Description
Technical Field
[0001] The utility model belongs to the technical field of clamps, in particular to a clothespin. Background Art
[0002] Traditional clothespins are usually designed in a single size and shape to fit a specific clothesline or rod. Although this design is simple, it has some limitations in actual use: (1) A single-sized clothespin may not be able to adapt to clotheslines or rods of different thicknesses, limiting its applicability in diverse environments. (2) If the size of the clothespin does not match the clothesline or rod, the mismatched size of the clip may be damaged during use due to over-clamping or insufficient clamping, making clothes easily slip off or blown away by the wind, affecting their durability, or causing clothes to pile up and affect drying efficiency. (3) The force arm of the torsion spring is in contact with the handle, and the torsional torque of the torsion spring is transmitted to the clamp through the handle. Because the force arm is long, this design makes the clamp easy to open and close, but the clamping force provided is relatively small and cannot adapt to extreme weather such as strong winds. The opening angle between the two handles meets the requirements of a larger torsion angle, which takes up a lot of space. Utility Model Content

DETAILED DESCRIPTION
[0032] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
[0033] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.
[0034] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
[0035] Example 1
[0036] like Figure 1-5 A clothespin, suitable for securing clothing to a clothesline or pole, comprises a torsion spring 200 and two symmetrically arranged unit clips 101. Unit clips 101 comprise a clamping portion 104, a rotating portion 105, and an operating portion 106, arranged in sequence. The two operating portions 106 are provided with groove structures with raised ends in opposite directions. The groove structures are covered with a second elastic layer 115, which has a plurality of anti-slip ribs 119 adapted to contact the hand. The groove structure conforms to ergonomic principles and can naturally adapt to the contours of the human hand, especially the fingertips. This increases the contact area between the hand and the clothespin, ensuring uniform force application and a more comfortable and secure grip. Even with fingers stained with laundry detergent, the clothespin can be opened without slipping. The clamping portion 104 includes a clamp 107, an escape zone 108, and a limiter 113, which are sequentially arranged. The escape zone 108 includes arcuate surfaces of varying diameters. The torsion spring 200 is adapted to drive the two clamps 107 into close contact, while the limiter 113 and the clamp 107 maintain contact. The arcuate surfaces of the two escape zones 108 are adapted to enclose a loop area suitable for accommodating clotheslines or rods of different sizes. The clamps 107 and the limiter 113 are adapted to prevent the clothesline or rod from escaping the loop area. The two clamps 107 are provided with a first elastic layer 114 facing each other. The elastic layer has a flat surface suitable for contacting clothing, ensuring that the clamps 107 do not leave marks on clothing or damage it. The unit clip 101 includes a back panel 102 and two side panels 103. Parts of the side panels 103 are adapted to form the two arcuate surfaces and the two limiters 113.
[0037] In this embodiment, the avoidance zone 108 includes three sets of parallel first arc surfaces 109 and three sets of parallel second arc surfaces 110. The two first arc surfaces 109 are adapted to enclose a first loop region 111, and the two second arc surfaces 110 are adapted to enclose a second loop region 112. The first loop region 111 and the second loop region 112 are discontinuous arc structures. The first loop region 111 has a first radius R1 of 10 mm, and the second loop region 112 has a second radius R2 of 2 mm. The first loop region 111 and the second loop region 112 are compatible with clotheslines with diameters ranging from 2 mm to 10 mm. The first loop region 111 is positioned adjacent to the clamp 107. A transition plane 120 is provided between the first arcuate surface 109 and the second arcuate surface 110. When the two clamps 107 are directly in contact, a 1mm gap is left between the two transition planes 120 to prevent the clothesline from slipping from the second loop area 112 to the first loop area 111. In some other embodiments, when the two clamps 107 are directly in contact, the two transition planes 120 also directly contact, and the first loop area 111 and the second loop area 112 are disconnected. Testing has shown that when the length of the clothesline is no less than the length of the first loop area 111 or the second loop area 112, the clothespin can remain stable and non-slip in wind conditions of force 5. Maintaining a certain distance between clothes facilitates moisture evaporation, thereby improving the efficiency and uniformity of drying clothes.
[0038] In this embodiment, the torsion spring 200 includes a spring coil 201, a first arm 202, and a second arm 203. The first arm 202 and the second arm 203 extend outward from both ends of the spring coil 201 in the same direction and intersect with each other. A first leg 204 is formed at the end of the first arm 202, and a second leg is formed at the end of the second arm 203. A retaining groove 116 for the first leg 204 or the second leg 205 to engage is provided in the central area of the back plate 102 corresponding to the clamping portion 104. Both the first leg 204 and the second leg are arranged parallel to the axial direction of the spring coil 201. Furthermore, the horizontal projections of the first leg 204 and the second leg 205 at least partially overlap, which facilitates the continuous and stable transmission of torsional torque to the clamping portion 104. The maximum weight of clothing that can be clamped is 1.2 kg.
[0039] In this embodiment, the rotating portion 105 includes a plurality of first support portions 117 arranged parallel to the axial direction of the spring coil 201 and a plurality of second support portions 118 arranged perpendicular to the axial direction of the spring coil 201. Portions of the side plate 103 are adapted to form the second support portions 118. The second support portions 118 include arcuate surfaces adapted to engage with the spring coil 201. The first and second support legs 204 and 203 act to radially constrain the spring coil 201, and the first and second lever arms 202 and 203 are adapted to clamp the spring coil 201 on either side of the clip.
[0040] In this embodiment, the rotating portion 105 includes a starting end and a terminating end. One first support portion 117 and the end of the mating arc surface constitute the starting end, while the other first support portion 117 and the other end of the mating arc surface constitute the terminating end. When the two starting ends collide, the two clamps 107 maintain their initial, tightly fitted state. When the two terminating ends collide, the two clamps 107 open to their maximum extent.
[0041] Example 2
[0042] A clothespin, compared with Example 1, differs in that it includes a torsion spring and a first clip and a second clip that are not completely the same, the first clip includes a first clamping part and a first operating part, the first clamping part includes a first clamping head and a first avoidance area, the first avoidance area includes a first arc surface A and a second arc surface B with different radial lengths, the second clip includes a second clamping part and a second operating part, the second clamping part includes a second clamping head and a second avoidance area, the second avoidance area includes several second arc surfaces A and second arc surfaces B with different radial lengths, the torsion spring is suitable for driving the first clamping head and the second clamping head to fit tightly together, and at the same time, the first arc surface A and the second arc surface A have the same radial dimensions and are suitable for enclosing to form a loop area A, the first arc surface A can have different circumferential dimensions from the second arc surface A, the first arc surface B and the second arc surface B have the same radial dimensions and are suitable for enclosing to form a loop area B, the first arc surface B and the second arc surface B have different circumferential dimensions, and the loop area A and the loop area B are complete arc structures or discontinuous arc structures.
