Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] Please also read Figures 1 to 6 The clothes clip provided by the present invention is now described. The clothes clip comprises: a first clamping portion 11, a second clamping portion 12 pivotally connected to the first clamping portion 11 through a pivot 2, a first ring body 13 arranged on the first clamping portion 11, a second ring body 14 arranged on the second clamping portion 12 and used to abut against the first ring body 13 to clamp the object to be clamped, and an elastic member 3 connecting the first clamping portion 11 and the second clamping portion 12 and used to pull the first ring body 13 close to the second ring body 14; when the first ring body 13 abuts against the second ring body 14, the first clamping portion 11, the second clamping portion 12, the first ring body 13 and the second ring body 14 enclose a clamping space 4.

[0030] In this way, the first clamping part 11 is pivotally connected to the second clamping part 12 through the pivot 2, and the first clamping part 11 and the second clamping part 12 can rotate relative to each other; the first clamping part 11 and the second clamping part 12 are pulled by the elastic member 3 to enable the first ring body 13 and the second ring body 14 to clamp the object to be clamped. During the relative rotation of the first clamping part 11 and the second clamping part 12, when the first ring body 13 on the first clamping part 11 abuts / approaches the second ring body 14 on the second clamping part 12, the object to be clamped can be clamped by the outer side wall of the first ring body 13 and the outer side wall of the second ring body 14 (specifically, in one embodiment, when the first ring body 13 and the second ring body 14 clamp the object to be clamped, the annular first ring body 13 and the second ring body 14 are easy to contact with the object to be clamped of different shapes, so that the object to be clamped is not easy to loosen. Specifically, in one embodiment, when the object to be clamped When an object (such as clothing) is easily deformed when clamped, the contact surfaces of the first ring body 13 and the second ring body 14 with the object to be clamped are in closer contact when the object to be clamped is deformed.) The object to be clamped is not easily scratched when clamped by the first ring body 13 and the second ring body 14; and when a user directly pulls and removes the object to be clamped clamped by the first ring body 13 and the second ring body 14, the object to be clamped is not easily scratched by the first ring body 13 and the second ring body 14; in addition, the first ring body 13 and the second ring body 14 can hang objects themselves (specifically, in one embodiment, when objects are hung on the first ring body 13 and the second ring body 14, the first ring body 13 and the second ring body 14 Under the traction of the gravity of the object, the first ring body 13 and the second ring body 14 are brought closer to each other / abutted against each other, thereby improving the tightness of the first ring body 13 and the second ring body 14 in clamping the object to be clamped; or the first ring body 13 and the second ring body 14 are tied together, thereby improving the tightness of the first ring body 13 and the second ring body 14 in clamping the object to be clamped.); When the first ring body 13 and the second ring body 14 clamp the object to be clamped, the first ring body 13 and the second ring body 14 can increase the clamping force of the object to be clamped under the traction of the elastic member 3, and it is not easy to loosen; when the first ring body 13 and the second ring body 14 clamp the object to be clamped, the first clamping part 11, the second clamping part 12, the first ring body 13 and the second ring body 14 enclose to form a clamping space 4, which can accommodate part of the object to be clamped, and even if part of the object to be clamped clamped by the first ring body 13 and the second ring body 14 is loose, the object to be clamped in the clamping space 4 can be clamped by the first clamping part 11 and the second clamping part 12, thereby reducing the possibility of the object to be clamped falling.

[0031] Specifically, in one embodiment, a first through hole 113 is formed on the first clamping portion 11, and a second through hole 123 is formed on the second clamping portion 12; the elastic member 3 is respectively inserted into the first through hole 113 and the second through hole 123. In this way, the elastic member 3 passes through the first through hole 113 and the second through hole 123, and the first through hole 113 and the second through hole 123 can limit the elastic member 3 and prevent the elastic member 3 from excessive deformation.

