Description

Technical Field

[0001] This application relates to the field of seat belt technology, and more specifically, to a helmet seat belt. Background Technology

[0002] The helmet harness is an important accessory component of a helmet. It is mainly used to securely fix the helmet to the user's head, preventing the helmet from shaking or falling off during wear and affecting its protective effect. At the same time, it can flexibly adjust the tightness according to the user's head circumference, taking into account both stability and comfort. In scenarios such as cycling and sports, it assists the helmet in playing a safety protection role and ensures the safety of the user's head.

[0003] In practice, helmet seat belts are not convenient enough for one-handed operation of fixing and unlocking. It is difficult to quickly align and achieve a stable limit when fixing, requiring two hands. Unlocking also requires complicated operations, and loosening is easy after fixing, which affects the stability of the helmet and makes it inconvenient for users to quickly put on and take off the helmet with one hand. Utility Model Content

[0004] The purpose of this application is to provide a helmet safety belt that solves the technical problems mentioned in the background art.

[0005] This application provides a helmet safety belt, including a first strap and a second strap. One end of the first strap is wrapped with a wrapping loop, and one end of the wrapping loop is fixedly connected to a connecting strip. A fixing component is provided between the connecting strip and the second strap.

[0006] The fixing component includes a first ring and a second ring that are fixedly connected to one end of the connecting strip and the second strap, respectively. A fixing sleeve is fixedly connected to the outer wall of the second ring. A pair of slots are symmetrically opened on the outer wall of the fixing sleeve. A fixing strip is fixedly connected to the outer wall of the first ring. A fixing block is fixedly connected to both ends of one side of the fixing strip. A fixing rod is provided at one end of the fixing block.

[0007] Optionally, a positioning cylinder is fixedly connected inside the fixing sleeve, and an insertion rod is fixedly connected at the center of one side of the fixing strip, with an extension sleeve slidably sleeved at one end of the insertion rod.

[0008] Optionally, a spring is internally fixed between the insertion rod and the extension sleeve, and the extension sleeve is located inside the positioning cylinder.

[0009] Optionally, each of the two fixed rods has a locking block fixedly connected to its opposite end face. The end face of the locking block near the second ring has an embedding groove, and the locking block is located in the groove.

[0010] Optionally, a clamping groove is provided on the end face of the fixing rod near the fixing block, the fixing block is located inside the clamping groove, and an installation rod is fixedly connected inside the clamping groove, with the installation rod penetrating through the fixing block.

[0011] Optionally, a torsion spring is sleeved around the mounting rod, one end of which is fixedly connected to the mounting rod, and the other end of which is fixedly connected to the fixing block.

[0012] Optionally, a chin rest is slidably fitted around the periphery of the first strap.

[0013] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0014] This application allows for easy one-handed hooking of the first and second finger rings and bringing them close together, aligning the insertion rod and extension sleeve with the positioning cylinder. During the pushing process, the extension sleeve retracts, the spring compresses, and the locking block of the fixing rod is squeezed and rotates. Once the locking block reaches the slot, the torsion spring and spring return to their original positions, causing the locking block to engage with the slot and fit tightly against the inner wall of the slot, effectively limiting the locking block and preventing loosening. Tightening the wrapping ring further tightens the strap, ensuring a secure helmet fit and preventing it from falling off during use. For disassembly, pressing the locking blocks on both sides with one hand disengages them from the slot, causing the spring and torsion spring to return to their original positions, separating the first and second finger rings, quickly unlocking the fixing components, and facilitating the removal of the strap with one hand. This eliminates the need for complicated operations, greatly improving the practicality of the device and making it convenient for one-handed use. Attached Figure Description

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-3 This application provides a helmet safety belt, including a first strap 1 and a second strap 3. One end of the first strap 1 is wrapped with a wrapping ring 4, and one end of the wrapping ring 4 is fixedly connected to a connecting strip 5. A fixing component 6 is provided between the connecting strip 5 and the second strap 3. The wrapping ring 4 is wrapped with the first strap 1, and the tightness of the first strap 1 and the second strap 3 can be adjusted.

