Description

Technical Field

[0001] The invention relates to the technical field of escape devices, and in particular to a descending mechanism of an escape basket. Background Art

[0002] In emergency situations such as fires and earthquakes, safe and effective escape equipment is essential. Some existing escape basket descending devices have a relatively complex structure, and usually require the connection of hanging wires for releasing wires to the frames on both the front and rear sides of the escape basket to achieve the descending function. For example, a patent document with publication number CN219764330U discloses a guardrail with an escape function. This not only increases the cost and installation difficulty of the equipment, but also may cause problems such as asynchronous release of wires on both sides in actual use, resulting in unstable descent of the escape basket. At the same time, during the descent process, if the front and rear sides are unevenly stressed, the escape basket is prone to flipping, seriously threatening the life safety of the user.

[0023] Reference Figures 1 to 6A descending mechanism of an escape basket includes an escape basket 1 and a hanging wire 2 for suspending the escape basket 1, the other end of the hanging wire 2 being fixed on a wall to suspend the escape basket 1. The escape basket 1 includes a first fixed frame 11 and a second fixed frame 12 respectively arranged on the front and rear sides, the hanging wire 2 includes a first hanging wire 21 arranged on the left side of the first fixed frame 11, and a second hanging wire 22 arranged on the right side of the first fixed frame 11, a storage device 3 for storing the first hanging wire 21 and the second hanging wire 22 is provided in the first fixed frame 11, a wire releasing device 4 is provided on the first fixed frame 11, and a balance support component 5 is provided on the first hanging wire 21 and the second hanging wire 22 to enable the escape basket 1 to descend smoothly. In this way, the suspension wire 2 is only stored at the front side or the rear side of the escape basket 1, and it is not necessary to connect the suspension wire 2 for releasing the wire to both the first fixed frame 11 and the second fixed frame 12 of the escape basket 1, which is enough to make the escape basket 1 descend, and the structure is simpler; at the same time, through the provided balancing support assembly 5, the escape basket 1 will not be overturned due to the force concentrated on one side of the first fixed frame 11 during the descent process, thereby ensuring the safety performance of the escape basket 1 during the descent process, so that it can descend smoothly.

[0024] Reference Figures 1 to 3 In the present embodiment, a connecting rod 13 is provided between the first fixed frame 11 and the second fixed frame 12 to connect the two. The balancing support assembly 5 includes a support member 51 arranged above the first fixed frame 11, a first traction line 52 arranged on the support member 51 and the other end of which is fixed on the first fixed frame 11, a second traction line 53 arranged on the support member 51 and the other end of which is fixed on the second fixed frame 12, and a third traction line 54 arranged on the support member 51 and the other end of which is fixed on the connecting rod 13. The first traction line 52 and the second traction line 53 can be fixed to the first fixed frame 11 by connecting a connector through a threaded connection. Similarly, the third traction line 54 can be fixed to the connecting rod 13 in the same manner. The first suspension line 21 and the second suspension line 22 are both wrapped around the support member 51 for at least one circle. In this way, the first traction line 53 and the second traction line 54 are used to balance the force acting on the escape basket 1 in the horizontal direction to prevent the escape basket 1 from turning over. At the same time, the third traction line 54 is used to limit the height position of the support member 51, so that the first traction line 53 and the second traction line 54 are both in a straightened state to avoid uneven force on one side.

[0025] Reference Figure 2 and Figure 3In this solution, the support member 51 includes a support block 511 and a pulley 512 disposed at the upper end of the support block 511. The first traction line 52, the second traction line 53 and the third traction line 54 are all disposed at the lower end of the support block 511. The first suspension line 21 and the second suspension line 22 are both wound around the pulley 512 at least once, so as to facilitate the release of the first suspension line 21 and the second suspension line 22 without jamming. Furthermore, the first traction line 52 and the second traction line 53 are symmetrically arranged with respect to the third traction line 54, and the third traction line 54 is located on the symmetric plane between the first fixed frame 11 and the second fixed frame 12.

Further, the first winding shaft 32 is provided with a first thread groove 321 for winding up the first suspension wire 21, the second winding shaft 34 is provided with a second thread groove 341 for winding up the second suspension wire 22, and the rotation direction of the first thread groove 321 is opposite to the rotation direction of the second thread groove 341. In this way, the first suspension wire 21 and the second suspension wire 22 are arranged and stored so that they can be released smoothly without getting stuck.

[0027] Reference Figure 4 and Figure 6In this solution, the wire-releasing device 4 includes a housing 41 disposed on the first fixed frame 11 and located at the coupling 35, a manual wire-releasing structure 42 disposed on the housing 41 and used to synchronously release the first suspension wire 21 and the second suspension wire 22, and a speed limiter 43 that can limit the wire-releasing speed of the first suspension wire 21 and the second suspension wire 22. Further, the manual wire-releasing structure 42 includes a first limit block 421 disposed on the coupling 35, a threaded shaft 422 disposed in the housing 41, a rotating handle 423 disposed on the housing 41 and driving the threaded shaft 422 to rotate, and a second limit block 424 disposed on the threaded shaft 422 and reciprocating along the axial direction of the threaded shaft 422 to engage with the first limit block 421. Specifically, the first limit block 421 is in the shape of a water drop, and the second limit block 424 includes a recessed portion 4241 that can abut against the protruding portion of the first limit block 421. In this way, the first suspension line 21 and the second suspension line 22 are manually controlled to release synchronously, ensuring that the escape basket 1 descends smoothly; the operation is simple and convenient, and the use of electrical control components is avoided, which is safer and more reliable. In addition, the speed limiter 43 is provided to prevent the escape basket 1 from decreasing too quickly, further improving the safety performance.

[0028] Reference Figure 4 In this embodiment, the speed limiter 43 includes a damper 431 arranged at the ends of the first winding shaft 32 and the second winding shaft 34, so that the rotation speed of the first winding shaft 32 and the second winding shaft 34 can be limited by the damper 431, thereby limiting the speed of the first suspension line 21 and the second suspension line 22 to be released.
