Description

Technical Field

[0001] This invention relates to the field of fastener technology, and more specifically, to a highly stable anti-accidental opening hook. Background Technology

[0002] Hooks are commonly used in clothing and other fields. A hook consists of a male hook and a female hook. The female hook has a slot. When fastening, the head of the male hook needs to be aligned with the slot sideways, and then the head of the male hook is pushed into the slot to complete the fastening.

[0003] A novel hook and loop fastener, disclosed in publication number CN222516312U, includes a male and a female hook and loop fastener. The male hook and loop fastener has a buckle head on its front side, with a countersunk hole and a center hole on its front side. A spring bead is placed inside the center hole. The buckle head has a U-shaped outer edge extending outward. A strip groove is provided on the back side of the two parallel sides of the U-shaped outer edge. One end of the strip groove is through and the other end forms a first stepped surface with the U-shaped outer edge. The female hook and loop fastener has a housing on its front side. A slot is provided on one side wall of the housing. A U-shaped slot is provided on the front wall of the housing. A second stepped surface is provided on the inner side of the front wall of the housing near the edge of the U-shaped slot. With this structure, the buckle head enters the housing laterally from the slot in the male hook and loop fastener. The spring bead is compressed and stores energy. After alignment, the male hook and loop fastener are released. The spring bead releases energy, causing the male hook and loop fastener to repel each other axially. This causes the first stepped surface on the buckle head to abut against the second stepped surface on the housing, thereby achieving a self-locking effect and preventing the hook and loop fastener from accidentally disengaging.

[0004] In the aforementioned patent, because the two snaps are too close together, when it is necessary to open them, users often unconsciously pull the garment forcefully in an attempt to widen the gap between the snaps. This excessive pulling can damage the fabric of the garment, causing it to deform, tear, or wrinkle, affecting the appearance and lifespan of the garment. Therefore, we propose a highly stable anti-accidental opening snap. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a highly stable anti-accidental opening hook to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a highly stable anti-accidental opening hook, comprising a male hook seat, a male base plate, a female hook seat, and a female base plate. The bottom of the male base plate is provided with a connecting device one, the top of the female base plate is provided with a connecting device two, the male hook seat is provided with a separation component inside, the top of the female base plate is equipped with two symmetrical fixing seats, the top of the male base plate is provided with a positioning groove, and the fixing seats are provided with limit grooves inside.

[0007] Preferably, the separation component includes a mounting base installed inside the male buckle seat. Two sets of mounting bases are provided, located at the two ends of the connecting device one and the connecting device two, respectively. The male base plate has grooves corresponding to the two mounting bases inside.

[0008] Preferably, each of the two mounting bases has two symmetrical springs installed inside, and one end of each spring is fitted with a pressure plate located inside the mounting base.

[0009] Preferably, connecting blocks are installed on both outer sides of the two pressure plates, and two symmetrical connecting grooves are opened inside the mounting base. The connecting blocks are slidably connected inside the connecting grooves, and connecting rods are installed on the top of the two pressure plates.

[0010] Preferably, a connecting frame is installed on the top of both connecting rods, and two symmetrical limiting plates are installed on the top of the connecting frame.

[0011] Preferably, a bearing is provided at the center of the connecting frame, and a connecting column is provided inside the bearing.

[0012] Preferably, a positioning plate is installed at the bottom of the connecting column, and a rotating handle is installed at the top of the connecting column.

[0013] Preferably, a limiting plate is installed on the outer side of the handle, and anti-slip grooves are distributed in a circular pattern on the outer side of the handle.

[0014] The technical effects and advantages of this invention are as follows: When using this invention, traditional snap fasteners, due to their small spacing, often cause users to excessively pull on clothing when opening them, easily resulting in fabric deformation, tearing, or wrinkles. This device, with its spacing between the male and female base plates, provides users with operating space, allowing them to place their fingers between the plates to operate the separation components without pulling on the clothing. This effectively avoids damage to the clothing fabric caused by improper operation, thereby extending the service life of the clothing and maintaining its appearance.

[0015] When the hook is in the connected state, the positioning plate in the separation component is misaligned with the positioning groove, which positions the connecting frame. At the same time, the spring is in the initial relaxed state, and the pressure plate is inserted into the limiting groove of the fixed seat. The dual mechanism effectively prevents accidental opening and improves the safety of the hook. These designs make the operation more convenient and accurate, greatly improving the user experience.

Detailed Implementation

[0023] 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.

