The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
A kind of quick lock in damper, it comprises resistance cylinders 1, piston rod 2.1 and the piston head 3 that is filled with hydraulic oil 8, piston rod 2.1 one end are passed resistance cylinders 1 and are connected with mount pad 6, the other end of piston rod 2.1 stretches out resistance cylinders 1 and is connected with piston rod connector 9, piston head 3 radially seals and is arranged in resistance cylinders 1, piston head 3 is divided into resistance cylinders 1 left cavity 4.1 and the right cavity 4.2 of mutual connection, at left cavity 4.1 and right cavity 4.2, only can circulate by being provided with the passage of quick lock in valve piece, this pressure-control valve is one way valve.
In the present embodiment:
Between the radially two ends of piston head 3 and resistance cylinders 1, be provided with seal 2.2, seal 2.2 can be the sealing devices such as sealing ring, in order to guarantee that left cavity 4.1 and right cavity 4.2 keep apart completely.
Embodiment mono-: piston head 3 offers two through holes 10 along axis, through hole 10 be take the central axis of piston head 3 and is symmetrical arranged as axis of symmetry, at each, be equipped with built-in quick lock in valve piece 11 in by 10, built-in quick lock in valve piece 11 is built-in one way valve, in valve piece, being equipped with somely to rightabout valve ball 11.1 is set, is a loop when hydraulic oil 8 flows between left cavity 4.1 and right cavity 4.2 like this.
Embodiment bis-: between left cavity 4.1 and right cavity 4.2, by external interface channel 5, connect, in interface channel 5, be provided with external quick lock in valve piece 7, external quick lock in valve piece 7 is external one way valve, the valve ball 7.2 that the two ends of this external one way valve are provided with two valves 7.1 and coordinate with valve 7.1, is provided with spring 7.3 between valve ball 7.2.
When quick lock in valve piece is during in circulation status, resistance cylinders 1 internal pressure is identical.When damper is subject to slow displacement control (temperature movement), the interior hydraulic flow rates of resistance cylinders 1 is less than quick lock in valve piece setting value, and ball valve can normally move but can not block valve; When the interior hydraulic flow rates of resistance cylinders 1 is greater than quick lock in valve piece setting value, ball valve locking, damper locking.
V1 * S1=V2 * S2, wherein V1 is quick lock in valve flow, V2 is damper flow, S1 is quick lock in valve communication port sectional area, S2 is dampener hydraulic chamber sectional area, from above formula, quick lock in device lock-up valve flow and damper cylinder body and lock-up valve sectional area ratio are proportional, when cylinder body moves, lock damping port hydraulic flow and flow velocity amplify in proportion, pressure promotes ball valve and overcomes fast spring setup pressure value and block valve, makes quick lock in damper have high speed lock function.
The utility model adopts hydraulic oil 8 and quick lock in valve piece as main bearing member, at building, be subject to external force and start to be subjected to displacement driving lock-up valve Fast Block closed, make moving point can become fast anchoring point, reach lock designing requirement, simultaneously under low-speed motion is controlled, ball valve cannot be blocked valve all the time, thereby can transmit normally low speed displacement; Compare with conventional damper, quick lock in damper has adjusting function faster.
The above, be only preferred embodiment of the present utility model, not the utility model structure done to any pro forma restriction.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of the technical solution of the utility model.
