Description

Technical Field

[0001] The present invention relates to the technical field of buttons, and more particularly to a button. Background Art

[0002] At present, nursing clothes face some problems when providing care for special groups such as the disabled and demented. Traditional fastening devices are often simple in structure and can be easily unfastened unconsciously by the disabled and demented, resulting in a high risk of involuntary undressing, and cannot effectively guarantee the safety and protection of nursing clothes. For example, some common buttons, zippers, etc. may be pulled or unfastened by the user's unconscious actions. For people who need special care, this may not only cause them to catch a cold, but also cause some safety hazards, such as accidental exposure of the body, etc., which brings many inconveniences to nursing work and cannot meet the high requirements of functional nursing clothes in terms of safety protection.

[0003] Based on this, we provide a mechanism buckle. Summary of the invention

[0004] In order to solve the problems raised in the above-mentioned background technology, the present invention provides a mechanism buckle, which improves the safety protection effectiveness of functional nursing clothing. The double-action unlocking mechanism is combined with the staggered locking principle of the J-shaped rod and the horizontal bar. While ensuring that nursing staff can quickly complete the buckling / unbuttoning operation, it makes it difficult for disabled and demented people to trigger the unbuttoning through a single action or unconscious behavior, effectively preventing the risk of involuntary undressing.

[0005] The present invention provides a mechanism buckle adopting the following technical solution:

[0006] A mechanism buckle comprises a sub-buckle, a mother buckle and a locking mechanism, wherein the locking mechanism is arranged inside the sub-buckle; the mother buckle comprises a round sleeve, wherein a pair of cross bars are arranged inside the round sleeve; the sub-buckle comprises a circular disk, wherein an inner sleeve is arranged at the bottom of the circular disk, an outer sleeve is slidably arranged at the bottom of the inner sleeve, and a spring is arranged between the outer sleeve and the circular disk; the locking mechanism comprises two J-shaped rods arranged at the bottom of the circular disk, and the bending areas of the two J-shaped rods are arranged at the bottom of the outer sleeve.

[0007] By adopting the above technical solutions, the safety protection effectiveness of functional nursing clothing is improved. The double-action unlocking mechanism is combined with the offset locking principle of the J-shaped rod and the horizontal bar. While ensuring that nursing staff can quickly complete the fastening / unfastening operations, it makes it difficult for disabled and demented people to trigger unfastening through a single action or unconscious behavior, effectively preventing the risk of involuntary undressing.

[0008] Preferably, the locking mechanism comprises a movable disk arranged on the top of the circular disk, and the two J-shaped rods are both rotatably arranged on the bottom of the movable disk through torsion springs.

[0009] By adopting the above technical solution, the stability and firmness of the hook lock in this design are enhanced. At the same time, the force storage and release process of the torsion spring is smooth and powerful, which reduces mechanical wear and extends the service life of the mechanism buckle.

[0010] Preferably, anti-slip grooves are provided on the top of the moving plate.

[0011] Preferably, the locking mechanism further comprises two track grooves formed on the inner wall of the disc, wherein sliders are slidably arranged inside the two track grooves, and the sliders are fixedly connected to the bottom of the moving disc via vertical pads.

[0012] By adopting the above technical solution, the track groove and the slider limit the rotation range of the moving plate on the disc, avoiding the mechanism from being stuck due to excessive rotation, ensuring the one-time success rate of the operation, and a stepped damping feeling is generated when the slider slides through the track groove. The operator can sense the progress of the unbuttoning without visual observation, and the traditional two-handed operation is simplified to a single-hand thumb pressing and rotating compound action, so that the nursing staff can complete the unbuttoning faster.

[0013] Preferably, an arc-shaped groove is formed on the inner wall of the track groove, an arc-shaped tension spring is arranged inside the arc-shaped groove, one end of the arc-shaped tension spring is fixedly connected to the arc-shaped groove, and the other end of the arc-shaped tension spring is fixedly connected to the slider.

[0014] Preferably, a first magnet is disposed on the side of the slider, and a second magnet is disposed on the side of the track groove away from the slider, and the magnetic poles of the first magnet and the second magnet are different.

