Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and in particular to a novel fastener that integrates male and female components. Background Technology

[0002] Currently, there are various types and styles of backpack buckles on the market. Their function is to fasten the backpack straps that pass through the buckles, thereby adjusting the length of the backpack straps to meet the needs of people of different heights.

[0003] For example, a backpack buckle as described in Chinese utility model CN201822270621.8 includes a male buckle and a female buckle that interlock. The male buckle has elastic prongs on both sides, and the outer end of each prong has a snap-fit ​​part. The female buckle has an insertion cavity opened along the insertion direction. One end of the insertion cavity is an insertion port, and the other end of the insertion cavity has snap-fit ​​openings on both sides that engage with the snap-fit ​​parts of the corresponding prongs. The male buckle has a guide tongue between the two prongs. The prongs have hollow holes, and the guide tongue has guide protrusions on both sides. The length of the guide protrusions extends along the insertion direction. The female buckle has a guide groove corresponding to the guide protrusions.

[0004] Conventional fasteners typically consist of a male and a female buckle, each with a corresponding locking mechanism. This requires the use of two different molds during injection molding, and the molds must be precise enough to ensure that the produced male and female buckles fit together perfectly. This places high demands on the precision of the manufacturing process, and care must be taken to prevent incorrect snapping during use, making them somewhat inconvenient to use. Summary of the Invention

[0005] In view of this, the present invention provides a novel male and female integrated fastener to solve the above-mentioned technical problems.

[0006] A novel male-female integrated fastener includes a fastener body, a fastening portion disposed on the fastener body, an insertion portion disposed on one side of the fastening portion, and a connecting buckle disposed on the fastener body. The fastening portion includes a fastening body disposed on the fastener body, a stop block disposed on one side of the fastening body, two locking blocks disposed on both sides of the stop block, and an elastic piece disposed on the other side of the fastening body away from the stop block. The stop block and the two locking blocks are sequentially overlapped, with the two locking blocks located on both sides of the thickness direction of the stop block, which is perpendicular to the protrusion direction of the fastening body. The midpoint of the inclined surface of the stop block coincides with the centerline of the fastener. The two locking blocks are axially symmetrically disposed on both sides of the stop block, and each locking block is a hook-shaped structure with the hook-shaped portion protruding from the edge of the inclined surface of the stop block in a direction away from the fastening body. The elastic piece is disposed on the side of the fastening body away from the abutting inclined block. One end of the elastic piece is connected to the fastening body, and the other end extends freely in a direction away from the fastening body, and is spaced apart from the fastening body. The insertion part includes an insertion body disposed on the fastener body, an insertion port disposed within the insertion body, and a pressing part disposed on the insertion body. The insertion body is disposed on one side of the fastening part, and is located on the side of the fastening body away from the elastic piece. The insertion body is an insertion cavity, with an opening on the side near the fastening body and on the side facing the insertion direction, and an S-shaped edge is provided at the opening. The pressing part is disposed on the outer wall of the insertion body away from the fastening part.

[0007] Furthermore, the main body of the buckle is made of plastic injection molding and is integrally formed with the fastening part, the insertion part and the connecting buckle.

[0008] Furthermore, the fastening body is a protruding structure provided on the fastener body, and the protrusion direction is consistent with the insertion direction of the fastener when fastening.

[0009] Furthermore, the locking block has an arc-shaped guide structure on its free end located in the extension direction of the fastening body.

[0010] Furthermore, the pressing part is configured as an arc-shaped concave surface and has multiple regularly arranged dots.

[0011] Furthermore, the connecting buckle is located at the end of the buckle body away from the buckle insertion direction.

[0012] Furthermore, the abutting inclined block is inclinedly disposed on one side of the fastening body, and the inclination direction forms an acute angle with the protrusion direction of the fastening body.

[0013] Furthermore, the distance from the free end of the elastic sheet to the fastening body is greater than the deformation distance when the locking block is inserted.

[0014] Compared with existing technologies, the novel male-female integrated fastener provided by this utility model eliminates the distinction between male and female fasteners by setting the engagement part and the insertion part. Two identical fasteners can be used, with the engagement part of one fastener inserted into the insertion part of the other fastener, and the two fasteners interlocking and abutting against each other to achieve locking. Furthermore, by setting the elastic piece and the pressing part, pressing the side of the fastener causes the elastic piece to deform, allowing the two engagement parts to be released, thus separating the two fasteners. This achieves the interlocking of two identical fasteners, reduces the types of molds required, and avoids gaps or mismatches between male and female fasteners due to differences in precision.

[0019] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0020] like Figures 1 to 3 The diagram shown is a structural schematic of the novel male-female integrated fastener provided by this utility model. The novel male-female integrated fastener includes a fastener body 10, a fastening part 20 disposed on the fastener body 10, an insertion part 30 disposed on one side of the fastening part 20, and a connecting buckle 40 disposed on the fastener body 10. It is conceivable that the novel male-female integrated fastener also includes other functional modules such as a label disposed on the surface of the buckle, webbing connected to the buckle, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0021] The main body 10 of the fastener can be made of plastic injection molding and is integrally formed with the fastening part 20, the insertion part 30 and the connecting buckle 40, so as to serve as the basic part of the fastener to support and connect the fastening part 20, the insertion part 30 and the connecting buckle 40.

[0022] The fastening part 20 includes a fastening body 21 disposed on the fastener body 10, a stop block 22 disposed on one side of the fastening body 21, two locking blocks 23 disposed on both sides of the stop block 22, and an elastic piece 24 disposed on the other side of the fastening body 21 away from the stop block 22.

[0023] The fastening body 21 is a protruding structure provided on the fastener body 10, and the protrusion direction is consistent with the insertion direction of the fastener when fastening.

