[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0028] Example:
[0029] Reference Figures 1-6, a rope tightening device, including a mounting shell 1 with a cavity 101 formed in the center for accommodating a rope and a structure for winding the rope, a main shaft at the center of the cavity 101, and a corresponding cylindrical cavity at the center of the winding disk, the main shaft to ensure that the rotation position of the winding disk remains unchanged, a threading groove 103 is opened on the mounting shell 1, and the threading groove 103 connects the cavity 101 with the outside world to facilitate the insertion and exit of the rope, and also includes: a winding disk rotatably connected to the inside of the mounting shell 1 for winding or releasing the rope wire, wherein a lock is slidably connected to the winding disk for one-way locking of the winding disk, that is, when the lock locks the winding disk The wire is wound around the wire and the spool is locked, so the wire is not wound around the wire and the spool is locked.
[0030] In the above design, the lock is controlled by sliding to lock the winding reel in one direction, which is simple and convenient, and the lock can be unlocked by simply pressing the unlocking part, thereby releasing the wound wire, making the winding, adjustment and locking of the wire more convenient and without jamming.
[0031] Specifically, the locking member includes a guide block 302 that is slidably connected to the winding reel, and a ratchet 301 is provided at the end of the guide block 302. An inner ratchet 102 that cooperates with the ratchet 301 is provided in the mounting shell 1. When the ratchet 301 engages with the inner ratchet 102, the winding reel can be controlled to rotate in only one direction, and the sliding engagement method can make locking simpler and more efficient.
[0032] The lock also includes a guide rod 3 arranged on the winding disk, the end of the guide rod 3 extends into the guide block 302, and a spring 304 is sleeved on the guide rod 3. The spring 304 is used to apply a thrust to the guide block 302 away from the axis of the winding disk, and the thrust of the spring 304 is used to keep the ratchet 301 and the inner ratchet 102 in a meshing state at all times. In addition, magnetic material can also be used for the sliding power of the guide block 302. For example, the ends of the ratchet 301 and the guide rod 3 are magnets with the same magnetic properties. In this way, when the guide rod 3 is stationary, the ratchet 301 tends to move away from the guide rod 3, thereby ensuring that the ratchet 301 and the inner ratchet 102 are in a meshing state at the same time.
[0033] Specifically, the unlocking portion includes a pressure plate 4, a conical block 401 is fixedly connected to the pressure plate 4, a driving surface 303 is provided on the guide block 302, the conical block 401 cooperates with the driving surface 303, and the driving surface 303 here is an inclined surface, and its inclination angle is consistent with the inclination angle of the contact surface of the conical block 401. When the pressure plate 4 is subjected to pressure in the direction of the winding drum, that is, Figure 4 In the direction of force F, the conical block 401 drives the guide block 302 to move closer to the axis of the winding drum, so that the ratchet 301 is disengaged from the inner ratchet 102, and the winding drum can rotate freely. Here, its main purpose is to release the wound rope and wire.
[0034] In addition, it also includes a cylindrical button 5, one end of which is in contact with the pressure plate 4, and the other end extends to the top through the drive shell 6. By pressing the button 5, the pressure F is transmitted to the pressure plate 4, thereby realizing the unlocking function, which is more convenient to use and has stable force transmission.
[0035] The winding disk includes a supporting disk 2 and a winding column disk 204 fixedly connected to the supporting disk 2. The winding column disk 204 is provided with a threading hole 205 for fixing both ends or one end of the wire. At the same time, the wire passes through the threading groove 103 to bind foreign objects. The top of the supporting disk 2 is fixedly connected to the limiting plate 201, and the guide rod 3 passes through the limiting plate 201. The limiting blocks 202 are symmetrically arranged on both sides of the limiting plate 201. The guide block 302 is restricted by the two limiting blocks 202 on both sides and can only move along the axial direction of the guide rod 3, that is, the ratchet 301 is engaged and separated with the inner ratchet 102. The movement mode is simpler, there will be no jamming phenomenon, and the frequency of damage is reduced.
[0036] The supporting plate 2 is fixedly connected with the pin column 203, and the driving shell 6 is fixedly connected with the pin cylinder 602. The pin column 203 is engaged with the pin cylinder 602. The circumferential surface of the driving shell 6 is provided with anti-slip grooves 601. The fingers are held on the anti-slip grooves 601 to rotate the driving shell 6, so that the rotation angle is more accurate and stable, and the pin connection method is more stable and also convenient for disassembly, replacement or maintenance.
