The damping member 2 is preferably formed by surrounding the sheet 21 made of metal, but in practical applications, the damping member may also be formed by surrounding the sheet 21 made of plastic or other flexible sheets 21.
The diameter of the sheet body 21 of the damping member 2 is slightly larger than the diameter of the accommodating groove 11 of the sleeve 1, so that when the damping member 2 is installed in the accommodating groove 11, the outer side surface of the damping member 2 can be elastically supported against the inner side surface of the accommodating groove 11 of the sleeve 1, thereby providing an elastic resistance, however, when the damping member 2 is installed in the accommodating groove 11, the outer side surface of the first end surface 22 of the damping member 2 does not contact with the inner side surface of the accommodating groove 11.
Referring to fig. 5, 6, 7, 8, 9 and 10, which are a side sectional view before the plate is combined with the plate, a top sectional view when the fixing element is locked, a side sectional view after the plate is combined with the plate, a top sectional view before the fixing element is released, a top sectional view during the fixing element is released, and a top sectional view after the fixing element is released, as can be clearly seen from the figures, the present invention is applicable to a computer server, a telecommunication office cabinet, a work machine or other equipment or device composed of a panel set, a drawer, a keyboard tray, etc., the sleeve 1 can be installed in the hole 41 of the external plate 4 by using the positioning portion 12, and is stopped at the top surface of the hole 41 by the position-limiting ring 121 of the positioning portion 12 to be positioned, and after the sleeve 1 is positioned on the external plate 4, the hole 41 of the external plate 4 can be aligned with the positioning hole 51 of the external plate 5, when the fixing element 3 is locked, the head 31 of the fixing element 3 can rotate clockwise by using a bare hand or a hand tool, so that the abutting block 34 of the fixing element 3 can enter the through hole 210 of the sheet 21 of the damping member 2 and rotate clockwise along the inner wall surface of the sheet 21, and when the abutting block 34 rotates to the inner side of the first end surface 22 of the damping member 2, the first end surface 22 is supported outwards, so that the rotation can be performed smoothly, and after the forward rotation is performed repeatedly, the external thread 331 on the surface of the locking part 33 and the internal thread 511 on the inner wall surface of the positioning hole 51 can be screwed together to form a combined positioning, so that the locking operation is completed.
The positioning portion 12 of the sleeve 1 is preferably installed in the hole 41 of the external plate 4 and is stopped at the top surface of the hole 41 by the position-limiting ring body 121 of the positioning portion 12 to be positioned, but in practical applications, the positioning portion can also be integrated by riveting, welding or screwing, however, there are many ways to combine the sleeve 1 with the external plate 4, so that the simple modification and equivalent structural changes made by applying the contents of the description and drawings of the present invention are all included in the scope of the present invention and are well-known.
After the fixing element 3 is locked and fixed on the external plate 5, when the fixing element 3 is vibrated or shaken to release (i.e. rotate counterclockwise), the abutting block 34 of the fixing element 3 is abutted by the first end surface 22 of the damping member 2 to form abutting resistance, and the damping member 2 is elastically supported in the accommodating groove 11 of the sleeve 1 to form elastic resistance, and the damping member 2 rotates in the accommodating groove 11, so that the frictional resistance between the outer side surface of the damping member 2 and the inner side surface of the accommodating groove 11 must be overcome, so that the fixing element 3 is not loosened when influenced and limited by the abutting, elastic and frictional resistance, and the fixing element 3 is stably locked on the external plate 5, thereby achieving the effect of preventing loosening.
When the fixing element 3 is to be separated from the external plate 5, acting forces larger than the resisting, elastic and frictional resistance of the damping member 2 are applied reversely by a bare hand or a hand tool, so that the head 31 of the fixing element 3 rotates reversely (counterclockwise), and the fixing element 3 performs a releasing action, and further the locking part 33 of the fixing element 3 can be withdrawn from the positioning hole 51 of the external plate 5, and in the withdrawing process of the fixing element 3, the resisting block 34 of the fixing element 3 is resisted by the first end surface 22 of the damping member 2, and the first end surface 22 of the damping member 2 slides along the inclined guide surface 341 of the resisting block 34, so that the resisting block 34 can be used to expand the first end surface 22 of the damping member 2 outwards, and further the resisting block 34 extends into the inner side of the sheet body 21 of the damping member 2 and rotates along the inner wall surface of the sheet body 21, so that the reverse rotation action can be performed smoothly, and after the reverse rotation is repeated, the fixing element 3 can be completely separated from the outer plate 5, so as to complete the separation operation.
Furthermore, the above-mentioned abutting block 34 of the fixing element 3 can preferably expand the first end face 22 of the damping element 2 outwards, so that it can extend into the inner side of the sheet body 21 of the damping element 2 and rotate along the inner wall surface of the sheet body 21, so as to perform the releasing action of the reverse rotation, but in practical application, the abutting block 34 of the fixing element 3 can also directly perform the reverse rotation together with the damping element 2, so as to perform the releasing action, thereby separating the fixing element 3 from the external plate body 5.
The invention has the following advantages:
when the fixing element 3 is in a releasing action such as vibration or shaking, the abutting block 34 of the fixing element 3 is abutted by the first end surface 22 of the damping member 2 to form a resistance, so that the resistance of the releasing action is improved by the structural design of the first end surface 22 of the damping member 2 and the abutting block 34 of the fixing element 3, and the fixing element 3 is stably locked on the external plate 5, thereby preventing the fixing element 3 from loosening.
Secondly, when the fixing element 3 is locked, the fixing element 3 rotates along the inner wall surface of the sheet body 21 of the damping element 2, and the second end surface 23 of the damping element 2 does not block the abutting block 34 of the fixing element 3, so that the fixing element 3 can smoothly lock, and the fixing element 3 can smoothly rotate when locked, and can be limited by resistance when released, thereby providing different operation handfeel, and effectively knowing the locking or releasing action.
Third, the damping member 2 is movably installed in the accommodating groove 11 of the sleeve 1, and the first end surface 22 of the damping member 2 can be elastically expanded outward, so that the fixing member 3 can be operated by bare hands no matter locking or releasing actions are performed, and no additional hand tool is needed, thereby enabling the assembling and disassembling process to be more intuitive and rapid, and thus achieving the effect of improving the operation convenience.
Fourthly, a guiding inclined plane 341 is disposed on a side surface of the abutting block 34 of the fixing element 3 adjacent to the first end surface 22, and when the first end surface 22 of the damping member 2 abuts against the guiding inclined plane 341, the abutting block 34 can improve fluency during releasing action by virtue of the guiding inclined plane 341, so as to achieve an effect of optimizing operation hand feeling.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
