A concealed rope buckle

Abstract

This invention discloses a concealed rope buckle, specifically relating to the field of fastener product technology. It includes a face buckle assembly, a buckle core device, a buckle shell device, and a fabric device. The face buckle assembly includes a panel with a connecting rod installed at the bottom. A fixing frame is installed inside the connecting rod. Two symmetrical connecting frames (first type) are connected to both ends of the fixing frame. One end of each of the two connecting frames (first type) is connected to a connecting frame (second type). A positioning plate is installed on one side of each of the two connecting frames (second type). The snap-fit ​​design allows the positioning plate to be precisely engaged in the first and second holes of the buckle core device by pulling and releasing the pull plate after the connecting rod is inserted into the first hole of the buckle core device. This snap-fit ​​structure better disperses the pulling and shaking forces on the connecting rod, evenly distributing the external forces on the contact surfaces of the positioning plate and the first and second holes. This greatly enhances the stability of the connection between the connecting rod and the buckle core device, effectively preventing the connecting rod from falling off due to reduced friction.

Description

Technical Field

[0001] This invention relates to the field of fastener technology, and more specifically, to a concealed rope buckle. Background Technology

[0002] Currently, rope buckles are generally used to adjust the tightness of ropes on tents, backpacks, or clothing. However, existing rope buckles have complex structures, require complicated winding processes, and are completely exposed outside the fabric of clothing, affecting mobility and aesthetics.

[0003] A search revealed a rope buckle in publication number CN207269985U, comprising a face buckle, a core buckle, and a shell buckle connected in sequence. The face buckle includes a panel with a connecting rod on the side facing the core buckle. A first hole is provided in the middle of the upper sidewall of the core buckle, and the connecting rod is interference-fitted with the first hole. The shell buckle has an opening at its upper part and a cavity inside the shell. The opening communicates with the cavity. The core buckle is inserted into the cavity of the shell buckle through the opening, and the shell buckle and the core buckle are connected by an elastic limiting connection mechanism. The front and rear sidewalls of the shell buckle have rope holes, and the front and rear sidewalls of the core buckle have rope grooves corresponding to the rope holes. This rope buckle has a simple and reasonable structure, which can hide and fix the shell buckle and the core buckle inside the clothing fabric, preventing the rope from being exposed and interfering with limb movement, thus improving the practicality and aesthetics of the rope buckle.

[0004] In the aforementioned patent, the connecting rod is interference-fitted with the first hole. However, since the interference fit mainly relies on the friction between the connecting rod and the hole wall to achieve the connection, during long-term use, it is subjected to frequent pulling, shaking and other external forces. This friction is likely to gradually decrease, causing the connection between the connecting rod and the first hole to become unstable. Subsequently, the connecting rod may fall out of the first hole, thus affecting the normal use of the rope buckle. Therefore, we propose a concealed rope buckle. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a concealed rope buckle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a concealed rope buckle, comprising a face buckle assembly, a buckle core device, a buckle shell device, and a fabric device. The face buckle assembly includes a panel, a connecting rod installed at the bottom of the panel, a fixing frame installed inside the connecting rod, two symmetrical connecting frames 1 connected to both ends of the fixing frame, a connecting frame 2 connected to one end of each of the two connecting frames 1, and a positioning plate installed on one side of each of the two connecting frames 2.

[0007] Preferably, the connecting rod has two symmetrical positioning grooves on its outside, and the positioning plate is located inside the positioning grooves.

[0008] Preferably, the top of the panel is provided with a slot 1 and a slot 2, the slot 1 and the slot 2 are connected, and the depth of the slot 1 is greater than the depth of the slot 2. A spring 1 is installed inside the slot 1.

[0009] Preferably, a connecting plate is installed on the top of the spring one, the connecting plate is located inside the slot two, and the size of the connecting plate is adapted to the size of the slot two.

[0010] Preferably, the connecting plate has a groove inside, and a pull plate is installed inside the groove. Pulling the pull plate moves the connecting plate.

[0011] Preferably, a connecting column is installed at the bottom of the connecting plate, and a connecting seat is installed at the bottom end of the connecting column. The connecting column slides inside the fixed frame.

[0012] Preferably, the external connection of the connecting seat has two symmetrical connecting frames three, and the connecting frame three is connected to the connecting frame two.

[0013] Preferably, the bottom of the panel is provided with several sets of anti-slip teeth distributed in a circumferential pattern, and the anti-slip teeth are conical.

[0014] The technical effects and advantages of this invention are as follows: In use, the snap-fit ​​design of this invention allows the positioning plate to be precisely locked into the first and second holes of the buckle device by pulling and releasing the pull plate after the connecting rod is inserted into the first hole of the buckle device. This snap-fit ​​structure can better disperse the external forces such as pulling and shaking on the connecting rod, and distribute the external forces evenly on the contact surfaces of the positioning plate and the first and second holes. This greatly enhances the stability of the connection between the connecting rod and the buckle device, effectively avoids the problem of the connecting rod falling off due to reduced friction, and ensures that the rope buckle can operate reliably in various usage scenarios.

