Description

Technical Field

[0001] This utility model relates to the field of escape equipment technology, and in particular to an escape device. Background Technology

[0002] In the field of emergency escape in high-rise buildings, slow-descent escape devices generally adopt a symmetrical shell structure to optimize stress distribution. In a typical solution disclosed in Chinese patent CN201410305603.2, two locking devices are respectively located at the upper and lower ends of the shell assembly, while the unlocking mechanism is centrally located in the top area of ​​the shell. Although this structure achieves functional integration, it has significant assembly defects:

[0003] When assembling the locking device onto a vertically suspended escape rope, the operator must maintain the locking device in the unlocked state throughout the process. This requires simultaneously operating the two unlocking mechanisms at the top of the housing and applying opposing compressive forces to the left and right sides of the housing to force the bottom locking device to initially engage with the rope. However, because the longitudinal dimension of the housing along the rope's circumference is much larger than its lateral force-bearing width (i.e., exhibiting a high length-to-diameter ratio), the lateral pressure applied at the top induces elastic bending deformation of the housing. This deformation causes mechanical energy to be converted into structural strain energy and absorbed, preventing the force from being effectively transmitted axially to the bottom locking device. In emergency escape scenarios, this operation not only significantly reduces installation reliability but also, due to repeated pressure application leading to operational delays or assembly failures, could potentially delay escape opportunities and cause fatal accidents. Therefore, we provide an escape device to address these issues. Utility Model Content

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0044] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0045] like Figure 1 — Figure 15 The example shown.

[0046] An escape device includes a pillar 100, a gravity self-locking device 200, a first handle assembly 300, a transmission device 400, and a second handle assembly 500.

[0047] In some specific embodiments, the column 100 includes a first column 110 and a second column 120 respectively spaced apart; the gravity self-locking device 200 includes a first locking device 210 and a second locking device 220; the first locking device 210 is fixedly installed on the first column 110 and slidably connected to the first column 110; the second locking device 220 is fixedly installed on the second column 120 and slidably connected to the second column 120; the first handle assembly 300 includes a first unlocking handle 310 fixedly installed on the top of the first column 110 and a second unlocking handle 320 fixedly installed on the top of the second column 120; and the transmission device 400. The device includes a first transmission assembly 410 disposed at the unlocking end of the first locking device 210 and a second transmission assembly 420 disposed at the unlocking end of the second locking device 220. The first unlocking handle 310 is drivenly connected to the first transmission assembly 410 and / or the second transmission assembly 420. The second unlocking handle 320 is drivenly connected to the first transmission assembly 410 and / or the second transmission assembly 420. The second handle assembly 500 includes a third unlocking handle 510 disposed in the middle of the first column 110 and a fourth unlocking handle 520 disposed in the middle of the second column 120. The third unlocking handle 510 is drivenly connected to the first transmission assembly 410 and the fourth unlocking handle 520 is drivenly connected to the second transmission assembly 420.

[0048] In this embodiment, the third unlocking handle 510 and the fourth unlocking handle 520 are located at the middle positions of the first column 110 and the second column 120, respectively. Since the third unlocking handle 510 is connected to the first transmission assembly 410, it can unlock the first locking device 210; and since the fourth unlocking handle 520 is connected to the second transmission assembly 420, it can unlock the second locking device 220. Therefore, when it is necessary to install the first locking device 210 and the second locking device 220 with the rope A, the third unlocking handle 510 is held by the user's two hands. The locking handle 510 and the fourth unlocking handle 520 apply unlocking force, and the unlocking force from the two hands is transmitted to the first transmission component 410 and the second transmission component 420 respectively to unlock the first locking device 210 and the second locking device 220. Then, when installing to the rope A, the first column 110 and the second column 120 can be applied by the third unlocking handle 510 and the fourth unlocking handle 520 respectively, so that the first column 110 and the second column 120 move closer to each other, thereby enabling the first locking device 210 and the second locking device 220 to be installed in conjunction with the rope A.

[0049] Understandably, since the third unlocking handle 510 and the fourth unlocking handle 520 are located at the middle of the first column 110 and the second column 120 respectively, it is easier to transmit force to both ends of the first column 110 and the second column 120. That is, the distance between the position where the force is applied and the first locking device 210 and the second locking device 220 is equal, reducing the length-to-diameter ratio and thus preventing deformation of the first column 110 and the second column 120. This allows the force to be smoothly transmitted to the first locking device 210 and the second locking device 220 to achieve the installation of the rope A.

