Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a hydraulic hinge with a stable connection structure. Background Technology

[0002] Hinges are hardware accessories that connect doors, windows, cabinet doors, and other objects to enable rotation; they belong to the category of home decoration materials. Their main structure is mostly a two-fold metal blade, connected by a pivot pin to form a moving part. Common materials include stainless steel, brass, zinc alloy, and galvanized iron, with stainless steel being the most widely used, while zinc alloy is a commonly used material by mainstream domestic brands.

[0003] As people's living standards improve, the performance requirements for doors and windows in homes are also gradually increasing. To ensure the sound insulation, waterproofing, and heat insulation capabilities of doors and windows, more and more users are starting to use aluminum profile doors and windows, and generally use multi-layer tempered glass. This makes the overall weight of a single door or window sash heavier, especially for fire-resistant doors and windows in each household, which need to be filled with fire-resistant materials and steel components to ensure their fire resistance. The sash and frame are generally connected by hinges. The current hinge connection structure is relatively simple, using only two connecting blades to connect the sash and frame. After a period of use, the excessive weight of the inner sash may cause the connecting screws to deform, resulting in the inner sash becoming misaligned, affecting the user's use.

[0004] Therefore, how to achieve a stable connection between the outer frame and inner sash of aluminum alloy doors and windows is a technical problem that urgently needs to be solved in the industry. Utility Model Content

[0005] The main purpose of this utility model is to provide a hydraulic hinge with a stable connection structure, which aims to achieve a stable connection between the outer frame and inner sash of aluminum alloy doors and windows.

[0006] This utility model proposes a hydraulic hinge with a stable connection structure, including a shaft body, on which a first connecting blade and a second connecting blade are provided. An extension block adapted to the length of the first connecting blade is fixedly connected to the outer end of the first connecting blade. A snap-fit ​​strip is fixedly connected to the rear part of the outer side of the extension block. Multiple device slots are opened on the front end surface of the extension block. A snap-fit ​​tooth is laterally slidably connected inside the multiple device slots. Multiple springs are laterally fixedly connected between the inner end of the snap-fit ​​tooth and the inner end surface of the device slot.

[0007] Preferably, the outer surfaces of both the first connecting blade and the second connecting blade are provided with a plurality of connecting holes that extend laterally through them.

[0008] Preferably, the inner ends of the plurality of connecting holes are all expanded outward to form a recessed groove.

[0009] Preferably, the shaft body is provided with a hydraulic buffer structure inside.

[0010] Preferably, the lengths of the first connecting blade and the second connecting blade are both adapted to the length of the shaft.

[0011] Preferably, both ends of the shaft are provided with leak-proof caps.

[0012] This invention, by setting an extension block, a snap-fit ​​strip, and multiple snap teeth, allows the device to be installed by snapping the snap teeth and snap-fit ​​strip on the extension block at the outer end of the first connecting blade into the sealing strip groove in the middle of the inner surface of the aluminum alloy door and window frame profile. Then, screws are used to pass through multiple connecting holes to fix the first connecting blade onto the frame profile. In actual use, it can not only be supported by the screw structure, but also distribute part of the weight onto the frame profile through the extension block, thereby preventing the screws from deforming due to long-term stress and thus avoiding the problem of the inner sash of the door and window becoming crooked.

[0019] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0020] Reference Figure 1-4This invention proposes an embodiment of a hydraulic hinge with a stable connection structure, comprising a shaft 1, on which a first connecting blade 2 and a second connecting blade 3 are provided. An extension block 4 adapted to the length of the first connecting blade 2 is fixedly connected to the outer end of the first connecting blade 2. A snap-fit ​​strip 5 is fixedly connected to the rear part of the outer side of the extension block 4. A plurality of device grooves 6 are provided on the front end surface of the extension block 4. A snap-fit ​​tooth 7 is laterally slidably connected inside the plurality of device grooves 6. A plurality of springs 8 are laterally fixedly connected between the inner end of the snap-fit ​​tooth 7 and the inner end surface of the device groove 6.

[0021] Multiple connecting holes 10 are laterally opened on the outer surfaces of both the first connecting blade 2 and the second connecting blade 3.

[0022] During installation, the device can be inserted into the groove of the sealing strip in the middle of the inner surface of the aluminum alloy door and window frame by inserting the teeth 7 and the connecting strip 5 on the outer extension block of the first connecting blade 2 into the groove of the sealing strip in the middle of the inner surface of the aluminum alloy door and window frame. Then, the first connecting blade 2 is fixedly installed on the frame frame by passing screws through multiple connecting holes 10. In actual use, it can not only be supported by the screw structure, but also distribute part of the weight to the frame frame by the extension block 4, thereby avoiding the screws from deforming due to long-term stress, and thus avoiding the problem of the inner sash of the door and window being crooked.

[0023] The second connecting blade 3 is used to connect with the inner fan, and the two are fixed with screws. When installing the first connecting blade 2, the outer side of the extension block 4 is pressed against the outside of the sealing strip groove of the frame profile, and then pressed inward. Since the outer side of the locking tooth 7 is an inclined surface, the locking tooth 7 will be pushed into the inside of the device groove 6, and the outer part of the extension block 4 will enter the inside of the sealing groove. Then, the hinge is pulled outward, and the locking strip 5 will be locked with one end of the sealing groove. Multiple locking teeth 7 will also pop out under the action of spring 8 and lock with the other end of the sealing groove. Then, the first connecting blade 2 is fixed with screws. Through this structure, part of the weight of the inner fan can be distributed to the sealing groove structure of the outer frame. Since the outer frame is a whole structure in actual processing, its structural stability is strong and it is not easy to deform, thereby improving the support performance of the hinge and avoiding the problem of the inner fan tilting.

[0024] Furthermore, the inner ends of the multiple connecting holes 10 are all expanded outward to form a recessed groove.

[0025] Countersunk screws can hide the ends of screws, improving aesthetics without affecting the normal opening and closing of the hinge.

[0026] Furthermore, a hydraulic buffer structure 9 is provided inside the shaft 1.

[0027] Both ends of shaft 1 are equipped with leak-proof caps.

[0028] The hydraulic buffer structure 9 enables the doors and windows to close slowly, reducing noise and preventing violent collisions between the frame and sash, thus improving service life. It is a mature existing technology, and the specific structure will not be described in detail here. The anti-leakage caps at both ends of the shaft 1 can prevent hydraulic oil from overflowing.

[0029] Furthermore, the lengths of the first connecting blade 2 and the second connecting blade 3 are both adapted to the length of the shaft 1.

[0030] The lengths of the first connecting blade 2 and the second connecting blade 3 are adapted to the length of the shaft 1, making the connection surface between the two and the outer frame and the inner fan larger, which allows for the installation of more screws and further improves the connection stability of the hinge.

[0031] During installation, the device can be inserted into the groove of the sealing strip in the middle of the inner surface of the aluminum alloy door and window frame by inserting the teeth 7 and the connecting strip 5 on the outer extension block of the first connecting blade 2 into the groove of the sealing strip in the middle of the inner surface of the aluminum alloy door and window frame. Then, the first connecting blade 2 is fixedly installed on the frame frame by passing screws through multiple connecting holes 10. In actual use, it can not only be supported by the screw structure, but also distribute part of the weight to the frame frame by the extension block 4, thereby avoiding the screws from deforming due to long-term stress, and thus avoiding the problem of the inner sash of the door and window being crooked.

[0032] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
