Description

Technical Field

[0001] The present application relates to the technical field of hanger adapters, and in particular to an elastic load-bearing device. Background Art

[0002] The weight loss rehabilitation system is an auxiliary training device widely used in the fields of neurological rehabilitation, orthopedic rehabilitation and sports rehabilitation. It is mainly used to help patients with motor dysfunction caused by nervous system damage (such as stroke, spinal cord injury, etc.) or musculoskeletal system diseases to perform early functional training such as standing and walking. The system provides a safe and controllable training environment by reducing the load of the patient's body weight on the lower limbs, thereby enhancing the patient's muscle strength, balance ability and gait coordination, and promoting the remodeling and recovery of neurological function. The weight loss rehabilitation system usually includes a weight loss support device, a walking training platform (such as a treadmill or gait training equipment) and a matching control system. Among them, the weight loss support device, as one of the core components, plays a key role in load bearing and safety assurance.

[0003] In weight loss rehabilitation systems, a ceiling rail load-bearing hanger is a common weight-loss support structure, typically consisting of a track fixed to the ceiling or a dedicated bracket and a hanging device that can slide along the track. The hanger is connected to a safety vest or support belt on the patient, transferring part of the patient's weight to the track system through the hanging device, thereby achieving a weight loss effect. The ceiling rail load-bearing hanger has the advantages of structural stability, flexible mobility, and small space occupation, and is widely used in various rehabilitation training centers and medical institutions. In addition, the hanger system is usually used in conjunction with an electric lifting device to achieve automatic adjustment of the hanging height, further improving the adaptability and comfort of training.

[0004] However, existing overhead rail load-bearing hangers still have significant technical flaws, particularly a lack of buffering during dynamic training. Gait training generates periodic impact forces, and existing overhead rail hangers, mostly rigidly connected structures, are unable to effectively absorb and buffer these impact forces. This results in the hanger system being prone to instability, such as shaking and trembling, during use. This not only affects the smoothness of training but can also cause discomfort and even safety hazards to patients. Furthermore, the lack of a buffering mechanism increases mechanical wear on the equipment, reducing its service life. Summary of the Invention

[0058] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0059] Reference Figures 1 to 6As shown, an elastic load-bearing device is proposed in an embodiment of the present application, which may include: a first connecting body 1, with a first accommodating chamber 101 built in, and a first opening 102 communicating with the first accommodating chamber 101 is opened on the first connecting body 1; a second connecting body 2, with a second accommodating chamber 201 built in, and a second opening 202 and a third opening 203 communicating with the second accommodating space are opened on the second connecting body 2, and the second opening 202 and the third opening 203 are arranged opposite to each other; a connecting component 3, embedded in the first accommodating chamber 101 and the second accommodating chamber 201 through the first opening 102 and the second opening 202, so that the first connecting body 1 and the second connecting body 2 are connected through the connecting component 3; and a buffer component 4, which is slidably configured in the second accommodating chamber 201 and can be extended and retracted on the second connecting body 2 in a sliding manner through the third opening 203;

[0060] When the buffer component 4 slides in a direction away from the first connecting body 1 , elastic energy can be stored between the buffer component 4 and the second connecting body 2 to form a buffering force.

