Abstract

A dumbbell with a counting function is characterized in that a beating counting device consisting of a pawl device, a ratchet wheel, a carry gear and a pendulum bob is arranged on the side face of a dumbbell cake, the pawl device is formed by assembling four parts, namely a pawl arm, a pawl reset torsion spring, a pawl finger and a pin, and the pawl device is assembled on the side face of the dumbbell cake through the pawl arm reset torsion spring. Through pendulum hammer beat pawl device, pawl device promotes ratchet, ratchet and drives carry gear again and realizes automatic count and carry function. The invention can realize automatic counting in the exercise activity of the exerciser using the dumbbell, and is convenient and novel.

Description

Dumbbell with counting function

Technical Field

The invention relates to a dumbbell with a counting function, wherein a beating counting device is arranged in the side surface of the dumbbell, the dumbbell is lifted and put down once, a pendulum hammer in the beating counting device can beat a counting pawl once, and the pawl pushes a ratchet wheel to rotate a tooth to realize the counting function. The method relates to the technical field of mechanical design and the like.

Background

The dumbbell is a common fitness device, but the common dumbbell cannot realize automatic counting when grabbing and lifting fitness, which brings certain inconvenience to people who plan to build fitness everyday.

Disclosure of Invention

In order to overcome the defects of the traditional dumbbell, the invention discloses a counting device with a beating device arranged in the side surface, the dumbbell is lifted and put down once, a counting pawl can be beaten once by beating a pendulum in the counting device, and the pawl pushes a ratchet wheel to rotate a tooth to realize the counting function.

The technical scheme of the invention is as follows: a dumbbell with a counting function is characterized in that a beating counting device which is composed of a pawl device (1), a ratchet wheel (2), a carry gear (3) and a pendulum (4) is arranged on the side surface of a dumbbell cake (5); the dumbbell with the counting function is characterized in that the pawl device (1) is formed by assembling four parts, namely a pawl arm (1-1), a pawl reset torsion spring (1-2), a pawl finger (1-3) and a pin (1-4), the pawl device (1) is assembled on the side face of a dumbbell cake (5) through the pawl arm reset torsion spring (1-5), the pawl device (1) is beaten through the pendulum bob (4), and the pawl device (1) pushes the ratchet wheel (2) and the ratchet wheel (2) drives the carry gear (3) to achieve automatic counting and carry functions.

The dumbbell has the beneficial effects that the dumbbell can realize automatic counting in the process of using the dumbbell to carry out fitness activities, and is convenient and novel.

Detailed Description

The assembling process comprises the following steps: firstly, assembling a pawl arm (1-1), a pawl reset torsion spring (1-2), a pawl finger (1-3) and a pin (1-4) according to the mode of figures 2 and 3, wherein the assembled effect is shown in figure 4. The detent device (1) and the detent arm reset torsion springs (1-5) which are assembled just now are assembled on the side surface of the dumbbell cake (5) according to the mode of figure 5, and the assembled effect is shown in figure 6. Then, the pawl device (1), the ratchet wheel (2), the carry gear (3) and the pendulum bob (4) are assembled on the side surface of the dumbbell cake (5) according to the mode of fig. 7, and the assembled effect picture is shown in fig. 8. Finally, the end cover (6) is assembled on the side surface of the bell cake (5), and the device is completely assembled.

The working principle is as follows: when an exerciser uses the dumbbell to do a lifting exercise, the dumbbell will generally pause in two positions, dumbbell high (a) and dumbbell low (B) in fig. 10. Because the hand of a person grips the dumbbell tightly, the positions of the bell cake (5), the hand and the small arms are kept unchanged in the whole movement, and the small arms of the person form an included angle of about 90 degrees with each other in the two positions of the dumbbell high position (A) and the dumbbell low position (B), so that the whole dumbbell also rotates about 90 degrees in the two positions, but the pendulum bob (4) is always kept in a vertical state due to the action of gravity. Therefore, the dumbbell is not lifted once, the pendulum bob (4) impacts the primary pawl device (1), and the pawl device (1) pushes the ratchet wheel (2) to rotate one tooth, so that the counting function is realized. And the ratchet wheel (2) pushes the carry gear (3) to rotate a number through the gear meshing relationship every time the ratchet wheel rotates one circle, so that carry is realized. The resetting and the zeroing of the device can be realized only by screwing the protruding part of the rotating shaft of the ratchet wheel (2) or the carry gear (3) by hands.
