The utility model belongs to body -building equipment technical field, especially relates to a spring frame subassembly for body -building equipment, including frame body, a plurality of elastic tension members are connected on the frame body, one end of elastic tension member is connected in the downside of frame body, and the other end is detachably connected in the upside of frame body, a plurality of tension member limiting grooves are equipped on the frame body, tension member limiting groove and elastic tension member are set up one by one, and tension member limiting groove is used for the limiting of elastic tension member, the utility model provides a spring frame subassembly for body -building equipment, sets up limiting rotation wheel, and the elastic tension member is limited through the tension member limiting groove on it, can effectively avoid the collision between elastic tension member in the stretching process, reduces the noise, and the fluency improves.

The utility model relates to unload grain machine technical field discloses a kind of unload grain machine with buffer shock-absorbing function, including horizontal support frame, the left side of the horizontal support frame is fixedly connected with inclined support frame, the front end of the inclined support frame is provided with control box.The unload grain machine with buffer shock-absorbing function is provided with hopper, spring frame, buffer spring and damper, when the grain conveyed falls to the inside of hopper, buffer spring can buffer hopper by the elasticity of itself, buffer hopper can effectively reduce the impact force of grain when falling, avoid grain to break or be damaged due to impact, damper in buffer spring can limit buffer spring, prevent the amplitude of hopper to be too large, the connecting plate of support block top end can slide up and down in the inside of spring frame, so that buffer spring and spring frame can be further limited, solve the problem that grain has greater impact force when falling, grain is easily broken or damaged due to impact.
