Description

Technical Field

[0001] The utility model relates to a button, in particular to a telescopic button. Background Art

[0002] Buttons are devices used to fasten clothes and play a role in fixing clothes. They are generally set at positions such as the front placket, cuffs, and collars. In existing clothes, buttons are usually used fixedly. During the use of the cuffs of shirts and other clothes, the cuffs of shirts have no elasticity, making it difficult to roll up the sleeves, and the rolled-up sleeves are easy to fall off. To solve the problem of sleeve adjustment for people when dressing. Therefore, a button that can be used telescopically is needed to meet the adjustment needs of people's cuffs.

[0003] The existing patent CN211431183U discloses a spring extension button, which includes a button and a spring. The button is connected to the spring. The spring is stuck inside the button. The spring is buckled on the button of the original button on the clothes. The button connected by the spring is connected to the original button hole on the clothes to realize the extension of the waist, cuffs, and collar of the clothes, and the operation is convenient and fast. However, this patent uses an external spring to achieve the extension function. Since the spring is external, the spring has a certain length in the natural state, resulting in an obvious extension part of the button. Due to the existence of this extension part, on the one hand, this extension part can only be stretched and cannot be contracted, resulting in that within the length range of this extension part, telescopic adjustment cannot be performed, and the practicability is poor; on the other hand, the external spring is connected to the cylinder on the button, which is not beautiful enough. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a telescopic button to solve the problems of poor practicability and lack of beauty of the existing telescopic buttons.

[0005] The utility model is realized as follows: A telescopic button includes a button housing and a telescopic rope. A through hole is opened on the end face of the button housing. The body of the telescopic rope is located inside the button housing, and the end of the telescopic rope extends out of the button housing through the through hole; A track structure and a blocking structure are arranged in the inner cavity of the button housing. The body of the telescopic rope passes through the blocking structure and the track structure in sequence after passing through the through hole. A spring is sleeved on the body of the telescopic rope. The inner end of the spring is connected to the telescopic rope. The part of the elastic rope body sleeved with the spring passes through the track structure, and the outer end of the spring is restricted from moving by the blocking structure.

[0006] Further, a convex block is arranged inside the button housing. A track structure is formed between the outer side edge of the convex block and the side wall of the housing. One end corner of the outer side edge of the convex block protrudes towards the side wall of the housing to form a blocking structure, making the end of the track structure narrower.

[0007] Further, the threading hole is located in the middle of one end face of the button housing. There are two track structures and two blocking structures respectively, which are centrosymmetric about the center of the threading hole. There are two sections of the telescopic rope, and the two sections of the telescopic rope respectively pass through different blocking structures and track structures in sequence.

[0008] Further, the extending ends of the two sections of the telescopic rope are connected to each other and are connected with a limiting structure whose contour is larger than the threading hole.

[0009] Further, the blocking mechanism is a baffle plate, and through holes are formed in the baffle edge. The diameter of the through holes is larger than the diameter of the telescopic rope and smaller than the diameter of the spring end.

[0010] Further, the inner wall of the threading hole is a fillet structure.

[0011] Further, the button housing includes a first housing and a second housing that are snap-fitted to each other.

[0012] The second implementation structure of the present invention is a retractable button, which includes a button housing and a telescopic rope. A threading hole is formed in the end face of the button housing. The body of the telescopic rope is located inside the button housing, and the end of the telescopic rope extends out of the button housing through the threading hole; an extension part extending towards the inside of the button housing is provided at the threading hole, and through holes are formed in the extension part. The body of the telescopic rope enters the inside of the button housing through the through holes after passing through the threading hole. A spring is sleeved on the body of the telescopic rope. The inner end of the spring is connected to the telescopic rope, and the outer end of the spring is blocked and limited by the extension part.

[0013] The third implementation structure of the present invention is a retractable button, which includes a button housing and a telescopic rope. A threading hole is formed in the end face of the button housing. The body of the telescopic rope is located inside the button housing, and the end of the telescopic rope extends out of the button housing through the threading hole; an extension part extending towards the inside of the button housing is provided at the threading hole, and through holes are formed in the extension part. The telescopic rope is an elastic rope. The body of the telescopic rope enters the inside of the button housing through the through holes after passing through the threading hole. A track structure is provided inside the button housing, and the body of the telescopic rope is located inside the track structure. The end of the telescopic rope is fixed inside the button housing.

[0014] Further, an arc-shaped guide plate is provided inside the button housing. A track structure is formed between the arc-shaped guide plate and the side wall of the button housing. A fixing structure for fixing the end of the telescopic rope is provided at the end of the track structure.

