[0002] In related technologies, the installation of glass doors and windows in buildings often employs an external mounting method. This involves connecting the glass door / window frame profiles and connecting brackets, and then fixing the connecting brackets to the base wall. Specifically, mounting holes need to be drilled in the frame profiles and connecting brackets, and screws are screwed into the mounting holes to connect the frame and the connecting brackets. However, the screwing process often damages the mechanical strength of the profiles. Taking the widely used fiberglass reinforced polyurethane profile windows as an example, this profile is relatively brittle and is prone to brittle cracking due to the pressure of the screws when they are screwed in, which significantly affects its durability.

[0008] A first limiting member is disposed on the rod body and is used to abut against the side of the bracket away from the profile.

[0009] According to the connecting assembly of this utility model, each of the blades has a shaft hole at one end that is adapted to the shaft body, and a snap-fit ​​part at the other end; the two blades are rotatably sleeved on the shaft body through the shaft hole in sequence, and the snap-fit ​​part is used to snap-fit ​​with the slot on the profile.

[0010] According to the connecting assembly of this utility model, a second limiting member is detachably installed at the end of the shaft, and the second limiting member abuts against the outer side of the wing away from the rod.

[0011] According to the connecting assembly of this utility model, the torsion member is a torsion spring, the torsion spring includes a spring coil and two torsion arms respectively formed on both sides of the spring coil, the spring coil is sleeved on the shaft, and the torsion arms and the blades are connected one-to-one.

[0012] According to the connecting assembly of this utility model, the width of the wing is not greater than the diameter of the rod.

[0013] According to the connecting assembly of this utility model, the first limiting member includes a nut, a washer, and a spring washer;

[0014] The rod body has a thread adapted to the nut, and the washer, the spring washer and the nut are sequentially sleeved on the rod body in a direction away from the bracket; the nut is used to press the washer onto the bracket through the spring washer.

[0015] According to the connecting component of this utility model, the diameter of the rod is not less than 3mm and not more than 5mm; the length of the rod is not less than 30mm.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] The following is combined with Figure 1 This invention describes the connecting component of the present invention.

[0031] like Figure 1 As shown, this utility model provides a connecting assembly 1 for fixing a bracket 2 and a profile 3. The bracket 2 has a first connecting hole, and the profile 3 has a second connecting hole corresponding to the first connecting hole. The connecting assembly 1 includes: a rod 11, two flaps 12, a torque member (not shown in the figure), and a first limiting member 13. A protruding shaft is provided on the side of the rod 11, and the rod 11 is used to pass through the first connecting hole and the second connecting hole. Both flaps 12 are rotatably mounted on the shaft. The torque member is disposed between the two flaps 12 to drive the two flaps 12 to unfold to both sides relative to the rod 11, so as to engage in the slot 31 on the side of the profile 3 opposite to the bracket 2. The first limiting member 13 is disposed on the rod 11 and is used to abut against the side of the bracket 2 opposite to the profile 3.

[0032] It is understood that profile 3 is typically the frame of a door or window. Bracket 2 is used to fix profile 3 and connect it to the wall so that the door or window can be installed on the building wall. When connecting profile 3 and bracket 2, holes need to be drilled on the mounting surfaces where they contact each other, so that corresponding first connecting holes and second connecting holes are formed on bracket 2 and profile 3 respectively. When installing profile 3 and bracket 2, the first connecting holes and second connecting holes align with each other, allowing the connecting component 1 of this embodiment to securely connect profile 3 and bracket 2 by engaging the first connecting holes and second connecting holes.

[0033] Specifically, the side of the rod 11 of the connecting assembly 1 is provided with a protruding shaft. The protruding shaft is used to rotatably mount two blades 12. The two blades 12 can rotate around the shaft, so that the two blades 12 are in an unfolded state or a closed state. When the two blades 12 are in the closed state, the two blades 12 are close to each other and the length direction of the two blades 12 is parallel to the length direction of the rod 11. This allows the cross-sectional area of ​​the overall structure of the blades 12 and the rod 11 to be minimized, so that the rod 11 and the blades 12 can pass through the first connecting hole and the second connecting hole in sequence. Meanwhile, by setting a torsion member between the two blades 12 to drive the two blades 12 to unfold to both sides respectively, when the two blades 12 pass through the first connecting hole and the second connecting hole, the two blades 12 are in a closed state, and the torsion member is compressed by the two blades 12. After the two blades 12 have completely passed through the second connecting hole, the torsion member is released, driving the two blades 12 to unfold to both sides respectively, and engage with the slot 31 of the profile 3 to fix the connecting assembly 1 to the profile 3. In addition, a first limiting member 13 is also provided on the rod 11. The first limiting member 13 abuts against the side of the bracket 2 away from the profile 3, so as to press the bracket 2 tightly onto the profile 3, thereby fixing the bracket 2 and the profile 3 to each other.

