The invention relates to the technical field of lifting devices, in particular to a son and mother balance lifter. The lifter comprises a rack. The rack comprises a top plate and a bottom plate. A center shaft is vertically arranged between the top plate and the bottom plate in a penetrating mode. A clutch lifting device which drives the center shaft to move up and down is arranged on the rack. A mother wheel assembly capable of rotating horizontally, a driving gear and a son wheel assembly are sequentially arranged at the upper, middle and lower portions of the center shaft. A one-way locking device is connected between the mother wheel assembly and the rack. A first one-way bearing is connected between the driving gear and the center shaft. A first fixing bearing is connected between the son wheel assembly and the rack. A transmission assembly which is matched with the son wheel assembly and the one-way locking device separately is arranged on the driving gear. Due to the organic combination of the structure, balanced lifting adjustment and any height stopping of a bed net, a curtain and an overall support are achieved, a user can conveniently and flexibly use the bed net, assembly and disassembly difficulties in daily use of the bed net are lowered, the whole structure is simple and stable, and the application range is wide.

The invention belongs to the technical field of storage cabinets, and specifically relates to a corner cabinet accessory and a corner cabinet, including a pillar, a storage tray and a transmission assembly, and the storage tray can be manipulated around the pillar through the transmission assembly between the first position and the second position Movable, the transmission assembly includes a cantilever, a first guide rod and a second guide rod. The first end of the cantilever is fixedly connected to the pillar, and the second end extends to the bottom of the storage tray. The first guide rod is arranged on the outside of the cantilever, and one end can be The second end of the cantilever is rotatably connected around a first vertical swing axis, and the other end is rotatably connected with the storage tray around a first vertical hinge axis. The second guide rod is arranged on the cantilever. Inner side, one end of which is swingably connected to the cantilever around a second vertical swing axis separated from the pillar by a horizontal distance, and the other end is swingably connected to the storage tray around a second vertical hinge axis , The corner cabinet accessories can be assembled first and then assembled in the cabinet as a whole, thus reducing the difficulty of installation and disassembly.

The invention discloses an automatic disassembly and assembly connecting structure, which is used for fixedly connecting a first fixed part and a second fixed part. The automatic disassembly and assembly connecting structure comprises a fixed seat, an upper cover and a button, wherein the fixed seat is fixedly connected with the first fixed part; the upper cover is fixedly arranged above the fixed seat; the button penetrates into the upper cover. The automatic-disassembly and assembly connecting structure also comprises a leaf spring and a reset spring, wherein the leaf spring is fixedly connected with the upper cover, and the reset spring is arranged on the fixed seat and is abutted with the leaf spring. The invention also discloses a touch integrated machine. As the automatic disassembly and assembly connecting structure is fixed to the second fixed part by matching the button and the leaf spring, the second fixed part does not need to be assembled by adopting a bolt, and the disassembly and assembly difficulty of the second fixed part is reduced. The automatic disassembly and assembly structure for the leaf spring is applied to the touch integrated machine, and therefore, the disassembly and assembly difficulty of a face shell and a bottom frame of the touch integrated machine can be lowered.

The invention relates to a sintering machine head star wheel and material bin installing method. The sintering machine head star wheel and material bin installing method comprises the following stepsof determining construction positions of a temporary lifting beam and a lifting inverted chain; installing a material bin reversed lifting platform and an upper material bin in place; constructing thetemporarily lifting beam and the lifting inverted chain; constructing a sintering machine head skeleton and a temporary transportation track; enabling a head star wheel flexible transmission device to be transported and be in place in advance; horizontally transporting a sintering machine head star wheel; lifting the sintering machine head star wheel in place; lifting the head star wheel flexibletransmission device in place; installing a grate-layer material lower material bin in place; and installing a raw material feeding lower material bin in place. By means of the sintering machine headstar wheel and material bin installing method, the construction difficulty can be reduced, the construction period is shortened, and the construction safety is facilitated.

The invention discloses a tooling device and its application, and relates to the technical field of process equipment. A tooling device according to the present invention comprises: a frame on which at least one through hole is formed; and a plurality of legs fixed on the two end faces of the frame along the extending direction of the through hole, wherein all the legs on one end face The outriggers are connected to the main equipment; at least one base, the base is vertically installed on the end faces of the two outriggers on the side of the frame away from the main equipment; at least one ejector device is fixedly installed on the On the base, the telescopic rod of the ejecting device is aligned with the through hole, and the telescopic rod is allowed to be extended or shortened in the through hole. Through the detachable structure, the present invention solves the problem that the installation and disassembly of the integral tooling device is difficult and consumes a lot of time.
