[0017] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0018] like Figures 1 to 4 As shown, this application embodiment provides a multi-person high-rise escape device, including a rope releaser 1, a steel wire rope 2, and a descent device 3. The steel wire rope 2 is wound around the rope releaser 1, and the rope releaser 1 is used to release the steel wire rope 2. The decelerator 3 includes a first deceleration component 31, a second deceleration component 32, and a locking component 33. The first deceleration component 31 includes a first housing 311, a hook 312, and a plurality of first wheels 313. The first housing 311 is provided with a first receiving groove 3111. The plurality of first wheels 313 are rotatably installed in the first receiving groove 3111 at intervals. The hook 312 is installed on the first housing 311. The second slow-descent assembly 32 includes a second housing 321, a second friction plate 322, an adjusting member 323, and a plurality of second wheels 324. The second housing 321 is provided with a second receiving groove 3211 and a side opening 3212 communicating with the second receiving groove 3211. The plurality of second wheels 324 are rotatably mounted in the second receiving groove 3211 at intervals. The second friction plate 322 is slidably mounted in the second receiving groove 3211. The adjusting member 323 is mounted on the second housing 321 and connected to the second friction plate 322. The first housing 311 is rotatably mounted on the second housing 321, and the locking component 33 is mounted on the first housing 311 and / or the second housing 321; When the decelerator 3 is in the closed state, the second housing 321 is inserted into the receiving groove, the first wheel 313 and the second wheel 324 are alternately distributed, the wire rope 2 passes through the side opening 3212 and extends into the first receiving groove 3111 and the second receiving groove 3211, and the wire rope 2 passes around the first wheel 313 and the second wheel 324. The locking assembly 33 is used to lock the first housing 311 and the second housing 321. The adjusting member 323 is used to drive the second friction plate 322 to move towards or away from the second wheel 324, so as to adjust the friction between the wire rope 2 and the decelerator 3.

[0019] The steel wire rope 2 includes, but is not limited to, steel wire ropes and ropes; the rope releaser 1 can be a manual releaser, an electric releaser, etc.; the number of the first wheel 313 and the second wheel 324 can be set according to actual needs, for example, two or three first wheel 313 and three second wheel 324; the locking assembly 33 can be installed on the first housing 311 or the second housing 321; the locking assembly 33 includes, but is not limited to, locking pins 332 and locking buckles; the first receiving groove 3111 extends vertically through the first housing 311, the second receiving groove 3211 extends vertically through the second housing 321, and the side opening 3212 is located on the side of the second housing 321. The first housing 311 and the second housing 321 can be in an open state, and the maximum angle between the first housing 311 and the second housing 321 is 90 degrees.

[0020] Specifically, the rope release device 1 releases the steel wire rope 2 outside the high-rise building, the descent device 3 is opened, and the steel wire rope 2 extends into the second receiving groove 3211 through the side opening 3212; the descent device 3 is closed, the second housing 321 is inserted into the first receiving groove 3111 of the first housing 311, the first wheel 313 and the second wheel 324 are alternately distributed, and the steel wire rope 2 passes around the first wheel 313 and the second wheel 324, one side of the steel wire rope 2 abuts against the first wheel 313 and the second wheel 324, and the other side of the steel wire rope 2 abuts against the second friction plate 322; the escapee is tied with straps, and the straps are suspended... The hook is engaged with the hook 312; the escapee operates the adjusting component 323, which is used to move the second friction plate 322 toward or away from the second wheel 324. When the second friction plate 322 moves toward the second wheel 324, the friction between the wire rope 2 and the descent device 3 is greater, and the descent device 3 can remain stationary on the wire rope 2, or the descent device 3 moves at a lower speed along the wire rope 2. When the second friction plate 322 moves away from the second wheel 324, the friction between the wire rope 2 and the descent device 3 is less, and the descent device 3 moves at a higher speed along the wire rope 2.

