As a further arrangement of the present invention, the fixing block is disposed near the end of the respective guide rail.

Among the above-mentioned technical scheme, the fixed block is close to the guide way of guide rail tip as far as possible, because the slide needs to follow the guide rail removal, has certain displacement, so two fixed blocks will keep away from each other as far as possible, just so can ensure the displacement of slide, simple structure, it is reasonable to distribute.

As the utility model discloses a further setting, a cavity has on the fixed block, is provided with a breach on the inner wall of this cavity, the width and the cable wire adaptation of breach supply the cable wire to pass, and the width of cavity is greater than the width of breach.

Among the above-mentioned technical scheme, the cable wire can pass through the joint with being connected of fixed block, and the tip of cable wire has an enlarged body, should enlarge the body and arrange the cavity in, because of the width of breach is less than the width of cavity, so enlarge the body and constitute the joint with the breach, avoid cable wire and fixed block to throw off, handle axle dorsad in the opening of cavity, another towards handle axle, the connection is stable.

The present invention will be further described with reference to the accompanying drawings.

Detailed Description

The utility model discloses a concrete embodiment is shown in fig. 1-2, a sheave glass-frame riser ware, including guide rail 1, slide setting slide 2 on guide rail 1, connect two cable wires 21 on slide 2 and through handle axle 3 that cable wire 21 drive slide 2 removed, the one end winding of cable wire 21 is on handle axle 3's line wheel 31, and the guide way 11 that the other end was walked around guide rail 1 both ends is connected with slide 2, be provided with pulley 22 on slide 2, the tip of cable wire 21 is walked around pulley 22 after-fixing on the fixed block 12 of setting on guide rail 1. Through the input manpower mechanical input power on handle shaft 3, give the mechanism certain power, the mechanism moves according to original mechanical transmission mode, pulley 22 on slide 2 just is movable pulley 22 group this moment, play the effect of change power's size, the input of effectual reduction manpower, under the same load condition, compare the required input power of original mechanism operation, movable pulley 22 group that new construction adopted can be under the same load condition, use littleer input power, reach the predicted effect, increase of service life.

At least two pulleys 22 are provided for winding the two wires 21. The preferable two pulleys 22 correspond to the two steel cables 21 respectively, and when the steel cable 21 drives the sliding plate 2 to move, the pulleys 22 do rolling motion, so that the input force is reduced, and the lifting effect is better.

The pulley 22 is positioned between the sliding plate 2 and the guide rail 1 and fixed on the sliding plate 2 through a rivet 23, and the pulley 22 and the rivet 23 are arranged in a rotating mode. The rivet 23 is fixed on the sliding plate 2, the pulley 22 is sleeved on the rivet 23 and is arranged in a rotating mode, the pulley 22 and the fixed block 12 are basically located on the same plane, the maximum transmission efficiency of force is guaranteed, connection is convenient, and the structure is simple.

An annular groove 221 into which the wire rope 21 is fitted is formed on the outer peripheral surface of the pulley 22. The annular groove 221 is arranged to avoid the separation of the steel cable 21 and the pulley 22 and has a guiding function, and the groove bottom of the annular groove 221 is a concave cambered surface, so that the structure is simple and the processing is convenient.

The fixing blocks 12 are disposed near the ends of the respective guide rails 1. The fixed block 12 is close to the guide way 11 of the end part of the guide rail 1 as far as possible, and because the sliding plate 2 needs to move along the guide rail 1 and has a certain moving distance, the two fixed blocks 12 are far away from each other as far as possible, so that the moving distance of the sliding plate 2 can be ensured, the structure is simple, and the distribution is reasonable.

The fixing block 12 has a cavity 121, and a notch 1211 is formed on an inner wall of the cavity 121, wherein the width of the notch 1211 is adapted to the cable 21 and allows the cable 21 to pass through, and the width of the cavity 121 is greater than the width of the notch 1211. The connection between the cable 21 and the fixing block 12 can be achieved by clamping, the end of the cable 21 has an enlarged body, the enlarged body is placed in the cavity 121, and the width of the gap 1211 is smaller than that of the cavity 121, so that the enlarged body and the gap 1211 form clamping to prevent the cable 21 from being separated from the fixing block 12, one opening of the cavity 121 faces away from the handle shaft 3, and the other opening faces towards the handle shaft 3, and the connection is stable.

The utility model discloses do not confine the above-mentioned embodiment to, the general technical personnel in this field can adopt other multiple embodiments to implement according to the utility model discloses a, perhaps all adopt the utility model discloses a design structure and thinking do simple change or change, all fall into the utility model discloses a protection scope.
