DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific drawings.

[0031] Reference is made to Figure 1 , which shows the structure diagram of the rope stop safety rescue device 100 in the present example.

[0032] The rope stop safety rescue device 100 mainly includes a housing assembly 110 and a speed reduction friction block 120.

[0033] The housing assembly 110 here includes a fixed plate 111, a moving plate 112, a fixed switch 115 and a rope winding wheel 113.

[0034] Among them, the fixed plate 111 is provided with the rope winding wheel 113 at one end and the fixed switch 115 at the other end; the moving plate 112 is rotatably arranged on the rope winding wheel 113 at one end and can rotate relative to the fixed plate 111 around the rope winding wheel 113, and the other end of the moving plate 112 is provided with a hole position matched with the fixed switch 115.

[0035] The speed reduction friction block 120 is rotatably sleeved on the fixed switch 115 and can swing relative to the winding wheel 113 around the fixed switch 115. The speed reduction friction block 120 and the winding wheel 113 form a rope channel through which the rope 130 passes, and the rope channel changes with the rotation of the speed reduction friction block 120 around the fixed switch 115.

[0036] Specifically, the speed reduction friction block 120 includes a circular surface 123 and a working surface 124, and the working surface 124 is in the shape of an involute relative to the rotation center axis of the speed reduction friction block.

[0037] The contact between the circular surface 123 and the rope 130 is smooth, facilitating the sliding of the rope stopping safety rescue device 100 along the rope 130.

[0038] The working surface 124 is provided with a one-way speed reduction tooth 124a, and the one-way speed reduction tooth 124a is arranged in a direction such that the rope stopping safety rescue device 100 generates a friction force on the rope 130 when sliding downward along the rope 130.

[0039] With the above structure, when the speed reduction friction block 120 is opened, the rope channel formed between the speed reduction friction block 120 and the winding wheel 113 allows the rope stopping safety rescue device 100 to smoothly slide along the rope 130.

[0040] When there is no action, the speed reduction friction block 120 will automatically swing downward due to gravity, and the rope channel between the speed reduction friction block 120 and the winding wheel 113 becomes smaller.

[0041] On the other hand, the one-way speed reduction tooth 124a on the speed reduction friction block 120 generates a friction force on the rope 130 when in contact with the rope 130. The greater the downward movement of the rope stopping safety rescue device 100, the greater the friction force of the one-way speed reduction tooth 124a on the rope 130. Under the interaction of the two, the rope stopping safety rescue device 100 will automatically stop moving.

[0042] Specifically, the edge of the one-way speed reduction tooth 124a is smooth and has no sharp corners, which is to protect the rope in contact with it.

[0043] Furthermore, the speed reduction friction block 120 is also provided with a speed reduction friction block pull rope 121, as shown in the figure, when in use, the mobile version 112 is opened, and the speed reduction friction block 120 is rotated away from the winding wheel 113 by pulling the speed reduction friction block pull rope 121, so that the rope channel formed by the speed reduction friction block 120 and the winding wheel 113 becomes larger, and the rope 130 is placed in the rope channel. Figure 2

[0044] After the rope 130 is placed, as shown in the figure, the mobile version 112 is closed, and the speed reduction friction block 120 is rotated toward the winding wheel 113 by pulling the speed reduction friction block pull rope 121, so that the rope channel formed by the speed reduction friction block 120 and the winding wheel 113 becomes smaller, and the rope stopping safety rescue device 100 is prevented from sliding downward along the rope 130. Figure 3 ​As shown, the mobile plate 112 is rotated around the rope wheel 113 to close.

[0045] Further, the speed reduction friction block 120 is also provided with a process hole 125, which can reduce the weight of the rope stop safety rescue device 100 and enhance the stability of the device. The shape of the process hole 125 can be set according to specific conditions, which will not be repeated here.

[0046] As shown, the fixed plate 111 in the present example is also provided with a fixed switch 115 that can be extended up and down, which is used to fix the mobile plate 112. Figure 4

[0047] The fixed switch 115 includes a pressing fixed shaft 116, a pressing fixed shaft shell 116a, a spring 117 and a pressing surface 118.

