Description
Technical field
The utility model relates to a kind of plane jacking system.
Background technology
Often need to use jacking system in the every field such as kitchen guarding, office, the problems such as existing jacking system exists assembling inconvenience, result of use is poor, setting height(from bottom) is large, lift is little.
Authorization Notice No. is that the Chinese patent of CN2910888Y discloses a kind of layered set type automatic lifting/lowering apparatus, this jacking system comprises chopped-off head nut, chopped-off head screw mandrel, chopped-off head lifting rod member, secondary nut, secondary screw mandrel and three grades of screw mandrels, chopped-off head nut is threaded onto on chopped-off head screw mandrel, chopped-off head nut and chopped-off head are elevated rod member and are fixedly connected with, connecting with key makes secondary screw mandrel be connected to chopped-off head screw mandrel, secondary screw mandrel and chopped-off head are elevated rod member and are connected by bearing, secondary nut and secondary screw mandrel are designed to the screw mandrel part being with nut, and three grades of screw mandrels are threaded onto in secondary nut.During work, chopped-off head screw mandrel is driven by worm gear pairs and rotates, chopped-off head screw mandrel rotates and drives chopped-off head lifting rod member and secondary screw mandrel to rise simultaneously, secondary screw mandrel rotates with chopped-off head screw mandrel while rising, secondary screw mandrel rotates and then drives three grades of screw mandrel relative secondary screw mandrels to rise, this jacking system has the function of speed lifting, and it can shorten the half of stroke at minimum mounting distance.
But, in said structure, because secondary screw mandrel and chopped-off head screw mandrel are that set up between by the mode of the sliding block joints such as key connection axially can relative sliding, the circumference annexation that can not relatively rotate, certain friction certainly will be produced during the two relative sliding, the loss of power of motor can be caused and reduce service life and the manufacture difficulty of secondary screw mandrel and chopped-off head screw mandrel; And due to this jacking system when being elevated chopped-off head lifting rod member only in the axial direction up-and-down movement, be non-rotary in circumferential direction, and secondary screw mandrel is both axially liftings, rotates in a circumferential direction together with chopped-off head screw mandrel, need to be established a connection by bearing between such chopped-off head lifting rod member and secondary screw mandrel, and after bearing is set, bearing then bears a big chunk application force of jacking system on lifting direction, easily damages; In addition, because the major part of chopped-off head screw mandrel is set in chopped-off head lifting rod member, therefore only have chopped-off head screw mandrel end could establish a connection with worm gear pairs, namely worm gear pairs entirety needs to be arranged on chopped-off head screw mandrel bottom, and this adds the setting height(from bottom) of jacking system undoubtedly.
