Description

Technical Field

[0001] This invention relates to the field of escape equipment technology, and in particular to a gravity-based self-locking high-altitude escape device. Background Technology

[0002] High-altitude escape devices are key equipment in the safety systems of high-rise buildings, designed to provide people with a fast and reliable vertical escape route in emergencies such as fires and earthquakes. Existing technologies, such as the "High-Altitude Escape Device" disclosed in Chinese Patent CN201410305603.2, employ a gravity self-locking mechanism as the core safety component, achieving unlocking control through a brake handle and connecting pull rope or brake cable. Under normal operating conditions, the gravity self-locking mechanism automatically locks using mechanical principles to prevent accidental descent; when the user operates the brake handle, the pull rope or brake cable transmits the unlocking power to the self-locking structure, driving the unlocking lever to move, thereby releasing the lock and achieving controlled descent.

[0003] In actual use, the pull rope or brake rope may deform and elongate under tension, causing the unlocking force generated by the brake handle to be unable to be fully and effectively transmitted to the gravity self-locking structure. Specifically, the elongation of the rope absorbs some of the unlocking energy, making the actual movement distance of the unlocking lever insufficient to reach the stroke required for complete unlocking, thus causing the escape device to fail to properly unlock. This unlocking failure not only reduces the efficiency and reliability of escape but may also lead to personnel being stranded or losing control of the descent in high-altitude emergencies, posing serious safety risks. Therefore, we provide a gravity self-locking high-altitude escape device to solve the above problems. Summary of the Invention

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] like Figure 1 — Figure 12 The example shown.

[0042] A gravity-driven self-locking high-altitude escape device has a first direction. The escape device includes a bracket 100, a self-locking device 200, an unlocking drive assembly 300, and a transmission rod 400. It is understood that the power from the unlocking drive assembly 300 is transmitted to the unlocking end of the self-locking device 200 through the transmission rod 400, thereby realizing the transmission of force and unlocking. In this application, the power transmitted by the transmission rod 400 will not deform in the first direction, that is, it can completely drive the unlocking end of the self-locking device 200 to move, thereby realizing unlocking.

[0043] Specifically, the bracket 100 includes a first column 110 and a second column 120 arranged side by side and extending along a first direction. The self-locking device 200 includes a first self-locking component 210 and a second self-locking component 220. The unlocking end of the first self-locking component 210 is provided with a first unlocking component 201, and the unlocking end of the second self-locking component 220 is provided with a second unlocking component 202. The first self-locking component 210 is fixedly disposed on the first column 110 and slidably connected to the second column 120, and the second self-locking component 220 is fixedly disposed on the second column 120 and connected to the first column 110. The unlocking drive component 300 includes a first drive component 310 and a second drive component 320. The first drive component 310 is fixedly disposed on the first column 110, and the second drive component 320 is fixedly disposed on the second column 120. 0. The first drive assembly 310 has a first transmission assembly 311 at its drive end, and the second drive assembly 320 has a transmission device 321 at its drive end. A flexible shaft 301 is provided between the first transmission assembly 311 and the transmission device 321. The flexible shaft 301 is used for transmission between the first transmission assembly 311 and the transmission device 321. The transmission rod 400 includes a first rod body 410 and a second rod body 420. One end of the first rod body 410 is connected to the unlocking end of the first self-locking assembly 210, and the end of the first rod body 410 away from the first self-locking assembly 210 is connected to the first transmission assembly 311. One end of the second rod body 420 is connected to the unlocking end of the second self-locking assembly 220, and the end of the second rod body 420 away from the second self-locking assembly 220 is connected to the first transmission assembly 311.

[0044] In this embodiment, the first direction mentioned above is the vertical direction.

[0045] Please see Figure 1 and Figure 2 As shown in this embodiment, in order to enable vertical movement at high altitudes, the support 100 is designed as a split unit, consisting of a first column 110 and a second column 120. A first self-locking component 210, which is slidably connected to the second column 120, is fixedly installed on the first column 110. Correspondingly, a second self-locking component 220, which is slidably connected to the first column 110, is fixedly installed on the second column 120. The escape rope passes through the first self-locking component 210 and the second self-locking component 220 sequentially from top to bottom. Under the action of gravity, the first self-locking component 210 and the second self-locking component 220 lock the escape rope. If the first column 110 or the second column 120 is moved upwards, the first self-locking component 210 and the second self-locking component 220 will release the lock on the escape rope, thereby enabling upward climbing.