[0021] In this invention, the steel wire rope 2 can be equipped with multiple descent devices 3, thus enabling this multi-person high-rise escape device to meet the needs of multiple people escaping from high-rise buildings. The steel wire rope 2 can be installed on the descent devices 3 through the side opening 3212. This multi-person high-rise escape device is easy to operate, allowing escapees to complete the high-altitude descent without having to hold onto the steel wire rope 2, making it suitable for different groups of people. Furthermore, the descent speed of the escapees along the steel wire rope 2 can be adjusted by the adjusting component 323, thus making the descent speed of this multi-person high-rise escape device adjustable.

[0022] In one embodiment, such as Figures 2 to 4 As shown, the second descent assembly 32 also includes a rope locking member 325 movably mounted on the second housing 321, and the locking part of the rope locking member 325 is located in the second receiving groove 3211; When the decelerator 3 is in the closed state, the locking part extends between the first wheel 313 and the second wheel 324 and presses the wire rope 2. The rope locking member 325 is used to lock the wire rope 2 onto the decelerator 3. When the locking part separates (or releases) from the wire rope 2 between the first wheel 313 and the second wheel 324, the decelerator 3 can move along the wire rope 2.

[0023] The locking rope component 325 includes, but is not limited to, bolts; the gap between adjacent first wheel body 313 and second wheel body 324 is small.

[0024] Specifically, when the locking rope component 325 presses the wire rope 2 between the first wheel body 313 and the second wheel body 324, the decelerator 3 cannot move along the wire rope 2; when the locking rope component 325 releases the wire rope 2 between the first wheel body 313 and the second wheel body 324, the decelerator 3 can move along the wire rope 2. The friction between the wire rope 2 and the decelerator 3 can be adjusted by the adjusting component 323, that is, the speed at which the decelerator 3 moves along the wire rope 2 can be adjusted.

[0025] In this embodiment, the rope locking component 325 can lock the descent device 3 onto the steel wire rope 2, thereby improving the safety of the multi-person high-rise escape device.

[0026] In one embodiment, such as Figures 2 to 4 As shown, each of the first wheel bodies 313 is rotatably mounted in the first receiving groove 3111 via a first shaft; each of the second wheel bodies 324 is rotatably mounted in the second receiving groove 3211 via a second shaft; The second box body 321 is also provided with a plurality of notches and grooves 3213 spaced apart; When the decelerator 3 is in the closed state, the second box 321 is inserted into the first receiving groove 3111, and the first shaft passes through the notch groove 3213 one by one.

[0027] In this embodiment, when the second box 321 is inserted into the first receiving groove 3111 of the first box 311, the notch groove 3213 can avoid the first shaft, so that the first wheel 313 and the second wheel 324 can be distributed vertically at intervals, ensuring the stability of the decelerator 3 when it is closed.

[0028] In one embodiment, such as Figure 1 As shown, the locking assembly 33 includes a locking ring 331 and a locking pin 332. The locking ring 331 is mounted on the second housing 321. The locking ring 331 has a first locking hole, and the first housing 311 has a second locking hole 3112. The locking pin 332 is inserted into the first locking hole and the second locking hole 3112 to lock the decelerator 3 in the closed state.

[0029] When the first descent component 31 and the second descent component 32 are combined, the locking pin 332 is inserted into the first locking hole and the second locking hole 3112, and the first descent component 31 and the second descent component 32 will not open, thereby ensuring the stability of the descent device 3 in the closed state and improving the safety of the multi-person high-rise escape device.

[0030] In one embodiment, such as Figure 4 As shown, the adjusting component 323 includes a crank 3231, a screw 3232, and a pressure block 3233; the locking ring 331 is provided with a threaded hole that is adapted to the screw 3232; The screw 3232 is threaded into the threaded hole, the crank 3231 is mounted on the screw 3232, the pressure block 3233 is mounted on the end of the screw 3232 away from the crank 3231, and the side of the pressure block 3233 away from the screw 3232 is connected to the second friction plate 322.

