Description
Technical field
The utility model relates to the parts of lifting desk surface, relates in particular to a kind of lifting body of lifting desk surface.
Background technology
Existing desk height is all constant, and it highly can't change.The clerk is in for a long time on the desk desktop of sustained height and handles official business, and very easily produces the occupational disease of waist, back, neck or shank.More existing desk with elevating function has well solved this problem, but existing lifting desk surface is all generally to adopt the scissor-type lifting.In the starting stage of lifting, because the arm of force of support bar is longer, so the power that needs is also larger, make lifting desk surface starting difficulty.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of novel and reasonable structure, and degree of being connected firmly is high, the labour-saving lifting body of starting to walk.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of lifting body of lifting desk surface comprises upper bed-plate, lower bottom base and bracing or strutting arrangement, upper bed-plate is connected with lower bottom base by bracing or strutting arrangement, be provided with sliding tray in upper bed-plate inside, the sliding tray center is provided with screw mandrel, the bracing or strutting arrangement upper end is connected on screw mandrel, and the upper end of bracing or strutting arrangement is connected with screw mandrel by the lifting servomechanism; Described lifting servomechanism comprises the first slide block, the second slide block, the first link rod and the second link rod, and the first slide block and the second slide block are arranged on screw mandrel, and the first slide block and the second slide block slide in sliding tray along screw mandrel; The first slide block is connected with the upper end of bracing or strutting arrangement, and the upper end of the first link rod is connected to the junction of the first slide block and bracing or strutting arrangement, and the lower end of the first link rod and the second link rod are rotationally connected; The upper end of the second link rod is connected with the second slide block.
As preferably, the middle part of the lower end of the first link rod and the second link rod is hinged by bearing pin.
As preferably, bracing or strutting arrangement is made of two support bars, and two support bars middle parts intersect and are rotationally connected.
The utility model adopts above scheme, and the upper end of bracing or strutting arrangement is connected with screw mandrel by the lifting servomechanism.The upper end of the first link rod on the lifting servomechanism is connected to the junction of the first slide block and bracing or strutting arrangement, and the lower end of the first link rod and the second link rod are rotationally connected; The upper end of the second link rod is connected with the second slide block.During starting, the second slide block drives the second link rod by screw mandrel, and the second link rod slowly vertically gets up and drives the upper bed-plate lifting, and bracing or strutting arrangement is auxiliary, until the second slide block contacts with the first slide block, makes starting more laborsaving.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the lifting body of a kind of lifting desk surface of the utility model is described in further detail.
The lifting body of a kind of lifting desk surface as shown in Figure 1 comprises upper bed-plate 1, lower bottom base 2 and bracing or strutting arrangement 3.Bracing or strutting arrangement 3 is made of two support bars, and two support bars middle parts intersects and is rotationally connected, and traditional scissor-type lifting structure makes lifting desk surface hoist higher stability, roomy hoistable platform and higher bearing capacity.Upper bed-plate 1 is connected with lower bottom base 2 by bracing or strutting arrangement 3.Be provided with sliding tray 11 in upper bed-plate 1 inside, sliding tray 11 centers are provided with screw mandrel 12, and bracing or strutting arrangement 3 upper ends are connected on screw mandrel 12, and the upper end of bracing or strutting arrangement 3 is connected with screw mandrel 12 by lifting servomechanism 4.
Lifting servomechanism 4 comprises the first slide block 41, the second slide block 42, the first link rod 43 and the second link rod 44.The first slide block 41 and the second slide block 42 are arranged on screw mandrel 12, and the second slide block 42 is arranged on the screw mandrel 12 away from bracing or strutting arrangement 3 of the first slide block 41, the first slide block 41 and the second slide block 42 along screw mandrel 12 in the interior slip of sliding tray 11.The first slide block 41 is connected with the upper end of bracing or strutting arrangement 3, and the upper end of the first link rod 43 is connected to the junction of the first slide block 41 and bracing or strutting arrangement 3.The lower end of the first link rod 43 and the second link rod 44 are rotationally connected, specifically the middle part of the lower end of the first link rod 43 and the second link rod 44 is hinged by bearing pin, due to the first link rod to drive the second link rod integrated moving, it is best that the lower end of the first link rod 43 and the middle part of the second link rod 44 are connected effect, the upper end of the second link rod 44 is connected with the second slide block 42, and the lower end of the second link rod contacts with lower bottom base and breaks away from lower bottom base with the lifting of bracing or strutting arrangement.
When lifting desk surface is started to walk, the second slide block 42 drives the second link rod 44 by screw mandrel 12, the second link rod 44 slowly vertically gets up and drives upper bed-plate 1 lifting, bracing or strutting arrangement 3 is auxiliary, until the first slide block 41 contacts with the second slide block 42, and the second slide block 42 is socketed in the endoporus of the first slide block 41, and is more stable when making ground zero like this.After starting steadily, the lower end of the second link rod 44 and lower bottom base 2 break away from, and bracing or strutting arrangement 3 is propped up upper bed-plate 1.
During due to ground zero, distance between Up/down base very near, the second link rod 44 is to bracing or strutting arrangement 3 one side shifting the time, on the one hand: because bracing or strutting arrangement 3 struts upper bed-plate 1 and lower bottom base 2, the second link rod 44 from the original state of droping to the ground slowly vertically; On the other hand: the second link rod 44 that vertically gets up makes starting more laborsaving also promoted upper bed-plate 1 and lower bottom base 2 to strut to bracing or strutting arrangement 3 one side shiftings.
