Background

Ornament or wear products such as article, for the taste consider, perhaps can set up propeller blade on it, be convenient for play, and current propeller blade is mostly fixed to be set up on wearing article or ornament through a axle, perhaps utilizes structures such as limit structure or nut to fix propeller blade on the axle again, and this axle adopts threaded connection or other connected modes to fix on ornament or wear the piece again, and the structure is comparatively complicated.

SUMMERY OF THE UTILITY MODEL

To the deficiency that prior art exists, the utility model aims to provide a take propeller blade's helmet.

In order to achieve the above purpose, the utility model provides a following technical scheme: a helmet with propeller blades comprises a helmet body, a fixed shaft and propeller blades, wherein the fixed shaft is integrally formed on the helmet body, and the propeller blades and the fixed shaft form axial limiting circumferential rotation.

The shaft upper end is equipped with the ring channel, the screw blade cover is established in this ring channel, and is spacing by the bottom of ring channel, the ring channel upper end is equipped with the locating part that is used for restricting propeller blade axial slip.

The limiting piece is an insertion part which is integrally formed at the upper end of the fixed shaft.

The inserting part comprises conical pieces symmetrically arranged at two ends of the fixed shaft, the bottom end of each conical piece is an annular groove, a gap is formed between the two conical pieces, and the two conical pieces can move oppositely when the outer surfaces of the propeller blade and the two conical pieces are in contact with each other, and when the propeller blade enters the annular groove, the bottom ends of the conical pieces are limited.

The propeller blade is made of plastic.

The propeller blade has at least two blades.

And an annular supporting piece is arranged at the contact position of the blade.

The height of the annular support member is less than or equal to the width of the annular groove.

The utility model has the advantages that: utilize integrative setting fixed axle on the helmet to through the screw rather than the rotatable setting of circumference, the spacing cooperation of axial, thereby make the screw rotatable for the fixed axle, the structure of integral type in addition, reduction cost that can be very big also can guarantee the reliability of fixing between fixed axle and the helmet simultaneously.

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 efforts belong to the protection scope of the present invention.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

In the present application, unless expressly stated or limited otherwise, the terms "connected" and "fixed" are to be construed broadly, e.g., "fixed" may be fixedly connected or detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In addition, descriptions in the present application as to "first", "second", and the like are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit to the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

The utility model provides a take propeller blade's helmet, it includes helmet 1, this helmet can be fixed to be set up on article or animal head such as doll, people young through the setting, in order to further ensure the fixed reliability of helmet, can set up the rope fastening for it is fixed, secondly the helmet also can be wearing article such as cap.

The fixed shaft 2 and the propeller blade 3 which forms axial spacing circumferential rotation with the fixed shaft are integrally formed on the helmet, namely the propeller blade is axially limited and cannot slide, and the propeller blade can rotate in the circumferential direction, so that the helmet has certain playability and interestingness.

The propeller blade is made of plastic. The propeller blade is provided with at least two blades, an annular support member 32 is arranged at the contact position of the blades, the blades 31 are arranged on the periphery of the annular support member in a circumferential equally-divided mode, and the center of the annular support member is arranged in a perforated mode.

The shaft upper end is equipped with ring channel 22, the screw blade cover is established in this ring channel 22, and is spacing by the bottom of ring channel, the ring channel upper end is equipped with the locating part that is used for restricting propeller blade axial slip, ring support piece's highly be less than or equal to the width of ring channel, ring support piece can overlap promptly and establish in the ring channel to for the cooperation of sliding of ring channel circumference.

The limiting piece is an insertion part which is integrally formed at the upper end of the fixed shaft.

The portion of inserting sets up conical member 21 at the fixed axle both ends including the symmetry, the bottom of conical member is the ring channel, and is equipped with space 23 between two conical members propeller blade makes two conical members move in opposite directions when two conical member's surface contact to when propeller blade gets into the ring channel, by the bottom of conical member is spacing, and the bottom diameter of conical member slightly is greater than annular support piece's fenestrate diameter promptly, makes annular support piece can be spacing by the conical member after getting into the ring channel through this conical member, avoids it to drop.

The examples should not be construed as limiting the present invention, but any modifications made based on the spirit of the present invention should be within the scope of the present invention.
