[0002] In daily life, fasteners, as basic components for connecting various portable items, have long been deeply integrated into our usage scenarios. Taking wheelchair travel as an example, to solve the problem of where to put items like water bottles and bags while traveling, many users often install one fastener on the wheelchair backrest and another on the water bottle, bag, etc. With the two fasteners working together, items like water bottles and bags can be easily secured to the wheelchair backrest, avoiding the inconvenience of holding items and improving travel convenience. However, existing fasteners are installed through sewing and fasteners, and the actual stress on the fasteners is concentrated in a small area around the sewing stitches and fastener contact points. With increased usage, the water bottle, bag, etc., connected to the fastener will experience continuous tension, which can easily cause the fastener to fall off over time, failing to meet long-term, stable usage needs. Utility Model Content

Detailed Implementation

[0023] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation on the present invention.

[0024] like Figures 1-6As shown, a hanging lock includes a first plate 10 and a second plate 20. A first end of the first plate 10 is rotatably connected to a first end of the second plate 20, allowing the first plate 10 to rotate relative to the second plate 20. A clamping space 30 for clamping flat items is formed between the first plate 10 and the second plate 20. A locking tongue 11 protruding from the surface of the first plate 10 is provided on the first plate 10. The locking tongue 11 is used to detachably engage with an external structure, thus facilitating the hanging of items on flat objects, such as water bottles or storage bags on the back of a wheelchair.

[0025] Furthermore, the number of latches 11 is not limited, but is at least one. In some embodiments, multiple latches 11 are arranged in a straight line, parallel to the length direction of the first plate 10; in other embodiments, multiple latches 11 are arranged in a straight line, perpendicular to the length direction of the first plate 10; and in still other embodiments, multiple latches 11 are not arranged in a straight line. This invention does not limit the number or positional relationship of the latches 11. In this example, there are two latches 11, arranged in a straight line, perpendicular to the length direction of the first plate 10.

[0026] Furthermore, the first plate 10 is provided with a first magnetic element. The first magnetic element and the external mating structure attract each other in the direction of achieving a detachable engagement, thereby enabling quick engagement between the hook-and-loop latch and the external mating structure. The number of the first magnetic elements is consistent with the number of the latches 11, and each first magnetic element has a corresponding latch 11. Furthermore, each latch 11 is provided with a magnet slot, and each magnet slot contains a first magnetic element. Even further, when multiple first magnetic elements exist, the magnetic poles of all the first magnetic elements point in the same direction, and the N poles of all the first magnetic elements point in the same direction.

[0027] Furthermore, to enhance the connection between the hanging buckle and the strip-shaped item, the first plate 10 is provided with a first fixing hole 12, and the second plate 20 is provided with a second fixing hole 21. The first fixing hole 12 and the second fixing hole 21 correspond to each other and are used to insert fasteners to fix the first plate 10 and the second plate 20 together, thereby maintaining the clamping state of the clamping space 30 and fixing the hanging buckle and the flat item. The fasteners can be bolts, locking pins, or other components that can restrict the opening of the first and second plates.

[0028] Furthermore, the number of the first fixing hole 12 and the second fixing hole 21 is not limited. The first plate 10 is provided with at least one first fixing hole 12, and the second plate 20 is provided with at least one second fixing hole 21. Preferably, the number of the first fixing holes 12 is consistent with the number of the second fixing holes 21, and any first fixing hole 12 can be matched with a corresponding second fixing hole 21 on the second plate 20. By having the fastener pass through the corresponding first fixing holes 12 and second fixing holes 21, not only can the first plate 10 and the second plate 20 be rigidly locked together, preventing relative sliding and clamping failure of the first plate 10 and the second plate 20 due to vibration or external force, but also, by having the fastener pass through the flat object, it can be ensured that the hanging buckle will not fall off the flat object.

[0029] Furthermore, in some embodiments, to further strengthen the connection between the hook lock and the flat object, the first end of the hook lock is provided with a hook portion 14, which is used to hook onto the edge of the flat object. The hook portion 14 helps to securely fix the hook lock to the flat object. When the first and second plates accidentally detach and fail to be securely clamped to the flat object, the hook portion 14 will hook onto the top of the flat object under the action of gravity, preventing the hook lock from falling off. In addition, the hook portion 14 can also increase the force-bearing area between the hook lock and the flat object to balance the force. The number of hook portions 14 is not limited, but there is at least one. Preferably, when there are multiple hook portions 14, the multiple hook portions 14 should be at the same horizontal height.

