Abstract

An electric speed-limiting treadmill, comprising a base, a handrail, and a running belt. The running belt is sleeved on a driven roller and a driving roller to form a belt transmission mechanism. The two axial ends of the driven roller are each provided with a speed reducer. Wheel, the speed of the treadmill is limited by the cooperation of the stopper arranged on the deceleration wheel and the anti-skid cylinder. In the present invention, the protection pads arranged under the armrests can reduce injuries from falls, and the pain can be relieved by the cushioning of falling on the protection pads. At the same time, a deceleration belt is arranged at the rear of the treadmill. If you fall, you can step into the deceleration belt in time to slow down the human body from sliding backwards. , to reduce the friction between the human body and the equipment and the ground, so as to avoid scratches. At the same time, a block and an anti-skid cylinder are set on the driven roller, and the block is contracted in the reduction wheel through the spring. When the speed is too fast, The centrifugal force received by 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 excessive speed.

Description

An electric speed-limiting treadmill

technical field

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

Background technique

Treadmill is a kind of commonly used fitness equipment, which can be used to warm up the human body, and can also allow users to exercise. Without safety guidance, users often encounter exercisers who accidentally fall down and injure their arms while running. At the same time, they will row backwards along the treadmill. At the same time, sometimes the treadmill will overspeed and cause accidents.

Contents of the invention

The purpose of the present invention is to provide an electric speed-limited treadmill to solve the problem that existing treadmills are prone to overspeeding and cause accidents. In the present invention, a stopper and an anti-skid cylinder are arranged on the driven roller, and the stopper is contracted by a spring. 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, then 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 electric speed-limiting treadmill, comprising a base, a handrail and a running belt, the handrail is arranged on one end of the base, the running belt is installed on the base, and the running belt is driven by the cooperation of the driven roller and the driving roller fixed on the base The running belt is set on the driven roller and the driving roller to form a belt transmission mechanism. The driving roller is connected to the motor, and the shaft end of the driving roller is connected to the output end of the motor through a coupling. The two ends of the roller and the driving roller are connected to the side wall of the base through bearings, and are sealed by the end cover arranged on the side wall. There is a movable cover on the upper surface of the base near the two ends of the running belt, and the movable cover is just right. The cover is arranged on the holes on both sides of the running belt. A connecting plate I is connected to the bottom of the movable cover plate. An anti-skid cylinder is installed on the connecting plate I. A speed reduction wheel is respectively arranged at both ends of the axial direction of the driven roller. There is a groove in the diameter direction of the reduction wheel, and a spring with pre-tightening force is arranged in the groove. One end of the spring is fixed in the groove, and a stopper is connected to the other end. The stopper shrinks in the groove through the pre-tightening force of the spring. Inside, when the stopper is in the vertical position, the projection on the movable cover is just in the anti-skid tube, and the speed of the treadmill is limited by the cooperation of the stopper and the anti-skid tube.

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 the distance that the stopper protrudes will change after the distance is changed, thereby changing the centrifugal force and making the driven The speed of the rollers is changed online.

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

The beneficial effect of the present invention is that: the present invention can reduce falls through the protective pads arranged under the armrests, relieve pain through the cushioning of the protective pads when falling, and at the same time, a deceleration belt is arranged at the rear of the treadmill, so that if you fall down, you can step into it in time The deceleration belt slows down the human body to slide backwards, reducing the friction between the human body and the equipment and the ground, thereby avoiding scratches. At the same time, a stopper and an anti-skid cylinder are set on the driven roller, and the stopper is shrunk in the deceleration wheel through a spring. , when the speed is too fast, the centrifugal force on the stopper is greater than the pre-tightening force of the spring, then 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.

Detailed ways

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

An electric speed-limiting treadmill, comprising a base 1, an armrest 2 and a running belt 4, the armrest 2 is arranged on one end of the base 1, the running belt 4 is installed on the base 1, and passes through driven rollers fixed on the base 1 7 and the driving roller 6 cooperate to drive the running belt 4 to rotate, and the running belt 4 is set on the driven roller 7 and the driving roller 6 to form a belt transmission mechanism. The driving roller 6 is connected with the motor 9, and the driving roller The shaft end of 6 is connected to the output end of the motor 9 through a coupling 10, and both ends of the driven roller 7 and the driving roller 6 are connected to the side wall of the base 1 through the bearing 12, and the end cover arranged on the side wall Sealing, the upper surface of the base 1 near the two ends of the running belt 4 is respectively provided with a movable cover 8, the movable cover 6 just covers the holes on both sides of the running belt 4, and a connecting plate I801 is connected below the movable cover 8 , an anti-skid cylinder 13 is installed on the connecting plate I801, and a speed reduction wheel 11 is respectively arranged at both ends of the driven roller 7 in the axial direction.
