Description

Technical Field

[0001] This application relates to the technical field of hanger adapters, and more particularly to a flexible load-bearing device. Background Technology

[0002] Weight-loss rehabilitation systems are assistive training devices widely used in neurological, orthopedic, and sports rehabilitation. They are primarily used to help patients with motor dysfunction due to neurological injuries (such as stroke, spinal cord injury, etc.) or musculoskeletal diseases to perform early functional training such as standing and walking. By reducing the load of the patient's body weight on the lower limbs and providing a safe and controllable training environment, the system enhances the patient's muscle strength, balance, and gait coordination, promoting the remodeling and recovery of neurological function. Weight-loss rehabilitation systems typically include a weight-loss support device, a walking training platform (such as a treadmill or gait training equipment), and a corresponding control system. The weight-loss support device, as a core component, plays a crucial role in load-bearing and safety.

[0003] In weight-loss rehabilitation systems, ceiling-mounted weight-bearing gantry systems are a common weight-bearing support structure, typically consisting of a track fixed to the ceiling or a dedicated bracket and a suspension device that slides along the track. This gantry transfers a portion of the patient's weight to the track system via the suspension device by connecting a safety vest or support strap to the patient, thus achieving a weight-loss effect. Ceiling-mounted weight-bearing gantry systems offer advantages such as structural stability, flexible movement, and minimal space occupation, making them widely used in various rehabilitation training centers and medical institutions. Furthermore, this gantry system is often used in conjunction with an electric lifting device, enabling automatic adjustment of the suspension height and further enhancing the adaptability and comfort of training.

[0004] However, existing overhead track load-bearing gantry systems still have significant technical shortcomings, particularly the lack of cushioning during dynamic training. Patients experience periodic impact forces during gait training, and existing overhead track gantry systems, mostly rigid connections, cannot effectively absorb and cushion these impacts. This leads to instability issues such as swaying and shaking during use, affecting the stability of training and potentially causing discomfort or even safety hazards for patients. Furthermore, the lack of a cushioning mechanism increases mechanical wear and reduces the lifespan of the equipment. Utility Model Content

[0005] This application provides an elastic load-bearing device, through which the protective device on the ceiling-mounted electric transfer machine and the rehabilitation training equipment can be connected, solving the technical problem of the lack of buffer function in the load-bearing hanger.

[0010] In one embodiment, it further includes: a lifting ring, connected to the end of the first rod away from the first limiting head, the lifting ring being used to connect the limb fixation device.

[0011] In one embodiment, the second connecting body has a first limiting through hole on the opposite side wall near the second opening; the connecting assembly includes: a connecting shaft having a second rod and a second limiting head; the second rod passes through the first opening and the second opening into the first receiving chamber and the second receiving chamber, and the second rod has a first insertion hole; the second limiting head is located in the first receiving chamber, and the size of the second limiting head is larger than the size of the first opening, and the second rod is limited and fixed in the first receiving chamber by the second limiting head; a first limiting pin passes through the first limiting through hole and the first insertion hole in a plug-in connection manner to limit and fix the second rod in the second receiving chamber.

[0012] In one embodiment, the connecting assembly further includes: a second shaft assembly sleeved on the second rod body and located in the second receiving chamber, the second shaft assembly being supported between the inner sidewall of the second rod body and the second connecting body; the second shaft assembly is provided with a second insertion hole, and the second insertion hole coincides with the first insertion hole.

[0013] In one embodiment, it further includes: a bearing element installed in the first receiving chamber, and the bearing element being sleeved on the second rod body so that the second rod body can rotate based on the first communicating body through the bearing element.

[0014] In one embodiment, the first connecting body is provided with a mounting slot and a second limiting through hole. The mounting slot is located on the end face of the first connecting body opposite to the second connecting body, and the second limiting through hole is formed on the opposite side wall of the first connecting body, and the second limiting through hole can penetrate the mounting slot. The elastic load-bearing device further includes: a second limiting pin, which passes through the second limiting through hole; a connecting plate, which has a first connecting hole and a second connecting hole located below the first connecting hole; the first connecting hole is used to connect a lifting rope; the connecting plate is sleeved on the second limiting pin in the mounting slot through the second connecting hole.

