Description

Technical Field

[0001] This utility model relates to the field of crochet hook technology, and in particular to an electric crochet hook. Background Technology

[0002] A crochet hook is a tool used for knitting, typically for crocheting handicrafts such as knitting sweaters, scarves, and carpets. One end of the crochet hook is hook-shaped and used to grab the yarn and pull it through the completed knitting loop to gradually form the fabric. Crochet hooks are very common in various handicraft projects, and different sizes of crochet hooks can be selected according to the thickness of the yarn and the knitting needs.

[0003] With the popularization of hand knitting and weaving, crochet has become a popular recreational activity and handicraft skill. Traditional crochet relies entirely on manual labor, which can easily lead to long-term muscle fatigue. This is especially challenging for people with disabilities who have limited hand function. Because it requires a high degree of hand dexterity and strength, many people with disabilities cannot complete crochet tasks independently, which limits their participation in such activities. Currently, there is a need for a new type of assistive device that can effectively combine crochet with mechanical hand movements to provide a more precise, flexible, and efficient solution. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides an electric crochet hook that transforms manual operation into electric drive through a transmission mechanism, reducing the user's hand involvement and preventing muscle strain during prolonged operation, thus solving the problem of hand fatigue.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an electric crochet hook, including a crochet hook housing and a crochet hook body, wherein the front and rear ends of the crochet hook housing are respectively provided with detachable covers, the crochet hook housing is provided with an installation mechanism, and a transmission mechanism is fixedly installed in the crochet hook housing through the installation mechanism. The output end of the transmission mechanism is connected to the crochet hook body, and the transmission mechanism drives the crochet hook body to reciprocate and extend.

[0006] As a preferred technical solution of this utility model, the transmission mechanism includes a support frame installed on the inner wall of the hook housing, a drive motor fixedly installed on the support frame, a plug slot that is plugged into the output end of the drive motor, a transmission frame slidably connected to the inside of the hook housing, a rotating column with a plug slot on its outer side wall and connected to the transmission frame, a slot opened in the rotating column, a moving block with one end slidably connected in the slot, and a moving rod with the other end connected to the moving block, wherein the outer wall of the transmission frame is connected to the mounting mechanism.

[0007] As a preferred embodiment of this utility model, the output shaft of the drive motor is configured as a hexagonal prism, and the insertion slot is configured as a hexagonal prism that matches the output shaft.

[0008] As a preferred technical solution of this utility model, the slot is opened horizontally around the outer wall of the rotating column, and the width of the slot is set to be equal to the diameter of the moving block.

[0009] As a preferred embodiment of this utility model, the movable rod is slidably connected to the bottom end of the transmission frame, and the outer end of the movable rod is connected to the hook body.

[0010] As a preferred technical solution of this utility model, the installation mechanism includes a sliding groove on the inner wall of the hook housing, a slider that is slidably connected to the sliding groove and connected to the outer wall of the transmission frame, two sets of threaded grooves fixed on the bottom outer wall of the transmission frame, two sets of through holes on the bottom outer wall of the hook housing, and two sets of threaded rods that are threadedly connected to the threaded grooves through the through holes.

[0011] As a preferred embodiment of this utility model, the outer end of the groove extends to the outer end wall of the hook housing, and the slider is fixed at the middle position of the top of the transmission frame.

[0012] As a preferred technical solution of this utility model, the threaded grooves are symmetrically opened at both ends of the bottom of the transmission frame, and the two sets of through holes are opened corresponding to the two sets of threaded grooves.

[0013] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0014] 1. Reduce muscle fatigue: The use of traditional crochet hooks requires maintaining high dexterity and strength in the hands for a long time, which can easily cause muscle fatigue, especially for people with weak or tired hand functions. This electric crochet hook, through a transmission mechanism, transforms manual operation into electric drive, reducing the user's hand involvement and preventing muscle strain during long-term operation, thus solving the problem of hand fatigue.

[0015] 2. Enhancing the participation of people with disabilities: This electric crochet hook, through its automated transmission system, can effectively mechanize and refine the crochet action. For people with disabilities, this design greatly reduces the hand strength and dexterity required to participate in hand crochet, enabling them to complete crochet tasks independently, breaking through the high requirements of traditional crochet hooks on hand function.

Detailed Implementation

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0023] Example:

[0024] like Figure 1-5 As shown, an electric crochet hook includes a crochet hook housing 1 and a crochet hook body 2. The front and rear ends of the crochet hook housing 1 are respectively provided with detachable covers. The crochet hook housing 1 is provided with an installation mechanism 4. A transmission mechanism 3 is fixedly installed inside the crochet hook housing 1 through the installation mechanism 4. The output end of the transmission mechanism 3 is connected to the crochet hook body 2. The transmission mechanism 3 drives the crochet hook body 2 to reciprocate and extend.

