Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

The first embodiment is as follows: referring to fig. 1, the embodiment is specifically described, and the power cable bundling belt in the embodiment includes a plurality of locking heads and a belt body with a length of at least 50cm, wherein the locking heads and the belt body are separated from each other, and are not an integral structure in the prior art. The belt body is of a ratchet structure. The lock head is provided with a through channel 1, and at least one pawl 2 which can be meshed with the ratchet 9 on the belt body is arranged in the channel 1.

As shown in fig. 7 and 8, a plurality of clamping grooves 8 are arranged on one side of the belt body, which is far away from the ratchet teeth 9, along the length direction of the belt body, and the direction of the groove depth of each clamping groove 8 is the same as the direction of the ratchet teeth 9, namely, the groove depth of each clamping groove inclines towards one end and forms an acute angle with the length direction. The section of the clamping groove 8 along the length direction of the belt body is triangular, and the bottom of the clamping groove is pointed.

As shown in fig. 3 and 4, the lock head is provided with a key 3 on the outer side wall facing away from the pawl 2, and the key 3 extends in the direction opposite to the direction of the pawl 2.

In practical application, the key 3 of the power cable bundling strap according to the embodiment can be inserted into the slot 8 at one end of the strap body, and the two are mutually bonded to realize connection. The strap is then passed around the bundled cable and the other end of the strap is inserted into the channel 1 so that the pawl 2 in the channel engages the ratchet 9 on the strap. Due to the structure of the ratchet bar and the pawl, the belt body can only move towards the outlet direction of the channel and cannot reversely exit, so that the bound cables are tighter and tighter, and the binding purpose is finally realized. After the binding is completed, the remaining strip is cut at the outlet of the channel 1.

After the operations, as shown in fig. 1, at one side of the key 3, the key 3 and the slot 8 are locked with each other, and the lock head is pulled by the belt body towards the arrow direction at the left side of fig. 1. In the channel, because the extending direction of the key 3 is opposite to the direction of the pawl 2, under the engagement of the ratchet 9 and the pawl 2, the belt body pulls the lock head in the arrow direction on the right side of the figure 1. That is, after the cable is locked, the lock head cannot move due to opposite pulling forces, and the cable is bound.

And the rest of the band body after being cut off can also be matched with another lock head to form a group of new strapping band structures to bind other cables. Because the length of the belt body is not limited any more, the method has stronger adaptability and flexibility to the thickness of the bundled cable, and waste caused by overlong belt body is avoided. Meanwhile, because the existing strapping tapes are all made of plastics, a large amount of waste of the plastic tape body can bring white pollution. This embodiment very big reduction the waste of the area body, reduced subsequent white pollution volume.

Furthermore, the arrangement of the clamping groove 8 in the embodiment can be used for being connected with the key 3 on the lock head, the material consumption of the belt body can be reduced, and the manufacturing cost is reduced.

Further, the structure of the lock head middle key 3 can be designed into two types in the using process:

first, as shown in fig. 2 and 3, the key 3 is an oblique protruding structure integrated with the lock, so that the key is formed integrally and has a simple structure.

Secondly, as shown in fig. 4 and 5, the key 3 is a single part with a cross section of a cone-shaped structure, a key groove is formed in the side wall of the lock head where the key 3 is located, and one end of the key 3 is hinged to the inner wall of the key groove through a hinge shaft 5, so that the key 3 can extend out of or retract into the key groove in a swinging manner. The key 3 is provided with a limit rod 6. The stopper rod 6 is provided along the radial direction of the hinge shaft 5. A limiting groove 7 is arranged in the key groove, the cross section of the limiting groove 7 is fan-shaped, the vertex angle of the fan-shaped is an acute angle, and the fan-shaped is concentric with the hinge shaft 5. The limiting rod 6 is located in the limiting groove 7, so that the groove walls where the two fan-shaped edges are located can limit the swing amplitude of the limiting rod 6, and further limit the angle of the key 3 to the limit. The edge of the key groove is provided with a notch 4, and the notch 4 is communicated with the key groove.

When the key 3 with the second structure is not used, the external space of the lock head is not occupied, and the manufacturing amount can be reduced. The free end of the key 3 is extracted out of the keyway by the notch 4 in use. Meanwhile, due to the limitation of the limiting rod 6 and the limiting groove 7 on the swing amplitude, the extending direction of the key 3 is opposite to the direction of the pawl 2 when the key swings to the maximum amplitude, and the locking function of the lock head is guaranteed.

The structure of the belt body also includes two types:

first, as shown in fig. 7 and 10, the card slot 8 is closed on both sides. The width of draw-in groove 8 equals with the width of key 3, and key 3 can not move to both sides after inserting draw-in groove 8, and the structure is more stable, is fit for binding of cable under the strong environment of external disturbance, if outdoor binding of walking the line.

Second, as shown in fig. 8 and 11, both sides of the card slot 8 penetrate. The width of the clamping groove 8 is consistent with that of the belt body. After the key 3 is inserted into the clamping groove 8, once the lock head or the belt body is required to be unbound, the lock head or the belt body can be pushed towards the width direction of the belt body, and the belt body and the lock head can be unbound, so that the bound cable is unbound. The structure not only reduces the preparation materials, but also can flexibly unbind. Simultaneously, the area body and the tapered end after unbundling can also reuse, reduce extravagantly.

In actual production, the distance between two adjacent clamping grooves 8 is set to be 1 cm. The closer the clamping grooves 8 are, the more materials can be used, and after the belt body is cut at any position, waste caused by the fact that the clamping grooves 8 are far away from the end part is avoided.

The overall length of the belt body is at least 50 cm. The cable is suitable for more cables needing thick wires.
