Description

Shaft structure with damping function

The present invention provides a rotating shaft structure with a damping function, in particular, a damping means is provided between the sleeve and the sleeve outside the rotating shaft. When the second plate is released, the acting portion of the second plate drives the transmission portion of the shaft to Rotate back, and then rotate the belt with the outer sleeve, and cooperate with the damping means to increase the resistance when turning back, to avoid the moment when the second plate is dropped.

According to the mechanism, many mechanisms that need to move, pull, move or slide are usually pivoted by the rotating shaft for convenient rotation and actuation. For example, the flaps and slide rails used for the switch of the door panel or the window are used. The rotating shaft of the pivoting roller or the rotating shaft between the inner layer of the industrial computer case and the chassis is pivoted between the two plates through the rotating shaft, so that the two plates can rotate relative to each other.

However, the current use of the shaft between the two plates in the actual application, implementation, there are the following shortcomings, for example: the industrial computer chassis inside the layer will store a plurality of hard disk, when the maintenance personnel in the process of repairing the hard disk In the middle, the laminate will be opened upwards, and the hard disk will be pulled out for replacement or repair work. However, due to the large number of hard disks, the load of the laminate will be increased, if the maintenance personnel have not stabilized the laminate or have a sliding hand. When the situation occurs, the laminate will fall down rapidly due to gravity, causing a situation of over-rotation or collision, resulting in damage to the hard disk stored in the chassis or inside, thereby causing a lot of property damage.

Therefore, how to solve the above problems and shortcomings in the past is the direction for the relevant manufacturers engaged in this industry to research and improve.

Therefore, in view of the above-mentioned problems and deficiencies, the creators have collected relevant information, and through multi-party evaluation and consideration, and through years of experience accumulated in this industry, through continuous trial and modification, we have designed such a shaft with damping function. The new type of structure was born.

The main purpose of the present invention is to provide a perforation inside the sleeve of the rotating shaft, and a positioning portion is arranged at the bottom of the sleeve, and a shaft is disposed in the through hole, and the shaft has a head located above the sleeve, and A shaft penetrating into the perforation is arranged under the head, and a transmission portion is arranged below the shaft body, and an outer sleeve is arranged on the head, and an accommodation space for the sleeve is formed inside the outer sleeve. And a damping means is disposed between the outer sleeve and the sleeve, and at least one side of the first plate is provided with a hole for fixing the positioning portion and for the transmission portion to pass through, and the second plate is provided on at least one side of the second plate. The actuating portion is combined with the driving portion. When the second plate rotates, the actuating portion rotates the driving portion of the driving shaft to rotate with the outer sleeve, and when the second plate is released, the actuating portion drives the transmission portion back. Rotate, and then rotate with the outer sleeve back, and cooperate with the damping means to increase the resistance of the outer sleeve when rotating back on the sleeve, so as to avoid the occasional drop of the second plate.

Such simple modifications and equivalent structural changes shall be included in the scope of the patent of this creation and shall be combined with Chen Ming.

When the shaft 1 is to be coupled to the second plate 3, the sleeve 13 can be pulled upwardly, so that the transmission portion 123 of the shaft 12 is received upward in the receiving groove 1111 of the through hole 111 of the sleeve 11. Further, the elastic member 124 is compressed and deformed, so that the second plate member 3 can be placed under the first plate member 2, and the actuating hole 311 of the actuating portion 31 is aligned with the hole 21 of the first plate member 2, and then the hole can be placed. The sleeve 13 is opened outside the shaft 1 to elastically reset the elastic member 124, so that the transmission portion 123 of the shaft 12 passes through the through hole 111 of the sleeve 11, thereby being inserted into the operating hole 311 of the actuating portion 31. At this time, the plurality of abutting faces 1231 at the side of the transmission portion 123 will abut against the plurality of abutting faces 3111 contacting the inner wall surface of the operating hole 311, and at the same time, the abutting ends 1241 of the elastic members 124 will abut. The top surface of the receiving groove 1111 of the through hole 111 and the top surface of the transmission portion 123 are disposed so that the transmission portion 123 of the shaft 12 is within the operating hole 311 and is not easily detached.

When the user wants to perform maintenance or disassembly, the user can pull the second plate 3 into an open state, and the second plate 3 will rotate with the rotating shaft 1 as an axis, and at the same time, The actuating portion 31 of the second plate 3 rotates the plurality of abutting faces 3111 in the actuating hole 311 to drive the plurality of abutting faces 1231 of the transmission portion 123 to rotate with the shaft 12 and the outer sleeve 13, and the outer casing A damping means 14 is disposed between the sleeve 13 and the sleeve 11, so that the rib 142 of the damping means 14 is rotationally displaced from the recess 141 into the other recess 141 as the outer sleeve 13 rotates, and when the user When the second plate 3 is released, the second plate 3 will be rotated back. At this time, the rib 1 of the damping means 14 42 will be rotationally displaced from the other groove 141 into the groove 141, because the rib 142 will first enter the groove 141 and then detach from the groove 141, so that the second plate 3 can be rotated back. The resistance at the time, in turn, provides a damping function to cause the second sheet 3 to slowly rotate back, thereby avoiding the moment when the second sheet 3 is instantaneously dropped, thereby preventing the articles carried on the second sheet 3 (eg, hard Disc) A collision, scratch, or damage.

The plurality of resisting surfaces 3111 are mutually abutting structure, so that the shaft 12 can rotate with the second plate 3 rotating, but in practical applications, the transmission portion 123 of the shaft 12 of the other embodiment can also pass through the riveting groove. 1232 is riveted into the actuating hole 311 of the actuating portion 31 to be stably coupled, so that when the second plate 3 is rotated, the shaft 12 can also rotate with it, but the transmission portion 123 and the second portion of the shaft 12 are related to The actuating portion 31 of the plate 3 is combined in a plurality of ways. When only the second plate 3 is rotated, the shaft 12 can be rotated at the same time, so that the simple modification of the present specification and the graphic content is used. And the equivalent structural changes shall be included in the scope of the patent of this creation, and shall be combined with Chen Ming.

The above detailed description is intended to illustrate a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and other equivalents and modifications may be made without departing from the spirit of the invention. Changes are to be included in the scope of patents covered by this creation.

In summary, the above-mentioned shaft structure with damping function is actually able to achieve its efficacy and purpose when it is actually implemented and applied. Therefore, this creation is a practical and excellent research and development, in order to meet the requirements of the new patent application.爰Proposing an application in accordance with the law, I hope that the trial committee will grant this case as soon as possible to protect the hard work of the creators.