[0032] For further information, see Figures 1 to 6 As a specific embodiment of the clothespin provided by the present invention, a sub-cavity 41 located in the clamping space 4 is formed between the outer wall of the first ring body 13 and the outer wall of the second ring body 14; in the direction away from the contact portion (contact portion: the contact position of the first ring body 13 and the second ring body 14 when no object is clamped), the width of the sub-cavity 41 gradually increases. In this way, when the object to be clamped in the sub-cavity 41 moves along the gap between the first ring body 13 and the second ring body 14 to the clamping position (clamping position, i.e., the contact portion of the first ring body 13 and the second ring body 14 when no object is clamped) of the first ring body 13 and the second ring body 14, it encounters a narrower and narrower gap, which reduces the possibility of the object to be clamped in the sub-cavity 41 being loosened from between the first ring body 13 and the second ring body 14.

[0033] For further information, see Figures 1 to 6 As a specific embodiment of the clothespin provided by the present invention, a first boss 115 is provided on the first clamping portion 11 in the clamping space 4, and a U-shaped groove 116 is provided on the first boss 115; a second boss 125 is provided on the second clamping portion 12 in the clamping space 4, and a pivot 2 inserted in the U-shaped groove 116 is provided on the second boss 125. In this way, the pivot 2 is inserted in the U-shaped groove 116 and can rotate relative to the U-shaped groove 116. (Specifically, in one embodiment, the second clamping portion 12 is connected to the pivot 2 through the opening of the U-shaped groove 116; because the second clamping portion 12 is connected to the pivot 2 through the opening of the U-shaped groove 116, when the pivot 2 rotates in the U-shaped groove 116, the two end edges of the opening of the U-shaped groove 116 can limit the rotation angle of the pivot 2;) the U-shaped groove 116 can be supported by the first boss 115, and the pivot 2 can be supported by the second boss 125.

[0034] Specifically, in one embodiment, in the cross section of the U-shaped groove 116, the inner wall of the U-shaped groove 116 is circular. Specifically, in one embodiment, the inner diameter of the U-shaped groove 116 is the same as the outer diameter of the pivot 2. Specifically, in one embodiment, in the cross section of the U-shaped groove 116, the curvature of the inner wall of the U-shaped groove 116 is greater than 180°; in this way, the pivot 2 is prevented from detaching from the opening of the U-shaped groove 116 along the radial direction of the pivot 2 from the U-shaped groove 116. Specifically, in one embodiment, in the cross section of the U-shaped groove 116, the curvature of the inner wall of the U-shaped groove 116 is less than 300°

[0035] Specifically, in one embodiment, each part of the inner wall of the first ring body 13 is smoothly connected, and / or each part of the inner wall of the second ring body 14 is smoothly connected. In this way, when an external object is hung on the first ring body 13, it is not easy to scratch the inner wall of the first ring body 13; when an external object is hung on the second ring body 14, it is not easy to scratch the inner wall of the second ring body 14.

[0036] Specifically, in one embodiment, the outer surface of the first ring body 13 is smoothly connected to the outer surface of the first clamping portion 11, and / or the outer surface of the second ring body 14 is smoothly connected to the outer surface of the second clamping portion 12. In this way, the object to be clamped in the clamping space 4 slides along the first clamping portion 11 to the first ring body 13 more smoothly and is not easily scratched; the object to be clamped in the clamping space 4 slides along the second clamping portion 12 to the second ring body 14 more smoothly and is not easily scratched.

[0037] Specifically, in one embodiment, a U-shaped groove 116 is provided on the first clamping portion 11 for the pivot 2 to be inserted into; the inner wall of the U-shaped groove 116 abuts against and wraps around the outer surface of the pivot 2. In this way, the pivot 2 can maintain close contact with the U-shaped groove 116.

[0038] Specifically, in one embodiment, the first boss 115 is located between the first clamping portion 11 and the second clamping portion 12; and / or the second boss 125 is located between the first clamping portion 11 and the second clamping portion 12. In this way, the first boss 115 can be protected by the first clamping portion 11 and the second clamping portion 12, reducing interference of external objects on the first boss 115; the second boss 125 can be protected by the first clamping portion 11 and the second clamping portion 12, reducing interference of external objects on the second boss 125.

