Description

Pivot device

Technical field

The utility model relates to a kind of pivot, relates in particular to a kind of pivot that is arranged on electronic equipment, and can prolong the working life of pivot device and increase the fixing fastening force, and the overall volume that can effectively dwindle pivot device.

Background technique

Along with Information technology and development of computer progress, have suitable many of the electronic equipment of screen and body, as digital projection camera, liquid crystal display, notebook or palm CD-ROM drive etc.This class of electronic devices is for making in operation and using more convenient; regular meeting is provided with pivot device between its screen and body; this screen can be rotated with respect to body; therefore how to provide pivot structure intensity higher between screen and body, become the important topic of those skilled in the art's research.

The structure of known pivot device as shown in Figures 1 and 2, this pivot device mainly includes fixed base 50a (60a), pintle assembly 51a (61a) and a plurality of elastomer 52a (62a).The end of pintle assembly 51a penetrates fixed base 50a, each elastomer 52a and pad in proper order, utilizes the fixed by nut packing again.Wherein, the assembling mode of each elastomer 52a (62a) is two groups (as shown in Figure 1) or one group (as shown in Figure 2) reverse stacked combination.Elastomer 52a clamping makes fixed base 50a can produce the elastic clip effect of pulling when rotated between fixed base 50a and nut.

Yet, because each elastomer 52a of above-mentioned known pivot device is for oppositely piling up assembling, the area of contact of each elastomer 52a is only in the narrow and small zone of outer periphery, in the process that nut inwardly screws in, its fastening force that can produce is quite little, and need significantly increase the displacement amount of nut, more because displacement amount strengthens, often surpass the elastic limit of this elastomer 52a respectively and make elastomer 52a produce plastic deformation, and significantly shortened the working life of pivot device.In addition, elastomer 52a directly is bent upwards shaping from the aperture, will make this aperture produce irregular change in shape, and causes the defect rate of product to improve; Moreover each elastomer 52a can't shorten the total length of this pivot device for oppositely piling up assembling, deviates from mutually with the requirement of information products " light, thin, short, little ".

So, the design people is in view of the defective that exists in the above-mentioned prior art, rely on the sector experience for many years of being engaged in, at carrying out improved defective, through concentrating on studies and cooperating actual utilization, in line with excelsior spirit, propose a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.

Content of the present utility model

Main purpose of the present utility model is a kind of pivot can be provided, it utilizes respectively, and this elastomer piles up setting in the same way and has high structural strength, making respectively, this elastomer is difficult for producing plastic deformation, thereby prolonged the working life of pivot device, and increased the fixing fastening force, can effectively dwindle the overall volume of pivot device.

To achieve these goals, the utility model provides a kind of pivot, and this pivot includes fixed base, pintle assembly and a plurality of elastomer.Wherein, this fixed base has through hole, and this through hole wears connection for pintle assembly; This pintle assembly has pivot and is connected the locked assembly of this pivot; Between this locked assembly and fixed base, be provided with a plurality of elastomers; This elastomer has base plate and reaches around the extension board that is arranged on this base plate periphery; Respectively this elastomer is for piling up setting in the same way, thereby realizes above-mentioned purpose.

Embodiment

Relevant feature of the present utility model and technology contents see also following detailed description and accompanying drawing, and accompanying drawing only provides reference and explanation, is not to be used for the utility model is limited.

Fig. 3 is a pintle assembly three-dimensional exploded view of the present utility model, and Fig. 4 is the assembled sectional view of the utility model first embodiment's pivot.The utility model provides a kind of pivot, and as shown in the figure, pivot device 1 mainly includes fixed base 10, pintle assembly 20 and a plurality of elastomer 30, wherein:

Fixed base 10 can be the direct impact briquetting of metal sheet, and is nearly " L " shape.Below the one plate, locate to have through hole 11, on another plate, then offer a plurality of circular holes 12 of wearing for fixedly connected assembly such as screw of being used for, be provided with two positive stops 13 at the outer periphery place of through hole 11, produce position-limiting action with rotating range to fixed base 10.

The locked assembly 22 that pintle assembly 20 includes pivot 21 and is connected with pivot 21.One end of pivot 21 is extended with fixing part 211, offers two holes 212 on fixing part 211, then is extended with joint 213 at the other end of pivot 21; Joint 213 is used for penetrating the through hole 11 of fixed base 10.Locked assembly 22 can be nut, bolt or other connection part, and present embodiment is a nut.In addition, when locked assembly 22 was bolt, 213 of the joints of pivot 21 formed screw, also have effect same as the previously described embodiments.In addition, pintle assembly 20 further can include limiting board 23, first pad 24 and second pad 25.Be provided with oblong slotted eye 231 in the center of limiting board 23, be provided with position-limit foot 232 in the outer periphery of limiting board 23, the positive stop 13 corresponding settings of position-limit foot 232 and fixed base 10 are to produce the effect of mutual stopper location.

Elastomer 30 is arranged on the joint 213 of pivot 21, and between locked assembly 22 and fixed base 10.In like manner, also elastomer 30 can be arranged on (not shown) between the left side of pivot 21 and the fixed base 10, also have equal effect.Elastomer 30 has circular bottom plate 31 and around the extension board 32 that is arranged on base plate 31 peripheries, extension board 32 can be diagonally extending, makes elastomer 30 be dish-shaped shape.Be provided with the perforation 311 that wears connection for the joint 213 of pivot 21 in the center of base plate 31; Each elastomer 30 is for piling up setting in the same way, and is formed with clearance space A at two 30 adjacent on elastomers.