[0030] Furthermore, in some examples, the hook portion 14 is provided on the first plate 10, located at the first end of the first plate 10. The hook portion 14 faces the second plate 20 and extends in a direction away from the connection between the first plate 10 and the second plate 20, thereby forming a hook shape. Furthermore, in order to ensure that the hook portion 14 can fully abut against the edge of the flat object, the second plate 20 is provided with a clearance position 23 corresponding to the hook portion 14. When the first plate 10 and the second plate 20 are parallel to each other, the hook portion 14 is partially located within the clearance position 23 and partially protrudes from the surface of the second plate 20. This allows the hook portion 14 to be fully hooked onto the edge of the flat object as long as it can enter the clamping space 30, preventing the hook portion 14 from detaching from the edge of the flat object, thereby improving the stability of the hanging and ensuring balanced force distribution.

[0031] Furthermore, in other examples, the hook portion 14 is provided on the second plate 20, located at the first end of the second plate 20. The hook portion 14 extends toward the first plate 10 and in a direction away from the connection between the first plate 10 and the second plate 20, thereby forming a hook shape. Further, in order to ensure that the hook portion 14 can fully abut against the edge of the flat object, the first plate 10 is provided with a clearance position 23 corresponding to the hook portion 14. When the first plate 10 and the second plate 20 are parallel to each other, the hook portion 14 is partially located within the clearance position 23 and partially protrudes from the surface of the first plate 10. This allows the hook portion 14 to be fully hooked onto the edge of the flat object as long as it can enter the clamping space 30, preventing the hook portion 14 from detaching from the edge of the flat object, thereby improving the stability of the hanging and ensuring balanced force distribution.

[0032] In some examples, both the first end of the first plate 10 and the first end of the second plate 20 are provided with the hook portion 14, and both the second plate 20 and the first plate 10 are provided with the clearance position 23 corresponding to the hook portion 14. When the first plate 10 and the second plate 20 are parallel, the hook portion 14 is partially located within the clearance position 23. This makes it easier for the hook portion 14 to hook onto the top edge of a flat object, preventing the hook portion 14 from detaching from the edge of the flat object.

[0033] Furthermore, in order to fully utilize the function of the hook portion 14, the horizontal height of the hook portion 14 during use is not higher than the horizontal height of the connection portion between the first plate 10 and the second plate 20.

[0034] Furthermore, to further enhance the stability of the hook-and-loop fastener with the flat object, anti-slip teeth 13 are provided on the side of the first plate 10 facing the second plate 20 and / or the side of the second plate 20 facing the first plate 10. The anti-slip teeth 13 are used to enhance the frictional resistance to the flat object. In some examples, the anti-slip teeth 13 are provided on the side of the first plate 10 facing the second plate 20, while the side of the second plate 20 facing the first plate 10 does not have the anti-slip teeth 13. In other examples, the anti-slip teeth 13 are provided on the side of the second plate 20 facing the first plate 10, while the side of the first plate 10 facing the second plate 20 does not have the anti-slip teeth 13. In still other examples, anti-slip teeth 13 are provided on both the side of the first plate 10 facing the second plate 20 and the side of the second plate 20 facing the first plate 10. Preferably, anti-slip teeth 13 are provided on both the side of the first plate 10 facing the second plate 20 and the side of the second plate 20 facing the first plate 10. Further, the shape of the anti-slip teeth 13 is not limited, but preferably the free end is dot-shaped or linear. In this embodiment, the free end of the anti-slip teeth 13 is linear, and the cross-sectional shape is triangular. The number and distribution of the anti-slip teeth 13 are not limited; in this example, the anti-slip teeth 13 are arranged in multiple rows symmetrically.

[0035] Furthermore, to facilitate the engagement of the hook-and-loop latch with the external mating structure, the surface where the latch 11 is located is opposite to the side of the first plate 10 facing the second plate 20. In other words, the latch 11 is located on the surface of the first plate 10 opposite to the second plate 20.

[0036] Furthermore, to achieve a rotatable connection between the first plate 10 and the second plate 20 and to simplify the installation structure, one of the first plate 10 and the second plate 20 has a first connecting portion 15 spaced apart from each other at its first end, and the other has a second connecting portion 22 spaced apart from each other at its first end. The first connecting portion 15 is provided with a connecting hole 151, and the second connecting portion 22 is provided with a connecting shaft 221. The connecting shaft 221 can be inserted into the connecting hole 151 by pressing the first connecting portion, and the connecting shaft 221 can rotate within the connecting hole 151. In this example, the first connecting part 15 is located at the first end of the first plate 10, and the second connecting part 22 is located at the first end of the second plate 20. The first plate 10 is provided with two first connecting parts 15, each of which is provided with a connecting hole 151. The two first connecting parts 15 are arranged side by side in a horizontal first direction, and the two connecting holes 151 are located on the same straight line. The second plate 20 is provided with two second connecting parts 22, which are arranged side by side in a horizontal first direction. Each second connecting part 22 is provided with a connecting shaft 221. The connecting shaft 221 is located at the end of the second connecting part 22 away from the other second connecting part 22, and the two connecting shafts 221 are respectively inserted into the two connecting holes 151.