[0039] Specifically, in one embodiment, the first ring body 13 and the first clamping portion 11 are integrally formed, and / or the second ring body 14 and the second clamping portion 12 are integrally formed. In this way, the first ring body 13 and the first clamping portion 11 are more firmly connected, and the second ring body 14 and the second clamping portion 12 are more firmly connected.

[0040] Specifically, in one embodiment, the first clamping portion 11 , the first ring body 13 , the second clamping portion 12 and the second ring body 14 are respectively made of aluminum alloy materials.

[0041] For further information, see Figures 1 to 6 As a specific embodiment of the clothespin provided by the present invention, one end of the elastic member 3 is connected to the intersection of the first ring body 13 and the first clamping part 11, and the other end of the elastic member 3 is connected to the intersection of the second ring body 14 and the second clamping part 12. In this way, the strength of the intersection of the first ring body 13 and the first clamping part 11 is relatively high, and the intersection of the first ring body 13 and the first clamping part 11 is not easily deformed by the elastic member 3; the strength of the intersection of the second ring body 14 and the second clamping part 12 is relatively high, and the intersection of the second ring body 14 and the second clamping part 12 is not easily deformed by the elastic member 3.

[0042] For further information, see Figures 1 to 6As a specific embodiment of the clothespin provided by the present invention, the first clamping portion 11 has a first surface 111 facing the second clamping portion 12 and a second surface 112 facing away from the second clamping portion 12; the second clamping portion 12 has a third surface 121 facing the first clamping portion 11 and a fourth surface 122 facing away from the first clamping portion 11; the second surface 112 and the outer wall of the first ring body 13 form a first groove 15 with an opening facing away from the second ring body 14, and one end of the elastic member 3 abuts on the inner wall of the first groove 15; the fourth surface 122 and the outer wall of the second ring body 14 form a second groove 16 with an opening facing away from the first ring body 13, and the other end of the elastic member 3 abuts on the inner wall of the second groove 16. In this way, when the elastic member 3 abuts in the first groove 15 and pushes the first ring body 13 toward the second ring body 14, it is not easy to disengage from the first groove 15; when the elastic member 3 abuts in the second groove 16 and pushes the second ring body 14 toward the first ring body 13, it is not easy to disengage from the second groove 16.

[0043] Specifically, in one embodiment, the cross section of the first groove 15 is V-shaped or U-shaped, and / or the cross section of the second groove 16 is V-shaped or U-shaped.

[0044] For further information, see Figures 1 to 6 As a specific embodiment of the clothespin provided by the present invention, the inner wall of the first groove 15 is recessed to form a first positioning groove 151, and one end of the elastic member 3 is clamped in the first positioning groove 151; the inner wall of the second groove 16 is recessed to form a second positioning groove 161, and the other end of the elastic member 3 is clamped in the second positioning groove 161. In this way, one end of the elastic member 3 is clamped in the first positioning groove 151, and the first positioning groove 151 limits one end of the elastic member 3; the other end of the elastic member 3 is clamped in the second positioning groove 161, and the second positioning groove 161 limits one end of the elastic member 3.

[0045] Specifically, in one embodiment, the extension direction of the first positioning groove 151 is parallel to the extension direction of the pivot 2, and / or the extension direction of the second positioning groove 161 is parallel to the extension direction of the pivot 2. In this way, when the first clamping portion 11 and the second clamping portion 12 rotate relative to each other, the elastic member 3 is deformed, and since the first positioning groove 151 is parallel to the pivot 2, the elastic member 3 is not easy to slide out of the first positioning groove 151 during the bending process in the plane perpendicular to the pivot 2; when the first clamping portion 11 and the second clamping portion 12 rotate relative to each other, the elastic member 3 is deformed, and since the second positioning groove 161 is parallel to the pivot 2, the elastic member 3 is not easy to slide out of the second positioning groove 161 during the bending process in the plane perpendicular to the pivot 2.

