Abstract

The utility model relates to a plastic armrest of a revolving chair, which belongs to fittings of a revolving chair used for offices and families, and the utility model is made of leather substances and plastic steel. The plastic armrest is composed of frame strips; assembly holes are arranged in the back frame strips and the bottom frame strips; metal rings are inserted into the assembly holes. Owing to the high mechanical strength of the metal rings, when the utility model is connected and screwed by fastening pieces, the utility model can bear extrusion and shrinking, the shearing force can be bore, and the utility model can meet the requirements of the connection and the assembly of the armrest and a chair frame.

Description

The swivel chair plastic handrail

The utility model relates to the swivel chair accessory, particularly relates to the swivel chair plastic handrail, is suitable for office and family and uses.

With the swivel chair that the plastic-steel leather substance is made, have handsome in appearance generously, it is comfortable to be seated, and the rotatable human body that makes faces toward different directions, writes reading, computation, talks characteristics such as convenient with the people, is widely used in office and the family.The handrail of such swivel chair slightly is tetragonal frame structure, is shaped on pilot hole in moulding and the underframe bar thereafter, by securing member handrail is installed on the chair frame in the pilot hole, and therefore, the outer end of pilot hole needs the fastener cap mouth of an expansion.Because handrail adopts plastics to make, the pilot hole mechanical strength is stressed limited, " pine " if install, and it is not firm to connect, if tension is installed, often with the working of plastics crush injury, can cause consequences such as fragmentation.

The purpose of this utility model is the defective that overcomes prior art, provides a kind of pilot hole mechanical strength good, can satisfy the swivel chair plastic handrail that securing member is tightened the assembling needs.

The technical scheme of the utility model swivel chair plastic handrail is: a kind of plastic handrail of forming by the frame bar, in back moulding and underframe bar, be shaped on pilot hole, and it is characterized in that being embedded with in the pilot hole becket.

Swivel chair plastic handrail of the present utility model, becket is that carbon steel or stainless steel or materials such as copper material or aluminium alloy are made in its pilot hole.

The utility model discloses the plastic handrail on a kind of swivel chair, in the pilot hole of the back moulding of handrail and underframe bar, be embedded with becket, becket mechanical strength height, when adopting securing member to tighten, be not afraid of extruding and take out tightly, and bear shearing force, satisfy the needs that handrail and chair frame are linked and packed.

Fig. 1 is that the utility model swivel chair plastic handrail master looks schematic diagram;

Fig. 2 is that the utility model swivel chair plastic handrail A-A is to schematic diagram.

Below in conjunction with Fig. 1-Fig. 2 embodiment of the present utility model is done detailed explanation.

The utility model relates to the swivel chair plastic handrail, is slightly to be the structural shape that square is made up of moulding, because of handrail is installed on the chair frame by securing member usually.So, in the back moulding 4 of swivel chair plastic handrail 1 and underframe bar 5, be shaped on pilot hole 2.For mechanical strength and the connection reliability that improves pilot hole, at the pilot hole 2 position built-in metal rings 3 of plastic handrail.The manufactured materials of becket 3 mainly is steel, as medium carbon steel, but also can adopt stainless steel or copper material or aluminum alloy materials etc.

Claims

1, swivel chair plastic handrail, a kind of plastic handrail of being made up of the frame bar is shaped on pilot hole (2) in back moulding (4) and underframe bar (5), it is characterized in that being embedded with in the pilot hole (2) becket (3).

2, swivel chair plastic handrail as claimed in claim 1 is characterized in that becket (3) in the pilot hole (2) is that carbon steel or stainless steel or copper material or aluminum alloy materials are made.
