Specifically, the present embodiment provides an inner frame structure of a chair, which includes a chair plate 20, a chair back 10, and a connecting assembly 30 for connecting the chair plate 20 and the chair back 10;
furthermore, the connecting assembly 30 is detachably and fixedly connected to the bottom edge of the seat back 10, and detachably attached to the edge of the surface of the seat plate 20.
Specifically, the bottom ends of two side edges of the chair back 10 are formed with fixed blocks 11 which are in the same direction as the chair plate 20;
further, the coupling assembly 30 includes two accommodating tubes 31 formed with a cavity and into which the tool fixing block 11 is inserted, and a long rod 32 coupling the two accommodating tubes 31.
In the scheme, the chair back 10 is inserted into the cavity of the accommodating pipe 31 through the fixing block 11 of the chair back to realize the fixed connection of the chair back 10 and the fixing block 11, the long rod 32 is connected with the two accommodating pipes 31 to form a whole, and the connection stability of the whole is improved; in the solution provided in this embodiment, the chair plate 20 and the chair back 10 are connected into a whole by the connecting assembly 30, and the connecting assembly 30 and the bottom edge of the chair back 10 are detachably disposed; according to the scheme provided by the application, the chair plate 20 and the chair back 10 can be separately processed in the processing process of the chair, the processing difficulty is reduced, the integral forming is not needed, meanwhile, the mode is convenient for subsequent transportation, the chair plate 20 and the chair back 10 can be respectively stacked for storage, the space utilization rate in transportation is improved, and the transportation cost is reduced; it should be noted that the chair plate 20 and the chair back 10 do not correspond to each other in the conventional one-to-one manner, and different chair plates 20 and different chair backs 10 can be connected by the connecting assembly 30, so that the assembly flexibility is realized, and the assembly efficiency is improved.
Specifically, the outer side surface of the accommodating tube 31 is attached to the plate surface of the chair plate 20;
furthermore, the chair further comprises a first fixing screw penetrating through the chair plate 20, the accommodating tube 31 and the fixing block 11.
In the above solution, the first fixing screw preferably penetrates the chair plate 20, the accommodating tube 31 and the fixing block 11 from the bottom of the chair plate 20 upwards at a time; since the upper portion of the chair plate 20 is the user contacting portion, and the lower end of the first fixing screw penetrates the fixing block 11 and does not penetrate the fixing block 11, the influence of the first fixing screw on the upper portion of the bottom plate can be reduced.
Specifically, a magnetic attraction component is fixedly arranged on the contact surface of the bottom plate and the accommodating tube 31;
furthermore, the magnetic attraction component is arranged on the bottom plate, the accommodating tube 31 is made of magnetic metal, such as metal iron, and the magnetic attraction component realizes the quick positioning of the connecting component 30, when the connecting component 30 is close to the specified position of the bottom plate, the magnetic attraction component can enable the bottom plate and the accommodating tube 31 to be quickly spliced, so that the splicing efficiency is improved, and meanwhile, the connection stability is also improved; in addition, magnetism is inhaled the subassembly and is realized preliminary connection back, also for subsequent screw perforation is fixed provides a stable basis, further promotes the efficiency of assembling.
The accommodating tube 31 is connected with the fixing blocks 11 at two sides of the chair back 10, but the mode is only two-side fixing, the connection stability between the chair back 10 and the long rod 32 is deficient, and in order to solve the technical problem, the embodiment provides the following technical scheme:
specifically, the long rod 32 is connected with the chair plate 20 through a buckle structure 40 formed on the contact surface;
further, the snap structures 40 are evenly distributed along the length direction of the long rod 32;
further, the snap structure 40 is formed as a snap protrusion formed on the bottom end of the chair back 10 and a snap groove formed on the long bar 32 to match with the snap protrusion.