[0046] For further information, see Figures 1 to 6As a specific embodiment of the clothespin provided by the present invention, when the first ring body 13 abuts against the second ring body 14, the plane passing through the axis of the pivot 2 and the contact point between the first ring body 13 and the second ring body 14 is set as a predetermined plane, and the first ring body 13 and the second ring body 14 are symmetrically arranged on opposite sides of the predetermined plane. In this way, when the first ring body 13 and the second ring body 14 clamp the object to be clamped from both sides, the forces on both sides of the object to be clamped are more consistent.

[0047] For further information, see Figures 1 to 6 As a specific embodiment of the clothespin provided by the present invention, the inner wall of the first ring body 13 close to the pivot 2 is the first inner wall, the inner wall of the first ring body 13 away from the pivot 2 is the second inner wall, and the radius of curvature of each location on the second inner wall is greater than the radius of curvature of each location on the first inner wall; and / or the inner wall of the second ring body 14 close to the pivot 2 is the third inner wall, the inner wall of the second ring body 14 away from the pivot 2 is the fourth inner wall, and the radius of curvature of each location on the fourth inner wall is greater than the radius of curvature of each location on the third inner wall. In this way, the curvature radius of the second inner wall on the first ring body 13 away from the pivot 2 is larger than the curvature radius of the first inner wall on the first ring body 13 close to the pivot 2, which is convenient for external objects to be hung on the second inner wall and reduce the sliding of external objects relative to the first ring body 13; the curvature radius of the fourth inner wall on the second ring body 14 away from the pivot 2 is larger than the curvature radius of the third inner wall on the second ring body 14 close to the pivot 2, which is convenient for external objects to be hung on the fourth inner wall and reduce the sliding of external objects relative to the second ring body 14.

[0048] For further information, see Figures 1 to 6 As a specific embodiment of the clothespin provided by the present invention, a first stopper 21 is provided at one end of the pivot 2, a second stopper 22 is provided at the other end of the pivot 2, an edge of one end of the U-shaped groove 116 abuts on the first stopper 21, and an edge of the other end of the U-shaped groove 116 abuts on the second stopper 22; an assembly hole along the axis of the pivot 2 is provided on the pivot 2, and a rod body 23 inserted in the assembly hole is provided on the second stopper 22; one end of the rod body 23 is connected to the second stopper 22, a blind hole 231 is provided on the end surface of the other end of the rod body 23, and a pin body 24 inserted in the blind hole 231 is provided on the first stopper 21. In this way, the pivot 2 can avoid sliding out of the U-shaped groove 116 along the U-shaped groove 116 under the restriction of the first stopper 21 and the second stopper 22; the first stopper 21 can be very conveniently removed from the pivot 2.

[0049] Specifically, in one embodiment, the second stopper 22 and the rod body 23 form a female nail of a rivet. Specifically, in one embodiment, the first stopper 21 and the pin body 24 form a sub-nail of a rivet.

[0050] For further information, see Figures 1 to 6 As a specific embodiment of the clothespin provided by the present invention, the elastic member 3 is a U-shaped spring ring, which is wrapped around the outside of the pivot 2. In this way, the structure is simple and easy to bend; the spring ring can protect the pivot 2, and the spring ring is not easy to collide with the pivot 2 or be limited by the pivot 2 during the process of expansion / contraction.

[0051] Specifically, in one embodiment, the first clamping portion 11 and the first ring body 13 are integrally formed; and / or the second clamping portion 12 and the second ring body 14 are integrally formed. In this way, the first clamping portion 11 and the first ring body 13 are more firmly connected, and the second clamping portion 12 and the second ring body 14 are more firmly connected.

[0052] Specifically, in one embodiment, the elastic member 3 is an elastic strip.

[0053] Specifically, in one embodiment, the cross section of the elastic member 3 is circular. In this way, the elastic strip is easy to process, and if the elastic strip rotates around the extension direction, it is not easy to bump against the object to be clamped.

[0054] Specifically, in one embodiment, the first through hole 113 is a strip-shaped hole, and / or the second through hole 123 is a strip-shaped hole.
