[0002] Bicycles, as a green and environmentally friendly means of transportation, are powered by pedals and are loved by the public. More and more people use bicycles as fitness equipment for exercise. When bicycles are not in use, people hang them on the wall using bicycle racks to save space.

[0003] Currently, wall-mounted bicycle racks typically consist of a wall panel, a connecting plate, and two support arms. The wall panel is connected to the connecting plate via pins, and the support arms are attached to the outside of the connecting plate. The support arms have a hollow structure in the middle for hanging the bicycle tire. After the user stands the bicycle upright, they insert the front wheel into the middle of the support arm to achieve vertical placement of the bicycle, thus saving space.

[0004] However, these types of bike mounts have the following drawbacks: 1. Using the groove in the middle of the support arm for balance does not effectively secure the bicycle, causing it to frequently tilt left and right and become unstable. 2. Currently available wall-mounted bike mounts generally have V-shaped grooves at the ends of the support arms, but the size of these grooves is limited and cannot accommodate bicycles with mudguards. When the gap between the mudguard and the tire is small, the end of the support arm may interfere with the mudguard, affecting normal use. Utility Model Content

[0044] It should be noted that all directionality indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directionality indications will also change accordingly.

[0045] As shown in Figures 1 to 6 The utility model provides a bicycle hanger, which comprises:

[0046] A wall plate 10 is adapted to be installed on a wall and serves as an installation structure of the bicycle hanger.

[0047] A connecting frame 20 is connected to the wall plate 10, and the connecting frame 20 is provided with an installation cavity 21.

[0048] A positioning device is connected to the connecting frame 20 and serves to support and limit the bicycle wheel.

[0049] Two clamping plates 30 are provided, one end of each clamping plate 30 extends into the installation cavity 21 through the open end of the installation cavity 21 and is rotatably connected to the connecting frame 20, the other end of each clamping plate 30 extends out of the opening of the installation cavity 21, and a first clamping passage 31 is formed between the two clamping plates 30, which is adapted to accommodate part of the bicycle tire.

[0051] It is worth mentioning that the wall plate 10 and the connecting frame 20 are rotatably connected, and when the front tire of the bicycle is clamped between the two clamping plates 30, the angle between the bicycle and the wall can be adjusted through the rotational cooperation between the wall plate 10 and the connecting frame 20, so as to shorten the length of the bicycle extending outward when the bicycle is hung on the wall, reduce the probability of collision between other objects and the bicycle or between people and the bicycle, and improve the safety of bicycle storage.

[0052] It is further pointed out that the wallboard 10 and the connecting frame 20 are connected through the pin shaft, the wallboard 10 is provided with a first connecting plate 11 at each end, and a first plug-in hole 111 is arranged on each first connecting plate 11, the connecting frame 20 is provided with a second connecting plate 24 at each end, and a second plug-in hole 241 is arranged on each second connecting plate 24, when the wallboard 10 is connected with the connecting frame 20, the connecting frame 20 is inserted between the two first connecting plates 11, and the two second connecting plates 24 are respectively attached to the corresponding first connecting plates 11, wherein the two first connecting plates 11 and the two second connecting plates 24 are connected through the rotating assembly 100.

[0053] It is further pointed out that the rotating assembly 100 includes a flat pad 110, a spring pad 120, a screw 130, and a plug 140, and the number of flat pads 110 is two, which are located on the upper and lower sides of the first connecting plate 11, the screw 130 and the plug 140 are also located on the upper and lower sides of the first connecting plate 11, wherein the rotating connection between the wallboard 10 and the connecting frame 20 is completed through the connection between the screw 130 and the plug 140.

[0054] Preferably, one side of the two clamping plates 30 located in the mounting cavity 21 is connected through the linkage part 40, when the bicycle tire is inserted or pulled out of the first clamping channel 31, the two clamping plates 30 are driven to open and close synchronously through the linkage part 40.

[0055] It is further pointed out that the linkage part 40 includes at least two linkage plates 41, and the two linkage plates 41 are respectively installed on the side of the two clamping plates 30 located in the mounting cavity 21, wherein the opposite sides of the two linkage plates 41 are provided with teeth 411, and the synchronous opening and closing of the two clamping plates 30 are driven by the meshing between the teeth 411 on the two linkage plates 41.

[0056] In this embodiment, by setting the linkage part 40, the two clamping plates 30 can be synchronously opened and closed under the action of the linkage part 40, ensuring that the bicycle tire clamped between the two clamping plates 30 is always in the central position without tilting, thereby improving the reliability of the bicycle storage.

[0057] It is worth mentioning that in order to ensure the reliability of the meshing between the two linkage plates 41, and the positioning structure is arranged between the linkage plate 41 and the corresponding clamping plate 30, wherein the positioning structure includes a convex part 42 arranged on the linkage plate 41, and a concave part 32 arranged on the clamping plate 30, the positioning connection between the linkage plate 41 and the clamping plate 30 is realized through the concave-convex cooperation between the convex part 42 and the concave part 32.

