A type of elbow cable tie Technical Field
[0001] This utility model relates to the field of cable tie technology, and in particular to elbow cable ties. Background Technology
[0002] Cable ties, also known as wire ties, cable bundles, or locking straps, are a type of strap used to bundle items. Classified by material, cable ties can generally be divided into nylon cable ties, stainless steel cable ties, and powder-coated stainless steel cable ties. Classified by function, there are many types, including ordinary cable ties, retractable cable ties, label cable ties, fixed locking cable ties, pin-type cable ties, and heavy-duty cable ties, among others. Cable ties are widely used in Christmas gift factories, electronics factories, wire processing plants, wire and cable factories, toy factories, festive occasions, stationery and general merchandise stores, fresh food supermarkets, household goods, electrical appliances, connectors, and other items for bundling.
[0003] Cable ties consist of a fixedly connected strap body and a locking head. The locking head has a spring clip with locking teeth. One side of the strap body has a row of teeth integrally formed on its outer wall. In use, the strap body passes through the locking head, causing the spring clip to engage the locking teeth under its own elastic force, thus achieving the effect of preventing the strap body from slipping out of control. However, this type of cable tie currently has the following shortcomings:
[0004] If teeth are set on only one side of the belt, external force will shake the belt, causing the teeth to move away from the locking teeth and become disengaged or slip off, resulting in loose binding.
[0005] When cable ties are used to bind objects, there is a large gap between the locking head and the object at the connection point, making it easy for the item to slide off the cable tie and detach, resulting in an insecure binding. Utility Model Content
[0006] The present invention provides a curved cable tie to solve the technical problems of existing cable ties where teeth are set on one side of the strap body, and the teeth will disengage or slip off when they are far from the locking teeth, resulting in loose binding; or, when the cable tie is used to bind an object, there is a large gap between the connection between the locking head and the strap body and the object, resulting in an insecure binding.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0008] A curved cable tie includes a locking head, a curved portion, and a strap body connected in sequence. The locking head has an inlet and a pull-out end formed at both ends of its inner cavity. The end of the strap body away from the locking head can enter the inner cavity of the locking head through the inlet, so that the strap body, the curved portion, and the locking head form a fixed cavity.
[0009] The belt body has teeth on both opposite sides, and the inner cavity of the locking head has locking teeth that match the teeth. The extension direction of the curved part is inclined to the extension direction of the belt body.
[0010] In one embodiment, the locking head has a first fixing surface facing the fixing cavity, the bent portion has a second fixing surface facing the fixing cavity, and the belt has a third fixing surface facing the fixing cavity;
[0011] The second fixing surface is an arc-shaped surface, the length extension direction of the first fixing surface is tangent to the length extension direction of the second fixing surface, and / or the length extension direction of the third fixing surface is tangent to the length extension direction of the second fixing surface.
[0012] In one embodiment, the outer wall of the locking head is a square platform structure, and the locking head also has a first side surface connected to the first fixing surface. The first side surface is located on the side of the locking head away from the curved portion, and the insertion port is located at the connection between the first fixing surface and the first side surface.
[0013] In one embodiment, the locking head further has a second side disposed opposite to the first side, and the pull-out outlet is located on the second side.
[0014] In one embodiment, the teeth are internal teeth, and grooves are provided on both sides of the belt body in the thickness direction. Each groove is provided with a plurality of internal teeth, and the internal teeth are adapted to the locking teeth. The internal teeth on both sides of the belt body in the thickness direction have an asymmetrical structure.
[0015] In one embodiment, the end of the groove near the locking head forms a bending groove, which extends sequentially from the end of the belt near the bending portion to the bending portion and the locking head.
[0016] In one embodiment, the side of the inner tooth away from the locking head forms an inclined inner guide surface, the side of the inner tooth close to the locking head forms an inner stop surface, an inner platform is formed on the side of the inner tooth away from the belt body, and an inner flat groove is formed on the outer wall of the belt body between two adjacent inner teeth.
[0017] In one embodiment, the locking tooth includes a fixed tooth and an elastic block, the fixed tooth and the elastic block are respectively located on the sidewalls of opposite sides of the inner cavity of the locking head, and the fixed tooth and the elastic block respectively engage with the belt teeth on opposite sides of the belt body.
[0018] In one embodiment, the end of the belt away from the locking head is formed with a protruding head, the thickness of which is less than the thickness of the belt.
[0019] In one embodiment, the end of the protruding head away from the locking head is formed with a triangular guide portion, the width of which increases from the end away from the locking head to the end closer to the locking head.
