Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to a hook. Background Technology

[0002] Hooks are a common tool in people's lives, mainly used to hang items. Traditional hooks have a relatively simple structure and function. As people's living standards gradually improve, their demand for personalized daily necessities is also increasing. Especially for the huge young consumer market, traditional hooks can no longer meet the personalized pursuits of young consumers because they can only realize the function of hanging items.

[0003] Chinese patent application No. 201721649793.5 discloses a face-changing toy, including a shell and a rotating component rotatably disposed within the shell; at least two masks and at least two magnets corresponding to the positions of each mask are arranged on the rotating component along the rotation circumference; the shell is provided with a window for the mask to be exposed when rotated to the window position.

[0004] In the above technical solution, the face mask located on the rotating part is manually flipped to change the face mask. However, the above technical solution cannot be combined with existing daily necessities, such as hooks. When users need to add fun to the use of hooks that only have a single function, the toy can only be fixed to the front of the hook rod or the hook can be fixed to the bottom of the toy so that it faces the user. This way, the user can use the toy to change the face mask before or after hanging an item. It is not possible for the toy to change the face mask and rotate while the user is hanging an item, so the use effect is not good. Summary of the Invention

[0005] To address the shortcomings of existing technologies, a hook is provided.

[0006] This utility model is achieved using the following technical solution:

[0007] A hook includes a housing and a hook body that can slide within the housing. The housing includes a head with a face window. A columnar rotating body is rotatably connected within the head, directly opposite the face window. The rotation axis of the rotating body coincides with its own axis. The hook body includes a straight rod and a hook at the bottom of the straight rod. A lifting groove along the length of the straight rod is provided on the side of the housing away from the face window. The straight rod is located within the lifting groove, and the hook is located outside the housing. At least one axial end of the rotating body has a connecting arm. The end of the connecting arm away from the rotation axis has a hinge rod parallel to the axis of rotation. The top of the straight rod has a meshing groove with an opening facing the hinge rod. The hinge rod is located within the meshing groove and can slide adaptively to achieve a hinge between the straight rod and the connecting arm. A stop assembly is provided within the rotation axis to stop the rotating body from rotating and to reset it.

[0008] When the user needs to use the hook, the item is hung on the hook section. The hook section pulls down the hinge rod located in the interlocking groove through the straight rod section, causing the connecting arm connected to the hinge rod to drive the rotating body to rotate, thereby changing the part of the rotating body that corresponds to and is exposed on the face window. At this time, the rotating body changes face once. Under the action of the rotation stop component, when the user removes the item hanging on the hook section, the rotating body can no longer rotate on its own. When the user hangs the item again, the hook section drives the rotating body to continue rotating, so that the face can be changed again.

[0009] This invention combines the function of a face-changing toy with the everyday item of a hook by having the hook rotate when the user hangs an item on it, thereby changing the part of the rotating body that corresponds to and is exposed on the face window. This breaks the limitation of the traditional hook's single function and adds fun to the process of hanging items, satisfying consumers, especially young consumers, for personalized and fun everyday items.

[0010] The rotating body can be a barrel-shaped structure or a prism-shaped structure with several arc-shaped surfaces arranged along the circumference. The surface used each time to correspond to the face window can be set according to actual needs, such as the shape of a person's head, or the shape of an animal's or other cartoon character's head.

[0011] Preferably, the hook body includes, from top to bottom, a biting part, a straight rod part, and a bent hook part. The biting part has a U-shaped biting groove, and the hinge rod is embedded in the biting groove. The straight rod part has a protrusion in the direction away from the rotating body. When the protrusion abuts against the bottom wall of the lifting groove, it is the lower limit position for the hook body to slide downward. When the hinge rod is pulled to the lower limit position by the biting part, the hinge rod abuts against the arc wall of the biting groove.

