Abstract
Description
Technical Field
[0001] The present application relates to the technical field of furniture chairs, and in particular to an iron furniture chair. Background Art
[0002] Iron furniture chairs are more of handicrafts placed in the courtyard. However, due to the relatively heavy material of iron, currently on the market, in order to facilitate transportation, iron furniture chairs are often designed with many hollow combinations or many bent rod combinations.
[0003] However, this hollow combination or bent rod combination design will result in a weaker load-bearing strength of the furniture chair. When a heavier person sits down, the furniture chair may become deformed and its service life may be reduced. Therefore, further improvement is needed. Utility Model Content
[0004] In order to improve the load-bearing capacity of the iron furniture chair, the present application provides an iron furniture chair.
[0005] The present application provides an iron furniture chair, which adopts the following technical solution:
[0006] An iron furniture chair comprises a seat, a chair back arranged on the seat and armrests arranged on the seat, the seat comprises a seat board connected to the chair back and a plurality of support legs fixedly connected to the lower surface of the seat board, a fishing line is arranged on the surface of the chair back away from the seat board, both ends of the fishing line are wound around the front side of the seat board and extend to the support legs to be fixed to the support legs away from the chair back, and a plurality of fishing lines are arranged at intervals along the height direction of the chair back.
[0007] By adopting the above technical solution, when a force is applied to the chair back, a plurality of fish wires are provided. Since both ends of the fish wires are wound around the front of the seat board and fixed to the supporting legs, the applied force can be shared to improve the bearing capacity of the chair back and reduce the possibility of deformation of the iron furniture chair, that is, to further improve the service life of the iron furniture chair.
[0008] Preferably, the chair back is hinged to the chair seat.
[0009] By adopting the above technical solution, since the chair back is hinged to the seat, when the passenger sits on the seat, the fishing line is wound around the seat board, and the passenger's own gravity can be used to drive the chair back closer to the passenger's back, so that the chair back is not easy to deform backwards and break when under pressure, thereby indirectly improving the service life of the iron furniture chair.
[0010] Preferably, the armrest comprises two connecting rods both fixedly connected to the edge of the seat plate and a cross bar arranged between the two connecting rods.
[0011] By adopting the above technical solution, since the chair back is hinged to the seat, the armrest includes two connecting rods and a cross rod to adapt to the chair back and seat that are hingedly arranged, leaving space for the chair back to move.
[0012] Preferably, the fishing line includes, from the middle toward both ends, a first section arranged on the chair back, a second section arranged between the chair back and the seat, a fourth section in the horizontal direction parallel to the seat, and a third section connected to the supporting leg, and two of each of the second section, the third section and the fourth section are provided.
[0013] By adopting the above technical solution, by providing a third section wound around the seat, the length of the fishing line can be increased, and it can be arranged parallel to the original first section, which can share the gravity applied to the seat, thereby further improving the load-bearing capacity of the iron furniture chair.
[0014] Preferably, the first sections of adjacent fishing lines are arranged in a staggered overlapping manner, and the length direction of the first sections is inclined to the length direction of the chair back.
[0015] By adopting the above technical solution, adjacent first sections are arranged in a staggered overlap, and can be woven into a net shape with a plurality of fish threads. During use, the friction force of adjacent fish threads can further increase the bearing capacity of the iron furniture chair.
[0016] Preferably, the length direction of the fourth segment is parallel to the length direction of the first segment.
[0017] By adopting the above technical solution, by making the length direction of the fourth section parallel to the length direction of the first section, a plurality of fourth sections can be arranged in an overlapping and staggered manner below the seat plate.
[0018] Preferably, the fishing line is also wound around a side of the armrest away from the seat.
[0019] By adopting the above technical solution, the fish wire is wound around the side of the armrest away from the seat to further increase the length of the fish wire and share the gravity applied to the seat. By winding it around the armrest, the load-bearing capacity of the iron furniture chair can be further improved.
[0020] Preferably, the chair back and the seat are both hollow, and a surface of the chair back away from the seat and a lower surface of the seat are both provided with reinforcing mesh plates, and a threading space for the fishing line to be threaded is reserved between the chair back and the seat and the reinforcing mesh plates.
[0021] By adopting the above technical solution, the weight of the whole iron furniture chair can be reduced by hollowing out, and by providing a reinforcing mesh plate, the fish thread is threaded in the threading space to reduce the possibility of cuts during transportation when the fish thread is exposed, or the possibility of strangulation marks after being pressed and squeezed by the passengers during riding. The reinforcing mesh plate can further increase the bearing strength of the iron furniture chair.
[0022] In summary, the utility model has the following beneficial effects:
[0023] 1. By providing a plurality of fish wires, both ends of the fish wires are wound around the front of the seat board and fixed to the supporting legs to share the applied force, thereby improving the bearing capacity of the chair back and reducing the possibility of deformation of the iron furniture chair, that is, further improving the service life of the iron furniture chair.
[0024] 2. The chair back is hinged to the seat. When the passenger sits on the seat, the fishing line is wound around the seat board, and the passenger's own gravity can be used to drive the chair back toward the passenger's back, so that the chair back is not easy to deform backwards and break when under pressure, thereby indirectly improving the service life of the iron furniture chair.
