a limiting groove 30 is formed in the outer side of the cross rod 15 along the axial direction of the cross rod, a limiting rod 31 is arranged in the limiting groove 30, the limiting rod 31 is hinged with one end, close to the first fixing rod 13, of the limiting groove 30, a hook 32 is formed at the free end of the limiting rod 31, a hanging ring 33 is arranged on the first fixing plate 17, and the hook 32 can be connected to the hanging ring 33 when the extending portion 29 is turned to the vertical position; when the lock head 24 is connected in the lock hole 26, the limiting rod 31 can be horizontally placed in the limiting groove 30, and the end of the limiting rod 31 is attached to the end of the sliding sleeve 12.
The structure design enables the structure of the assistant device to be flexible and changeable, and the assistant device can have multiple functions and shapes and better assist in exercises.
The first fixing lever 13 and the second fixing lever 14 have the same structure, and only the structure of the first fixing lever 13 is described above, and the structure of the second fixing lever 14 is referred to the above description. The first fixing lever 13 has a fixing portion 28 and an extending portion 29 so that the first fixing lever 13 can be turned over in a length direction thereof. The fixing portion 28 is connected to the first fixing plate 17, the first fixing plate 17 and the fixing portion 28 are stationary members in use, and the extending portion 29 and the cross bar 15 connected to the extending portion 29 are reversible. The extending portion 29 can be in a horizontal state (i.e., the extending portion 29 is in the same line with the fixing portion 28) or in a vertical state (i.e., the extending portion 29 is perpendicular to the fixing portion 28).
The limiting groove 30 is formed in the cross rod 15, the limiting rod 31 is arranged in the limiting groove 30, the extending portion 29 can be fixed when being in a vertical state due to the arrangement of the limiting rod 31, and the sliding sleeve 12 can be limited by the limiting rod 31 when the extending portion 29 is in a horizontal state, so that the sliding sleeve 12 cannot move on the cross rod 15. The limiting rod 31 and the limiting groove 30 are hinged, so that the limiting rod 31 can be turned over to the vertical cross rod 15 and can also be connected in the limiting groove 30 (when the limiting rod 31 is connected in the limiting groove 30, only one part of the limiting rod is positioned in the limiting groove 30).
When the extension 29 is turned to the vertical position, the hook 32 at the end of the stopper rod 31 is hooked in the hook 33 of the first fixing plate 17, so that the stopper rod 31 is connected to the first fixing plate 17, and the extension 29 is limited to the vertical state. At this time, the stopper rod 31 is separated from the slide sleeve 12, and after the restriction between the lock lever 23 and the lock hole 26 is released, the slide sleeve 12 can be pushed by the spring 16.
When the extension 29 is turned to the horizontal position, the limiting rod 31 is placed in the limiting groove 30, so that the end of the limiting rod 31 is attached to the end of the sliding sleeve 12, the sliding sleeve 12 is limited by the limiting rod 31, and even if the lock hole 26 is separated from the lock head 24, the sliding sleeve 12 cannot move on the cross rod 15. In this case, the power assistance device can be used as an auxiliary device, so that the swimmer can rest on the crossbar 15 or the sliding sleeve 12 with his hands when swimming to the half position, or can restore the balance by means of the power assistance device when losing balance in the body of water. Alternatively, the cross bar 15 can also be used as a carrying part to enable a person to sit on the cross bar for rest. The limiting function of the limiting rod 31 on the sliding sleeve 12 enables a person to hold the sliding sleeve 12 or sit on the cross rod 15 for rest, even if the pressing block 27 is touched by mistake, the sliding sleeve 12 cannot move on the cross rod 15, and the safety and stability of the human body are ensured.
As shown in fig. 5 and 6, the pressing block 27 is made of rubber, and the middle part of the pressing block 27 protrudes toward the lock hole 26 and is attached to the lock head 24; one surface of the lock head 24 facing the abutting portion 21 is a vertical surface, and the other surface of the lock head 24 is an inclined surface. The rubber pressing block 27 enables the sliding sleeve to have flexibility and rigidity, and the locking head 24 can be pushed after the pressing block 27 is pressed down, so that the locking head 24 is separated from the locking hole 26, and the sliding sleeve 12 can slide rapidly; the locking head 24 is constructed so as to be locked in the locking hole 26 and smoothly engaged with the push block 27.
As shown in fig. 5, a stopper 34 is disposed at one end of the inner side of the sliding sleeve 12 facing the first fixing rod 13, and the stopper 34 is connected to the stopper groove 30. The arrangement of the limiting block 34 enables a stable attaching area to be formed between the end of the limiting rod 31 and the sliding sleeve 12, so that the sliding sleeve 12 can be limited by the limiting rod 31, and meanwhile, the limiting block 34 enables the sliding sleeve 12 to be limited at a certain angle, so that the sliding sleeve 12 cannot rotate around the axis direction of the cross rod 15, and the sliding sleeve 12 can only move along the length direction of the cross rod 15, so that when the sliding sleeve 12 returns, the lock rod 23 can be accurately inserted into the jack 25.
As shown in fig. 4, the length of the stopper rod 31 coincides with the length of the fixing portion 28. This feature enables the extension 29 to be in a vertical position after the stop rod 31 is connected to the first fixing plate 17, which is convenient for use.
As shown in fig. 1, the outer diameter of the sliding sleeve 12 coincides with the outer diameter of the abutting portion 21, so that the outer surface of the sliding sleeve 12 is flush with the outer surface of the abutting portion 21. This feature allows the sliding sleeve 12 to be flush with the outer surface of the cross bar 15, without a transition zone, and facilitates hand-held or sitting-on use.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
