As will be described in detail below.

The cantilever 1 may be provided at a front end thereof on a stand 11 standing on the ground and at a rear end thereof suspended outside an escape opening 101 such as a window or a balcony for hanging the chain 2. The cantilever 1 can also be embedded directly in a wall (not shown) around the exit 101, so as to save the indoor space. In addition, the user can arrange the cantilevers on the peripheries of the escape exits, when the situation occurs, the safer escape exits can be selected firstly according to the field situation, then the chains are hung on the cantilevers, and then the cantilevers are matched with other structures to move to the preset escape position.

The chain 2 may be a steel chain or an eel chain, which is matched with the gear disc 5 and has a predetermined length, and may be extended from the escape exit to a predetermined escape position such as an open space of a ground or a lower floor to support a human body, and a chain for supporting a plurality of people may be selected according to a use situation.

As shown in fig. 2, the frame 3 is substantially square and hollow, and has a front rod 31, two side rods 32 and a rear rod 33, which are sleeved outside the chain 2 for installing the pivot 4, the gear plate 5, the safety belt 6 and the brake structure 7, and for clamping the chain 2 and the gear plate 5 together; the front rod 31 at the front side thereof may be provided with a roller 34 rolling along the chain 2 to move up and down along the chain 2.

The pivot 4 is laterally inserted on the two side rods 32 of the frame 3 and is located behind the chain 2 for the arrangement of the toothed disc 5.

The gear plate 5 is pivotally mounted on the pivot shaft 4 in cooperation with a ball bearing (not shown) and is located in the frame 3 and is rollably engaged with the chain 2 for transferring the weight of a user wearing a safety belt to the chain 2.

As shown in fig. 1, a safety belt 6 is attached to the frame 3 for supporting a user. A snap ring 35 may be further provided outside the rear side of the frame 3 to facilitate the installation of the safety belt 6 and to prevent the safety belt from interfering with the gear plate 5.

The braking structure 7 is disposed on the frame 3 for controlling the rolling speed of the gear plate 5 to stop the user 103 from descending, and a structure such as a braking structure (not shown) of a bicycle can be used to slow down or stop the rotation of the rotating plate to control the descending speed of the user, as described below.

As shown in fig. 3, the aforementioned pivot 4 may be a hollow body to be matched with the brake structure 7, and the brake structure 7 includes: two swing levers 71, the rear ends of which are respectively swingably provided on the frame 3, and the front ends of which are respectively suspended on both sides of the pivot 4; two rod bodies 72 respectively inserted on the two side rods 32 in a transversely sliding manner, the corresponding outer ends are respectively fixed on the swinging rods 71, and the corresponding inner ends respectively penetrate through the two side rods 32 and are suspended on the two sides of the gear plate 5; two seat bodies 73 respectively arranged at the inner ends of the two rod bodies 72; two brake pads 74 respectively arranged on the two seat bodies 73 and located on two sides of the gear plate 5; a wire 75, one end of which is fixed on a swing rod 71, and the other end of which passes through the center of the pivot 4, extends out of the other swing rod 71, and then extends to a wire outer part 751 with a predetermined length; a sleeve 76, which is coated outside the wire body 751, and the top end of which is arranged on the swinging rod 71; an annular body 77 disposed at the end of the sleeve 76, the inner side surface of which has two corresponding sliding grooves 771 (as shown in fig. 4), and one side of the sliding grooves 771 has a plurality of grooves 772 (as shown in fig. 4); a control rod 78, both ends of which are slidably engaged in the sliding grooves 771 of the annular body and can be engaged in the grooves 772 of the annular body, respectively, the end of the wire body outer part 751 is connected to the control rod 78, as will be described in the following with reference to the continuous operation.

Fig. 5 to 7 are continuous operation diagrams of the brake structure 7, and for convenience of description, it is defined that a portion of the chute 771 of the annular body close to the sleeve 76 is a first dead point 773, and a portion far from the sleeve 76 is a second dead point 774, as shown in fig. 5, when the control lever 78 is located at the first dead point 773, the two brake pads 74 are not close to the gear plate 5, and at this time, the gear plate 5 can roll rapidly. As shown in fig. 6, when the control rod 78 gradually moves to the second dead point 774, the two swing rods 71 are driven by the wire 75 to move closer to each other, so that the two brake pads 74 contact the gear plate 5 to generate friction force, thereby achieving the effect of reducing the rolling speed of the gear plate 5. As shown in fig. 7, when the control lever 78 is located at the second dead point 774, the brake pads 74 clamp the gear plate 5, so that the gear plate 5 is in a non-rolling state. In addition, a spring (not shown) may be disposed between the swing lever 71 and the side bar 32, and when the control lever 78 gradually moves to the second dead point 774, the spring is compressed to generate a pre-force, so that when the control lever 78 approaches to the first dead point 773, the spring pushes the swing lever 71 open, and the brake pad 74 leaves the gear plate 5, and as shown in fig. 3 to 4, the groove 772 of the annular body may be inclined, and when the control lever 78 is clamped in the groove 772 of the annular body, the wire 75 may generate a pulling force to the control lever 78 by the pre-force of the spring, so that the control lever 78 is clamped at the bottom of the groove 772 of the annular body.

Through the combination of the above elements, when a condition occurs, the user can perform the following escape actions: 1. hanging the chain 2 on the cantilever 1; 2. the chain 2 is put down to enable the bottom end of the chain to extend to a preset escape position; 3. the safety belt 6 is tied on the body; 4. the gear disc 5 is in a non-rolling state by using the brake structure 7; 5. strides out of the escape exit 101; 6. the brake structure 7 is appropriately controlled to be lowered to a predetermined escape position, so that the escape from a high place can be quickly and safely performed. However, the escape operation is only a possible situation, and in fact, the brake structure 7 may be configured to make the gear plate 5 in a slow rolling or non-rolling state under normal conditions, so as to avoid the problem that the user forgets to press the brake structure 7 first in an emergency, which causes the user to slide down quickly.

As a second embodiment shown in fig. 8, the frame 8 may be a combined frame, and as will be illustrated below, the frame 8 includes: a front frame 81, generally U-shaped, covering the front side of the chain 2 and having a first end 83 and a second end 85; and a rear frame 91, generally U-shaped, having a third end 93 and a fourth end 95, wherein the third end 93 is pivotally connected to the first end 83, and the fourth end 95 is detachably connected to the second end 85, so that the frame can be disassembled for storage when not in use, and the user can wear a set of frames 8 respectively and combine the frames 8 on the chain 2 in sequence when the situation occurs, thereby being capable of being used by multiple users.

The structure of the front frame 81 and the rear frame 91 will now be described. As shown in fig. 9, the first end 83 and the third end 93 may have a corresponding recess 831 and a corresponding protrusion 931, and after the recess 831 and the protrusion 931 are engaged together, they are serially connected together by a rotating shaft 832, so that the front frame 81 and the rear frame 91 can swing with each other. As shown in fig. 10, the second end 85 and the fourth end 95 may have a front buckle portion 851 and a rear buckle portion 951 corresponding to each other, the front buckle portion 851 and the rear buckle portion 951 may be buckled together, and a positioning member 952 may be further disposed at an end of the rear buckle portion 951 and may pass through the second end 85, and a hole 953 is formed at a position where the end of the positioning member 952 protrudes from the second end for positioning by a pin 954.