[0046] For example, the escape rope can be a steel wire rope or nylon rope, or any rope capable of bearing weight. The specific type and variety of rope are not limited here.

[0047] In this embodiment, if the escapee needs to escape downwards, the unlocking power is transmitted to the first rod 410 and the second rod 420 via the first drive component 310 or the second drive component 320, thereby transmitting the unlocking power to the first self-locking component 210 and the second self-locking component 220, simultaneously unlocking both components. Since the first drive component 310 transmits power to the first rod 410 via the first transmission component 311 to unlock the first column 110, and the second drive component 320 transmits power to the second rod 420 via the transmission device 321 to unlock the second column 120, and the first transmission component 311 and the transmission device 321 are connected by a flexible... The shaft 301 drives the device, so whether the unlocking is driven by the first drive assembly 310 or the second drive assembly 320, the unlocking force can be transmitted to the first rod 410 and the second rod 420 through the linkage of the first drive assembly 311, the flexible shaft 301 and the transmission device 321, so as to unlock the first self-locking assembly 210 and the second self-locking assembly 220 simultaneously. Therefore, the user does not need to use both hands to drive the first drive assembly 310 and the second drive assembly 320 to unlock the first self-locking assembly 210 and the second self-locking assembly 220. It can be understood that the advantage of this design is that it can be used for escape by people with disabilities who have only one arm, which greatly improves the practicality of the escape device and can be used for different people.

[0048] It should be noted that the flexible shaft 301 is a soft shaft, which can also transmit power when it undergoes a certain deformation. The length of the flexible shaft 301 should meet the height difference between the first column 110 and the second column 120 when climbing upwards.

[0049] In some embodiments, the first drive assembly 310 and the second drive assembly 320 have the same structure. The first drive assembly 310 includes a mounting bracket 3101. A drive rod 3102 and an unlocking drive gear 3103 are rotatably mounted on the mounting bracket 3101. The drive rod 3102 is provided with a sector tooth 3104 at the end facing the unlocking drive gear 3103. The sector tooth 3104 meshes with the unlocking drive gear 3103 for transmission. The shaft of the unlocking drive gear 3103 is connected to a first transmission shaft 3105. The first transmission shaft 3105 is connected to the first transmission assembly 311 for transmission.

[0050] Please see Figure 3 and Figure 4 As shown, both the drive rod 3102 and the unlocking drive gear 3103 are rotatably mounted on the mounting bracket 3101. The sector teeth 3104 at the end of the drive rod 3102 mesh with the unlocking drive gear 3103, meaning that when the drive rod 3102 rotates, the engagement of the sector teeth 3104 and the unlocking drive gear 3103 drives the unlocking drive gear 3103 to rotate. The unlocking drive gear 3103 then transmits power to the first transmission assembly 311 via the first transmission shaft 3105. The first transmission assembly then... 311 The unlocking power is then transmitted to the first self-locking component 210 via the first rod 410 and to the transmission device 321 via the flexible shaft 301. Finally, the transmission device 321 transmits the unlocking force from the first transmission component 311 to the second rod 420, and the second self-locking component 220 is unlocked via the second rod 420. Thus, through the linkage of various components, the first self-locking component 210 and the second self-locking component 220 are unlocked simultaneously via the first drive component 310.

[0051] Since the first drive component 310 and the second drive component 320 have the same structure, the working process of the second drive component 320 will not be described in detail here. You can refer to the working principle of the first drive component 310 described above.

[0052] In some embodiments, the first transmission assembly 311 includes a first fixed frame 3111, on which a first bevel tooth 3112 is rotatably mounted. The first bevel tooth 3112 is connected to the first rod body 410. A second bevel tooth 3113 and a third bevel tooth 3114 are rotatably mounted on the first fixed frame 3111 around the first bevel tooth 3112. The second bevel tooth 3113 and the third bevel tooth 3114 both mesh with the first bevel tooth 3112. The second bevel tooth 3113 is connected to the first transmission shaft 3105. The shaft of the third bevel tooth 3114 is connected to a first transmission joint 3115. The first transmission joint 3115 is connected to the flexible shaft 301.

