At present; often can use five-pointed star chair pin in the swivel chair field; but the institute of this five-pointed star chair pin takes up space larger; packing and logistics space are larger; larger on the production cost impact; so having some removable five-pointed star chair leg structures to meet occurs; publication number is that the Chinese utility model patent of 201509927U discloses dismountable swivel chair five-star support legs; although can realize dismounting; but pass through locking device; operate such as screw nut etc., such structure is so that disassembly process is more loaded down with trivial details, and locking device can injury to the chair pin in addition.
The utility model content
The purpose of this utility model provide a kind of can stabilized structure, the removable five-pointed star chair leg structure of easy accessibility.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of removable five-pointed star chair leg structure, comprise the pentalpha spare that is connected with the chair body and can realize 5 chair pin of dismounting with pentalpha spare, pentalpha spare is provided with 5 openings, the chair pin is provided with the built-in end that is used in conjunction with opening, is provided with vertical latch-up structure and lateral locking structure between opening and the chair pin.Fastening degree and anti-pressure ability after the latch-up structure on the both direction is realized dismounting and guaranteed to install.
As to of the present utility model preferred, vertically latch-up structure comprises first vertical sticking department and second vertical sticking department, first vertical sticking department comprises pentalpha spare along the shoulder of opening direction and is positioned on the built-in end supporting surface with the shoulder effect, second vertical sticking department comprises and is arranged on five pin type star polygon work by the draw-in groove of opening inboard and is arranged on the fixture block of the built-in end outside and draw-in groove effect, and the lateral locking structure comprises and is arranged on pentalpha spare stopping groove and being arranged on built-in end both sides and the block that stops that groove cooperates along the opening both sides.Fixture block embeds in the draw-in groove, guarantees that the chair pin is fixing longitudinally, and chair pin pressure longitudinally when alleviating arranging of independent fixture block by arranging of shoulder and supporting surface again stops that groove and block can realize that horizontal locking is unlikely to the chair pin and breaks away from pentalpha spare.
As to of the present utility model preferred, block is provided with the first spigot surface, stops that groove is provided with the first groove face that cooperates with the first spigot surface, and fixture block is provided with the second spigot surface, and draw-in groove is provided with the second groove face that cooperates with the second spigot surface.This preferably is convenient to pack into pentalpha spare and do not need the instrument that adds or other locking devices of chair pin.
As to of the present utility model preferred, the first spigot surface and the first groove face are arcwall face, and the second spigot surface and the second groove face are arcwall face.
As to of the present utility model preferred, the pentalpha spare outside and chair pin are near the distolateral S shape curved surface that is provided with mutual splicing of embedding.Can alleviate again that the chair pin is vertical to upward pressure, keep the stability of structure.
As to of the present utility model preferred, pentalpha spare is provided with reinforcement at the draw-in groove back.
As to of the present utility model preferred, the back of the body of chair pin is the arc back of the body.
As to of the present utility model preferred, be provided with reinforcement in the back of the body of chair pin.
The beneficial effects of the utility model are: the stability of guaranteeing structure by horizontal and vertical double locking, and guide frame be arranged so that install very simple, by draw-in groove, fixture block, stop that the setting of groove, block can be so that assembly unit need to add locking device or instrument, saved production cost, the setting of other shoulder etc. can both promote chair pin anti-pressure ability greatly, has further strengthened the firm degree of structure.
