Detailed Description
The following provides embodiments of the present invention with reference to the accompanying drawings to explain technical solutions of the present invention in detail. It should be noted that the following description of the embodiments of the present invention with reference to the accompanying drawings is not intended to limit the present invention, and all similar structures and modifications thereof should be included in the scope of the present invention.
As shown in fig. 1-6, the ligament stretcher of the present invention is composed of a base 1, a left swing arm 3, a right swing arm 4, a transmission system 2, a lower waist bar 5, and a sit-up assembly 6.
As shown in fig. 1-4, the base 1 is provided with a seat 102, two connectors 103, and a fixing plate 101, wherein both connectors 103 can rotate around a shaft, and the fixing plate 101 is fixed on the base 1 through a fastener; as shown in fig. 1-6 and 12, the left swing arm 3 is pivotally connected to a connector 103 of the base 1 via a fastener; as shown in fig. 1-6 and fig. 11, the right swing arm 4 is pivotally connected to a connector 103 of the base 1 via a fastener; as shown in fig. 1-10, the transmission system 2 is disposed on the base 1, and includes a handwheel 201, a handwheel rotating shaft 202, a connector 203, a commutator 204, a screw 205, and a driving block 206, wherein the screw 205 is disposed on the base 1 through a bearing, the commutator 204 connects the screw 205 and the connector 203 through a fastener, the handwheel rotating shaft 202 is sleeved on the connector 203, the handwheel rotating shaft 202 is connected with the handwheel 201 through a fastener, the driving block 206 is sleeved on the screw 205, the driving block 206 is pivoted with the two connectors 103 of the base 1 through fasteners, and in actual implementation, the commutator 204 may be a universal joint or a bevel gear; as shown in fig. 1-2 and 13-15, the lower lumbar rod 5 is connected with the fixing plate 101 of the base 1 by a fastener; the sit-up component 6 is arranged at one end of the lower waist rod 5 through a fastener, the sit-up component 6 is composed of a support 601, two first holding sleeves 602, two second holding sleeves 603 and a third holding sleeve 604, the first holding sleeves 602, the second holding sleeves 603, 603 and the third holding sleeves 604 are respectively sleeved on the support 601, and the support 601 is arranged on the lower waist rod 5 through the fastener.
As shown in fig. 1-15, when using the machine, a user can sit on the seat 102 of the base 1, place a left leg on the left swing arm 3, place a right leg on the right swing arm 4, rotate the handwheel shaft 202 by rotating the handwheel 201, then drive the connector 203 to rotate, then drive the commutator 204 to rotate, then drive the screw 205 to rotate, and finally move the driving block 206, because the driving block 206 is respectively pivoted with the left swing arm 3 and the right swing arm 4 through the two connectors 103, the movement of the driving block 206 moves the left swing arm 3 and the right swing arm 4, and finally the left leg and the right leg of the user can move towards both sides, thereby achieving the purpose of exercising the flexibility of the leg ligament.
