[0028] The following is combined with Figure 1-7 This application is described in further detail.

[0029] The present application embodiment discloses a reusable sealing lock structure. Figure 1-7 A reusable locking structure includes a lock body shell 1, an internal lining plate 2, a steel wire lock rope 3, a lock rope fixing block 4, a self-locking lock block 5 and a locking member 6.

[0030] Reference Figure 1 , Figure 2 and Figure 3 A mounting opening for mounting the internal lining plate 2 is reserved at the bottom of the lock body shell 1. A bottom cover plate 11 is provided at the bottom of the lock body shell 1. The bottom cover plate 11 is fixedly connected to the lock body shell 1 with pins, and the lock body shell 1 is sealed by the bottom cover plate 11.

[0031] Reference Figure 1 , Figure 2 and Figure 4 The inner lining plate 2 is fixedly installed in the lock body shell 1. The lock rope fixing block 4 is located on one side of the top of the inner lining plate 2 and is fixedly connected to the inner lining plate 2. One end of the steel wire lock rope 3 is fixedly connected to the lock rope fixing block 4, and the other end vertically penetrates the lock body shell 1 and slides freely. The self-locking lock block 5 is fixedly connected to the inner lining plate 2 by screws. A straight through hole 51 is vertically penetrated on the self-locking lock block 5. The end of the steel wire lock rope 3 away from the lock rope fixing block 4 passes through the straight through hole 51 and extends to the outside of the lock body shell 1.

[0032] Reference Figure 4 , Figure 5 and Figure 6The locking member 6 is installed on the inner lining plate 2, and the locking member 6 is located on one side of the self-locking lock block 5. The locking member 6 includes a spring 62, a steel ball 61, a slider 63 and a driving part. An oblique through hole 52 for installing the spring 62 is provided inside the self-locking lock block 5. The upper end of the oblique through hole 52 is connected with the straight through hole 51. The spring 62 is installed in the oblique through hole 52. The steel ball 61 is located in the oblique through hole 52, and the steel ball 61 is arranged at the top of the spring 62. A slide groove 23 is provided on the surface of the inner lining plate 2. The slider 63 is slidably connected in the slide groove 23. The sliding direction of the slider 63 is parallel to the length direction of the oblique through hole 52. One end of the spring 62 extends outside the oblique through hole 52 and is fixedly connected to the slider 63. When installing the spring 62, one end of the spring 62 is screwed into the fixing hole of the slider 63, and the other end is extended into the oblique through hole 52 of the self-locking lock block 5 to support the steel ball 61 inside the oblique through hole 52.

[0033] Reference Figure 4 , Figure 5 and Figure 6 The driving part includes a motor 64, a screw 65 and a bearing 66. A pressing plate 21 is provided on the inner lining plate 2. The pressing plate 21 is fixedly connected to the inner lining plate 2 by screws. The motor 64 is located between the pressing plate 21 and the inner lining plate 2. The pressing plate 21 is used to press the motor 64 below, fix and crush the motor 64, and prevent the motor 64 from rotating. The output shaft of the motor 64 is coaxially fixedly connected with the screw 65 by a coupling. The screw 65 penetrates the slider 63 and is threadedly connected to the slider 63. The bearing 66 is clamped at the end of the slide 23, and the end of the screw 65 is rotatably connected to the bearing 66. The motor 64 drives the screw 65 to rotate through the coupling. The rotation of the screw 65 drives the screw 65 slider 63 to perform reciprocating linear motion in the slide 23, converting the rotating motor 64 motion into forward and backward linear motion. The bearing 66 and the motor 64 are respectively the commercially available MR63 thin 3×6×2mm bearing 66 and the mini 610 hollow cup 6mm diameter 4-stage reduction motor 64.

[0034] Reference Figure 4 , Figure 5 and Figure 7 , a baffle cover plate 22 is provided on the inner lining plate 2, and the baffle cover plate 22 is fixedly connected to the inner lining plate 2 by screws, and the locking member 6, the self-locking lock block 5, and the pressure plate 21 are located between the baffle cover plate 22 and the inner lining plate 2. Below the baffle cover plate 22 are the driving parts such as the motor 64. The purpose of setting the baffle cover plate 22 is to prevent foreign matter from entering the transmission part. Ensure the stability and reliability of the transmission part, and facilitate the grease application later. The side of the baffle cover plate 22 is used to place the battery, so the cover plate is also for leveling, so that the battery is at the same height as the transmission part on this side.

