Description

Technical Field

[0001] The invention relates to the technical field of binding, and in particular to an anti-pulling cable tie. Background Art

[0002] Cable ties are a convenient and practical item used to tie and fix items. Cable ties have the characteristics of fast tying, good insulation, self-locking and fastening, and easy use. They can be used in electronics factories to tie up internal connecting wires of TVs, computers, etc., to fix the internal circuits of products such as lighting, motors, and electronic toys, to fix the oil pipelines of mechanical equipment, to fix the cable lines on ships, to pack bicycles or to tie up other objects, and can also be used to tie up items in agriculture, gardening, handicrafts, etc.

[0003] The cable ties that are widely used are mainly plastic cable ties, and most of them are self-locking structure cable ties. After being tied, they are not allowed to loosen and can only be tied tighter and tighter. However, for many products that are tied, they are difficult to distinguish after integrated tying, so they need to be marked separately; at the same time, the existing cable ties usually only include a fixed head and a beveled tooth cassette, and the self-locking is achieved by clamping the teeth at the fixed head with the beveled tooth cassette, but the beveled tooth cassette often fails to self-lock when it is pulled in the opposite direction. The cable ties currently on the market can basically be pulled out of the locking spring from the back or front with other tools (such as needles or slender parts), and the belt body can be pulled out, which does not play an anti-counterfeiting role.

[0004] Therefore, there are areas for improvement in the existing cable tie structure, and it is necessary to improve and optimize it to obtain a more reasonable technical solution and solve the deficiencies in the existing technology. Summary of the invention

[0005] In order to overcome the defects of the prior art mentioned in the above content, the present invention provides an anti-pullout cable tie, which aims to improve the structure of the head and the belt body of the cable tie so that the binding effect of the cable tie is more ideal. After the belt body and the head are clamped and fixed, the belt body will not fail to self-lock when subjected to forces in other directions.

[0006] In order to achieve the above object, the technical solution specifically adopted by the present invention is:

[0007] An anti-pulling cable tie comprises a head and a belt body, wherein the front end of the belt body is connected to the head, the head is provided with a locking hole, the inner wall of the locking hole is provided with a locking spring sheet, and an anti-pulling boss is provided on the inner wall of the locking hole opposite to the locking spring sheet; the belt body is provided with a guide groove which slides with the locking spring sheet, and a plurality of locking holes are provided in the guide groove.

[0008] The cable tie disclosed above is locked by passing the strap body through the locking hole and snapping the locking spring into the locking hole. At the same time, the anti-pullout boss presses the strap body toward the locking hole to prevent the locking hole and the locking spring from failing to cooperate when the strap body is subjected to forces in other directions.

[0009] Furthermore, the locking spring is in contact and clamped with the locking hole. When in contact, the structure of the locking contact surface directly affects the locking effect. The structure of the locking spring is optimized here, and the following feasible solutions are given: the locking contact surface of the locking spring is an outwardly convex straight surface, a V-shaped surface or a C-shaped surface.

[0010] Furthermore, the structure of the locking hole is also optimized corresponding to the structure of the locking spring sheet. Specifically, the locking contact surface between the locking hole and the locking spring sheet is a corresponding straight-line surface, a V-shaped surface or a C-shaped surface. When configured in this way, the locking spring sheet and the locking hole are not only in contact with a plane, but the straight-line surface, the V-shaped surface or the C-shaped surface can increase the contact area and enhance the locking effect.

[0011] Furthermore, the arrangement of the locking spring in the lock hole is not uniquely determined. Here, the structure of the locking spring is optimized and the following specific feasible methods are given. The locking spring is arranged obliquely on the inner wall of the lock hole. When cooperating with the belt body, the locking spring passes through the locking hole and prevents the belt body from retreating. The locking contact surface of the locking hole is an inclined surface.

[0012] Furthermore, after using cable ties to tie products, it is necessary to annotate information about the products. An optimized setting is performed here, and the following specific feasible solutions are given: the head is provided with a marking portion, and the marking portion is provided with marking information.

[0013] Furthermore, the marking part is integrally formed with the head, and an information code can be set on the marking part by laser engraving, printing, printing, or mold forming. The information code data carrier can be a QR code or RFID, and a sticker with handwritten information can also be set for remarks.

