Technical Field
[0001] This application relates to the technical field of seat belt buckles, and in particular to a novel seat belt buckle. Background Technology
[0002] A safety harness is a protective device used to ensure the safety of people when working at heights, near edges, or on buildings with a risk of fall. Its main function is to prevent accidental falls or to mitigate injuries in the event of a fall. Its design typically combines the general structure of a safety harness with the specific requirements of a walkway environment. It generally consists of restraint components such as a waist belt, shoulder straps, and leg straps, as well as connecting components.
[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: the unlocking structure in the existing technology is relatively simple, and non-professionals can unlock it themselves, which may lead to accidental unlocking due to accidental touch or careless operation by the user, posing a great threat to user safety. Utility Model Content
[0004] To prevent unauthorized personnel from accidentally unlocking the buckle and causing potential hazards, this application provides a novel seatbelt buckle.
[0005] This application provides a novel seat belt buckle, which adopts the following technical solution: it includes a seat belt, a connecting strap is fixedly connected to the front of the seat belt, a first strap is fixedly connected to the bottom of the connecting strap, and a second strap is fixedly connected to the bottom of the connecting strap away from the first strap.
[0006] The seat belt has an irregularly shaped key on the front and an irregularly shaped slot on the back. The inner wall of the irregularly shaped slot is in contact with the outer wall of the anti-accidental contact plate.
[0007] Optionally, the seat belt has a fixing box on the front, the fixing box has an assembly groove on the front, an anti-accidental contact box is fixedly connected to the inner wall of the assembly groove, the anti-accidental contact box has sliding grooves at the top and bottom, and a moving block is slidably connected to the inner wall of the upper sliding groove.
[0008] Optionally, there are two movable blocks, which are symmetrically arranged. A spring telescopic column is fixedly connected to the top of the upper movable block. The top of the spring telescopic column is fixedly connected to the top of the inner wall of the fixed box. A rotating plate is rotatably connected to the back of the movable block, and a rotating groove is opened on the front of the rotating plate.
[0009] Optionally, a connecting plate is rotatably connected to the inner wall of the rotating groove. A limit hole is opened on the front of the connecting plate. A limit post is slidably connected to the inner wall of the limit hole. The front of the limit post is fixedly connected to the back of the anti-accidental contact box. A snap-fit post is fixedly connected to the back of the connecting plate. A slot is opened on the front of the snap-fit post. The inner wall of the slot contacts the outer wall of the limit post. A slot is opened on the front of the safety belt. The inner wall of the slot contacts the outer wall of the snap-fit post.
[0010] Optionally, the inner wall of the anti-accidental touch box contacts the outer wall of the irregular key, and an anti-accidental touch plate is fixedly connected to the inner wall of the anti-accidental touch box.
[0011] Optionally, the anti-accidental touch plate is adapted to the irregularly shaped card slot, and a push block is fixedly connected to the front of the irregularly shaped key.

[0013] In summary, this application includes the following beneficial technical effects:
[0014] 1. This utility model incorporates components such as an irregularly shaped key, an anti-accidental touch plate, and an irregularly shaped slot. Because the irregularly shaped key has a unique compatibility with the anti-accidental touch box and the anti-accidental touch plate, and the irregularly shaped key is kept by designated personnel, the unlocking mechanism can only be triggered when a staff member inserts the matching irregularly shaped key into the anti-accidental touch box, ensuring that the irregularly shaped slot and the anti-accidental touch plate are precisely aligned. This fundamentally prevents accidental unlocking caused by unauthorized touch or improper operation, significantly improving the security performance of the lock.
[0015] 2. This utility model, by incorporating components such as a movable block, a spring telescopic column, and a rotating plate, allows for easy adjustment of the tightness of the straps and seat belts. Simply push the irregularly shaped key to apply external force, causing the movable block to slide within the sliding groove. The extension and retraction of the spring telescopic column, along with the linkage between the rotating plate and the connecting plate, enables the quick separation or engagement of the locking column and the locking groove, thereby completing the adjustment and secure fixation of the straps. The operation is simple and efficient, solving the problems of cumbersome and unstable fixation in traditional adjustment methods. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0022] This application discloses a novel seatbelt buckle. For example... Figure 1 , Figure 4 As shown, the device includes a seat belt 1, a connecting strap 11 fixedly connected to the front of the seat belt 1, a first strap 12 fixedly connected to the bottom of the connecting strap 11, and a second strap 13 fixedly connected to the bottom of the connecting strap 11 away from the first strap 12. The first strap 12 and the second strap 13 are straps used for the thighs and can be adjusted in size.