[0015] In the present utility model, the body of the retractable rope is hidden inside the button housing. The outer end of the retractable rope extends out of the button housing through the through-hole. The outer end of the retractable rope is buckled on the original button or directly fixed at the position where the original button is located, and the button housing replaces the original button and is buckled in the button hole. When the cuffs, collars and other parts using the present utility model need to be expanded, the retractable rope is pulled out / stretched to provide a certain expansion dimension for the clothing. When the expansion force disappears, the retractable rope retracts / contracts, and only a very short end of the retractable rope is exposed outside the button housing to provide the necessary part for buckling with the original button or connecting with the clothing.

[0016] Since there is a relatively large cavity inside the button housing to accommodate the long retractable rope, the present utility model can have a relatively large expansion adjustment range, and the length of the retractable rope can be determined according to needs. At the same time, since only a very short necessary part of the retractable rope is located outside the button housing, the whole is more beautiful and there will be no extended part that cannot be expanded and adjusted.

[0024] The following further elaborates on the present utility model in conjunction with the embodiments. The following embodiments are only for illustration and do not limit the protection scope of the present utility model in any way.

[0025] Embodiment 1

[0026] As Figure 1 , Figure 2As shown in the figure, the retractable button of this embodiment mainly includes a button housing 1, a retractable cord 2, a spring 6, a limiting structure 9, etc. A through-hole 5 is provided on the end face of the button housing 1. The main body part of the retractable cord 2 is located inside the button housing 1, and the end part of the retractable cord 2 with a very small length extends out of the button housing 1 through the through-hole 5.

[0027] A track structure 3 and a blocking structure 4 are arranged in the inner cavity of the button housing 1. The main body of the retractable cord 2 passes through the through-hole 5 and then passes through the blocking structure 4 and the track structure 3 in sequence. A spring 6 is sleeved on the main body of the retractable cord 2. The inner end of the spring 6 is connected to the retractable cord 2. The main body part of the retractable cord 2 sleeved with the spring 6 passes through the track structure 3, and the outer end of the spring 6 is restricted from moving by the blocking structure 4.

[0028] A clamping block is arranged at the inner end of the retractable cord 2. The diameter of the clamping block is larger than the diameter of the end of the spring 6, or the end of the retractable cord 2 is directly fixedly connected to the end of the spring 6 to limit the inner end of the spring 6, while the outer end of the spring 6 is restricted from displacement by the blocking structure 4. In this way, when the retractable cord 2 moves outwards, the spring 6 will be compressed.

[0029] Among them, the track structure 3 is used to accommodate all or part of the elastic cord main body part sleeved with the spring 6, accommodate and guide the main body part of the retractable cord 2 sleeved with the spring 6. Through the guiding function, it prevents the relatively soft spring 6 from deforming due to the pulling force, resulting in the spring 6 wire and the retractable cord 2 being stuck in the track, and preventing smooth contraction. When the retractable cord 2 is pulled, the main body part of the retractable cord 2 moves along the track structure 3 to compress the spring 6, so that the exposed end of the retractable cord 2 elongates. When the pulling force acting on the retractable cord 2 disappears, the restoring force of the spring 6 drives the exposed part of the retractable cord 2 to retract.

[0030] Preferably, a part of the main body of the retractable cord 2 sleeved with the spring 6 is located inside the track structure 3, and the other part freely extends into the button housing 1. The spring 6 automatically contracts and releases in this area without being blocked, and the contraction is smooth.

[0031] Among them, the retractable cord 2 can be a rigid cord without elasticity or an elastic cord with elasticity. When the retractable cord 2 is a rigid cord, the expansion and contraction of the retractable cord 2 are completely realized by the compression or restoration of the spring 6, and the expansion range can be determined by the expansion range of the spring 6; when the retractable cord 2 is an elastic cord, it will also elongate and retract to a certain extent. Under the condition that the length of the retractable cord 2 and the specifications of the spring 6 are the same, compared with the rigid cord, it has a larger expansion range.

[0032] Among them, the track structure 3 and the blocking structure 4 can have various structural forms. The track structure 3 is basically located on the outer ring of the inner cavity of the button housing 1, and the blocking structure 4 is located at the end of the track structure 3.

[0033] In this embodiment, as Figure 1 shown, a bump 7 is provided inside the button housing 1, and a track structure 3 is formed between the outer side of the bump 7 and the side wall of the housing. One end corner of the outer side of the bump 7 protrudes towards the side wall of the housing to form a blocking structure 4, narrowing the end of the track structure 3. The telescopic cord 2 sleeved with a spring 6 is located inside the track structure 3. Since the width of the track structure 3 narrows at the end, the spring 6 cannot pass through, thereby restricting the displacement of the outer end of the spring 6.