[0050] In this embodiment, unlocking refers to the first locking device 210 and the second locking device 220 releasing the clamping force on the rope, thereby allowing the entire escape device to move downward or upward along the rope direction. Similarly, locking refers to clamping the rope through the first locking device 210 and the second locking device 220 to prevent the entire escape device from falling uncontrollably.

[0051] Please see Figure 1As shown, in this embodiment, the first unlocking handle 310 can simultaneously drive the first transmission component 410 and the second transmission component 420 and simultaneously unlock the first locking device 210 and the second locking device 220. Similarly, the second unlocking handle 320 can also simultaneously drive the first transmission component 410 and the second transmission component 420 and simultaneously unlock the first locking device 210 and the second locking device 220. That is, when unlocking, the first locking device 210 and the second locking device 220 can be unlocked simultaneously through either the first unlocking handle 310 or the second unlocking handle 320. Therefore, the first locking device 210 and the second locking device 220 can be unlocked simultaneously with one hand, thereby enabling the device to be used by a person with a disability who has only one hand (only one hand that can move normally), improving the practicality of the escape device. It should be noted that the entire escape device needs to be assembled by a person with normal mobility of both hands, and it can be used by a person with a disability who has only one hand.

[0052] In another embodiment, the first unlocking handle 310 can be connected to the first transmission component 410 to unlock the first locking device 210, and the second unlocking handle 320 can be connected to the second transmission component 420 to unlock the second locking device 220. This method is suitable for ordinary people with normal hands, that is, the first locking device 210 and the second locking device 220 can be unlocked by the linkage of both hands.

[0053] In another embodiment, the first unlocking handle 310 is connected to the second transmission component 420 so as to unlock the second locking device 220. The second unlocking handle 320 is connected to the first transmission component 410 so as to unlock the first locking device 210. This method is suitable for ordinary people who can move their hands normally, that is, the first locking device 210 and the second locking device 220 can be unlocked by the linkage of both hands.

[0054] In this embodiment, in order to enable the first locking device 210 and the second locking device 220 to be unlocked simultaneously, the first unlocking handle 310 is connected to the first transmission component 410 and the second transmission component 420 to unlock the first locking device 210 and the second locking device 220 simultaneously, and the second unlocking handle 320 is also connected to the first transmission component 410 and the second transmission component 420 to unlock the first locking device 210 and the second locking device 220 simultaneously. The following description is based on this transmission unlocking method.

[0055] In this embodiment, the first locking device 210 and the second locking device 220 have the same structure, and the following explanation will focus on the first locking device 210; the first unlocking handle 310, the second unlocking handle 320, the third unlocking handle 510 and the fourth unlocking handle 520 have the same structure, and the following explanation will focus on the first unlocking handle 310; the first transmission assembly 410 and the second transmission assembly 420 have the same structure, and the following explanation will focus on the mounting plate 411.

[0056] In some specific embodiments, the driving end of the first transmission component 410 is connected to a first unlocking rope A1 and a third unlocking rope B1, respectively. The end of the first unlocking rope A1 facing away from the first transmission component 410 is connected to a first transmission rope A11 and a second transmission rope A12, respectively. The first transmission rope A11 is connected to the first unlocking handle 310, the second transmission rope A12 is connected to the second unlocking handle 320, and the third unlocking rope B1 is connected to the third unlocking handle 510. The driving end of the second transmission component 420 is connected to a second unlocking rope A2 and a fourth unlocking rope B2, respectively. The end of the second unlocking rope A2 facing away from the second transmission component 420 is connected to a third transmission rope A21 and a fourth transmission rope A22, respectively. The third transmission rope A21 is connected to the second unlocking handle 320, the fourth transmission rope A22 is connected to the first unlocking handle 310, and the fourth unlocking rope B2 is connected to the fourth unlocking handle 520.

[0057] See Figure 2 As shown, the first locking device 210 is located above, and the second locking device 220 is located below. The first unlocking rope A1 and the second unlocking rope A2 are respectively connected to the first transmission assembly 410 and the second transmission assembly 420. That is, when force is transmitted to the first transmission assembly 410 through the first unlocking rope A1, the first locking device 210 can be driven to unlock, releasing the clamping force of the first locking device 210 on the rope A. Similarly, when force is transmitted to the second transmission assembly 420 through the second unlocking rope A2, the second locking device 220 can be driven to unlock, releasing the clamping force of the second locking device 220 on the rope A.

