Description

Technical Field

[0001] This utility model belongs to the field of seat belt buckle technology, and specifically relates to a high-strength automotive seat belt buckle. Background Technology

[0002] The seatbelt buckle is a key component of the car seatbelt system, typically constructed from metal and engineering plastics, resulting in a robust and durable structure. Its intricate internal design includes a locking mechanism and heat-resistant, reinforcing layers, automatically locking upon impact to prevent occupants from being thrown forward. Furthermore, it must meet stringent standards for high-temperature resistance and impact resistance to ensure reliable operation even under extreme conditions. In daily use, the buckle requires regular inspection and maintenance to ensure effective protection of occupants in emergencies.

[0003] Chinese patent publication number "CN219339402U" discloses an anti-slip seat belt buckle. It includes: a seat belt buckle for engaging and securing with a seat belt clip; and an anti-slip sleeve for securing the seat belt buckle. The anti-slip sleeve has openings at both ends, and the seat belt buckle is housed within the anti-slip sleeve. This design provides an anti-slip seat belt buckle, and the anti-slip sleeve ensures the buckle's strength.

[0004] However, the above structure still has some shortcomings. Since the seat belt buckle is a consumable, its installation point will inevitably loosen after long-term use. Because the installation method of the previous seat belt buckle structure is not easy to disassemble, it will reduce the efficiency of subsequent disassembly of the seat belt buckle, and also reduce the efficiency of subsequent maintenance of the seat belt buckle. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a high-strength automotive seat belt buckle to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A high-strength car seat belt buckle includes a buckle body, a buckle groove at the top of the buckle body, a switch block at the top of the buckle body, a reinforcing plate threaded onto the outer wall of the buckle body, a connecting strap fixedly connected to the bottom of the buckle body, a connecting plate fixedly connected to the bottom of the connecting strap, a mounting plate snapped onto the bottom of the connecting plate, a positioning hole at the top of the mounting plate located on the four sides near the corners of the top of the mounting plate, a first slot at the top of the connecting plate extending into the interior of the mounting plate, a second slot on the inner wall of the first slot, a circular groove at the bottom inner side of the first slot, a first locking block snapped onto the inner side of the first slot, and a second locking block, matching the second slot, fixedly connected to the outer side of the first locking block, the second locking block snapping onto the inner side of the circular groove.

[0008] As a preferred technical solution, a retaining spring matching the second retaining block is installed at the bottom inner side of the circular groove. The bottom end of the second retaining block is engaged with the top end of the retaining spring. The second retaining block is engaged with the inner side of the circular groove through the retaining spring. A sealing block is fixedly connected to the top end of the first retaining block. The sealing block covers the top end of the first retaining groove. A protrusion is fixedly connected to the top end of the sealing block. The shape of the protrusion's corner is arc-shaped.

[0009] As a preferred technical solution, the top of the mounting plate is provided with a positioning groove, and the bottom of the connecting plate is fixedly connected with a positioning block that matches the positioning groove. The positioning block is fixedly connected to the four sides near the corner of the bottom of the connecting plate, and the positioning block is engaged with the inside of the positioning groove.

[0010] As a preferred technical solution, a rubber pad is fixedly connected to the top of the mounting plate. The rubber pad is one centimeter thick and is located on the inner side of the positioning block. The top of the rubber pad is in contact with the bottom of the connecting plate.

[0011] As a preferred technical solution, the front side of the reinforcing plate is threaded with a bolt, the locking body is located on the inner side close to the bolt, and the reinforcing plate is threadedly connected to the outer side of the locking body by the bolt.

[0012] As a preferred technical solution, the inside of the locking body is provided with a reinforcing layer, the thickness of which is one centimeter, and the reinforcing layer is made of alloy steel.

[0013] As a preferred technical solution, the inside of the locking body is provided with a heat-resistant layer, the thickness of the heat-resistant layer is five millimeters, and the heat-resistant layer is made of stainless steel.

