Description

Technical Field

[0001] This application belongs to the field of fitness equipment, specifically relating to a treadmill. Background Technology

[0002] A treadmill is available where users exercise and recover by running on it. The treadmill includes a base and a running track. It also includes handrails installed on both sides of the running track to provide support and balance, preventing falls during running. To ensure adequate protection, the handrails typically extend along the length of the running track, allowing users to grip them. However, this design only provides protection to the sides of the track. Users are not protected when starting the treadmill at the front of the track, and they are also unprotected when leaving the treadmill at the rear.

[0003] Existing handrail structures are typically fixed directly to the base as a whole, resulting in a large space requirement during transportation and making them susceptible to damage from collisions or compression during handling. Furthermore, because the handrail structure needs precise alignment with the treadmill's main structure, it demands ample installation space and tools. Its overall weight also makes installation impossible for a single person, requiring multiple people to assist, increasing labor and time costs. Moreover, any misalignment during installation is more complicated to adjust, leading to delays and reduced installation quality. Finally, subsequent maintenance of the treadmill often necessitates replacing the entire handrail structure, significantly increasing repair costs. Utility Model Content

[0004] This application provides a treadmill to solve the technical problems of existing treadmills having handrail structures that are inconvenient to transport, difficult to install and maintain, and have a small protective range.

[0005] The technical solution adopted in this application is as follows:

[0006] A treadmill includes a main body and handrail structures. The main body includes a base, a column, and a running track disposed on the base. The column is disposed on the base and located in front of the running track. A handrail structure is disposed on each of the left and right sides of the running track. The handrail structure includes a guide section handrail detachably disposed on the column and a descent section handrail detachably disposed on the base. The handrail structure also includes a transition section handrail. One of the guide section handrail and the transition section handrail is provided with a connector, and the other is provided with a mounting hole for the connector. One of the descent section handrail and the transition section handrail is provided with a connector, and the other is provided with a mounting hole for the connector. The transition section handrail is detachably disposed on the guide section handrail and the descent section handrail via the connector.

[0007] The treadmill in this application also includes the following additional technical features:

[0008] The connector is provided on the guide section handrail and the deceleration section handrail. The guide section handrail and the deceleration section handrail are provided with receiving holes. The connector includes a fixed section provided in the receiving hole and a connecting section that is at least partially exposed in the receiving hole. The mounting hole is sleeved on the connecting section.

[0009] The connector has multiple positioning holes spaced apart along the circumference of the connecting section. The positioning holes are provided with internal threads. The transition section handrail is provided with fixing holes that mate with the positioning holes. The fixing holes are connected to the mounting holes. The handrail structure also includes a locking component that passes through the fixing holes and is threadedly connected to the positioning holes.

[0010] The guide handrail includes a stable section connected to the column and an adapter section. The adapter section bends and extends from the stable section toward the side away from the column and toward the side of the column closer to the track. The adapter section is equipped with a connector, the stable section is equipped with a mounting piece, the mounting piece is equipped with a threaded hole, and the column is equipped with a positioning bolt that mates with the threaded hole.

[0011] The stabilizing section is provided with assembly holes, and the mounting parts are fixed in the assembly holes.

[0012] The base includes a side plate facing the side of the runway away from the uprights. The descent section handrail includes a fastening section connected to the side plate and an assembly section with connecting parts. The fastening section has mounting parts with threaded holes, and the side plate has positioning bolts that mate with the threaded holes.

[0013] The guide section handrail includes a stable section connected to the upright and an adapter section. The adapter section extends from the stable section toward the side away from the upright and toward the side of the upright closer to the track. The adapter section is equipped with a connector. The transition section handrail extends along the direction of movement of the track. The track is equipped with a bearing surface to support the user. The vertical projection of the transition section handrail is in the bearing surface. The assembly section is connected to the transition section handrail. The descent section handrail also includes an inclined section that connects the fastening section and the assembly section. The axis of the inclined section has an angle α with the bearing surface, where α satisfies: 40°≤α≤80°.

[0014] The treadmill includes an emergency stop assembly, which includes a mounting structure and an emergency stop switch disposed within the mounting structure. The mounting structure has assembly holes that fit over the guide section handrail and the descent section handrail.

