Embodiment

For further understanding being arranged, now describe in detail for embodiment and conjunction with figs. for purpose of the present invention, feature and effect.The icon of this illustrated embodiment only is a preferable enforcement example of the present invention, general allly knows that the personage of this skill makes various variations and modification according to spirit of the present invention, must be included in the claim of the present invention.

See also Fig. 1, Fig. 2, hinge structure of the present invention includes a hinged arm device 10, a pivot base device 20 and is replaced device 30; This hinged arm device 10 includes a hinged arm 11, this hinged arm 11 is provided with a hinge portion 12, this hinge portion 12 has a circumference and pushes away and pull out the conical surface 121, and the expansion that makes these hinge portion 12 1 sides holds 122 diameters greater than other end end 123 the diameter that contracts, this hinge portion 12 is can high-abrasive material one-body molded and be coated on this hinged arm 11, and these hinged arm 11 relative these hinge portions 12 are provided with a tangent plane 13 (or other concavo-convex embedded structure), can not produce slide relative when making this hinge portion 12 be incorporated on this hinged arm 11, moreover, one end of this hinged arm 11 is provided with a tip hole 14, and end is provided with a concave ring groove 15 in addition, this tip hole 14 is in order to plug a tip bar 16, and this tip bar 16 protrudes out this hinged arm 11 both sides, and this concave ring groove 15 is embedded with a clasp 17, in order to produce the effect of replacing of location.

This pivot base device 20 includes a pivot seat 21, and this pivot seat 21 includes a pivot hole 22, and this pivot hole 22 relative these hinge portions 12 and be circumference and push away and pull out taper hole are in order to ccontaining this hinge portion 12 and produce and be pivoted relative to each other; This is replaced device 30 and includes a spring 31, and this spring 31 is formed with a trepanning 311, but this trepanning 311 of mat is sheathed on this hinged arm 11.

Be that hinge portion 12 with this hinged arm 11 wears the pivot hole 22 that is positioned at this pivot seat 21 during applied in any combination of the present invention, and the tip bar 16 of these hinged arm 11 1 ends of mat is fixed in (back is described in detail) on the parts, these hinged arm 11 location are not rotated, and this spring 31 is located at a side of relative this hinge portion 12 on this hinged arm 11, these spring 31 1 ends by this clasp 17 only support, and end is resisted against this pivot seat 21 in addition, and make the pivot hole 22 of this pivot seat 21 and the hinge portion 12 of this hinged arm 11 produce urgent conjugation, moreover, this spring 31 and this

pivot seat

21 and 17 of clasps respectively are provided with an

oiled washer

32,33, in order to produce preferable pivot and to replace effect.

In this way, but this pivot seat 21 mat application of forces and produce the operation that is pivoted relative to each other with this hinge portion 12, and because the replacing of 31 pairs of these pivot seats 21 of this spring, thus can make preferable urgent chimeric of this

hinged arm

11 and 22 generations of this pivot hole, and be beneficial to the stability of its pivot; Moreover, since this spring 31 continue to replace this pivot seat 21, so when this hinged arm 11 produces wearing and tearing or abrasion with this pivot hole 22, the power that pushes of 31 pairs of these pivot seats 21 of this spring can produce the benefit effect of removing of fine clearance at any time automatically, this pivot hole 22 is closely articulated with hinged arm 11 normal maintenances to be cooperated, easily produce lax when hinge structure uses in the future or locate bad phenomenon and exempt to deceive, this is structural one big characteristics of hinge of the present invention.

It practices hinge structure of the present invention except that can monolaterally being provided with, also can bilateral correspondence be provided with, as Fig. 3, Fig. 4 and shown in Figure 6, the bilateral setting of the present invention is applied to the schematic diagram of mobile computer, as shown in the figure, this hinged arm device 10 further includes a positioning seat 18, one side of these positioning seat 18 relative these hinged arms 11 is provided with a location hole 181, circular hole 182 in the middle of this location hole 181 includes and square hole 183 up and down, on this positioning seat 18 and be provided with two fixing holes 184, but these fixing hole 184 mat screw rods 185 are fixed on the main frame 41 of a mobile computer 40; And the tip bar 16 on an end of this hinged arm 11 and this tip hole 14 inserts in this location hole 181 and produce and prevent the location of rotating; And this pivot base device 20 further includes the fixing base 23 of an or concrete mutually integrally formed with this pivot seat 21, this fixing base 23 is provided with plural screw 231, but these screw 231 mat screw rods 25 are fixed on the screen 42 of this mobile computer 40 (as Fig. 7, shown in Figure 8), and make this pivot seat 21 and screen 42 one starts; One end pivot seat 24, this end pivot seat 24 can be one-body molded with this pivot seat 21, and it is provided with an axis hole 241, and this axis hole 241 can supply this hinged arm 11 insertion of end in addition, but and then this hinged arm 11 of stable position.

Fig. 7, shown in Figure 8 and for example, when this desires to open or cover the screen 42 of mobile computer 40, the operation that mat is pulled this screen 42 can be pivoted relative to each other with these hinge portion 12 generations by this pivot seat 21 of interlock, and then produces the arbitrarily stable locating effects that pivot smoothly of this screen 42.

Continue and see also Fig. 5, this pivot seat 21 and adjacent 18 of positioning seats are provided with a gap A, and contracting of this hinge portion 12 is provided with a gap B between end 123 and these 22 ends, pivot seat 21 corresponding pivot holes, when this hinge portion 12 produces abrasion with this pivot hole 22, the pushing and pressing effect of this spring 31 of mat and make this gap A, B that one operating space of advancing to remedy is provided.

In sum, its its specific structure feature of hinge structure mat of the present invention, really can reach the every requirement of goal of the invention, and significantly improve the greatest practical effect of common product, more not seeing has the product of same structure feature openly to sell, the real establishment important document that has met patent of invention of obvious the present invention, the application of patent is proposed in accordance with the law, earnestly asking and grant accurate this case patent early, reward compatriots the legislative spirit of invention to show Patent Law, is that institute is to expecting.