[0037] The first connecting portions 15 are spaced apart from each other, so they can be squeezed and slightly deformed to facilitate the insertion of the connecting shaft 221 into the connecting hole 151.

[0038] The second connecting portions 22 are spaced apart from each other, so they can be squeezed and slightly deformed to facilitate the insertion of the connecting shaft 221 into the connecting hole 151.

[0039] Furthermore, for ease of installation, the free end of the connecting shaft 221 is provided with a guide portion 2211, which is constructed as an inclined surface and is formed by the end face of the connecting shaft 221 tilting inward.

[0040] Correspondingly, the first connecting portion 15 is provided with an inlet groove 152, which communicates with the connecting hole 151 in a direction transverse to the axial direction of the connecting hole 151, and extends through the ends of the first connecting portion 15 in a direction facing each other. The connecting shaft 221 can enter the inlet groove 152 through the guide portion 2211, and can enter the connecting hole 151 by squeezing the inlet groove 152, thereby forming a rotational connection between the first connecting portion 15 and the second connecting portion 22. Specifically, the inclined surface of the guide portion 2211 facilitates the initial entry of the guide portion 2211 into the inlet groove 152; with the user's continuous force, the connecting shaft 221 can squeeze the wall of the inlet groove 152 and be forced from the inlet groove 152 into the connecting hole 151. During this process, the first connecting portion 15 and the second connecting portion 22 can undergo corresponding deformation to adapt to the current squeezing. When the connecting shaft 221 enters the connecting hole 151, the first connecting part 15 and the second connecting part 22 return to their default shapes, and the connecting shaft 221 is restricted in the connecting hole 151 and cannot come out, thus forming a rotating connection so that the first plate 10 and the second plate 20 can rotate relative to each other.

[0041] In the default state, the distance between the ends of the connecting shaft 221 is greater than the distance between the end faces of the inlet groove 152. In this way, when the connecting shaft 221 is squeezed into the connecting hole 151, it is not easy to retract into the inlet groove 152.

[0042] Furthermore, the guide groove 152 is provided with a guide surface, which is inclined relative to the direction in which the connecting shaft 221 enters the guide groove 152, and forms a flared structure. That is, the distance between the ends of the guide surfaces near the connecting hole 151 is less than the distance between the ends of the guide surfaces away from the connecting hole 151.

[0043] The inlet surface and the guide portion 2211 can fit together, thereby facilitating the entry of the connecting shaft 221 into the inlet groove 152 and pressing the first connecting portion 15.

[0044] Furthermore, in the horizontal direction, the maximum distance between the guide portion 2211 and the guide portion 2211 of the other connecting shaft 221 is greater than the minimum distance between the inlet surface and the inlet surface of the other first connecting portion 15; the minimum distance between the guide portion 2211 and the guide portion 2211 of the other connecting shaft 221 is not greater than the maximum distance between the inlet surface and the inlet surface of the other first connecting portion 15. In this way, the connecting shaft 221 can quickly enter the inlet groove 152 through the guide portion 2211 and be squeezed into the connecting hole 151. During installation, through the cooperation of the guide portion 2211 and the inlet surface, that is, by fitting the guide portion 2211 and the inlet surface together, and then squeezing the connecting shaft 221 closer and closer to the connecting hole 151, the connecting shaft 221 is finally able to enter the connecting hole 151. Furthermore, during the process of the connecting shaft 221 entering the connecting hole 151, the first connecting part 15 and / or the second connecting part 22 deform under the squeezing action of the connecting shaft 221 and the guide groove 151, so as to facilitate the connecting shaft 221 entering the connecting hole 151. Specifically, the deformation is such that the distance between the two first connecting parts 15 increases, or the distance between the two second connecting parts 22 decreases, or both of the above deformations exist simultaneously. After the connecting shaft 221 is fully entered into the connecting hole 151, the first connecting part 15 and / or the second connecting part 22 return to the position before the deformation, so that the connecting shaft 221 can pass through the connecting hole 151.

[0045] In use, the first plate 10 and the second plate 20 are opened to increase the clamping space 30. Then, the first plate 10 and the second plate 20 are placed on both sides of a flat object, such as the sides of a wheelchair backrest. Next, the first plate 10 and the second plate 20 are clamped so that the anti-slip teeth 13 are in full contact with the flat object, increasing the connection between the hanging lock and the flat object and achieving initial fixation. Then, through the cooperation of the first fixing hole 12, the second fixing hole 21 and the fastener, the first plate 10, the second plate 20 and the flat object are firmly combined together, thereby realizing the combination of the hanging lock and the flat object, for example, fixing the hanging lock to both sides of the wheelchair backrest.

[0046] Although the present invention has been disclosed through the above embodiments, the scope of the present invention is not limited thereto. Without departing from the concept of the present invention, the above components can be replaced by similar or equivalent elements known to those skilled in the art.