[0058] Please continue reading. Figure 2 As shown, since the first unlocking handle 310 is connected to both the second transmission rope A12 and the fourth transmission rope A22, and the second transmission rope A12 is connected to the first unlocking rope A1, and the fourth transmission rope A22 is connected to the second unlocking rope A2, the first unlocking handle 310 can transmit the unlocking force to the first unlocking rope A1 and the second unlocking rope A2 through the second transmission rope A12 and the fourth transmission rope A22, thereby transmitting the unlocking force to the first transmission assembly 410 and the second transmission assembly 420, thus unlocking the first locking device 210 and the second locking device 220.

[0059] Please continue reading. Figure 2 As shown, the second unlocking handle 320 is connected to both the first transmission rope A11 and the third transmission rope A21. The first transmission rope A11 is connected to the first unlocking rope A1, and the third transmission rope A21 is connected to the second unlocking rope A2. Therefore, the second unlocking handle 320 can transmit the unlocking force to the first unlocking rope A1 and the second unlocking rope A2 through the first transmission rope A11 and the third transmission rope A21, and then transmit the unlocking force to the first transmission assembly 410 and the second transmission assembly 420, thereby enabling the unlocking of the first locking device 210 and the second locking device 220.

[0060] As described above, when unlocking for escape, the unlocking force can be applied to the first unlocking handle 310 or the second unlocking handle 320 by gripping it. Both can simultaneously unlock the first locking device 210 and the second locking device 220, releasing the clamping force on the rope A. This allows the entire escape device to move downwards under the guidance of the rope A to achieve escape.

[0061] Please continue reading. Figure 2 As shown, the third unlocking handle 510 is located below the first transmission assembly 410, and the fourth unlocking handle 520 is located above the second transmission assembly 420. When the escape device needs to be installed in conjunction with rope A, both hands simultaneously hold the third unlocking handle 510 and the fourth unlocking handle 520 to transmit the unlocking force to the first transmission assembly 410 and the second transmission assembly 420 respectively, thereby driving the first locking device 210 and the second locking device 220 to unlock. It should be noted that since the third unlocking handle 510 is located below the first transmission assembly 410, in order to move the unlocking end of the first transmission assembly 410 upward to achieve unlocking, a steering wheel B11 needs to be set at the position of the first transmission assembly 410 to change the transmission direction of the force of the third unlocking rope B1.

[0062] Please see Figure 3 As shown, the first unlocking handle 310 includes a gripping member 311 fixedly connected to the first column 110. A first guide wheel 312 and a second guide wheel 313 are rotatably mounted on the gripping member 311. The first guide wheel 312 and the second guide wheel 313 guide the second transmission rope A12 and the fourth transmission rope A22. A driving member 314 is also rotatably mounted on the gripping member 311. The driving member 314 is connected to the second transmission rope A12 and the fourth transmission rope A22. When a person drives the driving member 314 to rotate, the unlocking force can be transmitted to the first transmission assembly 410 and the second transmission assembly 420 through the second transmission rope A12 and the fourth transmission rope A22, thereby unlocking the first locking device 210 and the second locking device 220. The second unlocking handle 320 has the same structure and the same principle as the first unlocking handle 310. Therefore, the second unlocking handle 320 will not be described in detail here.

[0063] In this embodiment, the first unlocking rope A1, the first transmission rope A11, the second transmission rope A12, the second unlocking rope A2, the third transmission rope A21, the fourth transmission rope A22, the third unlocking rope B1, and the fourth unlocking rope B2 can all be bicycle brake cables. The cable consisting of the first unlocking rope A1, the first transmission rope A11, and the second transmission rope A12 can be a one-to-two brake cable. Similarly, the cable consisting of the second unlocking rope A2, the third transmission rope A21, and the fourth transmission rope A22 can also be a one-to-two brake cable.

[0064] In some specific embodiments, the first locking device 210 includes a first housing 211 and a second housing 212. The first housing 211 and the second housing 212 are rotatably connected and cooperate to form a mounting cavity. Two first upright plates 213 are fixedly installed on the first housing 211, and at least one first clamping wheel 214 is provided between the two first upright plates 213. Two second upright plates 215 are fixedly installed in the second housing 212. Each second upright plate 215 is provided with a first guide groove 2151 and a second guide groove 2152 spaced apart from top to bottom. In a side view, the openings of the first guide groove 2151 and the second guide groove 2152 are gradually... The diameter gradually increases, and a second clamping wheel 216 is provided between the two first guide grooves 2151, with the ends of the second clamping wheel 216 located in the first guide grooves 2151 respectively. The safety rope is located between the second clamping wheel 216 and the first clamping wheel 214. A transmission wheel 217 is provided between the two second guide grooves 2152, with the transmission wheel 217 located in the second guide groove 2152. A transmission plate 218 is installed between the two ends of the second clamping wheel 216 and the transmission wheel 217. The transmission wheel 217 is the unlocking end of the first locking device 210. The transmission wheel 217 is connected to the first transmission assembly 410, which is used to drive the transmission wheel 217 to move downward.

