[0018] The present application embodiment discloses a jacking type flexible wire lock. Figure 1 , Figure 2 , including a main housing 1, in which a motor 2 is detachably fixedly connected by bolts, so that the motor 2 is connected to the main housing 1 and connected to the main housing 1 to form a whole. The output shaft of the motor 2 is threadedly connected with a slider 4, and a first limiting groove is provided in the main housing 1. The slider 4 is slidably connected in the first limiting groove, so that the slider 4 is limited by the first limiting groove, so that the motor 2 is powered on and its output shaft rotates to drive the slider 4 to move along the first limiting groove. The motor 2 is connected to a control module assembly, which is a common single-chip control circuit board module on the market, so that the control module assembly controls whether the motor 2 is powered on and whether the motor 2 is controlled to rotate forward or reverse. A battery 16 is fixedly connected in the main housing 1, and the battery 16 is electrically connected to the motor 2 and the control module assembly, so that the battery 16 provides power to the motor 2 and other electronic components, and at the same time, the control module assembly controls whether the battery 16 powers the motor 2 and other electronic components.
[0019] Reference Figure 1 , Figure 2The first travel switch 3 and the second travel switch 12 that match the slider 4 are detachably fixedly connected in the main housing 1 by bolts, so that the first travel switch 3 and the second travel switch 12 are connected to the main housing 1 to form a whole. The first travel switch 3 and the second travel switch 12 are electrically connected to the battery 16 and the control module assembly, so that the battery 16 supplies power to the first travel switch 3 and the second travel switch 12, and the control module assembly receives and processes the electrical signal when the first travel switch 3 and the second travel switch 12 are triggered. The first trigger plate 13 and the second trigger plate 14 extend on both sides of the slider 4, so that the first trigger plate 13 and the second trigger plate 14 are connected to the slider 4, so that they move with the slider 4 at the same time. The first travel switch 3 and the second travel switch 12 are respectively detachably fixed in the main housing 1 by bolts, and are located in the end surface direction where the first trigger plate 13 and the second trigger plate 14 are away from each other, so that the first travel switch 3 and the second travel switch 12 are respectively connected to the main housing 1 at both ends of the first trigger plate 13 and the second trigger plate 14, thereby realizing the movement of the slider 4 relative to the motor 2 in the direction away from or close to each other. When the first trigger plate 13 moves to conflict with the first travel switch 3, an electric signal is generated, and the motor 2 is controlled to stop working through the control module assembly. When the second trigger plate 14 moves to conflict with the second travel switch 12, an electric signal is generated, and the motor 2 is controlled to stop working through the control module assembly.
[0020] Reference Figure 1 , Figure 2 A pair of lock core switches 10 are slidably connected in the main housing 1, and the two lock core switches 10 are in conflict with the slider 4, so that the two lock core switches 10 are pushed to move by the movement of the slider 4. Specifically, a second limit groove 15 connected to the first limit groove is provided in the main housing 1, and the vertical section of the second limit groove 15 is T-shaped. The vertical section of the lock core switch 10 is T-shaped. The lock core switch 10 is slidably connected in the second limit grooves 15 on both sides of the first limit groove, so that the lock core switch 10 is limited by the second limit groove 15, and when the slider 4 moves in the direction close to the lock core switch 10, it can drive the lock core switch 10 to move to both sides. The two sides of the end of the slider 4 away from the motor 2 are inclined surfaces, and the end surfaces where the two lock core switches 10 are close to each other are inclined surfaces. The two inclined end surfaces of the slider 4 respectively conflict with the inclined surfaces of the two lock core switches 10, so that the inclined surfaces on both sides of the slider 4 cooperate with the inclined surfaces of the two lock core switches 10, so that when the slider 4 moves in the direction close to the lock core switch 10, it can drive the lock core switch 10 to move to both sides.
