Description

Technical Field

[0001] This utility model relates to the field of hinges, and more particularly to heavy-duty aluminum alloy hinges adapted to reinforced connection methods. Background Technology

[0002] With the development of the entrance door industry, the main material used to produce entrance doors has gradually shifted from steel to aluminum alloy. Aluminum alloy is favored by the market for its excellent corrosion resistance, easy processing, low deformation rate, low density, light weight, high hardness, and easy surface color processing. Traditionally, front door hinges were installed on one side of the door frame and the other side of the door leaf, directly fixed to the mounting holes in the hinge and the door frame / leaf with screws. Steel front doors, being made of steel, could have their hinge back plates (thick iron plates typically around 5mm thick) welded on to extend the depth of the hinge fixing screws, thus achieving structural reinforcement. Currently, aluminum alloy front doors generally increase the wall thickness at the hinge fixing point during profile extrusion to extend the connection depth between the hinge screws and the profile. The common practice is to manually or mechanically process the hinge fixing points in the 2.5-5mm thick aluminum alloy door frame / leaf, first milling holes and then tapping them to create the necessary screw holes. While this method can solve the hinge fixing problem to some extent and meet the requirements of load-bearing environments, it still has shortcomings:

[0003] Aluminum alloys inherently have low density, making them susceptible to stripping during milling and tapping if the angle and torque are not properly controlled. Even with proper machining, repeated loosening and tightening of the hinge mounting screws during final installation can cause stripping due to variations in torque and angle, rendering the hinges ineffective. Some hinges may not appear loose on the surface, but with increased use and frequency of entryway door applications, there is a risk of the hinges detaching at the hinge joint. Therefore, even increasing the wall thickness of the aluminum alloy profile at the hinge joint cannot completely eliminate the risks and potential hazards associated with incompletely securing the hinge screws.

[0004] Therefore, it is necessary to provide a new type of heavy-duty aluminum alloy hinge that adapts to and reinforces the connection method to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an aluminum alloy heavy-duty hinge that is adapted to a reinforced connection method.

[0006] The heavy-duty aluminum alloy hinge with a reinforced connection method provided by this utility model includes a door frame, a door leaf, a hinge seat one, a hinge seat two, and two opposing aluminum alloy mounting seats. The hinge seat one and the hinge seat two are rotatably mounted on the two aluminum alloy mounting seats respectively. The two aluminum alloy mounting seats are fixedly connected to the door frame and the door leaf respectively. The inner side of the door frame and the door leaf are provided with a reinforcing groove for fixing the two aluminum alloy mounting seats. The middle part of the hinge seat one is provided with a connecting groove, and a connecting rod is fixedly connected in the connecting groove. The middle part of the hinge seat two is rotatably mounted on the connecting rod. The other end of the hinge seat one is slidably mounted on one of the aluminum alloy mounting seats, and the other end of the hinge seat two is slidably mounted on the other aluminum alloy mounting seat.

[0007] Furthermore, one end of both the first hinge seat and the second hinge seat are bent inward.

[0008] Furthermore, the aluminum alloy mounting base includes a connecting base and a fixing base. The connecting base has a sliding groove for sliding the first hinge base or the second hinge base. The connecting base is rotatably connected to the first hinge base or the second hinge base.

[0009] Furthermore, the top of the connecting seat is provided with an adjustment groove, the fixing seat is slidably installed in the adjustment groove, and the fixing seat and the adjustment groove are fixedly connected by screws.

[0010] Furthermore, the mounting base has multiple mounting holes, each containing a pull nut, and the pull nut has an internal thread connected to a fastening screw.

[0011] Furthermore, both the first hinge seat and the second hinge seat are provided with sound-silencing pads.

[0012] Compared with related technologies, the aluminum alloy heavy-duty hinge with adapted and reinforced connection method provided by this utility model has the following beneficial effects:

[0013] This utility model provides a heavy-duty aluminum alloy hinge adapted for reinforced connection methods. In specific implementation, the interlocking design of the reinforcing grooves within the door frame and door leaf with the aluminum alloy mounting base, along with the processing of the hinge's external structure, enhances the correspondence between the hinge's reinforcing grooves and the aluminum alloy profile structure, thereby reinforcing the hinge. Even if screws loosen and fall off, the risk of the hinge detaching from the door frame is greatly reduced, significantly improving structural stability. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 as well as Figure 9 ,in, Figure 1 Schematic diagram of the overall structure of the aluminum alloy heavy-duty hinge with adapted and reinforced connection method provided by this utility model Figure 1 ; Figure 2 Schematic diagram of the overall structure of the aluminum alloy heavy-duty hinge with adapted and reinforced connection method provided by this utility model Figure 2 ; Figure 3This is a schematic diagram of the structure of the hinge seat provided by this utility model; Figure 4 for Figure 3 The enlarged structural diagram at point A is shown below; Figure 5 This is a schematic diagram of the structure of the hinge seat 2 provided by this utility model; Figure 6 A cross-sectional view of the door frame and aluminum alloy mounting base provided by this utility model; Figure 7 for Figure 6 The enlarged structural diagram at point B is shown below; Figure 8 for Figure 6 The enlarged structural diagram at point C is shown below; Figure 9 A schematic diagram of the structure of the connector provided by this utility model.

