[Prior Art] [0002] In a conventional hinge, a spring is often used as a damping function, and it can use its own elasticity to cause a reaction force or utilize a frictional force to generate a damping effect. It is common practice, for example, to spring the spring along the axial direction of the hinge, and to generate a frictional force with the hinge by pressing the hinge at both ends of the spring. This method can be applied to a lightly loaded mechanism such as a mobile phone or a notebook computer, and can withstand a weight of up to 100 kilograms. However, if it is used in a heavy load such as a server host or a large cabinet, the load demand is often Up to about 300 kilograms, it is not enough to rely on the friction generated by the ends of the spring. [New content] [0003] The purpose of the present invention is to provide a pivot structure that is resistant to high loads, which generates friction by the frictional force generated inside the coil spring. In order to achieve the above object, the present invention provides a pivot structure comprising a rotating shaft, a coil spring and a sleeve. The rotating shaft comprises a fixed section and one of the extending sections of the self-fixing section, and the outer diameter of the fixing section is larger than the outer diameter of the receiving section. One end of the coil spring is sleeved on the fixed section, and the other end of the coil spring is extended outside the receiving section. The sleeve is rotatably sleeved to the receiving section, and the coil spring is wrapped around the outer edge of the sleeve. [0005] Preferably, the aforementioned pivot structure has a sleeve with a hollow end of two ends 10120536^^^ A〇101 Page 3 / Total 20 pages 1013215531-0 M436744 _, 10Ϊ年.06^07 0 The core is replacing the column. [0006] Preferably, in the foregoing pivotal structure, the coil spring is a cylindrical coil spring. [0007] Preferably, the aforementioned yoke structure has a coil spring as a variable diameter coil spring. [0008] Preferably, the foregoing The frame shaft structure has a fixed section that is tightly fixed by the interference of the coil spring. [0009] Preferably, the aforementioned y-axis structure has a coil spring having a _ tightening direction in the circumferential direction. When the coil spring is twisted in the tightening direction, the inner diameter of the coil spring is reduced, and the coil spring is generated. A counter torque that is opposite to the tightening direction. [0010] Preferably, in the foregoing pivotal structure, when the sleeve rotates in the tightening direction with respect to the rotating shaft, the sleeve rotates the coil spring in the tightening direction by the static friction between the sleeve and the inner side of the coil spring, so that the spiral The inner diameter of the spring is reduced to tighten the sleeve. [0011] Preferably, in the foregoing frame shaft structure, the coil spring is driven by the rotation of the sleeve to continue to twist in the tightening direction relative to the rotating shaft. When the static friction force is maximized and the torque is less than the reverse torque, the coil spring is separated from the sleeve. Drive and return to no load. [0012] Preferably, the pivot structure has a socket formed in the fixing portion, and the coil spring includes a plug portion that is inserted into the socket to fix the coil spring to the fixing portion. [0013] Preferably, in the aforementioned frame shaft structure, the coil spring is fixed to the fixed section. 10120536^^^^ A〇101 Page 4 / Total 20 pages 1013215531-0 M43.6744 [0014] 101. 06. 0. 07. The shuttle is replacing the page. Preferably, the aforementioned pivot structure, its fixed section The outer diameter is slightly larger than the inner diameter of the coil spring, so that the spiral magazine is firmly fixed to the fixed section. [0015] Since the pivot structure of the present invention uses the inner side of the coil spring to force the sleeve to generate frictional force to achieve the effect of resisting mud, compared with the prior art, only the two ends of the spring resist the friction generating force, The frictional force generated by the created shaft structure is much larger than the conventional technology, and can withstand a larger load. Embodiments [0016] Referring to the first and second figures, a first embodiment of the present invention provides a pivot structure including: a rotating shaft 100, a coil spring 200, a sleeve 300, and a first connection.

[0019] The coil spring 200 has a tightening direction in the circumferential direction, for example, a right-handed spring is provided in this embodiment, when it is coaxially sleeved When the shaft 100 is rotated, the right-handed spring is rotated from the fixed section 110. The axial direction of 100 extends clockwise toward the first connecting end 121, so that the clockwise direction of the self-fixing section 110 toward the first connecting end 121 in the axial direction is the tightening direction (the tightening direction of the left-handed spring is counterclockwise), When the coil spring 200 is biased in the tightening direction by applying a torque, the inner diameter of the coil spring 200 is reduced, and a counter torque opposite to the tightening direction 4 is generated. When the coil spring 200 is twisted against the tightening direction The inner diameter of the coil spring 200 is enlarged. [0020] The sleeve 300 is preferably a hollow cylinder having a two-end opening, the inner diameter of which is not smaller than the outer diameter of the receiving section 120, and the outer diameter thereof is approximately equal to that of the coil spring 200.