[0012] Compared to the method of opening a biting groove in the straight rod section, by setting a biting part, the hook section and the straight rod section pull down the hinge rod through the biting part, which can ensure the structural strength of the straight rod section of the hook body and prevent the hook body from breaking when the user hangs items.

[0013] Preferably, a tension spring is provided between the back side of the straight rod and the housing, and the direction of the tension spring coincides with the length direction of the straight rod.

[0014] By incorporating a tension spring, the hook body can automatically reset itself after the user removes the item from it, allowing the user to subsequently modify the parts of the rotating body that correspond to and are exposed on the face window.

[0015] Preferably, the rear end face of the biting part is in the same direction as the back side of the straight rod part, the rear end face of the biting part extends rearward until the tension spring is located at the lower end of the biting part, and the rear end of the biting part is provided with a clearance space for the tension spring to pass through.

[0016] By extending the engagement portion backward and positioning the tension spring at the lower end of the engagement portion, the tension spring is brought as close as possible to the straight rod portion in the axial direction, thereby making the axial forces of the tension spring and the straight rod portion as coaxial as possible, preventing the straight rod portion from bending or breaking under force.

[0017] Preferably, two limiting posts are symmetrically arranged inside the housing and located on the lower side of the rotating body. A limiting pressure plate located at the front end of the straight rod is fixed between the two limiting posts. The limiting pressure plate is provided with a limiting groove that matches the shape of the outer circular surface of the straight rod and allows the straight rod to pass through.

[0018] By setting a limiting pressure plate to limit the sliding trajectory of the straight rod, the straight rod can reciprocate in the vertical direction.

[0019] Preferably, the rotating stop assembly includes a support shaft fixedly supported in the rotating body and two sets of axial meshing parts sleeved on the outer circular surface of the support shaft. Each set of axial meshing parts includes a rotating shaft and a sliding shaft arranged facing each other and meshing with each other at their axial contact ends. The two sliding shafts are located in the rotating body. While driving the rotating body to rotate, the two sliding shafts can slide relative to the inner wall of the rotating body. A thrust spring is provided at one end of the two sliding shafts that are close to each other. The two rotating shafts extend outward from the rotating body. The rotating shaft located on the outer side of the rotating body is used for connection of the front end of the connecting arm.

[0020] When the rotating body rotates in the forward direction relative to the support shaft via the rotating shaft, the rotating shaft drives the sliding shaft to rotate synchronously. When the rotating body rotates in the reverse direction relative to the support shaft via the rotating shaft, the rotating shaft pushes the sliding shaft through the meshing teeth and compresses the spring, thereby making the rotating body correspond to the face window and be exposed.

[0021] Preferably, the meshing teeth between the rotating shaft and the sliding shaft are provided with a plurality of teeth along the circumferential direction, and each meshing tooth includes a first tooth surface and a second tooth surface along the circumferential direction, wherein the inclination angle between the first tooth surface and the axis is greater than the inclination angle between the second tooth surface and the axis.

[0022] When the rotating body rotates forward relative to the support shaft via the rotating shaft, the second tooth surface between the rotating shaft and the sliding shaft abuts against each other, allowing the rotating shaft to drive the sliding shaft to rotate synchronously. When the rotating body rotates in the opposite direction relative to the support shaft via the rotating shaft, the first tooth surface between the rotating shaft and the sliding shaft abuts against each other, generating an axial thrust that causes the sliding shaft to separate from the rotating shaft and compress the thrust spring inward. The rotating shaft can no longer drive the sliding shaft to rotate synchronously, thus achieving unidirectional intermittent rotation of the sliding shaft, thereby keeping the rotating body in the part corresponding to and exposed to the face window.

[0023] Preferably, the outer surfaces of the two sliding shafts are fixedly provided with support members for supporting the rotating body, and the support members can slide relative to the rotating body.

[0024] Among them, the support component can be any existing component that can drive the rotating body to rotate synchronously and slide relative to it, such as a flat key and keyway, a spline and keyway, a slider and a slider groove opened inside the rotating body, etc.

