Description
Technical field
The invention belongs to a dead lift field of mechanical technique.
Background technology
Existing furniture carrier all well is not applicable to floor type furniture.These furniture complicated operations, required labour power is big.
Like disclosed carrier in the Chinese patent 200720020618, it utilizes three baffle plates of base, and three baffle plates have a common drift angle, and the bottom of one of them baffle plate is provided with strut bar, and strut bar is scalable, and the other end of strut bar is connected with roller.Though this carrier is simple in structure, can solve the carrying problem of some large-scale furniture, owing to there is base, it can not carry floor type furniture, and when promoting, also requires great effort.
Summary of the invention
The object of the invention just provides a kind of portable furniture Handling device, and it is simple in structure, small and exquisite, and the parts accuracy requirement is low, and is with low cost; Easy and simple to handle during use, be applicable to the people of all age group to comprise old man and child.
The present invention solves its technical matters, and the technical scheme that is adopted is: a kind of portable furniture Handling device, and the support two ends are provided with cardan wheel, the middle part center link that is threaded; Center link passes the through hole of shell lower cover bottom, and insert in the shrinkage pool of rotating shaft the upper end, and the shell lower cover is connected by spring with the protruding dish at center link middle part; The shrinkage pool coupling of the top of rotating shaft and depression bar lower end, the helical teeth of rotating shaft bottom and the helical teeth of depression bar are in contact with one another the formation ratchet device, slide block pin joint depression bar; Serrated slot is fixed on enclosure, has slide block to cooperate in the groove, and a deep trouth is arranged at the depression bar top; Its inside is connected with lever hinge, and a sleeve is arranged at the pedal top, and lever inserts wherein; Connecting rod one end is connected with lever hinge, and the other end is connected with shell also hinge, cross bar that the shell middle part is outstanding and the welding of the cross bar in the middle of the sucker.
The overall work situation of this furniture carrier is following: furniture is connected with carrier through sucker, through to the trampling of pedal, makes lever produce an enough big strength furniture is lifted.Easily move furniture behind any position via cardan wheel, thereby pushes pedals is placed on the ground furniture once more, accomplishes the action of furniture carrying.
Realization is locked after with the furniture lifting; The concrete principle of work of structure of putting down This move once more after the pushes pedals is: through lever to the downward application of force of depression bar; Depression bar moves downward and promotes the below rotating shaft and moves down relatively that (in integral structure, the sleeve and outer wall concrete mutually at guide groove place are fulcrum so actual motion is a lever with the depression bar top; Outer wall, the related furniture at sleeve place are together levered up), furniture is lifted under the support of cardan wheel in this process.Meanwhile; Because depression bar is that angle contact with rotating shaft, rotating shaft is moving downward the effect anti-clockwise rotation when guide groove is terminal, understood because of side force in next serration groove, like this after having removed trampling of applying; Rotating shaft will rest in the serrated slot, accomplish locked purpose.
The process that furniture puts down once more is similar with the process of lifting; Pushes pedals once more; Depression bar promotes rotating shaft and moves downward a very little segment distance; When the vertical wall of serrated slot terminal, rotating shaft can so just have been accomplished the operation that furniture puts down because the effect anti-clockwise rotation of angle side force is finally got back in the guide groove once more equally.
Below in conjunction with accompanying drawing and the specific embodiment the present invention is done and to further describe.
Description of drawings
Accompanying drawing 1 is integral structure scheme drawing of the present invention.
Accompanying drawing 2 is inner structure enlarged diagram of the present invention.
Accompanying drawing 3 is the cooperation enlarged diagram of depression bar of the present invention and rotating shaft.
The specific embodiment
Fig. 1-3 illustrates, and a kind of specific embodiment of the present invention is: a kind of portable furniture Handling device is characterized in that: support 6 two ends are provided with cardan wheel 7; The middle part center link 13 that is threaded, center link 13 passes the through hole of shell lower cover 5 bottoms, and insert in the shrinkage pool of rotating shaft 12 upper end; Shell lower cover 5 is connected by spring 14 with the protruding dish at center link 13 middle parts, the shrinkage pool coupling of the top of rotating shaft 12 and depression bar 3 lower ends, and the helical teeth of rotating shaft 12 bottoms and the helical teeth of depression bar 3 are in contact with one another the formation ratchet device; Slide block 11 pin joint depression bars 3, serrated slot is fixed on shell 4 inside, has slide block 11 to cooperate in the groove; One deep trouth is arranged at depression bar 3 tops, and its inside is connected with lever 2 hinges, and a sleeve is arranged at pedal 1 top; Lever 2 inserts wherein; Connecting rod 9 one ends are connected with lever 2 hinges, and the other end is connected with shell 4 also hinge, the cross bar welding in the middle of cross bar that shell 4 middle parts are outstanding and the sucker 8.
Furniture is connected with carrier through sucker 8, through to the trampling of pedal 1, makes lever 2 produce an enough big strength furniture is lifted.Easily move furniture behind any position via cardan wheel 7, thereby pushes pedals 1 is placed on the ground furniture once more, accomplishes the action of furniture carrying.
Realization is locked after with the furniture lifting; The concrete principle of work of structure of putting down This move once more after the pushes pedals 1 is: through the downward application of force of 2 pairs of depression bars of lever 3; Depression bar 3 moves downward and promotes below rotating shaft 12 and moves down relatively that (in integral structure, the sleeve and outer wall concrete mutually at guide groove place are fulcrum so actual motion is a lever 2 with depression bar 3 tops; Outer wall, the related furniture at sleeve place are together levered up), furniture is lifted under the support of cardan wheel 7 in this process.Meanwhile; Because depression bar 3 is that angle contacts with rotating shaft 12; Rotating shaft 12 move downward to guide groove terminal in can because the effect anti-clockwise rotation of side force in next serration groove; After having removed trampling of applying, rotating shaft will rest in the serrated slot like this, accomplish locked purpose.
The process that furniture puts down once more is similar with the process of lifting; Pushes pedals 1 once more; Depression bar 3 promotes rotating shaft and moves downward a very little segment distance; When the vertical wall of serrated slot terminal, rotating shaft 12 can so just have been accomplished the operation that furniture puts down because the effect anti-clockwise rotation of angle side force is finally got back in the guide groove once more equally.
Insert in the depression bar 3 on rotating shaft 12 tops, and two end teeth cooperatively interact and can slide.
