Abstract

[Problem] To provide a connecting fastener and a fan equipped with a connecting fastener. [Solution] The connecting fastener consists of a rotating body structure 10 and a movable structure 20. The movable structure has a rotating positioning groove 21 into which the rotating body structure is inserted and made rotatable, and an insertion groove 22 that enters from the radial direction. The rotating body structure is provided with an annular projection 11 coaxially, and a locking portion 23 is provided on the rotating positioning groove side to prevent the annular projection from coming out in the axial direction. Furthermore, a first positioning steel ball 30 is formed on one of the mounting surfaces, a first positioning recess is formed on the other, and a second positioning steel ball 50 is provided at an eccentric position, enabling stable positioning in multiple stages. This suppresses wear and maintains rotational resistance over a long period of time, and facilitates attachment/detachment and angle adjustment of the fan body and clip. Conventional clip-type fans have problems such as the rotating part being prone to wear, the angle holding force decreasing with long-term use, and the inability to stably fix at the desired angle. In addition, there was a problem that attachment/detachment of the fan body and clip was not easy, limiting the usage scenarios. [Selection Diagram] Figure 1

Description

This invention belongs to the technical field relating to the shape, structure, and combination of articles, and more particularly to a connecting fastener structure for detachably attaching to equipment such as electric fans. In recent years, parasols have become widely used as a means of blocking ultraviolet rays and direct sunlight in environments with strong sunlight and high temperatures. However, ordinary parasols do not have temperature regulation functions, which can make them uncomfortable for users walking outdoors. Therefore, a technology has been proposed to attach a small fan to a parasol in order to lower the perceived temperature when using it. Generally, a structure is adopted in which the fan is integrated into the frame of the parasol, and although this is effective in reducing stuffiness when using the parasol, there is a problem in that the fan and the parasol are integrated and cannot be used separately. Furthermore, a structure in which the fan and parasol can be separated is also known. For example, the fan is attached to the umbrella handle with a detachable clip, and the direction of the wind is changed by adjusting the angle of the clip. However, in this type of structure, the rotational positioning between the fan body and the clip relies mainly on frictional resistance, so wear progresses with long-term use, making it difficult to maintain appropriate rotational resistance and adjust the wind direction. This is a perspective view showing the overall configuration of the connecting fastener according to the present invention.This diagram shows the structure of the first end of the rotating body member.Figure 2 is a structural diagram of the rotating body member viewed from a different angle.This figure shows the structure of a fan body equipped with the connecting fastener of the present invention.This figure shows the overall configuration of a fan equipped with the connecting fastener of the present invention.This is a cross-sectional view along line A-A in Figure 5.Figure 6 is an enlarged view of the partial structure shown.

The connecting fastener according to this invention and the fan equipped therewith are widely applicable industrially as follows. The connecting fastener of this invention has a simple structure, excellent ease of assembly and attachment/detachment, and maintains a stable positioning function over a long period of time while reducing wear on the rotating parts. Therefore, it can be widely applied as an angle adjustment structure or movable connecting part in a variety of products such as small home appliances, portable fans, clip-on fans, and umbrella accessories. In particular, applying the connecting fastener of this invention to portable fans and clip-on fans makes it easier to fix them to umbrella ribs and handles, and to attach them to bags, clothing, furniture, etc., allowing them to be adapted to a variety of usage scenarios. Furthermore, since rotational resistance is stably maintained even after repeated use over a long period of time, it contributes to improved product reliability