[0025] Preferably, there are two connecting arms symmetrically arranged on both sides of the axial direction of the rotating body. The connecting arms are symmetrically provided with curved sections for bringing the ends of the two connecting arms closer to each other. The connecting rod is connected between the ends of the two connecting arms, thereby shortening the length of the connecting rod, ensuring the structural strength of the connecting rod, preventing the connecting rod from bending and deforming after long-term use, and saving space inside the housing.

[0026] Preferably, the back of the housing is provided with a mounting groove for engaging with the adhesive protrusion, thereby facilitating the assembly of the housing to the wall by adhesive.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] By combining the function of a face-changing toy with a household item like a hook, users can hang items on the hook and cause the rotating part to rotate, thus changing the part of the rotating part that corresponds to the face window and is exposed. After the hook rebounds, the rotating part remains relatively stationary, visually achieving the face-changing effect in conjunction with the shell. This breaks the limitation of the traditional hook's single function and adds fun to the process of hanging items, satisfying consumers, especially young consumers,'s pursuit of personalized and fun everyday items.

[0038] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0039] like Figure 1 As shown, this embodiment discloses a hook, including a housing 11 and a hook body 13 that can slide within the housing 11. The back of the housing 11 is provided with a mounting groove 112 for use with an adhesive patch in the prior art, such as... Figure 2 As shown, the housing 11 includes a head 12, on which a face window 121 is provided. A support rod 15 is fixedly installed inside the head 12, spanning the left and right sides of the head 12. Figure 4As shown, a columnar rotating body 16 is rotatably connected inside the head 12, directly opposite the face window 121. The rotating body 16 is sleeved on the support rod 15 and its own rotation axis coincides with the axis of the support rod 15. The rotating body 16 includes two interlocking covers. One cover is provided with a pin, and the other cover is provided with a hole corresponding to the position of the pin. Two sets of axial meshing parts are sleeved on the outer circular surface of the support rod 15.

[0040] like Figure 5 As shown, both sets of axial meshing components include a rotating shaft 17 and a sliding shaft 18 that are arranged facing each other and mesh with each other at their axial contact ends. There are several meshing teeth 19 between the rotating shaft 17 and the sliding shaft 18 along the circumferential direction. Each meshing tooth 19 includes a first tooth surface 191 and a second tooth surface 192 along the circumferential direction. The inclination angle between the first tooth surface 191 and the axis is greater than the inclination angle between the second tooth surface 192 and the axis. The two sliding shafts 18 are located inside the rotating body 16. While driving the rotating body 16 to rotate, the two sliding shafts 18 can slide relative to the inner wall of the rotating body 16. A thrust spring 21 is provided at one end of the two sliding shafts 18 that is close to each other. The two rotating shafts 17 extend outward from inside the rotating body 16. The rotating shaft 17 located outside the rotating body 16 is used to connect the front end of the connecting arm 20.

[0041] like Figure 6 As shown, the outer circular surfaces of the two sliding shafts 18 are fixed with outwardly extending buckles 181, and the inside of the cover is provided with a slot 161 for engaging with the buckles 181. When the sliding shafts 18 rotate, the sliding shafts 18 abut against the inner wall of the slot 161 through the buckles 181, thereby driving the cover to rotate, which in turn drives the rotating body 16 to rotate.

[0042] The hook body 13 includes, from top to bottom, a biting part 131, a straight rod part 132, and a curved hook part 133, as follows: Figure 3 As shown, a U-shaped engagement groove 1311 is provided in the engagement part 131. The rear end face of the engagement part 131 and the back side of the straight rod part 132 are in the same direction. The rear end face of the engagement part 131 extends rearward until the tension spring 14 is located at the lower end of the engagement part 131. The rear end of the engagement part 131 is provided with a clearance space 1312 for the tension spring 14 to pass through. A lifting groove 111 along the length of the straight rod part 132 is provided on the side of the housing 11 away from the face window 121. The straight rod part 132 is located in the lifting groove 111 and the hook part 133 is located on the outside of the housing 11. Figure 8 As shown, the straight rod 132 has a protrusion 134 in the direction away from the rotating body 16. When the protrusion 134 abuts against the top wall or bottom wall in the lifting slide 111, it is recorded as the upper and lower limit positions of the hook body 13 sliding.

