Description

A kind of thin type rope coiler

The utility model relates to the hand coiler that a kind of object up-down is used, particularly a kind of hand rope coiler with auto-lock function.

Make the object rising or descend very common in daily life with the rope coiler, Chinese patent zL95216808.1 discloses a kind of hand rope coiler of self-locking of screw, though it can overcome ratchet, an inconvenient operation that pawl type hand rope coiler exists and the easy back misoperation face of sending out have uneasy congruent weak point, but because it adopts screw rod and spring platen etc. to constitute self-locking device, there is complex structure, manufacture difficulty is big, shortcomings such as cost height, at the problems referred to above, Chinese patent zL97245843.3 discloses the hand rope coiler of a kind of no screw self-locking, though the hand rope coiler of its texture ratio screw self-locking is simple, easy to manufacture, cost is low, self-lock ability is stronger, more reliable, but because its retarding spring is set directly on the center shaft, make the center shaft diameter bigger, materials are many, the cost height, the machine-shaping complexity, inconvenient, simultaneously because the diameter of center shaft is subjected to certain limitation, can not be sufficiently large, the diameter of retarding spring also is affected, can not do too greatly, cause the very flexible of the control of retarding spring like this, inconvenient, and require the base of supporting center shaft that certain thickness will be arranged, make its volume big, it is many to take up room, install and use inconvenience, simultaneously owing to reel directly drives by stirring tube, thereby not laborsaving, the weight of the object that reel hangs is restricted.

The purpose of this utility model provide a kind of volume little, from lock control is more flexible, convenient, self-locking is more reliable, manipulate labour-saving thin type rope coiler.

The utility model comprises pedestal, bolster, stop mechanism, reel, crank, it is characterized in that pedestal is made up of base plate and housing, wherein has the opening that can pass rope on the housing sidewall; Stop mechanism comprises brake wheel, retarding spring, dragging element, wherein brake wheel is fixed on the bolster, the retarding spring flush fit is nested with on brake wheel, and the two ends bent radial of retarding spring forms gib head, the dragging element front portion is provided with two slide blocks and lays respectively at the outside of retarding spring two gib heads, the afterbody of dragging element is connected with crank, be provided with Transmission between the inboard of retarding spring two gib heads, reel is nested with present intracoelomic cavity rotationally and is connected with stop mechanism by train of reduction gears and Transmission.

The utility model reaches reel by train of reduction gears and stop mechanism structure combining owing to adopt retarding spring to be nested with on brake wheel, the bolster diameter can be significantly reduced, thereby reduce the materials of bolster, save cost, and effectively reduce the supporting power of pedestal, make pedestal can do quite thinly, only need base plate and housing just can, thereby significantly reduce the volume of pedestal, it is occupied little space, and, the retarding spring diameter is increased because brake wheel can be done greatlyyer, thereby both made the retarding spring self-locking more reliable, laborsaving again, make the control of retarding spring more flexible again, convenience and machine-shaping are simpler, convenient.Combine with stop mechanism by train of reduction gears owing to reel simultaneously, reel and train of reduction gears were concentrated in the housing, strengthen the globality of its structure greatly, make its more compact structure, use much cleaner, further reduction of while thickness of the present utility model, reduce its shared space, drum diameter is increased, power by dragging element can greatly be saved, and increase the bearing capacity of reel, and the utility model concept is ingenious, simple in structure, specious, practical.
