Description

Technical Field

[0001] This utility model belongs to the field of fixing device technology, specifically relating to a retractable fixing device. Background Technology

[0002] With the increasing popularity of various mobile devices in daily life, the application of fasteners is becoming more and more widespread. Existing fasteners can be widely used in bicycles, cars, tents, furniture, tools and other portable equipment to achieve stable fixation of various devices.

[0003] However, existing fasteners are usually composed of multiple precision parts, which increases production and assembly costs, makes them structurally complex, increases the failure rate during use, and most fasteners can only be used with specific items. Their operation often requires a certain amount of skill and strength, making them difficult for users to use.

[0004] In addition, many fasteners lack stability after locking and cannot provide sufficient safety, especially when the equipment is subjected to large external forces or vibrations. The fastening mechanism of the fastener is prone to loosening or failure, and cannot effectively ensure the safe fixation of the equipment. Utility Model Content

[0005] In order to overcome the defects of the prior art, the present invention proposes a retractable fixing device, including a locking mechanism and a first connecting fixing member and a second connecting fixing member connected to the locking mechanism;

[0006] The locking mechanism is rotatably provided with a first rotating shaft, and a first constraint band is arranged around the first rotating shaft. The locking mechanism is movably connected to the first connecting fastener through the first constraint band.

[0007] The locking mechanism is further provided with a first locking member. The first rotating shaft is connected to a first limiting member. One end of the first locking member abuts against the internal structure of the locking mechanism through a first elastic member, and the other end of the first locking member abuts against the first limiting member, so as to lock the first rotating shaft based on the force of the first elastic member and the first limiting member.

[0008] Furthermore, a rotational elastic element is connected to one side of the first rotating shaft, the rotational elastic element being used to provide an elastic force that causes the first rotating shaft to rotate in order to retract the first constraint band.

[0009] Preferably, the first limiting member includes a gear arranged around the outside of the first rotating shaft.

[0010] Furthermore, the locking mechanism has a first guide groove, and the first locking member is slidably disposed in the locking mechanism through the first guide groove.

[0011] Specifically, the locking mechanism includes a first side plate and a second side plate, the first rotating shaft is disposed between the first side plate and the second side plate, and the first connecting fastener is connected to the first constraint band on the side of the first side plate away from the second side plate.

[0012] Preferably, the first rotating shaft has an opening and a hollow structure inside. A guide post is provided at the opening of the first rotating shaft. A first inner shaft is coaxially arranged inside the first rotating shaft and rotatably connected to the first side plate and the second side plate. The first constraint band passes through the hollow structure of the first rotating shaft via the guide post.

[0013] Furthermore, the locking mechanism is also rotatably provided with a second rotating shaft, and a second constraint band is provided around the second rotating shaft. The locking mechanism is movably connected to the second connecting fastener through the second constraint band.

[0014] The locking mechanism is further provided with a second locking member. The second rotating shaft is connected to a second limiting member. One end of the second locking member abuts against the internal structure of the locking mechanism through a second elastic member, and the other end of the second locking member abuts against the second limiting member, so as to lock the second rotating shaft based on the force of the second elastic member and the second limiting member.

[0015] Furthermore, the first locking member has a guide opening, and the second locking member passes through the guide opening into the first locking member and abuts against the first locking member through the second elastic member.

[0016] Preferably, the first locking member is connected to a connecting member sleeved on the second rotating shaft, and a second guide groove is provided on the connecting member corresponding to the position of the second locking member, and the second locking member is slidably disposed on the locking mechanism through the second guide groove.

[0017] Preferably, the retractable fixing device further includes a storage shell, which is disposed on the outside of the locking mechanism, and the storage shell is provided with a storage opening corresponding to the positions of the first connecting fixing member and the second connecting fixing member;

[0018] The storage shell has a second outlet corresponding to the first constraint band and a first outlet corresponding to the second constraint band. The first constraint band passes through the first outlet and is connected to the first connecting fastener. The second constraint band passes through the second outlet and is connected to the second connecting fastener.

