Abstract
The utility model discloses a rotary shaft capable of realizing gentle opening and heavy closing, which comprises a rotary shaft and a holder. A retainer plate, a support, a plurality of disc spring plates and a nut are sequentially sleeved onto the rotary shaft, one end of the rotary is connected with the holder fixedly, the other end of the rotary shaft is fastened via the nut, and a gear plate is sleeved on the rotary shaft and between the support and the disc spring plates. Advanced falling of a screen due to weight of the screen during closing can be prevented by the aid of the additional gear plate and the additional clamp post, thereby convenience in operation of a notebook computer is enhanced, and quality and performance of the notebook computer are improved.
Description
Technical field
The utility model relates to a kind of rotating shaft, particularly is widely used in can connect two parts and make its a kind of rotating shaft of easy opening and heavy closing in relative rotation.
Background technique
Because of rotating shaft torsion needs can be at the arbitrarily angled screen that props up, and after through at least 20000 life tests, has said function, so digital products such as existing notebook must be taken into account torsion decline situation when torsion setting, and can add a safety factor, make that rotating shaft torsion can be bigger; So all bigger and switch basically identicals of digital product used strength when opening and close such as existing notebook, this can have influence on user's feel, and need up to raise screen on the other hand when opening, the another hand must be pinned base does not make it upwarp, operation inconvenience.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of rotating shaft of easy opening and heavy closing, overcomes the inconvenience that rotating shaft is operated when opening, and the function of closing is opened and closed to the realization product easily.
The utility model for the technological scheme that solves its technical problem and adopt is: a kind of rotating shaft of easy opening and heavy closing, comprise rotating shaft and fixing frame, in rotating shaft, comprise and be with stop tab successively, bolster, several dish type shell fragment and nuts, described rotating shaft one end is fixedlyed connected with fixing frame, its the other end is fastening by nut, between bolster and dish type shell fragment, be arranged with a gear sheet in the described rotating shaft, described gear sheet and rotating shaft can relatively rotate, the peripheral gear teeth of described gear sheet are unified oblique setting, the described gear teeth one side is a sliding surface, opposite side is the face of pushing against, also be provided with an elastomer, an elastomeric end is fixed positioned on the bolster, and elastomeric the other end elasticity pushes against on the gear teeth in the gear sheet, promptly similar click, when the gear sheet rotates, the elastomeric the other end can slip over the sliding surface of the gear teeth in the gear sheet, and when the gear sheet did not rotate, the elastomeric the other end can push against the face that pushes against of the gear teeth in the gear sheet.Rotating shaft is in opening procedure, frictional force between gear sheet and the adjacent components is greater than the frictional force between elastomer and the gear sheet upglide surface, the elastomer the other end slips over the sliding surface on the gear sheet, the stationary positioned effect does not take place in gear sheet and elastomer, can easily rotating shaft be opened, after opening, the elastomer the other end withstands and pushes against the face location, the gear sheet can't rotate, thereby can prevent that (referring to that product screen and base are acute angle) causes unexpected closed because of the screen weight issue after opening; In the rotating shaft closing course, the gear teeth that this moment, the elastomer the other end pushed against on the gear sheet push against the face side, the gear sheet is withstood the location by the elastomer the other end, press down screen, the gear sheet begins and the adjacent component friction that rotates, and frictional force rotates, and the elastomer the other end pushes against the face that pushes against power on the gear sheet greater than described rotation friction, rotating shaft rotation and the gear sheet does not rotate this moment, screen are slowly closed, can prevent to cause falling in advance because of the screen weight issue in closing course.
As further improvement of the utility model, in rotating shaft, be positioned at the bolster side and also be with first cam and second cam successively, and first cam is fixed positioned on the bolster, one cam is provided with locating column, corresponding bolster is provided with the positioning hole with the locating column coupling, by locating column being inserted positioning hole first cam orientation is fixed on the bolster, make win cam and bolster follow the rotation of rotating shaft and rotate, second cam is movably set in the rotating shaft, be that both can relatively rotate, rotation by first cam makes second cam be implemented in freely endwisely slipping in the rotating shaft, by in the rotating shaft first, two cams relatively rotate realizes the fastening common technology for those skilled in the art between the part in the rotating shaft, so no longer describe in detail.
As further improvement of the utility model, described elastomer is the L type, can be other shapes too, is a kind of backstop.
As further improvement of the utility model, be provided with the noise reduction pad between second cam and the gear sheet in the described rotating shaft, the pad of the enough common increase rubbing surfaces of energy substitutes equally.
As further improvement of the utility model, between the described bolster and first cam, be equipped with pad between gear sheet and the dish type shell fragment and between nut and the dish type shell fragment.
The beneficial effects of the utility model are: this rotating shaft is by increasing a gear sheet and card post newly, because of the card post is an elastic element, when the gear sheet turns round, can be pushed and block open gear by gear: when product when opening, the gear sheet with the card post do not act on, can easily product be opened; When closure, the gear sheet is blocked post to be blocked, and beginning and adjacent pads friction produce torsion, prevents from when closure to have improved the operational convenience of notebook, and to have taken into account the quality parameter of product itself because of the screen weight issue causes falling in advance.
