Description

Technical Field

[0001] This utility model relates to the field of knitting tool technology, and in particular to a crochet hook with a detachable hook head. Background Technology

[0002] A crochet hook is a tool used for knitting, primarily for crocheting various fabrics and handicrafts, such as clothing, scarves, hats, gloves, bags, flowers, and dolls. With a crochet hook, a single thread can be woven into a piece of fabric, which can then be combined to create various items. Considering different thread thicknesses, different crocheting effects, and individual crocheting habits, crochet hooks typically require various sizes to meet different needs, such as small hooks with a body diameter of 4.0mm and large hooks with a body diameter of 10.0mm.

[0003] A common crochet hook structure can be found in patent 201410820528.3, which discloses a crochet hook and a handle for the hook. The handle comprises a rod-shaped needle body with a hook at its tip, and the tip of the needle body protrudes to cover the base side. The needle body and the handle are fixedly connected and not easily disassembled. For crochet enthusiasts, if multiple hook sizes are needed, multiple crochet hooks must be purchased, which not only increases expenses and wastes resources, but also takes up more space when stored and is inconvenient to carry when traveling. Utility Model Content

[0004] The technical problem to be solved by this utility model is to propose a hook needle with a detachable hook head that is easy to replace with hook heads of different specifications, in view of the above-mentioned technical status.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a hook with a detachable hook head, comprising...

[0006] Handle;

[0007] The hook head is rod-shaped, with a hook at the top and a handle at the bottom, the handle being inserted into the top of the handle;

[0008] Its features are,

[0009] The handle includes a handle housing and a connector disposed within the top of the handle housing. The connector has an axial channel into which a shank portion is inserted. The bottom end of the connector is elastic and tends to lock the shank portion inserted into the axial channel, thereby allowing the hook head to be detachably connected to the connector.

[0010] To facilitate the detachable connection between the insert and the connector, preferably, the peripheral wall of the insert is provided with a groove, and the inner wall of the connector is provided with a locking point, which is engaged into the groove.

[0011] The connector is made of plastic. In order to have sufficient elasticity to clamp the insert portion into the connector, preferably, the bottom end of the connector is cut into at least two halves along the axial direction, so that the bottom end of the connector has elasticity.

[0012] In order to allow the insert to be more fully embedded in the connector, preferably, the inner diameter of the connector gradually increases from the bottom to the top, so that the insert and the connector fit tightly together.

[0013] To prevent the hook from rotating relative to the connector, preferably, the opening of the axial channel is an irregular circle with a constricted edge.

[0014] The connector is disposed inside the grip housing. Specifically, the grip housing includes a grip outer shell and a grip inner shell. The grip inner shell has a top section and a bottom section. The inner diameter of the top section is larger than the inner diameter of the bottom section. A stepped surface is formed at the junction of the top and bottom sections of the grip inner shell due to the change in inner diameter. The connector is disposed in the top section of the grip inner shell, and the bottom end of the connector abuts against the stepped surface.

[0015] Furthermore, the top of the grip shell has a constricted portion that restricts the grip inner shell inside the grip shell. The inner wall of the constricted portion has a circumferentially surrounding protrusion located on the top outer side of the grip inner shell. There is a gap between the protrusion and the top side of the grip inner shell. The connector has an annular retaining strip that engages with the gap.

[0016] Furthermore, the connector has a groove, and the protrusion of the handle shell is correspondingly engaged in the groove.

[0017] To ensure a more secure assembly of the handle outer shell, handle inner shell, and connector, the hook preferably includes a fixing sleeve. The top of the connector extends beyond the handle outer shell, and the outer side of the top of the connector is provided with an annular rib. The fixing sleeve is provided with a corresponding annular recess. The fixing sleeve is fitted onto the closed portion of the handle outer shell and the outer side of the top of the connector. The annular rib is correspondingly inserted into the annular recess. The fixing sleeve and the connector cooperate to fix the handle outer shell.

[0018] To enhance user comfort, both the outer and inner shell of the grip are preferably made of a soft, elastic material. This soft, elastic material can be a gel, which deforms according to the user's point of force application to achieve the most comfortable grip during use.

[0019] Compared with the prior art, this utility model adds a connector inside the handle, and the hook head and the connector can be inserted into each other. The bottom end of the connector has a certain degree of elasticity, which can lock the inserted hook head shank, and the shank will not detach from the connector due to disturbance; however, when the user applies enough force, the hook head can be removed and replaced with other specifications of hook heads to meet the user's needs for various sizes of crochet hooks, so that the user does not need to buy multiple crochet hooks.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] like Figures 1-7 The image shows a preferred embodiment of a hook with a detachable hook head according to this utility model.

