Description

Technical Field

[0001] The utility model relates to the technical field of damping hinges, in particular to a corrosion-resistant damping hinge. Background Art

[0002] A damping hinge, also known as a hydraulic hinge, relies on a novel technology to adapt to the door's closing speed. Even when the door is forced shut, it closes gently, ensuring perfect, quiet movement. The damping hinge consists of a support, door box, buffer, connecting block, connecting rod, and torsion spring. One end of the buffer is hinged to the support; the middle of the connecting block is hinged to the support, with one end hinged to the door box and the other to the buffer's piston rod. The connecting block, connecting rod, support, and door box form a four-bar linkage. The buffer consists of a piston rod, housing, and piston. The piston is provided with through-holes and holes. When the piston rod drives the piston to move, liquid flows through the through-holes from one side to the other, thus providing a cushioning effect.

[0003] The hydraulic damper of a traditional damping hinge is usually fixed inside the support. When the hydraulic damper fails, it cannot be directly replaced and the entire damping hinge needs to be replaced. Since the two ends of the damping hinge are fixed to the cabinet door and the cabinet body by screws respectively, the secondary fixation at the same position during replacement can easily reduce the stability of the damping hinge fixation. Re-installing and fixing it in a different position can easily reduce the aesthetics of the interior of the cabinet. Therefore, a corrosion-resistant damping hinge is proposed. Utility Model Content

[0004] The purpose of the present utility model is to provide a corrosion-resistant damping hinge to solve the problem in the above background technology that the hydraulic damper of the traditional damping hinge is usually fixed inside the support. When the hydraulic damper fails, it cannot be directly replaced and the entire damping hinge needs to be replaced. Since the two ends of the damping hinge are fixed to the cabinet door and the cabinet body by screws respectively, when replacing, the secondary fixation at the same position is likely to reduce the stability of the damping hinge fixation, and the problem of re-installing and fixing in a different position is likely to reduce the aesthetics of the interior of the cabinet body.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a corrosion-resistant damping hinge, comprising a damping hinge body, a hydraulic damper installed inside the damping hinge body, an electroplating layer provided on the outer side of the damping hinge body, and a mounting assembly provided on the hydraulic damper;

[0006] The mounting assembly includes two fixing brackets, a protrusion and a guide column. The two fixing brackets are connected to the outer end of the hydraulic damper through a shaft. The bottom of the two fixing brackets is provided with a mounting groove. The protrusion is fixedly connected to the inner side of the mounting groove. The guide column is fixedly connected to the opposite side of the two fixing brackets. The outer side of the guide column is movably sleeved with a limit block. A sliding groove is provided on one side of the limit block. The guide column is slidably connected to the inside of the sliding groove. A telescopic spring is fixedly connected between the guide column and the inner side of the sliding groove.

[0007] Preferably, connecting blocks are fixedly connected to the two inner sides of the damping hinge body, and limiting grooves are provided on both sides of the connecting blocks.

[0008] Preferably, a support is fixedly connected to the inner side of the damping hinge body at one end away from the connecting block, and an elastic column is fixedly connected to the top of the support.

[0009] Preferably, one end of the two limit blocks is fixedly connected to a pull rod.

[0010] Preferably, the protrusion and the limiting block are matched with the limiting groove respectively, and the protrusion and the limiting block are respectively in contact with the inside of the limiting groove.

[0011] Preferably, the mounting groove and the connecting block match each other, and the connecting block is snapped into the interior of the mounting groove.

[0012] Compared with the prior art, the utility model adopts the above technical solution and has the following technical effects: the utility model moves by pulling the pull rod backward, so that one end of the limit block is disengaged from the limit groove on one side of the connecting block. At this time, the hydraulic damper can be pulled upward to make the fixing frame on the hydraulic damper disengage from the outside of the connecting block, and then the hydraulic damper is disengaged from the inside of the elastic column. At this time, the hydraulic damper can be disengaged, and then the bolts connected to the piston rod end of the hydraulic damper can be disassembled to complete the disassembly of the hydraulic damper. The hydraulic damper can be replaced without disassembling and replacing the damping hinge body, which facilitates maintenance of the damping hinge body. BRIEF DESCRIPTION OF THE DRAWINGS