[0058] The position of the convex part 42 and the concave part 32 can be interchanged, that is, the concave part 32 is arranged on the linkage plate 41, and the convex part 42 is arranged on the clamping plate 30. In addition, in order to ensure the reliability of the positioning between the linkage plate 41 and the clamping plate 30, two convex parts 42 can be arranged on the linkage plate 41, and the two convex parts 42 are located on both sides of the locking position of the linkage plate 41 and the clamping plate 30, and two corresponding concave parts 32 are also arranged on the clamping plate 30, and the two concave parts 32 are also located on both sides of the locking position of the linkage plate 41 and the clamping plate 30.

[0059] Preferably, a reset assembly 50 is further arranged between the connecting frame 20 and the clamping plate 30, and the reset assembly 50 comprises at least one elastic member, which is used to drive the clamping plate 30 to return to the initial position. When the bicycle wheel is hung on the positioning device, the bicycle wheel presses the clamping plate 30, and the clamping plate 30 presses the elastic member. Since the forces are mutual, the elastic member provides a pressing force to the bicycle wheel for the clamping plate 30, thereby realizing the compression of the bicycle wheel. The elastic member can be a spring, a spring piece or a torsion spring.

[0060] It is further pointed out that the elastic member is a torsion spring 52, the reset assembly 50 further comprises a sleeve 51 connected with the clamping plate 30, and the torsion spring 52 is sleeved on the sleeve 51. The central axis direction of the torsion spring 52 is parallel to the rotating axis direction of the clamping plate 30, and the two ends of the torsion spring 52 are in contact with the clamping plate 30 and the connecting frame 20, respectively.

[0061] In the embodiment, by arranging the reset assembly 50, when the bicycle tire is clamped between the two clamping plates 30, on the one hand, the clamping force of the two clamping plates 30 on the bicycle tire can be improved, and the shaking of the bicycle can be avoided, and on the other hand, when the bicycle is taken off from the bicycle rack, the two clamping plates 30 can return to the initial state.

[0062] It is worth mentioning that in order to ensure that the two clamping plates 30 can be opened and closed synchronously under the action of the linkage plate 41, and the clamping force can be improved and returned to the initial state under the action of the reset assembly 50, one linkage plate 41 and one reset assembly 50 are arranged at the upper and lower ends of each clamping plate 30, respectively. In order to simplify the connection structure among the linkage plate 41, the clamping plate 30 and the reset assembly 50, a single long screw rod can be used to realize the connection among them. That is, the long screw rod passes through the linkage plate 41 and the clamping plate 30 from top to bottom in sequence, and is screwed with the sleeve.

[0063] Preferably, the connecting frame 20 comprises support plates 22 located at both sides of the opening end of the mounting cavity 21, and a bottom plate 23 used to connect the two support plates 22, the number of the bottom plate 23 is two, and the bottom plate 23 is located at the upper and lower ends of the support plate 22 respectively, wherein, one side of the bottom plate 23 extends in the direction away from the cavity opening of the mounting cavity 21 to form a second connecting plate 24, the other side of the bottom plate 23 extends in the direction away from the cavity opening of the mounting cavity 21 to form a third connecting plate 25, and the third connecting plate 25 serves as the connecting position of the clamping plate 30.

[0064] It is further pointed out that the third connecting plate 25 is arranged in an L shape, one side of the third connecting plate 25 connected with the bottom plate 23 serves as the connecting position of the clamping plate 30, and the other side of the third connecting plate 25 is a free end, wherein, the connecting frame 20 further comprises a cover plate 26, and both ends of the cover plate 26 are connected to the free end of the corresponding third connecting plate 25 through fasteners.

[0065] In the embodiment, by arranging the cover plate 26, on the one hand, the connecting position between the clamping plate 30 and the linkage plate 41 and the reset assembly 50 can be hidden, and the appearance of the whole bicycle rack is improved, on the other hand, the cover plate 26 is used to realize the "sealing" of the cavity bottom of the accommodating cavity, so that when the bicycle tire is inserted between the two clamping plates 30, the depth of the bicycle tire inserted can be limited, and the wall will not be scratched, and the neatness of the wall is ensured.

[0066] Optionally, the positioning device comprises a V-shaped piece 82 and two movable plates 60 arranged in parallel with each other. The first end of each of the two movable plates 60 is connected with the connecting frame 20, and the two ends of the V-shaped piece 82 are connected with the second end of each of the two movable plates 60 respectively. In this way, a strip-shaped hole is formed between the two movable plates 60 arranged in parallel with each other, and the wheel of the bicycle can be clamped into the strip-shaped hole to form a support for the wheel of the bicycle.

[0067] On the basis of the above embodiment, the two ends of the V-shaped piece 82 are rotatably connected with the second end of each of the two movable plates 60. In this way, when the bicycle has a mudguard, the V-shaped piece 82 is prevented from interfering with the mudguard.

