Description

Technical Field

[0001] This utility model belongs to the field of door and window hinge technology, specifically relating to a long, non-drilling, damping buffer hinge. Background Technology

[0002] Currently, there are many types of hinges on the market. However, in some scenarios requiring a buffering function, traditional hinges suffer from problems such as excessively fast return speed and high impact force when closing, which can easily lead to damage to the door and frame, as well as generating significant noise and a poor user experience. Some hinges with buffering functions have complex structures, requiring notches to be made in the door or frame during installation, increasing installation difficulty and damage to components. Furthermore, existing hinges have the following problems in use: ordinary hinges, lacking a buffering structure, allow the door to return to its original position quickly when closing, generating significant impact force, which not only causes noise but may also damage the door and window structure or create safety hazards; some damping hinges require installation grooves to be made in the door and window frames, increasing installation complexity and potential damage to doors and windows, and the damping effect is unstable. Utility Model Content

[0003] The purpose of this invention is to provide a long, non-disconnectable damping and buffer hinge to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a long, non-displacement damping buffer hinge, comprising a long, non-displacement hydraulic concave casting fixed to a glass door and a long, non-displacement hydraulic square casting fixed to a glass door frame. The upper surfaces of both the long, non-displacement hydraulic concave casting and the long, non-displacement hydraulic square casting are fixed with two layers of long, non-displacement hydraulic anti-slip pads by anti-slip screws. These pads are used to provide anti-slip fixation and protection for both sides of the movable glass door and the glass door frame. It also includes a sealing plate for sealing the inner sides of the ends of the long, non-displacement hydraulic concave casting and the long, non-displacement hydraulic square casting, and a cover panel that snaps onto the upper surface of the long, non-displacement hydraulic anti-slip pads. The cover panel surface is covered and locked with a long, non-displacement hydraulic cover.

[0005] A long, non-cutting hydraulic block is rotatably mounted at the opening of one end of the elongated, non-cutting hydraulic concave casting, which is used to achieve damped buffering opening and closing positioning of the glass door. The other end of the elongated, non-cutting hydraulic block is fixed to one end of the elongated, non-cutting hydraulic square casting by a cylindrical head hexagonal screw, and a hinge spindle is inserted into the through shaft hole at one end of the elongated, non-cutting hydraulic block. The hinge spindle is positioned and connected to the inside of the opening of the elongated, non-cutting hydraulic concave casting to achieve buffered hydraulic opening and closing positioning of the glass door.

[0006] Preferably, the elongated, non-drilling hydraulic block has a through hole for the main shaft on one side, allowing the hinge main shaft to pass through and rotate; the other end has symmetrically arranged assembly slots, in which a hydraulic cylinder and a steel ingot are respectively installed. During the opening and closing of the glass door, one end of the hydraulic cylinder presses against one end of the hinge main shaft, so that the hinge main shaft can achieve damped hydraulic slow rotation under the cooperation of the hydraulic cylinder and the steel ingot.

[0007] Preferably, a spring is fitted onto the protruding cylinder at the center of one end of the steel ingot, and the spring is disposed in the assembly groove. One end of both the spring and the hydraulic cylinder rests against the corresponding surface connecting the elongated, non-notched hydraulic square casting and the elongated, non-notched hydraulic block. One end of the assembly groove containing the steel ingot and the hydraulic cylinder communicates with the through hole of the main shaft and fits against both ends of the hinge main shaft. A concave positioning point is provided at the center of one side of the steel ingot; after the glass door is closed, this concave positioning point is used to position the hinge main shaft.

[0008] Preferably, bearings are sleeved at both ends of the hinge spindle, and the bearings are fixed inside the through holes at both ends of the spindle. A convex positioning point is provided at the center of the semi-circular surface of the hinge spindle body, and the upper and lower sides of the semi-circular plane of the spindle body are inclined surfaces, which facilitates the interaction between the steel ingot and the spring and the inclined surfaces on the semi-circular surface of the hinge spindle body, so that the glass door can instantly return to a certain angle. As the hinge spindle rotates, the convex positioning point rotates accordingly. When the glass door is closed, the convex positioning point on the semi-circular surface of the hinge spindle body is embedded in the concave positioning point to achieve positioning. The other end of the hinge spindle body surface is elliptical and flat. During the rotation of the hinge spindle, it can cause the hydraulic cylinder to perform a hydraulic rebound motion, so that after the glass door is instantly closed to a certain angle, it returns to its original position through the damping hydraulic action of the hydraulic cylinder, and finally becomes flush with the glass door frame.