[0048] The pressing fixed shaft shell 116a is screwed on the fixed plate 111 by a nut, and the spring 117 is arranged in the pressing fixed shaft shell 116a.

[0049] The pressing fixed shaft 116 is arranged in the pressing fixed shaft shell 116a through the spring 117, and the top of the pressing fixed shaft 116 is also provided with the pressing surface 118, which is convenient for the operator to press.

[0050] Further, the mobile plate 112 is provided with a second hole position 119 matched with the fixed switch 115.

[0051] The fixed switch 115 arranged in such a structure, in specific application, first press the fixed shaft 116, rotate the mobile plate 112 around the rope wheel 113, when the second hole position 119 on the mobile plate 112 rotates to the corresponding position of the fixed switch 115, release the fixed switch 115, the fixed switch 115 pops up and can be clamped into the corresponding second hole position 119 on the mobile plate 112, fixing the mobile plate 112.

[0052] After pressing the fixed switch 115 again, the mobile plate 112 can be rotated around the rope wheel 113 to open.

[0053] Press the fixed switch 115, rotate the mobile plate 112 clockwise, and the safety hook can be connected with the first hole position 114.

[0054] Further, the mobile plate 112 in the present example is also provided with a second limiting groove 112a, which is used to limit the rotation angle of the mobile plate 112.

[0055] Further, a baffle 140 is arranged on the fixed plate 111 in the rotation path of the mobile plate 112, which can cooperate with the second limiting groove 112a to limit the mobile plate 112.

[0056] ​Further, as shown in Figure 1 and Figure 5 The limiting pin shaft 122 is arranged on the speed reduction friction block 120 to ensure that the speed reduction friction block 120 rotates within a limited angle.

[0057] Specifically, the first limiting groove 111a is arranged on the fixed plate 111 to cooperate with the limiting pin shaft 122, and the cooperation of the two can ensure that the speed reduction friction block 120 rotates within a limited angle.

[0058] In addition, the shell assembly 110 is also provided with a structure connected to the operator connection unit.

[0059] Specifically, the first hole 114 is arranged on the rope winding wheel 113 at the connecting end of the fixed plate 111 and the moving plate 112 to be connected to the operator connection unit.

[0060] In addition, the speed reduction friction block 120 in the present example is arranged to rotate by being sleeved on the pressing fixed shaft shell 116a.

[0061] Referring to Figure 5 , the rope stopping safety rescue device 100 arranged based on the above structure can be freely slid along the rope 130 when applied in specific applications. First, the fixed switch 115 is pressed, the moving plate 112 is opened, the rope 130 is inserted into the rope channel formed by the speed reduction friction block 120 and the rope winding wheel 113, the moving plate 112 is closed, and the speed reduction friction block rope 121 is pulled up. At this time, the friction force exerted by the speed reduction friction block 120 on the rope 130 is reduced or disappears, and the rope stopping safety rescue device 100 can freely slide along the rope 130.

[0062] When there is no action, the speed reduction friction block 120 will automatically swing downward due to the action of gravity, so that the rope channel between the speed reduction friction block 120 and the rope winding wheel 113 becomes smaller.

[0063] On the other hand, the one-way speed reduction tooth 124a on the action surface of the speed reduction friction block 120 is in contact with the rope 130 to generate resistance to the rope 130. The greater the friction force of the one-way speed reduction tooth 124a on the rope 130, the more the rope stopping safety rescue device 100 moves downward. Under the interaction of the two, the rope stopping safety rescue device 100 will automatically stop moving.

[0064] The rope stopping safety rescue device provided by the present application can adjust the size of the rope channel through the speed reduction friction block arranged in the shell assembly, and can gradually increase the friction force on the rope located therein. The rope stopping safety rescue device can realize the functions of stopping falling, dragging, lifting heavy objects, escaping and self-rescue, emergency rescue, and panic stopping, and the operator can freely control it to ensure the efficiency and safety of personal travel and rescue.

[0065] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