[0061] Specifically, in the technical solution adopted in the present application, the first connecting body 1 and the second connecting body 2 can adopt a cylindrical structure, preferably a cylindrical structure, so that in the present application, the first connecting body 1 has a cylindrical first accommodating chamber 101, and a first opening 102 connected to the first accommodating chamber 101 is opened on the first connecting body 1, and the second connecting body 2 has a cylindrical second accommodating chamber 201, and a second opening 202 and a third opening 203 connected to the second accommodating chamber 201 are opened on the second connecting body 2, and the second opening 202 and the third opening 203 are located on the opposite end faces of the second connecting body 2. In an embodiment of the present application, the first connecting body 1 can be used to connect a sling, and the second connecting body 2 can be used to connect a limb fixation device, so as to achieve the purpose of transferring the target equipment, for example: the sling on the overhead rail electric transfer machine and the limb fixation device on the protective equipment. Therefore, it is necessary to connect the first connecting body 1 and the second connecting body 2, so that a connecting component 3 is provided between the first connecting body 1 and the second connecting body 2. The connecting component 3 is inserted into the first accommodating chamber 101 and the second accommodating chamber 201 in an embedded and limited manner, so that the first connecting body 1 and the second connecting body 2 are connected through the connecting component 3. The technical point of this application is that a buffer component 4 is slidably arranged in the second accommodating chamber 201. When the buffer component 4 slides in the second accommodating chamber 201 in a direction away from the first connecting body 1, it can be partially displaced to the outside of the second connecting body 2 through the third opening 203. When the buffer component 4 slides in the second accommodating chamber 201 in a direction close to the first connecting body 1, the buffer component 4 can be partially retracted from the outside of the second connecting body 2 into the second accommodating chamber 201. It can be understood that the buffer component 4 has a telescopic function on the second connecting body 2. When the buffer component 4 extends out of the second connecting body 2 through the third opening 203, elastic energy can be stored between the buffer component 4 and the second connecting body 2. When using the elastic load-bearing device proposed in the present application, the sling on the overhead rail electric transfer machine can be connected to the first connection body 1, and the limb fixing device on the protective equipment can be connected to the buffer component 4, so that when the overhead rail electric transfer machine and the protective equipment apply opposite pulling forces to the adapter accessory, the buffer component 4 slides in the second accommodating chamber 201 in a direction away from the first connection body 1 and slides out of the second connection body 2 through the third opening 203, so that the elastic energy between the buffer component 4 and the second connection body 2 can be used as a buffering force.

[0062] Further, refer to Figure 2 、 Figure 5 、 Figure 6 and Figure 7As shown, in some embodiments, the buffer assembly 4 includes: a sliding rod 41, having a first rod body 411 and a first limit head 412; the first rod body 411 is passed through the third opening 203, and the first limit head 412 is extended into the second accommodating chamber 201 by the first rod body 411, and the size of the first limit head 412 is larger than the size of the third opening 203; a first elastic element 42 is sleeved on the first rod body 411, and the first elastic element 42 is elastically supported between the first limit head 412 and the end wall of the second connecting body 2 near the third opening 203; so that when the sliding rod 41 slides out of the second accommodating chamber 201 through the third opening 203, the first limit head 412 can compress the first elastic element 42 to store elastic energy.

[0063] Specifically, in the technical solution adopted in the present application, in order to realize the limited sliding of the buffer component 4 in the second accommodating chamber 201 and to be able to store elastic energy between the buffer component 4 and the second connecting body 2. The buffer component 4 in this embodiment may include: a sliding rod 41 and a first elastic element 42, the sliding rod 41 has a first rod body 411 and a first limiting head 412, the first rod body 411 is an elongated structure, and is passed through the third opening 203, and the first limiting head 412 is provided on the end of the first rod body 411, so as to be located in the second accommodating chamber 201 through the extension of the first rod body 411, so that when the first rod body 411 slides toward the outside of the second connecting body 2 through the third opening 203, since the size of the first limiting head 412 is larger than the size of the third opening 203, the maximum sliding distance of the first rod body 411 is limited. The first elastic element 42 can be a pressure spring, which is sleeved on the first rod body 411, and the elastic forces at both ends of the first elastic element 42 are supported on the first limit head 412 and the end wall of the second connecting body 2 near the third opening 203. When the first rod body 411 slides toward the outside of the second connecting body 2 through the third opening 203, the first limit head 412 gradually approaches the third opening 203 and compresses the first elastic element 42, thereby forming an elastic energy storage between the first limit head 412 and the second connecting body 2 through the first elastic element 42 in a compressed state, and using it as a buffering force. When the first elastic element 42 releases the elastic energy storage and rebounds, it can drive the sliding rod 41 to retract into the second accommodating chamber 201, so that the sliding rod 41 returns to its initial position.

