Description

Technical Field

[0001] This utility model relates to the technical field of hinge design, specifically to a pull-out hinge assembly for cabinet doors. Background Technology

[0002] A hinge, also known as a door hinge, is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges can consist of movable components or be made of foldable materials. Hinges are mainly installed on doors and windows, while hinges are more commonly installed on cabinets. They are mainly classified by material into stainless steel hinges and iron hinges. To provide a better user experience, hydraulic hinges (also known as damping hinges) have emerged. Their characteristic is a buffering function when the cabinet door closes, minimizing the noise generated by the door colliding with the cabinet body.

[0003] Currently, most server racks for electrical equipment use hinges for opening and closing. However, the internal electrical equipment needs frequent replacement, and the hinges may wear down due to frequent opening and closing, causing them to loosen and affecting the alignment and closing of the door. Therefore, there is an urgent need to design a pull-out hinge assembly for server rack doors to solve these problems. Summary of the Invention

The two ends of the second connecting plate are movably connected to the first connecting plate and the movable block, respectively. A mounting seat is provided on one side of the movable block. A sliding groove for assisting the movable block to move is formed on the surface of the mounting seat. The movable block is slidably connected inside the sliding groove. The width of the sliding groove is adapted to the size of the movable block.

[0006] By adopting the above-mentioned utility model, the hinge component can assist the cabinet door in opening and closing operations after the structure is installed. During the opening and closing process, the moving block can move synchronously with the cabinet door along the sliding groove as the cabinet door moves, so that the cabinet door opening and closing operation can be smoother. Moreover, the sliding groove in the mounting base is only used to assist the moving block in moving, ensuring that the wear and tear on the components during frequent opening and closing is greatly reduced, and the overall service life of the structure is greatly improved.

[0007] Preferably, both sides of the sliding groove are provided with moving grooves, the surface of the moving block is provided with holes, a movable shaft is movably installed inside the holes, the two ends of the movable shaft are engaged inside the moving groove, and the size of the two ends of the movable shaft is adapted to the width of the moving groove.

[0008] By adopting the above-mentioned utility model, the movable shaft can move along the sliding groove, which can assist the moving block to move synchronously along the sliding groove, making the opening and closing operation of the cabinet door smoother.

[0009] Preferably, the hinge component further includes a threaded pin, which is threadedly connected to the connecting end of the first connecting plate, the second connecting plate and the moving block, and an auxiliary nut is threadedly connected to the end of the threaded pin.

[0010] By adopting the above-mentioned utility model, the threaded pin is used to assist the first connecting plate, the second connecting plate and the moving block in adjusting the angle, so as to assist the cabinet door in opening and closing.

[0011] Preferably, the surface of the base is provided with a groove, the size of which is adapted to the size of the first connecting plate, and a main shaft is movably installed inside the groove, and the other end of the first connecting plate is movably connected to the surface of the main shaft.

[0012] By adopting the above-mentioned utility model, during the closing process, the first connecting plate can be inserted into the groove along the main shaft for easy storage, thereby saving some space inside the cabinet and making it convenient for small cabinet units to use.

[0013] Preferably, a first mounting plate is fixedly installed on one side of the base, and the surface of the first mounting plate is provided with a mounting hole, and a first threaded rivet is threadedly connected to the inside of the mounting hole.

[0014] By adopting the above-mentioned utility model, the first mounting plate is used to assist the base in fixing inside the cabinet, which facilitates installation.

[0015] Preferably, a second mounting plate is fixedly installed on both sides of the bottom of the mounting base, and a positioning hole is opened on the surface of the second mounting plate, and a second threaded rivet is threaded into the internal thread of the positioning hole.

[0016] By adopting the above-mentioned utility model, the second mounting plate at the bottom of the mounting base can assist the mounting base in connecting to the cabinet door, so as to facilitate subsequent opening and closing operations.

[0017] In the above technical solution, the pull-out hinge assembly for cabinet doors provided by this utility model has the following advantages: The cabinet door uses a pull-out hinge assembly. Through the hinge component, the cabinet door can be opened and closed after the structure is installed. During the opening and closing process, the moving block can move synchronously with the cabinet door along the sliding groove as the cabinet door moves, so that the cabinet door can be opened and closed more smoothly. Moreover, the sliding groove in the mounting base is only used to assist the moving block to move, ensuring that the wear and tear on the component during frequent opening and closing is greatly reduced, and the overall service life of the structure is greatly improved.
