[0045] Belt teeth 3 are provided on opposite sides of the belt body 2 , and the inner cavity of the locking head 1 is provided with locking teeth 4 adapted to the belt teeth 3 . The extending direction of the curved portion 6 is inclined to the extending direction of the belt body 2 .

[0046] The elbow cable tie in the embodiment of the present invention has belt teeth 3 provided on the outer walls of both sides of the belt body 2, combined with the locking teeth 4 provided on the inner walls of both sides of the locking head 1. Therefore, when bundling, the end of the belt body 2 away from the locking head 1 is inserted into the insertion port 12 and pulled out from the pull-out port 11, thereby passing the belt body 2 through the locking head 1 to bundle the articles. At this time, the belt teeth 3 on both sides of the belt body 2 are engaged with the locking teeth 4 to achieve the purpose of stopping the belt body 2 from retreating. The arrangement of the belt teeth 3 on both sides makes the overall thickness of the belt body 2 uniform, avoiding the belt body 2 from breaking when bending during bundling. At the same time, the force on both sides reduces the force on a single tooth, avoiding tooth breakage. The engagement on both sides avoids the teeth from loosening when the belt body 2 is pulled, and the bundling is more stable.

[0047] In addition, a bent portion 6 is provided between the locking head 1 and the belt body 2. The extension direction of the bent portion 6 is inclined to the extension direction of the belt body 2, so that when bundling, the bent portion 6 can be close to the outer surface of the article and reduce the gap between the elbow tie and the article, which can prevent the article from sliding out of the fixing cavity 7 and making the bundling more stable.

[0048] refer to Figure 3 Specifically, a protruding head 5 is formed at one end of the belt body 2 away from the locking head 1, and the thickness of the protruding head 5 is less than the thickness of the belt body 2, so that the protruding head 5 can be inserted into the insertion port 12 and drive the belt body 2 into the inner cavity of the locking head 1.

[0049] Further, the extending head 5 is formed with a triangular guide portion 52 at the end away from the locking head 1, the width of the guide portion 52 increases from the end away from the locking head 1 to the end close to the locking head 1. In this way, the width of the end of the guide portion 52 is smaller, so that the guide portion 52 is aligned with the extending opening 12, and the user can easily extend the guide portion 52 into the extending opening 12.

[0050] Specifically, in combination with reference to Figures 5 to 8 , Figure 7 It is shown that the locking head 1 has a first fixing surface 13 facing the fixing cavity 7, the curved portion 6 has a second fixing surface 61 facing the fixing cavity 7, and the belt 2 has a third fixing surface 21 facing the fixing cavity 7. The second fixing surface 61 is an arc surface and extends along the arc direction, the length extension direction of the first fixing surface 13 is tangent to the length extension direction of the second fixing surface 61, and / or the length extension direction of the third fixing surface 21 is tangent to the length extension direction of the second fixing surface 61. In this way, the transition area between the second fixing surface 61 and the first fixing surface 13 can be smoother, the bending is reduced, or the transition area between the second fixing surface 61 and the third fixing surface 21 is smoother, the bending is reduced, so that the first fixing surface 13, the second fixing surface 61 and the third fixing surface 21 can closely adhere to the outer surface of the article, preventing the article from sliding out of the fixing cavity 7, and the bundling is more stable.

[0051] Specifically, the outer wall of the locking head 1 is a square table structure, the locking head 1 further has a first side surface 14 connected with the first fixing surface 13, the first side surface 14 is located at the side of the locking head 1 away from the curved portion 6, and the extending opening 12 is located at the connection of the first side surface 14 of the first fixing surface 13. In this way, the extending opening 12 is closer to the first fixing surface 13, and when bundling the article, the belt 2 on the side of the extending opening 12 is closer to the article, preventing the article from sliding out of the fixing cavity 7, and the bundling is more stable.

