Description

Roller mounting structure for vacuum cleaner

The present invention relates to a vacuum cleaner, and more particularly, a roller for a vacuum cleaner, which can arrange a roller having a rib between an upper cover and a lower cover to reduce interference of a cover generated during rotation and improve rotational performance. It relates to a mounting structure.

The vacuum cleaner sucks external dust or foreign substances by the powerful suction force generated by the driving of the motor built into the main body. The sucked dust or foreign substances are collected in the dust collecting bag mounted in the dust collecting chamber, and the clean air Through the outside. In addition, the vacuum cleaner can be divided into a canister type, which is easy to clean and move corners, and a brush or nozzle replacement, and an upright type, which is easy to clean and store a large space. have.

Fig. 1 is a side view showing a canister type vacuum cleaner in a double view, the construction of which includes a dust collecting chamber and a driving chamber partitioned by an inner partition, and the main body portion 2 is free to move by a wheel 1. And a multi-stage connection type extension pipe (6) having a detachable brush head (3) attached to one end and a handle (5) having a suction force control switch (4) mounted on the other end. It is connected to the extension pipe (6) to form an air passage, and consists of a corrugated pipe (7) configured to be detachable to the main body (2).

Accordingly, when the vacuum cleaner is used, external dust or other foreign substances are sucked through the brush head 3 by the powerful suction force generated by the rotation of the drive motor mounted in the drive chamber in the main body 2, and this dust and The foreign matter is collected in a normal dust bag (not shown) mounted interchangeably in the dust collecting chamber, and at the same time, only filtered air is discharged to the outside through the driving chamber.

In the case of cleaning a large place using a vacuum cleaner having such a configuration, the wheel 1 attached to the main body 2 can be easily moved by rotating, and the brush head 3 is equipped with a roller that facilitates the movement. Bar, the mounting structure of a conventional vacuum cleaner roller with reference to the accompanying Figure 2 to help understand the present invention will be described.

FIG. 2 is a cross-sectional view showing a conventional roller mounting structure for a vacuum cleaner, and includes a rotation support part into which a through hole 9a of a roller 9 is fitted into a body 8 having an insertion hole 8b and a locking end 8c. 8a is formed, and the cover 9 is formed with an elastic lug 10a which is inserted into the insertion hole 8b formed in the body 8 and engaged with the locking end 8c. At the time of assembly, the through hole 9a of the roller 9 is fitted on the pivot support 8a of the body 8, and then the elastic lug 10a of the cover 9 is inserted into the insertion hole 8b of the body 8. Insert it in At this time, the end of the elastic lug 10a is extended at the moment of engaging with the engaging end 8c of the body 8 by its elastic force, thereby preventing the separation of the roller 9.

In the conventional vacuum cleaner roller mounting structure having such a configuration, when the roller 9 rotates, the elastic lug 10a formed on the cover 10 is prematurely worn by frictional contact with the locking end 8c of the body 8, There exists a problem that the rotational performance of the roller 9 falls.

The present invention devised to solve such a problem is to provide a roller mounting structure for a vacuum cleaner that can increase the rotational performance of the roller, prevent wear and extend the life by supporting the roller so as not to interfere. have.

The object of the present invention described above is that a plurality of rib support pieces are attached to the center, and when viewed from the rib support piece, the first flange and the second pivot support part having a first pivot support part arranged to face left and right An upper cover composed of a third cover and a fourth flange having a lower cover composed of a second flange having a third cover and a third and fourth pivot supporting portions respectively disposed up and down facing the first and second pivotal supports of the lower cover; And a roller having a rotating shaft extending along the longitudinal direction from the center of the rotating plate which is in contact with the rotating plate, and having a rib which is rotatably supported by the rib supporting piece of the lower cover. It is achieved by the roller mounting structure for the vacuum cleaner.

Hereinafter, with reference to the accompanying Figures 3 to 5 will be described in detail with respect to the roller mounting structure for a vacuum cleaner according to a preferred embodiment of the present invention.

Figure 3 is an exploded perspective view showing a vacuum cleaner roller mounting structure according to the present invention, Figure 4 is a cross-sectional view showing a disassembled roller mounting structure for a vacuum cleaner according to the present invention, Figure 5 (a) "< (c) is sectional drawing taken along the line AA "<CC in FIG. 4, respectively. First, referring to FIG. 3, a schematic configuration of the roller mounting structure according to the present invention is provided between the first flange 22 and the second flange 24, and the flanges 22 and 24. A lower cover 20 composed of a plurality of rib support pieces 26 and three first and second flanges 22 and 24 of the lower cover 20, respectively. It is rotatably supported by the upper cover 40 consisting of the third flange 42 and the fourth flange 44, and the lower cover 20 and the upper cover 40, which is disposed on the rotating shaft 34 It consists of the roller 30 in which the rib 36 for anti-separation was formed. In the present invention, the lower cover 20 serves to support the rollers in the same manner as the body 8 in the above-described conventional roller mounting structure, and the upper cover 40, like the conventional cover 10, has the upper rollers. Protects from

Looking at this in more detail with reference to Figure 4, a plurality of rib support piece 26 is attached to the center, when viewed relative to the rib support piece 26, the first pivot support portion 22a disposed to face left and right The lower cover 20 which consists of the 1st flange 22 which has () and the 2nd flange 24 which has the 2nd rotation support part 24a, and the 1st and 2nd rotation support parts 22a of the lower cover 20 And an upper cover 40 composed of third and fourth flanges 42 and 44 having third and fourth pivotal supports 42a and 44a, which are disposed to face up and down, respectively, 24a, and It is formed along the outer periphery of the pivot shaft 34 and the pivot shaft 34 extending in the longitudinal direction from the center of the rotating plate 32 in contact with the bottom, the rib support piece 26 of the lower cover 20 It consists of the roller 30 which has the rib 36 supported so that rotation is possible.

Therefore, the pivot shaft 34 of the rollers includes the first and second pivot supports 22a, 24a and the upper cover 40 formed on the first flange 22 and the second flange 24 of the lower cover 20. Is rotatably supported by the third and fourth pivotal support portions 42a, 44a formed on the third flange 42 and the fourth flange 44 of FIG.

Here, the hole 34a was formed in the inside of the rotational shaft 34 which comprises the roller 30, and rigidity was increased. In addition, the rib 36 formed in the roller 30 in the assembled state is a mounting space portion provided by the first flange 22 and the third flange 42 and the second flange 24 and the fourth flange 44. It is fitted to (28) and (48) to prevent separation, and is supported to be rotatable by the rib support piece 26 of the lower cover 20. The third flange 42 and the fourth flange 44 of the upper cover 40 are coupled by the fixing piece 46.

Next, as shown in FIGS. 5A to 5C, the rib support piece 26 attached between the first flange 22 and the second flange 24 of the lower cover 20 is In order to be able to support the circular rib 36, the end portion was manufactured in the same circular shape as the outer circumferential surface of the rib 36.

In addition, in order to prevent the upper cover 40 and the lower cover 20 from interfering when the roller 30 rotates, the first pivot support part formed on the first flange 22 of the lower cover 20 ( 22a) is formed longer than the third pivot support portion 42a formed on the third flange 42 of the upper cover 40.
