Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
As shown in fig. 1-4, the utility model provides a can dismantle chair frame, this can dismantle chair frame includes that central structure 1 made by the metal and ring locate central structure 1 around at least three wooden chair leg 2, central structure 1 includes that barrel 11 and ring locate a plurality of supporters 12 of barrel 11 outer wall, the quantity of supporter 12 equals with the quantity of chair leg 2, the central axis of supporter 12 is the acute angle setting with the central axis of barrel 11, chair leg 2 can dismantle with supporter 12 and be connected.
The central structural part 1 is made of metal and has higher strength, and is connected with a seat board of a seat through a cylinder body 11, and a plurality of support bodies 12 on the outer wall of the cylinder body 11 are connected with a plurality of chair legs 2, so that the connection parts of the chair legs 2 are not easy to break; through the dismantled connection of chair leg 2 and supporter 12, realize being connected between wooden chair leg 2 and the central structure 1 of metal, improve the support intensity of seat, and easy dismounting, it is less to occupy the volume after each parts is dismantled, and storage and logistics cost are lower.
The angle between the central axis of the support body 12 and the central axis of the cylinder 11 is 40-55 degrees. For example, the angle between the central axis of the support body 12 and the central axis of the cylinder 11 may be 40 °, 42 °, 45 °, 48 °, 50 °, 52 °, 55 °, or the like. In the angle range, the support legs 21 can enable the detachable chair frame to be placed stably and not to shake easily after being installed, and the detachable chair frame has a good support effect.
The cross-sectional shape of the support body 12 is rectangular. Specifically, the support body 12 may be made of a rectangular pipe, which may be a steel pipe, an iron pipe, or the like. One end of the support body 12 is configured to be matched with the outer wall of the cylinder 11, and the support body 12 and the cylinder 11 are welded into a whole.
The one end of supporter 12 that is not connected with barrel 11 has seted up spliced eye 121, and chair leg 2 includes supporting leg 21 and connects in the spliced pole 22 of supporting leg 21 upper end, and spliced pole 22 cooperates with spliced eye 121 to realize chair leg 2 and supporter 12's the dismantlement and be connected.
The cross-sectional area of the support leg 21 gradually decreases from one end close to the support body 12 to one end far from the support body 12. The end face size of the supporting leg 21 at the end connected with the plug column 22 is larger than that of the plug column 22, so that after the plug column 22 is inserted into the supporting body 12, the end face of the supporting leg 21 can be abutted against the end face of the supporting body 12 and used for limiting the insertion distance of the plug column 22.
In order to ensure the stability of the connection between the support body 12 and the legs 2, the detachable chair frame further comprises a locking member which connects the support body 12 and the insertion column 22. After the chair legs 2 and the supporting body 12 are inserted, the chair legs 2 and the supporting body 12 are locked through the locking piece, the reliability of connection of the chair legs 2 and the supporting body 12 is guaranteed, and the chair legs 2 cannot fall off in the moving process; when the chair legs 2 need to be detached from the supporting body 12, the locking pieces are unlocked firstly, so that the chair legs 2 can be easily pulled away from the supporting body 12, and the detachment and installation processes are very convenient.
The retaining member comprises a bolt 3 and an embedded nut 4, a connecting hole 122 is formed in at least one side face of the support body 12, the embedded nut 4 is arranged on the surface of the insertion column 22 opposite to the connecting hole 122, and the bolt 3 can penetrate into the connecting hole 122 and then is connected with the embedded nut 4 in a matched mode. The embedded nuts 4 are embedded in the surface of the wooden chair leg 2, so that the chair leg 2 and the supporting body 12 can be connected through the bolts 3. The axes of the connecting hole 122 and the embedded nut 4 are perpendicular to the axis of the inserting column 22, so that the inserting column 22 is not easy to be pulled out from the supporting body 12 after being connected, and the stability of connection between the supporting body 12 and the chair leg 2 is improved.
In order to adjust the height of the seat, the number of the connecting holes 122 may be multiple, and the multiple connecting holes 122 are arranged along the axial direction of the supporting body 12, and the bolt 3 is selectively inserted into one of the connecting holes 122 and then is cooperatively connected with the embedded nut 4. The distance of insertion of the legs 2 into the support body 12 can thereby be adjusted, and the height of the seat adjusted.
It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
