A multifunctional foldable household crane

Abstract

The invention discloses a multifunctional foldable domestic crane. A motor support is fixed to the lower bottom face of an upper beam of a box-shaped machine frame. A lifting drive motor is installedon the motor support. A left lifting screw and a right lifting screw are connected to the left end and the right end of a lower beam of the box-shaped machine frame in a rotatable mode respectively and further extend to the left end and the right end of the upper beam in an upward mode. Lockable universal wheels are further installed at the bottom of the lower beam. The left side and the right side of the machine frame are connected with a left fixing frame and a right fixing frame in a rotatable mode correspondingly. The lifting drive motor drives the left lifting screw and the right liftingscrew to conduct screw drive on a jack mechanism to make ascending and descending motion along the two screws through a lifting transmission mechanism, and objects can be carried by matching the leftfixing frame and the right fixing frame as well as the lockable universal wheels. The rear side of the machine frame is further detachably connected with a folding chair. According to the multifunctional foldable domestic crane, semi-electrification control over home appliance carrying is realized, time and labor are saved, production cost is low, the dimensions of the left fixing frame and the right fixing frame are adjustable, the range of application is wide, the left fixing frame, the right fixing frame and the jack mechanism can be folded for storage, and storage space is reduced; and inaddition, the multifunctional foldable domestic crane is detachably connected with the folding chair, and the functions are diversified.

When home appliances or furniture are placed for a period of time, people often need to move them and clean them. The easy handling of these large and medium-sized furniture has always been a problem for consumers. Most of the existing handling methods rely on manual handling on small carts. Moving, time-consuming and labor-intensive, and may cause damage to furniture during manual handling

The patent No. CN108974813A is a household appliance handling device. It uses a lifting device to transport household appliances to the transport frame, and then uses a transport vehicle for transport. It is simple, convenient, stable and reliable, but the structure of the household crane is complex and requires multiple motors. Driven operation, high production cost, no fixing device, for household appliances with unstable bottom, it may cause dumping damage during transportation, in addition, the device has no other functions other than transportation, and the product flexibility is low