[0021] Reference Figure 1 , Figure 2A lock assembly for locking the steel wire rope 5 is connected to the main housing 1, so that the steel wire rope 5 can be locked or unlocked by the lock assembly, thereby realizing the supervision and locking of the flexible steel wire lock on the object, and the entire flexible steel wire lock can be reused. The lock assembly is connected to the lock core switch 10, so that the lock assembly is driven to move by the movement of the lock core switch 10 to achieve the locking or unlocking of the steel wire rope 5. The lock assembly includes a lock shell 7, a lock core 8, a spring 6 and a steel ball 9 arranged in pairs. The lock shell 7 is detachably fixedly connected to the main housing 1 on both sides of the two lock core switches 10 by bolts, so that the two lock shells 7 are connected to the main housing 1 to form a whole. A moving hole is opened in the end faces of the two lock shells 7 that are far away from each other, and the lock core 8 and the spring 6 are arranged in the moving hole, so that the spring 6 and the lock core 8 are placed through the moving hole, and the lock core 8 and the spring 6 can move relative to the lock shell 7. The outer end surface of the lock core 8 extends with a limiting protrusion, and the spring 6 is partially sleeved outside the lock core 8, and one end conflicts with the limiting protrusion, and the other end conflicts with the side wall of the main housing 1, so that the spring 6 is limited by the limiting protrusion, so that the spring 6 can provide elastic force for the lock core 8, so that the lock core 8 is always away from the side end surface of the main housing 1 under the elastic force of the spring 6. A plurality of mounting holes are provided on the lock core 8, and the steel ball 9 is arranged in the mounting holes, and the outer end surface diameter of the mounting hole is smaller than the diameter of the steel ball 9, so that the steel ball 9 is placed in the plurality of mounting holes and prevented from being separated from the outer end surface of the mounting hole. The inner wall of the moving hole away from the end of the spring 6 is an inclined end surface, so that when it moves to the inclined end surface of the moving hole, the steel ball 9 can be pressed back into the mounting hole, so that the other end of the steel ball 9 can conflict with the steel wire rope 5, thereby locking the steel wire rope 5. The end faces of the two lock shells 7 that are close to each other are provided with through holes connected to the movable holes. Parts of the two lock core switches 10 extend into the through holes and interfere with the lock core 8, so that the lock core 8 is moved by the movement of the lock core switch 10, so that the steel ball 9 can move with the lock core 8 to a place with a larger diameter of the movable hole, thereby realizing that the steel wire rope 5 can drive the steel ball 9 to move in the installation hole, thereby realizing the unlocking of the steel wire rope 5.
[0022] Reference Figure 1 , Figure 2 One end of the steel wire rope 5 is detachably fixedly connected to a fixing block 11 in the main housing 1 by bolts, so that the fixing block 11 is connected to one end of the steel wire rope 5, thereby limiting one end of the steel wire rope 5 and preventing it from being separated from the main housing 1. A lock hole is provided on the main housing 1, and the other end of the steel wire rope 5 passes through the lock hole, the moving hole and the through hole, and extends to the outside of the main housing 1, so that the steel wire rope 5 passes through the main housing 1 and the lock assembly through the lock hole, so that the lock assembly can lock the steel wire rope 5.
[0023] When it is necessary to lock the wire rope 5, the slider 4 moves to a position close to the first stroke switch 3 and away from the second stroke switch 12 under the drive of the motor 2. At this time, the inclined surface matching space between the slider 4 and the lock core switch 10 becomes larger, thereby leaving space for the lock core switch 10 to move. At this time, the lock core 8 moves in the direction close to the lock core switch 10 under the action of the spring 6, and at the same time drives the steel ball 9 to move in the lock shell 7. Under the action of the inclined surface of the moving hole, the steel ball 9 conflicts with the wire rope 5, thereby locking the wire rope 5; when the device needs to loosen the wire rope 5, the slider 4 leaves the second stroke switch 12 and approaches the first stroke switch 3 under the drive of the motor 2. At this time, the lock core switch 10 drives the lock core 8 to move under the action of the slider 4 and the matching inclined surface. At this time, the spring 6 is compressed, and the lock core 8 drives the steel ball 9 to move at the same time, and moves to a place where the diameter of the inclined surface is larger, and the steel wire rope 5 is loosened by the action of the inclined surface of the inner wall of the lock shell 7. At this time, it is in the unlocked state.
[0024] Unless otherwise specified, the device elements involved in the above embodiments are all conventional device elements, and the structural settings, working modes or control modes involved are all conventional settings, working modes or control modes in the art unless otherwise specified.
[0025] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
