The second gear passes through a shaft and is positioned with the fixed plate. One end of the shaft protrudes from the other side of the fixed plate and passes through the third gear. The top teeth of the third gear connect with the Four gears, the fourth gear and the outer end of the shaft rod of the brake wheel are positioned; multiple pulleys are arranged side by side in the lower chamber of the casing, and the outer circumference is wound with cables, and the center of the pulley has a horizontal groove on the inner wall of the hole; The outer peripheral wall of the main shaft is provided with longitudinal slots matching the transverse holes of each pulley. A position control part is inserted into the longitudinal slot of the main shaft by a spring. The top of the spring is inserted into a latch. The main shaft is pierced with multiple pulleys, and the top end of the clamp enters the horizontal long groove in the central transverse hole of the pulley. One end of the main shaft is pivotally connected with the side wall of the casing, and the other end is pivotally connected with the fixed plate through the first gear. The deceleration lever in the lower chamber of the casing The bottom end is in conflict with the outer periphery of the pulley.

The utility model has the advantages that each pulley is respectively stressed and can rotate independently, and can be used by a plurality of escapees at the same time.

Detailed ways

As shown in Fig. 1 and Fig. 2, the utility model is made up of a fixed plate 20, a casing 30, a brake wheel 40, a reduction gear set, a plurality of pulleys 60 and 61 and a main shaft 70, wherein: on the fixed plate 20 There are multiple shaft holes 21; the casing 30 has a lower chamber 31 and an upper chamber 32, wherein the top wall 33 of the lower chamber 31 has several longitudinal perforations 34, and the tops of several deceleration rods 35 are inserted into the springs 36 and penetrate the longitudinal perforations 34 inside, the casing 30 is fixed on one side of the fixed plate 20; the brake wheel 40 is positioned inside the upper chamber 32 of the casing 30 through a shaft 41, and one end of the shaft 41 protrudes from the other side of the fixed plate 20; deceleration The gear set consists of a first gear 51 arranged inside the lower chamber 31 of the casing 30 and attached to one side of the fixed plate 20, and engages with the second gear 52 upwards. The second gear 52 passes through a shaft 53 and the fixed plate 20 Positioning, one end of the shaft 53 protrudes from the other side of the fixing plate 20 to pass through the third gear 54 , the top of which is geared to the fourth gear 55 , and the fourth gear 55 and the outer end of the shaft 41 of the brake wheel 40 pass through and set; A plurality of pulleys 60 and 61 are arranged side by side in the lower chamber 31 of the shell 30, and the outer periphery is wound with a rope 62, and the inner wall of the transverse hole 63 in the center of the pulleys 60 and 61 has a horizontal and long groove 64; the main shaft 70 is arranged laterally, and its outer periphery The wall is provided with the longitudinal slotted hole 71 that cooperates with the transverse hole 63 of each pulley 60 and 61, and a position control member 80 can be inserted respectively, and a spring 81 is inserted in the longitudinal slotted hole 71 of the main shaft 70, so that the spring 31 A clip 82 is inserted into the top end, and the top of the clip 82 has an inclined guide surface 83, so that the main shaft 70 passes through a plurality of pulleys 60 and 61, and the top of the clip 82 enters the horizontal long groove in the center of the pulleys 60 and 61 and crosses the hole 63. 64, another end of the main shaft 70 is pivotally connected to the side wall 37 of the housing 30, and the other end is pivotally connected to the fixed plate 20 through the first gear 51, and the bottom end of the deceleration lever 35 inside the lower chamber 31 of the housing 30 is connected to the Pulley 60 and 61 outer peripheries conflict.

As shown in Fig. 1, Fig. 2, Fig. 5 and Fig. 6, when the utility model is implemented, the main shaft 70 can be passed through the required number of pulleys 60 and 61 according to actual needs, when one of the pulleys 60 is supported by the cable When the pulling of 62 rotates, the horizontal long groove 64 in the center of the pulley 60 crosses the inner wall of the hole 63 to push the clamp 82 of the position control part 80 to rotate the main shaft 70. At this time, the other pulley 61 is not pulled by the rope 62, so the main shaft When the pulley 61 rotates, the fastening 82 inside the pulley 61 is retracted by the inclined guide surface 83 at the top to cross the long horizontal groove 64 due to the rotation of the main shaft 70, so that the pulley 61 does not move, but the main shaft 70 is lifted by the rotation of the other pulley 60, So an escaper uses a pulley 60, but can not drive another pulley 61 to rotate and rope 62 comes off, and two escapers can use two pulleys 60 and 61 to escape immediately without having to wait in line. Certainly the utility model can be implemented as more than three, four, or five pulleys. As long as part of the pulleys are used, the unused pulleys will not rotate under the control of the position control part 80. It is used by survivors and has excellent safety features.
