Abstract
The utility model discloses a novel multi -functional jack, including main part, stay cord, base and backup pad, base and backup pad all are the cuboid form, the stay cord both ends are stiff end and expansion end respectively, the main part lower extreme is located the upper surface at base middle part, lower surface department in the middle part of the backup pad is then connected to the main part upper end, in the backup pad, all be connected with one through the pulley base along its self length direction's both ends and go up the fixed pulley, on the base, be connected with a lower fixed pulley through the pulley base along its self length direction's one end, one end then links to each other with the stiff end of stay cord in addition, the expansion end of stay cord is fixed pulley and a lower fixed pulley on two in proper order then, on the base, respectively be fixed with a perpendicular ascending elastic component along the upper surface at its self length direction's both ends on to link to each other with the backup pad through the elastic component. The utility model discloses reseing fast of jack can be realized, its function has been increased again.
Description
Technical field
The utility model relates to technical field of jacks, specifically a kind of Multifunction jack.
Background technology
Jack after a certain period of use time, there are some wearing and tearing in capital, the situation such as friction force increasing, performance reduction in return stroke, thus there will be after by supported object top to specified altitude assignment, when jack needs to reset, reset slowly, even occur situation about temporarily not resetting.At this moment, general processing mode, be all that staff gives it with hand in jack upper end and applies some external force, reset work is just triggered, is opened.But sometimes, because working space is very narrow and small, staff is difficult to manual handle.
In addition, present jack generally can only be placed in below weight, and risen by weight or landing certain altitude, function is comparatively single.
Utility model content
The technical problems to be solved in the utility model is: for overcoming the problems referred to above, provides a kind of Multifunction jack.
The utility model solves the technical scheme that its technical matters adopts: a kind of Multifunction jack, comprises main body, stay cord, base and stay bearing plate, and described base and stay bearing plate are all in rectangular-shaped, and described stay cord two ends are respectively fixed end and movable end; Described main body lower end is positioned on the upper surface in the middle part of base, and described main body upper end is then connected to stay bearing plate middle lower surface place; On described stay bearing plate, the two ends along himself length direction are all connected with a upper fixed pulley by pulley base; On described base, the one end along himself length direction is connected with a lower fixed pulley by pulley base, and one end is then connected with the fixed end of stay cord in addition; The movable end of described stay cord, then successively after two upper fixed pulleys and a lower fixed pulley, is connected with thing to be moved; On described base, be respectively fixed with an elastic component vertically upward along on the upper surface at the two ends of himself length direction, and be connected with stay bearing plate by elastic component.
Preferably, the lower fixed pulley on described base to be positioned on described stay bearing plate on one of them immediately below fixed pulley.
The beneficial effects of the utility model are:
1, those can be made to have wearing and tearing, in reseting procedure there is the jack of reset gridlock in meeting because of problems such as friction force is large, performance reductions, when resetting, and Rapid reset, and do not need manually to apply external force to it;
2, jack disclosed in the utility model is except rising the weight of side placed on it or land except certain altitude, can also translation fast and efficiently or lifting not weight above it, no longer with manually pulling, being elevated these weights, greatly reduce working strength and work capacity.
Accompanying drawing explanation
Fig. 1 is the utility model integral structure schematic diagram;
Fig. 2 is the working state schematic representation of the utility model when being elevated some weights not above jack;
Working state schematic representation when Fig. 3 is some weights not above jack of the utility model translation.
Detailed description of the invention
Be described in further detail the utility model by reference to the accompanying drawings now, these accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, Figure 2 and Figure 3, a kind of Multifunction jack, comprises main body 5, stay cord 7, base 6 and stay bearing plate 1, and described base 6 and stay bearing plate 1 are all in rectangular-shaped, and described stay cord 7 two ends are respectively fixed end 71 and movable end 72;
Described main body 5 lower end is positioned on the upper surface in the middle part of base 6, and described main body 5 upper end is then connected to stay bearing plate 1 middle lower surface place;
On described stay bearing plate 1, the two ends along himself length direction are all connected with a upper fixed pulley 32 by pulley base 4;
On described base 6, the one end along himself length direction is connected with a lower fixed pulley 31 by pulley base 4, and one end is then connected with the fixed end 71 of stay cord 7 in addition;
The movable end 72 of described stay cord 7, successively after two upper fixed pulleys 32 and a lower fixed pulley 31, is connected with thing 8 to be moved;
On described base 6, along the upper surface at the two ends of himself length direction being respectively fixed with an elastic component 2 vertically upward, and be connected with stay bearing plate 1 by elastic component 2.
Preferably, the lower fixed pulley 31 on described base 6 to be positioned on described stay bearing plate 1 on one of them immediately below fixed pulley 32.
In sum, the utility model can make those have wearing and tearing, and in reseting procedure, the jack of reset gridlock appears in meeting because of problems such as friction force is large, performance reductions, when resetting, and Rapid reset, and do not need manually to apply external force to it.Simultaneously except the weight of side placed on it to be risen or except landing certain altitude, can also translation fast and efficiently or lifting not thing to be moved 8 above it, no longer with manually pulling, being elevated these weights, greatly reduce working strength and work capacity.