One end of the sleeve 300 is a second connecting end 310, and the second connecting end 310 The radial section is preferably not circular, and a second stop surface 311 is disposed on the upper vertical axis. The sleeve 300 is rotatably coaxially sleeved with respect to the rotating shaft < 100 in the receiving section 120 and located at the coil spring 200. Between the inner side and the receiving section 120, the snail The spring 200 extends from the fixing section and is wrapped around the outer edge of the sleeve 300 such that the outer surface of the sleeve 300 contacts the inner side of the coil spring 200, and the edge of the second connecting end 310 is preferably aligned with the second positioning groove. [0021] Referring to the second to fourth figures, the first connecting member 400 is a metal piece, and a first opening 410 is formed through the first opening 410. The first opening 410 is sleeved on the first connecting end 121. The position of a connecting member 400 along the axial direction of the rotating shaft 100 is 1_53# single number Α 0101, page 6 / total 20 pages 1013215531-0 M436744 | 101_.06 month 〇 > The shape of the first opening between the first positioning groove 122 and the first stop surface 410 is not circular and conforms to the radial shape of the first connecting end 121, so that the first connecting member 400 and the rotating shaft 1 The helium supply rotates relative to each other in the circumferential direction. The first blocking piece 611 is a C-shaped metal piece which is inserted into the first positioning groove 122 to prevent the first connecting piece 4 from coming out along the axial direction of the rotating shaft 1 , and the first connecting piece 400 is removed. The first positioning groove 122 and the first stopping surface 124 are fixedly connected to the rotating shaft 1〇. Preferably, a first spacer 7U is interposed between the first blocking piece 611 and the first connecting member 400. φ [〇〇22] The second connecting member 500 is a metal piece, and a second opening 510 is formed through the second opening 51, and the second opening 51 is sleeved on the second connecting end 31〇. The second opening 510 is not circular in shape and conforms to the radial cross-sectional shape of the second connecting end such that the second connecting member 5〇〇 and the sleeve 3 are circumferentially rotatable relative to each other. The second baffle 612 is a c-shaped metal piece inserted into the second positioning groove 123 to fix the sleeve 3〇〇 to the rotating shaft 1〇 (), preventing the sleeve 300 from being along the axis of the rotating shaft The second connecting member 5 is fixed between the second blocking piece 612 and the second stopping surface 311.

The carrying platform (this creation is not limited to the locking, nor the fixing member 10 and the movable member 20). When the mainframe carrier (moving member 20) is pulled out from the casing (fixing member 10), the host carrier (the movable member 20) carries a "gravity", so that the sleeve 3 The tightening of the coil spring 2〇〇10120536^^ A〇101 Page 7/Total 2〇 Page 1013215531-0 M436744 The correction of the June 7th, 2011, when the page change direction is rotated relative to the rotation axis 100 'by the sleeve 300 The static friction between the inner side of the coil spring 200's sleeve 300 causes the coil spring 200 to twist in the tightening direction while applying a torque to the coil spring 200. The inner diameter of the coil spring 200 is reduced to tighten the sleeve 300, preventing The sleeve 300 is rotated relative to the rotating shaft in the tightening direction, and the position of the main body carrier (moving member 20) is fixed. When the main stage (movable member 20) is subjected to a pushing force to continue the rotation of the sleeve 300 in the tightening direction relative to the rotating shaft 1 , the static friction force is maximized to provide a torque less than the counter torque generated by the coil spring 200, then The coil spring 200 is released from the sleeve 300 and returns to an unloaded state. When the coil spring 200 returns to the unloaded state, its reverse moment is eliminated. The sleeve 300 again forces the coil spring 2 to twist in the tightening direction by the static friction force to press the sleeve 300. The present invention does not limit the first connecting member 4〇〇 and the second connecting connector'. The first connecting member 4 can also be locked to the movable member 20'. The second connecting member 500 is locked to the fixing member 1〇, but the spiral The tightening direction of the spring 2 is set to be the same as the weight of the movable member 20 to be supported for the pivotal structure of the present creation. [0024] Referring to the sixth figure, when the host carrier (moving member 2) is pushed into the cabinet (fixed_piece 10), the sleeve 3 turns the coil spring 2〇〇 against the tightening direction of the coil spring The 200 twist causes the inner diameter of the coil spring 2 to expand, and the friction between the screw 1 200 and the sleeve 3 is reduced and is easy to push.

[0027] The pivotal structure of the present invention increases the contact area with the inner side of the coil spring 200 to increase the contact area to increase the frictional force to increase the effectiveness of the mud resistance. The contact area between the inner side of the coil spring 200 and the sleeve 300 of the present invention. It is much larger than the contact area between the two ends of the coil spring of the prior art and the hinge. Therefore, the frictional force generated by the created beauty shaft structure is much larger than the conventional technology, so the load can be higher. The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the patent of the present invention. Other equivalent variations of the patent spirit using the present invention are all within the scope of the patent.