[0053] Please see Figure 4 As shown, the first fixing frame 3111 is fixed on the mounting frame 3101. The first fixing frame 3111 is rotatably mounted with a second bevel tooth 3113 connected to the first drive shaft 3105 and a third bevel tooth 3114 connected to the first drive joint 3115. The first rod body 410 is rotatably connected to the first fixing frame 3111, and the first rod body 410 is provided with a first bevel tooth 3112. In this embodiment, the second bevel tooth 3113 and the third bevel tooth 3114 are both engaged with the first bevel tooth 3112. It can be understood that the rotational unlocking force from the first drive shaft 3105 can be transmitted to the first rod body 410 and to the first drive joint 3115 through the first bevel tooth 3112. Then, the unlocking force is transmitted to the flexible shaft 301 through the first drive joint 3115, thereby driving the second rod body 420 to rotate through the transmission device 321.

[0054] like Figure 6 As shown, it should be noted that the first transmission joint 3115 includes a first mounting shell 31151 and a second mounting shell 31152 that are perpendicularly connected to each other. A first joint shaft 31153 is rotatably mounted on the first mounting shell 31151. The end of the first joint shaft 31153 extends into the second mounting shell 31152, and the end of the first joint shaft 31153 facing away from the second mounting shell 31152 is connected to a third bevel tooth 3114. A second joint shaft 31155 is rotatably mounted on the second mounting shell 31152. The device is equipped with a second joint tooth 31156, which meshes with the first joint tooth 31154, and a second joint shaft 31155 is connected to the flexible shaft 301. It can be understood that the power from the third bevel tooth 3114 is transmitted to the flexible shaft 301 through the transmission chain composed of the first joint shaft 31153, the first joint tooth 31154, the second joint tooth 31156, and the second joint shaft 31155, thereby enabling the transmission device 321 to drive the second rod 420 to rotate and unlock the second self-locking component 220.

[0055] In this embodiment, both the first joint tooth 31154 and the second joint tooth 31156 are bevel gears.

[0056] In some embodiments, the transmission device 321 includes a second transmission component 3211 that is transmissionally connected to the second drive component 320. The second transmission component 3211 is transmissionally connected to the second rod 420. A third rod 3212 is provided on one side of the second rod 420 in the horizontal direction. A second transmission joint 3213 is provided between the third rod 3212 and the end of the second rod 420. The second transmission joint 3213 is used for transmission between the third rod 3212 and the second rod 420. A third transmission joint 3214 is provided on the third rod 3212. The third transmission joint 3214 is transmissionally connected to the flexible shaft 301.

[0057] Please see Figure 5 As shown, in order to achieve linkage between the first rod 410 and the second rod 420, a third rod 3212 is provided on one side of the second rod 420. The third transmission joint 3214 provided on the third rod 3212 is connected to the flexible shaft 301, so that the third rod 3212 can be driven to rotate by the first drive assembly 310. In order to transmit the unlocking force transmitted to the third rod 3212 to the second rod 420, a second transmission joint 3213 is provided between the top of the second rod 420 and the third rod 3212 for transmission connection, so as to realize the transmission of power from the first drive assembly 310 to the second rod 420.

[0058] Understandably, when it is necessary to unlock the first self-locking component 210 and the second self-locking component 220 through the second drive component 320, the power can also be transmitted to the second rod 420 through the second transmission component 3211, and then to the third rod 3212 through the second transmission joint 3213. Finally, the unlocking power of the third rod 3212 is transmitted to the flexible shaft 301 through the third transmission joint 3214, thereby also driving the first rod 410 to rotate and unlock, thus realizing the synchronous linkage between the first rod 410 and the second rod 420.

[0059] like Figure 7 As shown, in this embodiment, the third transmission joint 3214 includes a third mounting shell 32141 and a fourth mounting shell 32142 that are perpendicularly connected to each other. The third rod 3212 is rotatable relative to the third mounting shell 32141. A third joint tooth 32143 is provided on the third rod 3212. A third joint shaft 32144 is rotatably mounted on the fourth mounting shell 32142. A fourth joint tooth 32145 is installed at the end of the third joint shaft 32144, and the fourth joint tooth 32145 meshes with the third joint tooth 32143 for transmission.

[0060] In this embodiment, the second transmission joint 3213 can be formed by assembling two first transmission joints 3115, that is, a first transmission joint 3115 is installed on the top of the second rod 420 and the top of the third rod 3212. The two first transmission joints 3115 are connected by transmission to realize the direction conversion of the unlocking force.

[0061] In this embodiment, both the third joint tooth 32143 and the fourth joint tooth 32145 are bevel gears.

[0062] In some embodiments, the second transmission assembly 3211 includes a second fixed frame 32111, a second rod 420 rotatably connected to the second fixed frame 32111, a fourth bevel tooth 32112 rotatably disposed on the second fixed frame 32111, the shaft of the fourth bevel tooth 32112 being connected to the second drive assembly 320 for transmission, and a fifth bevel tooth 32113 disposed on the second rod 420, the fourth bevel tooth 32112 and the fifth bevel tooth 32113 engaging for transmission.

