Damping hinge is a kind of hinge that is relatively easy to use. It mainly uses liquid buffering performance to work, and its buffering effect is very ideal. For example, if the door is used with a damped hinge, when the door is opened within a range of 60°, under the condition of no external force, the door will slowly begin to close slowly under the action of the damping hinge, and basically no impact will be generated. Therefore, whether it is for the safety of the door or to create a quiet indoor environment is very helpful.
Damping hinges, also known as hydraulic hinges, can achieve gentle closures, guaranteeing perfect movement and softness. Its composition includes bearings, connecting blocks, connecting rods, buffers, door boxes and torsion springs, and has a wide applicability, such as wardrobes, cabinets, floor cabinets, wine cabinets, bookcases, TV cabinets, lockers and other furniture. Damping hinges can be used for connection.
Damping hinges have a long service life, and their opening and closing times can reach more than 50,000 times. Responsive, it will shut down slowly in 4-6 seconds. No maintenance is required, and there will be no deflation or oil leakage when subjected to destructive force pushing.
Second, the damping hinge purchase skills
1, look at the surface
Want to pick a good product, the appearance of the performance is very basic, at the time of purchase, look at how the damping hinge surface material leveling, if there are scratches, deformation and other issues, do not choose, this is generally With the secondary processing of waste products, not only the appearance of ugly, no grade, quality is not guaranteed.
2, see the hydraulic performance
The most important thing about the hinge is its switching function. The damping hinge belongs to the hydraulic hinge. This requires even higher requirements for the switch. It can check its damper, rivet assembly, etc. It also depends on whether or not noise is generated during closing. Even if the speed is even, there are some minor problems that are not good.

Damping hinge
A dumbwaiter is a small freight elevator or lift intended to carry objects rather than people. Dumbwaiters found within modern structures, including both commercial, public and private buildings, are often connected between multiple floors. When installed in restaurants, schools, kindergartens, hospitals, retirement homes or in private homes, the lifts generally terminate in a kitchen.
The term seems to have been popularized in the United States in the 1840s, after the model of earlier "dumbwaiters" now known as serving trays and lazy Susans. The mechanical dumbwaiter was invented by George W. Cannon, a New York City inventor. Cannon first filed for the patent of a brake system (US Patent no. 260776) that could be used for a dumbwaiter on January 6, 1883. Cannon later filed for the patent on the mechanical dumbwaiter (US Patent No. 361268) on February 17, 1887.Cannon reportedly generated a vast amount of royalties from the dumbwaiter patents until his death in 1897.
A simple dumbwaiter is a movable frame in a shaft, dropped by a rope on a pulley, guided by rails; most dumbwaiters have a shaft, cart, and capacity smaller than those of passenger elevators, usually 45 to 450 kg (100 to 1000 lbs.) Before electric motors were added in the 1920s, dumbwaiters were controlled manually by ropes on pulleys.
Early 20th-century codes sometimes required fireproof dumbwaiter walls and self-closing fireproof doors and mention features such as buttons to control movement between floors and locks on doors preventing them from opening unless the cart is stopped at that floor. Dumbwaiter Lifts in London were extremely popular in the houses of the rich and privileged. Maids would use them to deliver laundry to the laundry room from different rooms in the house. They negated the need to carry handfuls of dirty washing through the house, saving time and preventing injury.
A legal complaint about a Manhattan restaurant's dumbwaiter in 1915, which also mentions that food orders are shouted up and down the shaft, describes its operation and limitations as follows:
[There is] ... great play between the cart of the dumb-waiter and the guides on which it runs, with the result that the running of the cart is accompanied by a loud noise. The rope which operates the cart of the dumb-waiter runs in a wheel with a very shallow groove, so that the rope is liable to and does at times slip off. ... The cart has no shock absorbers at the top, so that when it strikes the top of the shaft or wheel there is a loud report. ... [T]he ropes of the dumb-waiter strike such wall at frequent intervals with a loud report. ... [T]he dumb-waiter is often negligently operated, by running it faster than necessary, and by letting it go down with a sudden fall.
More recent dumbwaiters can be more sophisticated, using electric motors, automatic control systems, and custom freight containers of other kinds of elevators. Recently constructed book lifts in libraries and mail or other freight transports in office towers may be larger than many dumbwaiters in public restaurants and private homes, supporting loads as heavy as 450 kg (990lbs)