[0035] Reference Figure 1 , Figure 4 and Figure 7After the locking member 6, the self-locking lock block 5 and the inner lining plate 2 are installed, the inner lining plate 2 is pushed into the lock body shell 1 from the installation opening at the bottom of the lock body shell 1, and then the bottom cover plate 11 is fixedly connected with the lock body shell 1 by pins, and the assembly of the lock is completed. The lock body cannot be disassembled after the pins are sealed, thereby preventing the lock body from being opened or damaged manually.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The front of the lock body shell 1 is provided with an antenna interface and an antenna port cover plate 12 for blocking the antenna interface, and the back of the lock body shell 1 is provided with a wireless charging interface and a charging coil cover plate 13 for blocking the wireless charging interface. The antenna port cover plate 12 is used to connect the communication antenna, and the charging coil cover plate 13 is used for charging the lock body, so the antenna port cover plate 12 and the charging coil cover plate 13 are both made of non-metallic materials.

[0037] Reference Figure 3 and Figure 4 The lock body shell 1 and the bottom cover plate 11 are provided with a sealing gasket 14 at the movable part of the wire lock rope 3. The sealing gasket 14 is convex, and it is sealed and waterproof, and prevents artificial damage and removal of the sealing gasket 14. Therefore, the design is a convex sealing gasket 14 that rotates from the inside to the outside.

[0038] The implementation principle of a reusable locking structure of the embodiment of the present application is as follows: in the initial locking state: one end of the steel wire lock rope 3 is fixed on the lock rope fixing block 4, and the other end passes through the straight hole 51 of the self-locking lock block 5 and extends to the outside of the lock body shell 1. In the unlocked state, the spring 62 in the locking member 6 pushes the steel ball 61 into the oblique through hole 52 of the self-locking lock block 5, and the steel ball 61 clamps the steel wire lock rope 3 at the top of the oblique through hole 52, thereby locking the lock rope.

[0039] Unlocking process: When unlocking is required, the motor 64 is started, and the output shaft of the motor 64 drives the screw rod 65 to rotate. The screw rod 65 is threadedly connected to the slider 63, and the rotation of the screw rod 65 causes the slider 63 to perform linear motion in the slide groove 23 of the inner lining plate 2.

[0040] The linear motion of the slider 63 drives the spring 62 and the steel ball 61 to move in the oblique through hole 52, and the steel ball 61 slides downward from the oblique through hole 52 and no longer blocks the wire lock rope 3. At this time, the wire lock rope 3 can slide freely to achieve the unlocking operation.

[0041] This design cleverly uses the friction between the steel ball 61 and the steel wire rope 3. When the lock is closed, the motor 64 rotates through the coupling to drive the screw rod 65, and the screw rod 65 rotates with the slider 63 to make reciprocating linear motion in the slide groove 23. The slider 63 is connected to the spring 62, thereby driving the spring 62 to move up and down with the slider 63. After the lock is closed, the spring 62 moves into the self-locking lock block 5, pushing the steel ball 61 inside the self-locking lock block 5 to move inward, so that the steel ball 61 is in a position tangent to the steel wire rope 3. When the steel ball 61 is in place first, the steel wire rope 3 is inserted. At this time, the steel ball 61 will receive a downward dispersion force, press the spring 62 to contract, and complete the insertion of the steel wire rope 3. At this time, the lock rope can be inserted all the way without being affected. When the wire lock rope 3 is inserted first and then the motor 64 is driven to push the steel ball 61 into place, it is also possible. The motor 64 only needs to drive a small force to overcome the deformation of the spring 62 to complete the locking. The motor 64 will not get stuck and cannot be in place, and the fault tolerance is high.

[0042] After the lock is closed, there is static friction between the steel ball 61 and the steel wire rope 3, so when the steel wire rope 3 is pulled out, the steel ball 61 will move with the steel wire rope 3. At this time, the steel ball 61 will enter the triangular self-locking cavity of the self-locking lock block 5 together with the steel wire rope 3 to complete the self-locking lock. In this way, the greater the tension of the outer rope, the greater the friction between the steel ball 61 and the steel wire rope 3, and the stronger the self-locking locking effect. When unlocking, the motor 64 reverses the power supply, and pulls the spring 62 out of the self-locking lock block 5 through the external transmission component. At this time, it is only necessary to insert the lock rope steel wire rope a little bit to release the self-locking effect, and the steel ball 61 can fall back in the oblique through hole 52. At this time, there is no spring 62 to limit the static friction between the steel ball 61 and the steel wire rope 3, so the friction between the steel wire rope 3 and the steel ball 61 is not enough to drive the steel ball 61 to move together, so the steel wire rope 3 can be freely inserted and pulled out.

[0043] During the whole process, the spring 62 is only slightly compressed when the wire lock rope 3 is inserted and the lock is closed. Therefore, the motor 64 does not need a large torque to overcome the resistance of closing the lock. When unlocking, when the external wire lock rope 3 is stressed, the self-locking effect composed of the friction between the steel ball 61 and the wire lock rope 3 is utilized, which is completely separated from other transmission structures. Therefore, it will not affect the operation of other transmission devices such as the motor 64, and the unlocking is lighter and is not affected by the strength of the external force on the lock rope itself, which has a better use effect.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