[0019] This utility model has at least the following beneficial effects:

[0020] The retractable fixing device proposed in this utility model locks the first rotating shaft through the cooperation of the first locking member, the first elastic member, and the first limiting member. The force of the elastic member can maintain the self-locking function of the fixing device, ensuring that the first locking member can firmly abut against the first limiting member, thereby locking the first rotating shaft. This reduces the complex mechanical structure and potential failure points, improves the stability and durability of the system, and the overall structure is compact, easy to carry, maintain and inspect, and is suitable for various occasions such as vehicle transportation that require retractable fixing and position locking.

[0021] Furthermore, the retraction and fixing device proposed in this utility model enables the constraint band to be automatically retracted through the rotation elastic element, which improves the overall ease of use of the device. The gear, as a limiting element that cooperates with the rotating shaft, can provide a precise locking and positioning function. The design of the first guide groove clarifies the movable direction of the first locking element for the user, so that the first locking element can slide more smoothly and prevent locking failure due to jamming or excessive resistance. The rotational connection between the inner shaft and the side plate can effectively reduce friction during rotation. The hollow design and the cooperation with the guide column help guide the first constraint band to maintain the correct trajectory and angle during stretching and retraction.

[0022] Based on this, the locking mechanism also introduces a second rotating shaft and its matching second constraint band, locking component, and limiting component, providing locking mechanisms for the retraction and extension of the constraint bands on both sides, enhancing the flexibility and stability of the system. The design of the guide port on the first locking component and the second guide groove on the rotating connector ensures that the second locking component can slide along a smooth trajectory, and allows users to achieve synchronous locking and unlocking of the two locking components by rotating the rotating connector, making operation more convenient. The storage shell with a storage opening can effectively protect the locking mechanism and each locking component, avoiding the influence of dust and other external substances on the device, facilitating storage and transportation, and extending the equipment's lifespan. The belt outlet on the storage shell can also cooperate to guide the trajectory of the first constraint band.

[0023] Therefore, this utility model proposes a retractable fixing device. The retractable fixing device proposed by this utility model has a simple design and compact structure, which can provide a convenient and flexible user experience. It is simple in structure and easy to operate, and can quickly realize locking and unlocking functions. It provides a relatively flexible and safe fixing method and can be applied to a variety of occasions that require fixing. Attached Figure Description

[0040] Example 1

[0041] Please see Figures 1-5 This embodiment proposes a retractable fixing device, including a locking mechanism 1 and a first connecting fixing member 2 and a second connecting fixing member 3 connected to the locking mechanism 1; the first connecting fixing member 2 and the second connecting fixing member 3 may include, but are not limited to, fixing clips, fixing rings, anchor point mechanisms, hooks, buckles and other components. In this embodiment, the first connecting fixing member 2 and the second connecting fixing member 3 include hooks.

[0042] The locking mechanism 1 is rotatably provided with a first rotating shaft 11, and a first constraint band 111 is arranged around the first rotating shaft 11. The locking mechanism 1 is movably connected to the first connecting fastener 2 through the first constraint band 111.

[0043] The locking mechanism 1 is also movably provided with a first locking member 4, and a first limiting member is connected to the first rotating shaft 11. One end of the first locking member 4 abuts against the internal structure of the locking mechanism 1 through a first elastic member 41, and the other end abuts against the first limiting member. In this embodiment, the first elastic member 41 includes a spring, and the bottom plate 15 of the locking mechanism 1 has a pull hole 151 that is fixedly connected to one end of the spring.

[0044] Specifically, when the first locking member 4 is not subjected to external force but is only subjected to the action of the first elastic member 41 to abut against the first limiting member, the first locking member 4 plays a locking role on the first rotating shaft 11 to prevent the first rotating shaft 11 from rotating in the first clockwise direction, so as to fix the length of the first constraint band 111 stretched by the first connecting fastener 2 driven by the retracting fastener.