[0025] The transmission mechanism 3 includes a support frame 32 mounted on the inner wall of the hook housing 1, a drive motor 31 fixedly mounted on the support frame 32, a plug slot 33 that is plugged into the output end of the drive motor 31, a transmission frame 34 slidably connected inside the hook housing 1, a rotating column 35 with a plug slot 33 on its outer side wall and connected to the transmission frame 34, a slot 36 opened in the rotating column 35, a moving block 37 slidably connected at one end in the slot 36, and a moving rod 38 connected at the other end to the moving block 37, wherein the outer wall of the transmission frame 34 is connected to the mounting mechanism 4;

[0026] An external switch is provided on the outer wall of the hook housing 1. The external switch is used to drive the drive motor 31 to work. When the drive motor 31 starts, it drives the output shaft to rotate. The output shaft drives the rotating column 35 to rotate on the transmission frame 34. The rotation of the rotating column 35 drives the slotted 36 to rotate synchronously. The slotted 36 then drives the moving block 37 connected to it to move. The moving block 37 drives the moving rod 38 connected to it to move synchronously. The moving rod 38 drives the hook body 2 connected to it to move synchronously. The rotation of the rotating column 35 drives the moving block 37 to move back and forth, thereby driving the hook body 2 to perform reciprocating extension and retraction motion inside the hook housing 1, achieving the effect of fully automatic knitting.

[0027] It is worth noting that the output shaft of the drive motor 31 is set in a hexagonal prism shape, and the insertion slot 33 is set in a hexagonal prism shape that matches the output shaft. The hexagonal prism structure provides a more secure connection and avoids the slippage or loosening that may occur with conventional circular insertion methods.

[0028] The slot 36 is horizontally and circumferentially opened on the outer wall of the rotating column 35. The width of the slot 36 is set to be equal to the diameter of the moving block 37, which ensures that the moving block 37 can maintain stable guidance and sliding during the rotation of the rotating column 35. The slot width is equal to the diameter of the moving block 37, which can ensure the accuracy of the movement, so that the moving block 37 can move smoothly in the rotating column and reduce unnecessary friction or jamming.

[0029] The movable rod 38 is slidably connected to the bottom end of the transmission frame 34. The outer end of the movable rod 38 is connected to the hook body 2. Through the sliding connection, the movable rod 38 can move freely on the transmission frame 34, and the connection between the outer end and the hook body 2 allows the hook body 2 to reciprocate and extend with the movement of the movable rod 37.

[0030] The mounting mechanism 4 includes a groove 41 on the inner wall of the hook housing 1, a slider 42 that is slidably connected to the groove 41 and connected to the outer wall of the transmission frame 34, two sets of threaded grooves 43 fixed on the bottom outer wall of the transmission frame 34, two sets of through holes 45 on the bottom outer wall of the hook housing 1, and two sets of threaded rods 44 that are threadedly connected to the through holes 45 and the threaded grooves 43.

[0031] Workers can disassemble the hook body 2 and the moving rod 38 separately. Simply unscrew the front cover at the left end of the hook housing 1, and then disassemble the hook body 2 and the moving rod 38. At the same time, the two sets of threaded rods 44 at the lower end of the hook housing 1 can be loosened so that the threaded rods 44 and the threaded grooves 43 are engaged and loosened downwards until the two sets of threaded rods 44 are completely removed from the through hole 45, releasing the fixation on the transmission frame 34. At this time, the moving rod 38 can be pulled outwards, causing the moving rod 38 to drive the transmission frame 34 to move outwards. The transmission frame 34 slides outwards in the slide groove 41 through the slider 42. At this time, the insertion groove 33 at the right end of the rotating column 35 separates from the output shaft of the drive motor 31. Finally, the entire transmission frame 34 can be disassembled for inspection or replacement. It is worth noting that the rotating column 35, the moving block 37, and the moving rod 38 can all be disassembled from the transmission frame 34.

[0032] It is worth noting that the outer end of the slide groove 41 extends to the outer end wall of the hook housing 1, and the slider 42 is fixed at the middle position of the top of the transmission frame 34, so that the transmission frame 34 can be easily pulled out from the outside for maintenance or replacement.

[0033] The threaded grooves 43 are symmetrically opened at both ends of the bottom of the transmission frame 34, and two sets of through holes 45 are opened corresponding to the two sets of threaded grooves 43, which ensures that the threaded rod 44 can evenly fix the transmission frame 34 and enhance the stability of the structure.

[0034] The specific operating conditions of this device are as follows:

[0035] 1. Fixing the device (static preparation): Clamp the electric crochet hook body (crab hook housing 1) to the edge of a stable workbench or a flat table using the mounting mechanism 4 at its bottom.