[0064] Reference Figure 2As shown, in one embodiment, the device may further include a buffer pad 14 disposed in the second accommodating chamber 201. The buffer pad 14 corresponds to the end of the buffer assembly 4 facing away from the third opening 203, so that when the buffer assembly 4 rebounds, it can contact the buffer pad 14 to cushion the rebound force. Specifically, the buffer pad 14 can be disposed on the connecting assembly 3, preferably a rubber pad made of a flexible material, and the buffer pad 14 corresponds to the end surface of the first limit head 412 facing away from the first rod body 411.

[0065] Further, refer to Figure 2 and Figure 8 As shown, in some embodiments, it also includes: a first shaft sleeve 5, which is configured on the third opening 203 in an embedded manner, and the first rod body 411 can be slidably passed through the first shaft sleeve 5; the first shaft sleeve 5 has an embedded portion 51 and a overlapping portion 52, the embedded portion 51 is located in the third opening 203, the overlapping portion 52 extends into the second accommodating chamber 201, and the size of the overlapping portion 52 is larger than the size of the third opening 203, so that the overlapping portion 52 is supported on the end wall of the second connecting body 2; one end of the first elastic element 42 abuts on the first limit head 412, and the other end of the first elastic element 42 abuts on the overlapping portion 52.

[0066] Specifically, in the technical solution adopted in the present application, the first shaft kit 5 can be made of a material with flexible properties, such as rubber. The first shaft sleeve 5 has an embedding portion 51 and an overlapping portion 52. The embedding portion 51 is set to a cylindrical structure that is compatible with the third opening 203 and is fixed in the third opening 203. When the first rod body 411 is slidably inserted into the third opening 203, the embedding portion 51 is located between the first rod body 411 and the inner wall of the third opening 203; and the overlapping portion 52 can be set to a disc-shaped structure larger than the third opening 203, and is supported on the end wall of the second connecting body 2 close to the third opening 203, so that one end of the first elastic element 42 abuts on the first limit head 412, and the other end abuts on the overlapping portion 52, so that the first elastic element 42 is elastically supported on the second connecting body 2 through the overlapping portion 52, so that the first elastic element 42 and the second connecting body 2 are in flexible contact, thereby extending the service life of the first elastic element 42, avoiding damage caused by long-term rigid contact between the first elastic element 42 and the second connecting body 2, and reducing the probability of failure of the elastic characteristics of the first elastic element 42.

[0067] Further, refer to Figure 1 、 Figure 2 and Figure 7 As shown, in some embodiments, it further includes: a hanging ring 6 connected to the end of the first rod 411 away from the first limiting head 412, and the hanging ring 6 is used to connect the limb fixing device.

[0068] Specifically, in the technical solution adopted in this application, in order to enable the buffer assembly 4 to be connected to the limb restraint device, a lifting ring 6 can be provided on the end of the first rod 411 facing away from the first stopper 412. The lifting ring 6 can be fixed to the first rod 411 by embedding. During use, the limb restraint device on the protective equipment can be inserted through the lifting ring 6, so that the first rod 411 can be easily connected to the limb restraint device through the lifting ring 6.

[0069] Further, refer to Figure 2 、 Figure 5 、 Figure 6 and Figure 9 As shown, in some embodiments, the second connecting body 2 is provided with a first limiting through hole 204 on the opposite side wall near the second opening 202; the connecting component 3 includes: a connecting shaft 31, having a second rod body 311 and a second limiting head 312; the second rod body 311 is passed through the first opening 102 and the second opening 202 and is arranged in the first accommodating chamber 101 and the second accommodating chamber 201, and a first plug hole 313 is provided on the second rod body 311; the second limiting head 312 is located in the first accommodating chamber 101, and the size of the second limiting head 312 is larger than the size of the first opening 102, and the second rod body 311 is limited and fixed in the first accommodating chamber 101 by the second limiting head 312; the first limiting pin 32 is passed through the first limiting through hole 204 and the first plug hole 313 in a plug-in connection manner to limit and fix the second rod body 311 in the second accommodating chamber 201.