[0015] The mounting structure includes an upper fastener and a lower fastener. The upper fastener has a receiving hole for installing an emergency stop switch, and the upper fastener and the lower fastener are detachably connected.

[0016] The lower fastener is provided with a positioning element, which has a fastening hole. The fastening hole extends toward the side opposite to the upper fastener and protrudes from the outer surface of the positioning element. The end of the positioning element facing the upper fastener is also provided with a through hole that communicates with the fastening hole. The mounting structure also includes a fixing element. The upper fastener is provided with a mating element that cooperates with the fixing element. The fixing element passes through the through hole and mates with the mating element to connect the upper fastener and the lower fastener. The guide section handrail and the deceleration section handrail are also provided with a clearance positioning element, an emergency stop switch, and a clearance hole for the mating element.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. This application achieves a segmented handrail structure by detachably mounting the guide section handrail to the uprights, detachably mounting the deceleration section handrail to the base, and detachably mounting the transition section handrail to both the guide and deceleration sections via connectors. This allows for separate transportation and installation of the guide, deceleration, and transition sections, improving installation and transportation efficiency, reducing space occupied during transport, and effectively lowering the probability of collisions. During use, each section can be individually repaired and replaced, reducing maintenance costs and improving efficiency. Furthermore, with the handrail structure positioned on both sides of the runway and the guide section handrail connected to the uprights, both provide forward protection for users. This handrail structure protects users from the front and sides, expanding its protective range.

[0019] 2. As a preferred embodiment of this application, by providing a connecting member including a fixing section disposed in the receiving hole, the impact on the exterior of the handrail structure is reduced, maintaining the overall appearance of the handrail structure as simple and smooth as possible, facilitating the user's grip, and improving the smoothness of hand movement on the handrail structure during treadmill exercise. The receiving hole facilitates the installation and positioning of the connecting member. Simultaneously, by providing a connecting section, with the mounting hole fitting within the connecting section, the installation and positioning of the transition section handrail is facilitated.

[0020] Furthermore, by setting multiple positioning holes at intervals along the circumference of the connecting section, the locking component passes through the fixing hole set in the transition section handrail and is threadedly connected to the positioning hole. The locking component fixes the transition section handrail and the connecting section from multiple directions, ensuring a stable connection between the transition section handrail and the connecting section and improving the overall structural strength of the handrail structure.

[0021] 3. As a preferred embodiment of this application, by setting the adapting section to bend and extend towards the side away from the column and towards the side of the column closer to the runway, the adapting section better adapts to the spatial layout of the runway and the movement path of the users. When the user is at the front of the runway, they can more naturally and comfortably grasp the guide section handrail. The guide section can play a better guiding and protective role. As the user moves backward relative to the runway, the user can accurately move along the guide section handrail to the transition section handrail, improving the user experience. The handrail structure can continuously provide support during the user's movement. The guide section handrail is equipped with a stabilizing section connected to the column. The stabilizing section has a mounting component. The positioning bolt on the column and the threaded hole of the mounting component cooperate. The cooperation between the positioning bolt and the threaded hole provides a reliable mechanical connection, ensuring a stable connection between the fixed section and the column. This allows the guide section handrail to withstand greater tensile, compressive, and shear forces, ensuring that the guide section handrail will not easily shake or fall off during use, providing safe and reliable support for the user.

[0022] Furthermore, by setting assembly holes, installation positions are provided for the mounting components. The mounting components are placed inside the assembly holes to avoid exposure. On the one hand, this protects the mounting components and the connection position between the mounting components and the positioning bolts, preventing collisions and corrosion. On the other hand, placing the mounting components in the assembly holes reduces the impact on the outer surface of the guide section handrail, ensuring that the guide section handrail is easy for users to grip.

[0023] 4. In a preferred embodiment of this application, by setting the base to include a side plate facing the side of the runway away from the uprights, and the descent handrail including a fixed section connected to the side plate and an assembly section with connecting parts, the protection range of the descent handrail covers the side of the runway away from the uprights, expanding the protection range of the handrail structure. By setting the mounting parts, which have threaded holes, and the side plate having positioning bolts that mate with the threaded holes, the engagement of the positioning bolts and the threaded holes provides a reliable mechanical connection, ensuring a stable connection between the fastening section and the side plate. This allows the descent handrail to withstand greater tensile, compressive, and shear forces, ensuring that the descent handrail will not easily shake or fall off during use, providing safe and reliable support for users.

