[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] Please also read Figures 1 to 3 The split brake recovery customs lock 100 provided in the embodiment of the present application is now described. The split brake recovery customs lock 100 comprises: a first lock body 10, a second lock body 20 and a tightening belt 30.

[0034] The first lock body 10 includes a first winding assembly 11 , a lock plug 12 , a first movable locking tongue 13 and a first ejector pin 14 . The first winding assembly 11 includes a first winding core 111 and a first ratchet 112 . The first movable locking tongue 13 is close to the first ratchet 112 .

[0035] The second lock body 20 includes a second winding assembly 21, a locking mechanism 22, a second movable locking tongue 23 and a second ejector pin 24. The second winding assembly 21 includes a second winding core 211 and a second ratchet 212. The second movable locking tongue 23 is close to the second ratchet 212. The lock plug 12 is arranged opposite to the locking mechanism 22. The second movable locking tongue 23 is arranged opposite to the first ejector pin 14. The first movable locking tongue 13 is arranged opposite to the second ejector pin 24.

[0036] Two ends of the tightening belt 30 are respectively rolled up on the first winding core 111 and the second winding core 211 .

[0037] When the locking plug 12 is inserted into the locking mechanism 22 , the first ejector pin 14 pushes the second movable locking tongue 23 to restrict the second ratchet 212 from rotating in one direction, and the second ejector pin 24 pushes the first movable locking tongue 13 to restrict the first ratchet 112 from rotating in one direction.

[0038] It can be understood that the first lock body 10 and the second lock body 20 of the separate braking recovery customs lock 100 are only connected by the tightening belt 30 in the separated state. The tightening belt 30 can be stored on the first winding component 11 and the second winding component 21 at the same time to increase the length of the tightening belt 30. In this way, the separate braking recovery customs lock 100 can be used to tighten larger volumes of goods.

[0039] Before tightening the goods, the tightening belt 30 needs to be pre-stretched by the external force of the robot. The tightening belt 30 can be stretched by stretching the first lock body 10 and the second lock body 20 in a direction away from each other. During the stretching process of the tightening belt 30, both ends of the first winding component 11 and the second winding component 21 release the tightening belt 30 at the same time to increase the release speed of the tightening belt 30. At the same time, during the high-speed stretching process of the tightening belt 30, even if the lock body at one end is stuck, the lock body at the other end can continue to smoothly release the tightening belt 30 to avoid irreversible deformation of the winding core.

[0040] After the pre-stretching tightening belt 30 is completed, after wrapping around the cargo once, the first lock body 10 and the second lock body 20 are docked. When the lock plug 12 is inserted into the locking mechanism 22, the first ejector pin 14 pushes the second movable lock tongue 23 to limit the unidirectional rotation of the second ratchet 212, and the second ejector pin 24 pushes the first movable lock tongue 13 to limit the unidirectional rotation of the first ratchet 112.

[0041] In this way, both ends of the tightening belt 30 cannot be stretched further, and will be automatically tightened under the internal force of the first winding core 111 and the second winding core 211, so that the excess tightening belt 30 shrinks until the goods are completely tightened.

[0042] Even before the locking mechanism 22 locks the lock plug 12, the tensioning belt 30 can be limited from being stretched. In this way, before the separate brake recovery customs lock 100 receives the locking signal, the tensioning belt 30 can overcome the external force exerted by friction, rolling, inertia, etc. during the transportation of goods on the conveyor belt, maintain the tightening force, and prevent dislocation.

[0043] The goods continue to be transported on the conveyor belt. After the separated brake recovery customs lock 100 does not receive the locking signal, the locking mechanism 22 only needs to provide power to limit and fix the lock plug 12, and does not need to provide power to limit the first winding component 11 and the second winding component 21. In this way, the energy consumption and power requirements of the locking mechanism 22 during the locking and unlocking process can be reduced, the endurance of the separated brake recovery customs lock 100 can be improved, and the structure can be simplified. In addition, the locking mechanism 22 and the winding component are independently arranged. In the case of expansion of the volume of the goods, increasing the tension of the tightening belt 30 will not limit the locking and unlocking actions of the locking mechanism 22, thereby ensuring the normal operation of the locking mechanism 22.