[0070] Specifically, in the technical solution adopted in the present application, the first limiting through hole 204 opened on the second connecting body 2 is used to limit and fix the connecting component 3 in the second accommodating chamber 201. In this embodiment, the connecting component 3 may include: a connecting shaft 31 and a first limiting pin 32. The connecting shaft 31 has a second rod body 311 and a second limiting head 312. The second rod body 311 is an elongated structure and can pass through the first opening 102 and the second opening 202 to pass through the first accommodating chamber 101 and the second accommodating chamber 201. The second limiting head 312 is arranged at the end of the second rod body 311 and is located in the first accommodating chamber 101. Since the size of the second limiting head 312 is larger than the first opening 102, The second limiting head 312 can limit the second rod 311 from being moved out of the first accommodating chamber 101 through the first opening 102. A first insertion hole 313 is formed on the second rod 311 and is located in the second accommodating chamber 201 so that the first insertion hole 313 can overlap with the first limiting through hole 204. The first limiting pin 32 is inserted through both the first limiting through hole 204 and the first insertion hole 313, thereby limiting the second rod 311 from being moved out of the second accommodating chamber 201 through the second opening 202 through the first limiting through hole 204. When the connecting shaft 31 needs to be disassembled from the second connecting body 2, the first limiting pin 32 can be pulled out of the first limiting through hole 204 to remove the connecting shaft 31 from the second opening 202 and the second accommodating chamber 201.

[0071] Further, refer to Figure 10 As shown, in some embodiments, the connecting assembly 3 also includes: a second shaft kit 33, which is sleeved on the second rod body 311 and located in the second accommodating chamber 201, and the second shaft kit 33 is supported between the second rod body 311 and the inner side wall of the second connecting body 2; a second socket is provided on the second shaft kit 33, and the second socket coincides with the first socket 313.

[0072] Specifically, in the technical solution adopted in the present application, a second shaft sleeve 33 is sleeved on the second rod body 311 of the connecting shaft 31, so that when the second rod body 311 is inserted into the second accommodating chamber 201 through the second opening 202, the second shaft sleeve 33 can fill the installation gap between the second rod body 311 and the second connecting body 2, thereby preventing the second rod body 311 from shaking in the second accommodating chamber 201, so that the connection between the second rod body 311 and the second connecting body 2 is more stable. In one embodiment, the second shaft kit 33 can be made of a flexible material, for example, rubber material, so that when the second shaft kit 33 is pressed between the second rod body 311 and the inner wall side wall of the second link body, the second shaft kit 33 can be flexibly deformed, which can not only fill the installation gap between the second rod body 311 and the second connection body 2 with a higher degree of adaptability, but also can transform the rigid contact between the second rod body 311 and the second connection body 2 into a flexible contact, thereby effectively avoiding irreversible loss caused by the long-term rigid contact between the second rod body 311 and the second connection body 2 during long-term use, and significantly improving the service life of the elastic load-bearing device proposed in this application.

[0073] Further, refer to Figure 2 As shown, in some embodiments, it also includes: a bearing member 7, which is installed in the first accommodating chamber 101, and the bearing member 7 is sleeved on the second rod body 311, so that the second rod body 311 can rotate based on the first connecting body 1 through the bearing member 7.