[0024] The abutting inclined block 22 and the two locking blocks 23 are arranged in a staggered manner. Specifically, the two locking blocks 23 are located on both sides of the thickness direction of the abutting inclined block 22, which is perpendicular to the protrusion direction of the fastening body 21. The abutting inclined block 22 is inclined on one side of the fastening body 21, and the inclination direction forms an acute angle with the protrusion direction of the fastening body 21. The midpoint of the inclined surface of the abutting inclined block 22 coincides with the center line of the fastener, so that when the two fasteners are inserted and fastened relative to each other, the abutting inclined blocks 22 of the two fasteners abut against each other and the inclined surfaces completely overlap.

[0025] Two locking blocks 23 are symmetrically arranged on both sides of the abutting inclined block 22. Each locking block 23 is a hook-shaped structure, with the hook-shaped portion protruding from the inclined edge of the abutting inclined block 22 in a direction away from the fastening body 21. Thus, when the two fasteners are inserted, the locking blocks 23 of the two fasteners abut against each other, and the fastening body 21 undergoes elastic deformation as it is inserted. When the fasteners are fully inserted, the locking blocks 23 of the two fasteners are in a misaligned state. At this time, the fastening body 21 rebounds under elastic action, and the hook-shaped structures of the locking blocks 23 interlock, achieving mutual locking of the two fasteners and preventing them from separating without external force. Furthermore, an arc-shaped guide structure is provided on the free end of the locking block 23 located in the extension direction of the fastening body 21 to guide the two fasteners when they are inserted together.

[0026] The elastic piece 24 is disposed on the side of the fastening body 21 away from the abutting inclined block 22. One end of the elastic piece 24 is connected to the fastening body 21, and the other end extends freely away from the fastening body 21 and is spaced apart from the fastening body 21, thereby forming a sheet-like structure inclined to the fastening body 21. The distance from the free end of the elastic piece 24 to the fastening body 21 is greater than the deformation distance of the locking block 23 when it is inserted, so that after the fastener is fastened, the elastic piece 24 will abut against the inner wall of the insertion part 30. By pressing the insertion part 30, the fastener can be pushed and the locking blocks 23 of the two fasteners can be separated from each other. The details will be described in detail below with reference to the structure of the insertion part 30.

[0027] The insertion part 30 includes an insertion body 31 disposed on the fastener body 10, an insertion port 32 disposed in the insertion body 31, and a pressing part 33 disposed on the insertion body 31.

[0028] The insertion body 31 is disposed on one side of the fastening part 20 and located on the side of the fastening body 21 away from the elastic piece 24. The insertion body 31 is an insertion cavity, with an opening on the side near the fastening body 21 and on the side facing the insertion direction, so that when the two fasteners are fastened together, the fastening part 20 is inserted into the cavity of the insertion part 30, and an S-shaped edge is provided at the opening, which is a certain distance from the center line of the fastener, so that the edge of the insertion body 31 will not abut against each other after the two fasteners are fastened, thereby reserving movement space for the fasteners to unlock.

[0029] The insertion port 32 is located on the free end of the insertion body 31 away from the connecting buckle 40, so that the fastening part 20 can be inserted therein.

[0030] The pressing part 33 is disposed on the outer side wall of the insertion body 31 away from the fastening part 20. In this embodiment, the pressing part 33 is configured as an arc-shaped concave surface to conform to the curvature of the finger, and is provided with multiple regularly arranged dots to increase the friction of the finger. Correspondingly, other forms of anti-slip structures can also be provided on the pressing part 33, such as multiple parallel stripe-like protrusions, etc., which are not specifically limited here.

[0031] In use, the two fasteners are inserted into each other. The fastening part 20 of one fastener is inserted into the insertion part 30 of the other fastener through the insertion port 32. The fastener abuts against the fastening part 20 of the first fastener and undergoes elastic deformation until the fasteners are fully inserted. The locking blocks 23 of the two fasteners are misaligned and abut against each other. At this time, the elastic pieces 24 of the two fasteners abut against the inner wall of the insertion body 31 of the other fastener. When unlocking is required, the pressing parts 33 of the two fasteners are pressed, causing the elastic pieces 24 to move closer to their respective fastening bodies 21 and undergo elastic deformation. At the same time, the two locking blocks 23 are pushed away from each other in the direction perpendicular to the fastening. When the movement distance of the two locking blocks 23 is greater than the length of the fastening end of the locking block 23, the two fasteners are unlocked.

[0032] The connecting buckle 40 is located at the end of the buckle body 10 away from the buckle insertion direction. It is a common backpack strap length adjustment buckle and is used to adjust the length of the strap. It is existing technology and should be well known to those skilled in the art. Therefore, its structure and function will not be described in detail here.

[0033] The connecting buckle 40 also has an arc-shaped concave surface on its outer edge away from the fastening part 20, so that when the user fastens the two buckles together, the concave surface fits the curvature of the fingers, improving the comfort of use.

[0034] Compared with the prior art, the novel male-female integrated fastener provided by this utility model, by setting the engaging part 20 and the insertion part 30, eliminates the distinction between male and female fasteners. Two identical fasteners can be used, with the engaging part 20 of one fastener inserted into the insertion part 30 of the other fastener, and the two fasteners interlocking and abutting against each other to achieve locking. Furthermore, by setting the elastic piece 24 and the pressing part 33, pressing the side of the fastener causes the elastic piece 24 to deform, thereby disengaging the two engaging parts 20 and allowing the two fasteners to separate. This achieves the interlocking of two identical fasteners, reduces the types of molds required, and avoids gaps or mismatches between male and female fasteners due to differences in precision.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
