Abstract

The utility model relates to a winder for lifting objects. The utility model is characterized in that the winder comprises a base, a main shaft fixed on the base, a brake drum, a brake torsion spring sheathed on the brake drum as well as a shift fork and a reel coaxially sheathed on the main shaft, wherein, the shifting folk is provided with a handle end head connected with a crank handle; the reel is provided with a built-in pigtail clip composed of a bushing matched with a wedge; the transmission connection between the crank handle and the shifting fork adopts a key joint mode or a pin connection mode. The utility model has the advantages of beautiful appearance of rope-winding, reasonable stress of units, convenient assembly and disassembly, uneasily damaged units, etc.

Description

The rope coiler

The utility model relates to a kind of rope coiler that drives object up-down.

Chinese patent ZL99235515.X discloses a kind of rope coiler, contain base, main shaft, reel, main shaft is fixed on the base, be shaped on the brake wheel that is fixed on the base on the main shaft, be set with Brake torsion spring on the brake wheel, be set with shift fork on main shaft, the Brake torsion spring, shift fork is provided with and holds the radially notch of grab of Brake torsion spring, be set with reel on the shift fork, be shaped on the reel inwall and the Brake torsion spring key that cooperates of grab radially, handle is installed on the shift fork.But the reel rope fixed end of its rope coiler is exposed, influences the attractive in appearance and result of use that rope twines, simultaneously, the unreasonable structure that is in transmission connection of its crank termination and shift fork, parts are fragile.

Main purpose of the present utility model is at above-mentioned weak point, provides a kind of rope winding effect good rope coiler.

Secondary objective of the present utility model is at above-mentioned weak point, and a kind of rational in infrastructure, non-damageable rope coiler of parts is provided.

The realization of the utility model main purpose, be such: containing base, main shaft, on the rope coiler of reel, main shaft is fixed on the base, be shaped on the brake wheel that is fixed on the base on the main shaft, be set with Brake torsion spring on the brake wheel, main shaft, be set with shift fork on the Brake torsion spring, shift fork is provided with and holds the radially notch of grab of Brake torsion spring, be set with reel on the shift fork, be set with on the shift fork and connect the crank termination that wind is used, the crank termination, shift fork constitutes transmission device, Brake torsion spring, the hook horse, the sleeve of brake wheel and reel constitutes self-locking device, the wedge that described reel is provided with lining and mates with lining, lining, wedge constitutes built-in bulldog grip.

The implementation of the utility model secondary objective is such, and the mode of being in transmission connection between crank termination and the shift fork adopts key joint, and the inboard of the termination of shift fork and crank termination can be that the section spline that matches each other connects.

Another implementation of the utility model secondary objective is such, and the crank termination is that pin is connected with the mode of being in transmission connection between the shift fork, and pin can be horizontally disposed with along the shift fork rotation direction, is provided with one at the position of the corresponding pin of main shaft and holds the circular groove that pin rotates; Pin also can radially be provided with one or many along crank termination and shift fork.

Certainly, above-mentioned two kinds of implementations of the utility model secondary objective also can be used better effects if simultaneously.

The utility model has following advantage:

1, the rope fixed end is built-in, does not influence rope and twines, and is attractive in appearance again;

2, adopt key joint or pin to connect, type of drive is reliable, and the parts force structure is reasonable, and is not fragile, and crank termination and shift fork adopt the section spline to connect, and peace is torn open conveniently.

Following embodiment is further described the utility model in conjunction with the accompanying drawings.

Fig. 1 is the rope coiler structural representation of the exposed end reel of the disclosed employing of ZL99235515.X;

Fig. 2 is the main TV structure figure of the utility model embodiment;

Fig. 3 be Fig. 2 embodiment along B-B to cutaway view;

Fig. 4 be Fig. 2 embodiment along C-C to section-drawing;

Fig. 5 is that Fig. 2 embodiment cuts open a view along A in the middle of the reel of being seen;

Fig. 6 be Fig. 2 embodiment along D-D to section-drawing;

Fig. 7 be Fig. 2 embodiment along E-E to section-drawing;

With reference to Fig. 2～Fig. 7, present embodiment is to contain base 10, main shaft 1, the rope coiler of reel 2, main shaft is fixed on the base, be shaped on the brake wheel 8 that is fixed on the base on the main shaft, be set with Brake torsion spring 6 on the brake wheel, main shaft, be set with shift fork 4 on the Brake torsion spring, be set with reel on the shift fork, be set with on the shift fork and connect the crank termination 3 that wind is used, by crank termination 3, shift fork 4 constitutes transmission device, by Brake torsion spring 6, hook horse 7, the sleeve 213 of brake wheel 8 and reel 2 constitutes self-locking device, reel is provided with built-in bulldog grip 21, bulldog grip reaches the wedge 212 that mates with lining by lining 211 and constitutes, the mode of being in transmission connection between inboard, crank termination and shift fork are not held is a

section spline

31,41 connect, behind crank termination and shift fork suit, be horizontally disposed with a pin 5 along the shift fork rotation direction, the position of main shaft 1 corresponding pin is provided with one and holds the circular groove 12 that pin rotates.

Using method of the present utility model, the bulldog grip lining that rope 9 is through reel is loaded onto wedge, shakes the crank termination, and by the

section spline

31,41 of crank termination and sell 5 transmissions and drive shift fork and rotate, reel twines rope.

As the another kind of embodiment of present embodiment, the pin 5 that is provided with between crank termination and the shift fork can be disposed radially.
