Description

An outdoor speed-limiting mechanical treadmill

technical field

The invention relates to an auxiliary equipment for physical exercise, in particular to an outdoor speed-limiting mechanical treadmill.

Background technique

Treadmill is a commonly used fitness equipment, which can be used to warm up the human body and allow users to exercise. Outdoor mechanical treadmills are generally used in parks to facilitate the exercise of surrounding residents. However, due to lack of Safety guidance often encounters exercisers who accidentally fall down while running and easily break their arms. At the same time, they will row backwards along the treadmill. At the same time, sometimes children often make the treadmill overspeed and cause accidents.

Contents of the invention

The purpose of the present invention is to provide an outdoor speed-limiting mechanical treadmill to solve the problem that existing treadmills are prone to overspeed and cause accidents. The present invention is provided with a stopper and an anti-skid cylinder, and the spring makes the stopper contract in the deceleration wheel. When the speed is too fast, the centrifugal force on the block is greater than the pre-tightening force of the spring, so the spring will pop out and be inserted into the anti-skid tube to slow down the speed and avoid accidents caused by too fast speed.

The present invention is for solving the deficiencies of the above-mentioned technical problems, and the technical scheme adopted is:

An outdoor speed-limiting mechanical treadmill, comprising a base, a handrail and running rollers, the handrail is arranged at one end of the base, the two ends of the running roller are rotationally connected to the side wall of the base, and the two ends of the running roller are connected to the side wall of the base through bearings, And it is sealed by the end cover arranged on the side wall. A movable cover is arranged on the upper surface of the base close to the two ends of the running roller. The movable cover just covers the holes on both sides of the running roller. A connection plate I is connected, and an anti-skid cylinder is installed on the connection plate I, and a speed reduction wheel is respectively arranged at both ends of the axial direction of the running roller, and a groove is provided in the diameter direction of the speed reduction wheel. The tension spring, one end of the spring is fixed in the groove, and the other end is connected with a stopper, the stopper shrinks in the groove through the pre-tightening force of the spring, the projection of the stopper on the movable cover when the stopper is in the vertical position Just located in the anti-skid cylinder, the speed of the treadmill is limited by the cooperation of the stopper and the anti-skid cylinder.

The anti-skid cylinder includes a cylindrical structure, and the outer bottom of the cylindrical structure is welded with a connecting plate II that cooperates with the connecting plate I, and the connecting plate I and the connecting plate II are connected by bolts, and the connecting plate I is connected to the connecting plate II. Plates II can be adjusted to each other to change the distance between the anti-skid cylinder and the deceleration wheel, thereby changing the upper limit of the speed limit of the treadmill, because after the distance is changed, the distance that the stopper protrudes will change, so that the centrifugal force changes, so that the running roller The speed of the wheel changes on-line.

A handle is provided on the movable cover to facilitate the movement of the movable cover.

The beneficial effects of the present invention are: the present invention is provided with a stopper and an anti-skid cylinder, and the spring makes the stopper contract in the deceleration wheel. When the speed is too fast, the centrifugal force received by the stopper is greater than the preload force of the spring, and the spring It is best to pop out and insert the anti-skid tube to slow down the speed and avoid accidents caused by excessive speed.

detailed description

As shown in the figure, the specific implementation method is as follows:

An outdoor speed-limiting mechanical treadmill, comprising a base 1, an armrest 2, and a running roller 4, the armrest 2 is arranged at one end of the base 1, the two ends of the running roller 4 are rotationally connected with the side wall of the base 1, and the two running rollers 4 The end is connected with the side wall of the base through the bearing 8, and is sealed by the end cover arranged on the side wall. A movable cover 6 is respectively arranged on the upper surface of the base 1 close to the two ends of the running roller 4, and the movable cover 6 is just covered. On the holes on both sides of the running roller, a connecting plate I601 is connected under the movable cover plate 6, and an anti-skid cylinder 9 is installed on the connecting plate I601, and the two axial ends of the running roller 4 are respectively provided with a deceleration The wheel 7 and the deceleration wheel 7 are provided with a groove in the diameter direction, and a spring 11 with a pre-tightening force is arranged in the groove, and one end of the spring 11 is fixed in the groove, and a stopper 10 is connected to the other end, and the stopper 10 passes through the spring The pretightening force of 11 shrinks in the groove, and the projection on movable cover plate 6 when block 10 is positioned at vertical position is just positioned in the anti-skid tube 9, limits treadmill speed by the cooperation of block 10 and anti-skid tube 9.

The anti-skid cylinder 9 includes a cylindrical structure 901, and the outer bottom of the cylindrical structure 901 is welded with a connecting plate II902 that matches the connecting plate I601. The connecting plate I601 and the connecting plate II902 are connected by bolts, and the connecting plate I601 and connecting plate II902 can be mutually adjusted to change the distance between the anti-skid cylinder 9 and the deceleration wheel, thereby changing the speed limit upper limit of the treadmill, because the distance that the stopper 10 protrudes will change after the distance changes, so that the centrifugal force Change, the speed of running roller 4 is changed online.

The movable cover 6 is provided with a handle for moving the movable cover 6 conveniently.

The technical solutions and implementation methods listed in the present invention are not limiting, and solutions that are equivalent to or have the same effect as the technical solutions and implementation methods listed in the present invention are within the protection scope of the present invention.