[0024] 5. As a preferred embodiment of this application, by setting the self-stabilizing section of the adapting section to curve and extend towards the side away from the column and towards the side closer to the runway, the adapting section is made more adaptable to the spatial layout of the runway and the movement path of the users. This allows users to grip the guide section handrail more naturally and comfortably when they are at the front of the runway. The guide section can play a better guiding and protective role. As the users move backward relative to the runway, they can accurately move along the guide section handrail to the transition section handrail. The transition section handrail extends along the movement direction of the runway. The vertical projection of the transition section handrail onto the bearing surface is also a good guide, helping users to better maintain direction and rhythm. By setting the inclined section, the handrail provides tilt guidance for users. Users can enter or leave the runway through the inclined section, thus improving the protection range of the handrail structure. By setting α, the tilt angle of the inclined section is optimized, making it easier for users to hold and improving the guiding effect of the inclined section.

[0025] 6. As a preferred embodiment of this application, by setting an emergency stop component, the emergency stop component includes an installation structure with assembly holes. The assembly holes are fitted onto the guide section handrail and the slow descent section handrail, making it easier for the user's hand to touch the emergency stop switch, so as to stop the treadmill in an emergency. At the same time, the emergency stop switch on the corresponding path can be triggered when the user moves forward or backward relative to the treadmill, thereby improving the safety effect of the treadmill.

[0026] Furthermore, by setting upper and lower fasteners, installation and disassembly are facilitated. The upper and lower fasteners are detachable, simplifying the installation process of the emergency stop switch. During installation, the emergency stop switch can be first placed in the receiving hole of the upper fastener, and then the upper and lower fasteners are connected, improving the installation efficiency of the emergency stop switch. It also facilitates the disassembly of the emergency stop switch, improving maintenance efficiency and reducing maintenance costs. The receiving hole in the upper fastener provides precise positioning for the emergency stop switch, ensuring the accuracy of the installation position. After the upper and lower fasteners are connected, they provide a stable support structure for the emergency stop switch, ensuring that the emergency stop switch is always in a reliable working state. This achieves modular installation of the emergency stop component, improving its applicability.

[0027] 7. In a preferred embodiment of this application, fastening holes provide precise installation positioning for the fasteners, ensuring accurate alignment of the upper and lower fasteners during connection. The fasteners pass through the fastening holes and through-holes to engage with the mating parts, tightly connecting the upper and lower fasteners together. This ensures a tight connection between the installation structure and the guide and descent sections of the handrail, improving the overall strength of the installation structure and providing stable support for the emergency stop switch. The guide and descent sections of the handrail are equipped with clearance holes to effectively avoid interference with the positioning, emergency stop switch, and mating parts, making the spatial layout of the entire installation structure and handrail more rational, preventing mutual interference, and ensuring the compactness and aesthetics of the overall structure.

[0051] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0052] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below. It should be noted that, unless otherwise specified, the embodiments of this application and the features thereof can be combined with each other.

[0053] like Figure 1 , Figure 2 , Figure 3 As shown, a treadmill includes a main body 1 and a handrail structure 2. The main body 1 includes a base 11, a column 12, and a running track 13 disposed on the base 11. The column 12 is disposed on the base 11 and located in front of the running track 13. A handrail structure 2 is disposed on each of the left and right sides of the running track 13. The handrail structure 2 includes a guide section handrail 21 detachably disposed on the column 12 and a deceleration section handrail 23 detachably disposed on the base 11. The handrail structure 2 also includes a transition section handrail 22. One of the guide section handrail 21 and the transition section handrail 22 is provided with a connector 24, and the other is provided with a mounting hole 25 for the connector 24. One of the deceleration section handrail 23 and the transition section handrail 22 is provided with a connector 24, and the other is provided with a mounting hole 25 for the connector 24. The transition section handrail 22 is detachably disposed on the guide section handrail 21 and the deceleration section handrail 23 through the connector 24.

