Description

Technical Field

[0001] This utility model relates to the technical field of hinges, specifically a hinge with a buffer function. Background Technology

[0002] Hinges occupy an important position in furniture hardware. They are mechanical devices used to connect two solid objects and allow them to rotate relative to each other. Hinges are more commonly used in large cabinets such as doors and windows, cabinets, electromechanical cabinets, heavy-duty cold storage, and freezers.

[0003] The structure of existing hinges generally includes a base installed on the door, a fixed seat installed on the frame, and a transmission component hinged between the base and the fixed seat. The transmission component enables the base to open and close on the fixed seat, thereby enabling the door to open and close on the frame.

[0004] Currently, for ease of use, hinges, especially those used for heavy-duty cabinet doors, are equipped with an automatic closing device. When closed at a certain angle, the hinge automatically closes under the power of the device, making operation convenient.

[0005] However, the hinge structure described above has the following shortcomings in practical applications: 1) Existing hinges and automatic closing devices generally use automatic closing springs with large elastic force, especially for heavy-duty doors and cabinets. When closing, the automatic closing of the door under the action of large elastic force is prone to impact, generating large noise, reducing the user experience, and may even damage the product.

[0006] 2) Existing hinges have complex transmission structures, poor transmission stability, and limited opening range, resulting in significant limitations in their use. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hinge with a buffer function. It has a simple structure, a buffer function, high transmission stability, is practical and reliable, greatly improves the user experience, and ensures the opening range of the product and the quality of product use.

[0008] The objective of this invention is achieved as follows: A hinge with a buffer function includes a fixed seat and a base. A transmission linkage assembly for opening and closing the fixed seat on the base is hinged between the fixed seat and the base. The transmission linkage assembly is provided with a buffer component for buffering when closed. The buffer component includes a buffer damper and a damping movable push rod assembly. One movable end of the damping movable push rod assembly is hinged to the fixed seat, and the other movable end of the damping movable push rod assembly is hinged to the transmission arm of the transmission linkage assembly. The cylinder of the buffer damper is installed at one movable end of the damping movable push rod assembly, and the piston rod of the buffer damper is installed at the other movable end of the damping movable push rod assembly.

[0009] Based on the above optimization, the damping movable push rod assembly includes a first damping push rod and a second damping push rod. The positioning end of the first damping push rod is hinged to the fixed seat, and the movable end of the first damping push rod is slidably connected to the positioning end of the second damping push rod. The positioning end of the second damping push rod is hinged to the transmission arm, and the movable end of the second damping push rod is slidably connected to the positioning end of the second damping push rod. The cylinder of the buffer damper is fixedly connected to the movable end of the second damping push rod, and the piston rod of the buffer damper is fixedly connected to the movable end of the first damping push rod.

[0010] Based on the above optimization, the movable ends of the first damping push rod and the second damping push rod are respectively equipped with a first sliding shaft and a second sliding shaft. The first sliding shaft is slidably connected to the positioning end of the second damping push rod, and the second sliding shaft is slidably connected to the positioning end of the first damping push rod. The cylinder of the buffer damper is mounted on the second sliding shaft, and the push rod of the buffer damper is mounted on the first sliding shaft.

[0011] Based on the above optimization, the positioning end of the first damping push rod and the positioning end of the second damping push rod are respectively provided with a first limiting groove and a second limiting groove. The first limiting groove is slidably connected to a second sliding shaft, and the second limiting groove is slidably connected to a first sliding shaft.

[0012] Based on the above optimization, the transmission linkage assembly includes a transmission arm, a connecting arm, a transmission rod, and a connecting rod. The positioning ends of the transmission arm and the transmission rod are hinged to the fixed base, and the swinging end of the transmission rod is hinged to the middle of the connecting rod. The positioning ends of the connecting rod and the connecting arm are respectively located in the middle and swinging parts of the transmission arm. The swinging parts of the connecting arm and the connecting rod are respectively hinged to the base, so that the transmission linkage assembly forms a four-bar linkage assembly hinged between the fixed base and the base. The damping movable push rod assembly is located inside the transmission arm.

[0013] Based on the above optimization, the fixed seat is equipped with a positioning damping rotary seat, the transmission arm shaft is equipped with a connecting damping rotary seat, the positioning damping rotary seat shaft is connected to a first damping push rod, and the connecting damping rotary seat shaft is connected to a second damping push rod.

[0014] Based on the above optimization, one side of the base is stamped with mounting ears for easy assembly.

[0015] The advantages of this utility model are: 1) The buffer assembly using this structure, including the buffer damper, the damping movable push rod assembly, the fixed seat, the base, and the transmission linkage assembly, works in conjunction with each other. When closing, the base drives the transmission linkage assembly to fold while simultaneously pushing the damping movable push rod assembly to slide and compress, thus activating the buffer damper. This causes the base to slowly fold onto the fixed seat, allowing the product door to close slowly on the cabinet, reducing noise generation, ensuring reliability and practicality, and enhancing the user experience.

[0016] 2) The damping movable push rod assembly with this structure is simple in structure and easy to assemble. When opening, the base drives the transmission rod assembly to unfold at the same time as the damping movable push rod assembly unfolds. When the transmission rod assembly is fully unfolded, the buffer damper is reset, ensuring that the door opens smoothly and stably, and ensuring the quality of product use.

[0017] 3) The transmission linkage assembly with this structure has high transmission stability, can improve the opening range, and facilitates the use of the product. Attached Figure Description

[0027] The present invention will now be further described with reference to the accompanying drawings.