[0045] When the first locking member 4 is compressed by the first elastic member 41 by the external force and moves away from the first limiting member, the first locking member 4 releases the locking effect on the first rotating shaft 11, so that the retractable fixing device can stretch the first constraint band 111 through the first connecting fixing member 2 and drive the first rotating shaft 11 to rotate in the first clockwise direction.

[0046] Preferably, the first limiting member includes a first gear 112 disposed around the outside of the first rotating shaft 11, and the first locking member 4 locks the first rotating shaft 11 by abutting against the recess of the first gear 112; in this embodiment, the first gear 112 includes a helical gear with a helical direction facing the first clockwise direction.

[0047] Furthermore, the locking mechanism 1 has a first guide groove 14, and the first locking member 4 is slidably disposed on the locking mechanism 1 through the first guide groove 14. The user can compress the first elastic member 41 by pushing the first locking member 4 in conjunction with the first guide groove 14. In this embodiment, the locking mechanism 1 includes a first side plate 12 and a second side plate 13, and a first rotating shaft 11 is disposed between the first side plate 12 and the second side plate 13.

[0048] Furthermore, a first rotational elastic element 113 is connected to one side of the first rotating shaft 11. The first rotational elastic element 113 is used to provide an elastic force that allows the first rotating shaft 11 to rotate in a second clockwise direction opposite to the first clockwise direction to recover the elastic force of the first constraint band 111. Preferably, the first rotational elastic element 113 is connected to the first rotating shaft 11 on the side of the first side plate 12 away from the second side plate 13. In this embodiment, the first rotational elastic element 113 includes a coil spring.

[0049] Preferably, the first rotating shaft 11 has an opening and a hollow internal structure. A guide post 114 is provided at the opening of the first rotating shaft 11. A first inner shaft 16 is coaxially arranged inside the first rotating shaft 11 and rotatably connected to the first side plate 12 and the second side plate 13, so that the first rotating shaft 11 can rotate relative to the first side plate 12 and the second side plate 13 through the first inner shaft 16. The first constraint band 111 passes through the hollow structure of the first rotating shaft 11 via the guide post 114, so that the guide post 114 can guide the first constraint band 111, thereby ensuring that the first constraint band 111 maintains the correct trajectory and angle during the stretching and retraction process.

[0050] Furthermore, the locking mechanism 1 is also rotatably provided with a second rotating shaft 17, and the second rotating shaft 17 is surrounded by a second constraint band 161. The locking mechanism 1 is movably connected to the second connecting fastener 3 through the second constraint band 161. In a specific embodiment, the second constraint band 161 and the first constraint band 111 belong to the same constraint band.

[0051] Correspondingly, the locking mechanism 1 is also movably provided with a second locking member 5, and the second rotating shaft 17 is connected to a second limiting member. One end of the second locking member 5 abuts against the internal structure of the locking mechanism 1 through a second elastic member 51, and the other end abuts against the second limiting member. In this embodiment, the second elastic member 51 also includes a spring.

[0052] When the second locking member 5 is not subjected to external force but is only subjected to the action of the second elastic member 51 to abut against the second limiting member, the second locking member 5 locks the second rotating shaft 17 to prevent the second rotating shaft 17 from rotating in the second clockwise direction, so as to fix the length of the second constraint band 161 stretched by the second connecting fastener 3 from the retracting fastener.

[0053] When the second locking member 5 is compressed by an external force and moves away from the second limiting member, the second locking member 5 releases its locking effect on the second rotating shaft 17, so that the retractable fixing device can stretch the second constraint band 161 through the second connecting fixing member 3 and drive the second rotating shaft 17 to rotate in the second clockwise direction; correspondingly, the second rotating shaft 17 is also disposed between the first side plate 12 and the second side plate 13.

[0054] Preferably, the second limiting member includes a second gear 162 circumferentially disposed on the outside of the second rotating shaft 17, and the second locking member 5 locks the second rotating shaft 17 by abutting against the recess of the second gear 162. The second locking member 5 has a pressing groove 52 on the side near the second rotating shaft 17, and the user can compress the second elastic member 51 by pressing the pressing groove 52. In this embodiment, the second gear 162 includes a helical gear with a helical direction facing the second clockwise direction.