[0015] In one embodiment, it further includes: a stop component, installed on the first connecting body, blocking one end of the second limiting through hole; a second elastic element, located in the second limiting through hole, elastically supported between the stop component and the second limiting pin; the second limiting pin is slidably installed in the second limiting through hole, and the second limiting pin has a first pin segment and a second pin segment, the size of the first pin segment being smaller than the size of the second pin segment; the connecting plate is provided with a limiting connection port communicating with the second connecting hole, the size of the limiting connection port being larger than the size of the first pin segment and smaller than the size of the second pin segment.

[0017] Compared with existing technologies, the elastic load-bearing device proposed in the above technical solution incorporates a buffer component in the adapter accessory. Combined with the structural design of the first connecting body, the second connecting body, and the connecting component, it effectively absorbs and releases dynamic impact forces under load, thereby significantly improving the stability and safety of the equipment during use. Specifically, by setting a buffer component that can be slidably configured in the second receiving chamber, it can extend and retract relative to the second connecting body, achieving elastic energy storage during relative movement. Thus, when the load-bearing hanger is subjected to dynamic tensile or impact forces, the elastic deformation of the buffer component can absorb some energy, effectively mitigating the vibration and swaying of the hanger system and improving the stability of equipment operation. This structural design not only has a rapid response and significant buffering effect, but also a compact structure that is easy to integrate, making it suitable for various types of ceiling track load-bearing hanger systems.

[0018] In summary, the load-bearing hanger adapter proposed in this application effectively solves the problem of the lack of buffer function in existing overhead rail load-bearing hangers by introducing a buffer component with telescopic and elastic energy storage functions. This improves the safety, stability and comfort of the weight loss and rehabilitation system during dynamic training, and has significant technological progress and broad application prospects.

[0058] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0059] Reference Figures 1 to 6As shown in the embodiments of this application, an elastic load-bearing device is proposed. The elastic load-bearing device may include: a first connecting body 1, which has a first receiving chamber 101 inside and a first opening 102 communicating with the first receiving chamber 101; a second connecting body 2, which has a second receiving chamber 201 inside and a second opening 202 and a third opening 203 communicating with the second receiving chamber, and the second opening 202 and the third opening 203 are arranged opposite to each other; a connecting component 3, which is embedded in the first receiving chamber 101 and the second receiving 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 by the connecting component 3; and a buffer component 4, which is slidably disposed in the second receiving chamber 201 and can extend and retract 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, the buffer component 4 and the second connecting body 2 can elastically store energy to form a buffering force.

[0061] Specifically, in the technical solution adopted in this application, the first connecting body 1 and the second connecting body 2 can adopt a cylindrical structure, preferably a cylindrical structure. In this application, the first connecting body 1 has a cylindrical first receiving chamber 101, and a first opening 102 communicating with the first receiving chamber 101 is provided on the first connecting body 1. The second connecting body 2 has a cylindrical second receiving chamber 201, and a second opening 202 and a third opening 203 communicating with the second receiving chamber 201 are provided on the second connecting body 2. The second opening 202 and the third opening 203 are located on opposite end faces of the second connecting body 2. In the embodiments of this application, the first connecting body 1 can be used to connect a suspension rope, and the second connecting body 2 can be used to connect a limb fixation device to achieve the purpose of transferring the target equipment, such as the suspension rope on a ceiling-mounted electric transfer machine and the limb fixation device on a protective device. 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 receiving chamber 101 and the second receiving chamber 201 in an embedded and limiting manner, so that the first connecting body 1 and the second connecting body 2 are connected by the connecting component 3. The key technical point of this application is that a buffer component 4 is slidably disposed in the second receiving chamber 201. When the buffer component 4 slides in the second receiving 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 receiving chamber 201 in a direction closer to the first connecting body 1, the part of the buffer component 4 that is outside the second connecting body 2 can retract into the second receiving 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 storage can be performed between the buffer component 4 and the second connecting body 2. When using the elastic load-bearing device proposed in this application, the suspension rope on the electric transfer machine can be connected to the first connecting body 1, and the limb fixation device on the protective equipment can be connected to the buffer assembly 4. Thus, when the electric transfer machine and the protective equipment apply opposite pulling forces to the adapter, the buffer assembly 4 slides in the second receiving chamber 201 in a direction away from the first connecting body 1 and slides out of the second connecting body 2 through the third opening 203, thereby storing the elastic energy between the buffer assembly 4 and the second connecting body 2 as a buffering force.

