Abstract
The utility model discloses a difference leads to the fact very greatly and obtains data reliable technical problem and provide a saddle fatigue test machine inadequately when solving the saddle fatigue test machine test condition with the in -service use. The utility model discloses the technical scheme who takes is: a saddle fatigue test machine, is including being used for the installation to fix the frame of other part, be used for to support the support component of fixed test saddle, being used for saddle fatigue test's fatigue loading part and being used for carrying out fricative friction part to the saddle simultaneously at the loading. Because the friction part carries out fatigue test at the saddle to rub to the saddle simultaneously for the test condition is close the saddle in -service use condition more, and the test data who consequently obtains science more is reliable.
Description
Technical field
The utility model relates to a kind of fatigue tester, particularly relates to a kind of saddle fatigue tester.
Background technology
Bicycle is modal land cart, although various vehicle technology is flourish in the last few years, bicycle still has the status do not replaced.No matter be traditional pedal type bicycle or electric bicycle, all because easy control easy to learn, light and flexible are extensively liked by people.
In the normal use procedure of bicycle, bicycle saddle can be subject to stampability load and the friction of accumulation property, the ability of the accumulation stampability load that bicycle saddle bears weighs seat security and an important indicator in serviceable life, so saddle must can withstand a certain size fatigability test.Existing saddle fatigue strength test machine only carries out stampability load to saddle, and have ignored friction, and very large with difference in the actual use procedure of bicycle, the data reliability therefore obtained is not strong.
Summary of the invention
The utility model obtains the reliable not technical matters of data for solution saddle fatigue tester test condition and difference during actual use cause very greatly and provides a kind of saddle fatigue tester.
Technical solution adopted in the utility model is: a kind of saddle fatigue tester, comprise the frame for installing fixing miscellaneous part, for support fixing test saddle support component, for saddle testing fatigue fatigue loading parts and for loading simultaneously to the friction means that saddle rubs.Rub to saddle because friction means carries out testing fatigue at saddle, make test condition more close to the actual service condition of saddle, the test data therefore obtained more science is reliable simultaneously.
As preferably, described frame comprises base, the framework of base surrounding and the upper frame of frame roof that lower horizontal is arranged.
As preferably, described support component is erected at top in the middle part of described base.
As preferably, described fatigue loading parts are positioned at above described support component, comprise fixing sleeve on said frame, the pressure rod that can move up and down in sleeve, the pressure head of pressure rod bottom and belt pulley; Described pressure rod top is movably connected in described belt pulley by connecting rod and departs from circle centre position; Described belt pulley is driven by the motor be fixed on described upper frame.Under motor drives, pulley rotation; Drive pressure rod to move up and down in sleeve by connecting rod, provide punching press load to fixing test saddle on the supporting member.
As preferably, described friction means comprises fork and is connected to the friction head of fork lower end; Described fork movable upper end is connected to described pressure rod sidewall part on the lower; Described fork is provided with back-moving spring near between upper end and described pressure rod; When described friction means is not by external force, described friction head is lower than described pressure rod lower end.When pressure rod moves downward, friction head first contacts with saddle upper surface, and along with pressure rod declines further, friction head is in saddle surface sliding friction, and fork is put outward, and back-moving spring is stretched; After pressure rod completes this loading to saddle, pressure rod rises, and spring reset drives fork, friction head to reset.
The advantage that the utility model has and good effect are: because the utility model adopts as above technical scheme, friction means carries out testing fatigue at saddle and rubs to saddle simultaneously, make test condition more close to the actual service condition of saddle, the test data therefore obtained more science is reliable.
Except technical matters, the technical characteristic forming technical scheme and the advantage brought by the technical characteristic of these technical schemes that the utility model described above solves, the advantage that the other technologies feature comprised in the other technologies problem that the utility model can solve, technical scheme and these technical characteristics bring, will be described in further detail hereinafter by reference to the accompanying drawings.

Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As depicted in figs. 1 and 2, the present embodiment is a kind of saddle fatigue tester, comprise the frame for installing fixing miscellaneous part, for support fixing test saddle 3 support component 14, for saddle testing fatigue fatigue loading parts and for loading simultaneously to the friction means that saddle rubs.
Described frame comprises base 1, the framework 2 of base surrounding and the upper frame 8 of frame roof that lower horizontal is arranged.Described support component 14 is erected at top in the middle part of described base 1.Described fatigue loading parts are positioned at above described support component 14, comprise the sleeve 6 be fixed on described framework 2, the pressure rod 5 that can move up and down in sleeve 6, the pressure head 4 of pressure rod 5 bottom and belt pulley 10; Described pressure rod 5 top is movably connected in described belt pulley 10 by connecting rod 7 and departs from circle centre position; Described belt pulley 10 is driven by the motor 9 be fixed on described upper frame 8.Described friction means comprises fork 12 and is connected to the friction head 13 of fork 12 lower end; Described fork 12 movable upper end is connected to described pressure rod 5 sidewall part on the lower; Described fork 12 is provided with back-moving spring 11 near between upper end and described pressure rod 5; When described friction means is not by external force, described friction head 13 is lower than described pressure rod 5 lower end.
Principle of work of the present utility model is: under motor drives, pulley rotation; Drive pressure rod to move up and down in sleeve by connecting rod, provide punching press load to fixing test saddle on the supporting member.When pressure rod moves downward, friction head first contacts with saddle upper surface, and along with pressure rod declines further, friction head is in saddle surface sliding friction, and fork is put outward, and back-moving spring is stretched; After pressure rod completes this loading to saddle, pressure rod rises, and spring reset drives fork, friction head to reset.Rub to saddle because friction means carries out testing fatigue at saddle, make test condition more close to the actual service condition of saddle, the test data therefore obtained more science is reliable simultaneously.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