[0055] Preferably, in this embodiment, the first locking member 4 has a guide opening 42, the second locking member 5 passes through the guide opening 42 and abuts against the first locking member 4 through the second elastic member 51, the first locking member 4 is connected to a rotating connector 44 sleeved on the second rotating shaft 17, the rotating connector 44 has a second guide groove 43 at the position corresponding to the second locking member 5, and the second locking member 5 is slidably disposed on the locking mechanism 1 through the second guide groove 43;

[0056] Therefore, when the user rotates the rotating connector 44 around the second rotating shaft 17 away from the locking mechanism 1 by the first locking member 4, the locking of the first locking member 4 to the first rotating shaft 11 and the locking of the second locking member 5 to the second rotating shaft 17 will be released simultaneously.

[0057] When the user rotates the rotating connector 44 around the second rotating shaft 17 toward the locking mechanism 1 via the first locking member 4, the locking of the first rotating shaft 11 by the first locking member 4 and the locking of the second rotating shaft 17 by the second locking member 5 will be realized simultaneously.

[0058] Furthermore, a second rotational elastic element 163 is connected to one side of the second rotating shaft 17. The second rotational elastic element 163 is used to provide an elastic force that allows the second rotating shaft 17 to rotate in the first clockwise direction to retract the second constraint band 161. Preferably, the second rotational elastic element 163 is connected to the second rotating shaft 17 on the side of the second side plate 13 away from the first side plate 12. In this embodiment, the second rotational elastic element 163 also includes a coil spring.

[0059] Correspondingly, the second rotating shaft 17 also has an opening and a hollow internal structure. A guide post 114 is provided at the opening of the second rotating shaft 17. A second inner shaft 18 is coaxially arranged inside the second rotating shaft 17 and rotatably connected to the first side plate 12 and the second side plate 13, so that the second rotating shaft 17 can rotate relative to the first side plate 12 and the second side plate 13 through the second inner shaft 18. The second constraint band 161 passes through the hollow structure of the second rotating shaft 17 via the guide post 114, so that the guide post 114 can guide the second constraint band 161, thereby ensuring that the second constraint band 161 maintains the correct trajectory and angle during the stretching and retraction process.

[0060] Preferably, the retractable fastener further includes a storage shell 6 for storing the first connecting fastener 2 and the second connecting fastener 3. The storage shell 6 is disposed on the outside of the locking mechanism 1, and the storage shell 6 is provided with a storage opening 61 corresponding to the positions of the first connecting fastener 2 and the second connecting fastener 3. The first connecting fastener 2 and the first rotary elastic member 113 are both stored in the storage shell 6 on the side of the first side plate 12 away from the second side plate 13, while the second connecting fastener 3 and the second rotary elastic member 163 are both stored in the storage shell 6 on the side of the second side plate 13 away from the first side plate 12.

[0061] The storage shell 6 is also provided with a first strap outlet 62 and a second strap outlet 63 corresponding to the first constraint strap 111 and the second constraint strap 161, respectively. The first constraint strap 111 passes through the first strap outlet 62 and is connected to the first connecting fastener 2. The second constraint strap 161 passes through the second strap outlet 63 and is connected to the second connecting fastener 3.

[0062] Preferably, the locking mechanism 1 can be connected to multiple first connecting fasteners 2 and second connecting fasteners 3 to further enhance the fixing effect of the retractable fastener proposed in this embodiment from multiple different directions.

[0063] In summary, this utility model proposes a retractable fixing device. The retractable fixing device proposed by this utility model has a simple design and compact structure, which can provide a convenient and flexible user experience. It is simple in structure and easy to operate, and can quickly realize locking and unlocking functions. It provides a relatively flexible and safe fixing method and can be applied to a variety of occasions that require fixing.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
