The teeth 11 may be continuous or may be arranged at intervals. The tooth 11 has a first face 111 and a second face 112, and the angle between the first face and the belt 1 is smaller than the angle between the second face 112 and the belt. The arrangement of the band body 1 and the tooth portion 11 is substantially the same as the band body of the band in the prior art, and will not be described here again.

The head 2 in this embodiment is fixed to the belt body 1, and the head 2 and the belt body 1 may be formed as an integral structure or may be separate and fixed by a connection structure, which is collectively referred to herein as two fixing structures. The head 2 is provided with a channel 21 through which the belt 1 passes and a cavity 22.

The locking portion 3 in this embodiment is disposed in the cavity 22 of the head 2 (when a majority of the locking portion 3 is disposed in the cavity 22, the locking portion 3 is considered to be disposed in the cavity 22), and when the belt 1 is inserted into the channel 21, the locking portion 3 can engage the tooth portion 11 to hold the belt 1 in the anti-slip state. Specifically, when the belt body 1 is inserted into the channel 21 in the forward direction, the first surface 112 of the tooth portion 11 overcomes the locking portion 3, so that the belt body 1 is smoothly inserted and tightened, and when the belt body 1 is to be pulled out from the channel 21, the locking portion 3 engages the second surface 112 of the tooth portion 11 to play a retaining role.

Specifically, the locking portion 3 includes an actuating member 31 and an elastic member 32, where the actuating member 31 includes a stop portion 311, and where the actuating member 31 has a locking position in which the stop portion 311 of the actuating member 31 at least partially enters the channel 21, and where the stop portion 311 engages the tooth portion 11 when the belt 1 enters the channel 21, and specifically where the stop portion 311 engages the second face 112 of the tooth portion 11 to prevent the belt 1 from being released, and a release position in which the stop portion 311 is separated from the tooth portion 11 when the belt 1 enters the channel 21, so that the belt 1 can freely pass through the channel 21, and the belt 1 can be released from the head 2.

The elastic member 32 in the present embodiment applies a force to the actuator 31, and the elastic member 32 holds the actuator 31 in the lock position without the action of other external force. In the holding position, the stopper 311 of the actuator 31 is pressed against the wall 221 inside the cavity 22 of the head 2 by the urging force of the elastic member 32, and the wall 221 plays a role in limiting the stopper 311.

In other embodiments, the unlocking portion 312 may be exposed to the outside through the hole 23, so as to facilitate the direct operation of the unlocking portion 312.

The unlocking portion 312 in this embodiment has a first unlocking portion 3121 and a second unlocking portion 3122, the hole 23 includes a first unlocking hole 231 and a second unlocking hole 232, the first unlocking hole 231 corresponds to the first unlocking portion 3121, the second unlocking hole 232 corresponds to the second unlocking portion 3122, and a gap 2301 is provided between the first unlocking hole 231 and the first unlocking portion 3121 when in the locked position.

The embodiment further includes an unlocking slip 4, where the unlocking slip 4 includes a first unlocking rod 41 and a second unlocking rod 42, the first unlocking rod 41 is matched with the first unlocking hole 231, the second unlocking rod 42 is matched with the second unlocking hole 232, and the length of the first unlocking rod 41 is greater than that of the second unlocking rod 42. When the unlocking bar 4 is correspondingly inserted into the corresponding hole 23, the first unlocking bar 41 is inserted into the gap 2301 between the first unlocking hole 231 and the first unlocking portion 3121, and pushes the first unlocking portion 3121 to rotate the actuating member 31 by a certain angle, at this time, a gap is formed between the second unlocking hole 232 and the second unlocking portion 3222, the second unlocking bar 42 is continuously inserted into the gap between the second unlocking hole 232 and the second unlocking portion 3222, and the second unlocking portion 3222 is continuously pushed, so that the actuating member 31 is continuously rotated by a certain angle, at this time, the actuating member 31 is switched to the releasing position, and the belt body 1 can be detached. Through the setting of unblock cutting 4, it has certain specializedly, plays the theftproof effect, and the operation of unblock cutting 4 is very simple.

The end portions of the first unlocking lever 41 and the second unlocking lever 42 in the present embodiment each have a tip portion. Thereby facilitating the unlocking operation.

The actuator 31 in the present embodiment includes a first actuator 301 and a second actuator 302, the first actuator 301 and the second actuator 302 are respectively connected to the elastic member 32, the first unlocking portion 3121 is provided on the first actuator 301, and the second unlocking portion 3122 is provided on the second actuator 302. In this embodiment, the first actuator 301 and the second actuator 302 are two separate components and are respectively and independently connected to the elastic component 32, and each of the first actuator 301 and the second actuator 302 has a stop portion 311, that is, when the first actuator 301 and the second actuator 302 are unlocked, the stop portions 311 of the first actuator 301 and the second actuator 302 need to be separated from the tooth portion 11.

The first actuating member 301 in this embodiment is provided with a push block 3011, and the push block 3011 cooperates with the second actuating member 302. Specifically, when the first actuator 301 rotates, the pushing block 3011 drives the second actuator 302 to rotate, so that the second actuator 302 is separated from the tooth 11 under the action of the first actuator 301.

The cavity 22 in the present embodiment is provided with a limiting portion 222 to limit the rotation angle of the first actuating member 301.

In this embodiment, the first actuator 301 is limited by the limiting portion 222 and can only rotate by a limited angle by dividing the actuator 31 into two separate components (the first actuator 301 and the second actuator 302), and at this time, unlocking can not be achieved by only pulling the first actuator 301, so that unlocking difficulty is increased and anti-theft performance is improved. That is, when the first actuating element 301 rotates to abut against the limiting portion 222, the pushing block 3011 does not drive the second actuating element 302 to the unlocking position.

The belt body 1 in this embodiment is provided with a first anti-theft sheet 5 inside in its length direction. The first anti-theft sheet 5 is injection molded and embedded into the belt body 1, so that the belt body 1 can be prevented from being cut or damaged by others, and the anti-theft and protection effects are achieved. The first anti-theft sheet 5 adopts a steel sheet to play a certain supporting role. In other embodiments, the first security sheet 5 may be disposed on the surface of the belt body 1 without the teeth 11.

The stop portion 311 in this embodiment forms an acute angle with the extending direction of the channel 21. So that the belt body 1 can be smoothly inserted; when the belt 1 is pulled out, the belt 1 and the stop portion 311 are obtuse, and one end of the stop portion will be propped against the tooth portion 11, so that the belt 1 cannot be pulled out smoothly.

The present embodiment further comprises a second security sheet 6, said second security sheet 6 covering at least part of said head 2. The second anti-theft tab 6 also serves the protection and anti-theft functions, preventing others from easily damaging the head 2.

Example 2.

As shown in fig. 8, the basic structure of the strapping structure in this embodiment is the same as that of embodiment 1, except for the structure of the actuator 31. The actuator 31 in the present embodiment is of an integral structure, that is, the actuator 31 is a single member, which is different from the structure of the actuator 31 in embodiment 1 (the actuator 31 in embodiment 1 includes two members of the first actuator 301 and the second actuator 302). The first unlocking portion 3121 and the second unlocking portion 3122 are both provided on the actuator 31.

The foregoing description of the utility model is merely exemplary of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions, without departing from the scope of the utility model as defined in the accompanying claims.