[0065] See Figure 9 and Figure 10As shown, the first clamping wheel 214 has two that rotate on the frame formed by the two first upright plates 213. Correspondingly, there are also two second clamping wheels 216, which are also rotatably mounted on the frame formed by the two transmission plates 218. The transmission wheel 217 is located below the second clamping wheel 216. The top second clamping wheel 216 is located in the first guide groove 2151 of the second upright plate 215, and the two ends of the upper first guide groove 2151 abut against the inner wall of the first guide groove 2151. The bottom second clamping wheel 216 is located in the second guide groove 2152, and the two ends of the bottom second clamping wheel 216 abut against the inner wall of the second guide groove 2152. The two ends of the transmission wheel 217 also abut against the inner wall of the second guide groove 2152. In this embodiment, the first guide groove 2151 and the second guide groove 2152 gradually increase in size from top to bottom. Specifically, the inner walls of the first guide groove 2151 and the second guide groove 2152 are inclined.

[0066] Please continue reading. Figure 9 and Figure 10 As shown, when the transmission wheel 217 is given a force to drive the transmission plate 218 to move downward, the second clamping wheel 216 gradually moves away from the first clamping wheel 214 under the guidance of the inclined inner walls of the first guide groove 2151 and the second guide groove 2152, thereby increasing the distance between the second clamping wheel 216 and the first clamping wheel 214, thereby reducing the clamping force of the second clamping wheel 216 and the first clamping wheel 214 on the rope C located between them, and realizing unlocking.

[0067] Understandably, when no downward unlocking force is applied to the drive wheel 217, the friction between the entire escape device and the second clamping wheel 216 and the rope C causes the second clamping wheel 216 to move upward under the guidance of the inclined inner walls of the first guide groove 2151 and the second guide groove 2152. This reduces the distance between the first clamping wheel 214 and the second clamping wheel 216, thereby increasing the clamping force of the first clamping wheel 214 and the second clamping wheel 216 on the rope C located between them. At this time, the relative position of the entire escape device and the rope C remains unchanged, thus locking the rope C.

[0068] In some specific embodiments, the first locking device 210 further includes a detachable structure 219 for detachable connection between the first housing 211 and the second housing 212. The detachable structure 219 includes a first rod 2191 disposed within the first housing 211, and a second rod 2192 slidably disposed vertically within the second housing 212. At least one locking block 21910 is disposed on the side wall of the first rod 2191 facing the second rod 2192, and the second rod 2192 faces the first rod 2191. The side wall of 2191 is provided with a slot 21920 that is adapted to the card block 21910. The end of the second rod 2192 is provided with a slide rod 21921 that penetrates the side wall of the second housing 212 and is slidably connected to it. A first elastic element 21922 is sleeved on the slide rod 21921. The first elastic element 21922 is located between the side wall of the second housing 212 and the second rod 2192. A first knob 230 is also provided on the first column 110. The first knob 230 is connected to the slide rod 21921 in a transmission manner.

[0069] Please see Figure 4 , Figure 11 and Figure 12 As shown, the first housing 211 and the second housing 212 are rotatably connected by a rotating shaft. The other side of the rotating shaft away from the first housing 211 and the second housing 212 are detachably connected by a detachable structure 219. Specifically, the first knob 230 and the slide rod 21921 are connected by a transmission line. When the first locking device 210 needs to be installed with the rope C, firstly, the first knob 230 needs to be rotated to drive the slide rod 21921 to overcome the elastic force of the first elastic element 21922 and slide on the second housing 212, so that the locking block 21910 is disengaged from the locking groove 21920. At this time, the first housing 211 and the second housing 212 can rotate along the rotating shaft, and the other side of the first housing 211 and the second housing 212 away from the rotating shaft are separated, and the two are separated.

[0070] In this embodiment, a sloping guide surface is provided at the position of the locking block 21910, and a matching sloping guide surface is also provided at the corresponding position of the locking slot 21920. When the first housing 211 and the second housing 212 are combined to achieve installation with the rope C, the first housing 211 and the second housing 212 only need to rotate along the axis of rotation to approach each other, and the locking block 21910 contacts the sloping guide surface at the position of the locking slot 21920. As the first housing 211 and the second housing 212 continue to approach and rotate, the locking block 21910 overcomes the elastic force of the first elastic member 21922 and moves the second rod 2192 under the abutment of the two sloping guide surfaces. Finally, the locking block 21910 enters the locking slot 21920. After the locking block 21910 enters the locking slot 21920 and achieves locking, the second rod 2192, under the action of the elastic force of the first elastic member 21922, makes the locking block 21910 engage with the locking slot 21920, preventing the two from separating.