[0023] In this embodiment, a non-circular key 3 is provided on the front of the seat belt 1, and a non-circular slot 311 is provided on the back of the non-circular key 3. The inner wall of the non-circular slot 311 contacts the outer wall of the anti-accidental touch plate 32. The anti-accidental touch plate 32 is adapted to the non-circular slot 311. The non-circular design of the anti-accidental touch plate 32 can prevent tourists from putting their hands into the unlocking device. It can only be unlocked by using the non-circular key 3 in the hand of the staff.
[0024] Please see Figure 4 As shown, the anti-accidental touch plate 32 is adapted to the irregular card slot 311, and the front of the irregular key 3 is fixedly connected to the push block 31. The push block 31 is designed to facilitate the operation of the staff.
[0025] Please see Figure 2 As shown, the seat belt 1 has a fixing box 2 on the front, the fixing box 2 has an assembly groove on the front, the assembly groove has an anti-accidental contact box 21 fixedly connected to the inner wall of the assembly groove, the anti-accidental contact box 21 has sliding grooves at the top and bottom, and the upper sliding groove has a moving block 211 slidably connected to the inner wall of the sliding groove.
[0026] Please see Figure 4 As shown, the inner wall of the anti-accidental touch box 21 is in contact with the outer wall of the irregular key 3, and an anti-accidental touch plate 32 is fixedly connected to the inner wall of the anti-accidental touch box 21.
[0027] Please see Figure 2 As shown, there are two moving blocks 211, which are symmetrically arranged. The top of the upper moving block 211 is fixedly connected to a spring telescopic column 22. The spring telescopic column 22 can reset and lock the device after adjustment. The top of the spring telescopic column 22 is fixedly connected to the top of the inner wall of the fixed box 2. A rotating plate 23 is rotatably connected to the back of the moving block 211. A rotating groove is opened on the front of the rotating plate 23.
[0028] Please see Figure 4 As shown, the anti-accidental touch box 21 is adapted to the irregular key 3, and the back of the irregular key 3 is in contact with the front of the moving block 211.
[0029] Please see Figure 3 As shown, a connecting plate 231 is rotatably connected to the inner wall of the rotating groove. A limit hole is opened on the front of the connecting plate 231, and a limit post 212 is slidably connected to the inner wall of the limit hole. The front of the limit post 212 is fixedly connected to the back of the anti-accidental contact box 21. A snap-fit post 24 is fixedly connected to the back of the connecting plate 231. A slot is opened on the front of the snap-fit post 24, and the inner wall of the slot is in contact with the outer wall of the limit post 212. A slot 241 is opened on the front of the safety belt 1. Metal is embedded inside the slot 241, and the snap-fit post 24 is also made of metal to prevent the device from being damaged by external forces. The inner wall of the slot 241 is in contact with the outer wall of the snap-fit post 24. The aforementioned fixing box 2 and its internal parts are all provided on the safety belt 1, the first strap 12, and the second strap 13.
[0030] The implementation principle of a novel seat belt buckle in this application embodiment is as follows: Since the seat belt 1, strap one 12, and strap two 13 are all equipped with a fixing box 2 and its internal parts, when it is necessary to adjust the tightness of strap one 12 or strap two 13 and the seat belt 1, by pushing the special-shaped key 3, the two moving blocks 211 inside the anti-accidental contact box 21 slide along the sliding groove. When the two moving blocks 211 slide, they will compress or stretch the spring telescopic column 22, and at the same time drive the two rotating plates 23 to rotate around the connection point. The rotating plates 23 drive the connecting plate 231 to move under the limiting action of the limiting column 212 through the rotating groove, thereby making the locking column 24 engage with the seat belt. The slot 241 on the strap can be separated or engaged to achieve quick adjustment and secure fixation of the strap. When the staff needs to unlock, the irregular key 3 is inserted into the anti-accidental touch box 21, so that the irregular slot 311 on the back of the irregular key 3 makes precise contact and cooperate with the anti-accidental touch plate 32 inside the anti-accidental touch box 21. When the irregular key 3 continues to be pushed, it will push the moving block 211 to move. Through the linkage structure in the strap adjustment, the locking post 24 is finally separated from the slot 241, and the unlocking operation is completed. Since the irregular key 3 is always kept in the hands of the staff, non-staff members will not be able to unlock it under the action of the anti-accidental touch plate 32, preventing accidental touch from causing an accident.
[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
