Abstract

The utility model relates to a hinge device used to assemble on a mobile phone, a personal digital secretary or a dressing case in order to stably open or close a hinged outer cover, and consists of a sleeve, a compressed spring equipped inside the sleeve, a first cam, a second cam which is meshed and revolved with the first cam to locate at an opening and a closing position, and an assembly shaft connecting the components in series. By mean of the module structure, through the tangent plane of the sleeve surface and the tangent plane of a combination seat connected with the second cam, the utility model can control the opening and closing operations of the outer cover; can obtain the effects of a fast, stable and convenient assembly, and a reduced material management burden.

Description

Hinge means

Technical field

The utility model relates to a kind of hinge means, be meant that especially a kind of modularization, volume are little, and structure is firm, is used to be assembled in small appliances such as mobile phone, individual digital secretary or style strip box, the hinge means that can provide the enclosing cover that articulated stably to raise or cover.

Background technique

The hinge means relevant with the utility model, can be with reference to No. the 5661797th, 5983083,6209173, U. S. Patent etc., these hinge meanss are assembled on the mobile phone, be used for raising and covering of an enclosing cover, its structure design is outer to be to utilize the distortion of spring sheet that turn energy storage afterwards is provided, and reaches the operation of raising and covering.But these known hinge meanss are because the various not only assembling of structure is difficult for and cost is high, and for the product specification trend of miniaturization day by day, provide in the mode of spring sheet radial distorted as if restoring force is difficult to be satisfied.Another kind of cooperate cam-actuated design with pressure spring, can reach the operation of raising and covering equally, and the trend that replaces is arranged, relevant structure design can be with reference to No. the 5109571st, 5678206,5996178, U. S. Patent etc.Yet, the assembling of this type of hinge means be each assembly is organized respectively upright to mobile phone, therefore, except that assembling operation seem loaded down with trivial details, between hinge MANUFACTURER and the mobile phone MANUFACTURER transport with material on management all cause sizable puzzlement.

Summary of the invention

The purpose of this utility model, be to provide a kind of modularization, volume little, be fit to be assembled on small appliances such as mobile phone, individual digital secretary or the cosmetic container, be used to control the operation that its lid is raised and covered, it is convenient, firm to reach assembling, and reduces the hinge means of bearing in the handling of goods and materials.

The purpose of this utility model realizes by following technological means: a kind of hinge means, comprise a sleeve, a pressure spring, first cam, second cam and an assembling axle, sleeve one end opening, the other end is provided with perforation, the corresponding both sides of opening are the tangent plane, and the tangent plane is provided with corresponding guide groove; The belly that is assembled in the sleeve in the lump with pressure spring and is resisted against first cam of pressure spring is provided with assembly hole, and its surface with respect to the guide groove of sleeve is provided with guide block; With first cam-engaged and mutually turn be positioned at and raise the position and be connected a conjunction base with an end that covers second cam of position, the corresponding both sides of conjunction base are the tangent plane, belly forms square fish eyelet; Assembling axle one end has the head identical with the fish eyelet configuration, and the other end then passes the outer side wall that is locked in sleeve behind fish eyelet, assembly hole, the pressure spring.

Described hinge means, the fish eyelet of conjunction base are long-round-shape.Described hinge means, an end and sleeve outer side wall that the assembling axle that mat riveted mode locks is locked are provided with plastic spacer and metallic shim.Described hinge means, first cam have corresponding first recess and first protuberance in 180 degree positions, and second cam is provided with second recess and first protuberance that is complementary engagement with it with respect to first recess and first protuberance of first cam.

Advantage of the present utility model is: 1, modularization, volume are little, are fit to be assembled on the small appliances, are used to control the operation that its lid is raised and covered; 2, it is convenient, firm to reach assembling, and reduces the effect of bearing in the handling of goods and materials.

Embodiment

Describe structure of the present utility model in detail below in conjunction with accompanying drawing.

As shown in Figures 1 to 4, hinge means 1 of the present utility model comprises structures such as sleeve 2, pressure spring 3, first cam 4, first cam 5 and assembling axle 6, its middle sleeve 2 one ends are opening 20, the other end 21 is provided with perforation 210, opening 20 corresponding both sides are tangent plane 22, and tangent plane 22 is provided with the guiding of corresponding guide groove 23 as first cam, 4 lateral displacements.Pressure spring 3 is assembled in the sleeve 2, and the one end is resisted against the inwall with perforation 210 of sleeve 2, and the other end then leans with first cam 4.First cam 4 is assembled in the sleeve 2, the one end is resisted against pressure spring 3 as previously mentioned, it is corresponding with the perforation 210 of sleeve 2 that belly is provided with assembly hole 40, is provided with guide block 41 with respect to the surface of the guide groove 23 of sleeve 2, and mat guide block 41 can slide on guide groove 23 when first cam 4 is driven.In addition, first cam 4 has mutual correspondence at first recess 42 of 180 degree positions and also corresponding mutually first protuberance 43 in 180 degree positions.Second cam, 5 one ends are provided with conjunction base 50, the corresponding both sides of conjunction base 50 are the tangent plane, and belly forms square fish eyelet and is used for for 6 assemblings of assembling axle, the other end is provided with and first recess 42 of first cam 4 and corresponding second recess 52 and second protuberance 53 (as shown in Figure 4) of first protuberance 43, and be complementary engagement with it, can be positioned at 180 degree turns mutually and raise the position or cover the position, that is first cam 4 and second cam 5 are whenever crossed second protuberance 53 (or first protuberance 43) by first recess 42 (or second recess 52) mutually and are then made one-time positioning.Assembling axle 6 one ends have the head 60 identical with fish eyelet 50 configurations, and the other end then passes fish eyelet 501.Assembly hole 40, pressure spring 3, and with 62 assemblings of plastic spacer 61 and metallic shim, mat plastic spacer 61 prevent to assemble axle 6 directly with the outer side wall friction of sleeve 2, mat metallic shim 62 can make assembling axle 6 firmly riveted lock on the outer side wall of sleeve 2.

As shown in Figure 2, be a single modular assembly after above-mentioned each assembly assembling of the present utility model, can be assembled into easily on the mobile phone, as shown in Figure 5, drive-connecting shaft 71 on the lid 70 of mobile phone 7 only need be reserved a keyway 72, during assembling the guide block 41 of first cam 4 is aimed at and the drive fit assembling, simultaneously, the group-connecting groove (not shown) that second cam 5 is assembled in this machine 73 of mobile phone 7 can be finished assembling operation.In this way, when lid 70 being raised or covering operation, first cam 4 and second cam 5 are promptly crossed second protuberance 53 (first protuberance 43) by first recess 42 (second recess 52) mutually and are made one-time positioning.Therefore, the above-mentioned modular single component of the utility model, it is convenient, firm to reach assembling, and reduces the effect of bearing in the handling of goods and materials.
