Novel test fixture for prosthesis shock absorber

Technical Field

The utility model relates to the technical field of bicycle testing equipment, in particular to a novel test fixture for a prosthesis shock absorber.

Background

In the daily laboratory test process of bicycles, a type of full shock absorber vehicle type needs to be provided with a shock absorber during the test. With real shock absorber, damage is very easy during testing, and the cost is very high. In addition, the prosthesis shock absorber is installed, is made of steel, is generally of a fixed size, and cannot adjust the total length of the prosthesis shock absorber and the relative angles of hole sites of the assembly areas at the two ends. Because different models have different requirements on the total length of the prosthesis shock absorber and the relative angles of hole sites of assembly areas at two ends during testing, and the same model also has different requirements on the total length of the prosthesis shock absorber during testing different projects, a large number of prosthesis shock absorbers are required to be prepared for testing, the cost is high, the replacement and clamping time is long, and the efficiency is low.

Therefore, the application designs a novel test fixture for the prosthesis shock absorber so as to solve the problems.
