Description

Technical Field

[0001] This utility model relates to the technical field of elastic strap structure, specifically to an elastic strap that can be conveniently and quickly tied to items and prevents them from easily coming loose. Background Technology

[0002] Existing elastic bandages, such as Figure 1 and Figure 2 As shown, its structure includes a strap 10 and a buckle 11 attached to the head end of the strap 10. The strap 10 has a plurality of positioning holes 12 spaced apart. The buckle 11 has a frame hole 13, and a pin 14 extends obliquely from the outer frame. The tail end of the strap 10 can be wrapped around at least one item and then passed through the frame hole 13 from bottom to top, allowing the pin 14 to be inserted into one of the positioning holes 12, thereby achieving the purpose of quickly tightening the items.

[0003] Because the pin 14 of the buckle 11 of the existing elastic strap is a smooth, pointed cone that gradually tapers from the root to the end, the pin 14 can easily slip out of the positioning hole 12 after being inserted into one of the positioning holes 12. In particular, the end of the strap 10 is not restrained after passing through the buckle 11 and is in a free and open state. Therefore, it is easy for it to be touched by external objects and swing, causing the pin 14 to slip out of the positioning hole 12. As a result, the elastic strap is prone to loosening and causing the item to fall off accidentally. Utility Model Content

[0004] The main purpose of this invention is to solve the problem that the pin of the buckle of the existing elastic strap can easily slip out of the positioning hole of the strap, thus causing the elastic strap to loosen easily.

[0005] The elastic strap of this utility model includes a strap and a buckle. The strap is an elastic band with an end and a tail, and has a plurality of spaced-apart positioning holes. The buckle is a rectangular frame with a frame hole and a front frame bar and a rear frame bar located on opposite sides of the frame hole. The front frame bar connects to the end of the strap, and a pin extends obliquely upwards and backwards from the center of the rear frame bar, with a protrusion at the end of the pin. Furthermore, the tail end of the strap can be wrapped around at least one item and then passed upwards through the frame hole, where the pin is inserted into one of the positioning holes, allowing the protrusion at the end of the pin to extend to the other side of the strap, thereby tightening the items.

[0006] The elastic strap provided by this utility model allows for convenient and quick binding and securing of items by wrapping the end of the strap around at least one item, passing it upwards through a frame hole, and then inserting a pin into a positioning hole. Specifically, the protrusion at the end of the pin extends to the other side of the strap to form a secure lock, preventing the pin from slipping out of the positioning hole and thus avoiding easy loosening of the elastic strap.

[0007] Continuing on the above, the elastic strap described in this utility model may further include a fixing buckle, which is generally flat and S-shaped, forming a lower slot and an upper slot that are open on two opposite sides, respectively for the middle section and the tail end of the strap to pass through. A lower protrusion and an upper protrusion are respectively provided at both ends to limit the openings of the lower and upper slots. In this way, the tail end of the strap can be fixed to one side of the strap by the fixing buckle, preventing the tail end of the strap from being accidentally touched and causing the pin to slip out of the positioning hole, thereby preventing the elastic strap from easily loosening.

[0051] Please see Figures 3 to 7 As shown, the elastic strap of this utility model includes a strap 20, a buckle 30, and a fixing buckle 40, wherein:

[0052] The strap 20 is an elastic strap with a head end 21 and a tail end 22, and has a plurality of positioning holes 23 arranged at intervals. The head end 21 has a large head 24, so that the cross-section of the head 24 is generally T-shaped.

[0053] The buckle 30 is a rectangular frame with a frame hole 31 and a front frame bar 32 and a rear frame bar 33 located on opposite sides of the frame hole 31. The front frame bar 32 has a through hole 34 through which the tail end 22 of the strap 20 passes, so that the head 24 of the head end 21 is engaged in the frame hole 31, thereby connecting the head end 21 of the strap 20 with the front frame bar 32. The upper side of the rear frame bar 33 forms an upward-opening notch 35, and a pin 36 extends obliquely from the center of the rear frame bar 33 at a 35-degree angle backward and upward. The lower side of the end of the pin 36 has a protrusion 37, making the end of the pin 36 hook-shaped.