[0009] Preferably, the hinge spindle has a protective rubber strip on the inner side of the opening at one end of the elongated hydraulic concave casting, corresponding to the semi-circular surface of the spindle body. During the opening and closing of the glass door, the protective rubber strip reduces the friction between the elongated hydraulic concave casting and the elongated hydraulic block. One side of the strip is attached to the semi-circular surface of the hinge spindle body. The spring force and the damping force of the hydraulic cylinder work together to achieve the slow return of the hinge.

[0010] Preferably, both the elongated, non-notch hydraulic concave casting and the elongated, non-notch hydraulic square casting have symmetrically arranged fixed columns with internal threads at the center of their end faces. Plastic sleeves B and A are sequentially fitted onto the fixed columns. The combination of these two sleeves on the fixed columns protects the glass door from wear and sagging during use. Anti-slip screws are used to fix the cover panel, two layers of elongated, non-notch hydraulic anti-slip pads, sealing plate, plastic sleeves B and A to the upper end faces of the elongated, non-notch hydraulic concave casting and the elongated, non-notch hydraulic square casting, thereby achieving clamping and fixing of both sides of the glass door and the glass door frame.

[0011] Preferably, after the elongated hydraulic cover is placed on the cover panel, a set bolt with a threaded hole through one side of the outer side of the elongated hydraulic cover is used to tighten one side of the cover panel, thereby fixing the elongated hydraulic cover to the cover panel.

[0012] Preferably, the bearings at both ends of the hinge spindle are fixed inside the spindle through holes to ensure stable rotation of the hinge spindle within the spindle through holes. Positioning grooves are provided on both inner side walls of the opening at one end of the elongated, non-cutting hydraulically cast hinge spindle for positioning and fixing both ends of the hinge spindle.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] Highly efficient cushioning and shock absorption enhances user experience and safety: Through the coordinated operation of hydraulic cylinders, steel ingots, springs, and a specially designed hinge spindle, the glass door opens and closes with damped hydraulic rotation, allowing for a slow and gentle rotation. Simultaneously, upon closing, the glass door instantly returns to a certain angle before smoothly returning to its flush position with the door frame via hydraulic cylinder damping. This effectively solves the problems of excessively fast closing speed and high impact force associated with traditional hinges, preventing damage from collisions between the door and frame, significantly reducing closing noise, eliminating safety hazards, and substantially improving user experience and safety.

[0015] No-cut installation, reducing installation difficulty and component damage: The design of long, no-cut hydraulic concave casting and long, no-cut hydraulic square casting allows for installation without the need to create notches in the glass door or frame. Compared to some damping hinges that require installation grooves in the door or window frame, this not only reduces installation complexity but also avoids damage to door and window components, protecting the structural integrity of the doors and windows and saving installation time and labor costs.

[0016] The robust structure ensures stable and reliable damping: All hinge components are tightly fitted and precisely positioned. For example, the bearings at both ends of the hinge spindle ensure stable rotation within the spindle's through-hole, while the elongated, non-cutting, hydraulically cast positioning grooves fix the ends of the spindle in place. Simultaneously, the steel ingot and the convex and concave positioning points on the hinge spindle work together to achieve precise positioning after the glass door is closed. These design features ensure the overall structural stability of the hinge, thereby stabilizing the damping effect, preventing instability, and extending the hinge's lifespan.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7This utility model provides a technical solution: a long, non-notch damping buffer hinge, comprising a long, non-notch hydraulic concave casting 19 fixed to the glass door and a long, non-notch hydraulic square casting 12 fixed to the glass door frame. From a practical application perspective, this design, where the hinge is fixed to the door and frame respectively, is suitable for glass door installations in shopping malls, office buildings, hotels, and other similar locations. It effectively supports the weight of the glass door, ensuring stable opening and closing. Both the long, non-notch hydraulic concave casting 19 and the long, non-notch hydraulic square casting 12 have two layers of long, non-notch hydraulic anti-slip pads 7 fixed to their upper surfaces by anti-slip screws 1. These pads provide anti-slip fixation and protection for both the movable glass door and the glass door frame. The anti-slip pads feature a special anti-slip texture design, increasing friction with the glass surface and preventing displacement between the glass door and the hinge even in humid environments or under external impact. It also includes a sealing plate 8 for sealing the inner side of the ends of the long, non-cutting hydraulic concave casting 19 and the long, non-cutting hydraulic square casting 12. The sealing plate 8 not only serves to prevent dust and water, but also protects the internal structure and extends the service life of the hinge. The cover panel 4 is fastened to the upper surface of the long, non-cutting hydraulic anti-slip pad 7, and the surface of the cover panel 4 is covered and locked with the long, non-cutting hydraulic cover 2. The long, non-cutting hydraulic cover 2 is made of high-strength metal material and is manufactured by precision casting process. It has good wear resistance and corrosion resistance and can effectively protect the internal structure from external damage.

