Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The present utility model will be further described in detail below with reference to the drawings and detailed description for the purpose of enabling those skilled in the art to better understand the aspects of the present utility model.

It should be noted that, in the present embodiment, the orientation or positional relationship indicated by "upper", "lower", "front", "rear", etc. is based on the orientation or positional relationship shown in the drawings, and is merely for convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element to be referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," "third," "fourth," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

As shown in fig. 3 and fig. 4, in this embodiment, a button bottom piece is provided, where the button bottom piece includes an upper copper sheet 1 and a flute 7, an upper copper ring 3 is clamped on the upper copper sheet 1, a central hole for extending into the flute 7 is provided in the middle of the upper copper ring 3, and it should be noted that the side edge of the upper copper sheet 1 has a length, and the side edge of the upper copper sheet 1 can wrap the side edge of the upper copper ring 3, so as to implement clamping connection of the upper copper sheet 1; in addition, as shown in fig. 3 of the specification, the side edge of the upper copper ring 3 also has a certain length, but the length is obviously smaller than the length of the side edge of the upper copper sheet 1, but in order to enhance the stability of the upper copper ring 3 in the upper copper sheet 1, the side edge of the upper copper ring 3 can be abutted against the end face of the upper copper sheet 1, so that the movable space of the upper copper ring 3 in the upper copper sheet 1 is reduced, and the stability of the two settings is enhanced.

In other words, the side edge of the upper copper ring 3 can be provided with a bending part, and the side edge of the upper copper sheet 1 can wrap the bending part and is subjected to limit clamping, so that the upper copper sheet 1 and the upper copper ring 3 are stably connected.

In addition, unlike the traditional bottom piece, the middle part of the upper copper sheet 1 of the utility model is bent towards the central hole to form a bulge 9, the position of the bulge 9 corresponds to the position of the central hole, after the straight flute 7 stretches into the central hole, the straight flute 7 is always propped against the bulge 9 and generates extrusion force along with continuous stretching, the extrusion force forces the end part of the straight flute 7 to turn up, and the turned straight flute 7 can be clamped between the upper copper sheet 1 and the upper copper ring 3, so that the straight flute 7 and the bulge 9 are directly assembled.

It should be noted that the lower portion of the flute 7 is replaced by a bent form instead of the traditional lower copper sheet 5, and the flute 7 corresponding to the bent flute 7 can be parallel to the end face of the upper copper ring 3, and the flute 7 and the upper copper ring 3 can clamp the fabric 8 together.

In summary, the button bottom piece provided by the utility model eliminates the zinc alloy piece 2 and the lower copper piece 5, is integrally formed with the lower copper piece 5 through the straight flute 7, and is directly assembled with the straight flute 7 by utilizing the bulge 9 on the upper copper piece 1, so that the button bottom piece is lighter, thinner and more attractive, the cost and the assembling difficulty are effectively reduced, and the button bottom piece is more competitive in the market.

In addition, since the conventional lower copper sheet 5 is eliminated, the flute 7 needs to be directly connected with the lower copper ring 4, and in this embodiment, the periphery of the bottom of the flute 7 is clamped with the lower copper ring 4, so as to ensure the connection stability of the flute 7 and the lower copper ring 4.

Specifically, a right-angle bending part is arranged at the bottom of the flute 7, and similar to the bending part of the upper copper ring 3, the right-angle bending part needs to be embedded and clamped in the lower copper ring 4; of course, the right angle bend may be selected in a variety of ways, including but not limited to a right angle configuration, which will not be described in detail herein, to ensure that the flute 7 is stably connected to the lower copper ring 4.

Of course, in order to increase the fixing effect of the bottom piece, a copper ring 6 may be disposed between the right-angle bending portion and the lower copper ring 4, and the specific arrangement and requirement of the copper ring 6 are not repeated herein, and refer to the prior art specifically.

In addition, in order not to affect the use effect of the fabric 8 between the upper copper ring 3 and the flute 7, in this embodiment, the upper copper sheet 1 faces the end face of the fabric 8, protruding the side edge of the upper copper sheet 1; the end face of the part flute 7 with parallel end faces of the upper copper ring 3 protrudes out of the side edge of the lower copper ring 4. That is, when the fabric 8 is located between the upper copper ring 3 and the flute 7, two sides of the fabric are in contact with the upper copper ring 3 and the flute 7, and are not in contact with the upper copper sheet 1 or the lower copper ring 4, so that unnecessary friction on the fabric 8 is reduced, and the service life of the fabric 8 is protected and prolonged.

It is worth noting that, in order to enable the flute 7 to be uniformly turned over in its circumferential direction, in this embodiment, the protuberance 9 is provided as a conical protuberance, the axis of which is coaxial with the flute 7; in the contact process of the flute 7 and the conical bulge, the circumferential direction of the end part of the flute 7 can simultaneously support against the side wall of the conical bulge, so that the flute 7 can be uniformly turned. Of course, there may be various specific arrangement modes of the protrusions, such as a circular truncated cone, etc., which are not described in detail herein, so as to ensure that the technical effects of the present utility model can be achieved, and all fall within the protection scope of the present utility model.

The conical bulge is formed by stamping and is integrally formed with the upper copper sheet 1; the flute 7 may be of any other type of structure in the prior art, and is not limited herein.

It should be noted that in this specification relational terms such as first and second are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.

The principles and embodiments of the present utility model have been described herein with reference to specific examples, the description of which is intended only to facilitate an understanding of the method of the present utility model and its core ideas. It should be noted that it will be apparent to those skilled in the art that various modifications and adaptations of the utility model can be made without departing from the principles of the utility model and these modifications and adaptations are intended to be within the scope of the utility model as defined in the following claims.
