Lock nut for leg assembly of home appliance

Abstract

Disclosed are lock nuts (100) and (100a) for preventing a leg bolt (4) from loosening from a leg assembly supporting electric home appliances, and a wrench (500) for loosening or tightening the lock nuts (100) and (100a). The lock nuts (100) and (100a) includes a hub having a screw hole (111), a plurality of ribs extended in a radius direction from a circumferential surface of the hub, and having sides (125) and (125a) over which the wrench (500) or a finger is hooked, and supplementary member (130) provided allowing the wrench or finger to access form the radius direction of the hub to the sides (125) and (125a), and coupling the ribs (120). The wrench (500) includes a long grip having at least one projection (550) and (560) on an outer circumferential surface thereof, and a box end (530) or an open end (520) provided at either of both ends thereof.

Description

technical field [0001] The present invention relates to a lock nut and a wrench for a home appliance foot assembly, and more particularly to a lock nut and a wrench for preventing the foot bolts from supporting a home appliance (such as a washing machine or clothes dryer) from the foot assembly. Background technique [0002] In general, a foot for a home appliance is provided at its lower portion for supporting the home appliance. When the stand is applied to a home appliance, the service life and reliable operation of the home appliance are greatly affected by the installation conditions, the stand usually includes a screw structure on each corner of the home appliance for easily controlling its height. exist figure 1 In , an example in which a common leg assembly having this screw structure is set to a household appliance is shown. In the following, reference will be made to figure 1 The foot assembly is described in more detail. [0003] The screw hole 2a is provided...

AI Technical Summary

Problems solved by technology

In the case of a lock nut 1, the shape of the lock nut 1 not only makes it difficult to grasp it by hand, but also makes it difficult to use such as image 3 It is also difficult to turn it with the wrench shown

[0006] Therefore, it is very difficult for the worker to rotate the lock nut 1 during the initial rotation (loosening) of the lock nut 1 that requires a large torque and the final rotation (tightening), resulting in a lack of tightening force that causes The possibility of the lock nut 1 loosening also creates a problem of inefficiency when installing the foot assembly or controlling the height of the foot assembly
