Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

An intelligent chest expander 100 for exercise according to an embodiment of the present invention is described below with reference to fig. 1 to 11, including a bungee cord 10, a fixed pulley assembly 30 and an adjuster 40.

The bungee cord 10 is elastic such that the bungee cord 10 is adapted to be stretched or returned to an initial state. The direction of stretch of bungee cord 10 can be changed by the positioning of the fixed pulley assembly 30. Meanwhile, the friction force between the fixed pulley assembly 30 and the elastic rope 10 is low, so that the elastic rope can be conveniently stretched or adjusted, and the service life is prolonged. In addition, the length of the portion of bungee cord 10 can be automatically adjusted by fixed pulley assembly 30, thereby balancing the length of bungee cord 10 on both sides of fixed pulley assembly 30.

For example, as shown in fig. 1, the intelligent chest expander 100 may include a sensor element 20, the sensor element 20 is disposed at one end of the elastic string 10, and the sensor may acquire information related to the user's fitness, such as the degree of muscle stretching of the user, the number of times the user is stretched and the stretching speed of the intelligent chest expander 100. Meanwhile, the sensor can be in communication connection with electronic equipment such as a mobile phone and the like so as to transmit the relevant fitness information to the electronic equipment, and therefore a user can conveniently acquire the relevant fitness information. For example, the fixed pulley assembly 30 and the sensor assembly 20 may be respectively disposed at both ends of the intelligent chest expander 100.

As shown in fig. 3-11, the adjuster 40 includes a housing 41, a winding post 42, and a ratchet assembly 43, the winding post 42 being rotatably disposed within the housing 41, and the bungee cord 10 being windable about the winding post 42.

The ratchet assembly 43 is connected to the housing 41, the ratchet assembly 43 is used for selectively fixing the winding post 42 or releasing the winding post 42 to adjust the length of the intelligent chest expander 100, the other end of the elastic cord 10 penetrates into the housing 41, winds around the winding post 42 and then penetrates out of the housing 41, and the other end of the elastic cord 10 winds around the fixed pulley assembly 30 and then is fixedly connected to the housing 41. It can be understood that the elastic cord 10 between the fixed pulley assembly 30 and the adjuster 40 is two segments, the directions of the two segments of elastic cord 10 are opposite, and the direction from the adjuster 40 to the elastic cord 10 at the other end of the intelligent chest expander 100 is one segment, so that the length of the intelligent chest expander 100 can be changed by adjusting the length of the elastic cord 10 between the fixed pulley assembly 30 and the adjuster 40 or adjusting the length from the adjuster 40 to the other end of the intelligent chest expander 100, and further the length of the intelligent chest expander 100 can be adjusted, and meanwhile, by arranging the ratchet assembly 43, the structure is simple, the length of the intelligent chest expander 100 can be conveniently adjusted, and the stability is good.

According to the utility model discloses intelligence chest expander 100 that body-building was used, intelligence chest expander 100's adjustable length to make intelligence chest expander 100 can adapt to the user of different heights, different demands, improved intelligent chest expander 100's application scope, and intelligence chest expander 100 simple structure, stability is good.

In some embodiments, as shown in fig. 3-10, the ratchet assembly 43 may include a gear 431, a ratchet 432 and a toggle handle 433, the gear 431 is disposed on the post 42, the gear 431 and the post 42 rotate coaxially, the ratchet 432 is engaged with the gear 431, the toggle handle 433 is disposed outside the housing 41 for the user to toggle, and the toggle handle 433 is fixedly connected with the ratchet 432. When the toggle handle 433 is toggled, the toggle handle 433 drives the ratchet 432 to rotate, the ratchet 432 is separated from the gear 431, the winding post 42 can rotate, and the elastic cord 10 can move around the winding post 42 to adjust the distance between one end of the elastic cord 10 and the adjuster 40. Through setting of stirring handle 433, can be convenient for adjust the length of intelligent chest expander 100 with the user, and when need not to adjust, ratchet assembly 43's structural stability is good.

For example, the ratchet 432 and the gear 431 both have a plurality of teeth arranged at intervals, when the toggle handle 433 is in an initial state, at least one tooth of the ratchet 432 abuts between two adjacent teeth of the gear 431, and at least one tooth of the gear 431 abuts between two adjacent teeth of the ratchet 432, so that the ratchet 432 and the gear 431 can be limited to each other, the winding rod cannot rotate as the gear 431 and the winding post 42 rotate coaxially, the toggle handle 433 can separate the gear 431 and the ratchet 432 from each other, so that the winding rod can rotate to realize length adjustment of the intelligent chest expander 100, and stepped adjustment of the intelligent chest expander 100 is realized through arrangement of the gear 431 and the ratchet 432. Of course, in other embodiments, the ratchet-and-ratchet assembly 43 may also have a pawl or the like to achieve stepless adjustment of the ratchet-and-ratchet assembly 43. In the description of the present invention, "a plurality" means two or more.

In some embodiments, the ratchet-and-ratchet assembly 43 further comprises: the reset member 434, the reset member 434 is connected with the ratchet 432 to drive the ratchet 432 to be constantly engaged with the gear 431. Thus, after the user adjusts the length of the intelligent chest expander 100, the user does not need to control the toggle handle 433 to reset, and the operation steps of the user are reduced.