[0063] Please continue reading. Figure 5 As shown, by installing a fourth bevel gear 32112 that is connected to the second drive assembly 320 on the second fixed frame 32111 and a fifth bevel gear 32113 on the second rod 420, and then engaging the fourth bevel gear 32112 and the fifth bevel gear 32113, the power from the second drive assembly 320 can be transmitted to the second rod 420.

[0064] In some embodiments, a third transmission assembly 411 is further provided at the end of the first rod 410, and the third transmission assembly 411 is operatively connected to the unlocking end of the first self-locking assembly 210. A fourth transmission assembly 421 is further provided at the end of the second rod 420, and the fourth transmission assembly 421 is operatively connected to the unlocking end of the second self-locking assembly 220. The third transmission assembly 411 and the fourth transmission assembly 421 have the same structure. The third transmission assembly 411 includes a third fixing frame 4111. A sixth bevel tooth 4112 is provided on the first rod 410, and a seventh bevel tooth 4113 is rotatably provided on the third fixing frame 4111. The sixth bevel tooth 4112 and the seventh bevel tooth 4113 are meshed and connected. The rotating shaft of the seventh bevel tooth 4113 is operatively connected to the first unlocking assembly 201.

[0065] Please see Figure 1 , Figure 2 as well as Figure 3 As shown, the third transmission component 411 and the fourth transmission component 421 have the same structure and the same principle. Therefore, the third transmission component 411 will be used as an example here.

[0066] like Figure 8As shown, the first rod 410 is rotatably mounted to the third fixed frame 4111. The seventh bevel tooth 4113 mounted on the third fixed frame 4111 meshes with the sixth bevel tooth 4112 on the first rod 410, which can transmit the power from the first rod 410 to the active gear set 2012 at the unlocking end of the first self-locking assembly 210.

[0067] In some embodiments, the first self-locking assembly 210 and the second self-locking assembly 220 have the same structure. Two first fixing back plates 212 and two second fixing plates 213 are spaced apart inside the housing 211. The two first fixing back plates 212 are arranged side by side and the two second fixing plates 213 are also arranged side by side. Each first fixing back plate 212 has at least one first inclined groove 2121 on its side facing the second fixing plate 213. Each second fixing plate 213 has at least one second inclined groove 2131 on its side facing the first fixing back plate 212. A first clamping shaft 2122 is provided in the first inclined groove 2121 on the same horizontal plane, and a second clamping shaft 2132 is provided in the second inclined groove 2131 on the same horizontal plane. An unlocking rod 214 is provided below the first clamping shaft 2122. A transmission plate 215 is connected between the end of the first clamping shaft 2122 and the end of the unlocking rod 214.

[0068] In this application, the first self-locking component 210 and the second self-locking component 220 have the same structure and the same principle of clamping and locking the escape rope. Therefore, the first self-locking component 210 and the first unlocking component 201 are used as examples for illustration.

[0069] Please see Figure 9 , Figure 10 as well as Figure 11 As shown, the housing 211 is divided into left and right parts, namely, the housing 211 is formed by assembling a left shell 211a and a right shell 211b. Correspondingly, two first fixing back plates 212 are fixedly installed on the left shell 211a at intervals, and two second fixing plates 213 are fixedly installed on the right shell 211b at intervals. At least one first inclined groove 2121 is formed on the side of each first fixing back plate 212 facing the second fixing plate 213. The first inclined groove 2121 is inclined from top to bottom. Correspondingly, a second inclined groove 2131 corresponding to the position of the first inclined groove 2121 is also formed on the side of the second fixing plate 213 facing the first fixing back plate 212. The second inclined groove 2131 is also inclined from top to bottom. Please continue reading. Figure 10 and Figure 11 As shown, a first clamping shaft 2122 is provided in the first inclined groove 2121, and a second clamping shaft 2132 is provided in the second inclined groove 2131. There is a certain gap between the first clamping shaft 2122 and the second clamping shaft 2132 at the same level, which allows the escape rope to pass through.

