[0002] Most patients with stroke and other neurological diseases also experience hemiplegia, and walking training is a crucial step in helping these patients regain their ability to walk. In addition, patients who experience difficulty walking due to accidents such as car crashes also require scientific walking training in addition to surgical and drug treatment.

[0003] Weight-loss gait training is a training method used to restore lower limb strength and walking ability. It reduces part or all of the patient's weight through suspension, allowing the patient to maintain balance and perform gait training, thereby enabling patients with insufficient lower limb strength to gradually regain their walking ability.

[0004] Most existing weight-loss gait training methods utilize ceiling-mounted suspension systems, along with slings and poles. This involves suspending the patient with their feet on the ground, and then using software algorithms to precisely train their gait and gradually restore leg muscle strength. However, the use of poles requires changing to accommodate different patient needs during training and transfers, which is inconvenient and consumes significant time for medical staff.

[0005] Therefore, there are still shortcomings and deficiencies in the existing technology. How to provide a multifunctional boom device and ceiling track system that does not require the replacement of different booms is a technical problem that urgently needs to be solved by those skilled in the art.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] This utility model provides a multifunctional boom device that can meet different needs. The two booms 1 can be quickly folded and unfolded through the X-shaped extension mechanism 2, thereby enabling the booms 1 to be switched and effectively saving time.

[0036] Please refer to this as well. Figures 1 to 4 The multifunctional boom device provided by this utility model includes:

[0037] Two booms 1, each boom 1 has a groove 102 along its length, and a first slider 202 and a second slider 203 are slidably connected in the groove 102;

[0038] The X-shaped extension mechanism 2 is located between two suspension rods 1 and is configured to allow the two suspension rods 1 to move closer to each other and further apart. The X-shaped extension mechanism 2 includes at least two connecting rods 201, which are distributed crosswise and rotate around the central axis 205. The two ends of one connecting rod 201 are respectively connected to two first sliders 202, and the two ends of the other connecting rod 201 are respectively connected to two second sliders 203. The central axis 205 is fixedly provided with a lifting ring 4 for connecting to the head 30 of the overhead track system.

[0039] At least one set of air damping adjustment device 3 is connected to the X-type extension mechanism 2 and is used to provide buffer damping when the X-type extension mechanism 2 is extended or retracted.

[0040] Two rods 1 are arranged in parallel. Each rod 1 has a limiting protrusion on the side that is close to each other. The limiting protrusion can limit the first slider 202 and the second slider 203 to prevent the first slider 202 and the second slider 203 from coming out of the side of the slide groove 102.

[0041] As the two connecting rods 201 in the X-shaped extension mechanism 2 rotate around the central axis 205, the two slings 1 can be brought closer together or moved further apart through the X-shaped extension mechanism 2, thus enabling the slings 1 to be switched to meet different patient needs. When the two slings 1 are brought together, the multi-functional sling device is suitable for patients to perform dynamic weight-loss walking training; when the two slings 1 are extended, the multi-functional sling device is suitable for transferring patients.

[0042] With this setup, when the overhead rail system switches between training and transfer modes, the multi-functional boom device can quickly merge or unfold the two booms 1 through the X-shaped extension mechanism 2. The switching is convenient and does not require replacement, saving time for medical staff and meeting the different needs of patients for dynamic weight loss walking training and transfer.

[0043] In some embodiments, please refer to the following: Figures 1 to 4 Both the first slider 202 and the second slider 203 are provided with fixing parts 204.

[0044] The fixing member 204 is used to move the first slider 202 and the second slider 203 during the conversion, and to fix the position of the first slider 202 and the second slider 203 after the conversion is completed.

[0045] In some embodiments, please refer to the following: Figures 1 to 4 The fixing component 204 includes a knob 2041 and a bolt 2042 fixed to the knob 2041. The rod 1 is provided with a guide groove 103 along its length. The bolt 2042 passes through the guide groove 103 and is slidably connected to the guide groove 103. The end of the bolt 2042 away from the knob 2041 is threadedly connected to the first slider 202 or the second slider 203.

[0046] During the conversion, knob 2041 is not tightened, allowing the first slider 202 and the second slider 203 to move. Knob 2041 drives the first slider 202 and the second slider 203 to slide within the groove 102 of the boom 1. At this time, bolt 2042 slides along the guide groove 103 of the boom 1. As the first slider 202 and the second slider 203 move, the two booms 1 move closer together or further apart via the X-shaped extension mechanism 2. After the conversion is complete, knob 2041 is tightened to press against the boom 1. At this point, the first slider 202 and the second slider 203 cannot slide within the groove 102, thus fixing their positions.

[0047] In some embodiments, please refer to the following: Figures 1 to 4 The air damping adjustment device 3 includes two symmetrically distributed air damping adjustment mechanisms 31, and the air damping adjustment mechanism 31 includes:

[0048] A cylinder 301 is fixedly mounted on the lifting rod 1, and a piston is slidably connected inside the cylinder 301.

[0049] The push rod 303 has one end fixedly connected to the piston and the other end fixedly connected to the first slider 202 or the second slider 203;

[0050] Airbag 302 is located below cylinder 301, and the interior of airbag 302 is connected to the interior of cylinder 301.

