Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] refer to Figures 1 to 13 An embodiment of the present invention provides a cable tie, which is used for bundling items.

[0049] Combined with reference Figures 1 to 6 The cable tie includes a locking head 1 and a belt body 2 connected to each other, an insertion port 12 and a pull-out port 11 are respectively formed at both ends of the inner cavity of the locking head 1, the belt body 2 is provided with belt teeth 3, and the inner cavity of the locking head 1 is provided with locking teeth 4 adapted to the belt teeth 3. One end of the belt body 2 can be inserted into the insertion port 12, so that the locking head 1 and the belt body 2 enclose a fixed cavity 7 for fixing objects.

[0050] Combined with reference Figure 1 and Figure 5 , Figure 5 It is illustrated that the belt tooth 3 has a small end 35 and a large end 36 in the width direction, and the width of the belt tooth 3 increases gradually from the small end 35 toward the large end 36 in the length direction of the belt body 2 .

[0051] In the cable tie of the embodiment of the present invention, when the belt body 2 enters the inner cavity of the locking head 1 from the insertion opening 12 along its length direction, the small end 35 and the large end 36 of the belt teeth 3 successively enter and engage with the locking teeth 4. Since the width of the belt teeth 3 increases from the small end 35 toward the large end 36, the gradually increasing width plays a guiding role, making the belt body 2 enter the locking head 1 more smoothly, and the user saves effort when pulling the belt body 2.

[0052] In addition, the belt teeth 3 extend roughly along the length direction of the belt body 2 . The belt teeth 3 are similar to reinforcing ribs, which play a protective role when the belt body 2 is subjected to external forces in the cross-sectional direction, and can effectively prevent the cross-sectional fracture of the belt body 2 .

[0053] Continue to refer Figure 5Specifically, the belt teeth 3 are V-shaped teeth 37, which include a first tooth 371 and a second tooth 372 connected to each other, the first tooth 371 and the second tooth 372 are arranged at an angle, the small end 35 is the connection between the first tooth 371 and the second tooth 372, and the large end 36 is the other end of the V-shaped tooth 37 away from the small end 35. In this way, the first tooth 371 and the second tooth 372 both extend in a straight line direction, so that the belt body 2 is pulled into the locking head 1 more smoothly.

[0054] It is understood that in other embodiments, the belt teeth 3 can be set to other shapes, for example, the belt teeth 3 are set to semicircular teeth, and the semicircular teeth are composed of two arc-shaped teeth. As long as the technical solution that can achieve the guide by increasing the width of the belt teeth 3 in the length direction of the belt body 2 should be within the protection scope of the present invention.

[0055] Furthermore, the first teeth 371 and the second teeth 372 are symmetrically arranged with respect to the length direction of the belt body 2. In this way, when the user drives the belt body 2, the forces on both sides of the V-shaped teeth 37 are evenly applied, and the pulling is smoother.

[0056] Specifically, the V-shaped teeth 37 are inner teeth 33, the outer surface of the belt body 2 is provided with a groove 32, the groove 32 is provided with a plurality of inner teeth 33, the inner teeth 33 away from the locking head 1 form an inclined inner guide surface 331, the inner teeth 33 close to the locking head 1 form an inner stop surface 332, and the outer wall of the belt body 2 between two adjacent inner teeth 33 forms an inner flat groove 334. By providing the inner guide surface 331, the resistance when the user pulls the belt body 2 can be reduced, and the smoothness of pulling can be further improved.

[0057] refer to Figure 6 Specifically, the locking tooth 4 is an elastic block 42, and a plurality of movable teeth 43 are provided on one side surface of the elastic block 42, and the movable teeth 43 are adapted to the V-shaped teeth 37. Due to the provision 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 with the V-shaped teeth 37, and the belt body 2 can slide in the inner cavity of the locking head 1 under the action of external force, thereby detaching the belt body 2 from the locking head 1.

[0058] Specifically, the V-shaped teeth 37 are located on the side surface of the belt body 2 facing the fixing cavity 7, and the elastic block 42 is located on the side wall of the inner cavity of the locking head 1 close to the belt body 2. In this way, when the cable tie is used to tie an object, the V-shaped teeth 37 contact the object, increasing the friction between the belt body 2 and the object, making the cable tie more stable.

[0059] Combined with reference Figure 7 , Figure 8 and Fig. 9 In another embodiment, Fig. 9The diagram shows that the V-shaped teeth 37 are located on the side surface of the belt body 2 away from the fixing cavity 7, and the elastic block 42 is located on the side wall of the inner cavity of the locking head 1 away from the belt body 2. In this way, when the cable tie is used to tie objects, the V-shaped teeth 37 are exposed on the belt body 2, and the surface of the belt body 2 close to the object does not have the V-shaped teeth 37, which can prevent the V-shaped teeth from leaving marks on the object, so that the surface of the object remains intact.

[0060] Combined with reference Figures 10 to 13 , in one embodiment, Fig.13 It is shown that V-shaped teeth 37 are provided on opposite sides of the belt body 2 , and the V-shaped teeth 37 on both sides of the belt body 2 are matched with the locking teeth 4 , and the V-shaped teeth 37 in the thickness direction of the belt body 2 are an asymmetric structure.

