DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in 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.

[0024] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0025] Reference Figure 1-Figure 4 As shown, a hoisting power supply includes a fixed frame 1, a movable platform 2 is slidably provided on the fixed frame 1, and the movable platform 2 can be moved on the fixed frame 1, so that it can be adjusted as needed, a winding component 5 is provided on the movable platform 2, a cable 3 is wound on the winding component 5, and a power supply body 4 is provided at one end of the cable 3 away from the winding component 5, so that when not in use, the cable 3 can be wound by the winding component 5, and the power supply body 4 can be put away, and it also includes:

[0026] The tightening component 6 is arranged between the winding component 5 and the power source body 4. The tightening component 6 itself has a certain elasticity and is used to tighten the cable 3. When the winding component 5 winds up the cable 3, if the device is still connected to the power source body 4, the cable 3 will be tightened, and the tightening component 6 can be contracted to a certain extent to prevent the cable 3 from being pulled;

[0027] The alarm component 7 is arranged on the tightening component 6. After the tightening component 6 is tightened, the alarm component 7 will be activated to issue an early warning and directly close the winding component 5.

[0028] In one embodiment, the winding assembly 5 includes a fixed housing 51 fixed on the movable platform 2, a winding roller 52 is rotatably arranged in the fixed housing 51, the cable 3 is wound on the winding roller 52, and a driving motor 53 for driving the winding roller 52 to rotate is arranged on the fixed housing 51;

[0029] When winding, the winding roller 52 is driven to rotate by the driving motor 53 , which pulls the cable 3 so that the cable 3 is wound around the winding roller 52 .

[0030] In one embodiment, a protective shell 54 is fixedly provided at the bottom of the fixed shell 51 . Two pressing rollers 55 are rotatably provided inside the protective shell 54 . The cable 3 is located between the two pressing rollers 55 . The two pressing rollers 55 are used to guide the cable 3 .

[0031] In one embodiment, the tightening assembly 6 includes a mounting frame 61 fixedly connected to the winding assembly 5, a first guide roller 62 is rotatably provided in the mounting frame 61, first movable plates 63 are rotatably provided on both sides of the first guide roller 62, a second guide roller 64 is rotatably provided on one end of the first movable plate 63 away from the first guide roller 62, second movable plates 65 are rotatably provided on both sides of the second guide roller 64, a lifting platform 66 is rotatably provided on one end of the second movable plate 65 away from the second guide roller 64, the lifting platform 66 is slidably connected to the mounting frame 61, the cable 3 passes through the first guide roller 62, the second guide roller 64 and the lifting platform 66 in sequence, and the alarm assembly 7 is arranged on the lifting platform 66;

[0032] If the device is also connected to the power source body 4, when the cable 3 is reeled up, the cable 3 will squeeze the second guide roller 64, and the second guide roller 64 will push the lifting platform 66 downward through the second movable plate 65, which has a certain protective effect on the cable 3 and prevents the cable 3 from being pulled hard and causing damage. After the lifting platform 66 moves down, the alarm component 7 will be activated. When the alarm component 7 sounds an alarm, it will also directly cut off the power to the reeling component 5 to prevent the cable 3 from being pulled further.

[0033] In one embodiment, two fixed plates 662 are provided on one side of the lifting platform 66, and third guide rollers 663 are rotatably provided in the two fixed plates 662. A slide bar 664 is provided in the mounting frame 61. Lifting sliders 661 sleeved on the slide bar 664 are also provided at both ends of the lifting platform 66. A limit spring 665 sleeved on the slide bar 664 is provided on one side of the lifting slider 661.

[0034] When the lifting platform 66 moves downward, it will drive the lifting slider 661 to compress the limit spring 665. Normally, the limit spring 665 is in a relaxed state, so that the lifting platform 66 is located at the upper end of the mounting frame 61. At the same time, the second guide roller 64 also extends outward, which will cause a certain folding of the cable 3. When the cable 3 is tightened, the fold will be straightened, thereby avoiding direct pulling on the cable 3 and protecting the cable 3 to a certain extent.

[0035] In one embodiment, the alarm assembly 7 includes a pressure rod 71 fixed on the lifting platform 66, and an alarm 72 is provided at the bottom of the mounting frame 61, and the alarm 72 is located directly below the pressure rod 71;

[0036] When the lifting platform 66 moves downward, the pressure rod 71 will be driven to move downward together until the pressure rod 71 touches the alarm 72, and the alarm 72 will sound an alarm, and at the same time, the power of the winding component 5 will be directly cut off to protect the cable 3.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