[0043] like Figure 7As shown, two limiting posts 23 are symmetrically arranged inside the housing and located on the lower side of the rotating body 16. A limiting pressure plate 24 located at the front end of the straight rod is fixed between the two limiting posts 23. The limiting pressure plate 24 is provided with a limiting groove 241 that matches the shape of the outer circular surface of the straight rod 132 and allows the straight rod to pass through.

[0044] A connecting arm 20 is provided on the outer circular surface of the rotating shaft 17. There are two connecting arms 20, which are symmetrically arranged on both sides of the axial direction of the rotating body 16. The connecting arms 20 are symmetrically provided with curved sections 201 for bringing the ends of the two connecting arms 20 closer to each other. A hinge rod 22 is connected between the ends of the two connecting arms 20. The end of the connecting arm 20 away from the rotating shaft is provided with a hinge rod 22 parallel to the axis of the rotating shaft 17. The hinge rod 22 is embedded in the engagement groove 1311. The hinge rod 22 is located in the engagement groove 1311 and can slide relatively adaptively to realize the hinge between the straight rod part 132 and the connecting arm 20.

[0045] The rotating shaft 17 has an expanded diameter section 171 at one end located outside the rotating body 16. The expanded diameter section 171 has a square cross-section. The front end of the connecting arm 20 has a wrapping section 202 that can wrap around the outside of the expanded diameter section 171. The expanded diameter section 171 and the wrapping section 202 slide together to achieve a detachable connection.

[0046] When the user needs to use the hook, the item is suspended on the hook portion 133. The weight of the item causes the hook portion 133 to move downwards. The hook portion 133 pulls down the hinge rod 22 located in the engagement groove 1311 via the straight rod portion 132, and stretches the tension spring 14. The hinge rod 22 slides adaptively within the engagement groove 1311 and drives the connected connecting arm 20 to rotate. The connecting arm 20 rotates the expanding section 171 through the wrapping section 202, thereby driving the rotating shaft 17 to rotate forward. At this time, the second tooth surface 192 between the rotating shaft 17 and the sliding shaft 18 abuts against each other. The rotating shaft 17 drives the sliding shaft 18 to rotate synchronously in the forward direction, thereby changing the part of the rotating body 16 that corresponds to and is exposed by the face window 121. When the object moves the hook part 133 due to inertia, the tension spring 14 retracts. At this time, the tension spring 14 drives the straight rod part 132 to slide upward. The straight rod part 132 pushes the hinge rod 22 upward through the engagement groove 1311, thereby driving the rotating shaft 17 to rotate in the opposite direction. The first tooth surface 191 between the rotating shaft 17 and the sliding shaft 18 abuts against each other. At this time, an axial thrust is generated between the two, causing the sliding shaft 18 to separate from the rotating shaft 17 and compress the thrust spring 21 inward. The rotating shaft 17 cannot drive the sliding shaft 18 to rotate synchronously, thereby realizing the unidirectional intermittent rotation of the sliding shaft 18, so that the rotating body 16 is kept in the part corresponding to and exposed to the face window 121, that is, the face change is completed.

[0047] When the user removes the item from the hook 133, the tension spring 14 returns to its initial state and drives the straight rod 132 to continue moving upward. At this time, the rotating shaft 17 continues to reverse, and the rotating body 16 cannot rotate on its own, thus maintaining the angle of the rotating body 16 within the face window 121. When the user hangs the item again, the hook 133 drives the rotating body 16 to continue rotating, and the face can be changed again.