[0027] A long, non-cut hydraulic concave casting 19 has a rotatable long, non-cut hydraulic block 11 at one end of its opening. This block is used to achieve damped, buffered opening and closing of the glass door. In public places where glass doors are frequently opened and closed, this design effectively slows down the closing speed, preventing noise and damage caused by collisions. The other end of the long, non-cut hydraulic block 11 is fixed to one end of the long, non-cut hydraulic square casting 12 by a cylindrical head hexagonal screw. The cylindrical head hexagonal screw has high fastening strength and anti-loosening performance, ensuring the stability of the connection. A hinge spindle 18 is inserted into the through-hole at one end of the long, non-cut hydraulic block 11. This hinge spindle 18 is positioned and connected to the inside of the opening of the long, non-cut hydraulic concave casting 19 to achieve buffered, pressure-driven opening and closing of the glass door. The hinge spindle 18, as the core rotating component, is made of high-strength alloy steel and undergoes a special heat treatment process, giving it good toughness and fatigue resistance, and enabling it to withstand frequent rotation over a long period of time.

[0028] The elongated, non-cut hydraulic block 11 has a through-hole 20 on one side for the hinge spindle 18 to pass through and rotate; the other end has symmetrically arranged mounting slots 21, in which a hydraulic cylinder 10 and a steel ingot 15 are respectively installed. In actual operation, the coordinated work of the hydraulic cylinder 10 and the steel ingot 15 is key to achieving damping and buffering. During the opening and closing of the glass door, one end of the hydraulic cylinder 10 presses against one end surface of the hinge spindle 18, causing the hinge spindle 18 to rotate slowly with damping hydraulic pressure under the cooperation of the hydraulic cylinder 10 and the steel ingot 15. The hydraulic cylinder 10 uses a high-precision sealing structure to ensure that the hydraulic oil does not leak, and at the same time, a stable damping effect is achieved by precisely controlling the flow rate of the hydraulic oil.

[0029] A spring 14 is fitted onto a protruding cylinder at the center of one end of the steel ingot 15, and the spring 14 is positioned in the assembly groove 21. The spring 14 is made of high-quality spring steel, possessing a stable elastic coefficient and maintaining good elasticity over extended periods. One end of both the spring 14 and the hydraulic cylinder 10 rests against the corresponding surfaces connecting the elongated, non-notched hydraulic square casting 12 and the elongated, non-notched hydraulic block 11. One end of the assembly groove 21, containing the steel ingot 15 and the hydraulic cylinder 10, communicates with the main shaft through hole 20 and abuts against both ends of the hinge main shaft 18. A concave positioning point 23 is provided at the center of one side of the steel ingot 15. After the glass door is closed, this concave positioning point 23 is used to position the hinge main shaft 18. This positioning method ensures that the glass door remains stable when closed and does not wobble.

