Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the structural representation that the utility model is equipped with rope;
Fig. 2 is the structural representation of brake block in the utility model;
Wherein: 1. housing, 2. brake block, 3. pulley, 4. rope.
The specific embodiment
Combine accompanying drawing that the utility model is further described now.The sketch map that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
Shown in Figure 2 like Fig. 1; A kind of simple and easy descending lifeline has housing 1, and housing 1 bottom is equipped with brake block 2; Brake block 2 tops are placed with the pulley 3 that has race; Pulley 3 flexibly connects with housing 1, and the rubbing surface of brake block 2 matches with the cylindrical wheel face of pulley 3, and the side plate bottom that has the first rope hole, the second rope hole or housing 1 both sides that are used to penetrate rope 4 on the base plate of housing 1 bottom has the first rope hole, the second rope hole that is used to penetrate rope 4; The first rope hole, the second rope hole are respectively in the brake block both sides, and the first rope hole, the second rope hole are respectively in brake block 2 both sides.Pulley 3 cylindrical wheel faces are smooth wheel face, and the rubbing surface of brake block 2 is an arcuate friction surface.Rope 4 passes race, the second rope hole of the first rope hole, pulley 3 successively.Housing 1 top is equipped with the safety belt bolt, and safety belt bolt upper sleeve through has safety belt.It is too fast that safety belt can effectively keep people's health to be difficult for landing.
Pulley 3 with the mode that housing 1 flexibly connects is: the front panel of housing 1 and backplate all have the slotted hole corresponding with the centre bore of pulley 3, behind the centre bore of the slotted hole of screw bolt passes front panel, pulley 3, the slotted hole of backplate nut are installed.Pulley 3 flexibly connects with housing 1, makes pulley 3 in housing 1, to rotate flexibly and is difficult for slippage, drops out.
The race of pulley 3 is for clamping the clamping slot of rope, and the concrete structure of race is: the groove face that the race of pulley 3 is relative has groove and the projection that replaces each other, and the groove and the projection of groove face stagger each other relatively.Groove that is provided with on the pulley 3 race groove faces and projection can clamp rope 4, are difficult for slippage, effectively reduce the speed that rope 4 descends.The race of pulley 3 also can be the up big and down small wedge-shaped slot of opening.
The front panel of housing 1 or backplate have the groove that is used to embed pulley sheave, and this groove can be located pulley on the one hand, can reduce the making volume of housing 1 on the other hand, and the cost of manufacture that reduces housing 1.
The left plate or the right plate of housing 1 have arc groove.The left plate of housing 1 or the arc groove of right plate both can have been left the enough activity spaces of rope for, and the easy demoulding when making housing 1 Mold Making.
The utility model is inverted when using and is used, promptly the base plate of housing 1 up, an end of rope 4 is fixed on eminence; Rope 4 other ends pass pulley 3 back by people's hand control, because the compressing of people's gravity, are through rope 4 on the pulley 3 to lower compression pulley 3; And then pulley 3 wheel faces and brake block 2 are fitted tightly; Reduce the rotary speed of pulley 3, thereby reduce the decrease speed of rope 4, groove that is provided with on the pulley 3 race groove faces and projection also can clamp rope 4; Be difficult for slippage, further reduce the speed that rope 4 descends.The utility model only need use a pulley 3, and the cylindrical wheel face of pulley 3 need not be processed into gear shape, can realize slow function of falling.The utility model is simple in structure, making is simple and easy, manufacturing cost is lower, can conveniently get into family and use.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
