Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of seats, and particularly relates to an armrest reinforcing structure and a seat. BACKGROUND

[0002] Dining chairs are common seats in dining places such as canteens and restaurants. The dining chairs are usually simple in structure, practical and simple in design, and do not use too many decorations, so that the visual experience is simplified, and people feel comfortable and relaxed. At the same time, the dining chairs are convenient for daily maintenance and management, and are also convenient for manufacturers to mass-produce.

[0003] The armrest of the existing dining chair is usually a plate-shaped structure, and the armrest and the backrest are connected to form a complete U-shaped plate, which is simple in structure. The armrest of this type of dining chair is usually made of plastic material and is made by blow molding process. The blow molding armrest has a low manufacturing cost and is convenient for mass production.

[0004] However, the blow molding armrest has the following problems: since the blow molding part is a hollow structure, it is slightly insufficient in strength compared to a solid wood board or a plastic board formed by compression molding. When a user sits on the seat and places his hand on the blow molding armrest, the blow molding armrest is subjected to downward pressure and outward thrust, and is easily bent and deformed downward and outward, so that the support is poor. SUMMARY

[0005] In view of the above defects or deficiencies in the prior art, it is desirable to provide an armrest reinforcing structure and a seat. When the armrest body is subjected to downward pressure or outward thrust, the reinforcing part shares the load with the armrest body, thereby reducing the load of the armrest body, preventing the armrest body from being bent and deformed after being subjected to stress, and effectively improving the support strength of the armrest body.

[0006] The effect of the utility model is achieved as follows:

[0007] In a first aspect, the application provides an armrest reinforcing structure, which comprises an armrest body. The armrest body is a plate-shaped structure made by blow molding. A reinforcing part is arranged on one side wall of the armrest body. The reinforcing part comprises a support part arranged in a horizontal direction and a reinforcing part arranged in a vertical direction. The support part extends upward or downward by at least one reinforcing part. The reinforcing part is configured to improve the support strength of the armrest body.

[0008] Further, the support part is arranged at the lower part of the armrest body, and the front and rear ends of the support part are both bent upward to form the reinforcing part. The front and rear parts of the armrest body can be supported by the reinforcing part, thereby effectively improving the support strength of the armrest body. Moreover, the support part is arranged at the lower part of the armrest body, so that the lower part of the support part has higher strength and is less likely to shake or deform after being connected to the seat, thereby having better stability.

[0009] Further, the support part is arranged at the upper portion of the handrail body, and the front and rear ends of the support part are both bent downward to form reinforcing parts. The front and rear portions of the handrail body can also be supported by the reinforcing parts, effectively improving the support strength of the handrail body.

[0010] Further, the reinforcing parts are arranged obliquely relative to the support part. The reinforcing parts can span the front and rear sides of the handrail body, so that only one reinforcing part is needed to improve the strength of the front and rear portions of the handrail body.

[0011] Further, the support part protrudes towards one side of the handrail body and has a plug-in part, and a plug-in hole is formed in the handrail body in correspondence with the plug-in part; when the reinforcing part is connected to the handrail body, the plug-in part is plugged into the plug-in hole. This further improves the connection strength between the reinforcing part and the handrail body, and the external force applied to the handrail body is more easily transmitted to the reinforcing part through the plug-in part, further improving the support strength of the handrail body.

[0012] Further, a mounting groove is recessed in the side wall of the handrail body, and the reinforcing part is connected in the mounting groove. This not only improves the connection strength between the reinforcing part and the handrail body, but also makes the reinforcing part and the handrail body appear as a whole, improving the appearance of the handrail body.

[0013] In a second aspect, the application provides a seat, which comprises a seat cushion and a handrail reinforcing structure. The seat cushion comprises a seat pad and a frame supported at the bottom end of the seat pad, and the handrail body is connected to the left and right sides of the frame, so that the seat cushion is surrounded by the handrail body on both sides. By surrounding the seat cushion with the handrail body, the seat cushion is hidden inside the handrail body, and only the handrail body on both sides of the seat is visible, making the overall appearance of the seat more simple and beautiful.

[0014] Further, the reinforcing part is arranged on the side of the handrail body away from the frame, the plug-in part of the reinforcing part penetrates through the handrail body and is connected to the frame, a first connecting hole is formed in the plug-in part, a second connecting hole is formed in the side wall of the frame, and the first connecting hole and the second connecting hole are fixed by a bolt in series, so that the handrail body is clamped between the frame and the reinforcing part. The handrail body is connected by the reinforcing part and the frame with high strength, so that the connection strength between the handrail body and the frame is higher; and the handrail body is clamped between the frame and the reinforcing part, so that when a user sits on the seat and applies an outward pushing force to the handrail body, the reinforcing part can better provide support to the inward handrail body, making the support strength of the handrail body better.

[0015] Further, a horizontal avoiding groove is formed in the side wall of the handrail body, and the avoiding groove is configured to avoid the seat pad. The seat pad can be fixed from the avoiding groove, which not only makes the seat pad less likely to slip off the seat cushion, but also makes the installation and removal of the seat pad more convenient.

[0016] In a third aspect, the application provides a seat, comprising a seat cushion and a handrail reinforcing structure, the seat cushion comprising a seat pad and a frame supported at the bottom end of the seat pad, and a handrail body connected to the left and right sides of the seat cushion and connected to the top end of the frame at the bottom end of the handrail body. When the handrail body is pressed, the frame can share the stress of the handrail body, thereby improving the support strength of the handrail body.

[0017] The handrail reinforcing structure and the seat provided by the application can effectively improve the support strength of the handrail body by arranging reinforcing members on the side surface of the handrail body, so that the reinforcing members can share the stress of the handrail body when the handrail body is subjected to downward pressure or outward thrust, thereby reducing the load on the handrail body and preventing the handrail body from bending and deforming after being subjected to stress. In addition, the reinforcing members are connected by the supporting members and connected to the handrail body by the supporting members, so that the overall strength of the reinforcing members is good and the reinforcing members are prevented from shaking relative to the handrail body.