[0034] One end of the bump 7 is a flat surface. The telescopic cord 2 passes through the flat surface part after passing through the through hole 5, and then enters the track structure 3 after passing through the protruding blocking structure 4; the other end of the bump 7 is arc-shaped.

[0035] The track structure 3 and the blocking mechanism can also be realized by a guide plate protruding from the end face of the inner cavity of the button housing 1. In addition to being formed by the side of the bump 7 and the inner wall of the housing, the track structure 3 can also be formed by the side of the bump 7 and the guide plate, or by two guide plates. Correspondingly, the blocking structure 4 is realized by the narrowing of the track structure 3 formed in the above implementation manner.

[0036] As Figure 2 shown, another structure of this embodiment is given, where the blocking mechanism is a baffle 8, and a through hole is opened on the baffle edge. The diameter of the through hole is larger than the diameter of the telescopic cord 2 and smaller than the diameter of the end of the spring 6, and the movement of the outer end of the spring 6 is restricted by the baffle 8. In addition to being formed by the side of the bump 7 and the inner wall of the housing, the track structure 3 can also be formed by the side of the bump 7 and the guide plate, or by two guide plates.

[0037] In this embodiment, the telescopic cord 2 can be one section, that is, there is only one track structure 3 and one blocking structure 4 inside the button housing 1. After one section of the telescopic cord 2 enters through the through hole 5, it passes through the blocking structure 4 and the track structure 3 in sequence, and a spring 6 is sleeved on the telescopic cord 2.

[0038] Preferably, the telescopic cord 2 is two sections. The through hole 5 is located in the middle of one end face of the button housing 1. There are two track structures 3 and two blocking structures 4 respectively, and they are centrosymmetric around the center of the through hole 5. There are two sections of the telescopic cord 2 in total. The two sections of the telescopic cord 2 enter through the through hole 5 at the same time and pass through different blocking structures 4 and track structures 3 respectively.

[0039] The exposed parts of the two sections of the telescopic cord 2 are connected to each other. Among them, the two telescopic cords 2 can be connected at the exposed end parts, or one telescopic cord 2 can be folded in half to form two sections of the telescopic cord 2, and the folding point is the exposed part.

[0040] Since the angle of the telescopic cord 2 changes the most when passing through the threading hole 5, the inner wall of the threading hole 5 is a rounded corner structure to reduce the wear of the telescopic cord 2.

[0041] In addition, in this embodiment, the rounded corner treatment is also required at each corner to ensure smooth telescoping.

[0042] The button housing 1 includes a first housing 1-1 and a second housing 1-2 that are snap-fitted together. The openable and closable button housing 1 facilitates the assembly of internal components.

[0043] As Figure 3 shown, for the form of two telescopic cords 2, a limiting structure 9 with a contour larger than the threading hole 5 is connected to the exposed end of the telescopic cord 2. The limiting structure 9 can be a spherical, ellipsoidal, cylindrical or other structure, which is used to prevent the exposed end of the telescopic cord 2 from entering the interior of the button housing 1 through the threading hole 5. The exposed part is in the shape of a cable sleeve after being stretched and can be buckled on the original button on the clothing.

[0044] For the form of a single telescopic cord 2, the outer end of the telescopic cord 2 cannot be buckled on the original button on the clothing. The outer end of the telescopic cord 2 can be fixed at the position of the original button by sewing or other means, replacing the original button with the present utility model, or connecting the outer end of the telescopic cord 2 to the original button in other forms.

[0045] Embodiment 2

[0046] As Figure 4 shown, the retractable button of this embodiment mainly includes a button housing 1, a telescopic cord 2 and a spring 6. A threading hole 5 is provided on the end face of the button housing 1. The body of the telescopic cord 2 is located inside the button housing 1, and the end of the telescopic cord 2 extends out of the button housing 1 through the threading hole 5. An extension part 10 extending towards the inside of the button housing 1 is provided at the threading hole 5, and a through hole is provided on the extension part 10. The body of the telescopic cord 2 passes through the threading hole 5 and enters the inside of the button housing 1 through the through hole. A spring 6 is sleeved on the body of the telescopic cord 2. The inner end of the spring 6 is connected to the telescopic cord 2, and the outer end of the spring 6 is blocked and limited by the extension part 10.

[0047] Among them, the extension part 10 is annular, the extension part 10 is coaxially arranged with the threading hole 5, the through hole is provided on the side wall of the extension part 10, and the diameter of the through hole is larger than the diameter of the telescopic cord 2 and smaller than the diameter of the end of the spring 6.

