And external door；Divide according to material, door can be divided into timber, steel casement door, aluminium alloy door, plastic door, iron gate, stainless steel door etc.；From door
Effect on for, door can be mainly divided into gate, entering house door, interior door, explosion proof door, blast-resistant door, fire resistant doorsets and be not easy to crush
Safety door.
Damper, it is to provide the resistance of motion, the device of depletion kinergety.In space flight, aviation, military project, firearms, vapour
Carry out vibration damping energy dissipating using various dampers (or damper) already in the industries such as car.After nineteen seventies,
People start step by step to be converted in the Structural Engineerings such as building, bridge, railway these technologies, and its development is very rapid.Especially
It is the hydraulic pressure viscous damper for having more than 50 years history, before being received in the U.S. by Structural Engineering circle, experienced many experiments, sternly
Lattice examine, prove repeatedly, particularly the lengthy procedure of earthquake test.But existing damper structure is complicated, volume is more heavy,
Sealing property is general, and muting function is poor, and this just brings inconvenience for the use of people.
Utility model content
The purpose of this utility model is to provide a kind of damper, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of damper, including connector, piston rod, guide sleeve, spacer, piston, spring and cylinder body, the guide sleeve,
Spacer and piston are enclosed on the outside and guide sleeve of piston rod, spacer and piston are arranged in order from top to bottom, connector installation
At the top of piston rod, the first O-ring and pad are installed on guide sleeve, the second O-ring is installed in the middle part of piston, for storing
The cylinder body of damping oil is located at bottommost, and spring is arranged in cylinder body and the upper end of spring and the bottom connection of piston touch.
As further program of the utility model：Piston rod is made using stainless steel material, connector, guide sleeve, pad
Piece and spacer are made using plastic material, and the first O-ring and the second O-ring are made using silica gel or elastomeric material.
As further program of the utility model：Sponge for absorbing superfluous damping oil is installed inside spacer, led
To the internal Y-shaped ring being provided with for interior sealing of set.
Compared with prior art, the beneficial effects of the utility model are：The product is cooperated by piston and sealing ring
Effect, make the limited outflow of damping oil flow in cylinder body, so as to obtain corresponding damping force, reach provide motion resistance,
The purpose of depletion kinergety, plays damping and Jing Yin effect, and the guide sleeve of setting can ensure the concentric of piston rod well
Degree and the sealing to cylinder body, using effect are good；The product design is reasonable, simple in construction, and braking is steady, and there is good market to push away
Wide property, is applicable not only to door, applies also for the fields such as furniture, household electrical appliances, machinery.
