Description

Technical Field

[0001] The utility model relates to the field of snap fasteners, in particular to an anti-loosening snap fastener. Background Art

[0002] Snap buttons are a common clothing accessory, typically used to secure collars, cuffs, pockets, and other areas of clothing. They consist of four cooperating components: a face button, a female button, a sub-button, and a spike. Their simple yet practical design provides excellent fastening while also adding a decorative touch. Snap buttons are widely used in clothing production and everyday wear.

[0003] In existing technology, snap fasteners typically use an S-shaped spring to provide the snapping force. When the snap fastener presses against the face buckle, the female buckle compresses the spring. Once the snap fastener is engaged, the spring returns to its original position, locking the female buckle into the male buckle. Each press and tightening operation causes some damage to the spring. Over time, the spring loses its elasticity, causing the snap fastener to become loose and difficult to fasten, or even to fail to fasten. Summary of the Invention

[0004] In view of this, the utility model provides an anti-loosening snap fastener which has reliable connection and is not easy to loosen.

[0005] A snap-on buckle for preventing loosening comprises a face buckle, a female buckle fixedly connected to the face buckle, a male buckle configured to match the female buckle, and a spike for securing the male buckle. The female buckle comprises a female buckle body, a connecting groove provided on one side of the female buckle body, a mounting groove provided on the side of the female buckle body opposite the connecting groove, a position-limiting support provided within the mounting groove, and an elastic member provided within the mounting groove. The mounting groove comprises a sliding groove and a locking groove provided on one side of the sliding groove. The male buckle comprises a male buckle body and a plug-in post provided on one side of the male buckle body. When the male buckle engages with the female buckle, the plug-in post slides from the sliding groove into the locking groove along the elastic member. At this point, one side of the elastic member abuts the position-limiting support and the other side abuts the plug-in post, thereby securing the plug-in post within the locking groove.

[0006] Furthermore, the plug-in column includes a plug-in column body and a plug-in limiting portion fixedly arranged at one end of the plug-in column body.

[0007] Furthermore, the sliding groove and the locking groove are communicated with each other, and the locking groove matches the plug-in column.

[0008] Furthermore, the position-limiting support platform includes a support platform body and an avoidance groove arranged between the support platform body and the female buckle body.

[0009] Furthermore, one end of the elastic member is fixedly connected to the female buckle body on one side of the sliding groove, and the other end of the elastic member extends into the locking groove.

[0010] Furthermore, the elastic member is a Z-shaped spring piece.

[0011] Furthermore, the opening diameter of the locking groove is smaller than the diameter of the plug-in limiting portion of the plug-in column.

[0012] Furthermore, the connecting groove is an annular groove provided on the female buckle body.

[0013] Compared with the prior art, the anti-loosening snap fastener provided by the present invention has a female buckle including the mounting groove, a limiting support provided in the mounting groove, and an elastic member provided in the mounting groove. The mounting groove includes a sliding groove and a locking groove provided on one side of the sliding groove. When the male buckle is engaged with the female buckle, the plug-in post slides from the sliding groove into the locking groove along the elastic member. The opening diameter of the locking groove is smaller than the diameter of the plug-in limiting portion. At the same time, one side of the elastic member abuts against the limiting support, and the other side abuts against the plug-in post, thereby fixing the plug-in post in the locking groove, so that the anti-loosening snap fastener will not easily loosen or separate when engaged.

[0018] like Figures 1 to 3As shown, it is the structure schematic diagram of the anti-loosening four-way buckle provided by the utility model. The anti-loosening four-way buckle comprises a surface buckle 10, a female buckle 20 fixedly connected with the surface buckle 10, a male buckle 30 matched with the female buckle 10, and a long nail 40 for fixing the male buckle 30. It is conceivable that the anti-loosening four-way buckle should also comprise some other functional components, such as assembly components, decoration components and the like, which are all prior art known by those skilled in the art and will not be described here.

[0019] The surface buckle 10 is the visible part of the anti-loosening four-way buckle in use, and the surface buckle 10 is used for fixing the female buckle 20 and has a certain decoration effect. The surface buckle 10 is installed in pairs with the female buckle 20, so as to fix the female buckle 20 on clothes. The surface buckle 10 comprises a surface buckle main body 11 and a plurality of connecting claws 12 fixedly arranged on one side of the surface buckle main body 11. The surface buckle main body 11 is usually circular in design, or designed into other shape structures according to aesthetic needs. Preferably, patterns or patterns can be arranged on the surface buckle main body 11 as decoration, so that the four-way buckle has a certain decoration while having a fastening function. The connecting claws 12 are arranged at equal intervals on the surface buckle main body 11 and arranged in a circular shape. The connecting claws 12 are used to connect the surface buckle 10 and the female buckle 20 together. The surface buckle 10 itself is prior art known by those skilled in the art and will not be described here.

[0020] The female buckle 20 comprises a female buckle main body 21, a connecting groove 22 arranged on one side of the female buckle main body 21, an installation groove 23 arranged on the side of the female buckle main body 21 opposite to the connecting groove 22, a limiting support 24 arranged in the installation groove 23, and an elastic member 25 arranged in the installation groove 22.

[0021] The connecting groove 22 is an annular groove arranged on the female buckle main body 21. The connecting groove 22 is used to install the surface buckle 10, so as to install the surface buckle 10 and the female buckle 20 together and fixed on the connecting object. When the surface buckle 10 and the female buckle 20 are installed, one end of the connecting claw 12 is inserted into the connecting groove 22, and the surface buckle main body 11 is pressed to make the connecting claw 12 bend, so as to hold the female buckle main body 21, so as to buckle the surface buckle 10 and the female buckle 20 together.