[0070] In this embodiment, in order to adjust the distance between the first clamping shaft 2122 and the second clamping shaft 2132 for unlocking, transmission plates 215 are installed at both ends of the first clamping shaft 2122, and an unlocking rod 214 is installed between the two transmission plates 215. The unlocking rod 214 is connected to the first unlocking component 201. The first unlocking component 201 drives the unlocking rod 214 to move downward, which in turn drives the transmission plates 215 and the first clamping shaft 2122 to move downward in the first inclined groove 2121. Since the first inclined groove 2121 is inclined, the first clamping shaft 2122 will gradually move away from the second clamping shaft 2132 as it moves downward along the trajectory of the first inclined groove 2121, thereby increasing the distance between the first clamping shaft 2122 and the second clamping shaft 2132, thereby releasing the clamping state of the escape rope and achieving unlocking.

[0071] Please continue reading. Figure 10 and Figure 11 As shown, since both the first inclined groove 2121 and the second inclined groove 2131 are inclined grooves, and an escape rope is provided between the first clamping shaft 2122 and the second clamping shaft 2132, under the action of gravity, the entire shell 211 will drive the first fixed back plate 212 and the second fixed plate 213 to move downwards. Under the friction between the first clamping shaft 2122, the second clamping shaft 2132 and the escape rope, the distance between the first clamping shaft 2122 and the second clamping shaft 2132 will gradually decrease, thereby providing a safety barrier for the escape rope located between them. The escape rope clamping achieves gravity self-locking. That is, in the initial state, the greater the force acting on the first fixed back plate 212, the greater the clamping force of the first clamping shaft 2122 and the second clamping shaft 2132 on the escape rope, thus preventing falling. If it is necessary to move downward, the unlocking rod 214 and the transmission plate 215 can be driven to move downward, thereby increasing the distance between the first clamping shaft 2122 and the second clamping shaft 2132, reducing the clamping force on the escape rope, and allowing the entire escape device to gradually descend and achieve escape.

[0072] Understandably, since the first clamping shaft 2122 and the second clamping shaft 2132 lock the escape rope under the action of gravity, when the housing 211 moves upward, the first clamping shaft 2122 is unlocked relative to the first fixed back plate 212 when it moves downward. At this time, the housing 211 can drive the first self-locking component 210 to move upward to achieve climbing. Similarly, the second self-locking component 220 also moves upward to climb using the same principle. The first self-locking component 210 and the second self-locking component 220 move upward in sequence to achieve climbing and escape.

[0073] In some embodiments, the first unlocking component 201 and the second unlocking component 202 have the same structure. The first unlocking component 201 includes a mounting plate 2011, a drive shaft 2013 is rotatably mounted on the mounting plate 2011, a drive gear set 2012 is provided at one end of the drive shaft 2013, a driven gear 2014 is provided at the end of the drive shaft 2013 away from the drive gear set 2012, a rack 2015 is meshed with the driven gear 2014, the end of the rack 2015 is connected to the unlocking rod 214, an extension shaft is provided at the bottom of the rack 2015, a spring 2016 is provided on the circumference of the extension shaft, one end of the spring 2016 abuts against the rack 2015, and the end of the spring 2016 away from the rack 2015 abuts against a protrusion on the mounting plate 2011.

[0074] Please see Figure 1 , Figure 2 , Figure 9 , Figure 12 as well as Figure 13 As shown, since the first unlocking component 201 and the second unlocking component 202 have the same structure, their principles and functions are also the same. Therefore, the first unlocking component 201 is used as an example here. The active gear set 2012 is connected to the sixth bevel gear 4112 through the connecting shaft. The active gear set 2012 then drives the driven gear 2014 to rotate through the drive shaft 2013. Therefore, during the rotation of the driven gear 2014, the rack 2015 connected to the unlocking rod 214 will move downward, thereby realizing the unlocking by driving the first clamping shaft 2122 downward through the unlocking rod 214 and the transmission plate 215. When unlocking is not required, the rack 2015 moves upward under the action of the spring 2016 and the gravity acting on the shell 211 reduces the distance between the first clamping shaft 2122 and the second clamping shaft 2132, and re-clamps and locks the escape rope.

[0075] In this embodiment, the active gear set 2012 is composed of multiple spur gears. Different gear ratios can be adaptively selected according to the distance that the unlocking rod 214 and the transmission plate 215 descend to unlock the first clamping shaft 2122, thereby meeting the unlocking requirements. The module, transmission ratio, etc. of the spur gears are not described in detail here.

[0076] In some embodiments, a handle 500 is provided at the middle position of the first column 110 and the middle position of the second column 120, a first pedal 111 is fixedly provided at the bottom of the first column 110, and a second pedal 121 is fixedly provided at the bottom of the second column 120.

