Description

Technical Field

[0001] This utility model relates to a needle, specifically an auxiliary threading needle. Background Technology

[0002] Needles typically have a needle body, which is long and thin, with needle tips and thread holes at both ends.

[0003] Because of the small size of the needle, threading the needle has always been a difficult problem for users.

[0004] Existing technology, such as the Chinese utility model patent with publication number "CN202401256U" entitled "Easy-to-Thread Needle," discloses the following solution: "An easy-to-thread needle, comprising a needle body and a needle eye, with a groove on one side of the needle eye and an elastic baffle on one side of the groove." This solution achieves radial insertion of the thread through the elastic baffle. Although radial insertion of the thread is possible, it is difficult to position the thread at the elastic baffle and squeeze it towards the needle eye, thus causing inconvenience in use.

[0005] Another existing technology, such as the Chinese invention patent application with publication number "CN107164890A" entitled "An Easy-to-Thread Hand Sewing Needle," discloses the following solution: "An easy-to-thread hand sewing needle includes an integrally formed needle tip, needle shaft, and needle handle. The needle handle has a needle eye, which is an openable and closable structure. The openable and closable structure is formed by a U-shaped groove and an elastic arm provided on the side wall of the U-shaped groove. The U-shaped groove is located at the outer end of the needle handle and its opening faces outward. The elastic arm is received within the U-shaped groove. The outer surface of the elastic arm is smooth without sharp corners. The elastic arm is an inverted L-shaped structure with chamfered edges. The outer end of the bottom edge of the inverted L-shaped structure is fixed to the upper part of the side wall on one side of the U-shaped groove, and the side edge of the inverted L-shaped structure elastically abuts against the side wall on the opposite side of the U-shaped groove." This solution achieves axial insertion of the thread by setting an elastic arm at the opening of the U-shaped groove. However, the needle body is already relatively thin and has a small radial dimension, making it difficult to align the thread when inserting it axially. Utility Model Content

[0006] The purpose of this utility model is:

[0007] Design an auxiliary threading needle to improve the existing threading structure of needles. On the basis of the elastic structure, add a concave structure towards the inside of the needle body, and the concave structure extends along the axis of the needle body to achieve the alignment or positioning of the thread on a thinner needle body, so as to facilitate the thread being pressed into the threading hole.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] An auxiliary threading needle includes a needle body and a needle tip, the needle tip being located at one end of the needle body; it also includes a connecting portion, a bent portion, a concave portion, a hook portion, and a baffle; the connecting portion and the baffle are both located at the end of the needle body away from the needle tip; the hook portion, the concave portion, the bent portion, and the connecting portion are connected sequentially to form a curved elastic structure; the hook portion is pressed against the inner side of the baffle under the elastic force of the elastic structure; the top of the needle body, the connecting portion, the bent portion, the concave portion, the hook portion, and at least part of the baffle together form a threading hole; the concave portion is recessed relative to the baffle towards the central axis of the needle body.

[0010] Furthermore, the connecting part, the bending part, the concave part, and the top hook part are all integrally formed with the needle body; the baffle is integrally formed with the needle body.

[0011] Furthermore, the connecting part, bending part, concave part, top hook part, and baffle are all thinner than the needle body; and a gap is left between the connecting part and the baffle.

[0012] Furthermore, the connecting part, the bending part, and the concave part combine to form a U-shaped structure; a gap is left between the connecting part and the concave part.

[0013] Furthermore, the bending portion, the concave portion, and the top hook portion combine to form an S-shaped structure; a gap is left between the top hook portion and the top of the needle body.

[0014] Furthermore, the angle between the top hook and the central axis of the needle body is less than 90°; the top of the baffle is at a higher horizontal level than the end of the top hook.

[0015] The beneficial effects of this utility model are as follows:

[0016] An auxiliary threading needle improves upon the existing threading structure by incorporating an elastic structure at the end of the needle body away from the needle tip. Furthermore, an inwardly recessed structure is added to this elastic structure, extending along the axial direction of the needle body. This facilitates the insertion of the thread as it slides along the axial direction on a thinner needle, enabling thread alignment or positioning. This allows the thread to be easily pressed into the threading hole, completing the auxiliary threading process and simplifying user operation. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0024] refer to Figures 1 to 4 An auxiliary threading needle includes a needle body 1 and a needle tip 2, with the needle tip 2 located at one end of the needle body 1; the needle tip 2 is pointed and used to puncture the needle body 1.

