Description

A kind of pedestal

Technical field

The utility model relates to a kind of pedestal of not only can stable support but also can easily move.

Background technique

Usually the pedestal of objects such as furniture, electrical equipment, equipment all is that four fixed supports directly are set, to reach the effect of safe support object, but the bigger object of object that frequently moves for needs or volume, quality is in the process that moves, need implement by external force, time and effort consuming brings more inconvenience.

In addition, have the roller dolly, move more conveniently, but can not stablize stop having on the ground of minor grade, bring many unsafe factors.

The model utility content

The technical problems to be solved in the utility model provides a kind of pedestal of not only can stable support but also can easily move.

For solving the problems of the technologies described above, the utility model adopts following technological scheme:

A kind of pedestal, comprise substrate, described substrate bottom surface is provided with fixed support, expanding pulley device and expanding pulley control gear, this expanding pulley device comprises the crossbeam that is fixed on the described substrate bottom surface and is provided with the stationary axle of torque spring and is hinged on stationary axle and the bottom surface is fixed with the roller fixed plate of roller, described crossbeam and roller fixed plate are distributed in the both sides of stationary axle, and the two ends of torque spring are stuck on crossbeam and the roller fixed plate; Described expanding pulley control gear is the lifting handle that is provided with on the substrate top of the described roller fixed plate of correspondence.

The height h that described expanding pulley device stretches _Stretch, the height h that shrinks _ContractHeight h with described fixed support _Gu _{The fixed support}Between the pass be h _Contract≤ h _{Fixed support}＜h _Stretch

Because the situation that roller can not normally use appears in roller fixed plate paratonia, and the expanding pulley device is provided with the baffle plate of roller fixed plate, this baffle plate is across the bottom surface of crossbeam, stationary axle and roller fixed plate, and an end is fixedly installed on the crossbeam in order to prevent.The maximum position that described roller fixed plate stretches is the horizontal position that is parallel to described baffle plate, so that roller reaches vertical proper motion state.

Described crossbeam is that a section is the right angle ellbeam, and this right angle ellbeam and described roller fixed plate folding form alive is arranged on the stationary axle.

Described lifting handle is that thread screw is connected with substrate, and described substrate is provided with the tapped hole of coupling.

Described substrate is arranged with two expanding pulley devices.

Be arranged with two rollers on the described roller fixed plate.

The utlity model has following advantage:

1) the utility model is provided with fixed support and expanding pulley device on substrate, can realize fixed support and two kinds of user modes that arbitrarily move according to actual needs, the expanding pulley device stretches objects such as being used for mobile furniture, for mobile frequent seat series products, can continue to keep removable state; Expanding pulley is regained, and roller stashes, and is simple in structure, easy to use by the safe support of fixed support, effectively solves carrying inconvenience or problem that can not safe stop.

2) the utility model applies active force by lifting handle and torque spring pair roller fixed plate, controls the flexible of roller with this, and can continue to keep flexible state, and easy to use, action effect is good.

Embodiment

Shown in Fig. 1,2,3,4, a kind of pedestal described in the utility model, comprise substrate 1, described substrate 1 bottom surface is provided with four fixed supports 2, is provided with two expanding pulley devices 3 and corresponding expanding pulley control gear----lifting handle 4 in the bilateral symmetry of substrate.

Shown in Fig. 6 and 9, this expanding pulley device comprises the right angle ellbeam that is fixed on described substrate 1 bottom surface 5 and is provided with the stationary axle 7 of torque spring 6 and is hinged on stationary axle 7 and the bottom surface is fixed with the roller fixed plate 9 of two rollers 8, this right angle ellbeam 5 is arranged on the stationary axle 7 with described roller fixed plate 9 folding forms alive, and the two ends of torque spring 6 are stuck on right angle ellbeam 5 and the roller fixed plate 9; The expanding pulley device also is provided with the baffle plate 10 of roller fixed plate 9, and this baffle plate 10 is across the bottom surface of right angle ellbeam 5, stationary axle 7 and roller fixed plate 9, and an end is fixedly installed on the right angle ellbeam 5.As described in Fig. 1,9,10, the maximum position that described roller fixed plate 9 stretches is the horizontal position that is parallel to described baffle plate 10, so that roller 8 reaches vertical proper motion state.

Shown in Fig. 1,3, described expanding pulley control gear is the lifting handle 4 that connects setting at the substrate 1 top thread screw of the described roller fixed plate 9 of correspondence, and described substrate 1 is provided with the tapped hole 11 of coupling.

Described substrate 1 is during by the safe support of fixed support 2, during contraction state that described roller fixed plate 9 and roller 8 are in, shown in Fig. 5,6,7.

When if the pedestal needs are mobile, lifting handle 4 is down rotated, lifting handle 4 sees through substrate 1 and acts on the roller fixed plate 9, roller fixed plate 9 is at the active force lower compression torque spring 6 of lifting handle 4, simultaneously, with stationary axle 7 is the direction rotation of axial baffle 10, reduce, and drive roller 8 and down move, until reaching as Fig. 1,2,3,8,9, state shown in 10, roller fixed plate 9 is parallel with baffle plate 10, the roller full extension, at this moment, can be according to furniture, equipment or weight are placed on the substrate 1 and carry, and be time saving and energy saving, for the frequent object that moves, can keep this kind state to move.

When object that needs move such as equipment or dolly move finish after, lifting handle 4 is up rotated, roller fixed plate 9 is under the effect of the restoring force of torque spring 6, with stationary axle 7 serves as axially to rotate, rise away from the direction of roller baffle plate 10, drives roller simultaneously and upwards shrinks, and is returned to the state shown in Fig. 5,6,7, roller stashes, come safe support by fixed support, and can dwindle the volume of pedestal, save the space.

Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all mode of executions.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
