Description

Drum type washing machine balancing weight mounting structure

Technical Field

The invention belongs to the field of clothes cleaning equipment, and particularly relates to a mounting structure of a balancing weight of a drum washing machine.

Background

Common washing machine in the existing market, the balancing weight is generally all through self-tapping bolt direct mount to the pail. Because the bolt uses self tapping screw to fasten, skid easily after the dismouting many times, can cut the balancing weight erection column even because bolt self tapping fastening, produce the crackle easily on the balancing weight erection column, cause stress concentration to destroy the intensity of balancing weight erection column, lead to final balancing weight erection column to damage, whole pail is scrapped.

In view of the above, the present invention provides an installation structure of a counterweight block of a drum washing machine, which aims to solve the problem that in the prior art, a bolt of the counterweight block is easy to slip and a mounting column of the counterweight block is easy to damage, so that a washing barrel is scrapped.

Disclosure of Invention

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a drum type washing machine balancing weight mounting structure, includes pail, balancing weight erection column, elasticity mounting bracket, balancing weight, bolt, gasket. The washing barrel is provided with the counterweight block mounting column, and a clamping structure and positioning ribs are designed on the periphery of the mounting column; the elastic mounting rack can be clamped into the clamping structure on the mounting column through elastic deformation; the elastic mounting frame is provided with threads matched with the bolts; after the balancing weight is installed, the elastic mounting frame is extruded to deform; and finally, fixing the gasket, the balancing weight mounting column, the elastic mounting frame and the relative position of the balancing weight through the threaded fit of the bolt and the elastic mounting frame.

Among the above-mentioned technical scheme, as preferred, the balancing weight erection column is cylindrical structure. And the counterweight block is provided with a mounting hole site structure matched with the counterweight block mounting column. The elastic mounting frame is provided with a structure matched with the clamping position of the counterweight block mounting column, the counterweight block can be well matched with the counterweight block mounting column and the counterweight block after being pressed and deformed, and the elastic mounting frame can be clamped into the clamping position structure on the mounting column through elastic deformation.

Preferably, before and after the elastic mounting frame is elastically deformed, the counterweight mounting column positioning rib can limit the rotation of the elastic mounting frame.

Preferably, the elastic mounting frame is provided with an elastic deformation structure at the top, so that elastic deformation reaction force can be generated after the bolt is assembled and fixed, and a locking effect is achieved.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention. Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

As shown in fig. 1, 2, 3, 4, and 5, during assembly, the elastic mounting bracket (20) is first mounted on the matching position of the counterweight mounting column (10), at this time, the elastic mounting bracket (20) is not elastically deformed, and the positioning rib (112) on the counterweight mounting column (10) limits the axial rotation of the elastic mounting bracket (20).

Next, the balancing weight (30) is installed on the matching position of the balancing weight installation column (10), and at the moment, the balancing weight presses the elastic installation frame (20) to be elastically deformed and clamped into a clamping structure (111) of the balancing weight installation column.

Next, the bolt (40) penetrates through the gasket (50) and the balancing weight (30) to be assembled and fastened with the elastic mounting frame (20) through threads. At the moment, the elastic mounting frame (20), the counterweight block (30), the bolt (40) and the gasket (50) are fixed relative to the counterweight block mounting column (10), and the whole structure is assembled. Elasticity mounting bracket (20) rely on elastic deformation to connect balancing weight (30) and balancing weight erection column (10), can play the cushioning effect, when reducing the dehydration balancing weight (30) with produced impact force of the alternate motion between balancing weight erection column (10).

Fig. 6, fig. 7 show the elastic mounting frame (20), and the counterweight mounting column (10) are structures matched with another embodiment of the invention.
