Detailed Description
The present invention will be further described with reference to the following examples.
Examples
As shown in fig. 1-4, the armrest mechanism of a folding chair comprises an armrest 1, a connecting rod 2 fixed on the armrest 1, and an armrest fixing device, wherein the armrest fixing device is connected to the connecting rod 2, the armrest fixing device comprises a fixed frame 3 movably connected to the connecting rod 2, a movable block 4 is arranged on the fixed frame 3, a pushing member 5 for applying pressure to the movable block 4 in the direction of the connecting rod 2 is movably connected to the fixed frame 3, the pushing member 5 has a pressing state and a decompression state, and the pushing member 5 pushes the movable block 4 against the pushing member 5 in the pressing state, so that the movable block 4 is abutted against the connecting rod 2; the pushing piece 5 is in a decompression state, and the movable block 4 has a movable gap between the pushing piece 5 and the connecting rod 2. In this embodiment, the direct 5 roof pressure movable blocks 4 of piece that will push up through the direct roof pressure connecting rod 2 of movable block 4, make mount 3 can produce the locking with connecting rod 2, the utility model discloses simple structure, the part is few, the production assembly of being convenient for.
In order to facilitate the user to lock the handrail fixing device, the pushing piece 5 is movably connected with the fixing frame 3 through a pin shaft. In this embodiment, the pushing member 5 is a rotating member, and a handle is connected to the circumference of the rotating member, so that a user can conveniently lock and unlock the handrail fixing device.
In order to enable the pushing piece 5 to play a pushing role, the pushing piece 5 is eccentrically arranged on the fixed frame 3. The movable block 4 is pressed by the position with larger eccentricity of the pushing piece 5, and the pushing piece 5 is in a decompression state when the position with smaller eccentricity is close to the movable block 4.
The connecting rod 2 is a circular tube. The surface of the movable block 4 contacting with the connecting rod 2 is an arc-shaped groove structure jointed with the surface of the connecting rod 2. Due to the design of the arc-shaped groove of the movable block 4, the joint area of the movable block and the connecting rod 2 is larger, the friction surface is increased, and the braking effect is better.