[0031] Specifically, the escapee rotates the hand crank 3231, which drives the screw 3232 to rotate. The screw 3232, through the pressure block 3233, drives the second friction plate 322 to move toward or away from the second wheel 324, thereby adjusting the friction between the wire rope 2 and the descent device 3.

[0032] In this embodiment, the adjusting component 323 has a simple structure and is easy to operate.

[0033] In one embodiment, such as Figure 4 As shown, the first descent assembly 31 further includes a first friction plate 314 installed in the first receiving groove 3111, and the first friction plate 314 is disposed opposite to the first wheel body 313.

[0034] Specifically, when the decelerator 3 is in the closed state, the steel wire rope 2 that passes around the second wheel 324 abuts against the second friction plate 322, thereby increasing the friction between the steel wire rope 2 and the decelerator 3 by the first friction plate 314, ensuring the stability of the decelerator 3 moving along the steel wire rope 2.

[0035] In one embodiment, such as Figure 1 As shown, the multi-person high-rise escape device also includes a support assembly 4, which includes a support top rod 41, a support bottom rod 42, a support screw 43, a hanging rod 44, and a fixed pulley 45 installed on the hanging rod 44; The support screw 43 is provided with a first external thread section 431 and a second external thread section 432 that are spaced apart, and the threads of the first external thread section 431 and the second external thread section 432 have opposite directions. The support top rod 41 is provided with a first internal threaded hole adapted to the first external threaded section 431, and the support bottom rod 42 is provided with a second internal threaded hole adapted to the second external threaded section 432. The bottom of the support rod 41 is threaded into the first internal threaded hole, and the top of the support rod 42 is threaded into the second internal threaded hole. The boom 44 is detachably inserted into the support top rod 41, and the wire rope 2 released by the rope releaser 1 passes around the fixed pulley 45.

[0036] In this configuration, one of the first threaded section and the other of the second threaded section is a left-hand external thread and the other is a right-hand external thread; the lifting rod 44 can be fixedly installed on the supporting top rod 41 by screws, bolts, etc.

[0037] Specifically, by rotating the support screw 43, the support screw 43 can drive the support top rod 41 and the support bottom rod 42 to move closer or further apart, thereby adjusting the height of the support assembly 4.

[0038] In this embodiment, the support assembly 4 is installed indoors, the boom 44 extends the fixed pulley 45 outside, and the rope release device 1 allows the steel wire rope 2 to pass over the fixed pulley 45 and suspend outside. Escapees descend slowly along the steel wire rope 2 using the descent device 3. Furthermore, the height of the support assembly 4 is adjustable, allowing it to be installed at different indoor heights, thus improving the applicability and versatility of this multi-person high-rise escape device.

[0039] Furthermore, the support assembly 4 can also be installed on a balcony; when the multi-person high-rise escape device is not applicable, the hanging rod 44 can be removed from the support top rod 41 and placed inside the house; when in use, the hanging rod 44 is then installed on the support top rod 41.

[0040] In one embodiment, such as Figure 1 As shown, the multi-person high-rise escape device also includes a ladder 5 installed on the support base rod 42.

[0041] Since windows, railings, etc. are at a certain height, it is not easy for escapers to hang on the descent device 3 located outside the building. In this case, escapers can use the stairs 5 to hang themselves on the descent device 3 outside the building.

[0042] In one embodiment, such as Figure 1 As shown, the support assembly 4 also includes a handle 46 mounted on the support screw 43.

[0043] In this embodiment, the operator can adjust the height of the support assembly 4 by rotating the support screw 43 through the handle 46, thereby improving the ease of adjustment of the support assembly 4.

[0044] In one embodiment, such as Figure 1 As shown, the rope releaser 1 is mounted on the support base rod 42.

[0045] In this embodiment, the ladder 5 and the rope releaser 1 are both installed on the support base 42, which facilitates the installation and transportation of this multi-person high-rise escape device.