[0014] Furthermore, the marking part disclosed in the above technical solution can protect the information after the information is annotated. Specifically, the following feasible solutions are given: the anti-pulling cable tie also includes a protective member, which cooperates with the marking part and is used to cover the marking part. The protective member is used to protect the information code from being scratched or tampered. If the information code does not need to be protected, the protective member can be omitted; the protective member can be formed of a transparent material; the protective member can be formed on the cable tie body by two-color injection molding, or assembled on the cable tie body by a snap-on method.

[0015] Furthermore, in order to facilitate the binding operation, the structure of the belt body is optimized, and the following specific feasible solution is given: a traction structure is provided at the end of the belt body, and the traction structure includes a gradually narrowing traction section provided at the end of the belt body.

[0016] Furthermore, the traction section is integrally formed with the belt body, and the width of the traction section gradually narrows, which helps to pass through the lock hole, thereby driving the belt body to pass through the lock hole; the front part of the traction section is also arranged in an arc shape, which can help it to pass through the lock hole better.

[0017] Furthermore, when performing the binding operation, the hand of the same structure pinches the traction section to perform the pulling operation. The traction section is the force-bearing part. In order to improve the firmness of the binding, the structure of the traction section is further optimized, and an anti-slip strip is provided on the traction section.

[0018] Furthermore, the structure of the traction section is further optimized, and anti-slip holes are provided on the traction section.

[0019] Furthermore, the connection between the belt body and the head is also a stress-bearing part, and the structure of the connection is strengthened here. Specifically, the following feasible solution is given: the connection between the head and the belt body is provided with reinforcing ribs.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention improves the matching structure of the locking spring sheet at the head and the locking hole of the belt body, increases the contact area, strengthens the locking meshing force, and at the same time provides a tightening boss to help connect the locking spring sheet and the locking hole, greatly enhancing the locking effect. Since the locking spring sheet and the tightening boss are provided to cooperate, the locking spring sheet cannot be pushed away from the front and back of the belt body to cause the locking of the belt body to fail. Therefore, once locked, it can be prevented from being reopened, which can play an anti-counterfeiting role. BRIEF DESCRIPTION OF THE DRAWINGS

The specific structures and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0032] Example

[0033] In view of the fact that the existing cable tie structure is not sufficient to provide a stable and reliable binding effect, this embodiment optimizes and improves the structure of the cable tie to provide a stable binding effect without causing self-locking failure due to external forces.

[0034] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, this embodiment discloses an anti-pulling cable tie, including a head 1 and a belt body 4, the front end of the belt body 4 is connected to the head 1, the head 1 is provided with a locking hole 2, the inner wall of the locking hole 2 is provided with a locking spring 3, and an anti-pulling boss 12 is provided on the inner wall of the locking hole 2 opposite to the locking spring 3; the belt body 4 is provided with a guide groove 5 that slides with the locking spring 3, and a plurality of locking holes 6 are provided in the guide groove 5.

[0035] like Figure 4 , Figure 5 As shown, the cable tie disclosed above is locked by passing the belt body 4 through the locking hole 2 and the locking spring piece 3 is inserted into the locking hole 6. At the same time, the anti-pullout boss 12 squeezes the belt body 4 toward the locking hole 6 to prevent the locking hole 6 and the locking spring piece 3 from failing to cooperate when the belt body 4 is subjected to forces in other directions.

[0036] The head 1 and the belt body 4 are integrally formed and made of polyurethane material.

[0037] like Figure 6As shown, the locking spring 3 is in contact and clamped with the locking hole 6. When in contact, the structure of the locking contact surface directly affects the locking effect. The structure of the locking spring is optimized here, and the following feasible solutions are given: the locking contact surface of the locking spring 3 is an outwardly convex straight surface, a V-shaped surface or a C-shaped surface.

[0038] Corresponding to the structure of the locking spring piece 3, the structure of the locking hole 6 is also optimized, specifically: the locking contact surface between the locking hole 6 and the locking spring piece 3 is a corresponding straight surface, a V-shaped surface or a C-shaped surface. When configured in this way, the locking spring piece 3 and the locking hole 6 are not only in contact with a plane, but the straight surface, the V-shaped surface or the C-shaped surface can increase the contact area and enhance the locking effect.

[0039] Preferably, the locking contact surfaces in this embodiment are all V-shaped surfaces.
