Description

Technical Field

[0001] This utility model belongs to the field of daily necessities and relates to a multi-point foldable duster. Background Technology

[0002] A duster is a tool used to remove dust, hair, and other tiny particles deposited on surfaces. It is commonly used for home cleaning, car cleaning, and is particularly suitable for cleaning hard-to-reach or difficult-to-wipe areas such as bookshelves, furniture tops, and wall decorations. However, existing dusters have a fixed structure and cannot flexibly adjust the size of the duster or the angle between the duster and the handle to suit the space available for dusting. Therefore, their use is somewhat limited, and their flexibility and convenience are lacking.

[0003] Therefore, this utility model provides a multi-point foldable duster to solve the above problems. Utility Model Content

Detailed Implementation

[0016] Example 1

[0017] like Figures 1 to 4As shown, the multi-point foldable duster of this utility model adopts the following technical solution: It includes a duster fixing plate 1, which comprises a left fixing plate 11. A bushing 111 is provided at the right end of the left fixing plate 11, and a screw 112 is fitted inside the bushing 111. A nut 113 is screwed onto the upper end of the screw 112. The right end of the left fixing plate 11 is hinged to the left end of the right fixing plate 12. A first fixing lug 121 is fixedly connected to the middle of the left rear sidewall of the right fixing plate 12. Several limiting grooves 122 are circumferentially arranged on the inner edge of the central hole of the first fixing lug 121. The upper and lower sides of the left front sidewall of the right fixing plate 12 are respectively fixed with second fixing ears 123. Decorative covers 124 are inserted into the upper and lower end inlets of the second fixing ears 123 respectively. A connecting assembly 2 is rotatably inserted into the central hole of the first fixing ear 121. The connecting assembly 2 includes a rotating shaft 21 fitted into the central hole of the first fixing ear 121. A spring fixing cover 22 is screwed onto the upper end of the rotating shaft 21. A connecting shaft cap 23 is fixed to the lower end of the rotating shaft 21. Symmetrical openings matching the limiting grooves 122 are formed on the left and right sides of the lower half of the rotating shaft 21. A limiting protrusion 24 is provided, and a spring 25 is mounted on the upper rotating shaft of the limiting protrusion 24. The upper end of the spring 25 is fixedly inserted into the lower part of the spring fixing cover 22. The outer periphery of the spring fixing cover 22 and the shaft cap 23 are respectively fitted together with the upper and lower ends of the T-shaped connector 26. The upper and lower ends of the T-shaped connector 26 have symmetrical countersunk holes 261, and an opening is formed between the upper and lower countersunk holes 261. A notch 262 is formed in the middle of the front side wall of the T-shaped connector 26, and an insertion hole 263 is formed at the rear end of the T-shaped connector 26. The two inner side walls of the upper countersunk hole 261 are symmetrically formed. The first insert 264 has two symmetrically arranged second inserts 265 on the front and rear inner walls of the lower countersunk hole 261. The first rectangular notches 221 are opened on the left and right sides of the spring fixing cover 22 directly opposite the first insert 264. The second rectangular notches 231 are symmetrically opened on the front and rear sides of the shaft cap 23 directly opposite the second insert 265. The center opening at the upper end of the lower countersunk hole 261 is symmetrically opened on the left and right sides of the limiting protrusion 24. The rear end of the T-shaped connector 26 is inserted into the connecting rod 3 through the insertion hole 263. The rear end of the connecting rod 3 is fitted with a handle 4.

[0018] The working principle of this utility model is as follows: When in use, the duster bristle sleeve is fitted onto the left fixing plate 11 and the right fixing plate 12. To reduce the length of the duster fixing plate 1, the left fixing plate 11 can be bent to the right and placed close to the front of the right fixing plate 12. Simultaneously, to change the angle between the connecting rod 3 and the duster fixing plate 1 according to cleaning needs, the spring fixing cover 22 inside the countersunk hole 261 at the upper end of the T-shaped connector 26 can be pressed downwards with a finger. The spring fixing cover 22 causes the rotating shaft 21 to move downwards, causing the limiting protrusions 24 on both sides of the rotating shaft 21 to engage with the first fixing ear 121 on the rear side of the right fixing plate 12. After the limiting groove 122 is separated, when the limiting protrusions 24 on both sides of the rotating shaft 21 are inserted into the limiting notch 266 at the upper end of the countersunk hole 261 at the lower end of the T-shaped connector 26, the right fixing plate 12 can be rotated clockwise or counterclockwise as needed to make it hover between the connecting rod 3 at different angles. Then, the spring fixing cover 22 is released. Under the action of the spring 25, the spring fixing cover 22 moves upward with the rotating shaft 21 and the shaft cap 23, so that the limiting protrusions 24 on both sides of the rotating shaft 21 are re-inserted into the limiting groove 122 in the first fixing ear 121, thereby fixing the connecting rod 3 and the right fixing plate 12 at each angle.
