4. Description of Creation (1) [Technical Field to which the New Type belongs] This creation is about the re-improving structure of the elastic tight shaft, especially a kind of tight pressing state that can be maintained between the pivot and the sleeve, and at the same time both Prevents the back-off function during use and prevents the grease shaft from leaking out during assembly and causing dirty shaft structure. [Prior art] The flexible and tight structure of the rotating shaft is commonly used, as shown in the patent case of the Republic of China Patent Gazette No. 477434 "Notebook computer stepless rotating shaft" (Application No. 8922 0 64) Among them, Fig. 3 reveals the structure of two female and male shaft cylinders. The surface of the wall of the shaft of the locust shaft is provided with a cylindrical sleeve with a tightly fitted pit in one end. The shaft is shown in the figure. The deformation amount of the part can keep one side of the soil sentence) and the cylinder, and the side of the rear end can ensure that the fixed system and the cylinder are dragged. The mechanism design of the fixed part except rotation is small and the stress concentration is prolonged. One end of the male shaft cylinder is provided with at least one ring or more and a completely cut cylinder is arranged in the cylindrical sleeve to accommodate the cylindrical pivot. This structure is uniform, so It combines the fixed part with the shape of the locomotive shaft, and makes the tube hold an appropriate elastic deformation axis to eccentrically combine, which causes the movement of the 'disturbance, and the fixed part and the tube are obvious, which is not conducive to the bay shape on the mechanism; [ The area shaft is in the oil-conducting groove and in the gap, and the female shaft cylinder is provided with a cylindrical pivot to form a stepless rotation of the same-shaped pivot. It is in front of the notch. However, when the cylindrical pivot rotates, the stability of the contact part of the practical pivot and the service life are caused.

In addition, it is the first group of Zhu to unveil J. The other is that it is a cylindrical frame.

M244348 keep the same amount of the same situation, but cut the groove, by appropriate bullets to concentrate, pick the case regardless of the grease guide, when lubricating friction heat generation assembly, the mouth, pushing the spilled dirty creator Shen Shen, Later, I still get rid of the disappearance image, and the rotation of the habit is to focus on the axis, but to make the cylindrical shape on the cylindrical pivot to deform the cylindrical pivot, the short contact area is the third figure. Or the oil grooves are all provided with grease due to excess, or long-term pivoted from the barrel of the female shaft to the cylindrical pivot and dirt. Although the case No. 91214662 has been resolved, it is possible that the overall structure will be more axial structure and creation due to extreme circumstances. Some shortcomings should be researched to avoid the gap between the front and back of the pivot and the fixed part. However, this is a mistake. The male shaft raised in the figure is raised at the fixed part of the grease-shaped sleeve. The description of the creation (2) The elastic deformation of the shaft and the fixed part with different rotation paths can be maintained across the cross to avoid it. In addition, stress, it contains the lubrication periphery, so the excess or grease will be lacking in the area of the pivot, and there is a case of improvement. When using it for a period, even the pivot can be expected to be loose. People are born. [New content] The purpose of this creation is to provide a pivot that is mainly caused by the eccentricity of a shaft sleeve. There is a structure with a front and rear side structures that is still difficult to reveal. On the oil groove, the lubricating edge after liquefaction, or the part connected by the cylinder, is made (No. 534 1 87). The learner has many disadvantages, but the elasticity of the shaft is weak, and there is looseness. It is imperative to make it less perfect. The previous case still has the above-mentioned shortcomings, and finally has this creation. An elastic and tight pivot twister improved structure, with a recessed accommodating portion at the end, where

