Abstract
The utility model relates to a hydraulic damper capable of realizing different heterodromous rotation speeds through arranging one-way damping block. The hydraulic damper consists of an outer shell (3) and a shaft core (5) arranged in the center of the outer shell (3). At least one shaft wing (K) with a damping hole at the end part is arranged at the side part of the shaft core (5). The hydraulic damper is characterized in that a one-way adjusting device (H) formed by a one-way damping block (7) and a spring (8) is arranged on the shaft wing (K), the one-way adjusting device (H) is arranged in a sliding groove (4) arranged on the shaft wing (K), and the end of the one-way damping block (7) far away from the spring (8) is tilted. The hydraulic damper is particularly suitable for the rotating shafts of turnover covers arranged on pianos, toilet bowls, exquisite toy boxes, car rear case covers and the like and is used for realizing that the turnover covers can be manually, upward and rapidly opened and can be downward and slowly closed by virtue of the gravity per se.
Description
Technical field:
The present invention relates to rotate and reverse the hydraulic element technology that damping does not wait.
Background technique:
At present, in the hydraulic unit of many products, for example: the hydraulic damping element has been used at the rotating shaft position of piano lid, and its deficiency is: the forward rotation speed and the backward rotation speed of the rotating shaft of piano lid are equal to, this be since during its forward and reverse rotation suffered hydraulic damping be equal to.
If, the speed speed closed with it that allows the above-mentioned piano lid that is supported by hydraulic unit open is incoordinate, for example: the speed of staff pull-up piano lid is very fast, make the speed of piano lid auto-closing very slow, in the use just very smoothly, therefore, this problem, needs when the speed speed closed with it that promptly allows the piano lid that supported by hydraulic unit open should be used according to people are incoordinate problems, are that people manage the desire solution always.
Summary of the invention:
The present invention's purpose:
Propose a kind of by the hydraulic damper that unidirectional damping block realizes that incorgruous rotating speed is different is set.
In order to realize the object of the invention, intend to adopt following technology: the present invention is made of a shell and the axle core that is positioned at the center of shell, and, sidepiece at this core is provided with at least one is provided with damping hole in the end the axle wing, it is characterized in that: on the above-mentioned axle wing, be provided with and withstand unidirectional damping block and affixed with it by a unidirectional damping block and an end, the unidirectional controlling device that the affixed spring in the other end and chute bottom constitutes, and, this unidirectional controlling device is to be positioned to be arranged on above-mentioned chute on the wing, and this unidirectional damping block tilts away from an end of spring.
The present invention's characteristics compared with the prior art: owing to be provided with by an end on the axle wing of the present invention is the unidirectional damping block of inclination and the unidirectional controlling device that spring constitutes, just make mechanism of the present invention form and rotate and reverse the hydraulic element that damping does not wait, be and form the mechanical device that positive rotary speed and speed reversal do not wait and created condition.
Description of drawings:
Figure has illustrated the embodiment of a kind of single shaft airfoil structure of the present invention.
1. damping hole; 2. sap cavity; 3. shell; 4. chute; The axle core; 6. damp liquid (for example: machine oil); 7. unidirectional damping block; 8. spring; H. unidirectional controlling device; K. the axle wing.
Embodiment:
As shown in the figure, when the present invention was static, under the effect of spring 8 elastic force pressures (for example: its elastic force pressure is designed to 0.5 newton), the inclination position (towards the left side) of unidirectional damping block 7 is suppressed stretched out in damping hole 1.
When the present invention clockwise rotates, damp liquid 6 in the sap cavity 2 by sap cavity 2 right sides by damping hole 1 and the overhead stream of crossing unidirectional damping block 7 to sap cavity 2 left sides, at this moment, because unidirectional damping block 7 also participates in having formed the resistance to damp liquid 6 in damping hole 1, force the flow section of damping hole 1 to be reduced, therefore, the flow resistance of this moment has been strengthened, and causes rotating speed of the present invention very slow.
When the present invention rotates counterclockwise, damp liquid 6 in the sap cavity 2 passes on left damping hole 1 by sap cavity 2 and flows to sap cavity 2 right sides, when damp liquid 6 passes through the upper inclined surface (for example: 45 degree can be got in this inclined-plane) of unidirectional damping blocks 7, radial pressure to this unidirectional damping block 7 forms, as long as (for example: this elastic force pressure is very little to overcome the elastic force pressure of spring 8, be designed to 0.5 newton), just can force unidirectional damping block 7 axial displacements like a cork, removed the flow resistance that this unidirectional damping block 7 formed damp liquid 6 originally, damping hole 1 becomes big, flow resistance reduces, and the flow velocity of damp liquid 6 increases, and rotating speed of the present invention increases.
