This is on broken terrain and impracticable, and structure is relative complex, complicated structure mean manufacturing cost rising and
The raising of probability of damage and more frequently safeguard, it is impossible to realize automatically regulation.
Utility model content
The purpose of this utility model is to provide a kind of table leg telescoping mechanism, asked with solve to propose in above-mentioned background technology
Topic, possessed beneficial effect are；Mechanism structure is compact, reliable operation, completes to stretch using pinion and rack, applies in table
Structure can be made greatly simplified on chair so that mobile desk is more convenient, between driving gear and motor, does not install other transmissions
Mechanism, kinetic energy transmission efficiency are high.
To achieve the above object, the utility model provides following technical scheme：A kind of table leg telescoping mechanism, including driving tooth
Wheel, table leg and pedestal, the both sides of the table leg are provided with chute, and the slide rail that pilot sleeve is set by inner side is arranged on table leg
Outside, castor is fixed with the downside of the table leg, it is plane that the pilot sleeve, which has one side, and rack is provided with plane,
The driving gear engages connection with the tooth on rack by tooth, and the both sides of the pedestal are provided with axis hole, and axle passes through axle
Hole is fixed on pedestal by nut.
Preferably, the castor is arranged on pedestal by axle by roller and formed.
Preferably, the both sides of the axle are provided with screw thread.
Preferably, the driving gear is arranged in the rotating shaft of motor.
Preferably, driving gear is installed, and driving gear is located at the upper end of pilot sleeve on the pilot sleeve.
Compared with prior art, the beneficial effects of the utility model are：Mechanism structure is compact, reliable operation, utilizes gear
Rackwork is completed to stretch, and applying can make structure greatly simplified on tables and chairs so that mobile desk is more convenient, in driving gear
Between motor, other transmission mechanisms are not installed, kinetic energy transmission efficiency is high, and passes through chute and cunning between pilot sleeve and table leg
Rail is attached, and can avoid the dislocation of pilot sleeve, improves the accuracy that pilot sleeve moves on table leg, additionally mounted
There is castor, facilitate the movement of desk, installed by axle, be convenient for changing after roller damage, table leg telescoping mechanism can be extended
Service life.
