Abstract
The utility model relates to an assembled nut for connecting sheet of chair armrest, comprising a nut main body. The utility model is characterized in that a sleeve the opening of which is butt connected with a screw hole is extended from the nut main body along the axial direction to from an assembled nut which is used for arranging a bolt axially; and sleeve is rightly able to pass through a through hole positioned on the connecting sheet. As the nut and the sleeve are integrated into a whole, when in mounting, no attention has to be paid on the connection between the sleeve and the nut firm or not, thereby simplifying the mounting procedure. Besides, the sleeve and the nut can not release from each other when a bolt is inserted into or after a long time use.
Description
[technical field]
The utility model relates to a kind of nut, especially a kind of office chair handrail connecting sheet assembled nut that is used for.
[background technique]
The existing office chair handrail connecting sheet assembled nut that is used for, for nut can be fixed in the perforation of connecting sheet, other establishes the sleeve pipe that a connecting piece perforation is complementary, this sleeve pipe one end is done axially to be connected by screw thread with nut, the other end then passes the perforation rivet clasp on connecting sheet, when handrail was installed, screw passes nut and sleeve pipe is shot armrest portion, on the handrail fixed seat.But, because sleeve pipe is connected with nut thread, so when mounted, needs to detect between sleeve pipe and the nut and whether tighten, make operation become complicated; In addition, in the process that screw is shot, very likely make to be connected between sleeve pipe and the nut to become loosening; And in daily using process, through shaking of seat and handrail, with the passing of time sleeve pipe and as easy as rolling off a log getting loose of being connected of nut.So above-mentioned nut has further improved needs.
[summary of the invention]
For addressing the above problem, the purpose of this utility model is to provide and can simplifies working process, and can reach the firm lasting office chair handrail connecting sheet assembled nut that connects effect.
The utility model is achieved in that a kind of office chair handrail connecting sheet assembled nut, comprise a nut body, it is characterized in that nut body extends the sleeve that an opening docks with tapped hole vertically, form one and can supply screw to make the assembled nut that axially wears, the big I of described sleeve is just passed the set perforation of handrail connecting sheet.
As the further improvement of such scheme, it is characterized in that the nut external diameter is big than sleeve outer diameter.
As the further improvement of such scheme, it is characterized in that when the perforation on the connecting sheet is polygonal the polygonal that the outer wall shaped design of sleeve root becomes to match.
Principle and advantage of the present utility model is described below: because nut and sleeve are one-body molded, so when mounted, need not to detect between sleeve and the nut and whether tighten, simplified installation procedure, and screw shoot or long-term using process in, it is loosening that sleeve and nut can not become.

[embodiment]
Referring to figs. 1 to Fig. 8, the utility model is by a nut body 1, and one the circular sleeve that extends axially out along nut body 2 form, sleeve 2 openings dock with tapped hole, form one and can supply screw to make the assembled nut that axially wears, and described sleeve 2 big I are just passed square perforation 4 set on the handrail connecting sheet 3, during installation, by the die stamping socket port with the sleeve rivet clasp on link 3, end on connecting sheet 3 for making nut 1 top, nut 1 external diameter is big than sleeve 2 external diameters.
Because the perforation 4 that wears for sleeve 2 on the connecting sheet is square, for prevent that circular sleeve 2 from rotating in perforation 4, the outer wall shaped design of sleeve root 5 becomes regular hexagon, make the sleeve root enter perforation 4 o'clock, pair of parallel face and interior parallel the combining closely of pair of parallel face of square perforation are arranged, nut integral body can not be rotated relative to connecting sheet 3.Certainly the perforation 4 of connecting sheet 3 is not limited to squared design, also can be other shape-designings, and the moulding of sleeve root 5 outer walls is can be designed to quadrilateral or Octagon etc. under the square situation in connecting sheet perforation 4.
Claims (3)
1, office chair handrail connecting sheet assembled nut, comprise a nut body, it is characterized in that nut body extends the sleeve that an opening docks with tapped hole vertically, form one and can supply screw to make the assembled nut that axially wears that described sleeve size just can be passed the set perforation of handrail connecting sheet.
2, office chair handrail connecting sheet assembled nut according to claim 1, it is characterized in that: the nut external diameter is big than sleeve outer diameter.
3, office chair handrail connecting sheet assembled nut according to claim 1 and 2 is characterized in that when the perforation that wears for sleeve on the connecting sheet is polygonal the polygonal that the outer wall shaped design of sleeve root becomes to match.
