[0001] The utility model relates to a hidden hook steering device and a suction cup hook applying the same. Background Art
[0002] At present, in order to better adapt to fixing surfaces at different angles, the commonly used hook products in people's lives often divide the connecting rod between the hook and the fixing surface into two sections, and a hinge device is arranged at the connection of the two connecting rods, so that the hook can rotate relative to the connecting rod fixed on the fixing surface, thereby changing the orientation of the hook. In this way, the hook can change its orientation by rotation to adapt to fixing surfaces at different angles.
[0003] However, such hinge devices for realizing hook steering are often exposed, which may cause the hinge device to be easily affected by the outside and fail. In addition, in addition to the exposed hinge device, corresponding connection structures generally need to be arranged on the connecting rod of the hook to adapt to the structure of the hinge device. These exposed connection structures and hinge devices will make the hook products with steering functions have worse integrity and aesthetics in appearance compared with the hook products without steering functions, thereby reducing consumers' purchase desire and affecting the product competitiveness.
[0004] Therefore, how to overcome the above-mentioned existing defects has become an important issue that needs to be solved urgently by those skilled in the art. Content of the Utility Model

The grooves 52 are circumferentially distributed around the rotation axis of the hidden plug-in rotation structure 4. The convex block 51 can rotate with the corner portion and fall into any one of the grooves 52 to form a concave-convex fit to relatively fix the first connecting rod 1 and the second connecting rod 2. The contour edges of the convex block 51 are all smooth arc surfaces.
[0011] Preferably, the cross-sectional contours of the first connecting rod 1, the second connecting rod 2, the first corner portion 11, and the second corner portion 21 are all the same.

[0025] The features of the present utility model and other related features are further described in detail through the following embodiments for the understanding of those skilled in the same industry:
[0026] Such as Figures 1 to 5As shown in the figure, a concealed hook steering device includes a first connecting rod 1. One end of the first connecting rod 1 is used to connect with a hook fixing structure, and the other end is connected with a second connecting rod 2. The end of the second connecting rod 2 is connected with a hook 3. One end of the first connecting rod 1 close to the second connecting rod 2 is provided with a first corner portion 11 extending towards the second connecting rod 2. One end of the second connecting rod 2 close to the first connecting rod 1 is provided with a second corner portion 21 extending towards the first connecting rod 1. The end faces of the first corner portion 11 and the second corner portion 21 are attached and connected by a concealed plug-in rotating structure 4 to facilitate relative rotation of the two corner portions. The end face contour of the first corner portion 11 and the end face contour of the second corner portion 21 are the same and the contour is rotationally symmetric about the rotation axis of the concealed plug-in rotating structure 4.
[0027] In the concealed hook steering device of this case, corner portions are respectively provided at the first connecting rod 1 and the second connecting rod 2, and the first corner portion 11 and the second corner portion 21 are connected by a concealed plug-in rotating structure 4. With the help of the concealed plug-in rotating structure 4, the end faces of the first corner portion 11 and the second corner portion 21 can be kept in contact, and the two can rotate relative to each other with the rotation axis of the concealed plug-in rotating structure 4 as the rotation axis. In this way, the orientation of the hook 3 can be changed by the relative rotation of the first corner portion 11 and the second corner portion 21, so that the hook 3 can adapt to fixing surfaces at different angles. At the same time, since the first corner portion 11 and the second corner portion 21 are connected by plugging and docking through the concealed plug-in rotating structure 4, the connection structure will not be exposed outside. In addition, the end face contours of the first corner portion 11 and the second corner portion 21 are the same and rotationally symmetric about the rotation axis of the concealed plug-in rotating structure 4. In this way, after the first corner portion 11 and the second corner portion 21 rotate relative to each other by a specified angle, the contours of the first corner portion 11 and the second corner portion 21 are still coincident, which can maintain the consistency of the appearance of the steering device.