[0025] The aforementioned auxiliary threading needle also includes a connecting part 4, a bending part 5, a concave part 6, a top hook part 7, and a baffle 8; wherein, the connecting part 4 and the baffle 8 are both located at the end of the needle body 1 away from the needle tip 2; the baffle 8 and the connecting part 4 are both integrally formed with the needle body 1.

[0026] The top hook portion 7, the concave portion 6, the bending portion 5, and the connecting portion 4 are connected in sequence to form a curved elastic structure; this elastic structure can be deformed by extrusion pressure during the insertion of the wire, and can be reset after the extrusion pressure disappears to prevent the wire from coming out.

[0027] The top hook 7 is pressed tightly against the inner side of the retaining wall 8 under the elastic force of the elastic structure, preventing the line from coming loose.

[0028] The top of the needle body 1, the connecting part 4, the bending part 5, the concave part 6, the top hook part 7, and at least part of the baffle 8 together form a threading hole 3; when the thread is located in the threading hole 3, the threading operation is completed.

[0029] The concave portion 6 is recessed relative to the baffle wall 8 and is closer to the central axis of the needle body 1; the concave portion 6 is used to align or position the thread during the threading process to facilitate the user's threading operation.

[0030] The connecting part 4, the bending part 5, the concave part 6, and the top hook part 7 are all integrally formed with the needle body 1 and are made of the same metal material as the needle body 1; the baffle 8 is integrally formed with the needle body 1 and the length of the baffle 8 is less than the length of the connecting part 4.

[0031] The connecting part 4, the bending part 5, the concave part 6, the top hook part 7, and the baffle 8 are all thinner than the needle body 1, which facilitates the threading operation; and there is a gap between the connecting part 4 and the baffle 8, which is used to accommodate the thread.

[0032] The connecting part 4, the bending part 5, and the concave part 6 are combined to form a U-shaped structure to prevent the wire from coming out; a gap is left between the connecting part 4 and the concave part 6 to accommodate the wire.

[0033] The bending part 5, the concave part 6, and the top hook part 7 are combined to form an S-shaped structure to prevent the thread from coming out and to facilitate the insertion of the thread; a gap is left between the top hook part 7 and the top of the needle body 1 to accommodate the thread.

[0034] The angle between the top hook 7 and the central axis of the needle body 1 is less than 90°, that is, the angle between the top hook 7 and the baffle 8 is less than 90°. This can guide the thread during the insertion of the top hook 7, which is beneficial for the thread to open the top hook 7 and prevent the thread from coming out. The top of the baffle 8 is at a higher horizontal height than the end of the top hook 7. The end of the baffle 8 can guide the thread during the insertion of the thread along the top hook 7 and work with the thread to open the top hook 7, so that the thread can be inserted into the thread hole 3.

[0035] The specific usage of this utility model is as follows:

[0036] When threading is required, straighten the thread and place it on the outer surface of the needle body 1 in a direction perpendicular to the needle body 1. Then slide the thread along the axis of the needle body 1 toward the baffle 8.

[0037] After the wire passes through the baffle 8, it will be embedded in the recessed part 6, that is, as Figure 3 The state shown. Since the concave portion 6 extends relatively long along the axial direction of the needle body 1, and the concave portion 6 is sufficiently recessed towards the inside of the needle body 1, it has enough space to accommodate the cross-section of the thread, thus facilitating the thread to enter the concave portion 6, which in turn facilitates the alignment or positioning of the thread.

[0038] Then, the thread is pulled towards the needle tip 2, and the thread squeezes the top hook 7. Under the inclined guiding action of the top hook 7 and the elastic deformation action of the above-mentioned elastic structure, the end of the top hook 7 disengages from the baffle 8, allowing the thread to pass through, thus realizing the thread entering the threading hole 3 and completing the threading action.

[0039] After the threading action is completed, the thread is blocked in the threading hole 3 by the structure composed of the connecting part 4, the bending part 5, the concave part 6, the top hook part 7 and the baffle 8. Under the elastic action of the elastic structure, the top hook part 7 presses against the baffle 8 again to prevent the thread from coming out.

[0040] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
