DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Embodiment 1, by Figure 1-6 The utility model relates to a foldable light pulley, comprising a plate body 1, an inner groove 2 is provided inside the plate body 1, a driving screw 3 is rotatably provided inside the inner groove 2, a knob 4 is fixedly provided at the top of the driving screw 3, a slide plate 5 is slidably provided in the inner groove 2, an integral rack 6 is connected to the slide plate 5, screw holes matching with the thread of the driving screw 3 are provided on the slide plate 5 and the rack 6, gears 7 are symmetrically rotatably provided inside the inner groove 2, an eccentric wheel 8 is fixedly provided on each gear 7, and a ring body 9 is rotatably provided on the eccentric wheel 8;

[0024] With this design, when the pulley needs to be used, the driving screw 3 is driven to rotate by the turning knob 4, the driving screw 3 drives the rack 6 to move through the thread, the rack 6 drives the gear 7 to rotate through meshing, and the gear 7 drives the eccentric wheel 8 to rotate, so that the eccentric wheel 8 extends out of the surface of the plate body 1 after rotation, and then can be moved through the ring body 9 on the eccentric wheel 8, which is more convenient. When not in use, the eccentric wheel 8 can be folded and stored to the outside of the plate body 1 in the same way, thereby reducing the space occupied for easy carrying.

[0025] The plate body 1 is provided with a receiving groove 101, the knob 4 is located inside the receiving groove 101, and the knob 4 is provided with a tool groove;

[0026] This design makes it easy for a tool to penetrate into the tool slot to drive the knob 4 to rotate.

[0027] The two eccentric wheels 8 are symmetrically arranged with the rack 6 as the center.

[0028] The outer side of the eccentric wheel 8 is connected to an integral annular block 801, and the inner side of the ring body 9 is provided with an annular groove 901, and the annular block 801 on the eccentric wheel 8 and the annular groove 901 on the ring body 9 are relatively slidably matched;

[0029] With this design, the ring body 9 is limited in position through the cooperation between the annular block 801 and the annular groove 901, thereby preventing the ring body 9 from being separated from the eccentric wheel 8.

[0030] Side grooves 102 are symmetrically formed on both sides of the plate body 1, and a connecting plate 103 is hinged inside the side groove 102, and a mounting hole 104 is formed on the connecting plate 103;

[0031] With this design, the connecting plate 103 can be installed at a desired position through the mounting hole 104 by simply rotating it to a horizontal position, which is very convenient.

[0032] The side groove 102 includes a first groove body 1021 and a second groove body 1022 connected to the first groove body 1021; the connecting plate 103 includes a first connecting block 1031 and a second connecting block 1032 integral with the first connecting block 1031, wherein the first connecting block 1031 is hingedly arranged inside the first groove body 1021, the second connecting block 1032 is used in conjunction with the second groove body 1022, and the mounting hole 104 is located on the second connecting block 1032;

[0033] This design makes it easy to store the first connection block 1031 through the first slot body 1021 and the second connection block 1032 through the second slot body 1022 in the storage slot, thereby reducing the occupied space.

[0034] The top of the first slot 1021 is closed, and when the second connecting block 1032 is in a horizontal state, the upper surface of the second connecting block 1032 is flush with the upper surface of the plate body 1;

[0035] This design makes it easy to increase the contact area between the plate body 1 and the installation position, thereby improving the stability after installation.
