In the above-mentioned competing chair back inner support component of electricity, the annular canister one is equipped with far from one end of limit flange two
Limit flange one.
It limits flange two and limits the mutual synergistic effect of flange one, the locking of front and back may be implemented.
In the above-mentioned competing chair back inner support component of electricity, the limit flange one and limit flange two are parallel to each other.
The structure its be convenient for construction and installation.
In the above-mentioned competing chair back inner support component of electricity, one outer wall of annular canister is equipped with from convex buckle hole and extends to limit
Male part on the flange one of position.
Male part its can play the role of reinforcement.
In the above-mentioned competing chair back inner support component of electricity, the annular canister one and limit flange one are linked together formula knot
Structure.
Which raises structural strengths for integral structure, meanwhile, also further improve production efficiency.
In the above-mentioned competing chair back inner support component of electricity, the annular canister two and limit flange two are linked together formula knot
Structure.
Which raises structural strengths for integral structure, meanwhile, also further improve production efficiency.
In the above-mentioned competing chair back inner support component of electricity, the annular canister one is straight tube structure.The structure its be convenient for
Processing and manufacturing.
Compared with prior art, the advantages of this electricity competing chair back inner support component, is:
1, the design of two outer diameter of annular canister, can reduce contact area in disassembly process, to greatly improve dismounting
The ride comfort of process, virtually improves disassembly efficiency.The design for cooperateing with convex buckle hole and convex buckle, can be further improved dismounting
Efficiency, and can equally ensure the stability of axial lock, avoid obscission.
2, cost is lower.