[0028] As described above, the concealed hook steering device of this case connects the first corner portion 11 and the second corner portion 21 through the concealed plug-in rotating structure 4, thereby realizing the relative rotation of the first connecting rod 1 and the second connecting rod 2, so that the orientation of the hook 3 can be changed to adapt to fixing surfaces at different angles. At the same time, since the first corner portion 11 and the second corner portion 21 are connected by plugging and docking through the concealed plug-in rotating structure 4, the concealed hook steering device of this case has no exposed hinge device, and the end face contours of the first corner portion 11 and the second corner portion 21 are also the same and rotationally symmetric. There is a smooth transition connection between the first connecting rod 1 and the second connecting rod 2 in appearance. In this way, not only can the structure of the steering device be prevented from being exposed outside, thereby reducing the probability of failure due to external influence, but also the aesthetic degree of the concealed hook steering device of this case can be greatly improved, thereby increasing the purchase desire of consumers and enhancing the competitiveness of the product in the market.
[0029] As shown in Figures 1 to 5 the figure, preferably, the end faces of both corner portions are perpendicular to the rotation axis of the hidden plug-in rotating structure 4. The hidden plug-in rotating structure 4 includes a plurality of convex buttons 41 provided on one of the corner portions and a card hole 42 provided on the other corner portion for all the convex buttons to be inserted therein. The convex buttons 41 are arranged on the end face of the corner portion and extend along the rotation axis of the hidden plug-in rotating structure 4 towards the other corner portion. All the convex buttons 41 are circumferentially distributed around the rotation axis of the hidden plug-in rotating structure 4. An outwardly protruding buckle portion 411 is provided at the extending end of the convex button 41. The axis of the card hole 42 coincides with the rotation axis of the hidden plug-in rotating structure 4. A lapping limit surface 421 for the buckle portion 411 to rest on and prevent the buckle portion 411 from disengaging from the card hole 42 is provided at the inner end of the card hole 42.
[0030] As described above, when the two corner portions are butt-joint connected, the end faces of the two corner portions approach each other, so that the convex buttons 41 will be inserted into the card holes 42. During the insertion process, the buckle portion 411 will be deformed inwardly under the extrusion of the wall surface of the card hole 42. When the two corner portions are butted in place, the buckle portion 411 will extend out of the card hole 42 and lap on the lapping limit surface 421. In this way, the convex button 41 cannot withdraw from the card hole 42 under the cooperation and limitation of the buckle portion 411 and the lapping limit surface 421, and thus the two corner portions are completed with butt-joint fixation. In addition, the convex buttons 41 extend along the rotation axis of the hidden plug-in rotating structure 4 and are circumferentially distributed around the rotation axis. The axis of the card hole 42 also coincides with the rotation axis of the hidden plug-in rotating structure 4. In this way, the convex buttons 41 limited on the card hole 42 can serve as the rotating shaft for the relative rotation of the two corner portions, and the card hole 42 can serve as the shaft hole of the rotating shaft. In this way, by connecting the two corner portions through the hidden plug-in rotating structure 4, the two corner portions can be fixed while allowing the two corner portions to achieve relative rotation. Moreover, since the convex buttons 41 and the card holes 42 are both arranged on the end faces of the corner portions, when the two corner portions are butted and completed, the end faces are in contact, and the convex buttons 41 and the card holes 42 will both be hidden and not exposed.
[0031] As shown in Figures 1 to 5 the figure, preferably, a rotation positioning structure 5 is further provided at the joint of the first corner portion 11 and the second corner portion 21 to facilitate the relative fixation of the first corner portion 11 and the second corner portion 21. In this way, when the first corner portion 11 and the second corner portion 21 rotate relatively, the first corner portion 11 and the second corner portion 21 can be relatively fixed through the rotation positioning structure 5, so that the orientation of the hook 3 is relatively fixed without external force intervention.
[0032] As shown in Figures 1 to 5As shown, preferably, the rotation positioning structure 5 includes a convex block 51 provided on the end face of one corner portion and a plurality of grooves 52 provided on the end face of the other corner portion. The grooves 52 are circumferentially distributed around the rotation axis of the hidden plug-in rotation structure 4. The convex block 51 can rotate with the corner portion and fall into any one of the grooves 52 to form a concave-convex fit, so as to relatively fix the first connecting rod 1 and the second connecting rod 2. The contour edges of the convex block 51 are all smooth arc surfaces.