[0071] In this embodiment, the way in which the second knob 240 opens and closes the second column 120 is the same as the way in which the first knob 230 opens and closes the first column 110, and will not be described in detail here. Those skilled in the art can deduce the way in which the second knob 240 opens and closes the second column 120 based on the way in which the first knob 230 opens and closes the first column 110.

[0072] In this embodiment, the first elastic element 21922 is a spring.

[0073] In some specific embodiments, the first transmission assembly 410 includes a mounting plate 411 slidably mounted on the mounting groove of the first column 110. A drive wheel 412 is rotatably mounted on the mounting plate 411. A driven wheel assembly 413 is also rotatably mounted on the mounting plate 411. A first bevel tooth 414 is provided at the power end of the driven wheel assembly 413. A first extension plate 4111 is provided on one side of the mounting plate 411. A second bevel tooth 415 is rotatably mounted on the first extension plate 4111. The first bevel tooth 414 and the second bevel tooth 415 are connected in a transmission manner. The tooth 415 has a threaded hole, in which a lead screw 416 is installed. The end of the lead screw 416 away from the second bevel tooth 415 is connected to the unlocking end of the first locking device 210. The mounting plate 411 extends downward to provide a second extension plate 4112. A second elastic member 417 is hung between the second extension plate 4112 and the drive wheel 412. The mounting groove of the first column 110 is also provided with a first limiting member 201 located below the second extension plate 4112. The first limiting member 201 and the second extension plate 4112 define a preset distance.

[0074] Please see Figure 5 , Figure 6 as well as Figure 7As shown, the first transmission assembly 410 is used as an example. Specifically, the first unlocking rope A1 drives the driving wheel 412 to rotate at a certain angle. Under the speed change action of the driven wheel assembly 413, the first bevel gear 414 rotates, and then drives the second bevel gear 415 to rotate. Since the second bevel gear 415 has a threaded hole that is threaded to engage with the lead screw 416, the rotation of the second bevel gear 415 drives the lead screw 416 to move away from the transmission wheel 217. This drives the transmission wheel 217 and the transmission plate 218 to move downward, and also drives the second clamping wheel 216 to move downward, thereby increasing the distance between the second clamping wheel 216 and the first clamping wheel 214, reducing the clamping force on the rope C, and realizing unlocking.

[0075] In this embodiment, the driven wheel assembly 413 is composed of multiple gears, which work together to achieve speed change, specifically to increase speed. This means that the number of rotations of the driving wheel 412 is increased, so that the first bevel gear 414 and the second bevel gear 415 can rotate more times to drive the lead screw 416 to move downward or upward.

[0076] In this embodiment, in order to enable the lead screw 416 to drive the transmission wheel 217 and the transmission plate 218 back to their initial positions, thereby reducing the distance between the second clamping wheel 216 and the first clamping wheel 214 to clamp and fix the rope C, the drive wheel 412 is also connected to a second elastic element 417. The other end of the second elastic element 417 is connected to the second extension plate 4112. In the initial state, the second elastic element 417 does not provide tension to the drive wheel 412. Only when the drive wheel 412 is pulled and rotated by the first unlocking rope A1 will the second elastic element 417 provide tension. The rope C will only be stretched when the second elastic element 417 is stretched. Under the action of the second elastic element 417, the driving wheel 412 rotates in the opposite direction. Under the transmission action of the driven wheel group 413, the first bevel gear 414 and the second bevel gear 415, the lead screw 416 moves upward, thereby driving the transmission wheel 217, the transmission plate 218 and the second clamping wheel 216 to move upward. This reduces the distance between the first clamping wheel 214 and the second clamping wheel 216, clamping and fixing the rope C, thus completing the locking state of the rope C. At this time, the position of the entire escape device relative to the position of the rope C remains unchanged.

[0077] In this embodiment, the combined transmission between the drive wheel 412, driven wheel set 413, first bevel gear 414, and second bevel gear 415 allows for precise control of the length by which the lead screw 416 drives the transmission wheel 217 and transmission plate 218 to descend. This precisely controls the distance between the first clamping wheel 214 and the second clamping wheel 216, thereby controlling the clamping force on the rope C and ultimately controlling the descent speed of the entire escape device and the person standing on it.

