Description

Technical Field

[0001] The utility model relates to the technical field of door and window hinges, in particular to a base structure and a sliding component for door and window hinges. Background Art

[0002] In the current door and window structure design, the base of the door and window hinge (or sliding support) is an important component that bears the opening and closing of the door and window sash. However, there are some significant problems in the design of the traditional door and window hinge base. Generally speaking, the base is only fixed to the door and window frame profile by screws. This fixing method has the following shortcomings:

[0003] First, the load-bearing capacity is low. Due to the single fixing method, which relies only on screws, the base is prone to produce large stress concentration when bearing the weight of the door and window sashes and the force during the opening and closing process, resulting in limited load-bearing capacity. In the process of long-term use, this design is prone to fatigue damage to the base, thereby reducing the overall stability.

[0004] Secondly, the screws are easy to loosen. Since the doors and windows will vibrate during the opening and closing process, these vibrations may cause the screws that fix the base to gradually loosen. Once the screws are loose, the stability of the base will be seriously affected, further exacerbating the reduction of the load-bearing capacity.

[0005] In addition, the base warping and door and window sash sagging are also common. When the screws are loose and the load-bearing capacity is insufficient, the base is prone to deformation, resulting in warping. At the same time, the door and window sashes are also prone to sagging due to lack of sufficient support, which not only affects the normal use of the window sashes, but also poses certain safety hazards.

[0006] On the other hand, the slider on the hinge is an important part of the hinge, and its performance cannot be ignored. The main function of the slider is to support the door and window sashes and ensure their stability during opening and closing. However, conventional sliders are usually only subjected to force on one side. After being subjected to force, the slider will tilt up, and there is a risk that the slider will fall off the slide groove on the base; there will also be problems with unsmooth sliding. These problems not only affect the normal use of the hinge, but may also increase the burden on the base, further affecting the overall performance of the door and window.

[0007] Therefore, it is necessary to further improve and perfect the prior art to overcome these deficiencies, and the present invention is made based on this situation. Utility Model Content

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] like Figures 1 to 4 As shown, the utility model describes an innovative base structure for door and window hinges, which is intended to improve the stability and load-bearing capacity of door and window hinges. The base structure is mainly composed of a door and window frame profile 1 and a base body 2. The door and window frame profile 1 is a standardized profile, and a standard profile notch 11 is provided on the upper part thereof, which is usually a standard European standard notch. Ribs 111 are provided on both sides of the standard profile notch 11.

[0031] The base body 2 is one of the components of the door and window hinge (the door and window hinge also includes a short arm and a long arm hinged or slidably connected to the base body 2, and the other ends of the long arm and the short arm are hinged to the support arm, and the door and window sash is installed on the support arm). The base body 2 is fixedly installed on the door and window frame profile 1, and it is located above the standard profile notch 11.

[0032] The special design of the base body 2 is that an innovative hook 21 is provided at its bottom. The hook 21 can be inserted into and hooked on the rib 111 on one side of the standard profile slot 11, that is, the hook 21 hooks the profile rib to bear the force, thereby achieving a firm connection between the base body 2 and the door and window frame profile 1. This design not only enhances the fixation of the base, but also reduces problems caused by loose screws, such as warping of the base edge and sagging of the door and window sashes.

[0033] Through this structural design, the base body 2 can be more firmly fixed on the door and window frame profile 1, improving the bearing capacity and stability of the entire hinge system. In addition, this hook-type fixing method also simplifies the installation process, reduces installation time and cost, and also improves the accuracy and reliability of installation.

[0034] More specifically, the hook 21 includes a boss 211 disposed at the bottom of the base body 2 and extending downward, and a hook portion 212 disposed on the left side (indoor side) or right side (outdoor side) of the boss 211 and facing outward (facing outward means facing away from the middle of the boss 211). The boss 211 can be inserted into the standard profile slot 11, and the hook 21 can be hung on the rib 111 on one side of the standard profile slot 11. This design enables the hook 21 to be more effectively inserted and hung on the door and window frame profile, thereby providing stronger fixing force and stability.

[0035] It is worth noting that the hook 21 of the base body 2 at the lower frame of the door and window is arranged on the left side (indoor side) of the boss 211, and the front side of the base body 2 faces upward. The base body 2 at the upper frame of the door and window is different, and the hook 21 is arranged on the right side (outdoor side) of the boss 211, and the front side of the base body 2 faces downward. This embodiment is described by taking the base body 2 installed at the lower frame of the door and window as an example.

[0036] In addition, the hook 21 extends along the length of the base body 2 to form a long strip structure. This long strip design increases the contact area between the hook 21 and the rib 111, thereby improving the strength and stability of the connection. The increase in contact area means that when the weight of the door and window sash and the opening and closing torque are borne, the hook 21 can disperse the pressure more evenly, reduce local stress concentration, and thus extend the service life of the hinge.

[0037] Although the hook 21 provides the main fixing method, the middle part of the base body 2 is still fixed to the door and window frame profile 1 by screws to further enhance the overall stability. The base body 2 is provided with a plurality of screw holes 25, which are used to install screws to ensure a firm connection between the base body 2 and the door and window frame profile 1. This screw fixing method not only provides additional security, but also facilitates installation and adjustment, making the entire hinge system more flexible and reliable.