[0044] After the locking action of the separate brake recovery customs lock 100 is completed, the goods are bound to the separate brake recovery customs lock 100. Combined with the positioning function of the separate brake recovery customs lock 100, the tracking and positioning of the goods is realized. In addition, based on the one-way brake recovery function of the separate brake recovery customs lock 100, the goods can be prevented from being maliciously disassembled during transportation, thereby improving the safety of cargo transportation.

[0045] Compared with the prior art, the separate braking recovery customs lock 100 provided in the present application can automatically perform unidirectional braking on the winding assembly after the first lock body 10 and the second lock body 20 are combined, so that the tightening belt 30 can overcome the influence of external force, maintain the tightening force, and prevent dislocation; the locking mechanism 22 and the winding assembly are arranged independently of each other, which reduces the energy consumption and power requirements of the locking mechanism 22 during the locking and unlocking process and improves smoothness; by adopting a separate structure, the storage capacity of the tightening belt 30 is improved, and the stability and speed of two-way retraction are improved.

[0046] In another embodiment of the present application, please refer to Figure 4 and Figure 5 The first movable lock tongue 13 / the second movable lock tongue 23 includes a sliding sleeve 231, an inner elastic member 232, an outer elastic member 233 and a limiting rod 234. A limiting platform 235 is arranged on the side of the sliding sleeve 231. The inner elastic member 232 is arranged in the sliding sleeve 231. The outer elastic member 233 is sleeved on the side of the sliding sleeve 231. One end of the limiting rod 234 is located in the sliding sleeve 231 and connected with the inner elastic member 232, and the other end abuts against the first ratchet 112 / the second ratchet 212.

[0047] It can be understood that the first movable lock tongue 13 / the second movable lock tongue 23 adopts a double elastic member structure. When the first lock body 10 and the second lock body 20 are combined, the first ejector pin 14 / the second ejector pin 24 pushes the second movable lock tongue 23 / the first movable lock tongue 13 as a whole to approach the second ratchet 212 / the first ratchet, so that the limiting rod 234 abuts against the first ratchet 112 / the second ratchet 212. At this time, the limiting rod 234 is engaged with the ratchet. When the tightening belt 30 is released, the limiting rod 234 and the ratchet are engaged. The pressure angle of the ratchet is 90° to form a self-locking function, that is, the force applied by the ratchet to the limit rod 234 is 90° to the extension and retraction direction of the limit rod 234; when tightening the tightening belt 30, the pressure angle between the limit rod 234 and the ratchet is less than 90°, and the component of the force applied by the ratchet to the limit rod 234 can push the limit rod 234 to contract, while compressing the inner elastic part 232, causing the ratchet to rotate, thereby tightening the tightening belt 30. After the tightening belt 30 is tightened into place, the inner elastic part 232 pushes the limit rod 234 to reset, and the limit rod 234 continues to limit the one-way braking of the ratchet.

[0048] In another embodiment of the present application, please refer to Figure 6 The first winding core 111 / the second winding core 211 includes a coil spring 1111 and a winding shaft 1112, the coil spring 1111 is arranged at one end of the winding shaft 1112, the first ratchet 112 / the second ratchet 212 is arranged at the other end of the winding shaft 1112, and the tightening belt 30 is wound in the middle of the winding shaft 1112.

[0049] It is understandable that a pair of limiting components is formed by using the coil spring 1111 and the ratchet wheel, so that the tightening belt 30 will not interfere with other components during the winding process, so that the winding and releasing process of the tightening belt 30 remains stable.

[0050] For further information, please also refer to Figure 6 At least one end of the reel 1112 is provided with a rotational matching structure 1113 .

[0051] It can be understood that, in order to accelerate the retraction and release of the tightening belt 30 during use, the active retraction and release mechanism on the manipulator can cooperate with the rotating matching structure 1113 to provide external force for the reel 1112 to accelerate the rotation, so as to increase the tightening efficiency of the goods and the resetting recovery efficiency of the separate braking recovery customs lock 100 after the goods are unsealed.

[0052] For further information, please also refer to Figure 6 The first winding core 111 / the second winding core 211 includes a limiting shell 1114, and the coil spring 1111 is arranged in the limiting shell 1114, and the coil spring 1111 is an inner coil spring.

