The above structure aims to provide a corner block that can increase the connection strength of the window frame corner by gluing. The screws are sealed by the colloid to prevent the screws from loosening after long-term use. At the same time, it can achieve a sealing effect. The side glue grooves on the side of the corner block are filled with glue by the colloid to form a tighter connection between the side of the corner block and the internal cavity of the door and window frame, thereby increasing the connection strength.

[0006] Preferably, the glue inlet is connected to the glue pouring channel, and the glue pouring channel is connected to the glue pouring port on the outer side of the corner block. When the corner block is installed in place, the screw is screwed in first, and then the glue is injected into the glue pouring port. The glue enters through the glue pouring channel, enters the conduction cavity along the glue pouring channel, and then enters the side glue application groove. When the glue is poured, the glue pouring port is sealed with a sealing cover, and the glue application is simple and fast.

[0007] Preferably, the glue inlet is connected to a glue storage chamber, a glue bag is pre-placed in the glue storage chamber, one end of the glue bag passes through the glue inlet into the conduction cavity, and is punctured when the screw is screwed in, thereby dispensing the glue. The glue storage chamber is arranged inside the corner block, and there is no need to perform glue filling operation after installation, which saves time and effort in installation. The glue bag is punctured by the screwed-in screw, and the glue flows out automatically, completing the glue application.

[0008] Preferably, an elastic push piece is provided at the bottom of the glue storage chamber, and the elastic push piece is compressed at the bottom of the plastic bag in the initial state. The corner block provided with the elastic push piece can complete the glue application more quickly without causing the waste of glue, and can fully push out the glue in the first glue chamber and the second glue chamber.

[0009] Preferably, the corner block is a split structure, including two side panels that are buckled together. The colloid can be pre-installed in a plastic bag integrally formed with the sealing film, and directly placed in the glue storage chamber. At the same time, the two sealing films are extended out of the glue inlet and then buckled to connect the two side panels.

[0010] Preferably, the corner block is integrally formed. The integrally formed corner block has the advantages of simpler structure, lower manufacturing cost and higher structural strength.

[0011] Preferably, the corner block is made of metal, preferably a steel structure or an aluminum alloy structure.

[0012] Preferably, a tooth-like structure is provided on the inner side surface of the corner block, and the tooth-like structure is used to abut against the cavity of the door and window frame when the corner block is inserted into the door and window frame. The tooth-like structure can increase the connection strength.

[0013] The corner block for connecting the corners of door and window frames of the utility model has the beneficial effects of simple structure, high connection strength and good sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figure 1As shown, the corner block 300 of this embodiment is used to connect the first frame 100 and the second frame 200 of the door and window frame. Specifically, two corner blocks 300 can be provided at one connection end, and the two corner blocks 300 are respectively inserted into different cavities. Figure 4 and Figure 5 As shown, the corner block 300 is an L-shaped metal structure or plastic steel structure, preferably stainless steel or aluminum alloy, including a horizontal end 301 and a vertical end 302, and the horizontal end 301 and the vertical end 302 are respectively inserted into the first frame 100 and the second frame 200 to form a connection. The outer side surface of the horizontal end 301 is provided with a first threaded hole 303, and the outer side surface of the vertical end 302 is provided with a second threaded hole 304, and the two threaded holes are used for threaded connection with the two frames; the two side edges of the entire corner block 300 are raised to form a groove-shaped side glue groove 307, and the side glue groove 307 has a horizontal end glue outlet hole 305 at a position corresponding to the first threaded hole 303, and the side glue groove 307 has a vertical end glue outlet hole 306 at a position corresponding to the second threaded hole 304; as shown Figure 6 As shown, the corner block 300 has a glue storage chamber 311 for pre-stored colloid inside, and the first threaded hole 303 and the second threaded hole 304 are connected by a conducting cavity 310 whose inner diameter is larger than the threaded hole itself, the glue storage chamber 311 has a glue inlet 312 connected to the conducting cavity 310, and a sealing film 313 is sealed at the glue inlet 312; the horizontal end glue hole 305 is connected to the conducting cavity 310 at the bottom of the first threaded hole 303, and the vertical end glue hole 306 is connected to the conducting cavity 310 at the bottom of the second threaded hole 304, the two glue outlet holes and the two glue inlets 312 are respectively located on different sides of the same conducting cavity 310, and the glue outlet holes and glue inlets 312 in the same conducting cavity 310 together form the glue storage chamber 311 to apply glue to the side The glue outlet channel of the groove 307; the glue outlet channel is isolated and sealed in advance by the sealing film 313, and when the corner block 300 is installed in place, when the screws are screwed into the first threaded hole 303 and the second threaded hole 304, the sealing film 313 is pierced by the screws, and the glue in the glue storage chamber 311 flows out from the glue inlet 312, bypasses the outer periphery of the screw, and flows out from the horizontal end glue outlet hole 305 and the vertical end glue outlet hole 306 next to it, and fills the entire side glue application groove 307, forming an adhesive connection between the corner block 300 and the first frame 100 and the second frame 200; at the same time, the colloid fills the conduction cavity 310, fixes the screws in the threaded holes, and forms a seal to prevent water vapor and air from entering the door and window frame through the threaded holes, and then entering the room.

[0030] like Figure 7As shown, taking the first threaded hole 303 as an example, a conducting cavity 310 is set at the bottom of the first threaded hole 303, and the aperture of the conducting cavity 310 is larger than the aperture of the first threaded hole 303, so that after the screw is screwed in, the colloid can flow freely in the conducting cavity 310 from the periphery of the screw, and then flow from the glue inlet 312 on one side to the horizontal end glue outlet hole 305 on the other side, and then enter the side glue groove 307.
