The lower surface of permanent magnet two-stage ring platform 2-1-2 is connected with the upper surface of friction eceleration mechanism 4. Retainer ring 3 is connected in the inwall stage casing of cylinder 1-1, and is positioned at the lower section of handle installing port 1-1-2.
Friction eceleration mechanism 4 includes four ferrum gripping sleeve 4-1, the cross section of ferrum gripping sleeve 4-1 is fan-shaped, its upper semisection is the quadrant cone 4-1-1 stood upside down, its lower semisection is quadrant cylinder 4-1-3, is provided with the gathering sill slideway 4-1-4 along coning angle direction on the outside conical surface of quadrant cone 4-1-1. The circular cone drift angle of the outside conical surface of quadrant cone 4-1-1 is 60 ��, and the angle of gathering sill slideway 4-1-4 and horizontal plane is 30 ��. The quadrant cambered surface 4-1-2 that internal diameter is up/down perforation of ferrum gripping sleeve 4-1. Four ferrum gripping sleeve 4-1 splits bringing together, and surround one friction eceleration sleeve of formation.
Gradient guide rail mechanism 5 includes integrated base 5-3, vertical bearing 5-2 and slide block guide rail 5-1, slide block guide rail 5-1 mates with gathering sill slideway 4-1-4 and is slidably connected, the lateral wall of vertical bearing 5-2 is arc surface, and the bonding of its blend compounds tangent with the medial wall of cylinder 1-1 is connected or welds and is connected.

Downhill race rope 9 is sequentially through downhill race rope positioning through hole 1-1-1, down pressure jacking mechanism 2, retainer ring 3, friction eceleration mechanism 4, bottom end cover 6.
During concrete application prompt drop deceleration lockset of the present utility model, can be used for the training of the prompt drop of fire fighter, it is also possible to as the challenge athletic competition in variety entertainment program, the willpower of experience and tempering people and courage and insight. Operator is suspended in below outer layer sleeve 1 by safety rope 8, holds lever 1-2 with one hand, and to utilize downhill race rope 9 be certain slope downslide from eminence. Original state as it is shown in figure 9, applied pulling force upwards by extension spring 2-2 to the upper surface of lower platen 2-1, and drives the one-level disc 2-1-1 of lower platen 2-1 to depart from retainer ring 3 upper surface; The permanent magnet two-stage ring platform 2-1-2 of lower platen 2-1 passes through four ferrum gripping sleeve 4-1 of magnetic-adsorption, and drive its respective gathering sill slideway 4-1-4 along self-corresponding slide block guide rail 5-1 simultaneously along moving to radial outside with edge straight up, so that the friction eceleration sleeve that four ferrum gripping sleeve 4-1 surround formation is separated from one another, and loosen the clamping pressure to downhill race rope 9.In the case, the upper surface of lower platen 2-1 is not applied pressure by top pressure circular arc termination 7-1, and outer layer sleeve 1 is in relative state slidably with downhill race rope 9. Operator glides prompt drop along downhill race rope 9 under gravity.
When needs apply brake force deceleration, as shown in Figure 3, operator directly presses lax handle 7 with the thumb on hand of the lever 1-2 that holds with a firm grip, now, lax handle 7 rotates around handle free bearing 1-4, its top pressure circular arc termination 7-1 oppresses downwards the upper surface of lower platen 2-1, the downward pressure that top pressure circular arc termination 7-1 applies is amplified under the leverage of free bearing and respectively overcomes pulling force and the permanent magnet two-stage ring platform 2-1-2 magnetic force to four ferrum gripping sleeve 4-1 of extension spring 2-2, thus downforce is applied simultaneously to be surrounded by four ferrum gripping sleeve 4-1 the upper surface of the friction eceleration sleeve formed by permanent magnet two-stage ring platform 2-1-2. this downward pressure will force gathering sill slideway 4-1-4 to move to radially inner side with edge downwards along slide block guide rail 5-1 simultaneously, finally make four ferrum gripping sleeve 4-1 bringing together, and downhill race rope 9 is applied clamping pressure radially, thus producing enough frictional resistance, slow down the outer layer sleeve 1 relative gliding speed along downhill race rope 9, it might even be possible to directly make outer layer sleeve 1 and downhill race rope 9 be in the locking state of geo-stationary. when the one-level disc 2-1-1 of lower platen 2-1 contacts again with retainer ring 3 upper surface, top pressure circular arc termination 7-1 reaches rotational limitation position, thus lax handle 7 is formed rotary spacing protection.