[0034] The connecting component 1 of this utility model has a first limiting member 13 on the rod 11 and two rotatable flaps 12 on the shaft on the side of the rod 11. A torque member for driving the flaps 12 to unfold is provided between the two flaps 12. When connecting the bracket 2 and the profile 3, the two flaps 12 can be closed on the rod 11 first, and the two flaps 12 and the rod 11 can be passed through the first connecting hole and the second connecting hole in sequence. After the two flaps 12 have completely passed through the second connecting hole, they will automatically unfold to both sides under the drive of the torque member and lock into the slot 31 of the profile 3, thereby connecting the two flaps 12. Component 1 is fixed to profile 3. At the same time, the second limiting member 111 located on the other side of profile 3 and bracket 2 presses bracket 2 onto profile 3 to fix profile 3 and bracket 2. There is no need to construct threads on rod 11. During installation, rod 11 will not squeeze or rub against the wall of the second connecting hole on profile 3, thereby avoiding brittle cracking of profile 3 due to compression. This effectively solves the defect in the prior art where, when connecting the frame profile and connecting bracket of glass door and window with screws, the threaded surface of the screw squeezes and rubs against the profile during the screwing process, which easily causes the profile to crack and affects the service life of the profile.

[0035] Specifically, in some embodiments, such as Figure 1 As shown, each blade 12 has a shaft hole at one end that fits the shaft body, and a snap-fit ​​part at the other end. The two blades 12 are rotatably fitted onto the shaft body through the shaft hole, and the snap-fit ​​part is used to snap into the slot 31 on the profile 3.

[0036] In this embodiment, by opening a shaft hole at the end of each wing 12, the two wing 12 can be stacked and sleeved on the shaft, and rotate around the shaft. The structure is simple and makes the wing 12 and the rod 11 more compact. The other end of the two wing 12 is constructed with a snap-fit ​​part that matches the slot 31 on the profile 3, so that when the two wing 12 are unfolded, they snap into the corresponding slot 31 to support and fix the entire connecting assembly 1.

[0037] Specifically, such as Figure 1 As shown, a second limiting member 111 is detachably installed at the end of the shaft, and the second limiting member 111 abuts against the outer side of the wing 12 away from the rod 11.

[0038] In this embodiment, a second limiting member 111 is installed at the end of the shaft. The second limiting member 111 is located outside the two blades 12, and part of its structure extends radially to the outside of the shaft to limit the two blades 12 and prevent the blades 12 from falling off the shaft.

[0039] Specifically, a screw hole can be opened at the end of the shaft, and the second limiting member 111 can be a bolt that is adapted to the screw hole. The nut part of the bolt is used to limit the blade 12.

[0040] Specifically, in some embodiments, such as Figure 1 As shown, the torsion element is a torsion spring, which includes a spring coil and two torsion arms formed on both sides of the spring coil. The spring coil is sleeved on the shaft, and the torsion arms and the blades 12 are connected one-to-one.

[0041] In this embodiment, the spring coil of the torsion spring can be sleeved on the shaft without the need for an additional fixing structure. The two torsion arms of the torsion spring are connected to the two blades 12 respectively. When the two blades 12 are closed, the two torsion arms are squeezed and twisted. After the two blades 12 are released, the torsion spring can drive the two blades 12 to unfold to both sides.

[0042] Alternatively, in some embodiments, such as Figure 1 As shown, the width of the wing 12 is not greater than the diameter of the rod 11.

[0043] It is understood that when the two blades 12 are in the closed state, either blade 12 and the rod 11 are arranged in a radially overlapping manner. The blade 12 typically has dimensions in three directions: width, thickness, and length. In the closed state, the thickness direction of the blade 12 extends radially along the rod 11, the length direction extends axially along the rod 11, and the width direction remains perpendicular to both the length and thickness directions. In this embodiment, by designing the width of the blade 12 to be no greater than the diameter of the rod 11, the cross-sectional area of ​​the blade 12 and the rod 11 can be smaller when the two blades 12 are in the retracted state. This reduces the size of the first connecting hole on the bracket 2 and the second connecting hole on the profile 3, thus minimizing the structural damage caused by drilling to the bracket 2 and the profile 3.

[0044] Optionally, the first limiting member 13 can be fixed to the rod 11, or it can move along the axial direction of the rod 11 to adjust its position.