[0033] As described above, when the user rotates one of the corner portions, the convex block 51 and the grooves 52 will also rotate relative to each other with the rotation axis of the hidden plug-in rotation structure 4 as the rotation axis. When the corner portion rotates a certain angle, the convex block 51 will fall into one of the grooves 52. In this way, the convex block 51 and the groove 52 will form a concave-convex fit, generating resistance to the rotation of the corner portion so that the corner portion cannot rotate freely without external intervention, thereby realizing the relative fixation of the two corner portions and then fixing the orientation of the hook 3. When the user wants to adjust the orientation of the hook 3, just rotate one of the corner portions forcefully. Since the contour edges of the convex block 51 are smooth arc surfaces, it can be disengaged from the groove 52 under force, so that the orientation of the hook 3 can be adjusted.
[0034] As Figures 1 to 5 As shown, preferably, the cross-sectional contours of the first connecting rod 1, the second connecting rod 2, the first corner portion 11, and the second corner portion 21 are all the same. In this way, the first connecting rod 1, the second connecting rod 2, the first corner portion 11, and the second corner portion 21 can all maintain the consistency of the appearance, further improving the simplicity of the product and increasing the purchasing desire of consumers.
[0035] As Figures 1 to 5 As shown, preferably, the cross-sectional contours of the first corner portion 11 and the second corner portion 21 are both circular. In this way, no matter how many angles the first corner portion 11 and the second corner portion 21 rotate relative to each other, the contours of the two corner portions can always be aligned, further improving the appearance simplicity of the product.
[0036] As Figures 1 to 5 As shown, preferably, the first connecting rod 1 and the second connecting rod 2 are perpendicular to each other, and the included angles formed by the rotation axis of the hidden plug-in rotation structure 4 and the first connecting rod 1 and the second connecting rod 2 are both 45°. In this way, when the two corner portions rotate 180° relative to each other, the first connecting rod 1 and the second connecting rod 2 can be switched from a perpendicular state to a parallel state, which can just correspond to the two common states of the hook fixing structure being side-mounted and top-mounted.
[0037] As Figures 1 to 5As shown, preferably, there are two grooves 52. The two grooves 52 are centrosymmetric about the rotation axis center of the hidden plug-in rotation structure 4. When the first connecting rod 1 and the second connecting rod 2 are perpendicular to each other, the convex block 51 falls into one of the grooves 52. When the first connecting rod 1 and the second connecting rod 2 are parallel to each other, the convex block 51 falls into the other groove 52. In this way, the positioning positions of the groove 52 and the convex block 51 exactly correspond to the states where the first connecting rod 1 and the second connecting rod 2 are perpendicular and parallel to each other.
[0038] As Figures 1 to 5 shown, preferably, the hook 3 includes a plurality of hook bodies 31 extending outward circumferentially around the side surface of the second connecting rod 2. In this way, no matter what angle the first corner portion 11 and the second corner portion 21 rotate relative to each other, it can be ensured that there are hook bodies 31 in different directions for the user to hang objects.
[0039] As Figures 1 to 6 shown, a suction cup hook includes the above-mentioned hidden hook steering device. One end of the first connecting rod 1 away from the second connecting rod 2 is connected with a suction cup 6.
[0040] As described above, the suction cup hook in this case can fix the whole suction cup hook to the fixing surface by the adsorption of the suction cup 6, and then can conveniently adjust the orientation of the hook 3 through the adjustment of the hidden hook steering device. The hidden hook steering device can hide the rotation structure in the first corner portion 11 and the second corner portion 21, making the appearance of the suction cup hook in this case more concise and beautiful. At the same time, it can also avoid the failure of the steering device due to external influences, thereby improving the competitiveness of the product.
[0041] As Figures 1 to 6 shown, preferably, a connecting seat 12 is further provided at one end of the first connecting rod 1 away from the second connecting rod 2. A buckle 13 for fixedly connecting with the suction cup 6 is provided on the back surface of the connecting seat 12. In this way, the suction cup 6 can be conveniently fixed to the first connecting rod 1.
[0042] As described above, what is protected in this case is a hidden hook steering device and a suction cup hook applying the same. All technical solutions identical or similar to this case should be regarded as falling within the protection scope of this case.
