Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1, 2 and 3, a multi-functional crotch opening aid comprises a seat cushion 8, a rack 2, a bracket 1 and two unilateral leg modules. The support 1 is provided with a cushion mounting position which can be connected with a cushion 8. The middle part of the bracket 1 is provided with a slot. The rack 2 and the bracket 1 form a sliding pair. The rack 2 is provided with scale marks. The inner ends of the two single-side leg modules are respectively connected with the two sides of the bracket 1; the rack 2 is located between the inner ends of the two single-sided leg modules. The middle holding rod 3 is positioned between the two single-side leg modules, the inner end of the middle holding rod is hinged with the middle part of the bracket 1, and the outer end of the middle holding rod is fixed with a grab handle 3-1.

The single-sided leg module comprises a leg bar 4, a foot bar 5, a gear 6, a locking assembly 7 and a bottom stabilizer. The inner end of the leg rod 4 is fixed with a gear 6, and forms a rotating pair with the bracket 1. The gear 6 is engaged with the rack 2. The user can adjust the degree of opening of two unilateral supporting leg modules through pull rack 2. The outer end of the side surface of the leg supporting rod 4 is fixed with a foot rest rod 5. The axis of the foot bar 5 is perpendicular to the axis of the leg bar 4; the outer ends of the foot bars 5 in the two single side leg modules face in the same direction for the user to step on when in use. The bottom stabilizing frame comprises a connecting sleeve and an auxiliary supporting rod. The connecting sleeve is detachably sleeved at the outer end of the supporting leg rod 4. The inner ends of the three auxiliary supporting rods are respectively fixed with the inner ends of the three side surfaces of the connecting sleeve, and the outer ends of the three auxiliary supporting rods extend outwards in an inclined manner and are flush with the outer ends of the supporting rods; when mounted at the outer end of the leg bar 4, the multi-functional crotch aid can stably stand on the ground for a user to press legs or sit up.

The locking assembly 7 comprises a bidirectional ratchet 7-1, a pawl 7-2 and an adjusting wrench 7-3. The bidirectional ratchet wheel 7-1 and the gear 6 are coaxially fixed. The inner ends of the two pawls 7-2 are hinged with the bracket 1, and the outer ends of the two pawls respectively abut against two sides of the bidirectional ratchet 7-1. A spring is arranged between the pawl 7-2 and the bracket 1. The spring exerts a spring force on the pawl 7-2 against the bidirectional ratchet 7-1. The inner end of the adjusting wrench 7-3 is hinged with the bracket 1. An adjusting cam is fixed on the inner side of the adjusting wrench 7-3. The adjustment cam is rotated with the rotation of the adjustment wrench 7-3. The adjustment cam is located between the two bidirectional ratchets 7-1. Two unlocking convex parts are arranged on the adjusting cam; when the unlocking convex part on the adjusting cam is pressed against the pawl 7-2, the pawl 7-2 is separated from the bidirectional ratchet wheel 7-1.

The adjusting wrench 7-3 has three adjusting positions; the positioning and locking of the adjusting wrench 7-3 at three adjusting positions are realized by the mutual matching of the elastic lug on the adjusting wrench 7-3 and the three grooves on the bracket 1. When the adjusting wrench 7-3 is in the first adjusting position, one unlocking convex part of the adjusting cam is pressed against the first pawl 7-2, so that the first pawl 7-2 is separated from the bidirectional ratchet wheel 7-1; the second pawl 7-2 is propped against the bidirectional ratchet wheel 7-1; at this time, the leg lever 4 can only be rotated outward; when the adjusting wrench 7-3 is in the second adjusting position, one unlocking convex part of the adjusting cam is pressed against the second pawl 7-2, so that the second pawl 7-2 is separated from the bidirectional ratchet wheel 7-1; the first pawl 7-2 is abutted against the bidirectional ratchet wheel 7-1; at this time, the leg bar 4 can only rotate inwards; when the adjusting wrench 7-3 is in the third adjusting position, the two unlocking convex parts of the adjusting cam respectively abut against the two pawls 7-2, so that the two pawls 7-2 are separated from the bidirectional ratchet 7-1. At this time, the leg lever 4 can freely rotate. When one of the unilateral leg modules can only rotate inwards under the action of the corresponding locking assembly 7, and the other unilateral leg module can only rotate outwards under the action of the corresponding locking assembly 7, the two unilateral leg modules cannot rotate due to the fact that the gears 6 on the two unilateral leg modules are meshed with the same rack, and therefore bidirectional locking of the two unilateral leg modules is achieved.

The leg supporting rod 4 and the middle holding rod 3 both adopt telescopic structures and comprise an inner rod part and an outer sleeve; the outer sleeve is sleeved outside the inner rod part and forms a sliding pair with the inner rod part. A row of a plurality of locking holes are formed in the side surface of the outer sleeve along the length direction; the side surface of the end part of the inner rod part extending into the outer sleeve is provided with a locking marble; the length of the leg rod 4 can be adjusted by clamping the locking balls into different locking holes.

The multifunctional hip-opening aid has three working modes, namely a sitting stretching mode, a standing stretching mode and a side leg stretching mode.

As shown in fig. 1, in the sitting and stretching mode, the outer ends of the leg bars 4 are not provided with bottom stabilizers; the cushion 8 is separated from the bracket 1 and is installed on the ground. Support 1 and two unilateral leg modules are kept flat subaerial, and support 1 is located unilateral leg module and keeps away from one side of cushion 8, and foot rest lever 5 sets up. Both unilateral leg modules adjust the locking assembly 7 to a state in which the leg lever 4 can only be rotated outwards; the user sits on the seat cushion 8, pushes both feet against the foot rest levers 5, and then opens the crotch by spreading both legs outward.

In the standing stretch mode, as shown in fig. 2, the outer ends of the leg bars 4 are free of the bottom stabilizer, the seat cushion 8 is mounted on the frame 1, and the middle gripping bar 3 is removed. The two single-side leg modules are folded and erected. The user leans the multifunctional hip-opening aid against the wall, holds the wall surface by hand, sits on the cushion 8, and steps on the two pedal rods 5 by feet respectively. Both unilateral leg modules adjust the locking assembly 7 to a state in which the leg lever 4 can only be rotated outwards; the user can push the feet outwards to open the crotch; after the user opens the crotch to a proper degree, the locking assemblies 7 of one or two unilateral leg modules are adjusted to the state that the leg rods 4 can only rotate inwards, so that the two unilateral leg modules are kept locked, the multifunctional crotch opening assistor can provide support for the user, the user can keep the crotch opening state for a long time, and the crotch opening assisting effect is improved.

As shown in fig. 3, in the side leg pressing mode, when the two unilateral leg modules are folded, the locking assembly 7 of one unilateral leg module is adjusted to a state that the leg lever 4 can only rotate inwards, and the locking assembly 7 of the other unilateral leg module is adjusted to a state that the leg lever 4 can only rotate inwards, so that the two unilateral leg modules are kept locked, and the outer ends of the two leg levers 4 are provided with bottom stabilizing frames; the cushion 8 is arranged on the bracket 1; then, the multi-functional hip-open assistor is erected, and the user puts one leg on the seat cushion 8 to perform one-side leg pressing.