[0074] Specifically, in the technical solution adopted in the present application, since one end of the second rod 311 is fixed in the second accommodating chamber 201 by the second limiting head 312, and the second rod 311 is not restricted from rotating based on the first connecting body 1, the connecting shaft 31 can rotate based on the first connecting body 1. In this embodiment, in order to make the rotation of the connecting shaft 31 based on the first connecting body 1 more stable, a bearing member 7 is further configured in the first accommodating chamber 101, so that the connecting shaft 31 can rotate through the bearing member 7; the bearing member 7 can be selected from existing thrust ball bearings and is configured on the side wall of the second accommodating chamber 201 where the first opening 102 is opened. The bearing member 7 is sleeved on the second rod 311 of the connecting shaft 31, and the second rod 311 can rotate based on the first connecting body 1 through the bearing member 7, effectively reducing the friction generated between the second rod 311 and the first connecting body 1 during rotation.

A mounting cover 13 is also provided on the mounting port 105, and the mounting cover 13 can be detachably configured on the mounting port 105 by fastening screws. When it is necessary to assemble or disassemble the connecting shaft 31 and the bearing member 7, the fastening screws can be unscrewed to remove the mounting cover 13 from the mounting port 105, so that the connecting shaft 31 and the bearing member 7 can be loaded and unloaded or replaced through the mounting port 105.

[0076] Further, refer to Figure 2 and Figure 3 As shown, in some embodiments, the first connecting body 1 is provided with a mounting slot 103 and a second limiting through hole 104, the mounting slot 103 is located on the end face of the first connecting body 1 facing away from the second connecting body 2, and the second limiting through hole 104 is opened on the opposite side wall of the first connecting body 1, and the second limiting through hole 104 can pass through the mounting slot 103; the elastic load-bearing device also includes: a second limiting pin 8, which is passed through the second limiting through hole 104; a connecting plate 9, having a first connecting hole 901 and a second connecting hole 902 located below the first connecting hole 901; the first connecting hole 901 is used to connect a sling; the connecting plate 9 is sleeved on the second limiting pin 8 in the mounting slot 103 through the second connecting hole 902.

[0077] Specifically, in the technical solution adopted in the present application, a mounting slot 103 and a second limiting through hole 104 are provided on the first connecting body 1. The mounting slot 103 is located at the top of the first connecting body 1, specifically on the end face of the first connecting body facing away from the second connecting body, and the second limiting through hole 104 is located on the opposite side wall of the first connecting body 1, and the second limiting through hole 104 can pass through the mounting slot 103 horizontally, and a second limiting pin 8 is arranged in the second limiting through hole 104, so that part of the second limiting pin 8 can be exposed in the mounting slot 103. A connecting plate 9 is configured in the mounting slot 103, and the connecting plate 9 has a first connecting hole 901 and a second connecting hole 902. The first connecting hole 901 is located above the second connecting hole 902 based on the mounting slot 103. The first connecting hole 901 is used to connect the sling, and the second connecting hole 902 is fixed in the mounting slot 103 by a second limiting pin 8 sleeved in the mounting slot 103.

[0078] Further, refer to Figure 2 、 Figure 11 and Figure 12As shown, in some embodiments, it also includes: a push-up component 10, installed on the first connecting body 1, blocking one end of the second limiting through hole 104; a second elastic element 11, located in the second limiting through hole 104, elastically supported between the push-up component 10 and the second limiting pin 8; the second limiting pin 8 is slidably installed in the second limiting through hole 104, and the second limiting pin 8 has a first pin rod segment 801 and a second pin rod segment 802, and the size of the first pin rod segment 801 is smaller than the size of the second pin rod segment 802; a limiting connection port 903 connected to the second connecting hole 902 is provided on the connecting plate 9, and the size of the limiting connection port 903 is larger than the size of the first pin rod segment 801 and smaller than the size of the second pin segment 802.