[0054] This application achieves segmented handrail structure 2 by setting the guide section handrail 21 detachably mounted on the column 12, the deceleration section handrail 23 detachably mounted on the base 11, and the transition section handrail 22 detachably mounted on the guide section handrail 21 and the deceleration section handrail 23 via connector 24. This allows the guide section handrail 21, the deceleration section handrail 23, and the transition section handrail 22 to be transported and installed independently, improving the installation and transportation efficiency of the handrail structure 2, reducing the space occupied by the handrail structure 2 during transportation, and effectively reducing the probability of collision during transportation. During use, the guide section handrail 21, the deceleration section handrail 23, and the transition section handrail 22 can all be repaired and replaced individually, reducing later maintenance costs and improving maintenance efficiency. Meanwhile, the handrail structure 2 is set on both sides of the runway 13, and the guide section handrail 21 is connected to the column 12. The guide section handrail 21 and the column 12 can provide front protection for users. The handrail structure 2 of this application can protect the front and sides of users, expanding the protection range of the handrail structure 2.

[0055] In this application, the connector 24 can be configured in any of the following embodiments:

[0056] Implementation method one: such as Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 15 As shown, the connector 24 is disposed on the guide section handrail 21 and the slow-descent section handrail 23. Both the guide section handrail 21 and the slow-descent section handrail 23 have receiving holes 26. The connector 24 includes a fixing section 241 disposed within the receiving hole 26 and a connecting section 242 at least partially exposed within the receiving hole 26. A mounting hole 25 is fitted onto the connecting section 242. By including the fixing section 241 within the receiving hole 26 in the connector 24, the impact on the exterior of the handrail structure 2 is reduced, maintaining the overall appearance of the handrail structure 2 as simple and smooth as possible, facilitating grip by users, and improving the smoothness of hand movement on the handrail structure 2 during treadmill exercise. The receiving hole 26 facilitates the installation and positioning of the connector 24. Simultaneously, by providing the connecting section 242 and fitting the mounting hole 25 onto it, the installation and positioning of the transition section handrail 22 are facilitated.

[0057] Implementation Method 2: This implementation method 2 is not illustrated. The difference from implementation method 1 is that the connecting member is provided on the transition section handrail, and the transition section handrail is provided with a receiving hole.

[0058] Implementation Method 3: This implementation method 3 is not illustrated. The difference from implementation method 1 is that the connecting member is provided on the transition section handrail and the guide section handrail, and the transition section handrail and the guide section handrail are provided with receiving holes; or, the connecting member is provided on the transition section handrail and the slow descent section handrail, and the transition section handrail and the slow descent section handrail are provided with receiving holes.

[0059] Those skilled in the art will understand that the fixing section 241 can be installed in the receiving hole 26 by welding, snap-fitting, or by providing threads on the fixing section 241 and internal threads on the receiving hole 26, with the fixing section 241 and the receiving hole 26 being threaded together, etc., which are not limited in this application. Furthermore, the method of forming the mounting hole 25 and the receiving hole 26 is not limited in this application. The guide section handrail 21, the deceleration section handrail 23, and the transition section handrail 22 can be hollow structures to form the mounting hole 25 and the receiving hole 26, or the guide section handrail 21, the deceleration section handrail 23, and the transition section handrail 22 can be solid structures, with the mounting hole 25 and the receiving hole 26 machined by cutting or other processes.

[0060] In embodiment one, the connection configuration of connector 24 can be any of the following embodiments:

[0061] Example 1: As Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 12As shown, the connector 24 has multiple positioning holes 243 spaced apart circumferentially along the connecting section 242. The positioning holes 243 are provided with internal threads (not shown in the attached figure). The transition section handrail 22 is provided with fixing holes 221 that mate with the positioning holes 243. The fixing holes 221 communicate with the mounting holes 25. The handrail structure 2 also includes a locking member 27, which passes through the fixing holes 221 and is threadedly connected to the positioning holes 243. By setting multiple positioning holes 243 spaced apart circumferentially along the connecting section 242, and by threading the locking member 27 through the fixing holes 221 and the positioning holes 243 in the transition section handrail 22, the locking member 27 fixes the transition section handrail 22 and the connecting section 242 from multiple directions, ensuring a stable connection between the transition section handrail 22 and the connecting section 242, and improving the overall structural strength of the handrail structure 2.

[0062] Example 2: This example 2 is not shown in the figure. The connecting section is provided with external threads in the circumference and the mounting hole is provided with internal threads. The connecting section is threadedly connected to the mounting hole.

