Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 6: the utility model provides a collapsible bench fan that draws in, includes fan head 5, stand 1, locking structure 2, base 3, wherein fan head 5 rotates with stand 1 upper end to be connected, and locking structure includes stand cover 21, cover shell 22 and mounting 23, and stand cover 21 upper portion links to each other with stand 1, and stand cover 21 lower part rotates with base 3 to be connected, still opens draw in groove 31 on the base 3 and is used for holding folding stand 1 of drawing in, and mounting 23 cover is established on stand cover 21, and cover shell 22 overlaps on stand cover 21 and is located the mounting top, and cover shell 22 internal face is equipped with lug 221, the outer wall face of stand cover 21 corresponds the position and is equipped with "L" type groove, "L" type groove divide into vertical groove 211 and horizontal groove 212, and when the lug card goes into the horizontal groove 212 in "L" type groove, cover shell 22 will mounting 23 is consolidated on base 3.

The column sleeve 21 and the column 1 are fixed by the fastener. When the cover 22 locks the fixing piece 23 on the base 3, the bottom of the fastening piece 4 is spaced from the top of the cover 22.

The depths of the vertical groove 211 and the horizontal groove 212 of the L-shaped groove are equal to the thickness of the lug 222 of the sleeve 22, the width of the vertical groove 211 is equal to the length of the lug 222, and the width of the horizontal groove 212 is equal to the width of the lug 222.

The lower part of the upright sleeve 21 is provided with a rotating shaft 213, the base 3 is provided with two mounting holes corresponding to the rotating shaft 213, and two ends of the rotating shaft 213 are respectively inserted into the two mounting holes.

The side of the fan head 5 is provided with a fastener 51, the corresponding position of the side of the base 3 is provided with a fastener groove 32, when the desk fan is in a folded state, the upright post 1 is accommodated in the furling groove 31, the back of the fan head 5 is tightly attached to the top surface of the base 3, and the fastener 51 is tightly attached to the fastener groove 32.

The utility model discloses a theory of operation: when the desk fan is folded, the cover 22 is rotated to slide the protrusion 222 from the end of the horizontal slot 211 of the "L" shaped slot to the junction of the horizontal slot 211 and the vertical slot 212, and at this time, the cover 22 can not rotate in the same direction.