[0079] Specifically, in the technical solution adopted in the present application, the push-up component 10 can be a headless screw, which can be detachably mounted on one end of the second limiting through hole 104 in a threaded manner, and the second limiting pin 8 can slide in the second limiting through hole 104, so that a second elastic element 11 can be configured between the second limiting pin 8 and the push-up component 10, and the second elastic element 11 is elastically supported between the second limiting pin 8 and the push-up component 10. In this embodiment, two different gear sections can be set on the second limit pin 8, which are divided into a first pin section 801 and a second pin section 802, and the size of the first pin section 801 is smaller than the size of the second pin section 802, and a limit connection port 903 connected to the second connection hole 902 is provided on the connecting plate 9, so that by switching the first pin section 801 and the second pin section 802 on the second limit pin 8, it is possible to control whether the second limit pin 8 needs to pass through the limit connection port 903 to pass through the second connection hole 902. Specifically, the size of the limit connection hole is set to be larger than the first pin section 801 and smaller than the second pin section 802. When in use, since there is an elastic support of the second elastic element 11 between the second limit pin 8 and the supporting component 10, the second limit pin 8 is in the normal state with the second pin rod section 802 in the installation slot 103. When the second limit pin 8 is driven to slide in the second limit through hole 104, the second elastic element 11 is compressed to store elastic energy, so that the second pin rod section 802 in the installation slot 103 is changed to the first pin rod section 801. At this time, the connecting plate 9 can be inserted into the installation slot 103, and the second connecting hole 902 is sleeved on the first pin rod section 801 through the limiting connecting port 903, releasing the elastic energy stored in the second elastic element 11, so that the second limit pin 8 returns to its position, thereby switching the first pin rod section 801 in the installation slot 103 to the second pin rod section 802. Since the size of the second pin section 802 is larger than the size of the limiting connecting port 903, the connecting plate 9 is limited and fixed in the installation slot 103. If the connecting plate 9 needs to be removed, press the second limit pin 8 away from the end of the supporting component 10, so that the second limit pin 8 slides in the second limit through hole 104, thereby switching the second pin rod segment 802 in the mounting slot 103 to the first pin rod segment 801, and then the connecting plate 9 can be removed from the mounting slot 103 by passing through the first pin rod segment 801 through the limit connection port 903.

[0080] Further, refer to Figure 2 、 Figure 4 and Figure 11As shown, in some embodiments, it also includes: a keycap 12, which is sleeved on the end of the second limit pin 8 away from the second elastic element 11; the second limit hole 104 has a first perforation section 104a and a second perforation section 104b; the aperture of the first perforation section 104a is larger than the size of the keycap 12, so that the keycap 12 can slide in the first perforation section 104a through the second limit pin 8; the aperture of the second perforation section 104b is smaller than the size of the keycap 12, so as to limit the maximum sliding distance of the second limit pin 8 in the second limit hole 104 through the keycap 12 and the second perforation section 104b.

[0081] Specifically, in the technical solution adopted in the present application, a keycap 12 can also be configured at the end of the second limit pin 8 to be able to represent the key position on the first connecting body 1 for easy manual operation, and the keycap 12 can also increase the contact area with the human body to reduce the pressure applied to the human body, thereby reducing the discomfort caused by pressing the key. In this embodiment, in order to avoid excessive compression of the second elastic element 11 when driving the second limit pin 8 to slide to switch the first pin segment 801 and the second pin segment 802, the second limit through hole 104 can also be set to be composed of a first perforated segment 104a and a second perforated segment 104b. The first perforated segment 104a can be used to cooperate with the sliding of the keycap 12, so that the aperture of the first perforated segment 104a is larger than the size of the keycap 12, and the second perforated segment 104b is used to limit the sliding of the keycap 12. The second perforated section 104b is set on one side of the first perforated section 104a close to the second elastic element 11, and the aperture of the second perforated section 104b is smaller than the size of the keycap 12, so that the maximum sliding distance of the keycap 12 in the second limiting through hole 104 can be limited by the second perforated section 104b, so that after the keycap 12 is installed at the end of the second limiting pin 8, the second limiting pin 8 can be effectively prevented from excessively compressing the second elastic element 11 through the cooperation of the keycap 12 and the second perforated section 104b.
