20130161472 | Telescopic Stand with Chain-type Lifting and lowering function - A telescopic stand includes an outer tube, an inner tube, a chain, a housing, a driven member, a driving member, and a safety latch. The chain is secured on the inner tube. The housing is secured on the outer tube. The driven member is rotatably mounted in the housing and has a chainwheel and a worm gear. The chainwheel has engaging teeth meshing with the chain. The driving member is rotatably mounted in the housing and has a worm meshing with the worm gear. The safety latch is mounted on the housing and is movable to lock the driven member. Thus, when the inner tube bears a heavy load, the chainwheel co-operates with the chain to withstand the larger force applied by the inner tube and will not be worn or broken due to a larger rotation force. | 06-27-2013 |
