Abstract

The utility model relates to a rotation hinge in a movable screen, which is applied when rotating and lifting. The utility model has a relative rotation fixed stand and a rotation stand; the upper part of the fixed stand is connected to a fairlead; wherein the fairlead is provided with two or more outer position grooves and two or more corresponding staggered inner positioning grooves and limit films; wherein the limit films touches and are guided by the rotation stand; the inner fixed flanges and outer fixed flanges are correspondingly positioned in the place where the inner grooves and the outer grooves locate. By the position grooves and the fixed flanges, the rotation stand relative rise, thus maintaining stable four contacts to prevent sloshing; when the rotation stand transfers to a preset position, the positioning grooves and fixed flanges is mutually anastomosed, thus the rotation stand generates a downward movement to increase hand feeling in position and stability after position of front and back screens.

Description

Rotary hinge with lifting structure

Technical field

The utility model relates to a kind of rotary hinge with lifting structure, and particularly a kind of being applicable to can make screen rise when beginning to rotate on the rotary hinge, and descending during to the location produces the device of location hand feeling.

Background technique

Notebook computer, PDA Personal Digital Assistant (Personal Digital Assistant; PDA), 3C electronic equipments such as digital camera and mobile phone, mainly be to adopt hinge (Hinge) to be coupling the mode winding display device and main frame body, in use, as long as can use after will display device launching; If when not using, display device and the doubling of main frame body can be folded, to reduce volume, be convenient to collect and carry.

Therefore existing rotary hinge does not have the structure of screen rise and fall, when screen rotate when if insufficient height or screen are crooked, is very easy to the keyboard that rubs, so screen height must be improved, and makes degraded appearance or inharmonious.

Disclosed a kind of rotational structure No. 495130 at the TaiWan, China patent announcement, make display device main frame body and rotating relatively, and display device presented to the user who is positioned at different amount, above-mentioned rotational structure comprises swivel base, form first cylindrical body, and the first cylindrical body outer rim both sides respectively comprise a groove, and two grooves are relative; Pivot is articulated on the connection side and swivel base of this display device; Fixed base be fixed on the main frame body, and fixed base forms second cylindrical body, and second cylindrical body comprises through hole and two slots, and through hole is formed at the second cylindrical central position, and through hole holds swivel base just, and slot also is formed on the through hole, and two slots are relative; And two resilient members that is contained in the slot, comprise flange on the resilient member; Groove then is located in the flange when turning to the fixed position by swivel base in fixed base, and produces the effect of location.

Yet the flange of above-mentioned rotational structure and the design of the correspondence of groove are not good, and the effect that causes flange to be sticked in groove is affected, thereby the effect of the feel of location that produces and location is limited; In addition, this device does not obviously have the function of the rotating distance of restriction display device, because being connected to the signaling line of main frame body, display device can't be subjected to excessive distortion, therefore display device must be less than 360 degree with respect to the rotating distance of main frame body, because above-mentioned rotational structure is not restricted on rotating distance, therefore occur the signaling line excessive distortion most probably and be entangled with, even the facts that causes electronic equipment to damage takes place.

The model utility content

Main purpose of the present utility model is to solve above-mentioned problems of the prior art, a kind of rotary hinge with lifting structure is provided, be specially adapted to the display device of electronic equipment, except making the display device can be relatively its main frame body rotation, and can be in rotary course, the relative main frame body of interlock screen lifting action, to avoid its conflict keyboard, display device is just configurable in the lower height position thus, dwindles the electronic equipment overall volume, and has appearance preferable, that coordinate.

Another purpose of the present utility model has location hand feeling when being to make display device to rotate to desired location, and the advantage that makes display device have being difficult for rocking, and significantly promotes its stability.

For achieving the above object, in the preferred embodiment of the present utility model, having can counterrotating fixed base and rotary support, this fixed base upper end is connected with fairlead, this fairlead has perforation for threading, and be provided with plural outside fix groove and corresponding in positioning groove, the angle of required location when these positioning grooves rotate according to hinge and setting, as set 0 degree and spend with 180, then there are two outside fix grooves, 180 degree of being separated by to be located at this fairlead outer rim circumference in equal parts position, there are two interior positioning grooves to be located at this perforation inner circumference edge circumference in equal parts position in addition, quantity and angle are corresponding with the outside fix groove and stagger, this rotary support lower end then is provided with this fairlead of butt and is subjected to the banking stop of rotary support interlock, in on the corresponding fairlead of this banking stop, the outside fix groove location is provided with the one group of internal fixation flange and the outer fixing flange of mutual coupling; Rotary support and fixed base rise this position rotating support position by positioning groove and holding flange when rotated, and after the rotary support rising, because of holding flange more than 4 being arranged respectively on the fairlead internal and external circumference, make rise back and this fixed base of rotary support can keep contact preventing and rock at stable 4, after rotary support goes to desired location, the identical mutually rotary support of positioning groove and holding flange can produce the decline location action, feel in the time of can promoting the screen front and back side location and the stability behind the location.

In sum, the rotary hinge with lifting structure of the present utility model can dwindle the electronic equipment overall volume, and feel can promote screen front and the back side location time and the stability behind the location.
