[0039] This application provides an emergency escape system and a brake locking system for the emergency escape device. Using a parallel shaft drive coupled with centrifugal intermittent impact speed control technology, the device utilizes purely mechanical transmission to enable the device to slide down a handrail track with a slope of 28° to 35°, unaffected by dust, water, oil, and other factors, at a constant speed of 0.8m / s to 1.2m / s (no electric drive required, suitable for various emergency situations).

[0040] This device can be used in emergency situations such as fire. The user can slide down at a constant speed from the modified and installed handrail track. During the sliding, the device can be stopped with the brakes at any time and anywhere. It can be completed in about 3 minutes to slide from the 30th floor to the 1st floor. For example, it only takes 180 seconds to slide from the 32nd floor to the 1st floor, thus ensuring both the time requirement for emergency escape and the safety of the escaping object.

[0041] See also Figure 1 , Figure 1 It is a structural diagram of the emergency escape system provided by this application.

[0042] An emergency escape system 100 provided in one embodiment of the present application may include an emergency escape device 2 and a handrail track 1. The emergency escape device 2 includes a brake locking system 20, which is any one of the following brake locking systems 20; the handrail track 1 is matched and connected to the emergency escape device 2.

[0043] See also Figures 2 to 5 , Figure 2 1 is a schematic structural diagram of a brake locking system provided by the present application from one perspective, wherein the brake locking system is in an initial state A; Figure 3 2 is a schematic structural diagram of the brake locking system provided by the present application from another perspective, wherein the brake locking system is in an initial state A; Figure 4 yes Figure 1 A cross-sectional structural diagram along line AA (handrail track omitted), where the brake locking system is in state B and the locking rod is in the upward position; Figure 5 yes Figure 1 Another cross-sectional structural diagram along line AA, in which the brake locking system is in state C, and the locking rod and the second brake assembly are both in the upward state.

[0044] The brake locking system 20 provided in one embodiment of the present application includes: a first brake assembly 21 and a second brake assembly 22. The first brake assembly 21 includes a load-bearing portion 211, a hanging rod 212, a locking rod 213, and a locking head 214. The load-bearing portion 211 can be a hook, a frame, etc., for carrying an object that needs to be used for emergency escape. The load-bearing portion 211 and the hanging rod 212 are movably connected, and can be rotatably connected via a second rotating shaft 23. The hanging rod 212 and the locking rod 213 are movably connected, and can be slidably connected. The locking head 214 is arranged on one side of the locking rod 213 and is located at the end of the locking rod 213 away from the hanging rod 212. The brake rod 221 of the second brake assembly 22 is arranged on the side of the locking rod 213 away from the locking head 214, that is, the locking head 214 can be arranged on the side of the locking rod 213 away from the brake rod 221.

[0045] In one embodiment, the first brake assembly 21 may further include: a brake seat 216 and a first elastic member 215. The first elastic member 215 is disposed between the brake seat 216 and the space between the locking rod 213 and one end of the hanging rod 212. The hanging rod 212 can rotate along the connection between the hanging rod 212 and the locking rod 213 as the bearing portion 211 moves. At the same time, when the hanging rod 212 rotates, it is configured to push the locking rod 213 to move in a first direction, thereby pushing the first elastic member 215 to compress and move toward the brake seat 216. The first direction is the direction of use of the emergency escape device 2. When the locking rod 213 moves in the first direction, it can move close to the handrail track 1 or move to the outside of the handrail track 1, thereby limiting the position of the handrail track 1 and ensuring the safety of the handrail track 1 during use when connected to the emergency escape device 2. The first elastic member 215 can specifically be a spring, a shrapnel, etc., which is not limited in this application.

[0046] In one embodiment, the locking rod 213 may include a vertical portion 2131 and an extension portion 2132, wherein the extension portion 2132 is arranged at an end of the vertical portion 2131 close to the hanging rod 212, and the extension portion 2132 extends toward the second direction, and the surface of the extension portion 2132 away from the vertical portion 2131 contacts and is slidably connected to the end of the hanging rod 212 away from the bearing portion 211; wherein the second direction is arranged to cross the first direction, and specifically can be a direction perpendicular to the first direction.