[0063] Those skilled in the art will understand that the connecting section 242 may also be provided with a telescopic component, and the wall of the mounting hole 25 may be provided with a limiting hole, so that the telescopic component and the limiting hole cooperate to achieve the connection between the connecting section 242 and the mounting hole 25.

[0064] In this application, the guide handrail 21 can be configured in any of the following embodiments:

[0065] Implementation Method Four: (e.g.) Figure 1 , Figure 4 , Figure 5 , Figure 9 , Figure 11 As shown, the guide handrail 21 includes a stabilizing section 211 connected to the column 12 and an adapting section 213. The adapting section 213 extends from the stabilizing section 211 toward the side away from the column 12 and toward the side of the column 12 closer to the track 13. The adapting section 213 is provided with a connector 24. The stabilizing section 211 is provided with a mounting part 212. The mounting part 212 is provided with a threaded hole 2121. The column 12 is provided with a positioning bolt 121 that mates with the threaded hole 2121.

[0066] By setting the adapter section 213 and the self-stabilizing section 211 to bend and extend towards the side away from the column 12 and towards the side of the column 12 closer to the runway 13, the adapter section 213 is more adapted to the spatial layout of the runway 13 and the movement path of the user. When the user is at the front of the runway 13, he / she can more naturally and comfortably grasp the guide section handrail 21. The guide section can play a better guiding and protective role. As the user moves backward relative to the runway 13, the user can accurately move along the guide section handrail 21 to the transition section handrail 22, which improves the user experience. The handrail structure 2 can continuously provide support during the movement of the user. The guide handrail 21 is equipped with a stabilizing section 211 connected to the column 12. The stabilizing section 211 is equipped with a mounting part 212. The positioning bolt 121 on the column 12 cooperates with the threaded hole 2121 of the mounting part 212. The cooperation between the positioning bolt 121 and the threaded hole 2121 provides a reliable mechanical connection, ensuring a stable connection between the fixed section 241 and the column 12. This allows the guide handrail 21 to withstand greater tensile, compressive, and shear forces, ensuring that the guide handrail 21 will not easily shake or fall off during use, and providing safe and reliable support for users.

[0067] Implementation Method 5: This implementation method 5 is not illustrated. The difference from implementation method 4 is that the column is provided with mounting parts, the stabilizing section has a side facing the column, and the positioning bolts are provided on the side.

[0068] As a preferred embodiment of implementation method four: such as Figure 1 , Figure 4 , Figure 5 , Figure 9 , Figure 11 As shown, the stabilizing section 211 is provided with an assembly hole 2111, and the mounting component 212 is fixed in the assembly hole 2111. Furthermore, the positioning bolt 121 on the column 12 engages with the threaded hole 2121 to connect the column 12 and the stabilizing section 211, with the stabilizing section 211 abutting against the column 12. The assembly hole 2111 provides an installation position for the mounting component 212. The mounting component 212 is positioned within the assembly hole 2111, preventing it from being exposed. This protects the mounting component 212 and the connection point between it and the positioning bolt 121, preventing collisions and corrosion. Furthermore, the mounting component 212's placement within the assembly hole 2111 reduces the impact on the outer surface of the guide section handrail 21, ensuring that the guide section handrail 21 is easy for users to grip.

[0069] In this application, the connection between the descent section handrail 23 and the base 11 can be any of the following embodiments:

[0070] Implementation method six: such as Figure 1 , Figure 4 , Figure 6 , Figure 14 , Figure 15 As shown, the base 11 includes a side plate 111 facing the side of the runway 13 away from the column 12. The descent section handrail 23 includes a fastening section 231 connected to the side plate 111 and an assembly section 232 with a connector 24. The fastening section 231 is provided with an installation part 212, and the installation part 212 is provided with a threaded hole 2121. The side plate 111 is provided with a positioning bolt 121 that mates with the threaded hole 2121.

[0071] By setting the base 11 to include a side plate 111 facing the side of the runway 13 away from the column 12, and the descent handrail 23 including a fixed section 241 connected to the side plate 111 and an assembly section 232 with a connector 24, the protection range of the descent handrail 23 covers the side of the runway 13 away from the column 12, thus expanding the protection range of the handrail structure 2. By setting the mounting component 212, which has a threaded hole 2121, and the side plate 111 having a positioning bolt 121 that mates with the threaded hole 2121, the engagement of the positioning bolt 121 and the threaded hole 2121 provides a reliable mechanical connection, ensuring a stable connection between the fastening section 231 and the side plate 111. This allows the descent handrail 23 to withstand greater tensile, compressive, and shear forces, ensuring that the descent handrail 23 will not easily shake or fall off during use, providing safe and reliable support for users.

