Description

bobbin storage bar

The invention relates to a bobbin storage bar, especially a sewing machine bobbin storage bar that is easy to store and use, and can be connected together to expand capacity.

Although there are many types of modern sewing machines for household and various specialized industrial production applications, the basic principle has not changed. In these sewing machines, there is a needle that reciprocates up and down and carries the needle thread wound on the spool (Sewing Spool) through the sewing. The sewing object is interlocked with the bobbin thread carried by the rotary hook (shuttle shuttle) that rotates (swings) below the sewing object to shape the sewing object.

The bobbin thread is usually wound on a bobbin by a bobbin winding shaft attached to the sewing machine, or by a dedicated bobbin winder. Because the diameter of a general household or industrial bobbin is about 20~21mm, the height is about 10~11mm, and the body is quite small, the bobbin thread that can be carried is actually very limited. Simultaneously, in order to cooperate with sewing operation needs, often will use the bottom line of two or more colors. Therefore, in order to improve efficiency, before sewing, the bobbin winding shaft on the sewing machine is generally used to pre-wind the bottom threads of the same or different colors on multiple bobbins for backup, so that the bottom threads can be quickly replaced when they are used up.

Fig. 1 is for the convenience of accommodating bobbin and common a kind of customary storage box. The bobbin storage box 20 is generally made of transparent or translucent hard plastic into a rectangle, and the space inside the box is divided into a plurality of rectangular inner compartments 21 , and each inner compartment 21 accommodates one bobbin 30 .

Since the bobbin storage box 20 is made of general plastic, and the opening length and width of the rectangular inner grid 21 are respectively greater than the diameter and height of the bobbin 30 . Therefore, when the bobbin 30 is inserted into the inner grid 21, there will be a large gap between the bobbin 30 and the opening of the inner grid 21, so that the thread ends of the bottom thread 40 wound on the bobbin 30 can easily pass through the gap. loose. In addition, the known bobbin storage box 20 is not expandable, that is, the same two bobbin storage boxes 20 cannot be connected together for use.

This creation is made to solve the above-mentioned problems, and its purpose is to provide a bobbin storage bar, which makes the bobbin storage and access convenient and efficient, and can prevent the bottom thread on the bobbin from loosening.

Another purpose of this creation is to provide a bobbin storage bar, which allows more than two storage bars to be used in parallel to expand the capacity.

Specifically realize the bobbin storage bar of this creation, which is made of long strips including but not limited to thermoplastic elastomer (TPE), along the length direction of the storage bar is provided with a storage groove with a notch facing upwards, the depth of the storage groove Between the radius and the diameter of the bobbin to be accommodated, the width of the notch is smaller than the diameter of the bobbin. After the bobbin is inserted into the receiving groove from the notch, it is held by the top of the two slots defining the notch. Most of them are submerged in the storage tank, and part of them are exposed outside the storage tank.

In a preferred embodiment, the two corresponding long sides of the receiving strip are respectively provided with two tenon grooves and two latches, allowing more than two storage strips to be connected together by inserting the latches into the tenon grooves.

In a preferred embodiment, the section shape of the receiving groove is between a semicircle and a full circle, so that the part of the bobbin submerged in the receiving groove can fit with the groove wall of the receiving groove.

Compared with the general bobbin storage box, the effect of this creation is that it is made of thermoplastic elastomer, and the bobbin can be easily inserted into the position, so that the storage and access of the bobbin are convenient and efficient, and at the same time, it can avoid the bottom thread on the bobbin The thread is loose.

In addition, the bobbin storage bar is expandable, and more than two storage bars can be used in parallel through the cooperation of the tenon and the slot to increase the bobbin storage capacity.

As for the detailed technical content and other purposes and characteristics of this creation, it can be fully understood with reference to the description of the embodiments in conjunction with the accompanying drawings below.
