[0027] Figures 1-5 The utility model discloses a kind of convenient fast-adjusting lifting self-locking devices, which is shown schematically.

[0028] A convenient fast-adjusting lifting self-locking device, comprising a mutually buckling upper cover 1 and lower cover 2, further comprising sliding channel 3 opened in upper cover 1 and lower cover 2;

[0029] Rope 31 is slidably arranged in sliding channel 3, and rope 31 slides in sliding channel 3. The inner diameter of sliding channel 3 is consistent with the size of rope 31, which can increase the stability of rope 31 when sliding;

[0030] The compression block 4 is arranged between the upper cover and the lower cover 2, the compression block 4 is provided with a torsion spring 42 for automatic reset after rotation, the torsion spring 42 is located between the lower cover 2 and the compression block 4, and when the compression block 4 is rotated with the torsion spring 42, the compression block 4 can make the compression block 42 on the inner side wall of the upper cover 1 and the lower cover 2 rotate, and when the compression block 42 rotates, the compression block 4 is driven to rotate by engaging with the teeth on the compression block 4, so that the compression block 4 is away from the inner side wall of the upper cover 1 to release the limiting effect on the rope 31.

[0031] Combining Figures 2-3 As shown in the figure, the rotating block 42 is internally provided with a through hole 421 through which the rope 31 can pass vertically.

[0032] In this embodiment, when the rope 31 passes through the through hole 421, the lower end of the rope 31 is grabbed, and then it is swung left and right to control the rotation of the rotating block 42, so as to control the compression of the compression block 4 and the release of the rope 31.

[0033] Combining Figure 4 As shown in the figure, the upper cover 1 and the lower cover 2 are jointly provided with a sliding groove 5, the sliding groove 5 is slidably provided with an anti-skid block 51, and the side of the anti-skid block 51 close to the rope 31 is provided with an anti-skid convex pattern 52.

[0034] In this embodiment, the anti-skid block 51 is located in the sliding groove 5 on the side of the lower cover 2 in the initial state, when the rope 31 is too thin, in order to reduce the distance between the compression block 4 and the side wall of the lower cover 2 and the upper cover 1 to increase the clamping stability of the rope 31, at this time, the anti-skid block 51 is slid out of the sliding groove 5, and the anti-skid convex pattern 52 on the anti-skid block 41 and the anti-skid block 51 can better clamp the rope and increase the friction.

[0035] Combining Figure 1 As shown in the figure, the side of the anti-skid block 51 away from the rope 31 is provided with a dial block 53, and the upper cover 1 and the lower cover 2 are provided with a dial block sliding groove 54, and the dial block 53 slides in the dial block sliding groove 54.

[0036] In this embodiment, the dial block 53 can be slid in the dial block sliding groove 54, so as to drive the anti-skid block 51 to slide, thereby realizing the function of clamping the rope 31 of different thickness, and improving the clamping effect.

[0037] Combining Figure 3 As shown in the figure, the two ends 31 of the sliding channel 3 are gradually enlarged from top to bottom.

[0038] In this embodiment, the design of gradually expanding the two ends 31 of the sliding channel 3 from top to bottom can increase the range of motion for the lower end of the rope 31, thereby preventing the rope 31 from repeatedly rubbing against the edges of the upper cover 1 and the lower cover 2 when the lower end shakes after hanging objects, affecting the service life of the rope 31 and resulting in lower safety of the rope 31.

[0039] Combine Figure 2 As shown, the pressing block 4 and the rotating block 42 are respectively sleeved on two rotating shafts 43 between the upper cover 1 and the lower cover 2, and the pressing block 4 and the rotating block 42 are driven by gear engagement.

[0040] In this embodiment, the transmission mode of tooth meshing makes the transmission efficiency more stable, the service life longer, and the safety better.

[0041] As shown in the figure, a pressing bevel tooth 55 is provided on one side of the pressing block 4 close to the anti-sliding block 51. After the pressing bevel tooth 55 cooperates with the anti-sliding block 51, the pressing bevel tooth 55 runs from the lower left to the upper right.

[0042] In this embodiment, this design can enable the tooth tips of the tightening bevel teeth 55 to better squeeze the rope 31 when the right end of the tightening rope 31 is pulled downward, thereby increasing friction, improving the clamping effect and increasing safety.

[0043] Combine Figure 5 As shown, the upper cover 1 and the lower cover 2 are both provided with a through hole 6 , and the through hole 6 is located on the side of the upper cover 1 and the lower cover 2 .

[0044] In this embodiment, the design of adding the insertion hole 6 can better thread the rope compared to the upper cover 1 and the lower cover 2 with completely closed sides, thereby increasing the convenience of rope threading.

[0045] How it works

[0046] When in use, the rotating block 42 is lifted upward, the rotating block 42 drives the pressing block 41 to move away from the anti-skid block 51 and to be separated from the anti-skid block, at this time, the torsional spring 42 stores energy, then the rope 31 is inserted into the sliding channel 3 in the upper cover 1 and the lower cover 2, at this time, the right end and the lower end of the rope 31 are hung on an article, at this time, the two ends of the rope 31 are vertically stretched downward under the force, at this time, the rotating block 42 can be driven to move to tightly press the rope 31 on the right side wall of the upper cover 1 and the lower cover 2 through the gear and the pressing block 4, when the length of the rope 31 needs to be adjusted, the left end of the rope 31 is moved to the left, at this time, the rotating block 42 is rotated clockwise, thereby the pressing block 4 is separated from the rope 31, at this time, the adjustment of the rope 31 is realized, which is convenient and fast, when the rope 31 is used for a long time, the rope 31 is thinned or passes through the rope 31 with a smaller diameter, the anti-skid block 41 is slid out of the sliding groove 5 in the lower cover 2, at this time, the distance between the pressing block 41 and the right side wall of the combination of the upper cover 1 and the lower cover 2 is small, at this time, the thinner rope 31 is clamped, the universality of the utility model is improved, and the function of clamping the rope 31 with different sizes is realized.

[0047] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model, any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