[0024] As attached Figure 1-6 The high-stability anti-accidental opening hook shown includes a male hook seat 1, a male base plate 2, a female hook seat 3 and a female base plate 4. The bottom of the male base plate 2 is provided with a connecting device 1 5, the top of the female base plate 4 is provided with a connecting device 2 6, the male hook seat 1 is provided with a separation component 7, the top of the female base plate 4 is provided with two symmetrical fixing seats 8, the top of the male base plate 2 is provided with a positioning groove 9, and the fixing seats 8 are provided with a limit groove 10. The separating assembly 7 includes a mounting base 71 installed inside the male fastener 1. Two sets of mounting bases 71 are provided, located at the ends of connecting device 5 and connecting device 6, respectively. The male base plate 2 has grooves corresponding to the two mounting bases 71. Two symmetrical springs 72 are installed inside each of the two mounting bases 71. A pressure plate 73 is installed at one end of each of the two springs 72, located inside the mounting base 71. Connecting blocks 74 are installed on both sides of the outer surfaces of the two pressure plates 73. Two symmetrical connecting grooves 75 are formed inside the mounting base 71, and the connecting blocks 74 are slidably connected. Inside the connecting groove 75, a connecting rod 76 is installed on the top of each of the two pressure plates 73. A connecting frame 77 is installed on the top of the two connecting rods 76. Two symmetrical limiting plates 78 are installed on the top of the connecting frame 77. A bearing 79 is provided at the center of the connecting frame 77. A connecting column 710 is provided inside the bearing 79. A positioning plate 711 is installed at the bottom of the connecting column 710. A rotating handle 712 is installed at the top of the connecting column 710. A limiting plate 713 is installed on the outside of the rotating handle 712. A circularly distributed anti-slip groove 714 is provided on the outside of the rotating handle 712. A certain gap is left between the male base plate 2 and the female base plate 4. This design provides the user with operating space. When it is necessary to separate the male buckle 1 from the female buckle 3, the user can place his / her fingers in the gap, which makes it easier to operate the separation component 7 later and improves the convenience of use. The male base plate 2 has grooves corresponding to two mounting seats 71 inside, providing installation space for the mounting seats 71 and allowing them to be firmly fixed inside the male base plate 2. This enhances the connection strength between the separation component 7 and the male base plate 2, ensuring that the separation component 7 will not loosen or fall off during operation. The spring 72 plays an important elastic reset role in the separation component 7. When the hook is closed, the spring 72 is in an initially relaxed state, providing a certain support force for the pressure plate 73, allowing the pressure plate 73 to be stably inserted into the limiting groove 10, limiting the position of the male hook seat 1 and the female hook seat 3, and preventing accidental opening. When the hook needs to be opened, the pressure plate 73 drives the spring 72 to move. When the hook is closed again, the spring 72 drives the pressure plate 73 back to the initial position, so that the hook automatically returns to a stable closed state. The connecting block 74 is slidably connected in the connecting groove 75 opened inside the mounting base 71. This design ensures that the pressure plate 73 can move up and down stably without deviation or shaking. The connecting rod 76 and the connecting frame 77 play the role of transmitting force. Through the movement of the connecting frame 77, the two pressure plates 73 can be moved at the same time. While rotating the handle 712, the two limiting plates 713 installed on the outside of the handle 712 interact with each other, thereby limiting the handle 712 and allowing the positioning plate 711 to accurately correspond to the positioning groove 9, which facilitates the subsequent movement of the positioning plate 711 within the positioning groove 9.

[0025] Working principle of the present invention: Both connecting device 5 and connecting device 6 are existing structures as disclosed in CN222516312U. Connecting device 5 includes: a buckle, a countersunk hole, a central hole, an annular cover plate, a U-shaped outer edge, a strip groove, a first stepped surface, a steel ball, a spring seat, a spring, a blind hole, a first permanent magnet, and a first insertion hole. Connecting device 6 includes a housing, a slot, a U-shaped groove, a second stepped surface, a second permanent magnet, and a second insertion hole. Specific embodiments are not described in detail here. When connecting device 1 5 and connecting device 2 6 are connected, the user holds the connecting frame 77 and moves it upward so that the pressure plate 73 is located in the mounting base 71. When the pressure plate 73 corresponds to the limiting groove 10, the connecting frame 77 is released and the pressure plate 73 is located in the limiting groove 10 by the setting of the spring 72. When the hook is in the connected state, the positioning plate 711 in the separation assembly 7 is located on top of the male buckle seat 1. The positioning plate 711 is offset from the positioning groove 9, which can position the connecting frame 77 and prevent the user from accidentally touching the connecting frame 77 and opening the device. At the same time, the spring 72 is in the initial relaxed state, and the two symmetrical pressing plates 73 are inserted into the limiting grooves 10 opened inside the two symmetrical fixing seats 8, which restricts the position of the male buckle seat 1 and the female buckle seat 3, so that the entire hook is in a stable closed state and effectively prevents accidental opening. When it is necessary to separate the male buckle 1 from the female buckle 3, since there is a certain gap between the male base plate 2 and the female base plate 4, the user places his / her finger between the male base plate 2 and the female base plate 4 for easy subsequent operation. Then, the user rotates the handle 712 with one of his / her fingers. Since the handle 712 has anti-slip grooves 714 distributed in a circular shape on the outside, it increases the friction between the hand and the handle 712, making it easier for the user to apply force. The user rotates the handle 712 clockwise or counterclockwise. The rotation of the handle 712 will drive the connecting column 710 to rotate in the bearing 79 set in the center of the connecting frame 77. The function of the bearing 79 is to reduce the friction when the connecting column 710 rotates, making the rotation smoother. The rotation of the connecting column 710 will drive the positioning plate 711 installed at its bottom to rotate until the positioning plate 711 corresponds to the position of the positioning groove 9. Then, press down on the connecting frame 77. When the connecting bracket 77 moves downward, it will drive the two pressure plates 73 to move downward. When the pressure plates 73 move downward, they will stretch the two symmetrical springs 72 inside the mounting base 71. As the pressure plates 73 move downward, the positioning plate 711 slides in the positioning groove 9. When the pressure plates 73 move, the male buckle 1 and the female buckle 3 are separated by force, and the connecting device 1 5 and the connecting device 2 6 can be unlocked to complete the operation.