[0078] In this embodiment, the second elastic element 417 is a spring.

[0079] In some specific embodiments, a fixing groove 41110 is provided on the first extension plate 4111, and a bearing 4151 connected to the second bevel tooth 415 is provided in the fixing groove 41110. At least one recess 41111 is also provided on the upper surface of the first extension plate 4111. A pressure plate 418 is provided on the first extension plate 4111. A pressure groove 4181 is provided on the side of the pressure plate 418 facing the first extension plate 4111. The side wall of the pressure groove 4181 abuts against the outer ring of the bearing 4151. A protrusion 4182 adapted to the recess 41111 is also provided on the side of the pressure plate 418 facing the first extension plate 4111.

[0080] Please see Figure 6 , Figure 7 as well as Figure 8 As shown, in order to allow the second bevel gear 415 to be rotatably mounted on the first extension plate 4111, a fixing groove 41110 is formed in the first extension plate 4111. A bearing 4151 is then installed in the fixing groove 41110, and the inner ring of the bearing 4151 is connected to the shoulder of the second bevel gear 415. Furthermore, to prevent the bearing 4151 from dislodging from the fixing groove 41110, a pressure plate 418 is also fixedly installed on the first extension plate 4111. When installing the pressure plate 418, first align the pressure groove 4181 of the pressure plate 418 with the outer ring of the bearing 4151, and press the top wall of the pressure groove 4181 against the outer ring of the bearing 4151 to prevent the bearing 4151 from dislodging from the fixing groove 41110. Also, make the recessed part 41111 cooperate with the protrusion 4182 of the pressure plate 418 to prevent the pressure plate 418 from shifting position. Finally, bolts can be used to fix the pressure plate 418 to the first extension plate 4111.

[0081] In this embodiment, both the recessed portion 41111 and the protruding portion 4182 are linear. Of course, in other embodiments, the recessed portion 41111 and the protruding portion 4182 can also be square, cylindrical, or other shapes. The specific shape can be selected according to actual needs, and there is no limitation here.

[0082] In some specific embodiments, a limiting component 700 is provided at the top of the first column 110 or the top of the second column 120. The limiting component 700 includes a mounting frame 710, which has a mounting chamber 711. A rotating frame 720 is rotatably mounted in the mounting chamber 711. A roller 730 is rotatably mounted at the end of the rotating frame 720, and an inclined limiting plate 740 is fixedly mounted thereon. An accommodating space is formed between the roller 730 and the limiting plate 740. A locking hole 721 is provided on the rotating frame 720. A plug-in structure 750 is fixedly mounted on the mounting frame 710, and the limiting part of the plug-in structure 750 is located in the locking hole 721. The plug-in structure 750 includes a tube 751 fixed on the mounting bracket 710. The tube 751 has a guide hole 7511. A locking pin 752 is slidably disposed in the guide hole 7511. The end of the locking pin 752 facing the rotating bracket 720 is a limiting part. The limiting part passes through the mounting bracket 710 into the locking hole 721. A third elastic member 753 is sleeved on the circumferential surface of the locking pin 752. One end of the third elastic member 753 abuts against the stepped surface of the locking pin 752. A pull rod 754 is provided at the end of the locking pin 752 away from the mounting bracket 710.

[0083] See Figure 1 , Figure 13 and Figure 14 As shown, in order to prevent the rope C from deviating when entering the first locking device 210 and the second locking device 220, a limiting component 700 is provided at the top of the first column 110 or the second column 120 to limit the position of the rope, so that it enters the first locking device 210 in a vertical state, and prevents the descent and escape from being affected by the deviation of the rope C.

[0084] For details, please continue reading. Figure 1 , Figure 13 as well as Figure 14 As shown, in this embodiment, in the initial state, the mounting frame 710 is fixedly installed at the top of the first column 110. The rotating frame 720 is rotatably installed in the mounting chamber 711 of the mounting frame 710. The ends of the rotating frame 720 away from the mounting frame 710 are respectively rotatably installed with rollers 730 and inclined fixed limiting plates 740. A accommodating space is formed between the rollers 730 and the limiting plates 740 to limit the rope C and allow it to pass through. This accommodating space is located directly above the rope C entrance of the first locking device 210, thereby ensuring that the rope C can enter the first locking device 210 vertically.

