Both the left sliding hole 104 and the right sliding hole 109 are cylindrical through holes used to install the sliding rod. A clamping block 102 is connected to the middle of the upper end of the movable block 101 via a clamping bolt 103. The clamping block 102 is a rectangular block structure, and its lower surface is tightly fitted to the upper surface of the movable block 101. The clamping bolt 103 passes through the middle of the clamping block 102 and is connected to the clamping threaded hole 9 on the moving block 101. The clamping force between the clamping block 102 and the moving block 101 can be adjusted by rotating the clamping bolt 103.
[0021] The left and right ends of the moving block 101 are provided with left locking blocks 106 and right locking blocks 107 respectively through locking bolts 111. The left locking blocks 106 and the right locking blocks 107 are both block-shaped structures, and are respectively located on the left and right sides of the moving block 101. The locking bolts 111 pass through the left locking blocks 106 and the right locking blocks 107, and are connected with the threaded holes on the two sides of the moving block 101, for fixing the left locking blocks 106 and the right locking blocks 107 on the moving block 101. The connection between the moving block 101 and the left locking blocks 106 is provided with a left threading hole 105, and the connection between the moving block 101 and the right locking blocks 107 is provided with a right threading hole 108. The left threading hole 105 and the right threading hole 108 are both circular through holes, for the rope 10 to pass through. A threaded hole 110 is provided in the middle of the moving block 101, and the threaded hole 110 is a threaded through hole passing through the upper and lower surfaces of the moving block 101, for installing the worm screw 6.
[0022] The left and right sliding holes 104 and 109 are respectively provided with left and right sliding rods 4 and 7 for the up and down movement of the moving block 101. The left and right sliding rods 4 and 7 are both cylindrical rod-shaped structures, and their diameters are slightly smaller than the inner diameters of the left and right sliding holes 104 and 109, so that the moving block 101 can slide up and down along the left and right sliding rods 4 and 7. The lower ends of the left and right sliding rods 4 and 7 are fixed on the base, and the upper ends are fixedly provided with upper fixing assemblies 3 through fixing bolts 2.
[0023] The threaded hole 110 is provided with a worm screw 6 for driving the up and down movement of the moving block 101. The worm screw 6 is a cylindrical rod-shaped structure with threads, and its external threads match the internal threads of the threaded hole 110. The lower end of the worm screw 6 passes through the threaded hole 110, and the upper end is movably connected with the upper fixing assembly 3. The worm screw 6 is provided with a locking nut 8 for locking the worm screw 6. The locking nut 8 is an annular structure, and its internal threads match the external threads of the worm screw 6. By rotating the locking nut 8, the worm screw 6 can be locked at a specific position. The lower end of the pressing block 102 is located on the upper end of the locking nut 8, and when the pressing block 102 is pressed down, additional pressure can be applied to the locking nut 8, further ensuring the stability of the position of the worm screw 6. The end of the worm screw 6 is provided with a torque wrench 5 for rotating the worm screw 6. The torque wrench 5 is a hand tool, and one end of the torque wrench 5 is connected with the end of the worm screw 6. By rotating the torque wrench 5, the worm screw 6 can be driven to rotate, thereby driving the moving block 101 to move up and down.
[0024] The upper fixing assembly 3 comprises a fixing block 301, a right pressing block 302, a right upper threading hole 303, a guide groove 304, a left upper threading hole 305, and a left pressing block 306. The fixing block 301 is a rectangular block structure, and the lower end thereof is fixedly connected with the top ends of the left sliding rod 4 and the right sliding rod 7 through the fixing bolt 2. The upper end of the fixing block 301 is fixedly provided with an arc-shaped guide rail 302, and the arc-shaped guide rail 302 is an arc-shaped structure, and the upper end thereof is provided with the guide groove 304. The guide groove 304 is a groove extending along the arc-shaped guide rail 302, and is used for guiding the movement of the rope 10. The two ends of the fixing block 301 are respectively provided with the left pressing block 306 and the right pressing block 302. The left pressing block 306 and the right pressing block 302 are both block structures, and are respectively located on the left side and the right side of the fixing block 301. The connecting position of the fixing block 301 and the left pressing block 306 is provided with the left upper threading hole 305, and the connecting position of the fixing block 301 and the right pressing block 302 is provided with the right upper threading hole 303. The left upper threading hole 305 and the right upper threading hole 303 are both circular through holes, and are used for the rope 10 to pass through.
[0025] In the embodiment, the rope 10 is a flexible rope, one end of the rope 10 passes into the left upper threading hole 305, the other end of the rope 10 passes out of the right upper threading hole 303 after passing through the guide groove 304, and the two ends of the rope 10 are wound around the goods for one turn, one end of the rope 10 passes out of the left threading hole 105, and the other end of the rope 10 passes out of the right threading hole 108. By adjusting the position of the movable tension adjusting assembly 1, the tightness of the rope 10 can be changed.