[0020] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:
[0021] In this embodiment of the utility model, the curved cable tie has teeth on both outer walls of the strap body, which, in conjunction with locking teeth on both inner walls of the locking head, allows the strap body to be inserted from the inlet and pulled out from the outlet during binding. This allows the strap body to pass through the locking head and bind the item. At this time, the teeth on both sides of the strap body engage with the locking teeth, achieving the purpose of preventing the strap body from slipping. The teeth on both sides ensure that the overall thickness of the strap body is uniform, preventing the strap body from breaking when it is bent during binding. At the same time, the force on both sides is reduced, preventing the individual teeth from breaking. The engagement on both sides prevents the teeth from loosening when the strap body is pulled, resulting in a more stable binding.
[0022] In addition, a curved part is provided between the locking head and the strap body. The extension direction of the curved part is inclined to the extension direction of the strap body. So when binding, the curved part can be close to the outer surface of the item and reduce the gap between the curved cable tie and the item, which can prevent the item from sliding out of the fixing cavity and making the binding more stable.

[0040] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.
[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0043] Referring to Figures 1 to 8, this embodiment of the utility model provides a bent cable tie, which is used for bundling items.
[0044] First, please refer to Figures 1 to 4. The elbow cable tie includes a locking head 1, a bending part 6, and a strap body 2 connected in sequence. The two ends of the inner cavity of the locking head 1 form a pull-out outlet 11 as shown in Figure 2 and an insertion inlet 12 as shown in Figure 4, respectively. The end of the strap body 2 away from the locking head 1 can enter the inner cavity of the locking head 1 through the insertion inlet 12, so that the strap body 2, the bending part 6, and the locking head 1 enclose and form a fixing cavity 7 for fixing the object.
[0045] Both sides of the belt body 2 are provided with belt teeth 3, and the inner cavity of the locking head 1 is provided with locking teeth 4 that are adapted to the belt teeth 3. The extension direction of the curved part 6 is inclined to the extension direction of the belt body 2.
[0046] In this embodiment of the utility model, the curved cable tie has teeth 3 on both outer walls of the strap body 2, which, together with locking teeth 4 on both inner walls of the locking head 1, allow the strap body 2 to extend into the inlet 12 and be pulled out from the outlet 11 during binding. This allows the strap body 2 to pass through the locking head 1 to bind the item. At this time, the teeth 3 on both sides of the strap body 2 engage with the locking teeth 4, achieving the purpose of preventing the strap body 2 from retracting. The teeth 3 on both sides ensure that the overall thickness of the strap body 2 is uniform, preventing the strap body 2 from breaking when it is bent during binding. At the same time, the force on both sides is reduced, preventing the individual teeth from breaking. The engagement on both sides prevents the teeth from loosening when the strap body 2 is pulled, making the binding more stable.
[0047] In addition, a curved part 6 is provided between the locking head 1 and the strap body 2. The extension direction of the curved part 6 is inclined to the extension direction of the strap body 2. So when binding, the curved part 6 can be close to the outer surface of the item and reduce the gap between the curved cable tie and the item, which can prevent the item from sliding out of the fixing cavity 7 and making the binding more stable.
[0048] Referring to Figure 3, specifically, the end of the belt body 2 away from the locking head 1 is formed with an extension head 5. The thickness of the extension head 5 is less than the thickness of the belt body 2, so that the extension head 5 extends into the inlet 12 and drives the belt body 2 into the inner cavity of the locking head 1.
[0049] Furthermore, a triangular guide portion 52 is formed at the end of the protruding 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 closer to the locking head 1. In this way, the width of the lower end of the guide portion 52 is smaller, so that the guide portion 52 can be aligned with the insertion port 12, making it easier for the user to insert the guide portion 52 into the insertion port 12.
[0050] Specifically, referring to Figures 5 to 8, Figure 7 illustrates 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 body 2 has a third fixing surface 21 facing the fixing cavity 7. The second fixing surface 61 is an arc-shaped 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 is smoother, reducing bending, or the transition area between the second fixing surface 61 and the third fixing surface 21 is smoother, reducing bending, so that the first fixing surface 13, the second fixing surface 61, and the third fixing surface 21 can fit tightly against the outer surface of the item, preventing the item from sliding out of the fixing cavity 7 and making the binding more secure.
