Description

Technical Field

[0001] This utility model relates to the field of binding strap technology, and in particular to a self-locking binding strap. Background Technology

[0002] In many fields such as logistics and transportation, equipment securing, medical care and daily life, strapping is a tool used to fasten and bind items. Its application scenarios are extremely wide, and it is of great significance to ensure the stability of items during handling and storage and to meet the fixing needs in specific scenarios.

[0003] Currently, there are many types of binding straps on the market, but they still have many problems that need to be solved in actual use. First, in terms of locking and unlocking operations, traditional binding straps mostly use buckle, bolt, or simple knot structures. Buckle structures often have insufficient locking force and are prone to loosening under vibration or external force, making it difficult to guarantee the reliability of the fixed items; bolt structures, although locking more securely, require additional tools for installation and removal, making the operation cumbersome, time-consuming, and labor-intensive, especially in situations requiring frequent disassembly or in emergencies, greatly reducing their practicality; knot structures are not only complex to operate and require a certain level of skill from the operator, but also have difficulty in precisely controlling the degree of locking, resulting in a higher risk of loosening, and the knots are prone to wear after repeated use, affecting their service life.

[0004] Secondly, regarding the adjustment of strap tightness, existing straps offer relatively simple adjustment methods, mostly relying on manually pulling the strap or adjusting the position of simple buckles to change the tightness. This method cannot achieve precise control over the tightness; either over-adjustment results in the strap being too tight, potentially damaging the surface of the secured item, especially for soft or delicate items, easily causing unnecessary damage; or under-adjustment results in the strap being too loose, failing to provide effective fixation. Furthermore, some straps with some adjustment function lack a reliable positioning mechanism after adjustment, making them prone to displacement under external force, causing changes in tightness and further reducing the fixation effect.

[0033] The strap adjustment body 7 has two opening and closing latches 8 slidably connected on the side near the latch body 6. The opening and closing latches 8 are two L-shaped latches set opposite to each other. A return spring 11 is fixedly connected between the two opening and closing latches 8.

[0034] The locking body 6 is provided with a slot 12 that is compatible with the opening and closing locking buckle 8 on the side near the strap adjustment body 7;

[0035] The slot 12 is an inverted "T" shape, and the two ends of the horizontal slot extend into the locking body 6;

[0036] The transverse groove of the card slot 12 is slidably connected to two pressing blocks 9. Each pressing block 9 is provided with an elastic component 10. The two ends of the elastic component 10 are respectively fixedly connected to the inner wall of the card slot 12 and the pressing block 9.

[0037] When the strap 1 needs to be locked, first press the two opening and closing latches 8 to move them relative to each other, so that they are inserted into the inside of the slot 12. At this time, under the action of the return spring 11, the opening and closing latches 8 are reset and then locked into the transverse groove of the slot 12, thus completing the fixation of both ends of the strap 1. When it is necessary to remove, simply press the pressing block 9. The pressing block 9 is forced to move inward, thus pushing the opening and closing latches 8 out of the transverse groove of the slot 12. At this time, the strap adjustment body 7 and the latch body 6 can be easily separated.

[0051] Working principle: When the strap 1 needs to be locked, first press the two opening and closing latches 8 to make them move relative to each other, so that they are inserted into the inside of the slot 12. At this time, under the action of the return spring 11, the opening and closing latches 8 are reset and then locked into the transverse groove of the slot 12, thus completing the fixation of both ends of the strap 1. When it is necessary to remove, simply press the pressing block 9. The pressing block 9 moves inward under force, thus pushing the opening and closing latches 8 out of the transverse groove of the slot 12. At this time, the strap adjustment body 7 and the latch body 6 can be easily separated.

[0052] The elastic component 10 enables the pressing block 9 to automatically reset, thus preparing it for the next operation.

[0053] After the tightness of the strap 1 is adjusted, simply rotate the bolt 16. The rotation of the bolt 16 causes it to enter the hole 15, thus fixing the rotating shaft 13 and preventing the strap 1 from moving randomly after adjustment.