[0014] In summary, the present invention has the following main advantages:

[0015] Firstly, during use, the mounting plate is fixed by using a positioning piece that matches the positioning hole. Then, the second locking block is sent into the circular groove by the first locking block. The second locking block is adjusted to an angle that is not corresponding to the second locking groove, so that the connection plate points can be effectively locked to limit the locking body. When the locking body needs to be disassembled and maintained later, the second locking block is adjusted to an angle corresponding to the second locking groove, and then the first locking block can be pulled out directly. This not only makes it convenient to disassemble and install the locking body, but also makes it easier for users to maintain the locking body later.

[0016] Secondly, due to the presence of the positioning block, the insertion of the positioning block can predetermine the position of the connecting plate, which not only improves the stability of the connecting plate installation but also effectively improves the accuracy of the first locking block insertion. Due to the presence of the rubber pad, the rubber pad has good anti-slip ability and rubber elasticity. When the connecting plate is locked, the connecting plate will be pressed down. After the second locking block is locked, the rebound of the rubber pad can make the second locking block lock more tightly, thereby effectively improving the stability of the connecting plate locking point.

[0025] refer to Figures 1 to 6 This embodiment of a high-strength car seatbelt buckle includes a buckle body 1, a buckle groove 2 at the top of the buckle body 1, a switch block 3 at the top of the buckle body 1, a reinforcing plate 4 threadedly connected to the outer wall of the buckle body 1, a connecting strap 6 fixedly connected to the bottom of the buckle body 1, a connecting plate 7 fixedly connected to the bottom of the connecting strap 6, a mounting plate 8 snapped onto the bottom of the connecting plate 7, and positioning holes 13 formed at the top of the mounting plate 8 near the four corners of the top of the mounting plate 8. A first slot 9 is provided at the top of the mounting plate 7, extending into the interior of the mounting plate 8. A second slot 10 is provided on the inner wall of the first slot 9, and a circular groove 11 is provided at the bottom inner side of the first slot 9. A first locking block 17 is engaged with the inner side of the first slot 9, and a second locking block 18, matching the second slot 10, is fixedly connected to the outer side of the first locking block 17. The second locking block 18 is engaged with the inner side of the circular groove 11. The car seat belt buckle mainly consists of a lock body, a locking tongue, a locking mechanism, and a button. The lock body is the main frame, the locking tongue is connected to the seat belt webbing, the locking mechanism is responsible for locking the locking tongue under specific conditions, and the button is used for unlocking. When in use, the locking tongue is inserted into the lock body, and the locking mechanism automatically locks the locking tongue, preventing it from coming out, thereby securing the seat belt. When the vehicle brakes suddenly or collides, the seat belt is subjected to force, and the locking mechanism will further tighten to prevent the locking tongue from loosening. Pressing the button can release the lock, pull out the locking tongue, and release the seat belt.

[0026] refer to Figures 1 to 5 A retaining spring 12 matching the second retaining block 18 is installed at the bottom inner side of the circular groove 11. The bottom end of the second retaining block 18 is engaged with the top end of the retaining spring 12. The second retaining block 18 is engaged with the inner side of the circular groove 11 through the retaining spring 12. A sealing block 19 is fixedly connected to the top end of the first retaining block 17. The sealing block 19 covers the top end of the first retaining groove 9. A protrusion 20 is fixedly connected to the top end of the sealing block 19. The protrusion 20 has an arc-shaped corner. Due to the presence of the retaining spring 12, the engagement of the retaining spring 12 can effectively limit the position of the second retaining block 18, thereby further improving the stability of the engagement of the second retaining block 18 and also effectively improving the stability of the engagement of the connecting plate 7.

[0027] refer to Figures 1 to 5The mounting plate 8 has a positioning groove 15 at its top. A positioning block 16 matching the positioning groove 15 is fixedly connected to the bottom of the connecting plate 7. The positioning block 16 is fixedly connected to the four sides near the corners of the bottom of the connecting plate 7. The positioning block 16 is snapped into the inside of the positioning groove 15. A rubber pad 14 with a thickness of one centimeter is fixedly connected to the top of the mounting plate 8. The rubber pad 14 is located on the inner side close to the positioning block 16, and its top is in contact with the bottom of the connecting plate 7. Due to the presence of the positioning block 16, the positioning block 16... The insertion of the connecting plate 7 can pre-define the position of the connecting plate 7, which not only improves the installation stability of the connecting plate 7, but also effectively improves the accuracy of the insertion of the first locking block 17. Due to the presence of the rubber pad 14, the rubber pad 14 has good anti-slip ability and rubber elasticity. When the connecting plate 7 is locked, the connecting plate 7 will be pressed down. After the second locking block 18 is locked, the rebound of the rubber pad 14 can make the second locking block 18 lock more tightly, thereby effectively improving the stability of the locking of the connecting plate 7.