[0045] Specifically, in some embodiments, such as Figure 1 As shown, the first limiting member 13 includes a nut 131, a washer 132, and a spring washer 133. A thread adapted to the nut 131 is formed on the rod body 11. The washer 132, spring washer 133, and nut 131 are sequentially fitted onto the rod body 11 in a direction away from the bracket 2. The nut 131 is used to press the washer 132 onto the bracket 2 via the spring washer 133.

[0046] In this embodiment, a thread is provided on the rod 11 to install the nut 131, and the position of the nut 131 can be adjusted along the axial direction of the rod 11. A washer 132 is provided between the nut 131 and the bracket 2. The nut 131 presses the bracket 2 onto the profile 3 through the washer 132. The washer 132 can increase the force-bearing area of ​​the bracket 2, making the force more uniform, the bracket 2 more robust, and less prone to damage due to excessive local pressure. Meanwhile, a spring washer 133 is provided between the washer 132 and the nut 131. The spring washer 133 is used to transmit pressure between the washer 132 and the nut 131. When the washer 132 or the nut 131 shifts along the axial direction of the rod 11, the spring washer 133 can still maintain contact with the washer 132 and the nut 131, pressing the washer 132 tightly onto the bracket 2, so as to prevent the washer 132 or the nut 131 from shifting along the axial direction of the rod 11 and causing them to lose contact, thereby causing the bracket 2 and the profile 3 to loosen.

[0047] Specifically, in some embodiments, the diameter of the rod 11 is not less than 3mm and not more than 5mm. The length of the rod 11 is not less than 30mm. In this embodiment, by setting the diameter and length of the rod 11, while ensuring that the entire connecting assembly 1 can form an effective mechanical connection between the profile 3 and the bracket 2, it is also possible to avoid forming excessively large linear thermal bridges in the profile 3, which would affect the energy-saving performance of the door and window structure.

[0048] On the other hand, this application also provides a door and window mounting component, such as Figure 1 As shown, it includes: profile 3, bracket 2, and connection component 1 provided in any of the above embodiments. The door and window installation assembly of this application, by adopting the above-described connection component 1, also has the advantages of the above-described connection component 1, which will not be described in detail here.

[0049] The bracket 2 has a first connecting hole, and the profile 3 has a second connecting hole corresponding to the first connecting hole. The first connecting hole and the second connecting hole are connected. The profile 3 has a slot 31 that corresponds to the wing 12. The rod 11 passes through the first connecting hole and the second connecting hole in sequence. The first limiting member 13 abuts against the side of the bracket 2 away from the profile 3, and the wing 12 is engaged in the corresponding slot 31.

[0050] In this embodiment, the bracket 2 is used to connect to the building wall, and the profile 3 can serve as the frame structure for doors and windows, where doors or windows are installed. The connecting assembly 1 is used to fix the profile 3 and the bracket 2 together so that the entire door or window can be installed on the building wall.

[0051] Specifically, such as Figure 1 As shown, the bracket 2 has an L-shaped structure, including a first part and a second part that are perpendicular to each other and connected. The first part is used to connect with the building wall, and the second part is provided with a first connecting hole for fitting with the surface of the profile 3.

[0052] Specifically, in some embodiments, such as Figure 1 As shown, the two slots 31 are arranged symmetrically about the central axis of the rod 11.

[0053] In this embodiment, by setting the two slots 31 to be arranged symmetrically about the central axis of the rod 11, the distance between the rod 11 and the two slots 31 is equal after the rod 11 passes through the first connecting hole and the second connecting hole. The two flaps 12 on the rod 11 unfold to both sides under the drive of the torque member, so that they can contact the corresponding slots 31 as simultaneously as possible. This ensures that the contact force between the two flaps 12 and the corresponding slots 31 is basically consistent, so as to better support and fix the rod 11 and prevent the rod 11 from tilting to one side.

[0054] Specifically, in some embodiments, such as Figure 1 As shown, the profile 3 has a cavity 32 inside, the second connecting hole is connected to the cavity 32, and the slot 31 is set inside the cavity 32.

[0055] In this embodiment, by constructing a cavity 32 that communicates with the second connecting hole in the profile 3, the rod 11 and the wing 12 enter the cavity 32 after passing through the second connecting hole. The two wings 12 are opened to both sides under the drive of the torque member and engage with the corresponding slots 31 inside the cavity 32.

[0056] Specifically, such as Figure 1 As shown, the cavity 32 can be provided with two oppositely arranged card holders, and the second connecting hole is provided between the two card holders. Each of the two card holders has a card slot 31 formed on it.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
