Abstract
The invention discloses a hydraulic damper for realizing different heterodromous speeds by arranging a unidirectional damping block, which consists of a shell (3) and a shaft core (5) positioned in the center of the shell (3). In addition, the lateral of the shaft core (5) is provided with at least one shaft wing (K) of which the end part is provided with a damping hole (1). The hydraulic damper is characterized in that: the shaft wing (K) is provided with a unidirectional adjustment device (H) consisting of the unidirectional damping block (7) and a spring (8); moreover, the unidirectional adjustment device (H) is positioned in a chute (4) on the shaft wing (K); in addition, one end of the unidirectional damping block (7) far from the spring (8) is inclined. The hydraulic damper is particularly suitable to be arranged on rotating shafts of flaps of pianos, flush toilets, delicate toy boxes, automotive rear case covers and the like so as to make the flaps quickly opened upwards manually and slowly closed downwards by means of self gravity.
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 lets 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 lets 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 through 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; Technology below intend adopting: the present invention is made up of a shell and the axle core that is positioned at the center of shell, and, be provided with at least one is provided with damping hole in the end the axle wing at the sidepiece of this core; 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 and existing technology characteristics relatively: 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:
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 through 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 rotated counterclockwise, the damp liquids 6 in the sap cavity 2 passed on left damping hole 1 by sap cavity 2 and flow 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 overcome the elastic force pressure (for example: this elastic force pressure is very little, is designed to 0.5 newton) of spring 8; 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, and flow resistance reduces; The flow velocity of damp liquid 6 increases, and rotating speed of the present invention increases.
