[0001] The utility model relates to the technical field of lock buckles, in particular to a multifunctional safety elastic buckle for handbags and backpacks. Background Art

[0002] Handbags and backpacks are items that people often carry when traveling, making it convenient for people to carry items. The flaps of handbags and backpacks on the market are generally equipped with buckles to secure the flaps and prevent the bag opening from opening automatically. Existing buckles basically have elastic buckles on both sides of the plug board. When the plug board is inserted into the socket, the elastic buckles on both sides will buckle into the buckle grooves on both sides of the socket, thereby achieving the plug-in connection between the plug board and the socket. To disconnect the plug board and the socket, you need to press the elastic buckles on both sides firmly to pull the plug board out of the socket. After long-term use, the elastic buckles and the inner wall of the socket will show significant wear and deformation, causing the plug board and the socket to become loose after insertion, posing a greater risk of disengagement.

DETAILED DESCRIPTION

[0019] To make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments.

[0020] Based on the described embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present disclosure.

[0021] refer to Figure 1-8 .

[0022] The utility model provides a multifunctional elastic buckle for a safety handbag and backpack, comprising a socket 1 and an inserting plate 2. The top of the socket 1 is provided with a slot 10 matching the inserting plate 2. The bottom of the slot 10 is raised to form an isosceles trapezoidal positioning platform 11. Both side surfaces of the positioning platform 11 are extended with a limited eaves 12. The top of the positioning platform 11 is provided with a limited column 13. The bottom of the inserting plate 2 is provided with an engaging groove 20 matching the positioning platform 11. The wall surface of the engaging groove 20 is provided with a limiting groove 21 corresponding to the limiting eaves 12. A through groove 22 is provided on one side of the inserting plate 2. A positioning groove 220 matching the shape of the limiting column 13 is provided at one end of the through groove 22. A first accommodating groove 23 is provided on the top of the inserting plate 2. A first magnet 3 is provided in the first accommodating groove 23. A second accommodating groove 14 is provided at the bottom of the socket 1. A second magnet 4 is provided in the second accommodating groove 14. The first magnet 3 and the second magnet 4 have opposite poles.

[0023] Its working principle is to fix the socket 1 and the plugboard 2 on one end of the two straps of the backpack respectively. When the plugboard 2 needs to be plugged into the socket 1, the engaging groove 20 at the bottom of the plugboard 2 is engaged with the positioning platform 11, and the limiting column 13 is inserted into the through groove 22. Then, the plugboard 2 is pulled back along the slot 10 until the positioning groove 220 is stuck on the limiting column 13, which plays a horizontal limiting role for the plugboard 2. The limiting eaves 12 on both sides are stuck in the limiting grooves 21 on both sides, which plays a longitudinal limiting role for the plugboard 2. The first magnet 3 and the second magnet 4 are attracted together to prevent the plugboard 2 from moving on the socket 1 and prevent the plugboard 2 from loosening from the socket 1. When the plugboard 2 needs to be removed from the socket 1, the plugboard 2 is pushed forward along the socket 1 to disengage the retaining flange 12 from the retaining groove 21. The retaining post 13 then enters the through groove 22 from the positioning groove 220. The first magnet 3 and the second magnet 4 separate, and the plugboard 2 can be removed from the socket 1. Its simple structure makes insertion and removal easy and labor-saving, reduces wear on the plugboard and the socket, and ensures a long service life and good fastening stability.

[0024] Based on the above embodiment, the top of the positioning platform 11 is provided with a first guide groove 15 arranged along the direction of the slot 10, and the top wall of the interlocking groove 20 is provided with a first guide portion 24 that matches the first guide groove 15. One end of the positioning platform 11 is provided with a first limiting slope 110, and one end of the interlocking groove 20 is provided with a second limiting slope 200 that matches the first limiting slope 110. When the plugboard 2 needs to be plugged into the socket 1, the interlocking groove 20 at the bottom of the plugboard 2 is engaged with the positioning platform 11, and then the plugboard 2 is pulled back along the slot 10. The first guide portion 24 will move along the first guide groove 15 to play a guiding role until the second limiting slope 200 abuts against the first limiting slope 110. At this time, the limiting eaves 12 on both sides will be locked into the limiting grooves 21 on both sides, and the first magnet 3 and the second magnet 4 will be attracted together, completing the plugging operation of the plugboard 2 and the socket 1.

[0025] Based on the above embodiment, two second guide portions 25 are arranged side by side on the top wall of the interlocking slot 20, and a second guide groove 16 is provided on the top of the positioning platform 11, corresponding to the second guide portions 25. When the plugboard 2 is pushed forward and backward along the slot 10, the second guide portions 25 will move along the second guide groove 16, providing guidance.

[0026] Based on the above embodiment, a first guiding bevel 120 is provided on the top edge of the limiting eaves 12, and a second guiding bevel 201 corresponding to the first guiding bevel 120 is provided on the edge of the engaging groove 20. When the plug-in board 2 needs to be plugged into the socket 1, the engaging groove 20 at the bottom of the plug-in board 2 is engaged with the positioning platform 11. Due to the adsorption effect of the first magnet 3 and the second magnet 4, when the second guiding bevel 201 contacts the first guiding bevel 120, the second guiding bevel 201 will slide along the first guiding bevel 120, and the engaging groove 20 will automatically engage with the positioning platform 11, playing a guiding role, making the engagement operation easier and more efficient.

[0027] Based on the above embodiment, a first strap groove 17 is provided on one side of the socket 1, and a second strap groove 26 is provided on one side of the plug board 2. One strap of the backpack is fixed through the second strap groove 26, and the other strap of the backpack is passed through the slot 10 and the first strap groove 17 in sequence to achieve length adjustment.

[0028] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