[0029] The crochet hook of this embodiment includes a handle 1 and a hook head 2. The main body of the hook head 2 is rod-shaped, such as... Figure 1 As shown, the top end has a hook portion 21, and the bottom end has a handle portion 22, which is inserted into the top of the grip 1. The grip 1 includes a grip housing and a connector 13 disposed within the top of the grip housing. (Refer to...) Figures 2-4The connector 13 has an axial channel 134 into which the insert shank 22 is inserted. The bottom end of the connector 13 is elastic and always tends to lock the insert shank 22 inward, thereby making the hook head 2 detachable. To accommodate different yarns and projects, this embodiment includes multiple replaceable hook heads 2 of different specifications. The diameter of the insert shank 22 of each hook head 2 is the same, but the size of the hook portion 21 of each hook head 2 is different, ranging from 4.0mm to 10.0mm from small to large. Figure 7 As shown. Based on the aforementioned detachable feature of the hook head 2, the user can simply insert the desired hook head 2 into the handle 1 for use. If the user finishes using it or wants to replace the hook head 2, they can simply pull the insertion part 22 of the hook head 2 out of the handle 1. The operation is simple.

[0030] In this embodiment, the peripheral wall of the insertion handle 22 is provided with a groove 221, and the inner wall of the connector 13 is provided with a locking point 135. The locking point 135 is engaged with the groove 221, thereby realizing a detachable connection between the insertion handle 22 and the connector 13. The connector 13 is made of plastic, and its bottom end is cut along the axial direction into... Figure 6 (a) and Figure 6 (b) shows the four-lobed wrapping portion 136, which provides sufficient elasticity at the bottom end of the connector 13 to clamp the inserted handle portion 22. In this embodiment, to allow the handle portion 22 to be more fully embedded in the connector 13, the inner diameter of the connector 13 gradually increases from the bottom to the top, thereby ensuring a tight fit between the handle portion 22 and the connector 13. The opening of the axial channel 134 is an irregular circle with a constricted edge 137, preventing the hook 2 from rotating relative to the connector 13 after insertion.

[0031] In its natural state, the inner diameter of the bottom end of the connector 13 is slightly smaller than that of the bottom end of the insert 22; when the insert 22 is inserted, it will push the four-lobed wrapping portion 136 at the bottom end of the connector 13 outward, that is, the four-lobed wrapping portion 136 of the connector 13 can wrap around the bottom end of the insert 22 inward, such as Figure 3 As shown, at this time, the locking point 135 is tightly engaged in the slot 221, and the insert shank 22 will not detach from the connector 13 due to disturbance. However, when the user applies sufficient force, the hook head 2 can be disassembled and replaced with hook heads of other specifications to meet the needs of various crochet hook sizes.

[0032] The grip housing includes Figure 5 The outer grip shell 11 and inner grip shell 12 shown are both made of a soft, elastic material. The soft, elastic material can be a gel, which can deform according to the user's point of force to achieve the most comfortable grip during use.

[0033] The connector 13 is disposed inside the handle housing. Specifically, the inner handle housing 12 has a top section and a bottom section, the inner diameter of the top section being larger than the inner diameter of the bottom section. A stepped surface 121 is formed at the junction of the top and bottom sections of the inner handle housing 12 due to the change in inner diameter. Figure 3 As shown, the connector 13 is disposed at the front of the inner shell 12 of the handle, and the bottom end of the connector 13 abuts against the stepped surface 121. The top end of the outer shell 11 of the handle has a constricted portion 112, which restricts the inner shell 12 of the handle to the inside of the outer shell 11 of the handle. The inner wall of the constricted portion 112 is provided with a circumferentially surrounding protrusion 111, which is located on the top side of the inner shell 12 of the handle. There is a gap between the protrusion 111 and the top end of the inner shell 12 of the handle. The connector 13 is provided with an annular retaining strip 133, which is inserted into the gap. At the same time, the connector 13 is provided with a groove 132, and the protrusion 111 of the outer shell 11 of the handle is inserted into the groove 132.

[0034] To ensure a more secure assembly of the outer handle shell 11, the inner handle shell 12, and the connector 13, the hook in this embodiment also includes a fixing sleeve 4, as shown in the reference. Figure 3 and Figure 4 The top of the connector 13 extends beyond the handle housing 11. An annular rib 131 is provided on the outer side of the top of the connector 13. The fixing sleeve 4 is provided with a corresponding annular recess 401. The fixing sleeve 4 is fitted onto the closed part 112 of the handle housing 11 and the outer side of the top of the connector 13. The annular rib 131 is correspondingly inserted into the annular recess 401. The fixing sleeve 4 and the connector 13 cooperate to fix the handle housing 11.