[0038] As mentioned above, this innovative base structure significantly improves the load-bearing capacity and stability of door and window hinges by combining the dual fixing methods of hooks and screws, while simplifying the installation process and improving the accuracy and efficiency of installation.

[0039] The utility model not only relates to an innovative base structure for door and window hinges, but also further describes a sliding assembly for door and window hinges. Figures 1 to 4 As shown, the sliding assembly combines the above-mentioned base structure and introduces a slider 3 as a key sliding component. The slider 3 is installed on the base body 2 by a sliding connection. The upper part of the base body 2 is provided with a guide surface 22, and the bottom surface of the slider 3 is closely attached to the guide surface, ensuring the accuracy and stability of sliding.

[0040] In order to further enhance the stability and guiding property of the slider 3, the utility model sets a first limiting structure between the left side of the slider 3 and the left side of the base body 2, and sets a second limiting structure between the right side of the slider 3 and the right side of the base body 2. The first limiting structure is used to limit the left-right relative sliding between the slider 3 and the base body 2, while the second limiting structure is used to limit the up-and-down relative movement between the two. This double limiting design not only ensures the precise guiding of the slider 3 during the sliding process, but also enables the left and right sides of the slider 3 to be evenly stressed, thereby avoiding the slider warping problem common in traditional designs.

[0041] Through this balanced force design, the sliding block 3 slides more smoothly, reducing friction and wear, and improving the bearing capacity and service life of the hinge.

[0042] The sliding assembly of the utility model significantly improves the stability and sliding performance of the slider through the innovative limiting structure design, and at the same time enhances the overall load-bearing capacity and service life of the hinge.

[0043] More specifically, the first limiting structure includes a first convex rib 31 disposed vertically on the left side of the slider 3, and a first guide groove 23 disposed on the left side of the base body 2 and surrounding the first convex rib 31 from the left and right directions and slidingly cooperating with the first convex rib 31. This design achieves precise guidance and limiting of the slider 3 on the base body 2 through the cooperation of the convex rib and the groove.

[0044] Furthermore, the inner side of the base body 2 first extends upward, then extends rightward, and finally extends downward, thereby forming the first guide groove 23. This groove structure provides a stable guide path for the first ridge 31, ensuring the stability and accuracy of the slider 3 during the sliding process. At the same time, the left side of the slider 3 extends upward to form the first ridge 31, which is precisely inserted into the first guide groove 23, achieving a close fit between the slider 3 and the base body 2.

[0045] Through the coordinated design of the ridges and grooves, the first limiting structure not only effectively limits the left-right relative sliding between the slider 3 and the base body 2, but also enables the slider 3 to maintain stable guidance during the sliding process, avoiding the problem of offset or warping caused by unstable sliding.

[0046] More specifically, the second limiting structure includes a second ridge 24 disposed on the right side of the base body 2, and a second guide groove 32 disposed on the right side of the slider 3 and surrounding the second ridge 24 from both sides and slidingly cooperating with the second ridge 24. This design achieves precise guidance and limiting of the slider 3 on the base body 2 through the cooperation of the ridge and the groove.

[0047] Furthermore, the right side of the base body 2 first extends rightward and upward, and then continues to extend rightward, thereby forming the second convex ridge 24. This inclined design not only provides a stable guide path for the second convex ridge 24, but also facilitates production and assembly. At the same time, the right side of the slider 3 first extends downward, and then extends leftward, forming the second guide groove 32, which precisely surrounds the second convex ridge 24, thereby achieving a close fit between the slider 3 and the base body 2.

[0048] The second limiting structure not only effectively limits the up-and-down relative movement between the slider 3 and the base body 2, but also enables the slider 3 to maintain stable guidance during the sliding process, thereby avoiding the problem of offset or warping caused by unstable sliding.

[0049] More specifically, a friction adjustment structure for adjusting the friction between the slider 3 and the base body 2 is provided between the slider 3 and the base body 2. The design of this structure aims to optimize the performance of the sliding assembly by adjusting the friction between the slider 3 and the base body 2, so that the sliding effect can be maintained at the best under different usage scenarios and requirements.

[0050] Furthermore, the friction force adjustment structure includes a threaded hole 33 provided on the slider 3 and penetrating the slider 3, and a top screw 4 provided in the threaded hole 33. The design of the threaded hole 33 enables the top screw 4 to accurately adjust its upper and lower positions in the slider 3, thereby achieving accurate control of the friction force. The lower end of the top screw 4 can extend out of the threaded hole 33 and press onto the base body 2. This design enables the top screw 4 to directly act on the base body 2, and the friction force between the slider 3 and the base body 2 is adjusted by changing the pressure of the top screw 4.

[0051] In order to further optimize the effect of friction adjustment, a gasket 5 is further provided between the lower end of the top screw 4 and the base body 2. The function of the gasket 5 is to disperse the pressure of the top screw 4, prevent the top screw 4 from directly pressing on the base body 2 and causing damage, and also provide a smooth contact surface, reduce the unevenness during the friction adjustment process, and ensure that the friction adjustment is more stable and accurate.

[0052] Through the design of this friction adjustment structure, the user can adjust the position and pressure of the top screw 4 according to actual needs to achieve precise control of the friction between the slider 3 and the base body 2. This design improves the adaptability and flexibility of the sliding component and enhances the overall performance and service life of the hinge.