[0061] Since the belt teeth 3 are arranged on both sides of the belt body 2, combined with the locking teeth 4 arranged on the inner wall of the locking head 1, when bundling, the end of the belt body 2 away from the locking head 1 is inserted from the insertion port 12 and pulled out from the pulling port 11, so that the belt body 2 passes 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 meshed 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 breakage of the belt body 2 when it is bent during bundling. At the same time, the force on both sides reduces the force on a single tooth, avoiding tooth breakage. The meshing on both sides avoids the loosening of the teeth caused by the pulling of the belt body 2, and the bundling is more stable.

[0062] Continue to refer Fig.13 The V-shaped teeth 37 in the thickness direction of the belt body 2 are set to an asymmetric structure, and the V-shaped teeth 37 on both sides of the thickness direction of the belt body 2 are staggered in the length direction of the belt body 2, which can prevent the V-shaped teeth 37 on both sides from simultaneously disengaging from the locking teeth 4 in the locking head 1 when subjected to force, making the bundling more stable.

[0063] refer to Figure 8 and Fig.12 Specifically, the V-shaped teeth 37 are internal teeth 33, and grooves 32 are provided on opposite sides of the belt body 2 in the thickness direction. Each groove 32 is provided with multiple internal teeth 33, and a bending groove 34 is formed at one end of the groove 32 close to the locking head 1. The bending groove 34 extends from the end of the belt body 2 close to the locking head 1 to the locking head 1.

[0064] It can be understood that in other embodiments, without considering that the V-shaped teeth 37 protrude from the outer surface of the belt body 2 and are irritating, the V-shaped teeth 37 can also be set as convex teeth. In this case, the V-shaped teeth 37 on both sides of the belt body 2 are convex teeth, or the V-shaped teeth 37 on both sides of the belt body 2 are inner teeth 33 and convex teeth respectively, which is still within the protection scope of the present invention.

[0065] The bending groove 34 is not provided with the belt teeth 3 and the thickness of the elbow tie at the position corresponding to the bending groove 34 is reduced, so that the elbow tie is convenient to bend inward through the bending groove 34 and thus pass through the locking head 1 .

[0066] Combined with reference Figures 11 to 13 In this embodiment, the cable tie also includes a bending portion 6, and the two ends of the bending portion 6 in the length direction are respectively connected to the locking head 1 and the belt body 2, and the bending groove 34 extends from the end of the belt body 2 close to the bending portion 6 to the bending portion 6 and the locking head 1 in sequence.

[0067] A bending portion 6 is provided between the locking head 1 and the belt body 2, and the extension direction of the bending portion 6 is inclined to the extension direction of the belt body 2, so that when bundling, the bending 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.

[0068] Continue to refer Fig.13 Specifically, 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 body 2 has a third fixing surface 21 facing the fixing cavity 7. The second fixing surface 61 is an arcuate surface and extends along the arcuate 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 6161.

[0069] In this way, the transition area between the second fixing surface 61 and the first fixing surface 13 can be made smoother and reduce bending, or the transition area between the second fixing surface 61 and the third fixing surface 21 can be made smoother and reduce bending, so that the first fixing surface 13, the second fixing surface 61 and the third fixing surface 21 can be tightly attached to the outer surface of the article, which can prevent the article from sliding out of the fixing cavity 7 and bundling more stably.

[0070] Specifically, in the present embodiment, the locking teeth 4 include fixed teeth 41 and elastic blocks 42. The fixed teeth 41 are fixedly provided on the inner wall of the locking head 1 away from the belt body 2. The inner wall of the locking head 1 close to the belt body 2 is fixedly connected to one end of the elastic block 42. A plurality of movable teeth 43 are fixedly provided on a side of the elastic block 42 close to the fixed teeth 41. The fixed teeth 41 and the movable teeth 43 are respectively meshed with the V-shaped teeth 37 on both sides of the belt body 2 in the thickness direction. The width of the elastic block 42 is equal to the width of the groove 32. The end of the elastic block 42 close to the insertion port 12 is fixedly connected to the inner wall of the locking head 1. The fixed teeth 41 are close to the inner wall of the locking head 1 at the pull-out port 11.

[0071] In this way, by providing the fixed teeth 41 and the movable teeth 43, the purpose of meshing and bearing force on both sides of the belt body 2 is achieved. The force on both sides reduces the force on a single tooth, avoiding tooth breakage, and the meshing on both sides prevents the teeth from loosening when the belt body 2 is pulled, thereby improving the binding strength. In addition, since the elastic block 42 is provided, 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 meshing of the movable teeth 43 with the V-shaped teeth 37, and the belt body 2 can slide in the inner cavity of the locking head 1 under the action of external force.

[0072] Combined with reference Figure 1 , Figure 4 , Figure 7 and Fig.10 In some embodiments, 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 extend into the insertion port 12 and drive the belt body 2 into the inner cavity of the locking head 1.

[0073] Furthermore, a triangular guide portion 52 is formed at one end of the extension head 5 away from the locking head 1, and 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 guide portion 52 at the front end is smaller, so that the guide portion 52 is aligned with the insertion opening 12, and the user can insert the guide portion 52 into the insertion opening 12.

[0074] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