[0015] Preferably, the attraction force between the first magnet and the second magnet after contact is smaller than the elastic force of the arc-shaped tension spring.

[0016] By adopting the above technical solution, it is convenient for workers to quickly complete one-handed unbuttoning and one-handed buckling, and ensure the consistency of the position of the J-shaped rod during use.

[0017] Preferably, the outer edges of the sub-button and the mother-button are both rounded.

[0018] Preferably, both the sub-button and the main button are provided with sewing holes.

[0019] In summary, the present invention includes the following beneficial technical effects:

[0020] 1. The unlocking and locking are completed by fastening the sub-button and the main button and locking the two J-shaped rods and two horizontal bars. This structural design improves the safety protection performance of the functional nursing clothing. The double-action unlocking mechanism is combined with the dislocation locking principle of the J-shaped rod and the horizontal bar. While ensuring that the nursing staff can quickly complete the fastening / unfastening operation, it makes it difficult for the disabled and demented to trigger the unfastening through a single action or unconscious behavior, effectively preventing the risk of involuntary undressing.

[0021] 2. The spring-driven self-reset structure not only ensures the stability of the buckled state, but also reduces the pressure of mechanical parts on the body through buffer design.

[0022] 3. The J-shaped rod is rotatably connected to the bottom of the moving plate through a sleeve, and a torsion spring is arranged in the sleeve. The side end of the J-shaped rod is connected to the torsion spring. Under the action of the torsion spring, the J-shaped rod can be ensured to be perpendicular to the cross bar in a natural state. When the hook of the J-shaped rod contacts the cross bar, the resistance causes the J-shaped rod to rotate, and the torsion spring accumulates force. When the hook of the J-shaped rod is separated from the cross bar, the torsion spring drives the J-shaped rod to rotate and reset without resistance. Through this structural design, the stability and firmness of the hook lock in this design are enhanced. At the same time, the force accumulation and release process of the torsion spring is smooth and powerful, which reduces mechanical wear and extends the service life of the mechanism buckle.

[0023] 4. By pressing the movable disk, the two J-shaped rods are separated from the cross bar. Then the caregiver only needs to turn the pressing thumb to make the movable disk rotate on the disk, so that the two J-shaped rods can be staggered with the corresponding cross bars. Then, by releasing the fingers, one-hand unlocking can be completed. A track groove is provided, and the track groove and the slider limit the rotation range of the movable disk on the disk to avoid the mechanism being stuck due to excessive rotation, thereby ensuring the one-time success rate of the operation. When the slider slides over the track groove, a stepped damping feeling is generated, and the operator can perceive the progress of the unbuttoning without visual observation. The traditional two-handed operation is simplified to a single-handed thumb pressing and rotating compound action, and the caregiver can complete the unbuttoning faster.

[0024] 5. By setting an arc-shaped tension spring, when the slider slides in the track groove, the arc-shaped tension spring can be stretched and stored. When the movable plate is released, the arc-shaped tension spring will contract, and under the cooperation of the attraction between magnet one and magnet two, the movable plate can slowly rotate and reset. Therefore, the rotation and reset speed of the two J-shaped rods is lower than the speed at which the spring drives the two J-shaped rods to move upward, so that the sides of the two J-shaped rod hooks can be arranged between the two cross bars, ensuring that the mechanism buckle can be unfastened in one go. Through this structural design, it is convenient for the staff to quickly complete the unfastening and buckling with one hand, and ensure the consistency of the position of the J-shaped rod during use.

DETAILED DESCRIPTION

[0032] The following is combined with Figures 1 to 5 The present invention is described in further detail.

[0033] It should be noted that the drawings are schematic and not to scale. For the sake of clarity and convenience, the relative sizes and proportions of the parts shown in the drawings are exaggerated or reduced in size, and any size is only illustrative and not restrictive. In addition, the same reference symbol is used for the same structure, element or accessory appearing in more than two figures to reflect similar features.

