Abstract
The utility model discloses a kind of laborsaving drag-line, comprise housing and slide up and down the slide block be connected in housing, described slide block is provided with a guide roller, and described guide roller is arranged in the middle part of slide block; Initiatively cable core one end and inner walls upper end are fixed, and the other end stretches out from housing upper end after walking around guide roller 180 degree; Described slider bottom is connected with passive cable core, and described passive cable core one end and slider bottom are fixed, and the other end stretches out housing lower end.By the brake holding load using device described in the utility model can save about half, need the braking distance doubled simultaneously, braking can be made so more laborsaving, be more prone to operation.
Description
Technical field
The utility model relates to a kind of laborsaving drag-line.
Background technology
As everyone knows, the interaction relation of each rod member, usually need to rely on some to realize for the drag-line drawn, what market generally used generally includes cable core for the drag-line drawn and is socketed in the noose of cable core outside, the die casting of cable core outer end has the dop coordinated with clamping part, but existing drag-line is single line drag-line, pulls the strength of end to be the strength of dog point, like this when needing the brake holding load strengthened, the person of pulling can seem and comparatively require great effort.Prior art is badly in need of the one comparatively laborsaving drag-line in labour-saving.
Utility model content
The purpose of this utility model is to overcome the defect existed in prior art, provides the one comparatively laborsaving drag-line in labour-saving.
For achieving the above object, the technical solution of the utility model there is provided a kind of laborsaving drag-line, and comprise housing and slide up and down the slide block be connected in housing, described slide block is provided with a guide roller, and described guide roller is arranged in the middle part of slide block; Initiatively cable core one end and inner walls upper end are fixed, and the other end stretches out from housing upper end after walking around guide roller 180 degree; Described slider bottom is connected with passive cable core, and described passive cable core one end and slider bottom are fixed, and the other end stretches out housing lower end.By the brake holding load using device described in the utility model can save about half, need the braking distance doubled simultaneously, braking can be made so more laborsaving, be more prone to operation.
As preferably, described slide block is rectangular block, and described guide roller is arranged on the surface of slide block and wheel face is parallel with shoe surface.Such design is the further optimization to scheme.
As preferably, described slide block corner is provided with rounding off angle.Such design is the further optimization to scheme.
Advantage of the present utility model and beneficial effect are: by the brake holding load using device described in the utility model can save about half, need the braking distance doubled simultaneously, braking can be made so more laborsaving, be more prone to operation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, housing; 2, slide block; 3, guide roller; 4, passive cable core; 5, active cable core.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of laborsaving drag-line, comprise housing 1 and slide up and down the slide block 2 be connected in housing 1, described slide block 2 is provided with a guide roller 3, and described guide roller 3 is arranged in the middle part of slide block 2; Initiatively cable core 5 one end and housing 1 inwall upper end are fixed, and the other end walks around guide roller 3(180) spend after stretch out from housing 1 upper end; Be connected with passive cable core 4 bottom described slide block 2, fix bottom described passive cable core 4 one end and slide block 2, the other end stretches out housing 1 lower end.
Described slide block 2 is rectangular block, and described guide roller 3 is arranged on the surface of slide block 2 and wheel face is parallel with slide block 2 surface.
Described slide block 2 four jiaos is provided with rounding off angle.
In use, pull initiatively cable core 5, because active cable core 5 one end and housing 1 are fixed, when pulling, initiatively cable core 5 can force guide roller 3 to roll, and be with movable slider 2 to run, slide block 2 drives passive cable core 4 to run, and can save the brake holding load of about half like this, need the braking distance doubled simultaneously, braking can be made so more laborsaving, be more prone to operation.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing from the front lower of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
