Abstract

The utility model provides an adjustable damper which comprises a damper; the damper comprises an outer bushing, an inner bushing and a torsion spring; the two ends of the torsion spring are separated connected with the outer bushing and the inner bushing; the utility model is characterized in that the damper also comprises an adjustable device and the adjustable device comprises a worm and a worm wheel; the worm wheel is connected with the outer bushing of the damper and the worm wheel is meshed with the worm; the worm rotates and drives the outer bushing to rotate by the worm wheel and the rotation of the outer bushing changes the torque of the torsion spring. The utility model has the beneficial effects that a screw driver is used for rotating the worm in clockwise direction to push the worm wheel to rotate along the worm shaft to drive the torsion spring to retract in radial direction and increase the torque. At the same time, people can observe the outer bushing scale until the scale reaches the ideal one and then the worm wheel is automatically locked by the worm; in this way, the requirements of adjusting rotation angle, speed and torque until the ideal value is reached can be met.

Description

Adjustable damper

Technical field

The utility model relates to a kind of damper, relates in particular to a kind of adjustable damper.

Background technique

At present general damping device speed is fixed and non-adjustable, and can only do the rough calculation adjusting before installation, and often the size of the speed of speed, angle of revolution and moment of torsion all is difficult to control to ideal value, more cannot say for sure to demonstrate,prove conformity in batch process.

The model utility content

The purpose of this utility model is to provide a kind of adjustable damper, is intended to solve the nonadjustable problem of moment of torsion of the damper that exists in the prior art.

The utility model is to realize like this, a kind of adjustable damper, comprise damper, described damper comprises overcoat, interior cover and torque spring, described torque spring two ends connect described overcoat and interior cover respectively, described adjustable damper also comprises adjusting device, described adjusting device comprises worm and worm wheel, described worm gear is connected with the overcoat of described damper, described worm gear and described worm meshing, described worm screw is rotated by the described overcoat of described worm gear drives and rotates, and the rotation of described overcoat changes the moment of torsion of described torque spring.

The draw-in groove for user's rotary worm is carved with on described worm screw top.

The described outer scale that is carved with sign worm screw rotation angle that puts.

There is positioning hole at described worm gear center, and described overcoat is affixed by the pin and the described worm gear that cooperate with described worm gear positioning hole.

The beneficial effects of the utility model are: with the screw-driver worm screw that turns clockwise, promote worm gear along worm shaft to rotation, drive the torque spring radial contraction, moment of torsion is increased progressively.Observe the overcoat scale value simultaneously, directly cause and reach till the ideal value, this moment, worm screw automatically locked worm gear, adjusted angle of revolution, speed, moment of torsion thereby reach, until the requirement that reaches ideal value.

Embodiment

In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As shown in Figure 1, fitting seat 3, end cap 4, screw 9, worm screw 1, worm gear 2 combine and assemble become an adjusting device.Assembling form: after worm gear 2 and worm screw 1 engagement, the draw-in groove of worm screw 1 is aimed at fitting seat card muscle, and free state is put into fitting seat, and screw 9 is fixed in end cap 4 on the fitting seat, forms a closed shell, the small and exquisite exquisiteness of profile.Damper comprises cover 6, overcoat 5, torque spring 7, " O " RunddichtringO 8 and damping silicone grease in the damping.In cover 6 and overcoat 5 bottoms be band draw-in groove semi-round ball, favourable torque spring 7 assemblings limit torque spring 7 simultaneously and do invalid rotation because of inefficacy, the end centration axis be two keys " in " font, in order to the moment of torsion of transmission torque spring 7, and easy to assembly, stress balance.Overcoat 5 axle heads and worm gear 2 centers " in " the font hole becomes transition fit to be connected, when the user utilizes screw-driver or other instruments draw-in groove by worm screw 1 top that worm screw is rotated, worm screw drives the worm gear rotation, the rotation of worm gear drives overcoat 5 and rotates, one end of the torque spring 7 that is connected with overcoat 5 rotates thereupon, thereby changed the operating angle of torque spring 7 these ends, changed the moment of torsion of torque spring 7, made torque spring 7 lay in certain energy in advance.The angle difference that worm screw 1 is rotated, the energy difference of deposit in advance of torque spring, when adjustable damper is connected with driven device (as light-duty electrical equipment lid, small-sizedly cashier's office in a shop renovate, the upright light-duty cabinet door etc. of adorning), moment of torsion when the energy that torque spring 7 is laid in advance will influence adjustable damper release, thus release rate influenced, reach the purpose of adjustment.The intermediate section of interior cover 6 is " ten " font oil storage tank, and to store quantitative damping silicone grease, two column part has seal groove, loads onto " O " RunddichtringO and prevents damping silicone grease internal and outernal leakage.Be with ten evenly divided values outward, reference during for adjusting, the torque spring design is adopted and is guaranteed that pitch has certain interval, produces lethality because of length change when preventing to regulate.

The schematic representation one of the adjustable damper that the utility model provides and figure two are respectively as shown in Figures 2 and 3.

The main sectional view of the adjustable damper that the utility model provides and right elevation are respectively as shown in Figure 4 and Figure 5.

The adjustable damper that the utility model provides mainly is applicable to the slow rotating machinery of small-sized upturning lid, as light-duty electrical equipment lid, as shown in Figure 6, small-sizedly cashier's office in a shop renovates, the upright light-duty cabinet door, alternative hinge commonly used and hinge adorned.Major advantage is to realize slow opening or Slow Close, and noiseless has solved the hidden danger and the quality problems that cause because of reversal rate is too fast.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