[0034] Embodiment 1

[0035] The embodiment of the present invention discloses a mechanism buckle. Figures 1 to 5 A mechanism buckle comprises a sub-buckle 1, a mother buckle 2 and a locking mechanism 3, wherein the locking mechanism 3 is arranged in the sub-buckle 1; the mother buckle 2 comprises a round sleeve 200, wherein a pair of cross bars 201 are arranged inside the round sleeve 200; the sub-buckle 1 comprises a disc 100, wherein an inner sleeve 101 is arranged at the bottom of the disc 100, an outer sleeve 102 is slidably arranged at the bottom of the inner sleeve 101, and a spring 103 is arranged between the outer sleeve 102 and the disc 100; the locking mechanism 3 comprises two J-shaped rods 300 arranged at the bottom of the disc 100, and the bending areas of the two J-shaped rods 300 are arranged at the bottom of the outer sleeve 102, and the two J-shaped rods 300 correspond to the positions of the two cross bars 201.

[0036] Specifically, the mechanism button of the present invention is sewn on the functional nursing clothing. When fastening, the sub-button 1 is aligned with the female button 2, and the two J-shaped rods 300 are aligned with the cross bar 201, and then the sub-button 1 is pressed down. At this time, the bottom of the outer set 102 will contact the top of the disc 100, and the hooks on the two J-shaped rods 300 will contact the cross bar 201. Under the resistance of the cross bar 201, the two J-shaped rods 300 rotate to approach each other, and the disc 100 continues to move downward. The bottom of the inner set 101 will contact the inner wall of the outer set 102, and the spring 103 will shrink. At this time, the hooks of the two J-shaped rods 300 are completely staggered with the cross bar 201, and the two J-shaped rods 300 are no longer blocked and rotated to reset. Finally, the disc 100 is released. At this time, the spring 103 will stretch, thereby driving the two J-shaped rods 300 to hook the cross bar 201, thereby completing the fastening between the sub-button 1 and the female button 2;

[0037] When unbuttoning, it is only necessary to press down the sub-button 1 and rotate the sub-button 1 so that the two J-shaped rods 300 are offset from the cross bar 201, and then release the sub-button 1 to complete the unbuttoning of the sub-button 1 and the mother button 2;

[0038] Through this structural design, the safety protection performance of functional nursing clothing is improved. The double-action unlocking mechanism is combined with the offset locking principle of the J-shaped rod 300 and the cross bar 201. While ensuring that nursing staff can quickly complete the fastening / unfastening operation, it makes it difficult for disabled and demented people to trigger unfastening through a single action or unconscious behavior, effectively preventing the risk of involuntary undressing. The self-resetting structure driven by the spring 103 not only ensures the stability of the fastened state, but also reduces the pressure of mechanical components on the body through the buffer design.

[0039] like Figure 2 and Figure 4 As shown, the locking mechanism 3 includes a movable disk 301 disposed on the top of the disk 100 , and two J-shaped rods 300 are rotatably disposed at the bottom of the movable disk 301 through torsion springs 302 .

[0040] Specifically, the J-shaped rod 300 is rotatably connected to the bottom of the moving disk 301 through a sleeve, and the torsion spring 302 is arranged in the sleeve, and the side end of the J-shaped rod 300 is connected to the torsion spring 302. Under the action of the torsion spring 302, the J-shaped rod 300 can be ensured to be perpendicular to the cross bar 201 in a natural state. When the hook of the J-shaped rod 300 contacts the cross bar 201, the resistance causes the J-shaped rod 300 to rotate, and the torsion spring 302 accumulates force. When the hook of the J-shaped rod 300 is separated from the cross bar 201, the torsion spring 302 drives the J-shaped rod 300 to rotate and reset without obstruction. Through this structural design, the stability and firmness of the hook lock in this design are enhanced. At the same time, the force accumulation and release process of the torsion spring 302 is smooth and powerful, which reduces mechanical wear and extends the service life of the mechanism buckle.

[0041] Embodiment 2

[0042] This embodiment is further optimized on the basis of the above embodiment 1, and the same parts as the above technical solution will not be repeated here. Figure 1 and Figure 2 As shown, in order to better implement the present invention, the following configuration is particularly adopted: in this embodiment, an anti-slip pattern 303 is provided on the top of the moving disk 301 .