[0085] Furthermore, in order to ensure that the accommodating space is located directly above the rope C inlet of the first locking device 210, a plug-in structure 750 is also fixedly installed on the rotating frame 720. The plug-in structure 750 extends into the locking hole 721 of the rotating frame 720 to prevent the rotating frame 720 from rotating and causing the accommodating space to shift. In this embodiment, the tube 751 is fixedly installed on the bottom surface of the mounting frame 710, and the guide hole 7511 of the tube 751 communicates with the mounting chamber 711. The locking hole 721 is located directly above the locking pin 752. Under the elastic force of the third elastic member 753, the limiting part at the top of the locking pin 752 is driven to extend into the locking hole 721 to limit the position of the rotating frame 720 and prevent the rotating frame 720 from rotating and causing the accommodating space to shift.

[0086] During initial installation, the limiting part of the locking pin 752 can be disengaged from the locking hole 721 by pulling the lever 754 to overcome the elastic force of the third elastic element 753, thereby releasing the limiting of the rotating frame 720. At this time, the rotating frame 720 can be rotated to move the position of the accommodating space to meet the installation requirements of setting the rope C in the accommodating space.

[0087] In this embodiment, the third elastic element 753 is a spring.

[0088] In some specific embodiments, a slider 4113 is fixedly provided on the side wall of the mounting plate 411 facing the first column 110. The slider 4113 is disposed in the mounting groove of the first column 110. Mounting grooves 41130 are provided on both sides of the slider 4113, and ball bearings 4114 are disposed in the mounting grooves 41130.

[0089] The escape device also includes a pedal assembly 600, which includes a first pedal 610 and a second pedal 620. The first pedal 610 is fixedly installed at the bottom of the first column 110, and the second pedal 620 is fixedly installed at the bottom of the second column 120. A strap 800 is fixedly installed on the first column 110 or the second column 120.

[0090] See Figure 1 , Figure 3As shown, both the first pedal 610 and the second pedal 620 are equipped with limiting straps to fix the human feet, thereby preventing the human feet from leaving the first pedal 610 and the second pedal 620. In this embodiment, in order to enable the user to climb up the rope C using the escape device, a first limiting member 201 is fixedly installed on the first column 110, and the first limiting member 201 is located below the second extension plate 4112. Specifically, when the left foot steps on the first pedal 610, the left foot is restricted on the first pedal 610 by the limiting strap, and the right foot steps on the second pedal 620, the right foot is restricted on the second pedal 620 by the limiting strap. It can be understood that by raising the left and right feet, the first column 110 and the second column 120 can be moved upward.

[0091] For example, when a person climbs upward through the escape device, taking the left foot driving the first column 110 upward as an example, as the left foot lifts upward, the first column 110 and the first locking device 210 will move upward. Since the second clamping wheel 216 is no longer subjected to an upward force from the rope C, the distance between the first clamping wheel 214 and the second clamping wheel 216 increases, releasing the clamping force on the rope C. Under the action of gravity, the second clamping wheel 216, the transmission wheel 217, and the transmission plate 218 will move downward along with the first transmission assembly 410 for a certain distance until the second extension plate 4112 abuts against the first limiting member 201. The first limiting member 201 supports the second extension plate 4112 to prevent it from moving downward. Next, after the left foot is lifted to a certain height, it no longer exerts an upward force on the first column 110 through the limiting strap and the first pedal 610. The force is applied to the second clamping wheel 216, causing the rope C to release from the second clamping wheel 216 and exert an upward force on it. This causes the second clamping wheel 216 to move upward under the guidance of the first guide groove 2151 and the second guide groove 2152. The distance between the first clamping wheel 214 and the second clamping wheel 216 gradually decreases, thus clamping and fixing the rope C. The upward movement of the second clamping wheel 216 and the transmission plate 218 will inevitably drive the transmission wheel 217 to move upward. The transmission wheel 217 will then drive the first transmission assembly 410 to move upward a certain distance until the mounting plate 411 of the first transmission assembly 410 abuts against the first housing 211 and the second housing 212 to achieve position limitation. At this time, the distance between the second clamping wheel 216 and the first clamping wheel 214 decreases, thus clamping and fixing the rope C, so that the positions of the first locking device 210 and the first column 110 relative to the rope C remain unchanged.

[0092] It should be noted that after the left foot is raised, the right foot needs to be raised as well. The right foot drives the second column 120 to move upward through the limiting band, the second pedal 620, etc. In this embodiment, a second limiting member 202 is installed on the second column 120. The second limiting member 202 is located below the second transmission component 420. The second limiting member 202 prevents the second transmission component 420 from falling downward. It can be understood that when the right foot is raised, the working principle and process of the second locking device 220 and the first locking device 210 are the same, as are the working principle and process of the second transmission component 420 and the first transmission component 410. Therefore, the working process and principle of the second locking device 220 and the second transmission component 420 will not be described in detail here. For details, please refer to the working process and principle of the first locking device 210 and the first transmission component 410 described above.

