Abstract

A kind of adjustable damping device, is related to damping shock absorption field.The upper end of piston rod is stretched out from the upper end of cylinder body and is connected with upper binding head, the cylindrical cavity of cylinder body carries oil duct, the inner cap being threadedly coupled with cylinder body cylindrical cavity is located in the middle part of piston rod, the space that inner cap is formed with cylinder body cylindrical cavity is full of damping fluid, piston-rod lower end is equipped with enclosing cover, and spring is provided between enclosing cover and inner cap, and lower union joint is threadedly coupled with cylinder body, it is provided with spring between enclosing cover and lower union joint, adjusting screw is carried on boss on the outside of cylinder body.The utility model piston rod does straight reciprocating motion together with enclosing cover in the cylindrical cavity of cylinder body, and damping fluid is flowed back and forth by oil duct, so as to produce damping, consumed energy;When turning adjusting screw, the head of adjusting screw makes the sectional area of oil duct change, and caused damping force also changes;The utility model is simple in construction, eliminates pressure accumulater, and the spring at enclosing cover both ends makes to be provided with reset function during damper two-way function.

Description

Adjustable damping device
Technical field
Damping shock absorption technical field is the utility model is related to, specifically a kind of adjustable damping device.
Background technology
Damper is a kind of device for being placed in and the resistance of motion being provided on structural system, for depletion kinergety, It is widely used in space flight, aviation, military project, firearms, automobile and other industries.Generally, the hydraulic cylinder piston inside damper is by piston When bar is with movement, the volume of chamber changes, it is necessary to which pressure accumulater compensates to volume before and after piston, and structure is more complicated, And the damping size of damper is fixed, application is limited.
The content of the invention
For overcome the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of adjustable damping device, taken Disappeared pressure accumulater, has and damps adjustable and reset function.
For achieving the above object, the upper end of the utility model piston rod is stretched out and and upper binding head from the upper end of cylinder body Connection, the cylindrical cavity of cylinder body carry oil duct, and the inner cap being threadedly coupled with cylinder body cylindrical cavity is located at the middle part of piston rod, The space that inner cap is formed with cylinder body cylindrical cavity is full of damping fluid, and the lower end of piston rod is equipped with enclosing cover, between enclosing cover and inner cap Provided with spring, lower union joint is threadedly coupled with cylinder body, is provided with spring between enclosing cover and lower union joint, band on the outside boss of cylinder body There are adjusting screw, turning adjusting screw, the head of adjusting screw makes the sectional area of oil duct change.
Sealing ring one is provided between the bottom of the adjusting screw and cylinder body.
Sealing ring two and wear ring are provided between the upper end of the cylinder body and piston rod;It is provided between inner cap and piston rod close Seal two and wear ring.
The cylinder body, which is provided with, to carry out spacing step to the head of adjusting screw.
Compared with prior art, piston rod does linear reciprocation to the utility model together with enclosing cover in the cylindrical cavity of cylinder body Motion, the damping fluid between inner cap and cylinder body cylindrical cavity are flowed back and forth by oil duct, so as to produce damping, consumed energy; When turning adjusting screw, the head of adjusting screw makes the sectional area of oil duct change, and caused damping force also changes; The utility model is simple in construction, eliminates pressure accumulater, and the spring at enclosing cover both ends makes to be provided with resetting during damper two-way function Function.
Brief description of the drawings
Fig. 1 is structure diagram of the present utility model.
Fig. 2 is Fig. 1 A-A sectional views.
Fig. 3 is enlarged drawing at Fig. 2 I.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the upper end of the utility model piston rod 2 stretched out from the upper end of cylinder body 3 and with upper connection First 1 connection, is provided with sealing ring 2 11 and wear ring 12 between the upper end of the cylinder body 3 and piston rod 2;In the cylinder of cylinder body 3 Chamber carries oil duct 13, and the inner cap 7 being threadedly coupled with the cylindrical cavity of cylinder body 3 is located at the middle part of piston rod 2, inner cap 7 and piston rod 2 Between be provided with sealing ring 2 11 and wear ring 12, the space that inner cap 7 is formed with the cylindrical cavity of cylinder body 3 is full of damping fluid 6;Piston The lower end of bar 2 is equipped with enclosing cover 10, and spring 9 is provided between enclosing cover 10 and inner cap 7, and lower union joint 8 is threadedly coupled with cylinder body 3, enclosing cover Spring 9 is provided between 10 and lower union joint 8;Adjusting screw 4, the bottom of the adjusting screw 4 are carried on the outside boss of cylinder body 3 Sealing ring 1 is provided between cylinder body 3, turning adjusting screw 4, the head of adjusting screw 4 changes the sectional area of oil duct 13 Become, cylinder body 3 is provided with step 14, the head of adjusting screw 4 can be carried out spacing.
Piston rod 2 of the present utility model does straight reciprocating motion, inner cap together with enclosing cover 10 in the cylindrical cavity of cylinder body 3 Damping fluid 6 between 7 and the cylindrical cavity of cylinder body 3 is flowed back and forth by oil duct 13, so as to produce damping, consumed energy;Work as rotation When turning adjusting screw 4, the head of adjusting screw 4 makes the sectional area of oil duct 13 change, and caused damping force also changes; The spring 9 at the both ends of enclosing cover 10 makes to be provided with reset function during damper two-way function.