[0051] Specifically, the outer wall of the locking head 1 is a square platform structure, and the locking head 1 also has a first side surface 14 connected to the first fixing surface 13. The first side surface 14 is located on the side of the locking head 1 away from the curved part 6, and the insertion port 12 is located at the connection point of the first side surface 14 of the first fixing surface 13. In this way, the insertion port 12 is closer to the first fixing surface 13, and when binding items, the strap 2 on the side of the insertion port 12 is closer to the items, which can prevent the items from sliding out of the fixing cavity 7 and making the binding more stable.
[0052] Furthermore, the locking head 1 also has a second side 15 opposite to the first side 14, with the pull-out port 11 located on the second side 15, and the inner cavity of the locking head 1 extending in a straight line. This makes the angle between the length extension direction of the inner cavity of the locking head 1 and the first fixing surface 13 smaller, so that when binding items, the strap 2 on the side extending into the port 12 is closer to the item, preventing the item from sliding out of the fixing cavity 7 and making the binding more stable.
[0053] Referring to Figures 6 and 8, in this embodiment of the invention, the teeth 3 are internal teeth 33. Grooves 32 are provided on both opposite sides of the belt body 2 along its thickness direction. Each groove 32 has multiple internal teeth 33, which are adapted to the locking teeth 4. The internal teeth 33 on both sides of the belt body 2 along its thickness direction have an asymmetrical structure, with the internal teeth 33 on both sides staggered along the length of the belt body 2. The tooth surfaces of the teeth 3 on both sides at the same cross-section partially overlap along the thickness direction of the belt body 2. Setting the teeth 3 as internal teeth 33 avoids the teeth 3 protruding from the outer surface of the belt body 2 and causing discomfort to the hand, thus affecting the user experience. The staggered arrangement of the internal teeth 33 on both sides of the belt body 2 along its length direction prevents the teeth 3 on both sides from simultaneously disengaging from the locking teeth 4 inside the locking head 1 under force, resulting in a more secure binding.
[0054] It is understood that in other embodiments, if the teeth 3 protrude from the outer surface of the belt body 2 and are not considered to be sharp, the teeth 3 can also be set as convex teeth. In this case, the teeth 3 on both sides of the belt body 2 are convex teeth, or the teeth 3 on both sides of the belt body 2 are internal teeth 33 and convex teeth respectively, which is still within the protection scope of this utility model.
[0055] Referring to Figures 4 and 6, specifically, a bending groove 34 is formed at the end of the groove 32 near the locking head 1. The bending groove 34 extends sequentially from the end of the strap body 2 near the bending portion 6 to the bending portion 6 and then to the locking head 1. The bending groove 34 does not have teeth 3 and reduces the thickness of the bent cable tie at the corresponding position of the bending groove 34, making it easier for the bent cable tie to bend inward through the bending groove 34 and thus pass through the locking head 1.
[0056] Furthermore, referring to Figure 8, the side of the internal tooth 33 away from the locking head 1 forms an inclined inner guide surface 331, and the side of the internal tooth 33 near the locking head 1 forms an inner stop surface 332. An inner flat groove 334 is formed on the outer wall of the belt body 2 between two adjacent internal teeth 33. In this way, the meshing between the internal tooth 33 and the locking tooth 4 is more stable, and the locking head 1 has a better anti-reverse effect on the belt body 2.
[0057] Specifically, referring to Figures 6 and 7, the locking tooth 4 includes a fixed tooth 41 and an elastic block 42. The fixed tooth 41 is fixedly provided on the inner wall of the locking head 1 away from the belt body 2. One end of the elastic block 42 is fixedly connected to the inner wall of the locking head 1 near the belt body 2. Multiple movable teeth 43 are fixedly provided on the side of the elastic block 42 near the fixed tooth 41. The fixed tooth 41 and the movable teeth 43 are respectively meshed with the inner teeth 33 on both sides of the thickness direction of the belt body 2. The width of the elastic block 42 is equal to the width of the groove 32. The end of the elastic block 42 near the insertion port 12 is fixedly connected to the inner wall of the locking head 1. The fixed tooth 41 is near the inner wall of the locking head 1 at the pull-out port 11.
[0058] Thus, by setting fixed teeth 41 and movable teeth 43, the belt body 2 achieves the purpose of meshing force on both sides. The force on both sides reduces the force on individual teeth, avoiding tooth breakage. The meshing on both sides prevents teeth from loosening when the belt body 2 is pulled, thus improving the binding strength. In addition, due to the presence of 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 movable teeth 43 with inner teeth 33. Under the action of external force, the belt body 2 can slide within the inner cavity of the locking head 1.
[0059] Referring again to 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 strap body 2, so that the formed strap can be more easily removed from the mold during the production process of the strap, thereby reducing production costs.
[0060] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many 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. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
