Description
Technical field:
The utility model relates to the shock absorber technical field, refers in particular to the shock absorber of cane bars such as can be applicable to alpin-stock, walking stick, crutch.
Background technique:
Cane bars such as alpin-stock, walking stick, crutch play the supplemental support health in use, keep one's balance, and effects such as preceding action edge are provided.For the vibrations that prevent and produced when reducing the use of alpin-stock, crutch, generally on alpin-stock, crutch, be combined with shock absorbing apparatus, the seismic wave that can avoid the end that contacts to earth of alpin-stock, crutch to produce by the shock-absorbing of shock absorbing apparatus passes on hand along the cane bar, improves Security and travelling comfort.Yet there is following defective in the existing shock absorbing apparatus that is used on alpin-stock, the crutch: structural not good, assemble stable is bad between the assembly, easily breaks down and cause can not shock-absorbing, loses its due effect.
Summary of the invention:
The purpose of this utility model is to provide a kind of and is convenient to assembling, and structural good, is fit to the shock absorber that the various bodies of rod use.
For achieving the above object, the utility model adopts following scheme to realize:
Core damper comprises a shock-absorbing bar, a shock-absorbing pipe and a shock-proof spring, and the shock-absorbing bar has an end to be shaped to jointing head, is used to connect the corresponding body of rod, and the other end of shock-absorbing bar is drawn a mandrel, and the mandrel overhanging end is provided with outside thread, and a shaft shoulder is arranged between mandrel and the jointing head; The interior stage casing of mesopore is provided with step within the shock-absorbing pipe, and the mandrel of shock-absorbing bar and the shaft shoulder are arranged in mesopore within the shock-absorbing pipe, the be spirally connected outside thread of mandrel overhanging end of a nut, and form clamping with step; Shock-proof spring pivot bush unit mandrel, and being embedded within the shock-absorbing pipe in the mesopore between the step of the shaft shoulder of shock-absorbing bar and shock-absorbing pipe, forms a top shock-absorbing bar and a shock-absorbing pipe.
Be coaxial configuration between above-mentioned mandrel and the shock-absorbing bar.
Be compared with the prior art, the beneficial effect that the utlity model has is: 1, simple in structure, easy to process, and intensity is good.2, easy accessibility utilizes nut can realize that the shock-absorbing bar is relative with the shock-absorbing pipe and be connected with externally threaded being spirally connected, is beneficial to outside the dismounting, but also convenient for maintaining maintenance, so that increase the service life.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the STRUCTURE DECOMPOSITION schematic representation of Fig. 1;
Accompanying drawing 3 is implemented schematic representation for the utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
See shown in the accompanying drawing 1,2 that the utility model mainly comprises a shock-absorbing bar 10, a shock-absorbing pipe 20, shock-proof spring 30 and a clamping nut 40.
Shock-absorbing bar 10 has an end to be shaped to jointing head 11, is used to connect the corresponding body of rod, and the other end of shock-absorbing bar 10 is drawn a mandrel 13, and mandrel 13 overhanging ends are provided with outside thread, and a shaft shoulder 12 is arranged between mandrel 13 and the jointing head 11.Connect the corresponding body of rod by jointing head 11, make the shock-absorbing bar 10 and the body of rod be connected to an integral body, jointing head 11 is a shaft part formula in the present embodiment, and its appearance is provided with the lines that can strengthen connecting, the jointing head 11 coaxial embedding bodies of rod interior (shown in Figure 3) during assembling.Axially annular groove 12 provides the shock-absorbing space, so that need not establish the shock-absorbing space in addition on the body of rod, also uses with regard to the applicable multiple body of rod thus.
The interior stage casing of mesopore 22 is provided with step 21 within the shock-absorbing pipe 20, and the mandrel 13 of shock-absorbing bar 10 and the shaft shoulder 12 are arranged in mesopore 22 within the shock-absorbing pipe 20; The be spirally connected outside thread of mandrel 13 overhanging ends of nut 40, and form clampings with step 21, thus shock-absorbing pipe 20 and shock-absorbing bar 10 are engaged togather, and prevent separately have position-limiting action.Shock-proof spring 30 pivot bush unit mandrels 13, and being embedded within the shock-absorbing pipe 20 in the mesopore 22 between the step 21 of the shaft shoulder 12 of shock-absorbing bar 10 and shock-absorbing pipe 20, form a top shock-absorbing bar 10 and a shock-absorbing pipe 20.Because the elasticity of shock-proof spring 30 exists, shock-absorbing pipe 20 can be vertically roof pressure shock-proof spring 30 relatively, avoid rigid plugging between shock-absorbing bar 10 and the shock-absorbing pipe 20, promptly have the shock-absorbing effect.
In the present embodiment, be coaxial one processing structure between mandrel 13 and the shock-absorbing bar 10, make things convenient for processing and fabricating, and the machining accuracy height.One port of shock-absorbing pipe 20 has a plug 50 to hide after interlocking nut 40 is finished.
Shown in Figure 3, during use, shock-absorbing bar 10 utilizes jointing head 11 to be fixed on the end of the body of rod, and shock-absorbing pipe 20 combines (being generally the end that contacts to earth) with another body of rod or supporting member, utilize the elastic shock absorbing effect that being flexible coupling between shock-absorbing bar 10 and the shock-absorbing pipe 20 concerns and shock-proof spring 30 provides, make the cane bars such as alpin-stock, walking stick, crutch of this shock absorber that makes up have the shock-absorbing effect, the convenient use, and increase the travelling comfort of using.
