Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail
As depicted in figs. 1 and 2, a kind of rope drop device, its profile is rectangle frame, regulates knot including body 1 and rope
Structure, it is internal that described rope adjustment structure is located at body 1, including U-shaped levered adjustment mechanism 3, speed regulation button 2, rope
Rope brake block 4 and rope braking roll 5；Body 1 is made up of two hinges, has U-type groove 1a1, in hinge 1a in groove
By the two of both sides strong points, U-shaped levered adjustment mechanism 3 is installed；The most described U-shaped levered adjustment mechanism 3
A speed regulation button 2 it is provided with on transverse axis center；One end of speed regulation button 2 described as shown in Figure 4 and rope
Rope brake block 4 contacts and is embedded in the adjusting grooves 1b1 in right hinge 1b, space and rope brake block 4 and speed regulation
The size assortment of button 2 is suitable, should not too tight also should not be the most loose；Installed by both sides bearing on the relevant position in portion in the body
There is the rope braking roll 5 that surface processes through annular knurl, and two joining distal ends of two ends and described U-shaped levered adjustment mechanism 3
Touch.
Further, the upper end interposition of described body 1 is equipped with two rope through holes that match, and weighs under hinge 1b
One end of beam has a same rope through hole, and the rope through hole center of circle is on one end of adjusting grooves 1b1.
Further, the bottom surface of described speed regulation button 2 there is a draw-in groove 2b, and be stuck in U-shaped adjusting rod 3a
On, both optimal fit systems are interference fit, the center line of another side has a support spring 7, presses to speed regulation all the time
Button 2 provides active force upwards；Having a keyway 2a in speed regulation button 2 front and back sides center, its length range is 4～8mm,
The centre of groove passes rivet, plays the effect of locating speed regulation button 2 upper and lower displacement.
Further, described U-shaped levered adjustment mechanism 3 is by U-shaped adjusting rod 3a, deceleration bar 3b and arm bar 3c,
The ratio of good power arm and resistance arm is 3:1；The two ends of two arm bar 3c are respectively by rivet and U-shaped adjusting rod 3a with subtract
Speed bar 3b carries out rotatability connection；It is one the most right that the side that the other end of described deceleration bar 3b contacts with rope braking roll 5 has
There is roundlet column type decorative pattern in title property chamfering and chamfering inclined-plane, add frictional force when rubbing in contrast；Described arm bar 3c
By on two cylinder boss that centre bore is fixed in U-type groove 1a1 of hinge 1a and can rotate around the boss center of circle, the anglec of rotation is
Good is 60 degree；The two ends, bottom surface of described U-shaped adjusting rod 3a have a support spring 8 respectively, to U-shaped adjusting rod 3a provide to
On active force make its kinestate that keeps up, press speed regulation button 2 time make it can automatically restore to original position.
Further, it is outside that the end face that described rope brake block 4 contacts with speed regulation button 2 is begun with one by center line
The inclined-plane 4b extended, stretches out 5～10mm, and the place that the other end coordinates with the rope through hole on hinge 1b is provided with depression
Semicircle cambered surface 4a, and the radius of semicircle cambered surface 4a is identical with the radius of rope through hole.
Rope is had only to through the rope through hole on this device top and to be wound around around rope braking roll 5 when using this device
One circle (the most produced mill difference power of the number of turns of winding is the biggest) then and pulls out through the rope through hole of bottom；When in rock-climbing
As long as decline or one hold speed regulation button 2 and down press and will produce two active forces during high-rise life saving simultaneously, one promotes
Rope brake block 4 toward rope while motion force rope therewith produce friction thus be slowed or shut off its glide；Another power is then
It is to act on U-shaped levered adjustment mechanism 3, makes the U-shaped adjusting rod 3a of U-shaped levered adjustment mechanism 3 glide and pass through lever
Act on minimum power make deceleration bar 3b inclined-plane directly with rope braking roll 5 the interior intracavity extruding that body 1 is narrow and small produce rub from
And make rope braking roll 5 stop operating and force rope with rope braking roll 5 not relative to sliding or reduce the speed relatively slided
Realize reducing the speed glided.If getting hold of the speed changing downslide that size firmly just can be random, allow user easily
Land from high-altitude gliding safety.
More than be shown and described the ultimate principle of the present invention, principal character and the present invention excellent a little.The technology of the industry
Personnel are not it should be appreciated that the present invention is limited by examples detailed above, and the simply present invention's of the description in examples detailed above and description is former
Reason, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes and improvements
Both fall within scope of the claimed invention.