[0053] It can be understood that after the coil spring 1111 adopts an inner coil spring, the inner coil spring can be arranged around the end of the reel 1112. During the process of tightening the tightening band 30, the inner coil spring rolls inward, and during the process of releasing the tightening band 30, the inner coil spring expands outward. At this time, the limiting shell 1114 can limit the inner coil spring to reduce space requirements while preventing the inner coil spring from interfering with the tightening band 30.

[0054] For further information, please also refer to Figure 6 A pressure detection unit 1115 is provided on the inner side of the limiting housing 1114 for detecting the expansion force of the inner coil spring.

[0055] It is understandable that, since the pressure detection unit 1115 is disposed on the inner side of the limit housing 1114, it can contact the periphery of the inner coil spring, and therefore, the expansion force of the inner coil spring can be detected. If the expansion force of the inner coil spring is less than the threshold value or is zero, the control panel of the separate brake recovery customs lock 100 can send out an alarm signal after receiving the pressure signal of the pressure detection unit 1115 to prompt that the release length of the tightening belt 30 has reached the upper limit, so as to prevent artificial stretching or excessive active winding of the manipulator external force, which may cause irreversible damage to the inner coil spring or winding assembly. Of course, the control panel of the separate brake recovery customs lock 100 can also predict the remaining amount of the tightening belt 30 in the first lock body 10 and the second lock body 20 in real time according to the pressure signal sent by the pressure detection unit 1115 in the first lock body 10 and the second lock body 20, and judge whether the separate brake recovery customs lock 100 is working properly.

[0056] Furthermore, the outer diameters of the reels 1112 of the first reel core 111 and the second reel core 211 are different.

[0057] It is understandable that when the internal force of the winding core is the same, if there is a slight deviation in the outer diameter of the winding shaft 1112 of the first winding core 111 and the second winding core 211, the rotation of the first ratchet 112 and the second ratchet 212 can cause staggered rotation during the process of retracting and releasing the tightening belt 30, which can prevent the probability event that the first movable lock tongue 13 and the second movable lock tongue 23 both hit the tooth peak of the ratchet, and ensure that the first lock body 10 and the second lock body 20 are docked in place every time. That is, when the first lock body 10 and the second lock body 20 are docked, even if one of the movable lock tongues hits the tooth peak of the ratchet, the other movable lock tongue can also push the ratchet to rotate slightly, so as to drive the tightening belt 30 to stretch slightly, and drive the ratchet that hits the tooth peak to deviate by half a tooth position, so that the first movable lock tongue 13 and the second movable lock tongue 23 are finally stuck in place, playing the role of automatically adjusting the tooth position.

[0058] In another embodiment of the present application, please refer to Figure 3 and Figure 7A limiting groove 121 is provided on the lock plug-in 12, and the locking mechanism 22 includes a power unit 221, a rocker rod 222 and an elastic return member 223. The power unit 221 is connected to the rocker rod 222, and the rocker rod 222 is connected to the elastic return member 223. The rocker rod 222 can be inserted into the limiting groove 121 under the action of the power unit 221.

[0059] It can be understood that after the lock plug 12 is inserted into the locking mechanism 22, the power unit 221 drives the rocker arm 222 to enter the limit groove 121 to complete the locking action, and the first lock body 10 and the second lock body 20 are completely fixed. After the power unit 221 is reset, the rocker arm 222 is synchronously reset under the elastic force of the elastic reset member 223, and the lock plug 12 can leave the locking mechanism 22, and the first lock body 10 and the second lock body 20 can be separated.

[0060] In another embodiment of the present application, please refer to Figure 8 The split braking recovery customs lock 100 also includes a near field communication unit 40 and a control board 50, and the near field communication unit 40 and the locking mechanism 22 are electrically connected to the control board 50 respectively.

[0061] It is understandable that the near field communication unit 40 can be an NFC sensing device. When the split brake recovery customs lock 100 is provided with the near field communication unit 40, the goods can be sensed by the NFC coils provided on both sides of the conveyor belt during the conveyor belt transportation, and the control panel 50 controls the locking mechanism 22 to perform the locking action. Of course, customs inspectors can also unlock the door by swiping an NFC card, which improves convenience.

[0062] In another embodiment of the present application, please refer to Figure 1 The first lock body 10 / the second lock body 20 also includes a shell 60, and a through hole (not shown) is provided on the shell 60. The two ends of the tightening belt 30 are respectively rolled up on the first winding core 111 and the second winding core 211 through the through hole.

[0063] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