[0026] The working principle of the rope tightness adjusting device in the embodiment is as follows: first, the rope 10 is threaded through the upper fixing assembly 3 and the movable tension adjusting assembly 1 according to the above path, the locking nut 8 and the pressing block 102 are loosened, then the worm screw 6 is rotated by using the torque wrench 5, since the worm screw 6 is threadedly connected with the threaded hole 110 of the moving block 101, the rotation of the worm screw 6 drives the moving block 101 to move up and down along the left sliding rod 4 and the right sliding rod 7; when the moving block 101 moves downward, the rope 10 is tightened; when the moving block 101 moves upward, the rope 10 is loosened; when the required tightness is reached, the locking nut 8 is rotated to lock the worm screw 6 at the current position; finally, the pressing block 102 is further fixed by rotating the pressing bolt 103 to press downward.
[0027] The rope tightness adjusting device in the embodiment has the characteristics of simple structure, convenient operation, and accurate adjustment. The fine adjustment of the tightness of the rope 10 can be realized through the precise thread of the worm screw 6; the long-term stability of the tightness of the rope 10 can be ensured through the double locking of the locking nut 8 and the pressing block 102; the stability of the moving block 101 during the upward and downward movement can be ensured through the bidirectional guidance of the left sliding rod 4 and the right sliding rod 7, and the moving block 101 will not deviate or shake.
[0028] Embodiment two
[0029] The embodiment is basically the same as embodiment one, except that the worm screw 6 is provided with a locking nut 8 for locking the worm screw 6. The locking nut 8 is a hexagonal nut with an inner diameter matching the outer diameter of the worm screw 6. By rotating the locking nut 8, it can be fastened at any position on the worm screw 6. The upper surface of the locking nut 8 is in contact with the lower surface of the pressing block 102. When the pressing block 102 is pressed down by the pressing bolt 103, additional pressure is applied to the locking nut 8, further enhancing the locking effect.
[0030] Embodiment three
[0031] The embodiment is basically the same as embodiment one, except that the worm screw 6 and the fixed block 301 are movably connected. Specifically, a circular groove is provided at the bottom center of the fixed block 301, and the top end of the worm screw 6 is a spherical structure that fits into the circular groove at the bottom of the fixed block 301, forming a ball-and-socket joint. This connection allows the worm screw 6 to rotate freely within a certain angle range, but it will not fall off the fixed block 301. This movable connection increases the flexibility of the device, allowing the rope 10 to maintain appropriate tension at different angles.
[0032] Embodiment four
[0033] The embodiment is basically the same as embodiment one, except that a pressing threaded hole 9 is provided at the connection between the pressing bolt 103 and the moving block 101. The pressing threaded hole 9 is a threaded hole that penetrates the upper surface of the moving block 101, with internal threads matching the external threads of the pressing bolt 103. By rotating the pressing bolt 103, the pressing force of the pressing block 102 on the rope 10 can be adjusted. The depth of the pressing threaded hole 9 is sufficient to allow the pressing bolt 103 to be securely fixed on the moving block 101, ensuring stable and reliable pressing effect.
[0034] Embodiment five
[0035] The embodiment is basically the same as embodiment one, except that the lower end of the pressing block 102 is located on the upper end of the locking nut 8. Specifically, a groove is provided on the lower surface of the pressing block 102, which matches the shape of the upper surface of the locking nut 8. When the pressing block 102 is pressed down, the groove on the lower surface of the pressing block 102 tightly fits the upper surface of the locking nut 8, not only fixing the rope 10, but also applying additional pressure to the locking nut 8 to prevent it from loosening due to vibration or external force. This double locking mechanism greatly improves the stability and reliability of the device.
[0036] Embodiment six
[0037] The embodiment is basically the same as embodiment one, with the difference that a torque wrench 5 is arranged at the end of the worm screw 6 to rotate the worm screw 6. One end of the torque wrench 5 is connected with the end of the worm screw 6, and the other end is convenient to hold and apply force. The connection between the torque wrench 5 and the worm screw 6 adopts a hex sleeve connection mode, the end of the worm screw 6 is hexagonal, and the connecting end of the torque wrench 5 is a matching hexagonal groove. This connection mode ensures that the torque wrench 5 will not slip when rotating the worm screw 6, and the transmission torque efficiency is high. The length of the crossbar of the torque wrench 5 is moderate, which can provide enough torque and will not cause inconvenience due to being too long.
[0038] It should be noted that embodiment one, embodiment two, embodiment three, embodiment four, embodiment five, and embodiment six are all a kind of rope tightness adjusting device.
[0039] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions described in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
