The specific embodiment

See also Fig. 3 to shown in Figure 7, axle center 1 of the present utility model is that a section is the polygonal body of rod, and the body of rod that intercepts a suitable length is as matrix 11, this matrix 11 comprises a planar portions 111 at least, this matrix 11 is on the planar portions 111 of the first side section, at least one fixing hole 12 of lateral direction penetrating, and the tow side section of this matrix 11 forms a spiro rod section 13.

The matrix 11 that the utility model is taken, 11b, 11c, its section configuration of 11d are to be a hexagon (shown in Fig. 3 A, Fig. 3 B, Fig. 3 C), quadrangle polygon or semi-circular shapes as shown in Figure 6 such as (as shown in Figure 5), or have two relative parallel planes as shown in Figure 7.

The axle center 1 that the utility model disclosed, as shown in Figure 3A, be that intercepting one section is the body of rod of non-cylindrical as matrix 11 earlier, shown in Fig. 3 B, the first side Duan Zeyi planar portions 111 of this matrix 11 wears at least one fixing hole 12, shown in Fig. 3 C, the tow side section of this matrix 11 is processed to form a spiro rod section 13 for another example, promptly finishes axle center 1 finished product shown in the utility model.Because the matrix 11 that the utility model is taken, its outer rim has had at least one planar portions 111, therefore can on this planar portions 111, directly carry out the boring processing (, easily producing the deflection hole) of fixing hole 12, be vertical configuration to guarantee fixing hole 12 and this planar portions 111 as directly on cylinder, holing.Make the utility model in manufacturing process, just do not need as prior art, must be by the Milling Process program, to obtain this planar portions for boring, make manufacturing process of the present utility model can exempt the procedure of processing of this milling, to reduce manufacturing cost and to reduce manufacturing time.

The utility model is being installed, as shown in Figure 4, available fixed screw 2 passes in the fixing hole 12 in this axle center 1, securely be bolted in the first side section in this axle center 1 with first member 31 with a hinge, and the spiro rod section 13 of this axle center 1 tow side section, make its pivot be placed in the pivot hole 321 of second member 32 of this hinge, and make its outer end hold-down nut 33 that is spirally connected, with packing one brake assemblies 34, make this axle center 1 can comply with pivot hole 321 turns of this second member 32, and this brake assemblies 34 is stably parked on the angle of being rotated.Above-mentioned brake assemblies 34 grades are used for the existing structure element on the hinge, because of belonging to existing structure, so do not give unnecessary details.

As Fig. 3 C and shown in Figure 4, the axle center 1 shown in the utility model at the root of this spiro rod section 13, also forms a shoulder block 14, outside other element that is resisted against hinge; In the outer rim of this spiro rod section 13, form an interlocking face 131 in addition, to be embedded in this brake assemblies 34 these brake assemblies 34 rotations of linkage identically.

Axle center 1 of the present utility model can be applicable in the display hinge of liquid crystal screen display, mobile phone, P.D.A, electronic dictionary or other associated electrical product.

It is matrix with the cylinder body of rod that this practicality newly can improve present prior art, must be in manufacturing process, mode with milling, on its periphery, form the imperfect manufacture of a planar portions, and the utility model is that directly intercepting one body of rod that is polygon section or tool one planar portions is its matrix 11, and exempts prior art " milling " procedure of processing in processing procedure, has the reduction manufacturing cost, reduce advantages such as manufacturing time, have novelty, creativeness, practicality.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