[0043] Specifically, by providing the anti-slip pattern 303 , it is convenient for nursing staff to rotate the movable disk 301 .

[0044] Embodiment 3

[0045] This embodiment is further optimized on the basis of the above embodiment 1, and the same parts as the above technical solution will not be repeated here. Figure 4 and Figure 5 As shown, in order to better realize the present invention and improve the unfastening speed, the following setting is particularly adopted: in this embodiment, the locking mechanism 3 also includes two track grooves 304 opened on the inner wall of the disc 100, and sliders 305 are slidably arranged inside the two track grooves 304, and the sliders 305 are fixedly connected to the bottom of the moving disc 301 through vertical pads.

[0046] Specifically, when unlocking, the caregiver presses the movable disk 301 to separate the two J-shaped rods 300 from the cross bar 201 (the inner set 101 and the outer set 102 are in a compressed state), and then the caregiver only needs to turn the pressing thumb to rotate the movable disk 301 on the disk 100, so that the two J-shaped rods 300 can be staggered with the corresponding cross bar 201, and then release the fingers to complete the one-hand unlocking. A track groove 304 is provided, and the track groove 304 and the slider 305 limit the rotation range of the movable disk 301 on the disk 100 to avoid the mechanism being stuck due to excessive rotation, thereby ensuring the one-time success rate of the operation. When the slider 305 slides over the track groove 304, a stepped damping feeling is generated, and the operator can sense the unlocking progress without visual observation.

[0047] The traditional two-hand operation is simplified into a single-hand thumb pressing and rotating compound action, so that nursing staff can complete the unbuttoning process faster.

[0048] like Figure 5 As shown, the inner wall of the track groove 304 is provided with an arc groove 306, and an arc tension spring 307 is arranged inside the arc groove 306. One end of the arc tension spring 307 is fixedly connected to the arc groove 306, and the other end of the arc tension spring 307 is fixedly connected to the slider 305. The arc tension spring 307 is arranged to ensure the reset of the J-shaped rod 300 after being unfastened.

[0049] like Figure 5As shown, a magnet 1 308 is disposed on the side of the slider 305, and a magnet 2 309 is disposed on the side of the track groove 304 away from the slider 305. The magnetic poles of magnet 1 308 and magnet 2 309 are different. The provision of magnet 1 308 and magnet 2 309 can ensure that the two J-shaped rods 300 are reset to between the two cross bars 201.

[0050] Specifically, by setting an arc-shaped tension spring 307, when the slider 305 slides in the track groove 304, the arc-shaped tension spring 307 can be stretched and stored. When the movable disk 301 is released, the arc-shaped tension spring 307 will contract, and under the cooperation of the attraction of magnet 1 308 and magnet 2 309, the movable disk 301 can slowly rotate and reset. As a result, the rotation and reset speed of the two J-shaped rods 300 is lower than the speed at which the spring 103 drives the two J-shaped rods 300 to move upward, so that the side surfaces of the hooks of the two J-shaped rods 300 can be arranged between the two cross bars 201, ensuring that the mechanism buckle can be unfastened in one go. Through this structural design, it is convenient for the staff to quickly complete the unfastening and buckling of the mechanism buckle with one hand, and ensure the consistency of the position of the J-shaped rod 300 during use.

[0051] Specifically, the attraction between the first magnet 308 and the second magnet 309 after contact is smaller than the elastic force of the arc-shaped tension spring 307 .

[0052] Specifically, the outer edges of the sub-button 1 and the female button 2 are both rounded.

[0053] like Figure 1 and Figure 2 As shown, both the sub-button 1 and the main button 2 are provided with sewing holes.