[0015] When in use, this invention reduces wear between components through innovative designs such as snap-fit ​​structures and anti-slip teeth, ensuring the normal operation of each component. At the same time, the concealed design reduces the contact between the rope buckle and the external environment, reducing damage to the product caused by external factors (such as dust, moisture, etc.), further extending the product's service life and saving users the cost of product replacement. Furthermore, the panel, connecting plate, and pull plate are all on the same horizontal plane, preventing any protruding structure from causing discomfort to the user. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] As attached Figures 1-5 The concealed rope buckle shown includes a face buckle assembly 1, a buckle core device 2, a buckle shell device 3, and a fabric device 5. The face buckle assembly 1 includes a panel 11, a connecting rod 12 is installed at the bottom of the panel 11, and several sets of anti-slip teeth 13 distributed in a circular pattern are installed at the bottom of the panel 11. The anti-slip teeth 13 are conical. A fixing frame 14 is installed inside the connecting rod 12. Two symmetrical connecting frames 15 are connected to both ends of the fixing frame 14. A connecting frame 2 16 is connected to one end of each of the two connecting frames 15. A positioning plate 17 is installed on one side of each of the two connecting frames 2 16. Two symmetrical positioning grooves 18 are formed on the outside of the connecting rod 12. The positioning plate 17 is located inside the positioning grooves 18. The top of the panel 11 is provided with a first groove 19 and a second groove 110. The first groove 19 and the second groove 110 are connected, and the depth of the first groove 19 is greater than the depth of the second groove 110. A spring 111 is installed inside the first groove 19. A connecting plate 112 is installed on the top of the spring 111. The connecting plate 112 is located inside the second groove 110, and the size of the connecting plate 112 is similar to that of the groove. The dimensions of the second type 110 are compatible. The inside of the connecting plate 112 is provided with a groove 113. A pull plate 114 is installed inside the groove 113. By pulling the pull plate 114, the connecting plate 112 is moved. A connecting post 115 is installed at the bottom of the connecting plate 112. A connecting seat 116 is installed at the bottom end of the connecting post 115. The connecting post 115 slides inside the fixed frame 14. The outside of the connecting seat 116 is connected to two symmetrical connecting frames 117. The connecting frames 117 are connected to the connecting frame 16. As the part that comes into direct contact with the outside world, the design of the panel 11 is not only related to aesthetics but also affects the user experience. The connecting rod 12 is a key component for connection. The connecting rod 12 has a hollow structure and acts as a bridge, transmitting the operation of the face buckle assembly 1 to the buckle core device 2, thereby realizing the tightening and loosening function of the rope. Several sets of anti-slip teeth 13 are designed in a conical shape. This unique shape can greatly increase the friction with the contact surface when in contact with clothing and other surfaces, ensuring that the rope buckle is not easy to slip during use and improving the stability of use. The fixed frame 14 provides stable support for the entire transmission structure. The fixed frame 14 is installed inside the connecting rod 12 and is connected to the positioning plate 17 through the first connecting frame 15 and the second connecting frame 16, as well as the setting of the third connecting frame 117, to form a stable transmission structure. When the pull plate 114 is pulled upward, the positioning plate 17 moves to the position of the positioning groove 18 through this series of transmission structures until the positioning plate 17 is located inside the connecting rod 12, providing a basis for the subsequent snap-fit ​​operation and ensuring the accurate insertion of the subsequent connecting rod 12. After the connecting rod 12 is in the correct position, the pull plate 114 is released, and the positioning plate 17 is reset by the setting of the first spring 111. The positioning plate 17 is then snapped into the first hole and the second hole set at the buckle device 2. The first spring 111 provides power for the reset of the connecting plate 112. Using the fabric and mounting holes of the fabric device 5, the entire rope buckle is installed. The buckle shell device 3 is wrapped around the outer structure of the buckle core device 2 and the face buckle assembly 1, so that the entire rope buckle is hidden and fixed inside the clothing fabric, preventing the rope from being exposed and interfering with limb movement, thus improving the practicality and aesthetics of the rope buckle. Panel 11, connecting plate 112 and pull plate 114 are on the same horizontal plane to prevent any protruding structure from causing discomfort to the user.

[0024] Working principle of the present invention: The fastener core device 2, the fastener shell device 3, and the fabric device 5 are all existing structures as disclosed in CN207269985U. The fastener core device 2 includes: a fastener core, a cord threading groove, a first hole, a second hole, a protrusion, and a compression spring; the fastener shell device 3 includes: a fastener shell, a cord threading hole, and a sliding groove; the fabric device 5 includes: fabric and mounting holes. Specific embodiments are not described in detail here. Before assembly, pull the pull plate 114 upward. The pull plate 114 is installed in the groove 113 inside the connecting plate 112. Pulling the pull plate 114 will drive the connecting plate 112 to move upward in the slot 110. The bottom of the connecting plate 112 is connected to the connecting post 115. The connecting post 115 slides in the fixing frame 14. When the pull plate 114 is pulled, the connecting seat 116 moves. At this time, the connecting seat 116 drives the connecting frame 16 to move through the connecting frame 117. Through this series of transmission structures, the positioning plate 17 will be positioned in the connecting rod 12 through the positioning groove 18, which is ready for the subsequent accurate insertion of the connecting rod 12 into the buckle device 2. Insert the prepared connecting rod 12 into the first hole of the buckle device 2. After the connecting rod 12 is in place, release the pull plate 114. At this time, the spring 111 installed in the slot 19 will release elastic potential energy, pushing the connecting plate 112 to move downward and reset. The resetting of the connecting plate 112 will drive the connecting column 115, connecting seat 116, connecting frame 3 117, and connecting frame 2 16 to move, thereby resetting the positioning plate 17. The reset positioning plate 17 is locked in the first and second holes set in the buckle device 2. Compared with the traditional interference fit, this locking method can better disperse the external forces such as pulling and shaking that the connecting rod 12 is subjected to, greatly enhancing the stability of the connection between the connecting rod 12 and the buckle device 2, and avoiding the phenomenon that the connecting rod 12 will fall out of the first hole due to the reduction of friction.
