Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing:

[0012] See accompanying drawings 1 and 2, the present invention mainly comprises a shock absorber rod 10, a shock absorber tube 20, a shock absorber spring 30 and a clip nut 40.

[0013] One end of the shock-absorbing rod 10 is shaped as an adapter 11 for connecting the corresponding rod body. The other end of the shock-absorbing rod 10 leads to a mandrel 13, and the extended end of the mandrel 13 is provided with an external thread. A shaft shoulder 12 is arranged between. The corresponding rod body is connected by the connecting head 11, so that the shock absorber rod 10 and the rod body are connected as a whole. In this embodiment, the connecting head 11 is a shaft segment type, and its surface is provided with lines that can strengthen the connection. When assembling, the connecting head 11 is coaxial Insert it into the body of the rod (as shown in Figure 3). The axia...

Abstract

The invention relates to the damper technical field, in particular to a damper applicable for alpenstocks, crabsticks, crutches, etc, which comprises an antishock pole, an antishock tube and an antishock spring; one end of the antishock pole is molded into an adaptor for connecting a corresponding pole body; a mandrel is conducted out from the other end of the antishock pole; an extended end of the mandrel is provided with outside threads; a shaft shoulder is arranged between the mandrel and the adaptor; an inner middle section of an inner middle hole of the antishock tube is provided with steps; the mandrel and the shaft shoulder of the antishock pole are sleeved in the inner middle hole of the antishock pole; a nut is in screwed connection with the outside threads of the extended end of the mandrel and in clip connected with the steps; the antishock spring is movably sleeved on the mandrel, embedded in the inner middle hole of the antishock tube and positioned between the shaft shoulder of the antishock pole and the steps of the antishock tube to form the propping antishock pole and the antishock tube. The damper has a simple structure, convenient processing, good intensity, easy assembly and disassembly and convenient maintenance and keeping.

Description

Technical field: [0001] The invention relates to the technical field of shock absorbers, in particular to shock absorbers applicable to trekking poles, canes, crutches and other sticks. Background technique: [0002] Trekking poles, canes, crutches and other sticks can assist the body to support the body, maintain body balance, and provide forward mobility when in use. In order to prevent and reduce the vibration generated when trekking sticks and crutches are used, shock absorbers are generally combined with trekking sticks and crutches. The pole passes over the hand for added safety and comfort. However, the existing shock-absorbing devices used on trekking poles and crutches have the following defects: poor structure, poor assembly stability between components, prone to failures and resulting in failure to shock-absorb and lose their due efficacy. Invention content: [0003] The object of the present invention is to provide a shock absorber that is easy to assemble, h...