[0054] It is worth noting that the mechanism buckle of the present invention has a wide range of applicability, not only limited to the field of clothing, but also can play an important role in multiple scenarios where misoperation needs to be prevented or safety needs to be improved. For example, in the field of anti-mistouch luggage, it can effectively prevent the accidental opening of luggage due to accidental collisions or unconscious movements, and ensure the safety of property; in terms of food and medicine packaging boxes, it can prevent children or cognitively impaired people from opening the packaging by mistake, and avoid accidentally ingesting medicines or spoiled food, ensuring health and safety. In addition, it can also be applied to electronic device protective shells to prevent accidental opening of the device shell and damage caused by accidental falls; in the fixing of storage boxes or decorations inside cars, it can prevent bumps during vehicle driving and cause items to fall or shift; in the closing and opening control of household items such as cabinet doors and drawers, it can also prevent misoperation or accidental opening by pets, and protect the safety and privacy of family members. In short, the design and function of the mechanism buckle of the present invention can provide safer and more reliable protection for people's lives and work in many fields.

[0055] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art and will not be described in detail here.

[0056] The implementation principle of a mechanism buckle of an embodiment of the present invention is as follows: after the mechanism buckle of the present invention is sewn on the functional nursing clothing, when performing the fastening operation, first align the sub-button 1 with the mother buckle 2, and ensure that the two J-shaped rods 300 are aligned with the cross bar 201, and then press the sub-button 1. During this process, the bottom of the outer set 102 will contact the top of the disc 100, and the hooks on the two J-shaped rods 300 will also contact the cross bar 201. Due to the resistance of the cross bar 201, the two J-shaped rods 300 will rotate and approach each other. At this time, the disc 100 continues to move downward, the bottom of the inner set 101 will contact the inner wall of the outer set 102, and the spring 103 will shrink. When the hooks of the two J-shaped rods 300 are completely offset from the cross bar 201, the two J-shaped rods 300 are no longer blocked and will rotate and reset under the action of the torsion spring 302. Finally, the disc 100 is released, and the spring 103 will stretch, thereby driving the two J-shaped rods 300 to hook the crossbar 201, thereby completing the buckling between the sub-button 1 and the female button 2;

[0057] When unbuttoning, the nursing staff first presses down the sub-button 1 and rotates the sub-button 1 to make the two J-shaped rods 300 staggered with the cross bar 201, and then releases the sub-button 1 to complete the unbuttoning of the sub-button 1 and the mother buckle 2;

[0058] Specifically, during the unfastening process, the nursing staff presses the movable disk 301, at which time the inner set 101 and the outer set 102 are in a compressed state, so that the two J-shaped rods 300 are separated from the cross bar 201, and then the nursing staff only needs to turn the pressing thumb to rotate the movable disk 301 on the disk 100, so that the two J-shaped rods 300 can be staggered with the corresponding cross bar 201, and then release the finger to complete the one-hand unlocking. The setting of the track groove 304 and the slider 305 limits the rotation range of the movable disk 301 on the disk 100, avoiding the mechanism from being stuck due to excessive rotation, ensuring the one-time success rate of the operation, and when the slider 305 slides over the track groove 304, a stepped damping feeling will be generated, and the operator can perceive the unfastening progress without visual observation;

[0059] In addition, by providing the arc-shaped tension spring 307, when the slider 305 slides in the track groove 304, the arc-shaped tension spring 307 can be stretched and stored. When the movable plate 301 is released, the arc-shaped tension spring 307 will contract, and under the cooperation of the attraction of the first magnet 308 and the second magnet 309, the movable plate 301 can slowly rotate and reset, so that the speed of the two J-shaped rods 300 rotating and resetting is lower than the speed of the spring 103 driving the two J-shaped rods 300 to move upward, so that the side surfaces of the hooks of the two J-shaped rods 300 can be arranged between the two cross bars 201, ensuring that the buckle of the mechanism is released in one time;

[0060] This structural design allows staff to quickly complete one-handed unbuttoning and one-handed buckling, and ensures the consistency of the position of the J-shaped rod 300 during use. It ensures that caregivers can quickly complete the buckling / unbuttoning operations while making it difficult for disabled and demented people to trigger unbuttoning through a single action or unconscious behavior, effectively preventing the risk of involuntary undressing and improving the safety protection effectiveness of functional nursing clothing.