[0077] Please see Figure 1 , Figure 2 as well as Figure 14As shown, in order to provide users with footholds, a first footrest 111 and a second footrest 121 are respectively installed at the bottom of the first pillar 110 and the second pillar 120, so that people can stand on them. Furthermore, the first footrest 111 and the second footrest 121 should also be equipped with straps to fix the feet of the human body. Under the action of the straps, the person can lift their feet to help the first pillar 110 and the second pillar 120 climb upwards to escape.

[0078] In this embodiment, since the first self-locking component 210 is located at the top of the first column 110 and the second self-locking component 220 is located at the bottom of the second column 120, by providing handles 500 in the middle of both the first column 110 and the second column 120, the assembly efficiency can be improved by gripping the handles 500 during the assembly of the escape device.

[0079] See Figure 14 As shown, a safety ring is provided on the first column 110 or the second column 120, and a housing 600 is provided on both the first column 110 and the second column 120. The housing 600 is used to isolate and protect the user from the first column 110 and the second column 120.

[0080] The working process of this invention is as follows: The entire gravity self-locking high-altitude escape device operates based on a gravity self-locking and unlocking control mechanism, involving the coordinated action of core components such as the support 100, self-locking device 200, unlocking drive assembly 300, and transmission rod 400. The escape rope, such as a steel wire rope or nylon rope, passes sequentially from top to bottom through the first self-locking assembly 210 and the second self-locking assembly 220 of the self-locking device 200. In the initial state or under the influence of gravity, the first self-locking assembly 210 and the second self-locking assembly 220 move within the inclined first groove 2121 and second groove 2131 via their internal first clamping shaft 2122 and second clamping shaft 2132, automatically clamping the escape rope to achieve gravity self-locking, preventing accidental slippage and ensuring safety. When the user needs to escape downwards, unlocking is triggered by operating the first drive assembly 310 or the second drive assembly 320 of the unlocking drive assembly 300. Taking the first drive assembly 310 as an example, when the user pulls the drive rod 3102, the sector teeth 3104 at its end mesh with the unlocking drive gear 3103, causing the unlocking drive gear 3103 to rotate, and then transmitting power to the first transmission assembly 311 through the first transmission shaft 3105. The second bevel tooth 3113 in the first transmission assembly 311 receives the power and drives the first bevel tooth 3112 to rotate. The first bevel tooth 3112 is connected to the first rod 410, thereby driving the first rod 410 to rotate. At the same time, the first bevel tooth 3112 transmits power to the transmission device 321 through the third bevel tooth 3114 and the first transmission joint 3115 via the flexible shaft 301. The transmission device 321 transmits power to the third rod 3212 through the third transmission joint 3214, and then to the second rod 420 through the second transmission joint 3213, realizing the synchronous rotation of the first rod 410 and the second rod 420. The first rod 410 and the second rod 420 respectively convert the rotational power direction through the third transmission assembly 411 and the fourth transmission assembly 421 at their ends. Taking the third transmission assembly 411 as an example, the sixth bevel tooth 4112 on the first rod 410 meshes with the seventh bevel tooth 4113, driving the seventh bevel tooth 4113 to rotate, thereby driving the active gear set 2012 of the first unlocking assembly 201. The active gear set 2012 drives the driven gear 2014 to rotate through the drive shaft 2013. The driven gear 2014 meshes with the rack 2015, causing the rack 2015 to move downward. The end of the rack 2015 is connected to the unlocking rod 214. The unlocking rod 214 drives the first clamping shaft 2122 to move downward in the first inclined groove 2121 through the transmission plate 215. Due to the inclined design of the inclined groove, the first clamping shaft 2122 moves away from the second clamping shaft 2132, increasing the gap and releasing the clamp on the escape rope. Similarly, the second self-locking component 220 unlocks through the same mechanism, thereby achieving synchronous unlocking of the first self-locking component 210 and the second self-locking component 220, allowing the escape device to descend controllably under gravity. After unlocking, the spring 2016 pushes the rack 2015 upward to reset, causing the self-locking components to re-clamp the escape rope.Users can operate the device by stepping on the first pedal 111 and the second pedal 121 and gripping the handle 500. When climbing upwards, users alternately lift the first column 110 and the second column 120. The self-locking component automatically unlocks as the user moves upwards, allowing upward movement. Throughout the process, the flexible shaft 301 and the transmission rod 400 ensure reliable transmission of unlocking power, avoiding unlocking failures caused by traditional rope extension, and improving the safety and applicability of escape.