[0021] The fixing component 6 includes a first ring 601 and a second ring 602, which are respectively fixedly connected to one end of the connecting strip 5 and the second strap 3. A fixing sleeve 603 is fixedly connected to the outer wall of the second ring 602. A pair of slots 605 are symmetrically formed on the outer wall of the fixing sleeve 603. A fixing strip 606 is fixedly connected to the outer wall of the first ring 601. Fixing blocks 610 are fixedly connected to both ends of one side of the fixing strip 606. A fixing rod 611 is provided at one end of each fixing block 610. Locking blocks 612 are fixedly connected to the opposite ends of the two fixing rods 611. An embedding groove 613 is formed on the end face of the locking block 612 near the second ring 602. The locking block 612 is located within the slot 605. A clamping groove 616 is provided on the end face of 611 near the fixing block 610. The fixing block 610 is located inside the clamping groove 616. An installation rod 614 is fixedly connected inside the clamping groove 616 and passes through the fixing block 610. A torsion spring 615 is sleeved around the installation rod 614. One end of the torsion spring 615 is fixedly connected to the installation rod 614 and the other end of the torsion spring 615 is fixedly connected to the fixing block 610. The locking block 612 of the fixing rod 611 is squeezed and rotates. When the locking block 612 reaches the locking groove 605, the torsion spring 615 returns to its original position, so that the locking block 612 is locked into the locking groove 605 and embedded in the groove 613, which fits tightly against the inner wall of the locking groove 605, effectively limiting the locking block 612 to prevent loosening.

[0022] The fixing sleeve 603 is internally fixedly connected to a positioning cylinder 604. A rod 607 is fixedly connected to the center of one side of the fixing strip 606. One end of the rod 607 is slidably sleeved with an extension sleeve 608. A spring 609 is internally fixedly connected between the rod 607 and the extension sleeve 608. The extension sleeve 608 is located inside the positioning cylinder 604. The rod 607 and the extension sleeve 608 enter the positioning cylinder 604, which plays a good positioning role. At the same time, when disassembling, pressing the two side locking blocks 612 with one hand can make them disengage from the locking slot 605. The spring 609 rebounds to its original state, so that the rod 607, the extension sleeve 608 and the positioning cylinder 604 can be quickly separated, and the fixing component 6 can be quickly unlocked.

[0023] The chin support 2 is slidably attached to the outer periphery of the first strap 1. The first strap 1 and the second strap 3 are fixed to the sides of the helmet. The chin support 2 can be adjusted to fit under the chin, which can improve the fit and comfort when wearing it and avoid discomfort in the chin area.

[0024] Working principle: First, fix the first strap 1 and the second strap 3 to both sides of the helmet. Adjust the position of the chin rest 2 around the first strap 1 so that it fits under the chin. Hook the first ring 601 and the second ring 602 with two fingers of one hand respectively, and move the first ring 601 closer to the second ring 602, so that the insert 607 and the extension sleeve 608 on one side of the fixing strip 606 are aligned with the positioning cylinder 604 inside the fixing sleeve 603. Continue to push the first ring 601, and the extension sleeve 608 enters the positioning cylinder 604 and is squeezed. The extension sleeve 608 retracts into the insert 607, and the spring 609 is compressed. Simultaneously, the fixing rods 611 on the fixing blocks 610 on both sides of the fixing strip 606 move with the first ring 601. The locking block 612 at one end of the fixing rod 611 contacts the inner wall of the fixing sleeve 603. After being squeezed, the locking block 612 rotates around the mounting rod 614, and the torsion spring 615 deforms. The inner wall of the clamping groove 616 rotates relative to the fixing block 610. When the locking block 612 moves to the clamping groove 605 of the fixing sleeve 603, the torsion spring 615 returns to its original position, causing the fixing rod 611 to rotate in the opposite direction. The locking block 612 is then inserted into the clamping groove 605, and the embedding groove 613 fits against the inner wall of the clamping groove 605. At the same time, the spring 609 returns to its original position, so that the embedding groove 613 on the locking block 612 fits tightly against the inner wall of the clamping groove 605, thereby limiting the locking block 612 and preventing it from loosening. Finally, one end of the first binding strap 1 connected to the winding ring 4 is tightened, making the first binding strap 1 and the second binding strap 3 taut. When disassembly is required, press the locking blocks 612 on both sides inward with your fingers simultaneously. The inclined surface of the embedded groove 613 slides against the inner wall of the groove 605, and the locking block 612 rotates around the mounting rod 614. The torsion spring 615 deforms, and the locking block 612 disengages from the groove 605. The spring 609 rebounds, and the insertion rod 607 and extension sleeve 608 pop out from the positioning cylinder 604. At the same time, the fixing rod 611 pops out from the fixing sleeve 603, and the torsion spring 615, fixing rod 611, and spring 609 return to their natural state. The first ring 601 separates from the second ring 602, the fixing component 6 is unlocked, and the first strap 1 and the second strap 3 can be removed from the head with one hand, completing the seat belt disassembly.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