[0022] The mounting groove 23 includes a sliding groove 231 and a locking groove 232 provided on one side of the sliding groove 231. The sliding groove 231 and the locking groove 232 are connected to each other. The diameter of the sliding groove 231 is larger than that of the locking groove 232, so as to facilitate the insertion of the male buckle 30 into the mounting groove 23, which will be described in detail below in conjunction with the male buckle 30. The shape of the locking groove 232 is matched with the shape of the plug-in column 32 described below of the male buckle 30, and the opening diameter of the locking groove 232 is smaller than the diameter of the plug-in limit portion 322 of the plug-in column 32, so that the male buckle 30 can be snapped into the locking groove 232 after sliding into the locking groove 232 along the elastic member 25 from one side of the sliding groove 231.

[0023] The limiting support 24 includes a support body 241 and an avoidance groove 242 arranged between the support body 241 and the female buckle body 21. The support body 241 is arranged on one side of the locking groove 232 of the mounting groove 23, and the support body 241 intersects with the sliding groove 231, and the avoidance groove 242 is formed between the connection of the elastic member 25 and the female buckle body 21. The support body 241 is used to support the elastic member 25, and cooperate with the elastic member 25 to complete the buckling and locking action when the male buckle 30 is buckled into the mounting groove 23. The avoidance groove 242 is used to form a gap when the male buckle 30 slides out of the mounting groove 23 and pushes the elastic member 25 to compress, so as to facilitate the male buckle 30 to slide out of the mounting groove 23.

[0024] The elastic member 25 is a tilted Z-shaped spring. One end of the elastic member 25 is fixedly connected to the female buckle body 21 on one side of the sliding slot 231, and the other end of the elastic member 25 extends into the locking slot 232. When the male buckle 30 is engaged with the female buckle 20, one corner of the Z-shaped elastic member 25 abuts the limiting support 24, while the other corner abuts the male buckle 30, thereby securing the male buckle 30 in the locking slot 232 under the action of the elastic force.

[0025] The male buckle 30 includes a male buckle body 31 and an inserting post 32 disposed on one side of the male buckle body 31 .

[0026] The male buckle body 31 is used to set the plug column 32. It is conceivable that a mounting hole for connecting with the long nail 40 is further provided on the side of the male buckle body 31 opposite to the plug column 32, thereby facilitating the connection of the male buckle 30 with the long nail 40.

[0027] The plug-in column 32 is used to cooperate with the mounting groove 23 to achieve buckling, and the plug-in column 32 matches the locking groove 232. The plug-in column 32 includes a plug-in column body 321, and a plug-in limit portion 322 fixedly arranged at one end of the plug-in column body 321. One end of the plug-in column body 321 is fixedly connected to the male buckle body 31, and the other end is fixedly connected to the plug-in limit portion 322. The diameter of the plug-in column body 321 is smaller than the distance between the two intersection points of the sliding groove 231 and the locking groove 232, so that the plug-in column 32 can slide smoothly from the sliding groove 231 into the locking groove 232.

[0028] The diameter of the insertion limit portion 322 is larger than the diameter of the insertion post body 321. When the male buckle 30 is engaged with the female buckle 20, the limit portion 322 slides from the sliding groove 231 along the elastic member 25 into the locking groove 232. The elastic member 25 abuts the insertion limit portion 322 and, under the action of elastic force, secures the insertion limit portion 322 within the locking groove 232 together with the female buckle body 21, thereby engaging the female buckle 20 and the male buckle 30. The male buckle 30 itself is well known to those skilled in the art and will not be described in detail here.

[0029] The long spike 40 is arranged in pairs with the male buckle 30, and the long spike 40 is used to install and fix the male buckle 30. The long spike 40 itself is a prior art and will not be described in detail here.

[0030] When the anti-loosening snap fastener is engaged, the plug-in post 32 is aligned with the sliding slot 231, and the elastic member 25 is pressed downward to cause the plug-in limiting portion 322 to slide into the locking slot 232. At this time, under the elastic force of the elastic member 25, the plug-in post 32 is fixedly engaged in the locking slot 232. When the anti-loosening snap fastener is to be opened, the male buckle 30 is pressed to push the elastic member 25 downward and compress it toward one side of the sliding slot 231. At the same time, the plug-in limiting portion 322 slides into the sliding slot 231 and disengages from the mounting slot 23 to complete the opening operation.

[0031] Compared with the prior art, the anti-loosening snap fastener provided by the present invention has a female buckle 20 comprising a mounting groove 23, a limiting support 24 disposed in the mounting groove 23, and an elastic member 25 disposed in the mounting groove 23. The mounting groove 23 comprises a sliding groove 231 and a locking groove 232 disposed on one side of the sliding groove 231. When the male buckle 30 is fastened with the female buckle 20, the plug-in post 32 slides from the sliding groove 231 into the locking groove 232 along the elastic member 25. The opening diameter of the locking groove 232 is smaller than the diameter of the plug-in limiting portion 322. At the same time, one side of the elastic member 25 abuts against the limiting support 24, and the other side abuts against the plug-in post 32, thereby fixing the plug-in post 32 in the locking groove 232, so that the anti-loosening snap fastener will not easily loosen or separate when fastened.
