Problems solved by technology

[0032] In the worst case, the presence of said lumen completely weakens the performance of the column to ensure the anchorage of the corresponding weight, because the self-tapping screw engaged inside it cannot achieve the desired torque and loses its thread

Embodiment Construction

[0052] reference image 3 , Figure 3A as well as Figure 3B , The new system for anchoring the physical counterweight to the outer position on the plastic molded tub used for washing machines is based on a set of cylindrical molds obtained from the same material of the two traditional parts of the tub and the same molding process. The existence of the bifurcated pin (40) is based, that is, the two traditional parts of the barrel, namely the traditional cylinder (1) and the corresponding front closing flange (2).

[0053] Each pin (40) is designed to be inserted from the bottom to the top of the hole (21a) of the counterweight (21). When the counterweight (21) is arranged relative to the outer wall of the barrel, the pin has a set of three regularly distributed Longitudinal notch (40a).

[0054] In particular, it should be noted that the hole (21a) of the weight (21) has a truncated cone shape facing the end of the lower cross section of the barrel center.

Abstract

The present invention relates to an anchoring system of counterweights for washers and washer / dryer combos based on the presence of a plurality of tubular divaricable pins (40, 41,42) on the external walls of the plastic moulded tubs(l) that, after being inserted into through holes (21a) obtained on the said counterweights, are designed to receive suitable divaricating inserts (40b, 41b, 42b) to prevent uncoupling from the holes.

Description

Technical field [0001] This patent application for industrial invention relates to an anchoring system for the counterweight of a washing machine and a washing / drying machine. Background technique [0002] The following brief description of the prior art will make the features and advantages of the present invention more obvious. [0003] Reference figure 1 , The current mode of washing machine and washing / drying machine is a plastic tub with a combined structure, which is formed by two separate parts (1, 2) designed to be fixed by a known type The device is securely coupled and fixed. [0004] The first part includes a large concave cylinder (1) which is closed at one end by a bottom wall (10) with a central hole and connected to the back with a cylindrical nozzle (11) The cylindrical nozzle (11) is designed to accurately receive a metal bearing seat with a substantially cylindrical shape. [0005] The second part includes a flange (2) with a large central opening (20a) designed to...
