Abstract
Description
- The present invention relates to a shock absorber, and more particularly to a shock absorber which is anti-detachment.
- A conventional shock absorber for a vehicle as disclosed in TWM392765 includes a base, a fixed axial tube and a movable axial tube. The fixed axial tube is screwed with the base, the movable axial tube is disposed in the fixed axial tube and reciprocatable along an axial direction, and through the fixed axial tube and the base rotate relative to each other, a length of the shock absorber can be adjusted in accordance with different types of vehicles. To prevent the fixed axial tube from rotating too much and being detached from the base, a lower position-restricting ring of the conventional shock absorber which is screwed with the fixed axial tube has a through hole, a ball member, an elastic member and a fixing pin member are disposed in the through hole, and a lower end of the fixed axial tube has an annular groove. Therefore, when the fixed axial tube is rotated to make the ball member restrictably engaged within the annular groove, a user can be reminded that if s/he continues to rotate the fixed axial tube, the fixed axial tube will be detached from the base.
- However, in the conventional shock absorber, the lower position-restricting ring is screwed with the fixed axial tube, so the user needs to grip on the fixed axial tube with one hand and grips on the lower position-restricting ring with the other hand so as to position the lower position-restricting ring on an end of the base to prevent the lower position-restricting ring and the fixed axial tube from moving relative to each other. Hence, the conventional shock absorber is inconvenient to be operated. In addition, the lower position-restricting ring is screwed with the fixed axial tube but not integrally connected to the base, so a distance between the lower position-restricting ring and the base may vary. The ball member being restrictably engaged in the annular groove does not mean that the fixed axial tube is about to be detached from the base, so a reminding function may have an error.
- The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
- The major object of the present invention is to provide a shock absorber, the shock absorber includes an abutting assembly which can effectively remind a user that a first axial tube is about to be detached from a base. In addition, the abutting assembly is easy to be assembled or disassembled and has a simple structure.
- To achieve the above and other objects, a shock absorber is provided, including a base, a first axial tube, a second axial tube, a buffering structure and an abutting assembly. The base defines an axial direction, and the base has a through hole radially. An exterior circumferential wall of the first axial tube has a recess formed radially and near a first end of the base, and the first axial tube is screwed with the base. The second axial tube is disposed through the first axial tube along the axial direction and slidable relative to the first axial tube, and the second axial tube has an assembling portion. The buffering structure includes an elastic member and an adjusting ring, the adjusting ring is sleeved on the first axial tube and movable relative to the first axial tube, and the elastic member abuts against and between the assembling portion and the adjusting ring. The abutting assembly includes an abutting member and an elastic abutting member, the abutting member is disposed within the through hole, the elastic abutting member is disposed on the base and at least partly located in the through hole so as to abut the abutting member to move toward the base normally. When the first axial tube rotates relative to the base and the abutting member corresponds to the recess, the abutting member is restrictably engaged within the recess.

axial tube 2 rotates relative to thebase 1, and theabutting member 51 corresponds to therecess 21, theabutting member 51 is restrictably engaged within therecess 21. When the abuttingmember 51 abuts against a wall of therecess 21, theabutting member 51 clanks (as shown inFIG. 7 ) so as to inform the user than if s/he continues to rotate the firstaxial tube 2 to move away from thebase 1, the firstaxial tube 2 will be detached from thebase 1. - Specifically, in this embodiment, the elastic abutting
member 52 is an elasticannular piece 522, and the elastic abuttingmember 52 is detachably arranged on an exterior circumferential wall of thebase 1 so as to abut the abuttingmember 51 to move toward thebase 1 normally. - Preferably, the shock absorber further includes a position-restricting

FIGS. 8 to 10 for a second embodiment of the present invention. An elastic abuttingmember 52A includes aspring 523 and apin member 524, thepin member 524 is hollow and tubular and disposed in the through hole, thespring 523 and the abuttingmember 51 are located in thepin member 524, and thespring 523 elastically abuts against and between thepin member 524 and the abuttingmember 51 so as to abut the abuttingmember 51 to move toward thebase 1. Specifically, in this embodiment, thepin member 524 is screwed within the through hole (in other embodiments, thepin member 524 may be tightly fit into the through hole) so to be easily disassembled. Through thepin member 524 being engaged within the through hole and thespring 523 abutting the abuttingmember 51 to move toward thebase 1, the abuttingmember 51 can effectively abut against therecess 21 so as to remind the user that the firstaxial tube 2 is about to be detached from thebase 1. - Given the above, in the shock absorber, it is convenient to assemble/disassemble the abutting member and the elastic abutting member, and when the abutting member abuts against the wall of the recess, the abutting member clanks so as to inform the user that if s/he continues to rotate the first axial tube to move away from the base, the first axial tube will be detached from the base.
- While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
