Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

See fig. 1. Safety frame adjusting equipment includes arc limiting plate 1 and safety frame 2. In this embodiment, the load-bearing component is specifically a barbell frame 3, the arc-shaped limiting plate 1 is fixedly connected with the barbell frame 3, and the safety frame 2 is rotatably connected with the barbell frame 3, for example, the safety frame 2 is hinged on the barbell frame 3 through a rotating shaft.

See further fig. 2. Set up limiting plate through-hole 4 on the safety shelf 2, the free end of arc limiting plate 1 passes limiting plate through-hole 4 to the radius of rotation of limiting plate through-hole 4 matches with the radius of arc limiting plate 1, as long as can guarantee that safety shelf 2 when rotatory (when adjusting safety shelf adjusting device's the state of taking effect/relieving promptly) arc limiting plate 1 can shuttle smoothly in limiting plate through-hole 4, the direction that the arrow in figure 2 shows.

The positioning principle of the present invention is described below. Referring first to fig. 3, the arc-shaped limiting plate 1 is provided with a plurality of circular limiting holes 5 along the arc, and the safety shelf 2 is provided with limiting parts 6 matched with the limiting holes 5. When the safety shelf 2 rotates along the arc direction of the arc limiting plate 1, the safety shelf can be fixed at the corresponding position of each limiting hole 5. In one embodiment, when the safety frame 2 is fixed to the position-limiting hole 5-1 of the arc-shaped position-limiting plate 1, which is far from the free end, as can be seen from fig. 5, the included angle between the safety frame 2 and the horizontal plane decreases due to the rotation of the rotating shaft, the free end of the safety frame 2 cannot abut against the position-limiting post 18, and the safety frame 2 is inclined, so that the safety frame 2 does not collide with the position-limiting post 18 during the up-and-down movement of the barbell frame 3, that is, the safety frame adjusting device is in the "released" state. When the safety frame 2 is fixed in the position-limiting hole 5-2 near the free end of the arc-shaped position-limiting plate 1, as can be seen from fig. 6, the safety frame 2 is substantially perpendicular to the ground, the free end of the safety frame abuts against the position-limiting column 18, the momentum of the downward movement of the barbell frame 3 is stopped by the position-limiting column 18, and the safety frame adjusting device is in the "effective" state.

There are many ways to fix the safety frame 2 relative to the limiting hole 5 by using the limiting part 6, and one skilled in the art can select a suitable limiting part 6 from the prior art according to actual needs. As a simple and convenient realization scheme, the limiting part 6 comprises a pin hole arranged on the safety frame 2 and a pin bolt inserted into the pin hole, the pin hole is vertical to the through hole 4 of the limiting plate, and the outer diameter of the pin bolt is matched with the inner diameter of the limiting hole 5. After the pin bolt passes through the pin hole and is inserted into the limiting hole 5, the safety frame 2 can be fixed at the corresponding position of the limiting hole 5. Although the realization scheme has simple structure and convenient maintenance, the inconvenience of labor-consuming plugging and unplugging of the pin bolt also exists. As an improved scheme, a hollow tube 7, a spring 8, a positioning ball 9 and the like are adopted to form a limiting part 6 which is convenient to use. Referring to fig. 4, in one embodiment, a hollow tube 7 is fixedly disposed on the safety frame 2, and the axial direction of the hollow tube 7 is perpendicular to the arc-shaped limiting plate 1. The hollow tube 7 is open at one end and closed at the other end, and is provided with a spring 8 and a positioning ball 9. The locating ball 9 can be steel balls, the diameter of the locating ball is larger than that of the limiting hole 5, force is applied to the arc-shaped limiting plate 1 under the pushing of the spring 8, when the locating ball 9 is close to and coincides with the limiting hole 5, a part of the locating ball 9 is embedded into the limiting hole 5, and therefore the safety frame 2 and the arc-shaped limiting plate 1 are fixed relatively. Generally speaking, in the safety frame adjusting device used for the deep squatting trainer, two limiting holes 5 are provided, and the two limiting holes correspond to two states of 'effective' and 'released' respectively as described in the positioning principle; in practical use, the number of the limiting holes 5 is not particularly limited, and can be increased or decreased by a person skilled in the art according to the actual needs of the fitness equipment of the specific application of the safety frame adjusting equipment. When safety shelf 2 receives the exogenic action and moves along the circular arc direction of arc limiting plate 1, because locating ball 9 and spacing hole 5 are circular, after exerting pulling force and surpassing the threshold value, locating ball 9 atress and oppression spring 8 shrink, locating ball 9 breaks away from spacing hole 5, make safety shelf 2 can continue to move, until locating ball 9 reaches next spacing hole 5 department and imbeds this spacing hole 5 again, this process steel ball collision arc limiting plate 1 can make a sound and the resistance size takes place to show the change, finally safety shelf 2 is fixed in another spacing hole 5 position from being fixed in a spacing hole 5 position transform in addition, the change of its state has been realized.

