New description: [Technical field of new type] Especially refers to a pivot structure with a pivotal structure of the tongue-and-pin type shaft. [Prior Art] In the normal life, in order to make the folded object often have a structure of a shaft structure between the two objects, most of them are composed of a male shaft and a female body: 2, the shaft joint contains - Part with a shaft, and the main shaft: by =: part and - shaft. Under the general condition, the bus ==: the shaft tube that is coupled to the parent shaft, and the joint of the male shaft is the sister: the joint of the two L Zhu mother shaft is coupled to the second object: therefore, the object =?! The axis is rotated about the center, and the first-to-object is opened and closed to form the above-mentioned folded object. In the practical application level, in order to make the male shaft provide torque according to the actual torque demand in two different directions of rotation (positive rotation direction, reverse rotation direction), ("double or two packs" coated type (four) to bidirectional The utility model covers the male shaft, so that the rotation torque in the direction of the covering direction is large, and the torque in the reverse coating direction is small, that is, the characteristic of the stomach is “the lightness of the stomach” is the design basis, so that the control shaft is used as the male shaft edge. The twist provided by the above two different rotation directions (square rotation; direction and reverse rotation direction) with respect to the rotation of the female shaft. = Bu, in the prior art, the coated shaft cylinder is usually made of a punching plate. In this structure, although the frictional force between the shaft and the female shaft is provided - the basic torque, and the basic torque is large when the cover is = 3 M364783, the reverse is small. At the same time, the function of closing the lock position can be provided by the basic torque set at the time of revolution. ^The axis between the axis and the clamping element of ^ rfq, on the other hand, due to the influence of concentricity and vibration factors on the axis of the shaft after the rotation of the male axis relative to the parent axis, the two sides are non-absolutely compared. The middle section of the cladding section mill 4: 2 section wear amount usually provides a decreasing rate of the torsion provided by the side cladding section, which is greater than the decreasing rate of the torsion provided by the section. In this way, after the parent shaft has been rotated many times, it will inevitably cause a sudden increase in the ratio of the entire axis. The basic torsion of the body is decremented by η/ί double-wrapped shafts. * After the common axis is rotated relative to the parent axis, it is affected by non-absolute concentricity and vibration factors. Usually, the inside of the cladding area is larger than the inside, so that it is easy to cause the rate of decline of the twist provided by the outer cladding section, which is greater than the decreasing rate of the torsion provided by the inner cladding section. In this way, after the male shaft is rotated a plurality of times with respect to the female shaft, the overall basic torque is suddenly reduced. In this case, the creator of this case has to develop a new pivot structure, in order to adjust the difference between the positive and negative directions, and to balance the various sections relative to the shaft. Wear rate. [New content] The technical problems and objectives to be solved by this creative work: ~Overview of the above-mentioned, in the coated shaft barrel of the pivot structure of the prior art, especially the three-pack or double-packaged shaft cylinder In general, the wear of the coated sections on both sides or the outside is generally larger than that of the inner or inner cladding sections, resulting in a sudden increase in the overall basic force decline rate of 4 M364783. Accordingly, the main purpose of the present invention is to provide a pivot structure having a tongue-and-press type shaft cylinder, which is such that the less expensive cladding section is at a first center distance from the central axis of the barrel of the barrel, and The cladding section with less friction is replaced by a reversely wrapped tongue and the tongue is spaced from the central axis of the barrel of the barrel by a second center distance less than the first center distance. - The technical means to solve the problem in this creation: - The technical hand ® segment used in this creation to solve the problem of the prior art provides a pivot structure with a tongue-and-press shaft. The pivot structure includes a shaft and a barrel. The shaft includes a base rod and a plurality of connecting pieces that are sleeved on the base rod. The shaft barrel covers the shaft and has a shaft center shaft and includes at least one cladding section and at least one pressure tongue. The cladding section encloses the shaft in a first cladding direction and is spaced a first center distance from the central axis of the barrel. The tongue is attached to the cladding section and covers the shaft in a second cladding direction opposite to the first cladding direction and is spaced from the central axis of the barrel by a second center distance less than the first center