[0052] Further, the locking head 1 further has a second side surface 15 opposite to the first side surface 14, the pulling opening 11 is located at the second side surface 15, and the inner cavity of the locking head 1 extends along a straight line. In this way, the included angle between the length extension direction of the inner cavity of the locking head 1 and the first fixing surface 13 is smaller, and when bundling the article, the belt 2 on the side of the extending opening 12 is closer to the article, preventing the article from sliding out of the fixing cavity 7, and the bundling is more stable.

The teeth 3 are arranged as the internal teeth 33, which can avoid the teeth 3 protruding from the outer surface of the band body 2 and scratching hands, and affect the use experience. Misaligning the internal teeth 33 on the two sides of the band body 2 in the length direction of the band body 2 can avoid the teeth 3 on the two sides from being separated from the locking teeth 4 in the locking head 1 at the same time under stress, and the bundling is more stable.

[0054] It can be understood that in other embodiments, without considering the case that the teeth 3 protrude from the outer surface of the band body 2 and scratch hands, the teeth 3 can also be arranged as protruding teeth, at this time, the teeth 3 on the two sides of the band body 2 are all protruding teeth, or the teeth 3 on the two sides of the band body 2 are internal teeth 33 and protruding teeth respectively, which are still within the protection scope of the utility model.

[0055] For reference Figure 4 And Figure 6 Specifically, the end of the groove 32 close to the locking head 1 forms a bending groove 34, and the bending groove 34 extends from the end of the band body 2 close to the bending part 6 to the bending part 6 and the locking head 1 in sequence. The bending groove 34 is not provided with the teeth 3 and reduces the thickness of the elbow strap at the corresponding position of the bending groove 34, so that the elbow strap can be bent inward through the bending groove 34, thereby penetrating the locking head 1.

[0056] Further, referring to Figure 8 The side of the internal tooth 33 away from the locking head 1 forms an inclined internal guide surface 331, the side of the internal tooth 33 close to the locking head 1 forms an internal stop surface 332, and the outer wall of the band body 2 between the two adjacent internal teeth 33 forms an internal flat groove 334. In this way, the engagement between the internal tooth 33 and the locking tooth 4 is more stable, and the locking head 1 has a better retreat prevention effect on the band body 2.

[0057] Specifically, referring to Figure 6 And Figure 7 The locking tooth 4 includes a fixed tooth 41 and an elastic block 42, the inner wall of the locking head 1 away from the band body 2 is fixedly provided with the fixed tooth 41, the inner wall of the locking head 1 close to the band body 2 is fixedly connected to one end of the elastic block 42, the side of the elastic block 42 close to the fixed tooth 41 is fixedly provided with a plurality of movable teeth 43, the fixed tooth 41 and the movable tooth 43 are respectively matched with the internal teeth 33 on the two sides of the band body 2 in the thickness direction, the width of the elastic block 42 is equal to the width of the groove 32, one end of the elastic block 42 close to the stretching opening 12 is fixedly connected to the inner wall of the locking head 1, and the inner wall of the locking head 1 close to the pulling opening 11 is provided with the fixed tooth 41.

[0058] Thus, by setting the fixed teeth 41 and the movable teeth 43, the purpose of engaging the force on both sides of the belt body 2 is achieved, the force on both sides is reduced, the force on a single tooth is reduced, the tooth is prevented from breaking, the engagement on both sides is avoided, the tooth is prevented from loosening when the belt body 2 is pulled, and the bundling firmness is improved. In addition, due to the setting of the elastic block 42, the user can operate the elastic block 42 to rotate relative to the side wall of the inner cavity of the locking head 1, thereby releasing the engagement of the movable teeth 43 on the inner teeth 33, and the belt body 2 can slide in the inner cavity of the locking head 1 under the action of an external force.

[0059] With reference to the above Figure 6 In this embodiment, the extension direction of the inner cavity of the locking head 1 is perpendicular or approximately perpendicular to the length extension direction of the belt body 2, so that in the production process of the cable tie, the formed cable tie is more easily separated from the mold, and the production cost is reduced.