[0062] Furthermore, 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 limiting head 412; the first rod body 411 passes through the third opening 203, and the first limiting head 412 is provided in the second receiving chamber 201 through the extension of the first rod body 411, and the size of the first limiting 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 limiting head 412 and the end wall of the second connecting body 2 near the third opening 203; thereby, when the sliding rod 41 slides out of the second receiving chamber 201 through the third opening 203, the first limiting head 412 can compress the first elastic element 42 to store elastic energy.

[0063] Specifically, in the technical solution adopted in this application, in order to realize the limited sliding of the buffer assembly 4 in the second receiving chamber 201 and to store elastic energy between the buffer assembly 4 and the second connecting body 2, the buffer assembly 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 has a long strip structure and passes through the third opening 203, while the first limiting head 412 is disposed on the end of the first rod body 411 so that it is located in the second receiving chamber 201 through the extension of the first rod body 411. Thus, when the first rod body 411 slides outward from the second connecting body 2 through the third opening 203, the size of the first limiting head 412 is larger than the size of the third opening 203, thereby limiting the maximum sliding distance of the first rod body 411. The first elastic element 42 can be a compression spring, sleeved on the first rod 411, and the two ends of the first elastic element 42 are elastically supported on the end walls of the first limiting head 412 and the second connecting body 2 near the third opening 203. When the first rod 411 slides outward through the third opening 203, the first limiting head 412 gradually approaches the third opening 203 and compresses the first elastic element 42. Thus, the first elastic element 42 in the compressed state forms an elastic energy storage between the first limiting head 412 and the second connecting body 2, and uses it as a buffer force. When the first elastic element 42 releases the elastic energy and rebounds, it can drive the sliding rod 41 to retract into the second receiving chamber 201, so that the sliding rod 41 returns to its initial position.

[0064] Reference Figure 2As shown, in one embodiment, it may further include a buffer pad 14 disposed in the second receiving chamber 201, and the buffer pad 14 corresponds to the end of the buffer assembly 4 opposite to the third opening 203, so that it can contact the buffer pad 14 when the buffer assembly 4 rebounds, thereby buffering its rebound force. Specifically, the buffer pad 14 can be disposed on the connecting assembly 3, preferably a rubber pad made of flexible material, and the buffer pad 14 corresponds to the end face of the first limiting head 412 opposite to the first rod body 411.

[0065] Furthermore, refer to Figure 2 and Figure 8 As shown, in some embodiments, it further includes: a first shaft assembly 5, which is embedded in the third opening 203, and a first rod 411 is slidably inserted in the first shaft assembly 5; the first shaft assembly 5 has an embedding portion 51 and an overlapping portion 52, the embedding portion 51 is located in the third opening 203, the overlapping portion 52 extends into the second receiving 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 against the first limiting head 412, and the other end of the first elastic element 42 abuts against the overlapping portion 52.

[0066] Specifically, in the technical solution adopted in this application, the first shaft assembly 5 can be made of a material with flexible properties, such as rubber. The first shaft assembly 5 has an insert portion 51 and an overlap portion 52. The insert portion 51 is configured as a cylindrical structure adapted to the third opening 203 and fixed in the third opening 203. When the first rod 411 is slidably inserted into the third opening 203, the insert portion 51 is located between the first rod 411 and the inner wall of the third opening 203. The overlap portion 52 can be configured as a disc-shaped structure larger than the third opening 203 and supported on the end wall of the second connecting body 2 near the third opening 203, so that one end of the first elastic element 42 abuts against the first limiting head 412 and the other end abuts against the overlap portion 52. Thus, the first elastic element 42 is elastically supported on the second connecting body 2 through the overlap 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 the first elastic element 42 and the second connecting body 2 being in rigid contact for a long time, and reducing the probability of failure of the elastic characteristics of the first elastic element 42.

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

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

[0069] Furthermore, refer to Figure 2 , Figure 5 , Figure 6 and Figure 9 As shown, in some embodiments, the second connecting body 2 has a first limiting through hole 204 on the opposite side wall near the second opening 202; the connecting assembly 3 includes: a connecting shaft 31 having a second rod 311 and a second limiting head 312; the second rod 311 passes through the first opening 102 and the second opening 202 into the first receiving chamber 101 and the second receiving chamber 201, and the second rod 311 has a first insertion hole 313; the second limiting head 312 is located in the first receiving 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 311 is limited and fixed in the first receiving chamber 101 by the second limiting head 312; the first limiting pin 32 is inserted and pulled through the first limiting through hole 204 and the first insertion hole 313 to limit and fix the second rod 311 in the second receiving chamber 201.