As a modified scheme, one end of the hollow tube 7 is detachably provided with a blocking nut 10, the blocking of the hollow tube 7 is realized through the blocking nut 10, and two ends of the spring 8 respectively abut against the positioning ball 9 and the blocking nut 10; if the arc-shaped limiting plate 1 is blocked by the limiting part 6 of the hollow tube 7 due to a fault, the limiting can be released by detaching the blind nut 10 to release the locating ball 9.

Referring further to fig. 3, in order to prevent the safety shelf 2 from coming out of the arc-shaped limit plate 1 during the rotation process, which causes the fault of the dislocation of the parts, it is necessary to limit the moving range of the safety shelf 2. In one embodiment, the arc-shaped limiting plate 1 is provided with two positioning holes 11 along the arc, and the two positioning holes 11 are positioned at two ends of the plurality of limiting holes 5 and provide a barrier to block the safety shelf 2, so that the moving range of the safety shelf 2 is limited between the two positioning holes 11. In the actual installation use process, firstly, the positioning bolt 12 penetrates through the positioning hole 11 far away from the free end and is fixed by the nut, then, the arc-shaped limiting plate 1 is inserted into the limiting plate through hole 4, the positioning bolt 12 penetrates through the positioning hole 11 far away from the free end and is fixed by the positioning nut 13, meanwhile, the length of the positioning bolt 12 is ensured to be larger than the width of the limiting plate through hole 4, and the limiting plate through hole 4 is blocked by the bolt and the like when moving to the position of the positioning hole 11, so that the limitation on the movement range of the safety frame 2 is realized.

Example 2

On the basis of embodiment 1, it is laborious to directly pull the safety frame 2 to change its angular position (use state), and it is not easy to hold the bulky safety frame 2, for this reason, referring to fig. 1, an adjusting handle 14 may be provided on the safety frame 2 to facilitate the application of force. The adjustment handle 14 is simply fixed to the safety device, but the problem of labor-consuming state change cannot be solved, and in order to solve the problem, the lever principle can be used for facilitating operation. In this embodiment, referring to fig. 2, the safety frame adjustment apparatus further comprises a ^ shaped connecting member 15 rotatably connected to the barbell frame 3, the corner of the connecting member 15 is a rotating shaft, one end of which substantially directed to the ground is fixedly connected or integrally formed with the safety frame 2, and the other end is fixedly connected or detachably connected to the adjustment handle 14. In this way, it is possible to convert the rotation operation for the safety bar 2 into the lifting or pressing down of the adjustment handle 14 (since the movement range of the safety bar 2 is limited, the movement range of the adjustment handle 14 is approximately the up-and-down movement, correspondingly).

In actual use, the user may pay more attention to whether the user can automatically switch the use state of the safety frame 2 after training without the help of other people such as a coach. In this regard, with reference to fig. 5 or 6, in addition to the embodiment using the aforementioned adjustment handle 14, further using an adjustment handle 14 having a long handle portion 14-1, one end of the long handle portion 14-1 is connected with the connecting member 15 in a force-transmitting manner, while the other end extends away from the safety frame 2, for example, to the position of the user until reaching a position accessible to the user; an L-shaped grip portion 14-2 is further provided fixedly connected to the outwardly extending free end of the long handle portion 14-1, the L-shape lying in a plane perpendicular to the long handle portion 14-1. So, the user can vacate the hand and promote handheld portion 14-2 after the training to drive safety shelf 2 and move and fix a position towards the free end of arc limiting plate 1, make safety shelf 2 be located "take effect" state, its lower extreme leans on with spacing post 18, the user can leave the training device safely afterwards.

The squat training device comprises a bottom frame 16, an upper frame 17 arranged on the bottom frame 16 and a limit post 18 fixedly connected with the upper frame 17, wherein the safety frame 2 is in an effective state when the free end of the safety frame 2 of the safety frame adjusting device abuts against the limit post 18 (figure 6), and is in an effective state when the safety frame 2 rotates and the free end deviates from the limit post 18 (figure 5), and the deflection angle of the safety frame is set to be not in contact with the limit post 18 in the movement process. It is apparent that the restraining posts 18 are at a height and allow the barbell stand 3 in the "active" position to be "restrained" within its range of motion-not the starting position under the influence of pure gravity. The user can use the deep squatting trainer to train in a 'release' state (figure 5); after the training is finished, the grip part 14-2 of the adjusting handle 14 is pulled (in the direction of arrow shown in fig. 5 or 6) to drive the safety frame 2 to rotate, so that the safety frame adjusting device is in an effective state (fig. 6), and the user can safely leave the deep squat trainer.
