Abstract
The invention discloses a damping structure of a shaft, belonging to the technical field of machinery, in particular relating to a damping structure for an automatic opening of a rotary shaft. The dumping structure provided by the invention comprises a fixed shaft and a rotary shaft capable of rotating automatically for a certain angle, and is characterized in that one end of the fixed shaft is sleeved outside one end of the rotary shaft; a clearance is reserved between the,matched surfaces of the fixed shaft and the rotary shaft; one end of the fixed shaft is provided with a curved concave wheel; the curved concave wheel is sleeved on the rotary shaft, and is matched with the rotary shaft through a ledge; and damping oil is poured into an enclosed cavity which is formed by the ledge and the clearance. According to the damping structure for the automatic opening of the rotary shaft, the clearance is reserved between the fixed shaft and the rotary shaft, and the damping oil is poured into the clearance, thus the force of impact of the automatic starting of the rotary shaft can be buffered effectively, the products are opened to the required maximum angle slowly, and the injection rate of the damping oil can be adjusted according to required damping force so as to achieve the expected damping effect, so that the force of impact is prevented from being over great when the products are opened and causing damage to other architectures.
Description
Technical field
The present invention relates to a kind of damping structure of axle, belong to field of mechanical technique.
Background technique
Use the structure of automatic opening rotating shafts for some, rely on to overcome transition point once less initial external force and can realize that rotating shaft is opened into required maximum angle automatically, this structure has lot of advantages, has been employed on many products such as notebook computer.But automatic opening rotating shaft is in the process that automatically is opened into maximum angle, because mechanical motion inertia can produce certain impact force to product, this impact force is very disadvantageous to product.
Summary of the invention
Technical problem to be solved by this invention provides a kind of damping structure for automatic opening of rotary shaft, plays certain buffer function, makes the rotating shaft on the product slowly be opened into required maximum angle.
For solving the problems of the technologies described above, the invention provides a kind of damping structure for automatic opening of rotary shaft, but comprise the rotating shaft of a stationary axle, an automatic rotation several angle, it is characterized in that an end of described stationary axle is placed in outside described rotating shaft one end, preset clearance between its fitting surface, described stationary axle one end is provided with that a curved surface is recessed takes turns, the recessed wheel of described curved surface is placed in the described rotating shaft, matches by shoulder with described rotating shaft, injects damping oil in the enclosed cavity that described shoulder and described gap consist of.Be provided with shoulder and can prevent that rotating shaft from rocking and oil leakage phenomenon, can damping force as required adjust the injection amount of damping oil, reach the damping of expection, impact force is excessive when avoiding opening product, and causes other frameworks to damage.
The recessed end end face of taking turns of described curved surface comprises concave curved surface.
Cover has a curved surface cam in the described rotating shaft, and an end end face of described curved surface cam comprises convex surface, matches with the recessed concave curved surface of taking turns of described curved surface.
The described curved surface cam the other end is connected with spring one end.
The described rotating shaft the other end is provided with opening handle, and described opening handle and described rotating shaft are hinged.
The described spring the other end and described opening handle offset.
The beneficial effect that the present invention reaches: damping structure for automatic opening of rotary shaft of the present invention preset clearance and inject damping oil in stationary axle and rotating shaft, can effectively cushion the impact force of the automatic unlatching of rotating shaft, product is opened into required maximum angle slowly, and the injection amount of can damping force as required adjusting damping oil, reach the damping of expection, impact force is excessive when avoiding opening product, and causes other frameworks to damage.
Description of drawings
Fig. 1 is damping structure for automatic opening of rotary shaft schematic representation of the present invention;
Fig. 2 is the A section sectional view of Fig. 1.
Wherein, 1, stationary axle; 2, rotating shaft; 3, curved surface is recessed takes turns; 4, gap; 5, shoulder; 6, curved surface cam; 7, spring; 8, opening handle.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.Following examples only are used for technological scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
As shown in Figure 1 and Figure 2, but damping structure for automatic opening of rotary shaft of the present invention comprises the rotating shaft 2 of stationary axle 1, an automatic rotation several angle, rotate each other with stationary axle 1, curved surface is recessed takes turns 3, one end of stationary axle 1 is placed in outside rotating shaft 2 one ends, preset clearance 4 between its fitting surface, so that the injection damping oil, oil mass can be adjusted by the damping dynamics.In order to prevent that rotating shaft 2 from rocking and oil leakage phenomenon occurs, at recessed 3 the fitting surface of taking turns of rotating shaft 2 and curved surface shoulder 5 is set.
Cover has a curved surface cam 6 in the rotating shaft 2, and an end end face of curved surface cam comprises convex surface, matches with recessed 3 the concave curved surface of taking turns of curved surface.Curved surface cam 6 the other ends are connected with spring 7 one ends.Rotating shaft 2 the other ends are provided with opening handle 8, and opening handle 8 is hinged with rotating shaft 2.Spring 7 the other ends and opening handle 8 offset.
When automatic opening rotating shaft in the process that automatically is opened into maximum angle, the end that rotating shaft 2 is enclosed in the stationary axle 1 moves vertically, because having injected damping oil in the gap between its fitting surface, therefore make the axial motion of rotating shaft more slow, can make the slowly desirable maximum angle of bullet of product.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
Claims (2)
1. damping structure for automatic opening of rotary shaft, but comprise the rotating shaft of a stationary axle, an automatic rotation several angle, it is characterized in that, one end of described stationary axle is placed in outside described rotating shaft one end, preset clearance between its fitting surface, described stationary axle one end are provided with that a curved surface is recessed takes turns, and recessed wheel of described curved surface is placed in the described rotating shaft, match by shoulder with described rotating shaft, inject damping oil in the enclosed cavity that described shoulder and described gap consist of;