[0070] Specifically, in the technical solution adopted in this 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 receiving 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 has a long strip structure and can pass through the first opening 102 and the second opening 202 into the first receiving chamber 101 and the second receiving chamber 201. The second limiting head 312 is disposed at the end of the second rod body 311 and is located in the first receiving chamber 101. Since the size of the second limiting head 312 is larger than the first opening 102, from... The second limiting head 312 can prevent the second rod 311 from moving out of the first receiving chamber 101 through the first opening 102. A first insertion hole 313 is provided on the second rod 311 and located in the second receiving chamber 201, so that the first insertion hole 313 can coincide with the first limiting through hole 204. The first limiting pin 32 passes through both the first limiting through hole 204 and the first insertion hole 313, thereby preventing the second rod 311 from moving out of the second receiving chamber 201 through the second opening 202. When it is necessary to disassemble the connecting shaft 31 from the second connecting body 2, the first limiting pin 32 can be pulled out of the first limiting through hole 204, allowing the connecting shaft 31 to be pulled out of the second receiving chamber 201 from the second opening 202.

[0071] Furthermore, refer to Figure 10 As shown, in some embodiments, the connecting assembly 3 further includes: a second shaft sleeve 33, sleeved on the second rod 311 and located in the second receiving chamber 201, the second shaft sleeve 33 being supported between the second rod 311 and the inner sidewall of the second connecting body 2; the second shaft sleeve 33 is provided with a second insertion hole, and the second insertion hole coincides with the first insertion hole 313.

[0072] Specifically, in the technical solution adopted in this application, a second shaft sleeve 33 is fitted on the second rod 311 of the connecting shaft 31 so that when the second rod 311 passes through the second opening 202 into the second receiving chamber 201, the second shaft sleeve 33 can fill the installation gap between the second rod 311 and the second connecting body 2, thereby preventing the second rod 311 from shaking in the second receiving chamber 201, so that the connection between the second rod 311 and the second connecting body 2 is more stable. In one embodiment, the second shaft assembly 33 can be made of a flexible material, such as rubber, so that when the second shaft assembly 33 is pressed between the inner wall and the side wall of the second rod 311 and the second connecting body, the second shaft assembly 33 can be flexibly deformed. This not only fills the installation gap between the second rod 311 and the second connecting body 2 with a higher degree of fit, but also transforms the rigid contact between the second rod 311 and the second connecting body 2 into a flexible contact. This effectively avoids irreversible damage caused by the rigid contact between the second rod 311 and the second connecting body 2 during long-term use, and significantly improves the service life of the elastic load-bearing device proposed in this application.

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

[0074] Specifically, in the technical solution adopted in this application, since one end of the second rod 311 is fixed in the second receiving chamber 201 by the second limiting head 312, and there is no restriction on the rotation of the second rod 311 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 7 is also arranged in the first receiving chamber 101, so that the connecting shaft 31 can rotate through the bearing 7. The bearing 7 can be an existing thrust ball bearing, which is arranged on the side wall of the first opening 102 in the second receiving chamber 201, and the bearing 7 is sleeved on the second rod 311 of the connecting shaft 31. The second rod 311 can rotate based on the first connecting body 1 through the bearing 7, which effectively reduces the friction between the second rod 311 and the first connecting body 1 when rotating.

[0075] Reference Figure 3As shown, in one embodiment, in order to facilitate the disassembly and separation of the connecting shaft 31 from the first connecting body 1, an installation port 105 can be provided on the first connecting body 1, located on the side wall adjacent to the first opening 102, and the installation port 105 communicates with the first opening 102. An installation cover 13 is also provided on the installation port 105. The installation cover 13 can be detachably configured on the installation port 105 by fastening screws. When it is necessary to assemble or disassemble the connecting shaft 31 and the bearing 7, the fastening screws can be unscrewed to remove the installation cover 13 from the installation port 105, so that the connecting shaft 31 and the bearing 7 can be installed, removed or replaced through the installation port 105.

[0076] Furthermore, 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 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 passes through the second limiting through hole 104; a connecting plate 9, which has 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 the suspension rope; 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 this 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 on the top of the first connecting body 1, specifically on the end face of the first connecting body away from the second connecting body. 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 laterally. 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. 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 suspension rope, while 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] Furthermore, refer to Figure 2 , Figure 11 and Figure 12As shown, in some embodiments, it further includes: a stop 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 stop 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 segment 801 and a second pin segment 802, the size of the first pin segment 801 being smaller than the size of the second pin segment 802; the connecting plate 9 is provided with a limiting connection port 903 communicating with the second connecting hole 902, the size of the limiting connection port 903 being larger than the size of the first pin segment 801 and smaller than the size of the second pin segment 802.

