Detailed Description
The present invention is specifically described below by way of exemplary embodiments. It should be understood, however, that elements, structures and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.
In the description of the present invention, it should be noted that the forward direction of the ratchet 3 is the same circumferential direction as the inward and outward bending direction of the ratchet teeth of the ratchet 3, and the reverse direction of the ratchet 3 is the opposite circumferential direction to the inward and outward bending direction of the ratchet teeth of the ratchet 3; the terms "inner", "outer", "upper", "lower", and the like, indicate orientations or positional relationships based on the positional relationships shown in fig. 1, and are merely for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
In one aspect, as shown in fig. 1-3, an embodiment of the present invention relates to an arm-force frame starting position adjusting device, which includes a ratchet 3, an elastic bolt 6, a brake handle 4 and a brake cable 5; the ratchet wheel 3 is fixedly arranged on the periphery of the rotating shaft 2 for rotatably connecting the arm force frame 1, and when the initial position is adjusted, the arm force frame 1 rotates around the rotating shaft 2; the elastic bolt 6 is arranged at the position, close to the rotating shaft 2, of the arm force frame 1, the elastic bolt 6 comprises a pin rod 61, the pin head end of the pin rod 61 is inserted into a tooth groove of the ratchet wheel 3 to be matched with the ratchet wheel 3 to form a ratchet wheel mechanism, and the elastic bolt 6 further comprises an elastic piece 63 used for pushing the pin rod 61 towards the direction close to the ratchet wheel 3 so that the pin head end is in contact with the ratchet wheel 3; the brake handle 4 is arranged at the position for holding the arm force frame 1; one end of the brake cable 5 is connected to the brake handle 4, and the other end is connected to one end of the pin rod 61 away from the ratchet wheel 3, so that the brake cable 5 is driven by the brake handle 4 to pull the pin rod 61 to move away from the ratchet wheel 3. It should be noted that the position for holding of the arm strength frame 1 refers to a position where a trainer can hold the arm strength frame 1 with a hand when using the arm strength frame 1 for training, and in this embodiment, the position for holding of the arm strength frame 1 is specifically a handle arranged at the upper part of the arm strength frame 1; it can be understood that, for the arm force frames 1 with different structures, the positions for holding the arm force frames 1 can be set according to the specific positions for holding the arm force frames 1 by hands of the trainers.
The working principle of the arm force frame initial position adjusting device is as follows: when the initial position of the arm power frame 1 is adjusted along the positive direction of the ratchet wheel 3, a trainer only needs to use the arm to drive the arm power frame 1 to rotate around the rotating shaft 2 along the positive direction of the ratchet wheel 3, and as the pin head end of the pin rod 61 of the elastic bolt 6 is matched with the ratchet wheel 3 to form a ratchet wheel mechanism, when the arm power frame 1 rotates, the pin rod 61 can overcome the elastic force action of the elastic piece 63 to move, so that the pin head end of the pin rod 61 is separated from the current tooth socket and sequentially enters the next tooth socket along the positive direction of the ratchet wheel 3, and the adjustment of the initial position is realized; when the initial position of the arm power frame 1 is adjusted along the reverse direction of the ratchet wheel 3, a trainer holds a brake handle 4 arranged on the arm power frame 1, the brake handle 4 drives a brake wire 5 to pull a pin rod 61 of an elastic bolt 6 to move towards the direction far away from the ratchet wheel 3 by overcoming the elastic force action of an elastic piece 63, so that the self-locking of the pin end of the pin rod 61 and the ratchet wheel 3 is released, the trainer drives the arm power frame 1 to rotate around a rotating shaft 2 along the reverse direction of the ratchet wheel 3 by using the arm, the adjustment of the initial position can be realized, and the pin end of the pin rod 61 and the ratchet wheel 3 can be locked by loosening the brake handle 4 after the adjustment is in place; in the process of adjusting the initial position of the arm power frame 1, the arm of the trainer does not leave the arm power frame 1, so that whether the adjusted position is suitable or not can be sensed in real time.
Above-mentioned arm strength frame initial position adjusting device, when adjusting 1 initial position of arm strength frame, training personnel's arm need not to leave arm strength frame 1, can make training personnel feel in real time at the in-process of adjusting 1 initial position of arm strength frame whether the position after the regulation is suitable, the simple operation, it is efficient to adjust. In addition, in the arm power frame starting position adjusting device, the brake handle 4 is arranged at the holding position of the arm power frame 1, so that the device accords with ergonomics and has better user experience.
Further, as shown in fig. 2 and 3, the elastic latch 6 further includes a guide groove 62 for limiting the moving direction of the pin 61, the guide groove 62 is fixedly installed on the arm frame 1, the guide groove 62 extends in the radial direction of the ratchet 3, and the pin 61 is inserted into the guide groove 62 and moves relative to the guide groove 62 in the extending direction of the guide groove 62. Through the guide groove 62, the pin rod 61 can only do reciprocating motion close to and far away from the ratchet wheel 3 along the radial direction of the ratchet wheel 3, and the stability of transmission matching of the ratchet wheel mechanism formed by the pin rod 61 and the ratchet wheel 3 is favorably ensured.
Preferably, in order to further improve the stability of the driving fit of the ratchet mechanism formed by the pin rod 61 and the ratchet wheel 3, as shown in fig. 3, the pin head end of the pin rod 61 is in a tooth shape engaged with the ratchet teeth of the ratchet wheel 3.
Further, as shown in fig. 3, in the present embodiment, the elastic member 63 is a spring, the spring is sleeved outside the brake cable 5, and the spring and the pin 61 are coaxially disposed, one end of the spring is fixed to the arm frame 1, and the other end of the spring abuts against one end of the pin 61 away from the ratchet 3. It will be appreciated that other resilient members 63 may be used by those skilled in the art, as long as they urge the pin 61 in a direction approaching the ratchet 3.
In addition, in order to improve the aesthetic appearance, it is preferable that the brake cable 5 is inserted into the arm frame 1 as shown in fig. 1.
On the other hand, as shown in fig. 4, the embodiment of the present invention further provides a butterfly type pectoral training machine, which includes arm frame 1, and arm frame initial position adjusting device is installed on arm frame 1.