[0026] In the specific implementation process, such as Figures 1-9 As shown, the heavy-duty aluminum alloy hinge with a reinforced connection method includes a door frame, a door leaf, a hinge base 1, a hinge base 2, and two opposing aluminum alloy mounting bases 3. The hinge base 1 and the hinge base 2 are rotatably mounted on the two aluminum alloy mounting bases 3, and the two aluminum alloy mounting bases 3 are fixedly connected to the door frame and the door leaf, respectively. The inner side of the door frame and the door leaf are provided with a reinforcing groove 4 for fixing the two aluminum alloy mounting bases 3. One end of the hinge base 1 and the hinge base 2 are bent inward. The middle part of the hinge base 1 is provided with a connecting groove 5, and a connecting rod 6 is fixedly connected in the connecting groove 5. The middle part of the hinge base 2 is rotatably mounted on the connecting rod 6. The other end of the hinge base 1 is slidably mounted on one of the aluminum alloy mounting bases 3, and the other end of the hinge base 2 is slidably mounted on the other aluminum alloy mounting base 3.

[0027] One end of hinge seat 1 is bent inward and slidably connected to the aluminum alloy mounting seat 3 on the door frame side. A connecting groove 5 is opened in the middle, and a connecting rod 6 is embedded in the connecting groove 5 to provide a rotation fulcrum for hinge seat 2. One end of hinge seat 2 is bent inward and slidably connected to the aluminum alloy mounting seat 3 on the door leaf side. The middle part of hinge seat 2 is rotatably mounted on the connecting rod 6 to achieve dynamic cooperation with hinge seat 1. When the door leaf is opened and closed, hinge seat 1 slides in the sliding groove 9 of the aluminum alloy mounting seat 3 on the door frame side, and hinge seat 2 slides in the sliding groove 9 of the aluminum alloy mounting seat 3 on the door leaf side. The connecting rod 6 serves as a rotation fulcrum, so that hinge seat 1 and hinge seat 2 form a four-bar linkage mechanism to adapt to the arc-shaped movement trajectory of the door leaf.

[0028] It should be noted that the reference Figure 3 as well as Figure 4 As shown, both hinge seat 1 and hinge seat 2 are provided with sound-absorbing pads 14 (such as rubber or silicone material) at the connection points. The sound-absorbing pads 14 absorb the vibration energy generated by metal friction.

[0029] In a specific implementation process, refer to Figure 5 , Figure 6 as well as Figure 8 As shown, the aluminum alloy mounting base 3 includes a connecting base 7 and a fixing base 8. The connecting base 7 has a sliding groove 9 for sliding the hinge base 1 or the hinge base 2. The connecting base 7 is rotatably connected to the hinge base 1 or the hinge base 2. The top of the connecting base 7 has an adjustment groove 10. The fixing base 8 is slidably installed in the adjustment groove 10, and the fixing base 8 and the adjustment groove 10 are fixedly connected by screws. The position of the fixing base 8 is adjusted by screws to compensate for the slight deformation caused by long-term use. The fixing base 8 has multiple mounting holes 11, and each mounting hole 11 is provided with a pull nut 12. The pull nut 12 is threaded with a fastening screw 13. By processing the screw hole positions of the hinge, the hole space is changed, and the reserved position of the 304 stainless steel pull nut 12 accessory is increased. This type of accessory can increase the mutual connection strength of the screw threads. The pull nut 12 lengthens the connection depth of the hinge mounting screw, effectively reducing unnecessary aluminum profile wall thickness and achieving the purpose of energy saving and emission reduction.

[0030] The working principle provided by this utility model is as follows: When the door leaf is opened and closed, the hinge seat 1 slides in the sliding groove 9 of the aluminum alloy mounting seat 3 on the door frame side, and the hinge seat 2 slides in the sliding groove 9 of the aluminum alloy mounting seat 3 on the door leaf side. The connecting rod 6 serves as a rotation fulcrum, so that the hinge seat 1 and the hinge seat 2 form a four-bar linkage mechanism, which adapts to the arc-shaped movement trajectory of the door leaf. The sound-absorbing pad 14 absorbs the vibration energy generated by metal friction. The position of the fixing seat 8 is adjusted by screws to compensate for the small deformation caused by long-term use.