[0079] Specifically, in the technical solution adopted in this application, the abutting component 10 can be a headless screw, which is detachably installed at 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, thereby enabling the second elastic element 11 to be disposed between the second limiting pin 8 and the abutting component 10, and the second elastic element 11 is elastically supported between the second limiting pin 8 and the abutting component 10. In this embodiment, two different stop segments can be set on the second limiting pin 8, namely a first pin segment 801 and a second pin segment 802. The size of the first pin segment 801 is smaller than the size of the second pin segment 802. The connecting plate 9 is provided with a limiting connection port 903 that connects to the second connecting hole 902. Thus, by switching the first pin segment 801 and the second pin segment 802 on the second limiting pin 8, it can be controlled whether the second limiting pin 8 needs to pass through the limiting connection port 903 to enter or exit the second connecting hole 902. Specifically, the size of the limiting connection port is set to be larger than the first pin segment 801 and smaller than the second pin segment 802. In use, due to the elastic support of the second elastic element 11 between the second limiting pin 8 and the abutting component 10, the second limiting pin 8 is normally positioned with the second pin segment 802 in the mounting slot 103. When the second limiting pin 8 is driven to slide in the second limiting through hole 104, the second elastic element 11 is compressed to store elastic energy, so that the second pin segment 802 in the mounting slot 103 becomes the first pin segment 801. At this time, the connecting plate 9 can be inserted into the mounting slot 103, and the second connecting hole 902 is sleeved on the first pin segment 801 through the limiting connection port 903, releasing the stored elastic energy of the second elastic element 11, so that the second limiting pin 8 returns to its original position, thereby switching the first pin segment 801 in the mounting slot 103 to the second pin segment 802. Since the size of the second pin segment 802 is larger than the size of the limiting connection port 903, the connecting plate 9 is fixed in the mounting slot 103. If it is necessary to disassemble the connecting plate 9, press the end of the second limiting pin 8 away from the abutting component 10, so that the second limiting pin 8 slides in the second limiting through hole 104, thereby switching the second pin segment 802 in the mounting slot 103 to the first pin segment 801, so that the connecting plate 9 can be taken out from the mounting slot 103 by passing through the first pin segment 801 through the limiting connection port 903.

[0080] Furthermore, refer to Figure 2 , Figure 4 and Figure 11As shown, in some embodiments, it further includes: a keycap 12, sleeved on the end of the second limiting pin 8 away from the second elastic element 11; the second limiting through hole 104 has a first through section 104a and a second through section 104b; the diameter of the first through section 104a is larger than the size of the keycap 12, so that the keycap 12 can slide through the second limiting pin 8 in the first through section 104a; the diameter of the second through section 104b is smaller than the size of the keycap 12, so that the maximum sliding distance of the second limiting pin 8 in the second limiting through hole 104 is limited by the keycap 12 and the second through section 104b.

[0081] Specifically, in the technical solution adopted in this application, a keycap 12 can be configured at the end of the second limiting pin 8 to characterize the key position on the first connecting body 1 for easy manual operation. The keycap 12 also increases the contact area with the human body, reducing the pressure exerted on the body and alleviating discomfort when pressing the key. In this embodiment, to avoid excessive compression of the second elastic element 11 when switching between the first pin segment 801 and the second pin segment 802 by driving the second limiting pin 8 to slide, the second limiting through hole 104 can be configured to consist of a first through hole segment 104a and a second through hole segment 104b. The first through hole segment 104a can cooperate with the sliding of the keycap 12, so the diameter of the first through hole segment 104a is larger than the size of the keycap 12, while the second through hole segment 104b is used to restrict the sliding of the keycap 12. The second perforated section 104b is positioned on the side of the first perforated section 104a close to the second elastic element 11, and the diameter of the second perforated section 104b is smaller than the size of the keycap 12. This allows the second perforated section 104b to limit the maximum sliding distance of the keycap 12 in the second limiting through hole 104. After the keycap 12 is installed at the end of the second limiting pin 8, the cooperation between the keycap 12 and the second perforated section 104b can effectively prevent the second limiting pin 8 from excessively compressing the second elastic element 11.