[0047] In one embodiment, the outer side surface 21322 of the extension portion 2132 away from the vertical portion 2131 is an arcuate surface, or the end of the hanging rod 212 away from the bearing portion 211 has an arcuate surface, so that the contact surface between the extension portion 2132 and the hanging rod 212 is an arcuate contact surface, and the end of the hanging rod 212 away from the bearing portion 211 slides along the arcuate contact surface. That is, either the outer side surface 21322 of the extension portion 2132 away from the vertical portion 2131 or the end of the hanging rod 212 away from the bearing portion 211 can be an arcuate surface, or both can be arcuate surfaces, so that the end of the hanging rod 212 away from the bearing portion 211 slides along the outer side surface 21322 of the extension portion 2132 more smoothly, and the movement process is slow and uniform, thereby ensuring the safety and stability of the operation of the first brake assembly 21. Figure 4 The figure shows the structure of the brake locking system 20 of the present application in state B, wherein the locking rod 213 is in an upward position, and the second brake assembly 22 is still in the initial position. In other words, the first brake assembly 21 is in the locked state, and the second brake assembly 22 is not in the locked state.

[0048] In one embodiment, if Figure 2~Figure 3The figure shows the structure of the brake locking system 20 of the present application in its initial state A. The first elastic member 215 is disposed between the inner side surface 21321 of the extension portion 2132 and the bottom wall of the brake seat 216. The brake seat 216 is sleeved on the vertical portion 2131 and slidably connected thereto, allowing the locking rod 213 to move relative to the brake seat 216 in a first direction. In other words, one side of the brake seat 216 penetrates the vertical portion 2131, allowing the vertical portion 2131 to move relative to the brake seat 216 in the first direction. In this embodiment, the brake seat 216 is stationary, allowing for passive speed control during operation. The brake seat 216 may include two portions with stepped surfaces 2161. The taller portion is connected to the vertical portion 2131, while the shorter portion has a brake head 223 disposed on its upper surface and abuts against the first elastic member 215 on its lower surface. The brake head 223 disposed on the stepped surface 2161 may be connected to the brake seat 216 via a second bearing (not shown). In this embodiment, the second bearing remains stationary. In other embodiments, the brake seat 216 may be straight in the second direction, i.e., without the stepped surface 2161, or may have other structures, which are not limited in this application. It will be appreciated that in the initial state A, both the first brake assembly 21 and the second brake assembly 22 are unlocked.

[0049] In one embodiment, the second brake assembly 22 may include a brake lever 221, a lifting lever 222, and a brake head 223. One end of the brake lever 221 is rotatably connected to the hanging rod 212, thereby facilitating assembly and saving assembly space. The lifting lever 222 is configured to be pushed by the brake lever 221 to move up and down in a first direction when the brake lever 221 rotates. The brake head 223 is disposed on a side of the lifting lever 222 away from the hanging rod 212 and is coaxial with the lifting lever 222, so that when the lifting lever 222 moves up and down in the first direction, it further pushes the brake head 223 to move in the first direction, i.e., to move up and down in the first direction.

[0050] In one embodiment, the brake lever 221 may include a stop lever 2211 and a push portion 2212. The stop lever 2211 may be initially positioned parallel to the locking lever 213 along a first direction. During braking, the stop lever 2211 may rotate, for example, clockwise. The push portion 2212 is disposed at an end of the stop lever 2211 adjacent to the hanging rod 212. The stop lever 2211 and the push portion 2212 intersect via a third rotation axis 24 and are rotatably disposed such that the push portion 2212 is configured to move in opposite directions relative to the stop lever 2211. The stop lever 2211 may rotate along the third rotation axis 24 to move closer to or further away from the vertical portion 2131.

