Description

Technical Field

[0001] The present application relates to the field of hanger racks, and in particular to an adjustable hanger rack. Background Art

[0002] Hanger racks are a kind of hanging or supporting tools widely used in industrial production and daily life, mainly used to fix, hang or transport workpieces and objects. Among them, household hangers are very practical storage tools in daily life, which can effectively utilize walls or three-dimensional spaces, help organize sundries, save space, and also play a decorative role.

[0003] In the related art, household hangers are usually divided into wall hooks, racks, hangers, and hanger rods, which are mainly used in kitchens, bathrooms, entrances, balconies, and other places. Most of the hangers on the market are fixed designs, which cannot meet the diverse hanging needs of items of different sizes and weights. With the improvement of people's living standards, higher requirements are put forward for the functionality and aesthetics of household items. Traditional fixed hangers have gradually failed to meet the needs of modern life.

[0004] Specifically, the hangers in the related art have the following defects. First, the traditional hooks are fixed in position, and the spacing cannot be flexibly adjusted according to the size of the items, resulting in low space utilization. For example, when large tools and small items are hung together, it is easy to crowd or waste wall space. Secondly, the load-bearing adaptability is poor. Most products are only designed for a single weight. Lightweight hooks are prone to deformation and falling off when hanging heavy objects, while heavy structures are bulky when hanging small objects. Third, there is a lack of angle adjustment, and the hook direction is single. Inclined objects (such as umbrellas and long-handled pots) are hung unstably, and accumulated water is difficult to drain.

[0038] The following is combined with Figure 1-10 This application is described in further detail.

[0039] The embodiment of the present application discloses an adjustable hanger rack.

[0040] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0041] Reference Figure 1 , Figure 2 and Figure 3An adjustable hanger rack includes a base plate 1, a first connecting module 2, and a second connecting module 4, wherein the base plate 1 is connected to the wall according to the installation position. After the base plate 1 is installed, the position of the hook 22 on the first connecting module 2 is adjusted to achieve fine adjustment of the hook 22. When the first connecting module 2 cannot meet the user's requirements, the second connecting module 4 is installed on the first connecting module 2. The second connecting module 4 has the function of a hanging rod, thereby effectively realizing the switching of the hanger rack function. The present application solves the problem of poor applicability and flexibility of the hanger rack in the related art to a certain extent.

[0042] Specifically, in the embodiment of the present application, the base plate 1 is detachably connected to the wall and can be pre-set at the position to be installed according to the position to be installed. As for the specific installation method, it can be to reserve threaded holes on the wall, or to directly use self-tapping screws to nail the base plate 1 to the wall, which are both preferred embodiments of the present application.

[0043] Specifically, the first connecting module 2 is movably connected to the substrate 1, and the first connecting module 2 includes a sliding block 21 and a hook 22. A groove 3 is opened on the substrate 1, and the sliding block 21 is slidably connected to the side wall of the groove 3. The hook 22 is fixedly connected to the end of the sliding block 21 away from the substrate 1. The hook 22 is rotatably connected to the sliding block 21. A plurality of first connecting modules 2 are provided, and the spacing between adjacent first connecting modules 2 is equal.

[0044] The setting of the groove 3 enables the sliding block 21 to slide within the range of the groove 3. In addition to enabling the sliding block 21 to slide accurately in the groove 3, the groove 3 can also form an abutment between the side wall of the groove 3 and the side wall of the sliding block 21 to prevent the sliding block 21 from twisting. Specifically, the groove 3 of the present application is arranged in a rectangular strip shape, and the sliding block 21 is arranged in a rectangular block, which effectively limits the possibility of the sliding block 21 rotating. At the same time, the first connecting module 2 is provided with multiple, that is, the sliding block 21 and the hook 22 are both provided with multiple, such a setting enables the hanger frame of the present application to hang multiple objects to be hung at one time.

[0045] Specifically, refer to Figure 4 The second connecting module 4 is detachably connected to the sliding block 21. The second connecting module 4 includes a connecting block 41 and a hanging rod group 42. The connecting block 41 can be sleeved on the sliding block 21. The hanging rod group 42 and the sliding block 21 are detachably connected. There are multiple connecting blocks 41, and the multiple connecting blocks 41 correspond one to one to the multiple sliding blocks 21.

[0046] In the embodiment of the present application, when the object to be hung is relatively light, the connection block 41 and the sliding block 21 can be made by interference fit. When the object to be hung is relatively heavy, a through hole can be provided on the connection block 41, and a plug hole can be provided on the sliding block 21, and then an additional plug pin is provided. After the connection block 41 and the sliding block 21 are interference fit, the plug pin is inserted into the through hole and the plug hole at the same time, so that the connection between the connection block 41 and the sliding block 21 is more stable. It should be noted that the present application only shows the interference fit between the connection block 41 and the sliding block 21. For the form of using a plug pin, when the plug pin is inserted into the through hole and the plug hole, it is parallel to the plane of the substrate 1, which is relatively easy to understand for those skilled in the art.