[0072] Implementation Method Seven: This Implementation Method Seven is not illustrated. The difference from Implementation Method Six is ​​that the mounting component is located on the side plate, and the fastening section is equipped with positioning bolts.

[0073] As a preferred embodiment 4 under embodiments six and seven: Figure 1 , Figure 9 , Figure 11 , Figure 14 As shown, the guide section handrail 21 includes a stabilizing section 211 connected to the column 12 and an adapting section 213. The adapting section 213 extends from the stabilizing section 211 toward the side away from the column 12 and toward the side of the column 12 closer to the track 13. The adapting section 213 is provided with a connector 24. The transition section handrail 22 extends along the movement direction of the track 13. The track 13 is provided with a bearing surface 131 for supporting users. The vertical projection of the transition section handrail 22 is within the bearing surface 131. The assembly section 232 is connected to the transition section handrail 22. The descent section handrail 23 also includes an inclined section 233 connecting the fastening section 231 and the assembly section 232. The axis of the inclined section 233 has an angle α with the bearing surface 131, where α satisfies: 40°≤α≤80°. Preferably, when 50°≤α≤75°, the transition section handrail 23 can be optimized. Figure 1 The length in the horizontal direction is such that before the user enters the end of the runway 13, the change in hand sensation caused by holding the inclined section 233 reminds the user to pay attention to their position on the runway 13.

[0074] By setting the adapter section 213 to bend and extend towards the side away from the column 12 and towards the side closer to the runway 13, the adapter section 213 is made more adaptable to the spatial layout of the runway 13 and the movement path of the users. This allows users to more naturally and comfortably grasp the guide section handrail 21 when they are at the front of the runway 13. The guide section can play a better guiding and protective role. As the user moves backward relative to the runway 13, the user can accurately move along the guide section handrail 21 to the transition section handrail 22. The transition section handrail 22 extends along the movement direction of the runway 13, and the vertical projection of the transition section handrail 22 is projected onto the bearing surface 131. The handrail 22 extends along the direction of movement of the track 13, providing reliable support and protection for personnel moving along the track 13. The extension direction of the transition handrail 22 is consistent with the direction of movement of the track 13, and it also plays a good guiding role, helping personnel to better maintain direction and rhythm. By setting the inclined section 233, it provides tilt guidance for users. Users can enter or leave the track 13 through the guidance of the inclined section 233, thereby increasing the protection range of the handrail structure 2. By setting α, the tilt angle of the inclined section 233 is optimized, making the inclined section 233 easier for users to hold and improving the guiding effect of the inclined section 233.

[0075] In this application, the emergency braking device of the treadmill can be any of the following embodiments:

[0076] Implementation method eight: such as Figure 1 , Figure 2 , Figure 16 , Figure 17 , Figure 18 As shown, the treadmill includes an emergency stop component 3, which includes a mounting structure 31 and an emergency stop switch 32 disposed within the mounting structure 31. The mounting structure 31 has an assembly hole 311, which is fitted onto the guide section handrail 21 and the slow-descent section handrail 23. By providing the emergency stop component 3, including the mounting structure 31 with the assembly hole 311 fitted onto the guide section handrail 21 and the slow-descent section handrail 23, the user's hand can more easily touch the emergency stop switch 32, facilitating the stopping of the treadmill in an emergency. Furthermore, the user can trigger the emergency stop switch 32 along the corresponding path when moving forward or backward relative to the treadmill, improving the treadmill's safety performance.

[0077] Implementation Method Nine: This implementation method nine is not illustrated. The difference from implementation method eight is that the assembly hole is fitted onto the transition section handrail.

[0078] In embodiment eight, the mounting structure 31 can be configured in any of the following embodiments:

[0079] Example 5: Figure 1 , Figure 2 , Figure 16 , Figure 17 , Figure 18 As shown, the mounting structure 31 includes an upper fastener 312 and a lower fastener 313. The upper fastener 312 is provided with a receiving hole 3121 for mounting the emergency stop switch 32. The upper fastener 312 and the lower fastener 313 are detachably connected.

