Abstract
A slipping gear structure applied to a CD (compact disc) driver serves as a transmission part connected between a driving gear and a driven gear and comprises a first gear and a second gear which are arranged on the same centre shaft, a torsion spring is sleeved on the centre shaft, and two ends of the torsion spring are respectively clamped on the first gear and the second gear. The slipping gear structure has a simple structure; when the relative rotation is developed between the first gear and the second gear, the impact on the gears by other components is softened by the buffering action of the torsion spring, the damage to the internal components is avoided when the CD player is subjected to the impact, the adaptability of the CD player to the environment is improved, the anti-impact ability is enhanced, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of CD drive inner structure, specifically can realize the gear structure that skids that cushions.
Background technology
Adopt in the CD drive gear-driven parts a lot, the stable locking mechanism of each component locations when being used for guaranteeing not have dish.This mechanism avoid because these parts in quick condition and the position uncertain bring go into the dish problem.CD drive owing to be subjected to extraneous impact internal part also can produce impact each other, causes part distortion to lose efficacy if this impact is dealt with improperly when idle and use easily.
The utility model content
The technical problems to be solved in the utility model provides a kind of gear structure that skids that is applied to CD drive that impacts between the CD drive inner part that slows down.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of gear structure that skids that is applied to CD drive, be connected between driving gear and the follower gear as drive disk assembly, comprise first gear, second gear that are arranged on the same axis, be with the button spring on axis, button spring two ends are stuck in respectively on first gear, second gear.
As improvement to such scheme, be provided with bayonet socket at first gear, second inner ring gear, button spring both ends are stuck in the bayonet socket respectively.
As further improvement, second gear and axis are structure as a whole.
The utility model is simple for structure, when relatively rotating between first gear and second gear, slowed down the impact of miscellaneous part by the buffering of button spring to gear, avoid Disc player internal part when being subjected to impacting to damage, improve the adaptive capacity to environment of Disc player, increased Disc player impact resistance and serviceable life.
Figure of description
Embodiment
For the ease of those skilled in the art will recognize that the utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
Shown in accompanying drawing 1,2, the gear structure that skids that present embodiment disclosed is mainly used in the Disc player, and inner each parts relative motion causes parts damages when preventing that Disc player is subjected to impacting, and increases the impact resistance of Disc player.
This gear structure that skids comprises that first gear 2, second gear 3 and button spring 4, the first gears 2 are provided with axis 1, the second gear 3 and are placed on the axis.Simultaneously, also be with a button spring 4 on axis 1, button spring 4 is between first gear 2, second gear 3.The two ends of button spring 4 are stuck in respectively on first gear 2, second gear 3, are provided with bayonet socket 21,31 at first gear 2, second gear, 3 inner rings, and the two ends of button spring 4 are stuck in respectively in the bayonet socket 21,31.
When the impact that is subjected to external force when first gear 2 or second gear 3 rotates suddenly,, slowed down the transmission of this impact, reached the purpose of guard block by the buffering of button spring 4.
Again as shown in Figure 3, be applied to synoptic diagram on the Disc player for present embodiment.Wherein, a worm screw 5 engagements in first gear 2 and the Disc player, second gear 3 and a tooth bar 6 engagements, when Disc player is subjected to external impacts, the impulsive force that tooth bar 6 produces is delivered to the buffering that second gear 3 passes through button spring 4 afterwards, both prevented the part deformation that the impact between the tooth bar 6 and second gear 3 causes, and also can prevent the shock-produced deformation between first gear 2 and the worm screw 5, part of damage when having avoided Disc player to be subjected to impacting effectively.
The foregoing description is the preferable implementation of the utility model; in addition; the utility model can also have other implementations, need to prove, any conspicuous replacement is all within the utility model protection domain under the prerequisite that does not break away from the utility model design.