[0047] Specifically, in the embodiment of the present application, the adjustable hanger rack also includes an adjustment mechanism, which includes a first adjustment component 5 and a second adjustment component 8. The first adjustment component 5 is used to adjust the lateral position of the first connecting module 2, and the second adjustment component 8 is used to adjust the state of the hanging rod group 42.

[0048] The first adjusting component 5 can effectively adjust the lateral position, and the second adjusting component 8 can effectively change the state of the hanging rod group 42, thereby effectively achieving precise control of the hanger frame.

[0049] Specifically, the function of the first adjustment component 5 is to adjust the lateral position of the first connecting module 2, or it can be said to be fine-tuning, because the specific large range is placed according to the user's personalization, and the state of the hanging rod group 42 includes a storage table state and a hanging rod state. When in the storage table state, objects can be directly placed above the hanging rod group 42, and when in the hanging rod state, objects can be hung.

[0050] Further, see Figure 2 In the embodiment of the present application, the first adjustment component 5 includes a worm 51, a worm wheel 52, a connecting gear 53, and a connecting rack 54. The worm 51 is vertical and penetrates the plane of the base plate 1. The worm wheel 52, the connecting gear 53, and the connecting rack 54 are all located in the base plate 1. The worm wheel 52 is meshed with the worm 51. The connecting gear 53 is coaxially arranged with the worm wheel 52. A sliding groove is arranged in the base plate 1. The connecting rack 54 is slidably connected to the bottom wall of the sliding groove. The connecting rack 54 is meshed with the connecting gear 53. A connecting rod 6 is arranged on the side edge of the connecting rack 54. One end of the connecting rod 6 is fixedly connected to the side edge of the connecting rack 54, and the other end is fixedly connected to the sliding block 21. It should be noted that the sliding groove is not specifically shown in the drawings of the present application specification, which is relatively easy to understand for those skilled in the art, so it is not described in detail in the embodiment of the present application.

[0051] The arrangement of the worm wheel 52 , the worm 51 , the connecting gear 53 , and the connecting rack 54 effectively converts the rotational motion of the worm 51 into the linear motion of the connecting rack 54 , thereby driving the sliding block 21 to achieve lateral movement.

[0052] At the same time, an adjusting knob 7 is provided at one end of the worm 51 outside the base plate 1 .

[0053] The adjusting knob 7 makes it easier for the user to adjust the worm 51 .

[0054] In combination with the above content, the working principle of the first adjustment component 5 is explained. The specific working principle is that when the position of the hook 22 is to be fine-tuned, the user turns the adjustment knob 7, and the rotation of the threaded sleeve can only drive the worm 51 to rotate, and the worm 51 will drive the worm wheel 52 to rotate, and the worm 51 is coaxially arranged with the connecting gear 53, so that the connecting gear 53 also rotates synchronously, and the rotation of the connecting gear 53 can drive the connecting rack 54 in the sliding groove to achieve lateral movement, and the lateral movement of the connecting rack 54 also synchronously drives the sliding block 21 connected by the connecting rod 6 to move horizontally. It should be noted that in the embodiment of the present application, in order to ensure that the connecting rack 54 can slide in the sliding groove, the length of the sliding groove is greater than the length of the connecting rack 54. In addition, it should be pointed out that the self-locking property of the worm wheel 52 and the worm 51 can effectively ensure the stability of the first connecting module 2 after the adjustment is completed.

[0055] Specifically, refer to Figure 5 and Figure 6 The hanging rod group 42 includes a telescopic rod 421, a first hanging rod 422, a second hanging rod 423 and a third hanging rod 424. The telescopic rod 421 is perpendicular to the board surface of the substrate 1. The first hanging rod 422 is fixedly connected to the connecting block 41. The first hanging rod 422 is horizontally arranged and perpendicular to the telescopic rod 421. The second hanging rod 423 and the third hanging rod 424 are both arranged parallel to the first hanging rod 422. Two telescopic rods 421 are arranged. The two telescopic rods 421 are respectively located at both ends of the first hanging rod 422 and are detachably connected to the connecting block 41. The second hanging rod 423 and the third hanging rod 424 are both slidably connected to the telescopic rod 421.