[0068] Preferably, the positioning device comprises movable plates 60 arranged at both sides of the opening end of the mounting cavity 21, and one end of each of the two movable plates 60 is movably connected with the connecting frame 20, so that the movable plate 60 can rotate relative to the connecting frame 20, wherein, a buffer portion 70 is arranged at the connection between the movable plate 60 and the connecting frame 20, and the buffer portion 70 can rotate synchronously with the rotation of the movable plate 60.

[0069] Further preferably, the buffer part 70 comprises two buffer blocks 71, and each support plate 22 is clamped between the corresponding movable plate 60 and the buffer block 71, wherein the buffer block 71 is synchronously rotated by the rotation of the movable plate 60, so that the end of the buffer block 71 abuts against the bottom plate 23.

[0070] It is worth mentioning that when the bicycle tire is clamped between the two clamping plates 30, in order to prevent the bicycle from falling, a supporting structure capable of supporting the bottom is arranged below the bicycle tire, but the supporting structure capable of supporting the bottom cannot affect the free placement and taking of the bicycle, so the movable plate 60 and the connecting frame 20 are rotationally connected, thereby facilitating the placement and taking of the bicycle. Although the movable connection facilitates the placement and taking of the bicycle, the movable connection can cause the movable plate 60 to automatically turn down under the action of gravity, affecting the reliability of the supporting bottom. Therefore, the buffer part 70 is arranged between the movable plate 60 and the connecting frame 20, which on the one hand plays a buffering role when the movable plate 60 is turned down, avoiding the direct impact of the screw connected with the movable plate 60 on the bottom of the first arc-shaped guide groove 222 during the rotation of the movable plate 60, thereby reducing noise and wear; on the other hand, when the buffer part 70 abuts against the bottom plate 23, it can block the further turning down of the movable plate 60, thereby improving the supporting bottom of the bicycle in the storage state.

[0071] It is further pointed out that one end of the movable plate 60 is provided with two first connecting holes 61, the support plate 22 is provided with a second connecting hole 221 and a first arc-shaped guide groove 222, and the buffer block 71 is provided with two third connecting holes 711, wherein one of the first connecting holes 61 is connected with one of the third connecting holes 711 through the second connecting hole 221 and a fastener, and the other first connecting hole 61 is connected with the other third connecting hole 711 through the first arc-shaped guide groove 222 and a fastener.

[0072] Preferably, the positioning device further comprises an adjusting part 80, and the other end of each movable plate 60 is connected with the adjusting part 80. The adjusting part 80 comprises two adjusting plates 81, and each adjusting plate 81 is detachably connected with the corresponding movable plate 60, so that the adjusting part 80 can be movably assembled along the length direction of the movable plate 60.

[0073] It is further pointed out that the movable plate 60 is provided with at least two first adjusting holes 62, and the adjusting plate 81 is provided with a plurality of second adjusting holes 811. The relative distance between the two first adjusting holes 62 is equal to the relative distance between any two adjacent second adjusting holes 811. By connecting the two first adjusting holes 62 with the corresponding two second adjusting holes 811, the relative position between the movable plate 60 and the adjusting plate 81 is changed.

[0074] In the embodiment, by setting the adjusting plate 81, the total length of the movable plate 60 and the adjusting plate 81 is changed according to the connecting position between the first adjusting hole 62 and the second adjusting hole 811, thereby adapting to the storage of bicycles with different size tires, and improving the flexibility of the bicycle hanger.

[0075] Preferably, the adjusting part 80 further comprises a V-shaped piece 82, and the two ends of the V-shaped piece 82 are respectively rotatably connected to the two adjusting plates 81, wherein the two sides of the open end of the V-shaped piece 82 are respectively provided with two fourth connecting holes 821, the adjusting plate 81 is provided with a fifth connecting hole 812 and a second arc-shaped guide slot 813, and one of the fourth connecting holes 821 is connected to the fifth connecting hole 812 through a fastener, and the other fourth connecting hole 821 is connected to the second arc-shaped guide slot 813 through a fastener.

[0076] In the embodiment, by setting the thin V-shaped piece 82, and rotatably connecting the V-shaped piece 82 and the adjusting plate 81, if the bicycle has a mudguard, when the bicycle tire is inserted between the two clamping plates 30, the V-shaped piece 82 can be inserted between the tire and the mudguard, and interference phenomenon will not occur due to the existence of the mudguard, and the tire of the bicycle can be supported through the V-shaped piece 82.

[0077] Preferably, the bicycle hanger further comprises a lower support 90 mounted on a wall, and the lower support 90 is provided with a second clamping channel 91, wherein the second clamping channel 91 and the first clamping channel 31 are parallel in the vertical direction.

[0078] In other embodiments, the positioning device comprises two clamping jaws, and the wheel of the bicycle can be clamped by the clamping jaws; in other embodiments, the positioning device can further comprise a hook, and the wheel of the bicycle can be hung on the hook.