[0080] By providing upper fastener 312 and lower fastener 313, installation and disassembly are facilitated. The upper and lower fasteners 313 are detachably connected, simplifying the installation process of the emergency stop switch 32. During installation, the emergency stop switch 32 can be first placed in the receiving hole 3121 of the upper fastener 312, and then the upper and lower fasteners 313 can be connected, improving the installation efficiency of the emergency stop switch 32. It also facilitates the disassembly of the emergency stop switch 32, improving maintenance efficiency and reducing maintenance costs. The receiving hole 3121 in the upper fastener 312 provides precise positioning for the emergency stop switch 32, ensuring the accuracy of its installation position. After the upper fastener 312 and lower fastener 313 are connected, they provide a stable support structure for the emergency stop switch 32, ensuring that the emergency stop switch 32 is always in a reliable working state. This enables modular installation of the emergency stop assembly 3, improving its applicability.

[0081] As a preferred specific example 1 under embodiment 5, such as Figure 1 , Figure 2 , Figure 10 , Figure 16 , Figure 17 , Figure 18 As shown, the lower fastener 313 is provided with a positioning element 3131, which has a fastening hole 3132. The fastening hole 3132 extends towards the side opposite to the upper fastener 312 and protrudes from the outer surface of the positioning element 3131. The end of the positioning element 3131 facing the upper fastener 312 is also provided with a through hole (not shown in the figure) communicating with the fastening hole 3132. The mounting structure 31 also includes a fixing element 314. The upper fastener 312 is provided with a mating element 3122 that cooperates with the fixing element 314. The fixing element 314 passes through the through hole and cooperates with the mating element 3122 to connect the upper fastener 312 and the lower fastener 313. The guide section handrail 21 and the deceleration section handrail 23 are also provided with clearance holes 28 for the positioning element 3131, the emergency stop switch 32, and the mating element 3122. Furthermore, the connecting element 24 is also provided with clearance holes 28.

[0082] The fastening hole 3132 provides precise installation positioning for the fastener 314, ensuring accurate alignment of the upper fastener 312 and lower fastener 313 during connection. The fastener 314 passes through the fastening hole 3132 and the through hole to engage with the mating part 3122, tightly connecting the upper and lower fasteners 312 and ensuring a tight connection between the installation structure 31, the guide section handrail 21, and the deceleration section handrail 23. This improves the overall strength of the installation structure 31 and provides stable support for the emergency stop switch 32. The guide section handrail 21 and the deceleration section handrail 23 are equipped with clearance holes 28, effectively avoiding interference with the positioning part 3131, the emergency stop switch 32, and the mating part 3122. This makes the spatial layout of the entire installation structure 31 and the handrail more rational, preventing mutual interference and ensuring the compactness and aesthetics of the overall structure.

[0083] Example 6: This example 6 is not shown in the figure. The mounting structure is provided with receiving holes and the mounting structure is integrally formed.

[0084] In embodiment 5, the assembly hole 311 can be fitted in any of the following specific examples:

[0085] Specific example 2: such as Figure 16 , Figure 17 , Figure 18 As shown, the mounting structure 31 is symmetrically divided along its axial direction to form an upper fastener 312 and a lower fastener 313, each of which has a half-sized assembly hole 311. Furthermore, one end of the mating part 3122 extends toward the lower fastener and abuts against the positioning part 3131.

[0086] Specific Example 3: This specific example 3 is not illustrated. The assembly hole has an internal thread, and the deceleration section handrail and the guide section handrail have external threads. The installation structure is threadedly connected to the deceleration section handrail and the guide section handrail.

[0087] Specific Example 4: This specific example 4 is not illustrated. The wall of the assembly hole is provided with a telescopic component, and the handrails of the descent section and the guide section are provided with limiting holes. The assembly hole and the telescopic component cooperate to fix the installation structure to the handrails of the descent section and the guide section.

[0088] Specific Example 5: This specific example 5 is not illustrated. The difference from specific example 4 is that the handrail of the descent section and the handrail of the guide section are equipped with telescopic components, and the wall of the assembly hole is equipped with a limiting hole.