[0030] Bearings 17 are sleeved at both ends of the hinge spindle 18, and these bearings 17 are fixed inside the two ends of the spindle through hole 20. The bearings 17 have good corrosion resistance and a low coefficient of friction, ensuring smooth rotation of the hinge spindle 18 and reducing energy loss. A convex positioning point 22 is provided at the center of the semi-circular surface of the hinge spindle 18. The upper and lower sides of the semi-circular surface of the spindle are inclined surfaces, facilitating the interaction between the steel ingot 15 and the spring 14 and the inclined surfaces on the semi-circular surface of the hinge spindle 18, allowing the glass door to instantly return to a certain angle. As the hinge spindle 18 rotates, the convex positioning point 22 rotates accordingly. When the glass door is closed, the convex positioning point 22 on the semi-circular surface of the hinge spindle 18 engages with the concave positioning point 23 for positioning. The other end of the hinge spindle 18 has an elliptical, flat surface. During the rotation of the hinge spindle 18, it causes the hydraulic cylinder 10 to perform a hydraulic rebound motion, allowing the glass door to return to its original position after being instantly closed to a certain angle. This is achieved through the damping hydraulic action of the hydraulic cylinder 10, ultimately making it flush with the glass door frame. This unique spindle design achieves precise control of the glass door through a clever mechanical structure.

[0031] A protective rubber strip 13 is provided on the inner side of the opening at one end of the elongated hydraulically cast 19, corresponding to the semi-circular surface of the hinge spindle 18. During the opening and closing of the glass door, the protective rubber strip 13 reduces the friction between the elongated hydraulically cast 19 and the elongated hydraulic block 11. The protective rubber strip 13 is made of wear-resistant rubber material, which has good elasticity and wear resistance, effectively reducing wear between components and extending the service life of the hinge. One side of it is attached to the semi-circular surface of the hinge spindle 18. The elastic force of the spring 14 and the damping force of the hydraulic cylinder 10 work together to achieve the slow return of the hinge.

[0032] Both the elongated, non-notch hydraulic concave casting 19 and the elongated, non-notch hydraulic square casting 12 have symmetrically arranged fixed posts 24 with internal threads at the center of their end faces. Plastic sleeves B6 and A5 are sequentially fitted onto the fixed posts 24. This combination protects the glass door from wear and sagging during use. During installation, the plastic sleeves B6 and A5 effectively distribute the pressure generated during fixing, preventing the glass door edges from cracking due to uneven stress and filling the gaps in the glass to prevent sagging. Anti-slip screws 1 are used to fix the cover panel 4, two layers of elongated, non-notch hydraulic anti-slip pads 7, the sealing plate 8, the plastic sleeves B6 and A5 to the upper end faces of the elongated, non-notch hydraulic concave casting 19 and the elongated, non-notch hydraulic square casting 12, thereby achieving clamping and fixing of both sides of the glass door and the glass door frame. The anti-slip screw 1 is made of high-strength stainless steel, which has good corrosion resistance and anti-slip properties, and can ensure a tight connection between various parts.

[0033] After the elongated hydraulic cover 2 is placed on the cover panel 4, the set bolt through the threaded hole on one side of the elongated hydraulic cover 2 is used to tighten one side of the cover panel 4, thereby fixing the elongated hydraulic cover 2 to the cover panel 4. This fixing method is simple and reliable, easy to install and disassemble, and can effectively prevent the elongated hydraulic cover 2 from loosening.

[0034] The bearings 17 at both ends of the hinge spindle 18 are fixed inside the spindle through holes 20 to ensure stable rotation of the hinge spindle 18 within the spindle through holes 20. The elongated, non-cutting hydraulically cast 19 has positioning grooves on both sides of its inner opening at one end, used to position and fix the two ends of the hinge spindle 18. The design of the positioning grooves precisely limits the movement trajectory of the hinge spindle 18, ensuring the accuracy and stability of the glass door's opening and closing.

[0035] Specifically, in use, the elongated, non-cutting hydraulic concave casting 19 and the elongated, non-cutting hydraulic square casting 12 serve as the core carriers connecting the hinge to the glass door and glass door frame. Two layers of elongated, non-cutting hydraulic anti-slip pads 7, sealing plates 8, and matching cover panels 4 are tightly fixed to their upper surfaces using anti-slip screws 1. From a mechanical perspective, this fixing method forms a stable force transmission framework. The anti-slip properties of the anti-slip pads increase the friction between the glass door and the hinge, preventing the glass door from sliding or shifting during opening and closing, and ensuring that force is accurately transmitted from the glass door to the hinge. The plastic sleeves B6 and A5, fitted onto the threaded fixing post 24, act as a "protective sleeve" during the glass door installation process. When tightening the fixing components, they effectively distribute pressure, preventing damage to the glass door due to excessive local stress. They also assist in clamping and fixing the glass door to the glass door frame, allowing the hinge to evenly transfer the weight of the glass door and the force generated during opening and closing to the glass door frame during subsequent operations, providing a stable support foundation for the normal operation of the hinge.

