Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically to a rebound damping hydraulic hinge structure for furniture cabinet doors. Background Technology

[0002] With the advent of the Industrial Revolution, hinge manufacturing technology was greatly improved, and its application areas gradually expanded. From the late 19th to the early 20th century, with the development of the steel industry, hinge manufacturing processes were further optimized, resulting in various types of hinges, such as sliding hinges and swivel hinges. Entering the mid-20th century, the hinge industry ushered in a period of rapid development.

[0003] As disclosed in patent application CN 216841123 U, a rebound-type damping hydraulic hinge structure includes a bottom shell. A control device is installed inside the bottom shell. The control device includes a first internal movable component, a second internal movable component movably connected to the bottom of the first internal movable component, and a hydraulic rod movably connected to the bottom of the second internal movable component. A damping hydraulic pipe is provided at the bottom of the hydraulic rod, and bottom fixing rods are fixedly connected to both sides of the damping hydraulic pipe. This utility model relates to the field of damping hinge technology. This rebound-type damping hydraulic hinge structure, through a connecting rod, drives the second internal movable component to move forward upwards. An internal spring applies a supporting force to the connecting rod. Under the action of the supporting force, the second internal movable component moves forward upwards, and through a bottom insert rod, drives the hydraulic rod downwards, thus closing the door. Compared to traditional damping hydraulic hinges that use a buffer to close the cabinet door, this structure achieves a rebound-type buffer opening of the cabinet.

[0004] However, in the existing technology CN 216841123 U, there is a rebound damping hydraulic hinge structure. This device does not have an elastic locking mechanism. The operator cannot disassemble the device simply by pressing the movable block. The conventional disassembly method is relatively troublesome and does not facilitate the operator to quickly disassemble and replace the damaged components. The cost of replacing the whole device increases significantly. Utility Model Content

[0005] The purpose of this utility model is to provide a rebound-type damping hydraulic hinge structure for furniture cabinet doors, so as to solve the problem that the above-mentioned device does not have an elastic locking mechanism, and the operator cannot disassemble the device by simply pressing the movable block. The conventional disassembly method is relatively troublesome and not conducive to the operator to quickly disassemble and replace the damaged components, resulting in a significant increase in cost when replacing the whole device.

[0006] To achieve the above objectives, this utility model provides a rebound-type damping hydraulic hinge structure for furniture cabinet doors.

[0007] The device includes a fixed frame with two movable slots on one side inside. An elastic clamping mechanism is movably mounted inside each movable slot. The elastic clamping mechanism includes a telescopic spring, a telescopic rod, a movable block, and a moving groove. A telescopic spring is fixedly mounted inside each movable slot, and a telescopic rod is fixedly mounted inside each telescopic spring. A movable block is movably mounted on one side of each telescopic spring, and one end of the telescopic rod is fixedly connected to the movable block. Moving grooves are located at both ends of one side of the fixed frame, and these moving grooves are movably connected to the movable blocks. A groove is located on one side inside the fixed frame, and a movable rod is movably mounted on one side inside the groove. A mounting block is located outside the movable rod, and a damper is fixedly mounted on one side of the mounting block.

[0008] The fixing frame has connecting blocks fixedly installed on both sides. The connecting blocks have through holes on both sides inside. The first fixing screw is movably installed inside the through hole. The mounting blocks on both sides of the fixing frame are fixed inside the cabinet by rotating the first fixing screw to ensure its stability when rotating.

[0009] The fixed frame has a fixed plate movably mounted on one side, and annular holes are opened on both sides of the fixed plate. The annular holes are movably connected to the movable block. A support plate is fixedly mounted on the bottom of the fixed plate. The annular holes on both sides inside the fixed plate are movably connected to the movable block, which allows the fixed frame to rotate and also facilitates the disassembly and replacement of the fixed frame.

[0010] A vertical rod is provided on one side inside the groove, and a spring is fixedly installed on the outside of the vertical rod. One end of the spring is movably connected to the movable rod, and the movable rod can buffer the force during rotation with the cooperation of the spring.

[0011] The fixing plate has a connecting plate fixedly installed on one side, and the connecting plate has second fixing screws fixedly installed on both sides. Rotating the second fixing screws will fix the connecting plate to the outside of the mounting plate, thus achieving the function of connection and fixation.

[0012] All mounting plates are fixedly installed on the other side of the connecting plate. Several third fixing screws are fixedly installed on both sides of the mounting plate. The third fixing screws pass through the mounting plate and are movably connected to the cabinet door to ensure stability during rotation.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This furniture cabinet door uses a rebound-type damping hydraulic hinge structure. The device first connects the third fixing screw to the cabinet door through the mounting plate. Then, the second fixing screw is rotated to fix the connecting plate to the outside of the mounting plate. The mounting blocks on both sides of the external mounting frame are fixed to the inside of the cabinet by rotating the first fixing screw. After installation, if the spring on one side of the cabinet door mounting frame is rotated, it will compress the movable rod and cause elastic deformation. The movable rod drives the mounting block to move, and hydraulic buffering is performed under the action of the damper. This device has a rebound-type damping hydraulic structure, which can reduce the impact force.

[0014] This type of furniture cabinet door uses a rebound-type damping hydraulic hinge structure. If the operator needs to disassemble or replace the fixing frame, they can manually press the movable blocks on both sides of the fixing frame. The movable blocks move inward along the moving groove, squeezing the telescopic spring and causing it to elastically deform. Under the limiting cooperation of the telescopic rod, the movable blocks elastically retract and disengage from the annular hole, completing the disassembly. Similarly, during installation, the elastic recovery is used for locking and fixing. With the setting of the elastic locking mechanism, the operator only needs to press the movable block to separate the fixing frame. The operation is simple and convenient, and it is also conducive to the operator to quickly disassemble and replace damaged components. The replacement of partial parts controls the cost to a certain extent. Attached Figure Description
