Description

Technical Field

[0001] The invention relates to a treadmill, in particular to a flexible treadmill platform. Background Art

[0002] At present, the shock absorption of treadmill platforms is mainly achieved by setting springs at the bottom of the running board. The limitation of setting springs is that they are set locally, the force is unbalanced, the elasticity and shock absorption effects are poor, and noise will be generated after long-term use. Therefore, the development of a new type of flexible treadmill platform has become an urgent problem to be solved by technical personnel in this field. Summary of the invention

[0003] The present invention is to solve the above-mentioned shortcomings and provides a flexible treadmill platform.

[0004] The above-mentioned purpose of the present invention is achieved through the following technical solutions: a treadmill flexible running platform, including a base frame, a running board and a running belt, the running board is fixed on the base frame at both sides, the running belt is annular, and the front and rear ends are respectively sleeved on the motor roller and the driven roller on the front and rear sides of the running board, the running board is located in the running belt, and the running board extends outwardly from the upper side bar fixing part toward the opening direction on both sides of the running belt, and is connected with the upper side bar; the bottom of the upper side bar is provided with a fixing groove penetrating the front and rear ends, and the upper side bar is provided with a round steel through hole penetrating the front and rear ends, and the upper side bar is fixed to the upper side bar fixing parts on both sides of the running board by a screw and nut assembly; the round steel through hole of the upper side bar is penetrated with a spring round steel.

[0005] Furthermore, there is at least one round steel through hole, and a corresponding number of spring round steels are passed through it.

[0006] Furthermore, the screw and nut assembly includes a square head screw, a flat gasket and a lock nut, the upper end of the square head screw is clamped in the fixed slot at the bottom of the upper side strip, the lower end of the square head screw passes through the running board, and is locked by the flat gasket and the lock nut.

[0007] Furthermore, elastic pads are provided between the bottom of both sides of the running board and the base frame, the lower ends of the elastic pads are provided with screw parts connected as one body and connected to the base frame, the upper ends of the elastic pads are provided with screw holes and connected to the running board through screws.

[0008] Furthermore, the upper edge strip is an aluminum profile.

[0009] Compared with the prior art, the advantages of the present invention are as follows: the present invention inserts the spring round steel into the round steel through hole of the upper side bar, so that the spring round steel and the upper side bar become a whole, and then fixes them on the running board, so that the upper side bar, the spring round steel and the running board become a whole. During use, the running board is bent and deformed downward due to the influence of the mass of the human body. At this time, the spring round steel rebounds under the force and rebounds together with the running board, thereby achieving the purpose of shock absorption and buffering, reducing the impact force of the user when running; moreover, the force is balanced and the shock absorption effect is good.

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0017] like Figures 1 to 6 As shown, a treadmill flexible running platform includes a base frame 1, a running board 2 and a running belt 3, wherein the running board 2 is fixed on the base frame 1 at both sides, the running belt 3 is annular, and is respectively sleeved on the motor roller 4 and the driven roller 5 on the front and rear sides of the running board 2 at the front and rear sides, the running board 2 is located in the running belt 3, and the running board 2 extends an upper side bar fixing part 2-1 outwardly toward the opening direction on both sides of the running belt 3, and is connected with an upper side bar 6; a fixing groove 6-1 penetrating through the front and rear ends is provided at the bottom of the upper side bar 6, and a round steel through hole 6-2 penetrating through the front and rear ends is provided in the upper side bar 6, and the upper side bar 6 is fixed to the upper side bar fixing parts 2-1 on both sides of the running board 2 by a screw and nut assembly 7; a spring round steel 8 is penetrated through the round steel through hole of the upper side bar 6.

[0018] Furthermore, there is at least one round steel through hole 6 - 2 , and a corresponding number of spring round steels 8 are passed through it.

[0019] Furthermore, the screw-nut assembly 7 includes a square head screw 7-1, a flat gasket 7-2 and a lock nut 7-3, the upper end of the square head screw 7-1 is clamped in the fixed slot 6-1 at the bottom of the upper side strip 6, the lower end of the square head screw 7-1 passes through the running board 2, and is locked by the flat gasket 7-2 and the lock nut 7-3.
