Description

Technical Field

[0001] This utility model relates to the field of knitting tools, and in particular to a knitting needle. Background Technology

[0002] Weaving is a handicraft or technique that combines threads, fibers, or other materials through interlacing, winding, and threading to create a specific shape, structure, or pattern. Common weaving methods are mainly divided into hand weaving and machine weaving. Hand weaving is not only a skill for making items, but it also carries rich cultural, emotional, and life significance. It is also an expression of creativity and individuality. Whether for practicality, art, or emotion, hand weaving plays an important role in people's lives.

[0003] To improve efficiency in the knitting process, a practical knitting needle is indispensable. Japanese Patent Publication No. JP2018512895 discloses a knitting needle having at least one needle tip (11) and a shaft (12), wherein knitting can be arranged in at least one area on the shaft (12). Further, a holding area (13) is provided, which is located near the needle tip (11) on the shaft (12) and has a circular cross-section. The knitting needle (10) itself tapers gradually along its length (15) from the shaft (12) to the needle tip (12). In this invention, the needle tip (11) itself is made circular and has a teardrop-shaped enlargement with a smaller diameter than the shaft (12), namely a droplet portion 20 attached to the tip of the needle tip (11).

[0004] However, the technical solutions proposed in the aforementioned patents do not include needle storage, which poses a safety hazard; the needles cannot be replaced to adapt to different knitting methods, and the thin grip can cause deformation between the hand and the contact surface during long-term knitting, leading to pain and harming the user's hand health. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the needle is not retractable and cannot be replaced, and therefore provides a knitting needle.

[0006] A knitting needle adopts the following technical solution:

[0007] A knitting needle includes a first housing, a second housing, and a third housing. The first housing contains a needle body. The second housing is a semi-open cylindrical body with an extension tube at the top. The bottom surface of the second housing is connected to the end face of the third housing. The first housing and the extension tube cooperate to connect with the second housing.

[0008] The second housing has a fixing structure inside, the fixing structure includes a chassis coaxially arranged with the second housing, the edge of the chassis is uniformly provided with a claw in the direction away from the bottom of the second housing, and the outer side of the claw is provided with a first groove;

[0009] A movable tube is slidably provided between the chassis and the inner wall of the second housing. A first protrusion that cooperates with the first groove is provided at one end of the movable tube near the claw. The claw has a first state and a second state. In the first state, the first protrusion of the movable tube is engaged with the first groove. In the second state, the movable tube is separated from the first groove.

[0010] By adopting the above technical solution, the claw can release or retract the needle body by opening and closing, thereby allowing the needle body to extend during the knitting process and retract and be locked by the claw when the knitting ends or is paused, thus preventing it from coming out. This achieves the extension and retraction of the needle head and avoids safety hazards during the knitting process.

[0011] Furthermore, the side of the movable tube includes two opposing first curved surfaces, the first curved surfaces having opposite outward convex directions, the first curved surfaces having a first external thread, the maximum distance between the two first curved surfaces being less than the diameter of the extension tube, and a first plane being provided between the first curved surfaces.

[0012] The opposing first plane and the first curved surface form a special-shaped tube, which can ensure that the displacement is only in the axial direction after installation.

[0013] Furthermore, the first housing has a hollow portion, which includes two connecting pieces arranged opposite each other. Each connecting piece includes a second curved surface disposed on the outside of the first housing and a second flat surface disposed on the inside of the first housing. The distance between the second flat surfaces is the same as the distance between the first flat surfaces, and the maximum distance between the second curved surfaces is the same as the distance between the second curved surfaces of the first curved surfaces. The connecting pieces together form the installation position of the movable tube, and the length of the hollow portion is less than the length of the movable tube.

[0014] The first plane of the movable tube mates with the second plane of the connecting piece, which limits the movable tube and ensures that the movable tube can only move in the axial direction. The first hollow part ensures that the first external thread can extend out of the hollow part so that the first external thread can mate with the external structure. The length of the hollow part is less than the length of the movable tube, which ensures that when the movable tube releases the chuck and contacts the bottom of the second housing, a part of the movable tube is still in the hollow part, so that it is limited by the connecting piece of the hollow part.

[0015] Furthermore, the hollowed-out portion is fitted with a driving ring, and the driving ring is provided with a first internal thread that mates with the first external thread.

[0016] The first internal thread engages with the external thread on the movable tube, allowing the drive ring to rotate freely without tending to move axially upwards with the hollowed-out part, but rather with the movable tube.

[0017] Furthermore, the drive ring is provided with a plurality of second protrusions, and the edge of the hollow portion is provided with a plurality of second grooves that engage with the second protrusions.

[0018] The second protrusion, in conjunction with the second groove, can lock the drive ring to a certain extent, preventing the drive ring and the hollowed-out part from rotating relative to each other during the weaving process.

[0019] Furthermore, the first housing has an opening at one end away from the second housing, a third groove is provided inside the first housing near the opening, a gripping part is provided on the outside of the first housing, and the side of the first housing away from the gripping part has a tendency to converge in diameter.

[0020] The outer surface of the first shell conforms to the curve of the palm for easy gripping; the side of the first shell away from the gripping part has a tapering diameter that is aesthetically pleasing and in line with aesthetic standards.

[0021] Furthermore, the needle body includes a base and a needle bar, the top surface of the base is connected to the needle bar, the side of the base is provided with a locking slot that cooperates with the locking claw, and the connection between the base and the needle bar is provided with a third protrusion that cooperates with the third groove.

[0022] The third groove and the third protrusion can fix the extended needle bar when it is necessary to extend it, so that it can play a knitting role.

[0023] Furthermore, the extension tube is provided with a second external thread, and the bottom of the first housing is provided with a second internal thread that mates with the second external thread.

[0024] It facilitates the disassembly of the first housing and the second housing.

[0025] Furthermore, the third housing has a cavity inside, and a movable plate is provided on the third housing.

[0026] The third housing can accommodate needles of different sizes.

[0027] In summary, this application contains at least one of the following beneficial effects:

[0028] 1. By extending and retracting the movable tube, the engagement state of the first groove and the second protrusion can be changed, which can facilitate locking and releasing of the chuck, thereby facilitating the locking and releasing of the needle body inside the first housing;

[0029] 2. The connecting piece of the hollow part on the first housing can limit the movable tube so that it can move on the axis. At the same time, the length of the hollow part is less than the length of the movable tube. When the chuck is in the released state, the movable tube is close to the bottom of the second housing. At this time, there is still a part of the movable tube located between the connecting pieces, and the connecting pieces still play a role in limiting the movable tube.

[0030] 3. The hollowed-out part allows the first external thread on the movable tube to extend out of the hollowed-out part and engage with the first internal thread of the drive ring, thus facilitating the displacement of the movable tube.

[0031] 4. The second groove of the hollow part cooperates with the second protrusion on the drive ring to avoid the tendency of the first shell and the drive ring to rotate relative to each other during the weaving process;

[0032] 5. The third housing can hold needles with different needle tips, making it easy to replace them to adapt to different knitting techniques;

[0033] 6. The grip part of the first part conforms to the curve of the palm, effectively reducing the accumulation of hand fatigue. Attached Figure Description
