Sliding machine

Abstract

A sliding machine comprising a base and a guide rail arranged on the base, wherein a pedal assembly is arranged on the guide rail, which is slidably connected to the guide rail, and slides along the guide rail. The present invention adopts a special connection method between the elastic assembly and the pedal assembly, that is, one end of the elastic member is set on the base, and the other end is set on the pedal assembly through a connecting shaft, and the axial position of the connecting shaft is positioned by the frictional force between the connecting shaft and the pedal assembly. This design greatly simplifies the structure of the sliding machine. Compared to traditional sliding machines that use complex connection frames at the connection between the elastic device and the pedal, this design reduces the number and complexity of components, thereby lowering manufacturing costs.

What is claimed is: 
     
         1 . A sliding machine, comprising a base and a guide rail set on the base, wherein a pedal assembly is set on the guide rail, the pedal assembly is slidably connected to the guide rail, and the pedal assembly is configured to slide along the guide rail;
 an elastic assembly is configured between the pedal assembly and the base for providing damping force to the pedal assembly, the elastic assembly includes an elastic member, one end of which is set on the base, the elastic assembly also includes a connecting shaft, and the other end of the elastic member is set on the pedal assembly through the connecting shaft, the elastic member uses a frictional force between the connecting shaft and the pedal assembly, by tightening the connecting shaft, to position an axial position of the connecting shaft.   
     
     
         2 . The sliding machine according to  claim 1 , wherein the pedal assembly is provided with an installation groove for setting the connecting shaft, and the shape of the installation groove is U-shaped. 
     
     
         3 . The sliding machine according to  claim 2 , wherein a lower side of the pedal assembly is provided with at least a rib plate for improving a strength of the pedal assembly, and the installation groove is provided on the rib plate. 
     
     
         4 . The sliding machine according to  claim 1 , wherein the elastic assembly further comprises a shaft body, and the elastic member is set on the base through the shaft body. 
     
     
         5 . The sliding machine according to  claim 4 , wherein the elastic member is an elastic ring, which is formed by surrounding an elastic rope, one end of the elastic ring is wound around the connecting shaft, and the other end of the elastic ring is wound around the shaft body. 
     
     
         6 . The sliding machine according to  claim 1 , wherein there are two elastic assemblies, and the two elastic assemblies are respectively set at both ends of the pedal assembly. 
     
     
         7 . The sliding machine according to  claim 6 , wherein two elastic assemblies are respectively set at left and right ends of the pedal assembly. 
     
     
         8 . The sliding machine according to  claim 1 , there are two guide rails, and the elastic assembly is located between the two guide rails. 
     
     
         9 . The sliding machine according to  claim 8 , wherein the two guide rails are respectively located on front and rear sides of the pedal assembly. 
     
     
         10 . The sliding machine according to  claim 8 , wherein the guide rails are welded to the base.
