A kind of section bar and non section steel linkage structure, comprise section bar termination section, bearing pin, non section steel termination section, its special way is: the side of bearing pin front portion is provided with through hole, and the lateral vertical at bearing pin rear portion is provided with link arm, is provided with along the axial through hole of bearing pin on link arm; Section bar termination section cavity shape, size and bearing pin front portion match, and the sidewall of section bar termination section is provided with through hole, and the through hole of this through hole and bearing pin front portion matches; In non section steel termination section, be provided with the locating slot suitable with bearing pin rear portion, be provided with through hole in locating slot, the through hole on this through hole and link arm is suitable; The anterior section bar termination section inner chamber that inserts of described bearing pin, adopts link by the fastening installation of described through hole; Non section steel termination section locating slot is inserted at bearing pin rear portion, adopts link by the fastening installation of described through hole.
For being installed, one end of link arm is also provided with the fixed groove with the corresponding coupling of link arm in above-mentioned locating slot.
The anterior section bar termination section inner chamber that inserts of above-mentioned bearing pin, adopts screw or rivet by the fastening installation of through hole; Non section steel termination section locating slot is inserted at bearing pin rear portion, adopts screw or rivet by the fastening installation of through hole.
The side of above-mentioned bearing pin front portion is provided with three of through holes, and the sidewall of section bar termination section is provided with three of through holes.
Above-mentioned bearing pin is stainless steel bearing pin.
The beneficial effects of the utility model are as follows:
1, coordinate closely reliably: by the link arm of bearing pin, make the direction of fastening force consistent with installation direction, section bar and non section steel can be strained along installation direction, seam is coordinated closely.
2, installation precision is high: adopt stainless steel bearing pin, can bear large External Force Acting, and coupling design and screw thread fixed installation, Placement is solid and reliable, makes the cabinet framework precision after installing high.
3, good appearance: mounting structure is not exposed to appearance, and product is not had any impact, indefectible, there is no gap, good appearance.
4, applied range: can be applicable to load greatly and the higher bin series products of appearance requirement.
Accompanying drawing explanation
Fig. 1 is structure connection diagram of the present utility model;
Wherein reference character is: 1-section bar; 2-through hole; 3-screw; 4-bearing pin; 5-link arm; 6-non section steel; 7-fixed groove; 8-locating slot.
Embodiment
The purpose of this utility model is to provide a kind of solid and reliable section bar of bin series products and inner connecting structure of non section steel of degree of precision, and the structure after installing does not have any impact to product appearance.The utility model has been used bearing pin 4, section bar 1 and non section steel 2 are linked together, bearing pin 4 used has increased link arm 5 with location and has installed on common bearing pin, one end being inserted into inner chamber of sectional bar, show and guarantee to install positioning precision with section bar inner cavity size one, the other end inserts in locating slot 8 reserved on non section steel 6, and the geomery of locating slot 8 should mate with bearing pin 4 insertion ends.Bearing pin 4 being inserted into inner chamber of sectional bar ends are connected with section bar and are locked by screw 3, insert reserved locating slot 8 ends on non section steel, by screw 3, the link arm of bearing pin 5 and locating slot 8 are installed to locking, between fixed groove 7 and link arm 5 by rational structural design, can before installation, reserve the gap that is provided with 0.5mm, to accurately coordinate with non section steel along installation direction tension section bar end face.The material of bearing pin 4 is conventionally not second to section bar and non section steel, and according to the requirement of design and load, bearing pin 4 can adopt unlike material, and the present embodiment is used stainless steel bearing pin.
Below in conjunction with Figure of description, describe embodiment of the present utility model in detail:
As shown in Figure 1, section bar 1 is hollow lumen, and the sidewall of section bar termination section is processed with three through holes 2; On bearing pin 4, be processed with three corresponding through holes 2, on its link arm 5, have a through hole 2; The non section steel 6 using in Fig. 1 is hornblock, has locating slot 8 on it, has the fixed groove corresponding with link arm 57 and a through hole 2 on the attachment face of locating slot 8, and through hole 2 is arranged in fixed groove 7.During installation, the inner chamber of section bar 1 termination section is inserted in the anterior one end of bearing pin 4, through hole 2 on bearing pin 4 front portions is corresponding with the through hole 2 on section bar 1 termination section inner chamber, and screw 3 is connected with the through hole 2 on bearing pin 4 front portions through the through hole 2 on section bar 1 termination section inner chamber, by section bar 1 and the anterior locking of bearing pin 4; Bearing pin 4 rear portions are pressed correspondence direction and are inserted locating slot 8, and screw 3 is connected with the through hole 2 in locating slot on hornblock 8 through the through hole 2 on link arm 5, by bearing pin 4 rear portions and hornblock locking.Between fixed groove 7 and link arm 5 by rational structural design, can before installation, reserve the gap that is provided with 0.5mm, to section bar 1 termination section and non section steel 6 termination section are strained along installation direction in installation process, in the present embodiment, namely section bar 1 termination section and hornblock are strained along defence line is installed, made seam tight.After installation, section bar 1 and hornblock coordinate closely reliable, and installation precision is high, good appearance.