[0056] The hanging rod group 42 is arranged to be a combination of a telescopic rod 421, a first hanging rod 422, a second hanging rod 423 and a third hanging rod 424, so that the function of the hanging rack of the present application is more complete, the applicability is wider, and it can adapt to items of different sizes. When the second hanging rod 423 and the third hanging rod 424 are close to each other, the entire hanging rod group 42 is in a state of occupying a small space. At this time, items can be placed on the second hanging rod 423 and the third hanging rod 424. When the second hanging rod 423 and the third hanging rod 424 are far away from each other, longer objects can be hung on the second hanging rod 423 and the third hanging rod 424.

[0057] Furthermore, the adjustable hanger rack in the embodiment of the present application also includes a second adjustment component 8, which can adjust the distance between the second hanging rod 423 and the third hanging rod 424 to switch the functional mode of the hanging rod group 42.

[0058] The change in the distance between the second hanging rod 423 and the third hanging rod 424 enables the switching of the functional modes of the hanging rod set 42 .

[0059] Specifically, refer to Figure 7 , Figure 8 The second adjustment component 8 includes a first magnet 81, a second magnet 82, and a third magnet 83. The first magnet 81 is rotatably connected to the telescopic rod 421, the second magnet 82 is fixedly connected to the second hanging rod 423, and the third magnet 83 is fixedly connected to the third hanging rod 424.

[0060] By utilizing the magnetic force between the first magnet 81 and the second magnet 82 and between the first magnet 81 and the third magnet 83, the distance between the second hanging rod 423 and the third hanging rod 424 is changed, thereby effectively changing the tightness between the hanging rods, that is, realizing the switching of functions.

[0061] At the same time, refer to Fig. 9 and Fig.10 A switching block 9 is fixedly connected to the first magnet 81, and the switching block 9 is rotatably connected to the telescopic rod 421. A limiting groove 10 is also provided on the telescopic rod 421. The limiting groove 10 is arranged in a cross shape, and the switching block 9 is arranged in a straight line shape. The switching block 9 can be accommodated in the limiting groove 10.

[0062] The setting of the switching block 9 effectively improves the convenience of switching the modes of the hanging rod group 42.

[0063] Furthermore, two groups of second adjustment components 8 are provided, and the two groups of second adjustment components 8 correspond one to one to the two telescopic rods 421. The stability and load-bearing capacity of the hanging rod group 42 are effectively improved.

[0064] Here, in combination with the above content, how to adjust the second connection module 4 is described. After the second connection module 4 is connected to the first connection module 2, the hanging rod group 42 can be adjusted according to the needs. First, the telescopic rod 421 is telescopic. When the second hanging rod 423 and the third hanging rod 424 need to be close to each other, the telescopic rod 421 is retracted, and then the first magnet 81 is rotated so that one end of the first magnet 81 and the second magnet 82 attract each other, and the other end and the third magnet 83 attract each other. Since the switching component is provided with two groups, the ends of the second hanging rod 423 and the third hanging rod 424 are both attracted by the magnets, making the second hanging rod 423 and the third hanging rod 424 more compact. When the second hanging rod 423 and the third hanging rod 424 need to be farther apart, the telescopic rod 421 is stretched, and then the first magnet 81 is rotated so that one end of the first magnet 81 and the second magnet 82 repel each other, and the other end and the third magnet 83 repel each other. At this time, under the action of this mutually repulsive force, the second hanging rod 423 and the third hanging rod 424 are difficult to get close to each other, thereby ensuring stability when used as a hanging rod.

[0065] It should be noted that the magnetic force of the magnet used in the embodiments of the present application needs to be specifically designed according to the size of the hanging rod and the weight of the product to be hung or carried. This is relatively easy to understand for those skilled in the art, so it is not repeated in the embodiments of the present application.

[0066] Finally, the adjustable hanger frame of the embodiment of the present application further includes a magnetic expansion plate 11, which is fixedly connected to the side of the base plate 1. At the same time, the user can also increase the number of expansion plates according to needs.

[0067] The provision of the expansion board further enhances the applicability of the hanger rack of the present application. Specifically, it can absorb some small warning objects, such as scissors, keys, etc.

[0068] The implementation principle of an adjustable hanger rack in an embodiment of the present application is: the adjustable hanger rack of the present application is set as a combination of a substrate 1, a first connecting module 2, and a second connecting module 4, so that the hanger rack can be adjusted in position, and the modular setting can enable the hanger rack to have multiple functions. When only the first connecting module 2 is used, the main function of the hanger rack is realized by the hook 22. When the second connecting module 4 needs to be used, the main function of the hanger rack is realized by the second connecting module 4. The adjustable hanger rack of the present application effectively improves the applicability and flexibility of the hanger rack.

[0069] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
