Abstract
The invention relates to a malposition type cam assembly, which is formed by a first cam and a second cam. A middle through hole is arranged between the first cam and the second cam, a first curved surface and a second curved surface are arranged on the top portion of the first cam, a boss is arranged on the top portion of the second cam, and a third curved surface and a fourth curved surface are arranged on the boss. Compared with the prior art, the matched curved surfaces of the malposition type cam assembly are asymmetrical, equipment such as mobile phones can be turned over in a range from 0 to 360 degrees through matching between the first curved surface and the third curved surface and between the second curved surface and the fourth curved surface of the two malposition cams, requirements of pre-pressure existing when the equipment such as the mobile phones is turned over in the range from 0 to 360 degrees are met, so that the malposition type cam assembly is wide in application scope.
Description
Technical field
The present invention relates to a kind of external equipment and use cam mechanism, especially relate to a kind of dislocation type cam pack.
Background technique
Existing external equipment generally is made up of two cams with cam mechanism; What these two cams adopted is symplex structure; Promptly mate in curved surface on cam and the cross section on another cam, when therefore such cam structure being applied to mobile device, in clamshell phone; The angle of opening of mobile phone all is to reach 180 degree or bigger angles, thereby has caused the inconvenience of using.
Summary of the invention
The object of the invention is exactly to provide a kind of 0～360 degree of can realizing to open the dislocation type cam pack that Applicable scope is wider for the defective that overcomes above-mentioned existing technology existence.
The object of the invention can be realized through following technological scheme:
A kind of dislocation type cam pack; This cam pack is made up of first cam and second cam; In the middle of first cam and second cam center through hole is set, it is characterized in that the top of described first cam is provided with the first surface and second curved surface; The top of described second cam is provided with a boss, and the 3rd curved surface and the 4th curved surface are set on this boss.
Described first cam is the concave shape structure, and this first flank of cam is a convex structure for four jiaos, is plane structure all around.
Described first surface has two, and the both sides of this first surface are the slope shape structure, is located at the outside of the first cam top depression shape structure.
Described second curved surface has two, is the crescent shape structure, is located at the inboard of first surface.
Described second cam is the convex shape structure, and this second flank of cam is a convex structure for four jiaos, is plane structure all around.
Described the 3rd curved surface is the crescent shape structure, is located at the outside of the boss at the second cam top.
The both sides of described the 4th curved surface are the slope shape structure, and the boss that is opened in the second cam top is interior near center through hole one side.
Compared with prior art; Cooperation curved surface of the present invention is asymmetric; Cooperating between first surface and the 3rd curved surface through two dislocation cams, second curved surface and the 4th curved surface; Can satisfy equipment such as mobile phone and can open 0～360 degree, and satisfy equipment such as mobile phone open 0～360 have precompression when spending requirement, application area is wider.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment
A kind of dislocation type cam pack, this cam pack is made up of first cam 1 and second cam 2, and the centre of first cam 1 and second cam 3 is provided with center through hole.The structure of first cam 1 is as shown in Figure 1, and this first cam 1 is the concave shape structure, and the top is provided with the first surface 11 and second curved surface 12; Wherein, first surface 11 has two, and both sides are the slope shape structure; Be located at the outside of first cam, 1 top depression shape structure, second curved surface 2 also has two, is the crescent shape structure; Be located at the inboard of first surface 11, the position is more higher than first surface 11.First cam, 1 side is a convex structure for four jiaos, is plane structure all around.
The structure of second cam 2 is as shown in Figure 2; Second cam 2 is the convex shape structure, and the top is provided with a boss, and the 3rd curved surface 21 and the 4th curved surface 22 are set on this boss; The 3rd curved surface 21 is the crescent shape structure; Be located at the outside of the boss at the second cam top, the both sides of the 4th curved surface 22 are the slope shape structure, and the boss that is opened in second cam, 2 tops is interior near center through hole one side.The side of second cam 2 is a convex structure for four jiaos, is plane structure all around.
The present invention can be installed on the clamshell phone; Its structure is as shown in Figure 3; First cam 1 and second cam 2 are assemblied in the joint of mobile phone body 3 and cellular phone flip 4 respectively; First cam 1 and second cam 2 cooperatively interact through first surface 11 and the 3rd curved surface 21, second curved surface 12 and the 4th curved surface 22; Through axle and other part two cams are linked together then; Any one cam in fixing two cams makes first surface 11 and the 3rd curved surface 21 second curved surfaces 12 and the 4th curved surface 22 can open 0～360 and spend through meshing equipment such as satisfying mobile phone thereby rotate the another one cam then, and satisfy equipment such as mobile phone open 0～360 have precompression when spending requirement.
