Detailed Description

The utility model provides a handrail seat, for making the utility model discloses a purpose, technical scheme and effect are clearer, make clear and definite, and it is right that the following refers to the attached drawing and the embodiment of lifting the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1, the present invention provides an armrest chair, which comprises a chair back 1, a seat 2, and armrests 3 fixed to the seat 2 and the two sides of the chair back 1.

As shown in fig. 1, 2 and 4, the armrest portion 3 includes an armrest plate 31, an armrest seat 32 having a hollow cavity 325, and a support leg 33 fixed to the bottom of the armrest seat 32. The legs may be fixedly attached to the armrest seat 32 by welding or bolts. The top end of the armrest seat 32 is provided with a straight top plate 321, and the top plate and the armrest seat 32 are integrally formed.

As shown in fig. 1, 2, 3, 4 and 5, the top plate 321 is provided with a plurality of card-in openings communicated with the inner cavity 325 of the armrest seat 32. In this embodiment, two card inlets, card inlet 322 and card-in inlet 323, are provided. The bottom surface of the armrest plate 31 is provided with a plurality of clamping blocks 4 corresponding to the clamping inlets, each clamping block 4 is integrally formed by an inverted-L-shaped connecting portion 41 and an inverted-V-shaped clamping portion 42, and in this embodiment, each clamping block 4 is made of a metal elastic sheet. The top end of the connecting part 41 is fixed on the bottom surface of the armrest plate 31 through a screw, and one end of the clamping part 42 is connected with the bottom end of the connecting part 41. When the clamping portion 42 is clamped into the clamping inlet and abuts against the bottom surface of the top plate 321, the bottom surface of the armrest plate 31 is attached to the top surface of the top plate 321.

After the handrail plate 31 is clamped on the handrail seat 32, the top plate 321 is in surface contact with the handrail plate, thereby effectively supporting the handrail plate and promoting the handrail plate to keep a stable state.

As shown in fig. 3 and 5, the inner angle of the engaging portion 42 ranges from 90 ° to 120 °, and the projected length of the engaging portion 42 is larger than that of the card entrance when viewed from the top, so that the design is as follows: even if the handrail plate 31 is moved to the right and then cannot be directly and vertically drawn out, other people are prevented from randomly disassembling the handrail plate. When the handle plate 31 is mounted on the handle seat 32, the handle plate 31 is moved downward and leftward to insert the engaging portion 42 into the engaging opening, and the engaging portion 42 is elastically deformed by the force of the top plate 321 during the process, so that the inner angle of the engaging portion is increased, and the handle plate 31 can be fixed on the handle seat 32 by the engaging action of the engaging block 4 and the top plate 321.
