Description
Technical field
The utility model relates to a kind of rotating shaft, relates in particular to a kind of novel rotating shaft that is used on the electronic products such as TV, computer monitor.
Background technique
Rotating shaft is one of main accessory common on TV, the computer monitor, and it can make everybody when using display device, can adjust the display device angle, to obtain better visual effect.Existing turning shaft structure is as shown in Figure 1; Comprise movable frame 1 ' and fixing frame 2 ', movable frame 1 ' is rotatably connected through coupling shaft 3 ' with fixing frame 2 ', and between movable frame 1 ' and fixing frame 2 ', is provided with POM plate 4 '; Be provided with rotary spacing groove 11 ' at movable frame 1 '; Fixing frame 2 ' is provided with the rotary spacing groove 21 ' corresponding with it, on two rotary spacing grooves, is provided with limited screw 5 ', thereby plays the effect of rotary spacing.Though the rotating shaft of this kind structure makes things convenient for the adjustment of display device angle to a certain extent; But; Because receive rotating shaft intensity, the display device cun not influence of size, rotary spacing groove groove position can not be offered too big, causes the rotation amplitude of rotating shaft little; The visual angle scope that display device can be adjusted is less, has satisfied not the demand that the user adjusts the display device visual angle.In addition, fixing frame is to be processed by ironware, and not only volume is big, and it is bigger to take up room, and weight is heavier, and manufacture cost is higher comparatively speaking.Because receive the influence of turning shaft structure, intensity, this rotating shaft maximum can only be born 37 cun display device, can't satisfy existing larger sized display device and use; And the rotating shaft bulk strength is not enough; In use for some time, occur rotating inflexible phenomenon easily, working life is short.
Summary of the invention
To the problem of above-mentioned existence, the utility model provide a kind of simple in structure, take up room little, in light weight, rotate flexibly, the novel rotating shaft of long service life.
For realizing above-mentioned purpose; The utility model has adopted following technological scheme: a kind of novel rotating shaft, comprise fixing frame and base support, and said fixing frame bottom centre is provided with the hollow spindle that extends vertically; Base support is provided with the axis hole suitable with this hollow spindle; Fixing frame is rotatably connected through this hollow spindle and base support, and the base support bottom wears a machine tooth screw, and this machine tooth screw top is connected with hollow spindle; The bottom edge that fixing frame is corresponding with base support offers the rotary spacing groove, and base support is provided with the spacing block set corresponding with the rotary spacing groove.
Further, be provided with friction plate between said fixing frame and the base support, also be provided with friction pads between friction plate and the base support.
Further, the sheathed pillar cover in said fixing frame and the base support outside, this pillar cover through the machine tooth screw pass one be located at the pillar cover bottom surface retaining washer be fixedly connected with base support, also be provided with a cosmetic sheet on the pillar cover.
Further, also be provided with dull and stereotyped limiting gasket and compression spring between said retaining washer and the machine tooth screw.
Through adopting the aforementioned techniques scheme; The beneficial effect of the utility model is: the utility model is through in material and structural change, replaces original ironware fixing frame with the fixing frame of die cast, and its more original ironware fixing frame on material, density, size, intensity all makes moderate progress; The rotating shaft bulk strength is higher; The maximum display device that can bear 55 cun, and the groove position of the rotary spacing groove of rotating shaft is wideer, makes the rotation amplitude of rotating shaft bigger; Thereby make display device visual angle adjustment range bigger, to satisfy user demand.Owing between fixing frame and base support, be provided with friction plate and friction pads, the rotating shaft rotational stability is better, longer service life.The utility model simple in structure, take up room little, in light weight, rotate flexibly, long service life, and under the prerequisite that cost reduces, have to reach and satisfy its functional requirement.
Description of drawings
Fig. 1 is the structural representation of existing technology shaft;
Fig. 2 is the decomposing schematic representation of the utility model;
Fig. 3 is the composite structure schematic representation of the utility model fixing frame and base support;
Fig. 4 is that this reality is made novel composite structure schematic representation.
Embodiment
Combine accompanying drawing and embodiment that the utility model is further specified at present.
With reference to figure 2, Fig. 3 and Fig. 4, the utility model embodiment discloses a kind of novel rotating shaft, comprises fixing frame 1 and base support 2; Said fixing frame 1 adopts die cast; Fixing frame 1 quality is lighter, and said fixing frame 1 bottom centre is provided with a hollow spindle (not shown) of extending vertically, and base support 2 is provided with the axis hole (not shown) suitable with this hollow spindle; Hollow spindle is inserted in the axis hole, and fixing frame 1 is rotatably connected through this hollow spindle and base support 2.Base support 2 bottoms wear a M8 machine tooth screw 3; These M8 machine tooth screw 3 tops are connected with hollow spindle, make fixing frame 1 and base support 2 rotatable fixed connections, and fixing frame 1 offers rotary spacing groove 11 with base support 2 corresponding bottom edge; Base support 2 is provided with the spacing block set 21 corresponding with rotary spacing groove 11; When fixing frame 1 rotated on underframe support 2, this spacing block set 21 cooperated the effect of playing rotary spacing with rotary spacing groove 11, prevented that the display device rotation is excessive.This rotary spacing groove 11 can increase or dwindle its width according to the needs of display device angular adjustment when producing.
When rotating in order to strengthen rotating shaft flexibly with stable and prevent mutual friction mutually between fixing frame 1 and the base support 2; Between said fixing frame 1 and base support 2, be provided with friction plate 4; This friction plate 4 is provided with 4 spacing salient points 5 with fixing frame 1 corresponding face; Fixing frame 1 bottom be provided with 4 with spacing salient point 5 hole (not shown) one to one; Friction plate 4 injects the corresponding hole internal fixation in fixing frame 1 bottom and the bottom of fixing frame 1 through spacing salient point 5, also is provided with friction pads 6 between friction plate 4 and the base support 2.
Receive the obstruction of extraneous dust or other foreign material for the fixing frame 1 that prevents rotating shaft and the rotary part between the base support 2 and influence the flexibility of its rotation; Said fixing frame 1 and the sheathed pillar cover 7 in base support 2 outsides; This pillar cover 7 through M8 machine tooth screw 3 pass one be located at pillar cover 7 bottom surfaces retaining washer 8 be fixedly connected with base support 2; Also be provided with a cosmetic sheet 71 on the pillar cover 7, this cosmetic sheet 71 plays the effect that a little stops and decorate.Also be provided with dull and stereotyped limiting gasket 9 and compression spring 10 between said retaining washer 8 and the M8 machine tooth screw 3.
The utility model more original ironware fixing frame on material, density, size, intensity all makes moderate progress; The rotating shaft bulk strength is higher; The maximum display device that can bear 55 cun, and the groove position of the rotary spacing groove of rotating shaft can be provided with widelyer according to actual needs, makes the rotation amplitude of rotating shaft bigger; Thereby make display device visual angle adjustment range bigger, to satisfy user demand.The utility model simple in structure, take up room little, in light weight, rotate flexibly, long service life, and under the prerequisite that cost reduces, have to reach and satisfy its functional requirement.
Above embodiment only supplies to explain the usefulness of the utility model; But not to the restriction of the utility model; About the technician in field under spirit that does not break away from the utility model and scope, the various conversion made from change the category that all belongs to the utility model, should limit each claim.
