Description
Technical field
The utility model relates to a kind of pivot device that is used in electronic product, refers to that especially a kind of pivot, banking stop, support and stationary cam of relying on forms multiple block effect, and is used for increasing the multiple limit configuration of the pivot device of support force.
Background technique
The screen of people's common electronics product is provided with at least one pivot device with between body, and screen and body are relatively rotated, use or folding storage so that open, the general relative each other cam set of pivot device utilization, and the mutual collocation of elastic element, and rotate required torsion and support force, and in the rotation process, normally rely on pivot and link the all-in-one-piece banking stop,, and reach the effect that limits rotation angle with the mutual clip of the stop block on the support.
As shown in Figure 1, aforementioned pivot device 10 mainly comprises following member: a pivot 11, a banking stop 12, a support 13, a stationary cam 14, a turn cam 15, an elastic element 16 and a fixed block 17, banking stop 12, support 13, stationary cam 14, turn cam 15 and elastic element 16, be to be set in regular turn on the pivot 11, pivot 11 is terminal and screw togather and finish assembling with fixed block 17.Wherein, after pivot device 10 is opened into set angle, be to rely on the set arc stopper part 121 of banking stop 12 outer periphery, and support 13 and banking stop 12 closings mutually the stop block 131 of corresponding setting, the block strength of mutual block is as the purpose that supports angle between screen and body.
Yet general pivot device is to use one or more banking stop 12, increases the means of block effect during as rotation; But in fact, because banking stop 12 is very limited with 131 block power that can produce of stop block of support 13, and block power is to concentrate on stopper part 121 and the stop block 131, will cause the stopper part 121 of banking stop 12, or the damage of the stop block 131 of support 13, especially banking stop 12 is to be arranged on the pivot 11, and a plurality of banking stops 12 is set to increase the mode of block power, block strength is to apply in the same way shearing stress on pivot 11, causes the wearing and tearing or the fracture of the outer wall of pivot 11 easily.
So, for solving the disappearance that above-mentioned pivot device 10 is using, the ad hoc meter of the utility model designer utilizes a plurality of members to produce multiple block effect, so that block strength is dispersed on each member, unlikely in order to increase block strength, and cause the damage of pivot device member, and take into account the normal use of pivot device.