[0048] In this embodiment, the track structure 3 is not provided, and the single telescopic cord 2 form is adopted. One telescopic cord 2 passes through the threading hole 5 and enters the button housing 1. After passing through the through hole of the extension part 10, it is naturally coiled in the cavity of the button housing 1. A spring 6 is sleeved on the telescopic cord 2. The connection form between the inner end of the spring 6 and the telescopic cord 2 is the same as that in Embodiment 1, and the outer end of the spring 6 is restricted from moving by the extension part 10 and the through hole.

[0049] Among them, the telescopic rope 2 can be a rigid rope without elasticity or an elastic rope with elasticity. When the telescopic rope 2 is a rigid rope, the telescoping of the telescopic rope 2 is completely achieved by the compression or restoration of the spring 6, and the telescopic range can be determined by the telescopic range of the spring 6; when the telescopic rope 2 is an elastic rope, it will also elongate and retract to a certain extent itself. In the case where the length of the telescopic rope 2 and the specifications of the spring 6 are the same, compared with the rigid rope, it has a larger telescopic range.

[0050] The button housing 1 includes a first housing 1-1 and a second housing 1-2 that are snap-fitted to each other. The openable and closable button housing 1 facilitates the assembly of internal components.

[0051] For this embodiment, since the cavity of the button housing 1 is relatively large, more telescopic ropes 2 can be accommodated. The lengths of the telescopic rope 2 and the spring 6 can be much greater than those in the first embodiment, so a larger telescopic range can be provided.

[0052] However, for this embodiment, since the single telescopic rope 2 form is adopted, the outer end of the telescopic rope 2 cannot be buckled to the original button. It can be fixed at the position of the original button by sewing or other means, or the outer end of the telescopic rope 2 can be connected to the original button in other forms.

[0053] Embodiment Three

[0054] As Figure 5 、 Figure 6 shown, the retractable button of this embodiment mainly includes a button housing 1 and a telescopic rope 2. A through hole 5 is provided on the end face of the button housing 1. The body of the telescopic rope 2 is located inside the button housing 1, and the end of the telescopic rope 2 extends out of the button housing 1 through the through hole 5. An extension part 10 extending towards the inside of the button housing 1 is provided at the through hole 5, and a through hole is provided on the extension part 10. The telescopic rope 2 is an elastic rope. The body of the telescopic rope 2 passes through the through hole 5 and then enters the inside of the button housing 1 through the through hole. A track structure 3 is provided inside the button housing 1, and the body of the telescopic rope 2 is located inside the track structure 3. The end of the telescopic rope 2 is fixed inside the button housing 1.

[0055] Among them, the extension part 10 is annular, the extension part 10 is coaxially arranged with the through hole 5, the through hole is provided on the side wall of the extension part 10, and the diameter of the through hole is larger than the diameter of the telescopic rope 2.

[0056] In this embodiment, the single contraction rope form is adopted and the spring 6 is not used. The telescopic rope 2 is an elastic telescopic rope 2, which provides the elastic force for telescoping by itself. After the telescopic rope 2 enters the button housing 1 through the through hole 5, it passes through the track structure 3, and the track structure 3 guides the telescopic rope 2. The inner end of the telescopic rope 2 is fixed. When a pulling force is applied to the outer end of the telescopic rope 2, the telescopic rope 2 elongates, and when the pulling force disappears, the telescopic rope 2 automatically retracts.

[0057] Among them, an arc-shaped guide plate 11 is arranged inside the button housing 1. A track structure 3 is formed between the arc-shaped guide plate 11 and the side wall of the button housing 1. Multiple turns of arc-shaped guide plates 11 can also be arranged, and a track structure 3 is also formed between two adjacent turns of arc-shaped guide plates 11. The length and number of turns of the arc-shaped guide plate 11 can be set according to needs. A fixing structure 12 for fixing the end of the telescopic rope 2 is arranged at the end of the track structure 3. The fixing structure 12 is specifically an end plate structure with a through hole. The inner end of the telescopic rope 2 passes through the through hole of the end plate. A clamping block is arranged at the inner end of the telescopic rope 2, and the diameter of the clamping block is larger than the diameter of the through hole, so as to fix the end of the telescopic rope 2. The end of the telescopic rope 2 can also be fixed in other forms.

[0058] The button housing 1 includes a first housing 1-1 and a second housing 1-2 that are buckled with each other. The openable and closable button housing 1 facilitates the assembly of internal components.

[0059] In this embodiment, since the single-segment telescopic rope 2 is adopted, the outer end of the telescopic rope 2 cannot be buckled on the original button on the clothing. The outer end of the telescopic rope 2 can be fixed at the position of the original button by sewing or other means, replacing the original button with the utility model, or connecting the outer end of the telescopic rope 2 to the original button in other forms.

[0060] For this embodiment, since the spring 6 is not provided, its thickness can be made thinner, so that it is closer to an ordinary button in appearance and more beautiful.