[0036] The elongated, non-notched hydraulic concave casting 19 and the elongated, non-notched hydraulic square casting 12 are rotatably connected by the elongated, non-notched hydraulic block 11 and the hinge spindle 18. This structure is key to the hinge's damping and buffering function. When the glass door opens or closes, the hinge spindle 18 rotates within the spindle through-hole 20 of the elongated, non-notched hydraulic block 11. During this process, the hydraulic cylinder 10, steel ingot 15, and spring 14, installed in the assembly slot 21, work together. The hydraulic oil in the hydraulic cylinder 10 flows under pressure, generating a damping force, one end of which presses against the surface of the hinge spindle 18, hindering the spindle's rotation speed. The steel ingot 15 and spring 14 assist and adjust the damping force. The spring 14 is elastic; when the hinge spindle 18 rotates, the spring 14 is compressed or stretched, storing and releasing energy, which, in conjunction with the damping force of the hydraulic cylinder 10, keeps the rotation speed of the hinge spindle 18 slow and stable. For example, when the glass door opens quickly, the hydraulic cylinder 10 and the spring 14 together generate a large resistance, slowing down the opening speed of the glass door; when the glass door closes slowly, they can provide appropriate damping force to ensure that the glass door closes smoothly and avoid damage to the glass door, glass door frame and hinges caused by the impact force generated by rapid opening and closing.

[0037] The special structural design of the hinge spindle 18 enables precise positioning and return control of the glass door. The convex positioning point 22 and the concave positioning point 23 of the steel ingot 15 act like a mechanical lock. When the glass door is closed, as the hinge spindle 18 rotates, the convex positioning point 22 accurately engages with the concave positioning point 23, restricting further rotation of the spindle and thus achieving precise positioning of the glass door, effectively preventing it from wobbling when closed. Simultaneously, the inclined surfaces of the upper and lower sides of the semi-circular plane of the hinge spindle 18, along with the steel ingot 15 and spring 14, form a clever linkage mechanism. When the glass door is closed, the spring 14 pushes the steel ingot 15 into contact with the inclined surface. Under the action of the spring force of the spring 14 and the friction between the steel ingot 15 and the inclined surface, the glass door can quickly return to a certain angle. The other end of the hinge spindle 18 has an elliptical, flat surface. During rotation, it compresses the hydraulic cylinder 10, causing the hydraulic oil inside the cylinder to flow, achieving hydraulic rebound motion. The damping force generated by this hydraulic rebound motion allows the glass door to smoothly return to its original position after being closed to a certain angle in an instant, relying on the damping hydraulic action of the hydraulic cylinder 10, until it is flush with the glass door frame. The entire process achieves precise control of the glass door's buffered closing and return.

[0038] The anti-slip strip 13, bearings 17, and the positioning groove of the elongated anti-slip hydraulic concave casting 19 work together to ensure the long-term operation of the hinge. The anti-slip strip 13, positioned at the corresponding location on the hinge spindle 18, is soft and wear-resistant. During the opening and closing of the glass door, it acts like a "lubricating film" between the elongated anti-slip hydraulic concave casting 19 and the elongated anti-slip hydraulic block 11, greatly reducing friction between them, minimizing wear, and extending the hinge's lifespan. The stainless steel bearings 17 at both ends of the hinge spindle 18 are fixed inside the spindle through-hole 20. The rolling friction of the bearings 17 is much less than the sliding friction, effectively reducing resistance during spindle rotation and making the rotation of the hinge spindle 18 smoother. Meanwhile, the positioning shaft grooves on both sides of the inner side wall of the opening of the elongated, non-cut hydraulic concave casting 19 precisely position and fix the two ends of the hinge spindle 18, limiting the radial displacement of the spindle during rotation and ensuring that the spindle always rotates on the correct track. This further ensures the reliability and stability of the hinge operation, enabling the hinge to operate stably for a long time.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