[0051] In one embodiment, the second brake assembly 22 may further include a second elastic portion 224, which is arranged between the brake head 223 and the pushing portion 2212, and the second elastic portion 224 is configured to be able to be compressed when the lifting rod 222 is lifted and lowered along the first direction, and approach the brake head 223. It can be understood that when the lifting rod 222 is initially in a lifting state, it is not compressed in the first direction, that is, it is in natural extension; wherein, the first elastic member 215 can specifically be a spring, a spring sheet, etc., and this application does not impose any restrictions on this.

[0052] The stop rod 2211 may further include a handle 2213, which is disposed on a side of the stop rod 2211 away from the pushing portion 2212 and is arranged crosswise with the stop rod, thereby facilitating the user to hold or grip the device, thereby improving the user experience. Figure 5 The figure shows the structure of the brake locking system 20 of the present application in state C. When the locking rod 213 and the second brake assembly 22 are both in the upward position, they can form a full-scale abutment or locking connection with the handrail track 1, improving the reliability of the connection between the handrail track 1 and the emergency escape device 2. At the same time, the handle 2213 is also moved away from the locking rod 213. When the brake locking system 20 is in state C, the upward movement of the locking rod 213 causes both the first brake assembly 21 and the second brake assembly 22 to be in the locked state, and the second brake assembly 22 is in the fully braked state.

[0053] In one embodiment, the lifting rod 222 may include: a sliding rod 2221 and an abutment portion 2222 connected to each other, wherein the cross-section of the abutment portion 2222 is larger than the cross-section of the sliding rod 2221, so that a portion of the abutment portion 2222 is clamped on the outer side surface 21322 of the extension portion 2132 of the locking rod 213, so that the extension portion 2132 slides along the sliding rod 2221 in the first direction, preventing the abutment portion 2222 from falling off from the extension portion 2132 during the lifting and lowering process of the lifting rod 222 along the first direction.

[0054] In one embodiment, the vertical portion 2131 and the extension portion 2132 are integrally formed or welded together; the stopper rod 2211 and the pusher portion 2212 are integrally formed or welded together; and the slide bar 2221 and the abutment portion 2222 are integrally formed or welded together. Preferably, all are integrally formed to facilitate preparation and assembly.

[0055] When using the escape device, the user wears the matching escape seat (not shown) in a standardized manner, hangs the escape seat strap (the strap must not be twisted or knotted) on the support portion 211 of the emergency escape device 2, and tightly connects the handrail track 1 to the emergency escape device 2. Pull the handle 2213 of the brake lever 221, sit down safely on the escape seat, and the support portion 211 will lift the locking rod 213. Release the handle 2213 of the brake lever 221, and the person can slide down the handrail track 1 at a constant speed, achieving rapid evacuation. During the descent, if encountering special circumstances, the user can pull the handle 2213 of the brake lever 221 by hand to brake and stop immediately. The use process is simple and convenient, highly safe, and highly effective, and can effectively achieve emergency escape.

[0056] The brake locking system 20 disclosed in the present application is used for an emergency escape device 2, comprising: a first brake assembly 21, the first brake assembly 21 comprising a bearing portion 211, a hanging rod 212, a locking rod 213 and a locking head 214, wherein the bearing portion 211 and the hanging rod 212 are movably connected, the hanging rod 212 and the locking rod 213 are movably connected, and the locking head 214 is arranged on one side of the locking rod 213 and is located at an end of the locking rod 213 away from the hanging rod 212; the first brake assembly 21 also comprises: a brake seat 216 The first elastic member 215 is disposed between the brake seat 216 and the space between the locking rod 213 and one end of the hanging rod 212. The hanging rod 212 can rotate along the connection between the hanging rod 212 and the locking rod 213 as the hanging rod 212 moves. At the same time, when the hanging rod 212 rotates, it is configured to push the locking rod 213 to move along a first direction, thereby pushing the first elastic member 215 to compress and move toward the brake seat 216. The first direction is the installation direction of the emergency escape device 2. The structural design of the brake locking system 20 of the present application allows the emergency escape device 2 to be braked at any time during use, greatly improving its safety. At the same time, the brake locking system 20 is simple to operate, has high braking stability, and can stop the vehicle immediately after braking, making it convenient to use.