[0028] According to the appendix Figures 1 to 9As shown, the hinge with buffering function of this utility model includes a fixed base 1 and a base 2. A transmission linkage 3 is hinged between the fixed base 1 and the base 2 for opening and closing the fixed base 1 on the base 2. The transmission linkage 3 is provided with a buffer component for buffering when closed. The buffer component includes a buffer damper 4 and a damping movable push rod assembly 5. One movable end of the damping movable push rod assembly 5 is hinged to the fixed base 1, and the other movable end of the damping movable push rod assembly 5 is hinged to the transmission arm 31 of the transmission linkage 3. The cylinder of the buffer damper 4 is installed at one movable end of the damping movable push rod assembly 5, and the piston rod of the buffer damper 4 is installed at the other movable end of the damping movable push rod assembly 5.

[0029] The buffer assembly using this structure, consisting of a buffer damper 4, a damping movable push rod assembly 5, a fixed base 1, a base 2, and a transmission linkage assembly 3, works in conjunction with these components. When closing, the base 2 drives the transmission linkage assembly 3 to fold while simultaneously pushing the damping movable push rod assembly 5 to slide and compress, thus activating the buffer damper 4. This causes the base 2 to slowly fold onto the fixed base 1, allowing the product door to close slowly on the cabinet, reducing noise generation, ensuring reliability and practicality, and enhancing the user experience.

[0030] Reference Figures 1 to 9 As shown, further detailed, the damping movable push rod assembly 5 includes a first damping push rod 51 and a second damping push rod 52. The positioning end of the first damping push rod 51 is hinged to the fixed base 1, and the movable end of the first damping push rod 51 is slidably connected to the positioning end of the second damping push rod 52. The positioning end of the second damping push rod 52 is hinged to the transmission arm 31, and the movable end of the second damping push rod 52 is slidably connected to the positioning end of the second damping push rod 52. The cylinder of the buffer damper 4 is fixedly connected to the movable end of the second damping push rod 52, and the piston rod of the buffer damper 4 is fixedly connected to the movable end of the first damping push rod 51.

[0031] In practical applications, the movable ends of the first damping push rod 51 and the second damping push rod 52 are respectively equipped with a first sliding shaft 53 and a second sliding shaft 54. The first sliding shaft 53 is slidably connected to the positioning end of the second damping push rod 52, and the second sliding shaft 54 ​​is slidably connected to the positioning end of the first damping push rod 51. The cylinder of the buffer damper 4 is mounted on the second sliding shaft 54, and the push rod of the buffer damper 4 is mounted on the first sliding shaft 53.

[0032] The positioning end of the first damping push rod 51 and the positioning end of the second damping push rod 52 are respectively provided with a first limiting groove 55 and a second limiting groove 56. The first limiting groove 55 is slidably connected to a second sliding shaft 54, and the second limiting groove 56 is slidably connected to a first sliding shaft 53.

[0033] When closed, the base 2 drives the transmission linkage 3 to fold inward, causing the first damping push rod 51 and the second damping push rod 52 to retract inward respectively. This causes the first sliding shaft 53 and the second sliding shaft 54 ​​to slide inward along the second limiting groove 56 and the first limiting groove 55 respectively, thereby driving the buffer damper 4 to work and transmitting its damping effect to the base 2, causing the base 2 to fold inward slowly and evenly, thus realizing the product's closed buffer function.

[0034] When opened, the base 2 drives the transmission linkage 3 to unfold outward, causing the first damping push rod 51 and the second damping push rod 52 to extend outward respectively, so that the first sliding shaft 53 and the second sliding shaft 54 ​​slide outward along the second limiting groove 56 and the first limiting groove 55 respectively, so that the buffer damper 4 can be reset, making it easier for the transmission linkage 3 to open completely outward, realizing the smooth and stable opening of the door, while ensuring that the opening range is not affected, thus improving the quality of product use.

[0035] Reference Figures 1 to 9 As shown, further detailed, the transmission linkage group 3 includes a transmission arm 31, a connecting arm 32, a transmission rod 33, and a connecting rod 34. The positioning ends of the transmission arm 31 and the transmission rod 33 are hinged to the fixed base 1, and the swinging end of the transmission rod 33 is hinged to the middle of the connecting rod 34. The positioning ends of the connecting rod 34 and the connecting arm 32 are respectively connected to the middle and swinging parts of the transmission arm 31. The swinging parts of the connecting arm 32 and the connecting rod 34 are respectively hinged to the base 2, so that the transmission linkage group 3 forms a four-bar linkage group hinged between the fixed base 1 and the base 2. The damping movable push rod group 5 is provided inside the transmission arm 31.

[0036] The transmission linkage group 3 with this structure has high transmission stability, can improve the opening range, and facilitates the use of the product.

[0037] Furthermore, the fixed base 1 is equipped with a positioning damping rotary seat 6, and the transmission arm 31 is shaft-mounted with a connecting damping rotary seat 7. The positioning damping rotary seat 6 is shaft-connected to a first damping push rod 51, and the connecting damping rotary seat 7 is shaft-connected to a second damping push rod 52. The structure is simple, assembly is convenient, and it improves the transmission stability of the transmission linkage group 3, making it reliable and practical.

[0038] Furthermore, one side of the base 2 is stamped with a mounting lug 8 for easy assembly. This simplifies the structure, facilitates hinge assembly, and makes disassembly and maintenance convenient.