[0051] Specifically, the cylinder 301 and the airbag 302 are fixed inside the limiting sleeve 306, and the airbag 302 can be connected to the cylinder 301 through the connecting pipe.

[0052] In some embodiments, please refer to the following: Figures 1 to 4 An adjustment valve 305 is installed at one end of the airbag 302.

[0053] When the X-shaped extension mechanism 2 unfolds, the first slider 202 and the second slider 203 move towards each other within the groove 102 of the suspension rod 1. The first slider 202 and the second slider 203 drive the push rod 303 to move, which in turn drives the piston to move within the cylinder 301. As the piston moves, it compresses the internal air, generating a damping force. The compressed air enters the air bladder 302, causing it to inflate. The generated damping force acts as a buffer, preventing the X-shaped extension mechanism 2 of the multi-functional suspension rod from suddenly unfolding and affecting the patient's experience. During this process, the regulating valve 305 acts as an exhaust valve. A portion of the compressed air is discharged to the outside atmosphere through the regulating valve 305. The smaller the opening of the regulating valve 305, the more difficult the exhaust, the higher the pressure inside the cylinder 301, the greater the force required to push the push rod 303, the stronger the damping effect, and the slower and smoother the unfolding speed. Conversely, the larger the opening of the regulating valve 305, the easier the exhaust, the weaker the damping effect, and the faster and easier the unfolding. By changing the opening of the regulating valve 305, the magnitude of the damping force can be precisely controlled, making the unfolding of the X-type extension mechanism 2 more controlled and stable.

[0054] When the X-shaped extension mechanism 2 retracts, the air in the airbag 302 is first expelled through the regulating valve 305, and then the regulating valve 305 is closed. At this time, a negative pressure is formed inside the airbag 302 and the cylinder 301. The first slider 202 and the second slider 203 move in opposite directions, pulling the push rod 303 to move outward from the cylinder 301. Because the airbag 302 and the cylinder 301 are under negative pressure, a damping force is generated, making it difficult for the push rod 303 to drive the piston to move. This setting can play a buffering role, avoiding the sudden retraction of the X-shaped extension mechanism 2 of the multi-functional suspension device when the ceiling rail system suddenly switches between training and transfer modes due to unexpected situations, which would affect the patient's user experience.

[0055] In some embodiments, please refer to the following: Figures 1 to 4 A connecting shaft 304 is fixedly installed at the bottom of the boom 1, and two cylinders 301 in the two sets of air damping adjustment mechanisms 31 are fixedly installed on the connecting shaft 304.

[0056] Two cylinders 301 are located on both sides of the connecting shaft 304, and two sets of air damping adjustment mechanisms 31 are symmetrically distributed about the connecting shaft 304.

[0057] In some embodiments, please refer to the following: Figures 1 to 4 There are two sets of air damping adjustment devices 3, and the two sets of air damping adjustment devices 3 are respectively installed on two hangers 1.

[0058] In some embodiments, please refer to the following: Figures 1 to 4 There are three connecting rods 201, which are sequentially sleeved on the central shaft 205 from top to bottom. The two connecting rods 201 located at the top and bottom are respectively hinged to the two first sliders 202.

[0059] The connecting rod 201 has a through hole in its middle. The three connecting rods 201 are sleeved on the central shaft 205 through the through hole and can be rotated along the central shaft 205. The two connecting rods 201 located at the upper and lower parts are arranged in parallel. The two ends of these two connecting rods 201 are respectively hinged to the two first sliders 202 in the two lifting rods 1. The connecting rod 201 located in the middle is arranged to cross the two connecting rods 201 located at the upper and lower parts. The two ends of the connecting rod 201 located in the middle are respectively hinged to the two second sliders 203 in the two lifting rods 1.

[0060] In some embodiments, please refer to the following: Figures 1 to 4 The boom 1 has hooks 101 at both ends.

[0061] The multifunctional suspension device provided by this utility model allows two suspension rods 1 to quickly approach and merge or move away from each other through an X-shaped extension mechanism 2, thereby enabling the suspension rods 1 to be switched easily and to meet the different needs of patients.

[0062] When the patient needs to perform dynamic weight-loss walking training, the two suspension bars 1 are joined together and in a closed state. The patient can be lifted up through the hooks 101 at both ends of the suspension bars 1 to assist the patient in rehabilitation training. When the patient needs to be transferred, the two suspension bars 1 are separated and in an extended state. A sling bag can be connected through the four hooks 101 to lift the patient and transport the patient.

[0063] Please refer to Figure 5 In addition to the multifunctional boom device disclosed in the above embodiments, this utility model also provides a ceiling rail system including the above-mentioned multifunctional boom device. The ceiling rail system also includes a track 20 and a machine head 30. The track 20 is fixedly installed, the machine head 30 is installed on the track 20, and the multifunctional boom device is connected to the machine head 30 through a lifting ring 4.

[0064] The skyrail system includes a multi-functional boom device, thus enabling it to produce the same technical effect.
