Fixing and protecting device used when dust collector is transported

Abstract

The invention discloses a fixing and protecting device used when a dust collector is transported. The device comprises a supporting ring and a supporting base, the supporting ring supports the front portion of the dust collector, and the supporting base supports the rear portion of the dust collector. The supporting ring is of a ring structure and formed by axially connecting three layers of rings. The rings are connected through a plurality of supporting columns which are arranged around the rings at equal intervals. The diameters of the rings are gradually reduced from bottom to top. The end face of the uppermost layer of supporting ring is in butt joint with the bottom face of the front portion of the dust collector. The supporting base is a transverse columnar body, and the upper surface of the supporting base is an arc face and is in butt joint with the arc face at the corner between the lower surface of the rear portion of the dust collector and the rear wall of the dust collector. The supporting ring is arranged to be of a multi-layer structure so that the supporting ring can keep elastic axial deformation and can reliably support the bottom of the dust collector all the time, and damage caused when the front portion of the dust collector moves downwards due to transportation is avoided. Fixing columns arranged for the supporting rings can effectively constrain backward transverse moving of the dust collector during vibration, damage caused when the dust collector transversely moves backwards is avoided, and safety of the dust collector in the transportation process is guaranteed.

Description

technical field [0001] The invention relates to an auxiliary device of a vacuum cleaner, in particular to a fixing protection device for a vacuum cleaner during transportation. Background technique [0002] The existing vacuum cleaner needs to be provided with a foamed protective pad in the packaging box before transportation. The shape of the protective pad matches the shape of the bottom of the vacuum cleaner. When the packaging box vibrates, the protective pad forms a buffer protection for the vacuum cleaner. [0003] The disadvantage of the prior art is that the traveling wheels of the vacuum cleaner are usually used as a fulcrum in the packing box, and the traveling wheels are usually arranged at the rear of the vacuum cleaner. When the vacuum cleaner vibrates during transportation, due to the leverage generated by the position of the traveling wheels, The stress on the front of the vacuum cleaner mainly comes from its lower part, while the stress on the rear mainly com...

[0003] The disadvantage of the prior art is that the traveling wheels of the vacuum cleaner are usually used as a fulcrum in the packing box, and the traveling wheels are usually arranged at the rear of the vacuum cleaner. When the vacuum cleaner vibrates during transportation, due to the leverage generated by the position of the traveling wheels, The stress on the front of the vacuum cleaner mainly comes from its lower part, while the stress on the rear mainly comes from the lateral inertial force, and the protective pad made of foam material is brittle and easy to break, and cannot provide preset support for the vacuum cleaner after breaking Protect
