The specific embodiment
Referring to accompanying drawing, the invention will be further described.
See figures.1.and.2, dumbbell high-rise escape device of the present invention, respectively there is a deceleration device 28 at the two ends of central shaft 2, and each deceleration device 28 comprises the metal shell, the centrifugal deceleration device with steel ball, planetary gear automatic speed governing device of dumbbell shape, with steel wire rope draw off gear and this five part of emergency braking apparatus of unilateral bearing.
Wherein, the metal shell of dumbbell shape comprises: the central axle sleeve 1 of coaxial line device, the first shell 27, slip shell 25, second housing 23, end cap 18 and safety belt 30.Central axle sleeve 1 and the first shell 27 fix by holding screw, there are four 45 ° circle-arc teeth (as shown in Figure 5) at the left end face place of slip shell 25, cooperate with four the 45 ° arc grooves (as shown in Figure 4) on the first shell 27, four symmetrical straight pins 3 with Compress Spring are arranged in the middle of the first shell 27 and the slip shell 25, the outer surface of the first shell 27 has cannelure, this cannelure and second housing 23 forms safety belt mounting groove 24(as shown in figure 13) safety belt 30 is wrapped on the safety belt mounting groove 24, second housing 23 has slotted hole 11 as the outlet of steel wire rope 29, and end cap 18 and second housing 23 fix by screw.
Centrifugal deceleration device with steel ball comprises: be enclosed within central compressed spring 26, brake pad 4, four symmetrical steel balls 5 on the central shaft 2, steel ball baffle plate 6.Steel ball 5 radially slides between brake pad 4 and steel ball baffle plate 6, and is limited in four arc grooves in steel ball baffle plate 6 left sides, and the taper seat that brake pad 4 is relative with the first shell 27 provides the rubbing surface (as shown in figure 14) of frictional resistance.
The planetary gear automatic speed governing device comprises: the first wheel disc 22, planet circular system 7, three little axles 8 of symmetrical planetary gear and the second wheel disc 21.Centre wheel in the planet circular system 7 is inserted and secured on the end of central shaft 2, and insert in the first wheel disc 22 and the second wheel disc 21 respectively at the two ends of three little axles 8 of planetary gear, and the external toothing of planet circular system 7 fixes by holding screw and the first shell 27.
Steel wire rope draw off gear with unilateral bearing comprises: the second wheel disc 21, unilateral bearing 9, coiling wheel disc 20, end rotating disk 15 and steel wire rope 29.Unilateral bearing 9 is installed between the second wheel disc 21 and the coiling wheel disc 20, and steel wire rope 29 is wrapped in the winding slot 10 of coiling on the wheel disc 20, and end rotating disk 15 fixes by the outrigger shaft 16 of screw with the coiling wheel disc.
Emergency braking apparatus comprises: the first brake block 12, cover have screw 19, the second brake block 13, brake disc 14 and the brake bar 17 of spring.The conical surface that the first brake block 12 is relative with coiling wheel disc 20 is brake area (as shown in figure 16), the first brake block 12 and the second brake block 13 are all coaxial with the outrigger shaft 16 of coiling wheel disc, have two symmetrical covers that the screw 19 of spring is arranged between the first brake block 12 and the end cap 18, brake bar 17 is by in the screw thread precession brake disc 14.
The course of work of the present invention is as follows:
In daily life, the user can carry out the indoor body-building motion as dumbbell with the present invention, plays the effect that improves the health.
When high-rise life saving, the user need pull out steel wire rope 29 and it is hung over firm place, and brake bar 17 is installed, and slip slip shell 25 is pulled out safety belt 30 back ofs the body at back.
At first, in the decline process, steel wire rope 29 drives coiling wheel disc 20 and rotates, the rotation of coiling wheel disc 20 drives the rotation of the second wheel disc 21, thereby drives the rotation of planet circular system 7, and the rotation of planet circular system 7 drives central shaft 2 and rotates, central shaft 2 drives steel ball 5, steel ball baffle plate 6, brake pad 4 rotations, because the centrifugal action of steel ball 5, brake pad 4 compresses the interior rubbing surface of the first shell 27, produces and hinders the frictional resistance that rotates.After rotating speed reached certain value, the steel wire rope input power equated with frictional power loss, has realized uniform rotation.
Secondly, in braking procedure, the user holds brake bar 17 rolling brake dishes 14, brake disc 14 drives the second brake block 13 and rotates, hemispherical projections on the second brake block 13 conical surfaces stops the rotation of coiling wheel disc 20 with the conical surface of the first brake block 12 compression coiling wheel discs 20, realizes braking.
At last, in the process that reclaims steel wire rope, the user rotates end rotating disk 15, drives coiling wheel disc 20 backward rotation, because the effect of unilateral bearing 9 realizes that the convenient of steel wire rope 29 reclaims so that the second wheel disc 21 no longer rotates.