distance. In the preferred embodiment of the present invention, the barrel is a three-pack wrap type; the barrel, wherein the two cladding sections are on both sides, and the other cladding element in the middle is the above-mentioned tongue. Thereby, an adjustment torque is provided by the tongue to adjust the forward and reverse rotation torque-force difference of the shaft relative to the barrel, and the wear rate of the cladding section and the tongue relative to the shaft can be balanced. This creation contrasts with the efficacy of the prior art: From the above, it can be seen that, in comparison with the pivot structure described in the prior art, in the pivot structure provided by the present creation, the wear rate is relatively small (with the first package) The second cladding direction opposite to the direction of coverage) the covered 5 M364783 cladding section 'sends the other cladding element (ie, the tongue) to take the pressure and the tongue is spaced from the central axis of the barrel by less than the above The second center distance of a center distance. Therefore, in the use of the tongue to adjust the torque difference between the direction of the positive rotation and the direction of the reverse rotation, it is also possible to reduce the wear rate of the cladding section having a large wear rate on both sides by increasing the consumption of the tongue. Thereby, the wear rate of each of the covering sections and the tongues relative to the two can be effectively balanced, and after the male shaft is rotated a plurality of times with respect to the female shaft, the basic torque is kept stable without being difficult to reduce, and thus long The service life of the pivot structure. The specific embodiments used in the present application will be further illustrated by the following examples and drawings. She [Embodiment] Due to the pivotal structure provided by this creation, it is possible to: 'The combination of the implementation is even more victorious:: Force = two-speaking' only lists one of the preferred embodiments for Taichuang 2: The body exploded view, the second figure shows the three-dimensional exploded view of the base rod after the series connection in the preferred embodiment.

The member 213, forming the above-mentioned covering sections 213 and 214, and pressing the M364783 tongue piece 215' to form the above-mentioned pressing tongue 215. Referring to the fifth figure, which shows the preferred embodiment of the present invention, the shaft barrel Covering section and tongue Schematic diagram of the covering relationship of the shaft covering rod. As shown in the figure, since the second center distance R2 is smaller than the first center distance R1, the drawing rod 11 is pushed and the shaft center axis A is deviated from the shaft center axis B. In all relevant illustrations of the embodiment, in order to clearly indicate the cladding relationship of the cladding section and the tongue-wrapped shaft, the difference between the first center distance R1 and the second center distance R2 is particularly enlarged. In the practical application level, in order to avoid excessive φ transverse shear stress caused by eccentricity, the second center distance R2 is only slightly smaller than the first center distance R1, and the shaft center axis A also coincides with the central axis B of the shaft cylinder. A special explanation is given together. Please refer to the sixth figure, which shows the relationship between the cladding relationship and the torsion of the coated section and the tongue-wrapped shaft when the shaft rotates relative to the barrel in a rotating direction. As shown in the sixth figure, when the shaft 11 rotates relative to the barrel 21 in a direction 15 of rotation along the covering direction 13, the covering section 213 is deformed to make the covering section 213 more tightly wrapped. The shaft 11 raises the above basic torque. However, the φ shaft 11 also causes the tongue 215 to deform in the direction of rotation 15 opposite to the cladding direction 14 to relax the tongue 215 and reduce the above-described basic torque. Under the influence of the growth and contraction of the basic torque, the basic torque described above can be adjusted. Conversely, referring to the seventh figure, it is a schematic diagram showing the relationship between the covering relationship of the covering section and the tongue-wrapped shaft and the torque change when the shaft is rotated relative to the barrel in the other direction of rotation. As shown in the seventh figure, when the shaft 11 rotates relative to the barrel 21 in the other direction of rotation 16 against the covering direction 13, the covering section 213 is deformed to loosen and reduce the covering section 213. The basic torque described above. However, the shaft 11 also sways the tongue 215 in the same direction of rotation as the cladding direction 14 by 16 M 364783, so that the genus 2 5 争 $ 其 其 其 其 其 f f f f f 而 而 而 而 而Improve the torque of the ^.

Thereby, the wear rate of the cladding sections 213, 2U for the shaft 11 can be effectively balanced, and thus the male shaft 1 is opposite. ^, after the shaft 2 untwisted many times, the overall basic torque is kept flat. It will not suddenly drop sharply, and thus extend the life of the pivot structure by 10 M364783.
