Described projection or positioning hole respectively are three, and each projection or positioning hole are spaced apart with respect to the central shaft equal angles of pedestal or protruding member.
Leg device comprises strut and supporting foot, also comprises above-mentioned linkage structure, and supporting foot is installed on the strut lower end.
Described supporting foot comprises matrix, and is some support arms that the center stretches out and forms with this matrix; Described matrix center is provided with passage; Described strut lower end at least is hollow tubular, thereby forms inwall.
The protruding member of described linkage structure is fixed on the described matrix and pedestal is fixed in the strut inwall; Perhaps protruding member is fixed in described strut inwall and pedestal is fixed on the matrix.
Described leg device further comprises a fastening piece, and described fastening piece passes the central passage of supporting foot matrix and linkage structure pedestal, and supporting foot is fastened on the strut.
The protruding member of described linkage structure and described matrix are fixed on the matrix top by the moulding of metal integrally casting, and pedestal is welded in the strut inwall; Perhaps protruding member is welded in described strut inwall and pedestal and matrix are fixed on matrix top by the moulding of metal integrally casting; Between described fastening piece and the central passage with thread engagement.
Described support arm end is provided with caster.
The beneficial effects of the utility model are as follows: leg device structure of the present utility model is simpler, and cost is lower.Thereby the utility model utilizes the projection of linkage structure to interfix to cooperate with positioning hole supporting foot is installed on the strut lower end, therefore can not produce relative movement between connected supporting foot and the strut, even supported tables are moved, and supporting foot is when meeting other object, can not cause that also supporting foot departs from respect to strut and damages this bindiny mechanism.
In addition, can multiple angles install between supporting foot and the strut, the user can carry out free adjusting as required.
And leg device of the present utility model also comprises a fastening piece, further supporting foot is fixed on the strut, and is fixing more firm, and the dismounting aspect.

Embodiment
Please be simultaneously with reference to shown in Fig. 1-4, leg device 10 of the present utility model is a kind of supporting structures as family property, as being used as support table, desk, dinner table, writing board, report platform etc.This leg device 10 comprises strut 11, supporting foot 12, fastening piece 13 and linkage structure 14.Wherein, supporting foot 12 is assembled on the strut 11 by linkage structure 14, by fastening piece 13 supporting foot 12 is anchored on strut 11 again.
Supporting foot 12 supports on the ground, and it is used for to the described strut 11 of upper support.In the present embodiment, supporting foot 12 comprises the matrix 20 that is positioned at its center, and by the radially symmetrical pair of support arms 21 of extending of matrix 20, the quantity of support arm 21 is not limited to a pair of, can be provided with as required.The end of support arm 21 is equipped with castor 22 and is supported in ground, thereby desk or worktable etc. can be slided on ground.In the present embodiment, matrix 20 is cylindrical shape, is preferably formed by the metal casting moulding, and its center is provided with a passage 28, and the inwall of passage 28 can be provided with internal thread.Thereby fastening piece 13 passes this passage 28 is fixed in strut 11 with supporting foot 12.
Fastening piece 13 passes linkage structure 14 and extends to strut 11, thereby supporting foot 12 is anchored on strut 11 from supporting foot 12.In the present embodiment, this fastening piece 13 is the allan bolt, but other is suitable equally as fastening structures such as pin, hinge, stationary axle.
This protruding member 15 is fixed in matrix 20 end faces, and preferably, this protruding member 15 and matrix 20 are by the moulding of metal integrally casting.This protruding member 15 extends to form several projections 17 around the central shaft 19 or the fastening piece 13 of stand bar structure 10 parallel to an axis, and each projection 17 is spaced apart at an angle with respect to central shaft 19 or fastening piece 13.In the present embodiment, totally three projections 17, it is one circular that its bottom forms, and each projection is spaced apart along central shaft 19 or fastening piece 13 equal angles ground.Wherein, each projection 17 roughly is dentation, comprises top 24, bottom 25, and the middle transitional region that connects top 24 and bottom 25: curved portions 26.
During assembling, strut 11 is installed on the matrix 20 of supporting foot and the maintenance center coaxial, at this moment, each projection 17 of protruding member 15 is inserted the positioning hole 18 of the pedestal 20 that is arranged in strut 11 respectively and is fixed in wherein, at last, the screw channel 27 at screw channel 28 and pedestal 16 centers is passed in clamping bolt 13 self-supporting pin matrixes 20 bottoms, fastening by being meshing with each other between the screw thread, thereby supporting foot 12 is installed in strut 11 lower ends, forms leg device 10.
In another embodiment, protruding member 15 is welded on the internal surface 23 of strut 11, and the matrix 20 integrally casting moulding of pedestal 16 and supporting foot 12 are same, the projection 17 of protruding member 15 is inserted respectively in the positioning hole 18 of pedestal 16, thereby carries out stationary positioned.Undertaken fastening by bolt 13 at last.
Because of the coupling between protruding member 15 and the pedestal 16, and the effect of fastening piece 13, make supporting foot 12 of the present utility model be fixedly mounted in strut 11 lower ends, even supported worktable or desk are moved, when supporting foot clashes into other object, supporting foot 12 also not can and strut 11 between produce angle displacement or relative movement, thereby can reduce even avoid damage to linkage structure 14.
In addition, between the several projections 17 of the protruding member 15 of linkage structure 14 and spaced apart at an angle between some positioning holes 18 of pedestal 16 with respect to central shaft 19, therefore, can carry out the installing and locating of some angles between protruding member 15 and the pedestal 16, and when being fixed on supporting foot 12 on the strut 11 by this linkage structure 14, with respect to central shaft 19, supporting foot 12 has the mounting point of a plurality of angles, also can carry out angular adjustment to supporting foot 12 as required.Therefore bring great convenience to the user.
