Abstract
The utility model discloses an assembled footstand which comprises a central stand part. A plurality of mutually independent foot parts are connected to the central stand part through a connecting mechanism which comprises a plurality of dovetail grooves arranged on the side wall of the central stand. The end walls of the foot parts are provided with convex dovetail ribs corresponding to the dovetail grooves, the foot parts are clamped in the dovetail grooves through the convex dovetail ribs, and the dovetail grooves and the convex dovetail ribs are all in wedge structures. A structural form of separated manufacture is adopted by the footstand so as to ensure that the central stand part and the foot parts can be processed by a small die casting machine, die processing is simple, and the production cost is greatly reduced. Moreover, the packing volume can be reduced, and transportation expenses are also reduced.
Description
Technical field
The utility model relates to seat, is specifically related to the runners of seat.
Background technology
In office at present or his runners such as aluminium alloy seat that not closes usefulness generally all is monoblock cast, as figure one, process bigger die casting machine and the very large die casting of so whole runners 01 needs, the production cost height, and the mould manufacture difficulty is big.And finished product packing is very big, has increased freight, and 02 is central support tube among the figure.
The utility model content
The utility model the technical problem that will just solve just provide a kind of simple in structurely, can reduce production costs greatly, and can reduce packaging volume, reduce the loading and unloading type runners of freight.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: the loading and unloading type runners is characterized in that: comprise centre mount portion, be connected with the foot of several independent in the centre mount portion by bindiny mechanism.Centre mount portion separates manufacturing with foot like this, its assembling is joined together during use again, has simplified mould structure, greatly reduces production cost, and can reduce packaging volume, reduces freight.
Preferably, the distolateral universal wheel that is provided with outside the described foot.
Preferably, described bindiny mechanism comprises that ring is located at the some dovetail grooves on the centre mount sidewall, and described foot end wall is provided with the dovetail convex tendon corresponding with described dovetail groove, and foot is installed in the dovetail groove by described dovetail convex tendon.Assemble very easy.
Improved, described dovetail groove and dovetail convex tendon are wedge structure, and this structure can directly tighten, and is more stable after clamping.
Improved, described centre mount portion is a tubular structure, and foot is by the inboard hollow of dovetail convex tendon, and the dovetail groove and the dovetail convex tendon of described centre mount portion sidewall are provided with bolt hole, are coated with fastening bolt in the bolt hole.The connection that increases centre mount portion and foot is stable.
Improved, also be provided with the crescent cushion block between the inner tubal wall of described bolt and centre mount portion, the inner tubal wall anchor ring of the meniscus level of crescent cushion block and centre mount portion matches.Increase the lifting surface area of bolt like this, bolt can be only in the inner tubal wall anchor ring clamping of edge and centre mount portion, and it is loosening to avoid skidding.
Improved, the crescent cushion block is provided with groove with respect to the back side of meniscus level.But in the hexagonal end two sides card entry slot of bolt, bolt can and then not change during fastening nut like this, makes things convenient for bolt to tighten.
Improved, described centre mount portion is connected with the central support tube one of seat.
Preferably, described foot is 3～6, the quantity of described dovetail groove is provided with can be more than foot's quantity, as long as it guarantees at hoop foot to be installed evenly, can consider like this when breaking down a foot can be conveniently to the remaining step installation site of arranging again, chair can be reused, reduce maintenance and scrap cost.
The utility model adopts technique scheme, and seat leg adopts the version of separately making, and centre mount portion and foot can be processed with small-sized die casting machine, it is single that Mould Machining also becomes tube, can reduce production costs greatly, and can reduce packaging volume, reduce freight.