[0028] refer to Figure 1 The front side of the reinforcing plate 4 is threaded with a bolt 5. The locking body 1 is located on the inner side close to the bolt 5. The reinforcing plate 4 is threadedly connected to the outer side of the locking body 1 by the bolt 5. Due to the presence of the bolt 5, the bolt 5 can be screwed in to effectively fix the reinforcing plate 4 to prevent the reinforcing plate 4 from falling off. The reinforcing plate 4 can effectively protect the outer side of the locking body 1, thereby improving the stability of the locking body 1. The reinforcing plate 4 can also be directly removed by unscrewing the bolt 5, so as not to hinder the user's subsequent maintenance of the locking body 1.

[0029] refer to Figure 6 The interior of the latch body 1 is provided with a reinforcing layer 21. The thickness of the reinforcing layer 21 is one centimeter. The reinforcing layer 21 is made of alloy steel. Due to the presence of the reinforcing layer 21, the alloy steel material has high tensile strength and good toughness, and can withstand greater impact force, which can effectively improve the overall strength of the latch body 1, thereby improving its service life.

[0030] refer to Figure 6 The interior of the locking body 1 is provided with a heat-resistant layer 22, which is five millimeters thick and made of stainless steel. Due to the presence of the heat-resistant layer 22, the stainless steel material has high strength, corrosion resistance and good heat resistance, and can maintain structural stability in high-temperature environments, thereby effectively improving the safety of the locking body 1.

[0031] Operating principle and advantages: In use, the mounting plate at point 8 is first fixed using a positioning component that matches the positioning hole 13. Then, the second locking block 18 is inserted into the circular groove 11 via the first locking block 17. The second locking block 18 is adjusted to a non-corresponding angle with the second slot 10, thereby effectively engaging the connecting plate at point 7 to limit the locking body 1. When the locking body 1 needs to be disassembled and maintained later, the second locking block 18 is adjusted to a corresponding angle with the second slot 10, and then the first locking block 17 is directly pulled out. The design facilitates the disassembly and assembly of the latch body 1, and also makes it easier for users to maintain the latch body 1 later. Due to the presence of the retaining spring 12, its engagement effectively limits the position of the second latch block 18, thereby further improving the stability of the engagement at the second latch block 18. It also effectively improves the stability of the engagement at the connecting plate 7. Due to the presence of the positioning block 16, its engagement pre-limits the position of the connecting plate 7, improving the installation stability of the connecting plate 7 and also effectively improving the accuracy of the engagement at the first latch block 17. Due to the presence of rubber pad 14, which provides excellent anti-slip capability and elasticity, the connecting plate 7 is pressed downwards when it engages with the second locking block 18. After the second locking block 18 engages, the rebound of rubber pad 14 ensures a tighter engagement, effectively improving the stability of the connection point engagement of the connecting plate 7. The presence of bolt 5 effectively secures the reinforcing plate 4, preventing it from falling off. The reinforcing plate 4 effectively protects the outer side of the locking body 1, thereby improving the stability of the lock. The stability of the latch body 1 is ensured by unscrewing the bolts 5, allowing the reinforcing plate 4 to be removed directly without hindering the user's subsequent maintenance of the latch body 1. Due to the presence of the reinforcing layer 21, the alloy steel material has high tensile strength and good toughness, and can withstand greater impact, effectively improving the overall strength of the latch body 1 and thus extending its service life. Due to the presence of the heat-resistant layer 22, the stainless steel material has high strength, corrosion resistance, and good heat resistance, and can maintain structural stability in high-temperature environments, thereby effectively improving the safety of the latch body 1.
