Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, and more specifically, to a threading device for a sewing machine. Background Technology

[0002] A sewing machine is a tool used to sew together textile fabrics.

[0003] Sewing machines are usually equipped with several thread holes to guide the thread. However, during the preparation of the needle and thread, some operators often need to spend a lot of time threading the thread. Some thread holes with a small inner diameter are inconvenient for operators who have difficulty threading the thread.

[0004] Therefore, a new solution is needed to supplement the existing sewing machine category. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a threading device for a sewing machine.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a threading device for a sewing machine, including a guide cover, a notch on the guide cover, a scissor clamp fixedly provided on the guide cover that can expand according to the size of the notch on the guide cover, a first opening and a second opening when the notch on the guide cover is closed, the second opening being smaller than the first opening, and a fixing frame fixedly provided on the guide cover.

[0007] The present invention is further configured such that: the scissor clamp has a clamping area and a control area, the end of the clamping area away from the control area is fixed to the guide cover, and when the control areas are close to each other, the clamping area pulls the guide cover and widens the gap.

[0008] The present invention is further configured such that: the fixing frame is configured as a positioning block and two clamping rods fixed on the positioning block, and the end of the clamping rod away from the positioning block can clamp the guide cover, thereby forming the fixing frame as a whole clamping and fixing the guide cover.

[0009] The present invention is further configured such that: the positioning block has a groove, the size of the groove is equal to the size of the second opening, and the positioning block also has a through groove that communicates with the groove.

[0010] The present invention is further configured such that: the guide cover is provided with a fitting groove for clamping rods.

[0011] The present invention is further configured such that: positioning plates are provided on the two clamping rods, and the positioning plates clamp the two clamping rods.

[0012] The present invention is further configured such that the guide cover, positioning block, clamping rod and positioning piece are all made of TPU plastic material.

[0013] The present invention is further configured such that a magnetic sticker is bonded to the clamp rod.

[0014] In summary, this utility model has the following beneficial effects: the threading device, through its funnel-shaped guide cover, facilitates the guidance of the thread end, improving the success rate of threading. At the same time, the guide cover is equipped with positioning blocks and other components to assist in threading. Before threading, the user can set the guide cover or the threading device as a whole, so that the left hand holds the threading device and the right hand passes the thread end through the threading device and through the threading hole on the sewing machine or needle, thus achieving the purpose of threading.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] A threading device for a sewing machine, such as Figures 1-3As shown, the device includes a guide cover 1 with a notch 2. A scissor clamp 3 is fixedly mounted on the guide cover 1, capable of expanding to fit the size of the notch 2. When the notch 2 is closed, a first opening 4 and a second opening 5 are formed. The second opening 5 is smaller than the first opening 4. A fixing bracket is fixedly mounted on the guide cover 1. The guide cover 1 has a structure similar to a funnel. When aligned with the thread hole of the sewing machine at the second opening 5, it guides the thread end through the first opening 4, the inner wall of the guide cover 1, towards the second opening 5, and out through the second opening 5. The scissor clamp 3 has a clamping area 6 and a control area 7. The end of the holding area 6 away from the control area 7 is fixed to the guide cover 1. When the control areas 7 are close to each other, the holding area 6 pulls the guide cover 1 and widens the notch 2. The scissor clip 3 is set for the user to operate. In the initial state, the notch 2 of the guide groove is closed. The user can press the separated control areas 7 to make the holding area 6 open outward and drive the guide cover 1 to deform. At this time, the notch 2 of the guide cover 1 will become larger. Thus, after the thread is passed through one of the thread holes of the sewing machine, the user can open the notch 2 to let the thread pass through the notch 2, and the guide cover 1 can be removed.

[0019] The fixing frame consists of a positioning block 8 and two clamping rods 9 fixed on the positioning block 8. The end of the clamping rod 9 away from the positioning block 8 can clamp the guide cover 1, forming a clamping and fixing of the guide cover 1 by the fixing frame as a whole. The positioning block 8 has a groove 10, the size of which is equal to the size of the second opening 5. The positioning block 8 also has a through groove 11 that communicates with the groove 10. The positioning block 8 and the clamping rods 9 are used to position the guide cover 1 for the needle through which the thread passes. Through the inner arc surface formed on the surface of the positioning block 8, the user can make the second opening 5 of the guide cover 1 directly aligned with the needle through which the thread passes. The thread can pass through the second opening 5 and the groove 10 on the positioning block 8 to form the thread hole on the needle. Similarly, after the thread is threaded, the user can remove the guide cover 1 by using the scissors clip 3. The through groove 11 on the positioning block 8 allows the user to remove the thread directly without having to operate the positioning block 8. The guide cover 1 is provided with a fitting groove 12 for the clamping rod 9 to hold. The clamping rod 9 forms a mutual fixation between the positioning block 8 and the guide cover 1. It is embedded in the fitting groove 12 to avoid the guide cover 1 and the clamping rod 9 from slipping against each other.

[0020] Positioning plates 13 are provided on the two clamping rods 9. The positioning plates 13 clamp the two clamping rods 9. Therefore, the positioning plates 13 and the clamping rods 9 are detachably connected. They are used to position the height of the needle and the needle hole when the needle needs to be threaded. This allows the second opening 5, the groove 10 and the thread hole on the needle to be interconnected when the user puts the needle against the positioning plate 13. The guide cover 1, the positioning block 8, the clamping rods 9 and the positioning plate 13 are all made of TPU plastic material. TPU plastic material has good elasticity and can quickly return to its original shape after deformation at room temperature. A magnet 14 is glued to the clamping rods 9. The magnet 14 is set to form the attraction of the thread hole in other positions on the sewing machine. When there is contact with a component that can form a magnetic attraction effect, it can be temporarily fixed, which makes it convenient for the user to adjust the thread end.