[0054] The fastening buckle 40 is generally flat and S-shaped, forming a lower slot 41 and an upper slot 42 that are open on two opposite sides, allowing the middle section and the tail end 22 of the strap 20 to pass through respectively. A lower protrusion 43 and an upper protrusion 44 are respectively provided at both ends of the fastening buckle 40 to restrict the openings of the lower slot 41 and the upper slot 42, so as to prevent the strap 20 from easily slipping out of the openings.

[0055] exist Figure 8 As can be seen, the tail end 22 of the strap 20 can be wrapped around at least one item (such as a bicycle frame 50 and a water bottle 51, or other items such as an umbrella, hand tools, pump, etc.), and then passed through the frame hole 31 from bottom to top. The pin 36 is then inserted into a positioning hole 23, and the protrusion 37 at the end of the pin 36 extends to the other side of the strap 20 to lock it, thereby achieving the purpose of tightening these items (such as tightening and fixing the water bottle 51 to the bicycle frame 50). Then, the lower slot 41 of the fixing buckle 40 is fastened to the middle section of the strap 20, and the tail end 22 of the strap 20 is passed through the upper slot 42 of the fixing buckle 40, so that the tail end 22 of the strap 20 is thus constrained and fixed to one side of the strap 20, and will not swing or move freely.

[0056] The elastic strap provided by this utility model allows for convenient and quick binding and securing of items by wrapping the tail end 22 of the strap 20 around at least one item, passing it upwards through the frame hole 31, and then inserting the pin 36 into a positioning hole 23. Specifically, the protrusion 37 at the end of the pin 36 extends to the other side of the strap 20 to form a secure lock, preventing the pin 36 from slipping out of the positioning hole 23 and thus avoiding easy loosening of the elastic strap. Furthermore, the fixing buckle 40 can constrain and fix the tail end 22 of the strap 20 to one side of the strap 20, preventing the tail end 22 from swinging, swaying, or being accidentally touched, which could cause the pin 36 to slip out of the positioning hole 23, thereby preventing easy loosening of the elastic strap.

[0057] Please see Figure 9 and Figure 10 As shown, another embodiment of the fixing buckle 40 of this utility model has a structure that is generally the same as the above embodiment. The difference is that the upper side of the fixing buckle 40 in this embodiment is provided with a post 45. The end of the post 45 forms a snap-fit ​​part 46 with an outer diameter larger than the diameter of the positioning holes 23. The post 45 is provided with a shrinkage groove 47 that extends to the end and is open, so that the snap-fit ​​part 46 of the post 45 can elastically shrink its outer diameter through the shrinkage groove 47 to pass through the positioning hole 23.

[0058] Thus, when the tail end 22 of the strap 20 can be inserted into the upper slot 42 of the fixing buckle 40, the insert 45 can also be inserted into one of the positioning holes 23 on the tail end 22 of the strap 20, and the buckle part 46 can be protruding and fastened to the other side of the positioning hole 23. This achieves the same purpose of securing and fixing the tail end 22 of the strap 20 to one side of the strap 20. Figure 11 As shown.

[0059] Additionally, please see Figure 12 As shown, when the head end 21 of the strap 20 breaks off, the pin 45 of the fastener 40 can be inserted into the positioning hole 23 at the head end 21 of the strap 20, and the buckle part 46 can be protruded and fastened to the other side of the positioning hole 23. Then, the tail end 22 of the strap 20 is passed through the through hole 34 of the buckle 30, so that the fastener 40 is embedded in the frame hole 31, and the frame hole 31 still has enough space for the strap 20 to pass through, so that the fastener 40 can temporarily replace the head end 24 of the strap 20. In this way, the broken strap 20 can still be used temporarily.