[0093] In another embodiment, when a person climbs up the rope C using the escape device, if the climbing is affected by the inability of the first locking device 210 and the second locking device 220 to be unlocked in time, the first locking device 210 and the second locking device 220 can be unlocked by the third unlocking handle 510 or the fourth unlocking handle 520 respectively, thereby reducing the climbing speed caused by the inability to unlock in time. The process of the third unlocking handle 510 unlocking the first locking device 210 and the fourth unlocking handle 520 unlocking the second locking device 220 can be referred to the above description, and will not be elaborated here.

[0094] See Figure 15 As shown, in order to prevent the human body from falling off the escape device, a strap 800 is installed on the first column 110 or the second column 120. The strap 800 connects the waist of the human body to the first column 110 or the second column 120, thereby limiting the waist of the human body and preventing the human body from falling off the escape device. In this embodiment, the strap 800 is installed on the first column 110.

[0095] Please continue reading. Figure 15 As shown, in order to improve aesthetics and prevent clothing from entering the first transmission component 410, the second transmission component 420, or other components and causing the escape device to malfunction, a shell 900 is provided for both the first column 110 and the second column 120. The first column 110 and the second column 120 are fitted into the shell 900 to prevent foreign objects from entering the interior and affecting the operation of the escape device.

[0096] The working process of this utility model is as follows: The operator first holds the third unlocking handle (510) and the fourth unlocking handle (520) with both hands at the same time. The third unlocking rope (B1) and the fourth unlocking rope (B2) drive the first transmission component (410) and the second transmission component (420) respectively, so that the lead screw (416) moves down and drives the transmission wheel (217) to move down along the second guide groove (2152). The transmission plate (218) pulls the second clamping wheel (216) to slide outward in the first guide groove (2151), thereby widening the distance between the second clamping wheel (216) and the first clamping wheel (214) to unlock. Then, the first knob (230) is rotated to pull the slide rod (2154). 921) Compress the first elastic element (21922) to disengage the slot (21920) of the second rod (2192) from the block (21910) of the first rod (2191), open the first housing (211) and the second housing (212), place the rope (C) between the first clamping wheel (214) and the second clamping wheel (216) and close the housing. The block (21910) is guided by the inclined guide surface to engage with the slot (21920) to complete the locking, thereby realizing the installation of the first locking device (210) and the rope C. Similarly, operate the second knob (240) to assemble the second locking device (220) so that the second locking device (220) and the rope C are installed.

[0097] When a person descends through the escape device, holding the first unlocking handle (310) or the second unlocking handle (320) drives the second transmission rope (A12) / fourth transmission rope (A22) or the first transmission rope (A11) / third transmission rope (A21) via the drive component (314). The first unlocking rope (A1) / second unlocking rope (A2) synchronously drives the two transmission components (410, 420): the rotation of the drive wheel 412 speeds up the driven wheel group 413, causing the first bevel gear 414 and the second bevel gear 415 to rotate, causing the lead screw 416 to move down and push the transmission wheel 217 to unlock the clamping wheel. After releasing the handle, the second elastic element 417 pulls the drive wheel to reverse, causing the lead screw to move up and reset the clamping. The descent speed is precisely controlled by the pressure of the handle. The third unlocking handle 510 and the fourth unlocking handle 520 operated by the middle of both hands can independently unlock the corresponding locking device.

[0098] When climbing upwards, the left foot steps on the first pedal 610, lifting it and causing the first column 110 to move upwards. Gravity causes the second clamping wheel 216 of the first locking device 210 to move downwards until the second extension plate 4112 abuts against the first limiting member 201 to unlock. After the left foot stops lifting, the rope C pushes the second clamping wheel 216 upwards to reset and lock. The right foot steps on the second pedal 620, similarly operating the second column 120 and limiting it through the second limiting member 202. If obstructed, the third unlocking handle 510 or the fourth unlocking handle 520 can be used to forcibly unlock. Throughout the climb, the waist is secured by a strap 800 to prevent falls, the limiting component 700 ensures the rope enters the locking device vertically, and the outer shell 900 encloses the column to prevent foreign object intrusion. This application solves the problem of column 100 deformation during installation by using the middle handle (510 / 520), and the top handle (310 / 320) enables one-handed simultaneous double unlocking. The climbing mode uses the limit component (201 / 202) and the elastic component 417 to achieve automatic locking / unlocking of the clamping wheel.

[0099] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