[0036] 2. Structural state: The hook housing 1 is firmly fixed, and the internal transmission mechanism 3 (including drive motor 31, support frame 32, transmission frame 34, rotating column 35, etc.) and mounting mechanism 4 (slide groove 41, slider 42, threaded groove 43, threaded rod 44) ​​are in a static standby state. The threaded rod 44 is fully screwed into the threaded groove 43, which firmly fixes the transmission frame 34 inside the housing. The slider 42 is stuck in the slide groove 41 to ensure that the frame can only slide in a specific direction. The hook body 2 is completely retracted into the hook housing 1.

[0037] 3. Install the compatible crochet hook (static preparation): Unscrew the removable cover at the front end of the crochet hook housing 1, select the crochet hook body 2 of the required size, insert its end into and firmly connect it to the outer end of the moving rod 38 of the transmission mechanism 3, and tighten the front cover after confirming that the connection is secure.

[0038] 4. Structural state: The hook body 2 and the moving rod 38 are rigidly connected. The moving rod 38 is in the retracted position (corresponding to the hook body 2 retracting into the housing). The moving block 37 in the slot 36 is also in the starting position of its stroke (e.g., the leftmost or rightmost end, depending on the initial phase).

[0039] 5. Preparing to weave (dynamic start): Hold the yarn to be woven in your left hand, and prepare to operate the external switch on the hook housing 1 with your right hand (or use foot control according to preference). The device is still in a static state, waiting for the start signal.

[0040] 6. Start weaving (dynamic operation): Press (or step on) the external switch to start the drive motor 31. Drive motor 31: When powered on, its output shaft (hexagonal prism shape) begins to rotate.

[0041] 7. Insertion slot 33 and rotating column 35: The output shaft of the drive motor 31 is tightly inserted into the matching hexagonal prism insertion slot 33 at the end of the rotating column 35 to ensure torque transmission without slippage, and the rotating column 35 begins to rotate on the transmission frame 34.

[0042] 8. Slot 36 and Moving Block 37: The rotation of the rotating column 35 drives the horizontally circumferential slot 36 on its outer wall to rotate synchronously. One end of the moving block 37 is precisely locked in the slot 36 (the width of the slot is equal to the diameter of the moving block to ensure no shaking and smooth guidance). As the slot 36 rotates, its specific circumferential trajectory forces the moving block 37 to slide in the slot 36, while the whole moves in a reciprocating linear motion relative to the shell.

[0043] 9. Moving rod 38: The other end of the moving block 37 is connected to the moving rod 38. The left and right reciprocating motion of the moving block 37 is directly transmitted to the moving rod 38. The moving rod 38 itself is slidably connected to the bottom end of the transmission frame 34, so it can smoothly follow the moving block 37 to make strict left and right reciprocating linear motion.

[0044] 10. Hook body 2: The outer end of the moving rod 38 drives the hook body 2, which is rigidly connected to it, to perform high-speed reciprocating extension and retraction motion (extend -> retract -> extend...) along a straight track inside the hook outer shell 1.

[0045] 11. Overall operation: The drive motor 31 rotates continuously, driving the rotating column 35 to rotate efficiently and reliably through the hexagonal prism insertion. The rotational motion is converted into the linear reciprocating motion of the moving block 37 through the precise surrounding slot 36. The moving block 37 pushes the moving rod 38, ultimately driving the hook body 2 to perform high-frequency and precise extension and retraction movements. The entire transmission chain (motor shaft -> rotating column -> slot -> moving block -> moving rod -> hook) runs stably and with low vibration under the constraint and support of the support frame 32, transmission frame 34, slider 42 and slide 41, realizing the basic "fully automatic" hook operation. The user's left hand coordinates with the extension and retraction rhythm of the hook to perform operations such as threading and hanging.

[0046] 12. Continuous weaving (dynamic operation): Keep the external switch on (or operate intermittently as needed), and use your left hand to continuously and skillfully coordinate with the rhythm of the extension and retraction of the hook body 2 to perform weaving actions such as feeding the yarn, guiding the yarn, and pulling the loop. Your right hand (if not holding the switch) can assist in managing the yarn.

[0047] 13. Structural Movement and Coordination: Similar to step 4, the hook body 2 continuously and stably performs reciprocating extension and retraction movements. The frequency is determined by the motor speed. All moving parts (rotating column, sliding block in slot and overall linear motion, sliding rod, hook extension and retraction) continuously coordinate their operation. The slider 42 remains stationary in the slide groove 41 (because the transmission frame 34 is fixed by the threaded rod 44), serving only as the sliding constraint basis of the frame. The threaded rod 44 bears the reaction force when the transmission frame 34 is working, ensuring that the entire transmission mechanism will not shake or shift.

[0048] 14. Knitting complete (dynamic stop): When the knitting is finished, release the external switch, drive motor 31 stops rotating, rotating column 35 stops rotating, slotting 36 stops moving, moving block 37 stops at its current position, moving rod 38 and hook body 2 stop at their current extension / retraction position (which may be extended or retracted), and all moving parts stop instantly.