| 雠 圆! 1_Hidden_ | I 8 | ___ 圆 1 国 1_ II M244348 g, Creation Instructions (3) There is at least one ring extension in the interior, and a concave one with a recessed part around the outer periphery of the inner wall. The main purpose of preventing the bushing from being lubricated in the accommodating part during friction use is clearly shown in the following reference to the combined structure of the first figure before the implementation of the embodiment, wherein the bushing portion 11 can be provided with lubricating grease. The fixed part 1 2 has a recessed longitudinal cut slot 2 2 and a stop more than one turn 2 5 is connected to the pivot to insert the hollow part, and the peripheral ring is provided with a cooperation, so that the hollow pivot is caused by the elastic channel, so that two, Not outward. The detailed structure of the creation is made] and the sectional structure of this creation and the lubricating channel of the extension are provided for containing the lubricating grease storage portion; one end of the corresponding pivot is also provided with a longitudinal cut groove Connected to the outside and hollowed out above the ring channel, the ring channel pivoted by the ring channel and the outer part of the accommodating part can not only increase the fatigue-relieving stop function, but also cooperate with the lubricating grease. Those who can still maintain the leaked and dirty structure despite being pushed, can fully understand the original structure, application principle, function and effect: The lack of the three-dimensional structure of the three-dimensional structure mainly includes the creation of the composition. : One end of the shaft is provided (or not provided). The shaft is provided with a plurality of empty portions 21, which communicates with the outer ring groove 26, and a fixed portion 2 4

There is a hollow part 2 1 for fixing the annular extension sleeve 1 inside, and the hollow pivot 2 is another. The fixing mentioned above is provided with a hole in the exploded view of the anatomical sleeve 1 and the recess of the pivot recess. 1 2 1 The side and the part 21 will not be shown in the drawing. The parts such as the shaft 2 and the part 11 are redundant. According to the second figure, the two parts can be clearly explained. In the housing 1, a fixed part 12 is accommodated, and the pivot 2 is set at the end to the base diameter, and the peripheral part is also provided with a duplicate part at the peripheral part 24. The extended surface is recessed and fixed for expansion

Page 8 M244348 Fourth, the positioning hole 241 of the creative description (4) is provided with a first recessed ring to eliminate the recessed groove 2 3 The third figure is inside the accommodating part 11 of the exploded view of the structure, and the shape is sharp. When the concave ring groove 23 of the pivot 2 is deformed, the entire periphery of the grinding joint should be deformed (to avoid the constant pressing force of the pivot, and the inner surface of the sleeve 1 is recessed for more than one turn 11). As a result, the pivot shaft 2 is produced in the original sleeve portion 11 without any disengagement. If a small portion of the "end portion of the pivot shaft 2" is contained, it will have the same effect and be pushed out to prevent the shaft sleeve from being contaminated. 1 and pivot and pivot 2 are in the base groove 2 3, and the structural combination of the pivotal periphery of the pivot vehicle is created. When combined, the longitudinal slot 2 2 can be used to maintain proper elasticity and benefit The pivot 2 is integrated with the axial surface element, and the strength is reduced, so that the pivot 2 2 is connected with the stopper 25 to prevent it from falling off after long-term use; and the slot 2 of the pivot described above can grow larger. It is buckled against the friction shaft sleeve 1. The lubricating grease surface in the lubricating channel 1 1 1 11 It can just block the excess groove groove 2 3, so it can effectively multiply the lack, and increase the perimeter of the constructor and the stop 2 of the shaft 2 and the stop 2 through the appropriate image. Extend the absorption pivot 2, and the contact low pivot 2 provided on the sleeve 1 maintains a part that is not easy to change. The end 2 of the pivot 2 and the hollow portion 2 1 cooperate with the aforesaid axis coefficient to reduce the heat treatment of the connecting part 25. The base surface of the compressed pivot 2 that is flattened into the sleeve 1 in Fig. 3 is uniformly elastically shaped at the grinding stop 25 (2), resulting in long fatigue due to elastic fatigue. After use, the elastic pivot knot is excessively accommodated in the shaft sleeve 1. When assembling, the sliding grease is pushed into the accommodation portion and the groove ring channel 26 of the pivot 2 is also avoided to prevent excess grease from being caught by the end. And the lubricity

Page 9 Fourth, the creation instructions (5) The attached sectional drawing and the first best peripheral surface have no lubrication effect, the constructor. From the above, there is a balance that leads to a break-out and progress. However, the above J is not intended to be used for limitation.
